Description

Technical Field

[0001] This utility model relates to the field of kiln grid technology, and in particular to a dredging support for a grid. Background Technology

[0002] The preheating chamber of a glass kiln is used to recover waste heat, preheat fresh air, and supply the air in the preheating chamber to the kiln for combustion. Fresh air is continuously heated and sent into the preheating chamber, and finally enters the combustion chamber of the kiln through the holes of the grid.

[0003] The lattice structure is a key component in glass melting furnaces for heat storage and waste heat recovery. It is mainly composed of refractory bricks and achieves heat exchange through regularly arranged lattice holes. Its design and operation directly affect the thermal efficiency of the melting furnace and the quality of the glass. Moreover, the holes formed inside the lattice structure play a partial role in oxygen supply and can also regulate the temperature of the oxygen inside the furnace.

[0004] The holes in the grid are generally set vertically, which facilitates the rise of hot air into the kiln and allows slag to fall smoothly, preventing the holes from becoming clogged.

[0005] However, the combustion temperatures of the flames inside the kiln vary, with the upper flames being hotter and the lower flames being colder. The combustion produces flue gas, some of which condenses and deposits in the low-temperature zones of the grid. Most of this deposit falls through the grid's openings, but some debris adheres to the grid's openings, causing blockages. This leads to insufficient gas supply to the kiln and also affects heat exchange efficiency.

[0006] Based on this, the present invention designs a grid-type unblocking support to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a grid-type dredging support that allows for remote control of the support for combustion under the grid openings without requiring personnel to approach it. This increases the safety of personnel operation, especially by adding baffles to guide and block the falling slag during grid combustion, thereby changing the direction of the falling high-temperature slag and reducing the chance of burns. This device is operated remotely via an external support rod, which can prevent personnel from being burned by falling slag.

[0008] This utility model is implemented as follows: a lattice-shaped unblocking support, comprising: Telescopic poles, external scaffolding poles, flamethrowers, and fuel hoses; The telescopic rod is a vertically telescopic straight rod, which is vertically fixedly installed on the base plate. The base plate is horizontally set, and multiple rollers are also provided at the bottom of the base plate. The external frame rod is a strut, and the upper end of the external frame rod is rotatably mounted on the telescopic rod through a hinge support. The hinge support shafts at both ends of the external frame rod are horizontally set. The lower end of the outer frame rod is also rotatably mounted with a support plate via a hinge support. The support plate is a flat plate with a flat bottom surface and is covered with anti-slip spikes. A handle is also provided on the outer side of the support plate; The upper end of the telescopic rod is also provided with a baffle, which is an inclined flat plate, and the baffle is fixed to the upper end of the telescopic rod with the outer side higher than the inner side; The flame gun is a vertically arranged closed long tube. The upper end of the flame gun is equipped with a flame nozzle, and the lower end of the flame gun is fixedly installed on a baffle. The axis of the flame gun coincides with that of the telescopic rod. Furthermore, the lower end of the flame gun is equipped with an adapter, the lower end of which extends below the baffle; the lower end of the adapter is sealed to the fuel pipe, which is a flexible hose. A control valve is also provided at the inlet end of the fuel pipe; The outer wall of the flame gun is also provided with multiple marking blocks, which are distributed in a straight line along the vertical direction.

[0009] Furthermore, the upper end of the telescopic rod is the telescopic end, the lower end of the telescopic rod is the fixed end, and the telescopic rod is a hydraulic telescopic rod.

[0010] Furthermore, the handle is a ring-shaped handle, and the outer side of the handle is inclined upward.

[0011] Furthermore, the anti-slip spikes protrude downwards at a height of 1 cm; The length of the external scaffold pole shall not be less than 2 meters.

[0012] Furthermore, the marking block is an outwardly protruding digital sign; The height distance between each of the marked blocks and the top of the flame gun is the different hole depths of the lattice.

[0013] The beneficial effects of this utility model are: 1. This utility model controls the height of the flame gun by controlling the telescopic rod, so that no manual adjustment is required, effectively avoiding the possibility of personnel being directly burned by falling high-temperature slag. At the same time, the addition of a baffle can prevent slag from falling directly on the personnel. The baffle tilted inward pushes all falling objects against the inner wall of the preheating chamber, preventing them from falling towards the outside of the preheating chamber door of the operator, effectively protecting the safety of the personnel. 2. This device is also equipped with an external support rod, which allows the base plate to be swung left and right and the device to be pushed and pulled back and forth, thereby moving the flame gun. This allows the flame gun to spray and burn in different grid holes, thus burning and cleaning different blocked holes. Personnel no longer need to hold the flame gun directly, but can adjust the position of the flame gun remotely through the external support rod, keeping personnel away from grid holes where high-temperature slag may fall, effectively improving personnel safety. 3. The external frame rods of this device also serve to adjust the counterweight of the base plate and telescopic rods, making the device form a more stable support structure. The combination of the support plate and the anti-slip spikes, the support plate presses down to increase the support surface, while the anti-slip spikes can penetrate the furnace ash on the ground and directly stick to the ground, which can form a more stable support effect on the ground through the external frame rods.

Detailed Implementation

[0017] Please see Figures 1 to 4 As shown, this utility model provides a grid-type unblocking support. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0018] In a specific embodiment of the technical solution of this utility model: Includes telescopic pole 1, external frame pole 2, flame gun 3, and fuel pipe 4; Telescopic rod 1 is a vertically telescopic rod, which is vertically fixedly installed on the base plate 11. The base plate 11 is horizontally set. The upper end of telescopic rod 1 is the telescopic end, and the lower end of telescopic rod 1 is the fixed end. Telescopic rod 1 can be a hydraulic telescopic rod or an electric telescopic rod, as long as it can extend and retract stably. The working environment is around 60℃. In this environment, personnel will feel unbearably hot after operating for a long time. However, both hydraulic and electric telescopic rods can operate normally at this temperature. This allows personnel to enter and operate the telescopic rod 1 from the outside immediately, and spray flames to the ventilation holes inside the grid to burn and clear blockages. Because personnel are not in the preheating chamber, the preheating chamber is in a relatively closed state, and the heat inside the furnace will not dissipate to the outside, which can effectively reduce heat loss and effectively avoid a sudden drop in the temperature inside the furnace.

[0019] Personnel can observe the combustion process from a cooler area near the preheating chamber door, away from the grid structure, which is safer.

[0020] Furthermore, multiple rollers 12 are installed at the bottom of the base plate 11. The base plate 11 rolls on the ground via the rollers 12, which are omnidirectional wheels to facilitate adjustment of the orientation structure. The base plate 11 needs to be larger and heavier to ensure the overall structural support stability. Generally, the base plate 11 is a 1-square-meter steel plate and its weight needs to reach more than 5 kg to ensure the stability of the center of gravity.

[0021] The outer frame rod 2 is a support rod. The upper end of the outer frame rod 2 is rotatably mounted on the telescopic rod 1 through a hinge support. The hinge support shafts at both ends of the outer frame rod 2 are set horizontally, so that the elevation angle of the outer frame rod 2 can only be adjusted in the same vertical plane. This ensures that the outer frame rod 2 is stably supported in the same vertical plane and avoids left and right rotation. Therefore, the entire base plate 11 and the telescopic rod 1 can be moved left and right together by moving the outer frame rod 2 left and right, which is convenient to operate. The outer frame rod 2 is fixedly connected to the telescopic rod 1 by a ring hoop, which can be welded or locked with a pipe hoop.

[0022] The lower end of the outer frame rod 2 is also rotatably mounted with a support plate 21 through a hinge support. The support plate 21 is a flat plate with a flat bottom surface. The bottom of the support plate 21 is also covered with anti-slip spikes 24, and the anti-slip spikes protrude downward at the bottom of the support plate 21. The anti-slip spikes 24 protrude downwards to a height of 1cm. In the preheating chamber, a small amount of furnace ash will fall down and form an ash layer. When it is fluffy, it will be about 1cm thick. When the support plate 21 of this device is pressed down, it may slip on the ash pad. The anti-slip spikes 24 are nailed into the ground at the bottom of the preheating chamber to form a stable grip, ensuring that the support plate 21 is pressed down stably and provides support for the telescopic rod 1. The length of the outer frame pole 2 is not less than 2 meters, and the material is steel pipe, which is easy to hold and operate, and provides sufficient counterweight and support. When operating, it can be lifted up. The weight of the outer frame pole 2 is generally less than 5 kg, and it is used to support the telescopic pole 1. The weight of the telescopic pole 1 is also not large, generally around 2 kg. The overall weight of this device is relatively light, which makes it easy for personnel to push, pull and swing left and right to move and position the device. It is mainly used to transport natural gas fuel to the holes in the grid for combustion.

[0023] A handle 23 is also provided on the outer side of the support plate 21. The handle 23 is a ring handle, and the outer side of the handle 23 is inclined upwards, such as... Figure 2 As shown, it is easy for people to lift and pull, and avoids people grabbing the ground when they grab the handle 23. It is also convenient for people to hold and operate, and it is easier to swing left and right and push and pull. A baffle 31 is also provided at the upper end of the telescopic rod 1. The baffle 31 is a flat plate that is inclined and is fixed to the upper end of the telescopic rod 1 with the outer side higher than the inner side. The flame gun 3 is a vertically arranged enclosed long tube. The flame nozzle is installed at the upper end of the flame gun 3, and the lower end of the flame gun 3 is fixedly installed on the baffle 31. The axis of the flame gun 3 coincides with that of the telescopic rod 1. The flame gun 3 is locked to the baffle 31 by multiple bolts, so it can be easily disassembled for inspection and maintenance. Especially when the nozzle is affected by melted blockage, it is convenient to clean the flame gun 3.

[0024] Furthermore, an adapter 33 is provided at the lower end of the flame gun 3. The adapter 33 is a quick-connect connector, and the lower end of the adapter 33 extends below the baffle 31. The lower end of the adapter 33 is sealed to the fuel pipe 4, which is a flexible hose. A control valve 41 is also provided at the inlet end of the fuel pipe 4; Multiple marker blocks 32 are also set on the outer wall of the flame gun 3, and the multiple marker blocks 32 are distributed in a straight line along the vertical direction.

[0025] Marker block 32 is a protruding number sign; The height distance between each marker block 32 and the top of the flame gun 3 is the different hole depths of the grid. That is, by using the marker block 32, it is easy to know how deep the flame gun 3 has penetrated into the grid, and thus know the specific burning depth of the flame gun 3. It can also prevent the flame gun 3 from completely penetrating the holes of the grid. In other words, the bottommost marker block 32 of the flame gun 3 is the maximum depth of the grid.

[0026] This allows personnel to accurately observe the extension height of the telescopic pole 1.

[0027] The controller of telescopic rod 1 needs to be set at a remote location and can be bound together with control valve 41 for easy synchronous operation by personnel. Both the controller and control valve 41 are wrapped with flexible pipelines, and the control method is convenient, simply by switching them on and off.

[0028] When using this utility model, the device is placed below the blocked hole of the grid body, and then the telescopic rod 1 is raised and lowered. The height position of the flame gun 3 can be viewed through the marker block 32. Then the outer frame rod 2 is lowered, the support plate 21 is pressed on the furnace ash on the ground, and the anti-slip spikes 24 are firmly stuck to the hard brick surface to ensure stability.

[0029] Then, control valve 41 is opened to spray natural gas fuel, and the flame gun 3 is ignited through the igniter of the wire to burn the blocked grid.

[0030] The slag blocks solidify upon cooling and will fall off when burned at high temperatures again, thus cleaning the grid. In general, multiple grids will be blocked. At this time, the device does not need to shut off the flame. First, control the shortening telescopic rod 1 to withdraw the flame gun 3 from the cleaned grid holes.

[0031] Then, by directly holding the handle 23, lift the outer frame rod 2, which can be moved left and right, so that the base plate 11 and the telescopic rod 1 can also move along with it until the flame gun 3 is aimed at another blocked grid hole. Extend the telescopic rod 1 again and insert the flame gun 3 into the hole to burn and clear the blockage. The personnel operation distance is far, and there is no need for personnel to observe at close range. The falling debris will bounce inward through the baffle 31, effectively ensuring personnel safety.

[0032] The inner side of this device refers to the inner wall of the preheating room, and the outer side refers to the door side for personnel to enter. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this utility model and simplifying the description.
