Description

Technical Field

[0001] This utility model relates to the field of zinc oxide impurity removal technology, specifically to a zinc oxide raw material impurity removal device. Background Technology

[0002] Zinc oxide is an inorganic compound with the chemical formula ZnO and a molecular weight of 81.39 g / mol. It is a white solid and a form of zinc oxide. Zinc oxide is insoluble in water and ethanol, but soluble in acids, sodium hydroxide aqueous solution, and ammonium chloride. It is a commonly used chemical additive widely used in the manufacture of plastics, silicate products, synthetic rubber, lubricants, paints, coatings, ointments, adhesives, food, batteries, flame retardants, and other products. The processing of zinc oxide requires precipitation to remove impurities from the raw materials through chemical reactions, thereby improving the purity of the raw materials.

[0003] Existing zinc oxide tends to clump together in high humidity conditions. This can cause larger particles to clog the filter screen, preventing proper filtration and reducing the efficiency of impurity removal. To address this, we have proposed a zinc oxide raw material impurity removal device. Utility Model Content

[0012] Preferably, a discharge door is installed on the outer side of the partition via a hinge, and a sealing sponge strip is provided on the outer side of the discharge door.

[0013] This utility model provides a device for removing impurities from zinc oxide raw materials, which has the following beneficial effects: 1. This zinc oxide raw material impurity removal equipment utilizes a first motor to drive a fourth rotating shaft, which in turn drives a second sprocket. The second sprocket, meshing with a chain, drives a first sprocket, which in turn drives a third rotating shaft. The third rotating shaft, in turn, drives an outer second gear, which, meshing with the first gear, drives the second shaft. The second shaft's rotation drives a crushing roller. The two crushing rollers press against each other to crush the agglomerated zinc oxide, preventing larger particles from clogging the filter screen. Activating the top plate causes the contact rod to vibrate, transmitting the vibration force to a pull plate. This pull plate then vibrates the screen, further ensuring particle passage, improving impurity removal efficiency, and enhancing the device's functionality.

[0014] 2. This zinc oxide raw material impurity removal equipment moves the side plate by activating an electric push rod, which in turn moves the fourth rotating shaft. The movement of the fourth rotating shaft causes the slider to slide inside the second chute. The fourth rotating shaft moves the moving plate, which in turn moves the second shaft. The position of the crushing roller can be adjusted according to the agglomeration. After the solid zinc oxide and strong alkaline solution are poured into the mixing tank, the second motor is activated to rotate the stirring rod. The rotation of the stirring rod can mix and remove impurities from the zinc oxide. After the impurity removal is completed, the mixture is allowed to settle. The solution flows into the through-channel through the outlet filter hole and then is discharged through the output pipe. After the reaction is completed, the impurity metal hydroxide remains inside the tank, thus completing the impurity removal work and improving the functionality of the device.

A second slide groove 24 is opened on one side of the pretreatment box 4. A slider 23 is slidably connected inside the second slide groove 24. The slider 23 is rotatably connected to the fourth rotating shaft 29. Activating the electric push rod 18 can drive the side plate 14 to move, which can drive the fourth rotating shaft 29 to move. The movement of the fourth rotating shaft 29 can drive the slider 23 to slide inside the second slide groove 24.

[0019] The pretreatment box 4 is equipped with a screen 10. A pull plate 16 is fixedly installed at one end of the screen 10. A top plate 21 is fixedly installed on one side of the pretreatment box 4. A vibration motor 20 is fixedly installed at the bottom of the top plate 21.

[0020] A partition 26 is fixedly installed inside the mixing tank 1. A second motor 34 is fixedly installed at the bottom of the partition 26. A stirring rod 25 is fixedly connected to the output end of the second motor 34. After solid zinc oxide and strong alkaline solution are poured into the mixing tank 1, the second motor 34 is started to drive the stirring rod 25 to rotate. The rotation of the stirring rod 25 can drive the zinc oxide to perform mixing and impurity removal. After impurity removal, the mixture is allowed to settle. A through groove 3 is opened in the inner cavity of the mixing tank 1. Multiple liquid outlet filter holes 27 are opened on the inner wall of the mixing tank 1. An output pipe 19 is fixedly installed on the outer side of the mixing tank 1. One end of the output pipe 19 passes through the mixing tank.

At this time, the moving top plate 21 drives the contact rod 22 to vibrate, which can transmit the vibration force to the pull plate 16. The pull plate 16 drives the screen 10 to vibrate, further ensuring that the particles can pass through. Then, the zinc oxide falls into the mixing tank 1. A strong alkaline solution is also poured into the mixing tank 1 to mix with the zinc oxide. The second motor 34 is started, driving the stirring rod 25 to rotate. The rotating stirring rod 25 mixes and removes impurities from the zinc oxide. After impurity removal, the mixture is allowed to settle. The solution flows through the outlet filter 27 into the through-channel 3, and then is discharged through the output pipe 19, thus removing impurities from the zinc oxide raw material. According to the usage requirements, the electric push rod 18 is activated to drive the side plate 14 to move, which can drive the fourth rotating shaft 29 to move. The movement of the fourth rotating shaft 29 causes the slider 23 to slide inside the second sliding groove 24. With the help of the fourth rotating shaft 29, the moving plate 31 slides, which at the same time drives the second rotating shaft 8 to move. The position of the crushing roller 9 can be adjusted according to the agglomeration, and the distance between the two crushing rollers 9 can be adjusted.
