Description

Technical Field

[0001] This application relates to the technical field of catalyst filtration, and more particularly, to a catalyst filtration device. Background Art

[0002] In petrochemical, fine chemical, and many other industrial fields, catalysts are one of the key factors in improving the efficiency of chemical reactions. With the continuous improvement of the requirements for resource utilization efficiency and the enhancement of environmental protection awareness, the efficient recovery and reuse of catalysts have become increasingly important. However, in practical applications, the filtration and recovery of catalysts often face a series of challenges, especially the blockage problem inside the filtration device, which directly affects the recovery rate of catalysts and the continuous operation ability of the filtration system;

[0003] In traditional catalyst filtration systems, due to the small size and easy caking of catalyst particles, the filter medium is easily blocked, resulting in an increase in the filtration pressure difference, which in turn affects the filtration effect and production capacity. To remove the blockage, it is usually necessary to regularly stop the filtration operation and disassemble the filter screen for cleaning, which not only increases the maintenance cost but also interrupts the continuous production process and reduces the production efficiency. Summary of the Utility Model

Wherein, the output end of the pump body is communicated with a liquid inlet pipe body, and the end of the liquid inlet pipe body penetrating into the inner cavity of the filter box is communicated with a spray head, and the spray head can spray the solution fed into the liquid inlet pipe body onto the filter plate part to perform reverse flushing on the reversed filter plate part.

[0009] According to some embodiments of the present application, a driving member is provided on one side of the filter plate portion and outside the filter box, and the shaft end of the filter plate portion penetrates to the outside of the filter box. Among them, the output end of the driving member and the shaft end of the filter plate portion extending to the outside of the filter box are both sleeved with continuous transmission members.

[0010] According to some embodiments of the present application, a plurality of movable receiving portions are symmetrically arranged in a ring shape on the outer side of the feeding cylinder, and the movable receiving portion includes a sliding rod member. Among them, one end of the sliding rod member is connected to the surface of the feeding cylinder.

[0011] According to some embodiments of the present application, a sleeve connection is sleeved on the outer surface of the movable receiving portion, and an elastic member is connected to the bottom of the inner cavity of the sleeve connection.

[0012] According to some embodiments of the present application, a discharge cylinder is installed at the bottom of the inner cavity of the filter box and located at the bottom of the feeding cylinder. A discharge hole is opened at the bottom of the inner cavity of the discharge cylinder. Among them, a liquid guiding pipe body communicates with the middle of the inner cavity of the discharge cylinder. At the same time, a liquid delivery pipe communicates with the bottom of the discharge cylinder.

[0013] According to some embodiments of the present application, the expansion chamber cylinder is slidably sleeved on the outer surface of the communication cylinder and makes a sealed sliding contact with its connection part. A sealing partition is arranged in the inner cavity of the expansion chamber cylinder. A sealing ring is sleeved on the outer surface of the sealing partition. At the same time, one side of the sealing partition is connected with a connecting rod, and the other end of the connecting rod is connected to the surface of the communication cylinder.

[0014] According to some embodiments of the present application, the other end of the sealing partition is connected with a guiding rod body, and the other end of the guiding rod body extends to one side of the bottom plate member and is connected with a sealing plug. The sealing plug is slidably inserted into the inner cavity of the liquid outlet groove hole in a sealed manner.

[0015] According to some embodiments of the present application, a pushing connecting rod body is installed on one side of the feeding cylinder, and the other end of the pushing connecting rod body penetrates to the outside of the filter box and is connected with a connecting disk.

[0017] The beneficial effects of the present application are as follows: The filter plate part can filter and separate the catalyst. When the filter plate part is blocked and needs to be backwashed, the filter plate part is driven by the driving member to rotate 180 degrees so that its front side faces downward. During the rotation of the filter plate part, under the action of the push-connecting disc and the push-connecting plate, the connecting disc and the push-connecting rod drive the feeding cylinder to displace. The displacement of the feeding cylinder causes the sealing partition plate to enter the bottom plate part to seal the bottom plate part. At the same time, the sealing plug rod disengages from the inner cavity of the liquid outlet groove hole, opening and closing the inner cavity of the liquid outlet groove hole. At this time, the external backwashing solution or the backwashing solution in the filter box is sent out through the nozzle, and the filter plate part can be flushed. At the same time, because the filter plate part is in a flipped state, the solution can more effectively backwash the filter plate part. The flushed solution finally flows back to the storage liquid sleeve through the liquid delivery pipe for storage. Moreover, the storage liquid sleeve can collect the refluxed solution for the next backwashing of the filter plate part. In this way, the filter plate part can be backwashed efficiently and continuously to avoid being blocked and affecting the filtration of the catalyst.

[0048] The following describes a catalyst filtration device according to an embodiment of the present application with reference to the accompanying drawings.

[0049] As Figures 1-12 shown, a catalyst filtration device according to an embodiment of the present application includes a filter box 100, and a liquid storage sleeve 110 for storing solution is sleeved outside the filter box 100; a bearing plate body 101 is fixedly connected to the rear side of the filter box 100 by bolts, and the bearing plate body 101 is used for fixedly supporting a driving member 210. A pump body 120 is erected above the liquid storage sleeve 110, and the output end of the pump body 120 is communicated with a pipeline and extends to the bottom of the inner cavity of the liquid storage sleeve 110; wherein, the output end of the pump body 120 is communicated with a liquid inlet pipe body 121, and the liquid inlet pipe body 121 penetrates through to the end of the inner cavity of the filter box 100 and is communicated with a spray head 130. The spray head 130 can spray the solution fed by the liquid inlet pipe body 121 onto the filter plate part 200 to perform backwashing on the flipped filter plate part 200;

[0050] Wherein, a slag discharge pipe is communicated with the bottom of the inner cavity of the liquid storage sleeve 110, and a conduit is communicated with the surface of the liquid inlet pipe body 121, which can feed external solution into the filter box 100 to perform backwashing on the filter plate part 200;

[0051] As a further optimization of this solution, a filtering member is installed at the bottom of the inner cavity of the liquid storage sleeve 110 and on the top of the pipeline communicated with the output end of the pump body 120. Therefore, when the pump body 120 pumps the solution for backwashing, the solution in the liquid storage sleeve 110 can be filtered;

[0052] Wherein, a filter plate part 200 is rotatably installed in the inner cavity of the filter box 100; to drive the filter plate part 200, a driving member 210 is arranged on one side of the filter plate part 200 and outside the filter box 100, and the bottom of the driving member 210 is installed on the top of the bearing plate body 101. The shaft end of the filter plate part 200 penetrates through to the outside of the filter box 100. Among them, connecting transmission members 211 are sleeved on the output end of the driving member 210 and the shaft end of the filter plate part 200 extending to the outside of the filter box 100. Preferably, the two connecting transmission members 211 are belt pulleys, and the two belt pulleys are connected by a belt;

[0053] As a further optimization of this solution, the continuous transmission member 211 can be two meshing gear members. Similarly, the continuous transmission member 211 can be two symmetrically arranged sprockets, and the two sprockets are driven by a chain;

[0054] A feeding cylinder 300 is slidably arranged at the bottom of the filter plate part 200 in the inner cavity of the filter box 100. A bottom plate member 310 is connected to the bottom of the inner cavity of the feeding cylinder 300. A plurality of discharge slot holes 311 are formed through the outer ring of the surface of the bottom plate member 310, and a liquid discharge slot hole 312 for discharging the backwashing solution is formed through the middle of the surface of the bottom plate member 310; A plurality of movable receiving parts 320 are symmetrically arranged in a ring on the outer side of the feeding cylinder 300. The movable receiving part 320 includes a sliding rod member 321. One end of the sliding rod member 321 is connected to the surface of the feeding cylinder 300;

[0055] A sleeve connection 322 is sleeved on the outer surface of the movable receiving part 320, and one end of the sleeve connection 322 is connected to the surface of the discharge cylinder 400. One end of the sliding rod member 321 penetrates to the bottom of the discharge cylinder 400 and is in sliding contact with its connection part. An elastic member 323 is connected to the bottom of the inner cavity of the sleeve connection 322, and the other end of the elastic member 323 is connected to the surface of the sliding rod member 321. The connection between the sleeve connection 322 and the sliding rod member 321 is in sliding contact. Therefore, when the feeding cylinder 300 moves, it can drive the sliding rod member 321 to move, increasing the stability of the movement of the feeding cylinder 300. And under the action of the elastic member 323, it can assist in driving the sliding rod member 321 to reset;

[0056] A discharge cylinder 400 is installed at the bottom of the feeding cylinder 300 in the inner cavity of the filter box 100. A discharge hole 410 is formed at the bottom of the inner cavity of the discharge cylinder 400. A liquid guide pipe body 420 communicates with the middle of the inner cavity of the discharge cylinder 400, and the end of the liquid guide pipe body 420 communicates with the inner cavity of the liquid discharge slot hole 312. The bottom of the connecting cylinder 500 communicates with the discharge hole 410;

[0057] Furthermore, the liquid guide pipe body 420 is composed of a fixed pipe and a telescopic hose. The two ends of the fixed pipe communicate with the liquid discharge slot hole 312 and the bottom of the inner cavity of the discharge cylinder 400 respectively;

[0058] At the same time, a liquid delivery pipe 600 is connected to the bottom of the discharge cylinder 400, and the other end of the liquid delivery pipe 600 extends to the bottom of the inner cavity of the liquid storage sleeve 110 for sending the backwashing solution into the liquid storage sleeve 110;

[0059] Meanwhile, a connecting cylinder 500 is provided at the bottom of the discharge chute hole 311, and an expanding cavity cylinder 510 is provided above the connecting cylinder 500. Among them, the expanding cavity cylinder 510 is communicated with the discharge chute hole 311. Therefore, the filtered catalyst can be sent out through the discharge chute hole 311, the sealing partition plate 520 and the sealing plug rod 530.

[0060] The expanding cavity cylinder 510 is slidably sleeved on the outer surface of the connecting cylinder 500 and makes a sealed sliding contact at the connection therewith. The inner cavity of the expanding cavity cylinder 510 is provided with a sealing partition plate 520. The connecting rod 521 and the sealing partition plate 520 are integrally formed. A sealing ring is sleeved on the outer surface of the sealing partition plate 520. Meanwhile, one side of the sealing partition plate 520 is connected with a connecting rod 521, and the other end of the connecting rod 521 is connected with the surface of the connecting cylinder 500. Among them, the specification of the sealing partition plate 520 is adapted to the inner cavity of the discharge chute hole 311. When the feeding cylinder 300 is forced to move, the sealing partition plate 520 can enter the discharge chute hole 311 to seal the inside of the discharge chute hole 311.

[0061] The other end of the sealing partition plate 520 is connected with a guiding rod body 531. The other end of the guiding rod body 531 extends to one side of the bottom plate member 310 and is connected with a sealing plug rod 530. The sealing plug rod 530 is sealed and slidably inserted into the inner cavity of the liquid discharge groove hole 312. Therefore, when the feeding cylinder 300 is forced to move and the sealing partition plate 520 is inserted into the discharge chute hole 311, the sealing plug rod 530 disengages from the inner cavity of the liquid discharge groove hole 312. Similarly, when the sealing partition plate 520 is in the inner cavity of the expanding cavity cylinder 510, the sealing plug rod 530 is inserted into the inner cavity of the liquid discharge groove hole 312, so that when the discharge chute hole 311 is in an open or closed state, the liquid discharge groove hole 312 is in a closed state.

[0062] Therefore, during the catalyst filtration, the filter plate part 200 is used to filter the catalyst entering the filter box 100. The filtered catalyst enters the sealing partition plate 520 through the discharge chute hole 311, is sent to the bottom of the filter box 100 through the connecting cylinder 500 and is discharged through the bottom of the filter box 100.

[0063] A pushing connecting rod body 700 is installed on one side of the feeding cylinder 300. The other end of the pushing connecting rod body 700 penetrates to the outside of the filter box 100 and is connected with a connecting disc 720. A pushing connecting plate 730 is arranged above the connecting disc 720, and the pushing connecting plate 730 is sleeved on the shaft end of the filter plate part 200.

[0064] One end of the surface of the connecting plate 720 and the surface of the push-connecting plate 730 are movably connected through the push-connecting plate 730, and the connection between the surface of the push-connecting plate 730 and the connecting plate 720 and the push-connecting plate 730 is a movable connection. Among them, a chute for cooperating with the push rod body 700 is provided on the surface of the filter box 100, and a limiting sliding seat 740 is installed in the inner cavity of the chute. Among them, telescopic soft pads are connected to both ends of the inner cavity of the limiting sliding seat 740, and the other ends of the telescopic soft pads are connected to the surface of the push rod body 700;

[0065] Therefore, when the filter plate part 200 is turned over, the rotation of its shaft end can drive the connecting plate 720 to drive the push rod body 700 to move through the push disc 710 and the push-connecting plate 730, causing the feeding cylinder 300 to displace, so that the sealing partition 520 closes the inner cavity of the discharge chute hole 311, and the sealing plug rod 530 disengages from the liquid outlet chute hole 312, opening the inner cavity of the liquid outlet chute hole 312 for subsequent backwashing work.

[0066] Specifically, the working principle of this catalyst filtering device: The filter plate part 200 can be used to filter and separate the catalyst. When the filter plate part 200 is blocked and needs to be backwashed, the filter plate part 200 is driven by the driving part 210 to turn 180 degrees so that its front side faces down. During the rotation of the filter plate part 200, under the action of the push disc 710 and the push-connecting plate 730, the connecting plate 720 and the push rod body 700 drive the feeding cylinder 300 to displace. The displacement of the feeding cylinder 300 causes the sealing partition 520 to enter the bottom plate part 310 to seal the bottom plate part 310. At the same time, the sealing plug rod 530 disengages from the inner cavity of the liquid outlet chute hole 312, opening the inner cavity of the liquid outlet chute hole 312. At this time, the external backwashing solution or the backwashing solution in the filter box 100 is sent out through the nozzle 130 to scour the filter plate part 200. At the same time, because the filter plate part 200 is in a turned-over state, the solution can more effectively backwash the filter plate part 200, and the rinsed solution finally flows back to the storage sleeve 110 through the liquid delivery pipe 600 for storage. And the storage sleeve 110 can collect the refluxed solution for the next backwashing of the filter plate part 200. In this way, the filter plate part 200 is backwashed efficiently and continuously to prevent it from being blocked and affecting the filtration of the catalyst.

[0067] It should be noted that the specific model specifications of the pump body 120 and the driving part 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0068] The power supply and its principle of the pump body 120 and the driving part 210 are clear to those skilled in the art and will not be elaborated here.

[0069] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
