Fully-automatic cleaning instrument for RTFO (rolling thin film oven) sample-containing bottles

Abstract

The invention discloses a fully-automatic cleaning instrument for RTFO (rolling thin film oven) sample-containing bottles. An annular sound wave washing tank and a sample-containing bottle fixing andcleaning device are arranged in a cleaning instrument box; an ultrasonic generator is arranged in the annular sound wave washing tank, asphalt residues can be dispersed in a cleaning solution by soundwave vibration, asphalt is emulsified, solid particles are separated in time, cleaning brushes are moved towards the inner wall by an upper support bracket, a certain pressure is applied to the innerwall, and stubborn stains can be cleaned by cooperation with ultrasonic wave vibration and high temperature effects in the rotating process of hard brush edges; the residual cleaning solution can betreated by soft brush edges, manual supplementary wiping after cleaning is avoided, and time and vigor of a lab assistant are saved; cleaning parameters of the sample-containing bottle fixing and cleaning device is controlled by a controller, and automatic cleaning can be realized; meanwhile, the multiple sample-containing bottles can be cleaned simultaneously, cleaning efficiency is improved, bottle bodies are fixed by sample-containing bottle chucks, and the problem of rotation of the bottle bodies in the cleaning process is effectively solved.

Description

technical field [0001] The invention relates to an experimental instrument or equipment technology for asphalt materials, which belongs to the field of automatic cleaning equipment, in particular to a fully automatic rotary film oven sample bottle cleaning instrument. Background technique [0002] my country's asphalt and asphalt mixture test regulations often use rotating film oven experiments to evaluate the short-term aging performance of asphalt. In the experiment, about 35g of asphalt was poured into a notched sample bottle, and under the action of high temperature and thermal oxygen, the changes in properties such as the penetration and ductility of asphalt residues were measured. [0003] Oxygenated bituminous film residues often stick to the vials. In order to reduce R&D and production costs, it is necessary to clean and reuse bitumen-contaminated sample bottles. At present, the cleaning method of the sample bottle is usually to pour trichlorethylene into the sampl...

Problems solved by technology

This cleaning method is inefficient, time-consuming and labor-intensive, and organic solvents are harmful to the environment and damage the health of the testers

[0004] In order to solve the problem of low efficiency of manual cleaning and the poisoning of organic solvents to operators, Chinese patent documents CN205214585U and CN203711429U disclose an electric brush for cleaning sample bottles in a rotary film oven and a cleaning method for sample bottles in a rotary film oven. The device includes a handle and a brush body connected by a rotating rod, which can quickly clean the inner wall of the sample bottle driven by a motor; the cleaning device is to add multiple electric brushes, and put the sample bottle upside down on a single electric brush to clean

[0005] Among the above technologies, the handle-type electric brush needs manual operation, and the cleaning cycle is long; the fixed brush head of the cleaning device cannot be scratched against the inner wall, cannot remove high-viscosity asphalt residues, and does not target the bottom of the bottle, the mouth of the bottle, Bottle wall cleaning device

At the same time, when the electric brush head is working, it will pull the bottle body to rotate, and the cleaning effect cannot be guaranteed

After the entire cleaning procedure is over, the sample bottle will have residual cleaning solution, which needs to be further manually wiped, and cannot be put into the next experiment immediately

The cleaning effect needs manual observation and judgment, no automatic analysis

Washing waste liquid is not judged and recycled for pollution degree, and the cost is high
