A kind of high efficiency drying machine
Technical field
The present invention relates to a kind of drying plant, specifically a kind of bake out temperature is high, drying efficiency is high and high efficiency drying machine that can vacuum drying.
Background technology
Modulation process and activated carbon preparation field at pitch usually need to come drying material, semi-finished product or finished product with dryer.At present common dryer is used in use dry body of heater and rotates by driven by motor, and material simultaneously to be dried slides and is subjected to heated drying along the inwall of body of heater along with the rotation of body of heater.Aforesaid way makes the motion mode of material to be dried single, is heated inhomogeneous and causes drying effect poor, can't reach the effect of anticipation; And the body of heater of common drying machine is by 304 stainless steel manufacturings, and heat-resisting 400 ℃ at most, heat resisting temperature is low.
Summary of the invention
The objective of the invention is the defective that exists for existing equipment, provide that a kind of bake out temperature is high, drying efficiency is high and high efficiency drying machine that can vacuum drying.
The objective of the invention is to solve by the following technical programs:
A kind of high effective drier, comprise burner hearth body and body of heater, it is characterized in that the body of heater two ends employing support roller support that described body of heater is horizontally set in the burner hearth body and stretches out the burner hearth body, support roller contacts with rolling ring on body of heater and is connected and an end of body of heater is connected with the output of variable speed electric motors, particularly by transmission mechanism, one end of body of heater is provided with feed pipe and feed pipe is provided with valve, and the other end of body of heater adopts the sealing plate sealing; Be provided with the helicla flute that radially arranges along body of heater and the stirring bar that axially arranges along body of heater in described body of heater, the burner hearth body is provided with the hot air inlet that is connected with extraneous thermal source.
Described stirring bar evenly is arranged in body of heater.
Described burner hearth body adopts refractory brick and heat-insulation layer to make from the inside to the outside.
Described burner hearth body is provided with chimney.
Establish temperature-sensing probe on described burner hearth body.
Described body of heater is connected with vacuum extractor by the swivel joint that arranges on sealing plate.
Described transmission mechanism adopts chain drive.
Described valve adopts high-temperature ball valve.
The present invention has the following advantages compared to existing technology:
The present invention stirs material by helicla flute and stirring bar are set in body of heater, make the material movement direction changeable and be heated evenly, can make oven dry evenly, drying effect is more excellent, drying efficiency is higher; Body of heater, helicla flute, stirring bar are made by heat resisting steel 310S simultaneously, heatproof is up to 950 ℃, in addition by the swivel joint that is connected with vacuum extractor is set, when being aided with condition of high vacuum degree, the body of heater external heat can reach vacuum drying, make the material can oxidation, be fit to the cleaning and drying of the special materials such as battery material.
Simple in structure, easy to use and good drying effect that the present invention has, the characteristics that cost is low, suitable promoting the use of.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
as shown in Figure 1: a kind of high effective drier, comprise the body of heater 2 that adopts from the inside to the outside burner hearth body 1 that refractory brick 13 and heat-insulation layer 14 make and heat resisting steel 310S to make, burner hearth body 1 is provided with chimney 15 and temperature-sensing probe 16, body of heater 2 is horizontally set in burner hearth body 1 and stretches out body of heater 2 two ends employing support rollers 3 supports of burner hearth body 1, support roller 3 contacts with rolling ring 4 on body of heater 2 and is connected and an end of body of heater 2 is connected with the output of variable speed electric motors, particularly 6 by the transmission mechanism 5 of making, one end of body of heater 2 is provided with feed pipe 7 and feed pipe 7 is provided with the valve 8 that high-temperature ball valve is made, the other end of body of heater 2 adopts sealing plate 9 sealings and body of heater 2 to be connected to realize vacuum drying with vacuum extractor by the swivel joint 17 that arranges on sealing plate 9, for strengthening the changeable of the material direction of motion, be provided with the helicla flute 11 that radially arranges along body of heater 2 and along the axial stirring bar 12 of settings of body of heater 2, stirring bar 12 evenly is arranged in body of heater 2 in body of heater 2, burner hearth body 1 is provided with the hot air inlet 10 that is connected with extraneous thermal source so that the oven dry thermal source to be provided in addition.
The present invention is by stirring materials at interior helicla flute 11 and the stirring bar 12 that arrange of body of heater 2, makes the material movement direction changeable and be heated evenly, can make oven dry evenly, drying effect is more excellent, drying efficiency is higher; Body of heater 2, helicla flute 11, stirring bar 12 are made by heat resisting steel 310S simultaneously, heatproof is up to 950 ℃, in addition by the swivel joint 17 that is connected with vacuum extractor is set, when being aided with condition of high vacuum degree, body of heater 1 external heat can reach vacuum drying, make the material can oxidation, be fit to the cleaning and drying of the special materials such as battery material; Have simple in structure, easy to use and good drying effect, characteristics that cost is low, suitable promoting the use of.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of doing on the technical scheme basis is within all falling into protection domain of the present invention; The technology that the present invention does not relate to all can be realized by prior art.
