Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a high-conductivity needle filter. Background Art

[0002] The syringe filter is a commonly used micro-filtration device used to filter and separate fine particles from liquids or gases. It consists of a slender syringe-shaped filter element, usually made of stainless steel or other corrosion-resistant materials. The working principle of the syringe filter is to trap particles in the filter element through the microporous grid or multi-layer filter screen inside the filter element, thereby purifying the liquid or gas. According to needs, the filter element can choose different pore sizes to meet the requirements of filtering particles of different particle sizes.

[0003] The upper shell and the lower shell of the current syringe filter are generally connected by buckles or screws when fixed. Gaps are easily generated during buckle connection, and screw connection requires the use of specific tools, which affects work efficiency and filtering effect.

[0004] Therefore, there is an urgent need to provide a high-conductivity needle filter to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the upper shell and the lower shell of the current syringe filter are generally connected by buckles or screws when fixed, and gaps are easily generated during the buckle connection, and the screw connection requires the use of specific tools, which affects the work efficiency and the filtering effect.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a high-conductivity needle filter, comprising an upper shell, the top of which is fixedly connected to a feed pipe, a lower shell is installed at the bottom of the upper shell, and the bottom of the lower shell is fixedly connected to a discharge pipe;

[0007] A connecting assembly is installed between the upper shell and the lower shell, a filter membrane is fixedly connected to the center of the upper shell, and a sealing strip is fixedly connected to the bottom of the upper shell.

[0008] The utility model is further configured as follows: through holes are provided on the upper shell and the lower shell, and the feed pipe and the discharge pipe both pass through the centers of the corresponding through holes.

[0009] Through the above technical solution, the material can enter the center of the filter through the feed pipe for filtration, and can be discharged through the discharge pipe after filtration, thereby completing the filtration operation and realizing the circulation of the material.

[0010] The utility model is further configured as follows: the connecting assembly includes positioning columns fixedly connected to both sides of the bottom of the upper shell, first mounting blocks are fixedly connected to both sides of the outer wall of the upper shell, second mounting blocks are fixedly connected to both sides of the outer wall of the lower shell, the bottoms of the two first mounting blocks are fixedly connected to fixing columns, and the outer walls of the two fixing columns are threadedly connected to locking plates.

[0011] Through the above technical solution, the locking plate is rotated so that it can be threaded on the outer wall of the fixing column until the locking plate corresponds to the limiting hole of the second mounting block. Then the first mounting block and the second mounting block can be directly separated to complete the disassembly and clean the filter membrane.

[0012] The utility model is further configured as follows: positioning holes are opened on both sides of the top of the lower shell, and the two positioning posts pass through the centers of the positioning holes.

[0013] Through the above technical solution, rapid positioning during installation can be achieved through two positioning columns. The positioning columns enter the center of the positioning holes to align the first mounting block with the second mounting block, which facilitates subsequent fixing and locking operations and improves the portability of the operation.

[0014] The utility model is further configured as follows: two of the second mounting blocks are each provided with a limiting hole, and two of the fixing columns both pass through the center of the limiting hole.

[0015] Through the above technical solution, after the fixing column enters the center of the limiting hole, it can be locked by operating the locking plate, which improves the portability of operation, ensures the connection stability between the second mounting block and the first mounting block, and improves the connection strength.

[0016] The utility model is further configured as follows: the two locking plates are respectively tightly fitted with the two second mounting blocks.

[0017] Through the above technical solution, a locking connection can be achieved between the locking plate and the second mounting block. The locking plate provides extrusion force to the second mounting block, so that it fits tightly with the first mounting block. Combined with the sealing strip, it can have strong sealing properties, ensuring that the filter will not leak, thereby increasing the safety of the equipment.

[0018] The utility model is further configured as follows: the filter membrane is made of polyvinylidene fluoride as a raw material.

[0019] Through the above technical scheme, the filter membrane has high mechanical strength, high tensile strength, good heat resistance and chemical stability, low protein adsorption rate, and a long service life, which ensures the use effect, improves the material filtration effect, and improves the processing quality.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1. The utility model provides a connection assembly so that the upper shell and the lower shell can be quickly connected, and have high stability during connection. The positioning column is used for rapid positioning, which is convenient for subsequent locking operations. The locking plate is tightly fitted with the second mounting block during locking, and has a certain sealing performance;

[0022] 2. The utility model provides a sealing strip so that the upper shell and the lower shell can have a higher sealing performance, which can prevent liquid or gas leakage, enhance the sealing performance and stability of the filter, and thus ensure the filtering effect and the normal operation of the equipment.
