[0003] Although the aforementioned patent can achieve the filtration process of chemical raw materials, the filter holes are prone to clogging during the filtration process, which affects the filtration effect and may even cause the filtration process to stop. Furthermore, the device cannot filter impurities of different specifications, resulting in poor filtration performance.

[0004] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0005] The technical problem to be solved by this invention is as follows:

[0006] While existing technologies can achieve the filtration of chemical raw materials, the filtration process is prone to clogging of the filter pores, which affects the filtration effect and may even cause the filtration process to stop. Furthermore, existing technologies cannot filter impurities of different specifications, resulting in poor filtration performance.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A filtration device for indoxacarb production includes a first filtration mechanism for filtering fine impurities in indoxacarb granules, and a second filtration mechanism for filtering large volume impurities in indoxacarb granules is provided at the bottom of the first filtration mechanism.

[0009] The first filtration mechanism includes a first filter box, a first rotating shaft is rotatably arranged inside the first filter box, a number of first spiral blades are fixedly arranged on the outer surface of the first rotating shaft, a number of dust removal holes are opened through the surface of the first rotating shaft, the diameter of the dust removal holes is smaller than the diameter of the indoxacarb particles, and a dredging component is arranged inside the first rotating shaft to prevent the dust removal holes from being blocked.

[0010] The second filtration mechanism includes a second filter box fixedly installed at the bottom of the first filter box. A second rotating shaft is rotatably installed inside the second filter box. Several equally spaced second spiral blades are fixedly installed on the outer surface of the second rotating shaft. Several material guiding components for guiding indoxacarb granules are installed inside the second filter box. The material guiding components are located between adjacent second spiral blades. Several equally spaced filter holes are opened at the bottom of the second filter box. The diameter of the filter holes is adapted to the diameter of the indoxacarb granules.

[0011] Furthermore, the unblocking assembly includes several unblocking plates that are slidably disposed inside the first rotating shaft. A fixed seat is fixedly disposed at the middle of one end of the first rotating shaft. Several unblocking plates are arranged in a circular array outside the fixed seat and are fixedly disposed between the fixed seat and the fixed seat by a telescopic spring. Several unblocking columns are fixedly disposed on the side of the unblocking plate away from the telescopic spring, and several unblocking columns correspond one-to-one with several dust removal holes.

[0012] Furthermore, a drive shaft is provided inside the first rotating shaft. One end of the drive shaft extends to the outside of the first rotating shaft and is fixedly connected to the inner wall of the first filter box. A drive plate is fixedly provided on one side of the outer surface of the drive shaft, and the drive plate abuts against the inner side of one of the unblocking plates.

[0013] Furthermore, a feed inlet is provided on one side of the top of the first filter box, and a discharge outlet is provided on the other side of the bottom of the first filter box, with the discharge outlet extending into the interior of the second filter box.

[0014] Furthermore, a dust collector is fixedly installed at one end of the first filter box, and an exhaust fan is fixedly installed on one side of the dust collector. The input end of the exhaust fan is connected to the dust collector, and one end of the first rotating shaft extends into the interior of the dust collector.

[0015] Furthermore, a first motor is fixedly installed on the top of the first filter box, the output end of the first motor passes through the first filter box and is fixedly installed with a first bevel gear, and a second bevel gear that meshes with the first bevel gear is fixedly installed on the outer surface of the first rotating shaft.

[0016] Furthermore, the material guiding assembly includes a positioning seat fixedly disposed at the top of the interior of the second filter box, a material guiding shaft slidably disposed at the bottom of the positioning seat, a positioning shaft fixedly disposed at one end of the outer surface of the material guiding shaft, one end of the positioning shaft abutting against the side of one of the second spiral blades, and a return spring fixedly disposed between the material guiding shaft and the positioning seat.

[0017] Furthermore, a second motor is fixedly installed on the side of the second filter box near the discharge port, and the output end of the second motor passes through the second filter box and is fixedly connected to the second rotating shaft.

[0018] Furthermore, a first collection box is fixedly installed at the bottom of the second filter box, and a second collection box is fixedly installed on the side of the second filter box away from the second motor. The bottom of the filter hole extends into the interior of the first collection box, and an opening is provided on the side of the second filter box away from the second motor, extending into the interior of the second collection box.

[0019] The beneficial effects of this invention are:

[0020] In this invention, the first filtration mechanism allows indoxacarb granules to enter the first filter box through the feed inlet. A first motor controls the rotation of a first bevel gear, which in turn drives a second bevel gear to rotate a first rotating shaft. This causes several first spiral blades to convey the indoxacarb granules. During this conveying process, a fan, in conjunction with dust removal holes, adsorbs fine particulate impurities from the indoxacarb granules, ensuring their purity. The rotation of the first rotating shaft relative to the drive shaft causes the drive plate to alternately abut against several unblocking plates. This causes the unblocking plates to overcome the force of the telescopic springs and move away from the fixed base, allowing several unblocking columns to enter the dust removal holes for unblocking. This prevents fine impurities from clogging the dust removal holes, ensuring their dust removal effect. Furthermore, the unblocking achieved through the relative rotation of the drive shaft and the first rotating shaft reduces power input and lowers production costs.

[0021] The second filtration mechanism allows the dust-removed indoxacarb granules to enter the second filter box through the feed inlet. A second motor controls the rotation of the second rotating shaft, which, in conjunction with the second spiral blades, conveys the indoxacarb granules. During this conveying process, the indoxacarb granules are fed through the filter holes into the first collection box. Larger impurities are conveyed into the second collection box by the second spiral blades. The guide assembly breaks up the indoxacarb granules during conveying under the action of the guide shaft, improving the filtration effect. A reset spring, in conjunction with a positioning shaft, causes the guide shaft to move continuously with the rotation of the second spiral blades, further enhancing the guiding effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-5 The present invention provides a technical solution:

[0031] A filtration device for indoxacarb production includes a first filtration mechanism 1 for filtering fine impurities in indoxacarb granules, and a second filtration mechanism 2 for filtering large volume impurities in indoxacarb granules is provided at the bottom of the first filtration mechanism 1.

[0032] The first filtration mechanism 1 includes a first filter box 11, a first rotating shaft 12 is rotatably arranged inside the first filter box 11, a plurality of first spiral blades 13 are fixedly arranged on the outer surface of the first rotating shaft 12, a plurality of dust removal holes 121 are opened through the surface of the first rotating shaft 12, the diameter of the dust removal holes 121 is smaller than the diameter of the indoxacarb particles, and a dredging component 14 is arranged inside the first rotating shaft 12 to prevent the dust removal holes 121 from being blocked.

[0033] The second filtration mechanism 2 includes a second filter box 21 fixedly installed at the bottom of the first filter box 11. A second rotating shaft 22 is rotatably installed inside the second filter box 21. A plurality of equidistantly distributed second spiral blades 23 are fixedly installed on the outer surface of the second rotating shaft 22. A plurality of material guiding components 24 for guiding indoxacarb granules are installed inside the second filter box 21. The plurality of material guiding components 24 are located between adjacent second spiral blades 23. A plurality of equidistantly distributed filter holes 25 are opened at the bottom of the second filter box 21. The diameter of the filter holes 25 is adapted to the diameter of the indoxacarb granules.

[0034] The unblocking assembly 14 includes several unblocking plates 141 that are slidably disposed inside the first rotating shaft 12. A fixed seat 142 is fixedly disposed at the middle of one end of the first rotating shaft 12. Several unblocking plates 141 are arranged in a circular array outside the fixed seat 142 and a telescopic spring 143 is fixedly disposed between them and the fixed seat 142. Several unblocking columns 144 are fixedly disposed on the side of the unblocking plate 141 away from the telescopic spring 143. Several unblocking columns 144 correspond one-to-one with several dust removal holes 121.

[0035] The first rotating shaft 12 is provided with a drive shaft 145 inside. One end of the drive shaft 145 extends to the outside of the first rotating shaft 12 and is fixedly connected to the inner wall of the first filter box 11. A drive plate 146 is fixedly provided on one side of the outer surface of the drive shaft 145. The drive plate 146 abuts against the inner side of one of the unblocking plates 141.

[0036] The first filter box 11 has a feed inlet 111 on one side of the top and a discharge port 112 on the other side of the bottom. The discharge port 112 extends into the interior of the second filter box 21.

[0037] A dust collector 15 is fixedly installed at one end of the first filter box 11, and an exhaust fan 151 is fixedly installed on one side of the dust collector 15. The input end of the exhaust fan 151 is connected to the dust collector 15, and one end of the first rotating shaft 12 extends into the dust collector 15.

[0038] A first motor 16 is fixedly installed on the top of the first filter box 11. The output end of the first motor 16 passes through the first filter box 11 and is fixedly installed with a first bevel gear 17. A second bevel gear 18 that meshes with the first bevel gear 17 is fixedly installed on the outer surface of the first rotating shaft 12.

[0039] The first filtration mechanism 1 allows indoxacarb granules to enter the first filter box 11 through the feed inlet 111. The first motor 16 controls the rotation of the first bevel gear 17, which in turn drives the first rotating shaft 12 to rotate. This causes several first spiral blades 13 to convey the indoxacarb granules. During this conveying process, a fan 151, in conjunction with dust removal holes 121, adsorbs fine particulate impurities from the indoxacarb granules, ensuring their purity. The first rotating shaft 12... The rotation of the drive plate 146 relative to the drive shaft 145 causes the drive plate 146 to alternately abut against several unblocking plates 141. This causes the unblocking plates 141 to overcome the force of the telescopic spring 143 and move away from the fixed seat 142, allowing several unblocking columns 144 to enter the dust removal hole 121 to achieve unblocking. This prevents fine impurities from clogging the dust removal hole 121, ensuring the dust removal effect of the dust removal hole 121. Furthermore, the unblocking is achieved through the relative rotation of the drive shaft 145 and the first rotating shaft 12, reducing power input and lowering production costs.

[0040] The material guiding assembly 24 includes a positioning seat 241 fixedly disposed at the top of the inside of the second filter box 21. A material guiding shaft 242 is slidably disposed at the bottom of the positioning seat 241. A positioning shaft 243 is fixedly disposed at one end of the outer surface of the material guiding shaft 242. One end of the positioning shaft 243 abuts against the side of one of the second spiral blades 23. A return spring 244 is fixedly disposed between the material guiding shaft 242 and the positioning seat 241.

[0041] A second motor 26 is fixedly installed on the side of the second filter box 21 near the discharge port 112. The output end of the second motor 26 passes through the second filter box 21 and is fixedly connected to the second rotating shaft 22.

[0042] The bottom of the second filter box 21 is fixedly provided with a first collection box 27, and the side of the second filter box 21 away from the second motor 26 is fixedly provided with a second collection box 28. The bottom of the filter hole 25 extends into the interior of the first collection box 27, and the side of the second filter box 21 away from the second motor 26 has an opening that extends into the interior of the second collection box 28.

[0043] The second filtration mechanism 2 allows the dust-removed indoxacarb granules to enter the second filter box 21 through the feed port 112. The second motor 26 controls the rotation of the second rotating shaft 22, which, in conjunction with the second spiral blades 23, conveys the indoxacarb granules. During the conveying process, the indoxacarb granules are fed into the first collection box 27 through the filter holes 25. Large impurities are conveyed into the second collection box 28 by the second spiral blades 23. The guide assembly 24 disperses the indoxacarb granules under the action of the guide shaft 242 during the conveying process, improving the filtration effect of the indoxacarb granules. The reset spring 244, in conjunction with the positioning shaft 243, causes the guide shaft 242 to move continuously with the rotation of the second spiral blades 23, improving the guiding effect.

[0044] Working principle:

[0045] In use, indoxacarb granules enter the first filter box 11 through the feed inlet 111. The first motor 16 controls the rotation of the first bevel gear 17, which in turn drives the first rotating shaft 12 to rotate. This causes several first spiral blades 13 to convey the indoxacarb granules. During the conveying process, the exhaust fan 151, in conjunction with the dust removal holes 121, adsorbs fine particulate impurities in the indoxacarb granules. The rotation of the first rotating shaft 12 causes it to rotate relative to the drive shaft 145, thereby causing the drive plate 146 to alternately abut against several unblocking plates 141. This causes the unblocking plates 141 to overcome the force of the telescopic spring 143 and move away from the fixed seat 142, allowing several unblocking columns 144 to enter the dust removal holes 121 to achieve unblocking, preventing fine impurities from clogging the dust removal holes 121 and ensuring the dust removal effect of the dust removal holes 121.

[0046] After dust removal, the indoxacarb granules enter the second filter box 21 through the feed port 112. The second rotating shaft 22 is rotated by the second motor 26, which, together with the second spiral blades 23, conveys the indoxacarb granules. During the conveying process, the indoxacarb granules are fed into the first collection box 27 through the filter holes 25. Large impurities are conveyed into the second collection box 28 by the second spiral blades 23. The guide assembly 24 is set so that the indoxacarb granules are broken up by the guide shaft 242 during the conveying process, which improves the filtration effect of the indoxacarb granules. The reset spring 244, together with the positioning shaft 243, makes the guide shaft 242 move continuously with the rotation of the second spiral blades 23, which improves the guiding effect.

[0047] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
