Description

Technical Field

[0001] This utility model relates to the field of dust collection at the outlet of a cold slag machine. Background Technology

[0002] A slag cooler, also known as a slag chiller, is a mechanical device used to process high-temperature slag. Slag cooled by a slag cooler has relatively stable physical and chemical properties and can be used to manufacture building materials such as cement and bricks, as well as as road base materials, finding wide application in various industries.

[0003] However, existing slag coolers lack dust suppression equipment at their slag discharge ports. Since the fuel used in thermal power plants is mostly powder, the slag discharged from the slag cooler has a small particle size and a high degree of dryness. Furthermore, due to the drop between the discharge port and the conveyor belt, dust generation is inevitable. This dust reduces visibility in the surrounding environment, particularly impacting the health of workers. Currently, there is no corresponding solution to this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dust collection device for the outlet of a cold slag machine that is installed at the slag discharge port to avoid dust generation by means of negative pressure air collection and can further recover dust and powder.

[0005] The equipment includes a dust suction pipe fixing component, which includes a clamp, and the clamp is fixed to the slag discharge pipe of the slag cooler. A crank arm is provided below the aforementioned hoop. The crank arm is formed by two connecting rods hinged together, and the two connecting rods are connected by bolts and threaded sleeves. The effect achieved by this is that, based on its hinged configuration, the orientation and position of the crank arm can be fixed by the hard limit between the bolts and threaded sleeves. The end of the crank arm is fixedly connected to a dust suction pipe, which is connected to a negative pressure air collection unit.

[0006] The effect achieved is that, through the fixed connection between the dust suction pipe fixing component and the slag discharge pipe, the crank arm can be adjusted so that the air outlet of the dust suction pipe faces the slag discharge port; the negative pressure air collection unit can then collect the dust in the slag discharge.

[0007] The beneficial effects of this utility model are: it solves the problem of severe dust generation during the discharge of cold slag machines in the prior art, and realizes the real-time collection of dust at the discharge position of the cold slag machine in the form of an auxiliary device. Furthermore, the equipment has a simple structure and is easy to maintain. Attached Figure Description

Detailed Implementation

[0009] Reference Figure 1 The present invention provides a dust collection device for the outlet of a cold slag machine, which includes a dust suction pipe 3 fixing component. The dust suction pipe 3 fixing component includes a clamp 1, which is fixed to the slag discharge pipe of the cold slag machine. A crank arm 2 is provided below the clamp 1. The crank arm 2 is formed by two connecting rods hinged together, and the two connecting rods are connected by bolts and threaded sleeves. The effect achieved by this is that, based on its hinged configuration, the orientation and position of the crank arm 2 can be fixed by the hard limit between the bolts and threaded sleeves. The end of the crank arm 2 is fixedly connected to the suction pipe 3, and the suction pipe 3 is connected to the negative pressure air collection unit.

[0010] The effect achieved is that, through the fixed connection between the dust suction pipe 3 and the slag discharge pipe, the crank arm 2 is adjusted so that the air outlet of the dust suction pipe 3 faces the slag discharge outlet; the negative pressure air collection unit can collect the dust in the slag discharge by operating.

[0011] In Example 1, the front end of the suction pipe 3 is in the form of a flared mouth, and a hoop 1 is provided at its rear. The hoop 1 is fixedly connected to the crank arm 2.

[0012] Furthermore, the suction pipe 3 is a corrugated pipe, and a metal flexible hose 4 is fixedly installed on its outer wall.

[0013] The effect achieved is that, based on the bendable and plastic properties of corrugated pipes, the flexible metal hose 4 on its outer wall can assist in pipe shaping, which facilitates pipe layout and avoids affecting the operation of equipment such as belt conveyors.

[0014] Example 2: The negative pressure air collection unit includes a cyclone separator 6. The upper side of the cyclone separator 6 is an air inlet, and an air outlet chamber is provided on it. An air outlet is provided on the side of the air outlet chamber. A negative pressure fan 5 is provided on the upper part of the air outlet chamber, and the negative pressure fan 5 is connected to the chamber of the cyclone separator 6. The suction pipe 3 is connected to the air inlet.

[0015] The effect achieved is that air separation and settling are accomplished through the cyclone separator 6.

[0016] Furthermore, a support is provided on the outside of the cyclone separator 6.

[0017] This achieves the effect of making it easier to install equipment on the side of the slag chute.

[0018] Furthermore, a powder collection cylinder is provided below the cyclone separator 6.

[0019] This makes it easier to reuse the recycled powder.

[0020] Furthermore, the air outlet pipe is connected to the bag filter 8.

[0021] This achieves the effect of improving the purification and emission efficiency, and also further prevents dust from being generated.
