Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of metallurgical devices, and more specifically, relates to a rotary metallurgical furnace angle adjustment display device. Background Art
[0002] There is a spray gun buried at the bottom of the bottom blowing furnace. During the production process, a certain pressure of air and oxygen is blown into the spray gun, and the spray gun is turned to the bottom of the furnace body and completely immersed in the melt. Figure 1 As shown in the figure, after batching, copper concentrate is fed into the bottom-blown furnace via a conveyor belt. At a temperature of 1200°C, the copper concentrate reacts chemically with oxygen supplied by lances at the bottom of the furnace. The blast of oxygen from the lances creates an intense stirring state in the molten pool. Charge material is added from the top of the furnace to the surface of the molten pool and is rapidly drawn into the stirring melt, creating favorable conditions for heat and mass transfer. The oxidation reaction releases a large amount of heat, rapidly melting the charge material to form matte and slag. During normal maintenance, large-scale power outages, and other sudden equipment incidents, the bottom-blown furnace must be rotated to a certain angle to allow the lances to release molten metal before proceeding.
[0003] The bottom-blowing furnace master controller manually rotates the furnace during rotation. In the event of an emergency, failure to rotate the furnace body in time can cause melt to backflow into the oxygen lance, burning the metal hose and even causing a major equipment accident. During on-site rotation of the bottom-blowing furnace, manual identification of markings on the furnace body is used to determine whether the furnace is properly rotated and whether the oxygen lance has protruded from the melt surface. In the event of sudden power outages or tripping of the sulfuric acid blower, poor visibility makes it impossible to determine whether the bottom-blowing furnace body is properly rotated. If the bottom-blowing furnace body is not properly rotated, the spray gun, which is immersed in the melt, will not release the melt, allowing the high-temperature melt to backflow into the spray gun and then leak out of the furnace body through the spray gun, potentially causing major fires and other equipment accidents. Rotating the furnace body too far can cause the melt inside the furnace to overflow through the feed port and flue, potentially causing burns, fires, and other major accidents. Utility Model Content

[0024] Example 1
[0025] like Figure 2 、 3 As shown, the angle adjustment and display device of the rotary metallurgical furnace includes a furnace body electronic tag 1, an electronic tag reading system 2, an angle calculation system 3, an angle display system 4, and a furnace body adjustment roller system 5; the furnace body adjustment roller system 5 is installed at the bottom of the bottom-blown furnace body 6, and the bottom-blown furnace body 6 is driven to rotate by the furnace body adjustment roller system 5. The furnace body electronic tag 1 is evenly installed along the circumferential surface of the bottom-blown furnace body 6, and the furnace body electronic tag 1 is provided with a number. The electronic tag reading system 2 and the furnace body electronic tag 1 are coordinated by radio, and the electronic tag reading system 2, the angle calculation system 3 and the angle display system 4 are electrically connected in sequence.
[0026] The electronic tag reading system 2 is used to read the number on the furnace body electronic tag 1 by transmitting radio induction. The angle calculation system 3 performs angle calculation by calculating the data read by the electronic tag reading system 2. The angle calculation system 3 displays the angle calculation result on the angle display system 4, so that the bottom blowing furnace master can intuitively see the working angle of the bottom blowing furnace. Then, the angle of the bottom blowing furnace body 6 is adjusted through the furnace body adjustment roller system 5 to accurately judge whether the bottom blowing furnace body is rotated to the right position, thereby avoiding major accidents such as burns to personnel and fire, and preventing the rotation angle from being too small, causing the high-temperature melt to flow back into the spray gun 7, and the rotation angle from being too large, causing the melt in the furnace to overflow out of the furnace body through the furnace body feeding port 8 and the furnace body flue port 9.
[0027] Example 2
[0028] like Figure 2 、 3 As shown, the angle adjustment and display device of the rotary metallurgical furnace includes a furnace body electronic tag 1, an electronic tag reading system 2, an angle calculation system 3, an angle display system 4, and a furnace body adjustment roller system 5; the furnace body adjustment roller system 5 is installed at the bottom of the bottom-blown furnace body 6, and the bottom-blown furnace body 6 is driven to rotate by the furnace body adjustment roller system 5. The furnace body electronic tag 1 is evenly installed along the circumferential surface of the bottom-blown furnace body 6, and the furnace body electronic tag 1 is provided with a number. The electronic tag reading system 2 and the furnace body electronic tag 1 are coordinated by radio, and the electronic tag reading system 2, the angle calculation system 3 and the angle display system 4 are electrically connected in sequence.
[0029] There are thirty-six furnace body electronic tags 1 evenly arranged, and their numbers are set in sequence from 1 to 36. With the center line of the bottom blowing furnace body 6 as the center of the circle, the angle between two adjacent furnace body electronic tags 1 is 10°. The smaller angle difference can make the angle calculated by the angle calculation system 3 more accurate.
[0030] When the post operator receives the instruction to rotate the bottom blowing furnace body 6, the post operator clicks the corresponding in / out button on the furnace body adjustment roller system 5, and the furnace body adjustment roller system 5 will rotate the bottom blowing furnace body 6 according to the direction, and the furnace body electronic tag 1 on the bottom blowing furnace body 6 will rotate with the bottom blowing furnace body 6. The electronic tag reading system 2 transmits radio induction to read the number on the furnace body electronic tag 1, and the angle calculation system 3 calculates the angle by calculating the data read by the electronic tag reading system 2. The angle calculation system 3 displays the angle calculation result on the angle display system 4, so that the bottom blowing furnace main control can intuitively see the working angle of the bottom blowing furnace, and then adjust the angle of the bottom blowing furnace body 6 through the furnace body adjustment roller system 5, accurately judge whether the bottom blowing furnace body is rotated into place, avoid major accidents such as burns and fires, and prevent the rotation angle from being too small, causing the high-temperature melt to flow back into the spray gun 7, and the rotation angle from being too large, causing the melt in the furnace to overflow out of the furnace body through the furnace body feeding port 8 and the furnace body flue port 9.
[0031] The furnace body adjustment roller system 5 includes a furnace body adjustment roller mechanism 51, a roller drive system 52, and an angle input control system 53. The furnace body adjustment roller mechanism 51 is installed at the bottom of the bottom blowing furnace body 6 and is rollingly connected to the bottom blowing furnace body 6. The roller drive system 52 is transmission-connected to the furnace body adjustment roller mechanism 51, and the angle input control system 53 is electrically connected to the angle input control system 53. After the staff sees the working angle of the bottom blowing furnace body 6 through the angle display system 4, they judge whether the bottom blowing furnace body 6 is rotated into place based on previous data. If not, the corresponding in / out angle is input through the angle input control system 53. The angle input control system 53 controls the roller drive system 52 to generate driving force for the furnace body adjustment roller mechanism 51, and drives the bottom blowing furnace body 6 to rotate through the furnace body adjustment roller mechanism 51.
[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
