Description

Technical Field

[0001] This utility model relates to the technical field of seed coating agent production and processing equipment, and in particular to a batching tank for preparing multi-target seed coating agents. Background Technology

[0002] Multi-target seed coating agents are compound agricultural seed coating agents that can simultaneously control various diseases and pests such as crop fungi, insect pests, and seedling diseases. During production, it is necessary to mix multiple materials such as active ingredients, film-forming agents, adjuvants, solvents, and color pastes. The material mixing and formulation process directly affects the mixing uniformity and purity of the seed coating agent.

[0003] Currently, traditional seed coating agent mixing tanks have significant shortcomings: Firstly, it only has a single stirring function, which means that material clumping and raw material impurities cannot be filtered online. When impurities mix into the finished drug solution, they will clog the filling pipeline and reduce the flatness of the seed coating.

[0004] Secondly, the mixing, filtering, and slag removal processes are independent of each other, requiring material transfer and step-by-step processing, making the batching process cumbersome and resulting in low production efficiency.

[0005] Third, the filter screen is very easy to stick to the medicine residue, and it is difficult to clean manually by opening the lid. Moreover, opening the lid to clean the tank can easily cause the medicine to volatilize and cause pollution.

[0006] Therefore, in view of the shortcomings of the existing technology, it is necessary to provide a mixing vessel for preparing multi-target seed coating agents to solve the shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0033] The present invention will be further described in conjunction with the following embodiments. Example 1, like Figure 1-5 As shown, a mixing vessel for preparing multi-target seed coating agents includes a mixing tank 1. The inner cavity of the mixing tank 1 is a combination cavity 2 of straight sections, which is smaller at the top and larger at the bottom, suitable for sedimentation and filtration of the drug solution. A closed feed inlet 3 is opened at the top of the mixing tank 1, and a slag outlet 4 is opened at a high position and a liquid outlet 5 is opened at a low position on the side wall. The slag outlet 4 and the liquid outlet 5 are respectively equipped with independent suction pumps 35. The slag outlet 4 is connected to the material slag tank 6 through the suction pump, and the liquid outlet 5 is connected to the liquid storage tank 7 through the suction pump, so as to realize independent and sealed collection of slag and liquid.

[0034] The mixing tank 1 is vertically equipped with a stirring and filtering integrated mechanism 8. The filter screen 9 is horizontally embedded in the inner wall of the mixing tank 1 through a circular frame 10, dividing the cavity into an upper floating stirring and filtering cavity 11 and a lower filtration and purification cavity 12. The upper end of the circular frame 10 is a concave slope, which facilitates the sliding and collection of the dregs. The bottom of the circular frame 10 is fixed with the filter screen 9, and the slope position is directly connected to the dregs outlet 4, which facilitates the dregs discharge operation.

[0035] The center of the filter screen 9 is sealed with a telescopic sleeve 13 via a dynamic sealing ring. The telescopic sleeve 13 has a built-in screw nut 15, which drives the ball screw 16. The bottom end of the ball screw 16 is limited and supported by a guide support seat 17, and the bottom end is coaxially fixed to a rotating shaft 39. The outside of the rotating shaft 39 is equipped with stirring blades A14 to homogenize the filtered liquid at a low speed and prevent the liquid from stratifying and settling.

[0036] The top of the ball screw 16 is connected to the top motor 19 via the coupling 18. The motor 19 drives the ball screw 16 to rotate and lift, and the outer component of the coupling to rotate. The outer side of the coupling 18 is fixedly connected to the annular fixing plate 20. The lower end of the annular fixing plate 20 is fixed to the rotating telescopic sleeve 21. The outer side of the sleeve is equidistantly arranged with stirring blades B22 to break up the clumps of the upper agent and mix various auxiliary raw materials at high speed.

[0037] The bottom fastener of the rotating telescopic sleeve 21 fixes the floating circular plate 23. The floating circular plate 23 is connected to the telescopic sleeve 13 by a bearing and can rotate freely relative to the telescopic sleeve 13. The bottom of the floating circular plate 23 is radially fixed with a cleaning component 24. The cleaning component 24 includes a cleaning brush 33 made of wear-resistant nylon and a forked pusher plate 34. During rotation, the cleaning brush 33 brushes the holes on the end face of the filter screen 9. The forked pusher plate 34 pushes the dregs to the filter screen 9 under the inclined surface of the circular frame 10 and automatically discharges the dregs with the suction pump.

[0038] The rotating telescopic sleeve 21 consists of a sleeve body 25, a splined bushing 27, and a pull-out bushing 28. The long spline groove 26 on the inner side of the sleeve body 25 cooperates with the splined bushing 27 to transmit torque. The short spline 31 at the bottom is inserted into the short spline groove 29 of the pull-out bushing 28 to realize torque transmission and adapt to vertical telescopic displacement. The limiting plate 32 limits the splined bushing 27 to prevent it from falling off. The bellows A36 and B37 respectively seal the telescopic gap of the rotating telescopic sleeve 21 and the telescopic sleeve 13. Together with the dynamic sealing ring, the cavity is sealed as a whole, preventing the volatilization and leakage of the agent.

[0039] The straight section combined cavity 2 is equipped with a reduced-diameter rotating inner wall 38. After the floating circular plate 23 is raised, it abuts against the rotating inner wall 38 to limit the maximum stroke of the agitator and adapt to different liquid level batching operations.

[0040] The working process of this utility model is as follows: various multi-target seed coating raw materials are put into the floating stirring and filtering chamber 11 through the feed inlet 3. The motor 19 is started, which drives the annular fixed plate 20, the rotating telescopic sleeve 21, and the stirring blade B22 to rotate and mix the materials, breaking up the raw material clumps. On the other hand, it drives the ball screw 16 to rotate, which in turn drives the screw nut 15 and the telescopic sleeve 13 to move vertically back and forth to match the liquid level in the chamber. After mixing, the medicine liquid penetrates the filter screen 9 and enters the lower filtration and purification chamber 12. Impurities are trapped above the filter screen 9. The bottom stirring blade A14 homogenizes and blends the filtered medicine liquid.

[0041] When the slag needs to be cleaned after the ingredients are prepared, the floating circular plate 23, which is installed between the drive telescopic sleeve 13 and the rotating telescopic sleeve 21, rotates and sinks. At the same time, the forked pusher plate 34 pushes the slag to facilitate the cleaning brush 33 to clean the holes of the filter screen 9. When the continuously sinking floating circular plate 23 presses against the inclined upper end face of the ring frame 10, the upper floating stirring chamber 11 and the lower filtration and purification chamber 12 are sealed.

[0042] The control system stops the motor 19, stops feeding raw materials, and the liquid in the floating stirring and filtering chamber 11 is completely emptied, so that the dregs can also be compacted onto the metal filter screen 9 by the floating circular plate 23. First, the seed coating agent is sucked out by the suction pump corresponding to the liquid outlet 5, and then the dregs on the filter screen 9 are sucked out by the suction pump corresponding to the dregs outlet 4. After the dregs are sucked out, the motor 19 is started to rotate the ball screw 16 in reverse, which lifts the floating circular plate 23 to reset, and the stirring and filtering operation can be restarted to realize the segmented closed liquid extraction and dregs discharge operation.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
