Reaction storage electric energy or to power supply for electrical equipment.Lead storage battery is made of pole plate, partition, electrolyte, battery case etc..Pole plate
It is the core of lead storage battery, the chemical reaction of battery charge and discharge mainly relies on active material and electrolysis on pole plate
Liquid carries out, and pole plate is divided into positive plate and negative plate, and positive plate and negative plate are all by grid and coated in the active material on grid
I.e. lead plaster forms.
The main component of lead plaster is lead powder, and lead powder is process by lead pig, examine the quality of lead powder generally use oxidizability,
Apparent gravity inhales three indexs of acid value.The apparent gravity of lead powder is to include dead air space contained by particle inside according to lead powder particle
Volume, counted density become apparent gravity (i.e. apparent density).
The method of measurement apparent density of lead powder is generally：Sieve by lead powder Jing Guo certain mesh number after screen analysis, is received with funnel
Collect the lead powder fallen to strike off until natural packing completely collects measuring cup along rim of a cup, measures lead powder weight, calculate apparent density.
It is this measurement apparent density of lead powder method there are the problem of：1. ambient humidity has apparent shadow by sieve to lead powder
It rings, finally influences test result；2. monolith is slided and is uniformly slided and significantly affects to result when collection funnel, therefore this method again
Reproducibility and less reproducible, there is test result to illustrate this problem；3. sieving lead powder overlong time, efficiency is influenced；4. density
Test result and the relevance of microcosmic test be not strong.
Utility model content
The utility model is directed to the deficiencies in the prior art, provides a kind of for detecting the dress of lead powder pressurization density
It sets, detects the pressurization density of lead powder by using the device as an index of lead powder quality.
It is a kind of for detecting the device of lead powder pressurization density, including measuring cup and for by the lead powder pressure to be detected in measuring cup
Real pressing plate, the measuring cup are two-part structure, are mutually socketed between upper section and lower section.Upper section is identical as the internal diameter of lower section.Under
Section has bottom of a cup, so only upper opening, then both ends are all open upper section, and upper section is mutually socketed with lower section, for detachable cooperation.
The outer diameter of the upper section is greater than the outer diameter of lower section, the socket part that there is the upper section internal diameter to expand, cooperate with lower section.
The socket part internal diameter of upper section expands, and forms a step structure, is socketed with lower section oral area.
The device, including pedestal, the pedestal are equipped with the locating slot cooperated with measuring cup.
The pedestal is equipped with bracket, and the bracket includes the riser and horizontally disposed transverse slat set on pedestal side,

Specific embodiment
As shown in Figures 1 to 3, a kind of for detecting the device of lead powder pressurization density, including measuring cup and for will be in measuring cup
Lead powder to be detected compacting pressing plate 4, measuring cup be two-part structure, be divided into upper section 1 and lower section 2, phase between upper section 1 and lower section 2
Mutually socket.Upper section 1 is identical as the internal diameter of lower section 2.Lower section 2 has bottom of a cup, so only upper opening, upper section 1 then all open by both ends
Mouthful, upper section 1 and lower section 2 are mutually socketed, for detachable cooperation.The outer diameter of upper section 1 is greater than the outer diameter of lower section 2, and upper section 1 has internal diameter
The socket part 3 for expanding, cooperating with lower section 2.3 internal diameter of socket part of upper section 1 expands, and a step structure is formed, with 2 oral area of lower section
Socket.The upper section 1 of measuring cup and the depth ratio of lower section 2 are 1: 1~2, and the depth of upper section 1 does not include the height of socket part 3, because of set
The height of socket part 3 is Chong Die with lower section 2, does not calculate in the depth of dress lead powder.
