In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0042] A first aspect of the present invention provides a glass melting furnace regenerator purging device, such as Figure 1 As shown, the purging device 100 includes a spray gun sleeve 10, a spray gun core 20 and a purging gas source, wherein a sealing plug 101 is fixedly provided on the first end of the spray gun sleeve 10, and the sealing plug 101 is adapted to the purging hole on the side wall of the melting furnace heat storage chamber 200, the spray gun core 20 is movably arranged in the spray gun sleeve 10, and the spray gun core 20 can move and rotate relative to the spray gun sleeve 10, the first end of the spray gun core 20 protrudes from the first end of the spray gun sleeve 10 and the sealing plug 101, specifically, the first end of the spray gun core 20 includes a horizontal pipe section 21 and an elbow pipe section 22, and a set angle is formed between the elbow pipe section 22 and the horizontal pipe section 21, the second end of the spray gun core 20 protrudes from the second end of the spray gun sleeve 10, and the second end of the spray gun core 20 is connected to the purging gas source, and the purging gas source is used to supply purging gas to the spray gun core 20.

[0043] The beneficial effects of the glass melting furnace regenerator purging device of the present invention are as follows: Figure 2As shown, since the first end of the spray gun pipe sleeve 10 of the purging device 100 is provided with a sealing plug 101 adapted to the purging hole on the side wall of the melting furnace regenerator 200, the purging device can be always inserted in the purging hole, thereby avoiding the situation where the plug of the purging hole is inserted and pulled out when purging is required, which causes gas leakage; when it is necessary to purge the melting furnace regenerator, the purging gas is supplied to the spray gun pipe core 20 through the purging gas source, so that the purging gas is sprayed into the melting furnace regenerator through the first end of the spray gun pipe core 20 to clean the nodules formed in the melting furnace regenerator. The spray gun tube core 20 can be pulled or pushed to move forward and backward relative to the spray gun tube sleeve 10 during purging and cleaning to adjust the length of the spray gun tube core 20 extending into the melting furnace regenerator 200, thereby improving the cleaning effect and space; further, the spray gun tube core 20 can be rotated during purging and cleaning. Since the first end of the spray gun tube core 20 is provided with an elbow pipe section 22, the spray gun tube core 20 can be rotated during purging and cleaning to make the space area purged by the first end of the spray gun tube core 20 larger, further improving the cleaning effect and efficiency. Therefore, compared with the prior art, the glass melting furnace regenerator purging device of the present invention can greatly reduce the risk of gas leakage, improve the safety of operation, and can also greatly improve the cleaning effect and efficiency.

[0044] Specifically, in this embodiment, the material of the spray gun tube core 20 is heat-resistant stainless steel or heat-resistant ceramic. However, this embodiment does not specifically limit the material of the spray gun tube core. In other optional embodiments, any material with good heat resistance and high hardness and strength can be used.

[0045] Specifically, the glass melting furnace regenerator purging device of the present invention is not only applicable to coal gas furnaces, but also to natural gas furnaces. When the purging device 100 is applied to coal gas furnaces, the purging gas provided by the purging gas source should be steam; when the purging device 100 is applied to natural gas furnaces, the purging gas provided by the purging gas source can be compressed air.

[0046] Furthermore, in order to realize the automated operation of the purge device, preferably, Figure 1As shown, the purge device 100 also includes a control module 30, which includes a three-position five-way solenoid valve 31 and a control unit 32. The three-position five-way solenoid valve 31 is electrically connected to the control unit 32. Specifically, the three-position five-way solenoid valve 31 includes an air inlet, a first air outlet, and a second air outlet, wherein the air inlet is used to communicate with an external air source; accordingly, the first end of the spray gun pipe sleeve 10 is sealed and connected to the spray gun pipe core 20, and the second end of the spray gun pipe sleeve 10 is also sealed and connected to the spray gun pipe core 20. The gun barrel core 20 is sealed and connected, and a piston 201 is fixedly provided in the middle of the spray gun barrel core 20, and the piston 201 is located inside the spray gun barrel sleeve 10. The piston 10 divides the inside of the spray gun barrel sleeve 10 into a first closed chamber 11 and a second closed chamber 12. The first air outlet of the three-position five-way solenoid valve 31 is connected to the first closed chamber 11 through a first pipeline 311, and the second air outlet of the three-position five-way solenoid valve 31 is connected to the second closed chamber 12 through a second pipeline 312. Through this structural design, during operation, when the spray gun tube core 20 needs to move toward the direction close to the second end of the spray gun tube sleeve 10, that is, to reduce the length of the first end of the spray gun tube core 20 extending into the melting furnace heat storage chamber 200, the control unit 32 controls the three-position five-way solenoid valve 31 to open the first gas outlet and close the second gas outlet, and the high-pressure gas introduced from the external gas source is introduced into the first closed chamber 11 through the first pipeline 311. Then, as the pressure in the first closed chamber 11 increases, the pressure inside the first closed chamber 11 will push the piston 201 to move toward the direction close to the second end of the spray gun tube sleeve 10. Since the piston 201 is fixedly connected to the spray gun tube core 20, the piston 201 will drive the spray gun tube core 20 together. It moves backward, that is, toward the direction close to the second end of the spray gun tube sleeve 10, thereby reducing the length of the spray gun tube core 20 extending into the melting furnace heat storage chamber 200; similarly, when it is necessary to increase the length of the first end of the spray gun tube core 20 extending into the melting furnace heat storage chamber 200, the control unit 32 controls the three-position five-way solenoid valve 31 to close the first gas outlet and open the second gas outlet, and the high-pressure gas introduced from the external gas source is introduced into the second closed chamber 12 through the second pipeline 312. The pressure of the second closed chamber 12 will push the piston 201 to move away from the second end of the spray gun tube sleeve 10, and then the piston 201 drives the spray gun tube core 20 to move forward together, increasing the length of the first end of the spray gun tube core 20 extending into the melting furnace heat storage chamber 200. As a preferred embodiment, during operation, the control unit 32 can control the first air outlet and the second air outlet of the three-position five-way solenoid valve 31 to be alternately opened or closed at a set time interval, thereby automatically controlling the spray gun tube core 20 to move back and forth periodically according to a certain rule, thereby effectively improving the degree of automation of the purging operation of the heat storage chamber of the glass melting furnace, greatly reducing the workload of workers, reducing labor costs, and promoting high-quality development of the enterprise.

[0047] Furthermore, in order to accurately control the length of the spray gun tube core 20 extending into the melting furnace regenerator 100, as Figure 1 As shown, in this embodiment, a distance sensor 102 is further provided inside the first end of the spray gun sleeve 10, and the distance sensor 102 is electrically connected to the control unit 32, and the distance sensor 102 is used to detect the distance between it and the piston 201. During operation, when the spray gun tube core 20 is controlled to move forward and backward, the distance sensor 102 can detect the distance and direction of movement of the spray gun tube core 20 (moving away from the distance sensor or moving close to the distance sensor), and the distance sensor 102 transmits the detected information to the control unit 32, and the control unit 32 timely controls the opening and closing of the air inlet, the first air outlet and the second air outlet of the three-position five-way solenoid valve 31 according to the information transmitted by the distance sensor, thereby being able to more accurately control the distance of movement of the spray gun tube core 20, that is, control the length of the first end of the spray gun tube core 20 extending into the melting furnace regenerator 200.

[0048] Further, in some embodiments, the set angle between the horizontal pipe section 21 and the elbow pipe section 22 at the first end of the spray gun pipe core 20 is 90° to 180°. Preferably, in this embodiment, the set angle between the horizontal pipe section 21 and the elbow pipe section 22 is 150°.

[0049] As a preferred embodiment, in order to facilitate the first end of the spray gun tube core 20 to be inserted into the purge hole on the side wall of the furnace regenerator, as shown in FIG. Figure 3 As shown, the purge hole 200a on the side wall of the melting furnace regenerator 200 can be designed as a waist-shaped hole.

[0050] Furthermore, in this embodiment, a rotary joint 202 is provided at the second end of the spray gun tube core 20, and the rotary joint 202 is connected to a purge gas source through a blow pipe (not shown in the figure). The second end of the spray gun tube core 20 is connected to a steam pipe of a steam source through a rotary joint 202, so when the spray gun tube core 20 rotates, the blow pipe will not be driven to rotate together, thereby preventing the blow pipe from being entangled.

[0051] Further, the operation is preferred, in this embodiment, a flow meter is also provided on the air blowing pipeline. Through the setting of the flow meter, when the reading of the flow meter is found to be abnormal during operation, it is determined that the spray gun tube core 20 may be blocked, and then timely discovery and maintenance can be carried out.

[0052] like Figure 2 As shown, another aspect of the present invention further provides a glass melting furnace, which includes a melting furnace heat storage chamber 200. A plurality of purge holes 200a are provided on the side wall of the melting furnace heat storage chamber 200, and the plurality of purge holes 200a are each provided with the glass melting furnace heat storage chamber purge device described above.

[0053] The beneficial effects of the glass melting furnace of the present invention are the same as the beneficial effects of the regenerator purging device of the glass melting furnace described above, so they will not be described in detail here.

[0054] In summary, the glass melting furnace regenerator purging device and glass melting furnace of the present invention can realize the automation of the glass melting furnace regenerator purging operation, while reducing labor costs and improving cleaning efficiency, it also greatly reduces the risk of gas leakage, ensuring a safer, more stable and efficient production of the glass melting furnace. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
