[0002] The main raw material of quartz sand is quartz stone, also known as silica. Quartz sand has a wide range of uses and can be used in many fields such as glass industry, ceramics and refractory materials, metallurgy industry, construction industry, etc.

[0003] Quartz is mined from mines, and after preliminary sorting and washing, it enters the crusher for primary and secondary crushing, breaking large pieces of quartz into smaller particles. Since quartz sand often contains magnetic materials such as iron, it needs to be removed through the iron removal process, and then other impurities in the quartz sand are further removed through flotation, acid washing and other processes, and finally the finished quartz sand is obtained after dehydration and drying.

[0004] During the pickling process of quartz sand, a certain reaction time is required, and it is necessary to ensure that the quartz sand in the pickling device can be pickled thoroughly to ensure the purity of the final quartz sand product. This scheme proposes a quartz sand purification production line that can improve the purity of quartz sand after pickling. Utility Model Content

[0037] Reference Figure 1~Figure 3 The utility model proposes a quartz sand purification acid extraction production line, the production line includes:

[0038] Transport track (not shown);

[0039] The transfer device 100 moves along the transport track, and the transfer device 100 has a rotating platform 110;

[0040] Acid extraction barrel 200, the transfer device 100 drives the acid extraction barrel 200 to move along the transport track, and the acid extraction barrel 200 is located on the rotating platform 110;

[0041] An acid injection device (not shown), the acid injection device injects acid into the acid extraction barrel 200;

[0042] A sand throwing device (not shown) is used to throw sand into the acid extraction barrel 200 after acid injection.

[0043] By adopting the transfer device 100, the quartz sand can be thoroughly cleaned. The transport track connects different process areas. Taking the empty barrel area and the static area as an example, the acid extraction barrel 200 is placed on the transfer device 100 in the empty barrel area. The transfer device 100 drives the acid extraction barrel 200 to move from the empty barrel area to the static area. During the movement, the acid injection and sand throwing process are gradually completed in the acid extraction barrel 200. In the process of throwing sand, the sand throwing device throws sand into the acid extraction barrel 200 from the top of the acid extraction barrel 200. In the process of throwing sand, the rotating platform 110 drives the acid extraction barrel 200 to rotate and receive sand, ensuring that the quartz sand can be evenly scattered in the acid extraction barrel 200, so that the quartz sand can be better in contact with the pickling liquid. When the acid extraction barrel 200 is loaded with sand, the transfer device 100 drives the acid extraction barrel 200 to rotate and gradually transports the acid extraction barrel 200 to the static area. During the transfer process, the rotation of the acid extraction barrel 200 further ensures that the quartz sand is in contact with the pickling solution, thereby improving the purity of the quartz sand after acid immersion.

[0044] Preferably, the acid injection device and the sand throwing device are arranged at a position on the transport track that is relatively close to the empty barrel area, so that the quartz sand can get a longer rotation time on the transport track, ensuring that the quartz sand and the pickling liquid can be fully in contact. Since this solution does not improve the transport track, the acid injection device, and the sand throwing device, they are not reflected in the accompanying drawings. In addition, in order to improve the stability of the acid extraction barrel 200 during rotation, a limit plate 120 is set on the transfer device 100 to produce a fixing effect on the acid extraction barrel 200.

[0045] The above is the overall working method of the quartz sand purification acid extraction production line. Now, the working process of the acid extraction barrel 200 will be described.

[0046] Acid is injected into the acid extraction barrel 200 through the acid inlet pipe 210, and the acid inlet pipe 210 is connected to the acid injection device to directly inject the pickling solution into the barrel body 270. After the acid injection is completed, the lid on the top of the acid extraction barrel 200 is opened, and sand is injected into the acid extraction barrel 200 from the top of the acid extraction barrel 200. During the sand injection process, the acid extraction barrel 200 is rotated so that the quartz sand enters different areas of the acid extraction barrel 200 during the sand injection process, thereby improving the contact effect between the quartz sand and the pickling solution. Since the filter screen 220 divides the barrel body 270 into a first cavity 230 and a second cavity 240 in the axial direction, there is pickling solution in both the first cavity 230 and the second cavity 240, and the quartz sand is located in the first cavity 230 after being injected.

[0047] When the acid extraction barrel 200 has been standing in the static area for a long enough time, the drain port 250 is first opened to discharge the pickling liquid in the acid extraction barrel 200. Under the obstruction of the filter screen 220, the quartz sand is located in the first cavity 230 and will not be discharged with the pickling liquid. Since the fluidity of quartz sand is poor, a water inlet pipe 310 and a nozzle 320 are provided. After the pickling liquid is discharged, the drain port 250 is closed, the sand discharge port 260 is opened, and water is injected into the pickling barrel through the nozzle 320. The water brings the quartz sand out of the sand discharge port 260 to complete the sand discharge.

[0048] During the sand discharge process, the quartz sand itself is fine particles, which are very easy to stick to the inner wall of the barrel 270 after being wetted. Therefore, the barrel 270 is set to a frustum structure that gradually tightens from top to bottom. The water sprayed from the nozzle 320 can wash down the quartz sand adhered to the inner wall. The inclined inner wall makes it easier for the quartz sand to flow to the sand discharge port 260 under the drive of the water flow.

[0049] The filter screen 220 is tilted, and the lower end is located at the sand discharge port 260 to assist in sand discharge. When the amount of quartz sand in the barrel is small, the effect of flushing it out with water is not obvious, so the filter screen 220 is set to a detachable structure. When the quartz sand in the barrel is not easy to flush out, the remaining quartz sand can be directly taken out through the filter screen 220 by removing the filter screen 220. Since the pickling liquid is corrosive, in order to improve the safety of removing the filter screen 220, a lifting ring 221 is set on the filter screen 220, and the filter screen 220 can be lifted out of the acid extraction barrel 200 without contact by using tools such as hooks.

[0050] In addition, the truncated cone structure of the barrel body 270 makes the top cross-sectional area large and the bottom cross-sectional area small. Therefore, the water inlet pipe 310 at the top can enclose the space in the middle after it is enclosed to allow the filter 220 to pass through, and the water inlet pipe 310 will not affect the removal of the filter 220.

[0051] In order to prevent quartz sand from spilling from the edge into the second cavity 240 during the process of lifting the filter screen 220 , a barrier 222 is provided at the edge of the filter screen 220 , and the barrier 222 forms a relief at the sand discharge port 260 .

[0052] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
