DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1 to Figure 5 The dust removal and cooling device shown includes a bag filter 1, and the bag filter 1 is connected to an air intake pipe 2. When in use, the flue gas enters the bag filter 1 through the air intake pipe 2, and performs dust removal inside the bag filter 1. Considering that the flue gas has a certain temperature, if the temperature cannot be reduced to meet the requirements and directly enters the bag filter 1, it is easy to increase the loss of the dust bag and shorten its service life. In order to improve the cooling efficiency, a cooling pipe 3 is fixedly connected to the air intake pipe 2, and the cooling pipe 3 surrounds the outside of the air intake pipe 2. When in use, the cooling pipe 3 has a certain length to ensure the coverage area of ​​the cooling and improve the cooling effect of the flue gas.

[0023] The outside of the air inlet pipe 2 is provided with a first suction pipe 5 and a second suction pipe 6 for water circulation inside the cooling pipe 3. A circulating refrigeration device 4 is fixedly connected to the outer wall of the cooling pipe 3. The circulating refrigeration device 4 includes a pump body, an electric refrigeration plate and other structures, which can suck and cool water. The circulating refrigeration device 4 is a common technology in the prior art and will not be described in detail here. The circulating refrigeration device 4 is connected to the cooling pipe 3, the circulating refrigeration device 4 is connected to the top end of the first suction pipe 5, and the bottom end of the second suction pipe 6 is connected to the cooling pipe 3.

[0024] Taking into account that the circulating water source in the structures such as the cooling pipe 3, the first suction pipe 5, and the second suction pipe 6 will experience continuous alternating changes between hot and cold, and impurities are prone to appear, in order to prevent impurities from affecting the operation of the circulating refrigeration device 4, ensure the efficiency of cooling, and improve the dust removal efficiency of the bag dust collector 1, a turntable 8 is rotatably arranged between the first suction pipe 5 and the second suction pipe 6, and a through groove 9 is opened on the turntable 8. The through groove 9 is arranged in plurality, and the plurality of through grooves 9 are evenly distributed around the axis of the turntable 8. The plurality of through grooves 9 cooperate with the first suction pipe 5 and the second suction pipe 6 in turn, and a filter plate 10 is slidably arranged inside the through groove 9.

[0025] In order to reduce the wear of the turntable 8 and improve the sealing between the first suction pipe 5 and the turntable 8, and between the second suction pipe 6 and the turntable 8, rubber pads 18 are fixedly connected to the upper and lower surfaces of the turntable 8. The first suction pipe 5 is attached to the rubber pad 18 at the upper position, and the second suction pipe 6 is attached to the rubber pad 18 at the lower position.

[0026] The outer wall of the first suction pipe 5 is fixedly connected with a second support plate 16, and a motor 17 is fixedly connected to the second support plate 16. A round hole is provided on the second support plate 16 for the driving shaft of the power supply machine 17 to pass through, and the turntable 8 is fixedly connected to the driving shaft of the motor 17. The motor 17 drives the turntable 8 to rotate, so that the plurality of through slots 9 are connected and matched with the first suction pipe 5 and the second suction pipe 6 in turn, and the switching speed is fast, which will not affect the water circulation effect.

[0027] Specifically, when one of the through slots 9 is connected to the first suction pipe 5 and the second suction pipe 6 respectively, the filter plate 10 can filter the impurities in the water circulation process, and the impurities are accumulated inside the through slot 9. When the impurities in the through slot 9 are accumulated more, in order to avoid affecting the efficiency of the water circulation, the motor 17 drives the turntable 8 to rotate, so that the next through slot 9 is connected to the first suction pipe 5 and the second suction pipe 6 respectively, to ensure the efficiency of the water circulation, and continue to filter the impurities. At this time, the through slot 9 with more impurities accumulated can also be cleaned without stopping the operation.

[0028] The utility model provides structures such as a cooling pipe 3, a turntable 8, a through groove 9 and a filter plate 10. The cooling pipe 3 surrounds the outside of the air intake pipe 2 to ensure the coverage area of ​​the cooling and improve the cooling effect of the flue gas. At the same time, the impurities in the water circulation process can be continuously and efficiently filtered to ensure the cooling effect and improve the dust removal efficiency of the bag filter 1.

[0029] In order to improve the stability of the overall structure, a U-shaped frame 7 is fixedly connected between the first suction pipe 5 and the second suction pipe 6 .

[0030] A first support plate 15 is fixedly connected to the top of the inner wall of the through groove 9, a cylinder 12 is fixedly connected to the first support plate 15, a slide rod 11 is slidably connected to the inside of the cylinder 12, the bottom end of the slide rod 11 is fixedly connected to the filter plate 10, a second magnet 14 is fixedly connected to one end of the slide rod 11 located inside the cylinder 12, a first magnet 13 is fixedly connected to the inner wall of the cylinder 12, and the first magnet 13 and the second magnet 14 repel each other.

[0031] When one of the through slots 9 is connected to the first suction pipe 5 and the second suction pipe 6 respectively, the filter plate 10 can filter the impurities in the water circulation process, and the impurities are accumulated inside the through slot 9. When the impurities in the through slot 9 are accumulated more, the water flow will push the slide bar 11 to slide upward inside the cylinder 12; and the motor 17 drives the turntable 8 to rotate, so that the next through slot 9 is connected to the first suction pipe 5 and the second suction pipe 6 respectively, and the through slot 9 with more impurities accumulated is staggered with the first suction pipe 5 and the second suction pipe 6. Due to the repulsive cooperation between the first magnet 13 and the second magnet 14, the slide bar 11 slides downward and resets, and the impurities are pushed out of the through slot 9 for subsequent use.

[0032] By arranging the cylinder 12, the slide rod 11, the first magnet 13 and the second magnet 14 and other structures, impurities inside the through groove 9 are automatically cleaned, thereby improving the processing efficiency.

[0033] A collection container can be placed under the turntable 8 to collect and process the impurities in a centralized manner.
