Description

The invention relates to technological processes for the preparation of animal feed, in particular to devices for the ultraviolet processing of animal feed, components of feed mixtures.

A known installation for processing stale grain with ultraviolet rays (Rubtsov V.A., Osetrov P.A., Bondarenko S.P., Savinkov K.P. Application of electric energy in agriculture. - M .: Kolos, 1964, S. 447 -448 - analogue), containing the installation for washing grain, dryer, elevator, sieves, bactericidal lamps, cameras for irradiation.

The disadvantage of this device is the low radiation efficiency due to the inability to uniformly irradiate the material being processed due to the presence of several screens and a large number of radiation sources.

A device is known for irradiating products with ultraviolet radiation (US Patent No. 4,776,267, MKI ⁴ A 23 L 3/26, 1988 - analogue), comprising a storage device, a conveyor, an irradiation chamber, UV lamps, an oscillating platform, a receiver of the processed product.

The disadvantage of this device is also the low radiation efficiency, since there is no necessary constant monitoring of the quality of radiation due to the deterioration (in time) of the characteristics of the optical elements of the irradiators.

A well-known line of feed irradiation (Novikov N.N., Kovalev I.I., Kisenko I.G. // Engineering in agriculture, 1983, No. 2, p.17 - prototype), containing a filling pit, elevator, hopper, screw , drum, irradiator with UV radiation sources, discharge tray, mixer, pump, feed pipe. In this case, the irradiation unit has a frame on which four support rollers are mounted, and the drum has guides with which it rests on the rollers.

The disadvantage of this line is that the constant angle of inclination of the drum along the vertical axis complicates the process of unloading the processed material and does not allow to evenly distribute the processed material on the surface of the drum, and the stationary placement of the UV radiation source over the irradiated material does not allow you to set different processing modes. In this case, the UV radiation source is not able to produce a relatively constant radiation flux due to the fact that it is exposed to a dusty environment created by the processed material with stirring inside the drum. All of the above makes the process of irradiation of bulk materials ineffective.

The objective of the invention is to increase the efficiency of irradiation of feed by ensuring uniform distribution of the flux of the UV radiation source over the irradiated material.

The technical result is achieved by the fact that, unlike the prototype, the feed irradiation unit has a pit, a vertical elevator, a hopper, a screw conveyor, a drum with a frame and support rollers, an irradiator with UV radiation sources, an unloading tray, a mixer, a pump, a feed line, moreover it is equipped with a base made of movable and fixed parts, while the drum has a cover with the ability to tilt along the vertical axis at an angle of 0-16 ° by means of support rollers, which are placed on a shaft attached with An end to the movable part of the base, which has an adjusting screw, and an irradiator with a UV radiation source is located inside the drum and is mounted to move horizontally in two directions by means of a support axis made in the form of an endless screw, one end of which abuts against the drum cover and the other is articulated with the electric motor of its drive, and the irradiator is equipped with a protective glass with a frame containing a brush installed with the possibility of movement due to movable stops fixed to it on both sides, operating with the walls of the drum, and attached using telescopic rods to a guide ring worn on the support axis.

Figure 1 presents a view of the General installation for irradiating feed, figure 2 - feed - front view, figure 3 feed - left view, figure 4 feed - bottom view.

Installation for irradiation of feed consists of a pit 1 (Fig. 1) with material 2 intended for processing, vertical elevator 3, hopper 4, screw conveyor 5, drum 6, made with the possibility of inclination along the vertical axis at an angle of 0 ... 16 ° by means of support rollers 7, which are placed on the shaft 8 through a pulley 9 with a drum drive motor 10. The base of the installation is made of two parts: the movable part 12 and the stationary 13, moreover, the shaft 8 is fixed with bearings 11 to the movable part of the base 12. Regulation of the movable parts about Foundation 12 is carried out using the adjusting screw 14 mounted on the fixed part 13 of the base. In addition, the drum 6 includes lids 15 connected to the mounting frame 16 mounted on the movable part of the base 12 and technological holes 17 for loading and unloading the processed material 2. The irradiator 18 with UV radiation sources 19 is located inside the drum 6 and is mounted for movement along horizontally in two directions by means of a support axis 22, made in the form of an endless screw, one end of which abuts against the cover 15 of the drum 6, and the other is articulated with an electric motor 23 of its drive. In this case, the irradiator 18 contains ballast equipment 24 (Fig. 2) and is equipped with a protective glass 25 with a frame 26 containing a brush 27 (Figs. 3, 4), mounted with the possibility of movement due to movable stops 28 connected to it from two sides, interacting with the walls of the drum 6, and attached using telescopic rods 20 to the guide ring 21, worn on the support axis 22. Installation for irradiation of bulk materials also contains an unloading tray 29, a mixer 30, a pump 31 and a feed pipe 32.

Installation for irradiating feed is as follows. From the overburden pit 1 (Fig. 1), the material 2 intended for processing is fed by means of a vertical elevator 3 to the hopper 4 and then by means of a screw conveyor 5 into the drum 6, which starts to rotate. At the same time, the irradiator 18 with UV radiation sources 19 installed inside the drum 6 is turned on. During processing, the irradiator 18 moves over the material 2 intended for horizontal processing in two directions by means of a support axis 22 made in the form of an endless screw. During rotation, one end of the support axis 22 abuts against the cover 15 of the drum 6, and the other is articulated with a reversible electric motor 23 of the drive of the support axis 22, which allows the support axis 22 to be rotated clockwise / counterclockwise. The height of the suspension of the irradiator 18 above the material being processed 2 is pre-adjusted using telescopic rods 20. When the irradiator 6 is moved along the support axis 22 to the extreme positions (left or right), the movable stops 28 come into contact with the walls of the drum 15 and begin to move the brush 27 fixed in the frame 26 (figure 2). When this dust deposits deposited on the protective glass 25, showered down. Moreover, the angle of inclination of the drum 6 α is preset in the range from 0 ° to 16 ° by extending the adjusting screw 14, which allows thereby creating the best conditions for mixing the processed material 2. After irradiation, the processed material 2 is poured through the technological hole 17 of the drum 6 into the unloading tray 29 and then it enters the mixer 30, where it is mixed with water, and in the form of a paste is supplied by means of a pump 31 to the feed pipe 32.

The use of an inclined drum with a varying angle of inclination makes it easier to unload the processed material and evenly distribute it on the surface of the drum, and moving the UV radiation source over the irradiated material allows you to set various processing modes and thereby increase its efficiency.

The unit is designed for ultraviolet irradiation of animal feed and can be easily implemented in agriculture.
