The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of a first embodiment of the present invention.
Fig. 2 is a schematic structural diagram of a second embodiment of the present invention.
In the figure: 1 is a first fan, 2 is a primary unit, 3 is a secondary unit, 4 is a second fan, 5 is a cyclone separator,
301 is an outer frame casing, 302 is a bag-type dust collector, 303 is an upper valve, 304 is a lower valve, 305 is a bag-type dust collector sealing cover, and 306 is a middle valve.
Detailed Description
The first implementation mode comprises the following steps:
as shown in fig. 1, the dust removing unit for dust and smoke dust of the present invention comprises a primary unit 2 and a secondary unit 3 connected with each other, wherein the secondary unit 3 comprises a plurality of bag-type dust removers 302 vertically arranged in an outer frame housing 301; the dust-containing air in the primary unit 2 is sent to a power device of a bag-type dust collector in the secondary unit 3, the inner sides of the upper end and the lower end of the bag-type dust collector 3 are respectively provided with an upper valve 303 and a lower valve 304, the lower end of the bag-type dust collector 302 is connected with a second fan 4 through a pipeline, and the second fan 4 is connected with the primary unit through a cyclone separator 5 to form circulation. In this embodiment, the power device adopts positive pressure to send dust-containing air into the secondary unit 3 from the primary unit 2, the power device is a first fan 1, one end of the first fan 1 is connected with the primary unit 2, and the other end of the first fan is communicated with the upper space of the bag-type dust collector 302 in the secondary unit 2.
The working principle is as follows:
in the embodiment, after the dust-containing air is cleaned by the primary unit 2 to remove larger dust particles, the dust-containing air is sent to the secondary unit by the first fan 1 of the power device of the primary unit 2. In the secondary unit, dust-containing air passes through the bag-type dust collector 302, dust is trapped inside the bag-type dust collector 302, after the dust-containing air passes through the bag-type dust collector 302 for a period of time, the upper valve 303 is closed, the lower valve 304 is opened, and the second fan 4 sucks away the dust, so that self-cleaning of the bag-type dust collector 302 is realized. After the bag-type dust collector 302 is cleaned, the lower valve 304 is closed, the upper valve 303 is opened, and the operation is continued. A plurality of combinations work simultaneously, so that the dust removal efficiency is improved, and the energy consumption is reduced. In a plurality of combinations, the bag-type dust collector 302 always keeps one combination clean to keep the pressure balance of the whole secondary unit 3 and avoid influencing the processing air volume of the whole unit. After the second fan 4 sends the air containing dust into the cyclone separator 5, the heavier dust falls into the bottom of the cyclone separator 5, and the air containing a small amount of lighter dust returns to the first-stage unit 2 from the top of the cyclone separator 5 and continues to circulate.
The second embodiment:
as shown in fig. 2, the remaining parts of the second embodiment are the same as those of the first embodiment, except that a power device sends dust-containing air from a primary unit to a secondary unit by using negative pressure, the power device is a first fan 1, a bag-type dust collector sealing cover 305 is fixed outside the bag-type dust collector 302, a middle valve 306 is arranged in the middle of the bag-type dust collector sealing cover 305, and the first fan 1 is connected with the middle valve 306. In the embodiment, the dust-containing air in the primary unit 2 is sucked into the bag-type dust collector 302 in a negative pressure mode, the upper valve 303 and the middle valve 306 are opened, the lower valve 304 is closed, and the first fan 1 is started to suck the dust-containing air into the bag-type dust collector 302; the upper valve 303 and the middle valve 306 are closed, the lower valve 304 is opened, and the second fan 4 is started to suck away the dust. Then, compared with the first embodiment, in the second embodiment, the dust escaping from the gap of the bag-type dust collector 302 is sucked away by the first fan 1 in a negative pressure manner, because the bag-type dust collector 302 is sealed by the bag-type dust collector sealing cover 305 in the present embodiment. Therefore, the dust is not easy to accumulate, the cleaning is better, and the dust explosion and the electrostatic explosion are effectively prevented; second embodiment the present invention is the best embodiment.
Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
