Abstract

This invention relates to the pneumatic transportation of bulk materials. The purpose of the invention is to reduce material consumption. The installation includes a pneumatic feeder 1, a transport pipeline 4, a cyclone 5, a pipeline 7 for exhaust gas discharge and an exhaust air purification unit 8. The latter is made in the form of a frame 10, on which L-shaped elements 11 are fixed with overlapping of their adjacent horizontal shelves with a vertical gap, forming a slotted platform. Node 8 is located under the discharge opening 6, which communicates the cyclone 5 with the atmosphere. The cavity 9 of the housing of the unit 8, located under the elements 11, communicates with the outlet of the pipeline 7. The feeder 1 through the pipeline 4 bulk material is transported to the cyclone 5, where it is separated from the carrier gas. From cyclone 5, the exhaust gas through pipeline 7 is directed to cavity 9. The material poured out from cyclone 5 forms a filter layer 12 on the platform of L-shaped elements, through which the exhaust gas passes from cavity 9 to the atmosphere, clearing fines that are not captured in cyclone 5. The invention reduces the consumption of materials and the cost of gas cleaning devices. 2 Il.

Description

The exhaust gas passes from the cavity 9 into the atmosphere, clearing the fines that are not captured in the cyclone 5. The invention reduces the consumption of materials and the cost of gas cleaning devices, 2 sludge.

The invention relates to the pneumatic transportation of bulk materials, in particular to installations for pneumatic loading them into pavilion-type warehouses, and can be used in agriculture, chemical and other industries.

The purpose of the invention is to reduce the installation material consumption.

Figure 1 shows an installation diagram for the pneumatic conveying of bulk materials; Fig.2 node cleaning of exhaust gas, the section.

The installation contains a pneumatic feeder 1, for example a chamber, with a loading valve 2 and an aspiration valve 3, a transport pipeline 4, a cyclone 5 with an adjustable diaphragm 6 in the discharge port, communicating with the atmosphere, a pipeline 7 for discharge of exhaust gas from the cyclone 5 and an exhaust gas cleaning unit 8 placed on the base (for example, on the ground) under the discharge opening 6 of the cyclone 5. The cavity 9 under the L-shaped elements of the body of the flue gas cleaning assembly 8 is connected to the outlet of the pipeline 7. The housing of the cleaning assembly is about The produced gas is formed by the frame 10 with L-shaped elements 11 fixed on it, installed with mutual overlapping with a vertical gap of their adjacent horizontal shelves. The horizontal shelves of the elements 11 form a slotted platform for forming on it a filtering layer 12 of bulk material coming from the discharge opening 6 of the cyclone 5.

The installation works as follows

Pneumatic feeder 1 is filled with bulk material, which is then transported in a stream of compressed gas through pipeline 4. In cyclone 5, the material is separated from the carrier gas. The material separated from the gas from the cyclone 5 through the discharge opening of the diaphragm 6 is poured onto the platform formed by the horizontal shelves of the L-shaped elements 11. The discharge intensity is regulated by changing the orifice plate 6. The area forming the L-shaped elements 11 forms filter layer 12. The spent dusty gas from the cyclone 5 through the pipeline 7 enters the cavity 9 of the waste cleaning unit, gas. Spent dusty gas from the cavity 9 through the vertical gaps of the horizontal shelves of the elements 11 passes into
