Abstract

The invention relates to a drying technique, can be used for drying cotton or rappas, allows to intensify the drying process and to regulate the heating surface. The solar collector consists of a set of sections 1, each of which contains several heat-absorbing elements and is reinforced by means of pipes 2 in the form of rigid trusses on a centrally located exhaust pipe 4, and the elements of sections 1 are interconnected by means of tubular ligaments fastened together by upper and lower hinges . The lower hinges, when drying cotton, are equipped with wheels 8, and when evaporating solutions, floats. The tubular ligaments are fixed on the pipe 4 by means of the upper 10 and lower 12 strings. The solar collector is made collapsible, easy to transport, since it is equipped with wheels, and allows you to adjust the heating surface by selecting the number of sections. 2 hp f-ly, 5 ill.

Figure 1 shows a solar collector for drying cotton, a general view; Fig. 2 shows a section of a solar receiver in a semi-folded form; on fig.Z - detailing frame mounts; on Fig.4 - the solar collector afloat, general view; Fig. 3 shows the fastening of the frame and the strings on a hinge at the base of the pipe, for example.

The glyphoprimer for drying cotton and also for extracting rapp using solar energy has the following form. A film coated solar collector is proposed to be manufactured sectionally. One section 1 has a frame made of pipes 2 in the form of rigid trusses on the sides, the ends of which converge at the lower hinge 3 at the base of the exhaust pipe 4. The consumption ends of the pipes 2 are connected by folding trusses, the tubular links 5 of which are connected the upper 6 and lower 7 hinges, while the hinges 7 rest on the forks with wheels 8. The hinges 6 are connected to the hub 9 by the upper strings 10, on which a transparent film 1.1 can be hung, and the lower strings 12, designed for fastening-40 thin near-surface layer, togni wire or layer assal black mesh 13. On the top hinge 14 of the bell 15, the upper links of the pipes 2 are movably fixed, and on the sleeve 9 - the ends of the upper strings 10. The bottom of the hinge 3 is under the bottom wall of the circular bell 15, which is the base Instead of wheels 8, floats 16 are installed afloat, and instead of a metal mesh, it is proposed to install a plastic one as more inert to a chemically active medium. Pipe 4 can be made of polyethylene

folding. Since the Solar receiver you-sg became possible in the presence of a film

full on the duct, the side walls 17 are also covered with a transparent film.

The solar receiver works as follows.

When folded, the helicopter can be delivered to the hirman (as a trailer, since there are wheels). A platform is being prepared for a solar receiver sweep, an exhaust system is installed (circular socket 15 with exhaust pipe 4 on it), pipes 2, upper strings 10 and lower strings 12 are fastened on the lower hinge 3, and the transparent film 11 and wire or plastic black mesh 13. At the site above which it is intended to deploy

5 The solar collector is laid out in a layer of 20-30 cm portion of cotton. Then the solar collector unfolds, and the grid should touch the cotton layer. The sun's rays, getting ck, take a film of crayfish, heat the mesh and with it the surface of the cotton layer. The air heated in the space between the mesh and the film under the action of the exhausting effect created with the power of the tube 4 begins to move over the surface of the heated cotton layer and carry out the evaporated moisture. In the absence of a grid, a drying effect also occurs, although not as

0 intense due to the considerable scattering of the sun's rays by the surface of the cotton layer.

In the case of using a solar collector on evaporating ponds of chemical plants 35, instead of wheels, floats 16 should be installed. In this case, the presence of a grid is necessary, and it should be submerged to a depth of no more than 2 cm for intensive heating.

Yes, the efficiency of the exhaust system increases by increasing the intensity of evaporation. In the process of cotton drying, the solar collector periodically folds and produces a trowel of cotton.

Thus, a solar collector for drying cotton, as well as for rappa extraction using solar energy, is transportable, it can be used not only for drying various agricultural products, but also for evaporation. Simplified technological processes (agitating and changing). it
