Description

Technical Field

[0001] This utility model relates to the technical field of rolling mill guide equipment, and in particular to a dust removal guide for the exit of a bar mill. Background Technology

[0002] During the bar rolling process, a large amount of dust is often generated at the mill exit. This dust not only affects the working environment but may also damage equipment and even affect product quality. Therefore, dust removal devices are usually installed at the mill exit to purify the air and protect equipment and product quality.

[0003] Existing rolling mill exit dust removal devices generate a lot of wastewater during the dust removal process when using water mist dust removal. If this wastewater is discharged directly, it will not only waste water resources, but may also cause secondary pollution to the environment. Therefore, we propose a dust removal guide for bar mill exit. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a dust removal guide for the exit of a bar mill. This can solve the problem that existing dust removal devices at the exit of mills generate a lot of wastewater during the dust removal process when using water mist dust removal. If this wastewater is discharged directly, it will not only waste water resources, but may also cause secondary pollution to the environment.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a dust collector guide for the outlet of a bar mill, comprising:

[0025] The catheter box 1 and the outlet catheter 2 are fixedly installed inside the catheter box 1;

[0026] The dust removal water circulation structure is located on the outlet duct 2.

[0027] The dust removal water circulation structure includes an inlet pipe 3, a connecting pipe 6, a first water pump 7, a water storage tank 8, and a dust removal nozzle 13. The inlet pipe 3 is fixedly installed on one side of the outlet conduit 2 and is connected to the interior of the outlet conduit 2. The dust removal nozzle 13 is fixedly installed at the outlet of the inlet pipe 3 and is located on the outlet conduit 2. The end of the inlet pipe 3 away from the outlet conduit 2 is fixedly connected to the connecting pipe 6. The end of the connecting pipe 6 away from the inlet pipe 3 is fixedly connected to the output end of the first water pump 7. The first water pump 7 is fixedly installed on the top of the water storage tank 8 and is connected to the interior of the water storage tank 8.

[0028] The dust removal water circulation structure also includes a drainage hopper 5, a circulating filter box 12, a filter screen 10, and a second water pump 9. A water leakage hole 4 is provided at the bottom of the outlet pipe 2. The drainage hopper 5 is fixedly connected to the bottom of the outlet pipe 2 and communicates with the inside of the water leakage hole 4. The bottom end of the drainage hopper 5 communicates with the inside of the circulating filter box 12. The filter screen 10 is slidably installed inside the circulating filter box 12. A sealing gasket is provided at the connection between the filter screen 10 and the circulating filter box 12. The second water pump 9 is fixedly installed on the side of the circulating filter box 12 near the water storage tank 8. The input end of the second water pump 9 communicates with the inside of the circulating filter box 12, and the output end of the second water pump 9 communicates with the inside of the water storage tank 8.

[0029] A fixed frame 14 is fixedly connected to the top of the circulating filter box 12. A baffle 11 is slidably connected inside the fixed frame 14. One side of the baffle 11 contacts the filter screen 10. A spring 15 is fixedly connected to the top of the fixed frame 14. The top of the spring 15 is fixedly connected to the inner top wall of the baffle 11. A water exchange pipe 16 communicating with the inside of the water storage tank 8 is fixedly connected to one side of the tank.

[0030] Furthermore, when using this device, as the red-hot steel is passed through the outlet conduit 2, the first water pump 7 is started by connecting an external power source. The first water pump 7 draws water from the water storage tank 8 and discharges it into the inlet pipe 3 through the connecting pipe 6. Subsequently, the water is sprayed out as water mist through the dust removal nozzle 13, which facilitates the dust suppression treatment of the dust generated by the red-hot steel in the outlet conduit 2. When the water mist accumulates to a certain amount, it will fall into the drain hopper 5 through the drain hole 4 under the guidance of the inner wall of the outlet conduit 2, thus facilitating its flow into the circulating system. The filter box 12 is used so that when the sewage in the circulating filter box 12 accumulates to a certain amount, the second water pump 9 is started by connecting an external power source. The second water pump 9 can draw the sewage in the circulating filter box 12 and discharge it into the water storage tank 8. When the second water pump 9 draws sewage, the filter screen 10 can filter the dust particles in the sewage. When the operator pulls the baffle 11, the baffle 11 moves and stretches the spring 15, causing the baffle 11 to separate from the filter screen 10, so that the filter screen 10 can be replaced or cleaned.

[0031] With the cooperation of the drainage hopper 5, the circulating filter box 12, the filter screen 10, the second water pump 9, and the baffle 11, the circulating filter box 12 can settle and filter the wastewater generated by dustfall. With the baffle 11 pulled out, it is easy to replace or clean the filter screen 10, and then the filtered water can be discharged into the water storage tank 8 for recycling, thus facilitating the recycling of water resources.

[0032] Working principle: When the red steel is passed through the outlet conduit 2, the first water pump 7 is started by connecting an external power source. The first water pump 7 draws water from the water storage tank 8 and discharges it into the inlet pipe 3 through the connecting pipe 6. Subsequently, the water is sprayed out as water mist through the dust removal nozzle 13, which facilitates the dust removal treatment of the dust generated by the red steel in the outlet conduit 2. When the water mist accumulates to a certain amount, it will fall into the drain hopper 5 through the drain hole 4 under the guidance of the inner wall of the outlet conduit 2, and then fall into the circulating filter box 12 through the drain hopper 5. When the sewage in the circulating filter box 12 accumulates to a certain amount, the second water pump 9 is started by connecting an external power source. The second water pump 9 can draw the sewage in the circulating filter box 12 and discharge it into the water storage tank 8. When the second water pump 9 draws sewage, the filter screen 10 can filter the dust particles in the sewage. When the operator pulls the baffle 11, the baffle 11 moves and stretches the spring 15, causing the baffle 11 to separate from the filter screen 10, which makes it easy to replace or clean the filter screen 10.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
