Description

Technical Field

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

[0002] A water storage tank is a tank used to store water. Its main structure is cylindrical. Water storage tanks are widely used in industry. Large water storage tanks are mostly used in industrial production, while small water storage tanks are mostly used in domestic water.

[0003] During the process of storing water in the water tank, the water pumped into the water tank needs to be preliminarily filtered in advance to intercept the dirt in the water by filtering to prevent the dirt from settling in the water tank and causing blockage of drainage structures such as the drainage pipes on the water tank.

[0004] The more common practice at present is to install a filter at the mouth of the storage tank. However, as the filtration retention volume increases, the filter is easily clogged by solid pollutants, which leads to a decrease in the filtration speed. Therefore, it needs to be disassembled and cleaned.

[0005] Therefore, in actual work, when the water quality is poor and the amount of dirt is high, the filter is frequently clogged. Frequent replacement and cleaning of the filter not only makes it extremely cumbersome to use, but also often causes the filter to be seriously clogged. During the process of pumping water into the water tank, the filter cannot be removed in time and can only be cleaned after the water is pumped. The serious blockage causes the speed of water passing through the filter to be very slow. Obviously, this method leads to great disadvantages in the process of pumping water into the water tank.

[0006] The essential reason for the above technical defects is that in actual use, the filter screen relies solely on a single structure, and the dirt attached to the filter screen cannot be detached, resulting in excessive blockage of the gap structure and inability to increase the water flow. Utility Model Content

[0007] Based on the above background, the purpose of the utility model is to provide a water tank self-cleaning filtering device.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] A water tank self-cleaning filter device, comprising a self-cleaning filter mechanism installed at the mouth of the water tank;

[0010] The self-cleaning filter mechanism comprises a mounting seat, on which a plurality of filter components are assembled and connected;

[0011] The self-cleaning filtering mechanism also includes an air blowing assembly for blowing the filtering assembly, the air blowing assembly includes a plurality of air blowing pipes, and the air outlet end of the air blowing pipe is equipped with an air nozzle facing the filtering assembly (the air nozzle adopts a conventional pump air nozzle tube disclosed in the prior art, which increases the air droop rate by reducing the size of the air outlet end).

[0012] The air inlet end of the air blowing pipe is connected to an air inlet main pipe;

[0013] The air blowing assembly also includes an adjusting structure for adjusting the height of the air blowing assembly. When the air is blown to remove dirt attached to the filter assembly, the height of the air blowing assembly is lowered through the adjusting structure until the air nozzle extends into the filter assembly.

[0014] Preferably, an annular flange mounting plate is welded to the top edge of the mounting seat, and the annular flange mounting plate is fastened to the side wall of the water tank mouth.

[0015] Preferably, the air blowing pipe comprises an oblique body portion tilted downward, the oblique body portion is integrally formed with a vertical body portion vertically disposed downward, and the air nozzle is welded at the air outlet end of the vertical body portion;

[0016] The upper end of the oblique body is connected to a vertically arranged air intake manifold.

[0017] Preferably, the air intake manifold is connected to a bent connecting pipe, and the air intake end of the bent connecting pipe is connected to a pipeline joint.

[0018] Preferably, the filter assembly comprises a filter cartridge mounted on a mounting seat, and a plurality of strip-shaped filter holes are formed on the side wall of the filter cartridge;

[0019] The filter assembly also includes a filter bag fixed in the filter cartridge;

[0020] The air nozzle faces the filter bag.

[0021] Preferably, the filter assembly is detachably mounted on the mounting seat;

[0022] An annular flange mounting seat is welded on the top of the filter cartridge, and the annular flange mounting seat is fastened on the mounting seat by a plurality of fastening screws.

[0023] Preferably, the regulating structure comprises a fixing seat fixedly connected to the intake manifold;

[0025] Preferably, the adjusting rod comprises a fixing rod slidably connected to the fixing seat, and a supporting nut supported at the bottom position of the mounting seat is threadedly connected to the fixing rod.

[0026] Preferably, the transverse cross-section of the mounting seat is circular.

[0027] The utility model has the following beneficial effects:

[0028] 1. During the working process, when it is necessary to blow air into the filter assembly to remove the dirt that is blocking the filter assembly, at this time, turn on the air pump in the above manner, and the air pump pumps out an airflow of a certain pressure from the air nozzle position, and as the air nozzle pumps an airflow of a certain pressure into the filter assembly, under the action of the airflow, the blockage on the filter structure in the filter assembly is removed, thereby improving the water filtration efficiency while increasing the water passing rate.

[0029] 2. The filter assembly includes a filter cartridge installed on a mounting seat, and a plurality of strip filter holes are opened on the side wall of the filter cartridge; the filter assembly also includes a filter bag fixed in the filter cartridge. During the process of air blowing to remove the blockage, since the filter bag is made of soft material, the filter bag swings violently during the air blowing process, thereby quickly shaking off the dirt blocking the filter holes on the filter bag. The above method not only greatly improves the efficiency of removing the material blocking the filter holes, but also the air blowing method can stop pumping water if the water flow speed is slow during the water pumping process, and immediately blow the blockage away. And the dirt shaken off falls into the filter bag and will not pollute the water quality again. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] like Figure 1-5 As shown, a self-cleaning filter device for a water tank includes a self-cleaning filter mechanism installed at the mouth of the water tank. The self-cleaning filter mechanism enables the filtered dirt to be shaken and dropped from the filter holes on the filter structure, increasing the number of filter holes, thereby ensuring the water passing rate during the filtering process, and avoiding the defect of too slow water passing speed due to excessive blockage of the filter hole structure.

[0042] Specifically, the self-cleaning filter mechanism comprises a mounting seat 1 , on which a plurality of filter components are assembled and connected.

[0043] At the same time, the self-cleaning filtering mechanism also includes an air blowing assembly for blowing the filtering assembly, the air blowing assembly includes a plurality of air blowing pipes 41, the air outlet end of the air blowing pipe 41 is equipped with an air nozzle 411 facing the filtering assembly; the air inlet end of the air blowing pipe 41 is connected to an air inlet main pipe.

[0044] Specifically, the air blowing assembly also includes an adjusting structure for adjusting the height of the air blowing assembly. When the air is blown to remove dirt attached to the filter assembly, the height of the air blowing assembly is lowered through the adjusting structure until the air nozzle 411 extends into the filter assembly.

[0045] Specifically, the air blowing pipe 41 includes an oblique body portion tilted downward, the oblique body portion is integrally formed with a vertical body portion vertically downward, and the air nozzle 411 is welded to the air outlet end of the vertical body portion; at the same time, the upper end of the oblique body portion is connected to the vertically arranged air intake main pipe.

[0046] The intake manifold is connected with a curved connecting pipe 42, and the intake end of the curved connecting pipe 42 is connected with a pipe joint. According to the existing conventional method, the curved connecting pipe 42 is connected to an exhaust pipe such as an air pump (not shown) through a pipe joint 421.

[0047] During the operation, when it is necessary to blow air into the filter assembly to remove the dirt that is blocking the filter assembly, at this time, turn on the air pump in the above manner, and the air pump pumps out an airflow of a certain pressure from the air nozzle 411. As the air nozzle 411 pumps an airflow of a certain pressure into the filter assembly, the blockage on the filter structure in the filter assembly is removed under the action of the airflow, thereby improving the water filtration efficiency while increasing the water passage rate.

[0048] Example 2

[0049] like Figure 1-5 As shown, this embodiment is based on the structure of embodiment 1, and in order to increase the effect of air blowing to remove blockages from the filtering structure during actual working, the above-mentioned adjustment structure includes a fixed seat 44 fixedly connected to the air intake manifold; a plurality of adjustment rods are fixedly connected to the mounting seat 1, and the fixed seat 44 is adjusted in height by adjusting the rods.

[0050] Specifically, the adjusting rod comprises a fixing rod 43 slidably connected to the fixing seat 44 , and a supporting nut 431 supported at the bottom position of the mounting seat 1 is threadedly connected to the fixing rod 43 .

[0051] During operation, the support nut 431 is screwed in the direction at this time, and the fixed seat 44 carries the air blowing assembly down to the vertically arranged air nozzle 411 to penetrate into the filter assembly to achieve an increased air blowing effect. After adjusting the height, the curved connecting pipe 42 is then connected to the exhaust pipe of the air pump in the above manner. (In the actual operation process, according to the existing conventional method, the exhaust pipe of the air pump can be connected to the upper hose to facilitate height adjustment).

[0052] Example 3

[0053] like Figure 1-5 As shown, this embodiment discloses the structure of the filter assembly based on the structure of Embodiment 2, which is as follows:

[0054] The filter assembly includes a filter cartridge 2 installed on a mounting seat 1 (the installation method is: the filter cartridge 2 is sleeved on the mounting hole opened on the mounting seat 1; an annular flange mounting seat 21 is welded on the top of the filter cartridge 2, and the annular flange mounting seat 21 is fastened to the mounting seat 1 by a plurality of fastening screws, which realizes subsequent convenient disassembly and is easy to clean), and a plurality of strip filter holes 22 are opened on the side wall of the filter cartridge 2; the filter assembly also includes a filter bag 3 fixed in the filter cartridge 2; wherein the filter bag 3 is a conventional filter bag 3 for filtering water disclosed in the prior art, which is formed of a flexible material such as nylon material.

[0055] According to the existing method, the mouth of the filter bag 3 is fixed on the inner wall of the filter cartridge 2. The advantages of using the filter bag 3 structure are: forming a double-layer filtration with the strip filter holes 22 on the filter cartridge 2, and secondly, because the filter bag 3 is made of soft material, the filter bag 3 swings violently during the air blowing process, thereby quickly shaking off the dirt blocking the filter holes on the filter bag 3.

[0056] The above method not only greatly improves the efficiency of removing the material that blocks the filter pores, but also the air blowing method can stop pumping water if the water flow rate is slow during the water pumping process, and immediately blow the air to remove the blockage. The dirt shaken off falls into the filter bag 3 and will not pollute the water quality again.

[0057] Example 4

Specifically, an annular flange mounting plate 11 is welded to the top edge of the mounting seat 1, and the annular flange mounting plate 11 is fastened to the side wall of the mouth of the water tank. The specific method is that the bolts penetrate through the mounting through holes on the annular flange mounting plate 11 and are fastened to the position of the mouth of the water tank.

[0059] During the water pumping process, water is trapped on the mounting base 1 and is quickly and synchronously filtered along the multiple filter components on the mounting base 1 .

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
