Description

Technical Field

[0001] The utility model relates to a facility for preventing freezing of water areas around a drainage well of a tailings pond in winter, belonging to the technical field of anti-freezing facilities for water areas around a drainage well of a tailings pond. Background Art

[0002] In cold areas, ice will freeze and form thick ice layers in the tailings pond in winter and early spring. Since the drainage well is located in the tailings pond, the ice layer will collide and squeeze the drainage well due to its volume expansion when it freezes. At the same time, when the ice layer melts, the larger ice blocks will also continue to collide with the drainage well with the flow of water, which seriously reduces the stability of the drainage well frame. At the same time, the collision will also damage the surface of the drainage well, causing cracks, breakage, and falling off of the concrete and mortar layers, posing a great safety hazard to the structural stability of the drainage well. Summary of the invention

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and provide a facility to prevent freezing of the surrounding waters of the tailings pond drainage well in winter.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A facility for preventing freezing of waters around a tailings pond drainage well in winter, comprising: a floating bridge platform, a first vertical silt removal pump, a second vertical silt removal pump, an outlet butterfly valve of the first vertical silt removal pump, an outlet butterfly valve of the second vertical silt removal pump, a first connecting elbow, a second connecting elbow, an annular pipeline and an annular pipeline branch pipe;

[0006] Among them, the drainage well is located in the center of the floating bridge platform, the ring pipeline is laid on the edge of the floating bridge platform, the outlet of the first vertical dredging pump is equipped with a first vertical dredging pump outlet butterfly valve, the first vertical dredging pump is connected to the ring pipeline through a first connecting elbow, the outlet of the second vertical dredging pump is equipped with a second vertical dredging pump outlet butterfly valve, the second vertical dredging pump is connected to the ring pipeline through a second connecting elbow, and multiple ring pipeline branches are evenly distributed on the ring pipeline.

[0007] Furthermore, the first vertical silt removal pump and the second vertical silt removal pump are suspended on the outer side of the floating bridge platform, symmetrically arranged and kept in one running and one standby state.

[0008] Furthermore, each annular pipeline branch pipe inlet is equipped with an annular pipeline branch pipe inlet ball valve.

[0009] Furthermore, the ball valve at the inlet of the annular pipeline branch can adjust the outlet pressure and water output of the annular pipeline branch according to the outdoor temperature and the freezing and thawing conditions of the drainage well and the water area around the floating bridge.

[0010] The beneficial effects of the utility model are:

[0011] The utility model can make a certain area around the drainage well in an unfrozen state all year round, eliminating the hidden danger of the frozen layer on the stability of the drainage well structure.

[0012] The drainage well of the utility model is located in the center of the floating bridge platform. Two vertical silt removal pumps are suspended on the outside of the floating bridge platform and arranged symmetrically and kept in a state of one open and one standby. The outlet of the vertical silt removal pump is equipped with a butterfly valve and connected to the annular pipeline through a connecting elbow; the annular pipeline is laid on the edge of the floating bridge platform, and multiple branch pipes are evenly distributed on the annular pipeline. The inlet of the branch pipe is equipped with a ball valve. The vertical silt removal pump sucks water into the annular pipeline, and then the water flows out through the annular pipeline branch controlled by the ball valve to shoot the water surface. This method is called "pressure water injection method". Through this method, a water flow flowing around the floating bridge platform can be formed around the drainage well. The utility model can make the surrounding area of ​​the drainage well and a certain area around the floating bridge platform in an unfrozen state all year round, avoiding the safety hazard caused by the direct or indirect squeezing and impact of the frozen layer on the drainage well frame, so as to ensure the safety and stability of the drainage well structure.

[0013] The utility model can make a certain area around the drainage well of the tailings pond in the cold northern region in an unfrozen state all year round, eliminating the hidden dangers caused by the frozen layer to the stability of the drainage well structure. In the winter and early spring seasons in the cold northern region, the outdoor temperature is usually below 0°C, and the extremely cold weather can reach minus 40°C. A thicker ice layer will freeze in the water area of ​​the tailings pond. Since the drainage well is located in the tailings pond, the ice layer will collide and squeeze the drainage well frame due to the expansion of volume when freezing. At the same time, when the ice layer melts, the larger ice blocks that split will also continuously collide with the drainage well with the flow of water. Once a collision occurs, it will have a great impact on the stability of the drainage well frame. At the same time, the collision will also damage the surface of the drainage well, causing cracks, damage, and falling off of the concrete and mortar layers, causing great safety hazards to the structural stability of the drainage well. The utility model can make a certain area around the drainage well in an unfrozen state all year round, avoiding the frozen layer from directly or indirectly squeezing and colliding with the drainage well frame, so as to ensure the safety and stability of the drainage well structure.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method is given, but the protection scope of the present invention is not limited to the following embodiments.

[0020] like Figures 1 to 4 As shown, a facility for preventing freezing of waters around a tailings pond drainage well in winter according to this embodiment includes: a floating bridge platform 2, a first vertical silt removal pump 3, a second vertical silt removal pump 4, a first vertical silt removal pump outlet butterfly valve 5, a second vertical silt removal pump outlet butterfly valve 6, a first connecting elbow 7, a second connecting elbow 8, an annular pipeline 9 and an annular pipeline branch pipe 10;

[0021] Among them, the drainage well 1 is located in the center of the floating bridge platform 2, the annular pipeline 9 is laid on the edge of the floating bridge platform 2, the outlet of the first vertical dredging pump 3 is equipped with a first vertical dredging pump outlet butterfly valve 5, the first vertical dredging pump 3 is connected to the annular pipeline 9 through a first connecting elbow 7, the outlet of the second vertical dredging pump 4 is equipped with a second vertical dredging pump outlet butterfly valve 6, the second vertical dredging pump 4 is connected to the annular pipeline 9 through a second connecting elbow 8, and a plurality of annular pipeline branches 10 are evenly distributed on the annular pipeline 9.

[0022] The first vertical desilting pump 3 and the second vertical desilting pump 4 are suspended on the outer side of the floating bridge platform 2 and are symmetrically arranged and maintained in a state of one being in operation and the other being in standby.

[0023] The inlet of each annular pipeline branch pipe 10 is equipped with an annular pipeline branch pipe inlet ball valve 11.

[0024] The annular pipeline branch pipe inlet ball valve 11 can adjust the outlet pressure and water output of the annular pipeline branch pipe 10 according to the outdoor temperature and the freezing and thawing conditions of the drainage well and the water area around the floating bridge.

[0025] Example 1

[0026] like Figure 2 and Figure 3As shown, the drainage well 1 is located in the center of the floating bridge platform 2, the annular pipeline 9 is laid on the edge of the floating bridge platform 2, the outlet of the first vertical silt removal pump 3 is equipped with a first vertical silt removal pump outlet butterfly valve 5, the first vertical silt removal pump 3 is connected to the annular pipeline 9 through a first connecting elbow 7, the outlet of the second vertical silt removal pump 4 is equipped with a second vertical silt removal pump outlet butterfly valve 6, the second vertical silt removal pump 4 is connected to the annular pipeline 9 through a second connecting elbow 8, and a plurality of annular pipeline branches 10 are evenly distributed on the annular pipeline 9, and an annular pipeline branch inlet ball valve 11 is installed at the inlet of each annular pipeline branch 10.

[0027] The drainage well 1 is located in the center of the floating bridge platform 2, which prevents the ice layer in the tailings pond from directly squeezing and impacting the drainage well 1, thereby improving the stability of the drainage well frame.

[0028] The first vertical silt removal pump 3 and the second vertical silt removal pump 4 are suspended and arranged symmetrically on the outside of the floating bridge platform 2 and maintained in an open and a standby state, so that when one pump fails, the other pump can be turned on to continue working, avoiding the facility from being unable to operate normally when one pump fails; at the same time, the use of vertical silt removal pumps with simple maintenance and low failure rate can also avoid overload operation of the motor when the clear liquid layer around the drainage well is shallow and the water concentration is high, causing damage to the motor.

[0029] The outlets of the first vertical silt removal pump 3 and the second vertical silt removal pump 4 are both equipped with the first vertical silt removal pump outlet butterfly valve 5 and the second vertical silt removal pump outlet butterfly valve 6, which are connected to the annular pipeline 9 through the first connecting elbow 7 and the second connecting elbow 8. When one of the vertical silt removal pumps is turned on, its outlet butterfly valve is also opened, so that the water sucked by the pump can enter the annular pipeline 9. The other vertical silt removal pump is used as a standby pump. When it is not turned on, the butterfly valve is closed to prevent the water flow in the annular pipeline from flowing back into the standby pump body and causing the impeller to reverse and burn the motor.

[0030] like Figure 1 As shown, the annular pipeline 9 is laid on the edge of the floating bridge platform 2 to avoid occupying a larger floating platform space and affecting the workers' inspection and operation. At the same time, as the water level rises, the floating bridge platform 2 will also rise accordingly, and the aisle of the floating bridge platform 2 will also be artificially extended to the shore. The annular pipeline 9 is extended to the end of the aisle to continue to realize the original intention of the design.

[0031] A plurality of annular pipeline branches 10 are evenly distributed on the annular pipeline 9, so that water flows from the annular pipeline 9 into the annular pipeline branch 10 through the annular pipeline branch inlet ball valve 11 and flows out, thereby forming a circulating water flow flowing around the floating bridge platform 2, preventing water from freezing around the drainage well 1 and in a certain area around the floating bridge platform 2, and also preventing the floating bridge platform 2 from being hit by the ice layer and colliding with the drainage well 1.

[0032] like Figure 4As shown, each annular pipeline branch pipe 10 inlet is equipped with an annular pipeline branch pipe inlet ball valve 11, which is convenient for workers to operate. Workers can adjust the outlet pressure and water output of the annular pipeline branch pipe 10 according to the outdoor temperature and the freezing and thawing conditions of the drainage well and the water area around the floating bridge.

[0033] The above are only preferred specific embodiments of the present invention, which are all different implementations based on the overall concept of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
