Description

Technical Field

[0001] This utility model relates to the field of ore pickling technology, and in particular to an acid pickling, impurity removal and whitening device. Background Technology

[0002] Natural quartz stone refers to stone formed naturally by the earth containing a high proportion of quartz crystals. It is a natural material with high hardness, wear resistance and high temperature resistance. It is often used in building decoration, home design and industrial fields. After natural quartz stone is mined, there are impurities such as oxide skin, yellow skin and black skin on the outer wall. It needs to be acid washed to increase whiteness and improve appearance quality.

[0003] Chinese patent discloses a quartz pickling reactor (authorization announcement number CN208066853U). This patented technology features a steam heating device at the connection between the lower opening of the cylindrical reactor body and the conical bottom, and a spray pickling device at the connection between the upper opening and the hemispherical top. A discharge port is located at the lower end of the conical bottom, and a feed port is located at the center of the hemispherical top. It is widely applicable to the initial purification and impurity removal of quartz.

[0004] This patented technology improves the acid washing efficiency of quartz stone by using the equipment during use. However, there are still shortcomings in its use. During the feeding and unloading process of the equipment, it cannot be used effectively. The equipment can only be put back into use after the feeding and unloading are completed, which reduces the efficiency of the equipment in acid washing quartz stone. In addition, manual feeding and unloading increase the labor intensity. Therefore, those skilled in the art have provided an acid washing, impurity removal and whitening device to solve the problems mentioned in the background art. Utility Model Content

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0046] Example 1

[0047] Please see Figures 1-5 As shown, this embodiment is an acid pickling and whitening device, including a base 100;

[0048] Pickling structure 200 includes pickling tank 201 and return tank 202 connected to pickling tank 201 and with inclined lower inner wall;

[0049] The feeding structure 300 includes a feeding cylinder 301 and a discharge port 303 located at the lower end of the feeding cylinder 301 and connected to the pickling tank 201.

[0050] The feeding structure 500 includes a frame 502 fixed on the upper end of the base 100 and located above the pickling tank 201, three sets of conveying rollers 503 rotatably installed inside the frame 502, a chain plate 504 rotatably sleeved on the outer wall of the conveying rollers 503, push plates 506 fixed on the outer wall of the chain plate 504 and evenly distributed, a motor 508 fixed at the front end of the frame 502 and whose output end is connected to one end of the conveying rollers 503, and a conveyor 501 fixed on the upper part of the base 100 and located on one side below the frame 502.

[0051] One end of the chain plate 504 is raised, and the slope of the raised end is consistent with that of the return groove 202;

[0052] A guide plate 304 is provided on the lower inner wall of the return trough 202 corresponding to the discharge port 303, and a feed port 302 is provided on the upper end of the feed cylinder 301.

[0053] The upper end of the frame 502 is provided with upper rollers 507 that are equidistantly distributed and adhere to the inner wall of the upper end of the chain plate 504, and the lower end of the frame 502 is provided with lower rollers 505 that are equidistantly distributed and adhere to the inner wall of the lower end of the chain plate 504.

[0054] The pickling structure 200 is used;

[0055] Quartz blocks are fed into the feed cylinder 301 through the inlet 302 and pre-stored inside. They are then conveyed to the pickling tank 201 through the outlet 303. At this time, the motor 508 drives the conveyor roller 503 to rotate. It is worth noting that a sprocket is installed on the outer wall of the conveyor roller 503, and the side of the chain plate 504 is engaged with the sprocket via a chain. The conveyor roller 503 drives the sprocket to rotate, and through the transmission between the sprocket and the chain, the chain plate 504 rotates inside the frame 502. The chain plate 504 drives the scraper to push the quartz blocks. The motor 508 operates in stages to further optimize the pickling process and adjust the quartz blocks in the pickling tank. During the pickling process, the quartz stone is pushed and moved, and the accumulated quartz stone and pickling solution are fully structured, avoiding the situation where the quartz stone accumulation and the pickling solution have poor reaction effect. At the same time, when the pallet enters the return tank 202, the quartz stone is lifted, and the pickling solution flows back to the pickling tank 201 through the inclined surface of the return tank 202. The quartz stone passing through the return tank 202 is received by the conveyor 501 and transferred, realizing the effective pickling of quartz stone, removing impurities such as oxide scale, yellow skin, and black skin from the outer wall of quartz stone, playing a whitening role, and improving the appearance quality of quartz stone.

[0056] During the quartz pickling process, the quartz is pushed in stages. After the quartz accumulated on one side of the guide plate 304 is pushed away, the feed cylinder 301 automatically replenishes the quartz through the discharge port 303 and enters the guide plate 304 inside the pickling tank 201. The quartz is automatically fed and unloaded, improving the pickling efficiency of the quartz and eliminating the need for continuous feeding and unloading by personnel, thus reducing labor intensity. The equipment achieves non-stop operation by pre-storing quartz inside the feed cylinder 301 and pushing it in stages by the push plate 506, achieving efficient pickling processing of quartz and avoiding the tedious and time-consuming situation of manual feeding and unloading.

[0057] Example 2

[0058] Please see Figures 1-5 As shown, this embodiment further includes elements beyond those in embodiment 1;

[0059] as well as;

[0060] The filter structure 400 includes a treatment box 401 and a filter cartridge 402 fixed to the inner wall of the upper end of the treatment box 401.

[0061] A suction pump 403 is installed at the upper end of the processing box 401. The suction end of the suction pump 403 is provided with a suction pipe 404 that penetrates the lower end of the feed cylinder 301 and is located inside the pickling tank 201. The output end of the suction pump 403 is provided with a conveying pipe 405 that penetrates the processing box 401.

[0062] A reflux pump 408 is installed at the lower end of the treatment tank 401. A suction pipe 409 penetrating the filter cartridge 402 is installed at the suction end of the reflux pump 408. A reflux pipe 410 penetrating the pickling tank 201 is installed at the output end of the reflux pump 408.

[0063] One end of the processing box 401 is provided with an inspection port 406, and the inspection port 406 is connected to a closing cover 407 by bolts.

[0064] Use the filter structure 400;

[0065] During the pickling process of quartz stone, impurities enter the pickling solution and accumulate over time, affecting the subsequent pickling effect and shortening the pickling solution replacement cycle. During quartz stone pickling, a suction pump 403 draws the pickling solution into the processing tank 401, where it is filtered through a filter cartridge 402. A return pump 408 then draws the filtered pickling solution from inside the filter cartridge 402 back into the pickling tank 201. Impurities in the pickling solution in the pickling tank 201 are transferred to the processing tank 401. The processing tank 401 is periodically cleaned through the inspection port 406, extending the pickling solution replacement cycle and effectively facilitating the pickling process of quartz stone.
