Problems solved by technology
This method is simple and fast, but it also has the following disadvantages: ①This method is not detected by manual sampling on the production flow line, and cannot guide production in time; ②The ore specific gravity during sampling may not be the ore specific gravity shown on the ore specific gravity table. Coupled with human operating errors, the error is large

Embodiment Construction
[0020] Depend on Figure 1-2 It can be seen that the slurry density meter includes an iron pipe probe 1 with an inner diameter of Φ15mm-40mm and a length of 40cm or 80cm. The iron pipe probe 1 is connected to one end of the measuring instrument 4 through a rubber conduit 3 with a length of 4 meters to 5 meters. The other end of instrument 4 is connected with plexiglass tube 5 . The upper end of the plexiglass tube 5 is provided with a plastic float 6 with a diameter of 6 mm and a length of 200 mm. The upper end of the float 6 is pasted with a metal sheet 7, and the metal sheet used in this embodiment is an iron sheet. 20mm and 120mm on the float 6 are respectively provided with pin points in three directions separated by 120°, and a non-contact proximity switch 8 is provided above the metal sheet 7 . Measuring instrument 4 is provided with inner cylinder 2, and the area of inner cylinder 2 is 100 times of the sectional area of plexiglass tube, and its outer periphery is p...

Abstract
The invention relates to an ore pulp densitometer which comprises an iron pipe probe, wherein the iron pipe probe is connected with one end of a measurer through a guide pipe; the other end of the measurer is connected with an organic glass pipe; a buoy is arranged in the upper end of the organic glass pipe; a metal sheet is arranged at the upper part of the buoy; a contactless near position switch is arranged above the metal sheet; an inner barrel is arranged in the measurer; a double-head helical slot is arranged on the peripheral edge of the inner barrel; a gas chamber is reserved above the inner barrel; the outer barrel sleeves the inner barrel; a clearance is reserved between the outer barrel and the inner barrel; the outer barrel is closed and fixed with a closing plug through an outer hoop. The ore pulp densitometer can realize on-line measurement and is high in measurement precision and long in service life.
Description
technical field [0001] The invention relates to an ore pulp density meter used in a mine dressing plant, in particular to an ore pulp density meter with equal pressure strength of ore pulp at a specified depth. Background technique [0002] Pulp concentration generally refers to the weight percentage of small ore particles in water. There are many methods for measuring the concentration of pulp in mine concentrators. On-site sampling inspection is a fixed-volume concentration pot weighing look-up method; non-contact continuous measurement method is to measure the attenuation of g-rays penetrating the measured substance (ore particles), and calculate the percentage of this substance. There are also pressure difference method, water column balance method, etc. The most commonly used methods are concentration spoon sampling and drying drying weighing method. Concentration pots are used in the concentrator to weigh the pulp, and the pulp concentration can be obtained from the ...
