Description

Technical Field

[0001] This utility model relates to the field of heat transfer oil repair technology, and in particular to a mixing device for heat transfer oil repair. Background Technology

[0002] Thermal oil, also known as organic heat transfer fluid, is used as a heat transfer medium for indirect heat transfer. It is mainly used in industries such as petrochemicals, light chemical industry, rubber and plastics, papermaking and printing.

[0003] Heat transfer oils are generally classified into mineral oil-based and synthetic types. Mineral-based heat transfer oils are mainly composed of alkanes and cycloalkanes, which are less toxic and cheaper, but they are easily oxidized and decomposed at high temperatures, limiting their use to below 300°C. Compared to mineral-based heat transfer oils, synthetic heat transfer oils have advantages such as higher initial boiling point, narrower boiling range, less high-temperature cracking, better high-temperature thermal stability, and greater safety and reliability. As the operating temperature of heat transfer oils increases, their high-temperature thermal stability becomes particularly important. When heat transfer oils operate in high-temperature, highly oxidizing environments and are directly exposed to air for extended periods, they are prone to cracking and oxidation reactions. This causes the base oil in the heat transfer oil to deteriorate, and additives are consumed, resulting in increasingly poor thermal stability. Eventually, the oil fails to meet operating requirements, posing significant safety hazards to equipment.

[0004] Enterprises are increasingly choosing the purification and reuse of heat transfer oil. However, due to the loss of additives during the use of heat transfer oil, the restoration of functional additives in purified heat transfer oil is urgently needed to meet the operational requirements of equipment. Since the heat transfer oil to be blended is waste heat transfer oil, conventional lubricating oil blending devices cannot meet the cleanliness requirements of the restored product. Therefore, in view of the above situation, there is an urgent need to develop a device for heat transfer oil restoration to overcome the shortcomings in current practical applications, thereby realizing the recycling of waste heat transfer oil and achieving cost reduction and efficiency improvement. Utility Model Content

[0005] In view of the shortcomings and deficiencies of traditional purification technology in that the heat transfer oil cannot meet the equipment operation standards and the loss of functional additives in the heat transfer oil, the present invention provides a blending device for heat transfer oil repair.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A blending device for repairing heat transfer oil includes an additive storage tank, a blending tank, a filter, and a finished oil storage tank. The additive storage tank and the blending tank are connected by a pipeline. A metering pump is installed on the pipeline between the additive storage tank and the blending tank. The blending tank and the filter are connected by a pipeline. The filter is connected to the finished oil storage tank by a pipeline. An oil pump is installed on the pipeline between the blending tank and the filter. The filter uses a wood fiber filter element.

[0008] Wood fiber filter cartridges are environmentally friendly, biodegradable, and renewable. They are environmentally friendly, produce no secondary pollution, and have certain value in carbon reduction, energy conservation, and pollution reduction projects, thus better responding to national environmental protection policies.

[0009] In a preferred embodiment, the mixing tank includes a tank body and a motor. The tank body is equipped with a stirring paddle, and the top of the tank body is equipped with an oil inlet. The motor is used to drive the stirring paddle.

[0010] This mixing device mainly consists of an additive tank, a metering pump, a mixing tank, an oil pump, and a filter. The additive tank mainly stores the functional additives for the heat transfer oil. The metering pump adds the additives to the mixing tank according to the additive formula of the heat transfer oil to be repaired, in a specific ratio and sequence. The motor on the mixing tank is a variable frequency motor, which can adjust the stirring speed according to the actual application. During operation, the motor drives a double-layer stirring paddle to efficiently achieve thorough mixing of the additives and the heat transfer oil.

[0011] The mixing tank is equipped with an additive inlet and an oil inlet at the top. The additive inlet is connected to the pipeline of the metering pump for adding additives; the oil inlet is used for direct oil filling.

[0012] The bottom of the mixing tank is equipped with a heat transfer oil discharge port, which is directly connected to the pipeline.

[0013] The filter has several built-in wood fiber filter elements with a filtration accuracy of 1μm-10μm to ensure the cleanliness of the heat transfer oil end process.

[0014] In a preferred embodiment, a heating coil is provided on the side wall of the tank.

[0015] The heating coil is a temperature-adjustable ceramic heating coil.

[0016] In a preferred embodiment, a ball valve is provided between the mixing tank and the oil pump.

[0017] Ball valves are used to regulate the opening and closing of the pipeline between the blending tank and the oil pump at different times.

[0018] Specific process: First, by analyzing the various physicochemical properties of the heat transfer oil to be repaired, a functional additive process package is designed. Before blending, the heat transfer oil is added to the blending tank, and the heating coil temperature is set to 60℃ to ensure the optimal blending temperature of the additives. At the same time, the variable frequency motor is turned on, and the frequency is set to 20Hz-50Hz for heating and pre-stirring. After the temperature is constant, the metering pump is turned on, and the lubricating oil and each functional additive in the process package are added to the blending tank in the correct proportion and order. The mixture is stirred at a constant temperature of 60℃ for 30 minutes. After all the additives have been added and blended, the heating coil and motor are turned off, the ball valve at the bottom of the blending tank is opened, and the oil pump is turned on to pump the repaired heat transfer oil to the filter for final supplementary filtration to ensure the cleanliness of the finished heat transfer oil. After filtration, the finished heat transfer oil is transferred to the finished oil storage tank for storage, thus completing the heat transfer oil repair process.

[0019] The beneficial effects of this utility model are:

[0020] This solution utilizes a combination of a mixing tank and a filter in series to repair the heat transfer oil; it achieves the recycling and regeneration of waste heat transfer oil. The end filter is a wood fiber filter element, which ensures the cleanliness of the repaired heat transfer oil, and is environmentally friendly and recyclable. Furthermore, the repair and reuse of waste lubricating oil has significant economic benefits. Attached Figure Description
