Description

Triple channel particle drying device

Technical field

The utility model relates to the drying equipment of Flakeboard Product Line, a kind of triple channel particle drying device of saying so more specifically.

Background technology

Particle drying is that particieboard is produced very important together operation on the flowing water.For particle drying, the institute of production firm of at present domestic particieboard generally use be the particle drying device, what existing flake drying process adopted is extended type single channel drying machine, its principle is that the hot-air that hot-blast stove produces is introduced in the single straight cylindrical channel by air-introduced machine, the passage cylinder goes out by blanking device in import material is mixed with hot-air, hot-air flows with definite value speed in barrel, line speed before wood shavings increase gradually along with the reduction of moisture content.Because machine only has a passage, in order to reach the required material water ratio of technology, so the passage roller must design very longly, so just can make wood shavings that enough heat exchanger times are arranged in cylinder, make the manufacture difficulty of machine strengthen, the installation floor space is big, the transportation difficulty.And owing to have only a passage, hot-air flows with constant speed in passage, and the preceding line speed of material does not only reduce with the reduction of moisture content, and is to accelerate gradually, so cause dried wood shavings water ratio uniformity to be difficult to obtain assurance, the particieboard quality that influence finally is processed into.

The utility model content

The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of floor space little, and can make the fully dry a kind of triple channel particle drying device of wood shavings.

For solving above-mentioned technical problem, the utility model by the following technical solutions:

Triple channel particle drying device of the present utility model, comprise drying machine, air inducing power set and cyclone separator, charging aperture is arranged on the drying machine, discharging opening is arranged on the cyclone separator, discharging opening is provided with rotary valve, drying machine, air inducing power set and cyclone separator are interconnected by pipeline, described drying machine is the outer cylinder by three descending suits, middle cylinder, inner cylinder and supporting and mounting bracket are formed, and outer cylinder, middle cylinder, the axis of inner cylinder overlaps, the inner cylinder inner chamber is communicated with by the inner chamber of middle cylinder and the inner chamber of outer cylinder, outer cylinder just, middle cylinder, gap between the inner cylinder constitutes folding passage, wood shavings can flow on passage, outer cylinder is connected with cyclone separator by pipeline, and air inlet is arranged on the inner cylinder, and hot-air is entered by air inlet.

Further technical scheme is: the corner of the corner of described inner cylinder and middle cylinder and middle cylinder and outer cylinder is provided with deflector, is detained in cylinder channel to prevent large stretch of wood shavings.

Further technical scheme is: described inner cylinder, middle cylinder and outer cylinder are to be welded by heat-resisting steel sheet and plate.

Further technical scheme is: described air inducing power set are electronic air-introduced machines.

Compared with prior art, the beneficial effects of the utility model are: the triple channel structure of drying machine under the effect of electronic air-introduced machine, can make hot-air fully contact with wood shavings.Porch at cylindrical shell is introduced wood shavings by rotary valve, because the air quantity of air-introduced machine is fixed, and the varying in size of three cylinders, so the speed difference of air velocity in three passages, inner core is fastest, intermediate cylinder takes second place, outer cylinder is the slowest, make very fast relatively dry eliminating of relatively little and thin wood shavings, otherwise big and thick wood shavings can stop the longer time in passage then, to guarantee sufficient heat exchange, thereby guaranteed the uniform moisture content of dried wood shavings, the deflector in the cylinder can guarantee that the flake operation is unobstructed, reduces and is detained, eliminated disaster hidden-trouble, triple channel particle drying device volume of the present utility model is less simultaneously, and convenient transportation is simple in structure, be suitable for suitability for industrialized production, be easy to promote.

Description of drawings

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

Fig. 2 is the A-A ' cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 1, shown in Figure 2, triple channel particle drying device of the present utility model, be by drying machine 1, electronic air-introduced machine 6 is formed with cyclone separator 2, wherein on the drying machine 1 charging aperture 4 is arranged, discharging opening 3 is arranged on the cyclone separator 2, discharging opening 3 is provided with rotary valve, drying machine 1, electronic air-introduced machine 6 and cyclone separator 2 are interconnected by pipeline, on the electronic air-introduced machine 6 exhaust outlet 7 is arranged, described drying machine 1 is to be welded by three heat-resisting steel sheet and plates, the outer cylinder 13 of descending suit, middle cylinder 12, inner cylinder 11 is formed with supporting and mounting bracket, and inner cylinder 11, middle cylinder 12 overlaps with the axis of outer cylinder 13, and the gap between them constitutes folding passage; The corner of inner cylinder 11 and middle cylinder 12 and in the corner of cylinder 12 and outer cylinder 13 be provided with deflector 8, and outer cylinder 13 is connected with cyclone separator 2 by pipeline, inner cylinder 11 is provided with air inlet 5.

As shown in Figure 1, at first enter in the inner cylinder 11 in the drying machine cylinder 12 and outer cylinder 13 in entering successively again under the moist rotary valve effect of wood shavings on charging aperture 4; Wood shavings promptly obtain dry wood shavings separating the back by the discharging opening eliminating through entering cyclone separator 2 by pipeline behind the folding passage of being made up of three

cylinders

11,12,13 under the effect of electronic air-introduced machine 6.
