(54) DEVICE FOR CONTINUOUS MEASUREMENT

MASS OF MATERIAL IN TRANSPORT CAPACITIES

The invention relates to the field of weighing technology.

Devices are known for continuously measuring the mass of incoming or consumable material, containing force sensors and recording equipment l

The closest in technical essence is a device for continuous measurement of the consumed mass, containing load sensors connected to a lifting unit, and a bellows compensator-sealer (h.

The known device does not provide for weighing transport containers with the required accuracy.

The purpose of the invention is to improve the accuracy and reliability of the device for continuous measurement of the mass of materials in transport containers, hermetically joined to the loading apparatus.

This goal is achieved by the fact that the pressure compensator is pressed against the tank with springs mounted between its flanges and rigidly connected to the top.

one of them, and a limit switch mounted on the upper flange and interacting with a lever fixed on the bottom flange, and the contacts of the limit switch are inserted into the activation circuit of the drive of the load-lifting unit.

The drawing schematically shows the described device.

The device contains a force-measuring strain gauge 1, mounted in the lifting unit 2 transport capacity E,

A pressure compensator, made in the form of a bellows 6 with the upper 7 and lower inlets and springs 9 made of a corrosion-resistant material and providing additional communication between the flanges, is pressed against the discharge pipe 4 of the technological apparatus 5. The springs are pressed to the flange by 8 nuts 10 and centered by rods 11 with nuts 12.

The lower flange 8 communicates with compensator .3 transport capacity through the gasket 13. The upper flange 7 kimpgg15satora npfiKpeji / KM -r smechtgy vyklyuchptel 14, Mi-MonfficvnyioiuHfi SH with tol Catel 1-5, the lower ustanovleiilm flalde 8. The apparatus works follows-puyuschpm okay The springs 9 are clamped with nuts 12, creating a preliminary force on the flange 8, sufficient to seal the junction of the connecting tank 3 and the compensator. With the help of the node 2, the capacity 3 is attached through the gasket 13 to the lower flange 8 of the compensator. Compressing the gasket occurs as long as the magnitude of the forces arising in it does not exceed the resistance of the springs 9. When such efforts are reached, the pusher 13, mixed together with the flange S Hybrid, influences the upper contact of the switch 14, which gives the unit 2 to disconnect the load drive of the unit 2. When the transport container 3 is filled with the product under the effect of increasing load, the compressive forces acting in the joint unit of the container 3 and the apparatus 5 decrease, and the lower flight 8 of the compensator moves downwards. At the same time, the rammer 15 acts on the lower contact of the switch 14, which gives a signal for switching on the load of the cargo terminal 2. Lifting;) ipaHciiopTiuxu of the tank 3 is carried out until the operation of the upper contact is connected) Switch 1 The load cells 1 mounted in the node 2 are sensed by the sensor, which will be applied. the weight of the transport container 3 and the product, as well as the resistance forces resulting from pressing of the transport container 3 to the apparatus 5. Since the displacement of the lower flange 8 occurs within very limited limits and the compression of the springs 9 is changed Consequently, the relative change in load in the junction of the container 3 and the apparatus 5 is also insignificant, and the increase in load due to the change in load is small. Due to the fact that the weight of the actual transport capacity and the volume of the razka in the node of the connection between the vessel and the air inlet are constant, the force perceived by the strain gauges uniquely characterizes the mass of the product entering the transport tank. Apparatus of the Invention A device for continuously intending material in transport containers containing teizodatchiki, mounted in a lifting unit with a drive, and a compensator force pressing the container to the loading apparatus with a material, between the flanges of which is installed an elastic sealing element, characterized in that, in order to improve accuracy and reliability, in which the compensator forces the pressure vessel equipped with springs mounted between the flanges and associated with the upper one, and the limit switch mounted he Khnemu flanpe and cooperating with a lever fixed to the lower Flandin, wherein the contacts limit switch incorporated in the circuit incorporating the lifting assembly.
