[0002] Veterinary drugs refer to substances (including drug feed additives) used to prevent, treat, diagnose animal diseases or purposefully regulate animal physiological functions. Titanium rod filters are one of the commonly used filtering equipment in the processing of veterinary drugs. Titanium rod filters are filters made of titanium powder sintered filter elements. They are generally used for coarse filtration or intermediate filtration. This filter element has the advantages of high precision, high temperature resistance, corrosion resistance, and high mechanical strength, and is widely used in the pharmaceutical industry.

[0003] The titanium rod filter elements in the existing titanium rod filters are mostly fixed with a threaded connection structure, and a plurality of titanium rod filter elements are evenly arranged in a titanium rod filter, and the positions of two adjacent titanium rod filter elements are close to each other. As a result, when the titanium rod filter element is disassembled and assembled, the twisting of the titanium rod filter element will be interfered by the titanium rod filter element next to it, and it cannot be twisted at a large angle, but only at a small angle. Not only is the twisting posture inconvenient, but the overall disassembly and assembly efficiency is low, which is not conducive to the installation and later replacement of the titanium rod filter element. Based on this, a titanium rod filter disassembly and assembly structure is provided. Utility Model Content

[0029] The quick-install component 3 includes a self-locking unit and an unlocking unit. When the titanium rod filter element 2 is installed on the filter element fixing plate 108, the self-locking unit is used to self-lock and fix the titanium rod filter element 2, and the unlocking unit is used to release the locking and fixing of the titanium rod filter element 2 by the self-locking unit, so as to realize the rapid disassembly of the titanium rod filter element 2;

[0030] The titanium rod filter element 2 includes a filter element body 201, a mounting head 202, and an annular groove 203;

[0031] The mounting head 202 is fixed to the top of the filter element body 201, and the annular groove 203 is integrally formed on the outside of the mounting head 202. The filter element fixing plate 108 is provided with a mounting hole 110 for the mounting head 202 to pass through.

[0032] The self-locking unit includes a fixed sleeve 301, a through hole 302, and a 7-shaped spring piece 303;

[0033] The fixed sleeve 301 is fixed to the top of the filter element fixing plate 108 and aligned with the mounting hole 110. The through hole 302 is opened on the outside of the fixed sleeve 301 and communicates with the inner cavity of the fixed sleeve 301. The 7-shaped spring piece 303 is fixed on the inside of the through hole 302 and extends to the inside of the fixed sleeve 301.

[0034] The 7-shaped spring piece 303 has an inclined surface structure in the plugging direction close to the installation head 202 and a horizontal straight surface structure in the plugging direction away from the installation head 202;

[0035] When the mounting head 202 passes through the mounting hole 110 and is inserted into the fixing sleeve 301, the inclined surface of the 7-shaped spring piece 303 is squeezed to realize the outward expansion of the 7-shaped spring piece 303. When the annular groove 203 is aligned with the 7-shaped spring piece 303, the 7-shaped spring piece 303 is reset and snapped into the annular groove 203 under the action of its own elastic force, so as to realize the installation and fixation of the filter element body 201.

[0036] The unlocking unit includes a lower pressing ring block 304;

[0037] The lower pressure ring block 304 is sleeved on the outside of the fixed sleeve 301, and the inclined surface structure of the 7-shaped spring piece 303 protrudes to the outside of the fixed sleeve 301. The lower pressure ring block 304 is distributed in the middle position between the filter element fixing plate 108 and the 7-shaped spring piece 303;

[0038] When the lower pressure ring block 304 approaches the 7-shaped spring piece 303 along the outer wall of the fixed sleeve 301 , it is used to squeeze the inclined surface of the 7-shaped spring piece 303 to expand the 7-shaped spring piece 303 toward the outer shape, thereby unlocking the 7-shaped spring piece 303 from the installation head 202 .

[0039] In this embodiment: It is necessary to add that: Figure 1 , 2 It is a schematic diagram of the inverted state of the device. In daily use, the upper head 106 is facing downward, the filter cartridge 101 is located above, and the filter cartridge 101 and the upper head 106 are respectively provided with a feed port and a discharge port. After the material enters the filter cartridge 101 from the feed port, it can be filtered through the titanium rod filter element 2 (it should be noted that the mounting head 202 is a hollow structure and is connected to the inner cavity of the filter element body 201, which is used to provide a flow path for the filtered material), and then discharged from the discharge port;

[0040] When replacing the titanium rod filter element 2, just turn the entire device over to Figure 1 state, then the contact eye screw 105 is locked to the second fixed connection member 107, then the upper head 106 can be disassembled, and then the filter element mounting plate 108 is taken out, at this time, the filter element mounting plate 108 drives multiple titanium rod filter elements 2 to be synchronously moved out of the filter cartridge 101, and then the titanium rod filter element 2 and the filter element mounting plate 108 can be disassembled, and the operation steps are as follows:

[0041] Push the lower pressure ring block 304 close to the 7-shaped spring piece 303, and the lower pressure ring block 304 will squeeze the part of the 7-shaped spring piece 303 protruding outside the solid sleeve 301, so that the 7-shaped spring piece 303 is forced to open outward. At this time, the lateral part of the 7-shaped spring piece 303 is away from the installation head 202 and the clamping state with the annular clamping groove 203 is released. At this time, the filter element body 201 is pulled away from the filter element mounting plate 108 to realize the disassembly operation;

[0042] When installing a new titanium rod filter element 2, it is only necessary to align the mounting head 202 with the mounting hole 110 and insert it. At this time, the mounting head 202 passes through the mounting hole 101 and enters the interior of the fixing sleeve 301. The mounting head 202 contacts and squeezes the inclined surface of the 7-shaped spring piece 303, so that the 7-shaped spring piece 303 is forced to open outward, so that the mounting head 202 can smoothly pass through the middle part of multiple 7-shaped spring pieces 303. When the annular groove 203 and the 7-shaped spring piece 303 are aligned, the 7-shaped spring piece 303 will reset and snap into the annular groove 203 under the action of its own elastic force, thereby realizing the installation and fixation of the titanium rod filter element 2 (it should be noted that: at this time, the filter element body 201 and the filter element mounting plate 108 are in a tightly fitted state);

[0043] The titanium rod filter element 2 can be quickly installed and disassembled by cooperating with the above multiple parts. Compared with the traditional threaded connection structure, it is not only more convenient to operate, but also more efficient in assembly and disassembly.

[0044] Please refer to Figures 2 to 4 The through opening 302 and the 7-shaped spring piece 303 are arranged in a plurality of circles around the fixed sleeve 301 as the center. The outer side of the bottom of the lower pressure ring block 304 is an arc surface structure, and a polygonal protrusion is formed on the outer side of the lower pressure ring block 304.

[0045] In this embodiment: by providing a plurality of 7-shaped spring pieces 303, sufficient locking force can be provided for the installation of the titanium rod filter element 2;

[0046] The arc surface structure on the outer side of the bottom of the lower pressing ring block 304 enables the lower pressing ring block 304 to better squeeze the 7-shaped spring piece 303;

[0047] The polygonal protrusion formed on the outer side of the lower pressure ring block 304 can facilitate the application of thrust to the lower pressure ring block 304 .

[0048] Please refer to Figures 2 to 4 The mounting holes 110 and the quick-install components 3 are arranged on a circle with the circumference of the filter element fixing plate 108 as the center. The top of the filter element fixing plate 108 is located in the middle of the multiple quick-install components 3 and is fixedly connected with a handle 109.
