Description

one

The invention relates to roller planters and can be used in woodworking, furniture and other g industries, where cyclones are used to separate transported materials or industrial wastes and air.

Cyclones are known which consist of fQ of a cylindrical-conical body with a spiral upper lid, on which the inlet nozzle is tangential, a cylinder BHytpeHHelio with louvers, acting as an inertial dust separator; ij.

A week of this type of cyclone is that a significant amount of transported material or production waste is emitted into the atmosphere through exhaust pipe-20 bu together with air, which leads to irretrievable loss of m / and to contamination of 25 areas around the cyclone.

Also known is a cyclone with an expander, containing a cylindrical-conical body with a tangential inlet nozzle AND an axial bore for

The dust supply is located concentrically in the body of the cylinder, the expander placed above it with the c. He was ardent team. conical; funnel and exhaust pipe 2}.

A characteristic feature of this type of cyclone is the presence of a special expander, which serves to reduce the speed in front of the exhaust pipe.

The disadvantage of the prototype is that materials or production waste accumulated in the conical funnel of the expander must periodically be removed manually, which is practically very difficult to implement, since the exhaust pipe of the cyclone is located, as a rule, at a height of about 10 m above ground level. This causes the funnel to overflow, around it, in the expander, the transport speed is restored again and again through the exhaust pipe, particles of material or production waste are again thrown out with the air.

The aim of the invention is to improve air purification and the removal of materials or industrial waste precipitated in the conical funnel of the expander, as well as the possibility of controlling the amount and speed of air in the pipe.

The goals are achieved by the fact that the cyclone is provided with an axial tube, one end of which is connected to the funnel and the other end is located in the conical part of the body above the hole for dust removal.

The installation location of the lower edge of this pipe is selected as follows. ;

Velocity in the pipe is set; lot: the ra must be several times greater than the velocity in the upper exhaust pipe of the cyclone. There is a place in the cyclone cone, where the speed, {in the area of the field, minus the area of the pipe) corresponds to the desired speed in the pipe. This location is optimal for installing the lower edge of the pipe. In order to provide the same possibility of setting and adjusting the speed in the pipe, at its lower end the telescopic pipe is mounted with the possibility of vertical movement.

The drawing shows a General view of the cyclone in the section. . .

The cyclone consists of a shell; 1 ,, the upper part of which has a cylinder, an inlet 2, a cone 3 .; with a hole 4 dl. the internal cylinder 5, the expander 6j of the exhaust pipe 7, the conical funnel 8, the axial pipe 9 and the telescopic pipe 10.

. Cycling as follows

Air, together with the transported material or production waste, through the inlet 2

Falls into the upper part of housing 1, where due to centrifugal forces heavy particles of material or waste

 productions are pressed against the walls. and further along the walls of the cone 3, posturiasJt to the opening 4. The air, together with a certain amount of suspended particles, passes through the inner cylinder 5 into the expander 6. The air velocity in the expander decreases and. suspended particles fall into a conic recess 8, from which a pipe 9 and a nozzle 10 Trans-6 to 51 aperture 4. If necessary, change

the speed, and therefore the amount of air passing through the pipe 9, the pipe 10 is moved into the top or down.

The application of the proposed design of the cyclone makes it possible to fully automate the removal of suspended particles of the transported material or production wastes deposited in the cone funnel with the help of the same

U of the transport fan and due to this, firstly, to eliminate the clogging of the area around the cyclone, and secondly, if the material is transported, then by eliminating its emission into the atmosphere, to obtain corresponding.

.5 savings. In addition, by moving the telescopic nozzle up and down it is possible to adjust the speed and

. the amount of air passing through

0 pipe.
