DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Reference Figure 1 、 Figure 3 and Figure 4 The present invention provides an embodiment of a constant temperature oil storage and weighing device, comprising a base 1, which is the main support structure of the entire weighing device and ensures the stability of the weighing device during operation. A weighing platform 2 is fixedly connected to the middle side of the top of the base 1, and a weighing bucket 3 is installed on the top of the weighing platform 2. The oil injected into the weighing bucket 3 is weighed by the weighing platform 2 to obtain an accurate weight value of the oil. The shell of the weighing bucket 3 is equipped with an electric heating wire structure to ensure that the temperature of the weighing bucket 3 is always maintained within a constant range, thereby preventing the temperature of the oil to be weighed from fluctuating. Brackets 4 are fixedly connected to both sides of the top of the base 1, and a feed bucket 5 is fixedly connected between the two brackets 4. A bellows 6 is fixedly connected between the feed bucket 5 and the weighing bucket 3. The brackets 4 support the upper half of the weighing device structure, and the bellows 6 connects the feed bucket 5 and the weighing bucket 3, further ensuring that the weight of the accessories on the device does not affect the weighing bucket 3, thereby preventing the weighing platform 2 from deviating during weighing. Furthermore, when the upper part of the device is working, the vibration generated cannot be transmitted to the weighing bucket 3, thereby further ensuring the stability of the weighing device and the accuracy of weighing.
[0035] Reference Figure 1 、 Figure 3 、 Figure 4 and Figure 5 A conveying assembly for conveying oil is installed on the top edge of the base 1. A filter cartridge 8 is fixedly connected to the inside of the feed barrel 5. An oil inlet 9 is fixedly connected to the bottom of the filter cartridge 8. A screw shaft 10 is rotatably connected to the inside of the filter cartridge 8. A motor 11 is fixedly connected to the top of the filter cartridge 8. The top of the screw shaft 10 and the output end of the motor 11 are fixedly connected. The oil is injected into the device through the oil inlet 9 for weighing. During the process, the oil will be guided directly into the filter cartridge 8 through the oil inlet 9. At this time, the filter cartridge 8 will filter the oil entering it. At the same time, the motor 11 starts to drive the screw shaft 10 to rotate, and the impurities and residues filtered out of the filter cartridge 8 are conveyed upward, thereby achieving the separation of the residue inside the oil in the first time without affecting the progress of the weighing. The bottom end of the screw shaft 10 passes through the filter cartridge 8 and is fixedly connected to a bevel gear 12. The bottom of the feed barrel 5 is fixedly connected to a fixing frame 13. The middle of the fixing frame 13 is rotatably connected to a stirring shaft 14. The top of the stirring shaft 14 is fixedly connected to the bevel gear 12. The two bevel gears 12 are meshed with each other. A plurality of scrapers 15 are fixedly connected to the outside of the stirring shaft 14. As the screw shaft 10 rotates, the two bevel gears 12 cooperate to drive the stirring shaft 14 to rotate, which in turn causes the scrapers 15 to rotate and scrape off the oil adhering to the inner wall of the feed barrel 5 and remix it with the oil inside the feed barrel 5. No oil will remain inside the device, further ensuring that the weight of the oil entering the storage device is the same as when it was weighed, thereby improving the device's weighing accuracy.
[0036] Reference Figure 2-Figure 5 An isolation cover 16 is fixedly connected between the bottom of the filter cartridge 8 and the top of the fixed frame 13, and the bevel gear 12 is located inside the isolation cover 16. The isolation cover 16 can prevent the oil from entering between the two bevel gears 12, and can also isolate the bevel gears 12 to prevent the debris generated by the friction of the bevel gears 12 from being discharged into the oil during operation. The outer side of the oil inlet 9 passes through the inside of the feed barrel 5, so that the oil entering from the inside of the oil inlet 9 will be directly transported to the inside of the filter cartridge 8 for separation of impurities and residues. A collection frame 17 is installed on the side of the filter cartridge 8 away from the oil inlet 9, so that the spiral shaft 10 will directly discharge the transported impurities and residues into the collection frame 17 for collection, waiting for subsequent unified processing. The outer wall of the scraper 15 abuts against the inner wall of the weighing barrel 3, so that the scraper 15 can scrape off the oil attached to the weighing barrel 3 for reuse when it moves. The two ends of the fixing frame 13 are fixedly connected between the two brackets 4, which makes the fixing frame 13 more stable and ensures the stable rotation of the stirring shaft 14 without affecting the weighing barrel 3. The outer wall of the screw shaft 10 abuts against the inner wall of the filter cartridge 8, so that when the screw shaft 10 rotates, it scrapes impurities and residues on the inner wall of the filter cartridge 8 and transports them upward along the interior of the filter cartridge 8.
[0037] Reference Figure 1 、 Figure 2 and Figure 6The conveying assembly includes a conveying pump 7, the bottom of which is fixedly connected to the top edge of the base 1, and a pipe is fixedly connected between the input end of the conveying pump 7 and the inside of the weighing barrel 3. When the oil inside the weighing barrel 3 is stored, the conveying pump 7 is started to extract the oil inside the weighing barrel 3, and at the same time, the oil is transported to the storage device to wait for use. A measuring tube 18 is fixedly connected to the outer wall of the weighing barrel 3, a cap 19 is threadedly connected to the top of the measuring tube 18, a T-shaped rod 20 is slidably connected to the middle of the cap 19, a float 21 is fixedly connected to the bottom of the T-shaped rod 20, electrodes 22 are fixedly connected to both sides of the top of the T-shaped rod 20, an isolation shell 23 is fixedly connected to the top of the cap 19, electrodes 22 are fixedly connected to both sides of the inner top wall of the isolation shell 23, and an indicator light 24 is fixedly connected to the top of the isolation shell 23. The upward movement of the oil level will contact the float 21, and under the action of buoyancy, the float 21, the T-bar 20 and the electrode 22 on its top will be lifted up, so that the upper and lower sets of electrodes 22 are directly and tightly contacted together. At this time, a closed circuit is formed between the left electrode 22-indicator light 24-right electrode 22. With the support of the external power supply, the closed circuit is energized, and then the indicator light 24 is turned on and a light alarm is issued to remind the oil filling personnel that the number of liters of oil weighed inside the device is too much. The electrode 22 is set inside the isolation shell 23 to ensure that dust will not adhere to the surface of the electrode 22, and then ensure the stability of the current flow. The two electrodes 22 on the top and the indicator light 24 are electrically connected, so that the external power supply-two electrodes 22 on the left-indicator light 24-two electrodes 22 on the right-external power supply. A closed circuit is formed, and the indicator light 24 starts to work. The outer side of the float 21 is slidably connected to the inside of the measuring tube 18, so that when the oil level inside the measuring tube 18 moves up, the float 21 can be pushed up immediately to remind the person who is injecting and weighing the oil.
[0038] Working principle: Oil is injected into the device through the oil inlet 9 for weighing. At this time, the oil enters the filter cartridge 8 for filtration. At the same time, the motor 11 starts to drive the screw shaft 10 to rotate, transporting the impurities and residue filtered out of the filter cartridge 8 upward. Finally, the impurities and residue separated from the oil are collected in the collection frame 17. The oil then passes through the filter cartridge 8 and falls into the weighing barrel 3. As the screw shaft 10 rotates, the two bevel gears 12 cooperate to drive the stirring shaft 14 to rotate, which in turn causes the scraper 15 to rotate and scrape off the oil attached to the inner wall of the feed barrel 5 and remix it with the oil inside the feed barrel 5. When the delivery pump 7 starts to extract the weighed oil from the weighing barrel 3 and inject it into the storage device, the stored oil does not contain impurities and will not affect the actual storage weight of the oil. There will be no oil residue inside the weighing device, further ensuring that the weight of the oil in the storage device is the same as the weight at the time of weighing, thereby improving the accuracy of the device's weighing.
[0039] As more and more oil is injected into the weighing barrel 3, the height of the oil level inside the measuring tube 18 will be the same as that inside the weighing barrel 3 through the principle of communicating vessels. At this time, the oil level will move up and contact the float 21, and under the action of buoyancy, the float 21, the T-bar 20 and the electrode 22 on its top will be lifted up, so that the upper and lower groups of electrodes 22 are directly and tightly contacted together. At this time, a closed circuit is formed between the left electrode 22-indicator light 24-right electrode 22. With the support of an external power supply, the closed circuit is energized, and then the indicator light 24 is turned on and a light alarm is issued, prompting the oil filling personnel that the number of liters of oil weighed inside the device is too much and is about to exceed the maximum limit of the device to weigh oil at one time.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
