Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more particularly to a water treatment filter with the effect of alleviating water flow impact. Background Art

[0002] Precision filter is a kind of deep processing and separation equipment for liquid or gas. It is a device specially used to filter solid suspended particles in samples. It can filter solid particles with a particle size of 1-10um in the sample. The finished product can be supplied to subsequent process equipment with higher processing requirements: it is suitable for thermal power plants including boiler feed water, casting, papermaking, metallurgy, food, medicine and other industries.

[0003] Currently, the precision filter elements on the market are mainly fixed with pressure plates and bolts. In actual use, this type of precision filter is prone to shaking due to water flow impact and other reasons, thereby transmitting the force to the nut, making the filter element unstable or even falling off. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A water treatment filter with the effect of slowing down water flow impact comprises a filter cylinder, a filter element installed in the filter cylinder, and a filter cover. A pressure plate is provided in the filter cylinder and on the top of the filter element. A buffer mounting mechanism is provided on the inner wall of the filter cylinder, and the buffer mounting mechanism is used to buffer and limit the pressure plate.

[0007] The buffer mounting mechanism includes a fixed block fixedly mounted on the filter cylinder, a bolt fixedly connected to the fixed block, a mounting hole opened on the pressure plate, the pressure plate is sleeved on the bolt through the mounting hole, a nut is threadedly connected above the pressure plate and located on the bolt, a buffer spring is sleeved on the bolt, and the buffer spring is located between the pressure plate and the nut.

[0008] As a further description of the above technical solution: the buffer installation mechanism is at least two groups and is evenly distributed on the inner wall of the filter cylinder.

[0009] As a further description of the above technical solution: a plurality of through holes are opened on the pressing plate, and the thickness of the pressing plate is 2-5 mm.

[0010] As a further description of the above technical solution: the pressure plate is made of stainless steel or aluminum alloy.

[0011] As a further description of the above technical solution: the buffer spring is made of high-elastic alloy steel, and the elastic coefficient of the buffer spring is 50-100N / mm.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] In order to meet the actual use needs and versatility, this solution uses a new installation method of putting a buffer spring between the bolt and the nut to buffer the force generated by the impact of the water flow. The contact surface between the buffer spring and the nut is small, and it is not easy to transmit the force to the nut and cause it to fall off. It is suitable for all flat-bottom precision filters on the market. BRIEF DESCRIPTION OF THE DRAWINGS
