Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter with good sealing tightness. Background Art

[0002] Precision filter (also known as security filter), the shell is generally made of stainless steel, and the internal tubular filter element is made of PP melt-blown, wire-sintered, folded, titanium filter element, activated carbon filter element, etc. as the filter element. Different filter elements are selected according to different filter media and design processes to meet the requirements of effluent water quality. It is used for solid-liquid separation of various suspensions, high environmental requirements, and high filtration accuracy of liquid medicine filtration. It has a wide range of applications and is suitable for industrial fields such as medicine, food, chemical industry, environmental protection, and water treatment.

[0003] The current sewage station uses a security filter, which is equipped with a skeleton filter rod with a precision of 5 microns. The original installation method is to install a plastic joint at the bottom of the filter rod, one end is inserted into the filter rod and the other end is inserted into the bottom plate of the filter.

[0004] However, the prior art still has some shortcomings. In the prior art, because the filter rod is too long and the internal space of the filter is limited, the filter rod is difficult to install and the plate hole is often not found, which reduces the installation efficiency and also reduces the sealing performance.

[0005] Therefore, we propose a filter with good sealing tightness to solve this problem. Utility Model Content

[0006] The purpose of the utility model is to solve the problems raised in the above background technology and to provide a filter with good sealing tightness.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A filter with good sealing tightness comprises a support column; a cylinder body is fixedly connected to the upper surface of the support column; a water outlet is fixedly connected to one side of the outer circumferential surface of the cylinder body; a water inlet is fixedly connected to the other side of the outer circumferential surface of the cylinder body; a sealing cover is fixedly connected to the upper surface of the cylinder body; a sleeve is fixedly connected to the inner bottom surface of the cylinder body; and a filter rod is fixedly connected to the upper surface of the sleeve.

[0009] Preferably, the sleeve is a conical sleeve; a rubber block is fixedly connected to the lower side of the outer circumferential surface of the sleeve.

[0010] Preferably, the outer circumferential surface of the sleeve is provided with a through hole; the through hole is located above the rubber block.

[0011] Preferably, a mounting groove is provided on the lower surface of the filter rod; the mounting groove is a conical groove.

[0012] Preferably, the filter rod is fixed to the upper surface of the sleeve through a mounting groove.

[0013] Preferably, the inner diameter of the upper end of the sleeve is much smaller than the inner diameter of the mounting groove.

[0014] In the utility model, the filter with good sealing tightness is provided by the arrangement of the sleeve, the rubber block, the filter rod and the installation groove. When installing the filter rod, the installation groove is aligned with the sleeve and the filter rod is pressed downward. Because the sleeve is conical and the inner diameter of the upper end is much smaller than the inner diameter of the installation groove, the sleeve can be easily inserted into the installation groove. As the filter rod is pressed downward, the inner wall of the installation groove and the outer wall of the sleeve are gradually pressed tightly, thereby achieving the sealing tightness of the filter rod. The sealing can be further improved by the rubber block.

[0015] In the utility model, the filter with good sealing tightness can avoid the problem of reducing the filtering area due to the addition of sleeves and prevent the reduction of filtering efficiency by setting the through holes;

[0016] The utility model has reasonable structural design, simple operation and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
