Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of defoaming agent addition, in particular to an automatic telescopic device for a kiln spray gun for controlling and protecting a defoaming agent spray gun when a kiln is switched. Background Art
[0002] During the glass melting process, a large amount of foam will be generated in the glass liquid because of the introduction of air and moisture into the gaps between the raw materials and the generation of gas by chemical reactions between the raw materials. The existence of this foam layer is very unfavorable to the production of the kiln. The general practice is to spray defoaming agents into the kiln to eliminate the foam layer. At present, the full oxygen combustion kiln generally uses a method of opening a hole on the breast wall on one side of the furnace body and adding a spray gun to continuously spray defoaming agents; the air combustion spray gun will add a spray gun to the regenerator or small furnace on both sides of the furnace body to spray defoaming agents.
[0003] Because the air combustion kiln needs to change the direction of air and fuel addition regularly during the production process, the operation of changing the direction is called "reversing" on the kiln, so the defoamer spray gun also needs to follow the reversing operation and spray the defoamer intermittently. During the reversing period, because the spray gun is still inside the kiln at 1600℃, although there is a protective device outside the spray gun, because there is no material cooling, the spray gun is in a "dry burning" state for a long time. The existence of this state will cause a small amount of residual material at the spray gun mouth to carbonize at high temperature, which will block the spray gun after a long time, causing the spray effect to deteriorate and thus affect the use of the defoamer; on the other hand, it will greatly reduce the service life of the spray gun, and will also cause poor atomization of the spray gun and affect the use of the defoamer. In view of the above-mentioned deficiencies of the equipment, a device is needed to move the spray gun out of the high-temperature area of the furnace during the reversing period to protect the spray gun and ensure the use of the defoamer. Utility Model Content
[0004] In order to solve the problems of the prior art, the utility model provides an automatic telescopic device for a spray gun, which operates in conjunction with a kiln reversing system.

[0013] Explanation of the reference numerals: spray gun hole 1, spray gun 2, telescopic cylinder 3, spray gun guide rail 4, spray gun bracket 5, reversing controller 6, feed hose 7, baffle 8, rotating cylinder 9 and rotating controller 10. DETAILED DESCRIPTION
[0014] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.
[0015] The working principle of an automatic extension and retraction device for a kiln spray gun is: it automatically extends and retracts according to a kiln reversing signal, and when there is no need to spray a defoaming agent, the device can automatically withdraw the spray gun from the kiln.
[0016] The automatic telescopic device of the kiln spray gun comprises a spray gun hole 1, a spray gun 2, a telescopic cylinder 3, a spray gun guide rail 4, a spray gun bracket 5, a reversing controller 6, a feed hose 7, a baffle 8, a rotating cylinder 9 and a rotating controller 10.
[0017] The spray gun hole 1 is located on the kiln, that is, a through hole is provided on the side wall of the kiln, and the through hole is the spray gun hole 1 .
[0018] In order to ensure that the spray gun hole 1 is sealed when not in use, a rotating cylinder 9 is provided in front of the spray gun hole 1, and a baffle 8 is installed in front of the rotating cylinder 9. The rotating cylinder 9 is controlled by a rotating controller 10 to indirectly control the rotation angle of the baffle 8. It should be noted that the rotating cylinder 9 can be installed on the kiln through an existing rotating cylinder fixing frame, and the baffle 8 is fixedly installed on the rotating shaft of the rotating cylinder 9. The rotating controller 10 controls the rotation angle of the rotating cylinder 9, and simply controls the rotation angle of the baffle 8, thereby indirectly achieving the effect of exposing or covering the spray gun hole 1.
[0019] A spray gun guide rail 4 is installed on the spray gun bracket 5, and a telescopic cylinder 3 is installed on the spray gun guide rail 4. The rear part of the telescopic cylinder 3 is connected to the reversing controller 6, and the reversing controller 6 can control the forward or backward process of the telescopic cylinder 3; a spray gun 2 is installed at the front part of the telescopic cylinder 3, and the spray gun 2 is connected to an external defoaming agent tank via a feed hose 7; a check valve and a filter are also arranged between the spray gun 2 and the defoaming agent tank.
[0020] It should be noted that the spray gun bracket 5 is a frame body with a platform welded by steel structure, and the platform of the spray gun bracket 5 is installed with a spray gun guide rail 4 by bolts, and the spray gun guide rail 4 is a guide rail currently available on the market. A telescopic cylinder 3 is slidably installed on the spray gun guide rail 4, and the telescopic cylinder 3 is a telescopic cylinder currently available on the market. A spray gun 2 is fixedly installed on the telescopic shaft of the telescopic cylinder 3, and the nozzle of the spray gun 2 is aligned with the spray gun hole 1. The feed port of the spray gun 2 is connected to the external defoamer tank via a feed hose 7. In order to ensure the normal operation of the spray gun 2, a check valve and a filter are also provided between the spray gun 2 and the defoamer tank. The check valve can prevent the defoamer from backflowing when the spray gun 2 sprays liquid, and the filter can filter impurities in the defoamer to prevent the spray gun 2 from being blocked.
[0021] Operation method of automatic telescopic device for kiln spray gun:
[0022] When the kiln needs to spray defoaming agent with the spray gun 2 during the reversing process, the rotary controller 10 receives the signal and controls the rotary cylinder 9 to drive the baffle 8 to rotate, and the spray gun hole 1 becomes open. After the spray gun hole 1 is opened, the reversing controller 6 sends a signal, and the telescopic cylinder 3 is activated to push the spray gun 2 installed on the spray gun guide rail 4 forward, and push the spray gun 2 into the kiln for defoaming agent spraying and feeding. When the defoaming agent needs to be stopped during the reversing process, the above action is performed in reverse to pull out the spray gun 2 and block the spray gun hole 1.
[0023] In summary, the automatic telescopic device for the kiln spray gun is provided with a spray gun bracket at the spray gun, and a telescopic device is installed on the spray gun bracket (the telescopic device can be in the form of a cylinder, a hydraulic cylinder, an electric screw, an electric camshaft, etc. to realize the telescopic movement of the spray gun). When the spray gun stops spraying, the controller sends a signal, and the spray gun is pulled out of the kiln body under the action of the telescopic device. During the period when the spray gun is pulled out, because the spray gun is still relatively close to the high-temperature furnace body, the spray gun is continuously protected by cooling water and air to continuously protect the spray gun. After the spray gun is pulled out, another spray gun hole blocking control device rotates the relevant furnace body baffle to the spray gun opening to block the spray gun mouth to prevent the flame in the furnace body from escaping along the spray gun mouth, causing safety hazards and fuel waste. When spraying is required, the blocking device and the spray gun telescopic device act in reverse to open the spray gun hole and insert the spray gun into the furnace body. After using this system, the spray gun is pulled out of the kiln when not spraying materials. The spray gun is in a relatively good environment, the atomization effect of the spray gun is more guaranteed and its service life is greatly extended. The atomization condition of the defoaming agent is also relatively stable, which ultimately provides good basic conditions for the stable operation of the kiln.
