Description

Technical Field

[0001] The utility model relates to the technical field of crude oil analysis and detection equipment, in particular to a centrifuge for determining the moisture content of crude oil. Background Art

[0002] In the environment where centrifuges separate crude oil and water, the stability and adaptability of the centrifuge are crucial. However, there are some problems in the existing technology:

[0003] First, existing centrifuges lack an effective balance calibration mechanism. If the weight of the material is not evenly distributed during separation, it may cause increased vibration of the equipment, affect the separation effect, and even cause safety hazards.

[0004] Secondly, existing centrifuges can usually only use separation tubes of fixed specifications. Due to differences in crude oil concentration and physical properties, different experiments often require the use of separation tubes of different specifications. Using different centrifuges is cumbersome and increases experimental costs and time.

[0005] Therefore, there is an urgent need to design a crude oil moisture determination centrifuge that can solve the above technical problems. Utility Model Content

[0006] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a centrifuge for measuring the moisture content of crude oil to solve the problems mentioned in the background technology.

[0007] In order to achieve the above objectives, the present invention mainly provides the following technical solutions:

[0008] A centrifuge for determining the moisture content of crude oil, comprising a body and:

[0009] Balance calibration mechanism and multi-specification separation tube adaptation mechanism; wherein:

[0010] The balancing and calibration mechanism includes a chute a provided on the side wall of the rotor disk, a slider a movably installed in the chute a, an extension rod provided on the slider a, a gasket sleeved on the middle end of the extension rod, and a rotating block movably installed at the end away from the rotor disk;

[0011] The multi-specification separation tube adaptation mechanism includes a telescopic button installed in a button groove, a reset spring a is fixedly installed at the bottom of the telescopic button, sliders b are provided at both ends of the side walls of the telescopic button and a groove is opened near the side wall of the separation tube groove, a traction rope is provided at the bottom of the groove, and the other end of the traction rope is fixedly connected to a clamping rod, a reset spring b is provided on one side of the clamping rod, and a connecting rod is provided on the other side, and the other end of the connecting rod is fixedly connected to the support block.

[0012] Furthermore, it also includes a machine cover arranged at the upper part, which is movably connected to the fuselage through a hinge shaft, a parameter screen, a calibration screen and a parameter button are provided at the front of the upper end of the fuselage, a rotor slot is provided at the rear of the upper end, a power slot is provided at the lower end of the rotor slot, a motor is provided in the power slot, a rotating shaft is provided at the top of the motor, the rotating shaft passes through the power slot and the rotor slot, a cross clamp is provided at the top of the rotating shaft, a screw hole a is provided at the center of the upper end of the cross clamp, and a balance sensor is provided on the outer ring of the screw hole a.

[0013] Furthermore, a cross slot is provided at the bottom of the rotor disk, a screw hole b is provided inside the cross slot, and a screw hole c is provided at the upper end of the screw hole b and passes through the upper surface of the rotor disk.

[0014] Furthermore, separation tube grooves are evenly arranged along the circumference of the upper surface of the rotor disk, a button groove is arranged inside the corresponding separation tube groove position, a slide groove b is arranged on the upper inner side wall of the button groove, and the button groove and the separation tube groove are connected by connecting through holes a, through holes b and through holes c.

[0019] First, compared to existing centrifuges, these lack an effective balance calibration mechanism, resulting in unstable and even dangerous equipment operation when the material weight is unbalanced. To address this issue, the crude oil moisture measurement centrifuge in this utility model incorporates a balance calibration mechanism. By incorporating structures such as slides and sliders on the sidewalls of the rotor disc, the user can flexibly adjust the balance state, effectively improving the equipment's operational stability and separation efficiency while avoiding safety hazards.

The traction rope 35 connects the telescopic button 31 and the card rod 36. By stretching the traction rope 35, the user can control the card rod 36 by pressing the telescopic button 31. A reset spring b37 is provided on one side of the card rod 36. The reset spring b37 provides the rebound force of the card rod 36, so that the card rod 36 automatically returns to its initial position after completing the action. A connecting rod 38 is provided on the other side, and the other end of the connecting rod 38 is fixedly connected to the support block 39. The support block 39 is used to support the separation tube. Through the cooperation of the connecting rod 38 with the card rod 36, the telescopic button 31 and other parts, it is not only ensured that the separation tube groove 144 can adapt to separation tubes of different specifications, but also can provide stable support to prevent the separation tube from shaking during centrifugation.

[0048] like Figure 1 、 2As shown, in this embodiment, it also includes a machine cover 12 arranged at the upper part, and the machine cover 12 is movably connected to the machine body 11 through a hinge shaft 13.

The rotating shaft 1172 transmits the power of the motor 117 to the rotor disk 14. The rotating shaft 1172 passes through the power slot 116 and the rotor slot 115. A cross clamp 1173 is provided at the top of the rotating shaft 1172. The cross clamp 1173 ensures that the rotor disk 14 can be firmly connected to the rotating shaft 1172. At the same time, its cross design helps to achieve a more uniform force distribution. A screw hole a1175 is provided at the center of the upper end of the cross clamp 1173. A balance sensor 1174 is provided on the outer ring of the screw hole a1175. The balance sensor 1174 monitors the balance state of the rotor disk 14 in real time and displays it on the calibration screen 112 for adjustment before operation and observation during operation.

[0049] like Figure 3 、 4 As shown, in this embodiment, a cross slot 141 is defined at the bottom of the rotor disk 14. The combination of the cross slot 141 and the cross clamp 1173 ensures a secure connection between the rotor disk 14 and the rotating shaft 1172. A screw hole b142 is defined inside the cross slot 141. The screw hole b142 and the screw hole a1175 are connected by screws a16 to further secure the rotor disk 14 and the rotating shaft 1172. A screw hole c143 is defined at the upper end of the screw hole b142 and passes through the upper surface of the rotor disk 14. The screw hole c143 ensures a secure connection between the rotor disk 14 and the baffle 15.

[0050] like Figure 3 、 7As shown, in this embodiment, separation tube grooves 144 are evenly provided along the circumference of the upper surface of the rotor disk 14. The separation tube grooves 144 are used to accommodate separation tubes of different specifications. Their uniform distribution ensures that the equipment is uniformly stressed during the centrifugation process. A button groove 145 is provided inwardly corresponding to the separation tube groove 144. The button groove 145 is used to install the telescopic button 31, so that it can cooperate with the separation tube to achieve rapid adaptation of separation tubes of different specifications. A sliding groove b146 is provided on the upper part of the inner wall of the button groove 145. The button groove 145 and the separation tube groove 144 are penetrated by connected through holes a147, b148 and c149. Through these through holes, structures such as the traction rope 35 and the clamping rod 36 can pass smoothly, thereby realizing the coordinated work of multiple mechanisms.

[0051] like Figure 6 As shown, in this embodiment, the slider b32 is movably installed in the slide groove b146, ensuring the flexibility of operation. The card rod 36 and the return spring b37 are arranged in the through hole b148, ensuring the rebound function of the card rod 36 and also ensuring that the position of the card rod 36 is fixed. The connecting rod 38 is arranged in the through hole c149 and passes through the separation tube groove 144. The connecting rod 38 ensures the movement of the support block 39, thereby realizing the function of fixing the separation tube and adapting to separation tubes of different specifications. The traction rope 35 passes through the through hole a147 to fix the card rod 36 with the telescopic button 31, ensuring that the user can move the support block 39 by pressing the telescopic button 31.

[0052] like Figure 3 As shown, in this embodiment, a baffle 15 is provided at the upper end of the rotor disk 14. The baffle 15 is used to prevent foreign matter from entering the separation tube and also provides a certain degree of safety protection to prevent the user from accidentally contacting the rotor disk 14 during operation. A screw hole d151 is provided in the center of the baffle 15. The screw hole d151 is threadedly connected to the screw hole c143 by a screw b17, and the screw hole b142 is threadedly connected to the screw hole a1175 by a screw a16. The threaded connection between the screws and the screw holes ensures the stability of the device.

[0053] like Figure 2 As shown, in this embodiment, a lock 121 is provided at the front end of the cover 12, and a lock hole 114 is provided at the front end of the upper surface of the body 11. The lock 121 and the lock hole 114 ensure that the cover 12 can be firmly locked when the centrifuge is running, avoiding safety problems caused by accidental opening.

[0054] like Figure 9 As shown, in this embodiment, scale lines are provided on the surface of the separation tube, through which the user can directly read the volume ratio of water and crude oil after separation.

[0055] The working principle and usage process of this technical solution are as follows: during use, a separation tube of appropriate specifications is selected according to the concentration of the crude oil sample, the sample crude oil is injected into the separation tube and installed on the rotor disk 14 of the centrifuge, the telescopic button 31 is pressed, the telescopic button 31 sinks, and the traction rope 35 is pulled to cause the clamping rod 36 to retract inward, further driving the support block 39 to retract inward, so that the separation tube can be inserted, and after releasing the telescopic button 31, the support block 39 presses the separation tube under the action of the return spring a33 and the return spring b37; then, the baffle 15 is placed directly above the rotor disk 14, and the screw b17 is screwed into the screw hole d151 and the screw hole c14. 3, the balance state of the centrifuge is adjusted through the balance calibration mechanism 2, the machine cover 12 is closed, the parameters are adjusted, and after the centrifuge is started, the motor 117 drives the rotating shaft 1172 to rotate, and the rotating shaft 1172 transmits power to the rotor disk 14, so that the crude oil sample in the separation tube is rotated and separated at high speed. During the centrifugation process, due to the density difference between crude oil and water, crude oil and water will be separated into layers in order of density. After centrifugation, the user can easily read the volume ratio of crude oil and water through the scale lines on the surface of the centrifuge tube, and then accurately determine the water content in the sample. After the experiment, press the telescopic button 31 to remove the separation tube, and the parts can automatically reset.

[0056] The whole process is simple and easy, does not require too many operating steps, and the various parts of the device are compact in structure and easy to operate, making it suitable for the moisture determination of crude oil samples with different concentrations.

[0057] The present invention is further described above in conjunction with the embodiments, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
