Description

Technical Field

[0001] The utility model relates to the field of dust removal equipment, and more specifically, it relates to a pulse bag filter dust collector. Background Art

[0002] A pulse bag filter dust collector is an efficient industrial dust removal equipment. The dust-containing gas rises with the air flow and enters the bag chamber. After being filtered by the filter bags, the dust particles are retained on the outer side of the filter bags. The purified gas enters the upper box body from the inside of the filter bags and then exits from the air outlet. When the dust on the surface of the filter bags continuously increases and causes the resistance of the equipment to rise to the set value, the dust cleaning controller issues a dust cleaning command, and compressed air is sprayed into the filter bags through the pulse valves, causing the filter bags to suddenly expand. Under the action of the reverse air flow, the dust attached to the surface of the filter bags quickly detaches from the filter bags and falls into the ash hopper, so as to achieve the purpose of dust cleaning.

[0003] The dust in the ash hopper needs to be cleaned. Since the dust-containing gas will pass through the ash hopper, the air inlet needs to be stopped during the cleaning process, so that the dust collector cannot continue to operate during the cleaning process, thus affecting the working efficiency of the dust collector.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a pulse bag filter dust collector.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A pulse bag filter dust collector includes a dust collector main body. An air inlet is provided on the side wall of the dust collector main body. A bag chamber and an ash hopper chamber are arranged inside the dust collector. The air inlet is communicated with the bag chamber through a diversion channel. Only one communication port communicating with the ash hopper chamber is provided on the inner bottom wall of the bag chamber. A closing plate for closing the communication port is provided on the dust collector main body.

[0007] The utility model is further provided as follows: A plurality of filter bags are arranged inside the bag chamber. One end of the diversion channel communicating with the bag chamber is located below the filter bags.

[0008] The utility model is further provided as follows: The diversion channel is in an inclined state. One end of the diversion channel communicating with the air inlet is higher than one end communicating with the bag chamber.

[0009] The utility model is further provided as follows: One end of the diversion channel communicating with the bag chamber is higher than the inner bottom wall of the bag chamber.

[0010] The utility model is further provided as follows: An electric push rod is fixedly connected inside the dust collector main body. The output end of the electric push rod is fixedly connected with the closing plate. The electric push rod is used to drive the closing plate to close or open the communication port.

[0011] The utility model is further configured such that: a pulse valve is further provided inside the dust collector main body, and the pulse valve is used to blow compressed air into the filter bag.

[0012] In summary, the utility model has the following beneficial effects: when people need to discharge the dust in the hopper chamber, people can close the communication port by using a closing plate. Such a setting makes the dust-containing gas not enter the hopper chamber, so that during the dust cleaning process, the dust collector main body can still operate, thereby improving the working efficiency of the dust collector.

[0016] The following combines the drawings and embodiments to describe the utility model in detail.

[0017] A pulse jet bag filter, as Figure 1 and Figure 2As shown in the figure, it includes a dust collector main body. An air inlet 1 and an air outlet are provided on the side wall of the dust collector main body. A bag chamber 2 and an ash hopper chamber 3 are arranged inside the dust collector. The air inlet 1 is communicated with the bag chamber 2 through a diversion channel 4. Only one communication port communicating with the ash hopper chamber 3 is provided on the inner bottom wall of the bag chamber 2. A closing plate 5 is provided on the dust collector main body for closing the communication port. A number of filter bags 6 are arranged in the bag chamber 2. The dusty gas enters the diversion channel 4 through the air inlet 1 and directly enters the bag chamber 2 through the diversion channel 4. After passing through the filter bags 6 on the bag chamber 2, the dusty gas is purified, and the purified gas is discharged from the air outlet. When people need to discharge the dust in the ash hopper chamber 3, people can close the communication port by using the closing plate 5. Such a setting makes the dusty gas not enter the ash hopper chamber 3, so that during the dust cleaning process, the dust collector main body can still operate, thereby improving the working efficiency of the dust collector. The inner bottom wall of the bag chamber 2 is located on the closing plate 5, so that when the amount of dust accumulated on the inner bottom wall of the bag chamber 2 is relatively large, people can open the closing plate 5 to open the communication port. At this time, the dust in the bag chamber 2 will enter the ash hopper chamber 3 through the communication port under the action of gravity. After the dust floats out of the bag chamber 2, the communication port is closed again. Such a setting can ensure that the amount of dust in the bag chamber 2 always remains in a relatively small state, so that the dusty gas passing through the bag chamber 2 is not likely to stir up dust. The end of the diversion channel 4 communicating with the bag chamber 2 is located below the filter bags 6. Such a setting makes the dusty gas come into contact with the outer walls of each filter bag 6 after entering the bag chamber 2.

[0018] As Figure 2 shown, the diversion channel 4 is in an inclined state. The end of the diversion channel 4 communicating with the air inlet 1 is higher than the end communicating with the bag chamber 2. Such a setting makes the dust with larger particles in the dusty gas enter the bag chamber 2 along the diversion channel 4, so that after the closing plate 5 is opened, the dust can fall into the ash hopper chamber 3. The end of the diversion channel 4 communicating with the bag chamber 2 is higher than the inner bottom wall of the bag chamber 2. Since the dusty gas blows directly away from the inner bottom wall of the bag chamber 2 after entering the bag chamber 2, such a setting makes the dust on the inner bottom surface of the bag chamber 2 still have a certain distance from the diversion channel 4, so that in the case of less dust, the dusty gas is not likely to stir up dust after entering the bag chamber 2. An electric push rod 7 is fixedly connected inside the dust collector main body. The output end of the electric push rod 7 is fixedly connected with the closing plate 5. The electric push rod 7 is used to drive the closing plate 5 to close or open the communication port. Using the electric push rod 7 to drive makes the movement of the closing plate 5 relatively stable, ensuring that the closing plate 5 can fit with the communication port of the bag chamber 2. A pulse valve 8 is also arranged inside the dust collector main body. The pulse valve 8 is used to blow compressed air into the filter bags 6. The compressed air blows through the bag chamber 2 from top to bottom and then discharges from the air inlet 1 along the diversion channel 4. The pulse valve 8 can backwash the filter bags 6 to ensure the filtering effect of the filter bags 6. During the backwashing process of the filter bags 6, people can directly open the closing plate 5, so that the dust directly falls from the bag chamber 2 into the ash hopper chamber 3 under the action of the compressed air.

[0019] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
