[0002] Bag dust collector is a dust collection method, which has gradually replaced electrostatic dust collector. Bag dust collectors are mostly used in cement mills, raw material mills, coal mills, dryers and kiln tails. The dust collection efficiency of bag dust collectors can reach more than 99%, and it is safer than electric dust collectors.

[0003] According to the patent of an anti-clogging kiln head bag dust collector with the authorization announcement number CN211585658U, the patent is a known prior art, and although the patent has the advantages of being able to collect dust filtered by the dust filter bag and being easy to use, the technical solution of the patent still has the following defects in actual use: when the patent uses vibration to clean the dust adhered to the surface of the dust filter bag, due to the small movement amplitude of the telescopic rod, the vibration intensity of the dust filter bag will be weak, that is, it is difficult to effectively shake off the dust on the surface of the dust filter bag, which can easily cause the dust filter bag to become clogged. For this reason, we propose an anti-clogging bag dust collector. Utility Model Content

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] See also Figure 2 and Figure 3 The utility model provides an anti-clogging bag dust collector, comprising a shell 1, a top cover 2 is fixedly installed on the top of the shell 1, the top of the top cover 2 is fixedly connected to the top of the shell 1 by bolts, an air inlet pipe 4 is fixedly connected to one side of the shell 1, a mounting plate 5 is fixedly connected to the bottom of the top cover 2, a dust filter bag 6 is fixedly connected to the bottom of the mounting plate 5, an air outlet pipe 7 is fixedly connected to one side of the dust filter bag 6, the air outlet pipe 7 is fixedly sleeved on the other side of the shell 1, and an air outlet valve is fixedly installed on the outside of the air outlet pipe 7;

[0021] In this embodiment, after the gas to be dust-removed is transported to the interior of the outer shell 1 by means of the air inlet pipe 4, the gas containing dust will gradually diffuse and permeate the entire inner cavity of the outer shell 1. At this time, the air outlet valve is opened to allow the dust gas to pass through the dust filter bag 6 under the action of air pressure. The dust filter bag 6 can be used to filter out the dust in the gas, so that the dust is adsorbed on the surface of the dust filter bag 6, and the filtered gas will be discharged along the air outlet pipe 7.

[0022] See also Figure 1 and Figure 2 An air compressor 8 is fixedly installed on the top of the top cover 2, one side of the air compressor 8 is fixedly connected to the other side of the dust filter bag 6 through a backflush pipe 9, a backflush valve is fixedly installed on the outside of the backflush pipe 9, and the backflush pipe 9 is a hose;

[0023] In this embodiment, when the dust on the surface of the dust filter bag 6 needs to be cleaned, the delivery of gas at the air inlet pipe 4 is stopped, the air outlet valve is closed, the back-blowing valve is opened, and the air compressor 8 is started. The air is compressed by the air compressor 8. At this time, the compressed air will flow into the interior of the dust filter bag 6 along the back-blowing pipe 9, and with the continuous input of high-pressure air, the air inside the dust filter bag 6 will diffuse outward and impact the dust on the surface of the dust filter bag 6, so as to facilitate the backblowing of the dust adhered to the surface of the dust filter bag 6, thereby avoiding the problem of clogging of the dust filter bag 6 due to dust accumulation, thereby improving the permeability of the dust filter bag 6.

[0024] See also Figure 1 and Figure 2 The bottom of the shell 1 is fixedly connected with a dust hopper 3, the bottom of the dust hopper 3 is fixedly connected with a supporting leg, and a discharge valve is fixedly installed on the outside of the bottom end of the dust hopper 3, and a striking assembly 10 is arranged below the dust filter bag 6, and the striking assembly 10 includes a driving shaft 101, and the driving shaft 101 is movably sleeved inside the shell 1, and one end of the driving shaft 101 is fixedly connected with a driving motor 102, and the outside of the driving shaft 101 is fixedly connected with a spring 103, and the outside of the driving motor 102 is fixedly sleeved with a protective cover, and the spring 103 is located below the dust filter bag 6;

[0025] In this embodiment, when the dust filter bag 6 is backblown for cleaning, the drive motor 102 is turned on to rotate the drive shaft 101, and the drive shaft 101 will drive the spring 103 to move, so that the dust filter bag 6 can be struck by utilizing the diversity of the movement directions of the spring 103, so that the dust adhered to the surface of the dust filter bag 6 can fall off quickly, thereby improving the cleaning effect of the dust on the surface of the dust filter bag 6. At the same time, the fallen dust will accumulate inside the dust hopper 3. If the discharge valve is opened, the dust inside the dust hopper 3 can be discharged.

[0026] The working principle and use process of the utility model are as follows: first, the air to be dusted is transported to the interior of the housing 1 by using the air inlet pipe 4, and the air containing dust will gradually diffuse and permeate the entire inner cavity of the housing 1. At this time, the air outlet valve is opened, so that the dust gas passes through the dust filter bag 6 under the action of air pressure, and the dust filter bag 6 can be used to filter out the dust in the gas, so that the dust is adsorbed on the surface of the dust filter bag 6, and the filtered gas will be discharged along the air outlet pipe 7;

[0027] Then, when the dust on the surface of the dust filter bag 6 needs to be cleaned, the delivery of gas at the air inlet pipe 4 is stopped, the air outlet valve is closed, the back-blowing valve is opened, and the air compressor 8 is started. The air is compressed by the air compressor 8. At this time, the compressed air will flow into the dust filter bag 6 along the back-blowing pipe 9. With the continuous input of high-pressure air, the air inside the dust filter bag 6 will diffuse outward and impact the dust on the surface of the dust filter bag 6, so as to blow back the dust adhering to the surface of the dust filter bag 6, thereby avoiding the problem of clogging of the dust filter bag 6 due to dust accumulation, thereby improving the permeability of the dust filter bag 6;

[0028] Finally, when the dust filter bag 6 is back-blown and cleaned, the drive motor 102 is turned on to rotate the drive shaft 101, and the drive shaft 101 will drive the spring 103 to move, so that the dust filter bag 6 can be hit by utilizing the diversity of the movement direction of the spring 103, so that the dust adhered to the surface of the dust filter bag 6 can fall off quickly, thereby improving the cleaning effect of the dust on the surface of the dust filter bag 6. At the same time, the fallen dust will accumulate inside the dust collecting hopper 3. If the discharge valve is opened, the dust inside the dust collecting hopper 3 can be discharged.
