The cleaning shower head is set above the cleaning bucket and connected to the hot water tank. There is a valve between the hot water tank and the cleaning shower head. The second solenoid valve; the water tank and the hot water tank are connected to the main water inlet pipe; the control system is composed of a PLC controller, and the PLC controller is connected to the first solenoid valve and the second solenoid valve.

The purpose of the present invention can also be further achieved through the following technical measures.

In the aforementioned floating coal sample cleaning device, the cleaning device is provided with several cleaning units.

In the aforementioned floating coal sample cleaning device, the circulating vacuum system is further provided with a buffer tank, and the buffer tank is arranged between the vacuum pump and the solenoid valve one.

The present invention cleans the zinc chloride on the coal sample through the cleaning unit in the cleaning system, places the coal sample in the cleaning hopper in the cleaning unit, opens the solenoid valve 2, and pours hot water onto the coal sample through the cleaning shower head. After standing still, open the solenoid valve 1, the negative pressure in the buffer tank will suck the water in the cleaning bucket, and all the water will flow to the bottom of the cleaning bucket and be discharged through the drain pipe. The above cleaning process will be continuously circulated through the PLC controller to remove The zinc chloride on the surface of the coal sample does not need manual operation in the cleaning process, and the automatic cleaning control is realized through the control system, and multiple cleaning units can be set up to clean multiple coal samples at the same time, greatly improving the cleaning efficiency. The invention is equipped with a buffer tank , the vacuum pump ensures that the negative pressure in the buffer tank is kept within a certain range in real time, and the buffer tank can effectively prolong the service life of the vacuum pump; the invention has compact structure, few parts, low cost, convenient installation, simple maintenance, convenient operation and high efficiency .

The invention, with advantages and characteristics, will be illustrated and explained by the following non-limiting description of preferred embodiments, given by way of example only with reference to the accompanying drawings.
