Description

Technical Field

[0001] This utility model relates to a T-type filter for conveying liquid materials, and belongs to the technical field of T-type filter. Background Technology

[0002] T-type filters are widely used in various fields, such as fire-fighting pipelines in lithium battery production lines. A T-type filter is a small device that removes small amounts of solid particles from liquids, protecting the equipment's normal operation. When fluid enters the filter cartridge containing a filter screen of a specific size, impurities are blocked, while clean filtrate is discharged from the filter outlet. When cleaning is required, simply remove the detachable filter cartridge, clean it, and reinstall it. Therefore, its use and maintenance are extremely convenient.

[0003] Chinese utility model patent CN219355512U discloses a T-type filter. The position of the filter cartridge is adjusted by rotating the screw, so that the filter cartridge and the conical cylinder fit together. In addition, the conical cylinder is made of rubber, which improves the sealing performance between the filter cartridge and the conical cylinder and prevents water from flowing out between the filter cartridge and the conical cylinder. The sealing ring is set to keep the right side of the filter cartridge in a sealed environment to prevent water from reaching the right side of the filter cartridge, thereby preventing the bearing, the second nut and the screw from being corroded.

[0004] However, the above-mentioned patented solutions have the following inconveniences in actual use: First, filtration is only carried out on one side of the filter cartridge, while the rest is in contact with the inner wall of the tube, so the filtration area is small and it is easy to get clogged; Second, it is impossible to control the flow of liquid.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a T-type filter for conveying liquid materials. It can perform two filtrations through the lower and upper sections of the filter cylinder, resulting in a large filtration area, making it less prone to clogging and providing good filtration effect. At the same time, it can control the flow of liquid.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A T-type filter for conveying liquid materials includes an inlet pipe and an outlet pipe arranged opposite to each other. The pipe section between the inlet pipe and the outlet pipe extends upward to form an upper extension pipe, and the pipe section between the inlet pipe and the outlet pipe extends downward to form a lower extension pipe. A transverse partition is provided between the upper and lower extension tubes, and a filter cylinder is vertically inserted through the transverse partition. The upper end of the filter cylinder extends into the upper extension tube, and the lower end of the filter cylinder extends into the lower extension tube. An upper plug is installed at the upper end of the upper extension tube, and a lower plug is installed at the lower end of the lower extension tube.

[0008] Furthermore, the filter cylinder has filter mesh holes on its side wall, with the filter mesh holes located below the transverse partition being larger than those located above the transverse partition.

[0009] Furthermore, both the upper and lower plugs are equipped with sealing gaskets, and the two ends of the filter cylinder rest on the sealing gaskets respectively.

[0010] Furthermore, the upper plug is installed at the upper end of the upper protruding tube via a threaded connection, and the lower plug is installed at the lower end of the lower protruding tube via a threaded connection.

[0011] Furthermore, a sealing ring is installed at the through hole where the filter cartridge is mounted on the transverse partition.

[0012] Furthermore, the through-holes on the transverse partition where the filter cartridge is mounted extend upwards and downwards to form an extended sleeve.

[0013] Furthermore, a sliding sleeve is fitted inside the filter cylinder, and the outer wall of the sliding sleeve is in close contact with the inner wall of the filter cylinder; Furthermore, when the sliding sleeve is at the horizontal partition, the liquid flows normally. When the sliding sleeve slides to the bottom, it blocks the lower section of the filter cartridge, thus blocking the liquid flow.

[0014] Furthermore, the sliding sleeve is provided with a screw rod, which is fixedly connected to the inner wall of the sliding sleeve through a connecting rod, and the screw rod extends upward beyond the upper plug.

[0015] Furthermore, the screw is mounted on the upper plug via a threaded rotation, and a rotating head is installed at the upper end of the screw.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: A transverse partition is provided between the upper and lower extension pipes, and a filter cylinder is vertically inserted through the transverse partition. The upper end of the filter cylinder extends into the upper extension pipe, and the lower end of the filter cylinder extends into the lower extension pipe. The lower section of the filter cylinder has larger mesh openings, which serves as a pre-filtration function, while the upper section of the filter cylinder has smaller mesh openings, which serves as a fine filtration function. Moreover, the filter cylinder has a larger filtration area and is not easily clogged.

[0017] When the sliding sleeve is at the horizontal partition, the liquid flows normally. When the sliding sleeve slides to the bottom, it blocks the lower section of the filter cartridge, thus blocking the liquid flow and controlling the liquid flow interruption.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, this utility model provides a T-type filter for conveying liquid materials, including an inlet pipe 1 and an outlet pipe 2 arranged opposite to each other. The pipe section between the inlet pipe 1 and the outlet pipe 2 extends upward to form an upper extension pipe 4, and the pipe section between the inlet pipe 1 and the outlet pipe 2 extends downward to form a lower extension pipe 3.

[0023] A transverse partition 8 is provided between the upper extension tube 4 and the lower extension tube 3. A filter cylinder 7 is vertically inserted through the transverse partition 8. The upper end of the filter cylinder 7 extends into the upper extension tube 4, and the lower end of the filter cylinder 7 extends into the lower extension tube 3. An upper plug 6 is installed at the upper end of the upper extension tube 4, and a lower plug 5 is installed at the lower end of the lower extension tube 3.

[0024] The filter cylinder 7 has filter mesh holes on its side wall, and the filter mesh holes in the part below the transverse partition 8 are larger than the filter mesh holes in the part above the transverse partition 8.

[0025] Both the upper plug 6 and the lower plug 5 are provided with sealing gaskets 15, and the two ends of the filter cylinder 7 are respectively pressed against the sealing gaskets 15.

[0026] The upper plug 6 is installed at the upper end of the upper protruding pipe 4 by a threaded connection, and the lower plug 5 is installed at the lower end of the lower protruding pipe 3 by a threaded connection.

[0027] A sealing ring 10 is installed at the through hole of the filter cylinder 7 on the transverse partition 8.

[0028] The filter cylinder 7 is installed on the transverse partition 8, and the through hole extends upward and downward to form an extended sleeve 9.

[0029] The filter cylinder 7 is fitted with a sliding sleeve 11. The outer wall of the sliding sleeve 11 is in close contact with the inner wall of the filter cylinder 7. When the sliding sleeve 11 is at the transverse partition 8, the liquid flows normally. When the sliding sleeve 11 slides to the bottom, it blocks the lower section of the filter cylinder 7 and blocks the liquid flow.

[0030] The sliding sleeve 11 is provided with a screw 13, which is fixedly connected to the inner wall of the sliding sleeve 11 through a connecting rod 12. The screw 13 extends upward beyond the upper plug 6.

[0031] The screw 13 is mounted on the upper plug 6 by a threaded rotation, and a rotating head 14 is mounted on the upper end of the screw 13.

[0032] The specific working principle of this utility model: The liquid flows in from the inlet pipe 1 and from the lower section of the filter cylinder 7, and then flows out from the upper section of the filter cylinder 7. The filtration effect is enhanced by two filtrations. The lower section of the filter cylinder 7 has larger mesh size, which plays a role in pre-filtration, while the upper section of the filter cylinder 7 has smaller mesh size, which plays a role in fine filtration. Moreover, the filtration area is larger and it is not easy to clog.

[0033] Rotating the rotating head 14 can adjust the position of the sliding sleeve 11 up and down. When the sliding sleeve 11 is at the horizontal partition 8, the liquid flows normally. When the sliding sleeve 11 slides to the bottom, it blocks the lower section of the filter cylinder 7, thus blocking the liquid flow and controlling the liquid flow interruption.

[0034] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
