Abstract
Description
Technical Field
[0001] This utility model relates to the field of salt screening, and more particularly to a salt particle screening device. Background Technology
[0002] A salt granule screening device is a specialized piece of equipment used to classify and screen salt according to particle size. It is mainly used in food processing, chemical production and other fields to ensure the uniformity and quality of salt products and effectively improve processing efficiency.
[0003] Existing salt particle screening devices lack an automatic screen cleaning function, which makes it easy for salt particles to get stuck in the screen holes and cause blockage, seriously affecting screening efficiency. At the same time, the equipment relies entirely on a vibrating motor for screening operations. Long-term high-frequency vibration can easily cause loosening, displacement, or even breakage of the connection points of various components, which not only affects screening accuracy but also shortens the service life of the equipment.
[0004] Therefore, given that the existing salt particle screening devices lack a screen cleaning function and are prone to clogging, and that relying on a vibrating motor for screening can easily lead to loosening of the equipment connection points with long-term use, there is an urgent need to design a new type of salt particle screening device. Utility Model Content
[0005] To overcome the problems of existing salt granule screening devices lacking a screen cleaning function, which easily leads to clogging, and relying on vibrating motors for screening, which can easily cause the equipment connection points to loosen with long-term use.
[0006] The technical solution of this utility model is as follows: a salt granule screening device, including a screening box; it also includes electric guide rails, a mounting frame, a first drive motor, a lead screw, a movable seat, an electric push rod, an adsorption plate, a gear ring, brush bristles, a mounting plate, a second drive motor, a drive gear, and an air pipe connector. A screen is provided on the inner surface of the screening box, and a discharge pipe is installed on the bottom surface of the screening box. Electric guide rails are installed on both the left and right sides of the top surface of the screening box. The upper surfaces of the two electric guide rails are connected to the mounting frame via electric sliders. The first drive motor is installed on the right side surface of the mounting frame, and the output end of the first drive motor passes through the mounting frame. One end of a lead screw is installed on the right side wall of the mounting frame, and the other end of the lead screw is rotatably connected to the left side of the inner surface of the mounting frame. A movable seat is threaded through the outer surface of the lead screw, and an electric push rod is installed on the bottom surface of the movable seat. An adsorption plate is connected to the telescopic end of the electric push rod. A toothed ring is rotatably connected to the edge of the upper surface of the adsorption plate. The bottom surface of the toothed ring is provided with bristles. An installation plate is installed at the front position of the upper surface of the adsorption plate. A second drive motor is installed at the top of the inner surface of the installation plate. The output end of the second drive motor is connected to a drive gear, which meshes with the toothed ring. An air pipe connector is installed on the right side of the upper surface of the adsorption plate.
[0007] Preferably, by setting a second drive motor, its output end can drive the drive gear to rotate during operation. When the drive gear rotates, it can drive the meshing gear ring to rotate synchronously, activating the electric push rod, so that the bristles can come into contact with the upper surface of the screen, thereby cleaning the surface of the screen and preventing the mesh from clogging. Furthermore, by setting an air pipe connector, it can be connected to an external suction pump to suck up and collect the cleaned impurities. When the first drive motor is running, it can drive the lead screw to rotate. When the lead screw rotates, it can drive the moving seat with its thread to move left and right. With the cooperation of the electric guide rail, the adsorption plate can cover the upper surface of the screen in all directions, thereby improving the cleaning quality and agitating the salt to be screened. This solves the problem that existing salt particle screening devices lack a screen cleaning function and are prone to clogging, and that relying on a vibrating motor for screening can easily lead to loosening of the equipment connection points after long-term use.
[0008] Preferably, sliding strips are provided on both the left and right surfaces of the screen, and the screen is slidably connected to the screening box through the sliding strips.
[0009] Preferably, a pull rod is installed on the front surface of the screen, and a protective sleeve is fitted on the outer surface of the pull rod.
[0010] Preferably, a baffle is rotatably connected to the bottom surface of the discharge pipe, and a driven gear is installed on the right side of the bottom surface of the baffle.
[0011] Preferably, a fixing plate is installed on the right side surface of the discharge pipe, and a third drive motor is provided on the bottom surface of the fixing plate. The output end of the third drive motor is connected to a drive gear, and the drive gear meshes with the driven gear.
[0012] Preferably, a fixed frame is installed on the lower part of the outer surface of the screening box, and a support leg is provided at the bottom corner of the fixed frame, and a base plate is installed on the bottom surface of the support leg.
[0013] Preferably, casters are provided at the corners of the bottom surface of the base plate, and the casters are fixed to the base plate with screws.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting a second drive motor, its output end can drive the drive gear to rotate. The meshing action of the drive gear and the gear ring can drive the brush bristles to rotate, activating the electric push rod, so that the brush bristles can fit against the screen, thereby cleaning the screen and preventing the mesh from clogging. The external suction pump can be connected to the air pipe connector to suck up and collect the cleaned impurities. When the first drive motor is running, it can drive the lead screw to rotate. The threaded engagement between the moving seat and the lead screw can move left and right. With the cooperation of the electric guide rail, the adsorption plate can fully cover the upper surface of the screen, thereby improving the cleaning quality. At the same time, it can agitate the salt to be screened, thus solving the problem that existing salt particle screening devices lack screen cleaning function and are prone to clogging. In addition, relying on the vibrating motor for screening can easily lead to the loosening of equipment connection points after long-term use. Attached Figure Description
