Description

Technical Field

[0001] The utility model relates to the technical field of bead mills, in particular to a horizontal closed bead mill for producing insecticides. Background Art

[0002] The working principle of the bead mill is mainly to use the motor to drive the grinding beads to rotate at high speed, and use the friction and shear force of the grinding beads to finely grind and mix the materials. This process involves putting the materials into the grinding beads, and through the strong impact, friction and shear force generated by the high-speed rotation of the grinding beads, the materials are finely ground and mixed.

[0003] In the prior art, a horizontal bead mill is an agitator bead mill with a horizontal grinding container, which is used for dispersion and fine wet grinding in a completely closed system. In the initial stage of grinding, the raw material has a large particle size and the grinding efficiency is relatively high. However, after the initial stage, due to the dispersion of the raw material and the grinding beads, some raw materials that have escaped the net are not easy to be ground into the required particle size by the grinding beads. In order to ensure the overall grinding quality, the grinding time is greatly prolonged, which affects the overall grinding efficiency. Summary of the invention

[0004] The technical problem to be solved by the utility model is: in order to overcome the shortcomings in the prior art that raw materials and grinding beads are relatively dispersed, some raw materials that slip through the net are not easily ground into particle sizes that meet the requirements by the grinding beads, and in order to ensure the overall grinding quality, the grinding time is greatly prolonged, which affects the overall grinding efficiency. The utility model provides a horizontal closed bead mill for the production of insecticides.

[0005] The utility model solves the technical problem by adopting the following technical scheme: a horizontal closed bead mill for producing insecticides, comprising a base and a grinding cylinder, wherein the grinding cylinder is horizontally arranged on the base and has an adjustable inclination angle, a barrel cover is arranged at the opening of the grinding cylinder, a rotating shaft penetrating into the grinding cylinder is rotatably arranged on the barrel cover, a motor connected to the rotating shaft for transmission is arranged on the barrel cover, a turntable is rotatably arranged in the grinding cylinder, a screen is arranged on the turntable, a polygonal hole connected to the rotating shaft is arranged at the center of the turntable, a feed pipe and a discharge pipe are arranged on the grinding cylinder, the feed pipe is arranged on a side of the turntable away from the barrel cover, the discharge pipe is arranged on a side of the turntable close to the barrel cover, and a plurality of grinding beads are arranged between the turntable and the bottom of the grinding cylinder.

[0006] The pesticide raw material is injected into the grinding cylinder through the feed pipe, and the motor drives the shaft to rotate, which drives the turntable to rotate. The turntable stirs the raw material and drives the grinding beads to roll, thereby wet grinding the raw material in the grinding cylinder. After the raw material has been ground to a certain extent, the grinding cylinder is slightly tilted by adjusting the inclination angle of the grinding cylinder, so that the grinding beads in the grinding barrel are close to the turntable, and the raw material that meets the specifications after grinding flows to the other side of the turntable through the screen on the turntable. The remaining raw material is ground more intensified by the gathered grinding beads, thereby improving the grinding efficiency, and finally the ground raw material is discharged from the discharge pipe.

[0007] Furthermore, in order to facilitate the adjustment of the angle of the grinding cylinder, two first support rods are arranged opposite to each other on both sides of the bottom of the grinding cylinder, the lower end of the first support rod is fixedly connected to the base, the upper end of the first support rod is hinged to the side wall of the grinding cylinder near the bottom, and second support rods are arranged opposite to each other on both sides of the grinding cylinder body, the lower end of the second support rod is hinged to the base, and the upper end is slidably connected to the grinding cylinder body, a connecting rod is arranged between the two second support rods, a hydraulic cylinder is arranged on the base, the cylinder body of the hydraulic cylinder is hinged to the base, and the output end of the hydraulic cylinder is hinged to the connecting rod. The second support rod is driven to rotate along the hinge point by the extension and contraction of the output end of the hydraulic cylinder, so as to control the grinding cylinder to switch between the horizontal position and the inclined position.

[0008] Furthermore, in order to reduce the friction of the second support rod on the outer wall of the grinding cylinder when the second support rod rotates, two reinforcing slides corresponding to the position of the second support rod are provided on the grinding cylinder body, and a slide groove is provided on the reinforcing slide, and a pulley cooperating with the slide groove is provided at the upper end of the second support rod.

[0009] Furthermore, in order to prevent a dead angle between the grinding beads and the turntable, a limiting ring is provided on the side of the turntable away from the barrel cover, and the side of the limiting ring away from the turntable is a curved surface that fits the grinding beads.

[0010] Furthermore, a plurality of guide limit strips are provided on the inner side of the grinding cylinder along the circumferential direction, a plurality of limit grooves cooperating with the guide limit strips are provided on the outer wall surface of the turntable, and the spacing between the guide limit strips and the limit ring is equal to the thickness of the turntable.

[0011] When the turntable is installed, it slides into the grinding barrel through the corresponding position of the limit groove and the guide limit strip. When the turntable is against the limit ring, the turntable is rotated to misalign the limit groove and the guide limit strip to prevent the turntable from sliding out along the guide limit strip. The turntable is arranged between the guide limit strip and the limit ring and can rotate axially. When the barrel cover is closed, the rotating shaft is inserted into the polygonal hole to press against the turntable, so that the turntable will not collide with the guide limit strip during the grinding process.

[0012] The beneficial effect of the utility model is that the utility model provides a horizontal closed bead mill for insecticide production, which adopts an adjustable grinding cylinder inclination angle. After the raw materials are ground to a certain extent, the grinding cylinder is slightly tilted, so that the grinding beads in the grinding barrel are close to the turntable, and the remaining raw materials are ground more intensified, thereby improving the grinding efficiency.
