Description

Technical Field

[0001] The invention relates to the technical field of storage, and in particular to low-temperature resistant storage equipment for corn. Background Art

[0002] In the corn kernel production process, the key to ensuring product quality and preserving its freshness is to use a refrigeration system to refrigerate the corn kernels. Low-pressure circulating liquid storage barrels are mainly used in refrigeration and air-conditioning systems. They are key equipment in the fluorine pump liquid supply system of the fluorine refrigeration unit. Their function is to store a certain amount of low-pressure refrigerant liquid and supply it stably to the circulating pump. At the same time, they also act as a gas-liquid separator. Therefore, the fluorine low-pressure circulating liquid storage barrel plays the role of gas-liquid separation and liquid storage.

[0003] Chinese patent CN116692265A published on September 5, 2023 discloses a low-temperature resistant storage device for corn, which solves the problem that the low-pressure circulating liquid storage barrel in the prior art cannot automatically adjust and control the liquid level of the internal refrigerant, and cannot perform convenient and stable thermal insulation protection on the low-pressure circulating liquid storage barrel body. However, the low-pressure circulating liquid storage barrel cannot effectively and quickly cool the refrigerant entering the liquid storage barrel. When the refrigerant enters the interior of the liquid storage barrel from the liquid inlet, a part of the refrigerant will vaporize and increase the temperature inside the liquid storage barrel, thereby reducing the stability of the refrigerant inside the liquid storage barrel, making the liquid refrigerant easily converted into gas. Excessive gaseous refrigerant is prone to leakage in the low-pressure circulating liquid storage barrel, and the leaked ammonia can easily cause environmental pollution. Summary of the invention

DETAILED DESCRIPTION

[0017] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Example 1, please refer to Figure 1-Figure 10The present invention provides a technical solution: a low-temperature resistant storage device for corn, comprising a liquid storage barrel 1, a liquid inlet 2 and a liquid discharge port 3 are provided at the top of the liquid storage barrel 1, a servo motor 4 is installed at the top of the liquid storage barrel 1, a sewage discharge component 5 is installed at one end of the servo motor 4, a cooling component 6 is installed at one end of the servo motor 4, the cooling component 6 comprises an annular cooling bin 605 and a temperature insulating shell 611 adapted to the liquid storage barrel 1, and the bottom end of the inner wall of the annular cooling bin 605 is arc-shaped and arranged downward.

[0020] During use, when the refrigerant enters the liquid storage barrel 1 from the liquid inlet 2, a portion of the refrigerant will be vaporized and increase the temperature inside the liquid storage barrel 1, thereby reducing the stability of the refrigerant inside the liquid storage barrel 1. At this time, the servo motor 4 is started to drive the cooling component 6 to operate, converting the gaseous refrigerant inside the liquid storage barrel 1 back into liquid, while reducing the temperature inside the liquid storage barrel 1 to an appropriate range.

[0021] See also Figure 8-Figure 9 As shown in the figure, the cooling component 6 includes a connecting block 601 and an annular cooling bin 605 arranged at the top of the liquid storage barrel 1. The connecting block 601 is installed at one end of the servo motor 4. A belt 602 is connected to the outer wall of the connecting block 601. A transmission block 603 adapted to the belt 602 is arranged on the surface of the annular cooling bin 605. One end of the transmission block 603 extending into the interior of the annular cooling bin 605 is fixedly connected with a fan blade 604. A cooling fin 606 is arranged on the inner circumferential surface of the annular cooling bin 605 in a circumferential direction. An air intake port 607 is opened on the inner wall of the annular cooling bin 605 perpendicular to the direction of the fan blade 604. A drainage port 609 is opened on the inner wall of the annular cooling bin 605 at one end facing away from the air intake port 607. An insulating shell 611 is arranged on the outer wall of the liquid storage barrel 1.

[0022] When in use, the servo motor 4 is started to drive the connecting block 601 to rotate, and the transmission block 603 is driven to rotate through the belt 602, so that the fan blade 604 rotates at a high speed inside the annular cooling bin 605, so that the refrigerant gas vaporized inside the liquid storage barrel 1 is sucked into the inside of the annular cooling bin 605 through the air intake port 607, and at the same time, the air inside the cabin between the thermal insulation shell 611 and the liquid storage barrel 1 is sucked into the inside of the annular cooling bin 605 through the air intake pipe 608, so that the two gases flow inside the annular cooling bin 605, and at the same time, the refrigeration plate 606 inside the annular cooling bin 605 is started to recondense the gaseous refrigerant gas into liquid and cool the air, and then the refrigerant flows to the drain port 609 through the inclined surface inside the annular cooling bin 605 and returns to the inside of the liquid storage barrel 1, and the cooled air flows back to the inside of the cabin through the exhaust pipe 610, so that the cabin can maintain a low temperature for a long time, and isolate the external heat from entering the inside of the liquid storage barrel 1, preventing the refrigerant in the liquid storage barrel 1 from vaporizing due to excessive temperature.

[0023] See also Fig.10 As shown in the figure, a cabin is formed in the hollow space between the heat-insulating shell 611 and the liquid storage barrel 1, and an air inlet pipe 608 adapted to the air intake port 607 is provided on the surface of the cabin, and an exhaust pipe 610 adapted to the water discharge port 609 is provided on the surface of the cabin. A blocking plate 612 is fixedly connected to the surface of the liquid storage barrel 1 at a position between the air inlet pipe 608 and the exhaust pipe 610, and a plurality of guide plates 613 are fixedly connected to the surface of the liquid storage barrel 1.

[0024] When in use, the air inside the cabin can be isolated by the blocking plate 612 so that the air can only move in one direction, and the guide plate 613 can guide the flow direction of the air so that the cold air entering the cabin can flow through every corner of the outer wall of the liquid storage barrel 1, thereby ensuring the stability of the temperature of the outer wall of the liquid storage barrel 1.

[0025] See also Figure 3 As shown in the figure, the sewage discharge assembly 5 includes a position adjustment mechanism, a filtering mechanism and a scraping mechanism. The position adjustment mechanism includes a connecting shaft 504, which is arranged on the side of the sleeve 502 close to the bottom end of the liquid storage barrel 1. A reducer 501 adapted to the sleeve 502 is arranged at the top center position of the liquid storage barrel 1. The top of the connecting shaft 504 is fixedly connected to a limit pin 505, and a return spring 506 adapted to the connecting shaft 504 is arranged inside the sleeve 502. A guide groove 507 adapted to the limit pin 505 is arranged on the surface of the sleeve 502. The connecting shaft 504 is slidably matched with the guide groove 507 through the limit pin 505 and can only slide in the direction vertical to the pressing plate 508. The bottom end of the connecting shaft 504 is rotatably connected to the pressing plate 508.

[0026] When in use, start the servo motor 4 to drive the sleeve 502 to rotate counterclockwise through the reducer 501. At this time, the ratchet 509 and the pawl 510 limit the connecting shaft 504, so that the connecting shaft 504 will not rotate with the sleeve 502. Through the cooperation of the limit pin 505 and the guide groove 507, the rotation of the sleeve 502 will apply a thrust to the limit pin 505, so that the limit pin 505 slides downward along the surface of the guide groove 507, thereby pushing the connecting shaft 504 out of the sleeve 502 and pushing the pressing plate 508 into the sewage barrel 518. The reset spring 506 can provide pulling force to the extended connecting shaft 504, so that the sleeve 502 can pull the connecting shaft 504 to reset when rotating clockwise, and pull the pressing plate 508 out of the sewage barrel 518.

[0027] See also Figure 4As shown in the figure, the position adjustment mechanism also includes a ratchet 509, a pawl 510 and a spring sheet 511. The ratchet 509 is fixedly connected to the center position of the pressing plate 508, and a pawl 510 adapted to the ratchet 509 is provided on the side of the connecting shaft 504 close to the pressing plate 508, and a spring sheet 511 adapted to the pawl 510 is provided on the side of the connecting shaft 504 close to the pressing plate 508.

[0028] When in use, start the servo motor 4 and drive the sleeve 502 to rotate clockwise through the reducer 501. The sleeve 502 will apply a torque to the connecting shaft 504 through the limit pin 505. At this time, the ratchet 509 will squeeze the pawl 510 on the surface of the connecting shaft 504 to rotate on the surface of the connecting shaft 504 and squeeze the spring sheet 511. Then, the spring sheet 511 is subjected to the force to push the pawl 510 to reset, so that the sleeve 502 can drive the connecting shaft 504 to rotate on the surface of the pressing plate 508. When the sleeve 502 rotates counterclockwise, the engagement of the ratchet 509 and the pawl 510 will limit the rotation of the connecting shaft 504, so that the sleeve 502 can only drive the scraper 503 to rotate and push the connecting shaft 504 to move vertically downward.

[0029] See also Figure 4 As shown in the figure, the filtering mechanism includes a through groove 512, and the through groove 512 is arranged along the circumferential direction on the surface of the pressing plate 508. A cover plate 513 adapted to the through groove 512 is arranged on the surface of the pressing plate 508, and a telescopic spring 514 is arranged at one end of the cover plate 513. A pressing column 515 adapted to the scraping mechanism is arranged on the outer wall of the bottom end of the pressing plate 508, and a filter membrane 516 is arranged on the outer wall of the bottom end of the pressing plate 508. A filter sponge 517 is arranged on the side of the filter membrane 516 close to the scraping mechanism.

[0030] During use, after entering the interior of the sewage barrel 518, the pressing plate 508 continues to descend so that the pressing plate 508 presses the refrigerant in the sewage barrel 518. After being squeezed, the refrigerant will pass through the filter sponge 517 and the filter membrane 516 to enter the interior of the through groove 512, and lift up the cover plate 513 covering the surface of the through groove 512, so that the refrigerant passes through the through groove 512 and flows back to the interior of the liquid storage barrel 1. During this process, the sediment will be filtered by the filter sponge 517 and remain on the surface of the filter sponge 517, while the lubricating oil will remain in the filter sponge 517 after being filtered by the filter membrane 516. When the refrigerant in the sewage barrel 518 is filtered, the cover plate 513 is pushed to cover the surface of the through groove 512 again under the action of the telescopic spring 514 to prevent the refrigerant in the liquid storage barrel 1 from flowing back through the through groove 512.

[0031] See also Figure 5 , Figure 6 and Figure 7As shown in the figure, the scraping mechanism includes a sewage discharge barrel 518, and a sewage inlet 519 is opened on the outer wall of one end of the sewage discharge barrel 518 extending into the liquid storage barrel 1. The sewage inlet 519 is arranged in multiple groups along the circumferential direction on the outer circumferential surface of the sewage discharge barrel 518. A discharge plate 525 is rotatably connected to the inner wall of one end of the sewage discharge barrel 518 extending out of the surface of the liquid storage barrel 1. A rotating shaft 526 is slidably arranged on the outer circumferential surface of the discharge plate 525 along the circumferential direction. A cleaning plate 527 is rotatably connected to the surface of the rotating shaft 526, and a scraper 503 is fixedly connected to the sleeve 502 near the bottom end of the liquid storage barrel 1.

[0032] When in use, the blanking plate 525 and the cleaning plate 527 are closed so that they are on the same horizontal line, thereby blocking one end of the sewage barrel 518, so that when the scraper 503 scrapes the sediment and lubricating oil inside the liquid storage barrel 1 into the sewage barrel 518 through the sewage inlet 519, the blanking plate 525 and the cleaning plate 527 can prevent the sediment, lubricating oil and refrigerant from flowing out of the interior of the liquid storage barrel 1.

[0033] See also Figure 6 and Figure 7 As shown in the figure, the scraping mechanism also includes a slide groove 520, a groove 521 is opened on the inner wall of the slide groove 520, a torsion spring 528 adapted to the cleaning plate 527 is arranged on the surface of the rotating shaft 526, a connecting column 529 adapted to the groove 521 is arranged on the side of the cleaning plate 527 close to the inner wall of the sewage discharge barrel 518, a fixing sleeve 522 is arranged at the center position of the sewage discharge barrel 518, a spiral rod 523 adapted to the unloading plate 525 is arranged on the inner wall of the fixing sleeve 522, and a force spring 524 adapted to the spiral rod 523 is arranged on the inner wall of the fixing sleeve 522.

[0034] When in use, after the sediment and lubricating oil are filtered out, the pressing plate 508 continues to press down, so that the pressing column 515 pushes the spiral rod 523 to slide into the interior of the fixed sleeve 522 and squeeze the force spring 524. When the spiral rod 523 slides, it can drive the unloading plate 525 to rotate inside the sewage discharge barrel 518, thereby pushing the connecting column 529 to slide from the inside of the groove 521 into the inside of the slide groove 520, and lift one end of the cleaning plate 527, so that the lifting end of the cleaning plate 527 can be rotated in coordination with the rotation of the unloading plate 525. While squeezing the filter sponge 517, the sediment on the surface of the filter sponge 517 and the lubricating oil inside are scraped off and discharged from the interior of the liquid storage barrel 1 through the notch on the surface of the discharge plate 525. Then, when the pressing plate 508 rises, the force spring 524 will push the spiral rod 523 to reset, and cooperate with the rotation of the discharge plate 525 to push the connecting column 529 to move to the surface of the groove 521. Then, the torsion spring 528 pushes the cleaning plate 527 to close with the discharge plate 525 again, so that the connecting column 529 is stuck into the interior of the groove 521.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
