Description

Technical Field

[0001] This utility model belongs to the field of alumina production technology, and in particular relates to a purification and impurity removal device for recycled alumina. Background Technology

[0002] Bauxite sand, with its advantages of high temperature resistance, non-crushing, dust-free, spherical shape, high permeability, good filling properties, and no silica dust hazard, is a green and environmentally friendly foundry sand. It is made from high-quality bauxite through processes such as calcination, electrofusion, granulation, and screening. To reduce production costs and environmental pollution after use, the recycled bauxite sand is usually processed for reuse. However, the recycled sand often contains a large number of impurities, and the coating on its surface needs to be removed for further processing. Therefore, purification and impurity removal equipment is required to treat the recycled sand and improve its recycling efficiency. However, in practical use, it still has the following drawbacks:

[0003] When recycling used abrasive sand, it is often necessary to remove the coating on its surface. However, during the removal process, a large amount of old sand often needs to be processed at once, resulting in a small contact area between the old sand and the processing reagents or equipment, making it difficult to demold quickly and reducing processing efficiency.

[0004] When old sand is processed and purified by equipment, it often requires multiple processing steps, resulting in a large amount of old sand needing to be processed in one structure and then transferred to another structure for further processing, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to provide a regenerated tartar purification and impurity removal device. Through the purification tank and the washing tank, it solves the problems that when recycling old tartar, multiple structures are needed for step-by-step processing, which is time-consuming and labor-intensive. In addition, when processing a large amount of old sand, the contact area between the equipment or processing reagent and the old sand is small, resulting in low processing efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a device for purifying and removing impurities from recycled abrasive, comprising a purification tank and a washing tank. Multiple stirring rods are driven through and snapped into the bottom of the purification tank. Each stirring rod has multiple sets of stirring blades snapped into its outer circumference from top to bottom. A conveyor belt is rotatably snapped into one side of the top of the purification tank. A washing tank is located on one side of the purification tank. A support frame is snapped into the top of the washing tank. A mesh conveyor belt is rotatably snapped into the bottom of the support frame. Multiple limiting frames are snapped into the top of the support frame. An electromagnet is snapped into the top of each limiting frame. A spray pipe is located at the top of the support frame.

[0008] After a large amount of used sand is poured into the purification tank containing the treatment solution, the sand falls to the bottom of the tank under gravity, while lighter impurities float on the surface, making them easier for workers to clean. The rotation of the agitator blades, driven by the agitator rod, drives the flow of the treatment solution, further moving a large amount of used sand along with it. A first baffle limits the movement of the sand, ensuring that the flow of the treatment solution only moves a portion of the sand per unit time. This allows for thorough contact between the sand and the treatment solution, washing away the coating and other soluble impurities on the sand's surface. When the sand reaches the top of the purification tank with the liquid, it is moved to the bottom of the conveyor belt by the rotation of the agitator blades. The old sand is moved to the top of the mesh conveyor belt by the rotation of the conveyor belt. The mesh conveyor belt then moves the old sand again. During this movement, clean water from the cleaning tank is pumped into the spray pipe by a liquid pump. The clean water washes the old sand again, removing any residual treatment liquid from its surface. When the old sand passes the bottom of the limiting frame, an electromagnet is energized, which attracts iron filings mixed in with the old sand, further removing impurities. After cleaning, the water on the surface of the old sand falls into the cleaning tank through the mesh conveyor belt and is dried by a heating structure. The operation is simple and convenient, and it can perform multiple steps of processing on the old sand simultaneously, greatly improving processing efficiency.

[0009] Furthermore, a first partition is welded and fixed inside the purification tank, and multiple second partitions are welded and fixed from top to bottom on one side of the purification tank. The multiple second partitions are located on one side of the first partition, and multiple stirring rods pass through the top of each second partition. The second partitions are located between two adjacent sets of stirring blades.

[0010] The first partition vertically divides the space inside the purification tank, ensuring that a large amount of old sand is located on one side when it is poured into the purification tank. When the stirring blades drive the treatment liquid to flow, only a portion of the old sand can be moved per unit time, avoiding the simultaneous processing of a large amount of old sand and preventing poor treatment results due to a small contact area between the old sand and the treatment liquid. Furthermore, when the old sand falls to the bottom of the purification tank under gravity, the lighter impurities in the old sand float on the water surface, making it easier for staff to clean the impurities.

[0011] Furthermore, a transmission assembly is fixedly attached to the bottom of the purification tank, a stirring motor is attached to the bottom of the transmission assembly, and multiple stirring rods are attached to the top of the transmission assembly. The stirring rods are connected to the stirring motor via the transmission assembly.

[0012] The stirring motor drives the stirring rod to rotate through the transmission assembly, which in turn drives the stirring blades to rotate. This causes the treatment liquid to flow upwards at an angle on the outer circumference of the stirring rod, further causing the old sand to move upwards at an angle along with the flow of the treatment liquid. The second baffle limits the movement of the old sand, ensuring its residence time in the purification tank and guaranteeing full contact between the old sand and the treatment liquid, thus washing away the coating and other soluble impurities on the surface of the old sand.

[0013] Furthermore, a first conveyor motor is connected through and snapped onto one side of the purification tank. The first conveyor motor is connected to the purification tank and the conveyor belt via a transmission. One end of the conveyor belt is attached to the top of a second partition, and the conveyor belt is located on the other side of the second partition relative to the first partition.

[0014] The first conveyor motor can drive the conveyor belt to rotate. When the old sand flows to the top of the purification tank with the liquid, the old sand can move to the upper side of the conveyor belt under the action of the rotating agitator blades. The rotation of the conveyor belt will drive the old sand to the top of the mesh conveyor belt. When the old sand moves on the upper side of the conveyor belt, the large amount of treatment liquid contained on its surface can flow back into the purification tank under the action of gravity.

[0015] Furthermore, a drain pipe is welded through the bottom of one end of the cleaning pool, a liquid pump is clamped through the bottom of one side of the cleaning pool, a delivery pipe is clamped through the top of the liquid pump, and a spray pipe is clamped through the delivery pipe.

[0016] A liquid pump can pump clean water from the cleaning tank into the spray pipe, and then spray the clean water onto the upper side of the mesh conveyor belt to further clean the old sand that has fallen onto the mesh conveyor belt, washing away the residual treatment liquid on the surface of the old sand.

[0017] Furthermore, a second conveyor motor is connected through one side of the support frame, and the second conveyor motor is connected to the support frame and the mesh conveyor belt for transmission. A waste slag box is connected to the top of one side of the support frame. A cylinder is connected to one end of each limiting frame. A telescopic tube is slidably connected to one end of the cylinder. A push plate is connected to the other end of the telescopic tube. The push plate is attached to the bottom of the electromagnet. The telescopic tube is inserted through one end of the limiting frame. The waste slag box is located at the other end of the multiple limiting frames relative to the cylinder.

[0018] The second conveyor motor drives the rotation of the mesh conveyor belt, which in turn moves the old sand that falls onto the mesh conveyor belt. When the old sand moves to the bottom of the limiting frame, the electromagnet is energized, causing it to attract iron filings from the old sand and collect them inside the limiting frame. At regular intervals, a cylinder drives a push plate to move, pushing the large amount of attracted iron filings to the top of the waste slag box, where they fall under gravity and are collected. As the old sand detaches from the bottom of the spray pipe and continues to move with the mesh conveyor belt, the water on the surface of the old sand can flow back to the washing tank through the mesh conveyor belt and be dried by the heating structure. The operation is simple and convenient, and the equipment can perform multiple steps of processing on the old sand simultaneously, greatly improving processing efficiency.

[0019] This utility model has the following beneficial effects:

[0020] This invention solves the problem of reduced processing efficiency when recycling used abrasive sand by setting up a purification tank. Often, a large amount of old sand needs to be processed at once, resulting in a small contact area between the old sand and the processing reagents or equipment, making rapid demolding difficult. When a large amount of old sand is poured into the purification tank, it is all located on one side. By controlling the stirring blades to move the processing liquid, only a portion of the old sand can be moved per unit time, avoiding the simultaneous processing of a large amount of old sand. This ensures sufficient contact between the old sand and the processing liquid, washing away the coating and other soluble impurities from the surface of the old sand.

[0021] This invention solves the problem of time-consuming and labor-intensive operations caused by multiple processing steps required when purifying and removing impurities from old sand, which often necessitates processing large quantities of old sand in one structure and then transferring them to another. The old sand, falling to the bottom of the purification tank under gravity, has lighter impurities floating on the surface, making them easier for workers to remove. As the old sand moves to the top of the mesh conveyor belt and is carried along by the belt, a liquid pump pumps clean water from the washing tank into the spray pipes, further cleaning the sand and removing residual treatment liquid. Electromagnets then adsorb iron filings mixed in with the sand, further removing impurities. After cleaning, the water on the surface of the old sand falls back into the washing tank via the mesh conveyor belt and is dried using heating structures. The operation is simple and convenient, and the simultaneous multi-step processing of old sand greatly improves processing efficiency. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please see Figure 1-5 As shown, this utility model is a purification and impurity removal device for recycled abrasive sand, including a purification tank 1 and a washing tank 2. Multiple stirring rods 101 are connected through the bottom of the purification tank 1. Multiple sets of stirring blades 106 are fixed from top to bottom on the outer circumference of each stirring rod 101. A conveyor belt 102 is rotatably connected to one side of the top of the purification tank 1. A washing tank 2 is provided on one side of the purification tank 1. A support frame 201 is fixedly connected to the top of the washing tank 2. A mesh conveyor belt 202 is rotatably connected to the bottom of the support frame 201. Multiple limiting frames 209 are fixedly connected to the top of the support frame 201. An electromagnet 210 is fixedly connected to the top of each limiting frame 209. A spray pipe 206 is provided on the top of the support frame 201.

[0031] A large amount of used sand is poured into the purification tank 1 containing the treatment liquid. Under the influence of gravity, the used sand falls to one side of the bottom of the purification tank 1, while the lighter impurities in the used sand float on the surface. The scum is cleaned by the dredging structure. At the same time, the stirring motor 107 drives the stirring rod 101 and stirring blade 106 to rotate, which drives the flow of the treatment liquid. The large amount of used sand moves with the flow of the treatment liquid, thus ensuring that the large amount of used sand and the treatment liquid come into full contact, washing away the film and other soluble impurities on the surface of the used sand. When the used sand flows to the top of the purification tank 1 with the liquid, it moves to the surface of the conveyor belt 102 under the action of the rotation of the stirring blade 106. The rotation of the conveyor belt 102 then moves the used sand until it is washed away by gravity. The sand falls to the top of the mesh conveyor belt 202, and the rotation of the mesh conveyor belt 202 causes the old sand to move again. During the movement, the liquid pump 204 pumps clean water from the cleaning tank 2 into the spray pipe 206. The clean water is sprayed out through the spray pipe 206 to clean the old sand, washing away the residual treatment liquid on the surface of the old sand. Under the action of gravity, the water flows back to the cleaning tank 2 through the mesh conveyor belt 202. When the old sand passes the bottom of the limit frame 209, the electromagnet 210 is energized, so that the electromagnet 210 adsorbs the iron filings mixed in the old sand, further removing impurities from the old sand. After cleaning, the old sand is dried by heating structure, etc., and then moved to the next processing equipment by the mesh conveyor belt 202.

[0032] Among them, such as Figure 1-3 As shown, a first partition 104 is welded and fixed inside the purification tank 1. Multiple second partitions 105 are welded and fixed from top to bottom on one side of the purification tank 1. The multiple second partitions 105 are located on one side of the first partition 104. Multiple stirring rods 101 pass through the top of each second partition 105. The second partitions 105 are located between two adjacent sets of stirring blades 106. A transmission assembly 108 is snapped and fixed at the bottom of the purification tank 1. A stirring motor 107 is snapped at the bottom of the transmission assembly 108. Multiple stirring rods 101 are snapped at the top of the transmission assembly 108. The stirring rods 101 are connected to the stirring motor 107 through the transmission assembly 108. A first conveyor motor 103 is snapped through and fixed on one side of the purification tank 1. The first conveyor motor 103 is connected to the conveyor belt 102 through the purification tank 1. One end of the conveyor belt 102 is attached to the top of a second partition 105. The conveyor belt 102 is located on the other side of the second partition 105 opposite to the first partition 104.

[0033] A large amount of old sand is poured into the purification tank 1 on one side of the first partition 104. Under the action of gravity, the old sand falls to the bottom of the purification tank 1. The lighter impurities in the old sand float on the water surface. The stirring motor 107 drives the stirring rod 101 and stirring blade 106 to rotate through the transmission component 108, so that the treatment liquid flows and further drives the old sand to move upward along multiple second partitions 105, so that the old sand and the treatment liquid can fully contact each other, washing away the film and other soluble impurities on the surface of the old sand. When the old sand moves to the top of the purification tank 1, the first conveying motor 103 drives the conveyor belt 102 to rotate, so that the old sand that has moved to the upper surface of the conveyor belt 102 moves with the conveyor belt 102 until the old sand falls to the top of the mesh conveyor belt 202 under the action of gravity. When the old sand moves on the upper side of the conveyor belt 102, the large amount of treatment liquid contained on its surface flows back into the purification tank 1 under the action of gravity.

[0034] Among them, such as Figure 1 , 4 As shown in Figure 5, a drain pipe 203 is welded through the bottom of one end of the cleaning tank 2. A liquid pump 204 is clamped through the bottom of one side of the cleaning tank 2. A conveying pipe 205 is clamped through the top of the liquid pump 204. A spray pipe 206 is clamped through the conveying pipe 205. A second conveying motor 207 is clamped through the support frame 201. The second conveying motor 207 is connected to the support frame 201 and the mesh conveyor belt 202 through the transmission. A waste residue box 208 is clamped through the top of one side of the support frame 201. A cylinder 211 is clamped through one end of each limiting frame 209. A telescopic tube 213 is slidably clamped through one end of the cylinder 211. A push plate 212 is clamped through the other end of the telescopic tube 213. The push plate 212 is attached to the bottom of the electromagnet 210. The telescopic tube 213 is inserted through one end of the limiting frame 209. The waste residue box 208 is located at the other end of the multiple limiting frames 209 relative to the cylinder 211.

[0035] After the old sand falls onto the mesh conveyor belt 202, the second conveyor motor 207 drives the mesh conveyor belt 202 to rotate, further moving the old sand. The liquid pump 204 pumps clean water from the washing tank 2 through the conveyor pipe 205 to the spray pipe 206 and sprays it onto the surface of the old sand, further cleaning the old sand and removing any residual treatment liquid from its surface. Excess water flows back into the washing tank 2 through the mesh conveyor belt 202. When the old sand is at the bottom of the moving limit frame 209, the electromagnet 210 is energized, causing the electromagnet to... Iron 210 adsorbs iron filings from the old sand, collecting them in the limiting frame 209. At regular intervals, cylinder 211 drives telescopic tube 213 to extend and retract, further driving push plate 212 to move back and forth, pushing the adsorbed iron filings to the top of waste slag box 208, where they fall into the waste slag box 208 for collection under gravity. After the old sand detaches from the bottom of spray pipe 206, it is dried by heating structure and then moved to the next processing equipment by mesh conveyor belt 202.

[0036] The specific working principle of this utility model is as follows: A large amount of old sand is poured into the purification tank 1 on one side of the first partition 104. Under the action of gravity, the old sand falls to the bottom of the purification tank 1, while the lighter impurities in the old sand float on the water surface. The scum is cleaned by the dredging structure. The stirring motor 107 drives the stirring rod 101 and stirring blade 106 to rotate through the transmission component 108, which drives the flow of the treatment liquid. The large amount of old sand moves with the flow of the treatment liquid in sequence, so that the large amount of old sand and the treatment liquid can fully contact each other, washing away the coating and other soluble impurities on the surface of the old sand. When the old sand flows to the top of the purification tank 1 with the liquid, the old sand moves to the surface of the conveyor belt 102 under the action of the rotation of the stirring blade 106. The first conveyor motor 103 drives the rotation of the conveyor belt 102, further driving the old sand to move until the old sand falls to the top of the mesh conveyor belt 202 under the action of gravity. The second conveyor motor 207 drives the second conveyor belt 202 to rotate. The rotation of the mesh conveyor belt 202 further drives the old sand to move. The liquid pump 204 pumps the clean water in the washing tank 2 into the spray pipe 206 through the conveying pipe 205. The clean water is sprayed out through the spray pipe 206 to clean the old sand. Excess water flows back to the washing tank 2 through the mesh conveyor belt 202. When the old sand moves to the bottom of the limiting frame 209, the electromagnet 210 is energized to attract the iron filings in the old sand and collect them in the limiting frame 209. At regular intervals, the cylinder 211 drives the telescopic pipe 213 to extend and retract, which in turn drives the push plate 212 to move back and forth, further driving a large number of iron filings to move to the top of the waste slag box 208 and fall into the waste slag box 208 for collection. After the old sand leaves the bottom of the spray pipe 206, it is dried by the heating structure and then moved to the next processing equipment by the mesh conveyor belt 202.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
