Description

Technical Field

[0001] This utility model relates to the field of coal gangue storage, specifically a coal gangue heat dissipation device. Background Technology

[0002] Coal gangue is a solid waste discharged during coal mining and washing. It is a dark gray rock with a low carbon content and harder than coal, which is associated with coal seams during coal formation. It includes gangue from tunnel excavation, gangue extracted from the roof, floor, and interlayers during mining, and gangue from coal washing. Coal gangue is a mixture of carbonaceous, argillaceous, and sandy shale, with a low calorific value. It contains 20%–30% carbon and some contains humic acid. China has accumulated approximately 1000 Mt of coal gangue over the years, and continues to discharge about 100 Mt annually. This not only occupies land but also poses a risk of spontaneous combustion, polluting the air or causing fires.

[0003] Current coal gangue heat dissipation devices, as described in patent announcement number CN212362928U, include a hollow steel pipe with a vacuum inside containing an inorganic heat transfer medium. A heat dissipation medium pipe is installed on the outside of the steel pipe, and the heat dissipation medium pipe has an inlet and an outlet.

[0004] Regarding the aforementioned technologies, the inventors believe that the steel pipes need to be inserted into the coal gangue piles during use. However, since coal gangue piles are composed of a large amount of coal gangue, most machinery cannot be moved onto them. As a result, when inserting the steel pipes into the coal gangue piles, workers often need to manually press the steel pipes down to insert them into the piles. This method is not only time-consuming and labor-intensive, but also has low installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a coal gangue heat dissipation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coal gangue heat dissipation device, comprising

[0008] A heat dissipation mechanism includes a hollow column, the top of which is detachably connected to a plug. An inlet pipe and a drain pipe are respectively fixed through the two sides of the inside of the plug. A heat exchange pipe is fixedly connected between the bottom of the inlet pipe and the drain pipe.

[0009] The installation mechanism includes a spiral blade plate fixedly connected to the outside of the hollow column, the spiral blade plate being arranged in a spiral shape.

[0010] As a further embodiment of this utility model: the plug is threadedly connected to the hollow column, and multiple protruding strips are fixedly connected to the outer side of the plug in a ring array.

[0011] As a further embodiment of this utility model: a sealing ring is fixedly connected to the bottom of the plug, and the sealing ring abuts against the hollow column.

[0012] As a further embodiment of this utility model: multiple rotating rods are fixedly connected in a ring array on the outer side of the hollow column, and a rotating ring is fixedly connected to the end of each group of rotating rods away from the hollow column.

[0013] As a further embodiment of this utility model: the heat exchange tube is arranged in a spiral shape, and the bottom of the plug is fixedly connected with multiple first fin plates in a ring array. Each group of first fin plates is disposed inside the hollow column, and the heat exchange tube passes through each group of first fin plates and is fixedly connected to each group of first fin plates.

[0014] As a further embodiment of this utility model: the inner wall of the hollow column is fixedly connected in a ring array with a plurality of second fin plates, the second fin plates corresponding to the rotor plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With the above-described structure, this invention, through the cooperation of the hollow column and the swivel plate, allows the hollow column to be placed vertically on the coal gangue pile for heat exchange and cooling when it is necessary to insert it into the coal gangue pile. The hollow column is then rotated, causing the swivel plate to rotate. As the swivel plate rotates, it gradually spirals into the coal gangue, thus inserting the hollow column into the coal gangue pile. This makes inserting the hollow column into the coal gangue pile easier and improves the installation efficiency of the entire heat dissipation device. Simultaneously, the swivel plate increases the surface area of ​​the outer side of the hollow column, thereby improving heat conduction efficiency and ultimately enhancing the heat dissipation effect on the coal gangue.

[0017] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings, but this does not constitute any limitation on the present invention.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4 A coal gangue heat dissipation device includes a heat dissipation mechanism 1, which includes a hollow column 101. The interior of the hollow column 101 is used to hold water, so that after the hollow column 101 is inserted into the coal gangue pile, heat can be conducted through the hollow column 101 to the water inside the hollow column 101. Multiple second finned plates 109 are fixedly connected in a ring array on the inner wall of the hollow column 101. The second finned plates 109 correspond to a swivel plate 201. The arrangement of the second finned plates 109 increases the surface area of ​​the inner wall of the hollow column 101, thereby improving the heat exchange effect between the hollow column 101 and the water inside the hollow column 101. An installation mechanism 2 includes a swivel plate 201 fixedly connected to the outside of the hollow column 101. The swivel plate 201 is spirally arranged, which facilitates its insertion into the coal gangue during rotation, making it easier to insert the hollow column 101 into the coal gangue.

[0025] Multiple rotating rods 202 are fixedly connected in a ring array on the outer side of the hollow column 101. A rotating ring 203 is fixedly connected to the end of each rotating rod 202 away from the hollow column 101. The arrangement of the rotating rods 202 and rotating rings 203 facilitates the rotation and adjustment of the hollow column 101. A plug 102 is detachably connected to the top of the hollow column 101, used to cover the top of the hollow column 101. The plug 102 is threaded to the hollow column 101 for easy disassembly. Multiple protruding strips 103 are fixedly connected in a ring array on the outer side of the plug 102. The protruding strips 103 facilitate the rotation of the plug 102, thus facilitating its installation and removal. This allows the plug 102 to be unscrewed and reused when the hollow column 101 is severely worn due to repeated insertion and removal from the coal gangue pile, requiring replacement. Only the hollow column 101 needs to be replaced, thereby reducing the maintenance cost of the entire heat dissipation device.

[0026] A sealing ring 106 is fixedly connected to the bottom of the plug 102. The sealing ring 106 abuts against the hollow column 101, and the sealing ring 106 is used to seal the gap between the plug 102 and the hollow column 101. A water inlet pipe 104 and a drain pipe 105 are fixedly connected through the two sides of the inside of the plug 102, respectively. A heat exchange pipe 107 is fixedly connected between the bottom of the water inlet pipe 104 and the drain pipe 105. The water inlet pipe 104 is used to connect to the input end of the water pump, so that when the water pump starts working, it can draw water into the interior of the heat exchange pipe 107 and then discharge it from the drain pipe 105. This allows the water inside the hollow column 101 to exchange heat with the water flowing inside the heat exchange pipe 107, thereby removing the heat from the water inside the hollow column 101.

[0027] The heat exchange tube 107 is arranged in a spiral shape, which increases the flow of water inside the heat exchange tube 107, thereby improving the heat exchange effect with the water inside the hollow column 101. Multiple first finned plates 108 are fixedly connected in a ring array at the bottom of the plug 102. Each set of first finned plates 108 is disposed inside the hollow column 101. The heat exchange tube 107 passes through each set of first finned plates 108 and is fixedly connected to each set of first finned plates 108. The arrangement of the first finned plates 108 further fixes the heat exchange tube 107, thereby improving its stability and increasing its surface area, thus improving the heat exchange effect with the water inside the hollow column 101.

[0028] In use, pour water into the hollow column 101, then tighten the plug 102 until the sealing ring 106 moves downwards and abuts against the hollow column 101. Then, place the hollow column 101 vertically on top of the coal gangue pile. Next, rotate the rotating ring 203, which, through the rotating rods 202, drives the hollow column 101 and the swivel plate 201 to rotate. As the swivel plate 201 rotates, it gradually screws into the coal gangue pile, thereby inserting the hollow column 101 into the pile. Finally, connect the water inlet pipe 104 to the water pump. The water pump is then started, and the drain pipe 105 is connected to the water pipe. The water is then drawn into the inlet pipe 104 and flows through the heat exchange tube 107 before being discharged into the water pipe through the drain pipe 105. The heat inside the coal gangue pile is conducted to the water inside the hollow column 101 through the swivel plate 201, the hollow column 101, and the second finned plate 109. The heat is then exchanged with the water flowing inside the heat exchange tube 107 through the first finned plate 108 and the heat exchange tube 107, thereby removing the heat and achieving internal cooling of the coal gangue.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
