Description

Technical Field

[0002] Counterflow coolers are a common type of heat exchange equipment. Their main principle is to exchange heat through fluid flow. In this type of equipment, the flow directions of the cooling medium and the cooled medium are opposite, which can improve the heat exchange efficiency because the temperature difference between the cooling medium and the cooled medium is always kept large, thereby improving the heat transfer effect.

[0003] A search revealed Chinese patent publication number CN202842297U, which discloses a flap-type counter-flow cooler for granular material processing. This cooler addresses the problems of high granular material breakage rate, high energy consumption, and easy cross-contamination inherent in existing counter-flow coolers. The invention includes a frame, a hopper, an airlock on top of the hopper, a conical material dispensing device below the airlock, an air outlet on one side of the top of the hopper, a hopper at the bottom of the hopper, and a cooling air duct. A crank-connecting rod type discharge mechanism is provided at the interface between the hopper and the hopper. This discharge mechanism is hinged to a transmission cylinder, which is fixedly mounted on the frame below the hopper.

[0004] Although the aforementioned patents have solved the problem of cooling different types of pelleted feed with different moisture contents, the uneven cooling of feed in the bucket due to the dense stacking during feed cooling still affects the cooling effect and results in a decrease in feed yield and quality. Therefore, a flip-plate counter-flow cooler is proposed to solve the above problems. Utility Model Content

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this utility model, the feed is evenly fed into the interior of the outer shell by the grooved roller. At the same time, the double-head motor is started, which makes the feed plate rotate and evenly guide the dropped feed into the interior of the outer shell. Then, through the double-head motor drive and multiple belt groups, multiple stirring plates rotate synchronously to stir the feed inside the outer shell and prevent the feed from piling up, thereby preventing the feed in the bucket from being cooled unevenly and improving the cooling effect of the feed.

[0024] 2. In this utility model, after the cylinder is started, it drives the telescopic column to push the sliding plate to move laterally. By utilizing the hole misalignment mechanism that precisely matches the sliding plate and the perforated plate, the holes of the two plates form a dynamic opening and closing control, which allows the cooled feed to instantly break away from the piled state and slide into the hopper accurately by gravity, thereby realizing the graded discharge of feed with different particle sizes and significantly improving the continuity of production.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example: Flip-plate counter-flow cooler, see reference Figures 2 to 4The system includes a support frame 1, which serves as the basic support structure for the entire cooler, bearing the weight of the outer shell 2 and all internal components. This ensures the stability and robustness of the entire device, allowing it to operate smoothly during operation. The outer shell 2 is fixedly connected to the inside of the support frame 1. The outer shell 2 provides a relatively enclosed environment for the various components inside the cooler, protecting the internal structure from external interference and contamination. It also helps maintain the temperature and airflow distribution inside the cooler, ensuring the smooth progress of the cooling process. A uniform feeding mechanism 3 is fixedly connected to the top of the outer shell 2. The uniform feeding mechanism 3 ensures that the feed enters the cooler evenly, preventing feed accumulation or uneven distribution, thereby improving cooling efficiency and the uniformity of the cooling effect. The uniform feeding mechanism 3 includes a feed hopper 31, located at the top of the outer shell 2, for... The feed hopper 31, which receives feed from the outside, is typically funnel-shaped, wider at the top and narrower at the bottom, to facilitate the smooth flow of feed. The bottom of the feed hopper 31 is fixedly connected to the top of the outer shell 2. A feeding assembly 32 is fixedly connected to the outside of the feed hopper 31. The feeding assembly 32 includes a motor a321, which is installed outside the feed hopper 31 to provide power to the feeding assembly. The motor a321 is fixedly connected to the outside of the feed hopper 31. A rotating shaft a322 is fixedly connected to the drive end of the motor a321. A grooved roller 323 is fixedly connected to the outside of the rotating shaft a322. The grooved roller 323 has grooves on its surface, which can divide the feed into small portions. As the grooved roller 323 rotates, the feed is evenly moved and gradually falls, thereby achieving uniform distribution of feed. The grooved roller 323 is rotatably connected to the inside of the feed hopper 31.

[0033] Specifically, the externally supplied feed first enters the feed hopper 31 located at the top of the outer shell 2. The funnel-shaped feed hopper 31 guides the feed downward. The motor a321 installed outside the feed hopper 31 starts, and its drive end drives the rotating shaft a322 to rotate, which in turn causes the grooved roller 323 fixedly connected to the rotating shaft a322 to rotate. The grooves on the surface of the grooved roller 323 divide the feed into small portions. As the grooved roller 323 rotates, the feed is evenly stirred and gradually falls, entering the interior of the outer shell 2 evenly from the bottom of the feed hopper 31. Inside the outer shell 2, the feed falls onto the flip plate 4. The flip plate 4 flips according to a certain pattern, causing the feed to move downward layer by layer. At the same time, cooling air enters from the air inlet 5 at the bottom of the outer shell 2 and flows from bottom to top, forming a countercurrent with the feed moving from top to bottom, exchanging heat and removing the heat from the feed. The cooled feed is finally discharged from the discharge port 7 at the bottom of the outer shell 2, while the hot air that has absorbed heat is discharged from the air outlet 6 at the top of the outer shell 2, completing the entire cooling process.

[0034] Two support columns 33 are fixedly connected inside the outer casing 2. These columns support and fix the protective casing 34 inside the outer casing 2, providing a stable mounting position for the protective casing 34 and its internal drive assembly 35. This ensures that the drive assembly will not be displaced or damaged due to vibration or external forces during operation. The protective casing 34 is fixedly connected inside the support columns 33. The protective casing 34 protects the drive assembly 35 from external environmental influences such as dust, impurities, and moisture. It also helps to isolate the heat and noise generated by the drive assembly, preventing adverse effects on surrounding components and operators. The drive assembly 35 is fixedly connected inside the protective casing 34, providing power to the feed plate 36 and the connecting plate 37 via a double-headed... The rotation drive of motor 351 drives the feed plate 36 and connecting plate 37 to move, thereby guiding the feed and moving the mixing plate 39, promoting heat exchange between the feed and the cooling medium, and improving cooling efficiency. The drive assembly 35 includes a dual-head motor 351, one of which is externally fixedly connected to the bottom of the feed plate 36, and the other is externally fixedly connected to the top of the connecting plate 37. The external of the dual-head motor 351 is fixedly connected to the inside of the protective shell 34. Two rotating shafts b352 are fixedly connected to the drive end of the dual-head motor 351, and the rotating shafts b352 are fixedly connected to the drive end of the dual-head motor 351 to transmit the power of the motor to the feed plate 36 and the connecting plate 37.

[0035] Specifically, after the external feed enters through the feed hopper 31, the grooved roller 323, driven by the motor a321, evenly distributes the feed into the interior of the outer shell 2. At this time, the drive assembly 35 located inside the protective shell 34 is activated. The dual-head motor 351 drives the feed guide plate 36 and the connecting plate 37 respectively through the rotating shafts b352 at both ends. The feed guide plate 36 receives the feed falling from the grooved roller 323 and guides it to the flip plate 4. The connecting plate 37 drives the stirring plate 39 to agitate the feed, making the feed more evenly distributed on the flip plate 4. The flip plate 4 flips according to a set pattern. As the feed moves downwards layer by layer, cooling air flows upwards from the bottom air inlet 5 of the outer shell 2, making full contact with the feed for heat exchange. The protective shell 34 fixed by the support column 33 provides a stable operating environment for the drive assembly 35, ensuring that the dual-head motor 351 continuously transmits power through the rotating shaft b352, keeping the feed plate 36 and the connecting plate 37 in motion, enhancing the heat exchange efficiency between the feed and the cooling air. Finally, the cooled feed is discharged from the bottom outlet 7 of the outer shell 2, and the hot air is discharged from the top air outlet 6, completing the entire cooling process.

[0036] A feed plate 36 is fixedly connected to the external part of the drive assembly 35. Driven by the dual-head motor 351, the feed plate 36 guides the feed to move along a certain path inside the cooler, allowing the feed to fully contact the cooling medium, thereby improving the cooling effect. The movement of the feed plate 36 also prevents the feed from accumulating or clogging inside the cooler, ensuring smooth feed flow. A connecting plate 37 is fixedly connected to the external part of the drive assembly 35. The connecting plate 37 is connected to the other drive end of the dual-head motor 351 on one hand to receive the power of the motor; on the other hand, it serves as a transmission plate. The mounting base of component 38 transmits power to the transmission component 38, thereby driving the stirring plate 39 to move and achieve the stirring and mixing of feed. The transmission component 38 is fixedly connected inside the connecting plate 37, which transmits the power received by the connecting plate 37 to the stirring plate 39. Through the rotation drive of motor b381, the rotating shaft c382 is driven to rotate, which in turn drives multiple stirring plates 39 to move through belt assembly 383, thereby achieving the stirring and mixing of feed and ensuring that the feed can be evenly contacted with the cooling medium, improving the uniformity of the cooling effect. The transmission component 38 includes motor b38. 1. Motor b381 is installed inside the connecting plate 37 to provide power to the transmission assembly 38. The speed and torque of motor b381 can be adjusted according to the movement requirements of the mixing plate 39 and the properties of the feed to control the mixing speed and force. Motor b381 is externally fixedly connected inside the connecting plate 37. A rotating shaft c382 is fixedly connected to the drive end of motor b381. The rotating shaft c382 is fixedly connected to the drive end of motor b381 to transmit the power of the motor to the belt assembly 383. A belt assembly 3 is fixedly connected to the outside of the rotating shaft c382. 83, consisting of belts, is used to transmit the power of the rotating shaft c382 to multiple stirring plates 39. The inside of the belt assembly 383 is fixedly connected to the outside of the multiple stirring plates 39, and the outside of the rotating shaft c382 is fixedly connected to the outside of one of the stirring plates 39. Multiple stirring plates 39 are rotatably connected to the bottom of the connecting plate 37. Driven by the transmission assembly 38, the stirring plates 39 can stir and mix the feed, so that the feed can be evenly distributed inside the cooler and fully contact the cooling medium, thereby improving the cooling efficiency and the uniformity of the cooling effect.

[0037] Specifically, external feed enters through the funnel-shaped feed hopper 31. Motor a321 drives the grooved roller 323 to evenly distribute the feed as it falls. At the same time, the dual-head motor 351 inside the protective shell 34 starts and drives the feed guide plate 36 through the rotating shaft b352, guiding the feed to move along a specific path. On the other side, the dual-head motor 351 transmits power to the transmission component 38 through the connecting plate 37. Motor b381 drives the rotating shaft c382, which drives multiple stirring plates 39 to rotate through the belt group 383. Under the guidance of the feed guide plate 36, the feed is mixed with the stirring plates 39 and evenly distributed on the flip plate 4. The flip plate 4 flips, causing the feed to fall layer by layer. Cooling air flows upward from the air inlet 5 at the bottom of the shell 2, fully contacting the feed for heat exchange. Finally, the cooled feed is discharged from the discharge port 7, and the hot air is discharged from the top air outlet 6.

[0038] Reference Figure 1 and Figure 5 A feeding mechanism 4 is fixedly connected to the lower interior of the outer casing 2. The feeding mechanism 4 includes a perforated plate 41. The size and distribution of the perforations are designed according to the nature of the feed and the feeding requirements to achieve feed diversion and control. The perforated plate 41 is fixedly connected to the lower interior of the outer casing 2. A feeding hopper 42 is fixedly connected to the outside of the perforated plate 41. The feeding hopper 42 is located below the perforated plate 41 and is used to receive the feed discharged from the perforated plate 41 and guide it to subsequent conveying equipment or storage devices. A sliding plate 44 is slidably connected inside the feeding hopper 42. It can slide up and down inside the feeding hopper 42 by the drive of the pushing component 43. This controls the feeding speed and flow rate of the feed. A push assembly 43 is fixedly connected to one side of the perforated plate 41. The push assembly 43 includes a cylinder 431, which is installed inside the perforated plate 41 to provide power to the sliding plate 44. The cylinder 431 is fixedly connected to the inside of the perforated plate 41. A telescopic column 432 is fixedly connected to the drive end of the cylinder 431. The telescopic column 432 is fixedly connected to the drive end of the cylinder 431 to transmit the power of the cylinder to the sliding plate 44. The telescopic column 432 is fixedly connected to the outside of the sliding plate 44. Through the telescopic movement of the cylinder, the sliding plate 44 is driven to slide up and down in the feeding hopper 42, thereby realizing the control of the feeding speed and flow rate of the feed.

[0039] Specifically, external feed enters through the feed hopper 31, and the grooved roller 323 is driven by the motor a321 to evenly feed the feed into the outer shell 2. At this time, the dual-head motor 351 of the drive assembly 35 drives the feed guide plate 36 to guide the feed movement. At the same time, the feed is stirred and mixed by the stirring plate 39 driven by the connecting plate 37 and the transmission assembly 38. The feed falls layer by layer on the flip plate 4 and fully exchanges heat with the cooling air flowing upward from the air inlet 5 at the bottom of the outer shell 2. The cooled feed falls onto the perforated plate 41 and enters the feed hopper 42 after being diverted through its holes. The cylinder 431 in the perforated plate 41 is activated, and the sliding plate 44 is pushed up and down in the feed hopper 42 by the telescopic column 432 to control the feed feeding speed and flow rate. Finally, the cooled feed is guided to the subsequent conveying equipment or storage device, and the hot air is discharged from the air outlet 6 at the top of the outer shell 2.

[0040] The implementation principle of this application embodiment is as follows: First, the feed is poured into the inside of the feed hopper 31. The motor a321 is started to drive the grooved roller 323 to rotate. Because the grooved roller 323 has multiple grooves on its surface, the feed passes through evenly into the inside of the outer shell 2. At the same time, the double-headed motor 351 inside the protective shell 34 is started to drive the rotating shaft b352 to rotate and drive the feed plate 36 to rotate. The feed plate 36 rotates and drives the falling feed to rotate and evenly scatter inside the outer shell 2. Another rotating shaft b352 drives the connecting plate 37 to rotate. The inside of the connecting plate 37 is driven by the starting motor b381 to drive the rotating shaft c382 to rotate. Then, through multiple belt sets 383, multiple stirring plates 39 rotate synchronously to stir the feed inside the outer shell 2 and prevent the feed from accumulating.

[0041] Inside the outer shell 2, the cooled feed accumulates on the perforated plate 41. The cylinder 431 is activated to drive the telescopic column 432, which in turn pushes the sliding plate 44 to move. Since the surface of the sliding plate 44 has the same holes as the perforated plate 41, the sliding plate 44 is pushed so that the holes on its surface are staggered with the holes on the surface of the perforated plate 41, allowing the feed to fall through the holes of the perforated plate 41 into the feed hopper 42, thus ensuring accurate and rapid feed discharge.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
