Description

Technical Field

[0001] The invention relates to the technical field of quartz sand processing equipment, and in particular to a device for recycling pickling waste liquid for processing high-purity quartz sand. Background Art

[0002] Quartz sand is quartz particles obtained by crushing quartz stone. It is a non-metallic mineral and a hard, wear-resistant, and chemically stable silicate mineral. It is milky white or colorless and translucent, with a Mohs hardness of 7. Quartz sand is an important industrial mineral raw material and a non-hazardous chemical. It is widely used in industries such as glass, casting, ceramics, fireproofing, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives, and filter media. Quartz sand undergoes pickling during processing, and the wastewater from pickling is recycled through a recycling device.

[0003] Patent application number CN202221121100.6 discloses a device for recycling high-purity pickling wastewater used in the processing of quartz sand. The device includes a treatment tank with five mounting holes on either side of its inner cavity. The device utilizes a stirring mechanism to agitate the pickling liquid and bring it into contact with the ion exchange resin within a cylindrical filter screen. The reaction between the ion exchange resin and iron ions and the adsorption properties of the ion exchange resin for iron ions enable the device to adsorb and remove the iron ions, thereby improving the device's treatment of the pickling wastewater and, in turn, achieving better pickling results for the quartz sand during recycling. Furthermore, a filter box is provided with a through-slot on one side for inserting a bracket and filter plate, which is sealed with a sealing assembly. This allows the filter plate to be removed from the outside after use, facilitating replacement and cleaning of the filter plate, reducing the difficulty of cleaning the filter plate and improving the device's practicality.

[0004] This patent and the prior art have the following technical problems in actual use: Most pickling waste liquid circulation devices use a filter to filter impurities in the waste liquid, and then collect the filtered waste liquid. However, due to the certain acid concentration in the waste liquid, when filtering through the filter, the waste liquid will cause certain corrosion to the inside of the equipment over time, resulting in a decrease in the filtering effect.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] A device for recycling pickling waste liquid for processing high-purity quartz sand according to a preferred embodiment of the present invention will be described in detail below.

[0022] Example 1, as Figures 1-9 As shown, it includes a circulation drum 1, and a filtering mechanism 2 and an adding mechanism 3 are provided inside the circulation drum 1; A recovery drum 4 and a waste drum 5 are respectively provided on both sides of the circulation drum 1. The filtering mechanism 2 includes a sealing ring 201 fixedly mounted on the inner wall of the circulation drum 1. A filter plate 202 is provided inside the sealing ring 201. The filter plate 202 can rotate inside the sealing ring 201. The adding mechanism 3 includes a movable cylinder 31 disposed inside the circulation cylinder 1, an adding cylinder 32 is disposed inside the movable cylinder 31, a sealing plate 33 is rotatably mounted between the movable cylinder 31 and the adding cylinder 32, and a plurality of sealing plates 33 are arranged in an annular manner. A sealing block 34 is slidably mounted inside the adding cylinder 32, and an adding groove 35 is formed on the surface of the adding cylinder 32. The sealing block 34 is used to seal the adding groove 35. A limiting plate 36 is fixedly mounted on the inner wall of the adding cylinder 32, and the limiting plate 36 is located below the sealing block 34. A mounting cylinder 37 is fixedly mounted on the surface of the movable cylinder 31, and the mounting cylinder 37 can move vertically inside the circulation cylinder 1; A collecting bucket 15 is fixedly installed on the inner top of the circulation cylinder 1 , and a diverter valve 14 is fixedly connected to the top of the circulation cylinder 1 .

[0023] First, the staff controls the installation cylinder 37 to move downward, thereby extracting a certain amount of waste liquid into the circulation cylinder 1. In the process of the waste liquid entering the bottom of the circulation cylinder 1, the waste liquid first passes through the filter plate 202. The filter plate 202 filters the floating matter in the waste liquid to its surface. The filtered waste liquid falls into the interior of the circulation cylinder 1 and is located on the surface of the installation cylinder 37. At this time, the staff injects the neutralizer into the adding cylinder 32. At this time, the neutralizer in the adding cylinder 32 will push the sealing block 34 in the adding cylinder 32 upward. When the sealing block 34 is separated from the adding groove 35, the neutralizer will be injected into the circulation cylinder 1 from the adding groove 35. At this time, the staff controls the installation cylinder 37 to drive the sealing plate 33 to move up and down continuously, so that the waste liquid and the neutralizer can be fully mixed. After the mixing is completed, the staff controls the installation cylinder 37 to move upward quickly again, thereby pushing the waste liquid on the surface of the sealing plate 33 to move upward quickly. When the waste liquid contacts the collecting bucket 15, during the rapid rising process, the waste liquid will contact the bottom of the filter plate 202, thereby impacting the quartz sand impurities in the filter holes of the filter plate 202 and floating them. At the same time, the filter holes at the bottom of the filter plate 202 can filter the waste liquid again. Then the staff controls the water pump inside the waste barrel 5 to suck the floating objects in the waste liquid into its interior through the collecting bucket 15. After the floating objects are absorbed, the staff can control the water pump in the recovery barrel 4 to start and control the diverter valve 14 to open the corresponding side. At this time, the filtered waste liquid will be recovered into the recovery barrel 4 through the collecting bucket 15, and the impurities filtered by the bottom of the filter plate 202 and the sediment in the waste liquid will be left on the surface of the sealing plate 33. At this time, the filter plate 202 is controlled to rotate, and the impurities on its surface can also be transferred to the surface of the sealing plate 33. Then the sealing plate 33 is controlled to rotate to discharge all the impurities out of the circulation barrel 1. By setting up the filtering mechanism 2 and the adding mechanism 3, large particles of solid impurities and sediments can be removed in the preliminary stage, thereby improving the cleanliness of the waste liquid in subsequent treatment. At the same time, by adding a neutralizer to the waste liquid and utilizing the up and down movement of the sealing plate 33, the waste liquid can be effectively pushed and stirred, while improving the mixing effect of the waste liquid and the neutralizer, thereby avoiding excessive acid concentration in the waste liquid, which causes certain corrosion to the circulation drum 1. At the same time, when the sealing plate 33 rises rapidly, the waste liquid can impact the surface of the filter plate 202, thereby flushing out the sediment on the surface of the filter plate 202 and discharging it through the collecting bucket 15. At the same time, when it rises rapidly, the bottom of the filter plate 202 can perform secondary filtration on the waste liquid, ensuring that the fine impurities in the waste liquid are removed, improving the quality of the waste liquid, and reducing pollution in the subsequent treatment process. At the same time, when the sealing plate 33 is rotated open, the sediment remaining in the circulation drum 1 can be discharged from the circulation drum 1, thereby not affecting the subsequent filtration work.

[0024] Example 2, as Figure 3-Figure 9As shown, the rotating shaft of the sealing plate 33 passes through and extends to the interior of the mounting cylinder 37. Several groups of linkage rods 6 are provided inside the mounting cylinder 37. The linkage rods 6 are fixedly connected to the rotating shaft of the sealing plate 33. A linkage ring 7 is rotatably installed on the inner wall of the mounting cylinder 37. The surface of the linkage ring 7 is provided with several groups of grooves for inserting the linkage rods 6. A driving ring 8 is provided below the linkage ring 7. The driving ring 8 is fixedly connected to the linkage ring 7. Several connecting teeth 9 are fixedly installed on one side of the inner wall of the driving ring 8. A driving motor 10 is fixedly installed on the inner bottom of the mounting cylinder 37. A driving gear 11 meshing with the connecting teeth 9 is fixedly installed on the output end of the drive motor 10. The staff controls the drive motor 10 to start. At this time, the output end of the drive motor 10 drives the drive gear 11 to rotate. During the rotation process, the drive gear 11 engages with the connecting tooth 9, and then drives the drive ring 8 to rotate slowly through the connecting tooth 9. During the rotation process, the drive ring 8 drives the linkage ring 7 to rotate synchronously, so that the linkage ring 7 pushes the linkage rod 6 to rotate through the groove on its surface. When the linkage rod 6 rotates, it synchronously drives the sealing plate 33 to rotate through the rotating shaft of the sealing plate 33, so that the sediment of the waste liquid accumulated on the surface of the sealing plate 33 can fall down and be discharged out of the circulation drum 1; The sealing plate 33 is set to seal the movable cylinder 31 when it is in a horizontal state, so that the waste liquid inside the circulating cylinder 1 can move up and down, cooperate with the filter plate 202 to filter the waste liquid. When the neutralizer is injected, the waste liquid moves downward, which can help the neutralizer and the waste liquid to be fully mixed, thereby improving the neutralization effect.

[0025] Example 3, as Figures 1-9 As shown, the top of the circulation drum 1 is fixedly connected to a liquid inlet pipe 12, a water pipe 13 is fixedly connected between the diverter valve 14 and the recovery drum 4 and the waste drum 5, a support base 16 is provided below the circulation drum 1, and the support base 16 is fixedly connected to the surface of the circulation drum 1, a telescopic pipe 17 is fixedly installed between the bottom of the addition drum 32 and the circulation drum 1, and a neutralization box 18 is fixedly installed on the inner bottom of the support base 16. A driving water pump is provided inside the neutralization box 18, and the output end of the driving water pump is fixedly connected to the telescopic pipe 17; The staff connects the waste liquid pipe to the liquid inlet pipe 12 to inject the waste liquid into the circulation drum 1. Then the staff controls the driving water pump in the neutralization box 18 to inject the neutralizer inside the neutralization box 18 into the circulation drum 1 in an equal proportion according to the amount of waste liquid injected, so that the neutralizer and the waste liquid are mixed to reduce the acid concentration in the waste liquid. By injecting a neutralizer, the acid concentration in the waste liquid can be reduced, thereby preventing corrosion to the equipment during circulating filtration.

[0026] Example 4, as Figures 1-9As shown, an electric telescopic rod 19 is fixedly installed on the inner bottom of the support base 16, and the electric telescopic rod 19 passes through the circulation cylinder 1 and is fixedly connected to the bottom of the installation cylinder 37. A rotating motor 20 is fixedly installed on one side of the circulation cylinder 1, and the output end of the rotating motor 20 is fixedly connected to the filter plate 202; When the electric telescopic rod 19 is started, its output end can drive the mounting tube 37 to move up and down.

[0027] Example 5, as Figures 1-9 As shown, the surfaces of the sealing plate 33 are provided with rubber sealing pads, the sealing ring 201 is set to be made of rubber material, and a connecting spring 21 is fixedly installed between the sealing block 34 and the adding cylinder 32; By providing a rubber sealing pad on the surface of the sealing plate 33, the sealing effect of the sealing plate 33 can be improved to prevent leakage.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
