Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal equipment which utilizes inertia to collect dust and automatically discharges the dust. Background Art

[0002] With the development of modern industry, the impact of dust on the environment and human health is becoming more and more serious. In recent years, the country has attached increasing importance to environmental protection and global warming is a serious phenomenon. In order to advocate energy conservation and carbon reduction, the environmental protection industry has flourished. In order to maintain a clean production environment, it is necessary to clean up dust-contaminated places in a timely manner and promote a dust-free working environment. In addition, with the development of modern industry, the impact of dust on the environment and human health is becoming more and more serious. Effectively controlling dust pollution and purifying the living environment of mankind has become a consensus of everyone. Dust removal equipment came into being. At present, dust removal equipment is not only widely used in the dust removal and purification of non-fiber industrial dust and material recycling in various industrial and mining enterprises such as metallurgy, building materials, machinery, chemicals, and mining, but also mainly used in the electronics production industry,

[0003] There are two types of dust collectors commonly used now, cyclone dust collectors and pulse dust collectors. The characteristics of cyclone dust collectors are: high reliability, wide adaptability to the dust concentration of the air to be treated, and simple structure, but the dust removal rate of this dust collector is low, and the dust content of the air discharged after it is treated is high, which is difficult to meet the requirements of safe air discharge standards. The characteristics of pulse dust collectors are: high dust removal rate, and the air discharged after it is treated can meet the requirements of safe air discharge standards, but this pulse dust collector has low reliability and has great restrictions on the dust concentration of the air to be treated. In actual use, the dust bag is often blocked quickly due to the high dust concentration in the air to be treated, and the pulse dust collector cannot work normally. The pulse dust collector has high requirements for exhaust gas. Exhaust gas with too high temperature or too high humidity is not good for the use of filter materials in the filter bag, affecting the dust removal efficiency of the filter bag. Existing dust collectors have disadvantages such as unsatisfactory cleaning effect, low purification efficiency, short filter bag life, and large maintenance workload, which seriously affect the normal and efficient use of filters. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a dust removal device which utilizes inertia to collect dust and automatically discharges the dust. The dust removal device has a simple structure and can realize automatic discharge. At the same time, the dust collection efficiency of large particles is high, the maintenance is convenient, and the service life is long.

[0005] In order to solve the above technical problems, the utility model provides a dust removal equipment that utilizes inertia to collect dust and automatically discharges the dust, including a main body, wherein an air inlet and an air outlet are arranged on the top of the main body, an air inlet chamber and an air outlet chamber are arranged inside the main body at positions corresponding to the air inlet and the air outlet, a partition baffle is arranged between the air inlet chamber and the air outlet chamber, and a maze baffle is arranged at the bottom of the air inlet chamber and the air outlet chamber; a conical bucket is arranged at the bottom of the main body, a discharge pipe is arranged at the bottom of the conical bucket, and a space bag is arranged at the discharge pipe.

[0006] Furthermore, inspection ports are provided on the main body and the conical bucket.

[0007] Furthermore, the labyrinth baffle comprises a connected straight plate structure and an inclined plate structure, and the angle between the straight plate structure and the inclined plate structure is 150°.

[0008] Furthermore, the discharge port at the bottom of the discharge pipe includes a welding plate, a rubber plate and a pressing plate, and the angle between the welding plate and the horizontal direction is 45°.

[0009] Furthermore, the feed pipe is a circular welded pipe, and a manual butterfly valve is provided on the feed pipe.

[0010] Furthermore, the body is made of carbon steel.

[0011] The beneficial effects of the utility model are as follows: when the device is used, when the dust-laden airflow encounters a labyrinth plate arranged on the path that the airflow must pass through during its flow, the gas bypasses the obstacle, while the particles continue to move forward due to the inertia effect, collide with the obstacle and are captured, thereby separating the two; the dust slides down through the lower hopper and is deposited at the bottom, and when it accumulates to a certain amount, its own gravity can overcome the negative pressure to push the rubber plate open and fall into the space bag; the weight of the remaining powder gradually decreases until the negative pressure cannot be overcome, and the rubber sealing plate is re-engaged, and will be opened again when the next powder weight exceeds the limit, thereby realizing the function of automatic unloading. The dust removal equipment has a simple structure, high efficiency in capturing large dust particles, convenient maintenance, and a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figures 1 to 3 As shown, an embodiment of the dust removal equipment of the utility model which utilizes inertia to collect dust and automatically discharges the dust comprises a main body 1, an air inlet 2 and an air outlet 3 are arranged on the top of the main body 1, an air inlet chamber 4 and an air outlet chamber 5 are arranged inside the main body 1 at positions corresponding to the air inlet 2 and the air outlet 3, a partition baffle 6 is arranged between the air inlet chamber 4 and the air outlet chamber 5, and a labyrinth baffle 7 is arranged at the bottom of the air inlet chamber 4 and the air outlet chamber 5; a conical bucket 8 is arranged at the bottom of the main body 1, a discharge pipe 9 is arranged at the bottom of the conical bucket 8, and a space bag 10 is arranged at the discharge pipe 9.

[0023] When in use, dust-laden gas enters the dust removal device from the air inlet, and the particles flow downward along the direction of the airflow. When encountering the labyrinth baffle 7 set on the path that the airflow must pass during the flow, the gas bypasses the obstacle, while the particles continue to move forward due to the inertia effect, collide with the obstacle and are captured, thereby separating the two. The flow direction of the labyrinth baffle 7 is opposite to the direction of the airflow, which can increase the impact area of ​​the particles and ensure that the particles will not be discharged along with the airflow, thereby increasing the dust removal efficiency.

[0024] The feeding pipe 9 adopts a circular welded pipe, and a manual butterfly valve 15 is arranged on the feeding pipe 9; the feeding port at the bottom of the feeding pipe 9 includes a welding plate 12, a rubber plate 13 and a pressing plate 14, and the angle between the welding plate 12 and the horizontal direction is 45°, and the welding plate 12 and the feeding pipe 9 are welded and fixed at the intersection. Under normal circumstances, the rubber plate 13 of the feeding port is closely connected with the circular welded pipe under the action of negative pressure, and the dust slides through the conical bucket 8 and settles at the bottom. When it accumulates to a certain amount, its own gravity can overcome the negative pressure and push the rubber plate 13 to fall into the space bag 10; the weight of the remaining powder gradually decreases until the rubber plate 13 is re-engaged after the negative pressure cannot be overcome, and it will open again when the weight of the powder exceeds the limit next time, thereby realizing the function of automatic feeding. The manual butterfly valve 15 at the feeding pipe 9 is in a normally open state. When the space bag 10 is full of particles and needs to be replaced or the dust removal equipment needs to be repaired, the manual butterfly valve 15 is closed to prevent the particles from flowing back or leaking.

[0025] Both the main body 1 and the conical bucket 8 are provided with an inspection port 11 for convenient operation and maintenance; the labyrinth baffle 7 includes a connected straight plate structure 71 and an inclined plate structure 72, the angle between the straight plate structure 71 and the inclined plate structure 72 is 150°, and the contact area is large, making it easier for particles to settle; the main body 1 is made of carbon steel material and has a high structural strength.
