Specific embodiment

As shown in Figures 1 to 4, a kind of sawdust vacuum dryer, including a Drying 11, the Drying are existing skill Art, the Drying front end upside are equipped with feed inlet 12, and discharge port 14 is equipped on the downside of Drying tail end, is turned in the Drying It is dynamic to be connected with auger 22, the movement for being placed on material in Drying is able to drive by the rotation of auger, which can be particle Material, rod-like material etc., material is moved to discharge outlet under the drive of auger at feed inlet.The discharge outlet is connected with down The equipment of one process.

It is equipped with manhole 13 in Drying tail end, the maintenance for carrying out equipment is entered for people.

It is connected with negative pressure mechanism at the manhole, the air in Drying is extracted by negative pressure mechanism, so that in Drying Air pressure is negative pressure, and moisture fusing point boiling point under negative pressure state is all reduced with the raising of vacuum degree in material, and this design is logical Cross the reduction for reducing air pressure to realize moisture boiling point in Drying.

The negative pressure mechanism can be vacuum pump.

Motor 21 is installed in Drying front end, the motor is connected with auger, is equipped with fixing seat in Drying tail end 24, the fixing seat is connected with auger 22 by connecting shaft 23.

Scheme refinement, the fixing seat outside are equipped with outer cover plate 25, material, dust are avoided to enter bearing.

A strainer 31 is equipped on the upside of Drying, described strainer one end is connected with feed inlet, and the other end is connected with manhole, institute It states between on the upside of strainer and Drying and forms an arc-shaped cavity, multiple diversion pipes 32, the diversion pipe are installed on the strainer On be connected with left arc plate 33 and backarc plate 34, form one between adjacent left arc plate and right arc plate and pass through convenient for hot gas, vapor Air intake 35, vapor can be back in diversion pipe 32 along left arc plate, right arc plate inner wall, and more diversion pipes pass through a mainstream Pipe is connected, and the water that condensation is formed is guided in the external world.

The effect of strainer is that the first mounting body as diversion pipe, left arc plate, right arc plate is realized and fixed；Second permits Avoid material to enter air intake from this while hot gas, vapor enter perhaps, third formed after passing through the filter screen certain temperature difference, More easily carry out the condensation of vapor.

In order to accelerate to condense, described arc-shaped cavity one end is connected with air inlet pipe 61, and the other end is connected with escape pipe 62.Institute Blower or air pump can be connected with by stating air inlet pipe, and escape pipe is connected with the external world.Air is injected by blower, because air is normal The hot gas temperature difference in temperature, with Drying is larger, so that vapor is condensed, and takes the external world out of by escape pipe.And hot gas and water is steamed Gas can only enter arc-shaped cavity by air intake, under the action of high-speed flow, can form negative pressure at air inlet, further decrease Air pressure in Drying.

As seen in figures 2 and 3, first movement ring 41 and the second shift(ing) ring 42, first movement ring 41 are socketed on Drying It is arranged in parallel with the second shift(ing) ring 42.Heating module 43 is mountable between first movement ring and Drying left side wall, Huo Zhe Between one shift(ing) ring 41 and the second shift(ing) ring 42, or between the second shift(ing) ring and Drying right side wall.

The heating module is electric heating assembly.

The heating method of the electric heating assembly is resistance heating, induction heating, electric arc heated, electron beam heat, are infrared Line heating or medium heating.

Electric heating assembly is very common in daily life, such as resistance wire energization, vortex induction heating etc..

By the different location in two shift(ing) rings, one group or multiple groups heating module are set, it can be achieved that temperature accurate control System.By adjust two shift(ing) rings different location, can adjust three subregions different temperatures, it is assumed that three subregions all There is one group of heating module, if two sides subregion is small, intermediate partition is big, then the hot gas in unit volume, intermediate partition is less than two Side subregion.

By the zoning design of shift(ing) ring, it can be achieved that the control of different temperatures, while guaranteeing temperature, so that Drying It is interior to form the hot cold wind with certain temperature difference, material is conveniently taken out of using the internal flow of air in the rotation by means of auger In steam.

Scheme refinement, the shift(ing) ring can be locked on Drying by bolt, or directlyed adopt welding and realized fixation On Drying.

Except for the technical features described in the specification, it all is technically known to those skilled in the art.
