Description

Technical Field

[0001] The utility model relates to the technical field of double-valve filters, in particular to a gravity-type air-scrubbing double-valve filter. Background Art

[0002] Gravity filter is a device that relies on the static pressure generated by the weight of the liquid to filter. Generally, a porous plate is placed at an appropriate height from the bottom of the cylinder and covered with filter media to form a gravity filter. There are many types of gravity filters, and gravity air scrubbing double valve filter is one of them.

[0003] A gravity-type air scrubbing double-valve filter disclosed in publication number CN220703313U is equipped with an outer rubber ring, an anti-sway lower ring block and a sealing lower soft pad compared to the existing double-valve filter. The combined design of the outer rubber ring, the anti-sway lower ring block and the sealing lower soft pad can effectively reduce the gap of the limit lower ring block when it is fixed, so that the sealing performance of the filter cover and the double-valve filter body is higher, which solves the problem that the service life of the existing gravity-type air scrubbing double-valve filter is often greatly reduced due to insufficient sealing during use;

[0004] However, the above scheme still has the following problems during use: when in use, the upper cover and the filter body are connected and reinforced by screwing bolts one by one, and sealed with a rubber ring. This method is time-consuming, labor-intensive and cumbersome to operate, which affects the convenience of using the gravity-type air scrubbing double-valve filter.

[0005] So we proposed a gravity-type air-scrubbing double-valve filter to solve the above-mentioned problems. Utility Model Content

[0008] It also includes: a sealing ring is installed at the bottom of the sealing cover, and the sealing ring is plug-connected with the sealing groove, and the sealing groove is opened at the top of the filter body;

[0009] The bottom of the cover is connected with a locking rod at an equal angle, and the locking rod is connected and fixed with the through hole, and the through hole is correspondingly opened at the top of the filter body;

[0010] A sealing bag is installed inside the sealing ring, and the sealing bag fills the gap between the sealing ring and the sealing groove;

[0011] The inner top bearing of the filter body is connected with a driving fan, and the bottom of the driving fan is connected with a cleaning rod, and the cleaning rod is in close contact with the filter screen, and the filter screen is installed above the inner part of the filter body.

[0012] Preferably, a knob is connected through the middle of the top surface of the cover, and a large gear is fixed to the bottom of the knob, and a small gear is meshed and connected to the outside of the large gear at an equal angle, and both the large gear and the small gear are bearing-connected to the inner middle of the cover.

[0013] Preferably, a locking rod is integrally mounted on the bottom of the pinion gear, and the locking rod is configured as a "T"-shaped structure, and the bottom of the locking rod is connected through the through hole, and the through hole is configured as a rectangular structure.

[0014] Preferably, an arc-shaped guide groove is opened at an equal angle at the bottom of the large gear, and a movable rod is slidably connected in the guide groove, and the bottom of the movable rod is slidably connected to the limit groove, and the limit groove is opened at an equal angle at the lower inner side of the cover, and the limit groove is set as a rectangular structure.

[0015] Preferably, the movable rod is arranged as an "L"-shaped structure, and the movable rod forms an opening and closing sliding structure through a guide groove and a limit groove, and the movable rod is squeezed and abutted against the air bag, and the air bag is installed at an equal angle inside the cover, and the outlet of the air bag is connected to the sealing bag.

[0016] Preferably, the cleaning rod and the filter are both arranged in an inverted "V"-shaped structure, and the driving fan drives the cleaning rod and the filter to form a rotating cleaning mechanism, and a collecting outlet is arranged at the bottom of the filter.

[0018] Compared with the prior art, the utility model gravity air scrubbing double valve filter has the following beneficial effects: when in use, the cover and the filter can be double sealed to avoid the problem of greatly reducing the service life of the equipment due to insufficient sealing, and the cover and the filter can be conveniently connected through the locking rod and the through hole, and the filtered impurities can be cleaned in time during air scrubbing. The specific contents are as follows:

[0019] 1. By setting the locking rod and the through hole, the cover and the filter can be conveniently and firmly connected and fixed, thereby improving the efficiency of the gravity air scrubbing double valve filter when in use;

[0020] Furthermore, after the large gear drives the small gear to rotate, the small gear drives the locking rod to rotate.

After the large gear drives the guide groove to rotate, the guide groove drives the movable rod to move, and the movable rod slides open and close under the limiting action of the limiting groove. After the movable rod slides, it squeezes the air storage bag, and the air storage bag will transport the gas to the sealing bag, and the sealing bag will expand, so as to perform a secondary sealing treatment between the sealing cover and the filter body, thereby improving the sealing performance of the filter and avoiding affecting the service life of the filter body due to poor sealing.

[0022] 3. By setting the driving fan and the cleaning rod, the cleaning effect of impurities can be improved during air scrubbing to avoid the accumulation of impurities and affect the subsequent work. When the driving fan rotates, it will drive the cleaning rod at the bottom to rotate, and when the cleaning rod rotates, it will clean the impurities intercepted on the filter screen;

[0023] Furthermore, when the cleaning rod rotates, the knocking rod will intermittently overlap with the magnetic block, and then it will rotate under the action of magnetic adsorption, thereby reversing the torsion spring. When the knocking rod is misaligned with the magnetic block, the knocking rod will reset and rotate under the action of the torsion spring, thereby hitting the cleaning rod, causing the cleaning rod to vibrate, shake off the dust adhered to itself, and achieve a self-cleaning effect.
