Description

Technical Field

[0001] The present invention relates to the technical field of density detection, and specifically to an attapulgite density detection device. Background Technique

[0002] Attapulgite clay, also known as palygorskite or palygorskite, is a water-rich magnesium silicate clay mineral with a chain-layered structure. Attapulgite is a crystalline hydrated magnesium aluminum silicate mineral with a unique layer-chain structure. There is lattice substitution in its structure, so the crystal contains an indefinite amount of Na+, Ca2+, Fe3+, Al3+. The crystal is needle-shaped, fibrous or fibrous aggregate. Attapulgite has unique colloidal properties such as good dispersion, high temperature resistance, and salt and alkali resistance, and a relatively high adsorption and decolorization ability. In order to more accurately understand the properties of attapulgite clay, it is necessary to detect the bulk density of attapulgite clay. The bulk density refers to the mass per unit volume of granular materials or powdery materials in a natural accumulation state. The bulk density can be divided into loose bulk density and tapped bulk density.

[0003] In the prior art, the patent number is CN207336289U, and the name is a tester for the bulk density of attapulgite clay, including a machine base. A support frame is installed at the upper end of the machine base, and a storage cylinder is installed at the upper end of the support frame; a stirring device is installed inside the storage cylinder; a fine-tuning device is installed in the middle of the machine base, a vibration device is installed at the upper end of the fine-tuning device, and a detection cylinder is installed at the upper end of the vibration device. The fine-tuning motor drives the moving block to drive the moving plate to move through a lead screw, realizing the fine-tuning of the device, ensuring that the raw materials in the storage cylinder are evenly and accurately filled into the detection cylinder, and ensuring accurate detection; the stirring motor transmits power through the driving bevel gear and the driven bevel gear, so that the stirring shaft drives the stirring blades to stir, preventing blockage and ensuring that the raw materials are smoothly filled into the detection cylinder; the controller controls the electromagnet to be charged and de-energized, and the magnetic plate moves up and down in the vertical direction under the action of the elastic force of the buffer spring, thereby generating vibration to meet the detection of the tapped bulk density.

[0004] However, the existing devices for detecting the density of attapulgite clay need to be placed on a vibration device for vibration to compact the attapulgite clay, and then record the data. When there is a position offset during vibration and the detection device moves, the attapulgite clay inside the detection device will shift, affecting the data recording. Summary of the Invention

The end of the transverse moving plate 29 is inserted into the sliding groove 27, so that the transverse moving plate 29 can move in the sliding groove 27, playing a limiting role on the measuring tube 3 and making the measuring tube 3 rise. After the measuring tube 3 rises, it is clamped between the clamping plates 9. After the vibration motor 6 vibrates, the measuring tube 3 is driven to vibrate through the vertical rod 7 and the connecting ring 8. The transverse moving plate 29 can keep shaking in the sliding groove 27, and the material of the rubber block 36 enables the second insertion rod 34 to shake in the second insertion hole 35, so as to compact the attapulgite inside the measuring tube 3. And data can be immediately obtained through the transparent plate 18, and the measuring tube 3 does not need to be moved and always remains in a vertical state.
