Description
Technical Field
The utility model relates to a spare part machine-shaping field, concretely relates to steam blackening furnace with waste oil recovery device.
Background
In order to improve the corrosion resistance of the workpiece, it is required to perform a blackening treatment. Generally, a steam blackening treatment process is adopted, namely, the steam reacts with a workpiece under certain temperature and pressure conditions, so that a compact oxide film is generated on the surface of the workpiece, the oxide film has good antirust capacity, the surface hardness of the workpiece can be improved, and the wear resistance of the workpiece is improved. The mesh belt type continuous steam blackening furnace is furnace body equipment used in a steam blackening treatment process. Before the blackening treatment by using water vapor, the workpiece to be treated needs to be treated with oil (generally, the workpiece is immersed in oil for treatment to prevent rusting), and waste oil is generated in the process of preheating later. China is a large country for producing and using mesh belt type continuous steam blackening furnaces, so a large amount of waste oil is generated. Waste oil in the blackening product is gasified in the market at present, and a large amount of oil smoke is generated although the waste oil is treated.
In recent years, energy conservation and emission reduction are vigorously advocated by the nation. The problem of waste oil generated by the steam blackening furnace is solved, the response to national energy-saving and emission-reducing policies is realized, and the pollution of oil smoke to the environment can be reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the waste oil problem of the steam blackening furnace, the utility model discloses a steam blackening furnace with a waste oil recovery device, which comprises a feeding section, a preheating section, a transition section, a blackening section, a cooling section and a discharging section which are connected in sequence; a waste oil recovery device is arranged on the transition section; the waste oil recovery device comprises an oil receiving cover, a waste oil pipeline and an oil receiving tank which are connected in sequence; the oil receiving cover is arranged below the transition section.
Further, the waste oil pipeline comprises a trough pipeline, and the trough pipeline is a U-shaped pipe, a V-shaped pipe or a W-shaped pipe.
Furthermore, a first valve is arranged on the waste oil pipeline between the oil receiving cover and the trough pipeline.
Furthermore, the first valve is a gravity sensing valve and is set to be in a closed state when power is off; when the weight is sensed to be larger than n when the power is on, the first valve is opened and keeps an opening state until the power is off; n is the weight of the waste oil when the waste oil divides the waste oil pipeline into two spaces at the trough pipeline.
Further, the oil receiving cover is in a funnel shape with a large upper part and a small lower part.
Further, the size of the top opening of the oil receiving cover is 3/4 to be equal to the size of the bottom of the transition section. The large area is beneficial to the liquid oil on the transition section to drip into the oil receiving cover as much as possible.
Further, a second valve is arranged below or at the bottom of the side wall of the oil receiving tank.
Further, the second valve is a gravity sensing valve, and is configured to open and maintain an open state when the sensed weight is greater than m until the second valve is closed after no oil flows out of the second valve; m is the weight of the waste oil in the oil receiving tank, and m is more than 0 kg. In one embodiment, m is the weight of the waste oil when the oil receiving tank is filled with the waste oil. In another embodiment, m is the weight of waste oil when the oil reservoir 3/4 is filled with waste oil.
The utility model has the advantages that: the utility model discloses set up a waste oil recovery device on the changeover portion of steam blackening stove. A large amount of liquid waste oil that workpiece deoiling after preheating section treatment produced through this waste oil recovery unit is collected and is recycled, has reached the reduction oil smoke, retrieves the purpose of waste oil, practices thrift manufacturing cost, environmental protection. The arrangement of the trough pipeline prevents oil smoke from entering the oil receiving tank and ensures that liquid oil enters the oil receiving tank. The arrangement of the first valve is beneficial to storing a certain amount of liquid oil in the oil receiving cover, and then the first valve is opened to ensure that a certain amount of liquid oil is always kept in the trough pipeline, so that the waste oil pipeline is divided into two spaces, and oil smoke is prevented from entering the oil receiving tank. The second valve is arranged to facilitate the discharge of waste oil when the oil receiving tank is full or is about to be full.
The present invention will be further described with reference to the accompanying drawings to fully illustrate the objects, technical features and technical effects of the present invention.
