Description

Technical Field

[0001] The present application relates to the technical field of pesticide preparation production, and specifically discloses a device for diluting a pesticide preparation raw material. Background Art

[0002] The original pesticides generally cannot be used directly and must be processed and prepared into various types of preparations before they can be used. Commercial pesticides are sold to users in a certain dosage form.

[0003] In the production process of pesticide formulations, the dilution of the original drug is one of the essential steps. The basic method of diluting the original drug is to prepare a certain proportion of water and the original drug, and then stir and mix them to form a diluted solution. This process is usually carried out in a blender.

[0004] A common mixer is equipped with a feed pipe on the top for the raw medicine and water to enter the mixing chamber for mixing and stirring. The amount of raw medicine and water entering the mixing chamber is usually pre-set and controlled by a metering pump or a metering valve. However, after entering the feed pipe under the control of the raw medicine metering pump or the metering valve, part of the raw medicine adheres to the inner wall of the pipe, resulting in the amount of raw medicine entering the mixing chamber being lower than the set value, thereby affecting the concentration of the diluted liquid and causing part of the raw medicine to be wasted. Therefore, in view of this, the inventor provides a raw medicine dilution device for pesticide preparation production to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that when a traditional mixer dilutes the original medicine, part of the original medicine adheres to the inner wall of the feed pipe, thereby affecting the concentration of the diluted medicine solution.

[0006] To achieve the above-mentioned objectives, the basic solution of the present invention provides a pesticide preparation production technical dilution device, comprising a frame, a stirring chamber provided on the frame, and a stirring assembly for stirring the technical and water in the stirring chamber, wherein a feed main is provided on the top of the stirring chamber, a conversion pipe is connected horizontally to the side wall of the feed main, and a feed branch pipe located above the conversion pipe is vertically connected to the conversion pipe;

[0007] The frame is also provided with a reciprocating drive member, and a piston driven by the reciprocating drive member and capable of extending into the feed pipe is slidingly and sealedly connected in the conversion pipe. A discharge pipe is provided at the bottom of the mixing bin, and a control valve is provided on the discharge pipe.

[0008] The principles and effects of this basic solution are:

[0009] Compared with the existing technology, the utility model sets a feed main pipe, a conversion pipe and a feed branch pipe, uses the feed main pipe to supply water, and the feed branch pipe to supply the raw medicine, and uses a reciprocating drive to drive the piston to move, pushing the raw medicine in the conversion pipe into the feed main pipe. At the same time, the water flow when the feed main pipe is used for water supply is used to flush the raw medicine adhered to the piston, so that all the raw medicine enters the mixing chamber under the action of the water flow, thereby solving the problem that when the traditional mixer dilutes the raw medicine, part of the raw medicine adheres to the inner wall of the feed pipe, affecting the concentration of the diluted medicine liquid.

[0010] Furthermore, a sealing sleeve is provided at one end of the piston away from the feed pipe and is slidably and sealingly connected to the inner wall of the conversion conduit. The sealing sleeve can prevent the raw medicine from adhering to the output shaft of the reciprocating drive member, thereby avoiding waste of the raw medicine.

[0011] Furthermore, the cavity inside the conversion pipe has a square cross-section, and a block is slidably and sealingly connected to the top of the conversion pipe's sidewall, which blocks the conversion pipe. The block is located between the main feed pipe and the feed branch pipe. The block not only prevents water from entering the conversion pipe and the feed branch pipe, but also ensures a quantitative supply of the technical drug.

[0012] Furthermore, the side wall of the conversion pipe is provided with an adjustment tube located between the main feed pipe and the branch feed pipe. A slider is slidably connected to the adjustment tube, and one end of the block extends into the adjustment tube and is slidably connected to the slider. The adjustment tube and the slider can protect the block.

[0013] Furthermore, a spring in a compressed state is provided between the slider and the top of the adjustment tube. The spring can drive the slider to move, so that the blocker comes into close contact with the cavity inside the conversion tube. When the spring is located between the slider and the top of the adjustment tube, it must be in a compressed state to meet the requirements of use.

[0014] Furthermore, a spring in a stretched state is provided between the slider and the bottom of the adjustment tube. The spring can drive the slider to move, so that the blocker comes into close contact with the cavity inside the conversion tube. When the spring is located between the slider and the bottom of the adjustment tube, it must be in a stretched state to meet the requirements of use.

[0015] Furthermore, the opposite side of the block and the piston is provided with an inclined surface, which not only facilitates pushing the block but also allows the water flow to better impact the surface of the piston. BRIEF DESCRIPTION OF THE DRAWINGS

The cavity within the conversion pipe 8 is square, and the block 14 and the piston are both provided with inclined surfaces on the side opposite to each other. A spring 11 is provided between the slider 13 and the adjusting tube 10.

[0024] In this embodiment, the feed main pipe 3 is used to supply water and the feed branch pipe 4 is used to supply the raw medicine. The raw medicine enters the conversion pipe 8, and the reciprocating drive part 7 drives the piston to move back and forth in the conversion pipe 8 to push the raw medicine in the conversion pipe 8 into the feed main pipe 3.

An adjustment pipe is installed at the top of the side wall of the conversion pipe, located between the feed main pipe and the feed branch pipe. A slider is slidingly connected within the adjustment pipe, and the slider is connected to a block. One end of the block extends into the conversion pipe and seals the cavity inside the conversion pipe. Correspondingly, the block is slidingly and sealingly connected to the side of the conversion pipe. The cavity inside the conversion pipe is square, and the opposite sides of the block and piston are each provided with an inclined surface. A spring is installed between the slider and the adjustment pipe. When the spring is located between the slider and the top of the adjustment pipe, the spring is in a compressed state. When the spring is located between the slider and the bottom of the adjustment pipe, the spring is in a stretched state and is fixed to the slider and the adjustment pipe, respectively.

[0028] In this embodiment, the feed main pipe is used to supply water and the feed branch pipe is used to supply the raw medicine. The raw medicine enters the conversion pipe, and the reciprocating drive drives the piston to move back and forth in the conversion pipe to push the raw medicine in the conversion pipe into the feed main pipe. At the same time, the water flow when the feed main pipe is used to supply water is used to flush the raw medicine adhering to the piston, so that all the raw medicine enters the mixing bin under the action of the water flow, thereby solving the problem that when the traditional mixer dilutes the raw medicine, part of the raw medicine adheres to the inner wall of the feed pipe, affecting the concentration of the diluted medicine liquid. The raw medicine enters the feed bin together with the water from the feed main pipe, and the stirring motor drives the stirring roller to stir and mix the raw medicine and water.
