Description

Technical Field

[0001] This utility model relates to the field of dust removal devices, specifically a zinc pot dust removal device. Background Technology

[0002] The zinc pot is the core equipment in the hot-dip galvanizing production process. During the galvanizing process, the zinc pot will continuously generate a large amount of flue gas. The flue gas is usually a high-temperature and high-humidity gas, which contains a large amount of dust that is harmful to human health and the environment. The zinc pot dust removal device can separate the dust from the flue gas and plays an important role. However, with the continuous development and expansion of industry, the existing dust removal devices can no longer meet the needs.

[0003] Existing zinc pot dust removal devices have relatively simple structures, and the dust removal methods are usually bag filters and cyclone filters. Bag filters can intercept small dust particles, but the filter bags are prone to clogging, and when dealing with high-temperature, high-humidity, and corrosive zinc pot flue gas, the filter bags have short lifespans and are easily damaged. Cyclone filters rely on centrifugal force to separate dust, but their simple structure can only remove larger dust particles, and the high-temperature flue gas can easily damage equipment such as fans, and the waste heat of the flue gas cannot be effectively utilized. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing zinc pot dust removal device has a simple structure, a single dust removal method, is easy to be damaged, consumes too much energy, and cannot effectively utilize the waste heat of the dust.

[0005] To solve the above technical problems, this solution provides a zinc pot dust removal device, which is achieved through the following technical means: A zinc pot dust removal device includes a base plate and a table. The table has four corners integrally formed with fixing posts fixed to the base plate. A fan is provided on the table. The fan has an air outlet and an air inlet. The air inlet is detachably connected to a transmission pipe. One end of the transmission pipe is connected to a dust collection hood. The base plate has detachable baffles on both sides of the dust collection hood at one end and a water tank at the other end. A water pump is located next to the water tank. The surface of the transmission pipe is wrapped with a cold water pipe. The water pump is connected to the water tank and the cold water pipe. It also includes a filtration structure, which includes an intermediate pipe connected between the dust collection hood and the transmission pipe. The intermediate pipe has a coarse filter plate and a fine filter plate at both ends. The dust collection hood, the coarse filter plate, the intermediate pipe, the fine filter plate and the transmission pipe are detachably connected in sequence. A rotating shaft is provided between the coarse filter plate and the fine filter plate. Rectangular blades are integrally formed at both ends of the rotating shaft. The rectangular blades contact the coarse filter plate and the fine filter plate respectively.

[0006] As an improvement, a pair of limiting grooves are integrally formed on one end of the base plate, with baffles inserted into the limiting grooves and a dust collection hood set between the two baffles.

[0007] As an improvement, the water tank is equipped with an inlet cylinder 1 and an outlet cylinder 1, and the water pump is equipped with an inlet cylinder 2 and an outlet cylinder 2. The inlet and outlet of the cold water pipe are connected to the outlet cylinder 2 and the inlet cylinder 1 respectively through pipes.

[0008] As an improvement, coarse filter plates and fine filter plates are respectively provided with coarse filter holes and fine filter holes.

[0009] As an improvement, limiting holes are provided at both ends of the rotating shaft, and positioning pins are provided at the connection between the surface of the coarse filter plate and the fine filter plate and the rotating shaft. A bearing is also provided between the limiting hole and the positioning pin to make the rotating shaft rotate.

[0010] As an improvement, connecting flanges are provided at the connection points of the dust collection hood, intermediate pipe, transmission pipe and fan, and corresponding through holes are also provided on the coarse filter plate and fine filter plate, all of which are connected by bolts.

[0011] The advantages of this utility model compared with the prior art are: The system features a detachable double-layer filter structure. After the flue gas enters the dust collection hood, it passes through a coarse filter plate and a fine filter plate. The coarse filter plate and the fine filter plate are respectively equipped with coarse filter holes and fine filter holes, which can filter out larger dust particles and smaller dust particles in sequence.

[0012] A rotating shaft is set between the two filter plates. The rectangular blades on the shaft contact the filter plates, and the shaft is rotated by the impact force of the gas, which can promptly scrape away the dust clogging the surface of the filter plates.

[0013] 3. A detachable baffle is provided to prevent excessive gas volume and high temperature and humidity from splashing everywhere when the dust collection hood is working. The detachable design also facilitates disassembly, replacement and cleaning.

[0014] 4. A cold water pipe is wound around the transmission pipe. Cold water enters the cold water pipe through a water pump. During the flue gas transmission process, it can absorb some of the waste heat. After absorbing the waste heat, the cold water enters the water tank through the pipe for use. At the same time, it also reduces the temperature of the flue gas and reduces the possibility of heat damage to equipment such as fans. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] A zinc pot dust removal device, such as Figure 1 As shown, it includes: The base plate 1 and the table 9 are provided. The four corners of the table 9 are integrally formed with fixing posts 27 fixed to the base plate 1. The table 9 is equipped with a fan 8, which is used to absorb flue gas and provide the power required for dust removal. The fan 8 is equipped with an air outlet 12 and an air inlet 13. The air inlet 13 is detachably connected to a transmission pipe 6. One end of the transmission pipe 6 is connected to a dust collection hood 4. Flue gas enters the transmission pipe 6 through the dust collection hood 4. The base plate 1 is detachably equipped with baffles 3 on both sides of the dust collection hood 4 to prevent excessive gas and high temperature and humidity gas from splashing everywhere when the dust collection hood 4 is working. The other end of the base plate 1 is also equipped with a water tank 10. A water pump 11 is located next to the water tank 10. The surface of the transmission pipe 6 is wrapped with a cold water pipe 7. The water pump 11 is connected to the water tank 10 and the cold water pipe 7 to form a cooling heat exchange system.

[0020] like Figure 2 , Figure 3 As shown, the water tank 10 is equipped with an inlet cylinder 19 and an outlet cylinder 20, and the water pump 11 is equipped with an inlet cylinder 21 and an outlet cylinder 22. The inlet 17 and outlet 18 of the cold water pipe 7 are connected to the outlet cylinder 22 and the inlet cylinder 19 respectively through pipes. The water pump 11 obtains cold water from the outside. The cold water enters the cold water pipe 7 through the inlet cylinder 21 of the water pump 11 and then enters the cold water pipe 7 through the pipe connected to the inlet 17 of the cold water pipe 7 through the outlet cylinder 22. After heat transfer, the cold water enters the water tank 10 for storage through the pipe connected to the outlet cylinder 18 and the inlet cylinder 19. When needed, it is output from the outlet cylinder 20. During heat exchange, the flue gas is also cooled.

[0021] like Figure 4 , Figure 5 As shown, the filter structure includes a central tube 5 located at the upper end of the dust collection hood 4. Coarse filter plates 15 and fine filter plates 16 are located at both ends of the central tube 5. The coarse filter plates 15 and 16 are respectively provided with coarse filter holes 28 and fine filter holes 29, used to adsorb and filter dust particles with larger and smaller diameters, respectively. A rotating shaft 23 is also rotatably connected between the coarse filter plates 15 and 16. Rectangular blades 24 are integrally formed at both ends of the rotating shaft 23, contacting the surfaces of each filter plate. Limiting devices are provided at both ends of the rotating shaft 23. Positioning pins 26 are provided at the connection between the surface of the coarse filter plate 15 and the fine filter plate 16 and the rotating shaft 23. A bearing is also provided between the positioning hole 25 and the positioning pin 26 to make the rotating shaft 23 rotate. The rotating shaft 23 rotates by the impact force of the gas flow, and scrapes the particles clogging the surface of the filter plate in real time. A connecting flange 14 is provided at the connection between the dust collection hood 4, the intermediate pipe 5, the transmission pipe 6 and the fan 8. Corresponding through holes 30 are also provided on the coarse filter plate 15 and the fine filter plate 16. All are connected by bolts for easy disassembly and cleaning.

[0022] In the specific implementation of this embodiment: In use, the baffle 3 is inserted into the limiting groove 2, the fan 8 is started, and the flue gas enters from the dust collection hood 4. First, it passes through the coarse filter plate 15. The dense coarse filter holes 28 on the coarse filter plate 15 adsorb and filter out the larger dust particles. Then it passes through the fine filter plate 16. The dense fine filter holes 29 on the fine filter plate 16 adsorb and filter out the smaller dust particles. During the filtration process, the rotating shaft 23 between the two filter plates rotates by the impact force of the airflow. The rectangular blades 24 on the rotating shaft 23 scrape away the dust clogging the surface of the filter plates in real time. The filtered flue gas is transmitted into the fan 8 through the transmission pipe 6. During the transmission process, cold water from the outside is pumped by the water pump 11 into the cold water pipe 7 wrapped around the surface of the transmission pipe 6. The cold water exchanges heat with the flue gas with a large amount of heat in the transmission pipe 6 to reduce the temperature of the flue gas. The cooled water is then transmitted to the water tank 10 for use. The filtered and cooled flue gas is released through the air outlet 12 of the fan 8.

[0023] After use, due to the detachable design of the limiting groove 2 and the baffle 3, the baffle 3 can be removed for cleaning. At the same time, due to the bolt connection, parts such as the coarse filter plate 15, the fine filter plate 16, and the rotating shaft 23 can be removed for cleaning or replacement.
