Description

Technical Field

[0001] This utility model belongs to the technical field of dry fog dust suppression equipment, and particularly relates to the filtration device of dry fog dust suppression equipment. Background Technology

[0002] Dry fog dust suppression involves atomizing water into ultrafine droplets with a diameter of less than 10 micrometers. These droplets combine with dust particles in the air to form agglomerates of dust and water mist.

[0003] A search revealed CN221889314U, a filtration device for dry fog dust suppression equipment. Water is supplied through an inlet pipe, impacting a drive impeller, causing it to rotate. This rotation drives a connecting rod, which in turn rotates a mounting plate, which in turn drives a cleaning brush to clean the filter screen. This prevents particulate impurities from accumulating on the filter screen, thus preventing clogging, facilitating water flow, avoiding downtime for cleaning, preventing interference with dust removal, and facilitating the use of subsequent dust suppression systems. However, this application involves a cleaning brush that cleans the filter screen during water supply. This causes impurities to become embedded in the filter screen, and under water pressure, these impurities can easily penetrate the filter screen. Furthermore, cleaning the filter screen requires removal, which affects the water supply filtration effect. Utility Model Content

[0004] The technical problem this invention aims to solve is to replace the filter media without shutting down the machine, while ensuring the filtration effect during the water delivery process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dry fog dust suppression equipment filtration device, including a connecting box, one end of which is connected to a water inlet pipe, and also including a connecting pipe one, a connecting pipe two, and a filter unit. The connecting pipe one is fixedly connected to the upper wall of the connecting box and communicates with the inside of the connecting box. The connecting pipe one is symmetrically distributed. The connecting pipe two is movably connected to the upper part of the connecting pipe one through the filter unit. The other end of the connecting pipe two is used to connect to the main water supply pipe. The filter unit is movably connected between the connecting pipe one and the connecting pipe two.

[0006] Furthermore, the filter units are arranged at uniform intervals along the axial direction of connecting pipe one and connecting pipe two, and adjacent filter units are movably and detachably connected.

[0007] Furthermore, the filter unit includes a sleeve, a connecting box, a connecting ring, and a filter tube. The sleeve is threaded to the outer wall of the connecting tube. The connecting box is fixedly connected to the upper part of the sleeve. The connecting ring is fixedly connected to the upper part of the connecting box. The filter tube is fixedly connected to the upper end of the sleeve and is located at the center inside the connecting box. The outer wall of the filter tube has a strip-shaped hole. The sleeve and the connecting ring are connected through the filter tube inside the connecting box.

[0008] Furthermore, the outer diameter of the connecting ring is equal to the inner diameter of the sleeve, and the sleeve is threaded to the outer wall of the connecting ring of the adjacent filter unit.

[0009] Furthermore, the strip-shaped holes are arranged in a ring at uniform intervals, the filter tube is shaped like a frustum, and the upper end of the filter tube is closed. Filter cotton is detachably installed inside the filter tube.

[0010] Furthermore, the outer wall of the first connecting pipe is provided with a baffle to limit the bottom end face of the sleeve, the middle section of the first connecting pipe is provided with a stop valve, and the middle section of the second connecting pipe is provided with a stop valve.

[0011] With the above structure, the beneficial effects of this utility model are as follows: For the water supply filtration of the dry fog dust suppression equipment, water is supplied to the connecting box through the water inlet pipe. The water supply is diverted by the adjacent connecting pipe one. The connecting pipe two is connected to the main water inlet pipe of the dry fog dust suppression equipment, forming a parallel passage between the main water supply pipe and the connecting box. Multi-stage filtration of the water inlet is achieved by using multiple end-to-end connected filter units. The opening and closing of the water supply passage is controlled by the stop valve one and the stop valve two, which facilitates disassembly, cleaning, and replacement, and allows the filter material to be replaced without stopping the machine during the water supply process.

[0020] like Figure 1-5 As shown, the dry fog dust suppression equipment filtration device includes a connecting box 1, one end of which is connected to a water inlet pipe 2. It also includes a first connecting pipe 3, a second connecting pipe 4, and a filter unit 5. The first connecting pipe 3 is fixedly connected to the upper wall of the connecting box 1 and communicates with the interior of the connecting box 1. The first connecting pipe 3 is symmetrically distributed. The second connecting pipe 4 is movably connected to the upper part of the first connecting pipe 3 through the filter unit 5. The other end of the second connecting pipe 4 is used to connect to the main water supply pipe. The filter unit 5 is movably connected between the first connecting pipe 3 and the second connecting pipe 4. The filter units 5 are evenly spaced along the axial direction of the first connecting pipe 3 and the second connecting pipe 4. Adjacent filter units 5 are detachably movably connected. The water supplied to the connecting box 1 by the first connecting pipe 3 is diverted, connecting the second connecting pipe 4 to the main water inlet pipe of the dry fog dust suppression equipment. Multiple filter units 5 perform multi-stage filtration of the supplied water between the first connecting pipe 3 and the second connecting pipe 4.

[0021] like Figure 3 , Figure 5 and Figure 6 As shown, in order to achieve multi-stage filtration of the transported water, the filtration unit 5 includes a sleeve 6, a connecting box 7, a connecting ring 8, and a filter tube 9. The sleeve 6 is threaded to the outer wall of the connecting pipe 3. The connecting box 7 is fixedly connected to the upper part of the sleeve 6. The connecting ring 8 is fixedly connected to the upper part of the connecting box 7. The filter tube 9 is fixedly connected to the upper end of the sleeve 6 and is located at the center inside the connecting box 7. The outer wall of the filter tube 9 has a strip hole 10. The sleeve 6 and the connecting ring 8 are connected through the filter tube 9 inside the connecting box 7. Filter cotton 11 is detachably installed inside the filter tube 9. The water in the connecting pipe 3 enters the filter tube 9 through the sleeve 6. After being filtered by the filter cotton 11 inside the filter tube 9, the water exits through the strip hole 10 and enters the connecting box 7. The liquid level in the connecting box 7 rises and enters the next connected sleeve 6 through the connecting ring 8.

[0022] The outer diameter of the connecting ring 8 is equal to the inner diameter of the sleeve 6. The sleeve 6 is threaded to the outer wall of the connecting ring 8 of the adjacent filter unit 5, which facilitates the connection of the upper and lower adjacent filter units 5. The strip holes 10 are arranged in a ring with uniform intervals. The filter tube 9 is arranged in a frustum shape, and the upper end of the filter tube 9 is closed.

[0023] like Figure 1 and 2As shown, in order to replace the filter media without shutting down the device, a baffle 12 is provided on the outer wall of the connecting pipe 3 to limit the bottom end face of the sleeve 6. A stop valve 13 is provided in the middle section of the connecting pipe 3, and a stop valve 24 is provided in the middle section of the connecting pipe 4. The water supply of the horizontally parallel connecting pipe 3, filter unit 5 and connecting pipe 4 is controlled by opening and closing the stop valves 13 and 24. When the filter unit 5 needs to be replaced, the stop valves 13 and 24 on one side are closed to stop the water inlet of the connecting pipe 3 and prevent the backflow of water in the connecting pipe 4.

[0024] In actual use, the operator assembles the device and connects different filter units 5 according to the requirements. When connecting the filter unit 5, the filter cotton 11 is inserted into the filter tube 9. The last stage filter unit 5 is connected to one end of the connecting pipe 2 4, and the other end of the connecting pipe 2 4 is connected to the main water inlet pipe of the dry fog dust suppression equipment. In the initial state, the symmetrical stop valve 1 13 and stop valve 2 14 are both in the closed state.

[0025] During filtration, the first shut-off valve 13 and the second shut-off valve 14 on one side are opened, and the water inlet pipe 2 supplies water to the connecting box 1. The water is diverted by the parallel connecting pipe 13. After passing through multiple filter units 5, the water enters the connecting pipe 24 to realize water supply. At the same time, the water is filtered by the filter cotton 11 inside the filter unit 5 and then exits through the strip hole 10 and enters the connecting box 7. The liquid level in the connecting box 7 rises and enters the next connected sleeve 6 through the connecting ring 8.

[0026] When disassembling or replacing filter unit 5, close the shut-off valve 13 and shut-off valve 14 on one side, and disassemble the filter unit 5 on that side. Use the pipeline on the other side to supply water, so as to replace the filter media without stopping the machine.
