Abstract

The invention belongs to the technical field of drying of bulk materials, and particularly discloses a compartment type dryer. The compartment type dryer comprises a box body, an air damper, a heater and a tray, wherein an air inlet and an air outlet are formed in the box body; and the tray is a silk screen. The compartment type dryer is characterized by further comprising a fan and a ventilating duct, wherein one end of the ventilating duct is communicated with the air inlet; the other end of the ventilating duct is communicated with the air outlet; the fan is connected on the ventilating duct; a water absorbing device is arranged in the ventilating duct; the tray, the heater and the air damper are fixed in the box body; the air damper is positioned between the tray and the heater; and the heater and the air inlet are oppositely arranged. Hot air in the box body is recycled because of the ventilating duct, so that the heat utilization rate is high. The water absorbing device can effectively absorb water in hot air, so that humidity of hot air is kept within a proper range all the time, thereby increasing the drying effect.

Description

Tray dryer
Technical field
The invention belongs to dry discrete material technical field, particularly relate to a kind of tray dryer.
Background technology
Small-sized, also known as huge rock drier, is generally called baking oven by tray dryer, and large-scale is called drying room.Its cardinal principle is: by adding hot-air, makes cold air become hot-air, and hot-air, by material surface, is taken away the moisture in material, realized the dry run of material through heat and mass transfer process.
Application number is the patent of CN201310427795.X, disclose a kind of tray dryer, comprise casing, the top of casing is provided with exhaust outlet and motor, and motor is connected with the fan in casing, and described fan two is surveyed and is provided with heating tube, wall box is provided with air intlet, box house is provided with bracket, and bracket supports silk screen by strut, and bracket arranged outside has deep bead.Be placed on by material on silk screen, upper and lower surface all has hot blast to pass through, and accelerates the drying of material, and save drying time, its shortcoming is: cold air enters from air intlet, and the hot-air with a large amount of waste heat and humidity is discharged from exhaust outlet again, and heat utilization ratio is low.
Summary of the invention
The object of the present invention is to provide the tray dryer that a kind of heat utilization ratio is high.
In order to achieve the above object, the invention provides a kind of tray dryer, comprise casing, deep bead, heater and pallet, described casing is provided with air inlet and air outlet, described pallet is silk screen, wherein, also comprise blower fan and ventilation shaft, one end of described ventilation shaft is communicated with air inlet, the other end is communicated with air outlet, described blower fan is connected on ventilation shaft, water absorber is provided with in described ventilation shaft, described pallet, heater and deep bead are all fixed in casing, described deep bead is between pallet and heater, described heater and air inlet are oppositely arranged.
Principle of the present invention is: heater makes the air themperature in casing raise, become hot-air, blower fan then impels the hot-air in casing to circulate, with raw material to be dried in tray, moisture in raw material enters in hot-air, absorbed by the water absorber in ventilation shaft, hot-air continues to enter in casing and repeats after heater via drying to carry out drying to raw material.
Beneficial effect of the present invention is: because in casing, the humidity of air is larger, easily there is the faults such as conduction or short circuit in the fan in traditional tray dryer, adopt blower fan to replace traditional motor to add the combination of fan, decrease the fault rate of equipment, add the security performance of equipment.Ventilation shaft makes the hot air circulate in casing use, and the utilization rate of heat is high.Water absorber then can, effectively by the moisture absorption in hot-air, make the humidity of hot-air remain at suitable scope, thus adds dry effect.
Further, described water absorber is fiber desiccant, and the external diameter of described fiber desiccant equals the external diameter of ventilation shaft, and fiber desiccant is provided with air vent.Fiber desiccant has good soaking effect, can cut arbitrarily or be die-cut into various shape, conveniently load in ventilation shaft, and air vent then makes air smoothly by fibre dryer, avoid fiber desiccant to block ventilation shaft.
Further, described water absorber is packed silica-gel desiccant, and described packed silica-gel desiccant is hung on ventilation shaft inwall.Silica-gel desiccant has higher temperature tolerance, and when hot air temperature is higher, the drying effect of silica-gel desiccant is better.
Further, the outer wall of described casing and ventilation shaft is provided with heat-insulation layer.Heat-insulation layer can distribute by the heat effectively reduced in casing, adds the utilization rate of heat.
Further, described heat-insulation layer is that high temperature resistant heat insulation is cotton, and high temperature resistant heat insulation cotton has the feature of low heat conductivity, low specific heat capacity, and heat insulating effect is given prominence to.
Further, described heater is heating tube, and it is little that heating tube has volume, the feature that heating effect is high, and energising can be heated, and heating effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of tray dryer embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: casing 1, heating tube 2, deep bead 3, pallet 4, ventilation shaft 5, air blast 6, heat-insulation layer 7, water absorber 8.
As shown in Figure 1, the present embodiment provides the tray dryer that a kind of heat utilization ratio is high, comprise casing 1, heating tube 2, deep bead 3, pallet 4 and ventilation shaft 5, casing 1 is provided with chamber door, the outer wall of casing 1 is coated with heat-insulation layer 7, heat-insulation layer 7 is made up of high temperature resistant heat insulation cotton, and the outer wall of heat-insulation layer 7 is arranged with reinforcement, for fastening heat-insulation layer 7.Be welded with tray rack in casing 1, pallet 4 is silk screen, and is arranged on tray rack.Deep bead 3 is welded in casing 1, and heating tube 2 is arranged on the bottom of casing 1, and deep bead 3 is between heating tube 2 and pallet 4.
The top of casing 1 is provided with air inlet, and bottom is provided with gas outlet, and ventilation shaft 5 is communicated with casing with gas outlet by air inlet.Air blast 6 is arranged on ventilation shaft 5, for blasting air in casing 1.The outer wall of ventilation shaft 5 is coated with heat-insulation layer, is filled with water absorber 8 in the pipe of ventilation shaft 5, water absorber 8 is made for fiber desiccant, and fiber desiccant offers the air vent passed through for air, avoids fiber desiccant to block ventilation shaft.
During specific works, open chamber door, raw material to be dried is put on pallet 4, shuts chamber door, connect heating tube 2, after preheating 2-5 minute, open air blast 6.Heating tube 2 makes the air themperature in casing 1 raise, become hot-air, air blast 6 impels the hot air circulate in casing 1 to circulate, with raw material to be dried in tray 4, moisture in raw material enters in hot-air, absorbed by the fiber desiccant in ventilation shaft 5, hot-air continues to enter in casing 1 and repeats to carry out drying to raw material after heating tube 2 drying.In order to save electric energy, can at interval of after 20 minutes startup air blast 6 five minutes, avoid air blast 6 continuous firing.Periodic replacement fiber desiccant, to ensure the drying effect of this device.In addition, when raw material to be dried needs higher baking temperature, then fiber desiccant can be replaced by packed silica-gel desiccant, packed silica-gel desiccant be hung in ventilation shaft 5.
