Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand pickling, in particular to a quartz sand continuous pickling device. Background Art

[0002] Quartz sand is a non-metallic mineral, a hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white and colorless and translucent. Quartz sand is an important industrial mineral raw material and a non-chemical hazardous substance. It is widely used in industries such as glass, casting, refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics and abrasives.

[0003] In the prior art, when pickling quartz sand, the quartz sand is usually placed in a barrel and soaked in acid. However, the particle sizes of quartz sand are different, and there are different pickling standards for quartz sand with particles of different sizes. The existing device cannot distinguish particles of different sizes in quartz sand for pickling, resulting in inadequate pickling of the quartz sand and reduced pickling efficiency. Secondly, the existing pickling equipment pickles quartz sand with pickling liquid of the same concentration. When the same concentration of acid is used to pickle quartz sand with particles of different sizes, small quartz sand is easily over-pickled, and the acid cannot be effectively used, thereby reducing the efficiency of the use of the acid and having low practicality.

[0004] Therefore, a quartz sand continuous pickling equipment is proposed to solve the above problems. Utility Model Content

The motor drives the multiple stirring rods on the surface of the rotating rod to stir and pickle the quartz sand in the U-shaped support plate, so that the small particles of quartz sand can be pickled evenly and thoroughly. After the pickling is completed, the acid outlet is opened to discharge the pickling liquid in the U-shaped support plate through the acid discharge pipe. The pickling liquid can be filtered through the circular filter to prevent small particles of quartz sand from being discharged. The quartz sand in the collecting tank can be collected by pulling out the collecting trough by using the second handle to open the movable door, and the quartz sand can flow out through the U-shaped support plate by pulling the handle. The electric telescopic rod is started to push the push plate at one end of the electric telescopic rod to push out the quartz sand on the surface of the U-shaped support plate, so as to collect the quartz sand.

[0034] Specifically: the control terminal 101 is electrically connected to each electrically controlled device. The handle 103 can be used to open the movable cover 102 downwards to facilitate the removal of the quartz sand after pickling. The acid outlet 104 is used to discharge the acid solution after use.

[0036] Specifically: the forward and reverse motor 501 is started by the control terminal 101, and the forward and reverse motor 501 can rotate forward and reversely. During the rotation, the threaded rod 502 drives the slider 503 on the surface to move.

One side of the scraper 506 is in contact with the surface of the filter plate 6, so that the quartz sand with a smaller volume is scraped to the inside of the U-shaped support plate 601 through multiple filter holes. The scraper 506 scrapes the filter plate 6 back and forth to the stone on the surface of the filter plate 6. The quartz sand is brushed, screened and filtered, and the scraper brush 506 has a certain softness, which can better scrape and screen the accumulated quartz sand of different sizes. Secondly, when the scraper brush 506 moves back and forth to the top of the inclined filter plate 6, due to its softness, it can move to the edge of the pickling box 1 by touching the larger particles of quartz sand. When it moves in the opposite direction, it can drive the large particles of quartz sand accumulated on both sides, so that a larger volume of quartz sand can be scraped into the inside of the collecting tank 8. During the movement, the connecting block 504 moves inside the limiting groove 401 to play a limiting role.

[0037] In one embodiment, the stirring assembly 7 includes a motor 701, which is fixedly embedded on one side of the outside of the pickling box 1. A rotating rod 702 is fixedly installed on the output end of the motor 701. One end of the rotating rod 702 is connected to one side of the inner wall of the pickling box 1 through a bearing.

The multiple filter ports 802 at the bottom of the inner cavity of the collection tank 8 can filter the added acid solution, so that the acid solution soaking a large volume of quartz sand can be extracted through the acid extraction tube 9. The connecting plates 803 on both sides of the collection tank 8 can be movable inside the T-shaped movable groove 303, and when the collection tank 8 is pulled for use, the two limit blocks 304 can block the two connecting plates 803 to play a limiting role and prevent the collection tank 8 from being pulled out.

[0042] Specifically: starting the electric telescopic rod 10 can make one end of the electric telescopic rod 10 extend. During the extension process, the push plate 1001 connected to one end of the electric telescopic rod 10 can push out the quartz sand at the bottom of the inner cavity of the U-shaped support plate 601. The shape design of the push plate 1001 is also U-shaped, which is consistent with the inner wall of the U-shaped support plate 601, and the quartz sand can be easily pushed out and collected. The inner wall of one side of the pickling box 1 is provided with a movable groove corresponding to the storage of the push plate 1001. When the electric telescopic rod 10 stores the push plate 1001, the push plate 1001 can be stored in the movable groove to avoid blocking the quartz sand screened and dropped from the top filter plate 6. When the water pump 901 is started, the extracted acid can be poured into the interior of the U-shaped support plate 601 through the acid outlet pipe 904, and the acid after pickling can be discharged through the acid discharge pipe 603.

[0044] Specifically: two electric telescopic rods 1101 are started through the control terminal 101, driving the blocking plate 1102 to move downward and fit against one end of the filter plate 6. The bottom of the blocking plate 1102 is designed to be inclined, which can fit with the surface of the inclined filter plate 6, thereby blocking the quartz sand on the surface of the filter plate 6 and preventing the unscreened quartz sand from falling directly into the pickling box 3.

[0045] Working principle: the forward and reverse motors 501, the motor 701, the water pump 901, the electric telescopic rod 10, the electric telescopic rod 2 1101 are electrically connected to the control terminal 101, and the external power supply is connected to the device. When in use, the two electric telescopic rods 2 1101 are started through the control terminal 101 to drive the blocking plate 1102 to move downward and fit against one end of the filter plate 6 to seal the discharge port 105, and then the cover plate 201 is opened through the handle 202 to put the quartz sand that needs to be pickled into the interior of the pickling box 1. At this time, the fallen quartz sand is sieved and filtered through the multiple filter holes on the surface of the filter plate 6, so that smaller particles of quartz sand fall onto the surface of the U-shaped support plate 601. At this time, the control terminal 101 is used to start the forward and reverse motors 501, and the forward and reverse motors 501 can drive the threaded rod 502 to rotate forward and reverse, so that the threaded rod 502 drives the slider 503 on the slider 503 during the rotation. The scraper 505 moves, and the scraping brush 506 at the bottom of the scraper 505 scrapes the quartz sand accumulated on the surface of the filter plate 6 back and forth during the movement. During the scraping process, the quartz sand with smaller particles continues to be scraped and filtered to the surface of the U-shaped support plate 601. During the scraping and screening process, the worker can observe the internal screening situation through the glass observation window 107. After a certain period of screening, the two electric telescopic rods 1101 are started by the control terminal 101 to drive the blocking plate 1102 to move upward for reset. At this time, during the brushing process, the larger quartz sand falls into the collection tank 8 inside the pickling box 2 3 through the discharge port 105 without obstruction. By screening and filtering quartz sand of different particle sizes, the quartz sand can be pickled separately according to the particle size, and different pickling standards are set for quartz sand of different particle sizes, so as to improve the pickling efficiency of the quartz sand;The pickling liquid is added into the interior of the pickling tank 2 3 through the acid inlet 305. At this time, the pickling liquid reaches the surface of the inner cavity of the pickling tank 2 3 and soaks the larger particles of quartz sand in the collecting tank 8 for pickling. After soaking and pickling, the acidity of the acid solution is weakened. The water pump 901 is started by the control terminal 101. The water pump 901 operates and extracts the acid solution in the inner cavity of the pickling tank 2 3 through the acid extraction pipe 9, and is transported to the acid outlet pipe 904 through the connecting pipe 902. The acid outlet pipe 904 can reduce the acidity. A weak acid solution is added to the inside of the U-shaped support plate 601, and the control terminal 101 is used to start the motor 701. The motor 701 drives the multiple stirring rods 703 on the surface of the rotating rod 702 to stir and pickle the quartz sand in the U-shaped support plate 601, so that the small particles of quartz sand can be pickled evenly and thoroughly. After the pickling is completed, the acid outlet 104 is opened to discharge the pickling liquid in the U-shaped support plate 601 through the acid discharge pipe 603, and the pickling liquid can be filtered through the circular filter 602. To prevent the waste caused by the discharge of small particles of quartz sand, the movable door 301 can be opened by using the handle 2 302, and the quartz sand in the collecting tank 8 can be collected by pulling out the collecting tank 8 by pulling out the handle 801. The movable cover 102 is opened by the handle 1 103, and the quartz sand flows out through the U-shaped support plate 601, and the electric telescopic rod 10 is started, so that the push plate 1001 at one end of the electric telescopic rod 10 pushes out the quartz sand on the surface of the U-shaped support plate 601, so as to collect it. The acid solution after the pickling of large particles of quartz sand is used to pickle the small particles of quartz sand, which can prevent the small particles of quartz sand from being over-picked, and the acid solution is effectively used, thereby reducing the amount of acid solution used. The device can extract the acid solution of large particles of quartz sand and pickle the small particles of quartz sand machine through the water pump 901, so that the pickling solution can be recycled again, so that the pickling equipment can continuously pickle quartz sand of different sizes, which improves practicality and is conducive to saving resources. ;
