Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to an electroplating sludge pressure filter collection device. Background Technology

[0002] Electroplating is a surface treatment technology used in industrial production to improve the corrosion resistance and aesthetics of metal surfaces. However, electroplating operations generate a large amount of wastewater containing harmful substances such as metal ions, acids, and alkalis. These substances are harmful to human health and the environment, so electroplating wastewater needs to be treated. One final step in electroplating wastewater treatment is sludge dewatering. This involves using a filter press to dewater the treated electroplating wastewater, pressing the sludge into sludge cakes to remove the sludge from the wastewater.

[0003] After the sludge in the electroplating wastewater is pressed into sludge cakes by the filter press, the filter press is operated to drop the sludge cakes onto the conveyor belt below. The conveyor belt then transports the sludge cakes to the loading truck for transfer. However, we found that this requires the loading truck to reach the conveyor belt position before loading can begin. If the loading truck has not reached the position, there is a waiting time, which reduces the treatment speed of the electroplating wastewater and greatly reduces the filtration efficiency of the electroplating wastewater.

[0004] Therefore, how to provide a filter press collection device for electroplating sludge is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an electroplating sludge depressurization and collection device. This invention solves the problem in the prior art that the depressurization efficiency of electroplating wastewater is greatly reduced because it requires waiting for the transport vehicle to reach the conveyor belt position before loading can begin, and if the transport vehicle has not yet reached the conveyor belt position, there is still a waiting period.

[0006] An electroplating sludge filter press collection device according to an embodiment of the present invention includes a filter press frame. A drop groove is provided at the bottom of the filter press frame, and a hopper is provided at the bottom of the filter press frame corresponding to the drop groove. A conveyor belt is provided at the bottom of the filter press frame directly below the hopper. A lifting hook assembly is provided on the lower surface of the filter press frame at the downward inclined end of the conveyor belt. A lifting strap is attached to the lifting hook assembly, and a woven ton bag is provided on the lifting strap. The opening of the woven ton bag is located directly below the downward inclined end of the conveyor belt. A support rod is provided at the bottom of the filter press frame outside the woven ton bag. The filter press frame is stably supported on the ground by the support rod.

[0007] The lifting hook assembly includes two fixed plates, four hanging plates, and four hook assemblies. The two fixed plates are fixed to the lower surface of the filter press frame near both sides. Every two hanging plates are fixed to the lower surface of the fixed plates near both ends. The four hook assemblies are respectively set at the bottom of the four hanging plates.

[0008] Each hook assembly includes a hook body, a rotating groove, a rotating shaft, and a side plate. The rotating groove is located at the bottom of the hanging plate, and the rotating shaft is fixed inside the rotating groove. The hook body is movably sleeved on the surface of the rotating shaft, and the hook part of the hook body is tilted upwards towards one side of the hanging plate. The lifting strap is hung on the hook part of the hook body, and the side plate is fixed on the other side of the hanging plate. An elastic component is provided on the side plate, and one end of the elastic component abuts against the surface of the hook.

[0009] The elastic component includes a movable rod and a spring. The movable rod is movable on the side plate, and both ends of the movable rod are set as protrusions. One end of the movable rod extends to the surface of the hook body. The spring is movably sleeved on the surface of the movable rod located between the side plate and the hook body. One end of the spring is attached to the side plate, and the other end of the spring is attached to the protruding surface on the movable rod.

[0010] The support rod is equipped with a placement platform assembly located below the woven ton bag. The placement platform assembly includes a base plate, a buffer damping component, and a movable top plate. The base plate is fixed to the support rod, and the movable top plate is movably sleeved on the surface of the support rod. The buffer damping component is fixed to the top of the base plate, and the top of the buffer damping component is fixed to the bottom of the movable top plate. The woven ton bag is placed on the movable top plate.

[0011] The buffer damping component includes a damping rod, a fixed cylinder, and a buffer spring. The fixed cylinder is fixed to the top of the base plate. One end of the damping rod is movable inside the fixed cylinder. The buffer spring is movably sleeved on the surface of the damping rod located outside the fixed cylinder. The bottom end of the buffer spring is attached to the top of the fixed cylinder, and the top end of the buffer spring is attached to the protruding position of the damping rod.

[0012] The movable top plate has two sets of forklift slots.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a lifting hook assembly, lifting belt, and woven ton bags, the sludge cake falls onto the conveyor belt through a drop chute. The conveyor belt then transports the sludge cake to the woven ton bag position, where it falls onto the bag for bagging. Once the woven ton bag is full, it can be transported to a designated location by a forklift. This eliminates the need to wait for the transport vehicle to arrive before processing the sludge cake, achieving the effect of pre-bagging the sludge cake with woven ton bags. This solves the problem in existing technologies where loading requires waiting for the transport vehicle to reach the conveyor belt position, and if the transport vehicle has not yet reached the conveyor belt position, there is still a waiting period, which greatly reduces the pressure filtration efficiency of electroplating wastewater.

[0015] By setting up a placement platform assembly and a lifting hook assembly, the lifting hook assembly hooks the lifting strap. When the sludge cake is loaded into the woven ton bag, the weight changes, and the movable top plate presses down on the buffer damping component to shrink it. This causes the movable top plate to move downward, which in turn moves the woven ton bag downward, pulling the lifting hook assembly and causing the hook body on the lifting hook assembly to rotate. When the movable top plate reaches the bottom, the lifting strap separates from the hook body. This achieves the purpose of automatically separating the lifting strap from the hook body without manual operation. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The system includes a filter press frame 1, which is the frame of the filter press. The filter press frame 1 also includes filter plates and other components of the filter press. The filter press uses the filter plates to filter sludge from electroplating wastewater. The sludge is compressed into a cake shape before passing through the filter plates, hence the name "sludge cake." A drop groove 2 is provided at the bottom of the filter press frame 1, and a hopper 3 is positioned at the bottom of the filter press frame 1 corresponding to the drop groove 2. The hopper 3 is mainly used to guide the falling sludge cake. A conveyor belt is located at the bottom of the filter press frame 1 directly below the hopper 3. Belt 4 guides the sludge cake to fall onto conveyor belt 4 and reach the downward-sloping end face of conveyor belt 4. A hook assembly 5 is provided on the lower surface of filter press frame 1 at the downward-sloping end of conveyor belt 4. The hook assembly 5 is mainly used to hook the lifting straps 6 on the woven ton bag 7, thus opening the entire entrance of the woven ton bag 7. The hook assembly 5 includes two fixing plates 9, four hanging plates 10, and four hook assemblies 11. The two fixing plates 9 are respectively fixed to the lower surface of filter press frame 1 near both sides. The positions are such that every two hanging plates 10 are fixed to the lower surface of the fixed plate 9 near both ends, and four hook assemblies 11 are respectively set at the bottom of the four hanging plates 10. The hook assemblies 11 are provided at all four positions. When the hook assemblies 11 hook the lifting straps 6, the opening of the woven ton bag 7 will be opened, thus facilitating feeding. The lifting straps 6 are hung on the lifting hook assembly 5 and are stably hung on the lifting hook assembly 5. The woven ton bag 7 is set on the lifting straps 6. The bag opening of the woven ton bag 7 is located directly below the downward inclined end of the conveyor belt 4. The bottom of the filter press frame 1 is located on the outside of the woven ton bag 7 and is provided with support rods 8. The filter press frame 1 is stably supported on the ground by the support rods 8. The four support rods 8 stably place the filter press frame 1 on the ground. During operation, first, the four lifting straps 6 on the woven ton bag 7 are hooked on the four hook assemblies 11, and then the feeding operation can be carried out, so that the sludge cake reaches the position of the woven ton bag 7 from the conveyor belt 4 and finally falls into the woven ton bag 7 through the conveyor belt 4 for filling.

[0025] refer to Figure 2 and Figure 4Each hook assembly 11 includes a hook body 12, a rotating groove 13, a rotating shaft 14, and a side plate 15. The rotating groove 13 is located at the bottom end of the hanging plate 10, and the rotating shaft 14 is fixed inside the rotating groove 13. The hook body 12 is movably sleeved on the surface of the rotating shaft 14, and the hook end of the hook body 12 is tilted upwards towards one side of the hanging plate 10. Only when tilted upwards can the carrying strap 6 be hooked; otherwise, the carrying strap 6 can easily fall off. The carrying strap 6 is hooked on the hook end of the hook body 12, and the side plate 15 is fixed to the other side of the hanging plate 10. An elastic component 16 is provided on the side plate 15, which includes a movable rod 17 and a spring 18. The movable rod 17 moves on the side plate 15, and both ends of the movable rod 17 are set as protrusions to limit the movable rod 17, so that the movable rod 17 can only move left and right on the side plate 15. One end of the movable rod 17 extends to the surface of the hook body 12, and the spring 18 is movably sleeved on the movable rod 17 located at the hook end of the hanging plate 10. The surface between the side plate 15 and the hook body 12 has one end of the spring member 18 attached to the side plate 15 and the other end attached to the protruding surface of the movable rod 17. One end of the elastic component 16 abuts against the surface of the hook. Under the elastic force of the spring member 18, the spring member 18 will squeeze the movable rod 17, so that one end of the movable rod 17 abuts against the side of the hook body 12. This will cause the hook of the hook body 12 to tilt upward. After the woven ton bag is filled with materials, the woven ton bag 7 will be expanded. When it is necessary to remove the carrying strap 6, there is no need to manually lift the carrying strap 6 upward. Just pull the carrying strap 6 downward. At this time, the carrying strap 6 will squeeze the hook body 12, causing the hook body 12 to rotate around the pivot 14 and squeeze the movable rod 17. Under the compression, the movable rod 17 moves away from the hook body 12 and squeezes the spring member 18. Then, under the rotation, the hook body 12 will move downward at the hook, causing the carrying strap 6 to fall off the hook body 12, thus achieving the purpose of conveniently removing the carrying strap 6.

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5A placement platform assembly 19 is provided below the woven ton bag 7 on the support rod 8. The placement platform assembly 19 includes a base plate 20, a buffer damping element 21, and a movable top plate 22. The base plate 20 is fixed to the support rod 8, and the movable top plate 22 is movably sleeved on the surface of the support rod 8. The buffer damping element 21 is fixed to the top of the base plate 20, and the top of the buffer damping element 21 is fixed to the bottom of the movable top plate. The woven ton bag 7 is placed on the movable top plate 22. The movable top plate 22 has two sets of forklift slots 26, which are used to insert two forklift rods into the lower part of the movable top plate 22. When lifting upwards, the woven ton bag 7 can be directly inserted through the movable top plate 22 for transfer. The buffer damping element 21 includes a damping rod 23 and a fixing cylinder 24. 4 and buffer spring 25, fixed cylinder 24 is fixed to the top of base plate 20, one end of damping rod 23 is movable inside fixed cylinder 24, buffer spring 25 is movably sleeved on the surface of damping rod 23 located outside fixed cylinder 24, bottom end of buffer spring 25 is attached to top of fixed cylinder 24, top end of buffer spring 25 is attached to protrusion of damping rod 23. In order to facilitate the removal of lifting strap 6, a cushioning placement platform assembly 19 is also provided here. During operation, after the sludge cake enters the woven ton bag 7 little by little, the weight of woven ton bag 7 will become heavier, and then the heavier woven ton bag 7 will press down on movable top plate 22. Movable top plate 22 slides down along support rod 8 to press the buffer damping component 21, so that the buffer damping component 21 shrinks under compression. The woven ton bag 7 will move downwards along with the movable top plate 22. This downward movement of the woven ton bag 7 will pull the lifting strap 6, causing the lifting strap 6 to move downwards and pull the hook body 12. Under the influence of the lifting strap 6, the hook body 12 will rotate around the pivot 14. This rotation of the hook body 12 will move the hook downwards. When the woven ton bag 7 is almost full, both the woven ton bag 7 and the movable top plate 22 will reach their bottom. At this point, the lifting strap 6 will separate from the hook body 12 under the pull of the woven ton bag 7. This achieves the effect of automatically separating the lifting strap 6 from the hook body 12 when the woven ton bag 7 is almost full, without manual operation. Then, the forklift is inserted under the movable top plate 22 and lifted upwards. The forklift will then pass through the forklift slot 26 and contact the bottom of the woven ton bag 7, lifting the woven ton bag. The bag 7 is inserted for transfer, which is simple to operate. This eliminates the need to wait for the loading vehicle to arrive before the sludge cake can be dropped. The sludge cake is transferred through the woven ton bag 7. Each time it is used, the sludge cake is loaded into the woven ton bag 7. After the woven ton bag 7 is full, it is transported to the designated location by forklift. The loading vehicle can directly go to the location to load it. There is no need to wait for the loading vehicle to arrive before unloading. This allows the filter press to operate continuously, which greatly improves the filter press efficiency. It should be noted that after the lifting belt 6 is separated from the hook body 12, the hook body 12 will be driven by the elastic force of the spring 18 to drive the movable rod 17 to continue to press against the side of the hook body 12 to restore the hook body 12 to its original position, so that the next lifting belt 6 can be hooked.
