Description

Technical Field

[0001] This utility model relates to the field of feed production, and in particular to a cooling device with multi-point temperature measurement. Background Technology

[0002] The feed industry is the most industrialized sector within my country's agriculture, serving as a crucial link between planting, animal husbandry, and livestock product processing. Cooling of pelleted feed is an indispensable step in the pelleting process. During feed production, the temperature of the pelleted material is very high, necessitating cooling to ensure it reaches a suitable temperature. Counter-flow coolers can cool pellets exiting the pellet mill at 70℃~90℃ to slightly above room temperature (3℃~5℃) and reduce the moisture content to a safe level (≤12.5%), facilitating the transportation, storage, and handling of the pellets.

[0003] A search of Chinese patents revealed publication number CN207721185U, a feed cooler belonging to the field of feed production and processing equipment. The aim is to provide a feed cooler with high feed cooling uniformity and high effective volume utilization. The key technical points are: a feed cooler comprising a frame and a feeder, a cooling chamber, and a collection hopper fixedly connected to the frame in sequence. The feeder is fixedly connected to a feeding tray extending into the cooling chamber. One end of the collection hopper communicates with the cooling chamber, and the other end has a discharge port. Inside the cooling chamber, from top to bottom, there is a feed spreader and a discharge mechanism located below the feed spreader. The feed spreader includes a motor fixed to the top of the cooling chamber and a rotating shaft connected to the motor output shaft via a bearing. The rotating shaft extends vertically into the cooling chamber from the top, and an inclined downward-facing feed spreader is fixedly connected to the end of the rotating shaft away from the motor. The position of the feed spreader corresponds to that of the feeder. This utility model is applicable to feed cooling processing.

[0004] Existing cooling equipment often uses a single temperature detection point, with most devices only having a temperature sensor at a single location within the cooling chamber. This only provides temperature data for a localized area and fails to comprehensively reflect the overall temperature distribution and trends of the hot material during the cooling process. Because the hot material may exhibit uneven temperature distribution within the cooling chamber due to factors such as packing density and airflow circulation, the values ​​from a single detection point are often limited and cannot accurately represent the actual overall temperature of the material. This can easily lead to misjudgments of the cooling effect, hindering the timely detection of abnormal cooling conditions and prompt maintenance. To address these issues, we propose a cooling device with multi-point temperature measurement. Utility Model Content

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Example: refer to Figure 1 and Figure 2 A cooling device with multi-point temperature measurement includes a cooler 1, which is an SKLY type cooler 1 manufactured by Honghuan Machinery Co., Ltd. A first temperature sensor 2 is installed on the surface of the cooler 1, and a second sensor is installed on the surface of the discharge hopper of the cooler 1. By adopting multi-point temperature measurement, the material temperature before, during and after cooling can be monitored in real time. The unique temperature detection abnormality alarm system can promptly report abnormal equipment conditions. The reasonable arrangement of multiple temperature measurement points at the four corners not only provides more accurate data feedback, but also avoids false alarms triggered by equipment failure, thus improving practicality.

[0017] refer to Figure 2 There are four first temperature sensors 2, which are located at the four corners of the cooler 1 housing, and one second temperature sensor 3. By setting the number of first temperature sensors 2 to four, which are located at the four corners of the cooler 1 housing, and the number of second temperature sensors 3 to one, more accurate data can be fed back, and false alarms triggered by the failure of the detection equipment can be avoided.

[0018] refer to Figure 1 The surface of the discharge hopper of cooler 1 is provided with a maintenance door 4, which facilitates maintenance.

[0019] Brief Description of Usage: The multi-point temperature detection and control system can be used in the material cooling section. The system consists of multiple temperature detectors. One detection point is placed at each of the four corners of the cooling box in cooler 1, one temperature monitoring point is placed on the material discharge hopper of cooler 1, and one monitoring point is placed indoors at a location more than 3 meters away from any heat source (e.g., ...). Figure 3 This allows us to obtain three sets of temperature data simultaneously: the temperature of the hot material, the temperature of the cooled material, and the ambient room temperature.

[0020] When hot materials are fed into the cooling chamber of cooler 1 for cooling, temperature is detected at the four corners of the cooling chamber. The temperature change of the hot materials is measured in real time and fed back to the central control system. After the set temperature is reached, the material is discharged. The temperature monitoring point in the hopper detects the material again to prevent incorrect discharge due to the failure of the temperature detector in the cooling chamber of cooler 1. The temperature difference between the temperature monitoring point in the chamber and the temperature point in the discharge hopper is compared and fed back to the central control system. The system intelligently adjusts the start, stop and speed of discharge based on the temperature difference of the finished material.

[0021] When the equipment malfunctions, fluctuations in temperature data at various points will be promptly reported to the central control system. Workers can then promptly detect the abnormality and begin inspection and repair, ensuring the high quality of finished products.

[0022] When hot materials are placed into the cooling box for cooling, temperature is detected at the four corners of the cooling box. The temperature changes of the hot materials are measured in real time and fed back to the central control system. Once the set temperature is reached, the material is discharged. The temperature monitoring point in the hopper detects the material again to prevent incorrect discharge due to the failure of the temperature detector in the cooling box. The temperature difference between the temperature monitoring point in the room and the temperature point in the discharge hopper is compared and fed back to the central control system. The system intelligently adjusts the start, stop and speed of discharge based on the temperature difference of the finished material.

[0023] When the equipment malfunctions, fluctuations in temperature data at various points will be promptly reported to the central control system. Workers can then promptly detect the abnormality and begin inspection and repair, ensuring the high quality of finished products.

[0024] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
