Description

Technical Field

[0001] The utility model relates to the technical field of separation devices, and specifically, to a zinc ash separation device for zinc oxide preparation. Background Art

[0002] Zinc oxide is a well-known white pigment, commonly known as zinc white, which is produced by grinding zinc ore and other zinc-containing raw materials through a grinding machine. After the zinc ore is ground by the grinding machine, not only zinc oxide is produced, but also some zinc ash and zinc particles (zinc slag) are generated. Zinc ash is a by-product generated in the production process of hot-dip galvanizing plants and electrolytic zinc plants. Its main components are zinc oxide, metallic zinc and some impurities, with strong reducibility and easy to explode when encountering strong oxidants. Therefore, in the separation process, a very closed space and a relatively mature separation device are required.

[0003] When separating zinc oxide and zinc ash, due to the different physical forms, volumes and weights of substances, the separation methods are also different. Currently, in the prior art, cyclone separation is mainly used. Cyclone separation will cause some dust to float up and stay on the cyclone separator. When the equipment is used too many times, a large amount of dust staying on the cyclone separator will block the cyclone separator. At this time, it is necessary to stop the machine and manually clean the dust and zinc slag in the equipment by hand. Due to the large volume of the equipment, the manual cleaning method is rather troublesome, not easy to operate, and will reduce the work efficiency. Summary of the Utility Model

[0004] The utility model provides a zinc ash separation device for zinc oxide preparation, which solves the problem of secondary separation of zinc ash and zinc particles in the related art when manual cleaning is not required.

[0005] The technical solution of the utility model is as follows:

The suction pipeline is connected to the cyclone separator body, and a valve is installed on the suction pipeline. The zinc granule collection box is arranged at the bottom of the grinder for collecting zinc granules separated for the second time. A zinc granule discharge mechanism is arranged on the zinc granule collection box. The suction fan is installed on the outer side wall of the zinc granule collection box, and the suction end of the suction fan is connected to a suction pipe, and the suction pipe is connected to the suction pipeline. The filter screen is detachably arranged in the suction pipe for filtering the air flow entering the suction fan. The discharge pipe is connected to the bottom of the suction pipeline, and a discharge port is opened at the bottom of the discharge pipe. The filter screen is located above the discharge port. The opening and closing control mechanism is arranged on the zinc granule collection box for controlling the opening and closing of the discharge port. The zinc ash collection box is connected to the bottom of the zinc granule collection box, and a zinc ash filter screen is arranged between the zinc granule collection box and the zinc ash collection box for collecting zinc ash filtered by the zinc ash filter screen.

[0007] Preferably, the zinc granule discharge mechanism includes a zinc granule outlet, a zinc granule baffle, an electric cylinder I and a push frame. A zinc granule outlet is opened on the outer side wall of the zinc granule collection box. A zinc granule baffle is hinged at the zinc granule outlet. The electric cylinder I is fixedly installed on the zinc granule collection box. The output end of the electric cylinder I extends into the zinc granule collection box and faces the zinc granule outlet. The push frame is fixedly connected to the output end of the electric cylinder I, and both sides of the push frame are slidably connected to the inner side wall of the zinc granule collection box.

[0008] Preferably, the opening and closing control mechanism includes an electric cylinder II and an opening and closing plate. The electric cylinder II is fixedly installed on the zinc granule collection box. The opening and closing plate is fixedly connected to the output end of the electric cylinder II through a connecting rod for controlling the opening and closing of the discharge port.

[0009] Preferably, the zinc granule baffle is provided with a handle.

[0010] Preferably, the pushing end of the push frame is in a slope shape.

[0011] Preferably, a slidable extraction box is arranged inside the zinc ash collection box.

[0012] The working principle and beneficial effects of the present utility model are as follows:

[0013] In the present utility model, after the zinc ash is separated by the cyclone separator body, the remaining zinc ash and zinc particles inside are not convenient to clean and discharge. At this time, the cyclone separator body is closed, the valve and the exhaust fan are opened, and the extracted zinc ash and zinc particles are filtered at the filter screen of the suction pipe. The gas is discharged from the air outlet through the exhaust fan. The exhaust fan is closed, and the opening and closing plate is extracted. Due to gravity, the extracted zinc ash and zinc particles are discharged from the bottom discharge port. The zinc ash is filtered through the zinc ash filter screen at the bottom of the zinc particle collection box into the zinc ash collection box, and the zinc particles fall into the zinc particle collection box and are collected. Compared with the prior art, secondary separation can be carried out without manual disassembly of the cyclone separator body, reducing manual cleaning operations, improving the utilization rate of the equipment, and preventing internal blockage and accumulation during non-cleaning, which may affect the next separation.

The valve 4 is installed on the suction pipe 3 to control the flow and closure of the suction pipe 3. The zinc granule collection box 5 is arranged at the bottom of the grinder 2 for collecting the zinc granules separated for the second time. A zinc granule discharge mechanism is arranged on the zinc granule collection box 5. The suction fan 6 is installed on the outer side wall of the zinc granule collection box 5, and the air suction end of the suction fan 6 is communicated with an air suction pipe 13. The air suction pipe 13 is connected to the suction pipe 3. The filter screen 7 is detachably arranged in the air suction pipe 13 for filtering the air flow entering the suction fan 6. The discharge pipe 8 is connected to the bottom of the suction pipe 3, and a discharge port is opened at the bottom of the discharge pipe 8. The filter screen 7 is located above the discharge port. The opening and closing control mechanism is arranged on the zinc granule collection box 5 to control the opening and closing of the discharge port. The zinc ash collection box 9 is connected to the bottom of the zinc granule collection box 5, and a zinc ash filter screen 14 is arranged between the collection box and the zinc ash collection box 9 for collecting the zinc ash filtered by the zinc ash filter screen 14.

[0023] In this embodiment, the zinc granule discharge mechanism includes a zinc granule outlet 101, a zinc granule baffle 102, an electric cylinder 103 and a push frame 104. A zinc granule outlet 101 is opened on the outer side wall of the zinc granule collection box 5. A zinc granule baffle 102 is hinged at the zinc granule outlet 101. It should be added that the zinc granule baffle 102 is provided with a handle 10 for opening the zinc granule baffle 102 to discharge the zinc granules separated for the second time. The electric cylinder 103 is fixedly installed on the zinc granule collection box 5. The output end of the electric cylinder 103 extends into the zinc granule collection box 5 and faces the zinc granule outlet 101. The push frame 104 is fixedly connected to the output end of the electric cylinder 103, and both sides of the push frame 104 are slidably connected to the inner side wall of the zinc granule collection box 5. It should be added that the pushing end of the push frame 104 is set to be a slope 11 to prevent the accumulation of zinc granules at the bottom when pushing.

[0024] In this embodiment, the opening and closing control mechanism includes an electric cylinder 201 and an opening and closing plate 202. The electric cylinder 201 is fixedly installed on the zinc granule collection box 5. The opening and closing plate 202 is fixedly connected to the output end of the electric cylinder 201 through a connecting rod for controlling the opening and closing of the discharge port.

[0025] In this embodiment, a slidable extraction box 12 is provided inside the zinc ash collection box 9, and a sealing strip is fixedly installed at the connection with the extraction box 12 to keep the zinc ash from flying around during secondary separation and collection, and to stabilize the sealing performance of the zinc ash collection box 9.

[0026] In summary, the working principle of the zinc ash separation device for zinc oxide preparation is as follows: After the first separation of zinc ash by the cyclone separator body 1, there will be residual zinc ash and zinc particles on the inner wall of the cyclone separator body 1. At this time, the cyclone separator body 1 is closed, and the valve 4 on the suction pipe 3 connected to the cyclone separator body 1 is rotated to open, so that the suction pipe 3 can flow normally. The exhaust fan 6 is turned on, and through the air suction pipe 13 connected to the exhaust fan 6 and the suction pipe 3, the residual or blocked zinc ash and zinc particles inside the cyclone separator body 1 are extracted. The extracted zinc particles and zinc ash are filtered by the filter screen 7 inside the suction pipe, so that the gas flows out through the air outlet of the exhaust fan 6. The zinc ash and zinc particles stay at the bottom of the air suction pipe 13. The electric cylinder two 201 installed on the outer side wall of the zinc particle collection box 5 is activated to retract the opening and closing plate 202 at the discharge port at the bottom of the air suction pipe 13, allowing the separated zinc particles and zinc ash to fall into the zinc particle collection box 5 with the zinc ash filter screen 14. After being filtered by the zinc ash collection box 9, the zinc particles remain in the zinc particle collection box 5, and the zinc ash is filtered into the zinc ash collection box 9. While the zinc ash and zinc particles are falling, the electric cylinder one 103 installed on the outer side wall of the zinc particle collection box 5 is activated to push the push frame 104 with the slope 11, and push the zinc particles and zinc ash falling from the discharge port downward in the direction of the zinc particle baffle 102, so as to avoid the accumulation of zinc particles at the bottom of the discharge port. When no more zinc particles or zinc ash fall from the discharge port, the fan is turned off, and the zinc particle baffle 102 hinged to the zinc particle collection box 5 is pulled, so that the zinc particles after secondary separation and collection are discharged for use from the zinc particle outlet 101 hinged to the zinc particle baffle 102. Then, the slidable extraction box 12 containing zinc ash inside the zinc ash collection box 9 after secondary separation and collection is taken out for use. The zinc particle baffle 102 is closed, the extraction box 12 is placed back in place, and the valve 4 on the suction pipe 3 is rotated to close the suction pipe 3, completing the secondary separation of zinc ash.
