Abstract

The invention relates to a pneumatic transport of unit loads on an air cushion. The purpose of the invention is to improve performance. The pneumoconveier includes plates 6 movably mounted along the horizontal upper wall 2 of the pneumatic chamber 1 and walls 2 connected to the protrusions 4 by means of bimetallic plates 5. The plates 5 provide for the deflection of air jets from w, spruce holes 3 from the vertical position at an angle of medium due to the average the position of the plates 6 relative to the openings 3. Depending on the temperature of the supplied air, the inclination of the air jets will automatically change, and consequently, the speed of movement of the product. 1 hp ff, 5 ill.

Description

The invention relates to industrial transport, namely to pneumatic conveyors, and can be used to combine the operations of heat treatment with air in a stable mode and transport piece goods on the air gap.

The aim of the invention is to improve the performance.

FIG. 1 shows a schematic pneumatic conveyor, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 — node I in FIG. 1 with a plate in an intermediate position and a jet deflected at an angle; in fig. 5 - the same, with the plate in the extreme position, and the jet deflected at an angle of max.

The pneumatic conveyor consists of a pneumatic chamber 1, a horizontal upper wall 2 with rectangular slit openings 3 made with protrusions 4 connected

governing 7 in grooves 8 relative to the middle position by the value L.

The air jets are deflected in the direction of displacement. Product speed increases. The angle of inclination of the jets depends on the temperature of the heated compressed air supplied to the pneumatic chamber 1. The higher the temperature of the air supplied to this area, the faster the product moves in this area and vice versa.

Thus, depending on the temperature of the supplied air, the inclination of the air jets automatically changes, and consequently, the speed of movement of the product. This maintains the stable thermal mode of the moving article along the entire length of the conveyor.

Similarly, the thermopneumoconveier operates in cooling mode when cold compressed air is supplied to the pneumocamera. In this case, the inner layer of bimetallium with the help of bimetallic plates 5 in 20 of them is made with a large arc ratio with moving plates 6, with linear expansion.

1. A pneumatic conveyor containing a pneumatic pneumatic convector operates as follows: around the chamber with protruding lateral walls above the horizontal, upper wall, and pneumatic chamber 1 is supplied with heated hedgehog mounted on the upper horizontal air passing through rectangular walls slotted slotted holes 3 in a fixed verstily, plates movable along it for a horizontal plate 2. Arcuate adjustments of the angle of the jets of flow, distinguishing bimetallic plates 5, are external In order to improve, the excks are made with a large coefficient of operational characteristics, upper horizontal expansion linear, so that at a given process temperature they ensure the deflection of air jets from the vertical position by the angle of the average due to the average position of the movable plates 6 relative to the orifice holes 3 between the extreme positions corresponding to zero and maxi 35 maximum jet deflection angle. At an angle The pneumatic chamber 's horizontal wall is made with protrusions between slit openings, while the Pneumatic conveyor is provided with bimetallic plates bent in an arc, each of which is fixed at one end on a ledge located in front of it during the movement of products, and on the plate located between the corresponding said ledge and jet deviation, the medium is maintained with a slot-hole and the speed of movement of the products is established with an excitability. Under the influence of heated air, the temperature of which is higher than the set temperature of the technological mode, the bimetallic arcuate plates 5 change their length and displace the movable plates 6 with the possibility of interacting with the side walls of the pneumatic chamber through guides. 2. A pneumatic conveyor according to claim 1, characterized in that the protrusions and plates are made with vertical side walls. five governing 7 in grooves 8 relative to the middle position by the value L. The air jets are deflected in the direction of displacement. Product speed increases. The angle of inclination of the jets depends on the temperature of the heated compressed air supplied to the pneumatic chamber 1. The higher the temperature of the air supplied to this area, the faster the product moves in this area and vice versa. Thus, depending on the temperature of the supplied air, the inclination of the air jets automatically changes, and consequently, the speed of movement of the product. This maintains the stable thermal mode of the moving article along the entire length of the conveyor. Similarly, the thermopneumoconveier operates in cooling mode when cold compressed air is supplied to the pneumocamera. In this case, the inner bimetallcamera layer with side walls protruding above the horizontal upper wall and mounted on the upper horizontal wall having rectangular slotted openings movably along it plates for adjusting the angle of the stream jets, improve the performance characteristics of the upper horizontal The pneumatic chamber 's horizontal wall is made with protrusions between slit openings, while the Pneumatic conveyor is provided with bimetallic plates bent in an arc, each of which is fixed at one end on a ledge located in front of it during the movement of products, and on the plate located between the corresponding said ledge and possibility of interaction with the side walls of the pneumocamera by means of guides. 2.
