Description

The invention relates to the food industry and can be used in enterprises of the canning industry.

A device for separating seeds is known (AS USSR No. 1738235, class A23N 4/12, 1992), comprising a cylindrical body provided with a helical guide, rotatably mounted and mounted therein with a hollow perforated rotor, a water supply unit, loading and unloading fixtures.

The disadvantage of this installation is the limited technological capabilities and the lack of efficiency of the separation of seeds.

Closest to the proposed invention is a device for isolating seeds (RF patent No. 2467668, class A23N 4 / 12.1, publ. 11/27/2012, bull. 23), containing a cylindrical body provided with a screw guide, mounted for rotation and installed in a hollow perforated rotor, a water supply unit, loading and unloading devices.

The disadvantage of this installation is the limited technological capabilities and the lack of efficiency of separation of seeds and large dimensions in length.

The technical solution is the expansion of technological capabilities, increasing the efficiency of seed allocation, reducing the size of the length.

The technical solution is achieved by the fact that in the vibrating device for separating seeds, comprising a housing and a hollow perforated rotor installed in it, a water supply unit, loading and unloading devices, the housing is made in the form of a box closed on all sides with torso located one under the other and rigidly connected in a single technological chain, screw hollow perforated rotors, vibration exciter and elastic elements, while screw hollow perforated rotors are installed alternately for one another and made in the form of a multi-helical perforated screw surface with perimeter helical lines and helical grooves inside the rotor at an angle of 5 ° -45 ° to the axis of rotation of the rotor in the form of wave-shaped pockets with the centers of curvature of the pockets of a curved shape of a screw perforated surface located inside and outside the rotor’s cross section, they are mounted from one rolled into cylindrical coils connected to each other along the longitudinal edges of a perforated strip of the same width, bent in size Bend lines bent at an angle to its longitudinal edges with the formation on the outer and inner perforated surfaces directed to one side at an angle of 5 ° -45 ° to the axis of rotation of the rotor of the screw lines and screw perforated surfaces in the form of pockets of a wavy shape, which around the perimeter of the rotor can be different not only in shape but also in size, and the water supply unit includes three collectors and six nozzles mounted inside the housing above each rotor, two of which are inserted through the walls of the housing into each of rotor neck, and unloading devices are made in the form of slides mounted inside the housing at an angle to the horizontal and with perforations in the sections of the slides located inside the housing, and the direction of the helical lines of each of the belly below-installed helical hollow rotors is opposite to the direction of helical lines of the helical hollow rotor mounted above.

According to the patent literature not found a technical solution similar to the claimed, which allows to judge the inventive step of the proposed vibration device for seed separation.

The novelty is due to the fact that thanks to the internal spiral perforated surfaces of a wave-like shape around the perimeter of the rotor, crushed melons from loading to unloading are not only provided with the horizontal arrangement of the rotor, but technological capabilities are also expanded.

The novelty also lies in the fact that the perforated surface of the rotor is made of one or more perforated strips, which expands technological capabilities and simplifies manufacturing.

The novelty of the proposal is also due to the fact that the perforated rotor surface is made around the perimeter in the form of a multi-helical perforated screw surface with helical grooves inside and outside at an angle of 5 ° -45 °, which reduces energy costs for moving crushed melons from loading to unloading, expanding technological capabilities .

The novelty is that due to the fact that the perforated surface of the rotor is made around the perimeter in the form of a multiple-helical surface with screw grooves inside and outside at an angle of 5 ° -45 ° to the longitudinal axis of the rotor in the form of pockets of a wave-like shape with the centers of curvature of the pockets of a curved shape of a screw perforated surfaces located inside and outside the cross-section of the rotor, the energy intensity of collisions of crushed melons increases, technological capabilities expand.

The novelty is due to the fact that the rotor is equipped with helical grooves inside and outside at an angle to its axis in the form of pockets of a wave-like shape with centers of curvature located inside and outside the cross section of the rotor, which ensures that the particles of crushed fruits of the melon melon have a complex spatial movement, which violates the stationary nature of their movement, It provides self-cleaning of the screening surface of the rotor, reduces the size of the vibratory device for the selection of seeds along the length, expands the technological capabilities.

The novelty lies in the fact that with the same rotor diameters of the known design and the proposed rotor design due to the presence of pockets of a wave-like shape, the particles of crushed melons rise significantly above the angle of repose, which expands the technological capabilities and increases the yield of seeds.

The novelty lies in the fact that due to the curved internal screw perforated surfaces of the rotor, the vectors of the particle velocity of crushed melons of melons are changed during transportation from loading to unloading, which contributes to the intensification of the process of seed selection and extends technological capabilities.

The novelty is seen in the fact that the rotor is made of one perforated strip, which simplifies manufacturing and expands technological capabilities.

The novelty of the proposal also lies in the fact that inside the screw rotor with a complex internal perforated surface in the form of a combination of two curved surfaces at each point there are multidirectional components of the movement, which intensifies not only the processes of seed selection, but also expands the technological capabilities.

The novelty also lies in the fact that with the same rotor diameter of the known design and the proposed machine design, in the proposed design, the scan length of the rotor diameter around the perimeter due to the perimeter of the rotor along the perimeter is much larger, therefore the path of the passage of particles of destroyed melons is compared with known constructions of the rotor is much larger, which makes it possible to reduce the dimensions of the rotor of a vibrating device for separating seeds, both in length and in diameter.

The novelty of the proposal also lies in the fact that around the entire perimeter of the perforated screening surface of the rotor, the passage section varies not only in shape but also in area, which provides alternate compression and expansion of the flow of crushed melon particles in each section of the perforated surface, its self-cleaning, and, therefore, increasing productivity, efficiency, reducing size and expanding technological capabilities.

The novelty of the invention lies in the fact that when the vibration exciter is working, crushed melon particles that circulate inside the belt mounted one below the other, rigidly fixed in the vibrating housing of the perforated rotors in planes perpendicular to their horizontal axes, receive additional movement from the internal perforated surfaces of a wavy shape, which intensifies the selection of seeds from crushed melons, increases productivity, expands the technical possibilities spine and reduces the dimensions of length.

The novelty also lies in the fact that under the influence of the perturbing forces of the vibrator through the box walls, crushed melon particles rotate in planes perpendicular to the axis of symmetry of the rotors, while their screw perforated surfaces change and give additional movement to the crushed melon fruit particles, provide an increase in the yield of seeds as well as move them from loading to outlet openings.

The novelty of the invention lies in the fact that, since the frequency of movement of the crushed melon particles in the proposed design is determined not only by the frequency of vibrations created by the vibrator, but also by the number of undulating surfaces around the perimeter of the rotors, such a structural design increases the frequency of collisions of crushed melon particles among themselves and with perforated walls of the rotors, it increases the productivity of seed extraction, increases technological capabilities.

The novelty of the invention lies in the fact that such a structural design of the rotors allows for a consistent gradual compaction and discharge of the flows of crushed melon particles as they move from loading to unloading, as well as to increase the efficiency of seed extraction and expand technological capabilities.

The novelty is also seen in the fact that the area and shape of the transverse and longitudinal sections of the rotors change over the entire length many times from loading to unloading, which changes the speed and trajectory of the movement of crushed melon and pumpkin particles, and expands technological capabilities.

The novelty is that due to the curved internal screw perforated surfaces of the rotors, the vectors of the speed of the particles of crushed melons and gourds change during transportation from load to unload, which contributes to the intensification of the process of seed selection, and expands technological capabilities.

The vibrating device for isolating seeds (Fig. 1, Fig. 2, Fig. 3) consists of means for loading 1, means for unloading seeds 2, 3, 4 and withdrawing them outside the vibrating device for separating seeds, means for unloading fibers and water 5 and withdrawing them outside the vibrating device for isolating seeds, means for unloading the destroyed fruit 6 and removing them outside the vibrating device for isolating seeds, box 7, installed using elastic elements 8 on the base 9. A vibration exciter is mounted in the lower part of the box 7 one 0. The vibrating device for isolating seeds is equipped with containers 11, 12, 13 for receiving seeds after isolation from melons and pumpkins, and is also equipped with a capacity 14 for receiving fibers and water and a capacity 15 for receiving destroyed fruits. In the box 7, made closed on all sides, the upper perforated rotor 16, the middle perforated rotor 17, the lower perforated rotor 18 are mounted under each other and connected in a single technological chain. To ensure transportation from loading to unloading the fruits of melons and pumpkins, each of the rotors 16 , 17, 18 can be mounted in the box 7 with a slope of 2 ° -5 ° to the discharge side. When the vibrating device for separating seeds is operating, continuous movement of crushed melons and pumpkin fruits from loading to unloading is provided.

The nozzle of the loading device 1 is mounted in the inlet of the upper perforated rotor 16. The outlet 19 of the upper perforated rotor 16 is closed by a lid 20, which simultaneously covers the inlet 21 of the middle perforated rotor 17 and allows the particles of crushed melons and pumpkins to move from the upper perforated rotor 16 to underlying middle perforated rotor 17YU, namely from the outlet 19 of the upper perforated rotor 16 into the inlet 21 of the underlying middle p of the perforated rotor 17. The outlet 22 of the middle perforated rotor 17 is closed by a cover 23, which simultaneously covers the inlet 24 of the underlying third screw rotor 18, ensuring the transfer of crushed melons and pumpkins from the second middle rotor 17 to the lower perforated rotor 18. Under the outlet 25 of the third perforated rotor 18, an unloading device 6 is mounted for withdrawing outside the vibrating device for separating the seeds of the destroyed fruit into the container 15. For receiving seeds and output and them outside the vibrating device for separating seeds under the first perforated rotor 16 mounted means for unloading 2, under the second perforated rotor 17 mounted means for unloading 3, under the third perforated rotor 18 mounted means for unloading 4. Cell sizes of perforations of rotors 16, 17, 18 is larger than the maximum size of the fruit seeds, and the cell size of the perforated part of the means for unloading 2, 3, 4, fixed under the fragility to the horizontal to the walls of the box 7 is smaller than the minimum size of the fruit seeds. Therefore, when the means for unloading 2, 3, 4 get into the perforated sections under the influence of vibration and tilt, the seeds are removed outside the vibrating device for separating seeds in the containers 11, 12, 13, and the fibers and water flow down and through the means for unloading the fibers and water 5 are taken out of the scope of the vibratory device for isolating seeds in a container 14 for receiving fibers and water. Means for unloading 2, 3, 4 are made in the form of slides at an angle to the horizon, and the sections of these slides 2, 3, 4 inside the box 7 are perforated, and solid outside the case 7. For output outside the device vibrating for the separation of seeds of destroyed fruits mounted unloading device 6, which transports them to the tank 15.

The vibrating device for isolating seeds is equipped with a water supply unit, including three collectors 26, 27, 28 above each rotor 16, 17, 18 and six nozzles 29, 30, 31, 32, 33, 34.

The perforated rotor 16 (Fig. 4, Fig. 5) is made around the perimeter in the form of a multi-screw perforated surface with helical lines along the perimeter and helical grooves inside the perforated rotor 16 in the form of pockets of a curved shape at an angle of 5 ° -45 ° to the axis of rotation of the rotor 16 with the centers of curvature of the pockets of a wave-shaped screw perforated surface located inside and outside the cross section of the perforated rotor 16. The perforated rotor 16 (Fig. 4, Fig. 5) is made of at least one perforated mats 35 connected along the longitudinal edges 36 (shown in FIG. 4 by a dash-dot line) by known methods, for example, by welding, with the formation of curvilinear shapes along the outer and inner surfaces of helical lines and helical surfaces (FIG. 5) in the form of pockets of the inner surface of a wavy shape 37 , 38, 39, 40, 41, 42 and pockets along the outer surface of the wave-like shape 43, 44, 45, 46, 47, 48.

The perforated strip 35 (Fig. 6, Fig. 7) is bent along straight lines 49 at equal angles β to the edges 36 of the perforated strip 35, spaced from each other at distances equal to the scan length of the perimeter of the wave-like pockets, for example, at distances L ₂ .

The perforated strip 35 after bending (Fig. 7) is rolled into cylindrical coils (Fig. 8), connected to each other along the longitudinal edges 36 by known methods, for example by welding, into a perforated rotor 16.

Perforated rotors 17 and 18 are made in a similar way, i.e. as well as perforated rotor 16.

The direction of the helical lines of each half below the installed helical hollow rotor is opposite to the direction of the helical lines of the helical hollow rotor mounted above. For example, the direction of the helical lines of the rotor 17 is opposite to the direction of the helical lines of the rotor 16, and the direction of the helical lines of the rotor 18 is opposite to the direction of the helical lines of the rotor 17 (Fig. 1). Therefore, during the operation of the vibrating device for separating seeds, the crushed melons of melons are continuously moved from loading to unloading.

A vibratory device for seed isolation works as follows.

By means of a loading device 1, crushed melons and gourds are continuously loaded into the upper rotor 16 and, through three collectors and six nozzles, water flows are continuously fed into the rotors and the housing 7. Under the influence of disturbing forces, the perforated rotors 16, 17, 18 of the crushed melons and water flows transmit disturbing forces. Particles of crushed melons and water flows under the influence of these disturbing forces under the influence of vibration rotate in planes perpendicular to the axis of symmetry of the rotors 16, 17, 18. The perforated spiral walls of the wave-like shape of rotors 16, 17, 18 change and give additional movements to the particles of crushed melons and water flows and provide an increase in the productivity of the selection of seeds from them, and also move particles of crushed melon and water flows from the load to the outlet, for example to the outlet Tia 19 of the rotor 16. As the advancement of crushed particles melons and water flows along a horizontal axis of the rotor 16 is released and seeds they rotor through holes 16 in the output means for discharging 2 and further beyond the unit for allocation of seeds. Under the influence of vibration and with the help of the cover 20, crushed melon particles and water flows are loaded through the opening 21 into the underlying rotor 17, along the perimeter of which there are helical lines, the direction of which is opposite to the direction of the helical lines of the upper rotor 16. With their help and under the influence of vibration, the seeds through the holes the rotors 17 are displayed in the means for unloading 3 and then beyond the limits of the vibrating device for separating seeds, and the remaining particles of crushed melons are moved to the outlet 22 and by cr the pulleys 23 are moved through the inlet 24 into the inner cavity of the rotor 18. Under the influence of vibration of the screw perforated walls of a wave-like shape and helical lines around the perimeter of the rotor 18, the seeds are discharged into the means for unloading 4 and then outside the vibrating device for separating seeds, and the destroyed fruits and streams water moves along the horizontal axis and through the hole 25 and with the help of the unloading device 6 are discharged outside the vibrating device for the separation of seeds.

The technical and economic advantages of the invention arise due to the superposition of crushed fruits from vibration in planes perpendicular to the horizontal axis of the perforated rotors due to the additional movement of the perforated rotors imparted by the walls to the wave-like shape, which facilitates the passage of seeds through the holes of the perforated rotor walls and expands technological capabilities . In the process of moving the crushed fruits from loading to unloading, their particles make a complex spatial movement, since the direction of their movement under the influence of vibration changes under the influence of the walls of the wave-like shape of the perforated rotors, productivity increases, the process of seed selection is intensified, technological capabilities are expanded.
