Technical Field

[0001] The utility model relates to the technical field of cyhalofop-butyl production, in particular to a suction filtration tank for cyhalofop-butyl production. Background Art

[0002] Vacuum filtration is also known as vacuum filtration. Vacuum filtration is widely used in various fields such as petroleum, chemical industry, food, and medicine. By connecting the vacuum equipment to the filtration tank, the pressure inside the filtration tank is reduced, thereby forming a pressure difference and accelerating the filtration process.

[0003] Cyhalofop-butyl is mainly used to control important grass weeds. Cyhalofop-butyl is highly effective against Leptochloa chinensis, has a certain control effect on young barnyard grass, and can also control crabgrass, Paspalum distachyon, Setaria viridis, Goosegrass, Alopecurus scabra, etc. It is ineffective against sedge weeds and broadleaf weeds. Cyhalofop-butyl needs to use a pressure reduction filter during the production process.

[0004] In the prior art, the filter is fixed on the filter tank. After a period of use, the filter may be clogged, which greatly reduces the filtration rate. Therefore, it needs to be frequently disassembled for cleaning, and the filtered residue cannot be collected conveniently and efficiently. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] Reference Figure 1-7 A suction filtration tank for cyfluthrin production includes a suction filtration tank body 1, a liquid storage tank 2 is installed on the top of the suction filtration tank body 1 through a bracket, the liquid storage tank 2 is used to store liquid raw materials, a suction pipe 101 is fixed on one side of the suction filtration tank body 1, the suction pipe 101 is connected to a vacuum device, and is used to provide a negative pressure environment during the suction filtration process, a drain pipe 104 is provided at the bottom of the suction filtration tank body 1, and the drain pipe 104 is used to discharge the filtered liquid, a liquid inlet pipe 102 is provided at the top of the suction filtration tank body 1, and a filtering mechanism 5 is also installed on the suction filtration tank body 1, and the liquid in the liquid storage tank 2 is filtered by the filtering mechanism 5 and then enters the suction filtration tank body 1.

[0027] Among them, the top of the liquid storage tank 2 is provided with a liquid introduction pipe 201, the bottom of the liquid storage tank 2 is provided with a liquid outlet pipe 202, the inside of the liquid outlet pipe 202 is movably installed with a lifting pipe 204, the bottom end of the lifting pipe 204 is fixed with an upper docking device 203, and the bottom end of the liquid storage tank 2 is fixed with a cylinder 205, and the output end of the cylinder 205 is fixed to the upper docking device 203;

[0028] The upper docking device 203 can be driven to move up and down by the cylinder 205, so as to be combined with and separated from the filtering mechanism 5.

[0029] Among them, a lower docking device 3 is provided above the suction filtration tank body 1, and the lower docking device 3 is connected to the liquid inlet pipe 102 through a bellows 301. A supporting vertical rod 303 is fixed to the bottom end of the lower docking device 3. The supporting vertical rod 303 is movably installed on the top of the suction filtration tank body 1 through an arc-shaped slide rail 302 and a slider mechanism. The top of the suction filtration tank body 1 is also horizontally movably installed with a limiter 4 through a first guide rod 402. A rectangular opening 401 is opened on the limiter 4. The supporting vertical rod 303 movably penetrates the limiter 4 through the rectangular opening 401. A first return spring 403 is installed on the outside of the first guide rod 402;

[0030] The lower docking device 3 can move along the arc-shaped slide rail 302, and during the movement, it will push the limiter 4 to move, thereby squeezing the first return springs 403 on both sides of the limiter 4. When the lower docking device 3 is not subjected to external force, the first return spring 403 will push the lower docking device 3 to move to its original position.

[0031] The filter mechanism 5 includes a fixed vertical rod 512, a first rotating vertical tube 501 is arranged outside the fixed vertical rod 512, the first rotating vertical tube 501 is driven to rotate by a rotating motor, a second rotating vertical tube 504 is installed on the top of the first rotating vertical tube 501 through a second guide rod 502 for lifting and lowering, a second return spring 503 is installed on the second guide rod 502, a horizontally arranged connecting shaft 506 is rotatably installed on both sides of the second rotating vertical tube 504, a filter 507 is fixed on one end of the connecting shaft 506 away from the second rotating vertical tube 504, and the top and bottom ends of the filter 507 are respectively provided with structures for plugging and matching with the upper docking device 203 and the lower docking device 3;

[0032] When the second return spring 503 is squeezed, the second rotating vertical tube 504 can be lifted and lowered relative to the first rotating vertical tube 501, and when the rotating motor drives the first rotating vertical tube 501 to rotate, the second rotating vertical tube 504 will also rotate accordingly, thereby driving the two filters 507 to change positions. When one of the filters 507 moves between the upper docking connector 203 and the lower docking connector 3, it can be docked to perform filtering. When it is necessary to clean the filter 507 and discharge the filter residue inside the filter 507, it is only necessary to switch the positions of the two filters 507, and then move the other new filter 507 to the filtering position, and then continue to use it, which can effectively improve the filtering and cleaning efficiency.

[0033] The top of the fixed vertical rod 512 penetrates the first rotating vertical tube 501 and the second rotating vertical tube 504 and extends to the top of the second rotating vertical tube 504. The top of the fixed vertical rod 512 is fixed with an arc-shaped rack 505 on the side away from the suction filtration tank body 1. The outer side of the connecting shaft 506 is fixed with a gear 508, and the connecting shaft 506 is meshed with the gear 508.

[0034] When the filter to be cleaned moves to the side away from the filtration tank body 1, the gear 508 will move along the arc-shaped rack 505, thereby driving the filter 507 to flip over. The opening on the side of the filter 507 corresponding to the upper docking device 203 is larger. When this side is opened downward, the filter residue can be automatically poured out and fall into the filter residue storage device for collection, effectively improving the efficiency of discharging the filter residue.

[0035] Among them, right-angle connecting rods 509 are fixed on both sides of the second rotating vertical tube 504 near the connecting shaft 506, and a clamping block 510 is fixed at the bottom end of the right-angle connecting rod 509. A limiting groove 511 is fixed at the bottom end of the clamping block 510. A limiting cross bar 304 is fixed on one side of the supporting vertical rod 303 near the fixed vertical rod 512. The limiting cross bar 304 corresponds to the limiting groove 511. A limiting pressure rod 305 is also fixed on the top of the filtration tank body 1. The limiting pressure rod 305 is in a semi-arc shape near the lower docking device 3.

[0036] In order to ensure efficient docking between the filter 507 and the lower docking device 3, when the filter 507 to be docked moves to a position close to the lower docking device 3, the horizontal portion of the right-angle connecting rod 509 first contacts the limiting pressure rod 305, thereby being pressed downward during the continued rotation, so that the second rotating vertical tube 504 moves downward. During the downward movement, when the filter 507 is aligned with the lower docking device 3, the limiting cross bar 304 will be stuck in the limiting groove 511, thereby ensuring that the lower docking device 3 will move along the arc slide rail 302 and remain aligned with the filter 507 during the continued movement of the filter 507. , and finally the docking is completed. At this time, the control cylinder 205 drives the upper docking device 203 to move downward and dock with the filter 507 to complete the docking. When the filter residue needs to be cleaned and discharged after filtering for a period of time, it is only necessary to continue to drive the filter 507 to move. Due to the curvature of the limiting pressure rod 305 and the elastic force of the second reset spring 503, the filter 507 will gradually move downward and separate from the lower docking device 3. Finally, when the limiting cross bar 304 is separated from the limiting groove 511, the lower docking device 3 will follow the limiter 4 to move and reset, thereby completing the automatic separation, which not only improves the filtering efficiency, but also ensures the safety and convenience of operation.
