Abstract
Description
Technical Field:
[0001] The invention relates to the technical field of aluminum liquid conveying troughs, and more specifically to an aluminum liquid conveying trough for temperature control based on natural gas catalytic combustion consumption. Background Art:
[0002] The existing continuous casting and rolling mill includes a melting furnace and a casting and rolling mill. The molten aluminum in the melting furnace is conveyed to the casting and rolling mill through a conveying trough for casting and rolling. The existing conveying trough is a trough-shaped steel structure channel, and a high-temperature heat insulation layer is provided on the outer side of the channel to reduce the heat loss of the molten aluminum in the conveying trough. However, during the flow of the molten aluminum in the conveying trough, heat is easily dissipated from its surface, resulting in the molten aluminum not reaching the casting and rolling temperature after being conveyed to the casting and rolling mill. Therefore, currently, a fire gun is generally used to spray flames onto the surface of the molten aluminum to achieve the effect of constant temperature by open fire heating. However, this heating and heat insulation measure has the following problems: 1. The firepower of the fire gun is directly related to the temperature change of the molten aluminum, but it is very difficult to set the firepower of the fire gun, and thus it is difficult to control the temperature of the molten aluminum; 2. The heat utilization rate of the fire gun is relatively low, and most of the heat generated by it is dissipated, and only a small part is transferred to the molten aluminum; 3. When the fire gun sprays flames, there is a situation of insufficient oxygen supply, which will cause incomplete combustion of the gas, resulting in a pungent smell of carbon monoxide in the workshop, affecting the physical health of employees and causing air pollution; Therefore, it is necessary to design a heating structure that can supply heat to the conveying trough and can achieve effective temperature control.

[0027] Thermal conductive mud 16 and glass fiber thermal insulation cotton 17 are respectively arranged on the inner and outer sides of the heating cavity. The thermal conductive mud 16 is fixedly pasted on the lower bottom surface and the two outer side walls of the inner channel 11; a plurality of transverse heat conduction tubes 13 are inserted between the thermal conductive mud 16 and the glass fiber thermal insulation cotton 17.

A connecting insertion tube 14 is inserted and fixed at the right end of the heat conduction tube 13, and a combustion catalyst coating 15 is coated and fixed on the inner wall of the heat conduction tube 13;

A vertical air inlet pipe 41 is arranged below the left auxiliary material tank 2. A number of shunt pipes are formed at the upper end of the air inlet pipe 41. The shunt pipes pass through the left protective channel plate 22 to form left bent pipes 411. The left bent pipes 411 are inserted and fixed at the left end of the air inlet connecting pipe 42. The right end of the air inlet connecting pipe 42 is inserted and fixed in the heat conduction pipe 13.
[0029] The right auxiliary material tank 3 includes a right channel 31 with a “U”-shaped longitudinal section. Right connecting plates 311 are formed at both ends of the right channel 31.

Because the distance between the melting furnace and the casting and rolling mill is relatively long, it is required that the main heating material tank 1 is relatively long. If a whole-structured material tank is used, the cost is high. By adopting a segmented structure, the cost can be effectively reduced.
[0031] A number of intermediate mounting holes are formed by the front and rear sides of the end plate 111 extending out of the outer housing 12.

[0033] The temperature control pipe 7 is composed of several rectangular pipes. Adjacent pipes are abutted against each other. Since the length of the main heating trough 1 is long, the length of the temperature control pipe 7 is also long. Using split-structured pipes to construct the temperature control pipe 7 is convenient for installation and can save costs at the same time.
[0034] Horizontal folding plates 121 are respectively bent and formed on the front and rear sides of the outer housing 12. The folding plates 121 respectively abut against the outer edges of the end plates 111. Self-tapping screws 20 are inserted into the support feet 9.

Using the self-tapping screws 20 can realize the installation and connection between the outer housing 12 and the inner channel 11 on the main heating trough 1, and at the same time complete the installation and connection of the temperature control pipe 7.
[0035] The igniter mounting bracket 6 includes a circular inner threaded barrel sleeve 61. A number of radial plates 62 are formed on the outer wall of the inner threaded barrel sleeve 61. The outer ends of the radial plates 62 are welded and fixed to the inner wall of the intake connection pipe 42. The electronic igniter 5 is screwed into the inner threaded barrel sleeve 61. This structure is convenient for the installation and disassembly of the electronic igniter 5 and is beneficial to the maintenance and replacement of the electronic igniter 5.

The sealing plate 30 is in a "human" shape and is respectively inserted and fixed in the diversion cut groove 73 of the temperature control pipe 7. The "human"-shaped sealing plate 30 can enable the air flow in the bypass pipe 34 to smoothly flow into the temperature control pipe 7 and realize the leftward flow of the air flow in the temperature control pipe 7.
[0038] An exhaust port communicating with the exhaust pipe 8 is formed on the upper end surface at the left end of the temperature control pipe 7. The exhaust pipe 8 is fixedly connected to the upper end surface of the temperature control pipe 7. A cover plate 81 extending downward is formed on the left side of the exhaust pipe 8. The cover plate 81 seals the pipe orifice at the left end of the temperature control pipe 7, and thus the final gas is discharged upward.
[0039] Working principle: This structure is a conveying trough for conveying aluminum liquid. Its main technical point is to use the heat generated by the catalytic combustion of natural gas for heating and heat preservation instead of directly spraying open flames on the surface of the aluminum liquid. The air inlet pipe 41 inputs a mixture of natural gas and air, which is first ignited by the electronic igniter 5 to realize the combustion of natural gas. After reaching the temperature of the catalytic combustion reaction, the electronic igniter 5 is turned off, and the heat generated by the catalytic combustion of the natural gas contacting the combustion catalyst coating 15 is used to heat the aluminum liquid in the inner channel 11 and compensate for the temperature lost by the aluminum liquid.
[0040] At the same time, the airflow after catalytic combustion carries heat from both ends into the temperature control pipe 7, forming a heat barrier above the inner channel 11 to limit the heat loss on the surface of the aluminum liquid, thereby playing a temperature control role.

Any person skilled in the art may modify the embodiments without violating the spirit and scope of the invention, and therefore the scope of protection of the invention shall be as set forth in the claims of the invention.
