[patent description] waste heat utilization system for nitrile glove production line

[technical field]

The utility model relates to waste heat recovery and utilization, in particular to a waste heat utilization system of nitrile glove production line.

Background technology

Nitrile gloves are now widely used in the electronics factory, medical inspection, food industry, housework, chemical industry and other industries, it has good physical performance and outstanding chemical performance, for production and life to provide a huge cheap, by the industry praise.

During the production of nitrile gloves, the dip material of the hand mold on the production line needs to go through several stages, such as cleaning, coagulation agent, glue sticking, filtration, cooling, chlorine washing, etc. These stages are often accompanied by the loss of heat, which brings serious losses to our actual production.On the one hand, the overflow groove, such as pickling tank, dissolving tank, water tank temperature is higher, up to 70-90 ° C, wash tank filter is 40 to 50 ° C temperature, cooling temperature of 50-60 ° C, the slot will typically heat into the air or taken away by the overflow groove liquid, caused great waste, on the other hand, the glue tank, solidifier tank such as receiving tank temperature generally need to control in 30 ° C _40 ° C, in the winter to heat insulation, consume a large amount of resources, this is largely increased the cost of production.Therefore, it is an urgent problem to design a reasonable waste heat utilization system and utilize the heat lost in the overflow tank to the receiving tank.

Contents of utility model

In order to solve the shortcomings of the above technical problems, the utility model aims to provide a waste heat utilization system of nitrile glove production line, which can effectively utilize the heat generated by the overflow groove into the receiving groove, reduce the heat loss, and save energy and cost.

The technical scheme adopted by the utility model to solve the technical problems is as follows:

Nitrile gloves production line of waste heat utilization system, including the overflow trough, recycling tank, receiving tank, cold water tank and heat pipe heat exchanger, the overflow groove through the overflow pipe and connected to the liquid into the mouth of the diverter valve, shunt valve of a liquid through the bypass pipe mouth and connected to the high temperature side into the inlet of the heat pipe heat exchanger, a fluid outlet through the bypass pipe and connected to the liquid into the mouth of the recycling tank, shunt pipe are described with the water pump, high temperature of heat pipe heat exchanger in the fluid outlet through the connecting pipe and connected to the liquid into the mouth of the recycling tank, recycling tank of liquid outlet through the output pipe and connected to the liquid into the mouth of the overflow groove;Receiving tank liquid outlet through the low end of the output pipe and heat pipe heat exchanger inlet fluid inlet connected to receiving tank liquid into the mouth through the return line and connected to the low temperature liquid outlet end of the heat pipe heat exchanger, cold water tank of liquid outlet through the output pipe and connected to the cold end into the inlet of the heat pipe heat exchanger, cold water tank of liquid into the mouth through the return line and connected to the cold end liquid outlet of the heat pipe heat exchanger, described with the pump output pipe.

When receiving groove groove liquid need higher temperature, open the 3-way valve, introducing high temperature liquid overflow of overflow groove heat pipe heat exchanger, heat through heat pipe heat exchanger for receiving groove liquid, flows through the heat exchanger in the low-temperature overflow fluid can flow into the recycling tank recycle, recycle, eventually recycle flow back to the overflow groove, when receiving groove groove liquid don't need to be heated, overflow liquid can be recycled directly into recycling tank;When the temperature of the receiving tank needs to be lowered, the cold water in the cold water tank can be introduced into the heat pipe heat exchanger to cool the liquid in the receiving tank, and the recovered water after cooling will flow directly back into the cold water tank.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model can recycle the waste heat of the overflow groove on the nitrile glove production line and heat the receiving groove through the heat pipe heat exchanger.This system can realize heating and cooling functions at the same time, making the temperature control more accurate, which is very beneficial to production.
