Technical Field

[0001] The invention relates to the technical field of crushing, in particular to a raw material grinding device for chemical machinery. Background Art

[0002] Chemical machinery is a general term for machines and equipment used in chemical industry production. In order to process raw materials into finished products of certain specifications in chemical production, it is often necessary to go through a series of chemical processes such as raw material pretreatment, chemical reaction, and separation and refining of reaction products. The machinery used to achieve these processes is often classified as chemical machinery, and the chemical raw materials need to be ground through grinding equipment.

[0003] Traditional chemical grinding equipment can only grind raw materials to fixed sizes or fixed types and volumes of raw materials due to its fixed equipment structure. The equipment structure is fixed and rigid, with poor flexibility. Rigidly connected equipment is prone to load blockage and internal jamming and damage. In addition, general grinding equipment only uses a single grinding method, and the particle size after grinding is still large. Particles that do not meet the requirements will cause waste of resources and affect subsequent chemical production. Summary of the invention

The material enters the top of the movable plate from the top of the machine body. Under the control of the adjusting rod, the distance between the two rollers can be freely adjusted. In this process, the limit block is adjusted up and down along the vertical groove to control the inclination angle of the movable plate. Under the action of the movable plate, the material can flow obliquely downward along the upper surface of the movable plate to the gap between the two rollers, which can ensure the crushing efficiency of the material and prevent the material from splashing. The outer surface of the inclined plate is fixedly connected to the inner surface of the machine body. The inclined plate is located at the bottom of the crushing device. After crushing, the material falls to the upper surface of the inclined plate, and small particles that meet the requirements leak out from the inclined plate for the next grinding step.

The crushing device is located at the bottom of the movable plate.

[0008] Preferably, the crushing device includes a roller, the inner surface of the roller is fixedly connected to a telescopic rod, the top of the telescopic rod is fixedly connected to a clamping plate, the roller rotates, the raw material falls from the machine body, the roller on the left rotates clockwise, and the roller on the right rotates counterclockwise.

[0014] The present invention provides a raw material grinding device for chemical machinery. It has the following beneficial effects: (I) The raw material grinding device for chemical machinery is provided with a crushing device. When the equipment is in use, the rollers rotate, and the raw materials fall from the front of the machine body. The rollers on the left rotate clockwise, and the rollers on the right rotate counterclockwise. Driven by gravity and the rollers, the materials fall and are crushed, and the convex strips participate in the extrusion operation. During the high-speed rotation of the rollers, the centrifugal force on the pressed blocks increases, and the pressed blocks are thrown out from the inside of the rollers. The clamping plates prevent the pressed blocks from falling off. The pressed blocks and the convex strips cooperate to increase the crushing frequency. When the speed of the rollers decreases, the telescopic rods contract, and the pressed blocks are pulled into the inside of the rollers. The support plates prevent the rollers from excessively deforming, thereby solving the problem that the traditional grinding devices are directly exposed, the equipment is subjected to greater impact, and the protective effect is poor.

[0015] (ii) The raw material grinding device for chemical machinery is provided with a circulation device. When the equipment is in use, the sealed cabin is fixed on the outside of the machine body, the crushing device crushes the material, the material falls, and the large pieces of material flow along the upper surface of the guide plate to the inside of the sealed cabin. Then the pulley drives the conveyor belt to rotate, and the material falling into the sealed cabin is driven from bottom to top by the fixed plate. When the material moves to the top, it is thrown out along the lower surface of the top guide plate due to inertia. The material falls into the inside of the equipment for the second time and is crushed for the second time by the crushing device until it is crushed to a specified size, thereby solving the problem of single crushing times of traditional grinding devices.

[0016] (III) The raw material grinding device for chemical machinery is provided with a refining device. When the equipment is in use, the raw materials fall into the interior of the sleeve after being repeatedly crushed by the crushing device and the circulation device. The rotating shaft drives the eccentric wheel to rotate. The raw materials are ground in the gap between the bottom plate and the eccentric wheel. The raw materials are further refined and finally the ground raw materials are discharged from the discharge pipe. In this process, the eccentricity of the eccentric wheel can be controlled by adjusting the screw to meet the grinding of particles of different sizes, thereby solving the problem of fixed grinding effect of traditional grinding devices.

[0017] (IV) The raw material grinding device for chemical machinery is provided with an adjustment device. When the equipment is in use, the ring covers the roller. Under the push and pull action of the adjustment rod, the roller slides left and right along the inner surface of the horizontal groove, thereby changing the distance between the two rollers, so as to adapt to the crushing of raw materials of different sizes, hardness and materials. Through the flexible connection, the flexibility and versatility of the equipment can be improved. At the same time, it can also effectively protect the equipment and prevent the rigid connection from causing the internal jamming and damage of the equipment, thus solving the problem that the traditional crushing equipment has a fixed structure and is easy to jam inside.

[0018] (V) The raw material grinding device for chemical machinery is provided with an adjustment device. When the equipment is in use, the material enters the top of the movable plate from the top of the machine body. Under the control of the adjustment rod, the distance between the two rollers can be freely adjusted. In this process, the limit block is adjusted up and down along the vertical groove to control the inclination angle of the movable plate. Under the action of the movable plate, the material can flow downward along the upper surface of the movable plate to the gap between the two rollers, which can ensure the crushing efficiency of the material and prevent the material from splashing. After the crushing is completed, the material falls to the upper surface of the inclined plate, and the small particles that meet the requirements leak out from the inclined plate for the next step of grinding. The larger raw materials flow along the upper surface of the inclined plate to the inside of the circulation device for secondary crushing, which solves the problem of fixed structure and poor grinding effect of traditional grinding equipment.

[0019] (VI) The raw material grinding device for chemical machinery is provided with a machine body. When the equipment is in use, the unground raw materials enter the inside of the machine body from the top. The spacing of the crushing device is controlled by the adjusting device to meet the crushing requirements of different raw materials. The flexible connection can also effectively protect the equipment, prevent the rigid fracture or deformation of the equipment, and extend the service life of the equipment. The circulation device intercepts the larger particles and performs secondary crushing. The small particle raw materials that meet the conditions leak into the inside of the refining device. In the inside of the refining device, the small particle raw materials are ground for multiple times, and the particle volume is further reduced. Through multiple crushing and graded grinding, the grinding quality can be effectively guaranteed, the size difference of the particles can be reduced, and the problem of large particle volume in traditional single grinding is solved.
