Description
Technical Field
[0001] The present application relates to the technical field of machine-made sand and mud powder screening, and in particular to a machine-made sand and mud powder screening and cleaning device. Background Art
[0002] Artificial sand is artificial sand with a particle size less than 4.75mm, which is processed by the artificial sand production system. Due to the advantages of uniform particle size, good particle shape, reasonable grading, high degree of production automation and low cost, it is now more and more widely used in industries such as commercial concrete, dry-mixed mortar, and asphalt concrete. At the same time, screening technology is one of the important technologies in the production of artificial sand.
[0003] In the process of screening artificial sand, due to the small particle size of artificial sand, the pores of the screen will also be set relatively small, and the coarse mud powder may block the pores on the screen, making it difficult for the mud powder to pass through the sieve holes, affecting the screening effect of the device. At this time, the screen needs to be cleaned manually. Since the screen is located inside the device, manual cleaning is very inconvenient. Therefore, an improvement is now made to a machine-made sand and mud powder screening and cleaning device. Utility Model Content

[0006] By adopting the above technical solution, the mixture of machine-made sand and mud powder is vibrated and screened by a vibrating screen machine, and the machine-made sand is screened and filtered by setting a screen. The mud powder falls to the bottom through the screen. After long-term use, the mud powder may block the pores on the screen, making it difficult for the mud powder to pass through the sieve holes, affecting the screening efficiency of the device. At this time, the cleaning unit is driven by the rotation of the set threaded rod to move back and forth along the sliding rod to clean the blocked screen. The device can automatically clean the blocked screen without manual cleaning, which greatly reduces the difficulty of cleaning.
[0007] As a preferred technical solution of the present application, a motor is fixedly installed at one end of the vibrating screen machine, one end of the threaded rod is fixedly connected to the output end of the motor, and the cleaning unit slides on the outer surface of the sliding rod.
[0008] By adopting the above technical solution, the threaded rod is driven to rotate by the motor, so that the cleaning unit moves back and forth along the sliding rod to clean the blocked screen.
[0009] As a preferred technical solution of the present application, the cleaning unit includes a cleaning block, a rectangular groove is opened inside the cleaning block, a spring is fixedly connected inside the rectangular groove, a moving block is fixedly connected to the other end of the spring, a cleaning plate is fixedly installed at the lower end of the moving block, and a dense cleaning brush is provided on the outer surface of the cleaning plate.
[0010] By adopting the above technical solution, when the cleaning unit cleans the screen, the elastic force of the spring is used to adjust the position of the moving block, thereby adjusting the position of the cleaning plate, so that the cleaning brush on the cleaning plate fits against the uneven surface of the screen to clean it, thereby enhancing the cleaning ability of the cleaning unit.
[0011] As a preferred technical solution of the present application, a feed hopper is fixedly installed on the upper surface of the vibrating screen machine, and the inner wall of the feed hopper is smooth.
[0012] By adopting the above technical solution, machine-made sand enters the interior of the vibrating screen through the feed hopper. The smooth inner wall of the feed hopper can reduce friction and facilitate material discharge, avoiding material accumulation inside the feed hopper.
[0013] As a preferred technical solution of the present application, a machine-made sand discharge trough is fixedly installed at the discharge end of the conveying channel above the screen inside the vibrating screen machine, and a mud powder discharge trough is fixedly installed at the discharge end of the conveying channel below the screen inside the vibrating screen machine.
[0014] By adopting the above technical solution, the machine-made sand is transported out through the machine-made sand discharging trough, and the mud powder is transported out through the mud powder discharging trough.
[0015] As a preferred technical solution of the present application, the discharge ports of the machine-made sand discharge trough and the mud powder discharge trough are arranged in opposite directions.
[0016] By adopting the above technical solution, the machine-made sand and mud powder are discharged separately into the collecting containers on both sides without hindering each other.
[0017] Beneficial effects of this application:
[0018] In the utility model, a vibrating screen is provided to vibrate and screen the mixture of machine-made sand and mud powder, and the machine-made sand is screened and filtered through a screen, and the mud powder falls below through the screen. After long-term use, the mud powder may clog the pores on the screen, making it difficult for the mud powder to pass through the screen holes, affecting the screening efficiency of the device. At this time, the threaded rod is driven to rotate by a motor, so that the cleaning unit moves back and forth along the sliding rod to clean the clogged screen. The device can automatically clean the clogged screen without manual cleaning, which greatly reduces the difficulty of cleaning.
