Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide production technology, specifically to a pesticide sand milling system. Background Technology
[0002] In the field of pesticide production, traditional pesticide grinding methods mainly include ball milling, sand milling, and air jet milling. Ball milling involves placing pesticide raw materials and grinding media together in a sealed grinding jar of a ball mill. The high-speed rotation of the jar utilizes the grinding media to impact, collide, and grind the raw materials, achieving particle refinement. Sand milling relies on a sand mill, where a high-speed rotating dispersing disc drives the grinding media within a grinding chamber filled with a mixture of raw materials and dispersant, subjecting the raw materials to intense shearing, friction, and impact to refine the particles. Air jet milling uses a high-speed airflow (usually compressed air or superheated steam) to accelerate the pesticide raw materials, causing intense collisions, friction, and shearing between particles and between particles and the inner wall of the equipment, thereby achieving particle refinement.
[0003] However, these traditional grinding methods have many problems in application. Ball mills have low grinding efficiency, and due to the randomness of the grinding media's movement, it is difficult to precisely control the force applied to the raw material, easily resulting in uneven particle grinding and potentially introducing impurities during the grinding process. Sand mills, when processing high-viscosity raw materials, may experience problems such as excessive load on the dispersion disc and difficulty in heat dissipation, affecting grinding efficiency and equipment lifespan. Colloid mills are not effective at grinding raw materials with high hardness or viscosity, making it difficult to achieve the desired particle size. Air jet mills have high equipment investment, high energy consumption, and high operating and maintenance costs. Utility Model Content
[0004] To address the technical problems of uneven grinding and excessively high material temperature during grinding in traditional grinding methods, this utility model provides a pesticide sand milling system.
[0005] The technical solution provided by this utility model is as follows:
[0006] A pesticide sand milling system includes a pulverizer, a pulverizing motor fixedly installed on the top of the pulverizer, and a pulverizer feeding port. The drive shaft of the pulverizing motor extends into the pulverizing chamber of the pulverizer, and a rotating pulverizing part is fixedly installed on the drive shaft. The rotating pulverizing part is provided with several pulverizing blades. A chamber wall filter screen is provided between the pulverizing chamber and the receiving chamber below it, and a material pulverizing space is formed between the chamber wall filter screen and the rotating pulverizing part.
[0007] The discharge port at the bottom of the receiving hopper is connected to the feed port of the grinder. The feed port leads directly to the horizontal grinding barrel. The horizontal grinding barrel is covered with an outer shell. A cooling jacket is formed between the horizontal grinding barrel and the outer shell to allow cooling water to circulate. The outer shell has an outlet and an inlet. The outlet and inlet are connected to a cooling water circulation device through cooling water pipes. A rotating shaft is horizontally installed inside the horizontal grinding barrel. Several grinding discs are installed on the rotating shaft. One end of the rotating shaft extends out of the outer shell and is rotatably connected to the grinding motor fixed on the outer shell.
[0008] Furthermore, the crusher has one or two feed inlets, and a suitable cover is hinged to the feed inlet.
[0009] Furthermore, the lower part of the rotary crushing section is inverted conical in shape, the filter screen on the bin wall is a funnel-shaped filter screen adapted to the lower part of the rotary crushing section, and several crushing blades are evenly arranged in the lower part of the rotary crushing section, with the crushing blades having a conical or plate-like structure.
[0010] Furthermore, the bottom of the receiving hopper is funnel-shaped.
[0011] Furthermore, the discharge port at the bottom of the receiving hopper is connected to the inlet at the top of the grinder via a pipe, and a screw pump is installed on the pipe.
[0012] Furthermore, a coil is coiled inside the cooling jacket, with both ends of the coil connected to the cooling water pipe through an outlet and an inlet, respectively.
[0013] Furthermore, there are several radially arranged serrated protrusions on one side surface of the grinding disc, and multiple grinding through holes are opened on the grinding disc between the serrated protrusions, with the edges of the grinding through holes being serrated.
[0014] The serrated protrusions and grinding through holes further enhance the grinding effect. Multiple grinding discs, with different grinding structures, grind the material from different angles, increasing the contact area between the material and the grinding components and the grinding path, making the material more evenly stressed during the grinding process.
[0015] Furthermore, an outlet is opened at a diagonal position opposite the feed inlet on the top of the grinder.
[0016] The beneficial effects of this utility model are as follows:
[0017] (1) High efficiency and precision in crushing: The rotary crushing part is equipped with several crushing blades, which rotate at high speed under the drive of the crushing motor, which can crush the material to a suitable particle size more quickly and achieve good crushing effect;
[0018] (2) It has a preliminary screening function: a filter screen is set between the crushing chamber and the receiving chamber. After the material is crushed by the crushing head, it can be preliminarily screened through the filter screen. Larger particles are intercepted and crushed further. Materials that meet the requirements enter the receiving chamber at the bottom, which avoids the entry of insufficiently crushed materials into the subsequent process, and ensures the relative consistency of the particle size of the materials entering the grinding stage, which helps to improve the uniformity and efficiency of subsequent grinding.
[0019] (3) Uniform grinding and effective control of grinding temperature: Multiple grinding discs are set on the rotating shaft inside the horizontal grinding barrel, so that the material is subjected to more uniform force during the grinding process. The horizontal grinding barrel is covered with an outer shell with a cooling jacket and connected to a cooling water circulation device. During the grinding process, the cooling water circulates and carries away the heat generated by grinding, effectively avoiding the performance changes and component decomposition of the material due to excessive temperature during fine grinding, ensuring the chemical stability and effectiveness of pesticides, extending the service life of the equipment, and reducing the safety hazards caused by excessive temperature.
[0020] (4) The overall process is coherent and improves production efficiency: From raw material crushing, preliminary screening, and transportation to fine grinding and cooling treatment, each link is closely connected to form an efficient and coherent production process, which reduces manual intervention and material turnover time, improves the overall production efficiency of pesticide sand milling, and reduces production costs.

Cooling water enters the cooling jacket 7 through the inlet, then flows out through the outlet and re-enters the cooling water circulation device 10, thereby cooling the material inside the horizontal grinding barrel and effectively preventing excessive temperature during fine grinding. After grinding and cooling, the pesticide raw materials are discharged from the grinder outlet and can be used for subsequent processes.
