Embodiment Construction

[0006] A tamping method for measuring the density of coke oven briquettes. After the briquettes are tamped and shaped, use a density measuring tube to place them vertically on the specified briquette density sampling point, and then use a hammer to pressurize. When the pressure reaches 250 mm Stop pressurization, at this time, the upper surface of the coal cake is flush with the limit plate set outside the density measuring tube, then take out the density measuring tube, vibrate the coal material in the density measuring tube with a hammer, put it into the measuring cylinder, and use The metering scale measures the coal material to obtain the weight of the coal material, and obtains the tamping density of the coal cake through calculation. The specific calculation formula is as follows:

[0007] ρ=G / πR 2 ×0.25

[0008] ρ——coal cake tamping density kg / m 3

[0009] R—radius (inner diameter) of the density measuring tube, m

[0010] G - the weight of the coal material vibrat...

Abstract

The invention discloses a density measuring technique for tamping-type coke furnace briquette. After being tamped and formed, the briquette is vertically put on the density sampling point of the briquette by using a density measuring tube and then pressurized by a pressure device to the depth of 250mm to stop, and the upper surface of the briquette is in the same level with a limit plate mounted on the outside of the density measuring tube; after that, the density measuring tube is taken out, and then the coal is vibrated out from the density measuring tube and is put into a measuring cylinder, the coal weight is gained by using a measuring device; the tamping density of the briquette is gained by calculating. The invention has the advantage of convenient measurement and operation on site with the deviation of the test result lower than 5 thousandths, as well as the test time shorter than 3 minutes.

Description

1. Technical field: [0001] The invention belongs to a density measurement method, in particular to a tamping type coke oven coal cake density measurement method. 2. Background technology: [0002] Coal cake density measurement is an important item in the coke production process. The accurate control of coal cake density is directly related to the quality of coke and the use of coke users. However, the current traditional coal cake density measurement method has large deviations in measurement results, The shortcomings of long measurement time and inconvenient on-site measurement and operation. 3. Contents of the invention: [0003] The present invention aims to solve the shortcomings of large measurement result deviation, long measurement time and inconvenient on-site measurement and operation existing in the current traditional briquette density measurement method. [0004] A tamping method for measuring the density of coke oven briquettes. When the briquettes are tamped...
