Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of raw material screening, in particular to a refractory raw material screening device. Background Art
[0002] Refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580 degrees. They are generally composed of a quantitative mixture of inorganic non-metallic materials of various components. The size of the refractory particles affects its use effect and durability. If the refractory particles are too large, it is easy to cause the brick structure to be too loose, the refractoriness is low, the thermal shock resistance is poor, and sintering defects are easy to occur. If the refractory particles are too small, the thermal shock resistance and mechanical strength will be affected, and it is easy to form a corundum phase at high temperature, resulting in material performance degradation. Therefore, refractory particle size screening is one of the keys to ensure product quality and performance.
[0003] However, in the prior art, most of the screens of refractory raw material screening devices are inclined, and the raw materials are screened by rolling on the surface of the screen. When the screen is tilted at a large angle, the screen may not have time to screen the raw materials before leaving the range of the screen. When the screen is tilted at a small angle, the raw materials will accumulate on the surface of the screen, which greatly affects the screening rate. Utility Model Content
[0004] The purpose of the utility model is to solve the problems existing in the prior art.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a refractory raw material screening device, comprising: a screening box, a filling port is installed on the top surface of the screening box, a discharge port is installed on the bottom surface of the screening box, a plurality of supporting legs are fixedly installed on the bottom surface of the screening box, a controller is fixedly installed on one side surface of the screening box, a discharge port is installed on the other side surface of the screening box, vibration components are provided on both side surfaces of the screening box, and a discharge component is provided on the top surface of the screening box.
[0006] As a preferred embodiment, the two vibration assemblies include four first through grooves, which are symmetrically opened on the two side surfaces of the screening box in a group of two each, vertical rods are fixedly installed on the upper and lower end inner wall surfaces of the four first through grooves, sliding plates are slidably connected to the surfaces of the four vertical rods, screens are fixedly installed between opposite sides of the four sliding plates, long plates are fixedly installed between the four sliding plates in a group of two each, and springs are fixedly installed between the top inner wall surfaces of the four first through grooves and the four sliding plates.
[0007] As a preferred embodiment, motor frames are fixedly mounted on both side surfaces of the screening box, rotating motors are fixedly mounted on one side surface of the two motor frames, and cams are fixedly mounted on output ends of the two rotating motors.
[0008] As a preferred embodiment, the discharge assembly includes a second through groove, which is opened on the top surface of the screening box, a long rod is fixedly installed between the inner wall surfaces at both ends of the second through groove, a sliding block is slidably connected to the surface of the long rod, a connecting frame is fixedly installed on the bottom surface of the sliding block, and a scraper plate is fixedly installed on the end port of the connecting frame away from the sliding block.
[0009] As a preferred embodiment, the interior of the slider is connected to a rotating rod via a bearing, a U-shaped plate is fixedly installed on the surface of the slider, a forward and reverse motor is fixedly installed on one side surface of the U-shaped plate, and the output end of the forward and reverse motor is fixedly connected to one end surface of the rotating rod.
[0010] As a preferred embodiment, a gear is fixedly mounted on the other end of the rotating rod, a rack is fixedly mounted on the top surface of the screening box, and the rack and the gear are meshed with each other.
[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] 1. The utility model provides a vibration component. When it is necessary to screen the refractory material, firstly, the two rotating motors are operated by the controller. The operation of the two rotating motors drives the two cams to rotate. The two cams rotate, so that the two long plates move upward. The upward movement of the two long plates drives multiple sliding plates to move upward on the surfaces of the multiple vertical rods. The multiple sliding plates move upward on the surfaces of the multiple vertical rods to squeeze multiple springs, so that the multiple springs are compressed. At the same time, the multiple sliding plates also drive the screen to move upward on the surfaces of the multiple vertical rods. When the two cams are separated from the long plates, the multiple sliding plates are reset by utilizing the rebound force of the multiple springs, so that the screen can be repeatedly moved up and down quickly. Due to the effect of inertia, the raw materials on the surface of the screen will also move up and down, so as to achieve the purpose of vibration, avoid larger particles of raw materials staying on the surface of the screen to block the screening, and through the cooperation of the above structure, the raw materials on the surface of the screen can achieve the purpose of vibration, which can not only speed up the screening rate, but also avoid larger particles of raw materials staying at the bottom to block the screen, thereby greatly improving the screening rate of the device.
[0013] 2. The utility model provides a discharging assembly. When the raw materials on the surface of the screen need to be discharged from the inside of the screening box after screening, the forward and reverse motors are first operated through the controller. The operation of the forward and reverse motors drives the rotating rod to rotate. The rotation of the rotating rod drives the gear to rotate. The rotation of the gear and the rack engage with each other, so that the slider slides on the surface of the long rod. The sliding of the slider on the surface of the long rod drives the connecting frame to move. The movement of the connecting frame drives the scraper plate to move. The scraper plate moves to discharge the raw materials remaining on the surface of the screen from the discharging port. When the scraper plate completes the scraping work and resets, the forward and reverse motors can be stopped to complete the scraping of the raw materials on the surface of the screen. Through the cooperation of the above-mentioned structure, it is avoided that the raw materials with larger particles after screening stay on the surface of the screen to block the screen, thereby affecting the next screening, thereby improving the practicality of the device.
