CONCRETE IMPLEMENTATION

[0025] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art will understand that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0026] The utility model provides a kind of magnesite calcination dust collection device, comprising:

[0027] Square tube 1, preset on the feed hopper of calcination equipment;

[0028] Dust suction port 2 is formed on the side wall of the square tube 1;

[0029] First cylinder 3 is located on one side of the square tube 1;

[0030] Connecting pipe 4, one end is communicated with the square tube 1, and the other end is communicated with the first cylinder 3;

[0031] The two ends of connecting pipe 4 are fixedly communicated with square tube 1 and first cylinder 3 respectively, under the action of connecting pipe 4, gas in square tube 1 can flow into first cylinder 3;

[0032] Collecting shell 5 is located at the lower end of the first cylinder 3, and is communicated with the first cylinder 3;

[0033] Collecting shell 5 is threadedly connected with first cylinder 3, can be relatively fixed, and collecting shell 5 can collect magnesite dust, which is convenient for staff to collect;

[0034] Second cylinder 6 is arranged through the upper wall of the first cylinder 3;

[0035] Second cylinder 6 is fixedly penetrated through the upper wall of first cylinder 3, and can be relatively fixed with first cylinder 3;

[0036] Filter cloth bag 7 is arranged in the first cylinder 3, and is fixedly connected with the lower end surface of the second cylinder 6;

[0037] Sliding rod 8, one end is fixedly connected with the lower surface in the filter cloth bag 7, and the other end penetrates the upper wall of the second cylinder 6;

[0038] Elastic member 9 is wound and installed on the outer surface of the sliding rod 8, and one end is fixedly connected with the inner upper end surface of the second cylinder 6, and the other end is fixedly connected with the outer surface of the sliding rod 8;

[0039] Exhaust fan 10 is arranged on the outer side wall surface of the first cylinder 3, and the air inlet end is communicated with the second cylinder 6;

[0040] When the air extractor 10 is started, the air in the second cylinder 6 and the first cylinder 3 can be sucked to be in a negative pressure state, at this time, the magnesite dust can enter into the square tube 1 from the dust suction port 2, and then enter into the first cylinder 3 from the connecting pipe 4, at this time, the filter bag 7 can filter the dust, and the filtered gas is discharged to the outside from the air outlet end of the air extractor 10, so as to prevent the dust from polluting the working environment, and also to collect the magnesite dust to prevent waste. After the filtering is completed, part of the dust filtered out of the filter bag 7 falls into the collecting shell 5, and the other part adheres to the outer surface of the filter bag 7. At this time, the worker pulls the sliding rod 8 to compress the elastic member 9, and then releases the sliding rod 8. At this time, the elastic member 9 can exert a force on the sliding rod 8 to make it slide downward and drive the filter bag 7 to shake, so as to shake off the dust adhered thereto into the collecting shell 5, which is convenient for the worker to collect.

[0041] Specifically, a conveying pipe 11 is arranged through the side wall of the second cylinder 6, the air inlet end of the air extractor 10 is fixedly connected with a hose 12, one end of the hose 12 away from the air extractor 10 is fixedly connected with a ring-shaped member 13, and the ring-shaped member 13 is in communication with one end of the conveying pipe 11 away from the second cylinder 6.

[0042] One end of the conveying pipe 11 is fixedly connected with the second cylinder 6, and can be relatively fixed, and one end of the ring-shaped member 13 is threadedly connected with one end of the conveying pipe 11, so that it can be conveniently disassembled.

[0043] A fixing ring 14 is fixedly installed on the inner surface of the ring-shaped member 13, an upper end surface of the fixing ring 14 is provided with a filter plate 15, a limiting ring 16 is arranged above the filter plate 15 and located in the ring-shaped member 13, and the limiting ring 16 is threadedly connected with the ring-shaped member 13.

[0044] The fixing ring 14 can bear the filter plate 15, at this time, under the action of the air extractor 10, the gas in the second cylinder 6 can enter into the ring-shaped member 13 from the conveying pipe 11, at this time, the filter plate 15 can filter the gas again to prevent dust from remaining in the gas. A driving rod is fixedly installed on the inner surface of the limiting ring 16, and the worker can rotate the limiting ring 16 by rotating the driving rod, so as to disassemble it from the ring-shaped member 13, which is convenient for replacing the filter plate 15. Meanwhile, the limiting ring 16 can limit the filter plate 15 to prevent it from being turned over and affecting the filtering effect of the gas.

[0045] Specifically, two pairs of n-shaped frames 17 are fixedly installed on the lower end of the outer surface of the square tube 1.

[0046] The n-shaped frames 17 can be inserted into the side wall of the feeding hopper to fix the square tube 1 on the feeding hopper, so as to be relatively fixed.

[0047] Specifically, the elastic member 9 is a compression spring.

[0048] Specifically, the filter plate 15 is a microporous ceramic filter plate.

[0049] The microporous ceramic filter plate has tiny pores that can effectively capture dust particles in the air. When the dust-containing gas passes through the microporous ceramic filter plate, the dust particles are blocked and adsorbed, especially in the case of narrow pores, particulate matter is more easily captured. In addition, the surface characteristics of microporous ceramics have strong electrostatic adsorption force, further enhancing their dust capture ability.

[0050] Working principle: In actual use, the n-shaped frame 17 is inserted into the feed hopper of the calcination equipment, which can fix the square tube 1 relative to the feed hopper. At this time, start the air suction machine 10, which can suck the air in the second cylinder 6 and the first cylinder 3 under the action of the conveying pipe 11, the ring-shaped member 13 and the hose 12, so that it is in a negative pressure state. At this time, the workers add the magnesite tailings that need to be calcined into the calcination equipment from the feed hopper. At this time, the dust generated in the feed hopper can enter the square tube 1 through the dust suction port 2, and then enter the first cylinder 3 through the connecting pipe 4. At this time, the filter bag 7 can filter the dust, and the filtered gas enters the second cylinder 6, the conveying pipe 11 and the ring-shaped member 13. At this time, the filter plate 15 can filter the gas again to prevent dust from remaining in the gas. The filtered gas flows into the air suction machine 10 through the hose 12, and is discharged to the outside through the air outlet of the air suction machine 10. After the dust is filtered and collected, the air suction machine 10 is turned off. At this time, part of the dust filtered by the filter bag 7 falls into the collection shell 5, and the other part adheres to the outer surface of the filter bag 7. At this time, the worker pulls the sliding rod 8 to compress the elastic member 9. After compression, the sliding rod 8 is loosened. At this time, the elastic member 9 can exert a force on the sliding rod 8, making it slide downward and shake the filter bag 7, so that the dust adhering to it falls into the collection shell 5, which is convenient for the worker to collect. At the same time, the worker rotates the ring-shaped member 13 to separate it from the conveying pipe 11. At this time, the worker rotates the limiting ring 16 to detach it from the ring-shaped member 13, which is convenient for the worker to replace the filter plate 15. At this time, the worker rotates the collection shell 5 to detach it from the first cylinder 3, which is convenient for the worker to collect the magnesite dust in it, bringing convenience to people.
