Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening devices, in particular to a new type of screening device for steam coal. Background Technique
[0002] Steam coal refers to coal used as a power raw material. Generally, in a narrow sense, it refers to coal used for thermal power generation. Broadly speaking, any coal used for power generation, locomotive propulsion, boiler combustion, etc., and used to generate power belongs to steam coal for power use, simply referred to as steam coal. The process of dividing bulk materials into different particle sizes through one or several layers of sieve surfaces is called screening. A screening machine is a vibrating screening mechanical device that uses the relative movement between bulk materials and the sieve surface to make some particles pass through the sieve holes and divides materials such as sand, gravel, and crushed stones into different grades according to particle size. The screening process of a screening machine is generally continuous. After the screening raw material is fed onto the screening machine, the material smaller than the sieve hole size passes through the sieve holes and is called the undersize product; the material larger than the sieve hole size is continuously discharged from the sieve surface and is called the oversize product.
[0003] After retrieval, a screening device for a steam coal preparation plant disclosed in the Chinese utility model patent with the publication number CN218251503U, which relates to the technical field of steam coal, includes a screening box. A vibration assembly is arranged at the bottom of the screening box. A side plate is fixedly connected to the side of the screening box. A screening mesh is obliquely arranged in the inner cavity of the screening box. A discharge port is equidistantly arranged along the vertical direction on the side of the screening box. A U-shaped plate is fixedly connected to the side of the discharge port. A blocking plate is movably inserted into the U-shaped plate along the vertical direction. A vibration motor is fixedly connected to the bottom of the side of the screening box. In the utility model, a closing mechanism is movably arranged at the bottom of the screening mesh of the screening box, and a water control mechanism is arranged at the stepped pipe on the side of the screening box. After the closing mechanism closes the bottom of the screening mesh of the screening box, the water control mechanism can introduce clean water into the screening box to wash the blocked sieve holes of the screening mesh, so that the screening mesh can resume work.
[0004] However, this device often lacks the function of conveniently taking out the screened impurities. When in use, it is not convenient to take out the impurities after screening by the device, resulting in the situation that the impurities remain inside the device and are not easy to clean. Moreover, this device also lacks the function of enhancing the screening effect of powder. During the screening process on the screening mesh, there may be unscreened steam coal, resulting in the situation that the steam coal cannot be fully screened and the material is easily wasted.
