Description

Technical Field

[0001] This application relates to the field of pesticide formulation filtration technology, and specifically discloses a filtration device for pesticide formulation production. Background Technology

[0002] In the process of pesticide formulation production and processing, in order to ensure the cleanliness of pesticide formulations and avoid clogging of the nozzles of pesticide spraying devices later, pesticide formulations need to be filtered to remove impurities. A pesticide formulation production filtration device is required when filtering pesticide formulations.

[0003] Existing pesticide formulation filtration devices include a filter barrel, a lid, a rotating shaft mounted inside the filter barrel, several circumferentially mounted stirring blades on the shaft, a drive motor mounted on the lid to drive the shaft, a feeding hopper mounted on the lid, a discharge pipe with a valve at the bottom of the filter barrel, and a removable filter screen installed inside the filter barrel. During pesticide filtration, the pesticide formulation enters the filter barrel through the feeding hopper. The drive motor, via the shaft, drives the stirring blades to agitate the pesticide formulation within the filter barrel. The filter screen filters impurities from the pesticide formulation. The filtered pesticide formulation is discharged from the filter barrel through the discharge pipe. However, the filtered impurities easily accumulate on the filter plate, causing blockage and affecting the filtration efficiency. Furthermore, the filter plate needs to be removed and cleaned, which is labor-intensive.

[0004] Therefore, the inventors have provided a filtration device for pesticide formulation production to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing filtration devices used in pesticide formulation production, impurities filtered out during the filtration process of pesticide formulations tend to deposit on the filter plate, causing filter plate blockage and affecting the filtration efficiency of pesticide formulations.

[0006] To achieve the above objectives, the basic solution of this utility model provides a filtration device for pesticide formulation production, including a filter barrel, a barrel cover, a rotating shaft coaxially rotatably connected inside the filter barrel, several stirring blades circumferentially fixed to the rotating shaft, a drive motor on the barrel cover for driving the rotating shaft, a feeding hopper on the barrel cover, and a discharge pipe at the bottom of the filter barrel. A first ring is rotatably connected inside the filter barrel below the rotating shaft, and a second ring is rotatably connected to the inner side of the first ring. A slag discharge pipe with a valve, located below the second ring, coaxially passes through the bottom of the filter barrel. The bottom of the filter barrel and the second ring are fixedly connected... The filter is equipped with a filter screen and several support rods for supporting the filter screen. The bottom of the filter screen is circumferentially wrapped around the top edge of the slag discharge pipe. A through hole is opened on one side of the filter barrel, and a water pump for supplying water into the through hole is fixed to the outside of the filter barrel. A water-passing annular groove communicating with the through hole is opened on the outer wall of the ring. A water spray plate with a surface that is attached to the filter screen and has several water spray holes is fixed to one side of the bottom of the ring. A water-passing support groove communicating with the water spray holes is opened in the water spray plate. A connecting water passage is also opened between the ring and the water spray plate to connect the water-passing annular groove and the water-passing support groove. A connecting rod is fixed between the rotating shaft and the ring.

[0007] The principle and effect of this basic scheme are as follows:

[0008] 1. Compared with the prior art, the pesticide formulation of this utility model is poured into the filter barrel through the feeding hopper, filtered through the filter screen inside the filter barrel, and discharged from the filter barrel through the discharge pipe after filtration. The pesticide formulation enters from the feeding port and exits from the discharge pipe at the same time.

[0009] 2. Compared with the prior art, the pesticide formulation of this utility model is poured into the filter barrel through the feeding hopper, and the drive motor is started. The drive motor drives the stirring blade to rotate through the rotating shaft, continuously stirring the unfiltered pesticide formulation in the filter barrel, thereby accelerating the filtration efficiency of the filter screen for the pesticide formulation.

[0010] 3. Compared with the prior art, this utility model also includes a scraper and a spray plate. The scraper removes impurities from the surface of the filter screen, and the water pump injects water into the water-passing ring groove through the through hole. The water in the water-passing ring groove passes through the connecting water passage and the water-passing support groove, and finally sprays out through the spray holes on the spray plate to wash the bottom surface of the filter screen and the inner wall of the filter barrel. This solves the problem that in the existing filtration devices used in pesticide formulation production, impurities are easily deposited on the filter plate during the filtration of pesticide formulations, causing the filter plate to become blocked and affecting the filtration efficiency of pesticide formulations.

[0011] Furthermore, the spray plate has a polyhedral structure, with several spray holes on each face communicating with the water channel. The spray plate is also pyramidal, with several spray holes on each face. The spray plate can not only rinse the filter screen but also the filter canister.

[0012] Furthermore, the stirring blades on the rotating shaft are divided into three layers, with adjacent layers of stirring blades arranged in an alternating vertical pattern. This alternating arrangement of adjacent layers of stirring blades further accelerates the flow of pesticide formulations and improves the filtration efficiency of pesticide formulations.

[0013] Furthermore, the free ends of the stirring blades are all in contact with the surface of the filter barrel. The contact between the free ends of the stirring blades and the surface of the filter barrel allows for the scraping off of impurities adhering to the filter barrel during the stirring process, thus cleaning the inner wall of the filter barrel.

[0014] Furthermore, a scraper for removing impurities from the filter screen surface is fixedly connected to the bottom of the rotating shaft. The scraper is inclined and at the same angle as the filter screen. The inclination angle of the scraper matches that of the filter screen, which facilitates the removal of impurities from the filter screen surface. The rotating shaft drives the scraper to rotate, cleaning the impurities on the filter screen surface and accelerating the filtration of pesticide formulations by the filter screen.

[0015] Furthermore, the scraper is equipped with several cleaning brushes that can be inserted into the filter screen. The cleaning brushes can extend into the filter screen for a more thorough cleaning. Attached Figure Description

[0021] A filtration device for pesticide formulation production, implementing, for example Figure 1 and Figure 2As shown: It includes a filter barrel 1, a barrel cover, a rotating shaft 2 coaxially installed inside the filter barrel 1, several stirring blades 3 circumferentially fixed on the rotating shaft 2, a drive motor 4 installed on the barrel cover for driving the rotating shaft 2 to rotate, a feeding hopper 5 installed on the barrel cover, and a discharge pipe 6 installed at the bottom of the filter barrel 1.

[0022] Specifically, the discharge pipe 6 is installed on the left side of the bottom of the filter barrel 1. The output shaft of the drive motor 4 passes through the barrel cover and is coaxially fixed with the rotating shaft 2. The rotating shaft 2 extends into the interior of the filter barrel 1, and the drive motor 4 is covered with a protective shell. The drive motor 4 drives the stirring blade 3 through the rotating shaft 2 to stir the pesticide preparation inside the filter barrel 1, thereby accelerating the filtration of the pesticide preparation by the filter screen 10.

[0023] A rotatable ring 8 is installed inside the filter bucket 1 below the rotating shaft 2. A ring 9 is installed inside the ring 8. A slag discharge pipe 7 with a valve is coaxially connected to the bottom of the filter bucket 1 and located below the ring 9. A water pump 14 for supplying water to the through hole is fixedly installed on the right side of the outer wall of the filter bucket 1. A water passage groove communicating with the through hole is opened on the outer wall of the ring 8. Specifically, the output end of the water pump 14 is connected to a water outlet pipe, which is connected to a water-passing annular groove through a through hole. The input end of the water pump 14 is connected to a water supply pipe. The inner wall of the filter barrel 1 has an annular groove one, and the inner wall of the circular ring 8 has an annular groove two. The circular ring 8 is installed through the annular groove one and can rotate around the axis of rotation. Annular gaskets are installed on the upper and lower sides of the annular groove one. The circular ring 8 and the annular groove one rotate and seal. The circular ring 9 is installed through the annular groove two. A base platform is coaxially fixed on the inner bottom surface of the filter barrel 1. A through hole is coaxially opened on the base platform. The slag discharge pipe 7 is inserted into the through hole. The top of the slag discharge pipe 7 is at the same height as the top surface of the base platform. Several support rods are circumferentially fixed on the base platform at one end and circumferentially fixed on the circular ring 9 at the other end. The several support rods support the filter screen 10, so that the filter screen 10 is not easily deformed during the filtration of pesticide formulations and will not affect the filtration effect.

[0024] A water spray plate 13 with a filter screen 10 attached to its surface and several water spray holes is fixedly installed on the bottom right side of the ring 8. A water channel is opened in the water spray plate 13, which is connected to the water spray holes. A water passage is also opened between the ring 8 and the water spray plate 13 to connect the water channel and the water channel. A connecting rod 11 is fixedly installed between the rotating shaft 2 and the ring 8.

[0025] In this embodiment, the spray plate 13 has a polyhedral structure. Each face of the spray plate 13 has several spray holes that communicate with the water channel. The spray plate 13 can not only rinse the filter screen 10, but also rinse the inner wall of the filter barrel 1. A scraper 12 for scraping off impurities from the surface of the filter screen 10 is fixedly installed at the bottom of the rotating shaft 2. The scraper 12 is inclined and the same as the inclination angle of the filter screen. The inclination angle of the scraper 12 is the same as that of the filter screen 10, which facilitates the scraping off of impurities from the surface of the filter screen 10. The rotating shaft 2 drives the scraper 12 to rotate and clean the impurities from the surface of the filter screen 10, thereby accelerating the filtration of pesticide formulations by the filter screen 10. Several cleaning brushes that can be inserted into the filter screen 10 are installed on the scraper 12. The cleaning brushes can be inserted into the filter screen 10 to clean it more thoroughly.

[0026] The stirring blades 3 are divided into three layers on the rotating shaft 2. The stirring blades 3 of adjacent layers are staggered and vertically distributed. The staggered and vertical distribution of the stirring blades 3 of adjacent layers can accelerate the flow of pesticide formulations and improve the filtration efficiency of pesticide formulations. The free ends of the stirring blades 3 are all in contact with the surface of the filter barrel 1. During the stirring process, the stirring blades 3 scrape off the impurities attached to the filter barrel 1 and clean the inner wall of the filter barrel 1. Four support legs are fixedly installed at the bottom of the filter barrel 1. The support legs are arranged in a rectangular shape. The support legs ensure the stability of the filter barrel 1 during operation and facilitate the discharge of the filtered pesticide formulations from the filter barrel 1.

[0027] In use, the drive motor 4 is started, and the pesticide formulation to be filtered is poured from the feeding hopper 5 into the filter barrel 1. It is filtered through the filter screen 10, and the filtered pesticide formulation is discharged from the discharge pipe 6. The pesticide formulation continuously enters from the feeding port and exits through the discharge pipe. The drive motor 4 drives the scraper 12 and stirring blade 3 to rotate via the rotating shaft 2. The stirring blade 3 stirs the pesticide formulation, improving the filtration efficiency. The scraper 12 cleans impurities from the surface of the filter screen 10, accelerating the filtration of the pesticide formulation. After all the pesticide formulation has been discharged from the discharge pipe 6, the [processing steps are missing]. The valve of the slag discharge pipe 7 is turned on, and the water pump 14 is started. The water pump 14 injects water into the water ring groove through the through hole. The water in the water ring groove is sprayed out from the spray hole of the spray plate 13 through the connecting water passage and the water support groove. The rotating shaft 2 drives the ring 8 to rotate through the connecting rod 11. The ring 8 drives the spray plate 13 to rotate, so that the spray plate 13 washes the impurities on the bottom surface of the filter screen 10 and the inner wall of the filter barrel 1. The wastewater from washing the impurities is discharged from the discharge pipe 6 until the impurities are washed clean. Then, the water pump 14 and the drive motor 4 are stopped. After drying for a period of time, the device can be used again.
