Description

Technical Field

[0001] This application relates to the technical field of oil extractors, and more particularly to a centrifugal oil extractor. Background Technology

[0002] Oil removal machines typically employ a low-speed rotating oil removal drum with uniform feeding from the top, ensuring that the items are evenly loaded into the drum. The drum is then automatically controlled by a frequency converter, gradually increasing its speed to the operating speed. The oily items are centrifuged at high speed, and the oil is separated from the items by the porous drum wall. The separated oil is thrown to the inner wall of the outer drum, collected, and discharged from the outlet to the oil collection tray, thus completing the oil removal process.

[0003] Patent CN222490485U discloses an object degreasing machine, including a main body placement support frame and a degreasing protective support frame. The degreasing protective support frame has a degreasing component inside and a degreasing protective component at the top. The degreasing protective support frame includes a main body support base plate at the bottom. The upper end of the main body support base plate is connected to a degreasing main body support frame through a shock-absorbing isolation seat. An degreasing outer barrel is located in the middle of the degreasing main body support frame.

[0004] Regarding the aforementioned technologies, the applicant believes that after centrifugation to remove oil, some oil residue still adheres to the object and is difficult to separate by centrifugation, which can easily affect the purity of the object and make it difficult to meet the needs of subsequent processing. Utility Model Content

[0005] In order to improve the oil removal effect and increase the purity of the materials to meet the needs of subsequent processing, this application provides a centrifugal oil remover.

[0006] The centrifugal oil separator provided in this application adopts the following technical solution: A centrifugal oil extractor includes a frame, within which a centrifugal oil extraction section and an oil suction device are provided.

The oil suction pressure plate is installed on the upper part of the oil suction seat, and oil-absorbing cotton is placed opposite the oil suction pressure plate and the oil suction seat. The oil suction pressure plate can be lowered and abut against an object inside the oil suction seat.

[0007] By adopting the above technical solution, after the centrifugal degreasing unit performs the main degreasing work on the object, an oil suction seat is further set up to place the object, and the oil suction plate and the oil-absorbing cotton on the oil suction seat abut against both sides of the object to further absorb the remaining oil on the surface of the object, so as to improve the purity of the object, provide purer raw materials for subsequent processing, and reduce waste oil to a greater extent, thereby reducing the pollution of the environment by oil in further processing.

[0008] Preferably, a guide hopper is fixed on the side wall of the frame, located on one side of the centrifugal degreasing section and above the oil suction seat. The objects in the centrifugal degreasing section enter the oil suction seat through the guide hopper, and an oil-absorbing cotton is spread inside the oil suction seat.

Another oil-absorbing cotton is disposed below the oil suction pressure plate.

[0009] By adopting the above technical solution, the mounting frame supports the drive cylinder and the oil suction plate. The object in the centrifugal degreasing section enters the oil suction seat through the guide hopper. First, the oil absorbent cotton in the oil suction seat absorbs the oil below the object. Then, the drive cylinder drives the oil absorbent cotton on the oil suction plate to press down and absorb the oil above the object, thus more thoroughly removing the oil adsorbed on the surface of the object and improving the purity.

A horizontal plate is fixed to the upper part of the discharge section, and abutment plates are fixed to the two opposite inner sidewalls of the oil suction seat at the corresponding positions of the horizontal plate. The insert plate is inserted between the horizontal plate and the abutment plate, and the upper part of the insert plate is bent toward the side away from the oil suction seat. The sidewalls of the discharge section away from the oil suction seat extend obliquely toward each other to form a discharge port.

[0021] By adopting the above technical solution, the discharge section and the oil suction seat are separated by a baffle plate, which facilitates the oil suction operation by separation; the object can be discharged from the discharge port by pulling out the baffle plate.

[0022] Preferably, the centrifugal deoiling section includes a centrifugal drum driven by a motor, an oil-removing drum disposed outside the centrifugal drum and supporting the motor, and a swinging structure.

[0026] In summary, this application includes at least one of the following beneficial technical effects: After the centrifugal degreasing unit performs the main degreasing work on the object, an oil suction seat is set up to place the object. The oil suction plate and the oil-absorbing cotton on the oil suction seat are pressed against both sides of the object to further absorb the remaining oil on the surface of the object, so as to improve the purity of the object, provide purer raw materials for subsequent processing, and reduce waste oil to a greater extent, thus reducing the pollution of the environment by oil in further processing. The mounting bracket supports the drive cylinder and the oil suction plate. The object in the centrifugal degreasing section enters the oil suction seat through the guide hopper. First, the oil-absorbing cotton in the oil suction seat absorbs the oil below the object. Then, the drive cylinder drives the oil-absorbing cotton on the oil suction plate to press down and absorb the oil above the object. The deformation plate and arc-shaped protrusion are set so that when the oil-absorbing cotton comes into contact with the object, it can increase the contact area with the object through deformation, and more thoroughly remove the oil adsorbed on the surface of the object, thereby improving the oil suction effect and improving the oil degreasing purity of the object.
