Description

Technical Field

[0001] This utility model relates to a cleaning device for tank trucks transporting hazardous waste. Background Technology

[0002] Hazardous waste disposal companies typically use tank trucks to transport large quantities of liquid hazardous waste. These tank trucks safely transport the liquid hazardous waste to the unloading area. During unloading, staff closely monitor the process to ensure the waste smoothly enters the tank area. After unloading, if any waste residue is found, manual cleaning is necessary to prevent environmental impact and subsequent treatment. Manual cleaning requires specialized operators wearing protective clothing. They must climb ladders to the top of the tanks and use atmospheric or even high-pressure water guns through manholes to thoroughly clean any remaining waste. During cleaning, operators strictly adhere to relevant safety operating procedures to ensure their own safety and environmental safety. This operation is highly dangerous and difficult, demanding significant physical strength and concentration from the operators, and carries risks such as falls from heights and contact with hazardous chemicals. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cleaning device for tank trucks transporting hazardous waste. It replaces manual labor with machinery, reduces the human workload, reduces human contact with hazardous waste, and reduces the impact of hazardous waste on the health of operators.

[0004] The purpose of this utility model is achieved as follows: a cleaning device for tank trucks transporting hazardous waste, installed on an unloading platform, includes two guide rails, a robot, a high-pressure nozzle, and control equipment; wherein,

[0005] Two guide rails are mounted one above the other on the front surface of a crossbeam, which spans between two columns supporting the roof of the unloading platform. The height of the crossbeam is greater than the height of the manhole of the tank truck.

[0006] The robot includes a base, a rear arm, and a forearm; the base is mounted between two guide rails via at least one pair of active pulleys and one pair of driven pulleys, and a pulley drive motor is mounted on the active pulleys; the rear arm is hinged to the base; the forearm is hinged to the other end of the rear arm;

[0007] The high-pressure nozzle is installed at the lower end of the robot's forearm;

[0008] The control device includes a water pump, a monitoring camera, and a controller; the inlet of the water pump is connected to a water source, and the outlet of the water pump is connected to the inlet of the high-pressure nozzle via a hose passing sequentially through the robot's base, rear arm, and forearm; the monitoring camera is mounted on the robot's rear arm; the controller is connected to the pulley drive motor, the robot, the high-pressure nozzle, the water pump, and the monitoring camera via signal lines.

[0009] The aforementioned cleaning device for hazardous waste transport tank trucks includes a controller installed in a control cabinet, the door of which is equipped with a display screen and control switches; both the control cabinet and the water pump are located on the ground of the unloading platform.

[0010] The features of this utility model's cleaning device for hazardous waste transport tank trucks are:

[0011] 1. Reduce the time operators spend working at heights, keeping them on the ground most of the time to reduce the risk of falls.

[0012] 2. Replace manual labor with machinery to reduce the workload on workers;

[0013] 3. Reduce human contact with hazardous waste and mitigate its impact on the health of operators. Attached Figure Description
