Description

Technical Field

[0001] The present invention relates to the field of pressure equipment, and specifically to a sewage treatment plant sludge treatment system. Background Art

[0002] When a sewage treatment plant is operating, a large amount of sludge with a high water content is generated. To reduce the water content of the sludge so that the sludge is more suitable for resource treatment methods such as composting, incineration, landfilling, land use, and building materials use, pressure equipment is often used to apply pressure to the sludge to squeeze out the water in the sludge.

[0003] The pressure application principle is to fill the sludge into the filter cloth, and then a pressure output device such as a hydraulic press applies pressure to the sludge in the filter cloth, so that the water in the sludge flows out of the filter cloth, and the solids in the sludge are retained in the filter cloth to form a filter cake, thereby realizing solid-liquid separation. After the pressure filtration is completed, the pressure output device such as a hydraulic press rises, and then the filter cake is peeled off from the filter cloth.

[0004] In the above process, if the filter cloth is unfolded, folded, etc. manually, there are problems such as a large amount of labor and low efficiency. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems and provide a sewage treatment plant sludge treatment system that can reduce the labor intensity of workers.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is a sewage treatment plant sludge treatment system: including a box body, a filter cloth, and a sludge conveying pipe. The sludge conveying pipe moves horizontally, the filter cloth is folded vertically, the upper edge of the filter cloth is connected to the upper support plate, the lower edge of the filter cloth is connected to the lower support plate, and access holes are provided on the side walls of the upper support plate and the lower support plate. A take-up and release cylinder is provided at the bending portion of the filter cloth, and the access holes and the take-up and release cylinder are arranged along the width direction of the filter cloth. A working area is provided in the box body, and a cloth feeding mechanism and a pressure filtration mechanism are arranged at intervals horizontally in the working area. The cloth feeding mechanism includes a lifting part that moves vertically and a support group arranged on both sides of the filter cloth. The support group includes a main support part and a secondary support part, and both the main support part and the secondary support part move axially along the take-up and release cylinder. A drain pipe is provided at the bottom of the working area at the position of the pressure filtration mechanism. The pressure filtration mechanism includes a base and a pressing plate arranged opposite to each other up and down. The pressing plate moves vertically, and a pushing part is provided in the working area to push the filter cloth from the cloth feeding mechanism to the pressure filtration mechanism. By unfolding and folding the filter cloth layer by layer and cooperating with the movement of the sludge conveying pipe, the sludge can be automatically fed, thereby reducing the labor intensity of workers and improving work efficiency.

[0007] Furthermore, in order to further reduce manual intervention, a stripping area is provided on one side of the filter press mechanism in the box body, and a stripping mechanism is provided in the stripping area. The stripping mechanism includes a carrier plate that moves vertically and supports arranged on both sides of the width direction of the filter cloth, and transverse driving mechanisms are arranged on the supports at intervals, and the output end of the transverse driving mechanism is connected to the temporary storage part; a conveying path with an open end is provided on the bottom wall of the stripping area of ​​the box body; in order to move the filter cloth on the base to the stripping area, the lower end of the base is arranged on the rotating part, and a traction part for pushing the filter cloth is provided in the box body.

[0008] Furthermore, a beating part which moves along the length direction of the filter cloth is also arranged in the stripping area, and the filter cake is ensured to fall off from the filter cloth through the reciprocating movement of the beating part.

[0009] Furthermore, to facilitate subsequent storage, a sizing portion is provided in the stripping area, and the sizing portion moves along the length direction of the filter cloth under the action of the sizing drive mechanism. The sizing portion moves to flatten the filter cloth to reduce wrinkles and reduce storage space, while also extending the service life of the filter cloth to a certain extent.

[0010] Furthermore, the height of the lateral drive mechanism is independently adjusted to improve adaptability.

[0011] Furthermore, since the filter cloth is a flexible material, in order to prevent the position of the pick-and-place cylinder adjacent to the unfolded filter cloth from moving when the filter cloth is unfolded, resulting in the subsequent temporary storage part being unable to cooperate with the pick-and-place cylinder, etc., a limited drive mechanism is provided on both sides of the width direction of the filter cloth in the stripping area, and the output end of the limited drive mechanism is connected to the limited part, and the limited drive mechanism is adjusted in the vertical direction. The limited part extends into the pick-and-place cylinder adjacent to the unfolded filter cloth layer to prevent it from moving.

[0012] Furthermore, a conveying screw is provided in the conveying channel in the same direction as the conveying channel to bring the peeled filter cake out of the box.

[0013] Furthermore, a support plate in contact with the side wall of the filter cloth is provided at the upper end of the base, and a drainage hole is provided on the support plate. The side wall of the filter cloth is supported by the support plate to ensure the normal operation of the filter press and limit the movement of the sludge.

[0014] Furthermore, the lifting parts are arranged at intervals, and a positioning part is arranged at the upper end of the lifting part.

[0015] Furthermore, the heights of the main supporting portion and the auxiliary supporting portion are adjusted independently to improve adaptability.

[0016] Advantages of the present invention: Through the lifting of the lifting part and the cooperation of the auxiliary support part of the main support part, the filter cloth is unfolded from bottom to top. When the filter cloth is unfolded, the sludge conveying pipe extends between two layers of filter cloths, and then the sludge to be pressed is fed between the two layers of filter cloths. As the sludge conveying pipe withdraws from between the filter cloths, the cloth is evenly distributed, so as to improve the subsequent pressure filtration effect. After the sludge is filled, the filter cloth is refolded to facilitate the subsequent pressure filtration. Thus, on the premise of reducing manual intervention, the cloth distribution of the sludge and the unfolding and folding of the filter cloth are completed, so as to reduce the labor intensity of the staff.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0025] Example 1, as Figures 1 - 4 shown Figure 1The dotted line in the figure shows the position of the filter cloth. The specific structure of this embodiment is as follows: it includes a box body 1, a filter cloth 2 and a mud conveying pipe 3. The filter cloth 2 is folded vertically, and the folded filter cloth is in a Z shape. The upper edge of the filter cloth 2 is connected to the upper support plate 4, and the lower edge of the filter cloth 2 is connected to the lower support plate 5. The connection between the filter cloth 2 and the upper and lower support plates is on the same side. In this embodiment, the connection between the filter cloth 2 and the upper and lower support plates is located at Figure 2 The upper and lower support plates are made of hard materials such as stainless steel. The edges of the filter cloth do not exceed the outer side walls of the upper and lower support plates. The upper support plate 4 and the lower support plate 5 are provided with access holes 6 on their side walls. The filter cloth 2 is provided with access cylinders 7 at its bend. The access cylinders 7 are arranged at the four corners of the filter cloth. The access holes 6 and access cylinders 7 are arranged along the width direction of the filter cloth 2. The positions of the two adjacent access cylinders 7 on the same side are staggered. The mud delivery pipe 3 is located on the right side of the filter cloth 2 when working. The mud delivery pipe 3 moves horizontally under the action of the linear drive mechanism of the hydraulic cylinder. The mud delivery pipe 3 is connected to the sludge storage through a connecting pipe. A valve is provided on the mud delivery pipe 3 to control the output of the sludge.

[0026] The box body 1 is provided with a working area, in which a material distribution mechanism and a filter pressing mechanism are arranged at intervals along the lateral direction. A guide rail 29 connecting the material distribution mechanism and the filter pressing mechanism is provided on the bottom wall of the box body 1 .

[0027] The cloth mechanism includes a lifting part 8 that moves vertically and a support group arranged on both sides of the filter cloth. The lifting part 8 can be driven by a hydraulic cylinder buried in the box body 1, or a vertical groove can be arranged on the side wall of the box body 1. The extension part at the side end of the lifting part 8 extends into the vertical groove. The vertical groove is provided with a guide column and a vertical screw rod that cooperate with the extension part. The vertical screw rod is connected to the vertical motor by transmission. In this embodiment, the lifting part 8 is provided with two pieces and is placed on both sides of the length direction of the guide rail 29. When the lifting part 8 moves to the bottom, the upper end surface of the guide rail 29 is not lower than the upper end surface of the lifting part 8. The upper end surface of the lifting part 8 is provided with a positioning part 28, and the filter cloth is placed between the two positioning parts 28 to ensure that the position of the filter cloth remains uniform during filtration.

[0028] The support group includes a main support portion 9 and a secondary support portion 10. Both the main support portion 9 and the secondary support portion 10 move axially along the pick-up and placement cylinder 7. For this purpose, the main support portion 9 and the secondary support portion 10 are respectively driven by independent support portion drive mechanisms, and at the same time, the support portion drive mechanisms are installed on the output end of the support vertical adjustment mechanism. The number of support vertical adjustment mechanisms matches that of the support portion drive mechanisms. The support vertical adjustment mechanism is installed in the box body 1. The support vertical adjustment mechanism and the support portion drive mechanism can adopt hydraulic cylinders, electric push rods, etc.; a groove is provided at the bottom of the working area at the pressure filtration mechanism, and a drain pipe 11 is provided at the bottom of the groove. The pressure filtration mechanism includes a base 12 and a pressing plate 13 which are arranged oppositely up and down. The pressing plate 13 moves vertically under the drive of an oil cylinder or the like. A pushing portion 14 for pushing the filter cloth to move from the cloth feeding mechanism to the pressure filtration mechanism is provided in the working area, and the pushing portion 14 can be pushed by an oil cylinder or the like.

[0029] A support plate 27 in contact with the side wall of the filter cloth 2 is provided at the upper end of the base 12. There are three support plates 27. In this way, when the pushing portion 14 moves to the pressure filtration mechanism, the support plate 27 and the pushing portion 14 can enclose all the side walls of the filter cloth. Drainage holes are provided on the support plate 27.

[0030] Specific working process: The lifting portion 8 rises to the highest point, and the staff places the filter cloth 2 in the folded state on the lifting portion 8. The main support portion 9 and the secondary support portion 10 respectively extend into the pick-up and placement cylinders 7 on the left and right sides of the third layer of filter cloth from bottom to top. When the lifting portion 8 descends, the two bottom layers of filter cloth are unfolded, and the bending points of these two layers of filter cloth are located at Figure 2 the left side. After the filter cloth 2 is unfolded, the sludge delivery pipe 3 extends between the two layers of filter cloth 2. To ensure the unfolding of the filter cloth, a laterally extending ejector rod 30 is provided on the side of the filter cloth 2 for the sludge delivery pipe 3. The ejector rod 30 abuts against the filter cloth 2. Here, a sensing unit such as a proximity switch can be provided on the ejector rod 30 to automatically sense the moving position of the ejector rod 30. The ejector rod 30 abuts against the inner wall of the filter cloth 2, so that the filter cloth 2 is unfolded as much as possible, and at the same time, the moving position of the sludge delivery pipe 3 is restricted, so that the filled sludge is within the working range of the pressing plate 13. After the ejector rod 30 abuts against the inner wall of the filter cloth 2, the sludge delivery pipe 3 delivers the sludge between the two unfolded layers of filter cloth and at the same time the sludge delivery pipe 3 returns to the distal end of the filter cloth 2. When the outlet of the sludge delivery pipe 3 moves to the midline of the filter cloth 2, the sludge delivery pipe 3 can be closed. At this time, through the movement of the slurry-like sludge, the sludge is flattened as much as possible, and a certain space is left between the sludge and the edge of the filter cloth 2 to prevent the sludge from falling out of the filter cloth 2 during pressure filtration.

[0031] After the mud conveying pipe 3 exits the filter cloth 2, the lifting part 8 rises again to refold the filter cloth 2, and then the lifting part 8 carries the filter cloth and descends to a certain height, so that the main support part 9 and the auxiliary support part 10 extend into the take-in and put-out cylinders 7 on the left and right sides of the fifth layer of filter cloth from bottom to top, respectively. After the main support part 9 and the auxiliary support part 10 fix the filter cloth, the lifting part 8 descends, and the gravity of the sludge and the slurry sludge adhere to the sludge, so that the filled filter cloth will not unfold, but the third and fourth layers of filter cloth from bottom to top unfold, and then the sludge is refilled. This is carried out in sequence until the sludge is spread.

[0032] After the cloth is finished, the lifting part 8 drops to the lowest point, and the pushing part 14 pushes the upper and lower supporting plates to move the filter cloth to the base 12, and then the pressing plate 13 drops to apply pressure to the filter cloth 2, and the sewage flows out from the filter cloth 2 and is discharged from the drain pipe 11. After the filtration, the pushing part 14 is reset, and the staff takes out the filter cloth 2.

[0033] Multiple filter cloths can be prepared to perform filtration and cloth cleaning at the same time to improve work efficiency.

[0034] Embodiment 2, as Figure 1 , Figure 5 , Figure 6 As shown, the other structures and working processes of this embodiment are the same as those of embodiment 1, but in this embodiment, the lower end of the base 12 is arranged on the rotating part 15, and the rotating part 15 can be driven by hydraulic pressure, motor, etc., and a lifting mechanism is also arranged in the box body 1 to support the base 12 from below when the pressing plate 13 is working, so as to prevent the rotating part 15 from being subjected to pressure. The box body 1 is provided with a traction part 31 for pushing the filter cloth from the working area to the stripping area, and the moving path of the traction part 31 is staggered with the supporting plate 27, and the traction part 31 can be driven by a linear driving mechanism such as a hydraulic cylinder.

[0035] The stripping area is arranged on one side of the filter press mechanism, and a stripping mechanism is arranged in the stripping area. The stripping mechanism includes a carrier plate 16 that moves vertically and a support 17 arranged on both sides of the filter cloth width direction. A vertical driving mechanism 32 is arranged on the support. The piston rod of the vertical driving mechanism 32 is connected to the cylinder body of the horizontal driving mechanism 18. The height of the temporary storage part 19 is adjusted by the vertical driving mechanism 32 to ensure that the temporary storage part 19 can be connected to the pick-up and release cylinder 7. Four vertical driving mechanisms 32 are arranged, which correspond to the pick-up and release cylinders 7 at the angle of the filter plate respectively, and the output end of the horizontal driving mechanism 18 is connected to the temporary storage part 19; the box body 1 is provided with a conveying path 20 with one end open on the bottom wall of the stripping area, and the open end of the conveying path 20 is located at the far end of the working area. A conveying screw 26 in the same direction as it is arranged in the conveying path 20.

[0036] A flapping part 21 that moves along the length direction of the filter cloth 2 is further arranged in the stripping area. In this embodiment, a flapping driving mechanism is arranged on the partition plate between the stripping area and the working area, and the piston rod of the flapping driving mechanism is connected to the flapping part 21.

[0037] A sorting part 22 is arranged in the stripping area, and the sorting part 22 moves along the length direction of the filter cloth 2 under the action of a sorting driving mechanism 23.

[0038] Limit driving mechanisms 24 are arranged on both sides of the filter cloth 2 in the width direction in the stripping area. The output end of the limit driving mechanism 24 is connected to a limiting part 25. The limit driving mechanism 24 adjusts its position vertically. For this purpose, the limit driving mechanism 24 can be arranged in a long strip groove on the side wall of the box body 1 and moves under the drive of an electric push rod, a linear module, etc. The transverse driving mechanism 18, the flapping driving mechanism, the vertical driving mechanism 32, the limit driving mechanism 24 and the sorting driving mechanism 23 can adopt hydraulic cylinders, electric push rods, etc.

[0039] Specific working process: After the pressure filtration is completed at the pressure filtration mechanism, the pushing part 14 retracts and resets, and the base 12 rotates so that the open surface of the space enclosed by the support plates 27 faces the stripping area. Then, the traction part 31 pushes the upper and lower support plates to move the filter cloth to the upper end of the loading plate 16. After the filter cloth 2 moves to the upper end of the loading plate 16, the traction part 31 resets, and then the loading plate 16 rises so that the upper support plate 4 moves between the supports 17. Subsequently, the temporary storage part moves towards the filter cloth 2 side to extend into the picking and placing hole 6. After the temporary storage part fixes the upper support plate 4, the loading plate descends. At the same time, the limiting part 25 extends into the picking and placing cylinders 7 on both sides of the third layer of filter cloth from top to bottom, so that the first and second layers of filter cloths open, and the opening side is at the far end of the working area. In this way, the filter cakes in the first and second layers of filter cloths fall downward. To ensure that the filter cakes do not adhere to the filter cloth, after the filter cloths open, the flapping part moves back and forth to beat the filter cloth to peel the filter cakes from the filter cloth. At the same time, the limiting part 25 fixes the third layer of filter cloth, which can prevent the third layer of filter cloth and the subsequent filter cloths from shifting, resulting in the subsequent temporary storage part 19 being unable to be connected to the picking and placing cylinder 7. Of course, a transverse adjustment mechanism can also be arranged on the support to adjust the transverse position of the temporary storage part 19. Visual sensors can be arranged on the supports 17, the inner side of the box body 1, etc. to detect the position of the picking and placing cylinder 7.

[0040] After the filter cakes between the first and second layers of filter cloths are peeled off, the loading plate 16 and the limit driving mechanism 24 rise, so that the first and second layers of filter cloths return to the folded state. After the first and second layers of filter cloths are folded, the sorting part extends into the gap between the first and second layers of filter cloths and moves towards the bending part of the first and second layers of filter cloths to reduce the wrinkles on the filter cloth and make the filter cloth as flat as possible.

[0041] Subsequently, the sorting unit 22, the limiting unit 25, and the temporary storage unit 19 are reset, and the carrier plate 16 continues to rise so that the third-layer filter cloth moves between the temporary storage units 19. Subsequently, the temporary storage unit 19 extends into the pick-up cylinders 7 on both sides of the third-layer filter cloth. Then, the carrier plate 16 descends, and the limiting unit 25 extends into the pick-up cylinders 7 on both sides of the fifth-layer filter cloth to open the third and fourth-layer filter cloths to restart the peeling of the filter cake until all the filter cakes between the filter cloths are peeled off. The peeled filter cakes are transported out of the box body 1 through the conveying channel 20, and the filter cloths are taken out from the opening at the upper end of the box body 1.
