Abstract

The invention relates to devices for sorting chopped wood into fractions using air streams and can be used for sorting chips, sawdust and other loose materials, as well as for separating the conditioned fraction of chips from the waste of sorting process chips in the forest and woodworking industry. The purpose of the invention is to improve the quality of sorting. A device for the aerodynamic sorting of shredded wood includes a sorting chamber 1 with a device for purification of material 2 arranged along adjacent paths of material flow, made in the form of adjacent sections. Each section 3 consists of a visor 4 and an adjacent slotted channel 5 and a sump 6 with a hinged valve 7. Each visor 4 is installed perpendicular to the adjacent wall 8 of the sections 3 above the adjacent wall 9 of the slotted channel 5 and the sump 6 with the possibility of partial overlap of the latter. At the bottom of chamber 1 along its length there are channels 10 with splitters 11. At the top of chamber 1, a suction box 12 with exhaust pipe 13 is installed. In the end wall 14 of chamber 1 an accelerating rotor 15 is located.

Description

The invention relates to devices for sorting chopped wood into fractions using air streams and can be used for sorting chips, sawdust and other loose materials, as well as for separating the conditioned fraction of chips from the waste of sorting process chips in the forest and woodworking industry.

The purpose of the invention is to increase the quality of sorting.

The drawing shows a device for the aerodynamic sorting of shredded wood.

i.e., a 1 stage separation of the chopped wood occurs, the fine fraction being moved to the upper part of the sorting chamber 1 and further to the suction box 12, and the large fraction 5 falls through the channels 10 to the coarse fraction receivers.

The small fraction in the suction box 12 is subjected to the 2nd sorting stage.

With the passage of the wood particles of the slotted channels 5, due to a sharp change in the direction of movement due to interaction with the visors 4, larger particles, having lost speed, fall into sludge

The device includes a chamber 1 of the sorting device 6. As the settling basins are filled 6, with large valves hinged to the valves 7 located along the trajectory

the fraction is periodically discharged into the sorting chamber 1 and then through the channels 10 to the coarse fraction receivers, i.e., an additional selection of large particles takes place

Invention Formula A device for aerodynamic sorting of shredded wood, comprising a sorting chamber with a device for purification of material located in the form of adjacent sections, along channels with dividers, located along the flow path of the material, the flow of material by means of a device 2 for the purification of material, made in the form of adjacent sections 3, each of which consists of visor 4 and adjacent installed teeth from the fines stream. left channel 5 and sump 6 with a hinged valve 7. Each visor 4 is installed perpendicular to the adjacent wall 8 of sections 3 above the adjacent wall 9 of the slotted channel 5 and sump 6 with the possibility of partial overlap of the latter. At the bottom of the chamber 1 along its length there are channels 10 with splitters 11. At the top of chamber 1 there is a suction box 12 with an exhaust pipe 13. In the end wall 14 of chamber 1, an accelerating rotor 15 is located at the bottom of the sorting chamber. its length, the suction box with the unit operates as follows. The fitting branch pipe, installed in the top shredded wood, is intended for the part of the sorting chamber, and different for sorting, goes into the mouth-rotor located in the end face. In addition, the sorter chamber wall is differently inserted into the sorting chamber 1 in 35 with the help of a booster rotor 15 in order to improve the quality of the sort of free flow, inertial movement, each section consists of a suspended airborne aerosol, adjacent mounted slotted 1 canal and a settling tank with hinged klasorting, which is defined by the length and width of the chamber, each visor is installed. Moving in chamber 1, the inert current perpendicular to the adjacent wall is intensively processed by upward of 40 tions over the adjacent wall of the slot channel of 10 channels with air streams Raslo-and sump with the possibility of partial ziem it into small and large fractions, blocking the latter. i.e., a 1 stage separation of the chopped wood occurs, with the fine fraction being moved to the upper part of the sorting chamber 1 and then to the suction box 12, and the large fraction drops through the channels 10 to the coarse fraction receivers. The small fraction in the suction box 12 is subjected to the 2nd sorting stage. With the passage of the wood particles of the slotted channels 5 due to an abrupt change in the direction of movement due to interaction with the visors 4, larger particles, having lost speed, fall into the sedimentation tanks 6. As the sedimentation tanks 6 are filled with rotation of the hinged valves 7 Invention Formula A device for aerodynamic sorting of shredded wood, comprising a sorting chamber with a device for purification of material located in the form of adjacent sections, along channels with dividers, located along the flow path of the material, particles from the fines stream. located at the bottom of the sorting chamber according to its length, the suction box with you
