Description
Technical Field
[0001] This utility model relates to the field of zinc oxide production technology, specifically to a zinc oxide settling chamber dust circulation device. Background Technology
[0002] Utility model application CN201821535693.4 discloses a dust circulation device for a zinc oxide settling chamber. The dust is cooled by a jacketed structure on the side wall of a dust storage tank for storing cooling water. Dust in contact with the side wall of the dust storage tank cools quickly, but once the tank is full, the central area cannot be cooled promptly, resulting in a long cooling time, uneven dust temperature, and insufficient cooling efficiency. Utility Model Content
[0003] The purpose of this invention is to solve the above-mentioned problems by designing a dust circulation device for a zinc oxide settling chamber.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A dust circulation device for a zinc oxide settling chamber includes: Settling chamber; A dust cooling pool is provided on one side of the dust cooling pool, and the discharge port at the bottom of the settling chamber is connected to the dust cooling pool through the closed-air auger conveyor. The secondary zinc oxide raw material silo is equipped with a bag filter dust collector. The air inlet of the bag filter dust collector is connected to a conveying pipeline, and the feed inlet of the conveying pipeline is located at the bottom of the dust cooling pool. A cooling temperature measuring component is used to perform cooling temperature measurement on a dust cooling pool.
[0005] Dust from the settling chamber is transported to the dust cooling pool via a closed-loop auger conveyor. The bag filter's fan generates negative pressure, drawing dust into the bag filter through the conveying pipeline. The filtered dust falls into the secondary zinc oxide raw material silo through the discharge port. The conveying process generates minimal dust and noise. Dust in the cooling pool is cooled by a cooling and temperature-sensing component. This allows for sufficient contact between the dust and the component, effectively dissipating heat and reducing cooling time, thus improving cooling efficiency. The component also allows for measurement of dust temperatures at different depths, enhancing measurement accuracy.
[0006] Furthermore, the cooling temperature measurement component includes cooling pipes, a cooling jacket is provided inside the dust cooling pool, several cooling pipes are provided and fixedly connected inside the dust cooling pool, one end of the cooling pipes is connected to the cooling jacket, and the other end of the cooling pipes extends through the dust cooling pool. A fixed base is provided on one side of the dust cooling pool, and a water-cooled plate radiator is installed on the fixed base. One end of the water-cooled plate radiator is provided with a water inlet pipe connected to the cooling jacket, and the end of the cooling pipes extending out of the dust cooling pool is provided with a water outlet pipe connected to the other end of the water-cooled plate radiator. A water pump is provided on the water inlet pipe.
[0007] Furthermore, the cooling temperature measurement assembly also includes a cover plate, which is movably connected to the opening of the dust cooling pool. The cover plate is provided with a guide sleeve, and the guide sleeve is provided with a guide slide rod. The cover plate is provided with a multi-stage telescopic cylinder, and a fixing component is installed on the telescopic end of the multi-stage telescopic cylinder. The top end of the guide slide rod is fixedly connected to the fixing component, and a temperature probe is fixedly installed at the bottom end of the guide slide rod. The guide slide rod and the temperature probe are located between two adjacent cooling pipes.
[0008] Furthermore, a fan is connected to one side of the water-cooled radiator via a fixed support rod, and the air outlet of the fan faces the opposite direction to the dust cooling pool.
[0009] By blowing air onto the water-cooled radiator with a fan, the circulating water is cooled, which improves the cooling speed and prevents hot air from blowing onto the dust cooling pool.
[0010] Furthermore, the bottom end of the guide slide is tapered.
[0011] Furthermore, an air intake pipe is connected to one side of the cover plate surface, and a rain cap is connected to the top of the air intake pipe.
[0012] The rain cap prevents water from entering the dust cooling pool through the air intake pipe, thus avoiding dust agglomeration.
[0013] Compared with existing technologies, this technical solution has the following beneficial effects: 1. Cold water is pumped to the cooling jacket and cooling pipes. Dust will come into contact with the inner wall of the dust cooling pool and the cooling pipes, increasing the dust contact area. The dust can be cooled down fully, and the heat of the dust can be discharged in time, reducing the cooling time and improving the cooling efficiency.
[0014] 2. The multi-stage telescopic cylinder drives the guide slide rod to raise and lower the temperature probe, which can measure the temperature of dust at different depths, improving measurement accuracy and avoiding temperature errors. The bottom of the guide slide rod is tapered, which facilitates the insertion of the guide slide rod into the dust and avoids excessive resistance that could cause the guide slide rod to bend and be damaged, thus improving its service life.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0021] This utility model provides, for example Figure 1-3 The illustrated dust circulation device for a zinc oxide settling chamber includes: Settling chamber 1; Dust cooling pool 2, with a closed-loop auger conveyor 3 on one side, and the discharge port at the bottom of settling chamber 1 connected to dust cooling pool 2 through the closed-loop auger conveyor 3; The secondary zinc oxide raw material silo 4 is equipped with a bag filter 5.

Cooling temperature measuring component 7 is used to perform cooling temperature measurement on the dust cooling pool 2.
[0022] Dust in settling chamber 1 is transported to dust cooling pool 2 via closed-loop auger conveyor 3. Bag filter 5 then starts working, and its fan generates negative pressure, drawing dust into the bag filter 5 through conveying pipeline 6. The dust is filtered out and falls into secondary zinc oxide raw material silo 4 through the discharge port. The conveying process generates little dust and low noise. The dust in dust cooling pool 2 is cooled by cooling and temperature measuring components 7. The dust can fully contact the cooling and temperature measuring components 7, allowing the heat from the dust to be discharged in time, reducing cooling time and improving cooling efficiency.

[0024] Water pump 14 starts working, delivering cold water from the water-cooled plate radiator 11 to the cooling jacket 9 through the outlet pipe 13. After the cooling jacket 9 is filled with cold water, the cold water enters the cooling coil 8. After reaching the end of the cooling coil 8, the cold water flows back to the water-cooled plate radiator 11 through the outlet pipe 13. After the dust enters the dust cooling pool 2, the dust will come into contact with the inner wall of the dust cooling pool 2 and the cooling coil 8, increasing the dust contact area. The dust can be fully cooled, and the heat of the dust can be discharged in time, reducing the cooling time and improving the cooling efficiency.

The guide slide rod 17 and the temperature probe 20 are located between two adjacent cooling pipes 8, and the bottom end of the guide slide rod 17 is conical.
[0026] The multi-stage telescopic cylinder 18 starts working.

The guide slide rod 17 drives the temperature probe 20 to rise and fall, which can measure the temperature of dust at different depths, improve the measurement accuracy, and avoid temperature errors. The bottom end of the guide slide rod 17 is conical, which is conducive to the insertion of the guide slide rod 17 into the dust and avoids excessive resistance that may cause the guide slide rod 17 to bend and be damaged, thus improving its service life. The opening of the dust cooling pool 2 is sealed by the cover plate 15 to prevent dust explosion and diffusion.
[0027] Refer to the instruction manual appendix Figure 1 A fan 22 is connected to one side of the water-cooled radiator via a fixed support rod 21, and the air outlet of the fan 22 faces the opposite direction of the dust cooling pool 2.
[0028] Fan 22 starts working and blows air onto the water-cooled plate radiator 11 to dissipate heat from the circulating water, which helps to improve the cooling speed and prevents hot air from blowing onto the dust cooling pool 2.
