Abstract
The utility model provides a hydropneumatic energy-saving grain drier, which belongs to the technical field of drying machinery. The grain drying and cooling of the utility model adopt a split design, and the water is taken as a heat conducting medium. Smoke exhaust pipelines and air preheating pipelines are arranged at intervals in a water filling furnace body. The grain drying adopts a mode that material heating plate contact baking and drying hole plate air drying are alternately carried out. The air with certain heat quantity which is discharged from the upper end of a cooling tower is again blown into the air preheating pipelines so as to be carried out with secondary utilization. Compared with the existing grain drier, the utility model has the advantages of high de-watering speed, favorable quality of dried grain, simple manufacturing process, and low cost. The heat utilization can be enhanced by 30 percent.
Description
The utility model relates to a kind of hydropneumatic energy-saving grain warm air drier, belongs to the oven dry field of mechanical technique.
At present, domestic most of foodstuff drying devices adopt boiler and warm air drier separate design, and heat conduction losses is big in the work, and manufacturing cost is high again, only use high-temperature gas to dry this a kind of dry dried mode when work, and drying efficiency is low.
The purpose of this utility model provides a kind of novel grain drying device, with water is heat-conducting medium, the drying chamber that combustion chamber and water-filling body of heater are surrounded connects as one, smoke discharging pipe and gas preheating pipe are spaced in the water-filling body of heater, the material heating plate is communicated with the water-filling body of heater, also be full of water, the oven dry orifice plate that has micropore is connected and is positioned at the oblique below of material heating plate with the material heating plate, grain heat-drying is to hocket through material heating plate contact toaster with by the gas drying that passes through the oven dry orifice plate that discharge gas preheating pipe lower end, accelerate the grain dewatering speed, improved the heat energy utilization rate.
The purpose of this utility model is achieved in that grain heat-drying and cooling employing split design, make that grain heat-drying part manufacturing process is simple, easy to maintenance, the stove fire of fired coal combustion and coal smoke are discharged through smoke discharging pipe in the combustion chamber, the water-filling body of heater is positioned at the upper end of combustion chamber, smoke discharging pipe and gas preheating pipe are spaced in the water-filling body of heater, the material heating plate communicates with the water-filling body of heater, the inside also has been full of water, the oven dry orifice plate that has a micropore is connected with the material heating plate and is positioned at its oblique lower end, the water-filling body of heater surrounds and forms drying chamber, and material heating plate and oven dry orifice plate are positioned at drying chamber.
When grain need be dried, the fire coal of ignition combustion chamber, open the fan blower that the cooling tower lower end connects, the material heating plate absorbs the heat energy that water discharges in the water-filling body of heater, temperature raises, grain flows to after the material heating plate carries out contact toaster from the feed opening that is positioned at drying chamber top, effect by self gravitation flows to again on the oven dry orifice plate, be subjected to from the gas drying of gas preheating pipe lower end outlet discharge, like this grain through the contact toaster gas drying that replaces several times after, passed through below the moisture content of safe storage, collect the discharge drying chamber by going out magazine, promoting office to cooling tower by grain cools off, grain packaging through cooling is stored, the air of the certain heat of band that discharge cooling tower upper end is entered the bottom of the oven dry orifice plate that is positioned at drying chamber again being blown into the preheating of gas preheating pipe through wireway end entrance from the gas preheating pipe under the effect of fan blower by the lower end outlet of gas preheating pipe.
The utility model is compared with existing foodstuff drying device, and the hydropneumatic drying rate is fast, and the waste heat second use can improve heat energy utilization rate 30%, temperature stabilization in the drying chamber, and the grain quality of oven dry is good, and cost of manufacture is low, and technology is simple, and is easy to maintenance.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A cutaway view of front view of the present utility model;
Fig. 3 is the schematic diagram of the waste heat second use of cooling tower of the present utility model.
Be positioned on the base (1) with reference to Fig. 1, Fig. 2, Fig. 3 combustion chamber (2), water-filling body of heater (3) is positioned at the upper end, combustion chamber, water-filling body of heater (3) surrounds the cavity that forms and constitutes drying chamber (5), smoke discharging pipe (4) and gas preheating pipe (9) are spaced in water-filling body of heater (3), the lower end of smoke discharging pipe (4) is communicated with combustion chamber (2), the upper end of gas preheating pipe (9) is communicated with the wireway (12) of cooling tower (13), and lower port inserts the bottom of drying chamber (5).Material heating plate (7) is communicated with water-filling body of heater (3), also has been full of water, and oven dry orifice plate (6) is connected the oblique lower end of material heating plate (7) and has micropore.
When grain need be dried, the fire coal that ignition combustion is indoor, smoke discharging pipe (4) Xiang Shuizhong in the water-filling body of heater (3) discharges heat energy, material heating plate (7) absorbs the heat in the water, temperature raises, open the fan blower (11) of cooling tower (13) lower end, gas enters gas preheating pipe (9) preheating through heat conduction tracheae (12), at this moment, grain flows on the material heating plate (7) from the feed opening (8) that is positioned at drying chamber (5) top, after carrying out contact toaster, carry out the gas oven dry in oven dry orifice plate (6) flowing to again under the effect of gravity, through the contact toaster that replaces several times, grain behind the gas drying has reached below the moisture content of safe storage, by going out magazine (10) collection and delivering to cooling tower (13) through the grain elevator and cool off also package storage, the air of the certain heat of band that discharges during cooling enters the last end entrance of gas preheating pipe (9) through wireway (12) under the effect of fan blower (11), carry out the second use of waste heat.
Claims (2)
1, hydropneumatic energy-saving grain warm air drier is by base (1), oven dry part and feed opening (8), go out magazine compositions such as (10), it is characterized in that: combustion chamber (2) connect as one with the drying chamber (5) that water-filling body of heater (3) is surrounded, smoke discharging pipe (4) is spaced in water-filling body of heater (3) with gas preheating pipe (9), material heating plate (7) is communicated with water-filling body of heater (3), also be full of water, the oven dry orifice plate (6) that has a micropore and material heating plate (7) are connected and are positioned at the oblique below of material heating plate (7), and grain heat-drying is to hocket through material heating plate (7) contact toaster with by the gas drying that outlet pass through of discharging in gas preheating pipe (9) lower end dried orifice plate (6);
