Abstract
A negative pressure drying machine comprises a box, a motor, a vacuum machine and a rotator, wherein the bottom of the box is fixedly connected with the motor, the top of the motor is connected with the rotator, heaters fixedly connected with the inner wall of the box are arranged around the rotator, one side of the top of the box is hinged to an upper cover through a column body, the other side of the top of the box is connected with the upper cover through a lock catch, and the top of the upper cover is connected with the vacuum machine through an exhaust pipe. The negative pressure drying machine has the advantages that the structure is simple; the vacuum machine is additionally arranged on the sealed drying box, so that air pressure inside the box is lowered and the evaporation speed of water is greatly improved; the negative pressure drying machine can be suitable for drying machining of articles not resisting to high temperature, and is high in working efficiency, low in use cost and easy to popularize.
Description
Technical field
The present invention relates to a kind of negative pressure dryer.
Background technology
Drying plant, the technology of a comparative maturity at last in the machinery industry of China, but along with the development of society, client is when buying drying plant, more and more higher to the requirement of equipment, automaticity, environmental assessments etc. are all put on agenda, and client more and more payes attention to these problems, and the technical staff of our China Telecom is while guaranteeing the quality of production, drying plant is carried out constantly research and development and improved, guarantees that the progress and development of society is got caught up in the manufacture of drying plant.
Domestic in design dryer flight structure, analytical structure parameter, Zhou Sichang (1985) contrasts seven type flights and carries out maximum angle of discharge research, designs shaped form flight.Move in cylinder for material, can not drop on uniformly in whole cylinder, cause the problem that filling rate is too low, during Wang Wen Zhou Qi studies, analytically derive and obtain particle at the slip of flight endoparticle deposition surface, discharge process; Devise three arcs with specific unloading characteristics with this to copy and pull, overcome above-mentioned shortcoming: and measure three arc flights discharging distribution in the horizontal of its design by experiment.Show with the contrast of experimental data, sliding to particle in its research draws off the mathematical description of process and actual conditions have the very high goodness of fit, but this model is more complicated, and amount of calculation is very large.
The domestic research in recent years also had material movement in cylinder and the time of staying.Li Shui waits clearly people to city Pu's rubbish having carried out a series of Cold simulating test without course of conveying in the rotary kiln of flight, and utilize statistical average analysis and stressed vector analysis to have studied movement of particles in cylinder, establish mean residence time and the volume flow rate model of simplification.
Traditional dryer is generally normal pressure or higher than normal pressure at its working environment air pressure, the speed of water evaporation is general, improve drying efficiency, the method adopted is generally improve dryer temperature and strengthen gas circulation, improve dryer temperature easily to make to be damaged by drying article, when being fine granularity by drying object, strengthening gas circulation and can cause being splashed by drying object, can not meet the requirement of modern people, the technology being therefore badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of negative pressure dryer.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of negative pressure dryer, comprise casing, motor, vacuum machine and circulator, described bottom half is fixedly connected with motor, described motor top connecting rotator, the heater being fixedly connected with cabinet wall is provided with around described circulator, side, described casing top is by the hinged upper cover of cylinder, and described casing top opposite side connects upper cover by snap close, and described upper tops connects vacuum machine by exhaust tube.
Described circulator is reticulated metal structures.
Described motor is waterproof machine.
The invention has the beneficial effects as follows: structure is simple, the oven dry casing of sealing installs vacuum machine additional, the air pressure of box house is reduced, greatly accelerate evaporation of water speed, be applicable to the oven dry processing of non-refractory object, operating efficiency is high, use cost is lower, is easy to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, casing, 2, cylinder, 3, snap close, 4, upper cover, 5, exhaust tube, 6, vacuum machine, 7, motor, 8, circulator, 9, heater.
Detailed description of the invention
A kind of negative pressure dryer as shown in Figure 1, comprise casing 1, motor 7, vacuum machine 6 and circulator 8, motor 7 is fixedly connected with bottom casing 1, motor 7 top connecting rotator 8, the heater 9 being fixedly connected with casing 1 inwall is provided with around circulator 8, side, casing 1 top is by the hinged upper cover 4 of cylinder 2, casing 1 top opposite side connects upper cover 4 by snap close 3, upper cover 4 top connects vacuum machine 6 by exhaust tube 5, circulator 8 is reticulated metal structures, motor 7 is waterproof machine, structure is simple, the oven dry casing of sealing installs vacuum machine additional, the air pressure of box house is reduced, greatly accelerate evaporation of water speed, be applicable to the oven dry processing of non-refractory object, operating efficiency is high, use cost is lower, be easy to promote.
