Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment, specifically to a waste heat utilization device for a roller furnace salt evaporator. Background Technology

[0002] In industrial fields such as ceramic firing, metal heat treatment, and semiconductor material processing, roller furnaces, as a type of continuous high-temperature heating equipment, have become one of the core production equipment due to their advantages of precise temperature control and stable material transmission. During operation, the internal temperature of the roller furnace is usually 800-1600℃. As a key isolation component between the furnace body and the outside world, the furnace door is subjected to harsh conditions of high-temperature radiation and alternating hot and cold temperatures for a long time. If effective cooling measures are not taken, problems such as furnace door deformation and aging and failure of seals are very likely to occur. Currently, when cooling the furnace door of roller bar heating furnaces, most methods focus solely on "cooling and protecting the equipment," neglecting secondary utilization. This results in the direct loss of a large amount of idle waste heat generated during the operation of the roller bar furnace, contradicting the current industrial development requirements of "energy conservation, emission reduction, and green production." The waste of a significant amount of idle heat energy makes it difficult to reduce production and operating costs (in the production processes of industries such as ceramics and metals, it is often necessary to heat the cleaning fluid used for cleaning workpieces, which requires the use of electric heaters, gas heaters, and other equipment). To address these issues, the inventors propose a waste heat utilization device for roller bar furnace salt evaporators. Utility Model Content

[0003] In order to address the problem that most cooling methods for roller furnace doors only focus on "cooling and protecting the equipment," resulting in the waste of a large amount of idle heat energy, the purpose of this invention is to provide a waste heat utilization device for roller furnace salt evaporators.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a waste heat utilization device for a roller furnace salt evaporator, comprising a furnace door frame and a cleaning tank, wherein a partition is provided at the outer end of the furnace door frame, and a cooling water pipe is provided on the partition; a water pump inlet pipe is fixedly connected to the side end of the cleaning tank near the bottom, a water pump body is fixedly connected to one end of the water pump inlet pipe, a water pump outlet pipe is fixedly connected to one end of the water pump body, and the other end of the water pump outlet pipe is fixedly connected to one end of a cold water pipe; a return water pipe is fixedly connected to the side end of the cleaning tank near the water pump inlet pipe, and the other end of the return water pipe is fixedly connected to the other end of the cold water pipe.

[0005] Preferably, a pressure detection switch is provided on the outer ring of the return water pipe, and a flow detection switch is provided on the outer ring of the return water pipe near the pressure detection switch.

[0006] Preferably, a valve is installed on the outer ring of the return water pipe near the cleaning tank.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a water pump body, a return water pipe, and a cooling water pipe to heat the cleaning liquid in the cleaning tank using the idle waste heat of the furnace door frame.

The pressure detection switch 7 is equipped with a digital display panel, which can display the pressure value inside the pipe in real time. The pressure detection switch 7 is also set with high and low pressure alarm thresholds. When the pressure exceeds the threshold, it can issue an audible and visual alarm signal.

A protective cover is installed on the outside of valve 9. The protective cover is made of transparent plastic material, which can effectively prevent dust and debris from entering the interior of valve 9.

[0019] Working principle: When in use, the water pump body 5 draws the cleaning fluid from the cleaning tank 3 and enters the cooling water pipe in contact with the furnace door frame 1 through the water pump outlet pipe 2 for cooling. Then, it is transported from the return water port of the cooling water pipe on the furnace door frame 1 to the return water pipe 6 and finally back to the cleaning tank 3. This allows the cleaning tank 3 to absorb the heat generated by the furnace door frame 1 during cooling, thus saving energy. In addition, a pressure detection switch 7 and a flow detection switch 8 are installed on the return water pipe 6 to ensure normal circulation of the circulating water.
