Description

Technical Field

[0001] This utility model belongs to the field of biological pesticide technology, and in particular relates to a microbial pesticide formulation filtration device. Background Technology

[0002] Biological pesticides refer to preparations that use living organisms such as fungi, bacteria, insect viruses, genetically modified organisms, natural enemies, or their metabolites such as pheromones, auxins, sodium naphthaleneacetate, 2,4-D, etc., to kill or inhibit agricultural pests. They are also known as natural pesticides, which are non-chemically synthesized, derived from natural chemical substances or living organisms, and have the effects of bactericidal and insecticidal pesticides.

[0003] During the production and processing of microbial pesticides, the pesticide solution contains a certain amount of insoluble impurities, requiring filtration. However, most existing filtration devices tend to accumulate residues on the filter screen, causing blockage and affecting filtration efficiency. Furthermore, commercially available filtration devices typically only perform one filtration of the microbial pesticide solution, which may result in incomplete filtration. Therefore, it is necessary to design a microbial pesticide formulation filtration device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a microbial pesticide formulation filtration device with the advantages of double-layer filtration and backwashing, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A microbial pesticide preparation filtration device includes a filter tank, a coarse filter component, and a fine filter component. The coarse filter component and the fine filter component are both installed in the inner cavity of the filter tank. The coarse filter component is located on top of the fine filter component. A sealing cover is installed on the top of the filter tank. A support leg is fixedly installed on the bottom of the filter tank. A liquid outlet pipe is provided at the bottom of the filter tank. A rinsing component is installed in the inner cavity of the filter tank. The fine filter component is rinsed by the rinsing component. A drain pipe that works in conjunction with the rinsing component is installed on the surface of the filter tank.

[0006] Furthermore, the fine filter assembly includes a fixed plate fixedly installed at the lower end of the inner cavity of the filter tank. Four fine filter cartridges extending to the bottom of the fixed plate are rotatably connected to the top of the fixed plate. The four fine filter cartridges are arranged in a ring on the top of the fixed plate. The inner cavity of the fine filter cartridges is connected to the inner cavity at the bottom of the fixed plate. A rotating block is rotatably connected to the top of the fine filter cartridges. The coarse filter assembly is placed on top of the rotating block. Four support tubes are fixedly installed on the top of the fixed plate. The four support tubes are located next to the four fine filter cartridges respectively. The top of the support tubes extends to the top of the coarse filter assembly and is threaded with a nut.

[0007] Furthermore, the coarse filter assembly includes a mounting plate that is detachably installed above the inner cavity of the filter tank. The top of the mounting plate is threaded with four coarse filter cylinders, which are arranged in a ring on the top of the mounting plate. The inner cavity of the coarse filter cylinders is connected to the inner cavity at the bottom of the mounting plate. A sealing ring is installed on the surface of the mounting plate and fits against the inner cavity surface of the filter tank.

[0008] Furthermore, the rinsing assembly includes an annular tube installed on the outer surface of the filter tank, the annular tube communicating with the inner cavity of the support tube, and the surface of the support tube having spray holes for use with the fine filter cartridge.

[0009] Furthermore, a rotating rod is rotatably connected to the center of the top of the fixed plate, a drive gear is fixedly installed on the surface of the rotating rod, a gear is fixedly installed on the top of the fine filter cartridge, the rotating block is rotatably connected to the top of the gear, and the drive gear meshes with four gears respectively.

[0010] Furthermore, a square insert is fixedly installed on the top of the rotating rod, and a rotating column extending to the outside is rotatably connected to the inner cavity of the sealing cover. A slot for cooperating with the square insert is opened at the bottom of the rotating column, and a motor is fixedly installed on the top of the sealing cover. The output shaft of the motor and the rotating column are connected by a belt pulley.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model achieves double-layer filtration of microbial pesticide solutions by combining coarse and fine filtration components, thereby improving the filtration effect. At the same time, it is combined with a rinsing component to rinse and remove contaminants from the fine filtration component, thereby improving the filtration efficiency of the fine filtration component.

[0013] 2. This utility model uses the rotation rod, drive gear and gear in combination to drive four fine filter cartridges to rotate synchronously on the top of the fixed plate, which facilitates the water spray hole in the support tube to completely wash the surface of the fine filter cartridges and avoids the fine filter cartridges being incompletely washed due to the relatively fixed support tube.

[0014] 3. This utility model, through the setting of the support tube, can be used as a water pipe to rinse the fine filter cartridge, and can also be used as an installation tube to facilitate the user to fix and install the installation plate.

[0015] 4. By setting a sealing ring, this utility model can improve the sealing performance between the mounting plate and the inner cavity of the filter tank after the mounting plate is installed, and prevent the microbial pesticide solution from flowing into the fine filter assembly from the gap between the mounting plate and the inner cavity of the filter tank.

[0023] In the following description, embodiments of the microbial pesticide formulation filtration device of the present invention will be described with reference to the accompanying drawings.

[0024] Figure 1-4This invention illustrates a microbial pesticide formulation filtration device according to an embodiment of the present invention. It includes a filter tank 1, a coarse filter assembly 2, and a fine filter assembly 3. Both the coarse filter assembly 2 and the fine filter assembly 3 are installed inside the filter tank 1. Specifically, the coarse filter assembly 2 includes a detachable mounting plate 21 installed above the inner cavity of the filter tank 1. Four coarse filter cylinders 22 are threadedly connected to the top of the mounting plate 21. The four coarse filter cylinders 22 are arranged in a ring on the top of the mounting plate 21. The inner cavity of the coarse filter cylinders 22 communicates with the inner cavity at the bottom of the mounting plate 21. A sealing ring 23 is installed on the surface of the mounting plate 21, fitting snugly against the inner surface of the filter tank 1. The sealing ring 23 improves the sealing between the mounting plate 21 and the inner cavity of the filter tank 1 after installation, preventing the microbial pesticide solution from flowing into the fine filter assembly 3 through the gap between the mounting plate 21 and the inner cavity of the filter tank 1. The coarse filter assembly 2 is located on top of the fine filter assembly 3. Specifically, the fine filter assembly 3 includes a fixed plate 31 fixedly installed at the lower end of the inner cavity of the filter tank 1. The top of the fixed plate 31 is rotatably connected to four fine filter cylinders 32 extending to the bottom of the fixed plate 31. The four fine filter cylinders 32 are arranged in a ring on the top of the fixed plate 31. The inner cavity of the fine filter cylinder 32 is connected to the inner cavity at the bottom of the fixed plate 31. The top of the fine filter cylinder 32 is rotatably connected to a rotating block 33. The coarse filter assembly 2 is placed on top of the rotating block 33. The top of the fixed plate 31 is fixedly installed with four support pipes 4. The four support pipes 4 are located next to the four fine filter cylinders 32 respectively. The top of the support pipes 4 extends to the top of the coarse filter assembly 2 and is threaded with nuts 5. The top of the filter tank 1 is equipped with a sealing cover 6. The bottom of the filter tank 1 is fixedly installed with support legs 10. The bottom of the filter tank 1 is provided with a liquid outlet pipe 14.

[0025] The flushing assembly is installed inside the filter tank 1 and is used to flush the fine filter element 3. The surface of the filter tank 1 is equipped with a drain pipe that works in conjunction with the flushing assembly. Specifically, the flushing assembly includes an annular pipe 9 installed on the outer surface of the filter tank 1. The annular pipe 9 is connected to the inner cavity of the support pipe 4. The surface of the support pipe 4 is provided with spray holes that work in conjunction with the fine filter element 32. The support pipe 4 can be used as a water pipe to flush the fine filter element 32, and it can also be used as an installation pipe to facilitate the user to fix and install the installation plate 21.

[0026] Specifically, a rotating rod 7 is rotatably connected to the center of the top of the fixed plate 31, and a drive gear 8 is fixedly installed on the surface of the rotating rod 7. A gear 34 is fixedly installed on the top of the fine filter cartridge 32, and a rotating block 33 is rotatably connected to the top of the gear 34. The drive gear 8 meshes with the four gears 34 respectively. Through the coordinated use of the rotating rod 7, the drive gear 8, and the gears 34, the four fine filter cartridges 32 can be driven to rotate synchronously on the top of the fixed plate 31, thereby facilitating the complete rinsing of the surface of the fine filter cartridges 32 by the water spray holes in the support pipe 4, and avoiding incomplete rinsing of the fine filter cartridges 32 due to the relatively fixed support pipe 4. Specifically, a square insert 11 is fixedly installed on the top of the rotating rod 7, and a rotating column 12 extending to the outside is rotatably connected to the inner cavity of the sealing cover 6. The bottom of the rotating column 12 has a slot for cooperating with the square insert 11. A motor 13 is fixedly installed on the top of the sealing cover 6, and the output shaft of the motor 13 is connected to the rotating column 12 by a belt pulley.

[0027] Working Principle: In use, the user feeds the heat-inactivated microbial pesticide solution through the inlet pipe in the sealed cover 6 to the top of the mounting plate 21. At this time, the microbial pesticide solution is initially filtered by the coarse filter 22. The filtered solution enters the top of the fixed plate 31 from the inner cavity of the coarse filter 22. Impurities from the filter feed are temporarily stored at the top of the mounting plate 21. Subsequently, the microbial pesticide solution is filtered again by the fine filter 32. The filtered solution passes through the inner cavity of the fine filter 32 into the bottom of the inner cavity of the filter tank 1 and is discharged from the inner cavity of the outlet pipe 14. The cooperation of the coarse filter assembly 2 and the fine filter assembly 3 achieves double-layer filtration of the microbial pesticide solution, improving the filtration effect. After the device has been used for a certain period of time, water is pumped into the annular pipe 9, and the motor is simultaneously controlled and turned on. 13. At this time, the motor 13 will drive the rotating column 12 to rotate, thereby driving the square insert block 11, the rotating rod 7 and the drive gear 8 to rotate, which in turn drives the gear 34 and the fine filter cartridge 32 to rotate, so that the fine filter cartridge 32 rotates between the mounting plate 21 and the fixed plate 31. With the help of water sprayed from the water spray hole in the support pipe 4, the surface of the fine filter cartridge 32 is washed and cleaned. The washed-off sewage is discharged from the drain pipe in the filter tank 1, which improves the filtration efficiency of the fine filter assembly 3. It should be noted that since the drain pipe is located on the rear side of the filter tank 1, it is not shown in the schematic diagram. The drain pipe is set at the same height as the fixed plate 31 to facilitate the full discharge of sewage. When the mounting plate 21 in the coarse filter assembly 2 becomes blocked and affects the filtration efficiency, the sealing cover 6 can be removed and the mounting plate 21 can be taken out for cleaning.

[0028] In summary, this microbial pesticide formulation filtration device achieves double-layer filtration of the microbial pesticide solution through the cooperation of the coarse filter component 2 and the fine filter component 3, thereby improving the filtration effect. At the same time, the rinsing component is used to rinse and remove contaminants from the fine filter component 3, thereby improving the filtration efficiency of the fine filter component 3.
