Product Details

Fully automatic asphalt mixture centrifugal extractor reflux typeExtraction method

GSY-V Intelligent Fully Automatic Asphalt Extraction InstrumentIt is mainly suitable for determining the asphalt content (or oil stone ratio) in asphalt mixtures mixed with viscous petroleum asphalt by centrifugal separation method, and can perform preliminary screening of aggregates To evaluate the quality of commercial asphalt during road construction, it is also applicable for detecting the amount of asphalt and asphalt mixture used during old road surveys. It is the equipment of construction units, laboratories, scientific research units, and teaching institutions in the highway transportation industry.

threeFully automatic asphalt mixture centrifugal extractor reflux typeExtraction methodStructural principle

The instrument consists of a chassis, centrifugal separation system, electromagnetic vibration screening system, solvent supply system, and solvent return system

Composed of receiving system, electrical controller, etc.

The chassis is the supporting part of the instrument. There are 4 universal casters on its lower edge, which can move the instrument and have 4

A retractable support that supports the instrument after it is moved into place to protect the wheels.

The centrifugal separation system consists of a centrifugal shaft (equipped with precision ball bearings), a centrifugal cylinder, a centrifugal shaft sleeve, and a receiver

Composed of a collection tank, dual speed motor, high-speed transmission flat belt, etc.

The electromagnetic vibration screening system consists of a vibrating electromagnet, a conical screening seat, an adjustable tightening handle, a sieve

Composed of spray cover and locking nut, etc.

The solvent supply system consists of a liquid supply pipe, solvent pump, electromagnetic directional valve, pump infusion pipe, extraction pipe, and cleaning

Tube composition.

The solvent recovery system consists of a solvent chamber, a solvent recovery chamber, a condenser box, etc.

The solvent chamber is equipped with cooling pipes, direct reading level gauges, and solvent discharge valves.

The upper part of the solvent recovery room is equipped with a cooling grille. The recycling room is equipped with cleaning nozzles, 2 level switches, 3 electric heaters, 2 temperature sensors, level gauges, and mixed liquid discharge valves.

● Cooling water circulation system

The solvent chamber and condensation chamber are equipped with water-cooled coils, which are connected to the water pump through external hoses. The cooling water pressure should be greater than 2 bar, and the water temperature should be below 12 ℃. The upper hose of the condensation chamber is the inlet pipe, and the lower hose of the solvent chamber is the drain pipe. A flow switch is installed at the front of the drainage pipe for water cut-off protection.

4 Precautions for safe use

When the instrument is installed in place, it should be kept in a horizontal position;

2. The instrument should be equipped with a safe and reliable electrical grounding wire;

3. Before use, check the tightness of the high-speed drive flat belt Under normal circumstances, check every 3 working days and make appropriate adjustments by tightening the screw;

Before starting up, the equipment should be manually turned on without any errors, and then the manual test button should be used to jog the equipment. If there are no errors, the equipment can be operated normally;

5. The centrifugal shaft rotates counterclockwise If the phase sequence error indicator light is on, the three-phase wiring of the power supply must be adjusted, otherwise the operation cannot be carried out normally;

Before operating the equipment, it is necessary to ensure the normal supply of cooling water, otherwise automatic operation cannot be carried out (interlocked with automatic operation);

When the centrifuge stops running halfway, the power must be turned off, the centrifuge cylinder must be removed, and any debris must be cleaned It is strictly prohibited to start the centrifugal system with load, otherwise it will damage the centrifugal shaft system;

Before the centrifugal shaft stops running, it is strictly prohibited to open the collection tank cover;

When installing or removing the centrifuge cylinder, the power must be turned off;

10. Regularly discharge high concentration asphalt mixture from the solvent recovery room.
