Description

Technical Field

[0001] This invention relates to the field of drug decoction processing technology, and in particular to a decoction filtration device for producing cough syrup. Background Technology

[0002] Cough syrups are typically made from a variety of traditional Chinese medicinal herbs, which are decocted with water to extract the active ingredients. During the decoction process, the herbs are extracted at high temperatures for a long time. While the active ingredients dissolve, tissue fragments, small particles, and large molecular impurities such as tannins, proteins, starches, and resins also enter the decoction. The presence of these impurities directly affects the quality of the syrup: on the one hand, insoluble particles cause the syrup to appear cloudy and lack clarity; on the other hand, impurities tend to gradually precipitate during the finished product's storage, affecting product stability and shelf life. In addition, the decoction contains a large amount of colloidal substances with high viscosity. If it is not fully filtered before entering subsequent concentration and dispensing processes, it will not only reduce the purity of the active ingredients but may also clog pipes and equipment. Therefore, the decoction must be filtered after decoction to remove medicinal residues and various non-medicinal impurities, ensuring the clarity and quality of the syrup. For example, existing published documents CN113058306B - A filter device for traditional Chinese medicine liquid and CN223774441U - A filter device for decoction liquid in the production of traditional Chinese medicine cough syrup both disclose a filter device for the decoction liquid after decoction. Although the filter devices in the existing published documents can achieve effective filtration of the decoction liquid, they still have the following shortcomings in actual use: 1. After filtering the medicine for a period of time, the existing filter device will have a certain amount of solid substances such as medicine residue attached to the inside of the filter cartridge. If it is not treated in time, the accumulated solid substances will inevitably affect the subsequent filtration effect. Therefore, in actual use, the staff need to manually clean the filter device regularly, which greatly increases the labor intensity of the staff. In addition, when it is necessary to filter medicines with different components, the staff also need to clean it. 2. In order to reduce the labor intensity of workers, some existing filtration devices are equipped with a cleaning device to assist in cleaning the filter cartridge. However, because the particle size and properties of solid substances such as dregs are different, after the filter cartridge is cleaned by the traditional cleaning device, a certain amount of solid substances are still attached to the inside of the filter cartridge, which affects the subsequent use of the filter cartridge. Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] In view of the problem that the existing filtration devices require regular cleaning by staff, which increases the labor intensity of the staff, a decoction filtration device for the production of cough syrup is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a decoction filtration device for producing cough syrup, comprising: a medicine collection and cleaning mechanism, including an outer protective box and a cavity assembly disposed in the middle of the outer protective box, the cavity assembly dividing the interior of the outer protective box into an upper cleaning chamber and a lower medicine collection chamber, and a vertical partition fixed inside the outer protective box at the cleaning chamber dividing the cleaning chamber into two independent small cleaning chambers; and an adjusting filtration mechanism, including a filtration assembly, a driving assembly, and a liquid inlet assembly; the filtration assembly includes a filter cylinder, a rack plate, a second toothed disc, and a connecting ring, with two filter cylinders symmetrically arranged on the same horizontal plane, when its When one filter cartridge is located in the drug collection chamber, the other is located in the small cleaning chamber. A connecting rod is provided below the filter cartridge along the axial direction, and the connecting rod is rotatably connected to the filter cartridge. An L-shaped plate is fixedly provided in the middle of the connecting rod along the radial direction, and a rack plate is fixedly provided at the other end of the L-shaped plate along the vertical direction. The two rack plates mesh with the same second toothed disc, and a receiving groove for limiting and guiding the rack plate is provided on the vertical partition plate. The cavity assembly includes a transverse partition, an end plate and a first toothed disc. The two symmetrical transverse partitions move in opposite directions along the front and back directions to realize the movement of the filter cartridge between the drug collection chamber and the small cleaning chamber and the separation between the chambers after the movement.

[0006] The beneficial effects of this invention are as follows: When this filtration device is in use, one filter cylinder is located in the medicine collection chamber, while the other is located in the small cleaning chamber. The filter cylinder in the medicine collection chamber is used for filtering the decoction, while the filter cylinder in the small cleaning chamber is used for automatic cleaning. The partition assembly can isolate the medicine collection chamber and the cleaning chamber to achieve simultaneous filtration and cleaning. Through the rotation of the second toothed disc, and in conjunction with the meshing between the second toothed disc and the two toothed plates, the two toothed plates can drive the two filter cylinders to move in opposite directions. In this way, the filter cylinders can be cleaned as needed during the filtration process without stopping the machine, thereby effectively reducing the labor intensity of the workers.

The driving component includes a first electromagnetic plate, a first convex disk, and a third toothed disk. The liquid inlet component includes a second electromagnetic plate, a second convex disk, and a second linkage plate. When one of the filter cylinders is located in the drug collection chamber for drug filtration, the first convex disk and the second convex disk are coaxially arranged at both ends of the filter cylinder and abut against the filter cylinder. A rotating column is coaxially fixed at the end of the first convex disk away from the filter cylinder. The rotating column is slidably sleeved on the side plate of the outer protective box. A ring tooth is arranged circumferentially on the outer wall of the large diameter portion of the first convex disk. A third toothed disk is engaged above the ring tooth. One end of the third toothed disk is fixedly connected to the output shaft of a fourth motor, and the fourth motor is fixedly connected to the outer wall of the outer protective box. A liquid inlet pipe is connected and fixedly arranged at the end of the second convex disk away from the filter cylinder. The liquid inlet pipe is slidably sleeved on the side plate of the outer protective box and extends into the drug collection box.

[0013] In a preferred embodiment of the decoction filtration device for producing cough syrup according to the present invention, a first positioning groove is provided circumferentially on the outer wall of the free end of the rotating column, and a first linkage plate is sleeved on the outer side of the first positioning groove. First guide columns are symmetrically fixed on the outer walls of the outer protective boxes on both sides of the rotating column, and the free ends of the two first guide columns are fixedly connected to the same limiting plate. The first linkage plate is slidably sleeved on the first guide column, and a second spring is slidably sleeved on the first guide column at the position between the outer protective box and the first linkage plate. A spring is fixed on the outer wall of the outer protective box above the rotating column for... A first electromagnetic plate magnetically adsorbs the first linkage plate; a second positioning groove is circumferentially opened on the outer wall of the free end of the liquid inlet pipe, and a second linkage plate is sleeved on the outer side of the second positioning groove; the two ends of the second linkage plate are symmetrically fixed with second guide posts; the other end of the second guide post extends to the outside of the drug collection box and is fixedly connected to the same third linkage plate; a third spring is slidably sleeved on the second guide post at the position between the drug collection box and the third linkage plate; a second electromagnetic plate is fixed on the outer wall of the drug collection box at the position between the two second guide posts; and a third sealing strip is embedded and fixed on the free end of the liquid inlet pipe.

[0014] Given that existing filtration devices are difficult to achieve sufficient and effective cleaning of different fixed substances of medicinal residue, the present invention provides a further optimized and improved decoction filtration device for producing cough syrup, wherein: fixed rings are symmetrically fixed at both ends of the outer wall of the filter cylinder, a connecting ring is rotatably connected to the outer side of one of the fixed rings, and an arc bracket is fitted to the lower outer side of the other fixed ring; a rotating head is fixed at the lower outer side of the connecting ring, and the rotating head is rotatably connected to the front end of the connecting rod, while the rear end of the connecting rod is fixedly connected to the bottom of the arc bracket. An adjustment assembly is provided on the rear side of the small cleaning chamber. The adjustment assembly includes a T-shaped column, a telescopic sleeve, a cylinder, and a first spring. The axis of the T-shaped column is arranged horizontally. The telescopic sleeve is slidably sleeved on the front end of the T-shaped column, and a connecting block is fixedly connected to the rear end of the T-shaped column. An electromagnetic column is fitted and fixedly mounted on the front end of the T-shaped column, and a first spring is slidably sleeved on the T-shaped column between the telescopic sleeve and the connecting block. A cylinder is fixedly mounted on the top surface of the connecting block, and the fixed section of the cylinder is fixedly connected to the inner wall of the outer protective box. On the same horizontal plane, the axes of the filter cartridge and the T-shaped column overlap.

[0015] Another beneficial effect of the present invention is that when the filter cylinder to be cleaned enters the small cleaning chamber during use, the electromagnetic column is de-energized. Under the reset of the first spring, the telescopic sleeve automatically enters the filter cylinder from one end. Then, under the contraction of the cylinder, the telescopic sleeve moves upward to drive the entire filter cylinder to rotate vertically around the rotating head as the axis. In this way, the entire filter cylinder can be kept tilted in the vertical direction. When the filter cylinder is cleaned at this time, the solid matter inside the filter cylinder will be effectively discharged from the tilted lower end of the filter cylinder, thereby avoiding the accumulation of solid matter inside the filter cylinder, which would lead to a reduction in the subsequent filtration quality due to insufficient cleaning.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a decoction filtration device for the production of cough syrup. When the decoction filtration device is in use, the medicine collection and cleaning mechanism 100 mainly includes the functions of collecting the filtered medicine and cleaning the filtered filter cylinder 201a. The adjustment mechanism 200 mainly includes adjusting the position of the filter cylinder 201a as needed and adjusting to maintain effective cleaning.

[0032] Specifically, it includes a drug collection and cleaning mechanism 100, comprising an outer protective box 101 and a cavity assembly 102 disposed in the middle of the outer protective box 101. The cavity assembly 102 divides the interior of the outer protective box 101 into an upper cleaning cavity and a lower drug collection cavity. A vertical partition 101d fixed inside the outer protective box 101 at the cleaning cavity further divides the cleaning cavity into two independent small cleaning cavities. An ultrasonic generator is installed in the vertical partition 101d to generate ultrasonic waves to clean the filter cartridge 201a in the small cleaning cavity. It also includes an adjusting filter mechanism 200, comprising a filter assembly 201, a drive assembly 202, and a liquid inlet assembly 203. A cover 101a is fixedly installed on the top surface of the outer protective box 101, and an inlet pipe 101a-1 and an outlet pipe 101a-2 are fixedly installed on the cover 101a above each small cleaning chamber. A water pump is installed on the outlet pipe 101a-2, and one end of the outlet pipe 101a-2 extends to the lower end of the small cleaning chamber. A medicine collection box 101c is fixedly installed at the lower rear side of the outer protective box 101, and an infusion pipe 101c-1 is fixedly installed in the middle of the outer side wall of the medicine collection box 101c. The infusion pipe 101c-1 is connected to the outlet end of the primary filter. The primary filter mainly realizes the preliminary separation of medicine residue and medicine liquid. The medicine liquid in the medicine collection box 101c is delivered to the two filter cylinders 201a in an selective manner. An outlet pipe 101b is fixedly installed in the middle of the bottom surface of the outer protective box 101. In use, the above-mentioned setup involves injecting cleaning water into the cleaning chamber through the inlet pipe 101a-1, and using an ultrasonic generator to clean the filter cartridge 201a. The cleaning solution is then discharged through the outlet pipe 101a-2, while the decoction enters through the infusion pipe 101c-1 and selectively enters one of the filter cartridges 201a. After being filtered by the filter cartridge 201a, the decoction flows into the lower end of the outer protective box 101 and is finally discharged from the outlet pipe 101b.

[0033] See details Figure 3 , Figure 5 and Figure 6 As shown, the filter assembly 201 includes a filter cylinder 201a, a rack plate 201b, a second rack plate 201c, and a connecting ring 201d. Two filter cylinders 201a are symmetrically arranged on the same horizontal plane. When one filter cylinder 201a is located in the drug collection chamber, the other is located in the small cleaning chamber. A connecting rod 201b-2 is arranged along the axial direction below the filter cylinder 201a, and the connecting rod 201b-2 is rotatably connected to the filter cylinder 201a. An L-shaped plate 201b-1 is fixedly installed in the middle of the connecting rod 201b-2 along the radial direction, and the other part of the L-shaped plate 201b-1... A rack plate 201b is fixedly provided at one end in the vertical direction. Two rack plates 201b mesh with the same second gear plate 201c. A storage groove 101d-1 for limiting and guiding the rack plate 201b is provided on the vertical partition 101d. The second gear plate 201c is fixedly sleeved on the rotating rod 201c-1. The rotating rod 201c-1 is rotatably connected to the vertical partition 101d. One end of the rotating rod 201c-1 extends to the outside of the outer protective box 101 and is embedded in the output end of the third motor 201c-2. The third motor 201c-2 is fixedly connected to the outer wall of the outer protective box 101. In use, the above-mentioned setup utilizes the operation of the third motor 201c-2 to drive the rotating rod 201c-1 to rotate the second gear disk 201c. Since the two sides of the second gear disk 201c are synchronously engaged with rack plates 201b, the rotation of the second gear disk 201c causes the two rack plates 201b to drive the two filter cylinders 201a to move in opposite directions in the vertical direction. Through the forward and reverse rotation of the second gear disk 201c, the two filter cylinders 201a can always be kept in opposite directions, with one in the medicine collection chamber and the other in the cleaning chamber. This allows one filter cylinder 201a to be decocted and filtered in the medicine collection chamber while the other is being cleaned in the cleaning chamber.

[0034] See details Figure 4 , Figure 5 and Figure 8As shown, the cavity assembly 102 includes a transverse partition 102a, an end plate 102b, and a first toothed disc 102c. The two symmetrical transverse partitions 102a move in opposite directions along the front-back direction to realize the movement of the filter cartridge 201a between the drug collection cavity and the small cleaning cavity, as well as the separation between the cavities after the movement. This can prevent the cleaning liquid in the small cleaning cavity from flowing into the drug collection cavity. Example 2

[0035] Reference Figure 4 , Figure 5 and Figure 8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that, in order to better implement the present invention, the specific structure of the filter cylinder 201a moving between the drug collection chamber and the small cleaning chamber, and the separation of the chambers after the movement, is described in detail.

[0036] Specifically, one end of the transverse partition 102a slides through the outer protective box 101 and extends to the outside of the outer protective box 101, where it is fixedly connected to the end plate 102b. One end of the end plate 102b is fixedly provided with a linkage rod 102b-1, and a toothed bar 102b-2 is provided on one side of the linkage rod 102b-1 along the long side direction. The two linkage rods 102b-1 in the same cavity assembly 102 are arranged vertically and parallel to each other. The first toothed disc 102c is located between the two linkage rods 102b-1 and meshes synchronously with the two toothed bars 102b-2. The first toothed disc 102c is fixedly connected to the output shaft of the first motor 102c-1, and the first motor 102c-1 is fixedly connected to the outer wall of the outer protective box 101. A groove 102a-2 is provided in the middle of the side of the two transverse partitions 102a in the same cavity assembly 102, which are close to each other. The groove 102a-2 is provided for the transverse partition 102a to cover the L-shaped plate 201b-1. In use, the first geared disc 102c rotates through the operation of the first motor 102c-1. Since the first geared disc 102c meshes with the rack teeth 102b-2 on the two linkage rods 102b-1, the rotation of the first geared disc 102c causes the two linkage rods 102b-1 to drive the two end plates 102b to move in opposite directions, ultimately achieving the opposite movement of the two transverse partitions 102a. When the two transverse partitions 102a move in opposite directions, they are used for the movement of the filter cartridge 201a between the small cleaning chamber and the drug collection chamber. When the two transverse partitions 102a move in opposite directions, they are used for the separation between the small cleaning chamber and the drug collection chamber after the filter cartridge 201a has moved.

[0037] For further details, please see Figure 8As shown, symmetrical limiting strips 102a-3 are fixed on the left and right sides of the diaphragm 102a. A limiting groove is provided on the inner wall of the outer protective box 101 for clearance fit of the limiting strips 102a-3 to limit and guide the movement of the diaphragm 102a. A first sealing strip 102a-1 is fixed on the side surface of the two diaphragms 102a that are close to each other. The first sealing strip 102a-1 can achieve the sealing between the two diaphragms 102a and the sealing between the diaphragm 102a and the L-shaped plate 201b-1, preventing cleaning water from flowing into the medicine collection chamber. A second sealing strip 102b-3 is fitted and fixed on one side surface of the end plate 102b on the outer side of the diaphragm 102a. The second sealing strip 102b-3 is used to seal the fit between the end plate 102b and the outer protective box 101, preventing cleaning water from overflowing to the outside of the outer protective box 101. Example 3

[0038] Reference Figure 2 , Figure 4 , Figure 5 and Figure 9 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that, in order to avoid the waste of medicine due to insufficient filtration caused by viscosity and adsorption issues during filtration, and to fully realize the technology of delivering the medicine in the medicine collection box 101c to the two filter cartridges 201a in an selective manner, this embodiment is proposed.

[0039] Specifically, the drive assembly 202 and the liquid inlet assembly 203 are located on the front and rear sides of the drug collection chamber, respectively. The drive assembly 202 includes a first electromagnetic plate 202a, a first convex disk 202b, and a third toothed disk 202c. The liquid inlet assembly 203 includes a second electromagnetic plate 203a, a second convex disk 203b, and a second linkage plate 203c. When one of the filter cartridges 201a is located in the drug collection chamber for drug filtration, the first convex disk 202b and the second convex disk 203b are coaxially arranged at both ends of the filter cartridge 201a and abut against the filter cartridge 201a. A rotating column 202b is coaxially fixed at the end of the first convex disk 202b away from the filter cartridge 201a. 2. The rotating column 202b-2 is slidably sleeved on the side plate of the outer protective box 101. The outer wall of the large diameter part of the first convex disk 202b is provided with ring teeth 202b-1 along the circumferential direction. A third toothed disk 202c is meshed above the ring teeth 202b-1. One end of the third toothed disk 202c is fixedly connected to the output shaft of the fourth motor 202c-1, and the fourth motor 202c-1 is fixedly connected to the outer wall of the outer protective box 101. The end of the second convex disk 203b away from the filter cylinder 201a is connected to and fixedly provided with an inlet pipe 203b-1, and the inlet pipe 203b-1 is slidably sleeved on the side plate of the outer protective box 101 and extends into the medicine box 101c. In use, the decoction entering the medicine collection box 101c enters one of the filter cylinders 201a through the inlet pipe 203b-1. After the decoction enters the filter cylinder 201a, the operation of the fourth motor 202c-1 drives the third toothed disc 202c to rotate. Due to the meshing between the third toothed disc 202c and the ring tooth 202b-1, the rotation of the third toothed disc 202c can drive the first convex disc 202b to rotate the filter cylinder 201a. Under the action of centrifugal force, the decoction in the filter cylinder 201a can be fully filtered, thereby avoiding the problem of insufficient filtration.

[0040] A first positioning groove 202b-3 is provided circumferentially on the outer wall of the free end of the rotating column 202b-2, and a first linkage plate 202e is sleeved on the outer side of the first positioning groove 202b-3. In this way, the rotating column 202b-2 can move along the axial direction while maintaining free rotation. First guide columns 202d are symmetrically fixed on the outer walls of the outer protective boxes 101 on both sides of the rotating column 202b-2, and the free ends of the two first guide columns 202d are fixedly connected. On the same limiting plate, the first linkage plate 202e is slidably sleeved on the first guide post 202d, and a second spring 202d-1 is slidably sleeved on the first guide post 202d at the position between the outer protective box 101 and the first linkage plate 202e. The second spring 202d-1 is set to realize the reset of the first convex disk 202b. A first electromagnetic plate 202a for magnetic adsorption of the first linkage plate 202e is fixed on the outer wall of the outer protective box 101 above the rotating post 202b-2. A second positioning groove 203b-2 is circumferentially formed on the outer wall of the free end of the inlet pipe 203b-1, and a second linkage plate 203c is sleeved on the outer side of the second positioning groove 203b-2. This allows the inlet pipe 203b-1 to move along its axis while maintaining free rotation. Second guide posts 203c-1 are symmetrically fixed at both ends of the second linkage plate 203c. The other end of the second guide post 203c-1 extends to the outside of the drug collection box 101c and is fixedly connected to the same third linkage plate 203c-2. The drug collection box 101c and the third linkage plate... A third spring 203c-3 is slidably sleeved on the second guide post 203c-1 located between 203c-2. The setting of the third spring 203c-3 can realize the reset of the second convex disk 203b. A second electromagnetic plate 203a is fixed on the outer wall of the drug collection box 101c located between the two second guide posts 203c-1. A third sealing strip is embedded and fixed on the free end of the liquid inlet pipe 203b-1. Thus, under the reset of the third spring 203c-3, one end of the liquid inlet pipe 203b-1 abuts against the inner wall of the drug collection box 101c to realize the isolation of the liquid inlet pipe 203b-1. In use, after the filter cartridge 201a moves to the predetermined position in the drug collection chamber, the first electromagnetic plate 202a and the second electromagnetic plate 203a are simultaneously energized to generate magnetism. Under the action of magnetic attraction, the first electromagnetic plate 202a drives the first convex disk 202b to move towards the filter cartridge 201a by attracting the first linkage plate 202e, and the second electromagnetic plate 203a drives the second convex disk 203b towards the filter cartridge 201a by attracting the third linkage plate 203c-2. Lateral movement ultimately allows the first convex disk 202b and the second convex disk 203b to abut against both ends of the filter cylinder 201a, enabling the decoction to enter the filter cylinder 201a for filtration. When the first electromagnetic plate 202a and the second electromagnetic plate 203a are simultaneously de-energized, the first convex disk 202b and the second convex disk 203b are separated from the filter cylinder 201a under the reset of the second spring 202d-1 and the third spring 203c-3, facilitating the movement of the filter cylinder 201a. Example 4

[0041] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 This is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in order to ensure that the inside of the filter cartridge 201a can be thoroughly and effectively cleaned during the cleaning process, this embodiment is proposed.

[0042] Specifically, the outer walls of the filter cartridge 201a are symmetrically fixed with two fixing rings 201a-1 at both ends. One of the fixing rings 201a-1 is rotatably connected to a connecting ring 201d, thus allowing the filter cartridge 201a to rotate freely relative to the connecting ring 201d. The lower outer end of the other fixing ring 201a-1 is fitted with an arc bracket 201b-3. The lower outer wall of the connecting ring 201d is fixed with a rotating head 201d-1, which is rotatably connected to the front end of the connecting rod 201b-2. At the same time, the rear end of the connecting rod 201b-2 is fixedly connected to the bottom of the arc bracket 201b-3. An adjusting assembly 103 is provided on the rear side of the small cleaning chamber. The adjusting assembly 103 includes a T-shaped column 103a, a telescopic sleeve 103b, and a cylinder. 103c and the first spring 103d, the axis of the T-shaped column 103a is arranged in the horizontal direction, the front end of the T-shaped column 103a is slidably sleeved with the telescopic sleeve 103b, and the rear end of the T-shaped column 103a is fixedly connected with the connecting block 103a-2. The front end of the T-shaped column 103a is fitted and fixedly provided with the electromagnetic column 103a-1, and the first spring 103d is slidably sleeved on the T-shaped column 103a at the position between the telescopic sleeve 103b and the connecting block 103a-2. The setting of the first spring 103d can realize the reset of the telescopic sleeve 103b. The top surface of the connecting block 103a-2 is fixedly provided with the cylinder 103c, and the fixed section of the cylinder 103c is fixedly connected to the inner wall of the outer protective box 101. On the same horizontal plane, the axes of the filter cylinder 201a and the T-shaped column 103a overlap. In use, after the filter cylinder 201a moves into the small cleaning chamber, the power to the electromagnetic column 103a-1 is cut off, and the telescopic sleeve 103b moves laterally into the filter cylinder 201a under the reset of the first spring 103d. Then, the cylinder 103c extends and retracts to drive the T-shaped column 103a to move upward. Driven by the telescopic sleeve 103b, one end of the filter cylinder 201a is adjusted vertically with the rotating head 201d-1 as the axis. At this time, the entire filter cylinder 201a to be cleaned is tilted in the vertical direction, which facilitates the discharge of solid matter inside the filter cylinder 201a.

[0043] Furthermore, a retaining ring 201a-2 with a right-angled trapezoidal cross-section is fixed circumferentially on the inner wall of the filter cylinder 201a at the fixing ring 201a-1, and the inclined surface of the trapezoid is located near the center of the filter cylinder 201a. When the filter cylinder 201a is in a horizontal state, the retaining ring 201a-2 can intercept solid substances and prevent solid substances from falling into the collection chamber during filtration. When the filter cylinder 201a is in an inclined position, the inclined surface can effectively remove solid substances inside the filter cylinder 201a. Limiting holes 201a-3 are arranged in a circumferential array on one end face of the retaining ring 201a-2. Inserts for clearance matching with the limiting holes 201a-3 are fixed on one end face of the first convex disk 202b and the second convex disk 203b. This arrangement can achieve limiting matching between the first convex disk 202b and the second convex disk 203b and the filter cylinder 201a.
