Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of environmental protection, and particularly relates to a smoke exhaust device. BACKGROUND
[0002] When a structure black part is subjected to shot blasting in a painting workshop, dust-containing gas generated by shot blasting is filtered and then discharged into the atmosphere through a chimney. However, although the shot blaster of a common manufacturer now generally has a dust removal device, so that the dust-containing gas is filtered through multiple stages to meet the corresponding standard (for example, even <10 mg / m3), the chimney discharge port is generally higher than the roof of the workshop and adopts a direct discharge mode. Thus, after a long period of production, a small amount of dust will continuously settle on the roof of the workshop and the surrounding workshops due to gravity after being discharged through the chimney. After a long period of production, the iron-containing particles accumulated on the roof of the workshop near the chimney will cause large-area rusting of the roof of the workshop; the iron-containing particles falling to the workshop for a long time will also affect the physical and mental health of the personnel in the workshop.

[0033] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the application, and are not intended to limit the application.
[0034] The application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.
[0035] Referring to FIG. 1, Figure 1 The present embodiment provides a smoke exhaust device, which can be used in a smoke exhaust treatment system in a shot blasting process. Of course, it is also applicable to dust exhaust treatment in other polishing processes.
[0036] The shot blasting is usually to hit the rusted parts by the steel shot through the motor drive at high speed to remove the rust and oxide skin on the surface of the parts. It can be understood that the dust-containing gas in the shot blasting machine after the shot blasting is discharged into the atmosphere through the pipeline under the action of the fan and after different degrees of filtration.
[0037] It should be noted that although the shot blasting machine of the general manufacturer now has a dust removal device, the dust-containing gas is filtered through multiple stages to meet the corresponding standard (such as even <10 mg / m3), but the chimney discharge port is generally higher than the roof of the factory building. After a long time of production, the trace dust discharged through the chimney will continuously settle on the roof of the factory building and the surrounding workshops due to gravity. After a long time of production, the iron-containing particles accumulated on the roof of the factory building near the chimney will cause large-area rusting of the roof of the factory building; the iron-containing particles falling to the workshop for a long time will also affect the physical and mental health of the personnel in the workshop.
[0038] Please refer to Figure 1 and Figure 2 To solve the above problems, the smoke exhaust device provided by the embodiment includes a chimney body 100, a flow guide assembly 200, and a collection assembly 300. The top of the chimney body 100 is provided with a smoke exhaust port 110, wherein the smoke exhaust port 110 of the chimney body 100 is usually arranged vertically upward.
[0039] The flow guide assembly 200 includes a flow guide body 220 and a flow guide cover 210. The flow guide cover 210 is arranged above the smoke exhaust port 110 and forms a relatively closed chamber, and one end of the flow guide cover 210 towards the chimney body 100 is formed with a flow guide outlet 210a. The flow guide body 220 is arranged on the outer circumferential surface of the chimney body 100 and connected with the flow guide cover 210, and the flow guide body 220 and the outer wall of the chimney body 100 form a flow guide cavity 220a which is communicated with the flow guide outlet 210a.
[0040] Further, the bottom of the flow guide body 220 is provided with an ash collecting port 224 for timely discharging the settled particles and dust to prevent accumulation. The wall of the flow guide body 220 is provided with a plurality of apertures 223 for facilitating the discharge of the flue gas flow to ensure smooth exhaust.
[0041] The collection assembly 300 is arranged below the ash collecting port 224 for collecting the settled particles and dust to prevent the settled particles and dust from falling around the smoke exhaust device. After collection, the settled particles and dust can be better treated uniformly to avoid environmental pollution. In addition, the recycled metal particles can be economically utilized.
[0042] Compared with the prior art, the smoke exhaust device provided by the embodiment can block the smoke from being directly discharged into the air when the smoke is discharged from the smoke exhaust port 110 of the smoke stack body 100, change the flow direction of the smoke, make the smoke enter the flow guide cavity 220a from the flow guide outlet 210a at the lower end, and reduce the flow rate of the smoke, so that the particles and dust in the smoke can automatically sink, the gas can be discharged from the aperture group 223 on the side wall of the flow guide body 220, and finally the particles and dust that sink are collected from the dust collecting port 224 by the collecting assembly 300, thereby preventing the accumulation of particulate matters near the smoke exhaust device, effectively preventing the rust of the roof and facilities near the smoke exhaust device, further reducing the particles and dust discharged into the environment, and protecting personal safety.
[0043] In order to more clearly describe the technical solutions of the present application, the smoke exhaust device provided by the embodiment is described below, as follows.
[0044] In the embodiment, the flow guide cover 210 includes a cover body 211 and a flow guide plate 212. The inside of the cover body 211 forms a closed cavity. The flow guide plate 212 is arranged in the cover body 211, and the flow guide plate 212 is used to guide the wind of the smoke exhaust port 110 to the flow guide outlet 210a.
[0045] Further, the top wall of the inner cavity of the cover body 211 is outwardly inclined on both sides, so as to guide the smoke from the periphery of the cover body 211 to the flow guide outlet 210a, and disperse the smoke to reduce the flow resistance.
[0046] The flow guide plate 212 is arranged in the middle of the cover body 211, and a preset angle is formed between the flow guide plate 212 and the inner cavity side wall of the cover body 211, so as to further disperse and guide the smoke to the peripheral wall of the inner cavity of the cover body 211, so that the smoke can better enter the flow guide outlet 210a.
[0047] Further, the flow guide plate 212 is in a conical structure, and the flow guide plate 212 is arranged in an inverted manner, that is, the top of the cone faces the smoke exhaust port 110, so as to better guide the smoke to the peripheral wall of the inner cavity of the cover body 211, so that the smoke can be dispersed into the flow guide cavity 220a.
[0048] The flow guide body 220 is in a cylindrical structure, and the cylindrical flow guide body 220 is sleeved on the outer peripheral surface of the smoke stack body 100 and is welded to the smoke stack body 100.
[0049] The flow guide body 220 includes a flow guide section 221 and a smoke exhaust section 222 in sequence from top to bottom along the length direction of the smoke stack body 100. The flow guide section 221 is closed on the periphery, and the aperture group 223 is formed in the smoke exhaust section 222.
[0050] It can be understood that the purpose of the flow guide section 221 in a closed arrangement is mainly to guide the flue gas downward in the vertical direction to limit the flow direction of the flue gas, so as to prevent the flue gas from being directly discharged after entering the flow guide cavity 220a, thereby taking away the particles and dust in the flue gas. Through the limiting effect of the flow guide section 221, the particles and dust will flow downward in the vertical direction, and under the action of their own gravity, they can better realize sedimentation and improve the collection effect. The smoke exhaust section 222 is arranged below, so that after the flue gas flow reaches the expected value, the airflow is stable and then discharged, thereby reducing the emission of particles and dust.
[0051] Optionally, the pore group 223 includes a plurality of smoke exhaust holes uniformly distributed on the wall body of the flow guide body 220. The number and aperture size of the smoke exhaust holes can be designed according to actual production needs, and are not specifically limited in the embodiment.
[0052] In the embodiment, the bottom of the flow guide body 220 is arranged to be inclined to the dust collecting port 224. In this way, when the particles and dust fall to the bottom of the flow guide body 220, they can enter the dust collecting port 224 in time, avoiding the problem of accumulation and blockage, and being discharged more smoothly.
[0053] The collection assembly 300 includes a dust receiving container 310 and a sensor 320 for detecting the weight of the dust receiving container 310. The circumferential wall of the chimney body 100 is provided with a bracket 330, the bracket 330 is located below the dust collecting port 224, the dust receiving container 310 is detachably arranged on the bracket 330, and the sensor 320 can be arranged at the bottom of the dust receiving container 310.
[0054] Optionally, the dust receiving container 310 can be a dust receiving barrel. The sensor 320 is a weighing sensor 320 or a pressure sensor 320.
[0055] Please refer to Figure 3 and Figure 4 In some embodiments, the dust receiving container 310 can be hung at the bottom of the flow guide body 220, the sensor 320 is selected as a tension sensor 320, and is arranged between the dust receiving container 310 and a hanging piece 340.
[0056] In this way, the sensor 320 can feedback the weight of the dust receiving container 310 to the control center in real time, so as to judge whether the dust receiving container 310 is full, and clean the dust receiving container 310 in time.
