Description

Technical Field

[0001] This invention relates to the field of substrate glass production technology, and more specifically to an automatic unloading device for substrate glass furnace charge tanks. Background Technology

[0002] The main raw materials for substrate glass include silica sand, alumina, boric acid, carbonates, and other auxiliary materials. The production of substrate glass is a complex and delicate process, with main steps including raw material preparation, melting, forming, heat treatment, cutting and processing, and post-processing.

[0003] During the production of substrate glass, different types and quantities of raw materials need to be weighed and mixed evenly according to the production formula to ensure uniform dispersion and distribution of the raw materials. Then, the mixed raw materials are fed into the glass furnace for melting using a feeding mechanism.

[0004] Since these raw materials are mostly in the form of powder or fine particles, they are easily airborne. In addition, the materials have a long falling path in the smelting furnace, which easily generates dust. The generation and spread of dust require additional control measures to prevent them from affecting the environment and workers' health, which increases the difficulty and cost of control. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic unloading device for substrate glass furnace charge tanks to solve the technical problem of dust flying during the unloading process in the prior art.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] An automatic unloading device for a substrate glass furnace charge tank includes a stainless steel hopper, the top of which is connected to a discharge pipe, and further includes:

[0008] An automatic unloading assembly includes a valve core push rod, an upper flange unloading pipe, and a tank body. A fixed crossbar is horizontally arranged inside the unloading pipe, and the valve core push rod is fixed to the top of the fixed crossbar. The top of the valve core push rod is higher than the top of the unloading pipe. The bottom of the tank body is funnel-shaped, and a conical valve core assembly is fitted inside the lower part of the tank body, fitting snugly against the inner wall of the tank body. An opening is provided at the top of the tank body, and the opening end cap is... The hopper has a handle and a cover. A lower flange discharge pipe is fixed to the top of the discharge pipe. An upper flange discharge pipe is symmetrically located directly above the lower flange discharge pipe. An elastic lifting component is provided between the flanges of the lower and upper flange discharge pipes. A flexible dustproof component is provided between the discharge pipes of the lower and upper flange discharge pipes. A rubber sealing gasket is provided on the side of the upper flange discharge pipe away from the lower flange discharge pipe. The rubber sealing gasket is matched with the discharge port of the hopper body.

[0009] As a further aspect of the present invention: the elastic lifting assembly includes a compression spring and guide rods. Several guide rods are circumferentially fixed at the bottom of the flange of the upper flange unloading pipe. The bottom of each guide rod passes through the lower flange unloading pipe and is slidably connected to it. A compression spring is sleeved on the outside of each guide rod. One end of the compression spring is connected to the flange of the upper flange unloading pipe, and the other end is connected to the flange of the lower flange unloading pipe. Several equal-height limiting screws are circumferentially distributed at the top of the flange of the lower flange unloading pipe. The limiting screws are movably connected to the flange of the lower flange unloading pipe, and the limiting screws limit the descent height of the upper flange unloading pipe.

[0010] As a further embodiment of the present invention: the flexible dustproof component includes a lower clamp, a canvas tube, and an upper clamp. Both the lower clamp and the upper clamp consist of two semi-circular clamps, and both ends of the two semi-circular clamps are fastened with screws. One end of the canvas tube is fitted onto the outside of the upper flange unloading pipe, and the other end is fitted onto the outside of the lower flange unloading pipe. The upper clamp is fitted onto the outside of the canvas tube and the upper flange unloading pipe to fix the upper end of the canvas tube, and the lower clamp is fitted onto the outside of the canvas tube and the lower flange unloading pipe to fix the lower end of the canvas tube.

[0011] As a further embodiment of the present invention: the outer circumferential side of the lower flange unloading pipe is welded with a downward flange clamp, the upper clamp is sleeved on the outer side of the upper flange unloading pipe and engages with the upward flange clamp, the outer circumferential side of the upper flange unloading pipe is welded with an upward flange clamp, and the lower clamp is sleeved on the outer side of the lower flange unloading pipe and engages with the downward flange clamp.

[0012] As a further aspect of the present invention: a dividing cone is provided at the top of the fixed crossbar, and the top of the dividing cone is a pointed part.

[0013] As a further aspect of the present invention: a number of support legs are distributed between the bottom of the lower flange unloading pipe and the stainless steel hopper for support.

[0014] As a further aspect of the present invention: the lower half of each limiting screw is screw-shaped, and the limiting screws are all threadedly connected to the unloading pipe of the lower flange.

[0015] As a further aspect of the present invention, the outer wall of the material tank body is provided with no fewer than three lifting lugs.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, the material tank body is placed on top of the upper flange unloading pipe. The upper flange unloading pipe can be lowered, causing the valve core push rod to continuously push up the conical valve core assembly inside the material tank body. The conical valve core assembly creates a distance between itself and the inner wall of the material tank body, thereby automatically feeding the raw material inside the material tank body into the stainless steel hopper. A flexible dustproof component is installed between the material pipe of the lower flange unloading pipe and the material pipe of the upper flange unloading pipe, so that the dustproof effect between the upper flange unloading pipe and the lower flange unloading pipe is not affected when the upper flange unloading pipe is lowered. A rubber sealing gasket is installed on the side of the upper flange unloading pipe away from the lower flange unloading pipe. When the material tank body is placed on top of the rubber sealing gasket, a seal is achieved, preventing the raw material from flying out from the contact gap, thus affecting the anti-flying effect.

[0018] 2. The present invention provides a dividing cone at the top of the fixed crossbar. The top of the dividing cone is pointed. When the material falls on the top of the dividing cone, it is dispersed, thus avoiding the accumulation of raw materials that clumped together and caused blockage in the unloading pipe of the hopper.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1-6As shown, an automatic unloading device for a substrate glass furnace charge tank includes a stainless steel hopper 1 and an automatic unloading assembly. The stainless steel hopper 1 has an opening at its top, and a charge unloading pipe 2 is fixedly connected to the opening. The automatic unloading assembly includes a valve core push rod 9, an upper flange charge unloading pipe 14, and a charge tank body 17. A fixed crossbar 20 is horizontally fixed inside the charge unloading pipe 2. The valve core push rod 9 is fixed at the top middle position of the fixed crossbar 20, and the top height of the valve core push rod 9 is higher than the top height of the charge unloading pipe 2. The bottom of the charge tank body 17 is funnel-shaped, and the lower end of the charge tank body 17 is fitted with... A conical valve core assembly 16 is provided, which fits against the inner wall of the tank body 17. The valve core push rod 9 is used to lift the conical valve core assembly 16 inside the tank body 17. An opening is provided at the top of the tank body 17, and a cover with a handle 19 is provided at the opening end of the tank body 17. The cover with a handle 19 is designed to prevent raw materials from flying out of the opening at the top of the tank body 17 during feeding. A lower flange discharge pipe 3 is fixed to the top of the hopper discharge pipe 2. Both the lower flange discharge pipe 3 and the upper flange discharge pipe 14 are composed of a pipe and a flange with the same inner diameter. The pipe is located on one side of the flange, and the inner diameter of the pipe is the same as that of the corresponding flange. The inner diameters are aligned, and the material pipes of the lower flange unloading pipe 3 and the upper flange unloading pipe 14 are arranged opposite each other. The upper flange unloading pipe 14 is symmetrically located directly above the lower flange unloading pipe 3. An elastic lifting component is provided between the flanges of the lower flange unloading pipe 3 and the upper flange unloading pipe 14. When the tank body 17 is placed on top of the upper flange unloading pipe 14, the upper flange unloading pipe 14 can be lowered, causing the valve core push rod 9 to continuously push up the conical valve core assembly 16 inside the tank body 17. The conical valve core assembly 16 creates a distance between itself and the inner wall of the tank body 17, thereby allowing the raw material inside the tank body 17 to flow freely. The material is added to the stainless steel silo 1. A flexible dustproof component is installed between the material pipe of the lower flange unloading pipe 3 and the material pipe of the upper flange unloading pipe 14. This ensures that the dustproof effect between the upper flange unloading pipe 14 and the lower flange unloading pipe 3 is not affected when the upper flange unloading pipe 14 descends. A rubber sealing gasket 15 is installed on the side of the upper flange unloading pipe 14 away from the lower flange unloading pipe 3. When the material tank body 17 is placed on top of the rubber sealing gasket 15, a seal is achieved, preventing the material from flying out from the contact gap and thus affecting the dustproof effect. No additional control measures are required for environmental management, reducing the control difficulty and cost.

[0029] In some specific implementation plans, such as Figure 2As shown, to facilitate the placement of the tank body 17 on top of the upper flange discharge pipe 14, the valve core lifting rod 9 can lift the conical valve core assembly 16 inside the tank body 17. The elastic lifting assembly includes a compression spring 6 and a guide rod 7. Several guide rods 7 are circumferentially fixed at the bottom of the flange of the upper flange discharge pipe 14. The bottom of each guide rod 7 passes through the lower flange discharge pipe 3 and is slidably connected to the lower flange discharge pipe 3. The guide rod 7 has a limiting function to ensure the parallel compression of the upper flange discharge pipe 14. A compression spring 6 is sleeved on the outside of each guide rod 7. One end is connected to the flange of the upper flange unloading pipe 14, and the other end is connected to the flange of the lower flange unloading pipe 3. When the material tank body 17 leaves, the compression spring 6 can drive the upper flange unloading pipe 14 to reset, which is convenient for the next feeding. Several limit screws 8 of equal height are arranged circumferentially on the top of the flange of the lower flange unloading pipe 3. The limit screws 8 are all connected to the flange of the lower flange unloading pipe 3 in a movable fit. The limit screws 8 limit the descent height of the upper flange unloading pipe 14, ensuring that the valve core top rod 9 can open the conical valve core assembly 16 normally.

[0030] In some specific implementation plans, such as Figure 4 As shown, to ensure that the dustproof performance between the lower flange unloading pipe 3 and the upper flange unloading pipe 14 is not affected when the upper flange unloading pipe 14 moves, the flexible dustproof assembly includes a lower clamp 10, a canvas sleeve 11, and an upper clamp 12. Both the lower clamp 10 and the upper clamp 12 consist of two semi-circular clamps, with both ends of the semi-circular clamps fastened with screws. One end of the canvas sleeve 11 is fitted onto the outside of the upper flange unloading pipe 14, and the other end is fitted onto the outside of the lower flange unloading pipe 3. The upper clamp 12 is fitted onto the outside of the canvas sleeve 11 and the upper flange unloading pipe 14 for fixation. At the upper end of the canvas cylinder 11, the lower clamp 10 is fitted on the outside of the pipes of the canvas cylinder 11 and the lower flange discharge pipe 3 to fix the lower end of the canvas cylinder 11. When the gas containing particles passes through the canvas cylinder 11, the powder particles will be captured by the canvas cylinder 11, while allowing the gas to pass smoothly into the outside. While filtering out the powder, it can also release some airflow to prevent the internal airflow from being unable to be released. The handle cover 19 is lifted up. The canvas cylinder 11 is detachably connected to the pipes of the upper flange discharge pipe 14 and the lower flange discharge pipe 3, which facilitates the replacement or cleaning of the canvas cylinder 11 in the future.

[0031] In some specific implementation plans, such as Figure 4As shown, in order to enhance the stability of the canvas tube 11, a downward flanged snap 4 is welded to the outer circumference of the lower flange unloading pipe 3. The upper clamp 12 is fitted onto the outer side of the upper flange unloading pipe 14 and engages with the upper flanged snap 13. The upper flanged snap 13 is welded to the outer circumference of the upper flange unloading pipe 14. The lower clamp 10 is fitted onto the outer side of the lower flange unloading pipe 3 and engages with the lower flanged snap 4. When fixing the canvas tube 11, the upper clamp 12 and the lower clamp 10 engage with the upper flanged snap 13 and the lower flanged snap 4 respectively, to prevent the upper clamp 12 or the lower clamp 10 from slipping off when the upper flange unloading pipe 14 moves up and down, which would cause gaps at the connection of the two ends of the canvas tube 11 and result in poor anti-flying effect. The setting of the upper flanged snap 13 and the lower flanged snap 4 not only enhances the stability of the canvas tube 11 but also improves the dustproof performance of the overall device.

[0032] In some specific implementation plans, such as Figure 5 As shown, in order to facilitate the dispersion of the lumpy raw materials falling inside the material tank body 17, a dividing cone 21 is provided at the top of the fixed crossbar 20. The top of the dividing cone 21 is pointed. When the material falls on the top of the dividing cone 21, it is dispersed, thus preventing the lumpy raw materials from accumulating inside the material hopper discharge pipe 2 and causing material blockage.

[0033] In some specific implementation plans, such as Figure 1 As shown, in order to enhance the load-bearing strength of the lower flange unloading pipe 3, several support legs 5 are distributed between the bottom of the lower flange unloading pipe 3 and the stainless steel hopper 1 to prevent the material inside the tank body 17 from being too heavy, which would cause the lower flange unloading pipe 3 to tilt and be damaged.

[0034] In some specific implementations, in order to facilitate the adjustment of the final descent height of the upper flange unloading pipe 14, the lower half of each limit screw 8 is screw-shaped (not shown in the figure). The limit screws 8 are all threadedly connected to the lower flange unloading pipe 3. Tightening the limit screws 8 can adjust the relative height between the limit screws 8 and the lower flange unloading pipe 3, thereby changing the final descent height of the upper flange unloading pipe 14.

[0035] In some specific implementation plans, such as Figure 1 As shown, in order to facilitate the lifting of the material tank body 17, no fewer than three lifting lugs 18 are provided on the outer wall of the material tank body 17. The lifting lugs 18 are hooked with steel wire ropes, and the material tank body 17 can be moved in conjunction with the crane.

[0036] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0037] Hanging lug 18 on a wire rope, the material tank body 17 is lifted using a crane and wire rope and placed on top of the rubber sealing gasket 15. Due to the gravity of the material tank body 17, the upper flange discharge pipe 14 moves downward, and the guide rod 7 slides relative to the flange of the lower flange discharge pipe 3. At the same time, the compression spring 6 deforms and compresses, descending until the flange of the upper flange discharge pipe 14 abuts against the top of the limit screw 8. During the movement, the valve core push rod 9 continuously pushes up the conical valve core assembly 16 inside the material tank body 17, and the raw material inside the material tank body 17 is automatically added to the stainless steel silo 1. A rubber sealing gasket 15 is provided at the top of the discharge pipe 14, and the bottom of the material tank body 17 is sealed by fitting with the rubber sealing gasket 15. At the same time, a cover 19 with a handle is provided at the top of the material tank body 17. When the glass raw material inside the material tank body 17 is discharged, the dust will not fly out of the opening at the top of the material tank body 17 in large quantities and pollute the environment. Furthermore, a canvas tube 11 is detachably connected between the upper flange discharge pipe 14 and the lower flange discharge pipe 3 through the lower clamp 10 and the upper clamp 12. The canvas tube 11 can filter the flying raw material particles inside. Because it is detachably connected, the canvas tube 11 can be cleaned or replaced from time to time.

[0038] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
