Abstract

The utility model relates to energy-saving industrial clothes drying apparatus, comprising a machine body with an air inlet passage and an exhaust passage, and a rotation drum which is arranged between the air inlet passage and the exhaust passage inside the machine body and is provided with through-holes. A heater is arranged in the air inlet passage, and an exhaust fan is positioned in the exhaust passage. The utility model is characterized in that: a hot air returning channel which is communicated with the air inlet passage at one side of the inlet port of the heater is arranged at the exhaust passage at one side of the exhaust fan port. The product of the utility model can heat the partial surplus hot air and then deliver the hot air to the rotation drum with through-holes for drying clothes used; thus, the drying efficiency is increased and the heat energy is saved.

Description

The energy-saving industrial cloth drying machine

The utility model relates to a kind of industrial cloth drying machine.

Existing industrial cloth drying machine (no matter being domestic production or external import), its structure generally includes heat exchanger 1 as shown in Figure 1, band mesh cylinder 2 and centrifugal blower 3.Its course of work is: clothing 4 that will be to be dried is put into band mesh cylinder 2, starting the dryer transmission mechanism rotates band mesh cylinder, centrifugal blower makes heat exchanger 1 inboard and band mesh cylinder 2 all produce negative pressure simultaneously, under the effect of air pressure, normal temperature air a becomes hot blast b after the heat absorption of both sides, top heat exchanger, clothing 4 is carried out heating, drying; The hot blast c that has a moisture after the centrifugal blower suction directly outside pipeline discharge machine.The major defect of this cloth drying machine is that hot blast c is utilized directly and is discharged, thereby very wastes heat energy.

The purpose of this utility model is a kind of energy-saving industrial cloth drying machine of design, is sent to the rotating cylinder with passage after it can utilize part of waste heat wind to heat again clothing is carried out heating, drying, thereby improve drying efficiency, saves heat energy.

The utility model is to constitute like this, it comprises the body with entering and exhaust channel and is located in the body and the rotating cylinder with passage between entering and exhaust channel, air intake duct is provided with air heater, exhaust duct is provided with exhaust blower, it is characterized in that: the exhaust duct of exhaust blower outlet one side is provided with the widely different stream by-path of hot blast that is connected with the air intake duct of air heater import one side.

The utility model is owing to can heat part or most of waste heat wind c once more in company with normal temperature air a by air heater, through repeatedly circulation heating, the temperature of hot blast b is more and more high with making, thereby can reduce drying time, improve drying efficiency, thereby realize saving the purpose of heat energy.Accelerated the clothing drying efficiency, a large amount of saving heat energy, in addition, the utility model also designs the device that cools off fast behind the clothing, cold wind import of this device design, and simultaneously the whole sealings of heat exchanger are not exchanged, cold wind directly enters the cylinder cooling clothing of band mesh after centrifugal blower is discharged, and makes clothing cool off taking-up fast.Because above-mentioned design, true with novel characteristics: 1, a large amount of heat energy 2, reduced the drying time of clothing greatly, the clothing that has improved after operating efficiency 3, the oven dry reaches quick desirable cooling effect.

Below in conjunction with drawings and Examples the utility model is specifically described.

Fig. 1 is existing industrial cloth drying machine organigram.

Fig. 2 is the utility model drying work view.

Fig. 3 is the utility model cooling clothing working state schematic representation.

With reference to Fig. 2 and Fig. 3, the utility model comprises the body with entering and exhaust channel 5.6 and is located in the body and the rotating cylinder with passage 7 between entering and exhaust channel, air intake duct is provided with air heater 8, exhaust duct is provided with exhaust blower 9, it is characterized in that: the exhaust duct of exhaust blower outlet one side is provided with the widely different stream by-path 10 of hot blast that is connected with the air intake duct of air heater import one side.The widely different stream by-path of hot blast is provided with air door 11.

In order to help the oven dry of clothing, the rotating cylinder inwall is provided with the wing plate 16 in order to lift clothing.

In order to help the quick cooling after clothing is dried, body is provided with bypass cold wind access 12, but bypass cold wind access is provided with the valve 13 of opening and closing of fault air intake duct and sealing simultaneously or unlatching bypass cold wind access.The import of the import of air intake duct and bypass cold wind access is adjacent and be positioned at same horizontal plane, valve by two fans through side be connected into one and mutually at an angle of 90 plate washer constitute, the middle part dumpling of valve is connected in the middle of the import of the import of air intake duct and bypass cold wind access, so that it can block the import 14 of air intake duct or the import 15 of bypass cold wind access respectively when just changeing or reversing.

The course of work of the utility model embodiment is as follows: waste heat hot blast c is through the exhaust blower pump drainage, because of being subjected to the influence of air door 11 openings of sizes, generally can only discharge the waste heat wind c that has moisture on a small quantity, discharge how many waste heat wind c, just can replenish how many normal temperature air a through air intake duct, when normal temperature air a and waste heat wind c are combined into wind a+c again after the air heater heating, forming hot blast b dries clothing, then, waste heat wind c is still a small amount of discharge, replenish normal temperature air a once more, normal temperature air a and waste heat wind c are combined into hot blast a+c again through the air heater heating, so repeatedly repeatedly, the hot blast heating that constantly circulates, the temperature of hot blast b also constantly raises, and is increased to uniform temperature and can regulates air heater, temperature is under the optimum state works.

After clothing is dried in dryer, close the air door on the widely different stream by-path of hot blast earlier, rotate counterclockwise valve again, seal air intake duct and open bypass cold wind access simultaneously, the cold wind a that cool off clothing this moment directly enters the rotating cylinder with passage through bypass cold wind access, after clothing cooled off, waste heat wind c directly discharged dryer through exhaust duct through the exhaust blower pump drainage.
