Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is carried out detailed for example, but can not use
The preferred embodiment limits the protection scope of the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of drying equipment, and bracket 7 is equipped on electronic balance 6,
It is equipped with pallet 5 on bracket 7, sample is contained in pallet 5, electronic balance 6 is used to measure the quality of the sample, in which:
The pedestal of the electronic balance 6 is connect by shaft 8 with upper cover 9, and the upper cover 9 can be rotated around the shaft 8,
It can be rotated between open position and lid coincidence are set, there is the cavity being recessed upwards, when the upper cover 9 is located in upper cover 9
When lid coincidence is set, the pallet 5 can be covered, and form airtight heating chamber 10, the heating chamber 10 with the electronic balance 6
It is to be made of the cavity of sunken formation concave up in the upper cover 9；In order to improve leakproofness, sealing is equipped in the opening of upper cover 9
Pad 3；
Corresponding to heating tube 2 is equipped at the top of the pallet 5 in the upper cover 9, for being carried out to the sample in pallet 5
Drying；
The upper cover 9 is additionally provided with air curtain device 1, and the air curtain device 1 has towards the gas outlet 101 inside upper cover 9, institute
It states air curtain device 1 and is connected to positive nitrogen；9 roof of upper cover, which corresponds to, is equipped with gas vent 11 above the pallet 5.
In preferable situation, the height of the gas outlet 101 is between pallet 5 and the heating tube 2, and along level side
To outlet；So, the nitrogen of the positive pressure sprayed in the gas outlet 101 of air curtain device 1 will be between pallet 5 and heating tube 2
Air does not stop to stir, and can form Convective Heating.Outlet pipe in air curtain device 1 towards gas outlet 101 can choose summary
It tilts or with some radians, it is possible thereby to form annular circulating air duct, is more advantageous to gas between pallet 5 and heating tube 2
Flowing.
In addition, the total cross-sectional area of the gas vent 11 is preferably 1 to five/10th point of the upper surface area of pallet 5
One of；It so, will not be immediately from gas vent 11 by the nitrogen with positive pressure sprayed in the gas outlet 101 of air curtain device 1
Discharge, but the sufficiently long residence time is generated in airtight heating chamber 10, help Convective Heating material and then in company with material
In include aqueous vapor airtight heating chamber 10 is discharged together, improve heating efficiency, also improve drying efficiency.
In addition to this, the upper cover 9 can also be set using the structure that straight line is gone up and down in open position and the lid coincidence
Between move, reach same technical effect, it will not be described here.
When the utility model uses, material is placed on pallet 5 is weighed by electronic balance 6, and then upper cover 9 rotates
It is set to lid coincidence, air curtain device 1 starts to be filled with nitrogen into upper cover 9, outlet in the horizontal direction under 101 preferable case of gas outlet,
And it is higher than 5 certain distance of pallet, pallet 5 or material are blown to avoid nitrogen；Air after one section of duration, in 9 cavity of upper cover
It is discharged by gas vent 11, oxygen is thin enough, then starts heating tube 2 and starts to dry, is also ceaselessly filled with during the drying process
Nitrogen, to form gaseous exchange in lid, make heating tube 2 to material while carry out radiant heating and Convective Heating, substantially
Degree improves heating efficiency, saves drying time；Moreover, because being in anaerobic state in upper cover 9, material is also avoided by high temperature oxygen
The case where change, occurs, it is clear that sample oxidation is other than being filled with nitrogen in order to prevent, it is also an option that inert gas；Drying is completed
Afterwards, the material after opening upper cover 9 is dried to open position, 6 amount of electronic balance, can calculate the water content of material.For not
The drying that the sample (material) that perhaps measurement accuracy is of less demanding can be oxidized can select at this time be passed through positive pressure air or its
His gas changes heating method, reaches and improves heating efficiency, without being filled with the nitrogen or inert gas of higher cost.
Cause equipment to be damaged or sample (such as: coal sample) burning in order to avoid drying temperature is excessively high, is additionally provided on pallet 5
Temperature inductor 4, when the temperature is excessively high, the temperature inductor 4 can issue alarm signal, controller control sound to controller
Light device issues alarm signal, interrupts drying procedure.Wherein controller and acoustic optical devices belong to the prior art.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, without departing from the spirit and scope defined by the claims, can many modifications may be made, variation or equivalent, example
It is passed through the type of gas as changed as needed, but falls within the protection scope of the utility model.
