Description

Technical Field

[0001] This utility model relates to the field of crude oil sedimentation devices, specifically a crude oil sedimentation device. Background Technology

[0002] Crude oil sedimentation unit is a specialized device that uses the density difference between oil and impurities to separate oil and sludge through the principle of gravity sedimentation. Its core function is to allow solid impurities, suspended solids and some colloidal impurities in crude oil to settle naturally to the sedimentation chamber at the bottom of the device under static conditions. The sludge is periodically discharged in conjunction with the sludge discharge structure, and the preliminarily purified upper clear oil is collected through the oil discharge system. Some models also integrate temperature control or auxiliary stirring devices to optimize sedimentation efficiency. It is a key device in the oil refining process for pretreatment and impurity removal to improve the efficiency of subsequent refining.

[0003] However, crude oil sedimentation devices mainly rely on manual observation through the viewing window to judge the sedimentation status during use. Although the current sedimentation process parameters have been standardized, the actual sedimentation rate is affected by the fluctuation of impurity content in batches of crude oil raw materials, differences in equipment cleaning residues, and interference from environmental temperature and humidity. Operators need to inspect every 1-2 hours and repeatedly compare the oil layering status with the naked eye, which consumes additional manpower. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a crude oil sedimentation device to solve the technical problems of traditional manual visual inspection which cannot accurately quantify the sedimentation process, fluctuations in raw material impurities and interference from the equipment environment causing the sedimentation rate to be fast or slow, and high-frequency manual comparison which is time-consuming and labor-intensive and prone to causing oil quality risks due to subjective misjudgment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a crude oil sedimentation device, comprising a sedimentation device including a sedimentation tank, a viewing port provided on one side of the sedimentation tank, and a scale provided on the viewing port, and transmission mechanisms provided on both sides of the viewing port, the transmission mechanism including two lead screw motors, lead screw seats meshing on the lead screws of the two lead screw motors, and a monitoring mechanism installed on the two lead screw seats;

[0006] The monitoring mechanism includes a mounting plate, on which first mounting bolts are screwed to both sides of the outer surface of the mounting plate, and the two first mounting bolts are screwed to the lead screw seat to fix the mounting plate to the lead screw seat;

[0007] The mounting plate has a first mounting groove in the middle of its outer surface, and second mounting grooves are provided above and below the first mounting groove. The first mounting groove has two first mounting screw holes inside. The first mounting groove is used to mount a vision inspection device. The vision inspection device has side ears on both sides, and two second mounting bolts are screwed onto the two side ears. The second mounting bolts are screwed into the two first mounting screw holes. A vision inspection probe for inspecting the visible port is provided on the back of the mounted vision inspection device.

[0008] By adopting the above technical solution, the sedimentation interface can be directly observed through the combination of sedimentation tank, visual port and scale; the dual lead screw motor and lead screw seat of the transmission mechanism drive the monitoring mechanism to lift and lower, ensuring the synchronization and stability of the movement.

[0009] Furthermore, each of the two second mounting slots is equipped with a mounting piece, and two second mounting screw holes are formed in the two second mounting slots.

[0010] By adopting the above technical solution, the addition of the second mounting slot and the second mounting screw hole provides an extended mounting position for the mounting plate, supporting the flexible addition of cleaning or auxiliary testing components.

[0011] Furthermore, two third mounting bolts are screwed onto both sides of the outer surface of the mounting plate, and the third mounting bolts are screwed into the second mounting screw holes.

[0012] By adopting the above technical solution, the screw connection structure between the third mounting bolt and the second mounting screw hole ensures that the mounting plate is firmly fixed, while simplifying the replacement process of the cleaning components and reducing maintenance costs.

[0013] Furthermore, the back of the two mounting plates is provided with wiping cotton, and the wiping cotton abuts against the viewing port.

[0014] By adopting the above technical solution, the wiping cotton on the back of the device continuously cleans the surface of the visible port during the raising and lowering of the monitoring mechanism, avoiding the interference of oil stains with visual detection accuracy and ensuring long-term monitoring reliability.

[0015] Furthermore, two supplementary lights are provided on both sides of the visual inspection probe to supplement the light source.

[0016] By adopting the above technical solution, the supplementary lights on both sides of the visual inspection probe adaptively adjust the light intensity, effectively compensating for the interference of turbid oil in the tank or insufficient external light, and ensuring clear and stable visual inspection data.

[0017] Furthermore, the sedimentation tank is provided with four support legs on the outer side of the bottom, and multiple oil injection pipes are provided on the other side of the sedimentation tank. A slag discharge port is provided in the middle of the bottom of the sedimentation tank.

[0018] By adopting the above technical solutions, the support legs enhance the overall stability of the settling tank; the distributed design of multiple oil injection pipes and slag discharge ports supports the optimization of continuous oil injection and centralized slag discharge processes, thereby improving process efficiency.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention comprises a transmission mechanism, a lead screw motor, a lead screw seat, a monitoring mechanism, a mounting plate, a first mounting bolt, a first mounting slot, a first mounting screw hole, a second mounting slot, a second mounting screw hole, a visual inspection device, and side lugs. The visual inspection probe, combined with a scale, captures the height of the sedimentation interface within the visible port in real time, transforming manual judgment into dynamic image analysis and digital indicators to quantify the stratification process. A supplementary light adjusts the illumination intensity to compensate for oil turbidity or ambient light interference. A wiping cotton pad on the back of the mounting plate moves up and down with the monitoring mechanism to clean the surface of the visible port, preventing oil contamination from affecting observation accuracy, stabilizing monitoring results, and reducing sedimentation rate fluctuations caused by impurities and environmental factors. The lead screw motor drives the monitoring mechanism to move up and down along a preset path for continuous automated monitoring, replacing high-frequency manual operation. Monitoring data is transmitted to the control system in real time, and the sedimentation endpoint is determined by an algorithm, avoiding the risk of over-sedimentation or premature slag discharge caused by human error, thus ensuring oil quality. This device combines mechanical automation and visual inspection technology to construct a closed-loop monitoring system, solving the problems of low efficiency, poor accuracy, and reliance on manual labor in traditional processes, and improving the controllability of crude oil sedimentation processes and the stability of product quality.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1:

[0028] A crude oil sedimentation device, such as Figure 1-4 As shown, the device includes a sedimentation device 1, which includes a sedimentation tank 101. A viewing port 105 is provided on one side of the sedimentation tank 101, and a scale is provided on the viewing port 105. A transmission mechanism 2 is provided on both sides of the viewing port 105. The transmission mechanism 2 includes two lead screw motors 201. Lead screw seats 202 are engaged on the lead screws of the two lead screw motors 201, and a monitoring mechanism 3 is installed on the two lead screw seats 202.

[0029] The monitoring mechanism 3 includes a mounting plate 301. First mounting bolts 302 are screwed onto both sides of the outer surface of the mounting plate 301, and the two first mounting bolts 302 are screwed onto the lead screw seat 202 to fix the mounting plate 301 to the lead screw seat 202.

[0030] A first mounting groove 303 is formed in the middle of the outer surface of the mounting plate 301. Second mounting grooves 305 are formed above and below the first mounting groove 303. Two first mounting screw holes 304 are formed inside the first mounting groove 303. The first mounting groove 303 is used to mount a vision inspection device 307. Side ears 308 are provided on both sides of the vision inspection device 307, and two second mounting bolts 309 are screwed onto the two side ears 308. The second mounting bolts 309 are screwed into the two first mounting screw holes 304. The device 307 is equipped with a visual inspection probe 312 on the back for detecting the visible port 105. The height of the sedimentation interface can be directly calibrated through the visible port 105 and the scale of the sedimentation tank 101. The two lead screw motors 201 and lead screw seats 202 synchronously drive the monitoring mechanism 3 to lift vertically, avoiding unilateral transmission deviation. The first mounting slot 303 and the first mounting screw hole 304 of the mounting plate 301 provide a standardized mounting position for the visual inspection device 307. The side ears 308 and the second mounting bolts 309 enable quick disassembly and assembly of the device, improving maintenance efficiency.

[0031] Example 2:

[0032] See Figure 3 , Figure 4 Each of the two second mounting slots 305 contains a mounting piece 310, and each of the two second mounting slots 305 contains a second mounting screw hole 306. The second mounting slots 305 and the second mounting screw holes 306 above and below the first mounting slot 303 provide extended installation space for the mounting piece 310, supporting the independent installation of cleaning or auxiliary testing components and avoiding interference between functional modules.

[0033] See Figure 1 , Figure 2 Two third mounting bolts 311 are screwed onto both sides of the outer surface of the mounting plate 310, and the third mounting bolts 311 are screwed into the second mounting screw holes 306. The screwed structure of the third mounting bolts 311 and the second mounting screw holes 306 ensures that the mounting plate 310 is firmly fixed, while simplifying the replacement process of the cleaning components and reducing maintenance costs.

[0034] See Figure 1 , Figure 4 The back of the two mounting plates 310 is provided with wiping cotton 314, and the wiping cotton 314 abuts against the viewing port 105. The wiping cotton 314 on the back of the mounting plates 310 continuously rubs the surface of the viewing port 105 when the monitoring mechanism 3 is raised and lowered, removing oil stains and ensuring the long-term observation accuracy of the visual inspection probe 312.

[0035] See Figure 3 , Figure 4The visual inspection probe 312 is equipped with two supplementary lights 313 on both sides. The two supplementary lights 313 are used to supplement the light source. The supplementary lights 313 on both sides of the visual inspection probe 312 automatically adjust the brightness according to the light transmittance of the oil to compensate for the interference of turbid liquid or external light changes, and ensure that the image data is clear and reliable.

[0036] See Figure 1 , Figure 2 The sedimentation tank 101 has four support legs 102 on the outer side of its bottom, and multiple oil injection pipes 103 on the other side of the sedimentation tank 101. A slag discharge port 104 is located in the middle of the bottom of the sedimentation tank 101. The four support legs 102 enhance the overall stability of the sedimentation tank 101. The multiple oil injection pipes 103 support continuous feeding, and the bottom slag discharge port 104 discharges slag in a concentrated manner, thus optimizing the efficiency of the process flow.

[0037] The implementation principle of this embodiment is as follows: First, by starting the transmission mechanism 2 of the sedimentation device 1, the two lead screw motors 201 on both sides are driven to run synchronously, which drives the lead screw seat 202 to move in the vertical direction, so that the monitoring mechanism 3 fixed on the lead screw seat 202 can perform vertical scanning along the height range of the viewing port 105.

[0038] Mounting plate 301 is rigidly connected to screw seat 202 by first mounting bolt 302 to ensure the operational stability of monitoring mechanism 3; visual inspection device 307 is fixed in the first mounting slot 303 of mounting plate 301 by side ear 308 and second mounting bolt 309, and its back visual inspection probe 312 continuously aligns with the scale area of ​​visible port 105 during movement to collect sedimentation interface image data in real time.

[0039] The supplementary lights 313 on both sides automatically adjust their brightness according to the light transmittance of the oil in the tank to compensate for changes in ambient light and ensure the clarity of visual detection. At the same time, the mounting plate 310 installed in the second mounting slot 305 is fixed by the third mounting bolt 311. The wiping cotton 314 on its back keeps in contact with the surface of the viewing port 105 during the lifting and lowering of the monitoring mechanism 3 to remove attached oil stains and avoid observation errors.

[0040] The collected visual data is processed and analyzed by the control system to dynamically track the changing trend of the sediment layer. When the detection finds that the oil sludge stratification is complete, it calls the manual control of the sludge discharge port 104 to perform the sludge discharge operation. The oil injection pipe 103 simultaneously replenishes crude oil raw materials, and the support leg 102 maintains the stability of the tank. The whole process achieves closed-loop management of the crude oil sedimentation process through the coordination of mechanical transmission, visual monitoring and automatic control, without relying too much on manual intervention.
