[0028] The following will describe in detail some embodiments of the present utility model in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0029] As Figures 1 to 4 shown, an automatic separation dust suction device includes: a separation tower 300, a dust collection box 200, and a negative pressure mechanism 100. The negative pressure mechanism 100 is connected to the upper part of the dust collection box 200 through a first negative pressure pipeline 410. The middle part of the dust collection box 200 is connected to the upper part of the separation tower 300 through a second negative pressure pipeline 420. A dust blocking part 310 is arranged in the inner cavity of the separation tower 300. The separation tower 300 is also provided with a feed pipe 320. The discharge port of the feed pipe 320 is arranged below the dust blocking part 310. A recovery box 330 is arranged at the lower part of the separation tower 300. The feed port of the feed pipe 320 is connected to a third negative pressure pipeline 430, and the third negative pressure pipeline 430 is used for absorbing pollutants.

[0030] The negative pressure mechanism 100 generates negative pressure, and negative pressure is also generated in the dust collection box 200 through the first negative pressure pipeline 410. The dust collection box 200 is connected to the separation tower 300 through the second negative pressure pipeline 420, so negative pressure is also generated in the separation tower 300. The separation tower 300 is connected to the third negative pressure pipeline 430 through the feed pipe 320, so negative pressure is generated in the third negative pressure pipeline 430.

[0031] The third negative pressure pipeline 430 is used for absorbing pollutants. There are many types of pollutants. Typical pollutants are waste gases mixed with various types of dust particles, or may also include filter materials such as activated carbon that have adsorbed waste gases and dust particles.

[0032] The second negative pressure pipeline 420 is connected to the upper part of the separation tower 300, so that a negative pressure suction force is generated in the upper part of the separation tower 300. When the pollutants enter the interior of the separation tower 300 through the feed pipe 320, they are subjected to an upward suction force. The dust blocking part 310 is arranged above the feed pipe 320. When the pollutants are subjected to an upward suction force, the heavier substances in the pollutants, such as filter materials like activated carbon or larger dust particles, either directly fall into the lower recovery box 330 under their own weight without being affected by the upward suction force, or stay inside the separation tower 300 or fall into the lower recovery box 330 after being blocked by the dust blocking part 310. The lighter substances in the pollutants, such as small dust particles, are sucked into the upper part of the separation tower 300 under the action of negative pressure, enter the second negative pressure pipeline 420, and then enter the dust collection box 200.

[0033] In an optional embodiment, a funnel can be arranged at the upper part of the recovery box 330 to make it more convenient to concentrate large particles and improve the recovery efficiency.

[0034] In an alternative embodiment, the recycling bin 330 can be designed to be detachable. After the recycling bin 330 is detached from the separation tower 300, the pollutants in the recycling bin 330 can be further recycled. A sealing strip can be used between the recycling bin 330 and the separation tower 300 to enhance the sealing effect at the connection, ensure the negative pressure inside the separation tower 300, and prevent air leakage at the connection of the separation tower 300, which may cause insufficient suction.

[0035] The third negative pressure pipeline 430 can be a flexible hose, facilitating construction workers to connect the third negative pressure pipeline 430 to the construction site where pollutants are generated, thus making it easier to arrange the automatic dust separation and suction device at the construction site and improving the operation efficiency.

[0036] In an alternative embodiment, the cross-section of the inner cavity of the separation tower 300 is circular. With this shape of the separation tower 300, the negative pressure effect in the inner cavity of the separation tower 300 is better, the suction distribution is more uniform, dead corners are not easily generated, and dust accumulation in the inner cavity of the separation tower 300 can be avoided. Moreover, when large particles or filter materials are sucked into the inner cavity of the separation tower 300 under negative pressure, the contact effect between the large particles or filter materials and the inner wall of the separation tower 300 is better. Even if the large particles or filter materials impact the inner wall of the separation tower 300, the impact effect will be lower, making the separation tower 300 more durable.

[0037] In an alternative embodiment, the extension line of the axis of the feed pipe 320 is offset from the geometric center of the inner cavity of the separation tower 300. At this time, when the waste gas is sucked into the separation tower 300, it will not be directly sucked to the center of the separation tower 300. The waste gas, including the filter materials and dust particles therein, is more evenly distributed and more dispersed in the separation tower 300, which is more conducive to the dust blocking part 310 to block the dust particles in the waste gas, thereby improving the separation effect of the separation tower 300 on dust particles of different sizes.

[0038] In an alternative embodiment, the air flow direction of the feed pipe 320 is tangent to the inner wall of the separation tower 300. A specific setting form can be referred to Figure 2 , the feed pipe 320 and the separation tower 300 are arranged in an approximately tangent manner as a whole. However, due to problems such as wall thickness of the feed pipe 320 and the separation tower 300, the feed pipe 320 and the separation tower 300 cannot form an exact tangent. It is only necessary to make the air flow direction of the feed pipe 320 tangent to the inner wall of the separation tower 300. At this time, the waste gas, including the filter materials and dust particles therein, can be maximally dispersed in the separation tower 300, and the dust blocking part 310 can achieve the best blocking effect on the dust particles in the waste gas, improving the separation effect of the separation tower 300 on dust particles of different sizes.

[0039] The form of the feed pipe 320 is not limited to a straight pipe, and it may also be in the form of a curved pipe, a bent pipe, etc. As long as the exhaust gas tangentially contacts the inner wall of the separation tower 300 when entering the separation tower 300 through the feed pipe 320 under the action of negative pressure, the effect of dispersing the exhaust gas including the filter material and dust particles therein in the separation tower 300 can be achieved.

[0040] In an alternative embodiment, the dust blocking portion 310 extends from the inner wall of the separation tower 300 towards the center. The negative pressure suction in the center of the separation tower 300 is stronger. Small dust particles can naturally move from the outside of the inner cavity of the separation tower 300 towards the center under the action of the negative pressure suction, ensuring the dust suction efficiency of the entire automatic dust separation and suction device.

[0041] In an alternative embodiment, the dust blocking portion 310 has at least two layers. The multi-layer dust blocking portion 310 can ensure the dust blocking effect. In particular, the multi-layer dust blocking portion 310 can be arranged staggeredly. Among the small dust particles that can be sucked up by negative pressure, the heavier dust particles can also be intercepted by the dust blocking portion 310 under the blockage of the multi-layer dust blocking portion 310, thereby further separating the dust particles in the exhaust gas and only allowing small dust particles to enter the next dust collection box 200.

[0042] In an alternative embodiment, the dust blocking portion 310 is a spiral structure. The spiral dust blocking portion 310 forms at least two-layer structure, which is easy to form a multi-layer structure. The multi-layer spiral dust blocking portion 310 can naturally generate a spiral air flow in the upper part of the separation tower 300, thereby further enhancing the dust separation effect. Only small dust particles can enter the second negative pressure pipe 420 along with the spiral air flow. Larger dust particles will fall under the influence of their own weight during the upward movement along with the spiral air flow.

[0043] In an alternative embodiment, a filter cloth bag 210 is provided at the upper part of the dust collection box 200, a backflush pipe 220 is provided above the filter cloth bag 210, and a discharging mechanism 230 is provided at the lower part of the dust collection box 200.

[0044] When small dust enters the dust collection box 200, most of the dust particles will fall into the discharging mechanism 230 below under the action of their own weight, and a small part of the dust particles will gather on the filter cloth bag 210 under the action of negative pressure. The backflush pipe 220 can impact the filter cloth bag 210 in the reverse direction at a set frequency or timing, having an impact effect on the dust particles on the filter cloth bag 210, causing them to fall from the filter cloth bag 210 and enter the discharging mechanism 230. The dust particles in the dust collection box 200 are small dust particles. An ordinary open box cannot achieve a good effect of collecting these small dust particles. The discharging mechanism 230 processes the dust particles, such as by extrusion, so that the small dust particles can also be collected better for the next step of processing, such as dumping them outside the automatic dust separation and suction device, etc.

[0045] When the recoil pipe 220 causes the dust particles to fall off the filter cloth bag 210, it can also keep the filter cloth bag 210 in a better air-permeable state all the time, ensuring the negative pressure adsorption effect of the entire automatic separation dust suction device.

[0046] The material of the filter cloth bag 210 is not limited to cloth, but also includes other materials that can not only achieve the air-permeable effect but also the effect of intercepting or adsorbing dust particles.

[0047] When the filter cloth bag 210 is fixed in the dust collection box 200, other brackets can be used for auxiliary fixation, such as setting a multi-layer keel structure, etc., so that the filter cloth bag 210 is more evenly stressed, and to avoid deformation or damage of the filter cloth bag 210 under the negative pressure of the negative pressure mechanism 100.

[0048] In an alternative embodiment, the filter cloth bag 210 can be set to multiple layers. The multiple-layer filter cloth bags 210 can have different filtration pore sizes, and the filtration pore sizes of the filter cloth bag 210 gradually increase from top to bottom to achieve a multi-layer filtration effect, or the multiple-layer filter cloth bags 210 can have the same filtration pore size to intercept and adsorb dust particles layer by layer.

[0049] When the recoil pipe 220 impacts the filter cloth bag 210 in the reverse direction, the negative pressure mechanism 100 can be paused to enhance the reverse impact effect, making the dust particles on the filter cloth bag 210 easier to fall. The negative pressure mechanism 100 can also continue to work. When the recoil pipe 220 makes a reverse impact, the recoil pipe 220 can offset a part of the negative pressure generated by the negative pressure mechanism 100, and combined with the self-weight of the dust particles, it can also make the dust particles easier to fall from the filter cloth bag 210.

[0050] In an alternative embodiment, the pressure of the recoil pipe 220 is greater than the pressure generated by the negative pressure mechanism 100 at the upper part of the dust collection box 200. At this time, the recoil pipe 220 can achieve a better impact effect, making the dust particles on the filter cloth bag 210 easier to fall.

[0051] In an alternative embodiment, the discharging mechanism 230 includes an intermittent wheel feeder. The intermittent wheel feeder can achieve continuous feeding, continuously extruding and discharging small dust particles, which is more conducive to the subsequent treatment of small dust particles. A sealing connection can be adopted between the intermittent wheel feeder and the dust collection box 200, such as setting a sealing ring, etc., to ensure the sealing between the two and ensure the negative pressure effect of the entire automatic separation dust suction device.

[0052] The automatic separation and dust suction device provided by the present utility model only needs to align the third negative pressure pipeline 430 with the pollutants. Under the action of negative pressure, the pollutants enter the separation tower 300. The separation tower 300 can preliminarily separate the pollutants. The filter material and large dust particles are intercepted by the dust blocking part 310 and fall into the recycling box 330 below. The small dust particles enter the dust collecting box 200 through the second negative pressure pipeline 420 for recycling. Thus, the effect of efficient pollutant cleaning and recycling can be achieved, and the dust particles and the filter material can be recycled separately, which is convenient for subsequent separation treatment.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model.
