Description

Technical Field

[0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a dewatering device for interlayer stacked paving materials, and also relates to a paving method for the dewatering device for interlayer stacked paving materials. Background Art

[0002] As the amount of urban sewage continues to grow, the number of corresponding sewage treatment facilities has also increased, and the amount of residual sludge, a byproduct of sewage treatment, has also increased. How to properly handle and dispose of these sludges that are constantly generated and increasing in quantity has become an urgent problem to be solved in my country's environmental protection. The moisture content of residual sludge is generally above 80%. Sludge dehydration is a key step in its treatment process. However, the difficulty of deep dehydration of sludge has become a bottleneck problem restricting the harmless and resource-based treatment of sludge.

[0003] There are many methods for solid-liquid separation, including pressing, extrusion, centrifugation, etc., and the corresponding solid-liquid separation equipment is also diverse. Among them, the stacking extrusion device has the characteristics of high extrusion pressure, high extrusion limit, and long extrusion time, and has a good dehydration effect, so it is widely used. The filter cloth of the stacking extrusion device is generally an ultra-long continuous filter cloth. During the working process, multiple layers of filter cloth need to be stacked and spread, and the sludge needs to be evenly laid between the filter cloths. When stacking filter cloths and laying materials, a cloth pressing assembly is required to fix the filter cloth. It is mainly composed of two sets of front and rear cloth pressing assemblies. During the laying process, the filter cloth is fixed by the front and rear sets of cloth pressing assemblies. Specifically, the proximal end of the filter cloth is first pressed by the front cloth pressing assembly, and the discharge port of the sludge spreading mechanism is used to push the filter cloth forward. When the sludge spreading mechanism reaches the farthest limit position, the rear cloth pressing assembly presses the far end of the filter cloth, and then the sludge spreading mechanism retreats. When the discharge port of the sludge spreading mechanism exits the filter cylinder, the front cloth pressing assembly is pulled out from both sides of the filter cloth and pressed onto the upper layer of filter cloth.

[0004] The front cloth pressing assembly and the rear cloth pressing assembly of the existing stacking and squeezing device are generally arranged above the filter cylinder and driven by a lifting mechanism arranged above the filter cylinder. For example, in the Chinese utility model patent with application number CN202023099235.0, a fixing device for stacked filter cloth paving is disclosed, in which the front pressure rod lifting frame of the front pressure rod mechanism is driven by the front pressure rod lifting mechanism to move up and down on the front pressure rod fixing frame, the front pressure rod guide device is installed on both sides of the front pressure rod fixing frame, the front pressure rod horizontal telescopic mechanism is fixed on the front pressure rod lifting frame, a horizontal pressure rod is installed on the outside of the front pressure rod horizontal telescopic mechanism, and the horizontal pressure rod is driven by the front pressure rod horizontal telescopic mechanism to move horizontally left and right relative to the front pressure rod lifting frame. The rear pressure rod lifting frame of the rear pressure rod mechanism is driven by the rear pressure rod lifting mechanism to move up and down on the rear pressure rod fixing frame, and the rear pressure rod guide device is installed on both sides of the rear pressure rod lifting frame.

[0005] However, in the above arrangement, the front cloth pressing assembly and the rear cloth pressing assembly are arranged above the filter cylinder, which is not conducive to maintenance, and will occupy a large space above the filter cylinder, and easily interfere with other devices above the filter cylinder (such as extrusion equipment).

[0006] Therefore, designing a dewatering device for stacking materials in layers that is easy to maintain and avoids interference between the cloth pressing assembly and other devices (such as extrusion equipment) above the filter cylinder has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0021] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0022] 1. The present invention arranges the cloth pressing assembly on the peripheral side of the filter cylinder, which reduces the installation height of the cloth pressing assembly and facilitates operators to install and maintain the cloth pressing assembly. At the same time, the cloth pressing assembly will not occupy a large area of ​​space above the filter cylinder, and can avoid the problem of interference between the cloth pressing assembly and other devices such as the extrusion equipment above the filter cylinder.

[0023] 2. In the present invention, during the process of the driving member of the first cloth pressing assembly moving toward the direction close to the filter cylinder, the driving member pushes the pressure rod to feed toward the direction close to the filter cylinder, and during the process of the driving member driving the connecting rod to rotate, the connecting rod drives the pressure rod to slide along the slide rail, and the connecting rod can drive the pressure rod to press the filter cloth onto the filter cylinder. Thus, the pressure rod can be driven to feed toward the direction close to the filter cylinder and press downward by a power source, which reduces the power source used to drive the first cloth pressing assembly, is beneficial to reducing the cost of the equipment, and simplifies the control system of the first cloth pressing assembly.

[0024] 3. When the movable part of the second cloth pressing assembly of the present invention drives the cloth pressing rod to loosen the filter cloth, the end of the cloth pressing rod moves upward and away from the filter cloth. When the movable part drives the cloth pressing rod to press the filter cloth, the end of the cloth pressing rod moves downward and toward the filter cylinder, instead of only driving the cloth pressing rod to rise and fall in the vertical direction. This enables the cloth pressing rod to effectively avoid the front end in the feeding direction of the cloth pushing and spreading device, which is beneficial to shortening the stroke of the cloth pressing rod during the cloth pressing process.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0046] like Figures 1 to 17 As shown, in the embodiment of the present invention, a dewatering device for interlayer stacked paving is introduced, including a cloth pushing and paving device 1 and a filter cylinder 2. The cloth pushing and paving device 1 lays a filter cloth 71 in the filter cylinder 2 and sprays the material to be processed onto the filter cloth 71. During the paving process, the filter cloth 71 is fixed by two sets of cloth pressing assemblies.

[0047] In some specific embodiments, the cloth pushing and spreading device 1 is configured to move back and forth between the first side and the second side of the filter cylinder 2 to fold the filter cloth 71 and spray the material to be processed onto the filter cloth 71 .

[0048] In the moving direction of the filter cloth 71 , a first cloth pressing assembly 5 and a second cloth pressing assembly 6 are respectively provided on the first side edge and the second side edge opposite to the top of the filter cylinder 2 .

[0049] The dewatering equipment for interlayer stacked materials also includes a filter cloth placing and unloading and winding device, which includes a unloading component for unloading the dry material after extrusion and dehydration from the filter cloth 71, a filter cloth finishing component for leveling and cleaning the filter cloth 71 from which the dry material has been unloaded, and a filter cloth unwinding and winding component for winding up the filter cloth 71 and placing the cloth.

[0050] The filter cloth reeling and unreeling assembly includes a cloth reeling roller 7, on which the filter cloth 71 is rolled up. The cloth reeling roller 7 containing the filter cloth 71 and the cloth pushing and spreading device 1 are located on the same side of the filter cylinder 2, and the spreading opening of the cloth pushing and spreading device 1 is higher than the upper edge of the filter cylinder 2.

[0051] During the process of laying the filter cloth 71 from the first side to the second side of the filter cylinder 2, when the cloth pushing and spreading device 1 is outside the filter cylinder 2, the first cloth pressing assembly 5 presses the filter cloth 71 on the first side down on the filter cylinder 2; the cloth pushing and spreading device 1 moves toward the second side of the filter cylinder 2 against the filter cloth 71, and at the same time, spreads the material evenly on the filter cloth 71, and the filter cloth 71 is unwound from the cloth winding roller 7; when the front end of the cloth pushing and spreading device 1 along the feeding direction reaches the second side of the filter cylinder 2, the second cloth pressing assembly 6 presses the filter cloth 71 on the second side down on the filter cylinder 2, and the cloth pushing and spreading device 1 retreats to the outside of the first side of the filter cylinder 2.

[0052] During the retraction process of the cloth pushing and spreading device 1, and / or when the cloth pushing and spreading device 1 exits the filter cylinder 2, the pressing rods of the first cloth pressing assembly 5 are pulled out from both sides of the filter cloth; when the cloth pushing and spreading device 1 exits the filter cylinder 2, the first cloth pressing assembly 5 is activated again to press the filter cloth 71 on the first side down on the filter cylinder 2.

[0053] By repeating the movement, several layers of the material to be processed wrapped by the filter cloth 71 are laid up and down in the filter cylinder 2 .

[0054] It also includes an extrusion device 8, which is located above the filter cylinder 2 and is used to extrude the material.

[0055] After the extrusion is completed, the cloth unloading process begins. The cloth roll roller 7 in the filter cloth unloading and unloading reeling device rotates under the drive of the motor, driving the filter cloth 71 to move and recover the filter cloth 71; the material after extrusion and dehydration is carried on the filter cloth 71, and leaves the filter cylinder 2 with the filter cloth 71 and enters the filter cloth unloading and unloading reeling device. After being unloaded by the unloading assembly, the dehydrated material falls into the discharge collection hopper 3 below, and the filter cloth 71 is cleaned and leveled by the filter cloth finishing assembly and then rolled up on the cloth roll roller 7.

[0056] The material to be processed is a mixture of solid and liquid, for example, a water-containing material, and there is no limitation on the water content.

[0057] In this embodiment, the dewatering equipment for interlayer stacked materials is preferably used for solid-liquid separation of sludge with high water content.

[0058] In this embodiment, in order to ensure the wrapping of the material, the width of the filter cloth 71 is set to be greater than the width of the internal space of the filter cylinder 2, and the width of the material spreading opening of the cloth pushing and spreading device 1 is less than or equal to the width of the internal space of the filter cylinder 2. After the cloth pushing and spreading device 1 spreads the material on the filter cloth 71, the movable bottom plate of the filter cylinder 2 moves downward, and the filter cloth 71 carrying the material falls into the filter cylinder 2. The side of the filter cloth 71 is bent upward under the obstruction of the filter cylinder 2, and the material is wrapped from both sides of the material to prevent the material from flowing out from both sides of the filter cloth 71.

[0059] In some preferred embodiments, there is a certain interval between the cloth pressing position of the first cloth pressing assembly 5 and the internal space of the filter cylinder 2. Therefore, when the movable bottom plate of the filter cylinder 2 moves downward, the part of the filter cloth 71 that exceeds the internal space of the filter cylinder 2 is bent upward under the obstruction of the first side of the filter cylinder 2, so that the side of the material close to the cloth pushing and spreading device 1 is also wrapped by the filter cloth 71.

[0060] Embodiment 1

[0061] In the prior art, the cloth pressing assembly is usually arranged above the filter cylinder and driven by a lifting mechanism. The installation position is high, which is not conducive to installation and maintenance, and will occupy a large space above the filter cylinder, which is easy to interfere with other devices such as the extrusion equipment above.

[0062] like Figures 1 to 17 As shown, in an embodiment of the present invention, a dewatering device for interlayer stacked materials is introduced to solve the above problems.

[0063] The dewatering equipment for interlayer stacked paving includes a filter cylinder 2, a cloth pushing and paving device 1, a cloth pressing assembly and a filter cloth placing and unloading and winding device, wherein the filter cloth placing and unloading and winding device and the cloth pushing and paving device 1 are arranged on the same side of the filter cylinder 2 and supported by a frame 4. The filter cloth placing and unloading and winding device includes a unloading assembly, a filter cloth finishing assembly and a filter cloth unwinding and winding assembly. The cloth winding roller 7 of the filter cloth unwinding and winding assembly is installed on the frame 4, and the filter cloth 71 is rolled up on the cloth winding roller 7. The filter cloth finishing assembly includes a plurality of cloth guide rollers 41 disposed between the cloth winding roller 7 and the filter cylinder 2. The cloth guide rollers 41 and the cloth winding rollers 7 are both rotatably mounted on the frame 4. The cloth guide rollers 41 are parallel to the cloth winding rollers 7, and the cloth guide rollers 41 and the cloth winding rollers 7 are aligned in the axial direction. The filter cloth 71 passes through each cloth guide roller 41 in turn, extending from the top of the cloth pushing and spreading device 1 to the front side of the cloth pushing and spreading device 1 along the feeding direction, and the cloth pressing assembly presses the filter cloth 71 against the filter cylinder 2. The cloth pushing and spreading device 1 reciprocates above the filter cylinder 2 in the horizontal direction, lays the filter cloth 71 in layers in the filter cylinder 2, and sprays and discharges materials onto the filter cloth 71.

[0064] like Figure 4 As shown, the cloth pressing assembly includes a first cloth pressing assembly 5 arranged on a first side edge at the top of the filter cylinder 2 and a second cloth pressing assembly 6 arranged on a second side edge opposite to the first side edge, and the first side edge and the second side edge are arranged along the feeding direction of the cloth pushing and spreading device 1. The first cloth pressing assembly 5 is arranged at the end of the first side edge, and the second cloth pressing assembly 6 is arranged at the middle of the outer wall of the second side edge, that is, arranged at the middle of the second side edge away from the first side edge. That is, arranging the cloth pressing assembly on the peripheral side of the filter cylinder 2 reduces the installation height of the cloth pressing assembly, which is convenient for operators to install and maintain the cloth pressing assembly. At the same time, the cloth pressing assembly will not occupy a large area of ​​the space above the filter cylinder 2, and can avoid the problem of interference between the cloth pressing assembly and other devices such as the extrusion device 8 above the filter cylinder 2.

[0065] In some specific embodiments, the first cloth pressing assembly 5 is arranged in pairs at the two ends of the first side, including a pressing rod 51 arranged parallel to the first side, and a driving transmission device 52 for driving the pressing rod 51 to move horizontally along the first side, and to move up and down relative to the first side. The second cloth pressing assembly 6 is isolatedly arranged in the middle of the outer wall of the second side, including a fixed part 61, and a movable part 62 that rotates with the fixed part 61, and the movable part 62 includes a cloth pressing rod 622, and the cloth pressing rod 622 rotates with the rotating shaft 621 of the movable part 62 to press / loosen the filter cloth 71.

[0066] Specifically, the filter cylinder 2 includes a cylinder body 21 and a movable bottom plate 22 located in the cylinder body 21. The cylinder body 21 is a hollow cubic structure with water outlet holes on the sides. The top of the cylinder body 21 is open, and the movable bottom plate 22 matches the cross section of the inner cavity of the cylinder body 21 and can move up and down along the cylinder body 21. The bottom of the cylinder body 21 is open. A lifting device is arranged below the cylinder body 21, and the lifting device extends into the cylinder body 21 to lift the movable bottom plate 22 up or down. The top of the cylinder body 21 is open, and the top of the cylinder body 21 on the side where the opening is close to the cloth-pushing and spreading device 1 is the first side of the filter cylinder 2, and the top of the cylinder body 21 on the side where the opening is away from the cloth-pushing and spreading device 1 is the second side of the filter cylinder 2. The first side and the second side extend in the horizontal direction and are flush with each other in the horizontal direction. The length direction of the first side and the second side is perpendicular to the feeding direction of the cloth-pushing and spreading device 1, and the first side and the second side have a certain width in the feeding direction of the cloth-pushing and spreading device 1. The first cloth pressing assembly 5 and the second cloth pressing assembly 6 press the filter cloth 71 tightly onto the first side edge and the second side edge respectively.

[0067] like Figures 5 to 10 As shown, in some specific embodiments, the pressure rod 51 includes a first position and a second position. The first position is the position where the pressure rod 51 presses the filter cloth 71 onto the filter cylinder 2, and the second position is the position where the projection of the pressure rod 51 in the horizontal direction falls outside the filter cloth 71. The driving transmission device 52 is used to drive the pressure rod 51 to move between the first position and the second position.

[0068] The driving transmission device 52 is arranged on the outer side of the upper edge of the filter cylinder 2, and includes a support seat extending in a direction parallel to the first side, a connecting rod 522 hinged at one end on the support seat, a connecting rod 523 hinged at the other end of the connecting rod 522, and a driving member 524 arranged on the side of the connecting rod 522 away from the filter cylinder 2. The hinge axis between the connecting rod 522 and the support frame 521 and the hinge axis between the connecting rod 522 and the connecting rod 523 are parallel to each other and perpendicular to the length direction of the first side. The end of the pressure rod 51 away from the filter cylinder 2 is connected to the driving member 524, and can slide on the driving member 524 in a vertical direction perpendicular to the pressure rod 51. The connecting rod 523 is connected to the middle part of the pressure rod 51 and can slide along the length direction of the pressure rod 51. The power source 53 which can be horizontally extended and retracted along the first side edge drives the driving member 524 to move horizontally. When the driving member 524 drives the pressure rod 51 to move horizontally, the pressure rod 51 is driven to move up and down through the connecting rod 522 and the connecting rod 523 .

[0069] Specifically, the extension direction of the pressure rod 51 is parallel to the extension direction of the support frame 521 and parallel to the length direction of the first side. The extension direction of the connecting rod 523 is parallel to the length direction of the first side and is cylindrical. The connecting rod 523 is sleeved in the middle of the pressure rod 51 and can slide along the length direction of the pressure rod 51.

[0070] The driving member 524 is slidably connected to the pressure rod 51 through a guide assembly 54, which includes a slide rail 541 provided on the driving member 524, the slide rail 541 extending in the vertical direction, and a slide sleeve 542 provided at one end of the pressure rod 51 away from the filter cylinder 2 corresponding to the slide rail 541, the slide sleeve 542 being sleeved on the slide rail 541. The driving member 524 also includes an abutment portion 5241, which is arranged opposite to the side of the connecting rod 522 away from the filter cylinder 2. When the driving member 524 moves toward the filter cylinder 2, the driving member 524 pushes the pressing rod 51 to slide along the connecting rod 523 through the guide assembly 54, and feeds toward the filter cylinder 2. In this process, the connecting rod 522 is driven to rotate by the abutment portion 5241. Under the limiting and guiding action of the guide assembly 54, the pressing rod 51 slides up and down along the slide rail 541 without rotating, so that the distance between the connecting rod 523 and the support frame 521 can be changed, that is, the pressing rod 51 moves in the vertical direction. Driven by the connecting rod 523, the pressing rod 51 presses the filter cloth 71 against the filter cylinder 2.

[0071] Thus, a power source 53 can be used to drive the driving member 524 to reciprocate in the direction of approaching and moving away from the filter cylinder 2, so that the pressing rod 51 can be fed and pressed down in the direction of approaching the filter cylinder 2, and the pressing rod 51 can be moved back and lifted up in the direction away from the filter cylinder 2, so as to realize the movement of the pressing rod 51 between the first position and the second position, thereby reducing the power source 53 used to drive the pressing rod 51, which is conducive to reducing the cost of the equipment and simplifying the control system of the first cloth pressing assembly 5. By setting the connecting rod 523 to be cylindrical, the force applied by the driving transmission device 52 to the pressing rod 51 can be applied to a certain section of the pressing rod 51 instead of a certain point on the pressing rod 51, so that the pressing rod 51 can be translated and pressed down as a whole, so as to avoid the situation that the end of the pressing rod 51 away from the driving transmission device 52 is easy to tilt when the pressing rod 51 is pressing the filter cloth 71, thereby improving the pressing effect on the filter cloth 71.

[0072] The power source 53 can be a retractable device, specifically, a cylinder, a hydraulic cylinder, etc., or a linear motor, etc. It only needs to be able to drive the driving member 524 to move back and forth in the horizontal direction close to and away from the filter cylinder 2.

[0073] In this embodiment, a force storage structure 525 is provided between the connecting rod 522 and the support frame 521. When the driving member 524 moves toward the direction approaching the filter cylinder 2 and drives the connecting rod 522 to rotate toward the filter cylinder 2, the force storage structure 525 stores force; when the driving member 524 moves toward the direction away from the filter cylinder 2, the force storage structure 525 is released, driving the connecting rod 522 to rotate in the direction away from the filter cylinder 2.

[0074] In some preferred embodiments, during the process of the driving member 524 moving toward the filter cylinder 2, there are a first working state in which the abutting portion 5241 and the connecting rod 522 are spaced apart, and a second working state in which the abutting portion 5241 and the connecting rod 522 are slidably matched to drive the connecting rod 522 to rotate toward the filter cylinder 2. Specifically, the first working state of the driving member 524 is that the abutting portion 5241 and the connecting rod 522 are spaced apart; the second working state of the driving member 524 is that the abutting portion 5241 and the connecting rod 522 are slidably matched to drive the connecting rod 522 to rotate toward the filter cylinder 2.

[0075] During the process of the driving member 524 moving toward the filter cylinder 2, when it is in the first working state, the driving member 524 only drives the pressing rod 51 to feed toward the filter cylinder 2, and when it is in the second working state, the driving member 524 not only drives the pressing rod 51 to feed toward the filter cylinder 2, but also drives the connecting rod 522 to rotate toward the filter cylinder 2, and drives the pressing rod 51 to move downward through the connecting rod 523. Therefore, the length of the pressing rod 51 feeding toward the filter cylinder 2 can be increased or shortened by setting the path length of the driving member 524 in the first working state during the process of moving toward the filter cylinder 2. Preferably, when the driving member 524 is in the first working state, the horizontal distance between the sliding sleeve 542 and the connecting rod 523 away from one end of the filter cylinder 2 is greater than or equal to the horizontal distance between the abutment portion 5241 and the connecting rod 522.

[0076] The force storage structure 525 can be a torsion spring arranged at the hinge axis of the connecting rod 522, or a compression spring or a tension spring arranged between the connecting rod 522 and the support frame 521, as long as it can drive the connecting rod 522 to rotate in a direction away from the filter cylinder 2.

[0077] Preferably, the force storage structure 525 is configured as a spring-type telescopic rod, which is arranged on the side of the connecting rod 522 close to the filter cylinder 2, one end of the spring-type telescopic rod is hinged to the support frame 521, and the other end is hinged to the connecting rod 522. When the driving member 524 drives the connecting rod 522 to rotate in the direction close to the filter cylinder 2, the spring-type telescopic rod contracts, and the spring inside the spring-type telescopic rod stores force. When the driving member 524 moves in the direction away from the filter cylinder 2, the spring-type telescopic rod extends, driving the connecting rod 522 to reset. In this process, the connecting rod 523 drives the pressure rod 51 to move upward.

[0078] In this embodiment, the support frame 521 of the driving transmission device 52 can be a part of the frame 4 for carrying the cloth pushing and spreading device 1, or can be set on the filter cylinder 2, or can be set separately. The pressure rod 51 can be set above the support frame 521, or the pressure rod 51 can be set below the support frame 521, and it is only necessary to ensure that when the connecting rod 522 rotates in the direction close to the filter cylinder 2, the connecting rod 523 can drive the pressure rod 51 to press down and press the filter cloth 71 on the filter cylinder 2, and when the connecting rod 522 rotates in the direction away from the filter cylinder 2, the connecting rod 523 can drive the pressure rod 51 to lift up.

[0079] If the pressing rod 51 is arranged above the support frame 521, when the pressing rod 51 moves to the first position, the connecting rod 522 is inclined from bottom to top toward the filter cylinder 2. If the pressing rod 51 is arranged below the support frame 521, when the pressing rod 51 moves to the first position, the connecting rod 522 is inclined from bottom to top toward the filter cylinder 2. Through the above arrangement, it can be ensured that when the connecting rod 523 moves to the first position, the feeding length of the pressing rod 51 toward the top of the filter cylinder 2 is the maximum, and it can be ensured that the driving transmission device 52 can convert the force provided by the power source 53 into the pressing force of the pressing rod 51 on the filter cloth 71. Preferably, when the driving member 524 is in the first working state, the connecting rod 522 extends obliquely from bottom to top toward the filter cylinder 2.

[0080] In some preferred embodiments, the pressure rod 51 is arranged just above the support frame 521, so that the force application point of the connecting rod 523 on the pressure rod 51 can be closer to the filter cylinder 2, further improving the pressing effect on the filter cloth 71. Preferably, the driving transmission device 52 is arranged near the upper edge of the filter cylinder 2, the support frame 521 is arranged below the upper edge of the filter cylinder 2, and the connecting rod 523 is arranged above the upper edge of the filter cylinder 2, so that the force application effect of the driving transmission device 52 on the pressure rod 51 can be improved, and the structure of the dewatering device for interlayer stacking can be made compact.

[0081] In some preferred embodiments, the pressing rod 51 is configured as a straight rod parallel to the top of the filter cylinder 2 and extending along the length direction of the first side.

[0082] In some specific embodiments, the support frame 521 is provided with a support frame 5211 protruding in a direction close to the connecting rod 523 and extending in a direction parallel to the connecting rod 523, and the driving member 524 is slidably provided on the support frame 5211, and the support frame 5211 supports and guides the driving member 524. The connecting rod 523 is provided above the support frame 521, and the vertical distance between the end of the pressure rod 51 close to the filter cylinder 2 and the top of the filter cylinder 2 is less than or equal to the vertical distance between the end of the pressure rod 51 away from the filter cylinder 2 and the top of the support frame 5211.

[0083] Preferably, when the pressing rod 51 presses the filter cloth 71 against the top of the filter cylinder 2, the end of the pressing rod 51 away from the filter cylinder 2 abuts against the top of the support frame 5211, thereby further improving the horizontality of the pressing rod 51 and improving the pressing effect on the filter cloth 71. Preferably, when the pressing rod 51 is in the first position, the connecting rod 523 and the support frame 5211 are mutually offset in the length direction of the pressing rod 51 to avoid mutual interference.

[0084] In this embodiment, the slide rail 541 and the abutment portion 5241 are staggered along the length direction of the connecting rod 523 . The slide rail 541 is arranged at one end of the driving member 524 close to the filter cylinder 2 , and the abutment portion 5241 is arranged at one end of the driving member 524 away from the filter cylinder 2 .

[0085] In some preferred embodiments, the connecting rod 522 includes a first rod portion and a second rod portion clamped on both sides of the connecting rod 523, the upper ends of the first rod portion and the second rod portion are respectively hinged to the left and right sides of the connecting rod 523, and the lower ends of the first rod portion and the second rod portion are respectively hinged to the left and right sides of the support frame 521, and a gap is formed between the first rod portion and the second rod portion. The support frame 5211 is arranged at the gap between the first rod portion and the second rod portion, protrudes upward from the support frame 521, and extends along the length direction of the support frame 521. The driving member 524 is arranged at the top of the support frame 5211 and slides with the top of the support frame 5211.

[0086] The driving member 524 extends along the length direction of the support frame 5211, and a slide rail 541 extending upward in the vertical direction is provided at one end of the driving member 524 close to the filter cylinder 2, and a first abutting portion 5241 and a second abutting portion 5241 extending downward from the left and right sides of the support frame 5211 are provided at one end of the driving member 524 away from the filter cylinder 2, and the first abutting portion 5241 and the second abutting portion 5241 respectively correspond to the side of the first rod portion and the second rod portion away from the filter cylinder 2. Preferably, the surface of the driving member 524 for abutting against the connecting rod 522 is set as an arc surface.

[0087] The connecting rod 522 may be provided as one or a group, or may be provided as a plurality or a plurality of groups arranged at intervals along the length direction of the connecting rod 523. When the connecting rod 522 is provided as a plurality or a plurality of groups, each connecting rod 522 is of equal length and parallel to each other. Specifically, the connecting rod 522 is provided as a plurality of groups arranged at intervals along the length direction of the connecting rod 523, each connecting rod 522 is of equal length and parallel to each other, and the plurality of connecting rods 522 may be a plurality of first rod portions or second rod portions. Alternatively, the connecting rod 522 is provided as a plurality of groups arranged at intervals along the length direction of the connecting rod 523, each group of connecting rods 522 is of equal length and parallel to each other, and each group of connecting rods 522 includes a first rod portion and a second rod portion clamped on both sides of the connecting rod 523.

[0088] Preferably, the connecting rod 522 is provided with two parallel groups of equal length, which are respectively connected between the two ends of the connecting rod 523 and the support frame 521, forming a parallelogram mechanism on the support frame 521 to ensure the reliability of driving the pressure rod 51.

[0089] In some preferred embodiments, when the pressure rod 51 is in the first position, the angle between the connecting rod 522 and the horizontal direction is less than or equal to 45°, so that the parallelogram mechanism can convert more of the driving force of the driving member 524 on the connecting rod 522 into downward pressure on the pressure rod 51, thereby improving the clamping effect on the filter cloth 71.

[0090] In this embodiment, the length direction of the support frame 521, the length direction of the support frame 5211, the length direction of the connecting rod 523, and the length direction of the pressure rod 51 are all parallel to the length direction of the first side.

[0091] Preferably, the first cloth pressing assembly 5 further includes a limiting member 55 extending in the vertical direction. The limiting member 55 is disposed on both sides of the pressing rod 51 along the length direction of the pressing rod 51 and fits with both sides of the pressing rod 51 . Specifically, the limiting member 55 includes a first limiting member 551 and a second limiting member 552. The first limiting member 551 is arranged on the side of the pressure rod 51 toward the laying direction of the filter cloth 71, that is, arranged on the side of the pressure rod 51 away from the cloth pushing and spreading device 1, and is in contact with the side of the pressure rod 51 toward the laying direction of the filter cloth 71. The second limiting member 552 is arranged on the side of the pressure rod 51 opposite to the laying direction of the filter cloth 71, that is, arranged on the side of the pressure rod 51 close to the cloth pushing and spreading device 1, and is in contact with the side of the pressure rod 51 opposite to the laying direction of the filter cloth 71. The pressure rod 51 is arranged between the first limiting member 551 and the second limiting member 552, and the pressure rod 51 passes through the gap between the first limiting member 551 and the second limiting member 552 to press the filter cloth 71. Therefore, when the pressure rod 51 tends to deflect in the horizontal direction due to the pulling force in the horizontal direction, the first limiting member 551 and the second limiting member 552 stop the pressure rod 51 from both sides of the pressure rod 51 to prevent it from rotating.

[0092] Preferably, the limiting member 55 includes a first plate 55-1 and a second plate 55-2. Specifically, the first plates 55-1 of the first limiting member 551 and the second limiting member 552 extend in the vertical direction, and the first plates 55-1 of the first limiting member 551 and the second limiting member 552 are arranged opposite to each other and spaced apart from each other. The space between the first plates 55-1 of the first limiting member 551 and the second limiting member 552 is used for the pressure rod 51 to pass through, and the second plates 55-2 of the first limiting member 551 and the second limiting member 552 extend horizontally from the bottom of the first plates 55-1 of the second limiting member 551 and the second limiting member 552 in directions away from each other.

[0093] Preferably, a reinforcing rib 55-3 is provided between the first plate 55-1 and the second plate 55-2.

The side of the reinforcing rib 55-3 close to the first plate 55-1 is connected to the first plate 55-1.

[0094] Preferably, the limiting member 55 is arranged at one end of the support seat close to the filter cylinder 2 , and the first limiting member 551 and the second limiting member 552 are arranged as an integral part with the support frame 521 .

[0095] Preferably, the pressure rod 51 is configured to be flat and parallel to the top of the filter cylinder 2. The side of the pressure rod 51 opposite to the top of the filter cylinder 2 is configured to be a plane parallel to the top of the filter cylinder 2.

[0096] Preferably, the pressing rod 51 of the first cloth pressing assembly 5 corresponds to the open side of the first side of the filter cylinder 2 close to the top of the cylinder body 21 in the vertical direction. Along the feeding direction of the cloth pushing and spreading device 1, the first cloth pressing assembly 5 is arranged on the outer side walls on the left and right sides of the filter cylinder 2, and one end of the support seat close to the filter cylinder 2 is close to the outer side wall of the filter cylinder 2. Specifically, the filter cylinder 2 includes a third side and a fourth side perpendicular to the first side and the second side, the first cloth pressing assembly 5 is arranged outside the third side and / or the fourth side, and the extension direction of the pressing rod 51 is arranged perpendicular to the third side and the fourth side. The two first cloth pressing assemblies 5 are respectively arranged outside the third side and the fourth side, and the pressing rod 51 of the first cloth pressing assembly 5 corresponds to the open side of the first side close to the top of the cylinder body 21, which can improve the utilization rate of the filter cloth.

[0097] like Figures 11 to 13 As shown, in some specific embodiments, the movable portion 62 of the second cloth pressing assembly 6 includes a rotating shaft 621 that is rotatably matched with the fixed portion 61, and a cloth pressing rod 622 disposed on the rotating shaft 621. The rotating shaft 621 is disposed on the outer side of the upper edge of the filter cylinder 2, higher than the top of the filter cylinder 2, and extends along the length direction of the second side edge. The cloth pressing rod 622 extends in a direction perpendicular to the rotating shaft 621. The cloth pressing rod 622 is provided with at least two cloth pressing rods 622 that are spaced apart along the axial direction of the rotating shaft 621. The cloth pressing rod 622 rotates with the rotating shaft 621 to press / loosen the filter cloth 71.

[0098] The cloth pressing rods 622 are parallel to each other and have the same length, and one end of each cloth pressing rod 622 away from the rotating shaft 621 simultaneously presses the filter cloth 71. The cloth pressing rods 622 press the filter cloth 71 at the left and right sides of the filter cloth 71 close to the laying direction, which can ensure the fixing effect of the filter cloth 71 and help prevent the material on the filter cloth 71 from flowing out from the two sides of the filter cloth 71.

[0099] The cloth pressing rod 622 presses the filter cloth 71 onto the second side. Preferably, the end of the cloth pressing rod 622 , which faces the second side, is arranged as a plane parallel to the second side when the filter cloth 71 is pressed.

[0100] Specifically, the cloth pressing rod 622 extends as a whole along the radial direction of the rotating shaft 621, and includes a neck 6221 and a head 6222. The first end of the neck 6221 is connected to the rotating shaft 621, and the first end of the head 6222 is connected to the second end of the neck 6221. The first end of the head 6222 protrudes toward the second side relative to the second end of the neck 6221, and the side of the head 6222 toward the second side is set as a plane inclined in a direction away from the rotating shaft 621 and away from the second side.

[0101] Specifically, along the direction away from the rotation axis 621, the cross-sectional area of ​​the head 6222 gradually decreases, the cross-sectional area of ​​the first end of the head 6222 is greater than the cross-sectional area of ​​the second end of the head 6222, and the cross-sectional area of ​​the first end of the head 6222 is greater than the cross-sectional area of ​​the second end of the neck 6221. The left side surface of the neck 6221 and the head 6222 are coplanar, the right side surface is coplanar, and the side surface away from the second side is coplanar, so that the thickness of the head 6222 along the vertical direction perpendicular to the neck 6221 of the cloth pressing rod 622 to the head 6222 gradually decreases. Preferably, the end of the head 6222 has a certain thickness in the direction perpendicular to the cloth pressing rod 622, and the certain thickness can avoid forming a sharp angle at the second end of the head 6222. Preferably, the end of the head 6222 away from the rotation axis 621 is set to be an arc shape. Avoid the situation where the filter cloth 71 is pierced by the end of the cloth pressing rod 622.

[0102] The movable part 62 of the second cloth pressing assembly 6 is configured with a first position where the cloth pressing rod 622 rotates in the first direction to press the filter cloth 71 against the second side edge, and a second position where a certain interval is formed between the cloth pressing rod 622 and the second side edge when it rotates in the second direction. The certain interval enables the front end of the cloth pushing and spreading device 1 along the feeding direction to at least partially extend between the second side edge and the cloth pressing rod 622.

[0103] During the cloth pushing and spreading process, the filter cloth 71 is wrapped around the front end of the cloth pushing and spreading device 1 along the feeding direction. During the process in which the front end of the cloth pushing and spreading device 1 along the feeding direction pushes the filter cloth 71 and moves toward the second side of the filter cylinder 2, the movable portion 62 is in the second position, and a certain interval is formed between the cloth pressing rod 622 and the top of the filter cylinder 2. When the front end of the cloth pushing and spreading device 1 along the feeding direction pushes the filter cloth 71 and moves to the second side of the filter cylinder 2, the front end of the cloth pushing and spreading device 1 along the feeding direction at least partially extends to below the cloth pressing rod 622, the movable portion 62 rotates to the first position, and the cloth pressing rod 622 presses the filter cloth 71 against the second side of the filter cylinder 2. Specifically, when the front end of the cloth pushing and spreading device 1 along the feeding direction moves to the second side of the filter cylinder 2, the front end of the cloth pushing and spreading device 1 along the feeding direction at least partially overlaps with the moving path of the cloth pressing rod 622. During the process of the movable part 62 rotating to the first position, the cloth pressing rod 622 presses the filter cloth 71 covered on the front end of the cloth pushing and spreading device 1 along the feeding direction onto the second side of the filter cylinder 2.

[0104] In this embodiment, the front end of the cloth pushing and spreading device 1 is provided with a notch 1135 for the cloth pressing rod 622 to pass through, and the cloth pressing rod 622 passes through the notch 1135 to press the filter cloth 71 onto the filter cylinder 2. Specifically, the front end of the cloth pushing and spreading device 1 along the feeding direction is provided with a cloth pushing head 113, and two cloth pressing rods 622 correspond to the two ends extending along the length direction of the second side edge close to the cloth pushing head 113, and along the feeding direction of the cloth pushing and spreading device 1, the front end of the cloth pushing head 113 is provided with notches 1135 corresponding to the cloth pressing rods 622 one by one. The notch 1135 passes through the cloth pushing head 113 in the vertical direction, and the end of the cloth pressing rod 622 away from the rotating shaft 621 passes through the notch 1135 from top to bottom to press the filter cloth 71 covered on the cloth pushing head 113 onto the second side edge.

[0105] Preferably, the second cloth pressing assembly 6 further includes a driving member for driving the movable portion 62 to rotate, and the driving member is in transmission connection with the rotating shaft 621, and can drive the rotating shaft 621 to rotate in any manner. For example, the driving member can be a servo motor that drives the rotating shaft 621 through gears.

[0106] Preferably, the cloth pressing rod 622 is arranged on the side of the rotating shaft 621 close to the filter cylinder 2, and extends in a direction perpendicular to the rotating shaft 621. A driving rod 623 is arranged on the side of the rotating shaft 621 away from the filter cylinder 2, and the driving rod 623 is connected to the driving member in a transmission manner. The fixed part 61 is provided with a driving member in a transmission manner connected to the driving rod 623, and the driving member is a retractable device. The two ends of the retractable device are respectively rotatably matched with the fixed part 61 and the end of the driving rod 623.

[0107] Specifically, the telescopic device is fixedly mounted on the fixed portion 61, a bar hole is provided on the working end of the telescopic device, a rotating shaft is provided at the end of the driving rod 623, and the rotating shaft is installed in the bar hole. The length direction of the bar hole is perpendicular to the telescopic direction of the telescopic device. During the telescopic process of the telescopic device, the rotating shaft can slide along the bar hole to rotate the movable portion 62.

[0108] Preferably, the cloth pressing rod 622, the rotating shaft 621, and the driving rod 623 are integrally formed. The retractable device can be a cylinder, an oil cylinder, a linear motor, etc.

[0109] Preferably, the fixing portion 61 is arranged on the outer wall of the filter cylinder 2 away from the cloth pushing and spreading device 1, and includes a first support seat 611 and a second support seat 612. The first support seat 611 extends vertically along the length direction of the second side, and two mutually spaced shaft sleeves are arranged on the top of the first support seat 611, and the two ends of the rotating shaft 621 are respectively installed in the two shaft sleeves. The second support seat 612 is vertically arranged on the side of the first support seat 611 away from the second side, and the retractable device is arranged on the second support seat 612.

[0110] In an embodiment of the present invention, a material laying method of the dewatering equipment for stacking materials in interlayers is also provided, comprising the following steps:

[0111] S1: The first cloth pressing assembly 5 presses the filter cloth 71 against the first side; the movable bottom plate 22 of the filter cylinder 2 moves to be flush with the top of the filter cylinder 2, or the movable bottom plate 22 moves to be slightly lower than the top of the filter cylinder 2, and the interval between the movable bottom plate 22 and the top of the filter cylinder 2 is greater than or equal to the thickness of the material laid on the filter cloth 71;

[0112] S2: the cloth pushing and spreading device 1 feeds from the first side to the second side, pushes the filter cloth 71 to be spread from the first side to the second side, and sprays the material onto the filter cloth 71;

[0113] S3: the front end of the cloth pushing and spreading device 1 moves along the feeding direction to the upper side of the second side, and the second cloth pressing assembly 6 presses the filter cloth 71 onto the second side;

[0114] S4: the cloth pushing and spreading device 1 retreats from the second side edge, and during or after the retreat, the first cloth pressing assembly 5 is reset;

[0115] S5: When the front end of the cloth pushing and spreading device 1 moves to the outside of the first side along the feeding direction, the movable bottom plate 22 of the filter cylinder 2 moves downward by a stroke, so that the uppermost filter cloth 71 wrapped with the material falls into the filter cylinder 2, and the first cloth pressing assembly 5 moves again to press the filter cloth 71 at the first side;

[0116] Repeat steps S2 to S5. Thus, several layers of the material to be processed wrapped by the filter cloth 71 can be laid up and down in the filter cylinder 2.

[0117] In this embodiment, in step S5, the downward movement of the movable bottom plate 22 matches the sum of the thickness of the material laid on the filter cloth 71 and the thickness of the filter cloth 71. Specifically, two layers of filter cloth 71 are spaced between two adjacent layers of material.

[0118] Preferably, during the process of the cloth pushing and spreading device 1 retreating from the second side of the filter cylinder 2, the driving member 524 of the first cloth pressing assembly 5 moves in the direction away from the filter cylinder 2, and the cloth pushing and spreading device 1 is used to limit the lifting height of the pressing rod 51 during the process of pulling it out of the filter cloth 71.

[0119] Specifically, Figures 3 to 10 As shown, in the process of the cloth pushing and spreading device 1 retreating from the second side of the filter cylinder 2, the driving member 524 is controlled to move in the direction away from the filter cylinder 2, and the pressure rod 51 is pulled out of the filter cloth 71. During this process, the force storage structure 525 drives the connecting rod 522 to rotate in the direction away from the filter cylinder 2, and the connecting rod 523 drives the pressure rod 51 to lift up. When the pressure rod 51 is raised to abut against the bottom of the cloth pushing and spreading device 1, the connecting rod 523 no longer rises under the reaction force of the pressure rod 51, and the pressure rod 51 continues to be pulled out outwards driven by the driving member 524. When the pressure rod 51 is completely pulled out of the cloth pushing and spreading device 1, the force storage structure 525 drives the connecting rod 522 to continue to rotate in the direction away from the filter cylinder 2, so that the pressure rod 51 is raised to the initial position. Therefore, it is possible to prevent the end of the filter cloth 71 close to the cloth pushing and spreading device 1 from being lifted too high when the pressure rod 51 moves to the second position. The pressure rod 51 lifts the end of the filter cloth 71 close to the cloth pushing and spreading device 1 to abut against the bottom of the cloth pushing and spreading device 1, thereby ensuring the flatness of the material on the filter cloth 71. At the same time, the efficiency of cloth pushing and spreading can be improved.

[0120] In this embodiment, before the cloth pushing head 113 of the cloth pushing and spreading device 1 moves to the first side edge, the pressing rod 51 can be completely pulled out from both sides of the cloth pushing and spreading device 1 .

[0121] Preferably, the moving speed of the paving body 11 retreating is greater than or equal to the moving speed of the paving body 11 advancing.

[0122] Embodiment 2

[0123] like Figures 1 to 3 ,and Figures 14 to 17 As shown, in the embodiment of the present invention, a cloth pushing and spreading device 1 of the dewatering equipment for interlayer stacked spreading materials in the above-mentioned embodiment 1 is further introduced.

[0124] The cloth-pushing and spreading device 1 comprises a spreading body 11, and a spreading opening 1121 is arranged at the bottom of the spreading body 11. A cloth-pushing head 113 extending downwardly in an inclined manner is arranged at the front end of the spreading body 11 along the feeding direction, and the first end of the cloth-pushing head 113 is connected to the spreading body 11, and the second end of the cloth-pushing head 113 opposite to the first end of the cloth-pushing head 113 is lower than the spreading opening 1121 at least when the cloth-pushing head 113 abuts against the filter cloth 71. During the cloth-pushing and spreading process, the cloth-pushing head 113 at the front end of the spreading body 11 supports the filter cloth 71, and the filter cloth 71 is wrapped around the front end of the spreading body 11, and during the forward feeding process of the spreading body 11, the filter cloth 71 slides along the front end of the spreading body 11, so that the filter cloth 71 is dragged out from the cloth-winding roller 7, and the filter cloth 71 below the spreading body 11 is stretched flat by the reaction force, and the material is spread on the filter cloth 71 below the spreading body 11. The height difference between the second end of the cloth pushing head 113 and the paving opening 1121 can leave space for laying materials between the filter cloth 71 below the paving body 11 and the paving opening 1121, thereby preventing the materials from sticking to the paving body 11 and improving the paving effect of the sludge.

[0125] Preferably, when the cloth pushing head 113 abuts against the filter cloth 71 , the height difference between the second end of the cloth pushing head 113 and the material laying opening 1121 is greater than the thickness of the material laid on the filter cloth 71 .

[0126] A notch 1135 corresponding to the cloth pressing rod 622 is provided in the middle of the second end of the cloth pushing head 113. The notch 1135 penetrates the cloth pushing head 113 along the vertical direction perpendicular to the first end to the second end of the cloth pushing head 113, and the opening of the notch 1135 faces the direction away from the first end of the cloth pushing head 113. In the horizontal direction perpendicular to the first end to the second end of the cloth pushing head 113, the width of the cloth pressing rod 622 is smaller than the width of the notch 1135. When the second end of the cloth pushing head 113 moves to the top of the second side, the notch 1135 moves to the bottom of the cloth pressing rod 622, the movable part 62 rotates to the first position, and the end of the cloth pressing rod 622 away from the rotating shaft 621 passes through the notch 1135 from top to bottom, pressing the filter cloth 71 wrapped on the second end of the cloth pushing head 113 onto the filter cylinder 2.

[0127] Preferably, when the cloth pushing head 113 contacts the filter cloth 71, in the direction from the first end to the second end of the cloth pushing head 113, at least the top of the cloth pushing head 113 is set as a downwardly inclined plane. In the process of the cloth pressing rod 622 pressing the cloth, the inclined surface at the top of the cloth pushing head 113 can be used to unload the force, so that the filter cloth 71 slides downward along the downwardly inclined plane at the top of the cloth pushing head 113 under the force of the cloth pressing rod 622, which can reduce the shear force on the filter cloth 71 and avoid tearing the filter cloth 71.

[0128] Preferably, the cloth pushing head 113 is tilted downward from the first end to the second end of the cloth pushing head 113, and the thickness of the cloth pushing head 113 in the direction perpendicular to the first end to the second end gradually decreases. Thus, the end of the cloth pressing rod 622 can smoothly pass through the notch 1135 to press the filter cloth 71 against the filter cylinder 2. At the same time, the cloth pushing head 113 of the material spreading body 11 is used to push the filter cloth 71 forward to pull the filter cloth 71 out of the cloth winding roller 7, which is conducive to reducing the resistance of the cloth pushing head 113 to the filter cloth 71, and at the same time, it can avoid the filter cloth 71 from having too much excess at the second side of the filter cylinder 2.

[0129] Preferably, the second end of the cloth pushing head 113 is configured to be arc-shaped.

[0130] Preferably, the second end of the cloth pushing head 113 is a solid cylinder 1134 having a diameter smaller than the thickness of the front end of the material paving body 11, and the solid cylinder 1134 is connected to the material paving body 11 through a support plate extending downwardly from the front end of the material paving body 11, and the end of the support plate away from the solid cylinder 1134 is the first end of the cloth pushing head 113. The solid cylinder 1134 is arranged in front of the material paving body 11, spaced apart from the material paving body 11, and connected to the front end of the material paving body 11 through the support plate. The solid cylinder 1134 constitutes the second end of the cloth pushing head 113.

[0131] Preferably, the diameter of the solid cylinder 1134 is smaller than the thickness of the front end of the material laying body 11; the support plates include two, which extend obliquely from the outer peripheral wall of the solid cylinder 1134 to the upper and lower edges of the front end of the material laying body 11, and the end of the support plate away from the solid body constitutes the first end of the cloth pushing head 113. One end of the support plate is connected to the solid cylinder 1134 as a whole, and the other end is connected to the front end of the material laying body 11. The end of the support plate is smoothly connected to the outer peripheral wall of the solid cylinder 1134, so that the second end of the cloth pushing head 113 forms a smooth surface to avoid scratching the filter cloth 71 during the cloth pushing process. Preferably, the two support plates are tangent to the upper and lower sides of the solid cylinder 1134, respectively.

[0132] Preferably, a reinforcing plate 1133 is provided between the two supporting plates to reinforce the structure of the cloth pushing head 113 .

[0133] like Figures 14 to 17 As shown, in some specific embodiments, the extension length of the support plate connected to the solid column 1134 from the bottom of the solid column 1134 is smaller than the extension length of the support plate connected to the solid column 1134 from the top of the solid column 1134, and the reinforcing plate 1133 is arranged between one end of the support plate connected to the solid column 1134 from the bottom of the solid column 1134 away from the solid column 1134 and the middle part of the support plate connected to the solid column 1134 from the top of the solid column 1134.

[0134] In this embodiment, the cloth pushing head 113 and the material spreading body 11 can be connected as one body, or can be set to rotate with each other. Preferably, at least one end of the support plate connected to the solid cylinder 1134 from the top of the solid cylinder 1134 away from the solid cylinder 1134 is smoothly connected to the material spreading body 11.

[0135] In some possible embodiments, the cloth pushing head 113 is connected as a whole with the material spreading body 11. Specifically, one end of the two support plates of the cloth pushing head 113 away from the solid cylinder 1134 is respectively connected to the upper and lower edges of the front end of the material spreading body 11, and the second end of the cloth pushing head 113 is lower than the material spreading opening 1121.

[0136] In this embodiment, in order to prevent the cloth-pushing head 113 from scraping the material under the material-paving body 11, when the material-paving body 11 retreats, the material-paving body 11 can be controlled to rise, or the cloth-pushing and material-paving device can be controlled to rise as a whole, or the movable bottom plate of the filter cylinder can be controlled to move downward, so that the cloth-pushing head 113 can avoid the material laid on the filter cloth. Specifically, the filter cylinder includes a cylinder body and a movable bottom plate located in the cylinder body, and the cylinder body is a hollow cubic structure with water outlets on the sides; the top of the cylinder body is open, the movable bottom plate matches the cross-section of the inner cavity of the cylinder body and can move up and down along the cylinder body, and the bottom of the cylinder body is open. Preferably, the movable bottom plate 22 initially moves to a position slightly lower than the top of the filter cylinder 2, and the interval between the movable bottom plate 22 and the top of the filter cylinder 2 is greater than or equal to the thickness of the material laid on the filter cloth 71; when the front end of the cloth-pushing and material-paving device 1 moves to the outside of the first side along the feeding direction, the movable bottom plate 22 of the filter cylinder 2 moves downward by a stroke, which matches the sum of the thickness of the material laid on the filter cloth 71 and the thickness of the filter cloth 71.

[0137] like Fig.16 and Fig.17 As shown, in some other possible embodiments, the cloth pushing head 113 is rotatably matched with the material laying body 11. Thus, when the material laying body 11 is fed forward, the cloth pushing head 113 can be controlled to rotate downward, so that the second end of the cloth pushing head 113 is lower than the material laying opening 1121, and a height difference greater than the thickness of the material laid on the filter cloth is formed between the cloth pushing head 113 and the material laying opening 1121. When the material laying body 11 is retracted, the cloth pushing head 113 can be controlled to rotate upward, so that the second end of the cloth pushing head 113 is higher than the material on the filter cloth 71, which can prevent the cloth pushing head 113 from scraping the material under the material laying body 11 and preventing the material from sticking to the cloth pushing head 113, thereby improving the material paving effect. At the same time, it is beneficial to increase the retraction speed of the material laying body 11 and the material laying rate.

[0138] Preferably, the cloth-pushing head 113 includes a first position that rotates upward to an upper limit, and a second position that rotates downward to a lower limit. When the cloth-pushing head 113 is in the first position and the second position, the height difference of the second end of the cloth-pushing head 113 is greater than the thickness of the material laid on the filter cloth. Preferably, an elastic member is provided between the cloth-pushing head 113 and the material-laying body 11, and the elastic member is used to drive the cloth-pushing head 113 to rotate toward the first position. During the forward feeding of the material-laying body 11, the reaction force applied by the filter cloth 71 to the cloth-pushing head 113 is greater than the elastic force of the elastic member. The cloth-pushing head 113 rotates toward the second position under the drive of the reaction force of the filter cloth 71. Thus, the cloth-pushing head 113 can be automatically switched between the first position and the second position, and can match the cloth-pushing and material-laying action of the material-laying body 11. Specifically, in this embodiment, when the cloth pushing head 113 rotates to the first position, the height of the axis of the solid cylinder 1134 is lower than the height of the rotation center of the cloth pushing head 113, thereby ensuring that the cloth pushing head 113 can rotate smoothly to the second position under the reaction force of the filter cloth 71.

[0139] like Fig.16 and Fig.17 As shown, in some specific embodiments, the front end surface of the material laying body 11 can be used to limit the rotation of the cloth pushing head 113. Specifically, the rotating shaft can be set between the middle of the front end surface of the material laying body 11 and the cloth pushing head 113, and a gap for the cloth pushing head 113 to rotate is set between the cloth pushing head 113 and the material laying body 11. When the cloth pushing head 113 rotates to the first position, the upper end of the cloth pushing head 113 close to the material laying body 11 abuts against the front end of the material laying body 11, and when the cloth pushing head 113 rotates to the second position, the lower end of the cloth pushing head 113 close to the material laying body 11 abuts against the front end of the material laying body 11. The elastic member used to drive the cloth pushing head 113 to rotate to the first position can be a torsion spring.

[0140] Preferably, the upper edge of the front end of the material spreading body 11 and / or the upper edge of the first end of the cloth pushing head is provided with an arc chamfer to avoid scratching the filter cloth.

[0141] Preferably, the top of the working end of the first cloth pressing assembly 5 is substantially flush with the bottom of the second end of the cloth pushing head 113 .

[0142] Specifically, when the working end of the first cloth pressing assembly 5 presses the filter cloth 71 on the first side of the filter cylinder 2 onto the filter cylinder 2, the top of the working end of the first cloth pressing assembly 5 is slightly lower than the bottom of the second end of the cloth pushing head 113, allowing the cloth pushing head 113 to pass smoothly.

[0143] Preferably, the height difference between the bottom of the second end of the cloth pushing head 113 and the top of the working end of the first cloth pressing assembly 5 is greater than or equal to the thickness of the filter cloth 71 .

[0144] Preferably, the material spreading opening 1121 is arranged at the bottom of the material spreading body 11 and close to the front end of the material spreading body 11, that is, the material spreading opening 1121 is arranged close to the cloth pushing head 113, so that the material can be spread all over the filter cloth 71 below.

[0145] Preferably, the cloth pushing and spreading device 1 is a double-layer structure, including a base 12 and a spreading body 11 installed on the base 12 .

[0146] The base 12 is mounted on the frame 4 through the first guide assembly 54, and the material-laying body 11 is mounted on the base 12 through the second guide assembly 54. One end of the driving device is connected to the base 12, and the other end is connected to the material-laying body 11. Therefore, before pushing and paving the material, the base 12 can be driven by the front driving device between the base 12 and the frame 4 to carry the material-laying body 11 and move along the first guide assembly 54 to approach the filter cylinder 2. In the process of pushing and paving the material, the driving device only needs to drive the material-laying body 11 to reciprocate above the filter cylinder 2. The elongated length of the driving device is maintained in a relatively small range, which is conducive to ensuring the smoothness of the reciprocating motion of the material-laying body 11, and can improve the efficiency and control accuracy of pushing and paving the material. At the same time, the driving device with a small stroke can realize the driving of the material-laying body 11, which is conducive to reducing the cost of the equipment.

[0147] The first guide assembly 54 and the second guide assembly 54 may be a sliding guide rail structure or a rolling guide rail structure.

[0148] The extension direction of the first guide assembly 54 is parallel to the extension direction of the second guide assembly 54. During the movement of the base 12 along the first guide assembly 54, the front end of the cloth pushing body of the cloth pushing and spreading device 1 and the first side of the filter cylinder 2 are close to each other and always remain aligned.

[0149] The driving device and the front driving device can be any one of a hydraulic cylinder, a pneumatic cylinder, and a linear motor, or a combination of two or more thereof.

[0150] In this embodiment, a material laying pipe 112 is provided inside the material laying body 11, and a material delivery pipe 15 connected to the material laying pipe 112 is provided outside the material laying body 11. The material delivery pipe 15 is connected to the material laying pipe 112 and is used to deliver materials to the material laying body 11. In order to adapt to the reciprocating motion of the material laying body 11, the material delivery pipe 15 is generally set as a hose. By setting the material delivery pipe 15 as a hose, the material delivery pipe 15 can move forward and backward with the base 12 and the material laying body 11, and there is no need to install an additional pipe shaft with a steering function like a hard pipe. The complexity of the device is greatly reduced and the durability is improved.

[0151] Preferably, the material paving body 11 includes a shell 111 and a material paving pipe 112 installed in the shell 111. An opening is provided at the bottom of the shell 111. The material paving pipe 112 is installed in the shell 111. The material paving port 1121 of the material paving pipe 112 is provided in the opening. The material paving body 11 sprays and unloads materials through the material paving port 1121 of the material paving pipe 112.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
