Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a cooling device for auxiliary spray guns of side-blown furnaces. Background Technology

[0002] A side-blown furnace is a type of metallurgical smelting furnace. Its core feature is that oxygen-enriched air, fuel, or powdered materials are injected into the molten pool through lances installed on the side wall of the furnace body, thereby enhancing the smelting process. The lances in a side-blown furnace are key equipment in the metallurgical smelting process, and the cooling device is a guarantee system to ensure the long-term stable operation of the lances.

[0003] While the spray gun temperature is reduced through water cooling circulation, the water temperature also rises as the spray gun temperature increases. After prolonged use, scale can easily form, causing the scale to clog the pipes and reduce the flow of cooling water. This creates a vicious cycle, exacerbating the scaling and affecting the cooling effect of the spray gun.

[0004] Therefore, how to provide a cooling device for the auxiliary spray gun of a side-blown furnace is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a cooling device for the auxiliary spray gun of a side-blown furnace. By activating the transmission component, a scale removal brush can be driven to scrape scale inside the cooling jacket, which can prevent scale buildup from affecting the cooling effect and solve the problems mentioned in the background art.

[0006] A cooling device for auxiliary spray guns of a side-blown furnace according to an embodiment of the present invention includes a spray gun housing and a fixing plate. A fixing block is fixedly connected to the front end of the spray gun housing. A rotating motor is fixedly connected to the rear side of the fixing plate. A drive gear is fixedly connected to the output end of the rotating motor. A drive threaded rod is fixedly connected to the rear side of the drive gear. An internal gear ring plate is meshed with the outer wall of the drive gear. Two driven gears are meshed with the inner wall of the internal gear ring plate. A threaded rod is fixedly connected inside the driven gear. A scale cleaning brush is threaded between the outer wall of the threaded rod and the drive threaded rod.

[0007] As a preferred embodiment of this utility model: a fixing ring plate is fixedly connected to the outer wall of the front end of the spray gun housing, and a fixing plate is fixedly connected to the bottom of the fixing ring plate.

[0008] As a further preferred embodiment of this utility model: a connecting sleeve is fixedly connected to the front end of the outer wall of the spray gun housing, and a water pumping connecting pipe is snapped into the left side of the outer wall of the connecting sleeve.

[0009] As a further preferred embodiment of this utility model: the bottom end of the water pumping connection pipe is fixedly connected to the input end of the water pump, a water pump is provided on the left side of the spray gun housing, and a drain connection pipe is fixedly connected to the output end of the water pump.

[0010] As a further preferred embodiment of this utility model: a filter box is fixedly connected to the left side of the drain connecting pipe, and a filter pull-out box is slidably connected inside the filter box.

[0011] As a further preferred embodiment of this utility model: a water pump is provided on the right side of the spray gun housing, a water pump is fixedly connected to the input end of the water pump, and a water tank is fixedly connected to the right end of the water pump.

[0012] As a further preferred embodiment of this utility model: the output end of the water pump is fixedly connected to a water supply pipe, and the left side of the water supply pipe is snapped into the connecting sleeve.

[0013] As a further preferred embodiment of this utility model: a spray gun nozzle is fixedly connected inside the spray gun housing, and a cooling jacket is provided on the inner wall of the spray gun housing.

[0014] The beneficial effects of this utility model are:

[0015] When it is necessary to scrape scale from the cooling jacket inside the spray gun housing, first start the rotating motor to drive the drive gear to rotate. The rotation of the drive gear drives the internal gear ring plate to rotate, which in turn drives the driven gear on its inner wall to rotate. The rotation of the driven gear and the drive gear drives the threaded rod and the drive threaded rod on the rear side to rotate. The rotation of the drive threaded rod and the threaded rod drives the scale cleaning brush to move back and forth, scraping off the scale residue stuck in the cooling jacket inside the spray gun housing. This effectively prevents scale from accumulating inside the cooling jacket, which would affect the circulation of cooling water and thus fail to cool the spray gun housing.

[0027] By starting the rotating motor 17, the driving gear 18 can be driven to rotate. The rotation of the driving gear 18 drives the internal gear ring plate 22 to rotate. The rotation of the internal gear ring plate 22 drives the driven gear 23 on the inner wall to rotate. The rotation of the driven gear 23 drives the driving threaded rod 21 and the threaded rod 20 on the rear side to rotate. The rotation of the threaded rod 20 and the driving threaded rod 21 drives the scale cleaning brush 14 to scrape the scale in the cooling jacket 10.

[0028] refer to Figure 1 , Figure 2 , Figure 5 As shown, a connecting sleeve 3 is fixedly connected to the front end of the outer wall of the spray gun housing 1. A water pumping connecting pipe 8 is snapped into the left side of the outer wall of the connecting sleeve 3.

[0030] Working principle:

[0031] When it is necessary to scrape scale from the cooling jacket 10 inside the spray gun housing 1, firstly, start the rotating motor 17 to drive the drive gear 18 to rotate. The rotation of the drive gear 18 drives the internal gear ring plate 22 to rotate, which in turn drives the driven gear 23 on its inner wall to rotate. The rotation of the driven gear 23 and the drive gear 18 drives the threaded rod 20 and the drive threaded rod 21 on the rear side to rotate. The rotation of the drive threaded rod 21 and the threaded rod 20 drives the scale cleaning brush 14 to move back and forth, scraping off the residual scale adhering to the cooling jacket 10 on the inner wall of the spray gun housing 1. This effectively prevents scale from accumulating in the cooling jacket 1. The buildup inside the spray gun housing 1 affects the circulation of cooling water, preventing it from effectively cooling the spray gun housing 1. The water pump 5 is activated, drawing cooling water from the water tank 7 via the pumping pipe 6 at its input end. The cooling water is then discharged into the cooling jacket 10 inside the spray gun housing 1 via the pumping pipe 4 at its output end. Next, the pump 11 is activated, drawing water from the cooling jacket 10 inside the spray gun housing 1 via the pumping connection pipe 8 at its input end. The water containing scale is then discharged into the filter pull-out box 13 inside the filter housing 9 via the drain connection pipe 12 at its output end. The scale is then filtered through the filter screen inside the filter pull-out box 13.
