SU317590A1 - PNEUMATIC HEADER FOR AIR TRANSPORTATION SYSTEMS - Google Patents

Description

The invention may find application in the building materials industry, the chemical industry and in other sectors of the national economy.

On oh, mainly auth. St. No. 252179 is known for a pneumobar: a bath feeder for aerotransiort systems, including a housing with a radial vanes cell drum, one or several drum cells being closed, using lamellar jumpers installed between adjacent radial vanes in their upper part.

Depending on the specific weight of the material supplied to the aeronautical system, the radial blades of the proposed feeder are made with guides in which 1 plate lintels are installed, and on the end wall of the body there is a hatch for changing the plate lintels.

FIG. -1 depicts the proposed pneumatic drum feeder, cross section; in fig. 2 - section along the AA on the fit. one.

The pneumatic reel feeder to the aerotransport systems includes a housing / inside which there is a cell drum 2 with radial pastes 3 on which there are guides 4 for installing replaceable plate bridges 5 in them. Replaceable bridges 5 are fixed from longitudinal movement by pivoting stops 6. At the end wall 7 of the housing / mounted hatch 8 with a quick-release cover 9 connected to the wall 7 by means of a hinge W. The lid 9 is attached to

wall 7

With the help of, for example, hinge nuts 11.

Pneumatic drum feeder works as follows.

First, adjust the feeder to the desired mode pulsating feed by installing 1 Jumper 5 in certain cells. To do this, open the lid 9 of the lid 8 and rotate the drum 2 until the cell needs to be opposite the hatch 8. Then, a jumper 5 is inserted into the guides 4 on the radial blades x 3 and fixed by the Pivoting stop 6. In the same way, the jumpers 5 are placed on other cells and get the drum 2 with the necessary overlapping cells. After adjusting the feeder, the drive (on the che) is not shown shown; rotation of the drum 2 and the powdered MaTepnavT (shown by the arrow) are fed to the feeder. The material enters the open cell of the drum 2 and the three turns of the latter are transferred to the aerotransport system. Due to the fact that open cells alternate with closed ones, a pulsating supply of material into the system with a certain rhythm, which is laid down during adjustment, occurs.

Changing to a different pulsation rhythm happens in the same way as described above.

; Subject of the invention

Pnevmob.rabanny feeder to the aerotransport systems; by bus. St. No. 252179, characterized in that, in order to ensure the possibility of changing the pulsating mode depending on the specific gravity of the material supplied to the aerotransport system, the radial blades in the upper part are made with guides, in which the lamellar blades are mounted, and mounted on the end wall of the body hatch for changing plate jumpers.
