Description

Technical Field

[0001] The present application relates to the technical field of stirring devices, and in particular to a two-way stirring pesticide suspension preparation device. Background Art

[0002] Pesticide suspension concentrate is a viscous and flowable suspension formed by mixing the pesticide active ingredient with a carrier and a dispersant and ultrafinely grinding it using a wet method. It is a solid active ingredient that is insoluble or slightly soluble in water and dispersed relatively evenly in water through ultrafine grinding with the help of certain additives, forming a highly suspended, flowable, stable liquid-solid system with fine particles. Therefore, stirring technology is a key link in the preparation of pesticide suspension concentrates, and corresponding stirring equipment is usually equipped for stirring preparation.

[0003] The stirring equipment in the prior art generally includes a frame, a stirring tank mounted on the frame, a stirring paddle built into the stirring tank, and a drive motor for driving the stirring paddle. The stirring tank is provided with a feed end and a discharge end for feeding and discharging materials. The drive motor is used for stirring. Since the drive motor drives the stirring paddle to rotate forward or reverse at the same time, i.e., unidirectional rotation, the materials rotate along the stirring direction of the stirring paddle. Some materials may not be stirred sufficiently, which affects the uniform mixing of the components in the pesticide suspension concentrate. Therefore, further improvement is needed. Utility Model Content

[0004] In order to improve the uniform mixing degree of each component in the pesticide suspension, the present application provides a pesticide suspension preparation device with bidirectional stirring.

[0005] The present application provides a bidirectional stirring pesticide suspension preparation device, which adopts the following technical solution:

[0006] A bidirectional stirring pesticide suspension preparation device comprises a frame, a stirring tank arranged on the frame, a first stirring paddle and a second stirring paddle built into the stirring tank and arranged opposite to each other, and a first driving member and a second driving member arranged on the stirring tank to respectively drive the first stirring paddle and the second stirring paddle to rotate; a feed pipe is fixedly penetrated through the top of the stirring tank, a discharge pipe is fixedly penetrated through the bottom of the stirring tank, ends of the first stirring paddle and the second stirring paddle that are away from each other are rotatably connected to the top and bottom of the stirring tank, respectively, and the first driving member and the second driving member are respectively arranged on the outer top wall and the outer bottom wall of the stirring tank; the first stirring paddle and the second stirring paddle are both detachably connected to the stirring tank.

[0007] By adopting the above technical solution, the material enters the mixing tank through the feed pipe, and the first driving member and the second driving member are respectively started to drive the first stirring paddle to rotate forward and the second stirring paddle to rotate reversely, or the first stirring paddle to rotate reversely and the second stirring paddle to rotate forward, so that the stirring directions of the first stirring paddle and the second stirring paddle are opposite, thereby stirring the material. Since the stirring directions of the first stirring paddle and the second stirring paddle are different, the material at the top of the stirring tank will be affected by gravity and stirring force after stirring, so as to collide and contact with the material stirred at the bottom, so as to stir the materials more fully, thereby improving the uniform mixing degree of the various components in the pesticide suspension concentrate. In addition, the two stirring paddles are driven by independent driving members, and the rotation speed can be adjusted separately to meet the mixing requirements of different components.

[0008] Preferably, the first stirring paddle and the second stirring paddle are both provided with protruding scrapers that abut against the inner wall of the stirring tank.

[0009] By adopting the above technical solution, a scraper is provided to scrape the material that may adhere to the inner wall of the mixing tank during the mixing process, so as to further improve the mixing effect of the material.

[0010] Preferably, it also includes a third stirring paddle rotatably connected to the stirring tank and a third driving member for driving the third stirring paddle to rotate, the length direction of the third stirring paddle is perpendicular to the axial direction of the stirring tank, and an installation space for the third stirring paddle is reserved between the first stirring paddle and the second stirring paddle.

[0011] By adopting the above technical solution, a third stirring paddle is provided, and the length direction of the third stirring paddle is perpendicular to the axial direction of the stirring tank. After starting the third driving member, it can stir the material located below to the top, and the stirring of the material is stronger and faster, thereby further improving the uniform mixing degree of the various components in the pesticide suspension.

[0012] Preferably, the inner wall of the stirring tank is provided with a guide plate, and a plurality of the guide plates are arranged at intervals along the height direction and the axial direction of the stirring tank. The guide plates are distributed in a spiral shape, and the spiral direction of the formed spiral is the same as the rotation direction of the first stirring paddle.

[0013] By adopting the above technical solution, by providing a guide plate, when the material is stirred, the material close to the guide plate and attached to the inner wall of the stirring tank can flow along the guide direction of the guide plate. Since several guide plates are spirally distributed, and the spiral shape formed is in the same direction as the first stirring paddle, it can be used to guide the flow path of the suspension, which can accelerate the possibility of the material located at the upper part flowing to the material below. As for the material located at the lower part, due to the flipping, it can just flow upstream along the guide plate, thereby further improving the stirring effect of the material, that is, further improving the uniform mixing degree of the components in the pesticide suspension.

[0014] Preferably, the length direction of the guide plate is inclined to the spiral direction of the plurality of guide plates distributed in a spiral shape.

[0015] By adopting the above technical solution, the inclination angle of the material diversion can be increased to further accelerate the stirring effect of the material.

[0016] Preferably, the guide plate is detachably connected to the stirring tank.

[0020] Preferably, a heating element for heating the material is provided at the bottom of the stirring tank.

[0021] By adopting the above technical solution, a heating element is provided to heat the pesticide suspension concentrate, thereby improving the mutual solubility of the components and further improving the uniform mixing degree of the components in the pesticide suspension concentrate.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The material enters the mixing tank through the feed pipe, and the first and second driving members are activated respectively to drive the first stirring paddle to rotate forward and the second stirring paddle to rotate reversely, or the first stirring paddle to rotate reversely and the second stirring paddle to rotate forward, so that the first stirring paddle and the second stirring paddle stir in opposite directions, thereby stirring the material in both directions. Due to the different stirring directions of the first and second stirring paddles, the material in the upper part of the stirring tank will collide and contact with the material stirred in the lower part due to gravity and stirring force after stirring, which makes the stirring between the materials more thorough, thereby improving the uniform mixing of the various components in the pesticide suspension concentrate. The two stirring paddles are driven by independent driving members, and the rotation speed can be adjusted separately to meet the mixing requirements of different components.
