Description

Technical Field

[0001] This utility model relates to the field of roller conveyor technology, and in particular to an improved internal cooling device for roller conveyors. Background Technology

[0002] Currently, in metallurgical enterprises, depending on the actual working conditions, roller conveyors used in high-temperature working areas generally adopt a roller conveyor with internal cooling. This internal cooling device is widely used in industrial production. It removes the heat generated during the operation of the roller conveyor through a circulating cooling medium (such as water) to ensure the stability and service life of the roller conveyor.

[0003] Traditional roller conveyor cooling devices typically place the inlet and outlet of cold and hot water on the same side of the roller conveyor. The cooling medium must complete a round-trip path of "inflow-heat absorption-return" within the roller conveyor. This design has the following drawbacks: 1. High flow resistance: The presence of turning and recirculation areas in the round-trip path leads to increased local resistance, limiting the flow rate and velocity of the cooling medium; 2. Low heat exchange efficiency: When the hot water returns, it comes into contact with the roller conveyor again, forming "heat recirculation interference," which affects the heat absorption effect of the initial cold water. To solve the above problems, we propose this improved roller conveyor cooling device. Utility Model Content

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4As shown, an improved roller conveyor internal cooling device includes a roller conveyor body 4 and two bearing seats 1. Rotating pipes 2 are fixedly connected to both ends of the roller conveyor body 4. The rotating pipes 2 are provided with a cooling mechanism for reducing the temperature of the roller conveyor body 4. The cooling mechanism includes a transfer box 3 rotatably connected to the side wall of the rotating pipe 2. The transfer box 3 is sealed to the rotating pipe 2 by a sealing element. Multiple through holes 6 are opened on the side wall of the rotating pipe 2. The transfer box 3 is provided with a first flange pipe 5 communicating with its interior.

[0023] One of the first flange pipes 5 is equipped with a filtration mechanism for filtering water sources. The filtration mechanism includes a connecting pipe 13 set on the first flange pipe 5. A filter cylinder 11 is fixedly connected to the side wall of the connecting pipe 13. A filter screen 10 is provided inside the filter cylinder 11. A sealing cover 9 is provided on the side wall of the filter cylinder 11. A second flange pipe 8 is connected to the sealing cover 9.

[0024] In this utility model, the sealing cover 9 is threadedly connected to the filter cylinder 11, and the filter screen 10 is threadedly connected to the filter cylinder 11. The threaded connection between the sealing cover 9 and the filter cylinder 11 facilitates quick disassembly and cleaning of the filter screen, improving maintenance convenience.

[0025] In this utility model, a flow meter 12 is provided on the connecting pipe 13, and a controller 14 and an alarm 15 are provided on the transfer box 3. The flow meter 12 on the connecting pipe 13 can monitor the flow of the cooling medium in real time. The controller 14 and the alarm 15 of the transfer box 3 are linked together. When the flow is abnormal (such as below the set threshold), the alarm is automatically triggered to realize the fault warning function and avoid the roller conveyor from overheating and being damaged due to insufficient flow.

[0026] In this utility model, the roller conveyor body 4 is provided with a flow pipe 7 inside. The two sides of the roller conveyor body 4 are welded to the pipe body. The flow pipe 7 is composed of two transverse half-pipes welded together. After the partition plate 16 is welded to the inner wall of the two half-pipes, the two half-pipes are welded and polished, and then placed inside the roller conveyor body 4. Multiple partition plates 16 are fixedly connected to the inner wall of the flow pipe 7, which can prolong the water retention time in the roller conveyor body 4 and improve the cooling effect of the roller conveyor.

[0027] In this invention, multiple partitions 16 are arranged at equal intervals, and multiple through holes 6 are arranged at equal intervals to ensure that the cooling medium flows evenly into the flow pipe 7 and avoids uneven local flow.

[0028] It should be noted that this utility model is an improved internal cooling device for roller conveyors. The user connects the second flange pipe 8 to the external cold water (cooling medium) pipe, and the first flange pipe 5 on the right side to the recovery pipe. After the cold water is filtered through the first flange pipe 5, connecting pipe 13 and filter cylinder 11 of the transfer box 3 on one side, it flows evenly into the circulation pipe 7 inside the roller conveyor body 4 through the through hole 6 on the side wall of the rotating pipe 2. Under the guidance of the partition plate 16, the cold water flows unidirectionally along the "S" shaped path, fully absorbing the heat generated by the operation of the roller conveyor. After becoming hot water, it flows into the corresponding transfer box 3 from the through hole 6 of the rotating pipe 2 on the other side, and is discharged through the first flange pipe 5 on the other side.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
