The screw holes are located on one side of the positioning holes, the positioning holes are located on one side of the fixing device, the fixing device is located at one end of the blowpipe, the blowpipe is located at one end of the dust removal outlet, the dust removal outlet is located above the clean air channel, the clean air channel is located above the bag filter dust collection pipe, the bag filter dust collection pipe is located at one end of the ventilation outlet, the ventilation outlet is fixed to the solenoid valve and located above the filter bag, the filter bag is located below the dust removal inlet, the dust removal inlet is located on one side of the air supply pipe, and the air supply pipe is located inside the housing, etc.

[0004] While the aforementioned patents can achieve gas purification and dust removal, remove solid particulate impurities, improve work efficiency, achieve shockproof effect, and are pollution-free, energy-saving, and environmentally friendly, the dust blown down by the gas is mixed together and cannot be classified, causing inconvenience to subsequent cleaning work. Therefore, in order to address the above problems, a cement fly ash dual storage tank with integrated bag dust collection is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1-4As shown, a dual-storage tank for cement fly ash with integrated bag filter dust collection includes a housing 1; several bag cylinders 2 are arranged in a rectangular array inside the housing 1 and are interconnected; an air inlet pipe 3 is provided on the side of the housing 1, passing through the interior and communicating with the bag cylinders 2; an air outlet pipe 4 is provided on the other side of the housing 1; a fan 5 is provided on the surface of the housing 1; the output end of the fan 5 is connected to a conduit 6; one end of the conduit 6 is connected to a horizontal pipe 7; several connecting pipes 8 are equidistantly connected to one side of the horizontal pipe 7; the connecting pipes 8 pass through the interior of the housing 1 and communicate with the bag cylinders 2; a separation component 9 is provided at the bottom of the housing 1; the separation component 9 includes a secondary housing 91; a vibration box 92 is provided inside the secondary housing 91; springs 93 are provided on both sides of the vibration box 92 and one end of the springs 93 is fixedly connected to the inner wall of the secondary housing 91; the vibration box 92 is inclined and has a guide trough 94 at its lower end; a guide plate 95 is provided on the surface of the guide trough 94; a filter screen 96 is provided on the bottom surface of the vibration box 92; and a vibration motor 97 is provided on the side of the vibration box 92.

[0023] During operation, dust-laden gas enters the bag filter cylinder 2 inside the housing 1 through the inlet pipe 3. After the dust is filtered by the bag filter, the fan 5 blows air in the opposite direction to the bag filter cylinder 2 through the duct 6, horizontal pipe 7 and connecting pipe 8 to clean the dust. After cleaning, the mixed dust falls into the vibrating box 92 of the separation component 9. The vibrating motor 97 drives the vibrating box 92 to vibrate along the direction of the spring 93. Cement powder passes through the filter screen 96 and falls into the B discharge box 12. Coal ash slides along the guide chute 94 and through the guide plate 95 into the A discharge box 11. The bag filter and the vibrating screen work together to achieve automatic dust classification and collection, solving the problem of mixed dust that cannot be separated.

[0024] Furthermore, the tilt angle of the guide plate 95 is consistent with the tilt direction of the vibrating box 92, and the aperture of the filter screen 96 is smaller than the diameter of the coal ash particles and larger than the diameter of the cement powder particles.

[0025] During operation, the guide plate 95 tilt angle is consistent with the low end tilt angle of the vibrating box 92, such as 30°. The filter screen 96 aperture is set to 1.2 times the lower limit of the coal ash particle size. During vibration, the coal ash remains on the surface because its size is larger than the aperture, while the cement powder passes through the aperture and falls into the lower layer. The aperture classification and the guide plate 95 angle work together to optimize the material sorting path, thereby improving the separation accuracy of coal ash and cement powder.

[0026] Furthermore, the vibration motor 97 is installed on the high-end side of the vibration box 92, and the springs 93 are symmetrically distributed along both sides of the vibration box 92 with the compression direction perpendicular to the vibration direction.

[0027] During operation, the vibration motor 97 is installed on the high-end side of the vibration box 92, and the springs 93 are symmetrically distributed along the vertical direction on both sides of the vibration box 92. When vibrating, the compression direction of the springs 93 is horizontal and perpendicular to the vibration direction, thus suppressing lateral deviation.

[0028] Furthermore, a diversion valve is installed at the connection between the duct 6 and the horizontal pipe 7, and the outlet pressure of the fan 5 is adjustable and matches the dust removal frequency of the bag filter 2.

[0029] During operation, an electric diversion valve is installed at the connection between the duct 6 and the horizontal pipe 7. The air pressure of the fan 5 is adjusted according to the degree of blockage of the bag cylinder 2, and the high-pressure airflow pulses to clean the dust.

[0030] Furthermore, a discharge trough 10 is opened on the surface of the auxiliary box 91 and is connected to the guide trough 94 through the guide plate 95. The discharge trough 10 is covered on the surface of the auxiliary box 91 and an A discharge box 11 is provided.

[0031] During operation, the guide trough 94 and the discharge trough 10 are smoothly connected by the guide plate 95. The discharge box 11 covers the discharge trough 10 and extends to the external collection position. The coal ash slides into the box along the inclined surface.

[0032] Furthermore, a B discharge box 12 is provided inside the auxiliary box 91. The B discharge box 12 is located directly below the filter screen 96 and is connected to the bottom of the auxiliary box 91.

[0033] During operation, discharge box 12 is located directly below filter screen 96. The box body is connected to the bottom of auxiliary box 91. Cement powder falls freely into the box and is discharged periodically through the bottom valve.

[0034] Working principle: Dust-laden gas enters the bag filter 2 inside the housing 1 through the air inlet pipe 3 and is filtered. The fan 5 blows air in the opposite direction to clean the dust through the duct 6, horizontal pipe 7 and connecting pipe 8. The cleaned mixed dust falls into the vibration box 92 of the separation component 9. The vibration motor 97 drives the vibration box 92 to vibrate along the direction of the spring 93. Cement powder passes through the filter screen 96 and falls into the B discharge box 12. Coal ash slides along the guide chute 94 and through the guide plate 95 into the A discharge box 11, realizing the automatic classification and collection of cement powder and coal ash.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
