Description

Technical Field

[0001] This utility model relates to the field of sand making tailings screening technology, specifically a multi-stage screening and impurity removal device for sand making tailings. Background Technology

[0002] Tailings from sand production, a byproduct of the manufactured sand production process, mainly originates from a mixture of fine particles and water generated during rock crushing, screening, and sand washing. Its composition is primarily clay minerals (such as kaolinite and montmorillonite), while also containing stone powder, trace amounts of organic matter, and residues of chemical additives.

[0003] In existing sand-making tailings screening processes, the conventional practice is to configure screens of different specifications inside the screening device to achieve graded screening. However, due to the significant differences in particle size distribution of tailings particles, fine particles are easily embedded in the pores of the coarse screen, leading to screen clogging. This phenomenon not only reduces the effective screening area and decreases screening accuracy, but also increases the difficulty of cleaning and maintenance due to the complex screen structure, requiring a significant amount of time and resources. To effectively solve the problem of cumbersome and time-consuming screen cleaning and maintenance, this application proposes a multi-stage screening and impurity removal device for sand-making tailings.

Two side baffles 403 are symmetrically fixedly connected to both sides of the upper surface of the mounting frame 401. By setting the end baffle 402 and the two side baffles 403, they can cooperate with each other to prevent the surrounding mud from flowing into the screening box 1 from the gap between the screen mounting frame 4 and the screening box 1, thus ensuring the screening effect of the tail mud.

By tilting the box body 101, it is convenient to use gravity to assist in screening.

[0026] The feeding component 2 includes a feeding funnel 201, a feeding motor 202 fixedly connected to one side of the top of the feeding funnel 201, a stirring rod 203 rotatably connected to the inner side of the top of the feeding funnel 201, the bottom of the feeding funnel 201 being fixedly connected to the higher end of the upper surface of the box cover 102, the output end of the feeding motor 202 passing through the feeding funnel 201 and fixedly connected to one end of the stirring rod 203, and the outer side of the mounting frame 401 being slidably connected to the inner side of the box body 101. The mounting frame 401 is located on the discharge pipe 10. Above 3, the end baffle 402 is set near the end of the feeding funnel 201. Multiple storage boxes 9 are evenly spaced at the bottom of the inner side with multiple waste discharge holes 901. The storage boxes 9 are slidably connected to the box body 101. The vibrator 5 is fixedly connected to the bottom of the box body 101. The outer side of the telescopic air supply pipe 6 is fixedly connected to the higher end of the box body 101. By setting the telescopic air supply pipe 6, it can move with the jet pipe 1001, which facilitates the stable delivery of high-pressure airflow into the push rod nozzle component 10 to clean the screen 701.

[0027] The movable screen component 7 includes a screen 701, with a sealing gasket mounting plate 702 fixedly connected to one end of the screen 701. The screen 701 is slidably connected to the inner side of the mounting frame 401.

The bottom of multiple vibration springs 8 is fixedly connected to the outer side of the box 101, and the top of the vibration springs 8 is fixedly connected to the mounting frame 401. By setting the rubber sealing gasket 703, tail mud can be prevented from flowing out from the gap between the movable screen component 7 and the screen mounting frame 4, thus affecting the screening effect.

[0028] The push rod nozzle component 10 includes a jet pipe 1001. Two nozzle fixing seats 1002 are symmetrically fixedly connected to both ends of the jet pipe 1001. Multiple jet heads 1003 are evenly spaced and fixedly connected above the jet pipe 1001. One side of the jet pipe 1001 is fixedly connected to the other end of the telescopic air supply pipe 6. Two electric push rods 1004 are symmetrically fixedly connected to one side of each of the two nozzle fixing seats 1002. One end of each electric push rod 1004 is fixedly connected to the higher end of the inner side of the housing 101. By setting two electric push rods 1004, it is easy to drive the jet pipe 1001 to move along the bottom of multiple movable screen components 7, thereby cleaning the fine particles blocked inside the screen holes of multiple movable screen components 7.

[0030] Working principle: The dewatered tailings are poured into the feeding funnel 201. The feeding motor 202 drives the stirring rod 203 to rotate, which in turn drives the tailings to enter the screening box 1 at a uniform speed through the feeding funnel 201. The vibrator 5 works, which drives the screen mounting frame 4 at the top of the multiple vibrating springs 8 to vibrate up and down. The tailings fall into the movable screen component 7 inside the mounting frame 401. Under the action of the vibrator 5 and gravity, they slide down along multiple screens 701 of different specifications for screening. Particles of different sizes fall into multiple storage boxes 9 respectively. Particles that are too large are discharged from the box 101 through the discharge pipe 103 and then through multiple waste discharge holes 9 at the bottom of the storage box 9. 01. Fine impurities in the particles are filtered into the housing 101 and discharged from the housing 101 through the waste discharge pipe 104. When the screen 701 needs to be cleaned, the high-pressure air pump 301 works to compress external air and send it into the telescopic air supply pipe 6 through the air pump supply pipe 302, and then into the jet pipe 1001. Two electric push rods 1004 drive the jet pipe 1001 inside the nozzle fixing seat 1002 to move along the bottom of multiple screens 701. High-pressure airflow is sprayed out through multiple jet heads 1003 to blow out the fine particles blocking the screen holes of the screen 701. The sealing gasket mounting plate 702 is pulled by the movable handle 704, and then the screen 701 is pulled out for replacement and maintenance.
