Description

Technical Field

[0001] This utility model relates to the field of oil production technology, and in particular to a blending device with oil quality monitoring capabilities. Background Technology

[0002] Oil blending typically involves mechanical stirring to uniformly mix oils in order to produce oils that meet specific performance requirements. The main purpose is to fully mix various raw materials in a specific ratio. During the oil blending process, the water content is a key quality indicator, as it directly affects the performance and service life of the oil.

[0003] According to patent publication number CN207745774U, an oil blending device relates to the technical field of lubricating oil processing equipment. It includes a blending tank and a circulating pump connected to the blending tank. The top of the blending tank has a base oil inlet and an additive inlet. The blending tank is equipped with a stirrer for mixing the oil, and the bottom of the blending tank has a rotary jet for blending the oil. The outlet of the circulating pump is connected to the rotary jet, and the inlet of the circulating pump is connected to the bottom of the blending tank. The oil blending device provided by this utility model has high blending efficiency and good product quality. It adopts a blending method combining a stirrer and a rotary jet. The circulating pump draws out the mixture, which is then sprayed through a 360-degree rotating rotary jet, ensuring thorough mixing without dead angles and uniform stirring. Oil blending can be completed in a very short time. The rotary jet combined with a vortex method ensures thorough mixing of the medium inside the blending tank, achieving a homogenization effect.

[0004] The above describes the oil blending equipment. Traditional blending equipment uses fixed stirring blades perpendicular to the bottom of the blending tank for blending. The stirring and blending range is limited, which can easily lead to dead corners at the bottom or top of the tank. The stirring effect is poor for high-viscosity liquids, which can easily result in insufficient flow. At the same time, the traditional stirring blades have a simple structure, which makes it difficult to adapt to different flow requirements and cannot be flexibly adjusted according to the characteristics of different oils. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems in the prior art, such as the inability of the stirring blades of the blending device to be tilted and adjusted according to the blending requirements, the limited range of stirring and blending, and the poor effect. Therefore, this invention proposes a blending device with oil quality monitoring capabilities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a blending device with oil quality monitoring, comprising a blending tank, wherein the blending tank is provided with a blending cavity and a storage cavity respectively, a sleeve is provided at the center of the blending cavity, a connecting column is fitted inside the sleeve, a rotating rod is rotatably connected to the interface on the surface of the connecting column, and stirring blades are fixed at both ends of the rotating rod, a base and a discharge plate are respectively connected between the blending cavity and the storage cavity, and an infrared detector and a receiver are respectively installed at the mounting ports on the inner wall of the blending tank and the top surface of the discharge plate, and the positions of the infrared detector and the receiver are vertically aligned.

[0007] As can be seen, in the above technical solution, by adjusting the tilt angle of the stirring blades, the vertical circulation of the liquid can be enhanced, the stirring is more uniform, the blades are adjustable and can adapt to liquids of different viscosities, densities and compositions, and achieve a more precise stirring effect. At the same time, the use of infrared light detection can monitor the moisture in the oil during the blending process.

[0008] Preferably, the slots on both sides of the sleeve surface are rectangular, and the connecting parts on both sides of the connecting post surface cooperate with the slots on the sleeve surface, and the connecting post surface fits into the inner wall of the sleeve.

[0009] As can be seen, in the above technical solution, the surface of the connecting column is in contact with the inner wall of the sleeve, and the connecting part on the surface of the connecting column is located in the groove on the surface of the sleeve. When the sleeve rotates, the connecting column and the stirring blade can be rotated together.

[0010] Preferably, a lifting plate is attached to one side of the connecting column, and a toothed groove is arrayed on one side of the lifting plate. A gear is fixed to the surface of the rotating rod, and the surface of the gear meshes with the toothed groove.

[0011] As can be seen, in the above technical solution, the lifting plate can be raised and lowered to rotate the rotating rod, and the tilt adjustment of the stirring blade can be completed by rotating the rotating rod.

[0012] Preferably, a connecting frame is fixed inside the connecting column, a lead screw is installed inside the connecting frame, and the end of the lifting plate is threadedly connected to the surface of the lead screw.

[0013] As can be seen, in the above technical solution, the rotation of the lead screw can control the lifting and lowering of the lifting plate, thereby achieving tilt control of the stirring blades.

[0014] Preferably, the chassis is fixed to the inner wall of the mixing tank, the discharge plate is in contact with the bottom surface of the chassis, and the discharge plate is movably connected to the mixing tank.

[0015] As can be seen, in the above technical solution, the mixing chamber and the storage chamber are separated by the chassis and the discharge plate. The top surface of the chassis is curved to prevent the mixed grease from being unable to be discharged downwards normally.

[0016] Preferably, the positions of the discharge ports on the chassis and the discharge tray correspond to each other, and the sizes of the discharge ports on the chassis and the discharge tray are the same.

[0017] As can be seen, in the above technical solution, when the discharge port on the discharge plate is rotated to align with the discharge port of the chassis, the product can be discharged downwards; when the two discharge ports are staggered, the product can be located in the mixing chamber.

[0018] Preferably, the top opening of the mixing tank is hinged with a top cover, and a driving structure is provided in the groove at the center of the bottom surface of the chassis.

[0019] As can be seen, in the above technical solution, the top cover can close the opening at the top of the mixing tank, which facilitates the control of the temperature inside the mixing tank. At the same time, the components in the drive structure can drive the rotation of the sleeve and the discharge plate respectively.

[0020] Beneficial effects

[0021] In this invention, the tilt angle of the stirring blades can be adjusted according to the oil blending requirements before stirring. The gear is driven to rotate by a lifting plate, thereby adjusting the tilt of the rotating rod and stirring blades. By adjusting the tilt angle of the stirring blades, the vertical circulation of the liquid can be enhanced, resulting in more uniform stirring. At the same time, the tilted blades can break the laminar flow state of the liquid, reducing the possibility of liquid stratification or sedimentation. When blending high-viscosity oils, the tilt angle of the blades can be increased to form stronger axial and radial flow and accelerate mixing. For low-viscosity liquids, a smaller tilt angle can be adjusted to avoid generating excessive eddies that would affect the blending effect. Thus, the blending blades are adjustable and can adapt to liquids of different viscosities, densities, and compositions, achieving a more precise stirring effect. Attached Figure Description

[0029] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0032] Reference Figures 1-6A blending device with oil quality monitoring includes a blending tank 1, which has a blending cavity 14 and a storage cavity 15. The blending tank 1 serves as the outer shell of the oil blending device. The internal cavity of the blending tank 1 is divided into the blending cavity 14 and the storage cavity 15. Oil enters the blending cavity 14, where additives such as preservatives and viscosity modifiers are added and stirred according to blending requirements. During the blending process, the water content in the oil can be monitored. When the water content in the oil is within a specified range after blending, the blended oil can be discharged. The mixture is stored in the storage chamber 15 or directly recycled. A top cover 11 is hinged to the top opening of the mixing tank 1. The top cover 11 can be opened freely; it can be opened when liquid enters and closed during mixing to facilitate temperature control. A sleeve 5 is located at the center of the mixing chamber 14. A connecting column 6 is fitted inside the sleeve 5. A rotating rod 61 is rotatably connected to the interface on the surface of the connecting column 6. Stirring blades 62 are fixed at both ends of the rotating rod 61. Rotating the sleeve 5 rotates the connecting column 6 along with it. The stirring blades 62 can stir and blend the oil inside the mixing chamber 14. Since the stirring blades 62 are connected to the rotating rods 61 on the surface of the connecting column 6 at both ends, the rotation of the rotating rods 61 can adjust the tilt angle of the stirring blades 62. The tilt angle of the stirring blades 62 can be freely adjusted according to the blending requirements, allowing them to be perpendicular to the ground or tilted. Increasing the tilt angle of the blades creates stronger axial and radial flow, accelerating mixing. For low-viscosity liquids, a smaller tilt angle can be adjusted to avoid generating excessive eddies that could affect the blending effect. Sleeve 5... The slots on both sides of the surface are rectangular, and the connecting parts on both sides of the connecting column 6 cooperate with the slots on the surface of the sleeve 5. The surface of the connecting column 6 is in close contact with the inner wall of the sleeve 5. To further explain, the rectangular slots on the surface of the sleeve 5 are used to engage the connecting column 6. The connecting column 6 and the inside of the sleeve 5 cooperate with each other. The connecting column 6 can be installed inside the sleeve 5 from top to bottom. Later, it is convenient for the staff to directly remove the connecting column 6 to clean or maintain the stirring blades 62 inside or on the surface. When the sleeve 5 rotates, the connecting column 6 can rotate together with the sleeve 5.

[0033] A lifting plate 63 is attached to one side of the connecting column 6. One side of the lifting plate 63 has an array of toothed grooves 64. A gear 65 is fixed to the surface of the rotating rod 61, and the surface of the gear 65 meshes with the toothed grooves 64. The lifting plate 63 inside the connecting column 6 can move vertically and linearly along its sliding position. Because the surface of the gear 65 at the center of the rotating rod 61 meshes with the toothed grooves 64 of the lifting plate 63, the rotating rod 61 can rotate and adjust when the lifting plate 63 moves vertically, thereby adjusting the tilt of the stirring blade 62. Similarly, when the lifting plate 63 moves vertically... When fixed, the rotating rod 61 cannot rotate on its own. A connecting frame 66 is fixed inside the connecting column 6. A lead screw 67 is installed inside the connecting frame 66, and the end of the lifting plate 63 is threadedly connected to the surface of the lead screw 67. The connecting column 6 includes the connecting frame 66 inside. The lead screw 67 inside the connecting frame 66 is sleeved and threadedly connected to one end of the lifting plate 63. The lead screw 67 can be driven by a motor to rotate. The rotation of the lead screw 67 can control the movement of the lifting plate 63, thereby realizing automatic lifting and automatic adjustment of the stirring blade 62. The structure is simple.

[0034] A base plate 12 and a discharge plate 13 are respectively connected between the mixing chamber 14 and the storage chamber 15. The base plate 12 is fixed to the inner wall of the mixing tank 1, and the discharge plate 13 is in contact with the bottom surface of the base plate 12 and is movably connected to the mixing tank 1. The discharge ports on the base plate 12 and the discharge plate 13 correspond to each other, and the discharge ports on the base plate 12 and the discharge plate 13 have the same size. The base plate 12 and the discharge plate 13 are located between the mixing chamber 14 and the storage chamber 15. The base plate 12 is located on the top surface of the discharge plate 13. The top surface of the base plate 12 is inclined to prevent some grease from accumulating on the base plate 12 when falling, which would prevent normal discharge. The discharge plate 13 is a disc and is in contact with the bottom surface of the base plate 12. Both the discharge plate 13 and the base plate 12 have discharge ports. When the discharge plate 13 rotates, the discharge of grease from both is facilitated. When the openings are aligned, the grease in the mixing chamber 14 flows down the inclined surface of the top surface of the chassis 12 from the discharge port to the storage chamber 15 below. Similarly, when the discharge ports of the two are staggered, the grease can be blocked in the mixing chamber 14. A drive structure 4 is provided in the groove at the center of the bottom surface of the chassis 12. It should be noted that the chassis 12 is fixed to the inner wall of the mixing tank 1, while the discharge plate 13 is rotatably connected to the inner wall of the mixing tank 1. The drive structure 4 consists of components such as a motor and a partition. The motor rotating end at the top of the drive structure 4 is connected to the sleeve 5, allowing the sleeve 5 to rotate on the top surface of the chassis 12. The motor rotating end at the bottom of the drive structure 4 is connected to the discharge plate 13, which is used to rotate the discharge plate 13 to control the discharge. The partition divides the components such as motors into sections and also serves to fix the installation.

[0035] Infrared detectors 2 and 3 are installed on the inner wall of the blending tank 1 and at the mounting openings on the top surface of the discharge tray 13, respectively. The positions of the infrared detectors 2 and 3 are vertically aligned. The infrared detector 2 connected to the inner wall of the top opening of the blending tank 1 corresponds to the position of the receiver 3 on the top surface of the discharge tray 13. The infrared detector 2 is an infrared emitter used to emit infrared light of a specific wavelength, while the receiver 3 is a photodetector used to detect the absorption intensity of infrared light by moisture. Based on the absorption of infrared light by moisture, a signal proportional to the moisture content is output. Moisture has strong absorption of infrared light of specific wavelengths, while oil has weak absorption at these wavelengths. When the infrared light source passes through the oil layer and reaches the photodetector, the moisture significantly reduces the intensity of the infrared light. The photodetector measures the intensity of the infrared light after it passes through the oil and compares it with the initial intensity emitted by the light source. The difference can be used to calculate the moisture content in the oil, thereby detecting the water content in the oil during mixing and blending. During the process, the infrared detector 2 is always aligned with the receiver 3 to monitor the water content in the oil during blending in real time, thereby determining whether heating and dehydration treatment is required after blending. If dehydration treatment is not required, the discharge plate 13 can be rotated to allow the blended oil to fall into the storage chamber 15, or it can be discharged directly from the discharge pipe connected to the bottom of the storage chamber 15. If dehydration treatment is required, the temperature inside the blending chamber 14 can be controlled directly by electric heating or other methods, and the oil inside can be dehydrated directly by stirring. It is worth noting that because the receiver 3 is connected to the top interface of the discharge plate 13, when the discharge plate 13 closes the discharge port of the base plate 12, the position of the receiver 3 corresponds to the position of the infrared detector 2. The discharge plate 13 can only be rotated and the discharge port opened when the water content in the oil is within the specified range after blending. Only then can the position of the receiver 3 be changed, without affecting the monitoring of oil quality during blending.
