[0002] Mepiquat is a new type of plant growth regulator that has a good systemic conduction effect on plants. It can promote plant reproductive growth, inhibit the crazy growth of stems and leaves, control lateral branches, shape ideal plant shapes, increase the number and vitality of roots, increase fruit weight, and improve quality. In order to improve the regulatory efficiency of mepiquat on plants, it is usually necessary to filter mepiquat during the production process.

[0003] The existing patent with announcement number CN220214118U discloses a vacuum filter, including a base, on which a filter body is fixedly installed, a plurality of support rods are fixedly arranged at equal intervals on the base, a workbench is fixedly arranged on the top of the support rods, and a raw liquid barrel is fixedly arranged at the bottom of the workbench; a filter cartridge is fixedly connected and installed at the bottom of the raw liquid barrel, the bottom of the filter cartridge is connected to the filter body, an opening is provided on the filter cartridge, and a sealing cover is hinged on one side of the opening; a fixing ring is fixedly installed in the sealing cover, and a filter element is installed on the fixing ring; a plurality of buckles are installed on the side of the sealing cover away from the filter cartridge, and a plurality of supports are installed on the side of the filter cartridge close to the buckle, a butterfly screw is rotatably arranged on the support, and the butterfly screw is engaged with the buckle.

[0004] When the filter element of the above-mentioned suction filter is replaced, the butterfly screw is unscrewed to make the butterfly screw disengage from the inner wall of the buckle. Then the sealing cover is rotated, and the filter element is taken out from the inside of the filter cartridge through the fixing ring, thereby completing the replacement of the filter element.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1: Figure 1-Figure 4 As shown, the technical solution adopted by the utility model is as follows: a vacuum filtration device for producing mepiquat, comprising a connecting seat 2, and a plurality of supporting legs 1 are fixedly arranged at the bottom of the connecting seat 2.

[0026] The top of the connection seat 2 is fixedly provided with a suction filter body 3, and a plurality of support rods 4 are fixedly provided at equal intervals on the top of the connection seat 2. The tops of the support rods 4 are fixedly connected with the same raw liquid tank 5, and the raw liquid tank 5 is located directly above the suction filter body 3. A connecting ring 9 is provided between the raw liquid tank 5 and the suction filter body 3.

[0027] The frame composed of the connecting seat 2, the suction filter body 3, the support rod 4, the raw liquid tank 5 and the connecting ring 9 specifically presents an hourglass shape.

[0028] The inner wall of the connecting ring 9 is slidably matched with the lower end of the raw liquid tank 5 and the upper end of the suction filter body 3. It is ensured that the connecting ring 9 can slide on the raw liquid tank 5 and the suction filter body 3.

[0029] The inner wall of the connecting ring 9 is fixedly provided with a sealing ring 17, the lower end of which is inwardly retracted, and the bottom of the sealing ring 17 is slidably connected to the top of the suction filter body 3, and the sealing ring 17 is also used to support the connecting ring 9. The inner wall of the suction filter body 3 is fixedly provided with a retaining ring 7, and a detachable filter element 8 is movably installed on the retaining ring 7, and the circumferential surface of the filter element 8 is in contact with the inner wall of the suction filter body 3.

[0030] A clamping piece is arranged on the connecting ring 9, and a limit adjustment component cooperating with the clamping piece is arranged on the raw liquid tank 5 and the suction filter body 3.

[0031] The clamping member comprises a plurality of upper clamping strips 12 which are fixedly arranged at equal distances on the top of the connecting ring 9 , and a plurality of lower clamping strips 15 are fixedly arranged on the bottom of the connecting ring 9 .

[0032] The limit adjustment assembly includes a second buckle 13 and a first buckle 14, both of which are fixedly arranged on the outer surface of the raw liquid tank 5, and the first buckle 14 is located directly above the second buckle 13. Both of the first buckle 14 and the second buckle 13 correspond to the number of the upper clamping strip 12 and slide with the upper clamping strip 12. A plurality of third buckles 16 are fixedly arranged on the outer surface of the suction filter body 3, and the third buckles 16 correspond to the number of the lower clamping strip 15 and slide with the lower clamping strip 15.

[0033] The ends of the upper clamping strip 12 and the lower clamping strip 15 are both triangular, and the upper clamping strip 12 and the lower clamping strip 15 themselves have a certain elasticity, specifically a rubber material. The clamping strip can be clamped in the corresponding buckle by sliding, so as to limit and fix the connecting ring 9, which is convenient for replacing the filter element 8.

[0034] A connecting rod 10 is fixedly arranged on the inner wall of the connecting ring 9, and a baffle 11 is fixedly arranged on the connecting rod 10. The baffle 11 is in a truncated cone shape. A guide member 6 is fixedly arranged on the inner wall of the raw liquid tank 5, and the lower end of the guide member 6 is arranged to be inwardly retracted, and a discharge port is provided on the guide member 6.

[0035] The discharge port is matched with the baffle plate 11. When the filter element 8 is replaced, the baffle plate 11 is driven to slide by the sliding connecting ring 9, and the baffle plate 11 blocks the discharge port on the guide member 6, thereby preventing the liquid in the original liquid tank 5 from flowing out.

[0036] A vacuum tube 18 is connected to the suction filter body 3 , and a discharge pipe 19 is connected to the bottom of the suction filter body 3 .

[0037] Working principle of the first embodiment: During operation, the external vacuum pump is connected to the suction filter body 3 through the vacuum pipe 18 .

[0038] Start the vacuum pump to extract the air in the suction filter body 3. At the same time, pour the prepared methylpiperidinium production stock solution into the stock solution tank 5.

[0039] As the air pressure in the suction filter body 3 decreases, the stock solution is sucked into the suction filter body 3, accelerating the inflow speed of the stock solution. The stock solution flows out from the discharge port through the guidance of the guide member 6, and the flow direction of the stock solution is disrupted by the blocking of the baffle 11, thereby increasing the mixing degree of various raw materials in the stock solution and improving the production efficiency of mepiquat.

[0040] After being disrupted by the baffle 11, the raw liquid will flow to the filter element 8 below, and will flow into the suction filter body 3 after being filtered by the filter element 8. At this time, the sealing ring 17 can prevent the raw liquid from flowing out from the connecting ring 9. The filtered raw liquid can be discharged from the discharge pipe 19.

[0041] When the filter element 8 needs to be replaced, the connecting ring 9 is pushed upwards. The ends of the upper clamping strip 12 and the lower clamping strip 15 on the connecting ring 9 will be squeezed and deformed, so that the lower clamping strip 15 is disengaged from the third buckle 16, and the upper clamping strip 12 is clamped into the second buckle 14.

[0042] When the connecting ring 9 slides upward, the sealing ring 17 also slides upward to prevent the original liquid from flowing out when the connecting ring 9 slides. When the upper clamping strip 12 is engaged with the second clamping buckle 14, the lower end of the connecting ring 9 has already been separated from the upper end of the suction filter body 3, and there is a certain distance between the two. Then, the filter element 8 is removed from the retaining ring 7, and the filter element 8 is taken out and replaced by using the distance between the connecting ring 9 and the suction filter body 3.

[0043] At the same time, when the connecting ring 9 slides upward, the baffle 11 will move to the discharge port of the guide member 6 to block the discharge port to prevent the original liquid from flowing out when the filter element 8 is replaced.

[0044] Embodiment 2: Figure 5As shown, compared with the first embodiment, the movement mode of the connecting ring 9 is changed in this embodiment. The lower end of the raw liquid tank 5 is provided with an upper threaded section 20, and the upper end of the suction filter body 3 is provided with a lower threaded section 23. The upper end of the inner wall of the connecting ring 9 is provided with a first inner threaded section 21, and the lower end of the inner wall of the connecting ring 9 is provided with a second inner threaded section 22. The upper threaded section 20 is threadedly matched with the first inner threaded section 21, and the lower threaded section 23 is threadedly matched with the second inner threaded section 22.

[0045] Working principle of the second embodiment: when the filter element 8 needs to be replaced, only the connecting ring 9 needs to be rotated.

[0046] The connecting ring 9 rises under the cooperation of the first internal thread section 21 and the upper thread section 20 and the second internal thread section 22 and the lower thread section 23 until the baffle 11 contacts and blocks the discharge port of the guide member 6 to prevent the original liquid from flowing out when the filter element 8 is replaced.

[0047] When the baffle 11 completely blocks the discharge port of the guide member 6, the lower thread section 23 has already been separated from the second internal thread section 22, the lower end of the connecting ring 9 has already been separated from the upper end of the suction filter body 3, and there is a certain distance between the lower end of the connecting ring 9 and the lower end of the suction filter body 3. Then, the filter element 8 is removed from the baffle ring 7, and the filter element 8 is taken out and replaced by using the distance between the connecting ring 9 and the suction filter body 3.
