Description

A kind of particle drying device

Technical field

The utility model belongs to technical field of drying, is specifically related to a kind of particle drying device.

Background technology

While being graininess due to material and extraneous contact area maximum, add artificial maintenance improper, easily make it owing to having absorbed airborne large quantity of moisture, cause humidity excessive, affect its follow-up use.Traditional pellet dryer operation principle is, by adding hot-air, the material heating in hopper is removed to the moisture in material, but particle is over-drying, also can cause it should inevitably mutually collide contact and cracking pulverizing, enterprise is caused to very large economic loss, on the pollution of environment, also there is certain impact in the gas of meanwhile, discharging in dry run.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of particle drying device, and this device can effectively be dried granular material, can meet the humidity requirement of this material again simultaneously.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of particle drying device, comprise tank body, exhaust passage, drying chamber, driving shaft, motor, air heating apparatus, air blast and collecting tank, the cross section of tank body is cylindric, exhaust passage is fixed on the center of top of tank body, the outer cover of tank body is provided with insulation sleeve, tank body has some through holes corresponding to the position of insulation sleeve, drying chamber is fixedly connected with driving shaft, driving shaft is connected with Motor Drive, motor is fixed on the side of tank body, drying chamber is also provided with humidity sensor, humidity sensor is electrically connected to the controller that is positioned at this drying device outside, the bottom of insulation sleeve is communicated with the gas outlet of air heating apparatus, the air inlet of air heater is connected with air blast.

Further, above-mentioned drying chamber comprises external annulus and internal ring wall, between external annulus and internal ring wall, by polylith dividing plate, is connected, and external annulus and dividing plate all have the aperture that some apertures are less than grain diameter to be dried, and internal ring wall is fixedly connected with driving shaft.

Further, the outer shroud radius in above-mentioned drying chamber cross section is less than the radius in tank body cross section.

Further, above-mentioned air heating apparatus is a plurality of, and each air heating apparatus is connected with air blast respectively.

Further, above-mentioned exhaust passage is arranged with condensing unit, and is connected with collecting tank, and the delivery port of collecting tank is connected with the inlet of liquid heating, the steam (vapor) outlet of liquid heating is communicated with insulation sleeve by control valve, and liquid heating and control valve are all electrically connected to controller.

The utility model has the advantages that: this drying device can to granular material guarantee under the prerequisite of humidity fully dry, and in dry run, effluent air can be recovered utilization, on environment without impact, meet green requirement of producing, this drying device is simple in structure simultaneously, it is convenient to control, and has greatly saved man power and material.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of drying chamber in the utility model.

Wherein, 1, tank body, 2, exhaust passage, 21, condensing unit, 3, insulation sleeve, 4, drying chamber, 41, dividing plate, 5, motor, 51, driving shaft, 6, air heating apparatus, 61, liquid heating, 7, air blast, 8, collecting tank.

The specific embodiment:

As shown in Figure 1 to Figure 2, a kind of particle drying device, comprise tank body 1, exhaust passage 2, drying chamber 4, driving shaft 51, motor 5, air heating apparatus 6, air blast 7 and collecting tank 8, the cross section of tank body 1 is cylindric, exhaust passage 2 is fixed on the center of top of tank body 1, the outer cover of tank body 1 is provided with insulation sleeve 3, and tank body 1 has some through holes corresponding to the position of insulation sleeve 3, drying chamber 4 comprises external annulus and internal ring wall, between external annulus and internal ring wall, by polylith dividing plate 41, be connected, external annulus and dividing plate all have the aperture that some apertures are less than grain diameter to be dried, internal ring wall is fixedly connected with driving shaft 51, and the radius of external annulus is less than the radius in tank body 1 cross section, driving shaft 51 drives and is connected with motor 5, motor 5 is fixed on the side of tank body 1, drying chamber 4 is also provided with humidity sensor, humidity sensor is electrically connected to the controller that is positioned at this drying device outside, the bottom of insulation sleeve 3 is communicated with the gas outlet of air heating apparatus 6, air heating apparatus 6 is a plurality of, the air inlet of each air heater 6 is connected with air blast 7 respectively, exhaust passage 2 is arranged with condensing unit 21, and be connected with collecting tank 8, the delivery port of collecting tank 8 is connected with the inlet of liquid heating 61, and the steam (vapor) outlet of liquid heating 61 is communicated with insulation sleeve 3 by control valve, and liquid heating 61 and control valve are all electrically connected to controller.
