[0002] The screening device used in mineral powder production is usually a device used to screen and grade ore or ore powder. These devices are usually composed of a screen and a supporting structure. When the ore or ore powder passes through the screen, it is separated according to its particle size. This screening device can adjust the size of the sieve hole as needed to meet the screening requirements of ores or ore powders of different particle sizes.

[0003] There is no obstruction in the center of the screen plate in the existing device, the material flow rate in the screen barrel is fast, the material directly flows from the center of the screen plate to the second bin and directly out of the mill from the center of the mill tail. The residence time in the mill is short, there is no sufficient grinding, and the screening effect is poor. Therefore, a screening device for mineral powder production is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a screening device for mineral powder production to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a screening device for mineral powder production, comprising a base, a fixed block is fixedly connected to the upper surface of the base, a screening mechanism is arranged on one side of the fixed block, the screening mechanism comprises a screen barrel and a lining plate, a discharge port is arranged outside the screen barrel, the lining plate is fixedly connected to the inside of the screen barrel, a blind plate is arranged inside the screen barrel, a limiting ring is fixedly connected to the inside of the screen barrel, a screen plate is arranged inside the screen barrel, one end of the screen plate is clamped in the inside of the blind plate, the other end of the screen plate is sleeved on the outside of the limiting ring, sieve holes are opened on the surface of the sieve plate, the number of the sieve holes is multiple and distributed in a rectangular array, the number of the lining plate and the screen plate are both multiple and distributed in a circular array.

[0006] By setting up a screen barrel, a liner, an external gear, a motor, a blind plate, a screen plate and screen holes, the motor drives the pinion to rotate through the main shaft. Under the meshing action of the pinion and the external gear, the screen barrel starts to rotate. With the rotation of the screen barrel, the mineral powder is screened out through the screen holes. The blind plate and the liner can better control the flow rate of the material, which can prevent the material from directly rushing from the center of the screen plate to the second bin or directly out of the mill from the center of the mill tail. Instead, the material stays on the screen plate for a longer time, thereby enhancing the screening effect.

[0007] As a preferred implementation, support plates are provided in front and in the rear of the fixing block, and the support plates are fixedly connected to the upper surface of the base.

[0008] By setting up the base, it provides support and a stable foundation for the entire device.

[0009] As a preferred embodiment, the screen barrel is rotatably connected to the inside of the two support plates, and the outside of the screen barrel is fixedly connected with an external gear.

[0010] By setting the support plate, a connection point is provided for the screen bucket.

[0011] As a preferred implementation, a motor is fixedly connected to the back side of the fixing block, and an output end of the motor extends into the interior of the fixing block.

[0012] By setting up a motor, the main shaft is driven through the output end, thereby driving the screen barrel to rotate.

[0013] As a preferred implementation, the interior of the fixed block is rotatably connected to a main shaft, and the exterior of the main shaft is fixedly connected to a pinion.

[0014] A small gear is provided to mesh with the external gear so as to transmit the power of the motor to the screen barrel.

[0015] As a preferred implementation, the pinion is meshed with the external gear, and the main shaft is fixedly connected to the output end of the motor.

[0016] By setting the main shaft, it is connected to the output end of the motor through a small gear, and the power of the motor is transmitted to the screen barrel.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model is provided with a screen barrel, a lining plate, an external gear, a motor, a blind plate, a screen plate and screen holes. The motor drives the rotation of the pinion gear through the main shaft. Under the meshing action of the pinion gear and the external gear, the screen barrel starts to rotate. With the rotation of the screen barrel, the mineral powder is screened out through the screen holes. The blind plate and the lining plate better control the flow rate of the material, so that the material can be prevented from directly flowing from the center opening of the screen plate to the second bin or directly out of the mill from the center opening of the mill tail, but the material can stay on the screen plate for a longer time, thereby enhancing the screening effect.
