Abstract

The utility model relates to an environment-friendly drying device, which comprises a storage box and a suction fan, wherein the suction fan and the storage box are hermetically and fixedly connected through a pipeline; an inner box is arranged in the storage box; the peripheral outer wall of the inner box consists of two layers of stainless steel pore plates; an outer layer pore plate is movable; two interlayers are formed between the outer wall of the storage box and the inner box; a first interlayer from inside to outside is filled with two groups of drying agents; a humidity sensor and a temperature sensor are arranged between the drying agents; a honeycomb ceramic heating plate is placed on a second interlayer; a heating plate starting switch and a pore plate moving switch are connected with the two sensors, thereby constructing a central control circuit; the humidity sensor and the temperature sensor are used together for controlling the switch-on/off of the heating device; a pipeline connected with the suction fan is communicated with the first interlayer. By combining the drying agents with a humidity-sensitive sensor, continuous drying of target articles is realized, a good drying effect is achieved, and environmental pollution is avoided.

Description

A kind of green drying device

Technical field

The utility model relates to a kind of drying device.

Background technology

On market, mainly contain two kinds of dehumidification modes now, one is that another kind is electronic cooling with moistureproof pearl moisture absorption.

The proof cabinet that utilizes the physics mode of moisture absorption pearl moisture absorption to manufacture, adopt drier, need 170 DEG C of heating that absorbed moisture is evaporated, add that applying shape memory alloy control is air-breathing, air bleeding valve, complete the action of dehumidifying hydrofuge, its characteristic is adopted for a long time in a large number because cost is lower, must notice that its temperature inside the box in the time of heating hydrofuge can raise, and has moisture regain in a big way.Adopt the proof cabinet of manufacturing in this way and the humidity in case can only be controlled to certain segment limit, because this mode is not taking the humidity in case as the duty according to deciding dehumidifying movement, but establish regular time program, open movement and close movement so that time is up, so humidity value is unstable.And this type of drying material regeneration rate is low, be unsuitable for repeatedly repeating efficient utilization.

Electronic cooling technology adopts semiconductor wafer low temperature dehumidification technology exactly, the Zhe Shi U.S. boat material that too science and technology is used, it is a kind of wafer refrigeration material, use direct current, power consumption is minimum, safety, stable, environmental protection, dehumidifying power are strong, three hours can be except the humidity value to 40%, importantly dehumidification process does not get damp again, even humidity is also slow rise after power-off, and can not produce fuel factor, this technology is by semiconductor condensing unit, the water vapor absorption in cabinet to be aggregated into liquid to discharge, and outside cabinet natural evaporation in air.The advantage of electronic dampproof box is exactly convenient, and shortcoming is exactly that price is slightly expensive.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of cost green drying device low, free from environmental pollution.

For solving the problems of the technologies described above, green drying device of the present utility model, comprise storage bin and air exhauster, air exhauster is fixedly connected with through seal for pipe joints with storage bin, is provided with interior case in storage bin, and interior case surrounding outer wall is made up of two-layer stainless steel orifice plate, outer orifice is removable, between storage tank outer wall and interior case, there are two interlayers, two groups of drier of first Sandwich filling moulding from inside to outside, drier intermediate arrangement humidity sensor and temperature sensor; Second interlayer placed honeycomb type ceramic heating plate, the heating plate starting switch organization center control circuit that is connected with two kinds of sensors with orifice plate moving switch, controlled the startup of heater by humidity sensor and close together with temperature sensor, the pipeline that connects air exhauster is communicated with first interlayer.

This device comprises two groups of recyclable regenerative drier that independently can be used alternatingly and two heaters by moisture sensor and temp-sensitive sensor control altogether.Cardinal principle is to utilize humistor to monitor the water absorption of drier, in the time reaching maximum water absorption, opens the isolation heater to drier, makes its dehydration regeneration, makes another group drier start working simultaneously.In the time that the humidity and temperature of heated drier reaches respectively requiring of can recycling, close heater, wait for and being utilized next time.The steam that heating is deviate from detaches device by the air exhauster that is placed in top through pipeline.So move in circles, realize the uninterrupted of target item is dried.

Drier is combined with moisture sensor, realize the uninterrupted of target item is dried, water absorption is about 2 times of unmodified silica gel analog value, and moisture absorption speed improves more than 3.5 times.The regeneration temperature of composite drying agent is low 10 DEG C before than modification, and Desorption Activation Energy of Carbon numerical value is little, and substantially no longer changes.Drier is corrosion-free, nontoxic, nuisanceless, after discarding, does not pollute the environment, can natural degradation.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is the structural representation of green drying device of the present utility model.

Detailed description of the invention

As shown in Figure 1, green drying device of the present utility model, comprise storage bin 1 and air exhauster 2, air exhauster 2 is sealedly and fixedly connected through pipeline 3 with storage bin 1, is provided with interior case 4 in storage bin 1, and interior case 4 surrounding outer walls are made up of two-layer stainless steel orifice plate, outer orifice is removable, between storage tank 1 outer wall and interior case 4, there are two interlayers, two groups of drier of first interlayer 5 filling moldings from inside to outside, drier intermediate arrangement humidity sensor 6 and temperature sensor 7; Second interlayer 8 placed honeycomb type ceramic heating plate 9, the heating plate 9 starting switches organization center control circuit that is connected with two kinds of sensors with orifice plate moving switch, controlled the startup of heating plate 9 by humidity sensor 6 and close together with temperature sensor 7, the pipeline 3 that connects air exhauster 2 is communicated with first interlayer 5.
