Description

TECHNICAL FIELD

[0001] The application relates to the technical field of iron powder filtration, in particular to a disc filter for small-particle iron powder. BACKGROUND

[0002] At present, the disc filter is an indispensable device on the pipeline conveying medium, and is usually installed at the inlet end of a pressure reducing valve, a pressure relief valve, a constant level valve or other equipment, so as to eliminate impurities in the medium and protect the normal use of the valve and equipment. At present, the disc filter is often used in the process of screening and filtering iron powder. The disc filter comprises a filter tank for placing an iron powder and water mixture, a rotating motor fixedly installed on the filter tank, a rotating shaft connected with the output shaft of the rotating motor, a plurality of filter cartridges sleeved outside the rotating shaft, and filter screens arranged on the filter cartridges. When the iron powder is screened and filtered, the rotating shaft is driven to rotate by the rotating motor, so as to drive the filter cartridges to rotate. The filter cartridges adsorb the iron powder in the mixture of the iron powder and water in the tank, and collect the iron powder when the water flows out of the filter cartridges. According to the related technology in the above, when the material is fed into the disc filter, the concentration is relatively high, and part of the iron powder may be deposited at the bottom of the filter tank. The inventor believes that the iron powder deposited at the bottom of the filter tank cannot be adsorbed by the filter cartridges, thereby causing waste of the iron powder. CONTENT OF THE UTILITY MODEL

[0003] In order to improve the adsorption efficiency of the iron powder, the utility model provides a disc filter for small-particle iron powder.

[0004] The disc filter for small-particle iron powder provided by the utility model adopts the following technical scheme:

[0005] The disc filter for small-particle iron powder comprises a filter tank, a stirring assembly, a first auxiliary assembly and a second auxiliary assembly. The stirring assembly comprises a motor, a rotating shaft and a scraper. The motor is connected with the filter tank. The rotating shaft is rotationally connected with the filter tank. The driving shaft of the motor penetrates through the filter tank and is fixedly connected with the rotating shaft. The scraper is connected with the rotating shaft. The filter tank is connected with a supporting block. The supporting block is sleeved on the rotating shaft and is used for supporting the middle part of the rotating shaft. The first auxiliary assembly and the second auxiliary assembly are both rotationally connected with the supporting block. The rotating shaft is connected with a synchronous assembly. The first auxiliary assembly and the second auxiliary assembly are both synchronously moved with the rotating shaft through the synchronous assembly.

[0006] By adopting the above technical scheme, the motor of the stirring assembly drives the rotating shaft to rotate, and the scraper moves with the rotating shaft, which can uniformly stir the material in the filter tank, improve the adsorption efficiency of the iron powder, and reduce the waste of the iron powder; at the same time, the first auxiliary assembly and the second auxiliary assembly move synchronously with the rotating shaft through the synchronous assembly, which further enhances the stirring effect and ensures the uniformity and efficiency of the entire filtration process, further improving the adsorption efficiency of the iron powder. In addition, the design of the supporting block effectively supports the middle part of the rotating shaft, improves the overall stability and service life of the equipment.

[0007] Preferably, the scraper is connected with a movable plate, and the movable plate is in sliding abutment with the bottom of the filter tank.

[0008] By adopting the above technical scheme, the movable plate can slide along the bottom of the filter tank with the movement of the scraper, reducing the problem of filter cake accumulation at the bottom of the filter tank, improving the filtration efficiency and cleaning effect. At the same time, the design of the movable plate makes the scraper more flexible during cleaning, reduces equipment wear and tear, and prolongs the service life.

[0009] Preferably, the scraper is connected with a movable plate, and the movable plate is in sliding abutment with the bottom of the filter tank.

[0014] By adopting the above technical scheme, the stirring uniformity in the filter tank can be effectively enhanced, and the filtering efficiency of the iron powder can be improved. Specifically, the first auxiliary assembly and the second auxiliary assembly are respectively arranged at two sides of the rotating shaft, so that the materials in the entire filter tank can be fully stirred, and the possibility of uneven filtering caused by insufficient stirring in a local area is reduced. Meanwhile, the rotation connection of the auxiliary rod with the supporting block and the angular arrangement of the stirring blade enable the stirring blade to cover a wider area when rotating with the auxiliary rod, thereby further improving the stirring effect and improving the overall filtering performance.

Meanwhile, the end of each stirring blade away from the rotating shaft is in sliding abutment with the filter tank, which can further enhance the stirring effect and improve the filtering efficiency and quality.

[0017] Preferably, a cavity is formed in the supporting block, the rotating shaft passes through the cavity, the auxiliary rod extends into the cavity, and the synchronous assembly is arranged in the cavity.

This design not only improves the overall working efficiency of the equipment, but also ensures the uniform stirring of the materials in the filter tank, reducing the possibility of local accumulation or uneven mixing. At the same time, the stability and reliability of the gear transmission also enhance the operation stability of the entire system, prolonging the service life of the equipment.
