Description

(54) SEPARATOR

one

The invention relates to devices for separating a mixture of powdered materials depending on the particle size and can be applied in chemical technology, heat and power engineering, and the production of building materials.

A separator is known that includes coaxially mounted housings, a radial blade apparatus located on the lid of the outer casing, branch pipes for supplying a material to be divided and for discharging the original product 1.

The disadvantage of the device is low separation efficiency.

The closest to the invention in terms of technical drying and the achieved result is a separator comprising coaxially arranged cylindrical conical bodies with covers, a flow curler installed between the bodies, drafts attached to the covers of the bodies, loading and unloading devices 2.

A disadvantage of the known device is the low quality of separation.

The purpose of the invention is to improve the quality of separation.

This goal is achieved by the fact that a separator comprising coaxially arranged cylinders with lids, a flow curler installed between the bodies, drawers attached to the covers of the bodies, loading and unloading devices, is provided with annular partitions between the covers and fastened on the chains; installed parallel to each other and housing covers.

Moreover, the outer diameter of each annular partition is determined from the ratio

Oy D, xV- where DC. - diameter of the cylindrical part of the outer case; DC, is the diameter of the cylindrical inner body; j (is the diameter of the unloading device, laziness for dust removal; h is the number of ring partitions; i is the number of the partition in the direction from the lid of the inner case to the lid of the outer case. In Fig. 1, the proposed device is a general view; Fig. 2 is a section A - A in Fig. 1. The separator contains an outer casing 1 with a lid 2 and an inner casing 3 mounted coaxially with it with a lid 4, which is attached by means of 5 to the lid 2. The lids 2 and 4 limit the separation zone 6, but divided by parallel to each other and covers 2 .and 4 ring out partitions 7 to equal separation chambers 8. The partitions 7 are fastened on rods 5. For example, using threaded pairs. Between the cylindrical parts of bodies 1 and 3 there is an axial twisting device 9, the blades of which simultaneously rotate around their axes 10. In The lower part of the housing 1 has an inlet 11 for supplying the source material to be separated and a chute 12 for removing the percine separat. An outlet 13 is attached to the upper lid 2 for exhausting gases together with the finished dust, and in the lower part of the inner casing 3 is a chute 14 for secondary waste. The separator works as follows. The material to be separated with the gas flow through the inlet 11 enters the space between the housings 1 and 3, where under the action of gravity and inertia the largest particles are separated and enter the chute 12. Leaving the dust with the gas flow is carried into the spatula, twisted by blades 9 and enters the separation zone 6, where there is a uniform distribution of the gas-dispersed flow through the separation chambers 8. In the separation chambers, under the action of oppositely directed resistance forces and centrifugal force, classification occurs ( eparatsi) particles. Small particles together with the gas are carried to the nozzle 13, and the large ones are partially thrown to the inner wall of the outer case, subjected to repeated separation, and partially fall into the annular gap, forming a lid 4 and the case 3, and then into the chute 14. Use The proposed device allows increasing the separation efficiency from 0.65 to 0.8, reducing the frequency of material circulation through the separator by 20–30% and improving the quality of the finished product (it increases the uniformity of the structure of the finished product from 0.85 to 1.2 ). Claim I: A separator comprising coaxially arranged cylindrical conical bodies with lids, a flow curler installed between the bodies, ties attached to the lids of the bodies, loading and unloading devices, characterized in that, to improve the quality of separation, the separator is provided with spacers between the lids and fixed on the ring with circular partitions. installed parallel to each other and housing covers. 2. A separator according to claim 1, characterized in that the outer diameter of each annular partition is determined from the ratio), and the inner diameter of each annular partition is determined from the ratio Db Dbi D where D is the diameter of the cylindrical part of the outer casing; . DO is the diameter of the cylindrical part of the inner body; outlet Diameter of the discharge device for removal of dust; K is the number of annular bulkheads; i is the partition number in the direction from the lid of the inner case to the lid of the outer case.
