Coal yard coal dump density measuring device

Abstract

The invention discloses a coal yard coal dump density measuring device. The coal yard coal dump density measuring device comprises a base and is characterized in that a measuring box and a standard gas distribution box which are communicated with each other are arranged on the base; a first one-way valve is arranged between the measuring box and the standard gas distribution box, and the measuringbox is provided with a gas pressure sensor for detecting the pressure of the measuring box; the standard gas distribution box is connected with a liquid standard box; a second one-way valve is arranged between the standard gas distribution box and the liquid standard box, and the standard gas distribution box is provided with a third one-way valve; a piston plate capable of pushing liquid into the standard gas distribution box is arranged in the liquid standard box and connected with an air cylinder push rod arranged on a measuring rack; the liquid standard box is further connected with a liquid supply box. The coal yard coal dump density measuring device has the advantages that coal dump density can be accurately and fast measured, the coal yard checking result is accurate, the workloadof density measuring is reduced greatly, manpower is saved greatly, density measuring efficiency is increased, accurate reference is provided for enterprise production and operation management, and the device is high in practical value and popularization value.

Description

technical field [0001] The invention relates to the field of density detection technical equipment, in particular to a coal bulk density measurement device in a coal yard. Background technique [0002] Density is a very important physical quantity, and it has important utilization value in many fields. In the coal use and production areas, the coal needs to be panned every month or quarter, and the coal density should be measured. Coal yards usually use fixed "specific gravity cylinder compaction method", large container measurement method, and "standard bucket method measurement" to measure density. During the compaction process, since the loading truck conducts multiple density tests on the coal at the bottom edge of the coal pile, due to the large distribution area of ​​the coal pile, the sampling coverage of the coal pile is relatively limited, and there are differences in the density of the upper, middle and lower parts of the coal pile , not only there is a large err...
