Description

Technical Field

[0001] The present invention relates to the technical field of glass melting furnaces, and particularly to an automatic feeding system for a glass melting furnace. Background Art

[0002] With the rising prices of traditional fossil raw materials and the increasingly strict national emission requirements, electrically assisted melting and fully electric melting glass melting furnaces are becoming more and more popular. The daily melting capacity of some fully electric melting glass melting furnaces is relatively small and they adopt a cold top structure. Therefore, the batching process is currently completed manually, that is, the feeding worker opens the feeding door at the top of the feeding chamber and shovels the batch into the glass melting furnace through the feeding door. However, manual feeding has several disadvantages. One is the increase in labor costs, that is, the increase in production costs. The second is that the feeding amount of manual feeding cannot be accurately controlled, which easily causes uneven feeding. The third is that the feeding door needs to be opened during the manual feeding process, and dust is likely to escape from the feeding chamber, causing greater pollution to the production workshop and being extremely harmful to the physical health of the feeding workers. Summary of the Invention

[0003] Aiming at the above defects, the purpose of the present invention is to provide an automatic feeding system for a glass melting furnace, which can reduce labor costs, improve feeding stability, and improve the production workshop environment.

[0004] The present invention provides an automatic feeding system for a glass melting furnace. The feeding chamber is located above the glass melting furnace and is connected to the glass melting furnace. It includes an upper belt conveyor installed outside the top wall of the feeding chamber and a lower belt conveyor arranged in the feeding chamber. The two are connected through a feeding chute, and the feeding chute penetrates the top wall of the feeding chamber. A support frame is provided at the top of the glass melting furnace, a turntable is provided at the center of the support frame, and a track is installed on the top of the turntable. A movable trolley capable of moving along the track is provided at each of the bottom ends of the lower belt conveyor. A through hole is provided in the movable trolley. The batch falls onto the liquid surface of the glass melting furnace through the upper belt conveyor, the feeding chute, the lower belt conveyor, and the through hole.

[0005] Preferably, it further includes a controller, and the controller is respectively connected to the upper belt conveyor, the lower belt conveyor, the movable trolley, and the turntable.

[0006] Preferably, it further includes a temperature sensor for detecting the liquid surface temperature of the glass melting furnace, and the temperature sensor is connected to the controller.

[0007] Preferably, it further includes a liquid level gauge for detecting the liquid level of the glass melting furnace, and the liquid level gauge is connected to the controller.

[0008] Preferably, the belt wheels provided at both ends of the lower belt conveyor can rotate clockwise or counterclockwise.

[0009] The advantages of the present invention are as follows. By setting up the upper belt conveyor, lower belt conveyor, track and turntable, 360° dead - angle - free feeding into the glass melting furnace is achieved, which can greatly save the input of labor costs. During the feeding process, targeted uniform and stable feeding can be carried out according to the temperature and liquid level data of the melting furnace, which is very beneficial to improving the yield of glass products. At the same time, the feeding chute passing through the top wall of the feeding chamber helps to ensure that the feeding chamber is a closed structure. During the feeding process, there is no need to open the feeding door, reducing the escape of dust and greatly improving the workshop production environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following further details the specific embodiments of the present invention in conjunction with the drawings. These embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

[0026] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] As Figure 1 and Figure 3 shown, the cross-sections of the existing glass melting furnaces 2 are all circular. The charging chamber 1 is located above the glass melting furnace 2 and is in communication with the glass melting furnace 2. The charging door 11 of the charging chamber 1 is arranged on one side of the top wall of the charging chamber 1. When the charging door 11 is in the closed state, the charging chamber 1 and the glass melting furnace 2 are in a sealed structure. Currently, when the charging workers perform manual charging, they need to open the charging door 11 and shovel the batch material into the glass melting furnace 2 through the charging door 11.

[0029] The present invention provides an automatic charging system for a glass melting furnace to solve the problems existing in manual charging. As Figure 1 and Figure 2 shown, the system includes an upper belt conveyor 4 installed outside the top wall of the charging chamber 1 and a lower belt conveyor 6 arranged inside the charging chamber 1. The two are connected through a feeding chute 5. The feeding chute 5 penetrates the top wall of the charging chamber 1. Its upper end is connected to the end of the upper belt conveyor 4 close to the center of the glass melting furnace 2, and its lower end is connected to the belt surface of the lower belt conveyor 6.

[0030] As Figure 1 and Figure 3 ​As shown in the figure, a cross-shaped support frame 21 is provided at the top of the glass melting furnace 2. The center of the support frame 21 is coaxial with the center of the glass melting furnace 2. A turntable 9 is provided at the center of the support frame 21. Specifically, the turntable 9 includes a rotation driving device and a disk body connected to the rotating shaft of the rotation driving device. A track 8 is installed on the top of the disk body. The track 8 extends along the radial direction of the feeding chamber 1. At the bottom of both ends of the lower belt conveyor 5, a moving trolley 7 that can move along the track 8 is provided. The moving trolley 7 includes a plurality of wheels and a driving device for driving the wheels to rotate. A through hole 71 extending in the vertical direction is also provided in the moving trolley 7.

[0031] As Figure 1 shown, when the automatic feeding system of the glass melting furnace of the present invention is working, the batch material 3 falls above the liquid surface of the glass melting furnace 2 through the upper belt conveyor 4, the feeding chute 5, the lower belt conveyor 6 and the through hole 71, forming a cold top covering material pile. The cold top covering material pile can effectively avoid the loss of volatile components during the glass melting process. During this process, the lower belt conveyor 6 can not only move horizontally along the track 8, but also rotate 360° under the drive of the turntable 9, thereby covering the entire liquid surface of the glass melting furnace 2; at the same time, the belt wheels provided at both ends of the lower belt conveyor 6 can rotate in the clockwise or counterclockwise direction, so that the batch material 3 falling on the belt of the lower belt conveyor 6 through the feeding chute 5 can move to the right or left with the rotation of the belt wheels, further realizing uniform feeding.

[0032] Specifically, the automatic feeding system of the glass melting furnace of the present invention further includes a controller, a temperature sensor for detecting the liquid surface temperature of the glass melting furnace 2, and a liquid level gauge for detecting the liquid level of the glass melting furnace 2. The controller is respectively connected to the upper belt conveyor 4, the lower belt conveyor 6, the driving device of the moving trolley 7, the rotation driving device of the turntable 9, the temperature sensor and the liquid level gauge.

[0033] The temperature sensor is preferably an infrared thermometer. When the infrared thermometer detects local high temperature on the liquid surface, it means that the melting of the material in the melting furnace is uneven. At this time, the controller can achieve fixed-point feeding at the high temperature point by controlling the turntable 9, the moving trolley 7 and / or the lower belt conveyor 6.

[0034] The controller can also automatically adjust the rotation speed of the belt wheels of the lower belt conveyor 6 according to the data of the liquid level gauge, and then change the feeding speed of the lower belt conveyor 6 to ensure the stable discharge amount of the glass melting furnace 2.

[0035] The controller can also control the upper belt conveyor 1 and / or the lower belt conveyor 2 according to the melting situation of the cold top covering material pile to achieve continuous feeding and intermittent feeding.

[0036] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
