Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of feed production and processing, and specifically relates to a countercurrent cooler. Background Art
[0002] During the feed production and processing process, feed pellets often have high temperature and humidity after processing, which not only affects the storage stability of the feed, but may also lead to a decline in feed quality.
[0003] The utility model with announcement number CN218722616U discloses a countercurrent cooler for feed production and processing, including a frame and a cooling bin and a collecting hopper mounted on the frame; a feed port and a negative pressure air suction port are provided above the cooling bin, a blower is installed in the feed port, a slanting drop table is provided at the bottom of the cooling bin, a stirrer for material mixing is installed above the drop table, the collecting hopper is located below the cooling bin, and air enters through gaps around the upper end face of the collecting hopper to naturally form an air inlet. The material cooled by the upper cooling bin falls directly into the collecting hopper from the drop table. This device adopts an upper feeding and upper suction structure, so that the negative pressure air cools the material from bottom to top in a countercurrent manner during the natural falling process of the material. The feed is more evenly distributed in the material layer of the drop table in combination with the mixing and mixing component. The suction volume can be adjusted according to the requirements of the cooled material. The entire cooling process is highly efficient, which can effectively reduce the feed powdering rate, improve the product yield, and save cooling time.
[0004] However, the above patent still has the following problems: during the feed cooling process, as the temperature drops, the moisture on the surface of the feed will tend to condense and drip. If the bottom of the cooler lacks an effective drainage design or the drainage is not smooth, the moisture will accumulate at the bottom of the device, which not only increases the difficulty of cleaning, but may also be reabsorbed by the feed through air circulation or equipment vibration, resulting in uneven moisture content in the cooled feed, affecting storage stability and product quality. During the falling process of feed particles in the cooling bin, due to the action of gravity and the friction between the particles, they are prone to sticking to and squeezing each other, especially in the drop table area. The close contact state will hinder air circulation, making it difficult for moisture and heat on the close contact surface to be effectively dissipated, resulting in uneven cooling. Under long-term close contact and high humidity, some feed may form lumps due to increased adhesion, making the device inconvenient to use.
[0005] In view of this, the present utility model is proposed. Utility Model Content

The guide chute plate 28 is disposed below the vibrating screen plate 26. The vibrating screen plate 26 has a screening plate formed therein, and the guide chute plate 28 has a guide chute formed therein. When the vibration motor 27 is activated, the vibrating screen plate 26 vibrates to screen the feed, causing the vibrating screen plate 26 to move back and forth between the two sets of second fixed plates 24.

The feed screened by the vibrating screen plate 26 and the guide chute plate 28 is collected through the discharge hopper 29. The drain valve is opened to discharge the screened water through the drain pipe 32.
[0035] According to the above conclusions, through the structure of the second fixed plate 24, the damping spring rod 25, the vibrating screen plate 26, the vibrating motor 27, the guide trough plate 28, the discharge hopper 29, the sealing plate 30 and the drain pipe 32, the purpose of vibrating and screening the feed is achieved, the feed and the water formed by cooling are separated, the cooling effect of the feed is improved, the collected water is discharged in advance, and the cooling efficiency of the feed is improved.
[0036] Example 2: Based on Example 1, the specific example is as follows Figure 1 、 Figure 2 and Figure 3 As shown, a servo motor 12 is fixedly mounted on the top of the processing tank 11. A first rotating shaft 13 is rotatably mounted on the inner top of the processing tank 11. A fan 14 is fixedly mounted on the outer wall of the first rotating shaft 13. The output shaft of the servo motor 12 is fixedly connected to one end of the first rotating shaft 13 via a coupling. When the servo motor 12 is turned on, it rotates the first rotating shaft 13, which in turn rotates the fan 14 and the second rotating shaft 15.
[0037] Specific as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a second rotating shaft 15 is fixedly mounted on the other end of the first rotating shaft 13. A fixed sleeve 16 is fixedly mounted on the outer wall of the second rotating shaft 15. Two sets of stirring rods 17 are fixedly mounted on the outer wall of the fixed sleeve 16. Fixed sleeves are fixedly mounted inside the vibrating screen plate 26 and the material guide chute plate 28. The stirring rods 17 are installed in the fixed sleeves inside the vibrating screen plate 26 and the material guide chute plate 28. The fixed sleeve 16 is driven to rotate, and the stirring rods 17 stir the feed to fully cool the feed surface.
[0038] According to the above conclusions, the structure of the processing tank 11, the servo motor 12, the first rotating shaft 13, the fan 14, the second rotating shaft 15, the fixed sleeve 16, the stirring rod 17, the vibrating screen plate 26 and the material guide trough plate 28 can achieve the purpose of stirring the feed and outputting the airflow, so that the surface of the feed is fully cooled, the cooling area of the feed is increased, and the cooling rate of the feed is improved.
[0039] Example 3: Based on Example 1 and Example 2, the specific example is as follows Figure 1 、 Figure 2 and Figure 3 As shown, a hole is formed on one side of the outer wall of the processing tank 11, into which an air outlet pipe 18 is fixedly mounted. An air pump 19 is provided at the top of the air outlet pipe 18, and a dustproof screen is provided at the output end of the air outlet pipe 18. When the air pump 19 is activated, the air flow inside the device is discharged through the air outlet pipe 18.
[0040] Specific as Figure 1 、 Figure 4 and Figure 6 As shown, a set of first fixing plates 21 are fixedly mounted on the inner walls of both sides of the processing tank 11. Heat dissipation fins 22 are snap-fitted to the top of the first fixing plates 21. A discharge port 31 is fixedly mounted on the bottom of the sealing plate 30. An electrically controlled discharge valve is installed on the outer wall of the discharge port 31. The heat dissipation fins 22 absorb heat from the feed, improving the feed cooling efficiency. The electrically controlled discharge valve is activated to discharge the screened feed at the bottom of the discharge hopper 29 through the discharge port 31.
[0041] In summary, through the structure of the air outlet pipe 18, the vacuum pump 19, the first fixed plate 21, the heat dissipation fins 22, the discharge hopper 29, the sealing plate 30 and the discharge port 31, the purpose of rapid cooling of the feed and auxiliary discharge is achieved, the flexibility of the device is improved, the processing efficiency of feed cooling is improved, and the user experience of the device is optimized.
[0042] Working principle: open the movable baffle 20, put the feed into the processing tank 11, start the vibration motor 27, drive the vibration screen plate 26 to vibrate, and the vibration screen plate 26 moves back and forth between the two sets of second fixed plates 24 to screen the feed. During the screening process, the moisture and fine particles in the feed fall into the guide trough plate 28 below through the screening plate, and flow along the guide trough to the discharge hopper 29. The screened feed continues to flow downward, while the moisture accumulates in the discharge hopper 29. Open the drain valve and discharge the screened water through the drain pipe 32. The servo motor 12 starts and drives the first rotating shaft 13 to rotate. The first rotating shaft 13 not only drives the fan 14 to rotate, but also drives the fixed sleeve 16 and the stirring rod 17 to rotate through the second rotating shaft 15. The rotation of the fan 14 generates airflow, which accelerates the flow of air inside the processing tank 11 and helps to cool the feed. The rotation of the stirring rod 17 continuously stirs the feed, so that the surface of the feed is fully exposed to the flowing air flow, further improving the cooling efficiency. The heat dissipation fins 22 on the inner walls on both sides of the processing tank 11 also absorb and dissipate the heat from the feed, further promoting the cooling of the feed. When the feed is cooled and screened, the electronically controlled discharge valve can be started to output the screened feed at the bottom of the discharge hopper 29 through the discharge port 31. The air pump 19 is started to extract the air flow inside the device through the air outlet pipe 18 to maintain air circulation inside the processing tank 11, which helps to further reduce the temperature of the feed and reduce moisture accumulation.
