Abstract
Description
Technical Field
[0001] This invention relates to the field of salt mining equipment technology, and in particular to a horizontal mixed-flow pump for brine extraction and transportation in salt lakes. Background Technology
[0002] Salt lakes are a type of saline lake, a type of lake with high salinity in arid regions. Freshwater lakes have a mineralization of less than 1 gram per liter, while saline lakes have a mineralization of more than 1 gram per liter. Salt lakes have a mineralization of more than 35 grams per liter. Salt lakes are a product of the late stage of lake development. They are rich in various salts and are important mineral resources.
[0003] Existing horizontal mixed-flow pumps used for brine extraction and transportation in salt lakes suffer from high salt concentrations. During long-term brine transportation, salt precipitates out and adheres to the inside of the pump, causing blockages in the transmission structure. This also increases the weight of the impeller and unnecessary power consumption. Cleaning the salt particles inside the pump is also very troublesome. Summary of the Invention
[0004] This invention provides a horizontal mixed-flow pump for brine extraction and transportation in salt lakes, which solves the technical problem of the difficulty in cleaning salt particles adhering to the inside of the mixed-flow pump.
[0005] To solve the above-mentioned technical problems, the present invention provides a horizontal mixed-flow pump for brine extraction and transportation in salt lakes, including a base frame. A power motor is fixed to the upper end of the base frame by bolts. One end of the power motor is driven by a power shaft. A transmission shaft is fixedly connected to the other end of the power shaft relative to the power motor. A fixing pipe is fixed to the other end of the transmission shaft relative to the power shaft. A fixing flange is fixed to the upper end of the fixing pipe. A disassembly pipe is detachably connected to the surface of the fixing flange and the fixing pipe.
[0006] Preferably, the fixed pipe includes a pipe body, a fixed block is fixed on the surface of the pipe body, an impeller is rotatably connected inside the pipe body, the impeller is connected to a transmission rod inside the transmission shaft, a connecting block is fixedly connected to the fixed block by bolts, a pipe wall is fixed in the middle of the connecting block, a positioning seat is fixed at the lower end of the pipe wall, and a water inlet pipe is fixed at the other end of the pipe wall opposite to the pipe body.
[0007] Preferably, a sealing gasket is fixed to the surface of the pipe wall, and the sealing gasket is inserted into the fixing groove.
[0008] Preferably, the fixed flange includes a disc body, and an outer fixing ring and an inner fixing ring are fixed at the lower end of the disc body.
[0009] Preferably, the outer diameter of the inner fixing ring is equal to the inner diameter of the connection between the fixing tube and the disassembly tube, and the inner diameter of the outer fixing ring is equal to the outer diameter of the connection between the fixing tube and the disassembly tube.
[0010] Preferably, the lower ends of the inner surface of the outer fixing ring and the outer surface of the inner fixing ring are respectively provided with outwardly inclined and inwardly inclined guide slopes.
[0011] Preferably, the surfaces of the fixing tube and the disassembly tube are provided with a fixing frame, and an extrusion plate is slidably connected inside the fixing frame. One end of the extrusion plate is rotatably connected to a screw, and a rotating disk is fixed to the other end of the screw relative to the extrusion plate.
[0012] Preferably, the surface of the extrusion plate is provided with a rotating cavity, and the surface of the screw is provided with a protrusion that is rotatably connected to the rotating cavity.
[0013] Compared with related technologies, the horizontal mixed-flow pump for brine extraction and transportation in salt lakes provided by this invention has the following beneficial effects:
[0014] 1. This invention achieves the removal of the disassembly pipe through bolt connection. When there is too much deposit inside the mixed flow pump, the disassembly pipe can be removed to clean the deposits on the surface of the fixed pipe, the disassembly pipe and the impeller, restore the internal capacity of the fixed pipe and the disassembly pipe, increase the water delivery volume, and at the same time reduce the weight of the impeller and reduce energy waste.
[0015] 2. This invention connects the fixed pipe and the disassembly pipe through a fixed flange, which can specify the distance between the disassembly pipe and the fixed pipe, thereby preventing water overflow from the flange connection after installation. At the same time, the guide slope and elastic ring at the bottom of the outer and inner fixed rings can ensure the convenience of disassembly pipe removal and installation.
[0016] 3. This invention uses a positioning device to determine the relative positions of the disassembly tube and the fixing tube before bolt fixing, and ensures that the upper and lower connections of the disassembly tube and the fixing tube are equally tight by intermittently rotating the rotating discs on the surface of the upper and lower positioning devices, ensuring that the sealing gasket is squeezed to the right degree, and ensuring the sealing effect after fixing.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0026] Example 1, by Figure 1-4 A horizontal mixed-flow pump for brine extraction and transportation in salt lakes is provided, comprising a base frame 5. A power motor 4 is bolted to the upper end of the base frame 5. A power shaft 3 is driven to one end of the power motor 4. A transmission shaft 2 is fixedly connected to the other end of the power shaft 3 relative to the power motor 4. A fixing pipe 6 is fixed to the other end of the transmission shaft 2 relative to the power shaft 3. A fixing flange 1 is fixed to the upper end of the fixing pipe 6. A disassembly pipe 7 is detachably connected to the surface of the fixing flange 1 and the fixing pipe 6. The fixing pipe 6 includes a pipe body 61. A fixing block 62 is fixed to the surface of the pipe body 61. An impeller 63 is rotatably connected inside the pipe body 61. The impeller 63 is driven to a transmission rod inside the transmission shaft 2. A connecting block 72 is bolted to the fixing block 62. A pipe wall 71 is fixed to the middle of the connecting block 72. A positioning seat 73 is fixed to the lower end of the pipe wall 71. A water inlet pipe 74 is fixed to the other end of the pipe wall 71 relative to the pipe body 61. A sealing gasket 75 is fixed to the surface of the pipe wall 71 and is inserted into the fixing groove 64.
[0027] Pipes are connected to the surfaces of the fixed flange 1 and the inlet pipe 74, and the power supply of the motor 4 is connected. The motor 4 drives the power shaft 3 to rotate, which in turn drives the transmission rod inside the transmission shaft 2 to rotate. The transmission rod then drives the impeller 63 to rotate. The rotation of the impeller 63 draws the brine inside the pipe connected to the inlet pipe 74 into the fixed pipe 6 and the disassembly pipe 7. The rotating impeller 63 guides the brine into the pipe on the surface of the fixed flange 1, completing the brine transportation. When the mixed flow pump has been used for a long time and there is too much deposit inside the fixed pipe 6 and the disassembly pipe 7, the bolts on the surfaces of the fixed block 62 and the connecting block 72 are removed, and then the bolts on the surface of the positioning seat 73 are removed. The disassembly pipe 7 is then tilted downwards and removed from the surface of the fixed flange 1. The disassembly pipe 7 and the fixed pipe 6 are then separated, thereby cleaning the deposits on the surfaces of the fixed pipe 6, the disassembly pipe 7, and the impeller 63.
[0028] Example 2, by Figure 1-5 A horizontal mixed-flow pump for brine extraction and transportation in salt lakes is provided, comprising a base frame 5, a power motor 4 fixed to the upper end of the base frame 5 by bolts, a power shaft 3 connected to one end of the power motor 4, a drive shaft 2 fixedly connected to the other end of the power shaft 3 relative to the power motor 4, a fixed pipe 6 fixed to the other end of the drive shaft 2 relative to the power shaft 3, a fixed flange 1 fixed to the upper end of the fixed pipe 6, and a disassembly pipe 7 detachably connected to the surface of the fixed flange 1 and the fixed pipe 6. The fixed flange 1 includes a disc body 11, and an outer fixed ring 12 and an inner fixed ring 13 fixed to the lower end of the disc body 11.
[0029] The outer fixing ring 12 and the inner fixing ring 13 are fixed to the surface of the fixing tube 6. The bottom of the outer fixing ring 12 and the inner fixing ring 13 is provided with an elastic ring. When the disassembly tube 7 needs to be removed, the lower end of the disassembly tube 7 is slightly tilted, so the disassembly tube 7 is separated from the rigid part of the outer fixing ring 12 and the inner fixing ring 13. When the disassembly tube 7 is pulled, the disassembly tube 7 squeezes the elastic ring and is separated from the fixing flange 1. When the disassembly tube 7 is installed, the outer fixing ring 12 and the inner fixing ring 13 are sleeved on the top of the disassembly tube 7 to restrict the position of the disassembly tube 7.
[0030] Example 3, by Figure 1-7 A horizontal mixed-flow pump for brine extraction and transportation in salt lakes is provided, comprising a base frame 5, a power motor 4 fixed to the upper end of the base frame 5 by bolts, a power shaft 3 connected to one end of the power motor 4, a transmission shaft 2 fixedly connected to the other end of the power shaft 3 relative to the power motor 4, a fixed pipe 6 fixed to the other end of the transmission shaft 2 relative to the power shaft 3, a fixed flange 1 fixed to the upper end of the fixed pipe 6, a disassembly pipe 7 detachably connected to the surface of the fixed flange 1 and the fixed pipe 6, a fixed frame 81 provided on the surface of the fixed pipe 6 and the disassembly pipe 7, a pressing plate 82 slidably connected inside the fixed frame 81, a screw 83 rotatably connected to one end of the pressing plate 82, and a rotating disk 84 fixed to the other end of the screw 83 relative to the pressing plate 82.
[0031] When the mixed-flow pump cleaning is complete and the disassembly pipe 7 needs to be installed, align the disassembly pipe 7 with the outer fixing ring 12 and inner fixing ring 13 on the surface of the fixed flange 1. Push the bottom of the tilted disassembly pipe 7 to move it, so that the top of the disassembly pipe 7 is stuck in the middle of the outer fixing ring 12 and inner fixing ring 13. At this time, pry the disassembly pipe 7 to make the sealing gasket 75 stably inserted into the fixing groove 64. Move the positioning device 8 so that the fixing frame 81 is placed on the surface of the fixed pipe 6 and the disassembly pipe 7. Place one on the top and one on the bottom of the surface of the fixed pipe 6 and the disassembly pipe 7, and rotate the upper and lower parts intermittently. The rotating disk 84 on the surface of the positioning device 88 drives the screw 83 to rotate. The screw 83 drives the extrusion plate 82 to move through the thread on its surface. The extrusion plate 82 moves along the sliding groove inside the fixed frame 81 and presses against the surface of the disassembly tube 7, causing the sealing gasket 75 to be deformed. Bolts are connected to the surfaces of the fixing block 62 and the connecting block 72 to fix the positioning seat 73 to the surface of the base frame 5. After fixing, the rotating disk 84 is rotated in the opposite direction to remove the positioning device 8 and complete the installation of the disassembly tube 7.
