Description
Technical field
The utility model belongs to the test apparatus or equipment technical field of Load materials, and in particular to one kind is for scraping rotation
Turn the sampler of thin film oven aging bottle sample.
Background technique
Pitch is a kind of widely applied road engineering material, and the quality of performance will directly affect the carrying energy of road
Power, service life etc..Due to the attribute of pitch itself, usually needed in road engineering application under heating conditions with bone
Material rubble is mixed and stirred.In heating mixing process, pitch will lead to due to light components volatilization, oxidation etc. in pitch
Aging etc..This will affect the pavement performance of pitch, and then influence the bearing capacity of road, service life etc..In order to simulate
The influence to ageing of asphalt is mixed and stirred in the engineering of road, China's specification simulates mixing and stirring for pitch using asphalt film oven aging experiments
Ageing process.Thin film oven aging test is that a certain amount of pitch is fitted into aging bottle, is then placed in baking oven rotatable cooking one
It fixes time, then takes out sample and weigh mass loss, do the campaigns such as three norms of pitch after aging, determine the anti-of pitch
Aging, and then guiding construction and design.
When needing to meet horizontal positioned rotation due to aging bottle, the liquid in bottle cannot flow out and code requirement.So
The size that general common 85 type rotary thin film in drying oven aging bottle uses are as follows: high 139.7mm ± 15mm, outer diameter 64mm ± 1.2mm,
Wall thickness 2.4mm ± 0.3mm, 31.75 ± 1.5mm of mouth diameters.This half opening formula cylindrical body aging bottle is toppling over asphalt sample
When be difficult to pour out, being especially sticked to pitch on inner wall is more difficult to collect.And it is long with the sampling difficulty big bring time, cause to drip
Green temperature reduces, and is even more sticked to inside aging bottle, it is difficult to remove.Sampling is caused to be not thorough, test material utilizes insufficient, examination
Personnel's operating difficulties is tested, the problems such as test period is long.
In the research and practice process sampled to aging bottle, the utility model people of the utility model is had found: in order to sample
Quickly, test difficulty conveniently, thoroughly, is reduced, a kind of taking for rotary thin film in drying oven aging bottle sample convenient for sampling is had devised
Sample device.
Utility model content
The purpose of the utility model is to provide a kind of for scraping the sampler of rotary thin film in drying oven aging bottle sample, this takes
It is quickly, conveniently, thoroughly, easy to operate when sample device is used to scrape aging bottle sample, test material can be made full use of, save test
Time, the labor intensity for reducing test people etc..
In order to achieve the above objectives, the utility model adopts the following technical solution:
It is a kind of for scraping the sampler of rotary thin film in drying oven aging bottle sample, including handle and scraper, handle include every
The changeover portion of hot jacket cylinder, insulating sleeve and scraper, the metal handle that insulating sleeve inside is connect with changeover portion；Scraper includes upper half
Partial knife spine, the knife face of lower half portion.
The metal material that the sampler is integrated in addition to insulating sleeve remaining structure, thickness are no more than 10mm.
The insulating sleeve of the handle is the heat-barrier material that high temperature resistant is not less than 200 DEG C, and transition section length is no more than 50mm,
Width is no more than 13mm, and insulating sleeve and its interior metal decreased food are no more than 200mm；
The scraper is no more than 35mm in any two points wire length of transversal cross-section, corresponding to the curved surface circular arc of knife face
Central angle is no more than pi/2, knife face knife spine direction projection width at least 17mm but be no more than 30mm, knife face is of length no more than
155mm。
Due to using the technology described above, the utility model has the beneficial effects that:
A kind of sampler for scraping rotary thin film in drying oven aging bottle sample of the application can inject in aging bottle, scrape
The sample of aging bottle side wall, bottom surface and top surface is got, sample collection is more convenient, more thorough and easy to operate, can accelerate sampling
Time reduces the labor intensity of test people.By the sample in collection aging bottle as much as possible, test material had both been taken full advantage of
Material reduces to obtain enough samples and repeats the number done experiment, and has saved resource, and clean aging bottle for the later period to reduce work
It measures.
Detailed description of the invention
Fig. 1 is a kind of sampler structure signal for scraping rotating thin film aging bottle sample in the utility model embodiment
Figure.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of for scraping the sampler of rotating thin film aging bottle sample, including handle 1 and scraper 2, hand
Handle 1 includes insulating sleeve 3, and changeover portion 4, the metal handle 5 in insulating sleeve 3, scraper 2 includes knife spine 6, knife face 7, changeover portion 4
The metal material being integrated with metal handle 5 and scraper 2, thickness are no more than 10mm, and insulating sleeve 3 is that high temperature resistant is not less than 200
DEG C heat-barrier material, of length no more than 200mm, the of length no more than 50mm of changeover portion 4, width be no more than 13mm, scraper 2 is in transverse direction
Any two points wire length in section is no more than 35mm, and central angle corresponding to the curved surface circular arc of knife face 7 is no more than pi/2, knife face 7
6 direction projection of knife spine width at least 17mm but be no more than 30mm, the of length no more than 155mm of knife face 7.
The use step of the utility model is described further with reference to the accompanying drawing:
