Description

Technical Field

[0001] The utility model relates to the field of filter element manufacturing and processing, in particular to a filter element with replaceable activated carbon. Background Art

[0002] The filter element separates solid particles in a liquid or gas, or enables different substance components to fully contact, shortening the reaction time, protecting the normal operation of equipment or the cleanliness of air. When a fluid enters a filter element with a filter screen of a certain specification, its impurities are blocked, and the clean fluid flows out through the filter element. The liquid filter element makes a liquid (including oil, water, etc.) be purified to the state required for production and life, that is, makes the liquid reach a certain cleanliness level.

[0003] The activated carbon filter element increases the adsorption effect of the filter element, adsorbs the impurities passing through the filter material, and then discharges the clean fluid, improving the filtering effect.

[0004] After the activated carbon filter element is used for a long time, a large amount of impurities will accumulate in the activated carbon, and the filtering effect of the filter element will be reduced. The entire filter element needs to be replaced, wasting materials and increasing costs. Content of the Utility Model

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A filter element with replaceable activated carbon includes filter paper, activated carbon, metal meshes, end cap one and end cap two. The metal meshes are cylindrical, there are two of them, which are interspersed with each other. There is a gap between the two metal meshes. The activated carbon is filled between the two metal meshes. The filter paper is sleeved on the outermost side of the metal meshes. Fixing rings are respectively adhered to the upper and lower parts of the whole body of the filter paper. The end cap one and the end cap two are respectively located at the two ends of the filter paper. The end cap one is fixedly connected to the end of the fixing ring. The port of the metal mesh is adhered to the end cap one. A threaded cylinder is fixedly connected to the middle of the end cap two. A vertical retaining edge is fixedly connected to the edge of the end cap two. A connecting ring is fixedly connected to the inner wall of the innermost wire mesh. Threads are provided on the whole body of the connecting ring. The threaded cylinder is located inside the wire ring and is threadedly connected to the connecting ring. The retaining edge is located outside the filter paper and contacts the fixing ring.

[0008] By adopting the above technical solution, by unscrewing the end cap at one end of the filter element, the activated carbon inside it can be replaced, extending the service life of the filter element, saving resources and reducing costs.

[0009] Preferably, friction lines are provided on the outer side of the retaining edge of the end cap two.

[0010] Adopting the above technical solution facilitates the screwing of the second end cap.

[0011] Preferably, a rubber ring is fixedly connected to the inner wall of the retaining edge.
