Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a vertical flow channel dust removal device. Background Art

[0002] Fine dust is more harmful to the human body than coarse particles. Therefore, since the 1970s, many countries have focused on studying the control technology of fine dust (commonly called microparticles) and proposed many corresponding technical measures.

[0003] The dust removal device inside the distribution cabinet refers to an integrated gas-solid separation device specifically used to remove suspended dust in the confined space of electrical equipment. It actively separates particulate matter in the air through physical interception (such as filters), electrostatic adsorption or centrifugal sedimentation mechanisms to prevent the deposition of conductive dust that may cause poor electrical contact or heat dissipation failures. Its core function is to maintain the cleanliness of the cabinet to ensure the safe operation of the power system.

[0004] In the prior art, due to the design of the air flow channel, dust accumulated in the dust box is often repeatedly blown up during air circulation and blown out from the air outlet again, so that the dust removal effect of the dust-laden air does not meet user needs. Utility Model Content

[0005] The utility model provides a vertical flow channel dust removal device, which sets a dust collecting mechanism at the vertical flow channel in the air duct. When the air circulates, after entering the inner flow box and the bellows, it cannot flow out directly from the other side of the air duct, but first hits the layer plate, so that the larger dust particles in the dust-laden gas flow along the inclined surface of the bellows into the fine dust collecting interlayer, and finally fall into the dust collecting box, preventing the air from blowing up the dust again, thereby solving the problems raised in the above-mentioned background technology, namely:

[0006] In the prior art, due to the design of the air flow channel, dust accumulated in the dust box is often repeatedly blown up during air circulation and blown out from the air outlet again, so that the dust removal effect of the dust-laden air does not meet user needs.

[0007] To achieve the above purpose, the dust removal device includes a box body, one side of which is provided with an air inlet and an air outlet from bottom to top, and the air inlet and the air outlet are connected through an air duct inside the box body; a dust collecting mechanism is provided at the vertical flow channel of the air duct;

[0008] The dust collecting mechanism includes an inner flow box embedded in the vertical flow channel, and a bellows with an upward opening is fixedly mounted above the inner flow box;

[0009] The air duct is provided with a horizontal isolation layer plate above the wind box;

[0010] Conical tubes are symmetrically distributed on both sides of the layer plate with the axis of the wind box opening as the reference, and are used to redirect the treated gas into the air duct;

[0011] A dust collecting layer is formed between the outer wall of the inner flow box and the inner wall of the air duct.

[0012] In the above technical solution, during use, the dust-laden gas enters the air duct from the air inlet, flows into the inner flow box at the vertical flow channel of the air duct, and is finally blown out from the bellows above the inner flow box. The blown dust-laden gas is blocked by the layer plate and cannot flow directly into the air duct on the other side. Instead, after hitting the layer plate, the larger particles bounce off the bottom of the dust box, causing the dust to fall along the inclined surface of the outer side of the bellows, and then pass through the dust collecting layer formed between the inner flow box and the bellows, and fall into the dust collecting box, completing the collection of dust. At the same time, the symmetrical distribution characteristics of the conical tube avoid the formation of unilateral airflow vortexes, so that the purified gas flows back to the air duct smoothly, and in the process of air reflux, because the lateral distance of the dust collecting layer is small, the internal wind force tends to be stable, and a large air volume cannot be formed to carry out the dust inside the dust collecting box.

[0013] On this basis, the inclination angle of the side of the bellows is 30°-60°; the dust collecting interlayer is a cavity formed between the inner flow box and the air duct, and the dust collecting interlayer is U-shaped; the layer covers the entire cross-section of the air duct, and its edge is sealed with the inner wall of the air duct. The U-shaped distribution of the dust collecting interlayer allows the dust that falls after the dust-laden gas hits it to fall into the dust collecting box along the dust collecting interlayer.

[0014] In another technical solution, the air duct is provided with an impeller in the cavity above the layer plate, and the impeller is coaxially connected to the output shaft of the motor; the air duct is provided with a detachable filter near the air inlet, and the impeller rotates through the motor to make the dust-laden gas flow in from the air inlet, and after being processed by the internal dust collection mechanism, it flows out from the air outlet, so that the device can circulate and filter the dust-laden gas in the switch cabinet and the distribution cabinet during operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By setting up a dust collection mechanism at the vertical flow channel in the air duct, when the air circulates, after entering the inner flow box and the bellows, it cannot flow out directly from the other side of the air duct, but first hits the layer plate, so that the larger dust particles in the dust-laden gas flow into the fine dust collecting interlayer along the inclined surface of the bellows, and finally fall into the dust collecting box, preventing the air from blowing up the dust again, and effectively solving the key defect of the traditional dust removal of the distribution box cabinet that the dust in the dust collecting box is raised again due to airflow disturbance.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] At present, due to the design of the air flow channel in the existing technology, the dust accumulated in the dust collection box is often blown up repeatedly during air circulation and blown out from the air outlet again, so that the dust removal effect of the dust-laden air does not meet the user's needs. The utility model provides a vertical flow channel dust removal device, see Figure 3-Figure 5 As shown, it includes a box body 100, and an air inlet 101 and an air outlet 102 are provided on one side of the box body 100 from bottom to top. The air inlet 101 and the air outlet 102 are connected through an air duct 104 inside the box body 100; a dust collecting mechanism 200 is provided at the vertical flow channel of the air duct 104;

[0027] The dust collecting mechanism 200 includes an inner flow box 201 embedded in the vertical flow channel, and a wind box 202 with an upward opening is fixedly mounted above the inner flow box 201;

[0028] The air duct 104 is provided with a transverse isolation layer 204 above the air box 202;

[0029] On both sides of the layer plate 204, tapered tubes 205 are symmetrically distributed with respect to the opening axis of the wind box 202, for redirecting the processed gas into the air duct 104;

[0030] A dust collecting interlayer 203 is formed between the outer wall of the inner flow box 201 and the inner wall of the air duct 104 .

[0031] During use, dust-laden gas enters the vertical section of the air duct 104 from the air inlet 101, first flows through the inner flow box 201 and rises to the wind box 202. The high-speed airflow, carrying dust, strikes the layer plate 204 that completely covers the cross section of the air duct 104, forcing it to turn. Large dust particles gain a reverse force due to inertia, sliding along the inclined side wall of the wind box 202 into the U-shaped dust collecting interlayer 203 on its periphery.

[0032] Since the narrow passage of the dust collecting interlayer 203 blocks the main airflow disturbance, the dust falls directly into the dust collecting box 107 at the bottom of the dust collecting interlayer 203 by gravity in a static environment. At the same time, the symmetrical setting of the conical tube 205 can keep the airflows at two locations in a stable state when the gas refluxes, avoiding the airflow vortex caused by the unilateral setting of the conical tube 205. The purified gas is smoothly guided back to the air duct 104 through the conical tube 205, completely eliminating the problem of dust accumulated in the dust collecting box being blown up by the airflow for the second time in the traditional design.

[0033] See also Figure 3 As shown, the inclination angle of the side of the bellows 202 is 30°-60°; the dust collecting interlayer 203 is a cavity formed between the inner flow box 201 and the air duct 104, and the dust collecting interlayer 203 is U-shaped; the layer plate 204 covers the entire cross-section of the air duct 104, and its edge is sealed with the inner wall of the air duct 104. When the dust-laden airflow rushes out of the bellows 202 and hits the layer plate 204, it encounters resistance when contacting the layer plate 204, and thus bounces downward. After contacting the surface of the bellows 202, it rebounds again and flows back into the air duct 104 through the tapered tube 205.

[0034] Figure 1-Figure 2 In the figure, the air duct 104 is provided with an impeller 106 in the cavity above the layer plate 204, and the impeller 106 is coaxially connected to the output shaft of the motor 105; the air duct 104 is provided with a detachable filter 103 near the air inlet 101, and the impeller 106 rotates through the motor 105 to make the dust-laden gas flow in from the air inlet 101, and after being processed by the internal dust collecting mechanism 200, it flows out from the air outlet 102, so that the device can circulate and filter the dust-laden gas in the switch cabinet and the distribution cabinet during operation.

[0035] Working principle: Dust-laden air enters the vertical section of the air duct 104 from the air inlet 101, rises through the inner flow box 201, and is ejected from the wind box 202. It is blocked and deflected by the layer plate 204 that completely covers the cross section of the air duct 104.

[0036] The large dust particles in the air flow hit the layer plate 204 due to inertia and obtain a reverse force, sliding along the side wall of the wind box 202 into the U-shaped dust collecting interlayer 203;

[0037] Since the narrow channel of the dust collecting interlayer 203 isolates the main airflow disturbance, the dust falls directly into the bottom dust collecting box 107 by gravity in a static environment, while the purified gas is smoothly guided back to the air duct 104 through the conical tubes 205 symmetrical on both sides of the layer 204, and finally discharged from the air outlet 102.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
