Description

Technical Field

[0001] The utility model relates to the technical field of titanium rod filters, in particular to a pulling and fixing device based on a titanium rod filter. Background Art

[0002] A titanium rod filter element is a filter made of a sintered titanium powder filter element, generally used for rough filtration or intermediate filtration. This filter element has the advantages of high precision, high temperature resistance, corrosion resistance, high mechanical strength, etc., and is widely used in the pharmaceutical industry. After the titanium rod filter element is used for a period of time, it will be blocked to a certain extent, manifested as a decrease in flow rate and an increase in the pressure at the front end of filtration. Usually, it needs to be pulled out from the cover body for cleaning. However, during the pulling process, the titanium rod filter element is likely to contact the cover body, and then the dust adhering to the titanium rod filter element is likely to fall off, which is likely to cause dust flying. At the same time, when the titanium rod filter element is placed back into the cover body, it is likely to collide with the opening edge of the cover body, which is likely to damage the titanium rod filter element, and then affect its filtration effect. Therefore, a pulling and fixing device based on a titanium rod filter is designed to facilitate avoiding the contact between the titanium rod filter element and the cover body during installation and disassembly, further ensuring the integrity of the titanium rod filter element and avoiding the situation of dust flying caused by touching during the disassembly process, and facilitating quick installation and disassembly.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment:

[0025] Please refer to Figure 1-7 , a pull-out fixator based on a titanium rod filter, including a fixed plate 1 installed with a plurality of titanium rod filter elements 2 and a cover body 3 covering the plurality of titanium rod filter elements 2 and detachably connected to the fixed plate 1. A plurality of groups of pull-out fixing structures are circumferentially installed on the fixed plate 1 outside the plurality of titanium rod filter elements 2. The tops of the plurality of groups of pull-out fixing structures are in a horizontal plane and higher than the tops of the plurality of titanium rod filter elements 2. The plurality of groups of pull-out fixing structures can play a guiding role when pulling the titanium rod filter elements 2 out from the plurality of titanium rod filter elements 2, and can lock and fix the overall structure after being sleeved. The pull-out fixing structure includes a rotating rod 6 rotatably connected to the fixed plate 1. An ear plate 7 is fixedly installed at the top of the rotating rod 6. A plurality of arc ear grooves 9 are circumferentially arranged at the top of the cover body 3. Clamping parts adapted to the arc ear grooves 9 and guiding sliding surfaces 8 slidably matched with the side walls of the titanium rod filter elements 2 in the vertical direction are symmetrically arranged on both sides of the ear plate 7. A rotation driving mechanism for driving the rotating rod 6 to rotate is arranged on the fixed plate 1. Further, the plurality of pull-out fixing structures are preferably arranged in three groups.

[0026] Specifically, the rotation drive mechanism includes a rotary knob 12 fixedly installed at the bottom of the rotating rod 6. A plurality of inner embedding grooves 11 adapted to the rotary knob 12 are circumferentially formed at the bottom of the fixed plate 1. The rotary knob 12 is embedded into the inner embedding groove 11. By means of the rotary knob 12, it is convenient to drive the rotating rod 6 to rotate. Through the cooperation of the inner embedding groove 11 and the rotary knob 12, it is convenient to integrally embed the rotary knob 12 into the fixed plate 1, so that the rotary knob 12 is not easily bumped.

[0027] Specifically, a through groove 10 is formed at the position of the arc ear groove 9 between the engaging portion and the guiding sliding surface 8. Through the arrangement of the through groove 10, the wind resistance during the filtering process and the plugging and unplugging process is reduced.

[0028] Specifically, a positioning ring 13 is fixedly connected to the inner bottom of the inner embedding groove 11. Two positioning grooves 14 are symmetrically arranged on the positioning ring 13. The two positioning grooves 14 are located on a radius line of the fixed plate 1. Through the positioning ring 13 and the two positioning grooves 14, it is convenient for the rotary knob 12 to quickly rotate the angle, so that the ear plate 7 quickly snaps the engaging surface into the arc ear groove 9 or makes the guiding sliding surface 8 and the inner side wall of the cover 3 in an arc surface, which is convenient for quick installation and disassembly.

[0029] Specifically, a pressing ring 4 is fixedly installed at the outer bottom of the cover 3. The pressing ring 4 is fixedly connected to the fixed plate 1 through bolts. By connecting the pressing ring 4 and the fixed plate 1, the sealing performance between the cover 3 and the fixed plate 1 is increased, and it is convenient for disassembly.

[0030] Specifically, a sealing clamping ring 5 which is in sealed sliding fit with the inner wall of the cover 3 is fixedly connected to the outside of the plurality of titanium rod filters 2 on the fixed plate 1. Through the arrangement of the sealing clamping ring 5, it is convenient to increase the sealing performance between the fixed plate 1 and the cover 3 and guide the cover 3, and the stability of the overall connection between the fixed plate 1 and the cover 3 is increased.

[0031] During use, during disassembly, the rotation drive mechanism drives the rotating rod 6 to rotate so that the engaging portion rotates out of the arc ear groove 9, and then the cover 3 is pulled out from above the plurality of titanium rod filters 2. During the pulling out process, through the sliding contact between the guiding sliding surface 8 and the inner wall of the cover 3, the cover 3 is stably pulled out vertically. After cleaning the plurality of titanium rod filters 2, the titanium rod filters 2 are buckled on the plurality of titanium rod filters 2 again, and then the rotation drive mechanism drives the rotating rod 6 to rotate, thereby driving the arc ear groove 9 to rotate until the engaging portion is inserted into the arc ear groove 9, and then the titanium rod filters 2 and the fixed plate 1 are locked by screwing.
