Description

Description of the invention

A useful model refers to the field of agriculture, intended for cleaning dispersed loose 2 materials from ferromagnetic impurities, for example crushed grain or flour, used in the food industry.

The known device contains a case with covers, an electromagnetic system and a block of concentrators (A.E. USSR

Mo1018717, IPKZ VO4S5/12, VOZS1/00, 1983.

The disadvantage of this device is that as a result of the occurrence of "magnetic shunts" from trapped impurities, which close the turns of the spirals, the quality of cleaning of dispersed loose materials will decrease.

The closest technical solution, chosen as a prototype, is an electromagnetic filter-separator, which contains a cylindrical body with inlet and outlet nozzles, outside of which there is a winding and a ferromagnetic frame equipped with flanges with holes, and inside ferromagnetic nozzles made in the form of spirals of magnetic material (Pat. Mo10518 Ukraine, MPK7 VOZS1/02, 2005.1. 19 However, this device does not allow automating the process of cleaning dispersed loose materials from ferromagnetic impurities due to the lack of control over the periodicity of regeneration.

The basis of a useful model is the task of improving the electromagnetic filter-separator, in which, due to the modernization of the design, namely the installation of a Hall sensor, it becomes possible to record the change in the magnetic field of an external source during the entire period of operation of the filter-separator and to send a signal for the regeneration of the surfaces of the spirals that are caught, which allows to increase the degree of purification of dispersed loose materials from impurities.

The task is solved due to the fact that the proposed electromagnetic filter-separator contains a cylindrical body with inlet and outlet nozzles, outside of which there is a winding and a ferromagnetic frame equipped with flanges with holes, and inside ferromagnetic nozzles made in the form of spirals of magnetic material according to a useful model c) a Hall sensor is installed between the upper flange and the ferromagnetic nozzles, which is located in the horizontal plane at an equal distance between them.

Thus, the use of an electromagnetic filter-separator of this design will allow to increase the degree of purification of dispersed loose materials from ferromagnetic impurities due to the timely regeneration of the surfaces that are caught. The Hall sensor detects the increase in the magnetic field due to the formation of "magnetic Z shunts" between the coils, giving a signal to turn off and clean the separator from accumulated impurities.

Fig. 3 shows the view of Fig. 1. "AND

The electromagnetic filter-separator consists of a non-magnetic cylindrical body 1, with fixed inlet 2 and outlet Z nozzles. Outside the housing 1 there is a winding 4, a ferromagnetic frame 5 with coils 6 and 7, and inside the housing 1 there are ferromagnetic nozzles 8, made in the form of spirals of ferromagnetic material. Holes 9 are made in flanges 6 and 7. Hall sensor 10 is located between flange 6 and ferromagnetic nozzles 8 in such a way that it is located between holes 9 in a horizontal plane. The Hall sensor 10 is connected to the signal amplification unit 11 and signaling unit 12. With 50, the device works as follows. Highly dispersed material contaminated with ferromagnetic impurities enters through the inlet pipe 2 and the holes 9 of the flange 6 into the "working" volume of the filter separator. When turned on

A magnetic field is created from the winding 4 at a constant voltage, the lines of force of which are closed between the ferromagnetic nozzles 8 in the longitudinal direction of the filter separator, under the action of ponderomotive forces of which each ferromagnetic particle, being in the "capture zone" of the filter - separator, will be attracted to the surfaces of the ferromagnetic nozzles 8 . Purified highly dispersed material through the holes 9 in the flange 7 and the outlet pipe o Z enters other technological operations. The holes 9 in the flange 6 are located in such a way that the flow of the dispersed material "" flows directly to the nozzles 8, which makes it possible to distribute it evenly throughout by the volume of the filter separator. When "magnetic shunts" are formed from the accumulated impurities, the field strength in the "trapping zone" increases, which is recorded by the Hall sensor 10. The signal is amplified by the signal amplification unit 11 and (Te) 20 is transmitted to the signaling unit 12, which serves a signal to remove trapped ferromagnetic particles,

And" carried out by turning off the current in winding 4 at a complete stop of the technological line.
