Description
Technical field
The utility model relates to a kind of fine aggregate MB value detection devices, belong to methylenum careuleum the field of test technology.
Background technique
MB value is determining fine aggregate, fine powder, in miberal powder with the presence or absence of swelling wall rock and determines the entirety of its content
Index.Usually we evaluate the fine powder content in fine aggregate by methylenum careuleum experiment, its test principle is to gathering materials and water
It stirs and is continuously added methylene blue solution in manufactured suspension, after every a certain amount of methylene blue solution of addition, methylenum careuleum is thin collection
Powder in material is adsorbed, and is picked a little suspension with glass bar and is dripped on filter paper and sees whether that free methylenum careuleum radiates
Light blue tinge, judge the absorption situation gathered materials to dye solution.It is tested by tinge, determines the end of addition methylene blue dye
Point, until the dyestuff stops adsorption.This following Railway Project of method: 1, in whipping process, only one paddle exists
Bottom of a cup stirring, the stirring of suspension upper layer is uneven, and then influences the dripping quantity of methylenum careuleum, and experimental result is inaccurate；2, it stirs
Leaf is located at the stirring of beaker cental axial position, and the diameter of paddle is less than beaker diameter, and stirring is not uniform enough, and experimental result is not smart
Really；3, in whipping process, in order to stir more evenly, container must necessarily be placed in stirring axis center, and existing apparatus is needed through artificial mesh
Measuring is set, and it is uneven to operate comparatively laborious and stirring；4, it in whipping process, is not placed on and stirs if mixing power spends big or container
Mix axis center position, container can be easy to shift, paddle and container inner wall collision, cause solution to flash, pollution experimental bench and
Laboratory technician's lab-gown.
Utility model content
Technical problem to be solved by the utility model is: a kind of fine aggregate MB value detection device is provided, to solve existing skill
Art agitating mode stirs unevenly, and data are inaccurate, is easy to make testing stand dirty, container places trouble, and places shakiness
Problem.
The technical solution of the utility model is: a kind of fine aggregate MB value detection device, including pedestal and bracket, the pedestal
Upper setting is fluted, and the diameter of the groove is 1mm bigger than beaker bottom diameter, and the beaker is placed on the groove, and motor is logical
It crosses support frame to be connected with the pedestal, the motor clutch disk, the disk circumference side is connected with drive shaft, the drive shaft
It can move in a circle on the disk, agitating shaft is connected below the drive shaft, is provided with lower paddle on the agitating shaft
With upper paddle, the blade outer edge and the beaker inner wall of the lower paddle and the upper paddle are tangent.
Preferably, switch is provided on the disk.
Preferably, the blade of the lower paddle and the upper paddle is respectively 3-6 piece.
Preferably, the lower paddle and the upper paddle can be around the agitating shaft rotations.
Preferably, the lower paddle is located at the bottom of the agitating shaft, and the upper paddle is located at the lower paddle
The position of top 50-80mm.
Preferably, the detection device is in symmetrical structure, it can while carrying out two groups of MB value detections.
The beneficial effects of the utility model are:
1, the present apparatus is provided with two the same paddles of size and shape on agitating shaft, when paddle rotates, container
Interior solution top and deposited bottom stirring more evenly, avoid one paddle of the prior art and stir non-uniform problem；
2, the present apparatus drives agitating shaft to move in a circle in drive shaft, and agitating shaft drives paddle to do circumference around walls of beaker
Movement, so that the solution in flask is stirred, stirring is more evenly；Prior art agitating shaft is avoided only to revolve at beaker center
Turn, solution stirring is uneven, and mixing time is long, the inaccurate problem of data；
3, the paddle of the present apparatus can be around agitating shaft rotation, so that stirring is more abundant；
4, the present apparatus is equipped with a groove on bottom plate, and diameter is consistent with container bottom diameter, the blade of dot and paddle
Always point-blank, this set is more stable for inside edge, is more convenient container and places；
5, symmetrical structure can be set into the present apparatus, can carry out two groups of tests simultaneously, improves test efficiency.
