Description

Technical Field

[0001] The utility model belongs to the technical field of biological filter tanks, and particularly relates to a self-cleaning mechanism and a filtering device for a biological filter tank. Background Art

[0002] Biofilter is a biological treatment structure made of crushed stone or plastic fillers. The sewage comes into contact with the gaps between the membranes of microorganisms growing on the surface of the fillers, thus purifying the sewage.

[0003] However, there are some problems with the prior art: the biological filter mainly utilizes the microbial community growing on the surface of the filter material to adsorb and degrade pollutants such as organic matter in the sewage, and the biological filter allows water to be filtered through the filter element to remove impurities and odors inside it, but the filter element in the biological filter needs to be cleaned after long-term use. If the filter element is not cleaned properly, it will also lead to unqualified water treatment in the biological filter, and the filter element does not have a self-cleaning function, which will also result in the filter element needing to be replaced after long-term use, thereby increasing the cost of replacing the filter element. Therefore, we propose a self-cleaning mechanism and a biological filter filtering device. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a self-cleaning mechanism and a biological filter tank filtering device, which have the advantage of self-cleaning of the biological pool filter element, and solve the problem of allowing water to pass through the filter element in the biological filter tank for filtering, thereby removing impurities and odors inside the filter element. However, the filter element in the biological filter tank needs to be cleaned after long-term use. If the filter element is not cleaned properly, it will also lead to unqualified water treatment in the biological filter tank. Moreover, the filter element does not have a self-cleaning function, which will also result in the filter element needing to be replaced after long-term use, thereby increasing the cost of replacing the filter element.

[0005] The utility model is implemented in this way: a self-cleaning mechanism comprises:

[0006] A frame, wherein the interior of the frame is connected with a plurality of connecting pipes, the surface of the connecting pipes is connected with a plurality of air outlet heads, the front and rear sides of the bottom of each group of air outlet heads are fixedly installed with a first rotating block, the surface of the connecting pipes is fixedly installed with a plurality of second rotating blocks, the first rotating block on the rear side is rotatably installed by an axle pin and the second rotating block, a pull rod is fixedly installed on the right side of the first rotating block on the front side, the front end of the pull rod passes through the front side of the second rotating block and is rotatably installed with the second rotating block, a pulling block is fixedly installed on the top of the pull rod, a plurality of pull ropes are arranged inside the frame, the left side of the pull rope passes through the left side of the frame, and the right side of the pull rope passes through the right side of the frame.

[0007] Stoppers are arranged on both sides of each group of the pulling blocks, the inner sides of the stoppers are in contact with the two sides of the pulling blocks, and one side of the pull rope passes through the stoppers and is slidably mounted with the stoppers.

[0008] Clamps are fixedly installed on both sides of the frame, and a clamping block is rotatably installed inside the clamping plate through an axle pin. The pull rope is located inside the clamping plate, and the bottom of the clamping block contacts the top of the pull rope.

DETAILED DESCRIPTION

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, a self-cleaning mechanism provided by an embodiment of the utility model includes:

[0026] A frame 1, the interior of the frame 1 is connected with a plurality of connecting pipes 2, and the surface of the connecting pipes 2 is connected with a plurality of gas outlets 3;

[0027] The bottom of the gas outlet head 3 is a retractable bellows, and the gas outlet head 3 is a flat-mouthed gas outlet head 3, so that the gas outlet pressure of the gas outlet head 3 can be increased, so that the biological filtration pool that needs to be cleaned can be cleaned;

[0028] The front and rear sides of the bottom of each group of air outlet heads 3 are fixedly installed with a first rotating block 4, and a plurality of second rotating blocks 5 are fixedly installed on the surface of the connecting pipe 2. The rear first rotating block 4 is rotatably installed through an axle pin and the second rotating block 5, and a pull rod 6 is fixedly installed on the right side of the front first rotating block 4. The front end of the pull rod 6 passes through the front side of the second rotating block 5 and is rotatably installed with the second rotating block 5. A pulling block 7 is fixedly installed on the top of the pull rod 6, and a plurality of pull ropes 8 are arranged inside the frame 1. The left side of the pull rope 8 passes through the left side of the frame 1, and the right side of the pull rope 8 passes through the right side of the frame 1.

[0029] Connect the pipe at one end of the frame 1 to the fan, and then start the fan. The fan extracts the outside air and transports it to the inside of the frame 1. The frame 1 then transports the air to the inside of the connecting pipe 2. The air inside the connecting pipe 2 is then transported to the air outlet 3. Finally, the air outlet 3 can clean the biological filter pool that needs to be cleaned.

[0030] When the angle of the air outlet head 3 needs to be adjusted, for example, when air needs to be blown to the left, the pull rope 8 can be pulled to the left, and the pull rope 8 moves to drive the pulling block 7 and the pull rod 6 to rotate, and the rotation of the pull rod 6 drives the air outlet head 3 to rotate forward, and the rotation of the air outlet head 3 can clean the biological filter pools at different positions;

[0031] Finally, when the angle of the blowing head needs to be adjusted to the right, the pull rope 8 can be pulled to the right. The movement of the pull rope 8 drives the pulling block 7 and the pull rod 6 to rotate. The rotation of the pull rod 6 drives the air outlet head 3 to rotate to the right. The rotation of the air outlet head 3 can clean the biological filtration pool at different positions.

[0032] Stoppers 9 are provided on both sides of each group of pulling blocks 7 , the inner sides of the stoppers 9 are in contact with both sides of the pulling blocks 7 , and one side of the pull rope 8 passes through the stoppers 9 and is slidably mounted with the stoppers 9 .

[0033] By setting the stopper 9, the stopper 9 can be driven to move when the pull rope 8 is pulled, and the movement of the stopper 9 drives the pulling block 7 and the pull rod 6 to rotate, and the rotation of the pull rod 6 allows the air outlet head 3 to rotate, thereby achieving the advantage of adjusting the angle of the air outlet head 3, so that the biological pools at different positions can be cleaned.

[0034] Clamps 10 are fixedly installed on both sides of the frame 1 , and clamp blocks 11 are rotatably installed inside the clamps 10 through axle pins. The pull rope 8 is located inside the clamps 10 , and the bottom of the clamp block 11 contacts the top of the pull rope 8 .

[0035] By setting the splint 10 and the clamp block 11, the pull rope 8 can drive the air outlet head 3 to move to a suitable angle. At this time, the splint 10 can be rotated toward the bottom so that the bottom of the clamp block 11 contacts the top of the pull rope 8, thereby limiting the pull rope 8 and preventing the pull rope 8 from being unable to apply tension to the pull rope 8 when the air outlet head 3 is adjusted to a suitable angle, thereby causing the air outlet head 3 to be reset.

[0036] A clamping block 12 is rotatably mounted on the back of the clamping plate 10 via an axle pin, a buckle 13 is fixedly mounted on the back of the clamping block 11 , and a round block 20 is fixedly mounted on the front side of the buckle 13 .

[0037] By setting the clamping block 12 and the buckle 13, after the clamping block 11 limits the pull rope 8, the clamping block 12 can be rotated to engage with the buckle 13, thereby limiting the clamping block 11 and preventing the clamping block 11 from limiting the pull rope 8 poorly.

[0038] A plurality of groups of limiting sleeves 14 are fixedly mounted on the top of the connecting pipe 2 , and the bottom of the air outlet head 3 is located inside the limiting sleeves 14 .

[0039] By setting the limiting sleeve 14, the air outlet head 3 can be limited to prevent the air outlet head 3 from being unable to return to its original position after the angle is adjusted, thereby causing poor practicality of the air outlet head 3.

[0040] A biological filter tank filtering device also includes a filter plate 15, wherein a filter layer 16 and an activated carbon particle layer 17 are sequentially arranged inside the filter plate 15, and mounting plates 18 are fixedly installed on both sides of the filter plate. The filter plate 15 is located on the top of the frame 1.

[0041] The filter layer 16 is made of gravel and crushed stone, which can filter impurities in the biological pool. The activated carbon granule layer 17 is made of activated carbon, which can effectively purify the odor of the biological pool water.

[0042] By setting the filter plate 15, the filter layer 16, the activated carbon particle layer 17 and the mounting plate 18, the mounting plate 18 is installed inside the biological pool, and then the water in the biological pool first passes through the filter layer 16 to filter out impurities inside it, and then passes through the activated carbon particle layer 17 to purify the odor inside the purifier, thereby achieving the advantages of filtering the biological pool.

[0043] Four groups of support plates 19 are fixedly mounted on the inner side of the mounting plate 18 . The top of the support plate 19 contacts the bottom of the filter plate 15 , and the bottom of the support plate 19 is fixedly mounted on the top of the frame 1 .

[0044] By providing the support plate 19, the filter plate 15 can be supported to prevent the filter plate 15 from being too heavy and coming into contact with the frame 1, thereby reducing the cleaning range of the air outlet head 3 inside the frame 1, resulting in a poor cleaning effect.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
