[0018] The sealing structure of the glass melting furnace feeding device includes a feeding pool 1, a hanging wall 2, a heat-resistant sealing block A4, a heat-resistant sealing block B5, a slide A7, a slide B8 and a hand winch 12 (see the attached manual). Figure 1 and 2 ).
[0019] A hanging wall 2 is provided above the feeding pool 1; a feeding port 3 is provided between the hanging wall 2 and the feeding pool 1 (see the appendix of the manual). Figure 2 ).
[0020] A heat-resistant sealing block A4 and a heat-resistant sealing block B5 are placed on the feeding port 3; the heat-resistant sealing block A4 and the heat-resistant sealing block B5 are attached to each other (see the appendix of the manual). Figure 1 and 2 ).
[0021] The heat-resistant sealing block A4 and the heat-resistant sealing block B5 are made of heat-resistant materials; the heat-resistant sealing block A4 and the heat-resistant sealing block B5 are bonded together to form an integral structure; the heat-resistant sealing block A4 and the heat-resistant sealing block B5 are provided with an L-shaped feed hole 13 (see the attached manual) Figure 2 and 3 When working, the feeding equipment can transport the materials into the feeding pool 1 through the feeding hole 13.
[0022] The hanging wall 2 above the heat-resistant sealing block A4 and the heat-resistant sealing block B5 is symmetrically slidably mounted with a slide A7 and a slide B8 (see the appendix of the manual). Figure 1 and 2 The lower end of the boom 6 is provided with a T-shaped guide rail 14; the slide A7 and the slide B8 are both provided with guide rollers 15; the slide A7 and the slide B8 are connected to the T-shaped guide rail 14 via the guide rollers 15 (see the appendix of the manual). Figure 2 and 5 During operation, the guide rollers 15 cooperate to push the carriages A7 and B8 to slide back and forth along the T-shaped guide rails 14 .
[0023] Slides A7 and B8 are each equipped with a fixed pulley 9. Heat-resistant sealing blocks A4 and B5 are each equipped with two sets of lifting ropes 11 via lifting rings 10. The lifting ropes 11 on heat-resistant sealing block A4 pass through the corresponding fixed pulleys 9 on slide A7 and connect to a hand winch 12 on slide A7. The lifting ropes 11 on heat-resistant sealing block B5 pass through the corresponding fixed pulleys 9 on slide B8 and connect to the hand winch 12 on slide B8. During operation, the hand winch 12 is cranked to control the vertical movement of heat-resistant sealing blocks A4 and B5, in conjunction with the lifting ropes 11 and fixed pulleys 9.
[0024] A dust collecting cover 16 is fixedly provided on one side of the heat-resistant sealing block A4 and the heat-resistant sealing block B5 (see the attached manual). Figure 1 and 2).
[0025] A dust discharge hole 17 is provided on one side of the dust collection cover 16; an assembly slide shaft 19 is slidably mounted on one side of the dust collection cover 16 through a bracket 18; a dust discharge barrel 20 is fixedly mounted on one end of the assembly slide shaft 19; a buffer spring 21 is sleeved on the assembly slide shaft 19 on one side of the dust discharge barrel 20; a limit ring 22 is provided on the assembly slide shaft 19 on one side of the bracket 18; a positioning ring ridge 23 is provided on one end of the dust discharge barrel 20; a positioning ring groove is provided on the dust collection cover 16 around the dust discharge hole 17; the positioning ring ridge 23 is intermittently connected to the positioning ring groove; the lower end of the dust discharge barrel 20 is connected to the external dust collection device through a flexible connecting pipe 24 (see the attached manual Figure 1 and 4 ).
[0026] The sealing structure of this glass melting furnace charging device ensures that the heat-resistant sealing blocks A4 and B5 seal the majority of the charging port 3 during this process, significantly reducing the possibility of dust spillage. If a small amount of dust does escape into the dust hood 16, it is transported through the dust exhaust cylinder 20 and flexible connecting tube 24 to an external dust collection device. The dust is then recovered and reused, thus resolving the environmental pollution and material waste issues associated with existing glass melting furnace charging processes.
[0027] When the glass melting furnace needs to be inspected, the assembly slide shaft 19 is pulled to overcome the elastic force of the buffer spring 21, thereby driving the dust exhaust cylinder 20 out of contact with the dust hood 16. Then, the hand winch 12 is cranked to control the heat-resistant sealing blocks A4 and B5 to move upward and out of contact with the feeding port 3 in cooperation with the suspension rope 11 and the fixed pulley 9. Subsequently, the heat-resistant sealing blocks A4 and B5 are driven outward by the slides A7 and B8 to clear the feeding port 3, thereby achieving the purpose of avoiding the feeding port 3 and facilitating the inspection of the glass melting furnace.
[0028] The sealing structure of the glass melting furnace feeding device adopts a structural design of a heat-resistant sealing block A4, a heat-resistant sealing block B5 and a dust hood 16. The heat-resistant sealing block A4 and the heat-resistant sealing block B5 block most of the dust inside the feeding pool 1, and under the action of the dust hood 16, it can recover the overflowed dust, thereby solving the problems of environmental pollution and material waste in the existing glass melting furnace feeding process, and is particularly suitable for the needs of glass melting furnace use.
