Description

Technical Field

[0001] The utility model relates to the technical field of flame-blocking bricks in the production of rolled glass, in particular to a flame-blocking brick and also to a flame-blocking device for a rolled glass overflow outlet using the flame-blocking brick. Background Art

[0002] In the production process of rolled glass, the temperature of the overflow glass liquid is regulated by burning side fires and installing flame-blocking and heat-insulating devices. The disadvantages of the common flame-blocking devices are: 1) The flame-blocking brick body is not tightly fitted with the overflow arch, which is easy to penetrate fire; 2) Since the volatile components are easily accumulated in the gap between the flame-blocking brick and the overflow, when they accumulate to a certain amount, they are easy to fall on the glass plate to form falling defects; 3) The distance from the insulation brick at the overflow is too large, the flame-blocking effect of the overflow is poor, and defects such as cold glass, condensation lines and crystallization are easy to appear; 4) The steel parts of the hanging brick body are easily burned when exposed to high temperature for a long time, causing safety hazards; 5) It is difficult to replace a single flame-blocking brick after it breaks. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a flame-blocking brick to enhance the flame-blocking effect of glass liquid at the overflow port; at the same time, a flame-blocking device for rolled glass overflow port using the flame-blocking brick is also provided to increase the area and distance of heat reflection of the fire-reducing brick body.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: a flame-blocking brick, which consists of an L-shaped brick body and a suspension part. The top surface of the L-shaped brick body extends upward to form the suspension part, and the suspension part is an inverted trapezoidal shape that is wide at the top and narrow at the bottom.

[0005] A rolled glass overflow flame-blocking device comprises a track, a moving beam, a hoist rope, a suspension beam, and a suspension rod, wherein the suspension beam is suspended under the moving beam through the hoist rope, and the moving beam is slidably mounted on the track, and also comprises a clamp and the flame-blocking bricks mentioned above;

[0006] A plurality of flame-blocking bricks are slidably assembled side by side in the same fixture, and the fixture is suspended under the suspension beam by a plurality of suspension rods.

[0007] Furthermore, the clamp has a clamping cavity that opens downward, and the clamping cavity is in the shape of an inverted trapezoid that is wide at the top and narrow at the bottom. The opening width at the bottom of the clamping cavity is smaller than the width at the top of the suspension part, and the flame-blocking brick is inserted into the clamping cavity from the left and right end ports of the clamping cavity through the suspension part.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the flame-blocking brick provided by the utility model patent can not only block the influence of the atmosphere in the kiln on the overflow port operation, but also serve as a heat-insulating brick. When used in combination with the heat-insulating brick, it can effectively reduce the heat loss of the overflow port. On the one hand, it has a good energy-saving and consumption-reducing effect, and on the other hand, it reduces the labor intensity of on-site operators. The flame-blocking device makes the overflow port flame blocking simple and efficient, and is convenient for changing machines and bricks and blowing, which greatly reduces the factors that cause roller damage to the calender unit due to defects caused by falling objects.

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0014] Reference Figure 2 It can be seen that a flame-blocking device for the overflow port of rolled glass includes a track 1, a moving beam 2, a hoist cable 3, a suspension beam 4, a suspension rod 5, a clamp 6, a flame-blocking brick 7 and other components.

[0015] The suspension beam 4 is suspended under the movable beam 2 by means of a hoist sling 3, and the movable beam 2 is slidably mounted on the track 1. The lifting and lowering of the flame-blocking brick 7 can be adjusted by means of the length of the hoist sling 3, and the inlet and outlet overflow ports can be realized by means of the movement of the movable beam 2 on the track 1. Moreover, the suspension rod 5 can be a telescopic structure, and the length of the suspension rod 5 can be adjusted according to the height of the flame-blocking brick 7 and the horizontality of the lower surface to achieve uniform force.

[0016] The above-mentioned suspension rod 5, suspension beam 4, hoist sling 3, movable beam 2, and track 1 are all prior art knowledge and are specific implementation means, which will not be repeated in this application. They can be implemented by referring to the patent CN105036522A solution or other prior art means in the field.

[0017] like Figure 1The flame-blocking brick 7 is composed of an L-shaped brick body 71 and a suspension portion 72. The top surface of the L-shaped brick body extends upward to form the suspension portion 72. The suspension portion 72 is in an inverted trapezoidal shape that is wide at the top and narrow at the bottom. The suspension portion 72 is integrally formed with the L-shaped brick body 71.

[0018] like Figure 3 The above-mentioned clamp 6 is made of heat-resistant steel clamp, and the clamp 6 has a clamping cavity 61 with an opening downward. The hanging portion 72 of the flame-blocking brick 7 can be slidably assembled in the clamping cavity 61 of the clamp 6 along the length direction of the clamp 6. The specific assembly method can be: the clamping cavity 61 is in an inverted trapezoidal shape that is wide at the top and narrow at the bottom, and the hanging portion 72 is in an inverted trapezoidal shape corresponding to the clamping cavity 61. The opening width at the bottom of the clamping cavity 61 is smaller than the width at the top of the hanging portion 72. The flame-blocking brick 7 is inserted into the clamping cavity 61 from the left and right end ports of the clamping cavity 61 of the clamp 6 with the hanging portion 72, so that the two can be slidably assembled, and the upper part of the insulation brick 7 can be in close contact with the clamp 6.

[0019] In this way, a plurality of flame-blocking bricks 7 can be assembled in parallel in the same fixture 6 , and then the fixture 6 can be suspended under the suspension beam 4 by a plurality of suspension rods 5 .

[0020] A plurality of flame-blocking bricks 7 are assembled in parallel in the same fixture 6 and freely combined to form a whole; in the working state, the flame-blocking bricks are tightly fitted to prevent the flame from directly penetrating through the brick seams; when a single flame-blocking brick is damaged, the broken brick can be directly removed and replaced with a new brick.

[0021] The flame-blocking brick 7 can not only block the influence of the atmosphere in the kiln on the overflow operation, but also serve as an insulation brick. When used in combination with the insulation brick, it can effectively reduce the heat loss of the overflow. On the one hand, it has a better energy-saving and consumption-reducing effect, and on the other hand, it reduces the labor intensity of on-site operators.

[0022] The flame blocking device makes the overflow port flame blocking simple and efficient, and is convenient for purging when changing machines and bricks, which greatly reduces the factors that cause roller damage to the calendering unit due to dropped object defects.
