Description

Drying chamber

Technical field

The utility model relates to the material dehumidification equipment fields such as PET, PC, relates in particular to the energy saver of dehumidification equipment.

Background technology

In order to guarantee the quality of production and processing goods out, dehumidification equipment is in the plastic processing industry auxiliary equipment that is absolutely necessary.

The drying chamber 100 of traditional structure is normally by interior tank body 110(SUS304), heat-preservation cotton 130, outer tank body 120(Q235 or other materials), intake stack 140 and wind pipe 150 (as shown in Figure 1) that form.So be exactly that material directly contacts with the interior tank body 110 of drying chamber, heat transmits by stainless steel generation heat.But dehumidification equipment is that the energy consumption of continuous operation is all larger, in order to reduce the loss of heat, usually adopts the thickening heat-preservation cotton in the prior art, but has directly so just caused the increase of drying chamber wall thickness to seem too heavy.

Therefore, in order to reduce energy consumption to reduce production costs, certainly will require dehumidification equipment to carry out some technological innovations.

As everyone knows, the propagation of heating power has three kinds of approach: heat radiation, thermal convection current and heat conduction.For dry materials, be to take away the moisture on material surface to reach the effect of removal moisture drying material by the convection current of hot-air; The loss of drying chamber surface heat then occurs by heat radiation and two approach of heat conduction.

Heat radiation refers to object owing to having temperature and the phenomenon of radiated electromagnetic wave.The object that all temperature are higher than absolute zero can both produce heat radiation, and the higher gross energy that gives off of temperature is just larger.

To be heat pass to another part or passed to the phenomenon of another system by a system from the part of system for heat conduction, and the temperature difference between object or intrasystem each point is heat conducting necessary condition.

Because dry run is to finish circulation in an airtight space, heat transfer be by dry air and material contact occur.Clearly, heat radiation is inevitable.

This shows, can only seek from heat conduction aspect a kind of energy saver that can reduce thermal loss.

The utility model content

In order to overcome above defective, the purpose of this utility model is to provide a kind of drying chamber with energy saver.

To achieve these goals, the utility model provides a kind of drying chamber, it comprises: intake stack, wind pipe, interior tank body, outer tank body and be arranged on described interior tank body and described outer tank body between the heat-preservation cotton layer, wherein, in described interior tank body, has a supplies room, between described supplies room and described interior tank body, be provided with air buffer, be connected by described air buffer between described supplies room and the described wind pipe.

Preferably, in the utility model, described supplies room is connected with described air buffer at described interior tank body top.

Preferably, in the utility model, described wind pipe is arranged on the side of described drying chamber.

Preferably, in the utility model, described wind pipe is connected with dehumidifying device outside described drying chamber.

Preferably, in the utility model, described intake stack is connected with cartridge heater outside described drier, described intake stack extends through described outer tank body, described heat-preservation cotton layer, described interior tank body and described air buffer to described supplies room from described cartridge heater, and forms a mouth of pipe downwards.

Preferably, in the utility model, the described mouth of pipe is the wide-mouth shape.

Preferably, in the utility model, described mouth of pipe place is provided with filter screen.

Based on above-mentioned setting, in drying chamber provided by the utility model, increase air buffer in order to reduce the loss of heat on the basis that does not increase the heat-preservation cotton layer thickness, to adopt one in interior tank interior, be similar to the principle of vacuum cup insulation, adopt air buffer to come tank body is incubated.

The specific embodiment

Below, further set forth the advantage of the utility model in connection with specific embodiment and accompanying drawing.

Referring to Fig. 2, the drying chamber 200 that provides for the utility model one preferred embodiment, it comprises: intake stack 240, wind pipe 250, interior tank body 210, outer tank body 220 and be arranged on heat-preservation cotton layer 230 between interior tank body 210 and the outer tank body 220, wherein, in interior tank body 210, has a supplies room 260, be provided with air buffer 270 between supplies room 260 and interior tank body 210, air buffer 270 is being communicated with supplies room 260 and wind pipe 250.

In the preferred embodiment, intake stack 240 is connected with cartridge heater 280 outside drying chamber 200, and extend through outer tank body 220, heat-preservation cotton layer 230, interior tank body 210 and air buffer 270 to supplies room 260 from cartridge heater 280, and in supplies room, form a mouth of pipe 241 downwards.Supplies room 260 is on its top, and namely the top of interior tank body 210 is connected with air buffer 270.

So, the dry gas from cartridge heater 280 can enter in the supplies room 260 along intake stack 240.After the abundant drying with material, gas will enter by the top of supplies room 260 air buffer 270, although enter the temperature of gas of air buffer 270 less than the gas temperature in the supplies room 260, but it still has certain heat, and the existence of air buffer 270, avoided material directly to contact with the direct of interior stainless steel tank wall, simultaneously, because the thermal conductivity factor (0.023W/mk) of air is much smaller than stainless thermal conductivity factor (20～30W/mk).Therefore, can effectively reduce to a great extent the thermal loss that produces because of the heat conduction.

In the preferred embodiment, the mouth of pipe 241 can be a wide-mouth shape, and is equipped with filter screen 242, enters in the pipeline to avoid material.

In the preferred embodiment, wind pipe 250 is arranged on the side of drying chamber 200, rather than 200 tops of drying chamber as shown in Figure 1, so more is convenient to install.

Should be noted that, embodiment of the present utility model has better implementation, and be not that the utility model is done any type of restriction, any person skilled in art of being familiar with may utilize the technology contents change of above-mentioned announcement or be modified to the effective embodiment that is equal to, in every case the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any modification or equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
