Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, and particularly relates to an energy-saving bag dust collector for manhole cover processing. Background Art

[0002] A bag dust collector is a dry dust filtering device, which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0025] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] Please refer to Figures 1 - 4 , the present invention provides an energy-saving bag dust collector for manhole cover processing, including a box body 1, a support frame 5 (the support frame 5 is used to support the box body 1, and the two are fixedly connected), and a plurality of flow guide metal plates arranged on the inner wall of the box body 1. An air inlet for air intake is opened on the side surface of the box body 1, and a dust-containing gas input pipe 3 is fixedly connected to the inner wall of the air inlet. A plurality of exhaust ports are opened on the surface of the box body 1, and a purified gas discharge pipe 2 is fixedly connected to the inner wall of the exhaust port. An input mechanism is provided at one end of the dust-containing gas input pipe 3;

[0027] A fixed frame 12 is fixedly connected to the inner wall of the box body 1, and a plurality of filter bags 13 are fixedly connected to the inner wall of the fixed frame 12. A cleaning component for cleaning the filter bags 13 is fixedly connected to the outer surface of the box body 1;

[0028] A hopper 11 is provided at the bottom of the box body 1. A plurality of connecting mechanisms are fixedly connected to the inner wall of the hopper 11. One end of the connecting mechanism is fixedly connected to a flow guide plate 15. A plurality of power mechanisms are fixedly connected to the center of the inner wall of the hopper 11. The output end of the power mechanism is fixedly connected to a transmission rod 19. A plurality of cleaning components for cleaning dust are fixedly connected to the outer surface of the transmission rod 19. A filter bag 13 is provided at the bottom of the hopper 11;

[0029] Through the input mechanism, the dust-containing gas from the outside enters the box body 1 through the dust-containing gas input pipe 3. The speed of the gas is reduced by the collision of the flow guide metal plates, so that the coarse dust particles fall onto the surface of the flow guide plate 15 in the hopper 11. The remaining fine dust particles enter the filter bag 13 along with the gas. Due to the inertia, diffusion, blocking, hooking, static electricity and other effects of the filter material fibers and fabrics, the dust is retained in the filter bag 13. The purified gas escapes outside the bag and is discharged through the purified gas discharge pipe 2. When dust needs to be cleaned, the cleaning component deforms and shakes the filter bag 13 and penetrates the filter material to clean the ash, so that the dust falls onto the surface of the flow guide plate 15 in the hopper 11. Then, the power mechanism makes the transmission rod 19 reciprocate, thereby driving the cleaning component to move on the surface of the flow guide plate 15, so that the dust is brushed off. At the same time, under the action of the cleaning component and the connecting mechanism, the flow guide plate 15 itself shakes slightly, which is convenient for the dust to fall, and avoids the problem of dust remaining in the hopper 11.

[0030] Specifically, the cleaning component includes a support base 6 fixedly connected to the surface of the box body 1, an air storage tank 7 fixedly connected to the surface of the support base 6, a plurality of ejectors 8 fixedly connected to the surface of the air storage tank 7, a gas delivery pipe 9 fixedly connected to the output end of the ejector 8, an electromagnetic pulse valve 10 provided at the head end of the gas delivery pipe 9, and a plurality of openings formed on the surface of the gas delivery pipe 9. The air storage tank 7 is in communication with the ejector 8;

[0031] By opening the electromagnetic pulse valve 10, the gas in the air storage tank 7 enters the gas delivery pipe 9 through the ejector 8 and is discharged through the openings, causing the filter bag 13 in the box body 1 to deform and vibrate to achieve the effect of dust cleaning.

[0032] Specifically, the input mechanism is composed of a fan 4. Through the fan 4, the external gas enters the box body 1 through the dust-containing gas input pipe 3 (the fan 4 is in through connection with the dust-containing gas input pipe 3).

[0033] Specifically, a plurality of mounting holes 14 are formed on the surface of the ash hopper 11, and a plurality of screw holes matching the mounting holes 14 are formed at the bottom end of the box body 1. The inner wall of the screw hole is threadedly connected with a bolt for fixing the ash hopper 11. When the parts in the ash hopper 11 are damaged, the staff can remove the bolt with tools to separate the ash hopper 11 from the box body 1, facilitating the maintenance or replacement of the parts on the inner wall of the ash hopper 11 (a sealing gasket is provided at the connection between the ash hopper 11 and the box body 1).

[0034] Specifically, the connection mechanism includes a connecting pipe 21 fixedly connected to the inner wall of the ash hopper 11, a spring fixedly connected inside the connecting pipe 21, and a connecting base rod 22 fixedly connected to one end of the spring. One end of the connecting base rod 22 is fixedly connected to one end of the deflector 15. When the deflector 15 is stressed, the spring deforms through the connecting base rod 22, thereby causing itself to shake.

[0035] Specifically, the power mechanism includes a protective pipe 18 fixedly connected to the inner surface of the ash hopper 11 and an electric telescopic rod fixedly connected inside the protective pipe 18. One end of the electric telescopic rod is fixedly connected to a transmission rod 19. The cleaning component includes a plurality of connecting rods 17 fixedly connected to the surface of the transmission rod 19 and a cleaning brush 16 fixedly connected to one end of the connecting rod 17. The bristles of the cleaning brush 16 are in contact with the deflector 15. The electric telescopic rod drives the transmission rod 19 to perform a short-distance reciprocating motion (if a fast reciprocating motion is required, the electric telescopic rod can be replaced with a cylinder, and the protective pipe 18 is used to protect the electric telescopic rod), and drives the connecting rod 17 and the cleaning brush 16 to move to clean the deflector 15.

[0036] Specifically, there is a 0.5 cm gap between the deflector 15 and the inner wall of the ash hopper 11. On both sides of the inner surface of the ash hopper 11, there are fixed connection of deflector substrates 20 that cooperate with the deflector 15. The deflector substrates 20 do not contact the deflector 15. By means of the deflector substrates 20, it is avoided that dust falls into the gap between the deflector 15 and the box body 1.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
