[0014] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0015] like Figure 1 to Figure 2 As shown, a cooling device for a flow liquid gate of a horseshoe flame kiln comprises a gate channel 1, a sleeve 2 is sleeved on the outer periphery of the gate channel 1, and the two ends of the peripheral wall of the sleeve 2 are respectively connected to a water inlet pipe 4 and a water outlet pipe 3, the water inlet pipe 4 is connected to the outlet end of a water pump, and the water pump is not drawn in the present application, a plurality of heat dissipating fins 11 are sleeved and fixedly connected on the outer peripheral wall of the gate channel 1, and a gap is left between the outer side edges of the heat dissipating fins 11 and the inner wall of the sleeve 2, a retaining ring 12 is provided between two adjacent heat dissipating fins 11, and the retaining ring 12 is sleeved on the outer periphery of the gate channel 1 and fixed on the inner side wall of the sleeve 2, and a gap is left between the inner side edge of the retaining ring 12 and the outer peripheral wall of the gate channel 1.

[0016] In this embodiment, the water inlet pipe 4 is connected to a regulating valve 5, and the valve stem of the regulating valve 5 is coaxially fixedly connected to a gear 10, a temperature sensing tube 7 is embedded in the gate, and the temperature sensing tube 7 is filled with helium. A piston plate 8 is slidably connected to the inside of the temperature sensing tube 7, and a rack 9 is fixedly connected to the piston plate 8, and the rack 9 is meshingly connected to the gear 10.

[0017] In this embodiment, the water inlet pipe 4 is connected to a pressure buffer box 6 , and a diaphragm 13 is fixed inside the pressure buffer box 6 .

[0018] In this embodiment, the inner side edges of the heat dissipation fins 11 are embedded in the outer peripheral wall of the gate channel 1 .

[0019] The principle and advantages of the utility model are as follows: when the cooling device of the flow liquid gate of the horseshoe flame kiln is working, the water pump is started so that the water pump delivers cold water to the inside of the sleeve 2 through the water inlet pipe 4, and the water flows in the space between the sleeve 2 and the gate channel 1, so that the water dissipates heat to the gate channel 1, avoiding damage to the gate channel 1 due to excessive temperature, and then the hot water is discharged through the water outlet pipe 3, thereby avoiding the accident of stopping the kiln and increasing the service life of the gate channel 1.

[0020] The heat dissipation fins 11 on the periphery of the gate channel 1 are used to improve the heat dissipation efficiency, and the baffle ring 12 plays a role in increasing the water flow stroke, thereby achieving the effect of sufficient heat dissipation.

[0021] The temperature sensing cylinder 7 is used to expand or contract the internal helium according to the temperature change of the glass liquid flowing out of the gate, so that the piston plate 8 drives the rack 9 to move up and down. When the temperature of the glass liquid flowing out of the gate increases, the piston plate 8 drives the rack 9 to move up, so that the rack 9 drives the gear 10 to rotate, and then the gear 10 drives the valve stem of the regulating valve 5 to rotate, thereby increasing the flow of the water inlet pipe 4, thereby increasing the water flow inside the sleeve 2 and improving the cooling efficiency. When the temperature of the glass liquid flowing out of the gate decreases, the piston plate 8 drives the rack 9 to move down, so that the rack 9 drives the gear 10 to rotate in the opposite direction, and then the gear 10 drives the valve stem of the regulating valve 5 to rotate in the opposite direction, thereby reducing the flow of the water inlet pipe 4, thereby reducing the water flow inside the sleeve 2 and reducing the cooling efficiency, thereby realizing adaptive adjustment of the cooling efficiency according to the temperature change of the glass liquid flowing out of the gate, and keeping the temperature of the gate channel 1 stable.

[0022] The flow change of the water inlet pipe 4 causes the diaphragm 13 in the pressure buffer box 6 to open or contract accordingly, so that the water pressure in the sleeve 2 changes smoothly, avoiding damage to the gate channel 1 caused by excessively fast pressure changes.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
