Technical Field

[0001] The present invention belongs to the technical field of dust collectors, and in particular relates to an electric bag composite dust collector. Background Art

[0002] The electrostatic bag composite dust collector is a new type of composite dust removal equipment based on two mature dust removal theories: electrostatic dust removal and bag dust removal. It combines the advantages of electrostatic dust removal and bag dust removal, with high dust removal efficiency and significantly better removal of fine particulate matter than traditional dust collectors.

[0003] During the use of the dust collector, the dust bag is prone to clogging, which reduces the dust removal efficiency of the dust collector. The electric bag composite dust collector currently on the market does not have the self-cleaning function of the dust bag. The dust bag of the dust collector often needs to be removed and cleaned, which is inconvenient to operate and has low cleaning efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] An electric bag composite dust collector includes a dust collector housing 1, an electrode plate 2, and a dust filter bag 3. The electrode plate 2 and the dust filter bag 3 are arranged in sequence in the dust collector housing 1. After the flue gas enters the electric bag composite dust collector, it first passes through the electrode plate 2 for dust removal, then passes through the dust filter bag 3 for dust removal, and is then discharged to the outside of the electric bag composite dust collector. The dust filter pore size of the dust filter bag 3 is small, and the dust filter bag 3 is easily clogged after long-term use, affecting the dust filtering efficiency of the dust collector. In order to facilitate the self-cleaning of the dust filter bag 3, a backflush part 4 and a filter bag cleaning component are provided in the electric bag composite dust collector. 5. The back-flushing component 4 is used to change the direction of airflow through the dust filter bag 3. That is, under normal conditions, the flow direction of air through the dust filter bag 3 is forward, and under the back-flushing state, the flow direction of air through the dust filter bag 3 is reverse, so that the airflow entering the dust collector flows through the back of the dust filter bag 3 to the front of the dust filter bag 3, thereby blowing away the dust attached to the outer end surface of the dust filter bag 3 under normal conditions, and realizing back-flushing cleaning of the dust filter bag 3. At the same time, the filter bag cleaning component 5 brushes the outside of the dust filter bag 3, thereby further cleaning the dust filter bag 3 and further ensuring the cleaning efficiency of the dust filter bag 3.

[0027] The back-blowing member 4 includes a back-blowing plate 4-3, a connecting column 4-4 and a windshield 4-2. The back-blowing plate 4-3 and the windshield 4-2 are connected in parallel to the connecting column 4-4. The back-blowing plate 4-3 is provided with a back-blowing slot 4-1, and the windshield 4-2 is provided with a ventilation slot 3-3. The back-blowing plate 4-3 and the windshield 4-2 are connected at the same time by the connecting column 4-4, so that the windshield 4-2 is linked to the back-blowing slot 4-1, that is, pulling and pulling the connecting column 4-4 can The back-blowing plate 4-3 and the wind shield 4-2 move simultaneously, and the back-blowing component 4 is slidably installed on the dust filter bag 3. When the back-blowing component 4 is pulled out, the back-blowing slot 4-1 opens, allowing the airflow to flow into the dust filter bag 3, thereby back-blowing the dust filter bag 3 to back-blow the dust filter bag 3 for dust removal. Under normal circumstances, the back-blowing component 4 is located in the dust filter bag 3. At this time, the back-blowing slot 4-1 is closed, and the airflow flows forward to the dust filter bag, and the dust in the airflow is filtered through the dust filter bag 3.

[0028] A flow plate 3-1 is provided in the dust filter bag 3, and a flow groove 3-2 is provided on the flow plate 3-1. The ventilation groove 3-3 is adapted to the flow groove 3-2, and the wind shield 4-2 is slidably connected to the flow plate 3-1, and the flow groove 3-2 is opened and closed by moving the wind shield 4-2; when the back-blowing component 4 is pulled out, the ventilation groove 3-3 and the flow groove 3-2 are staggered, and the gas in the electric bag composite dust collector is guided to the inside of the dust filter bag 3 through the wind shield 4-2, so that the airflow cannot flow out of the rear end of the dust filter bag 3, and the dust filter bag 3 is backblown. Under normal circumstances, the ventilation groove 3-3 and the flow groove 3-2 overlap, which facilitates the airflow to flow to the rear end of the dust filter bag 3 for discharge.

[0029] A limiter is provided on the connecting column 4-4, which is connected to the dust filter bag 3. The moving range of the back-blowing component 4 is limited by the limiter. The limiter includes a connecting rod 4-5 and a limiter head 4-6. The connecting rod 4-5 is connected to the connecting column 4-4, and the limiter head 4-6 is set toward the inner wall of the dust filter bag 3.

[0030] The dust filter bag 3 includes a filter bag unit 3-5 and a filter bag frame 3-4. The filter bag unit 3-5 is evenly connected to the filter bag frame 3-4. A backflush mounting groove is provided on the filter bag frame 3-4. The backflush member 4 is slidably installed in the backflush mounting groove. A limit groove 3-6 is provided on the inner wall of the filter bag frame 3-4. The limit member is adapted to the limit groove 3-6, and the limit head 4-6 is inserted into the limit groove 3-6.

[0031] A filter screen made of the same material as the dust bag 3 is provided in the back-blowing groove 4-1, and the end face of the back-blowing plate 4-3 is in contact with the side wall of one side of the back-blowing installation groove. When the back-blowing component 4 is reset to its initial state, the filter screen in the back-blowing groove 4-1 is scraped by the side wall of the back-blowing installation groove, thereby removing the dust on the filter screen of the back-blowing groove 4-1, thereby ensuring that the dust is absorbed at the front end of the dust bag 3 and preventing the dust from being discharged to the rear end of the dust bag 3.

[0032] In some preferred embodiments, a brush 3-7 is provided on the filter bag frame 3-4, and the brush cleans the filter screen in the backflush tank 4-1.

[0033] In some preferred embodiments, the filter bag unit 3-5 is a hard columnar structure, and a bracket connected to the filter bag frame 3-4 is provided inside the filter bag unit 3-5 to ensure the strength of the filter bag unit 3-5, thereby facilitating the filter bag cleaning assembly 5 to brush the outside of the filter bag unit 3-5.

[0034] The filter bag cleaning assembly 5 includes a cleaning head 5-1 and a driving member 5-2. The cleaning head 5-1 is mounted on the outside of the dust filter bag 3. The driving member 5-2 is connected to the cleaning head 5-1. The driving member 5-2 drives the cleaning head 5-1 to move, thereby enabling the cleaning head to remove dust from the outer wall of the dust filter bag 3. In some embodiments, the driving member 5-2 is arranged in the vacuum cleaner case 1.

[0035] In some embodiments, in order to ensure that the driving member 5-2 can stably drive the cleaning head 5-1 to move, the driving member 5-2 is arranged outside the vacuum cleaner case 1, and the driving member 5-2 includes a driving motor 5-4, a driving screw 5-5 and a screw slider 5-6. The driving motor 5-4 is installed outside the vacuum cleaner case 1, the driving screw 5-5 is connected to the driving motor 5-4, the screw slider 5-6 is installed on the driving screw 5-5, and the screw slider 5-6 extends into the vacuum cleaner case 1 and is connected to the cleaning head 5-1, so as to facilitate the driving of the cleaning head 5-1 to move by the driving motor 5-4.

[0036] The cleaning head 5-1 includes a cleaning unit frame 5-3, and a brush is connected to the inner wall of the cleaning unit frame 5-3. The brush is adapted to the dust filter bag 3, that is, the brush faces the filter bag unit 3-5, and the filter bag unit 3-5 is brushed by the brush, thereby further improving the cleaning effect of the filter bag unit 3-5.

[0037] A back-blowing member sensor 6 is installed on the vacuum cleaner housing 1, and the back-blowing member sensor 6 is connected to the driving member 5-2. The back-blowing member sensor 6 is set toward the back-blowing member 4 to detect the pulling position of the back-blowing member 4. When the back-blowing member 4 is pulled out and the back-blowing member 4 blocks the back-blowing member sensor 6, the back-blowing member sensor 6 sends a signal to the driving motor 5-4, and the driving motor 5-4 works to ensure that the filter bag cleaning component 5 works during the back-blowing process of the dust bag 3.

[0038] The vacuum cleaner case 1 is connected to a first dust collecting port 1-1 adapted to the electrode plate 2 and a second dust collecting port 1-2 adapted to the dust filter bag 3. A baffle 1-3 is provided on the first dust collecting port 1-1. During the backflushing process, the first dust collecting port 1-1 will be blocked by the baffle so that all dust is discharged through the second dust collecting port 1-2. An air pump 1-4 is provided on the second dust collecting port 1-2. During the backflushing process, the air pump 1-4 works to increase the gas flow rate in the dust collector, thereby further improving the cleaning effect of the filter bag unit 3-5.
