Description

Technical Field

[0001] This utility model belongs to the field of tank truck transportation equipment cleaning technology, and specifically relates to a fully automatic hot water cleaning system for tank trucks. Background Technology

[0002] Chemical products and oils are currently mainly transported using tank trucks, with common methods including truck tank trucks and rail tank trucks. When transported products need to be changed or used for an extended period, the interior of the tank truck needs to be cleaned to ensure cleanliness and prevent contamination of the products during transport. Currently, the mainstream method for cleaning tank trucks is using steam as the cleaning medium, employing manually operated spray guns and other equipment to clean the inner walls. However, this method has several drawbacks and risks: 1. Steam, as a high-temperature and high-pressure medium, easily causes burns to personnel; 2. Due to the special physical and chemical properties of steam, pipelines with a diameter of DN50 or larger require pressure monitoring, increasing operating costs; 3. Manual operation of spray guns for internal work results in low efficiency and may involve working in the confined space inside the tank truck, increasing the risk of suffocation and poisoning. In fact, except for a small number of heavy and high-viscosity materials (such as asphalt and marine fuel oil), most chemical products and oils can be effectively cleaned without an environment above 100°C. Therefore, the fully automatic hot water cleaning method for tank trucks can solve most of the tank truck cleaning needs, avoid safety risks, and reduce operating costs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a fully automatic hot water cleaning tanker system, including a production water pipe, a steam pipe, a hot water mixing tank, a hot water outlet pipe, a multi-stage pump, and a tank cleaner.

[0004] Two hot water mixing tanks are provided. The inlet of each hot water mixing tank is connected to a water generation pipe and a steam pipe, respectively. The outlets of the two hot water mixing tanks are respectively provided with hot water outlet pipes. Each hot water outlet pipe is equipped with a multi-stage pump. Each multi-stage pump leads out multiple branch pipes for cleaning. Each branch pipe is connected to a tank cleaner through one end. The tank cleaner is connected to a tank truck for cleaning.

[0005] Furthermore, the tank washing device includes an installation plate, an automatic rotating plate, and a hydraulic arm; the hydraulic arm is used to support the branch pipes, and the installation plate is suspended at the head end. The installation plate is installed at the top inlet of the tank truck, and the branch pipes extend into the tank truck through the installation plate. Hot water dual nozzles are installed at the end of the branch pipes. The hot water dual nozzles are installed on an automatic rotating plate, which drives the hot water dual nozzles to rotate.

[0017] Two hot water mixing tanks are provided. The inlet of each hot water mixing tank is connected to a water generation pipe and a steam pipe, respectively. The outlets of the two hot water mixing tanks are respectively provided with hot water outlet pipes. Each hot water outlet pipe is equipped with a multi-stage pump.

[0018] Furthermore, the tank washing device includes an installation plate, an automatic rotating plate, and a hydraulic arm; the hydraulic arm is used to support the branch pipe, and the installation plate is suspended at the head end. The installation plate is installed at the top inlet of the tank truck, the branch pipe extends through the installation plate into the tank truck, and a hot water dual nozzle is installed at the end of the branch pipe. The hot water dual nozzle is installed on an automatic rotating plate, which drives the hot water dual nozzle to rotate.

[0019] Furthermore, a sealing ring is provided between the mounting plate and the inlet mounting location for sealing.

[0020] Furthermore, it also includes a sewage discharge unit, comprising a vacuum unit, an oil discharge unit, and a wastewater discharge unit; among which,

[0021] The oil discharge unit includes a vacuum residual oil tank and multiple vacuum wastewater tanks; among which,

[0022] The vacuum residual oil tank 7 is equipped with an oil inlet pipeline, an air extraction pipeline, and an oil outlet pipeline. The oil extraction pipeline is located at the top of the vacuum residual oil tank and its other end is connected to the inside of the tank truck. It uses a vacuum environment to draw residual oil from the tank truck into the vacuum residual oil tank. The oil outlet pipeline is located at the bottom of the vacuum residual oil tank and its other end is connected to a transfer pump to remove the residual oil inside. The air extraction pipeline is located at the top of the vacuum residual oil tank and is equipped with a vacuum pump 9. The gas is discharged into the atmosphere through a gas-water separator at the end.

[0023] Vacuum sewage tank 8, each vacuum sewage tank is equipped with a sewage extraction pipeline, a sewage discharge pipeline and an air extraction pipeline. The sewage extraction pipeline is connected to the tank truck, and the sewage after cleaning in the tank truck is drawn into the vacuum sewage tank through a vacuum environment. It is then discharged to the discharge point through the sewage discharge pipeline set at the bottom and the conveying pump 10 set on the pipeline. The air extraction pipeline is located inside the vacuum sewage tank at one end and connected to the vacuum pump at the other end.

[0024] The specific process is as follows:

[0025] First, by turning on the vacuum pump, the air and residual oil inside the tanker are extracted into the vacuum residual oil tank of the oil unit through the oil inlet pipeline;

[0026] The newly added hot water mixing tank utilizes steam and production water for hot water mixing. It can mix hot water at different temperatures according to the characteristics of different chemical products, reducing heat source loss. After mixing, a multi-stage pump (hot water booster pump) pressurizes the hot water and delivers it to the tank washing unit. The tank washing unit is equipped with dual hot water nozzles, an automatic rotary actuator, a hydraulic arm, and sealing rings. Depending on the operating environment and explosion-proof requirements, the automatic rotary actuator can use compressed gas or electricity as a power source, or adopt existing commercially available rotary multi-nozzle systems. The overall outer pipe of the equipment is similar to the loading arm of a tank truck, supported by a hydraulic arm, allowing operators to easily insert the nozzles into the tank truck. The base is sealed tightly with the pipe opening using sealing rings. To prevent oil and gas leakage due to high temperatures during tank truck cleaning, a gas collection device needs to be added to the manhole of the tank truck. This solution includes a vacuum residual oil tank, which, in conjunction with the negative pressure generated by the vacuum pump, extracts the oil and gas in a sealed manner. The oil and gas then enters the vacuum residual oil tank for processing, and finally passes through a steam-water separator before being vented at a high point. The vacuum residual oil tank device can be equipped with a waste gas treatment device that uses activated carbon and other media adsorption processes to effectively adsorb harmful substances in the oil and gas, ensuring compliance with environmental protection requirements for atmospheric emissions.

[0027] The bottom drain pipe of the tanker truck is connected to the sewage and sludge systems via a flexible sewage pipeline. After connection, a vacuum pump is used to extract the sludge from the tanker truck into a vacuum residual oil tank. After the sludge extraction operation, tank washing machine, and exhaust gas collector are connected, the operator turns on the operating switch. The hot water dual nozzles, according to the preset program on the industrial control computer, perform hot water rotational spraying and cleaning inside the tanker truck. At the same time, the tanker truck's drain pipe is switched to the sewage system to promptly discharge the wastewater generated from the hot water cleaning into the vacuum sewage tank. After the cleaning operation is completed, the sludge is pumped to the plant's sludge storage or treatment device, and the wastewater is discharged into the plant's sewage network for unified treatment. To ensure the safe operation of the equipment, supporting equipment such as level gauges, temperature transmitters, and pressure gauges are also provided.
