Embodiment Construction

[0008] Mesh belt quenching heat energy recovery system, including sequentially connected feeding machine 1, front cleaning machine 2, quenching furnace 3, quenching tank 4, cleaning machine 6, tempering furnace 7 and tempering tank 8, quenching tank 4 is equipped with a set The heat tank 5, the heat collecting tank 5, the front cleaning machine 2 and the cleaning machine 6 are connected by a water inlet pipe 10 and a return pipe 9, and a pump 11 is arranged on the return pipe 9.

[0009] After adding a heat exchange heat collecting tank 5 on the quenching tank 4, the temperature of the heat collecting tank 5 is basically consistent with the temperature of the quenching tank, and the cleaning liquid installed in the heat collecting tank 5 is directly sent to the cleaning machine. It is used for product cleaning to achieve a better cleaning effect, and the cleaning liquid returns to the heat collecting tank again. If each production line produces 320 days per year, 27kw*2 sets*3...

Abstract

The invention discloses a mesh belt quenching heat energy recovery system which comprises a feeder (1), a front cleaning machine (2), a quenching furnace (3), a quenching tank (4), a cleaning machine (6), a tempering furnace (7) and a tempering bath (8) sequentially connected, wherein a heat collecting tank (5) is arranged on the quenching tank (4); and the heat collecting tank (5) is connected with the front cleaning machine (2) and the cleaning machine (6) through a water inlet pipe (10) and a water return pipe (9), and a pump (11) is arranged on the water return pipe (9). The mesh belt quenching heat energy recovery system disclosed by the invention has the beneficial effects of reducing energy consumption, avoiding electric heating, and being good in cleaning effect, energy-conservation and low in carbon.

Description

technical field [0001] The invention relates to a heat energy recovery device in a heat treatment mesh belt furnace, in particular to a mesh belt type quenching heat energy recovery system. Background technique [0002] The temperature of the quenching tank is generally controlled at 70-80°C. As high-temperature workpieces continue to enter the quenching tank, the quenching tank will continue to heat up. The cooling must be completed through heat exchange between the plate heat exchanger and the external cooling water, otherwise the product quality and process will be affected. , or even the product is scrapped, so this heat exchange is necessary, and a lot of energy is wasted in this process. The cooling problem of the existing heat treatment mesh belt quenching oil tank is to directly exchange heat with the external cooling water, resulting in a large amount of heat energy. waste. In addition, it is better to require the oil stain cleaning degree on the surface of the wor...
