Description

Technical Field

[0001] This utility model relates to the technical field of open-air water body antifreeze, specifically a winter antifreeze device for open-air tailings pond return water reservoir. Background Technology

[0002] Tailings ponds are a common tailings storage site in most mineral processing plants. Most plants use water during the mineral processing process, and to reduce water costs and environmental pollution, the water in tailings ponds is generally recycled. However, in northern open-pit tailings ponds, the water surface often freezes at the top during winter due to extremely low outside temperatures, reducing the usable return water. This increases operating costs and can even lead to production shutdowns due to untimely water replenishment. To overcome this problem, there is an urgent need to develop a method and device that can delay or even prevent the freezing of water in the pond.

[0003] To address the aforementioned issues, a winter antifreeze device for open-air tailings pond return reservoirs is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a winter antifreeze device for open-air tailings ponds and return water reservoirs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winter antifreeze device for an open-air tailings pond return water reservoir, comprising an air supply device, a heating device, and a reverse threaded bubble generator.

[0006] The air supply device is fixed on the winter water storage dam body, and the air outlet of the air supply device is connected to the air inlet of the heating device fixed on the winter water storage dam body through a primary compressed air pipe.

[0007] The reverse-threaded bubble generator includes a two-stage compressed air pipe, a suspension line, a float, and a reverse-threaded bubble generating device. The two-stage compressed air pipe includes a main pipe and a branch pipe, both of which are wrapped with insulation material. The air inlet of the main pipe is connected to the air outlet of the heating device, and the air outlet of the main pipe is connected to the air inlet of the branch pipe. The air outlet of the branch pipe is connected to the air inlet of the reverse-threaded bubble generating device. The float is connected directly above the reverse-threaded bubble generating device via the suspension line, and the float is used to ensure that the reverse-threaded bubble generating device floats in the water.

[0008] Furthermore, the air supply device is a fan, which is fixed on the winter water storage dam body, and the air outlet of the fan is connected to the primary compressed air pipe.

[0009] Furthermore, the main pipe is detachably connected to the heating device, and the branch pipes are detachably connected to both the main pipe and the reverse threaded bubble generator.

[0010] Furthermore, the reverse thread type bubble generators are evenly distributed around the circumference, and the spiral directions of the reverse thread type bubble generators are arranged in a mirror-symmetrical manner.

[0011] Furthermore, the primary compressed air duct is made of low-temperature resistant rubber.

[0012] Furthermore, the suspension line is detachably connected to the float, and the suspension line is detachably connected to the reverse threaded bubble generator.

[0013] Furthermore, the reverse-threaded bubble generator is made of rubber tubing.

[0014] Furthermore, the spiral directions of two adjacent reverse-threaded bubble generators are opposite.

[0015] Furthermore, there is a seamless connection between the main pipe and the branch pipe, and between the branch pipe and the reverse threaded bubble generator.

[0016] Analysis shows that this utility model provides a winter antifreeze device for an open-air tailings dam reservoir, including an air supply device, a heating device, and a reverse-threaded bubbler. The air supply device is fixed to the winter reservoir dam body, and the air outlet of the air supply device is connected to the air inlet of the heating device fixed to the winter reservoir dam body through a primary compressed air pipe. The air supply device provides power for gas flow, ensuring that the gas is always in a flowing state, and the primary compressed air pipe ensures that the gas can be delivered to the heating device along a predetermined trajectory, where the heating device heats the gas, allowing it to carry heat. The reverse-threaded bubbler includes a secondary compressed air pipe, a suspension line, a float, and a reverse-threaded bubble generating device. The secondary compressed air pipe includes a main pipe and branch pipes, and the main pipe and branch pipes are wrapped with insulation material. The gas temperature loss in the main pipe and branch pipe is reduced. The air inlet of the main pipe is connected to the air outlet of the heating device, the air outlet of the main pipe is connected to the air inlet of the branch pipe, and the air outlet of the branch pipe is connected to the air inlet of the reverse spiral bubble generator. The float is connected directly above the reverse spiral bubble generator by the suspension line. The float is used to ensure that the reverse spiral bubble generator floats in the water. While ensuring that the reverse spiral bubble generator can be adjusted to a designated position deep in the water, the gas's disturbance and stirring ability on the water is enhanced. The gas carrying heat is output in a spiral shape from the reverse spiral bubble generator, thereby interfering with the water crystallization around the condensation nucleus and slowing down and avoiding water freezing.

[0017] Compared with the closest existing technology, the technical solution provided by this utility model has the following advantages:

[0018] In response to the frequent occurrence of ice formation on the water surface of open-air tailings ponds in northern China during winter due to low ambient temperatures, resulting in a reduction in usable return water, this invention addresses the issue of ambient gas being introduced into a primary compressed air pipe via an air supply device. This gas is then heated by a heating device before entering a secondary compressed air pipe. A directional spiral bubble generator further enhances the agitation and stirring of the heated gas on the water. Combined with the heat carried by the gas, the water is agitated, preventing it from accumulating around ice crystal nuclei and forming large areas of ice, thus achieving winter freeze protection for open-air tailings ponds.

[0024] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0026] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a winter antifreeze device for an open-air tailings pond return water reservoir, including an air supply device 1, a heating device 2, and a reverse threaded bubbler.

[0027] The air supply device 1 is fixed on the winter water storage dam body, and the air outlet of the air supply device 1 is connected to the air inlet of the heating device 2 fixed on the winter water storage dam body through a primary compressed air pipe 3.

[0028] Gas from the external environment is introduced into the primary compressed air pipe 3 via the air supply device 1 and then sent to the heating device 2 for heating, allowing the gas to carry heat. In this embodiment, the air supply device 1 is activated when the ambient temperature is below 3°C. The heating temperature of the heating device 2 ranges from 0°C to 300°C. The air supply volume of the air supply device 1 ensures that the outlet air volume of the heating device 2 is greater than or equal to 1200 m³ / h. 3 / h, and ensure that the airflow reaching the bubble-generating end of the reverse threaded bubbler is greater than or equal to 300m³ / h. 3 / h, thereby enabling the gas to disturb and heat the water, thus slowing down and preventing the water from freezing.

[0029] The reverse-threaded bubble generator includes a secondary compressed air pipe 4, a suspension line 7, a float 8, and a reverse-threaded bubble generating device 9. The secondary compressed air pipe includes a main pipe 5 and branch pipes 6. Both the main pipe 5 and branch pipes 6 are wrapped with insulation material to keep the gas heated by the heating device 2 warm, reducing heat loss and improving energy efficiency. The air inlet of the main pipe 5 is connected to the air outlet of the heating device 2, the air outlet of the main pipe 5 is connected to the air inlet of the branch pipe 6, and the air outlet of the branch pipe 6 is connected to the air inlet of the reverse-threaded bubble generating device 9. The heated gas is delivered in equal volume to the branch pipe 6 via the main pipe 5, and then to multiple reverse-threaded bubble generators 9, which greatly improves the utilization efficiency of the gas and enhances the gas's ability to disturb and agitate the water. The float 8 is connected directly above the reverse-threaded bubble generator 9 via the suspension line 7. The float is used to ensure that the reverse-threaded bubble generator 9 floats in the water. It ensures that the reverse-threaded bubble generator 9 does not sink too deep or float too shallowly on the surface of the water, while being able to float at a specified depth in the water.

[0030] In this embodiment, to ensure a good water disturbance effect, the length of the suspension line 7 is 10cm to 20cm. That is, the water depth of the reverse thread bubble generator 9 is 10cm to 20cm below the water surface. If the water depth of the reverse thread bubble generator 9 is less than 10cm, it may reduce the amount of surface water that the reverse thread bubble generator 9 can move, thus reducing the antifreeze effect. If the water depth of the reverse thread bubble generator 9 is greater than 20cm, it may worsen the water disturbance effect near the water surface, thus reducing the antifreeze effect.

[0031] Preferably, the air supply device 1 is a fan, which is fixed on the winter water storage dam body, and the air outlet of the fan is connected to the primary compressed air pipe 3.

[0032] Because of their low energy consumption and simple maintenance, different types of fans can be selected according to different needs, and they can be installed independently. As an air supply device, the fan has significant advantages in terms of efficiency, cost and adaptability.

[0033] Preferably, the main pipe 5 is detachably connected to the heating device 2, and the branch pipe 6 is detachably connected to the main pipe 5 and the reverse threaded bubble generator 9, respectively.

[0034] When the antifreeze point changes, the main pipe 5 and branch pipe 6 can be disassembled and replaced with main pipe 5 and branch pipe 6 of different specifications to meet different needs.

[0035] Preferably, the reverse thread type bubble generator 9 is evenly distributed around the circumference, and the spiral direction of the reverse thread type bubble generator 9 is arranged in a mirror symmetrical manner.

[0036] In this embodiment, six reverse spiral bubble generators 9 are provided, three clockwise spiral and three counterclockwise spiral. This allows gas to be released into the water in a spiral shape through the reverse spiral bubble generator, improving the disturbance effect on the water body. The specific parameters of the spiral structure, such as the major diameter, minor diameter, pitch, and helix angle, can be adjusted according to the actual air volume and antifreeze effect. When the antifreeze effect is not good, the antifreeze capability can be improved by reducing the pitch, helix angle, and other parameters of the conical spiral structure and increasing the number of bubble generators.

[0037] Preferably, the primary compressed air duct 3 is made of low-temperature resistant rubber tubing.

[0038] Since the primary compressed air duct 3 transmits gas from the air supply device 1, which has not been heated and does not carry heat, the low temperature of the surrounding environment may cause damage to the primary compressed air duct 3. Therefore, the primary compressed air duct 3 is composed of a low-temperature resistant rubber tube, which improves the service life of the primary compressed air duct 3.

[0039] Preferably, the suspension line 7 is detachably connected to the float 8, and the suspension line 7 is detachably connected to the reverse threaded bubble generator 9.

[0040] The length of the suspension line 7 can be adjusted according to the on-site water surface antifreeze conditions to adjust the height of the reverse threaded bubble generator 9 above the water surface, and to select the position where the reverse threaded bubble generator 9 has the best effect on water disturbance.

[0041] Preferably, the reverse threaded bubble generator 9 is made of rubber tubing; ensuring that the reverse threaded bubble generator 9 will not sink to the bottom due to excessive weight, while being able to extend into the water at a specified depth.

[0042] More preferably, the two adjacent reverse spiral bubble generators 9 have opposite spiral directions, in order to improve the disturbance effect on the water body, which is more conducive to the water body's antifreeze and to slow down and avoid the water body from freezing.

[0043] Preferably, the main pipe 5 and the branch pipe 6 are seamlessly connected, and the branch pipe 6 and the reverse threaded bubble generator 9 are seamlessly connected, to ensure that the gas provided by the air supply device 1 will not leak during the transportation process, thereby improving the sealing performance of the device, reducing energy consumption, and lowering costs.

[0044] The process of using this device to prevent the water in the open-air tailings dam from freezing in winter is as follows:

[0045] During the preparation phase, the length of the suspension line 7, as well as the lengths of the primary compressed air pipe 3 and the secondary compressed air pipe 4, are adjusted according to the on-site water surface antifreeze conditions. The reverse threaded bubble generator 9 is then inserted into the water to a specified depth. During the operation phase, the air supply device 1 and the heating device 2 are activated. Gas from the external environment is transported to the heating device 2 through the primary compressed air pipe 3, heating the gas to a specified temperature. The gas is then transported to the reverse threaded bubble generator 9 through the secondary compressed air pipe 4 and discharged through the outlet of the reverse threaded bubble generator 9. This disturbs the water, keeping it in a flowing state. The disturbance disrupts and disturbs the condensation nuclei that have already formed, and interferes with the crystallization of water around the condensation nuclei into ice, thereby slowing down and preventing water from freezing.

[0046] In summary, this utility model achieves the following technical effects:

[0047] 1) Low-temperature resistant rubber tubing is used as the primary compressed air pipe 3 to ensure that the primary compressed air pipe 3 will not break due to low temperature in low-temperature environments, thereby affecting the sealing performance of the device and reducing the disturbance efficiency to the water body.

[0048] 2) The secondary compressed air pipe 4 is wrapped with heat insulation material to reduce the heat loss of the heated gas after passing through the heating device 2, and to ensure that the heat carried by the heated gas can be transferred to the water body to the maximum extent, thereby interfering with the water body condensing into ice.

[0049] 3) Using a fan as the air supply device 1 allows for the selection of different types of fans according to the needs of different environments, improving the adaptability of the device to different environments and increasing the energy utilization efficiency of the fan.

[0050] 4) The gas output from the air supply device 1 is heated by the heating device 2, so that the gas can carry heat and further slow down the freezing of the water.

[0051] 5) The reverse spiral bubble generator 9 is evenly distributed around the circumference, and the spiral direction is arranged in a mirror symmetrical manner, and the spiral directions of two adjacent reverse spiral bubble generators 9 are opposite; so that the gas is output along the outlet of the reverse spiral bubble generator 9, and the gas is released into the water in a spiral shape through the reverse spiral bubble generator, so as to improve the disturbance ability of the water body.

[0052] 6) The main pipe 5 and the branch pipe 6 are seamlessly connected, and the branch pipe 6 and the reverse threaded bubble generator 9 are seamlessly connected, which further improves the sealing of the gas during the transportation process and avoids weakening the disturbance effect of the gas on the water.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
