Description

Technical Field

[0001] This utility model relates to a waste oil treatment device, and more particularly to a waste oil heat dissipation treatment device. Background Technology

[0002] In modern industrial systems, core production processes such as machinery manufacturing, petroleum refining, automobile repair, and power equipment maintenance all generate large amounts of waste oil. As a hazardous waste generated in industrial production, waste oil's flammability, oxidizability, and electrostatic accumulation characteristics pose a serious challenge to the safety of storage equipment.

[0003] Waste oil exhibits significant hazardous chemical characteristics during storage. For example, residual metal catalysts (such as Fe and Cu ions) in waste oil undergo autocatalytic oxidation with polycyclic aromatic hydrocarbons in the presence of oxygen, leading to an increase in oil temperature. Waste oil is prone to generating static electricity during dumping, stirring, and pipeline transportation, especially waste oil containing solid particles.

[0004] Conventional oil storage tanks in the prior art are usually vertical cylindrical tanks welded from carbon steel or stainless steel, with a conical or flat bottom structure. They rely on natural convection for heat dissipation and prevent static electricity generation by grounding the oil storage tank itself.

[0005] Although this waste oil treatment device can store waste oil, it still has the following drawbacks:

[0006] 1. Due to the complex composition of waste oil, which usually contains water, chemical solvents, metal ions, sulfides, etc., waste oil will separate into layers due to gravity during storage, resulting in poor heat convection and heat dissipation.

[0007] 2. At the same time, metal ions and sulfides in waste oil will accelerate the oxidation of waste oil, causing the oil temperature to rise and then spontaneously combust, resulting in poor safety.

[0008] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0015] The oil storage tank includes a tank body and a cover plate. The tank body is a barrel-shaped structure with the opening facing upwards. The cover plate is sealed to the opening end of the tank body. The waste oil outlet is located at the bottom of the tank body.

A cavity for containing coolant is formed between the heat dissipation device and the outer wall of the tank.

The power output shaft of the motor is coaxially mounted with the tank body. The power output shaft of the motor passes through the cover plate and is sealed to the cover plate. The end of the power output shaft of the motor is provided with stirring blades. The stirring blades of the stirring device are located near the bottom of the tank body.

[0018] The processing device also includes multiple support seats, which are uniformly fixed on the outer wall of the heat dissipation device along the circumferential direction.

[0019] The tank body also has two thermometer ports and two liquid level ports on its side wall. One of the thermometer ports is used to install a local thermometer, and the other thermometer port is used to install a remote thermometer.

[0020] One of the liquid level gauge ports is located near the top of the tank and is used to install a high-level liquid level gauge, which is used to issue an alarm when liquid is detected to prevent the tank from overflowing.

[0021] Another level gauge port is located near the top of the tank for installing a low-level level gauge, which is used to issue an alarm when no liquid is detected to prevent the tank from being evacuated.

[0022] The bottom of the tank is provided with a sampling port, and the cover plate is provided with a spare port.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. This utility model discloses a waste oil heat dissipation treatment device, comprising an oil storage tank, a heat dissipation device, and a stirring device. The oil storage tank is a vertical tank with a waste oil inlet, a nitrogen inlet, an antistatic agent inlet, and a flare port at the top. A waste oil outlet is located at the bottom. Nitrogen and antistatic agent are injected into the oil storage tank through the nitrogen and antistatic agent inlets, reducing static electricity generation and venting air to prevent ignition sources and oxides from appearing inside the tank, thus preventing spontaneous combustion of the waste oil.

[0028] 3. In the waste oil heat dissipation treatment device of this utility model, a stirring device for stirring waste oil is provided. By stirring the waste oil regularly, the waste oil and antistatic agent can be fully mixed. At the same time, it prevents the viscosity of the oil from increasing after oxidation, which would lead to difficulty in heat dissipation and thus local overheating and spontaneous combustion of the waste oil.
