Description

Technical Field

[0001] The invention belongs to the technical field of sludge treatment, and in particular to a sludge feeder, method and application. Background Art

[0002] In the sludge treatment system, the function of the feeder 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 feeder and is then transported and discharged by the cage machine. The feeder can be set on different and opposite sides of the conveyor's moving path with the feeder 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, it was found in actual engineering practice that the solution in the above patent document that the cloth that is wound around the lower correction shaft directly enters the lower cloth rolling shaft is easy to form a firm bond with the front side of the cloth covering the sludge that has been squeezed dry, and some types of sludge are easy to form a firm bond with the front side of the cloth covering the sludge, making it difficult for the above solution to achieve a satisfactory sludge separation effect under some working conditions in the project, seriously affecting the cloth rolling efficiency and the recycling of the cloth rolling.

[0006] The inventor accidentally discovered that the invention adds a roller between the deviation correction shaft and the cloth rolling shaft, and the roller is wound around the back of the cloth wrapped with sludge and acts on the back and the sludge bonded to the front of the cloth through the roller, which can greatly improve the effect of separating the sludge firmly bonded to the front of the cloth wrapped with sludge. However, the above improvement will cause the direction of the cloth being rolled into the lower cloth rolling machine to be changed. When the lower cloth rolling shaft rolls the cloth, the reverse pulling force applied by the support seat to the cloth is directed from the original second side to the first side, that is, the reverse direction of the cloth transmission direction is changed from the first side to the second side ( Figure 2 The solid line in the middle indicates the improved way of the cloth rolling into the lower cloth rolling shaft, i.e. the cloth rolling transmission direction. The above-mentioned opening on the support seat caused by the above-mentioned change of direction will easily cause the lower cloth rolling shaft to vibrate due to the tension fluctuation when the cloth rolling is started or closed, and the correction function of the correction shaft will be significantly affected. It may even cause the lower cloth rolling shaft to detach from the opening when the cloth is rolled, affecting the cloth mud separation effect and efficiency.

[0007] In engineering practice, when the defects caused by the above improvements cannot be overcome, the above-mentioned improvement scheme of adding a roller between the deflection correction shaft and the cloth rolling shaft of the present invention cannot be directly implemented. Although the above-mentioned addition of a roller between the deflection correction shaft and the cloth rolling shaft has obvious effects, not all types of sludge are necessarily suitable for this method and can also have satisfactory desludging effects. In particular, the scheme of the present application is not necessarily applied to all types of sludge. The scheme in the above-mentioned patent document that the cloth that goes out of the lower deflection correction shaft directly enters the lower cloth rolling shaft and the scheme of the present invention that adds a roller between the deflection correction shaft and the cloth rolling shaft have the need to be used alternately or replaced. This leads to the fact that in order to reduce the impact of the exposure, usually only a closed support seat that is not easy to disassemble can be made. Otherwise, it is difficult to frequently disassemble the fixed support seat of large mechanical equipment, but the closed support seat that is not easy to disassemble will seriously affect the convenience and efficiency of the shaft replacement.

The lower layer of cloth is wound into and wound around the lower cloth winding shaft 420 from the second side of the lower part of the lower cloth winding shaft 420 with the second side 1020.

[0051] In actual engineering, the inventors found that the solution in the background technology patent document CN114292004B, in which the cloth that is wound around the lower deviation correction shaft 820 directly enters the lower cloth rolling shaft 420, is easy to form a firm bond with the front side of the cloth covering the sludge for some types of sludge that have been squeezed dry, making it difficult to achieve a satisfactory sludge separation effect under some working conditions in the project, seriously affecting the cloth rolling efficiency and the recycling of the cloth rolling.

[0052] The inventor accidentally discovered that the invention adds a roller between the deflection correction shaft 1000 and the cloth rolling shaft 400, and the roller is wound around the back of the cloth wrapped with sludge and acts on the back and the sludge bonded to the front of the cloth through the roller, which can greatly improve the separation effect of the surface of the cloth wrapped with sludge. However, the above improvement will cause the direction of the cloth rolled into the lower cloth rolling machine to be changed. When the lower cloth rolling shaft 420 rolls the cloth, the reverse pulling force applied to the support seat 200 by the cloth rolling is directed from the original second side to the first side, that is, the reverse direction of the cloth rolling transmission direction is changed from the first side to the second side, that is, the cloth rolling transmission direction. The above redirection causes the above opening on the support seat 200, which will easily cause the lower cloth rolling shaft 420 to vibrate due to the fluctuation of the pulling force when the cloth is started or closed, and the deflection correction effect of the deflection correction shaft 1000 is significantly affected. Even when the cloth is rolled, the lower cloth rolling shaft 420 will be separated from the opening, affecting the cloth mud separation effect and efficiency.

[0053] In engineering practice, when the defects caused by the above improvements cannot be overcome, the improvement scheme of adding a roller between the deflection correction shaft 1000 and the cloth rolling shaft 400 of the present invention cannot be directly implemented. Although the above-mentioned addition of a roller between the deflection correction shaft 1000 and the cloth rolling shaft 400 has obvious effects, not all types of sludge are necessarily adapted to this method and can also have satisfactory desludge effects. In particular, the scheme of the present application is not necessarily applied to all types of sludge. The scheme of the cloth winding out of the lower deflection correction shaft 820 directly entering the lower cloth rolling shaft 420 in the above-mentioned patent document CN114292004B and the scheme of adding a roller between the deflection correction shaft 1000 and the cloth rolling shaft 400 of the present invention have the need to be used alternately or replaced, which leads to the fact that in order to reduce the impact of the opening, usually only a closed support seat 200 that is not easy to disassemble can be made. Otherwise, it is difficult to frequently disassemble the fixed support seat 200 of large mechanical equipment, but the closed support seat 200 that is not easy to disassemble will seriously affect the convenience and efficiency of the shaft replacement.

[0054] Therefore, on this basis, the present invention sets a switch control device 700 that can control the opening to be open or closed at the opening of the second side of the support seat 200 where the lower cloth rolling shaft 420 is installed. The defects caused by the redirection of the reverse pulling force on the cloth rolling shaft 400 caused by the upper and lower guide rollers 600 can be overcome, wherein the defects such as the vibration of the lower cloth rolling shaft 420 due to the fluctuation of the pulling force when the cloth rolling is started or closed, and the correction effect of the correction shaft 1000 is obviously affected. Another example is that when the cloth is rolled, the lower cloth rolling shaft 420 is separated from the opening, which affects the cloth mud separation effect and efficiency. Thus, the above technical means of the present invention can be implemented and the effect can be achieved. That is, when using the solution of adding a roller between the correction shaft 1000 and the cloth rolling shaft 400 of the present invention, at this time, the direction of the cloth rolling into the lower cloth rolling machine is redirected, and when the lower cloth rolling shaft 420 rolls the cloth, the reverse pulling force applied by the support seat 200 to the cloth is directed from the first side to the second side, that is, the cloth rolling transmission direction. At this time, the rotating shaft of the rotating shaft component 730 in the switch control device 700 is rotated, so that the connecting component slides in an arc shape on the horizontal plane, so that the arc-shaped slider 750 connected to the connecting component slides into the arc-shaped groove 721 of the positioning component 720. 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. Even if there is front and back vibration, it is not enough to cause the rotating shaft to rotate left and right incorrectly and open by mistake. In particular, the arc-shaped design of the arc-shaped slider 750 further reduces the possibility of the above-mentioned accidental opening.

The spreading motor 800 includes a first drive motor and a second drive motor. The synchronous wheels of the first upper spreading shaft 311 and the first lower spreading shaft 321 are connected by a first synchronous belt. The first drive motor drives the first upper spreading shaft 311 to rotate. The synchronous wheels of the second upper spreading shaft 312 and the second lower spreading shaft 322 are connected by a second synchronous belt. The second drive motor drives the second upper spreading shaft 312 to rotate. The rolling motor 900 includes an upper rolling motor 900 and a lower rolling motor 900. The upper rolling motor 900 drives the upper rolling shaft 410 to rotate, and the lower rolling motor 900 drives the lower rolling shaft 420 to rotate. The deflection correction shaft 1000 is installed on the frame 100, and the deflection correction shaft 1000 includes an upper deflection correction shaft 810 and a lower deflection correction shaft 820. The upper deflection correction shaft 810 is arranged between the second upper spreading shaft 312 and the upper guide roller 500, and the lower deflection correction shaft 820 is arranged between the second lower spreading shaft 322 and the lower guide roller 600. The deflection correction motor includes a first deflection correction motor and a second deflection correction motor. The first deflection correction motor drives the first deflection correction shaft 1000, and the second deflection correction motor drives the second deflection correction shaft 1000. The guide shaft 900 is arranged between the second lower spreading shaft 322 and the lower deflection correction shaft 820.

[0057] During operation, the upper fabric is separated from the lower fabric at the fabric spreading shaft 300, and the upper fabric passes through the first upper fabric spreading shaft 311, the second upper fabric spreading shaft 312, the upper deflection correction shaft 810, the upper guide roller 500, and the upper fabric rolling shaft 410 in sequence, and the upper fabric is rolled up at the upper fabric rolling shaft 410.

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 spread the upper and lower layers of cloth respectively. Due to gravity, the sludge is on the upper surface of the lower cloth before the lower cloth is transported to the lower cloth rolling shaft 420 for rolling up. The upper correcting shaft 810 and the lower correcting shaft 820 are driven by the correcting motor, and the cloth is corrected when it deviates. The upper cloth is rolled in from the second side of the lower part of the upper cloth rolling shaft 410, and the upper cloth rolling shaft 410 rotates clockwise to roll up the upper cloth, and the lower cloth is rolled in from the second side of the lower part of the lower cloth rolling shaft 420, and the lower cloth rolling shaft 420 rotates counterclockwise to roll up the lower cloth. When rolling, the sludge falls from the lower cloth due to gravity.
