Description

Technical Field

[0001] This utility model relates to the field of cooling equipment, and in particular to a cooler discharge device and a cooler. Background Technology

[0002] Currently, in the feed production field, coolers are key equipment, and the performance of their discharge devices directly affects feed quality and production efficiency. With the development of large-scale feed mills and the increase in pellet mill capacity, the requirements for coolers are higher, but traditional cooler discharge devices have obvious defects.

[0003] Traditional push-pull and flip-plate discharge devices, after being scaled up, suffer from manufacturing problems that make it difficult to control the discharge gap, resulting in uneven discharge and an imbalance in material distribution within the cooling box. For example, there may be more material in the middle and less around the edges, affecting the efficiency of heat exchange between the cold air and the material. Similarly, in vertical counter-flow coolers, improper adjustment of the material distribution cone or uniform feeder can lead to uneven material dispersion, resulting in excessively thick material layers in some areas of the cooling box and prolonging the cooling time.

[0004] Malfunctions in the discharge mechanism also affect cooling efficiency. For example, in sliding discharge mechanisms, issues with cylinder or limit bolt adjustments can lead to excessive or insufficient discharge volume. Excessive discharge results in a short material residence time in the cooling chamber, making it difficult to lower the material temperature to the standard of 3-5°C above room temperature. Furthermore, traditional discharge devices have small airflow areas and curved air paths, obstructing the counter-current flow of cooling air and material, leading to insufficient heat exchange and further reducing cooling efficiency. These problems make existing coolers insufficient to meet the demands of high-efficiency production, necessitating improvements to the structure and control methods of the discharge device.

[0005] Therefore, it is necessary to propose a new type of cooler discharge device to solve the above problems. Utility Model Content

[0006] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, the present utility model provides a cooler discharge device.

[0007] Technical solution: A cooler discharge device, comprising:

[0008] Several baffles are arranged in parallel inside the cooler. The cross-section of the baffles is configured as an inverted V shape. A rotating shaft is provided at the bottom between adjacent baffles. The bottom end of the baffle abuts against the rotating shaft. The rotating shaft is provided with a through hole. When the edge of the through hole extends beyond the lower end face of the baffle, the material is in the discharge state.

[0009] Furthermore, the rotating shaft is provided in multiple ways, and the multiple rotating shafts are arranged in parallel. One end of the multiple rotating shafts is sequentially driven and connected by a transmission mechanism. In addition, at least one driving mechanism is included, and the transmission mechanism is driven and connected to the driving mechanism.

[0010] Furthermore, the baffle includes several inverted V-shaped components stacked vertically, and the pivot is located on the underside of the bottom inverted V-shaped component.

[0011] Furthermore, the baffle plate is provided with several punched holes.

[0012] Furthermore, the cooler is also provided with several partitions, which are used to divide the material discharge bins between adjacent baffles into multiple bins.

[0013] Furthermore, the drive mechanism includes a motor and a reducer connected to the motor, and the transmission mechanism is a sprocket mechanism.

[0014] Furthermore, the perforations are arranged in a regular pattern on the baffle.

[0016] Beneficial effects: This utility model provides a cooler discharge device. By setting a rotatable shaft with through holes, the discharge operation can be started / stopped by rotating the shaft. Compared with existing solutions, the discharge speed and discharge volume can be precisely adjusted. At the same time, because an inverted V-shaped baffle is set, the material can be guided to scatter and spread flat, thereby avoiding material accumulation. This solution has a simple structure, is easy to manufacture, has high reliability, and is conducive to promotion. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0021] See Figure 1 The present invention discloses an embodiment of a cooler discharge device, comprising: a plurality of baffles 1 and a rotating shaft 2. The baffles 1 are arranged in parallel inside the cooler, and their cross-section is an inverted V-shaped structure. A rotating shaft 2 is installed at the bottom between adjacent baffles 1, and the bottom end of the baffle 1 abuts against the rotating shaft 2 to form a structure that guides the flow of material. A through hole is provided on the rotating shaft 2, and the position of the through hole is related to the rotation state of the rotating shaft 2—when the rotating shaft 2 rotates to the through hole being horizontal, the material discharge can be closed; when the rotating shaft 2 rotates to the through hole being non-horizontal, the material is in the discharge state.

[0022] In practical applications, the number of rotating shafts 2 can be set to multiple according to the specifications of the cooler, and they are arranged in parallel. One end of each rotating shaft 2 is sequentially driven and connected through a transmission mechanism 3, which is connected to the drive mechanism. The drive mechanism includes a motor 5 and a reducer 4. The power of the motor 5 is adjusted by the reducer 4 and then transmitted to each rotating shaft 2 through the transmission mechanism 3, realizing synchronous rotation control of multiple rotating shafts 2.

[0023] Furthermore, the structure of baffle 1 can be optimized, for example, by using several inverted V-shaped components stacked vertically. In this case, the rotating shaft 2 is located under the bottom inverted V-shaped component, and the multi-layer structure enhances the guiding and leveling effect on the material. The baffle 1 has several perforations, which are regularly distributed on the baffle 1 to facilitate ventilation and accelerate the cooling process. In other embodiments, the baffle 1 can also be configured as an inverted V-shaped component, and the horizontal arrangement of multiple baffles 1 divides the cooler into multiple horizontally oriented material drop bins. Preferably, the cooler also includes several partitions 7, which divide the material drop bins between adjacent baffles 1 into multiple sections.

[0024] This utility model also provides a cooler, see [link] Figure 2 As shown, the system includes a cooler housing 10, with a feed inlet 11 at the top and a hopper 12 at the bottom, with a discharge outlet at the bottom of the hopper 12. An air outlet 13 is located on one side of the upper part of the cooler housing 10 to discharge air carrying heat during the cooling process. The aforementioned cooler discharge device is installed in the middle of the interior of the cooler housing 10, forming a complete cooling system.

[0025] After the material enters the cooler box 10 through the feed inlet 11, it is first guided by the inverted V-shaped baffle 1. The inclined surface of the inverted V-shaped baffle 1 causes the material to fall to both sides, avoiding local accumulation and forming a uniform material layer in the cooling box, laying the foundation for sufficient heat exchange between the cold air and the material. After the motor 5 in the drive mechanism starts, the power is adjusted by the reducer 4 and transmitted to each rotating shaft 2 through the transmission mechanism 3, driving the rotating shaft 2 to rotate synchronously. When it is necessary to close the discharge, the drive mechanism controls the rotating shaft 2 to rotate, so that the through hole on the rotating shaft 2 is adjusted to a horizontal state. At this time, the through hole forms a blocking structure, and the material cannot fall. When it is necessary to open the discharge, the drive mechanism rotates the rotating shaft 2, so that the through hole is no longer horizontal. At this time, the gap between the rotating shaft 2 and the baffle 1 opens, and the material falls through the through hole under the action of gravity, enters the discharge hopper 12, and is discharged from the outlet. By controlling the rotation angle and speed of the rotating shaft 2, the discharge speed and discharge volume can be adjusted—the larger the rotation angle, the larger the opening area of ​​the through hole, and the discharge volume increases, and vice versa, achieving precise control of the discharge process. During the cooling process, external cold air enters from the bottom or side of the cooler housing 10, creating a counter-current flow with the material flowing downwards. The inverted V-shaped baffle 1 ensures even material distribution, allowing the cold air to penetrate the material layer effectively, carrying away heat and exiting through the air outlet 13. This uniform material layer distribution and controllable discharge speed ensure sufficient residence time for the material within the cooling chamber, reducing its temperature to the target range and preventing localized overheating due to uneven discharge, thus improving cooling efficiency and feed quality.

[0026] This discharge device guides materials through an inverted V-shaped baffle 1, solving the problem of insufficient heat exchange caused by material accumulation in traditional devices. The rotatable shaft 2 and through-hole design allow for flexible adjustment of the discharge volume, providing more precise control compared to traditional structures. Furthermore, the multi-shaft linkage design via the transmission mechanism 3 ensures consistent discharge within the large-area cooler. Combined with the drive mechanism of the motor 5 and reducer 4, it can adapt to automated control scenarios with varying production capacity requirements. The overall structure is simple, easy to manufacture, and highly reliable, facilitating its widespread application in the feed production field.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
