Description

Technical Field

[0001] The present application relates to the field of gas-solid separation, and in particular, to a lifting filter for separating solid substances in air. Background Art

[0002] A factory building is one of the main places for industrial production. Many machining processes need to be carried out in the factory building. In order to ensure the industrial production environment, an air outlet device must be installed in the factory building to directly discharge the air containing solid substances such as dust to the outside. However, it will cause serious pollution to the air in the external environment. Therefore, in order to reduce the impact of the air discharged by the air outlet device on the environment, it is necessary to improve the filtering effect of the air outlet device.

[0003] For example, the utility model patent with the patent publication number CN213159788U discloses a lifting filter for the installation of an air outlet device, including a fixing structure fixed at the air outlet of the air outlet device, a filtering structure arranged in the fixing structure, and a lifting device for lifting the filtering structure into the fixing structure or lowering it for replacing the filtering structure and reciprocating. The fixing structure includes an outer frame, fixing members arranged on the periphery of the outer frame, and a slideway arranged in the frame body for the filtering structure to lift through. The lifting device includes a frame body arranged on the frame, a rotating shaft arranged on the frame body, a winding disc arranged on the rotating shaft, a lifting belt arranged in the winding disc and passing through the outer frame to be connected with the filtering structure, and a driving device for driving the rotating shaft to rotate. It can perform low-altitude operations, with a high safety factor and low operation difficulty.

[0004] When using the above-mentioned lifting filter, when the filtering structure descends to break away from the outer frame for replacement, the lifting belt will shake under the movement and noise generated during the replacement operation, resulting in continuous friction and wear between the lifting belt and the outer frame, shortening the service life of the lifting belt, which needs to be improved. Summary of the Invention

[0005] In order to extend the service life of the lifting belt, the present application provides a lifting filter for separating solid substances in air.

[0006] A lifting filter for separating solid substances in air provided by the present application adopts the following technical solutions:

[0007] A lifting filter for separating solid substances in air, comprising a frame body and a filter plate that lifts and slides on the frame body. A receiving groove is formed on the lower end surface of the frame body, and the filter plate is located in the receiving groove. A rotating shaft is rotatably connected to the frame body, and a lifting belt is wound around the rotating shaft. The lifting belt is connected to the filter plate. The frame body is also provided with a driving member for driving the rotating shaft to rotate. A limiting plate is liftably and slidably arranged in the receiving groove, and the limiting plate is located above the filter plate. The lifting belt penetrates through the limiting plate. A limiting rod is arranged on the limiting plate, and the limiting rod liftably and slidably moves on the filter plate. The frame body is provided with a positioning member for positioning the limiting plate.

[0008] By adopting the above technical solution, the limiting plate and the limiting rod are provided. When the filter plate descends to be separated from the frame body, the limiting plate is moved down to the lower end of the receiving groove and positioned, which can shorten the length of the limiting rod. At this time, the filter plate is limited by the limiting rod abutting against the filter plate and the limiting plate abutting against the inner peripheral wall of the receiving groove, so that the lifting belt remains stationary relative to the frame body, thereby reducing the situation that the lifting belt shakes and continuously rubs against the frame body to cause wear, which is beneficial to prolonging the service life of the lifting belt and improving the resource utilization rate.

[0009] Optionally, the limiting plate and the filter plate are detachably connected.

[0010] By adopting the above technical solution, when the filter plate descends, it drives the limiting plate to descend, which can reduce the situation that the limiting plate is stuck by the frame body, and further reduce the situation that employees perform high-altitude operations to push the limiting plate to move, improving the safety of using the lifting filter.

[0011] Optionally, a movable block is slidably connected to the limiting plate, and the movable block slides close to or away from the limiting plate. An elastic member is arranged on the limiting plate, and the elastic member abuts against the movable block, so that the movable block has a tendency to move close to the limiting plate. A fixed block is arranged on the filter plate, and a card slot for the fixed block to be inserted into is formed on the movable block. The fixed block is located on one side of the card slot close to the limiting plate.

[0012] By adopting the above technical solution, when the filter plate descends to be separated from the frame body, the movable block is moved away from the limiting plate, so that the fixed block is separated from the card slot, and the connection state between the limiting plate and the filter plate can be released. The limiting plate is inserted into the receiving groove for positioning. When the filter plate is replaced, the positioning state between the limiting plate and the frame body is released, the limiting plate is moved to align the fixed block and the card slot, and then the movable block is released. The movable block moves close to the limiting plate under the action of the elastic member, so that the fixed block is inserted into the card slot. By the fixed block abutting against the inner wall of the card slot, the connection between the limiting plate and the filter plate can be realized, making it more convenient to remove the limiting plate from the filter plate or connect the limiting plate to the filter plate.

[0013] Optionally, the positioning member is located in the accommodating groove, the movable block is rotatably connected with a connecting block, the connecting block is located on the side of the movable block away from the limiting plate, and a threaded groove is provided on the end surface of the connecting block away from the movable block, and the threaded groove is provided for threaded connection of the positioning member.

[0014] By adopting the above technical solution, the positioning of the limit plate on the frame can be achieved through the threaded cooperation between the positioning member and the connecting block, and under the action of the elastic member, the threads on the positioning member and the connecting block are pressed against each other, thereby improving the positioning stability of the limit plate on the frame.

[0015] Optionally, the lifting belt includes a belt body wound around the rotating shaft and a mounting block arranged on the belt body, the filter plate is provided with a mounting groove, the mounting groove is for the mounting block to be inserted into, the mounting block is provided with a slot, and the filter plate is rotatably connected with an insert block, and the slot is for the insert block to be inserted into.

[0016] By adopting the above technical solution, when the filter plate needs to be replaced, the plug block can be rotated to disengage the plug block from the slot, and then the mounting block can be taken out of the mounting slot, and the filter plate can be removed from the lifting belt for replacement. When the filter plate is replaced, the mounting block is inserted into the mounting slot so that the plug block and the slot are aligned, and then the plug block is rotated to insert the plug block into the slot. The connection between the lifting belt and the filter plate can be achieved by abutting the mounting block with the plug block. No tools are required for removal and installation, making it more convenient to connect the lifting belt and the filter plate or to disassemble the lifting belt and the filter plate.

[0017] Optionally, the limit rod is provided with a plurality of limit grooves 1, which are distributed along the sliding direction of the limit rod, and a slider is slidably connected to the filter plate, and the slider slides close to or away from the limit rod, and the limit grooves 1 are for the slider to be inserted into.

[0018] By adopting the above technical solution, when the filter plate is lowered to be separated from the frame for cleaning, the length of the lifting belt increases, the flexibility increases, and the risk of the filter plate being broken under the action of gravity for a long time also increases. The slider is inserted into the corresponding limit groove 1, and the slider abuts against the bottom inner wall of the corresponding limit groove 1, so that the limit plate and the limit rod share the pressure applied by the filter plate to the lifting belt, which is beneficial to further extend the service life of the lifting belt.

[0019] Optionally, a second limiting groove for the slider to be inserted into is formed on the insert block. When the limiting plate abuts the filter plate, the limiting rod abuts the slider, the slider is inserted into the second limiting groove, and the insert block is inserted into the slot. When the slider is inserted into the first limiting groove, the slider is disengaged from the second limiting groove.

[0020] By adopting the above technical solution, after the insertion block is inserted into the slot, move the slider so that the slider is inserted into the second limiting groove, and then connect the limiting plate to the filter plate so that the limiting plate remains in a state of abutting against the filter plate. At this time, the limiting rod abuts against the slider, and the slider abuts against the inner wall of the second limiting groove, so as to keep the insertion block inserted into the slot, reducing the situation that the insertion block disengages from the slot and improving the connection stability between the lifting belt and the filter plate; when cleaning or replacing the filter plate, insert the slider into the first limiting groove to reduce the pressure on the lifting belt. At the same time, the slider disengages from the second limiting groove, and the insertion block can be rotated at any time to release the connection state between the lifting belt and the filter plate, simplifying the operation steps and making it more convenient to replace the filter plate.

[0021] Optionally, a Z-shaped flange is provided on the frame body.

[0022] By adopting the above technical solution, the Z-shaped flange is provided to make the installation method of the lifting filter more diversified.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the filter plate descends to disengage from the frame body, move the limiting plate downward and position it. The limiting rod abuts against the filter plate and the limiting plate abuts against the inner peripheral wall of the receiving groove, thereby limiting the filter plate and keeping the lifting belt stationary relative to the frame body. This reduces the situation that the lifting belt shakes and continuously rubs against the frame body, which is beneficial to extending the service life of the lifting belt and improving resource utilization rate;

[0025] 2. When the filter plate descends to disengage from the frame body for cleaning, insert the slider into the corresponding first limiting groove. By the slider abutting against the bottom inner wall of the corresponding first limiting groove, the limiting plate together with the limiting rod share the pressure exerted by the filter plate on the lifting belt, which is beneficial to further extending the service life of the lifting belt;

[0026] 3. After the insertion block is inserted into the slot, move the slider so that the slider is inserted into the second limiting groove, and then connect the limiting plate to the filter plate, keeping the insertion block inserted into the slot, improving the connection stability between the lifting belt and the filter plate. When cleaning or replacing the filter plate, insert the slider into the first limiting groove to reduce the pressure on the lifting belt. At the same time, the slider disengages from the second limiting groove, and the insertion block can be rotated at any time to release the connection state between the lifting belt and the filter plate, simplifying the operation steps and making it more convenient to replace the filter plate.

Detailed implementation manners

[0036] The following further elaborates on the present application in conjunction with the attached Figure 1-8 drawings.

[0037] An embodiment of the present application discloses a lifting filter for separating solid substances in the air. Refer to Figure 1, the lifting filter for separating solid substances in the air includes a frame body 1 and a filter plate 2. The frame body 1 includes a main body 11 and side panels 12 mounted on the main body 11. The side panels 12 are located on one side of the main body 11 in the horizontal direction and at one end of the main body 11 in the length direction. The side panels 12 and the main body 11 are spliced to form a receiving cavity. In actual use, the setting of the side panels 12 can reduce the bending process of the frame body 1, improve production efficiency, and the side panels 12 are small, flexible and convenient to install.

[0038] See Figure 1 , two Z-shaped flange plates 4 are fixed on the main body 11. The two Z-shaped flange plates 4 are respectively located at opposite ends of the main body 11 in the length direction and are vertically arranged, making the installation method of the lifting filter more diversified.

[0039] See Figure 1-2 , a receiving groove 111 is opened on the lower end surface of the main body 11. The filter plate 2 is located in the receiving groove 111 and slides up and down on the main body 11. A rotating shaft 5 is rotated on the main body 11. The rotating shaft 5 is located in the receiving cavity. The rotation axis of the rotating shaft 5 is horizontally arranged and parallel to the length direction of the main body 11. A driving member 6 is fixed on the main body 11. The output shaft of the driving member 6 is fixed to the rotating shaft 5. The driving member 6 drives the rotating shaft 5 to rotate. In this embodiment, the driving member 6 is a motor.

[0040] See Figure 2-5 , two lifting belts 7 are wound on the rotating shaft 5. The two lifting belts 7 are arranged at intervals along the rotation axis of the rotating shaft 5. Each lifting belt 7 includes a belt body 71 and a mounting block 72. The belt body 71 is wound on the rotating shaft 5. The mounting block 72 is fixed to one end of the belt body 71 away from the rotating shaft 5. Mounting grooves 21 are opened on the upper end surface of the filter plate 2. The number and position of the mounting grooves 21 correspond to the number and position of the belt bodies 71 one by one. The mounting grooves 21 are for the corresponding mounting blocks 72 to be inserted. A slot 721 is opened on the outer side wall of the mounting block 72. An insertion block 8 is rotatably connected to the filter plate 2. The insertion block 8 includes a rotating part 81 and an insertion part 82. The rotating part 81 is rotatably connected to the filter plate 2, and the rotation axis of the rotating part 81 is vertically arranged. The upper end surface of the rotating part 81 is flush with the upper end surface of the filter plate 2, and a rectangular groove for a finger to be inserted to twist the rotating part 81 is opened on the upper end surface of the rotating part 81. The insertion part 82 is sleeved on the outside of the rotating part 81 and is fixedly connected to the rotating part 81. The slot 721 is for the insertion part 82 to be inserted.

[0041] In actual use, the mounting block 72 is inserted into the mounting groove 21 so that the insertion part 82 and the slot 721 are aligned, and then the rotating part 81 is rotated so that the insertion part 82 is inserted into the slot 721. By the insertion part 82 abutting against the mounting block 72, the connection between the lifting belt 7 and the filter plate 2 can be realized.

[0042] See Figure 2-6, a limiting plate 9 is lifted and slid within the accommodation groove 111. The limiting plate 9 is located above the filter plate 2. The limiting plate 9 includes a plate body 91 and two bumps 92. Both belt bodies 71 pass through the plate body 91. Grooves 911 are formed at opposite ends of the plate body 91 along the length direction of the main body 11. The grooves 911 penetrate the plate body 91 vertically. Two limiting rods 10 are fixed on the plate body 91. Both limiting rods 10 are located below the plate body 91 and are respectively located on two sides of the two belt bodies 71 away from each other. Each limiting rod 10 passes through and is lifted and slid on the filter plate 2.

[0043] See Figure 2-6 , the positions of the two bumps 92 correspond to the positions of the two grooves 911 one by one. Each bump 92 is located within the corresponding groove 911. Each bump 92 includes a fixing portion 921 and a limiting portion 922. The fixing portion 921 is fixedly connected to the inner wall of the bottom of the corresponding groove 911. A movable block 13 is slidably connected to each fixing portion 921. The movable block 13 is sleeved outside the fixing portion 921 and slides close to or away from the plate body 91, and the sliding direction of the movable block 13 is parallel to the length direction of the main body 11.

[0044] See Figure 2-6 , a relief groove 131 is formed on the outer side wall of the movable block 13 close to the fixing portion 921. The limiting portion 922 is located within the relief groove 131 and is fixedly connected to the fixing portion 921. A clamping groove 132 is formed on the end face of each movable block 13 close to the plate body 91. An elastic member 14 is fixed on each limiting portion 922. The elastic member 14 is located within the relief groove 131 and on the side of the limiting portion 922 close to the plate body 91. The elastic member 14 abuts against the movable block 13, so that the movable block 13 has a tendency to approach the plate body 91. In this embodiment, the elastic member 14 is a spring.

[0045] See Figure 2-7 , a fixing block 15 is fixed on the filter plate 2. The number and positions of the fixing blocks 15 correspond to the number and positions of the movable blocks 13 one by one. The fixing block 15 is located on the side of the clamping groove 132 close to the plate body 91, and the clamping groove 132 is for the fixing block 15 to be inserted into.

[0046] In actual use, when the filter plate 2 descends to disengage from the frame 1, the movable block 13 is moved away from the plate body 91, so that the fixed block 15 disengages from the card slot 132, and the connection state between the limiting plate 9 and the filter plate 2 can be released. When the filter plate 2 is replaced, the plate body 91 is moved to align the fixed block 15 with the card slot 132, and then the movable block 13 is released. The movable block 13 moves close to the plate body 91 under the action of the elastic member 14, so that the fixed block 15 is snapped into the card slot 132, and the connection between the limiting plate 9 and the filter plate 2 can be realized. Through the cooperation between the movable block 13, the elastic member 14 and the fixed block 15, the detachable connection between the limiting plate 9 and the filter plate 2 can be realized without the aid of other tools, making it more convenient to remove the limiting plate 9 from the filter plate 2 or connect the limiting plate 9 to the filter plate 2.

[0047] See Figure 2-8 , a positioning member 16 is fixed on the main body 11. The positioning member 16 is located in the receiving groove 111, and the number and position of the positioning member 16 correspond to the number and position of the movable block 13 one by one. A connecting block 17 is rotatably connected to each movable block 13. The connecting block 17 is located on the side of the movable block 13 away from the plate body 91, and the rotation axis of the connecting block 17 is parallel to the sliding direction of the movable block 13. A threaded groove 171 is formed on the end surface of the connecting block 17 away from the movable block 13, and the threaded groove 171 is used for threaded connection with the positioning member 16. In this embodiment, the positioning member 16 is a positioning block, and the positioning of the limiting plate 9 on the main body 11 can be realized through the threaded cooperation between the positioning member 16 and the connecting block 17.

[0048] See Figure 2-8 , a plurality of first limiting grooves 101 are formed on the outer side wall of each limiting rod 10. The plurality of first limiting grooves 101 are evenly distributed along the sliding direction of the limiting rod 10, and each first limiting groove 101 is arranged around the outer circumference of the limiting rod 10. A slider 18 is slidably connected to the filter plate 2. The number and position of the sliders 18 correspond to the number and position of the limiting rods 10 one by one. Each slider 18 is located on the side of the limiting rod 10 close to the lifting belt 7. Each slider 18 includes a sliding portion 181 and an extending portion 182. The sliding portion 181 is slidably connected to the filter plate 2, and the sliding portion 181 slides close to or away from the limiting rod 10. The sliding direction of the sliding portion 181 is parallel to the sliding direction of the movable block 13, and the first limiting groove 101 is for the sliding portion 181 to be snapped into.

[0049] See Figure 2-8 , a second limiting groove 811 is formed on the outer side wall of the rotating portion 81, and the second limiting groove 811 is for the sliding portion 181 to be snapped into. When the plate body 91 abuts against the filter plate 2, the limiting rod 10 abuts against the sliding portion 181, the sliding portion 181 is snapped into the second limiting groove 811, and the inserting portion 82 is snapped into the inserting slot 721. When the sliding portion 181 is snapped into the first limiting groove 101, the sliding portion 181 disengages from the second limiting groove 811.

[0050] See Figure 2-8 , a third limiting groove 22 is formed in the upper end surface of the filter plate 2. The number and positions of the third limiting grooves 22 correspond one-to-one to the number and positions of the sliding portions 181. Each third limiting groove 22 is located above the corresponding sliding portion 181. The extending portion 182 is located in the third limiting groove 22 and fixedly connected to the sliding portion 181. In actual use, the sliding portion 181 can be driven to move by moving the extending portion 182, making it more convenient to move the moving slider 18.

[0051] In actual use, after the insertion portion 82 is inserted into the slot 721, the extending portion 182 is moved to drive the sliding portion 181 to be inserted into the second limiting groove 811. Then, the limiting plate 9 is connected to the filter plate 2, so that the plate body 91 keeps abutting against the filter plate 2. At this time, the limiting rod 10 abuts against the sliding portion 181, and the sliding portion 181 abuts against the inner wall of the second limiting groove 811, thereby keeping the insertion portion 82 inserted into the slot 721, reducing the situation that the insertion portion 82 disengages from the slot 721, and improving the connection stability between the lifting belt 7 and the filter plate 2.

[0052] When the filter plate 2 is cleaned or replaced, the extending portion 182 is moved to drive the sliding portion 181 to be inserted into the first limiting groove 101. By the sliding portion 181 abutting against the bottom inner wall of the corresponding first limiting groove 101, the limiting plate 9 together with the limiting rod 10 share the pressure exerted by the filter plate 2 on the lifting belt 7. At the same time, the sliding portion 181 disengages from the second limiting groove 811, and the rotating portion 81 can be rotated at any time to release the connection state between the lifting belt 7 and the filter plate 2, simplifying the operation steps and making it more convenient to replace the filter plate 2.

[0053] The implementation principle of a lifting filter for separating solid substances in the air in the embodiment of the present application is as follows:

[0054] When the filter plate 2 descends to disengage from the frame body 1, the filter plate 2 drives the limiting plate 9 to descend. Then, the movable block 13 is moved away from the limiting plate 9, so that the fixed block 15 disengages from the clamping groove 132, releasing the connection state between the limiting plate 9 and the filter plate 2. Then, the plate body 91 is inserted into the receiving groove 111, and the connecting block 17 is twisted so that the positioning member 16 is threadedly connected to the threaded groove 171, realizing the positioning of the limiting plate 9 on the main body 11. At this time, the limiting rod 10 abuts against the filter plate 2 and the plate body 91 abuts against the inner peripheral wall of the receiving groove 111, thereby limiting the filter plate 2, making the lifting belt 7 keep stationary relative to the main body 11, thus reducing the situation that the lifting belt 7 shakes and continuously rubs against the main body 11 to cause wear, being beneficial to extending the service life of the lifting belt 7 and improving the resource utilization rate.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
