Description

Technical Field

[0001] This utility model relates to the field of filtration and purification equipment technology, and in particular to an ethyl spinosad composite suspension filtration and purification device. Background Technology

[0002] Ethyl spinosad compound suspension is a highly effective and low-toxicity novel agricultural insecticide widely used in the control of pests in fruits, vegetables, and grains. Its formulation purity directly affects the stability of its efficacy and the safety of its use. If there are too many residual solid impurities in the suspension (such as undissolved active ingredient particles, adjuvant precipitates, etc.), it will not only reduce the insecticidal effect but may also clog spraying equipment and cause localized phytotoxicity to crops.

[0003] However, the existing equipment has obvious shortcomings: First, the single-stage filtration accuracy is limited, making it difficult to simultaneously trap impurities of different particle sizes, resulting in fine particles still remaining in the purified suspension; Second, filter residue easily accumulates on the surface of the filter media, requiring frequent shutdowns for cleaning, which seriously affects continuous production efficiency; Third, the equipment angle is fixed, resulting in insufficient contact between the material and the filter media, and "dead corners" easily forming in some areas, reducing filtration uniformity.

[0004] Therefore, those skilled in the art urgently need to develop an ethyl spinosad composite suspension filtration and purification device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ethyl spinosad composite suspension filtration and purification device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ethyl spinosad composite suspension filtration and purification device, including a base, on which two parallel support frames are fixedly mounted, and a purification tank is rotatably mounted between the two support frames. A feed pipe is provided on one side of the top of the purification tank, and a discharge pipe is provided on one side of the bottom of the purification tank. A drive box for controlling the rotation of the purification tank is provided on the support frame on the left side. The purification tank has a vertically placed drive shaft inside for rotation, and a rotating motor connected to the bottom of the drive shaft is provided. The purification tank has a primary filter assembly and a secondary filter assembly symmetrically arranged inside. Both the primary and secondary filtration components include a filter barrel and a filter plate. The filter barrel is fixedly connected to the drive shaft. Filter holes are evenly distributed on the filter barrel and filter plate. The filter barrel has a thin-walled frustum structure with a hollow central surface. A scraper is connected to the outer wall of the filter barrel.

[0007] Preferably, in the primary and secondary filtration components, the small central ends of the two filter barrels are positioned relatively close to each other, and the two filter plates are respectively located on the upper and lower sides of the two filter barrels.

[0008] Preferably, in the primary and secondary filtration components, the filter plate has a hollow circular structure in the middle, and a ring is provided on the side of the filter plate near the filter barrel, with the inner wall of the filter barrel fitting against the outer wall of the ring.

[0009] Preferably, a discharge pipe is connected to the side wall of the purification tank near the scraper, and a valve is provided on the discharge pipe.

[0010] Preferably, the top and bottom of the purification tank are both sloped structures, with the feed pipe located at the highest point of the top slope and the discharge pipe located at the lowest point of the bottom slope.

[0011] Preferably, the drive box is equipped with a drive motor, the purification tank is connected to the two support frames through a rotating shaft, and the output end of the drive motor is connected to the rotating shaft on the left side.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention significantly improves the purification quality of ethyl spinosad composite suspension by combining multi-stage progressive filtration with a dynamic cleaning structure. The primary and secondary filtration components employ filter pores of different sizes to create a gradient filtration effect, which can specifically trap impurities of different particle sizes, effectively reducing the content of solid impurities in the purified suspension and meeting the purity requirements of the formulation.

[0013] Meanwhile, the frustum structure of the filter barrel, combined with a scraper that rotates synchronously with the drive shaft, can clean the filter residue accumulated on the surface of the filter media in real time, reducing the risk of filter pore clogging and extending the continuous operation time of the equipment. The adjustable angle design and inclined inlet and outlet structure of the device further optimize filtration efficiency and ease of operation. The purification barrel can be flexibly adjusted in angle through the drive box, and with the inclined design of the top and bottom, the material can flow fully through the filter components under the combined action of gravity and centrifugal force, reducing the impact of "dead corners"; the filter plate and filter barrel are detachably connected, and with the automated discharge pipe, the process of cleaning filter residue and maintaining components is greatly simplified.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figures 1-4 This utility model provides an embodiment of an ethyl spinosad composite suspension filtration and purification device, including a base 1. The base 1 is welded from Q235 steel plate, and two parallel support frames 2 are fixed to its top by bolts. The support frames 2 are rectangular steel structures, and a purification tank 3 is rotatably mounted between the two support frames 2 via bearings. The purification tank 3 is made of 316 stainless steel, which is resistant to corrosion by organic solvents in the suspension. An inlet pipe 31 is welded to one side of its top, and an outlet pipe 32 is welded to one side of its bottom. Both the inlet pipe 31 and the outlet pipe 32 are equipped with control valves.

[0020] The support frame 2 on the left is equipped with a drive box 4 for controlling the rotation of the purification tank 3, which is used to control the rotation angle of the purification tank 3; the internal rotation of the purification tank 3 is provided with a vertically placed drive shaft 5, the bottom of the drive shaft 5 passes through the bottom of the purification tank 3 and is connected to a rotating motor 9 through a coupling.

[0021] The purification tank 3 has a primary filter assembly and a secondary filter assembly symmetrically arranged inside, forming a two-stage progressive filtration structure.

[0022] Both the primary and secondary filtration components include a filter barrel 6 and a filter plate 7. The filter barrel 6 is fixedly connected to the drive shaft 5 and rotates synchronously with the drive shaft 5. Both the filter barrel 6 and the filter plate 7 are made of 316 stainless steel and have filter holes evenly distributed on them. The filter holes of the primary filtration component are 80-120 mesh, and those of the secondary component are 150-200 mesh, which meets the requirements of gradient filtration.

[0023] The filter bucket 6 has a thin-walled frustum structure with a hollow central surface. The outer wall of the filter bucket 6 is connected to a scraper 61, which is made of polytetrafluoroethylene to avoid scratching the inner wall of the purification bucket 3.

[0024] Furthermore, in the primary and secondary filtration components, the small central ends of the two filter barrels 6 are positioned relatively close to each other, and the two filter plates 7 are respectively located on the upper and lower sides of the two filter barrels 6. The two filter plates 7 are connected to the upper and lower sides of the two filter barrels 6 by snap-fit, which facilitates disassembly and cleaning.

[0025] Furthermore, in the primary and secondary filtration components, the filter plate 7 has a hollow circular structure in the middle, and a ring 71 is provided on the side of the filter plate 7 near the filter barrel 6. The inner wall of the filter barrel 6 is in contact with the outer wall of the ring 71 to prevent unfiltered materials from flowing directly.

[0026] Furthermore, a discharge pipe 8 is connected to the side wall of the purification tank 3 near the scraper 61. A valve is installed on the discharge pipe 8. The top and bottom of the purification tank 3 are both sloping structures, and the feed pipe 31 is located at the highest point of the top sloping surface, which facilitates the free flow and dispersion of materials. The discharge pipe 32 is located at the lowest point of the bottom sloping surface, which ensures that the purified materials are completely discharged.

[0027] Furthermore, the drive box 4 is equipped with a drive motor. The purification tank 3 and the two support frames 2 are connected by a rotating shaft. The output end of the drive motor is connected to the rotating shaft on the left side through a reducer, which can drive the angle adjustment of the purification tank 3 to optimize the contact efficiency between the material and the filter components.

[0028] Working principle of this utility model: Ethyl spinosad compound suspension enters the purification tank 3 through the feed pipe 31 for primary filtration. Under the action of gravity, the suspension passes through the filter holes of the filter tank 6 and filter plate 7. Large particles of impurities are trapped at the top. Since the filter tank 6 in the primary filtration is inverted (the large circular surface of the filter tank 6 is on top), more suspension can be stored. The rotating motor 9 drives the drive shaft 5 to rotate the filter tank 6. Under the action of centrifugal force and gravity, the suspension passes through the filter holes of the filter tank 6.

[0029] The suspended medium after primary filtration flows downward and enters the secondary filtration assembly. The filter barrel 6 of the secondary filtration assembly is placed upright (the small circular surface of the filter barrel 6 is at the top). The suspended medium flows along the filter barrel 6 to the filter plate 7. While the rotating motor 9 drives the drive shaft 5 to rotate the filter barrel 6, the scraper 61 also rotates. The scraper 61 drives the rotation of the suspended medium, thereby accelerating filtration and further trapping fine impurities.

[0030] After passing through the secondary filtration, the purified suspension flows along the inclined surface at the bottom of the purification tank 3 and is finally discharged from the outlet pipe 32 located at the lowest point, completing the entire filtration and purification process. The angle of the purification tank 3 can be adjusted in real time by the drive box 4 to adapt to the filtration requirements of suspensions with different concentrations, ensuring full contact between the material and the filter components, and improving purification efficiency and effect.

[0031] When cleaning is required, water is added through the feed pipe 31. Impurities on the outside of the secondary filter barrel 6 are flushed onto the filter plate 7. The scraper 61 scrapes the fine impurities to the vicinity of the discharge pipe 8 to remove slag from the discharge pipe 8. Then, the purification barrel 3 is rotated 180° by the drive box 4. The primary filter barrel 6 rotates to the bottom, and the impurities inside are discharged from the discharge pipe 32 after being turned 180°.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
