[0002] A dust separator is a process equipment used in industrial activities to separate solid particle dust from gas flow to purify the gas. At present, dust separators mainly use filter elements. When the gas passes through the filter element, the solid particle dust is filtered. However, the existing dust separator has a single air intake method and the air intake direction of the airflow is fixed. Therefore, it is easy for impurities to accumulate seriously on the end face of the filter element facing the air intake direction, thereby affecting the separation efficiency of gas and dust.

[0041] like Figure 1-4 As shown, the utility model discloses a gas dust separator, comprising:

[0042] The body 10 has a dust chamber;

[0043] The filter element 11 is installed in the body 10 and divides the dust chamber into an air inlet chamber 11a and an air outlet chamber 11b;

[0044] The exhaust port 12 is installed above the body 10 and connected to the exhaust cavity 11b;

[0045] The sewage outlet 13 is installed below the body 10 and communicates with the air inlet cavity 11a;

[0046] In this embodiment, an exhaust fan 12 a is installed at the exhaust port 12 , and a control valve 13 a is installed at the sewage outlet 13 .

[0047] In this embodiment, an air intake mechanism is also provided to control the airflow into the air intake cavity 11a, and the air intake mechanism includes a plurality of air intake nozzles 2 and a driving structure installed on the body and used to control the rotation of the air intake nozzles 2;

[0048] The air inlet nozzle 2 is rotatably disposed on the body 10 via a rotating shaft 20 , and can be controlled by a driving structure to rotate based on the rotating shaft and switch the air inlet direction of the air inlet nozzle 2 .

[0049] In this embodiment, the inner wall of the body is recessed with a groove 21 , the air inlet nozzle is rotatably connected in the groove 21 via a rotating shaft 20 , and the air inlet nozzle 2 is connected to an external pipe 22 .

[0050] In this embodiment, the driving structure includes:

[0051] The annular groove 30 is concavely disposed on the cavity wall of the air inlet cavity 11a;

[0052] The driven gear 31 is connected to the rotating shaft 20 and is located in the annular groove 30. The rotating shaft 20 extends from the groove 21 to the annular groove 30.

[0053] The driven gear ring 32 is disposed in the annular groove 30 through a supporting structure, and the outer ring of the driven gear ring 32 is meshed with the driven gear 31;

[0054] The driving gear 33 is driven by the motor 34 and meshes with the inner ring of the driven gear ring 32 .

[0055] In this embodiment, the support structure includes:

[0056] The support shaft 40 is installed in the annular groove 30;

[0057] Support gaskets 41 are arranged on the support shaft 40 at intervals;

[0058] The driven gear ring 32 is provided with a limiting groove 42 for the support shaft 40 to move. The limiting groove 42 extends circumferentially. The support shaft 40 passes through the limiting groove 42 and each support gasket 41 is located above the driven gear ring 32 and below the driven gear ring 32 respectively.

[0059] In this embodiment, there are three limiting grooves 42 , which are circumferentially equidistantly distributed on the driven gear ring.

[0060] refer to Figure 1-4 , the principle of this embodiment is:

[0061] When in use, the exhaust fan is started (at the same time, the external pipe sends the dust gas into the air inlet chamber through the air pump). When the control valve of the sewage outlet is closed, the air flow is filtered by the filter element and discharged from the exhaust port, completing the separation of gas and solid particles.

[0062] In the air intake process of this embodiment, the motor controls the driven gear ring to rotate clockwise or counterclockwise through the driving gear, and uses the driven gear ring to control the rotation of the driven gear, and uses the rotating shaft to control the air intake nozzle to swing based on the rotating shaft, and adjusts the jet direction of the air intake nozzle to distribute the dust gas in the air intake cavity, so that the airflow can be filtered by various positions of the filter element and discharged from the exhaust port, thereby improving the filtration efficiency.

[0063] After the dust gas treatment is completed, open the control valve at the sewage outlet and discharge the solid particle impurities in the air inlet cavity uniformly.

[0064] Embodiment 2 is different from Embodiment 1 in that:

[0065] like Figure 5 As shown, in this embodiment, the air inlet nozzle 2 includes:

[0066] The nozzle body 50 is rotatably connected to the main body via the rotating shaft 20 and has a jet chamber 51;

[0067] A splitter head mounted on the exhaust end of the nozzle body 50;

[0068] The splitter head has a plurality of dispersion chambers 52 connected to the jet chamber 51 .

[0069] In this embodiment: the diverter head includes:

[0070] The sliding shaft 60 is sleeved on the nozzle body 50 and is axially slidable relative to the nozzle body 50, and is provided with a chamber 61 that penetrates axially;

[0071] The flow dividing portion 62 has the dispersion chamber 52 and is mounted on the sliding shaft 60;

[0072] A drain groove 63 is formed on the sliding shaft 60 and extends radially and communicates with the chamber 61;

[0073] The compression spring 64 is sleeved on the nozzle body 50 and connected to the sliding shaft 60 .

[0074] refer to Figure 5The principle of this embodiment is that when the air inlet nozzle delivers the dust gas into the air inlet chamber, the dust gas enters the dispersion chamber through the jet chamber, thereby dispersing the dust gas to better diffuse the dust gas and improve the filtration efficiency. At the same time, in order to avoid clogging of the air inlet nozzle, when the dispersion chamber is blocked (such as when solid particles accumulate in the dispersion chamber), during the continuous air intake of the jet chamber, the air pressure in the chamber of the sliding shaft gradually increases, causing the sliding shaft to overcome the compression spring and move to the side away from the nozzle body until the drain groove is connected to the chamber of the sliding shaft, so that the solid particles blocked in the chamber position are discharged from the drain groove, thereby avoiding clogging of the dispersion chamber position of the air inlet nozzle.

[0075] It is worth noting that: in this embodiment, the upward inclined setting of the dispersion chamber can make the ejected gas flow to the upper area of ​​the air inlet chamber, and can be quickly discharged from the exhaust port after being filtered by the filter element, and the different inclination angles of the dispersion chamber can disperse the dust gas to different positions of the air inlet chamber; not only that, the inclined dispersion chamber can make the solid particles blocked inside it slide toward the direction of the sewage trough when the sewage trough is opened, and thus be discharged from the sewage trough.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
