Abstract

The present invention relates to a tunnel kiln airtight device, which arranges air blocking channels at two sides of a trolley movable in the tunnel kiln. The air blocking channels are arranged with the heat insulation airtight materials. The heat insulation airtight materials in the left and right air blocking channels tightly contact two inner walls at two sides of the tunnel kiln to form the airtight device. As such, hot air in the tunnel kiln when firing workpiece and cold air outside the kiln may not leak outside or penetrate inside through the channels between the inner walls at two sides of the tunnel kiln and the trolley, and the trolleys, which are mutually front and rear connected and movable in the tunnel kiln, do not allow the hot air and cold air to leak outside or penetrate inside due to left and right shifting. Therefore, the present invention not only can improve firing efficiency and quality of the workpiece, but also have energy saving and economic benefit for saving fuel, especially the trolley structure can avoid damage due to high temperature, to achieve long service life.

Description

Tunnel kiln airtight device

The invention relates to a tunnel kiln airtight device, in particular to a simple installation, simple operation and convenient use, the temperature in the tunnel kiln can be easily controlled and the temperature uniformity effect can be improved, and the tunnel kiln can be improved. The efficiency of the firing and the quality of the work, as well as the energy saving and economy of saving fuel, and the tunnel kiln airtight device which can prevent the structure of the trolley from being damaged by high temperature and achieve the effect of prolonging the service life.

According to the arrangement of the tunnel kiln and the method of burning the work, as shown in the first figure, the tunnel kiln 10 which is composed of refractory bricks and arched bodies is mainly included, and the work to be burned is provided ( The trolleys 20 carried by the bricks A are collectively composed. The tunnel 101 is provided with a rail 101 for sliding the wheel 202 of the trolley 20, and a longitudinal sand groove 102 is respectively disposed at a lower end of the inner wall of the two sides, and the longitudinal sand groove 102 is provided with heat resistance and airtightness. The sand material B of the effect is further provided with a plurality of sand-filling holes 103 connected to the outside of the tunnel kiln 10 in the longitudinal direction of the longitudinal sand channel 102, and the outer ends of the sand-filling holes 103 are provided with a lid 104 closed. The trolley 20 is provided with a steel carrier 201 for the workpiece A (such as a brick) to be placed. Under the carrier 201, a wheel 202 is disposed on the rail 101, and a steel partition 203 is disposed on each side of the carrier 201. The lower end of the partition 203 is inserted into the sand material B of the longitudinal sand groove 102 of the tunnel kiln 10, and a thick heat insulating material (such as refractory brick) 204 is laid on the carrier 201.

As described above, when the trolley 20 is slid in the tunnel kiln 10, a wide passage C is reserved between the two sides of the tunnel kiln 10 and the inner wall of the tunnel kiln 10, and the stern trolley 20 has a smooth displacement.

That is, the trolleys 20 carrying the objects A to be burned are slid into the tunnel kiln 10 one by one in a front-to-back connection manner, and are heated by the high temperature of the tunnel kiln 10, and the burned objects A are fired one by one. The tunnel kiln 10 is delivered one by one with the trolley 20.

It is undeniable that the implementation of the above-mentioned tunnel kiln can indeed carry out the firing operation of the burned work placed on the trolley. However, the operator also finds that there are still some shortcomings of the following shortcomings, which are treatable and must be improved. :

1. Since the passage C is reserved between the trolley 20 and the inner wall of the tunnel kiln 10, the high-temperature hot gas in the furnace will directly heat the partition 203 and the carrier 201 of the trolley 20 along the passage C, and the long-term use will not only The deformation and damage of the partition 203 and the carrier 201 are directly caused, and the structure and strength of the trolley 20 are also damaged.

2. As mentioned in the above paragraph, the baffle 203 and the carrier 201 of the trolley 20 are susceptible to thermal deformation, which may easily cause leakage of hot air in the tunnel kiln 10 and infiltration of cold air outside the kiln. The heating efficiency of 10 is greatly reduced.

3. Please cooperate with the second and third figures. Since the trolley 20 carrying the burnt work A is extremely heavy, it will cause a great friction between the wheel 202 and the track 101 due to the great friction during long-term sliding on the track 101. The gap is getting bigger and bigger, and the slippage of the trolley 20 often occurs in the left and right free state, and the left and right free displacement phenomenon is very easy to cause the two sides of the trolleys 20, 20', 20" to be connected to each other. The upper end position of 203', 203" directly produces an open gap D, and this gap D directly causes the leakage of hot air in the tunnel kiln 10 and the infiltration of cold air outside the kiln, thereby affecting the tunnel kiln 10 Heating efficiency. That is, the partition 203 on both sides of the trolley 20 inserts the lower end into the longitudinal sand groove 102 of the tunnel kiln 10 and is closely adhered by the sand material B in the sand groove 102, but when the front and rear side vehicles 20 that are connected are separated from each other, The upper end of the front and rear partitions 203, which are originally closely connected, will inevitably open. The void D, and the cold and hot air are infiltrated and leaked.

4. As mentioned above, since the carrier 201 and the two side partitions 203 of the trolley 20 are easily deformed, the front and rear vehicles 20 that are connected to each other are prone to left and right free displacement, and the front and rear partitions 203 form an open gap D. Then, the hot gas in the tunnel kiln 10 will easily leak a large amount along the channel C, and the cold air can easily enter the tunnel kiln 10 by the gap D, which will not only affect the heating of the tunnel kiln 10. The efficiency also causes the temperature in the tunnel kiln 10 to be difficult to control, and the hot and cold phenomenon often occurs. For this reason, the burned work A often has a firing efficiency of undercooking or undercooking. And the quality is not good.

5. As mentioned above, due to the poor heating efficiency of the tunnel kiln 10, there will be more fuel consumption.

6. In order to reduce the leakage of hot air in the tunnel kiln 10, the sand filling hole 103 is to be provided with the cover body 104. However, the action of the loading and unloading body 104 is troublesome, inconvenient and inconvenient for the implementation of sand filling. Efficiency shortcomings.

The main object of the present invention is to provide a tunnel kiln airtight device which can improve the above-mentioned defects, and which has better heating efficiency for the tunnel kiln, and the workpiece to be fired has better firing efficiency and The quality, as well as the fuel economy, are energy-saving and economical, and can effectively prevent the structure of the trolley from being damaged by high temperature and achieve the effect of prolonging the service life.

In order to achieve the above object, the present invention provides a gas barrier on both sides of the trolley in the tunnel kiln, and a heat insulating and airtight material on the air blocking duct, and the heat insulating and airtight material of the left and right air blocking ducts and the tunnel The inner walls of both sides of the kiln are closely connected; accordingly, the hot air in the tunnel kiln of the fired work and the cold air outside the kiln will not be from the inner wall of both sides of the tunnel kiln and the trolley of The leakage or infiltration of the channel occurs, and the trolleys that are connected to each other and displaced in the tunnel kiln will not leak and infiltrate from the junction between the hot gas and the cold air due to the mutual left and right dissociation. It can improve the burning efficiency and quality of the work, and also save fuel and save energy and economy. In particular, the structure of the trolley can prevent damage by high temperature and achieve the effect of prolonging the service life.
