SU1334063A2 - Loose material sampler - Google Patents

Abstract

The invention relates to the quality control of bulk materials and can be used to take samples of grain and other bulk materials from vehicle bodies. The purpose of the invention is to increase the representativeness of the samples taken by eliminating the material being sucked from the surface of the embankment. The goal is achieved by the fact that the sampler, which contains two concentrically arranged pipes with openings, each of which is equipped with a vibration drive, is provided in its initial position below the open end of the internal pipe with an elastic diaphragm attached to it and a cylindrical glass freely covering the lower part of the external pipe, suspended on cables to an external pipe, 3 Il. co stock co 4 Oh: co 14)

Description

one

The invention relates to a technique for controlling the quality of loose materials and can be used for sampling, in particular for sampling, grain and other bulk products from the bodies of motor vehicles in order to determine their physical and biochemical characteristics.

The purpose of the invention is to increase the representativeness of the sample being taken by eliminating the material being sucked from the surface of the embankment.

The device consists of two concentrically located inner D and outer 2 pipes. The inner tube 1 is connected to the vacuum pneumatic system and has two rows of holes at the lower end - the upper 3 and lower 4, the upper end of the inner tube 1 is fixed to the frame 5 with vibration actuator 6, the outer tube 2 in the lower part is equipped with a truncated cone 7, and in the upper part it has windows 8, the upper end of the pipe 2 is fixed on the frame 9 with the vibration actuator 10, inside the outer pipe

In the assembled free state, the inner 1 and outer 2 pipes are oriented so that the frame 5 of the inner pipe 1 is supported on the frame 9 of the outer pipe 2 , the upper row of 3 holes of the inner tube 1 is below the overlapping sleeve 11, and the lower row of 4 holes of the inner tube is below the truncated cone 7 of the outer tube 2, In addition to TOfo, the upper part of the cylindrical cup 15 is above the lower end of the outer tube 2, and movable

As the device is immersed, a layer-by-layer selection of the material is transported to the unloading. The presence of material in the middle of the upper row of windows opens the inner tube preventing material and contributes to proportional selection of the entire embankment height.

The device works as follows

By means of a lifting and lowering mechanism, the device is lowered into the bulk material embankment. Before entering the bulk, the pneumatic system and the vibrating actuator 6 of the inner tube 1 are turned on. At the moment the device enters the bulk material embankment, the flexible movable diaphragm 14 lies on the surface of the embankment, and the cylindrical cup 15 begins to move along the external tube 2. bulk material embankment, increases the length of air filtration sections in the grain layer and its resistance, which leads to a decrease in air filtration rates in the pores of the bulk material and prevents Op material from the surface of the embankment with the area exceeding the diameter of the inner tube.

As the device advances into the material, it fluidizes under the action of vibration through the open end of the inner tube 1 into the inner cavity of the tube 1 and reaches its upper row of 3 holes, the air passing through the openings 8 of the outer tube 2 passes through fixed blades 12, twists and, passing through 35 d through the upper row of 3 holes

The inner tube 1 captures the material - and transports it to the discharger. Fixed blades improve the organization of the supply of air in the inside of them30

As the device sinks, material is layer-by-layer taken out and transported to the unloader. The presence of material between the upper row of windows and the open end of the inner tube prevents material from leaking and promotes layer-by-layer proportional sampling over the entire embankment height.

When the inner tube reaches the bottom, we turn off its vibration drive 6 and turn on the vibrator 10 of the outer tube 2. At the same time, the inner tube remains stationary, and the outer tube 2, moving along the inner tube 1, lowers to the bottom. At the same time, the upper row of 3 holes overlaps the overlapping sleeve I1 and the lower row of 4 holes is displaced inside the truncated cone 7 of the outer tube 2. This causes a redistribution of air, which, passing through the lower row of 4 holes, transports the rest of the material to the discharger.
