Technical Field
[0001] The utility model belongs to the technical field of screening equipment, and specifically relates to a screening component for screening chemical raw materials. Background Technique
[0002] Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. The main raw materials for inorganic chemical products are chemical minerals containing sulfur, sodium, phosphorus, potassium, calcium, etc. (see inorganic salt industry) and coal, petroleum, natural gas, as well as air, water, etc. In addition, by-products and wastes from many industrial sectors are also raw materials for inorganic chemistry.
[0003] In the production process of chemical raw materials, it is necessary to screen granular materials. Existing screening devices usually use vibration to screen them. However, in this way, the vibration effect of the screen device may be affected due to material accumulation, and material accumulation easily causes phenomena such as caking and adhesion between materials, resulting in screen blockage and affecting the screening efficiency.
[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model
[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present utility model is as follows:
[0006] A screening component for screening chemical raw materials includes a screening cylinder. One end of the screening cylinder is provided with an opening. The center position of the inner wall at the end of the screening cylinder far from the opening is fixedly connected with a central column. And a sealing cover is arranged between the inner wall of the screening cylinder and the outer wall of the central column at the opening. A screening structure is arranged between the inner and outer circumferential walls of the screening cylinder; the screening structure includes a second screen, a third screen, and a fourth screen. Installation grooves are arranged in a circumferential array between the inner and outer circumferential walls of the screening cylinder. The second screen, the third screen, and the fourth screen are fixedly installed between the inner walls of the installation grooves; the sizes of the screen holes of the second screen, the third screen, and the fourth screen are different from each other. The second screen, the third screen, and the fourth screen are all arranged in a circumferential array, and the second screen, the third screen, and the fourth screen are arranged at intervals in sequence;
[0007] A material scattering structure is arranged between the inner circumferential wall of the screening cylinder and the outer circumferential wall of the central column.
[0008] As a preferred embodiment of the present utility model, the material scattering structure is a dispersion grille. Both ends of the dispersion grille are fixedly connected with the inner circumferential wall of the screening cylinder and the outer circumferential wall of the central column respectively, and the dispersion grille is arranged in a circumferential array.
[0009] As a preferred embodiment of the present utility model, the screening structure is a first screen. Screening grooves are arranged in a circumferential array between the inner and outer circumferential walls of the screening cylinder. The first screen is fixedly installed between the inner walls of the screening grooves.
[0010] As a preferred embodiment of the present utility model, the first screen is distributed in a circumferential array, and the first screen and the dispersion grille are distributed alternately.
[0011] As a preferred embodiment of the present utility model, the screening structure further includes a sleeve, which is rotatably installed between the circumferential outer walls of the screening cylinder. A discharge port is provided in a circumferential array between the inner and outer circumferential walls of the sleeve, and the discharge port is in mutual cooperation with the three groups of screens, namely the second screen, the third screen, and the fourth screen.
[0012] The present utility model has the following beneficial effects compared with the prior art:
[0013] 1. When the device is in use, the screening cylinder is rotatably installed, and the screening cylinder is rotated by a motor to screen the materials in the screening cylinder. The cylindrical structure enables the materials in the screening cylinder to be continuously turned over, and during the turning process, the materials slide along the inner wall of the screening cylinder and collide with the first screen, so that the first screen vibrates continuously, improving the screening efficiency while avoiding the clogging of the screen holes.
[0014] 2. By providing the second screen, the third screen, and the fourth screen, the device is applicable to the screening of raw materials of different specifications. During screening, select the appropriate screen according to the requirements, and rotate the sleeve to make the discharge port coincide with the selected screen, thereby improving the convenience of classified screening of the screen and greatly expanding the application range of the device.
[0015] 3. The setting of the dispersion grille enables the raw materials tumbling in the screening cylinder to collide with the dispersion grille during the screening process, thereby continuously dispersing the materials and preventing the materials from caking and adhering to each other, which affects the screening effect.
