Description

Injection molding machine heat preservation and heat recovery purification device

                                                                  One, the technical field

The utility model belongs to an accessory of an injection molding machine, in particular to a heat preservation and heat recovery purification device for an injection molding machine.

                    II. Background technology

At present, quite a lot of plastic products in the industry are formed by injection molding machines. In the injection molding machine, after the plastic raw material enters the feeding chamber from the hopper, it is heated in the heat exchanger. The screw in the heat exchanger pushes the raw materials and stirs them evenly to avoid uneven heat in each part. Injection molding machines are generally heated externally, so heat loss is inevitable. In summer, the workshop is hotter; in winter, the heat dissipation is faster. Moreover, since the plastic powder is not dry, the injection molding machine generally has a drying barrel. During the drying process, dust escapes from the drying barrel and pollutes the environment, affecting the health of operators.

                                                                             

The task of the utility model is to provide a heat preservation and heat recovery purification device for an injection molding machine, which has energy saving and environmental protection benefits.

In order to accomplish the above tasks, the solution adopted by the utility model is: a heat preservation and heat recovery purification device for an injection molding machine, which has a heat preservation cover, and a heat extraction pipe connects the heat preservation cover to a fan cover, and the fan cover is fixed on the fan inlet. The air outlet, the upper opening of the fan cover is connected with a heat extraction pipe, the air outlet of the fan is connected with a heat transfer pipe, and the other end of the heat extraction pipe is connected with a purifier.

When in use, the purifier is connected to the upper opening of the drying barrel on the injection molding machine, the heat transfer pipe is connected to the lower opening of the drying barrel, and the heat preservation cover is covered outside the heater in the injection molding machine. Because the utility model has a heat preservation cover, the heater in the injection molding machine is kept warm and heat-collected, and the heat is sent from below to the drying material barrel of the injection molding machine through the heat pipe and the fan to heat and dry the raw materials in the barrel, and the hot air passes through the drying material After the barrel, there is still a certain amount of heat coming out of the top of the drying barrel. The powder contained in the hot air can be recycled after being purified by the purifier, and the hot air that comes out is recycled to the fan through the heat pumping pipe, which achieves energy saving and environmental protection. the goal of. In summer, the temperature of the workshop is reduced; in winter, the heat preservation effect of the injection molding machine heater is good. Reduce the dust content in the workshop and maintain the health of workers. When the plastic powder is replaced, it is much more convenient to clean the drying barrel due to the purifier.

                                                                                IV.
