Description

Technical Field

[0001] This utility model relates to the field of steam boiler technology, and in particular to vertical finned tube oil / gas steam boilers. Background Technology

[0002] A finned tube steam boiler is a type of boiler equipment that uses finned tubes as heat transfer elements. Finned tubes are highly efficient heat transfer elements; by adding fins to the surface of the heat exchange tube, the heat exchange area is increased, thereby improving heat transfer efficiency.

[0003] A search revealed an application with application number CN202420125932.8: an angle-adjustable finned tube heat dissipation structure. This utility model involves moving a pull frame to the right, causing the connecting frame to move and rotate to the right, which in turn causes the support rod to rotate on the support block, thereby rotating the fins. This allows for adjustment of the fin angle, optimizing the flow path of airflow or liquid between the fins, and achieving a more efficient heat exchange effect.

[0004] In the above-mentioned utility model, the fin structure is relatively complex. Although the fin angle can be adjusted, the adjustment of the fin angle will also affect the contact area between the fin and the heat exchange tube, which will reduce the heat exchange effect of the fin to a certain extent.

[0005] To address these shortcomings, we proposed a vertical finned tube oil / gas steam boiler. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vertical finned tube oil / gas / steam boiler.

[0007] The objective of this utility model is achieved through the following technical solution: a vertical finned tube oil / gas / steam boiler, comprising a boiler body, an inlet pipe and an outlet pipe respectively installed on one side of the boiler body, and a diversion pipe installed at the end of both the inlet pipe and the outlet pipe, and a booster pump installed on the surface of the inlet pipe, a heat exchange tube installed on the side surface of the diversion pipe, the heat exchange tube being installed between two sets of horizontal plates, and a guide pipe being provided between adjacent heat exchange tubes, a heat-conducting ball being provided on the surface of the heat exchange tube, and a heat-conducting silicone pad being provided on the surface of the heat-conducting ball, fins being connected to the side surface of the heat-conducting ball via a rotating shaft, a connecting frame being installed on the side surface of the fins, a transmission rod being provided on one side of the connecting frame, the transmission rod being connected to a lead screw, and the lead screw being installed at the output end of a servo motor, the servo motor being installed on the side surface of the side plate, the side plate being fixedly connected to the horizontal plate, and a fan being installed on the back of the horizontal plate via a mounting bracket.

[0008] Preferably, a cleaning roller is provided inside the heat exchange tube, and a collection box is connected to the lower surface of the heat exchange tube. A first drive wheel is provided on the surface of the cleaning roller, and adjacent first drive wheels are connected by a first drive belt. The first drive wheel is connected to a second drive wheel by a second drive belt, and the second drive wheel is installed at the output end of the drive motor.

[0009] Preferably, a valve is provided on the surface of the diversion pipe.

[0010] Preferably, the collection box and heat exchange tube adopt a threaded detachable structure.

[0011] Preferably, the lower surface of the side plate is provided with casters.

[0012] Preferably, the side surface of the side panel is provided with a control panel.

[0013] This utility model has the following advantages:

[0014] (1) When using this utility model, start the booster pump to pump the hot water produced by the boiler body into the heat exchange tube. Then start the servo motor. The servo motor drives the lead screw and drives the transmission rod. Under the action of the transmission rod and the connecting frame, the fins are driven, so that the fins rotate around the rotating shaft. During the rotation of the fins, the thermally conductive silicone pad will always be in contact with the fins. The heat of the hot water passes through the heat exchange tube, the thermally conductive ball and the thermally conductive silicone pad in sequence, and then is conducted out through the fins. Under the action of the fan, the hot air is transferred along the direction of the fins to achieve a more efficient heat exchange effect.

[0015] (2) After long-term use, the present invention starts the transmission motor, drives the second transmission wheel, and drives one of the cleaning rollers under the action of the second transmission wheel, the first transmission wheel and the second transmission belt. At the same time, under the action of the first transmission wheel and the first transmission belt, all the cleaning rollers rotate synchronously to clean the inner wall of the heat exchange tube, so as to avoid dirt adhering to the inner wall of the heat exchange tube and affecting the heat exchange effect.

[0029] In one embodiment, during use, the booster pump is started to pump the hot water produced by the boiler body 1 into the heat exchange tube 7. Then, the servo motor 15 is started, which drives the lead screw 14 and the transmission rod 13. Under the action of the transmission rod 13 and the connecting frame 12, the fins 11 are driven to rotate around the rotating shaft. During the rotation of the fins 11, the thermally conductive silicone pad 10 will always be in contact with the fins 11.

Under the action of the fan 24, hot air is transported along the direction of the fins 11 to achieve a more efficient heat exchange effect. After a long period of use, the drive motor 26 is started to drive the second drive wheel 18. Under the action of the second drive wheel 18, the first drive wheel 17 and the second drive belt 25, one of the cleaning rollers 16 is driven. At the same time, under the action of the first drive wheel 17 and the first drive belt 19, all the cleaning rollers 16 rotate synchronously to clean the inner wall of the heat exchange tube 7 and prevent dirt from adhering to the inner wall of the heat exchange tube 7, which would affect the heat exchange effect.
