nitrile disposable glove making machine

 【Background technique】

Nitrile gloves are currently widely used in electronics factories, medical inspections, food industry, housework, chemical industry and other industries. They have good physical properties and outstanding chemical properties, which provide huge prices for production and life, and are unanimous by all industries. Praise.

In the production of nitrile gloves, the dipping material of the hand mold on the production line needs to go through multiple stages such as cleaning, coagulant, glue, filtering, cooling, and chlorine washing. These stages are often accompanied by heat loss, which gives us the actual production. Bringing serious losses; on the one hand, some overflow tanks, such as pickling tanks, alkali washing tanks, and water washing tanks have a higher temperature, which can reach 70-90°C, and the temperature of the filtering tank is 40-50°C, and the cooling tank The temperature is 50-60°C, the heat in these tanks will generally be dissipated into the air or taken away by the overflowing tank liquid, causing great waste. On the other hand, the temperature of receiving tanks such as glue tanks and coagulant tanks is average. It needs to be controlled at 30°C _40°C. In winter, it needs heating and heat preservation, which consumes a lot of resources, which greatly increases production costs. Therefore, designing a reasonable waste heat utilization system and using the heat lost in the overflow tank to the receiving tank has become a problem to be solved urgently.

 Utility model content

In order to solve the deficiencies in the above technical problems, the purpose of the present invention is to provide a waste heat utilization system for a nitrile glove production line, which can effectively utilize the heat generated by the overflow tank to the receiving tank, reduce heat loss, and achieve savings The role of energy and cost saving.

The technical solutions adopted by the utility model to solve its technical problems are:

The waste heat utilization system of the nitrile glove production line includes an overflow tank, a recovery tank, a receiving tank, a cold water tank and a heat pipe heat exchanger. The overflow tank is connected to the liquid inlet of the diverter valve through an overflow pipe, and one of the diverter valves is The liquid outlet is connected to the liquid inlet of the high temperature end of the heat pipe heat exchanger through a shunt pipe, and the other liquid outlet is connected to the liquid inlet of the recovery tank through a shunt pipe. The shunt pipes are equipped with water pumps and heat pipe exchanges. The liquid outlet of the high temperature end of the heat exchanger is connected with the liquid inlet of the recovery tank through a connecting pipe, and the liquid outlet of the recovery tank is connected with the liquid inlet of the overflow tank through an output pipe; the liquid outlet of the receiving tank is connected through an output pipe Connected with the liquid inlet of the low temperature end of the heat pipe heat exchanger, the liquid inlet of the receiving tank is connected with the liquid outlet of the low temperature end of the heat pipe heat exchanger through the return pipe, and the liquid outlet of the cold water tank exchanges heat with the heat pipe through the output pipe The cold end of the heat exchanger is connected with the liquid inlet, the liquid inlet of the cold water tank is connected with the cold end liquid outlet of the heat pipe heat exchanger through a return pipe, and a water pump is provided on the output pipe.

When the temperature of the tank liquid in the receiving tank needs to be increased, open the three-way valve, introduce the high-temperature overflow liquid in the overflow tank into the heat pipe heat exchanger, and heat the tank liquid in the receiving tank through the heat pipe heat exchanger. The low-temperature overflow liquid of the heat exchanger can flow into the recovery tank for recycling, and finally the recovered liquid flows back to the overflow tank. When the tank liquid in the receiving tank does not need to be heated, the overflow liquid can directly flow into the recovery tank for recovery Utilization; When the temperature of the tank liquid in 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 tank liquid in the receiving tank, and the recovered water after cooling flows directly back into the cold water tank.


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

The utility model can recover the waste heat of the overflow tank on the nitrile glove production line, and heat the receiving tank through the heat pipe heat exchanger, which not only saves the cost, but also ensures the recycling of heat, which is beneficial to sustainable development; The system can realize heating and cooling functions at the same time, making temperature control more accurate, which is very beneficial to production.
