Description

Technical Field

[0001] This invention relates to the fields of metallurgy, chemical engineering, and other technical fields, and in particular to a water cooling device for a moving chute. Background Technology

[0002] In the 25MVA slag refining furnace of Polytitanium Technology's blast furnace slag titanium extraction demonstration line, hot slag is fed into the furnace via a slag car. The hot slag is poured into a mobile chute after being tilted by the slag car. The mobile chute is a welded structure made of Q345 steel. During the hot slag feeding process, it not only receives and collects all the hot slag but also plays an important guiding role in the slag turning process.

[0003] The problems with the mobile slag chute are as follows: 1. Difficulty in cleaning the chute. When slag is turned into the furnace, about 5% of the slag adheres to the bottom plate of the chute, with each layer of slag adhering to the bottom plate being about 100mm thick. The accumulated slag in the chute needs to be cleaned after every 3-4 furnace cycles. Currently, manual slag cleaning is used. A chain is laid on the bottom plate of the chute in advance. Before cleaning, the accumulated slag is cooled with water, and then the chain is dragged to loosen the slag, thus completing the cleaning operation. The entire cleaning operation takes about 180 minutes. If the slag contains iron, or if the bottom plate is cracked or deformed, the slag will solidify after cooling, and the chain will not be able to loosen the slag. Manual entry into the chute is required to use a pneumatic pick to clean the slag, further extending the cleaning time and seriously hindering smooth production. 2. Deformation of the chute due to heat. Currently, the chutes are made of welded steel plates. Due to factors such as heat deformation and stress release, the overall manufacturing strength of the steel plates is low. After continuous slag turning operations, the bottom plate deforms due to heat, causing the chute to drop downwards and deform, scraping against the furnace cover and equipment in the slag discharge area, seriously affecting the continuity of production. At the same time, the cracking and deformation of the bottom plate causes slag to overflow during slag turning operations, burning cables and other spare parts, and significantly increasing the difficulty of slag cleaning operations.

[0028] The 63MVA slag furnace mobile chute water cooling device includes: a combined water cooling plate 2, a mating interface and a flexible docking unit 16;

[0029] The interface is located on the side of the mobile chute 1; the flexible docking unit automatically docks with the mobile chute through the interface to supply water to the combined water-cooled plate placed in the mobile cold tank.

[0030] It should be noted that the combined water-cooled plate is composed of spliced ​​cooling plates. The cooling plate contains a serpentine seamless steel pipe, preferably a DN40 serpentine seamless steel pipe. The thickness of the cooling plate is 120mm.

[0031] It should also be noted that the flexible docking unit includes: a spherical connector 5, a pneumatic cylinder 7, a water supply hose 8, and a flexible support component. The spherical connector, the pneumatic cylinder, and the water supply hose are connected in sequence. A flexible support component is provided at the lower part of the pneumatic cylinder to accommodate installation errors, vehicle body deformation, and the tilt of the moving chute.

[0032] The flexible support component includes: a flexible support bushing 9, a flexible support junction bushing 12, a front flexible support 11, and a rear flexible support 10. The flexible support bushing is connected to the rear flexible support via a pin, allowing for small-range movement in six directions: forward / backward, left / right, and up / down. The flexible support hinge bushing is connected to the front flexible support via a pin, allowing for small-range movement in four directions: forward / backward and up / down.

[0033] The flexible docking unit further includes: a pneumatic solenoid valve 6, which is connected to the rod-side and rodless-side chambers of a pneumatic cylinder via a pneumatic pipeline. Adjusting the solenoid valve controls the extension and retraction of the pneumatic cylinder. The pneumatic solenoid valve is used to adjust the pressure between the spherical joint and the conical seal to ensure the service life of the conical seal. The flexible docking unit also includes: a flow meter 13, which is connected to the water supply hose and is used to display the water flow rate. The flexible docking unit further includes: an electric ball valve 14, which is connected to the flow meter and is used to control whether water is supplied to the water supply hose.

[0035] The following is a detailed explanation of the operation of the mobile chute water cooling unit for the 63MVA slag furnace:

[0036] First, when the slag truck arrives at the slag-turning station, the mobile chute is activated and moved to the receiving station, achieving precise positioning through an automatic detection and positioning device. Then, the flexible docking device is activated, the left electromagnet of the pneumatic solenoid valve opens, and compressed air enters the rodless chamber of the pneumatic cylinder through the pipeline. The spherical connector of the pneumatic cylinder extends, inserts into the conical hole of the conical water collection plate, and slides along the wall of the conical hole to dock with the conical seal. The flexible support at the tail end adjusts the position of the pneumatic cylinder in real time according to the movement of the spherical connector, ensuring that the spherical connector and the conical seal are perpendicularly docked, maintaining the air pressure of the pneumatic cylinder, so that the entire spherical connector and the conical seal are in complete contact and sealing. Then... Next, the electric ball valve in the flexible docking unit is opened, and the water supply pipeline begins to supply water. Cold water enters the combined water-cooled plate built into the mobile chute through the water supply hose. At the same time, the mobile chute begins the slag collection operation. Water is continuously circulated in the combined water-cooled plate to keep the temperature of the bottom plate of the mobile chute within the normal operating range and reduce the amount of slag adhering to the bottom plate of the mobile chute. The heated water in the combined water-cooled plate is discharged through the outlet hose. Finally, after the slag collection is completed, the electric ball valve is closed to stop the water supply. The right electromagnet of the pneumatic solenoid valve is opened, and compressed air enters the rod chamber of the pneumatic cylinder through the pipeline. The ball joint of the pneumatic cylinder retracts. After reaching the limit position, the air supply stops, and the mobile chute is started to return to the slag cleaning position.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
