Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, in particular to a device for separating a cloth used for covering sludge and the sludge. Background Art

[0002] In the sludge treatment system, the function of the spreader is to separate the roll cloth from the sludge after the sludge is subjected to heavy pressure treatment. The separated sludge falls out through the spreader and is then transported and discharged by the auger. The spreader can be set on different and opposite sides of the conveyor's moving path to achieve efficient and compact sludge treatment process.

[0003] The applicant's prior invention patent CN114292004B discloses a sludge treatment system and a sludge treatment method, and specifically relates to a sludge feeder, including a frame, a spreading shaft, a spreading motor, a rolling shaft, and a rolling motor. The spreading shaft and the rolling shaft are sequentially arranged on the frame along the cloth conveying direction. Both ends of the spreading shaft are fixed on the frame. The spreading shaft is divided into an upper spreading shaft for spreading the upper layer of cloth and a lower spreading shaft for spreading the lower layer of cloth. The upper spreading shaft is located above the lower spreading shaft. The spreading motor is The rotating shaft is connected to the upper cloth-unrolling shaft and the lower cloth-unrolling shaft respectively through chains; the cloth-rolling shaft is mainly composed of an upper cloth-rolling shaft and a lower cloth-rolling shaft with two ends fixed on the frame, the upper cloth-rolling shaft is located above the lower cloth-rolling shaft, and the cloth-rolling motor includes an upper cloth-rolling motor and a lower cloth-rolling motor fixed on the frame, and the upper cloth-rolling motor drives the upper cloth-rolling shaft to rotate, and the lower cloth-rolling motor drives the lower cloth-rolling shaft to rotate, the upper layer of cloth of the upper and lower layers of cloth covering the sludge contacts and is wound on the lower side of the upper cloth-rolling shaft, and the lower layer of cloth contacts and is wound on the upper side of the lower cloth-rolling shaft.

[0004] In this application, the cloth conveying direction is from the first side to the second side. This application sets a lower deviation correction shaft between the lower cloth spreading shaft and the lower cloth winding shaft, and the cloth that goes around the lower deviation correction shaft directly enters the lower cloth winding shaft. The lower deviation correction shaft can only be set on the first side of the cloth covering the sludge to achieve the purpose of deviation correction. In this technology, the support seat for installing the lower cloth winding shaft arranged on the frame has an opening for facilitating the installation and disassembly of the cloth winding shaft, and the cloth winding shaft can be quickly installed in or removed from the support seat, so as to install or remove the cloth winding shaft on the frame. In the above technology, when the lower cloth winding shaft is rolling the cloth, the reverse pulling force of the support seat is applied to the cloth winding shaft from the second side to the first side ( Figure 2 The middle dotted line indicates the improved way in which the cloth is rolled into the lower cloth rolling shaft), that is, the opposite direction of the cloth rolling transmission direction. Therefore, the opening of the above-mentioned support seat is arranged on the second side, so that the reverse pulling force applied by the cloth rolling is offset by the supporting force provided by the closed part of the first side of the support seat. The opening does not need to be closed, and the lower cloth rolling shaft will not be separated from the support seat from the opening when the cloth is rolled, which is convenient for installing or removing the cloth rolling shaft.

[0005] However, in engineering practice, it is found that in the solution of the above patent document where the cloth wound out of the lower deviation rectifying shaft directly enters the lower cloth winding shaft, for the already dewatered sludge, some types of sludge are prone to firmly adhere to the front side of the cloth covering the sludge, making it difficult to achieve a satisfactory sludge detachment effect under some working conditions in the above solution, seriously affecting the cloth winding efficiency and the reuse of the wound cloth.

[0006] The inventor accidentally found that adding a roller between the deviation rectifying shaft and the cloth winding shaft in the present invention, and the roller winds in from the back side of the cloth covering the sludge and acts on the back side and the sludge adhered to the front side of the cloth through the action of the roller, can greatly improve the detachment effect of the sludge firmly adhered to the front side of the cloth covering the sludge. However, the above improvement will cause the direction of the cloth winding into the lower cloth winding machine to be redirected, and the reverse pulling force exerted by the cloth winding on the support seat when the lower cloth winding shaft winds the cloth changes from the original second side to the first side, that is, the reverse direction of the cloth transmission direction is redirected from the first side to the second side ( Figure 2 The solid line in [reference] indicates the way the cloth enters the lower cloth winding shaft after the improvement), that is, the cloth transmission direction. The above redirection causes the above open - mouth method on the support seat, and when the cloth winding starts or stops, due to the fluctuation of the pulling force, it is easy to cause the lower cloth winding shaft to vibrate, and the deviation rectifying effect of the deviation rectifying shaft is significantly affected. Even when winding the cloth, it may cause the lower cloth winding shaft to break away from the open - mouth, affecting the cloth - sludge separation effect and efficiency.

[0007] In engineering practice, when the defects caused by the above improvement cannot be overcome, the improvement solution of adding a roller between the deviation rectifying shaft and the cloth winding shaft in the present invention cannot be directly implemented. Although adding a roller between the deviation rectifying shaft and the cloth winding shaft has obvious effects, not all types of sludge necessarily adapt to this means and can also have a satisfactory sludge removal effect. In particular, for the solution of the present application, it is not necessarily applicable to all types of sludge. There is a need for alternating or replacing the use of the solution in the above patent document where the cloth wound out of the lower deviation rectifying shaft directly enters the lower cloth winding shaft and the solution of adding a roller between the deviation rectifying shaft and the cloth winding shaft in the present invention. This leads to the fact that in order to reduce the influence of the open - mouth, usually only a non - detachable and non - installable closed support seat can be made. Otherwise, it is difficult to achieve frequent disassembly of the fixed support seat for large - scale mechanical equipment. However, a non - detachable and non - installable closed support seat will seriously affect the convenience and efficiency of shaft replacement. Utility Model Content

[0050] As Figure 1 and 3 shown, wherein, the spreading shaft 300 is installed on the frame body 100 and includes an upper spreading shaft 310 and a lower spreading shaft 320. The lower cloth winding shaft 420 is inserted into its corresponding support base 200 from the first opening 212.

In the solution of the spreading shaft 300, preferably, the upper cloth winding shaft 410 is inserted into its corresponding support base 200 from the first opening 212. Among them, for the support base 200 where the upper cloth winding shaft 410 is installed, a switch control device 700 for controlling the first opening 212 to be open or closed is provided on the first opening 212 on the second side thereof.

[0051] As Figure 3As shown, in the solution of the switch control device 700, the support base 200 for mounting the lower fabric winding shaft 420 has a switch control device 700 at the first opening 212 on the second side thereof, which can control the first opening 212 to be open or closed. Preferably, the support base 200 for mounting the upper fabric winding shaft 410 has a switch control device 700 at the first opening 212 on the second side thereof, which can control the first opening 212 to be open or closed.

[0052] As Figure 3As shown, in the solution of the switch control device 700, the switch control device 700 includes a gland 710, a positioning member 720, a rotating shaft member 730, a connecting member 740, and an arc-shaped slider 750. The gland 710 includes a first shaft 711, a fixing portion 712, and an arc portion 713. The first shaft 711 is disposed on the first side of the bearing seat 210. The fixing portion 712 is disposed between the two vertical plates 211 of the bearing seat 210. The first shaft 711 penetrates through the two vertical plates 211 and the fixing portion 712 between the vertical plates 211, so that the fixing portion 712 is rotatably connected between the vertical plates 211. The arc portion 713 is formed into an outwardly convex arc. The upper arc end of the arc portion 713 is connected to the fixing portion 712. The lower arc end of the arc portion 713 is disposed between the two vertical plates 211 and on the second side of the bearing seat 210. The positioning member 720 is connected to the lower arc end of the arc portion 713, and an arc groove 721 is provided on the positioning member 720. The rotating shaft member 730 is fixed on the panel on which the bearing seat 210 is installed and includes a rotating shaft that rotates in a horizontal plane. One end of the connecting member 740 is connected to the rotating shaft of the rotating shaft member 730. The arc-shaped slider 750 is connected to the other end of the connecting member 740 and cooperates with the arc groove 721 of the positioning member 720, and is assembled or separated from the arc groove 721 driven by the rotation of the rotating shaft of the rotating shaft member 730, so as to limit or release the lower arc end of the arc portion 713 of the gland 710. It can be understood that the arc groove 721 is adapted to the arc-shaped slider 750, and in the arc sliding direction of the arc-shaped slider 750, the arc groove 721 is formed into an opening on the corresponding side. Preferably, the connecting member 740 is a rod. Preferably, the bottom plate of the bearing seat 210 is provided with bolt holes for cooperating with bolts and nuts for installation. Preferably, the support seats 200 are provided in pairs on opposite sides. The structure of the gland of the present utility model and its cooperation and installation with the support seat make the structure compact. Moreover, the rotating shaft member provides rotation in the horizontal plane, thereby driving the connecting member to form an arc trajectory in the horizontal plane, so that the arc-shaped slider and the arc groove of the cooperating member cooperate. On the one hand, the influence of unidirectional vibration on the closing of the gland is smaller, and the fixing reliability of the gland is higher. The present utility model provides a switch control device that can control the opening or closing of the open port on the second side of the support seat for installing the lower cloth winding shaft, so that no matter what the orientation of the open port of the support seat is, even if affected by the reverse pulling force of the winding cloth, the cloth winding shaft will not be separated from the open port, thereby further avoiding the influence on the winding of the cloth. Moreover, when installing or disassembling the cloth winding shaft, the open port can be controllably opened, and the open port function can still be realized.In particular, the structure of the gland of the present invention, its cooperation and installation with the support seat make the structure compact. Moreover, the rotation shaft component provides rotation in the horizontal plane, thereby driving the connecting piece to form an arc-shaped trajectory in the horizontal plane, enabling the arc-shaped slider and the arc-shaped groove of the cooperating piece to cooperate. On the one hand, the influence of unidirectional vibration on the closing of the gland is smaller, and the fixing reliability of the gland is higher.

[0053] As Figures 1-2 shown, wherein, the upper guide roller 500 is arranged between the upper spreading shaft 310 and the upper winding shaft 410, and the setting position is lower than the upper winding shaft 410 and lower than the position of the upper layer of fabric on the first side from the upper guide roller 500, and is arranged below the first side of the upper winding shaft 410. Among them, the upper layer of fabric unfolded by the upper spreading shaft 310 enters the upper guide roller 500 from the first side below the lower part of the upper guide roller 500 with the second surface 1020, and exits the upper guide roller 500 from the second side below the lower part of the upper guide roller 500. It enters and winds around the upper winding shaft 410 from the second side above the upper part of the upper winding shaft 410 with the second surface 1020.

[0054] As Figures 1-2 shown, wherein, the lower guide roller 600 is arranged between the lower spreading shaft 320 and the lower winding shaft 420, and the setting position is higher than the lower winding shaft 420 and higher than the position of the lower layer of fabric on the first side from the lower guide roller 600, and is arranged above the second side of the lower winding shaft 420. Among them, the lower layer of fabric unfolded by the lower spreading shaft 320 enters the lower guide roller 600 from the first side above the upper part of the lower guide roller 600 with the second surface 1020, and exits the lower guide roller 600 from the second side above the upper part of the lower guide roller 600. It enters and winds around the lower winding shaft 420 from the second side below the lower part of the lower winding shaft 420 with the second surface 1020.

[0055] In engineering practice, the inventor found that in the patent document CN114292004B of the background technology, the solution that the fabric wound out from the lower deviation correction shaft 820 directly enters the lower winding shaft 420. For the dried sludge, some types of sludge are prone to form a firm bond with the front side of the fabric covering the sludge, making it difficult to achieve a satisfactory sludge detachment effect in some working conditions of the above solution, seriously affecting the winding efficiency and the recycling use of the winding.

[0056] The inventor accidentally discovered that adding a roller between the deviation rectifying shaft 1000 and the cloth winding shaft 400 in the above-mentioned utility model, and the roller winds into and passes through the back of the cloth coated with sludge, and acts on the back and the sludge adhered to the front of the cloth, can greatly improve the detachment effect of the stable adhesion on the surface of the cloth coated with sludge. However, the above improvement will cause the direction of the cloth winding into the lower cloth winding machine to be changed. When the lower cloth winding shaft 420 winds the cloth, the reverse pulling force exerted on the support seat 200 by the cloth winding changes from the original second side to the first side, that is, the reverse direction of the cloth winding transmission direction changes from the first side to the second side, that is, the cloth winding transmission direction. The above change in direction causes the above-mentioned open mode on the support seat 200. When the cloth winding starts or stops, due to the fluctuation of the pulling force, it is easy to cause the lower cloth winding shaft 420 to vibrate, and the deviation rectifying effect of the deviation rectifying shaft 1000 is significantly affected. Even when winding the cloth, the lower cloth winding shaft 420 is disengaged from the opening, affecting the cloth sludge separation effect and efficiency.

[0057] In engineering practice, when the defects caused by the above improvement cannot be overcome, the improvement scheme of adding a roller between the deviation rectifying shaft 1000 and the cloth winding shaft 400 in the above-mentioned utility model cannot be directly implemented. Although adding a roller between the deviation rectifying shaft 1000 and the cloth winding shaft 400 has obvious effects, not all types of sludge necessarily adapt to this means and can also have a satisfactory sludge removal effect. In particular, the solution of the present application is not necessarily applicable to all types of sludge. There is a need for alternating or replacing the solution of directly entering the cloth wound out of the lower deviation rectifying shaft 820 into the lower cloth winding shaft 420 in the above-mentioned patent document CN114292004B and the solution of adding a roller between the deviation rectifying shaft 1000 and the cloth winding shaft 400 of the present utility model. This leads to the fact that in order to reduce the influence of the opening, usually only a non-easy-to-disassemble and assemble closed support seat 200 can be made. Otherwise, it is difficult to achieve frequent disassembly of the fixed support seat 200 of large mechanical equipment. However, the non-easy-to-disassemble and assemble closed support seat 200 will seriously affect the convenience and efficiency of the shaft replacement.

[0058] Therefore, based on this, the utility model provides a switch control device 700 which is arranged at the open end on the second side of the support seat 200 for installing the lower cloth winding shaft 420 and can control the open end to be open or closed. The defects caused by the reverse pulling force of the cloth roll on the cloth winding shaft 400 due to the upper and lower guide rollers 600 can be overcome. For example, when the cloth winding starts or stops, the lower cloth winding shaft 420 is prone to vibration due to the pulling force fluctuation, and the rectifying effect of the rectifying shaft 1000 is significantly affected. Another example is that when winding the cloth, the lower cloth winding shaft 420 disengages from the open end, affecting the cloth sludge separation effect and efficiency. Thus, the above technical means of the utility model can be implemented and the effects can be achieved. That is, when using the solution of adding a roller between the rectifying shaft 1000 and the cloth winding shaft 400 of the utility model, at this time, the direction of the cloth roll into the lower cloth winding machine is redirected, and the reverse pulling force exerted by the cloth roll on the support seat 200 when the lower cloth winding shaft 420 winds the cloth is from the first side to the second side, that is, the cloth transmission direction. At this time, rotate the rotating shaft of the rotating shaft component 730 in the switch control device 700, so that the connecting component slides in an arc on the horizontal plane, and thus the arc-shaped slider 750 connected to the connecting component slides into the arc-shaped groove 721 of the positioning component 720. The cooperation of the rotating shaft and the arc-shaped slider 750 can greatly reduce the influence of the vibration of the frame 100 in the front and back directions on the rotating shaft, that is, even if there is front and back vibration, it is not enough to cause the rotating shaft to rotate incorrectly left and right and malfunction, especially the arc design of the arc-shaped slider 750 further reduces the possibility of the above malfunction.

[0059] In the second embodiment, the upper spreading shaft 310 of the sludge spreading machine includes a first upper spreading shaft 311 and a second upper spreading shaft 312, and the lower spreading shaft 320 includes a first lower spreading shaft 321 and a second upper spreading shaft. Synchronous wheels are arranged at the ends of the shafts of each spreading shaft 300.

[0060] Such as Figure 1As shown in the figure, the sludge spreading machine further includes a spreading motor 800, a cloth winding motor 900, a deviation rectifying shaft 1000, a deviation rectifying motor, and a guiding shaft 900. The spreading motor 800 includes a first driving motor and a second driving motor. The synchronous pulleys of the first upper spreading shaft 311 and the first lower spreading shaft 321 are connected by a first synchronous belt, and the first driving motor drives the first upper spreading shaft 311 to rotate. The synchronous pulleys between the second upper spreading shaft 312 and the second lower spreading shaft 322 are connected by a second synchronous belt, and the second driving motor drives the second upper spreading shaft 312 to rotate. The cloth winding motor 900 includes an upper cloth winding motor 900 and a lower cloth winding motor 900. The upper cloth winding motor 900 drives the upper cloth winding shaft 410 to rotate, and the lower cloth winding motor 900 drives the lower cloth winding shaft 420 to rotate. The deviation rectifying shaft 1000 is installed on the frame body 100. The deviation rectifying shaft 1000 includes an upper deviation rectifying shaft 810 and a lower deviation rectifying shaft 820. The upper deviation rectifying shaft 810 is arranged between the second upper spreading shaft 312 and the upper guiding roller 500, and the lower deviation rectifying shaft 820 is arranged between the second lower spreading shaft 322 and the lower guiding roller 600. The deviation rectifying motor includes a first deviation rectifying motor and a second deviation rectifying motor. The first deviation rectifying motor drives the first deviation rectifying shaft 1000, and the second deviation rectifying motor drives the second deviation rectifying shaft 1000. The guiding shaft 900 is arranged between the second lower spreading shaft 322 and the lower deviation rectifying shaft 820.

[0061] During operation, the upper layer of fabric and the lower layer of fabric are separated at the spreading shaft 300. The upper layer of fabric sequentially passes through the first upper spreading shaft 311, the second upper spreading shaft 312, the upper deviation rectifying shaft 810, the upper guiding roller 500, and the upper cloth winding shaft 410, and the upper layer of fabric is wound at the upper cloth winding shaft 410. The lower layer of fabric sequentially passes through the first lower spreading shaft 321, the second lower spreading shaft 322, the guiding shaft 900, the lower deviation rectifying shaft 820, the lower guiding roller 600, and the lower cloth winding shaft 420, and the lower layer of fabric is wound at the lower cloth winding shaft 420. The upper driving motor drives the first upper spreading shaft 311 and the first lower spreading shaft 321 to rotate counterclockwise, and the lower driving motor 3 drives the second upper spreading shaft 312 and the second lower spreading shaft 322 to rotate clockwise, so as to perform spreading treatment on the upper and lower layers of fabric respectively. Due to the gravity factor, the sludge is always on the upper surface of the lower layer of fabric before the lower layer of fabric is transported to the lower cloth winding shaft 420 for winding. The upper deviation rectifying shaft 810 and the lower deviation rectifying shaft 820 are driven by the deviation rectifying motor to correct the fabric when the fabric deviates. The upper layer of fabric is wound from the second side below the upper cloth winding shaft 410, and the upper cloth winding shaft 410 rotates clockwise to wind the upper layer of fabric. The lower layer of fabric is wound from the second side below the lower cloth winding shaft 420, and the lower cloth winding shaft 420 rotates counterclockwise to wind the lower layer of fabric. When winding, the sludge drops from the lower layer of fabric due to gravity.
