Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and more specifically to a remote adjustment system for a three-phase centrifuge centrifugal pump. Background Technology

[0002] With China's sustained economic growth and rising living standards, the edible oil market has expanded significantly in recent years. Nearly 43 million tons of edible oil are consumed annually in my country, including a potential waste oil production of up to 13 million tons. Waste oil is a major raw material for biodiesel. As global carbon policies continue to advance, especially with tightening regulations, biodiesel and aviation fuel, with their excellent renewability and emission reduction effects, have become important directions for energy transformation in the transportation sector. It is estimated that, based on the EU carbon allowance of €100 / ton, the carbon reduction economic benefit of biodiesel is €283 / ton, while the selling price of waste oil is 5500 yuan / ton.

[0003] Currently, one of the main methods for extracting waste cooking oil from kitchen waste is three-phase separation, using a three-phase centrifuge. Based on the operating principle of a three-phase centrifuge, to ensure the quality of the separated oil, the oil's state must be constantly monitored, and the centrifugal pump adjusted to control the thickness of the liquid ring within the centrifuge, compressing the oil layer to the outlet to achieve oil-water separation. Existing three-phase centrifuges require operators to manually adjust the centrifugal pump in the equipment room; however, the operating environment is harsh (odors, noise), and manual adjustment is time-consuming. Therefore, adding a remote adjustment system for the centrifugal pump is essential.

[0004] Therefore, developing a remote control system for a three-phase centrifugal centrifugal pump that is easy to operate and can improve adjustment efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a remote adjustment system for a three-phase centrifugal centrifugal pump that is easy to operate and can improve adjustment efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A three-phase centrifugal centrifugal pump remote control system includes:

[0008] A centrifuge, wherein a centrifugal pump is connected to the inlet end of the centrifuge;

[0009] An electric push rod, the fixed end of which is connected to the centrifuge, and the movable end which is hinged to the adjusting rod of the centrifugal pump; the extension and retraction of the electric push rod will cause the adjusting rod to rotate.

[0010] A camera is installed at the liquid outlet end of the centrifuge;

[0011] The control component is connected to both the camera and the electric push rod. The images captured by the camera are transmitted to the control component, and the control component controls the electric push rod to perform corresponding actions.

[0012] The beneficial effects of adopting the above technical solution are that it realizes the function of remote adjustment of the centripetal pump, avoids operators from entering the equipment room, improves the working environment, and protects the physical and mental health of the staff; and ensures the stable and reliable quality of the separated oil by monitoring the oil status at the liquid outlet in real time through a camera.

[0013] Preferably, the fixed end of the electric push rod is connected to a base, and the base is connected to the centrifuge. Fixing the electric push rod with the base enhances its stability, ensuring a smooth and reliable adjustment process; it also facilitates the installation and maintenance of the electric push rod, improving the overall reliability of the system.

[0014] Preferably, the centrifuge outlet end is provided with a glass viewing cup, and the camera is disposed outside the glass viewing cup. The glass viewing cup effectively isolates the internal and external environments of the equipment, protecting the camera from contamination; the camera can clearly observe the state of the grease at the outlet end through the glass viewing cup, ensuring the accuracy and real-time nature of the monitoring image.

[0015] Preferably, the control component includes: a controller and a display screen; the camera is connected to the display screen to transmit the captured images to the display screen; the electric push rod is connected to the controller. The display screen displays the images captured by the camera in real time, facilitating remote observation of the grease status by the operator; the controller precisely controls the movement of the electric push rod, achieving precise adjustment and improving adjustment accuracy and efficiency.

[0016] Preferably, the control component further includes a remote controller, which transmits signal commands to the controller. The remote controller enables remote wireless control, allowing operators to perform adjustments in a safe and comfortable environment; this improves operational convenience and flexibility, and further reduces labor intensity and safety risks.

[0017] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a remote adjustment system for a three-phase centrifugal centrifugal pump, the beneficial effects of which are:

[0018] (1) Operators do not need to enter the equipment room, thus avoiding the impact of unpleasant environments such as odors and noise on their physical and mental health;

[0019] (2) Remote adjustment replaces manual adjustment, significantly shortening adjustment time, reducing labor intensity, and improving production efficiency;

[0020] (3) Monitor the grease status in real time and adjust the centrifugal pump in a timely manner to ensure stable grease separation effect and improve product quality; the remote control is wireless and the operation is flexible and convenient. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model discloses a remote adjustment system for a three-phase centrifugal centrifugal pump, including:

[0029] Centrifuge 1, with a centrifugal pump 2 connected to the inlet end of centrifuge 1;

[0030] Electric push rod 3, the fixed end of electric push rod 3 is connected to centrifuge 1, and the moving end is hinged to the adjusting rod 4 of centrifugal pump 2. The extension and retraction of electric push rod 3 will drive the adjusting rod 4 to rotate.

[0031] A camera is installed at the liquid outlet of centrifuge 1;

[0032] The control component, camera, and electric push rod 3 are all connected to the control component. The image captured by the camera is transmitted to the control component, which then controls the electric push rod 3 to perform corresponding actions. The control component allows remote control of the electric push rod 3 to rotate the adjusting rod 4, thereby adjusting the thickness of the liquid ring inside the centrifuge 1. This avoids manual entry into the operating room and also increases the adjustment speed.

[0033] In one embodiment, the fixed end of the electric push rod 3 is connected to a base 5, and the base 5 is connected to the centrifuge 1. The base 5 facilitates the fixing of the electric push rod 3. The hinged end of the electric push rod 3 and the adjusting rod 4 can be provided with a connector, and the hinge between the electric push rod 3 and the adjusting rod 4 is realized through the connector and the pin.

[0034] In one embodiment, a glass sight glass 6 is provided at the outlet of the centrifuge 1, and a camera is located outside the glass sight glass 6. The camera can monitor the quality of the oil flowing out of the centrifuge 1 in real time through the glass sight glass 6, and determine whether it is necessary to adjust the adjusting rod 4 of the centrifugal pump 2 based on the monitoring results.

[0035] In one embodiment, the control components include: a controller and a display screen; a camera connected to the display screen to transmit captured images to the display screen; and an electric push rod 3 connected to the controller. The display screen is located outside the equipment operating room and can remotely monitor the grease levels in the three-phase centrifuge.

[0036] In one embodiment, the control component further includes a remote controller, which sends signal commands to the controller. The remote controller can send signal commands, which are then received and processed by the controller, and a pulse signal is sent to the driver of the electric push rod 3. The driver then controls the electric push rod 3 to move, thereby controlling the rotation of the adjusting rod 4.

[0037] The thickness of the heavy and light phase liquid rings can be altered by adjusting the diameter of the centripetal pump. A larger diameter results in a thinner heavy phase liquid ring, an increased light phase liquid ring, a higher proportion of light phase in the heavy phase, and a lower proportion of heavy phase in the light phase. Conversely, a smaller diameter results in a thicker heavy phase liquid ring, a thinner light phase liquid ring, a lower proportion of light phase in the heavy phase, and a higher proportion of heavy phase in the light phase. In practical applications, the appropriate diameter of the centripetal pump should be determined based on the requirements for the separated light and heavy phases.

[0038] The traditional method for adjusting the diameter of a centrifugal pump is as follows: Hold the centrifugal pump adjusting rod 4, loosen the locking screw 7, use the adjusting rod 4 to adjust the centrifugal pump 2 to the desired value, and then tighten the locking screw 7. Currently, however, the adjusting rod 4 can be rotated by pushing the electric push rod 3, thereby adjusting the diameter of the centrifugal pump 2 and consequently the thickness of the liquid ring in the centrifuge 1. How the inner diameter of the centrifugal pump 2 is changed and how the thickness of the liquid ring in the centrifuge 1 is adjusted are functions already present in the existing centrifugal pump 2 and centrifuge 1, and their specific structures are the same as those of the existing centrifugal pump 2 and centrifuge 1.

[0039] Working principle:

[0040] The grease status at the outlet of centrifuge 1 is monitored in real time by a camera. The camera's image is transmitted to a display screen, where the operator observes the grease status. When adjustment is needed, the operator issues a command via remote control. Upon receiving the command, the controller activates the electric push rod 3, which extends and retracts, causing the adjusting rod 4 of the centrifugal pump 2 to rotate. This changes the diameter of the centrifugal pump 2 and adjusts the thickness of the liquid ring inside centrifuge 1. The entire adjustment process can be completed without manual intervention in the equipment room, achieving safe, efficient, and precise remote adjustment.
