Description

Heated air circulation type dryer
Technical field
The utility model relates to a kind of drying device, specifically the heated air circulation type dryer of a kind of vegetables.
Background technology
It is CN202873749U that State Intellectual Property Office discloses publication number on April 17th, 2013, patent name is a kind of utility model patent of dehydrated vegetables drying device, it includes pneumatic conveying drying high-voltaghe compartment, pneumatic conveying drying high-voltaghe compartment air inlet is provided with hot air flow device, pneumatic conveying drying high-voltaghe compartment top is provided with air diffuser, the material that moisture content is high is carried by hot-air and enters hydrofuge current divider along blast rising, until reduce blast when moisture content reaches setting value.This reciprocating drying means overcomes the moisture content problem of non-uniform that drying equipment in the past exists, and can work continuously.Air is conducted through drying box by the hot gas of crossing of high temperature and high speed, and in drying box, run hourly velocity all the time lower than air velocity, therefore heat and mass speed is very high, has dehydrating effect good, the feature of good stability.
There is following defect in technique scheme: steam enters air, both do not utilize waste heat, is not also fully used by steam, therefore do not meet the requirement of energy-conserving and environment-protective.
Summary of the invention
The purpose of this utility model is to provide a kind of heated air circulation type dryer utilizing steam waste heat combustion-supporting.
For achieving the above object, the technical scheme that the utility model adopts is:
Heated air circulation type dryer, it is sent into pipe, hot air reflux pipe, air exhauster, hot-air oven primarily of body of heater, heat exchanger, hot blast, take motor as the conveyer belt formation of power, the top of described body of heater is provided with chimney, described heat exchanger is located in chimney, the air intake that described hot blast sends into pipe is communicated with heat exchanger, the other end is communicated with the hot-wind inlet at the top of hot-air oven, the hot air reflux channel connection of described one end of hot air reflux pipe and the bottom of hot-air oven, and the other end is communicated with heat exchanger; Described conveyer belt is located in hot-air oven; The side lower part of described body of heater is connected with air blast, and the top of described hot-air oven is provided with vapour-discharge tube, and described vapour-discharge tube is connected with the air intake vent of air blast.
In described chimney and the top being positioned at heat exchanger is provided with secondary heat exchanger, described secondary heat exchanger is connected with cold water inlet pipe and hot water delivery pipe.
In described chimney and the top being positioned at secondary heat exchanger is provided with smoke filter.
Fuel in described body of heater is biological particles or coal or stalk.
The beneficial effects of the utility model: owing to adopting above-mentioned version, steam comb has been set up at the top of hot-air oven, steam in case can be drained, be conducive to the oven dry to vegetables, especially steam comb be connected with air blast, be not only conducive to and the dehumidifying in baking oven, and the waste heat of steam can also be made full use of, maximum beneficial effect is also, by after in steam suction body of heater, to be conducive to combustion-supporting, improves the calorific value in body of heater; Owing to having set up secondary heat exchanger, used heat has been only absorbed by the water, and used heat is fully used.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In figure: 1, body of heater; 2, heat exchanger; 3, hot blast sends into pipe; 4, hot air reflux pipe; 5, air exhauster; 6, hot-air oven; 7, conveyer belt; 8, chimney; 9, hot air reflux passage; 10, vapour-discharge tube; 11, secondary heat exchanger; 12, cold water inlet pipe; 13, hot water delivery pipe; 14, smoke filter; 15, air blast; 16, air intake vent.
Detailed description of the invention
As shown in Figure 1, heated air circulation type dryer, it is sent into pipe 3, hot air reflux pipe 4, air exhauster 5, hot-air oven 6 primarily of body of heater 1, heat exchanger 2, hot blast, is that the conveyer belt 7 of power is formed with motor, the top of body of heater 1 is provided with chimney 8, described heat exchanger 2 is located in chimney 8, the air intake that described hot blast sends into pipe 3 is communicated with heat exchanger 2, the other end is communicated with the hot-wind inlet at the top of hot-air oven 6, one end of described hot air reflux pipe 4 is communicated with the hot air reflux passage 9 of the bottom of hot-air oven 6, and the other end is communicated with heat exchanger 2; Described conveyer belt 7 is located in hot-air oven 6.The side lower part of body of heater 1 is connected with air blast 15, and the top of described hot-air oven 6 is provided with vapour-discharge tube 10, and described vapour-discharge tube 10 is connected with the air intake vent 16 of air blast 15.In chimney 8 and the top being positioned at heat exchanger 2 is provided with secondary heat exchanger 11, described secondary heat exchanger 11 is connected with cold water inlet pipe 12 and hot water delivery pipe 13.In chimney 8 and the top being positioned at secondary heat exchanger 11 is provided with smoke filter 14.
Fuel in described body of heater 1 is biological particles or coal or stalk.
The above is preferred embodiment of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
