Technical Field
[0001] The utility model relates to the technical field of dust collectors, in particular to a wet explosion-proof dust collector. Background Art
[0002] Dust collectors are devices used to remove solid particulate matter (i.e., dust) from industrial waste gases. These devices are widely used in various industries, including manufacturing, power generation, cement production, steelmaking, chemicals, and mining, to reduce environmental pollution, comply with emission standards, and protect worker health. Existing industrial dust collectors generally include mechanical dust collectors, filter dust collectors, and wet dust collectors.
[0003] Existing wet explosion-proof dust collectors have certain drawbacks. When the required processing volume is large, they cannot effectively capture dust, resulting in low efficiency. When collecting filtered dust, specific machinery must be controlled to collect the dust, which increases energy consumption. When discharging the purified air, water droplets and water vapor are often discharged into the working environment.
[0004] Therefore, a wet explosion-proof dust collector is proposed. Utility Model Content
[0005] The main purpose of the utility model is to provide a wet explosion-proof dust collector, which can effectively solve the problem that when the required processing volume is large, the dust cannot be effectively captured, resulting in low efficiency. When collecting the filtered dust, it is also necessary to control specific machinery to collect the dust, resulting in large source consumption, and water droplets and water vapor are often discharged into the working environment when the purified air is discharged.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a wet explosion-proof dust collector, comprising an outer shell, a first partition plate fixedly installed in the outer shell, a gas gathering hopper fixedly sleeved in the first partition plate, a humidifying cylinder fixedly installed at the lower end of the gas gathering hopper, a spiral sheet fixedly sleeved in the humidifying cylinder, an L-shaped spray pipe is provided on one side of the outer shell, the L-shaped spray pipe passes through the outer shell and the humidifying cylinder and is located inside the humidifying cylinder, a plurality of spray heads are fixedly installed on the surface of the L-shaped spray pipe, and the L-shaped spray pipe is communicated with the spray head.
[0007] Preferably, a dust suction pipe is fixedly mounted on the upper end of the shell, a motor is fixedly mounted on the top end of the dust suction pipe, a second rotating shaft is fixedly mounted on the output shaft of the motor passing through the dust suction pipe, and a plurality of second blades are fixedly mounted on the surface of the second rotating shaft.
[0008] Preferably, a fixing frame is fixedly mounted on the lower end of the humidifying cylinder, a first rotating shaft is rotatably connected to the center of the fixing frame, and a plurality of first blades are fixedly mounted on the surface of the first rotating shaft.
[0009] Preferably, a water storage bucket is fixedly installed at the lower end of the shell, a water inlet pipe is fixedly installed on one side of the water storage bucket, and the water inlet pipe is communicated with the inside of the water storage bucket, a second partition plate is fixedly installed at the lower end of the water storage bucket, a sliding groove is provided in the second partition plate, a gate plate is slidably installed in the sliding groove, a sewage box is fixedly installed at the lower end of the gate plate, a sewage discharge pipe is fixedly installed at the lower end of the sewage box, and the sewage discharge pipe is communicated with the inside of the sewage box, and a valve is fixedly installed on one side of the sewage discharge pipe.
[0010] Preferably, a plurality of first baffle plates are fixedly sleeved on the surface of the humidifying cylinder, a plurality of second baffle plates are fixedly installed in the outer shell, a connecting pipe is fixedly installed on one side of the outer shell, and the connecting pipe is communicated with the interior of the outer shell, an exhaust pipe is fixedly installed on one end of the connecting pipe, and the connecting pipe is communicated with the interior of the exhaust pipe, the lower end of the exhaust pipe is communicated with the interior of the outer shell, a plurality of baffle cylinders are fixedly installed inside the upper end of the exhaust pipe, and an umbrella plate is fixedly installed on the top of the exhaust pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The utility model improves the dust removal efficiency by setting the spiral blades. The L-shaped spray pipe in the humidifying cylinder supplies water to several spray heads for spraying, thereby capturing the dust and attaching it to the water droplets. The spiral blades in the humidifying cylinder can make the dust-laden airflow form a spiral airflow when passing through the humidifying cylinder, so that the dust can be better captured by the water droplets when the spray heads spray, thereby enhancing the adsorption effect and improving the dust removal efficiency.
[0014] 2. The utility model saves energy consumption required for collecting dust in water by providing a fixed frame, a first rotating shaft, and a first blade. The airflow after spraying will continue to be transported to the water storage bucket due to pressure. The first rotating shaft installed in the center of the fixed frame can rotate the first blade when the dust-laden airflow passes through, so that the water in the water storage bucket is stirred to form a vortex, thereby gathering the dust in the water to the center of the water storage bucket, and allowing the dust to enter the dirt storage box, saving energy consumed in collecting dust in the water.
[0015] 3. The utility model prevents water droplets and water vapor from entering the working environment by arranging the first baffle plate, the second baffle plate, the baffle tube and the umbrella plate. Since the pressure in the humidifying tube is relatively high, the filtered air will be transported toward the connecting pipe. When passing through the first baffle plates and the second baffle plates, the water droplets carried by the filtered air when discharged can be captured. The airflow with fine water vapor is then transported to the exhaust pipe through the upper connecting pipe. The baffle tube in the exhaust pipe and the umbrella plate above will capture the fine water vapor and make the water vapor form water droplets that flow downward and then flow back into the water storage bucket from the exhaust pipe, thereby preventing the water droplets and water vapor generated by the filtered air when discharged from entering the working environment.
[0016] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figures 1-6 As shown, a dust suction pipe 20 is fixedly installed on the upper end of the shell 1, and a motor 21 is fixedly installed on the top of the dust suction pipe 20.

[0029] like Figure 1-Figure 7As shown, a water storage bucket 12 is fixedly installed at the lower end of the shell 1, and a water inlet pipe 18 is fixedly installed on one side of the water storage bucket 12, and the water inlet pipe 18 is communicated with the inside of the water storage bucket 12, and a second partition plate 13 is fixedly installed at the lower end of the water storage bucket 12, a sliding groove 14 is provided in the second partition plate 13, and a gate plate 15 is slidably installed in the sliding groove 14, and a sewage box 16 is fixedly installed at the lower end of the gate plate 15, and a sewage pipe 17 is fixedly installed at the lower end of the sewage box 16, and the sewage pipe 17 is communicated with the inside of the sewage box 16, and a valve 28 is fixedly installed on one side of the sewage pipe 17. By adopting the above technical solution, the water inlet pipe 18 can be connected to an external pipeline to fill the water storage bucket 12 with water. After filling with water, the water storage bucket 12 can collect sewage that absorbs dust into the sewage box 16, and filter and discharge the air. Manually push the gate plate 15 to close, and open the valve 28 to discharge the sewage in the sewage box 16 to the designated treatment process.
[0030] like Figure 1-Figure 3 As shown, a plurality of first baffles 8 are fixedly sleeved on the surface of the humidifying cylinder 4, a plurality of second baffles 19 are fixedly installed in the outer shell 1, a connecting pipe 24 is fixedly installed on one side of the outer shell 1, and the connecting pipe 24 is communicated with the interior of the outer shell 1, an exhaust pipe 25 is fixedly installed at one end of the connecting pipe 24, and the connecting pipe 24 is communicated with the interior of the exhaust pipe 25, the lower end of the exhaust pipe 25 is communicated with the interior of the outer shell 1, a plurality of baffles 26 are fixedly installed inside the upper end of the exhaust pipe 25, and an umbrella plate 27 is fixedly installed on the top of the exhaust pipe 25. By adopting the above technical solution, a plurality of first baffles 8 and second baffles 19 can capture the water droplets carried by the filtered air when it is discharged, and the airflow with fine water vapor is then transported to the exhaust pipe 25 by the upper connecting pipe 24, and the baffle 27 above will capture the fine water vapor to form water droplets that flow downward, so that the water vapor flows back into the water storage bucket 12 from the bottom of the exhaust pipe 25.
[0031] like Figure 1-Figure 2 As shown, four brackets 30 are fixedly installed at the lower end of the water storage bucket 12, and an electric control box 29 is fixedly installed on one side of one of the brackets 30. The output end of the electric control box 29 is electrically connected to the input end of the motor 21. By adopting the above technical solution, the electric control box 29 can control the start and stop of the motor 21.
[0032] It should be noted that the present invention is a wet explosion-proof dust collector. When in use, first, install the four brackets 30 in the designated position, connect the electric control box 29 and the motor 21 to the external power supply, connect the water inlet pipe 18 to the external water source, and inject a designated amount of water into the water storage hopper 12;

The L-shaped spray pipe 6 in the humidifying cylinder 4 will supply water to several spray heads 7 for spraying, so as to capture the dust and attach it to the water droplets. The spiral blades 5 in the humidifying cylinder 4 can make the dust-laden airflow form a spiral airflow when passing through the humidifying cylinder 4, so that the spray head 7 can better capture the dust by water droplets when spraying, thereby enhancing the adsorption effect and improving the dust removal efficiency. The airflow after spraying will continue to be transported to the water storage bucket 12 due to pressure. The first rotating shaft 10 installed in the center of the fixing frame 9 can rotate the first blade 11 when the dust-laden airflow passes through, so that the water in the water storage bucket 12 is stirred to form a vortex The dust in the water is gathered to the center of the water storage bucket 12, and the dust enters the dirt storage box 16, saving the energy consumed in collecting dust in the water. The gate piece 15 is manually pushed to close, and the valve 28 is opened to discharge the sewage in the dirt storage box 16 to the designated treatment process. Because the pressure in the humidification cylinder 4 is relatively high, the filtered air will be transported toward the connecting pipe 24. When passing through several first baffles 8 and second baffles 19, the water droplets carried by the filtered air when it is discharged can be captured. The airflow with fine water vapor is then transported to the exhaust pipe 25 from the upper connecting pipe 24. The blocking cylinder 26 in the exhaust pipe 25 and the umbrella plate 27 above it will capture the fine water vapor and make the water vapor form water droplets that flow into the bottom, and then flow into the water storage bucket 12 again from the exhaust pipe 25, thereby preventing the water droplets and water vapor generated by the filtered air when it is discharged from entering the working environment.
