Description

Technical Field

[0001] The present invention relates to the technical field of zinc oxide dust treatment, and in particular to a zinc oxide dust treatment device and method for wet impurity removal. Background Art

[0002] Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. It is insoluble in water but soluble in acids and strong bases. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints and coatings, ointments, adhesives, foods, batteries, flame retardants, and other products. Zinc oxide has a large band gap and exciton binding energy, high transparency, and excellent room-temperature luminescence properties. Zinc oxide dust is treated by spraying water to reduce dust, but the dust reduction products contain various substances, requiring extraction with an extractant and stirring.

[0003] During the use of existing stirring extraction, mechanical equipment drives the material to perform rapid impact. However, when the material is located inside the extraction tank, the internal space of the extraction tank is large, and the mechanical equipment drives the material to perform rapid rotation and impact. Its scope of application is limited. The kinetic energy of the material far away from the mechanical equipment is much smaller than that of the material close to the mechanical equipment. This will cause different material extraction effects at different positions inside the same extraction tank, thereby reducing the use value of the extraction device. Summary of the Invention

[0004] The invention discloses a zinc oxide dust treatment device and method for wet impurity removal, aiming to solve existing technical problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A zinc oxide dust treatment device for wet impurity removal includes an extraction tank and a centralized treatment component, wherein the centralized treatment component includes a centralized cylinder, a drive motor and a stirring shaft, and the cross-section of the centralized cylinder is L-shaped, and two guide holes are opened on the outer side of the centralized cylinder near the top, and the inner walls of the two guide holes are fixedly connected to two guide arc plates, the inner side of the centralized cylinder near the bottom is equidistantly connected to the extrusion plate by a hinge, and each extrusion plate is equidistantly provided with an extrusion spring rod, and the other end of each extrusion spring rod is arranged inside the centralized cylinder, the stirring shaft is located inside the centralized cylinder and is fixedly connected to the stirring rod at equidistant, and the centralized cylinder is fixedly connected to the stirring wire at equidistant, the bottom of the stirring shaft is annularly distributed with layered impact rods, and the layered impact rods are located below the extrusion plate, and the open end of the centralized cylinder located below is vertically downward.

[0007] By providing a centralized processing component, when performing the material extraction operation, the drive motor is started, and the drive motor drives the stirring shaft to rotate rapidly. The stirring rod on the outer side of the rapidly rotating stirring shaft cooperates with the matching wire to realize the extrusion and stirring of the material in the upper section of the concentrated barrel, and the layered impact rod cooperates with the extrusion plate to realize the extrusion and stirring of the material in the lower section of the concentrated barrel. This stirring method ensures that the kinetic energy carried by the material can be impacted within a certain range, and will not cause a large difference in the material extraction effect due to excessive space. At the same time, the same batch of materials are concentrated in the concentrated barrel for extraction, and the kinetic energy passively carried by the material is lost to a minimum due to the limitation of the concentrated barrel, thereby maximizing the impact shear effect between the materials, thereby improving the use value of the extraction device.

[0008] In a preferred embodiment, a protective cover is fixedly connected to the top of the extraction tank, and the stirring shaft is connected to the top inner wall of the protective cover through a bearing, the drive motor is fixedly connected to the top inner wall of the protective cover, the output shaft of the drive motor is fixedly connected to the rotating shaft through a coupling, and the other end of the rotating shaft is connected to the top of the extraction tank through a bearing, the outer side of the rotating shaft is fixedly connected to a driving tooth, the outer side of the stirring shaft is fixedly connected to a driven tooth, and the driving tooth and the driven tooth are meshed with each other.

[0009] In a preferred embodiment, the stirring shaft is located on the outside of the extraction tank and is fixedly connected to two follower frames, and the opposite sides of the two follower frames are fixedly connected to hydraulic cylinders, and the output ends of the two hydraulic cylinders are fixedly connected to clamping rings, which are located on the outside of the concentrating cylinder, and the opposite sides of the two follower frames are fixedly connected with stirring blades at equal distances.

[0010] By providing a follower frame, a hydraulic cylinder and a clamping ring, when the material is unloaded after extraction, the hydraulic cylinder is adjusted to drive the clamping ring to clamp the outside of the concentrating barrel. As a result, when the driving motor is working, the sliding block on the outside of the concentrating barrel rotates in the annular guide rail. The rotation of the concentrating barrel accelerates the separation of the material from the concentrating barrel, thereby avoiding the accumulation of material in the concentrating barrel and causing waste, and further improving the use value of the extraction device.

[0011] In a preferred embodiment, the inner wall of the extraction tank near the bottom of the concentrating cylinder is fixedly connected to an annular guide rail, and the inner wall of the annular guide rail is slidably connected to a plurality of sliding blocks, each of which is fixedly connected to the outer side of the concentrating cylinder.

[0012] In a preferred embodiment, a feed hole is provided on the top of the extraction tank, and a feed pipe is fixedly connected to the inside of the feed hole. A vacuum pump is fixedly connected to the top of the extraction tank near the protective cover, and the vacuum end of the vacuum pump is located inside the extraction tank. A discharge hole is provided at the bottom of the extraction tank, and a discharge pipe is fixedly connected to the inside of the discharge hole. The outside of the discharge pipe is connected to a pipe valve through a flange, and a grounding seat is distributed in a ring at the bottom of the extraction tank.

[0014] By providing a circulation component, when the material is stirred and sheared through the centralized processing component, the circulation pump in the circulation component is started, and the circulation pump drives the material located below the extraction tank to move to the top of the extraction tank, thereby realizing the overall flow of the material inside the extraction tank, so that it can better cooperate with the centralized processing component to complete the material extraction operation. While the circulation pump is working, the delivery pump is started, and the delivery pump guides the material at the bottom of the extraction tank into the hollow mixing barrel and flushes it out through the impact hole, so that the impact between the materials is more intense, further improving the material impact and shearing effect.

[0015] A treatment process for a zinc oxide dust treatment device with wet impurity removal is applied to the above-mentioned zinc oxide dust treatment device with wet impurity removal, and the treatment process comprises the following steps:

[0016] S1: The material is introduced into the extraction tank through the feed pipe, and then the vacuum pump is started to evacuate the inside of the extraction tank;

[0017] S2: Start the driving motor, which drives the stirring shaft to rotate rapidly. During the rapid rotation of the stirring shaft, the stirring rod on the outside cooperates with the matching wire to achieve extrusion and stirring of the materials in the upper section of the centralizing barrel. The layered impact rod cooperates with the extrusion plate to achieve extrusion and stirring of the materials in the lower section of the centralizing barrel.

[0018] S3: When the material is stirred and sheared by the centralized processing component, the circulation pump in the circulation component is started, and the circulation pump drives the material located below the extraction tank to move to the top of the extraction tank, thereby realizing the overall flow of the material inside the extraction tank;

[0019] S4: While the circulation pump is working, the delivery pump is started, which guides the material at the bottom of the extraction tank into the hollow mixing cylinder and flushes it out through the impact hole, making the impact between the materials more intense;

[0020] S5: After the extraction is completed, the pipe valve is opened, and the material flows out through the discharge pipe. The staff collects it and the operation ends.

[0021] From the above, it can be seen that the zinc oxide dust treatment device for wet impurity removal provided by the present invention has the function of starting a drive motor when performing material extraction operation, and the drive motor drives the stirring shaft to rotate rapidly. The stirring shaft is rotating rapidly, and the stirring rod on the outside cooperates with the matching wire to realize the extrusion and stirring of the material in the upper section of the concentrated cylinder, and the layered impact rod cooperates with the extrusion plate to realize the extrusion and stirring of the material in the lower section of the concentrated cylinder. This stirring method ensures that the kinetic energy carried by the material is impacted within a certain range, and will not cause a large difference in the material extraction effect due to excessive space. At the same time, the same batch of materials are concentrated in the concentrated cylinder for extraction, and the kinetic energy passively carried by the material is lost to a minimum due to the limitation of the concentrated cylinder, thereby maximizing the impact and shearing effect between the materials.

During use, the material is driven by mechanical equipment to perform rapid impact. However, when the material is located inside the extraction tank, the internal space of the extraction tank is relatively large. The mechanical equipment drives the material to perform rapid rotation and impact, and its scope of application is limited. The kinetic energy of the material far away from the mechanical equipment is much smaller than that of the material close to the mechanical equipment, which will result in different material extraction effects at different positions inside the same extraction tank.

At the same time, the same batch of materials are concentrated in the concentrated barrel 701 for extraction. The kinetic energy passively carried by the material is lost to a minimum due to the limitation of the concentrated barrel 701, thereby maximizing the impact shear effect between the materials, thereby improving the use value of the extraction device.
