Description

A dry hot air box

technical field

The utility model relates to production equipment for zipper materials, in particular to a drying hot air box.

Background technique

In the monofilament production process of the zipper, PET particles need to be dried. At present, the commonly used drying process is carried out in a hot air box. The function of the hot air box is to heat the air flow and send out hot air. The existing hot air box uses Most of the heating components are heated by heating tubes. Due to the high power and high power consumption, the heating speed is relatively slow, and the heating is uneven, and the temperature change is not easy to control accurately. The uneven heating of the heated product will cause serious hidden dangers to the stability of the product quality, and also waste a large amount of power resources at the same time.

Utility model content

The utility model provides a dry hot air box, which is evenly heated, has high heating efficiency, saves energy, and has a simple structure.

The utility model specifically adopts the following technical solutions to realize:

A drying hot air box, including a box, a box body used for drying operations, a material inlet and a material outlet are provided on the box; a conveying device is erected inside the box to carry items to be dried, One end of the conveying device corresponds to the material inlet, and the other end corresponds to the material outlet; the hot air drying module adopts a modular design and is installed on one side of the case correspondingly, and the said machine is assembled according to the length of the case. The number of hot air drying modules.

Preferably, the hot air drying module is provided with an air outlet and an air suction port, the air outlet corresponds to a lower position of the conveying device, and the air suction port corresponds to an upper position of the conveying device.

Preferably, the hot air drying module is provided with an evaporator, a condenser, a compressor and a throttle valve, the evaporator corresponds to the air suction port, and the condenser corresponds to the air outlet.

Preferably, a fan is provided on the other side of the condenser.

The beneficial effect of the drying hot air box provided by the utility model is that the hot air drying module adopting the heat pump principle has low power consumption and energy saving, and the generated hot air effectively ensures that the heat is evenly transmitted, effectively ensuring the drying and heating effect of the air box.

Detailed ways

In order to further illustrate various embodiments, the utility model provides accompanying drawings. These drawings are part of the disclosure content of the present invention, which are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementations and advantages of the present utility model. Components in the figures are not drawn to scale, and similar component symbols are generally used to denote similar components.

The utility model is further described now in conjunction with accompanying drawing and specific embodiment.

As shown in Figure 1-5, a kind of dry hot air box that present embodiment provides, comprises cabinet 1, is used for the casing of drying operation, is provided with feed inlet 11 and discharge outlet 12 on cabinet 1; 2. It is erected inside the chassis 1 to carry the items to be dried. One end of the conveying device 2 corresponds to the material inlet 11, and the other end corresponds to the material outlet 12; at least two sets of hot air drying modules 3 adopt a modular design and are installed on the corresponding On one side of the chassis 1, the number of hot air drying modules 3 is assembled according to the length of the chassis 1. The hot air drying module 3 adopts heat pump technology, and is provided with an air outlet 31 and an air suction port 32. The air outlet 31 of the hot air corresponds to the lower position of the conveying device 2, and the air suction port 32 corresponds to the upper position of the conveying device 2. The inside of the hot air drying module 3 There is an evaporator 33, a condenser 34, a compressor (not shown) and a throttle valve (not shown), the evaporator 33 corresponds to the air inlet 32, the condenser 34 corresponds to the air outlet 31, and the other side of the condenser 34 Fan 35 is provided to increase forced convection.

When the hot air box of the present application is in use, evaluate the length and the size of the conveying device 2 to be assembled according to the quantity of articles to be dried. When the conveying device 2 and the cabinet 1 are assembled, one end of the conveying device 2 corresponds to the inlet of the cabinet, and the other One end corresponds to the discharge port of the chassis, and the items fall into the conveying device 2 from the feed port, and are sent out through the discharge port 12 through the transportation of the conveying device 2 . The hot air drying module 3 is correspondingly installed on one side of the chassis 1. The items to be dried are conveyed slowly on the conveying device 2, and then start each group of hot air drying modules 3, and the hot air is output from the air outlet 31 below the conveying device 2, and the hot air goes up to take away the moisture of the articles on the conveying device 2, Then it is inhaled through the air suction port 32 to complete the drying operation and sent out through the discharge port 12.

Although the utility model has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that, without departing from the spirit and scope of the utility model defined by the appended claims, changes in form and details may be made. Making various changes to the utility model is within the protection scope of the utility model.
