Description

Technical Field

[0001] This utility model relates to the field of candle-type cylindrical filter technology, and more specifically, to a candle-type cylindrical filter cloth that can automatically break the cake during cake removal. Background Technology

[0002] The candle filter cartridge is the core component of a candle filter, typically made of stainless steel, plastic, or ceramic, and shaped like a candle. The surface of the cartridge is covered with filter cloth or has a microporous structure, increasing the filtration area and improving filtration efficiency. The cartridge traps solid particles in the liquid through its surface filter cloth, forming a filter cake layer, thus achieving solid-liquid separation. As filtration progresses, the filter cake layer gradually thickens, increasing the resistance of the filtrate through it and reducing filtration efficiency. The main purpose of decakering in candle filters is to remove the filter cake layer and restore the cartridge's filtration performance. When the filter cake layer reaches a certain thickness, causing a decrease in filtration efficiency, it needs to be removed through backflushing. After decakering, the cartridge can rebuild a new filter cake layer, starting a new filtration cycle. This process not only ensures filtration efficiency but also extends the lifespan of the cartridge and reduces the cost of filtration consumables. Furthermore, decakering typically uses gas backflushing, resulting in clean and rapid slag removal, adapting to various viscous materials, further enhancing the automation and applicability of candle filters.

[0003] For example, the existing publication number CN201020317Y discloses a new type of candle filter, including a filter tank, which includes a tank top, a mounting plate, and a tank body. The tank top, mounting plate, and tank body are connected by bolts. The filter candle column is mounted on the mounting plate with fixing bolts. There is a discharge pipe on the tank top, a feed pipe and a drain port at the bottom of the tank body, a manhole sight glass is installed on the tank body wall, a butterfly valve is installed on the drain port, and a pressure reducing nozzle is installed at the inlet end of the feed pipe. The pressure reducing nozzle has a double-layer cylindrical structure and a nozzle is opened on the cylindrical wall of the pressure reducing nozzle.

[0004] The proposed novel candle filter relies on liquid fluctuations to flush the filter cake when the drain butterfly valve is opened. This method cannot effectively break up dense or sticky filter cakes, and can easily lead to residue residue after discharge. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a candle-shaped cylindrical filter cloth that can automatically break up the filter cake during the cake removal process. This solves the problem that the prior art relies on the liquid fluctuations when the drain butterfly valve is opened to wash the filter cake, which cannot effectively break up dense or sticky filter cakes and easily leads to residue in the discharge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a candle-shaped cylindrical filter cloth that can automatically break up filter cakes during cake removal, comprising a filter cylinder assembly and a candle-shaped filter seat installed at the top of the filter cylinder assembly. The filter cylinder assembly includes a filter cylinder body, and a cover is fixedly connected to the outside of the filter cylinder body. A cake-breaking component is provided on the filter cylinder body and the cover. The cake-breaking component includes an air inlet pipe, which is fixedly connected to the cover, and one end of the air inlet pipe is placed inside the candle-shaped filter seat. The cake-breaking component also includes a ring seat disposed inside the filter cylinder body and capable of rotating as the airflow passes through the air in the air inlet pipe. The cake-breaking component also includes a cake-breaking cutter that is fixedly connected in a ring shape inside the ring seat and can synchronously break up the fallen filter cakes as the ring seat rotates.

[0007] Preferably, the biscuit breaking assembly further includes a manifold, which is fixedly connected to the middle of the air intake pipe and is in communication with the air intake pipe.

[0008] Preferably, the cake-breaking assembly further includes a horizontal rotating shaft, which is rotatably connected to the inner side of the manifold, and the cake-breaking assembly further includes fan blades, which are fixedly connected to the outer side of the horizontal rotating shaft.

[0009] Preferably, the biscuit breaking assembly further includes a first conical tooth, which is fixedly connected to one end of the horizontal rotating shaft.

[0010] Preferably, the cake-breaking assembly further includes a vertical rotating shaft, which is rotatably connected to the inner side of the cover. A second conical tooth is fixedly connected to the bottom of the vertical rotating shaft. The second conical tooth contacts and is meshed with the first conical tooth. The cake-breaking assembly also includes a toothed disc, which is fixedly connected to the top of the vertical rotating shaft.

[0011] Preferably, the cake-breaking assembly further includes a toothed groove group, which is distributed in a ring shape on the outer middle of the ring seat. The toothed groove group is in contact with the toothed disc and is meshed and rotatably connected. The cake-breaking assembly also includes a ball bearing, which is rotatably connected in a ring shape on the outer side of the ring seat. The ball bearing is in contact with the rail groove on the inner wall of the filter cartridge body.

[0012] Preferably, the filter cartridge assembly further includes a feed pipe fixedly connected to the outside of the filter cartridge body, and the filter cartridge assembly further includes a discharge pipe fixedly connected to the top of the filter cartridge body.

[0013] Preferably, the filter cartridge assembly further includes a discharge valve, which is fixedly connected to the bottom of the filter cartridge body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] I. Integrated automatic cake breaking function

[0016] This patent utilizes an airflow-driven cake-breaking assembly, including fan blades, a conical gear transmission, and a rotating cutter, to actively break up the filter cake during the cake removal process. In contrast, the prior art relies on liquid fluctuations during drainage to passively clean the filter cake. This design achieves forced cake breaking through mechanical cutting, making it particularly suitable for highly viscous or severely agglomerated filter cakes, significantly improving cake removal efficiency.

[0017] II. Optimization of Transmission Structure Linkage

[0018] Utilizing the kinetic energy of the airflow from the intake pipe, a multi-stage transmission system—horizontal rotating shaft-conical teeth / vertical rotating shaft-toothed disc—converts the airflow energy into the rotational power of the ring seat, driving the cake-cutter. While the previous design lacked an energy recovery mechanism, this design achieves dual utilization of the air source in both the cake-removing and crushing actions, improving system energy efficiency.

The cake breaking assembly 2 also includes a cake breaking cutter 231 that is fixedly connected in a ring shape inside the ring seat 23 and can rotate with the ring seat 23 to break up the fallen filter cake synchronously.

[0026] This patented design, which combines mechanical transmission with active cutting, solves the problems of incomplete cake removal and reliance on manual operation in traditional candle filters. It achieves efficient cake crushing and automated slag discharge, significantly improving the reliability and operating efficiency of the filtration system.

[0027] The disc breaking assembly 2 also includes a manifold 211, which is fixedly connected to the middle of the air intake pipe 21 and is connected to the air intake pipe 21.

[0028] The breaker assembly 2 also includes a horizontal rotating shaft 22, which is rotatably connected to the inner side of the busbar 211. The breaker assembly 2 also includes a fan blade 221, which is fixedly connected to the outer side of the horizontal rotating shaft 22.

[0029] The biscuit breaking component 2 also includes a first conical tooth 222, which is fixedly connected to one end of the horizontal rotating shaft 22.

[0030] The biscuit breaking assembly 2 also includes a vertical rotating shaft 24, which is rotatably connected to the inside of the cover 15. A second conical tooth 241 is fixedly connected to the bottom of the vertical rotating shaft 24. The second conical tooth 241 is in contact with and meshes with the first conical tooth 222. The biscuit breaking assembly 2 also includes a toothed disc 242, which is fixedly connected to the top of the vertical rotating shaft 24.

[0031] The cake breaking assembly 2 also includes a toothed groove group 232, which is distributed in a ring on the outer middle of the ring seat 23. The toothed groove group 232 is in contact with the toothed disc 242 and is meshed and rotatably connected. The cake breaking assembly 2 also includes a ball bearing 233, which is rotatably connected in a ring on the outer side of the ring seat 23. The ball bearing 233 is in contact with the inner wall groove of the filter cartridge body 11.

[0032] The filter cartridge assembly 1 also includes a feed pipe 12, which is fixedly connected to the outside of the filter cartridge body 11. The filter cartridge assembly 1 also includes a discharge pipe 13, which is fixedly connected to the top of the filter cartridge body 11.

[0033] The filter cartridge assembly 1 also includes a discharge valve 14, which is fixedly connected to the bottom of the filter cartridge body 11.

[0034] Working principle:

[0035] When using the filter cartridge assembly 1 and the candle filter seat 3 for filtration, the external medium is first introduced into the filter cartridge body 11 through the feed pipe 12. At this time, the medium is permeated and filtered from the outside to the inside of the candle filter seat 3. Then, the medium is discharged through the discharge pipe 13 after filtration.

[0036] At this time, filter cake left after filtration will remain on the outside of the candle filter holder 3;

[0037] When removing the filter cake remaining on the outside of the candle filter holder 3, an external air pump can be connected to the lower end of the air inlet pipe 21. The air pump blows air into the air inlet pipe 21. At this time, the gas will enter the filter cartridge body 11 through the air inlet pipe 21 and blow air from the inside of the candle filter holder 3 to the outside. At this time, the filter cake remaining on the outside of the candle filter holder 3 begins to fall downward due to the airflow.

[0038] Specifically, when the airflow passes through the manifold 211 in the intake pipe 21, it blows the fan blades 221. At this time, the horizontal rotating shaft 22 and the first conical tooth 222 fixed inside the fan blades 221 begin to rotate. Under the meshing action of the first conical tooth 222 and the second conical tooth 241, the vertical rotating shaft 24 inside the second conical tooth 241 drives the toothed disc 242 to rotate. The ring seat 23 will start to rotate synchronously inside the filter cartridge body 11 under the meshing action of the toothed disc 242 and the tooth groove group 232. At this time, the cake-breaking cutter 231 fixed inside the ring seat 23 will rotate and complete the crushing work of the fallen filter cake.

[0039] Finally, the crushed filter cake will accumulate at the discharge valve 14, and the staff can remove the crushed filter cake from the filter cartridge body 11 by opening and closing the discharge valve 14.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
