Technical Field

[0001] This utility model relates to the field of chemical conveying technology, specifically to a chemical conveying device with a filtration structure. Background Technology

[0002] A chemical conveying device with a filtration structure is a specialized piece of equipment that integrates fluid conveying and impurity filtration functions. Its core function is to simultaneously remove solid impurities, colloidal particles, or incompatible trace contaminants that may be present in the chemicals during the process of conveying various chemicals from storage containers to the target workstation, thereby ensuring smooth conveying system operation, safety of downstream equipment, and chemical purity that meets process requirements.

[0003] Current chemical conveying devices with filtration structures lack a self-cleaning mechanism, making the filtration structure prone to clogging due to impurities. This results in short filtration cycles and frequent shutdowns for disassembly and replacement of filter components, thus affecting chemical conveying efficiency.

[0004] Therefore, chemical delivery devices with filtration structures are needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a chemical delivery device with a filtration structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chemical conveying device with a filter structure, including a support, a first conveying pipe at the top of the support, a filter pipe connected to the end of the first conveying pipe, and a second conveying pipe connected to the end of the filter pipe away from the first conveying pipe.

[0007] The disassembly and assembly unit is located inside the filter tube. The disassembly and assembly unit includes a filter assembly and a disassembly and assembly component. The filter assembly includes a filter cylinder, which is used to filter impurities in the conveyed chemicals. The disassembly and assembly component is used to quickly disassemble and assemble the filter cylinder inside the filter tube.

[0008] A cleaning unit is located inside the filter tube. The cleaning unit includes a vibration component and a cleaning component. The cleaning component includes a rotating frame and a brush. When the rotating frame rotates, it works with the vibration component to vibrate the brush in the cleaning component. The brush is fixedly installed on the inner side of the rotating frame and is used to clean the outer wall of the filter cartridge. When conveying chemicals, they are conveyed to the filter tube through the first conveying pipe. Under the restriction of the disassembly and assembly unit, impurities in the chemicals can be filtered, and the disassembly and assembly unit allows for quick disassembly and replacement of the filter cartridge. Under the restriction of the cleaning unit, impurities attached to the outer wall of the filter cartridge can be cleaned, preventing the filter holes inside the filter cartridge from becoming clogged. The cleaning unit can also achieve a self-cleaning effect. The filtered chemicals are then conveyed to the second conveying pipe, thus completing the chemical conveying operation.

[0009] Preferably, the cleaning unit includes a fixed frame fixedly installed on the inner wall of the filter tube, a waterproof shell fixedly installed on the side wall of the fixed frame, a motor fixedly installed inside the waterproof shell, a rotating sleeve fixedly installed at the output end of the motor, a first magnetic block fixedly installed on the inner wall of the rotating sleeve, a shaped block slidably arranged inside the rotating sleeve, a second magnetic block fixedly installed on the side wall of the shaped block, a rotating rod fixedly installed on the side of the shaped block away from the second magnetic block, a sealing ring fixedly installed at the end of the waterproof shell, a rotating frame fixedly installed at the end of the rotating rod away from the shaped block, and a protrusion provided at the end of the rotating frame.

[0010] Preferably, the outer wall of the irregular block is multi-toothed, and the irregular block is adapted to slide with the rotating sleeve. Under its restriction, the rotating sleeve can drive the irregular block to rotate, and the irregular block can slide inside the rotating sleeve.

[0011] Preferably, the sealing ring is made of rubber, and the inner side of the sealing ring is rotatably connected to the outer wall of the rotating rod. Under the restriction of the sealing ring, chemicals can be prevented from seeping into the interior of the waterproof shell.

[0012] Preferably, the end of the rotating frame is arc-shaped, and the outer wall of the protrusion is arc-shaped. When the rotating frame and the protrusion slide and press, the rotating frame drives the irregular block to slide into the rotating sleeve through the rotating rod.

[0013] Preferably, the disassembly and assembly unit includes an installation plate sleeved inside the filter tube, a filter cylinder is fixedly installed on the side wall of the installation plate, and a slot is provided on the outer wall of the installation plate.

[0014] Preferably, the inner wall of the filter tube is provided with a sliding groove, a third magnetic block is fixedly installed on the inner wall of the sliding groove, a fourth magnetic block is slidably arranged inside the sliding groove, and a locking pin is fixedly installed on the side wall of the fourth magnetic block.

[0015] Preferably, the mounting plate is fixedly installed on the side away from the slot and on the side closer to the protrusion, and the mounting plate is slidably disposed on the side closer to the protrusion and at the end of the rotating frame. With the support of the mounting plate, the rotating frame rotates and slides and presses against the protrusion, causing the rotating frame to move in the direction of the motor.

[0016] Preferably, the third magnetic block and the fourth magnetic block are magnetically repulsive, and the locking pin engages with the slot. Under the restriction of magnetic repulsion, the third magnetic block can push the fourth magnetic block and the locking pin, so that the locking pin engages with the slot.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This chemical conveying device with a filtration structure comprises a cleaning unit as one component. During chemical conveying, the filter cartridge of the disassembled unit is responsible for filtration. To prevent impurities from clogging the filter cartridge, after the motor is started, its output end rotating sleeve rotates, driving the rotating rod, rotating frame, and brush to rotate via a matching multi-toothed irregularly shaped block. Because the brush adheres to the outer wall of the filter cartridge, it cleans the cartridge. When the rotating frame rotates, its end presses against the protrusion, causing the rotating rod, irregularly shaped block, and second magnetic block to slide into the rotating sleeve. After the pressing is complete, the second magnetic block and the first magnetic block repel each other magnetically, pushing the irregularly shaped block back to its original position, causing the brush to vibrate reciprocally, preventing impurities from adhering to itself. This cleans both the filter cartridge and the brush itself, improving conveying efficiency.

[0019] 2. This chemical conveying device with a filtration structure consists of a disassembly and assembly unit, with the filter cartridge performing chemical filtration. To replace an old filter cartridge, first remove the bolts connecting the filter tube to the first and second conveying pipes and take out the filter tube. Then, press the locking pin to disengage it from the slot, allowing you to remove the mounting plate and filter cartridge. When installing a new filter cartridge, after aligning the slot and locking pin, the third and fourth magnetic blocks repel each other, pushing the locking pin to engage with the slot, quickly completing the disassembly and assembly.

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a chemical conveying device with a filter structure, including a support 1, a first conveying pipe 2 at the top of the support 1, a filter pipe 3 connected to the end of the first conveying pipe 2, and a second conveying pipe 4 connected to the end of the filter pipe 3 away from the first conveying pipe 2.

[0030] The disassembly and assembly unit 6 is located inside the filter tube 3. The disassembly and assembly unit 6 includes a filter assembly and a disassembly and assembly assembly. The filter assembly includes a filter cylinder 62, which is used to filter impurities in the conveyed chemicals. The disassembly and assembly assembly assembly is used to quickly disassemble and assemble the filter cylinder 62 inside the filter tube 3.

[0031] Cleaning unit 5 is located inside filter tube 3. Cleaning unit 5 includes a vibration component and a cleaning component. The cleaning component includes a rotating frame 510 and a brush 511. When the rotating frame 510 rotates, it works with the vibration component to vibrate the brush 511 in the cleaning component. The brush 511 is fixedly installed on the inner side of the rotating frame 510. The brush 511 is used to clean the outer wall of filter cylinder 62.

[0032] In use, when transporting chemicals, they are conveyed to the filter tube 3 through the first conveying pipe 2. Under the restriction of the disassembly and assembly unit 6, impurities in the chemicals can be filtered out. The disassembly and assembly unit 6 can quickly disassemble and replace the filter cartridge 62. Under the restriction of the cleaning unit 5, impurities attached to the outer wall of the filter cartridge 62 can be cleaned to prevent the filter holes inside the filter cartridge 62 from becoming clogged. The cleaning unit 5 can also achieve a self-cleaning effect. The filtered chemicals are then conveyed to the second conveying pipe 4 to complete the chemical transport work.

[0033] Example 2

[0034] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as detailed below:

[0035] The cleaning unit 5 includes a mounting bracket 51 fixedly installed on the inner wall of the filter tube 3. A waterproof shell 52 is fixedly installed on the side wall of the mounting bracket 51. A motor 53 is fixedly installed inside the waterproof shell 52. A rotating sleeve 54 is fixedly installed at the output end of the motor 53. A first magnetic block 55 is fixedly installed on the inner wall of the rotating sleeve 54. A shaped block 56 is slidably arranged inside the rotating sleeve 54. A second magnetic block 57 is fixedly installed on the side wall of the shaped block 56. A rotating rod 58 is fixedly installed on the side of the shaped block 56 away from the second magnetic block 57. A sealing ring 59 is fixedly installed at the end of the waterproof shell 52. A rotating frame 510 is fixedly installed at the end of the rotating rod 58 away from the shaped block 56. A protrusion 512 is provided at the end of the rotating frame 510.

[0036] The outer wall of the irregular block 56 is multi-toothed. The irregular block 56 is adapted to slide with the rotating sleeve 54. Under its restriction, the rotating sleeve 54 can drive the irregular block 56 to rotate, and the irregular block 56 can slide inside the rotating sleeve 54.

[0037] The sealing ring 59 is made of rubber and is rotatably connected to the outer wall of the rotating rod 58. Under the restriction of the sealing ring 59, chemicals can be prevented from seeping into the interior of the waterproof shell 52.

[0038] The rotating frame 510 has an arc-shaped end and the outer wall of the protrusion 512 has an arc-shaped outer wall. When the rotating frame 510 and the protrusion 512 slide and press, the rotating frame 510 drives the irregular block 56 to slide into the rotating sleeve 54 through the rotating rod 58.

[0039] In use, when transporting chemicals, filtration and transport can be achieved through the filter cartridge 62 in the disassembly and assembly unit 6. During filtration in the filter cartridge 62, to prevent impurities from clogging the filter cartridge 62, the impurities attached to the outer wall of the filter cartridge 62 need to be cleaned. At this time, the motor 53 is started, and the rotating sleeve 54 fixedly installed at its output end rotates accordingly. Since the irregular block 56 is multi-toothed and adapts to slide with the rotating sleeve 54, under its constraint, the rotating sleeve 54 can drive the irregular block 56 to rotate. The irregular block 56 drives the rotating rod 58 to rotate, and the rotating rod 58 drives the rotating frame 510 and the brush 511 to rotate. Since the brush 511 is in close contact with the outer wall of the filter cartridge 62, the rotating brush 511 can clean the filter cartridge 62 under its constraint. When the rotating frame 510 rotates, its end slides and presses against the protrusion 512, causing the rotating frame 510 to drive the rotating rod 58 towards the motor 53. The rotating rod 58 drives the irregular block 56 and the second magnetic block 57 to slide into the rotating sleeve 54. When the rotating frame 510 no longer presses against the protrusion 512, the irregular block 56 is reset and pushed back by the magnetic repulsion between the second magnetic block 57 and the first magnetic block 55, causing the brush 511 to vibrate repeatedly, preventing impurities from adhering to the inside of the brush 511. This structure can achieve cleaning of the filter cartridge 62 and self-cleaning effect of the brush 511, thereby improving the efficiency of chemical delivery.

[0040] Example 3

[0041] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0042] The disassembly and assembly unit 6 includes a mounting plate 61 fitted inside the filter tube 3. A filter cylinder 62 is fixedly installed on the side wall of the mounting plate 61. A slot 63 is opened on the outer wall of the mounting plate 61. A sliding groove 64 is opened on the inner wall of the filter tube 3. A third magnetic block 65 is fixedly installed on the inner wall of the sliding groove 64. A fourth magnetic block 66 is slidably arranged inside the sliding groove 64. A locking pin 67 is fixedly installed on the side wall of the fourth magnetic block 66.

[0043] The mounting plate 61 is fixedly installed on the side away from the slot 63 and the protrusion 512. The side of the mounting plate 61 close to the protrusion 512 is slidably set at the end of the rotating frame 510. Under the support of the mounting plate 61, the rotating frame 510 rotates and slides and presses against the protrusion 512, causing the rotating frame 510 to move towards the motor 53.

[0044] Among them, the third magnetic block 65 and the fourth magnetic block 66 are magnetically repulsive, and the locking pin 67 is engaged with the locking slot 63. Under the restriction of magnetic repulsion, the third magnetic block 65 can push the fourth magnetic block 66 and the locking pin 67, so that the locking pin 67 is engaged with the locking slot 63.

[0045] When filtering conveyed chemicals, the filter cartridge 62 achieves the filtration effect. When the filter cartridge 62 has been used for a long time, it needs to be replaced. To do this, loosen the bolts connecting the filter tube 3 to the first conveying tube 2 and the second conveying tube 4, remove the filter tube 3, press the locking pin 67 so that it is no longer engaged with the locking groove 63, and then remove the mounting plate 61 and the filter cartridge 62 from inside the filter tube 3 for replacement. Install the new filter cartridge 62 inside the filter tube 3. When the locking groove 63 and the locking pin 67 are aligned, the locking pin 67 can be pushed under the magnetic repulsion of the third magnetic block 65 and the fourth magnetic block 66, causing the locking pin 67 to engage with the locking groove 63, thus quickly completing the installation and removal of the filter cartridge 62.

[0046] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above.

Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
