Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a slag discharge mechanism for a filter. Background Technology

[0002] Existing filters generally consist of a tank and a filter cylinder installed inside the tank. The filter cylinder has an oil inlet, the tank has an oil outlet, and the bottom of the tank has a slag discharge port. In use, the material enters the filter cylinder through the oil inlet, is filtered by the filter cylinder, and is discharged from the tank through the oil outlet. Impurities in the material are isolated by the mesh on the surface of the filter cylinder, thus achieving a filtration effect. However, over time, the mesh will gradually become clogged by waste residue, causing a decrease in the permeability of the filter cylinder and affecting the filtration efficiency.

[0003] To address this technical problem, Chinese utility model patent CN208389504U discloses an improved continuous automatic slag discharge filter. This solution uses a drive motor and planetary gear structure to drive the roller brush to rotate on its own axis while revolving around the central axis, allowing the roller brush to fully contact the filter screen when cleaning it, thus enhancing the brushing effect.

[0004] While the above-mentioned technical solutions can improve the cleaning effect on the filter cylinder, the roller brush rotates on its own axis while revolving around the central axis, causing the cleaned waste to move irregularly inside the filter cylinder with a relatively high initial velocity. This waste is very likely to re-enter the mesh of the filter cylinder, causing the areas that have been cleared to become clogged again, thus affecting the cleaning effect. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a slag discharge mechanism for a filter to solve the technical problem that the waste residue moves irregularly when cleaning the filter cylinder of the existing filter, which easily causes secondary clogging of the filter cylinder.

[0006] To achieve the above objectives, this utility model provides a slag discharge mechanism for a filter, comprising a filter, wherein the filter includes:

[0007] A tank with a slag discharge port;

[0008] A filter screen cylinder is installed in the tank, and the bottom of the filter screen cylinder forms an opening that communicates with the slag discharge port;

[0009] A cleaning assembly for cleaning the mesh of the filter cylinder, the cleaning assembly including a cleaning brush and a drive structure for driving the cleaning brush to move relative to the filter cylinder;

[0010] The cover is used to enclose the cleaning brush. The cover extends along the length of the cleaning brush and has a slag outlet at the bottom that connects to the slag discharge port. One end of the cover is open and fits into the filter screen cylinder to form a semi-enclosed cleaning area. The cover can move synchronously with the cleaning brush so that the waste only moves inside the cover, thereby preventing the waste from flying into the outside of the cleaning area.

[0011] As a preferred embodiment of this utility model, the filter further includes:

[0012] A can lid is provided at the upper opening of the can body, the can lid has a feed inlet, and a discharge outlet is provided on one side of the can body;

[0013] A baffle plate is provided in the tank body to block the opening at the bottom of the filter screen cylinder. There is a gap between the baffle plate and the slag outlet at the bottom of the cover body. The baffle plate has a through hole that is connected to the slag discharge port.

[0014] As a preferred embodiment of this utility model, the driving structure includes:

[0015] A drive motor is located at the upper end of the can lid;

[0016] The bracket located at the lower end of the can lid is rotated. The bracket is connected to the output shaft of the drive motor, the bracket is connected to the cleaning brush, and the bracket is fixedly connected to the cover.

[0017] As a preferred technical solution of this utility model, the upper end of the cleaning brush is provided with a connecting shaft, the connecting shaft passes through a through groove opened at the upper end of the cover, the connecting shaft is rotatably connected to the bracket, and the connecting shaft is connected to a gear, the gear meshing with an annular rack provided in the can lid.

[0018] As a preferred technical solution of this utility model, scraping components for scraping off waste residue are provided on both sides of the cover.

[0019] As a preferred embodiment of this utility model, the scraping component includes a scraper disposed on the side of the cover.

[0020] As a preferred embodiment of this utility model, a mounting base is provided on the side of the cover, the mounting base is rotatably connected to the end shafts located at both ends of the scraper, and a spring is provided between the cover and the scraper to keep the scraper in contact with the filter cylinder.

[0021] As a preferred technical solution of this utility model, the surface of the scraper is provided with a plurality of hollow grooves.

[0022] The beneficial effects of this utility model are as follows: This utility model can prevent the irregular movement of waste residue when the cleaning brush cleans the filter cylinder. During cleaning, as the driving structure drives the cleaning brush to rotate, the waste residue generated during cleaning will fly out at a certain initial velocity. Due to the cover, the waste residue can be prevented from flying out of the cover. The waste residue inside the cover will be discharged regularly through the slag outlet at the bottom, preventing the waste residue from flying into the already cleaned filter cylinder area and preventing secondary clogging of the filter cylinder mesh, thereby ensuring the efficient cleaning effect of the cleaning brush on the filter cylinder.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0031] like Figure 1 and Figure 2 As shown, a slag discharge mechanism for a filter includes a filter, which includes: a tank 1 with a slag discharge port 8; a filter cylinder 4 disposed in the tank 1, the bottom of the filter cylinder 4 forming an opening communicating with the slag discharge port 8; a cleaning component for cleaning the mesh of the filter cylinder 4, the cleaning component including a cleaning brush 12 and a driving structure for driving the cleaning brush 12 to move relative to the filter cylinder 4; and a cover 14 for enclosing the cleaning brush 12, the cover 14 extending along the length of the cleaning brush 12 and forming a slag outlet communicating with the slag discharge port 8 at the bottom, one end of the cover 14 being open and the opening fitting against the filter cylinder 4 to form a semi-enclosed cleaning area, the cover 14 being able to move synchronously with the cleaning brush 12 so that the waste only moves inside the cover 14, thereby preventing the waste from flying into the outside of the cleaning area;

[0032] The above technical solution can prevent the irregular movement of waste residue when the cleaning brush 12 cleans the filter cylinder 4. In use, the drive structure is activated to make it move the cleaning brush 12 along the inner surface of the filter cylinder 4, thereby cleaning and unclogging the mesh of the filter cylinder 4. As the cleaning brush 12 rotates, the waste residue generated during cleaning will fly out at a certain initial speed. Since the cover 14 is provided, it can prevent the waste residue from flying out of the cover 14, and prevent the waste residue from flying into the area of ​​the already cleaned filter cylinder 4. The waste residue inside the cover 14 will be discharged regularly through the slag outlet at the bottom, preventing secondary clogging of the mesh of the filter cylinder 4, thereby ensuring the efficient cleaning effect of the cleaning brush 12 on the filter cylinder 4.

[0033] like Figure 1As shown, in this embodiment, the filter further includes: a tank cover 2 with an opening at the upper end of the tank body 1, the tank cover 2 having a feed inlet 3, and a discharge outlet 5 on one side of the tank body 1; a partition 6 in the tank body 1, the partition 6 being used to block the opening at the bottom of the filter screen cylinder 4, the partition 6 having a gap with the slag outlet at the bottom of the cover 14, the partition 6 having a through hole 7, and the through hole 7 being connected to the slag discharge outlet 8;

[0034] The above technical solution ensures that the oil enters the tank 1. When in use, the oil enters the upper tank 1 from the inlet 3, is filtered by the filter screen 4, and is discharged from the outlet 5. The residue in the oil is filtered by the filter screen 4 and remains on the inner wall of the filter screen 4. When the drive structure drives the cleaning brush 12 to clean the filter screen 4, the residue on the inner wall of the filter screen 4 falls off continuously. Then the through hole 7 is opened, and the oil containing the residue flows into the lower part of the tank 1 through the through hole 7 on the partition 6. After static separation, it is discharged from the slag discharge port 8.

[0035] like Figure 1 As shown, in this embodiment, the driving structure includes: a drive motor 9 located at the upper end of the can lid 2; a bracket 10 rotatably located at the lower end of the can lid 2, the bracket 10 being connected to the output shaft of the drive motor 9, the bracket 10 being connected to the cleaning brush 12, and the bracket 10 being fixedly connected to the cover 14.

[0036] The above technical solution can drive the cleaning brush 12 to revolve and clean the mesh on the surface of the filter cylinder 4. When in use, the drive motor 9 is started, and the output shaft of the drive motor 9 will drive the bracket 10 to rotate. In turn, the bracket 10 drives the cleaning brush 12 and the cover 14 to revolve synchronously, so that the cleaning brush 12 can clean the mesh on the surface of the filter cylinder 4.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the upper end of the cleaning brush 12 is provided with a connecting shaft 11, the connecting shaft 11 passes through the through groove 20 opened at the upper end of the cover 14, the connecting shaft 11 is rotatably connected to the bracket 10, and the connecting shaft 11 is connected with a gear 13, the gear 13 meshes with the annular rack 21 provided in the can lid 2;

[0038] The above technical solution enables the cleaning brush 12 to rotate on its own axis while revolving around the central axis, thereby improving the cleaning effect of the cleaning brush 12 on the filter cylinder 4. In use, when the bracket 10 drives the connecting shaft 11 to revolve around the central axis, the gear 13 at the upper end of the connecting shaft 11 will mesh with the ring rack 21 in the can lid 2, so that the gear 13 rotates on its own axis while revolving around the central axis, and the gear 13 drives the connecting shaft 11 and the cleaning brush 12 connected to it to rotate synchronously.

[0039] like Figure 2 and Figure 3As shown, in this embodiment, scraping components for scraping off waste residue are provided on both sides of the cover 14; specifically, the scraping components include scrapers 17 provided on the sides of the cover 14.

[0040] The above technical solution can help remove the waste residue attached to the mesh surface of the filter cylinder 4. By setting a scraper 17 on the side of the cover 14, when the drive motor 9 drives the cover 14 to revolve, the scraper 17 will also revolve synchronously with the cover 14, thereby scraping off the waste residue attached to the mesh surface of the filter cylinder 4.

[0041] like Figure 4 As shown, in this embodiment, a mounting base 15 is provided on the side of the cover 14. The mounting base 15 is rotatably connected to the end shafts 16 located at both ends of the scraper 17. A spring 18 is provided between the cover 14 and the scraper 17. The spring 18 is used to keep the scraper 17 in contact with the filter cylinder 4.

[0042] The above technical solution can keep the scraper 17 always in contact with the mesh of the filter cylinder 4. By setting the spring 18, elastic tension can be applied to the scraper 17 to ensure that the scraper 17 can be tightly in contact with the surface of the filter cylinder 4.

[0043] like Figure 4 As shown, in this embodiment, the surface of the scraper 17 is provided with a plurality of hollow grooves 19;

[0044] The above technical solution can reduce the amount of waste residue accumulated on the surface of the scraper 17. By opening the hollow groove 19, the waste residue can pass through the hollow groove 19 and pass through the scraper 17, preventing the accumulation of thick waste residue on the surface of the scraper 17 and ensuring the scraping effect of the scraper 17.

[0045] Working principle: During use, the oil enters the tank 1 through the inlet 3, is filtered by the filter screen 4, and is discharged through the outlet 5. The residue in the oil is filtered by the filter screen 4 and remains on the inner wall of the filter screen 4. When cleaning, the drive motor 9 is started so that its output shaft drives the bracket 10 to rotate. In turn, the bracket 10 drives the cleaning brush 12 and the cover 14 to revolve, so that the cleaning brush 12 cleans the mesh of the filter screen 4. When the bracket 10 drives the connecting shaft 11 to revolve, the gear 13 at the upper end of the connecting shaft 11 will mesh with the ring rack 21 in the tank cover 2, so that the gear 13 revolve and rotates at the same time. The gear 13 drives the connecting shaft 11 and the cleaning brush 12 connected to it to rotate synchronously, thereby improving the cleaning effect of the cleaning brush 12 on the filter screen 4.

[0046] Because of the cover 14, which is fixedly connected to the bracket 10, the cover 14 can always move synchronously with the cleaning brush 12, preventing waste residue from flying out of the cover 14 and avoiding waste residue from flying into the already cleaned filter cylinder 4 area, thus preventing secondary clogging of the filter cylinder 4 mesh. The waste residue inside the cover 14 will be discharged regularly through the slag outlet at the bottom, thereby ensuring the cleaning brush 12's efficient cleaning effect on the filter cylinder 4. In addition, by setting a scraper 17 on the side of the cover 14, the scraper 17 will also rotate synchronously with the cover 14, thereby scraping off the waste residue attached to the surface of the filter cylinder 4 mesh. The residue on the inner wall of the filter cylinder 4 continuously falls off, and then the through hole 7 is opened, and the oil containing residue flows into the lower part of the tank 1 through the through hole 7 on the partition 6. After settling and separation, it is discharged from the slag outlet 8.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
