Description

Density detector

Technical Field

The utility model belongs to the technical field of quality detection of initiating explosive devices, and particularly relates to a density detector.

Background

The density of the explosive is one of the quality control indexes of the explosive, and the explosive is packagedThe density of the packaged emulsion explosive is generally controlled to be 1.05g/cm ³ ～1.20g/cm ³ When the density of the explosive is too small, the packaging material cannot package the explosive, and cannot be used for the water-containing blasting operation, and meanwhile, the explosion performance such as the explosion speed can be reduced. When the density is too high, the detonation sensitivity and the explosion performance of the explosive cartridge are reduced, blind cannons are easy to cause, and potential safety hazards are brought, so that the density of the explosive cartridge is required to be controlled and detected. At present, the density detection of the cartridge is carried out manually, and a drainage method is basically adopted for detecting phi 32mm and below; when the explosive roll with the diameter of more than 32mm is detected, the weight of the explosive roll is weighed, and the diameter and the length of the explosive roll are detected to obtain the explosive roll. The method has the advantages of long detection time, manual operation and large error.

Disclosure of Invention

The present utility model is directed to a density detector to solve the above problems.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a density detector, includes the casing, the upper end of casing sets up the display screen, the display screen is connected with the treater electricity the below of display screen is provided with the weighing transducer, the weighing transducer is also connected with the treater electricity the below of weighing transducer is provided with the measurement frame the below of measurement frame is provided with elevating system and water tank, the water tank is arranged in on the elevating system.

The weighing transducer is also called a weighing module, and is a known passive element, and the function of the weighing transducer is to convert mechanical deformation into an electronic signal.

The method does not need to scratch the cartridge, can detect the whole cartridge by directly placing the whole cartridge on the densitometer, and is simpler in operation compared with the prior art.

And, the uploading of data in real time is preferably enabled by means of existing software.

Description of the embodiments

The utility model will be further described with reference to the accompanying drawings.

Examples

Referring to fig. 1 and 2, a density detector comprises a shell 1, wherein a display screen 2 is arranged at the upper end of the shell 1, the display screen 2 is electrically connected with a processor, a weighing transmitter 3 is arranged below the display screen 2, the weighing transmitter 3 is also electrically connected with the processor, a measuring frame 4 is arranged below the weighing transmitter 3, a lifting mechanism 5 and a water tank 6 are arranged below the measuring frame 4, and the water tank 6 is arranged on the lifting mechanism 5;

in this embodiment, the display screen 2 is a touch screen; the lifting mechanism 5 has a structure shown in fig. 3 and 4, and comprises a lifting frame 51, a servo motor is adopted to provide power for the lifting frame 51, and the lifting mechanism comprises a servo linear module 52 and an SBR guide rail 53, wherein a support backboard 54 is further arranged on the back of the servo linear module 52, and the lifting frame 51 slides up and down in the SBR guide rail 53 under the drive of the servo linear module 52, so that the lifting of the lifting frame 51 is realized;

when in use, a proper amount of water is firstly introduced into the water tank 6, the water tank 6 is placed on the lifting frame 51, the complete cartridge to be measured is placed on the measuring frame 4, and then the lifting mechanism 5 is operated to lift the water tank 6, so that the cartridge on the measuring frame 4 is immersed in the water of the water tank 6.

Measurement principle: (1) When no cartridge is placed, the pool is raised to the density measurement position (lifting mechanism 5 is fully immersed in water), the weight of which is shown as m1; (2) When the cartridge is not placed, the lifting mechanism rises to above the water surface, the weighing device is 0, after the cartridge is placed, the weighing device is m2, and at the moment, the m2 is the weight of the cartridge; (3) Lifting mechanism 5 rises, water in water tank 6 submerges the cartridge to obtain cartridge weight m3, and the system calculates the volume of the cartridge through weight change; (4) Obtaining the density of the cartridge by dividing the weight of the cartridge by the calculated volume;

the calculation formula is as follows: (m 3-m 2)/m 1; the principle is that buoyancy is obtained according to force balance, and the displayed weight x g+buoyancy=the weight of the cartridge per se can be obtained according to force balance; buoyancy = density × g V rows, V rows being the volume of the cartridge itself as the cartridge is fully immersed in water; and calculating the density of the cartridge by buoyancy.

Furthermore, when in use, a proper amount of water is firstly introduced into the water tank 6, and the influence caused by the volume of the measuring frame 4 is eliminated through parameter calibration. And placing the cartridge on a measuring frame, clicking for automatic measurement after the weighing weight value is stable, automatically lifting the lifting mechanism 5 to a set position, and automatically calculating to obtain the density of the cartridge after detecting the weight again.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
