Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of limestone processing equipment, specifically to a screening device for limestone discharge. Background Technology
[0002] Limestone is an important raw material widely used in many fields such as construction and chemical industry. During its processing, the particle size has a significant impact on subsequent production stages, therefore, screening at the discharge stage is essential.
[0003] Typically, screening devices are installed at the bottom of the hopper to screen limestone to ensure that the particle size meets the corresponding production requirements. However, traditional limestone discharge screening devices have some problems. During the screening process, limestone easily clogs the screen, and cleaning the screen is very inconvenient due to the lack of effective cleaning measures. This clogging not only affects the screening efficiency, causing the screening work to be unstable and unsustainable, but may also reduce the screening accuracy, thus negatively impacting the entire production process and reducing production efficiency. Therefore, there is a need for a limestone discharge screening device that can effectively solve the screen clogging problem and is easy to clean. Utility Model Content

[0027] Combined with appendix Figure 1 To be continued Figure 7 A limestone discharge screening device includes a housing 1, a screen 2 inside the housing 1, an oscillating motor 3 fixedly mounted at the bottom center of the screen 2, a slag discharge port 4 on the left side of the housing 1 corresponding to the screen 2, a cleaning roller assembly for cleaning the screen 2 sliding between the front and rear side walls of the housing 1 and above the screen 2, an electric push rod 5 for driving the cleaning roller assembly to move horizontally fixedly mounted on the outer side wall of the housing 1, an electric push rod 6 fixedly mounted on the inner wall of the housing 1 and below the screen 2, an air blowing pipe 7 fixedly mounted on the piston end of the electric push rod 6, the air blowing pipe 7 being connected to an external high-pressure air pump via a hose, and a plurality of air jets 8 facing the mesh of the screen 2 being mounted on the upper end of the air blowing pipe 7.
[0028] The sweeping roller assembly includes a U-shaped frame 9 slidably disposed between the inner walls of the housing 1, a sweeping roller 10 rotatably disposed inside the U-shaped frame 9, a brush 11 fixedly disposed on the surface of the sweeping roller 10, a motor 12 for driving the sweeping roller 10 to rotate fixedly disposed on the side of the U-shaped frame 9, and the piston end of the electric push rod 5 is fixedly connected to the U-shaped frame 9.
[0029] The right side wall of the housing 1 is provided with a receiving chamber 13 for accommodating the cleaning roller assembly, and the right side of the housing 1 is provided with a second receiving chamber 14 for accommodating the air blowing pipe 7. The bottom of the housing 1 is funnel-shaped and the outer side wall is fixed with a second oscillating motor 15 for preventing outlet blockage.
[0030] The working principle of this limestone screening device is as follows: The device primarily uses a vibrating motor 3 to drive the screen 2 to vibrate, achieving preliminary screening of the limestone. Simultaneously, a cleaning roller assembly and an air blowing pipe 7 prevent clogging of the screen 2. Driven by an electric push rod 5, the cleaning roller assembly moves horizontally above the screen 2, and the brush 11 on the cleaning roller 10 rotates to clean the surface of the screen 2. The air blowing pipe 7 moves at the bottom of the screen 2 under the push of an electric push rod 6, and high-pressure gas is blown out through the jet nozzle 8 to remove blockages from the mesh of the screen 2, ensuring smooth screening. The funnel-shaped bottom of the housing 1 and the vibrating motor 15 on the outer wall prevent limestone from clogging at the outlet.
[0031] The working process of the limestone discharge screening device of this utility model is as follows:
[0032] 1. Start-up preparation: Start the vibrating motor 3 and vibrating motor 15 to make the screen 2 and the bottom of the box 1 vibrate. At the same time, start the external high-pressure air pump connected to the air blowing pipe 7.
[0033] 2. Screening process: Limestone falls from the top of the box 1 and lands on the screen 2. Under the vibration of the vibrating motor 3, limestone that meets the particle size requirements falls through the screen 2, while larger limestone particles that do not meet the particle size requirements remain on the screen.
[0034] 3. Screen cleaning: After the screen 2 has been working for a period of time, start the electric push rod 5. The electric push rod 5 pushes the U-shaped frame 9 of the cleaning roller assembly, so that the U-shaped frame 9 slides between the front and rear side walls inside the box 1. At the same time, start the motor 12 to drive the cleaning roller 10 to rotate. The brush 11 on the surface of the cleaning roller 10 cleans the surface of the screen 2. By controlling the rotation direction and movement direction of the cleaning roller, large particles of limestone or impurities can be pushed towards the slag discharge port 4.
[0035] 4. Start the electric push rod 6. The electric push rod 6 pushes the air blowing pipe 7 to move at the bottom of the screen. The air jet 8 at the upper end of the air blowing pipe 7 faces the screen 2. High-pressure gas is sprayed out from the air jet 8 to blow and clean the mesh of the screen 2, blowing out the limestone particles stuck in the mesh.
[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
