Description

Technical Field

[0001] This utility model relates to the field of steelmaking auxiliary equipment technology, and more specifically, to a high-efficiency dust removal device for steelmaking. Background Technology

[0002] Steelmaking refers to the process of putting scrap steel or pig iron into a steelmaking furnace and smelting it according to a certain process to remove excess carbon and other impurities, and adjusting the element ratio through chemical reactions to obtain steel with the required properties. The main purpose is to improve the performance of steel to meet the needs of engineering and construction materials. Dust removal devices are usually installed in the steelmaking process for dust removal.

[0003] A search revealed a high-efficiency dust removal device for the steelmaking industry disclosed in Chinese Patent Publication No. CN215463025U. Although the device uses a guiding mechanism to move dust and airflow towards the adsorption mechanism, and the magnetic plate of the adsorption mechanism adsorbs iron filings mixed in the dust, thus separating the dust and iron filings, the limited contact range between the dust airflow and the magnetic plate makes it difficult to fully adsorb the iron filings mixed in the dust, thereby affecting the separation and removal effect of the iron filings. Based on this, the present invention designs a high-efficiency dust removal device for steelmaking to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency dust removal device for steelmaking, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency dust removal device for steelmaking includes a body with a partition dividing it into an adsorption chamber and a dust settling chamber. A dust-collecting fan is fixedly installed on the outside of the body, and a duct is fixedly connected between the outlet of the dust-collecting fan and the adsorption chamber. Two upward-sloping baffles are fixedly installed at intervals on the upper part of the adsorption chamber, and two downward-sloping baffles are fixedly installed at intervals on the lower part of the adsorption chamber. The upward and downward-sloping baffles are staggered. Electromagnetic plates are fixedly installed on both the upward and downward-sloping baffles. Ventilation openings are provided on the side of the partition. Two chip collection components are fixedly arranged at intervals on the bottom of the adsorption chamber. A first filter screen is fixedly installed inside the dust settling chamber, and an air outlet is provided on the top side of the dust settling chamber. A second filter screen is fixedly installed inside the air outlet. A water pumping component is provided on the dust settling chamber, and a longitudinal spraying component and a transverse spraying component are provided on the water pumping component.

[0007] As a preferred technical solution of this utility model, the chip collection assembly includes a chip collection frame and a sealing plate. The chip collection frame is fixedly connected to the bottom of the adsorption chamber, and the sealing plate slides through the side of the chip collection frame. A T-shaped stud is threadedly connected between the chip collection frame and the sealing plate.

[0008] As a preferred technical solution of this utility model, the water pumping assembly includes a water pump and a water guide pipe. The water pump is fixedly installed at the upper end of the dust settling chamber, the water guide pipe is fixedly connected to the outlet end of the water pump, the inlet end of the water pump is fixedly connected to the water pump pipe, and a water inlet is provided at one end of the water pump pipe.

[0009] As a preferred technical solution of this utility model, the longitudinal spraying assembly includes a longitudinal spraying pipe and a plurality of nozzles I distributed at equal intervals. The longitudinal spraying pipe passes through the top of the dust settling chamber and is fixedly connected to the bottom end of the water guide pipe. The nozzles I are fixedly connected to the bottom of the longitudinal spraying pipe.

[0010] As a preferred technical solution of this utility model, the transverse spray assembly includes a transverse spray pipe and a plurality of nozzles II distributed at equal intervals. The transverse spray pipe passes through the side of the dust settling chamber and is fixedly connected to one side of the water guide pipe. The nozzles II are fixedly connected to the side of the transverse spray pipe.

[0011] As a preferred technical solution of this utility model, a drain pipe is fixedly connected to the bottom of the dust settling chamber, and a switch valve is provided on the drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a dust suction fan to draw dust airflow into the adsorption chamber. The staggered upper and lower inclined baffles can block and disturb the dust airflow. Each upper and lower inclined baffle is equipped with an electromagnetic plate, which helps to increase the contact range between the passing dust airflow and the energized electromagnetic plate, making it easier to fully adsorb iron filings mixed in the dust and better ensure the separation and removal effect of iron filings. Furthermore, by setting up longitudinal and transverse spray components, a water pump is used to draw water through the water guide pipe into the longitudinal and transverse spray pipes. The water sprayed by nozzles I and II can efficiently adsorb and remove dust.

[0014] 2. By setting up a chip collection component, after the dust removal is finished, if it is necessary to clean the iron filings on the electromagnetic plate, the electromagnetic plate is de-energized, and the iron filings can fall down along the electromagnetic plate into the chip collection frame, which is convenient for the iron filings to be temporarily stored. If it is necessary to clean the iron filings in the chip collection frame, the T-shaped stud is loosened, and the sealing plate is slid outward along the side of the chip collection frame to discharge the iron filings, thus facilitating the centralized cleaning of the iron filings in the chip collection frame.

A water pumping component 7 is provided on the dust settling chamber 103. A longitudinal spraying component 8 and a transverse spraying component 9 are provided on the water pumping component 7.

[0022] Among them, such as Figure 1 As shown, the chip collection assembly 6 includes a chip collection frame 601 and a sealing plate 602. The chip collection frame 601 is fixedly connected to the bottom of the adsorption chamber 102, and the sealing plate 602 slides through the side of the chip collection frame 601. A T-shaped stud 603 is threadedly connected between the chip collection frame 601 and the sealing plate 602.

[0023] Among them, such as Figure 2 As shown, the water pumping assembly 7 includes a water pump 701 and a water guide pipe 702. The water pump 701 is fixedly installed at the upper end of the dust settling chamber 103. The water guide pipe 702 is fixedly connected to the outlet end of the water pump 701. The inlet end of the water pump 701 is fixedly connected to a water pumping pipe 703. A water inlet is provided at one end of the water pumping pipe 703, so that the water pumping pipe 703 can be connected to the water supply pipeline.

[0024] Among them, such as Figure 2 As shown, the longitudinal spray assembly 8 includes a longitudinal spray pipe 801 and a plurality of nozzles I802 that are evenly spaced.

The water liquid that adsorbs the dust is filtered by the first filter screen 105 and then falls into the lower part of the dust settling chamber 103. The airflow is finally filtered by the second filter screen 107 in the air outlet 106 and then discharged. After the dust removal is finished, if it is necessary to clean the iron filings on the electromagnetic plate 5, the electromagnetic plate 5 is de-energized and the iron filings can fall down along the electromagnetic plate 5 into the chip collection frame 601 for convenient collection and temporary storage. If it is necessary to clean the iron filings in the chip collection frame 601, the T-shaped stud 603 is loosened and the sealing plate 602 is slid outward along the side of the chip collection frame 601 to discharge the iron filings, thus facilitating the centralized cleaning of the iron filings in the chip collection frame 601.
