Description

Technical Field

[0001] The invention relates to the technical field of quartz sand filtration, in particular to a high-purity quartz sand production raw material filtration device. Background Art

[0002] High-purity quartz sand is made of natural crystal stone or high-quality natural quartz stone, which is carefully selected and finely processed. The unique physical and chemical properties of high-purity quartz sand make it play an important role in aviation, aerospace, electronics, machinery and the rapidly developing IT industry today. In particular, its inherent molecular chain structure, crystal shape and lattice change law make it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties, which play an increasingly important role in many high-tech products.

[0003] The patent with the existing authorization announcement number "CN116116798A" discloses a high-purity quartz sand production raw material filtering device, including a flushing and filtering section and a rinsing and filtering section. The flushing and filtering section includes an arc segment, and the arc segment includes an arc-shaped filter plate with a mounting seat and a rotating ring on the top, and scrapers are evenly distributed on the circumference of the rotating ring. The rinsing and filtering section includes a rinsing tank with a material guide channel inside. The high-purity quartz sand production raw material filtering device continuously cleans and filters the raw material in a manner of first flushing and then rinsing. During the flushing process, the raw material is conveyed in a continuous scraping manner, and the arc-shaped filter surface formed by the arc-shaped filter plate limits the conveying path of the raw material. During the rinsing process, the sinking raw material is limited and guided by the inverted eight-shaped material guide channel, so that floating debris cannot adhere to the raw material again. The entire cleaning and filtering process not only ensures the cleaning efficiency of the raw material, but also improves the cleaning effect of the raw material.

[0004] However, there are the following deficiencies in this device:

[0005] During the production of quartz sand, the material often clumps in the quartz sand, which not only affects the filtration of the quartz sand, but also interferes with the subsequent processing. However, when the above device is used, it is difficult to break up the clumps of materials, and only small particles of impurities can be cleaned and filtered, but it is difficult to remove large particles of impurities and large pieces of unqualified materials in the quartz sand, and the filtration is not comprehensive enough;

[0006] The above-mentioned device adopts a water washing and filtering method when filtering the quartz sand. After washing and filtering the quartz sand, the quartz sand is not dried, resulting in the quartz sand being in a wet state after filtration, which affects subsequent processing.

[0038] In this embodiment, a guide rod is provided on one side of the inner side of the two sets of slide grooves 28, and the slider 27 is sleeved on the outer side of the guide rod and slidably cooperates with the guide rod.

The material can be guided by the guide inclined plates to extend its drying path. The discharge pipe is used to discharge the high-purity quartz sand material after filtration and drying, and the quartz sand can flow into the drying bin 71 through the guide hole.

[0040] In this embodiment, a vent is opened in the middle of the filter box 1 away from the drying chamber 71, and a dust net is provided on the inner side of the vent for air intake of the device. The intake air flow can be filtered through the dust net to prevent dust from entering the device.

[0041] In this embodiment, a warehouse door is provided in the middle of one end of the filter box 1, a cleaning door is provided on the top of one side of the filter box 13, and a sewage pipe is provided at the bottom of one side of the filter box 1. The warehouse door is used to facilitate cleaning of large-particle impurity materials filtered in the screening slot 22, and the dust filtered by the dust removal net 14 can be cleaned through the cleaning door, and the sewage can be used to discharge the cleaning wastewater through the sewage pipe.

[0042] In this embodiment, a protective plate cooperating with the impact head 93 is provided in the middle of the bottom of the filter screen 8 to protect the filter screen 8 and prevent the filter screen 8 from being directly damaged by the impact head 93 .

[0043] Embodiment 1, as Figure 2-4 As shown, when the quartz sand falls into the screening groove 22, the water flow sprayed out through the nozzle 4 can cooperate with the shaking of the screening plate 21, so that the quartz sand in the screening groove 22 can be shaken and scrubbed, and the stubborn dust on the surface of the quartz sand can be cleaned, thereby improving the dust filtering effect. The cleaned water flow can carry the dust through the filter screen 8 and fall, and finally be discharged from the sewage pipe.

[0044] Embodiment 2, as Figure 2 and 6 As shown, when the screening plate 21 shakes, the impact head 93 can be pulled by the elastic rope 91 to intermittently move upward under the guidance of the movable rod 94. At this time, the arc guide plate 3 can collide with the bottom protective plate of the filter screen 8. The vibration force generated by the collision can promote the material on the top of the filter screen 8 to flow to one side. After the impact head 93 collides with the protective plate, the elastic force of the elastic rope 91 can be used to buffer the tension of the screening plate 21. After the collision is completed, when the elastic rope 91 is relaxed again, the gravity of the sinker 95 can drive the impact head 93 to reset.

[0045] Working principle: When filtering high-purity quartz sand, the device first starts the air pump 15 and the motor 56, then adds the quartz sand from the feed hopper 6 into the device, and the motor 56 drives the gear B57 to rotate, and then the gear B57 drives the meshing gear A54 to control the rotation of the rotating tube 53, and then the rotating tube 53 drives the through-hole tube 52, so that the through-hole tube 52 can stir the feed, and the agglomerated materials can be broken up. At the same time, the air pump 15 can be used to extract gas from the through-hole tube 52, so that the dust generated by stirring can be sucked out through the through-hole tube 52, and the floating dust in the quartz sand can be filtered out;

[0046] After the first filtration, the quartz sand continues to fall and enters the filter box 1. At this time, the quartz sand can be guided by the arc guide plate 3 so that the quartz sand can fall into the two sets of screening slots 22. When the rotating tube 53 rotates, the rotating rod 23 can be driven to rotate, and then the rotating rod 23 drives the incomplete gear 24, so that the incomplete gear 24 can be alternately meshed with the two sets of racks 26, thereby driving the screening plate 21 to swing left and right along the guide of the slide 28. With the swing of the screening plate 21, the quartz sand in the screening slot 22 can be screened and fall by the screen plate 29, and large impurities and unqualified materials can be filtered in the screening slot 22;

[0047] While the quartz sand is shaken and screened, the water pump 10 can be started to operate. The water pump 10 can draw external water flow and transport it to the two groups of nozzles 4 for downward spraying, so as to rinse the quartz sand in the screening slot 22 and clean the dust on the surface of the quartz sand. The cleaning water flow can follow the quartz sand and fall into the top of the filter screen 8. The quartz sand can be filtered again through the filter screen 8. At this time, the cleaning water flow can drive the residual impurities to fall into the bottom of the filter box 1, and be discharged from the sewage pipe through the diversion of the bottom surface of the filter box 1. When the screening plate 21 is shaken left and right, the impact head 93 can be pulled by the connection of the elastic rope 91 to intermittently impact and vibrate the filter screen 8, so as to promote the flow of materials on the top of the filter screen 8 and prevent material accumulation;

[0048] The quartz sand after cleaning and filtration can enter the drying chamber 71 from the guide hole, and then flow downward through the guide of the guide inclined plate, and the electric heating wire 73 is started. At this time, the air pump 15 draws the air flow and can filter the dust through the dust removal net 14 in the filter box 13, and the exhaust air flow after filtration can be guided into the heating chamber 74, and heated by the electric heating wire 73, so that the hot air can be discharged from the exhaust pipe 72 to dry the quartz sand flowing in the drying chamber 71, and the filtered and dried quartz sand can be discharged through the discharge pipe.
