Technical Field
[0001] The utility model relates to the field of zinc oxide production, in particular to raw material mixing equipment for zinc oxide production and preparation. Background Art
[0002] Zinc oxide is an oxide of zinc. It is insoluble in water but soluble in acid and strong alkali. It is a commonly used chemical additive and is widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints and coatings, ointments, adhesives, foods, batteries, flame retardants and other products. Its preparation methods include direct oxidation, indirect oxidation and wet preparation.
[0003] When zinc oxide is prepared by the indirect oxidation method, zinc oxide is prepared by reducing compounds of metallic zinc (such as zinc oxide ore or zinc concentrate). This method includes the steps of ore refining, sintering, reduction, oxidation, etc. During sintering, zinc oxide powder and flux (such as limestone, dolomite, talcum powder) need to be added to a mixing device for mixing to form an ore sintering material, and then the sintering material is sintered at a high temperature to form a solid block.
[0004] However, in the process of mixing zinc oxide powder and flux, as well as in the process of adding and discharging, the existing mixing device will cause part of the zinc oxide powder to float into the air, resulting in a waste of raw materials and polluting the working environment. At the same time, the existing mixing device is prone to clogging of the discharge pipe during discharging, which has certain disadvantages. Utility Model Content

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0020] like Figure 1 , Figure 2 and Figure 4 As shown, a raw material mixing equipment for zinc oxide production and preparation comprises a mixing box 1, a feeding hopper 2 is provided on the upper side of the mixing box 1, a stirring assembly is provided inside, a discharging pipe 3 is provided at the bottom, a top cover 4 is provided on the top of the feeding hopper 2, a motor 5 for driving the stirring assembly to rotate is installed on the top of the mixing box 1, a ventilation pipe 6 is provided on the top of the mixing box 1 on one side of the motor 5, a draft fan 7 is installed inside the ventilation pipe 6, a filter plate 8 is provided at the bottom, a protective net 16 is installed on the top of the ventilation pipe 6, a mounting seat 17 is fixed inside, a rotating shaft 18 is passed through the middle of the mounting seat 17 and rotatably installed, a hand wheel 19 is installed on the top of the rotating shaft 18, a brush 20 is installed after passing through the filter plate 8 at the bottom, an inspection port is provided on the side of the ventilation pipe 6, and a cover plate 21 is detachably installed at the inspection port.
[0021] Open the top cover 4, turn on the induced draft fan 7, so that the external air enters the mixing box 1 from the feed hopper 2, and then is discharged through the ventilation pipe 6. The zinc oxide powder and the flux are added to the mixing box 1 from the feed hopper 2. After the addition is completed, the motor 5 drives the stirring assembly to rotate to achieve the mixing of the zinc oxide powder and the flux. Through the setting of the ventilation pipe 6 and the induced draft fan 7, the dust generated when the zinc oxide powder is added can be effectively prevented from being discharged from the mixing box 1 from the feed hopper 2. The design of the filter plate 8 can make the dust stay inside the mixing box 1. Open the cover plate 21, rotate the shaft 18 through the hand wheel 19, and the shaft 18 drives the brush 20 to rotate, so that the dust on the filter plate 8 can be brushed off, ensuring the smooth ventilation of the ventilation pipe 6. When stirring, cover the top cover 4 and turn off the induced draft fan 7 to prevent the dust generated during the stirring process from drifting into the air.
[0022] like Figure 3 As shown, the stirring assembly includes a stirring shaft 9, on which are mounted a plurality of stirring paddles 10, and a spiral blade 11 is disposed at the bottom of the stirring shaft 9, the bottom of the stirring shaft 9 extends to the inside of the discharge pipe 3, and the spiral blade 11 is located inside the discharge pipe 3, and a valve is installed below the spiral blade 11 of the discharge pipe 3.
[0023] When the motor 5 drives the stirring shaft 9 to rotate in the forward direction, the stirring paddle 10 stirs and mixes the zinc oxide powder and the flux, and the spiral blade 11 transports the material inside the discharge pipe 3 upward to the inside of the mixing box 1. When the mixing is completed, the valve is opened, and the motor 5 drives the stirring shaft 9 to rotate in the reverse direction, so that the spiral blade 11 discharges the material inside the mixing box 1 through the discharge pipe 3.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a fixed box 12 is connected to the bottom of the discharge pipe 3, a plurality of support rods 22 for supporting the mixing box 1 are fixedly connected to the top of the fixed box 12, an opening is provided at the front end of the fixed box 12, a movable plate 13 is provided inside, a rubber pad 23 is bonded to the bottom of the movable plate 13, an electric cylinder 14 for driving the movable plate 13 to move up and down is installed through the top of the fixed box 12, a discharge hole is provided in the middle of the movable plate 13, and a hose 15 connected to the discharge pipe 3 is installed inside the discharge hole.
[0025] The collecting box is placed in the fixed box 12, and the electric cylinder 14 is extended to make the movable plate 13 move downward and abut against the collecting box to achieve the sealing of the collecting box. At this time, the material discharged from the discharge pipe 3 enters the collecting box through the hose 15, which can effectively prevent the dust in the discharge process from floating into the air.
[0026] In specific use, the induced draft fan 7 is turned on, and the zinc oxide powder and flux are added into the mixing box 1, and then the top cover 4 is closed. The motor 5 drives the stirring shaft 9 to rotate forward, and the stirring paddle 10 stirs and mixes the zinc oxide powder and the flux. The spiral blade 11 transports the material inside the discharge pipe 3 upward to the inside of the mixing box 1; after stirring and mixing, the collection box is placed in the fixed box 12, and the electric cylinder 14 is extended to make the movable plate 13 move downward and abut against the collection box. The motor 5 drives the stirring shaft 9 to rotate in the opposite direction, so that the spiral blade 11 discharges the material inside the mixing box 1 through the discharge pipe 3 and the hose 15 into the collection box. The entire mixing, feeding and discharging process can effectively prevent dust from floating into the air, reduce the waste of raw materials, and avoid dust pollution in the working environment; discharging by the spiral blade 11 can effectively avoid the blockage of the discharge pipe 3.
