Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to an efficient quartz sand screening device. Background Technique

[0002] Quartz sand is quartz particles formed by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. The color of quartz sand is milky white or colorless and translucent. Its Mohs hardness is 7. Quartz sand is an important industrial mineral raw material, not a chemical dangerous good, and is widely used in industries such as glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, and filter materials.

[0003] The existing screen frame for each layer is a horizontal square grid. The screen is placed in each square grid and compacted and fastened with wooden squares and wooden wedges. There are three specifications of screens pressed in each frame, two of which are wire meshes and one is a nylon mesh. The placement order of the three meshes is a coarse wire mesh at the bottom layer, a fine wire mesh in the middle layer, and a product-selection nylon mesh at the upper layer. The steel mesh at the bottom layer has a large friction on the frame structure, and the screen and the frame wear each other. The wire mesh in the middle layer also wears the lower mesh and the upper nylon mesh. The replacement is frequent, and the horizontal laying of the mesh also affects the surface distribution of the product and the cancellation and mutual exclusion of the amplitude.

Through the setting of the buffer mechanism, it plays a role in limiting the box body, making the box body more stable when moving. Through the setting of the limiting mechanism, it plays a role in fixing the screen. The screen-fastening frame is no longer a horizontal square grid, but an arc-shaped frame with a curvature is made. The difference between the arc-shaped frame and the horizontal frame is that the fastening of the screen is more fitting, and it will not cancel or mutually exclude the vibration force, reduce the friction between the screen and the frame, the surface is flatter, and the product distribution is more uniform, thus solving the problems in the background technique.

[0026] The limiting mechanism 10 includes a screen 101 arranged on the opposite sides of the two connecting blocks 9. First sleeve blocks 102 and second sleeve blocks 103 are fixedly sleeved on both sides of the screen 101. The bottom of the first sleeve block 102 is fixedly connected with a first L-shaped block 104. Both sides of the first L-shaped block 104 are fixedly connected with the connecting block 9.

[0031] Further, as Figure 1 shown, the following preferred technical solutions are provided:

[0032] At the four corners of the bottom of the bottom plate 1, support blocks 13 are fixedly connected. The four support blocks 13 are symmetrically arranged. Through the arrangement of the support blocks 13, the role of supporting the screening device is played, and the stability of the screening device during placement is improved.

[0033] Furthermore, as Figure 1 and Figure 6 shown, the following preferred technical solutions are provided:

[0034] A round block 14 is fixedly connected to the top of the guide rod 73. The cross-sectional area of the round block 14 is larger than that of the guide rod 73. Through the arrangement of the round block 14, the role of limiting the concave block 74 is played, preventing the concave block 74 from detaching from the surface of the guide rod 73.

[0035] Working principle: The user starts the vibration motor 6. The vibration motor 6 drives the box body 2 to vibrate through the wedge block 5. The box body 2 drives the concave block 74 to move downward, so that the concave block 74 slides on the surface of the guide rod 73. When the concave block 74 moves, it will drive the spring 75 to be compressed, thereby improving the stability of the box body 2 during movement, making the box body 2 not easily shift during vibration. When the box body 2 vibrates, it will drive the limiting mechanism 10 to move through the fixing block 8 and the connecting block 9. Then the user pours quartz sand into the inner cavity of the box body 2 through the feed pipe 3. The quartz sand will fall onto the surface of the uppermost screen 101. Then, due to the vibration of the screen 101, the finer quartz sand will fall into the lower screen 101. Since the screen 101 is inclined, the larger particles of quartz sand will slide along the surface of the screen 101 and finally flow out of the inner cavity of the box body 2 through the discharge pipe 4. Since the number of screens 101 is three, the quartz sand can be screened more carefully.
