The trolley is a device used for industrial furnaces such as tunnel furnaces, mainly has the functions of bearing raw materials (steel coils) to move in the furnaces, sealing the furnace bodies and the like, and is a main component of the industrial furnaces such as the tunnel furnaces. In the trolley in the related art, when the trolley enters and exits the furnace, more heat is taken away, the energy consumption of the furnace is increased, and a large amount of energy is wasted. In view of the above situation, the applicant provides a trolley and kiln production system on the basis of a great amount of theoretical research and actual operation. The support structure of this platform truck has seted up and has subtracted matter hole, has reduced the quality of plummer, has reduced the energy consumption of kiln. The heat of the kiln taken away when the trolley of the kiln production system enters and exits the kiln is less, and the energy loss of the kiln production system is less.

Examples

In the trolley in the related art, when the trolley enters and exits the furnace, more heat is taken away, the energy consumption of the furnace is increased, and a large amount of energy is wasted. The applicant has found, on the basis of a great deal of theoretical research and practical operation, that the reasons for the above problems are: the refractory material of the related art trolley is too high in mass. The trolley is in a cold state when entering the furnace along with the piece to be fired, is heated along with the piece to be fired in the heating process of the piece to be fired, and is pushed out from the tail of the furnace after reaching a certain temperature. According to the conservation of energy, the larger the mass of the refractory material of the trolley is, the more heat is absorbed, thereby causing larger energy waste and increasing the energy consumption of the kiln.

Referring to fig. 1 and fig. 2, the present embodiment provides a trolley 10, the trolley 10 includes a body 200 and a carrying platform 100, the body 200 is connected to the carrying platform 100, and the body 200 supports the carrying platform 100 and drives the carrying platform 100 to move.

The support structure 110 is fixed by the fixing layer structure 120, and the sealing layer 130 is disposed around the fixing layer structure 120. The lower portion of the support structure 110 is formed with a mass reduction hole 111, and the upper portion of the support structure 110 is used for placing raw materials. By arranging the supporting structure 110 and the fixing layer structure 120 and fixing the supporting structure 110 by the fixing layer structure 120, the carrier 100 has better stability and does not shake or tilt. By arranging the sealing layer 130, the sealing effect on the furnace body is achieved, and the energy consumption of the furnace is reduced. The mass reducing holes 111 are formed in the support structure 110 to reduce the mass of the refractory material of the trolley 10. According to the law of conservation of energy, the mass of the refractory material of the trolley 10 is reduced, and the absorbed heat is also reduced, so that the heat brought out by the trolley 10 when the trolley enters and exits the furnace is reduced, the energy consumption of the furnace is reduced, and the energy is saved.

In the present embodiment, in order to reduce the mass of the trolley 10 as much as possible, the first layer 121 and the second layer 122 are cast by using a lightweight cordierite-mullite castable to fix the support structure 110, and simultaneously, the support structure has a sealing effect on the trolley body 200, so that the heat conduction from the kiln to the trolley body 200 is reduced. It should be noted that the insulation material should be selected to be lighter in weight to minimize the mass of the trolley 10. In this embodiment, the heat preservation material selects the heat preservation cotton, and the cotton weight of heat preservation is lighter to the thermal conductivity is less, and thermal-insulated effectual.

In the present embodiment, referring to fig. 2, the supporting structure 110 is an arch structure. Providing the support structure 110 as an arch results in less mass while providing better support capability for the support structure 110.
