Description

Technical Field

[0001] The invention relates to the technical field of hydraulic turbine equipment, in particular to a coaxial hydraulic turbine equipment with an energy recovery mechanism. Background Art

[0002] In modern industrial production, many process flows involve the handling and transportation of high-pressure fluids. For example, in the petrochemical, electric power, metallurgical and other industries, a large amount of high-pressure liquids are usually discharged in a low-pressure state after completing the process tasks. These high-pressure liquids contain huge amounts of energy. According to statistics, in the petrochemical industry alone, the energy waste caused by the failure to recover the energy of high-pressure liquids is considerable each year. With the global emphasis on energy conservation and sustainable development, how to effectively recover the energy that was originally wasted has become the focus of attention in the industrial and scientific research fields. Hydraulic turbines, as a device that can convert the pressure energy of liquids into mechanical energy, came into being.

[0003] The structure of early hydraulic turbine equipment was relatively simple and was mainly designed based on the single-stage turbine principle. This type of equipment can achieve a certain degree of energy recovery under some low-pressure and small-flow conditions. However, with the continuous expansion of industrial production scale and the improvement of energy recovery efficiency requirements, the limitations of traditional single-stage hydraulic turbines have gradually become apparent. However, multi-stage hydraulic turbines are more complex in structure, bulky in size, and have higher installation and maintenance costs.

[0004] The coaxial structure is beneficial to improving the operating stability of the equipment and reducing vibration and failure problems caused by complex shaft systems. However, the current coaxial hydraulic turbine equipment will vibrate during use, causing the equipment body to be unstable, affecting the energy recovery effect. It lacks an effective stable fixing mechanism and a pre-filtration system. Impurities in the liquid cause damage to the internal parts of the equipment. In view of this, we propose a coaxial hydraulic turbine equipment with an energy recovery mechanism. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1 - Fig.11 , the present invention provides a technical solution: A coaxial hydraulic turbine device with an energy recovery mechanism comprises a rectangular frame 1, a body 2 is placed on the top of the rectangular frame 1, a bolt 3 passes through the bottom of the body 2, the bolt 3 passes through the top of the rectangular frame 1, a nut 4 is threadedly installed on the outer side of the bolt 3, and four groups of bolts 3 and nuts 4 are provided to make the body 2 more solid.

[0023] In one embodiment of the present invention, a recovery component 5 is arranged on the outside of the rectangular frame 1, and the recovery component 5 includes a liquid inlet end 51. The liquid inlet end 51 is arranged at one end of the body 2. In addition, two groups of liquid inlet ends 51 are arranged, and the two groups of liquid inlet ends 51 are respectively located at both ends of the body 2. One end of a liquid inlet Y-shaped tube 52 is fixedly installed on the top of the liquid inlet end 51, and the other end of the liquid inlet Y-shaped tube 52 is fixedly connected to one end of a liquid inlet pipe 53. A pump 54, a flow meter 55 and a first stop valve 56 are arranged on the liquid inlet pipe 53. The other end of the liquid inlet pipe 53 is fixedly connected to one end of an auxiliary pipe 57, and a branch pipe 58 is fixedly installed on the auxiliary pipe 57. A second stop valve 59 is arranged on the branch pipe 58. An axle seat 510 is fixedly installed on the outside of the body 2, and a sealed bearing 5 is fixedly installed on the inside of the body 2. 11. A rotating shaft 512 is fixedly installed on the inner side of the sealed bearing 511, and the rotating shaft 512 is rotatably installed on the inner side of the shaft seat 510. In addition, two groups of the shaft seat 510 and the sealed bearing 511 are provided, so that the rotating shaft 512 can rotate more stably. An impeller 513 is fixedly installed on the outer side of the rotating shaft 512, and an output shaft 514 is fixedly installed on the side of the rotating shaft 512 close to the liquid inlet end 51. A disc 515 is fixedly installed inside the body 2, and the rotating shaft 512 passes through the center of the disc 515. A short groove 516 and a long groove 517 are respectively provided at both ends of the disc 515. A liquid outlet 518 is provided on the side of the body 2 away from the liquid inlet end 51, and a liquid outlet Y-shaped tube 519 is fixedly installed on the top of the liquid outlet end 518, and the top of the liquid outlet Y-shaped tube 519 is connected to an external collection device.

[0024] In this embodiment, when the entire device starts to run, the pump 54 is first started, and the pump 54 starts to work to generate power to transport the liquid that needs to be energy recovered to the inside of the device. The liquid first reaches the liquid inlet end 51, and then the liquid passes through the liquid inlet Y-shaped tube 52. One end of the liquid inlet Y-shaped tube 52 is fixedly connected to the top of the liquid inlet end 51, and the other end is connected to the liquid inlet pipe 53, which plays a role in guiding and diverting the liquid, ensuring that the liquid enters the inside of the body 2 smoothly. The flow meter 55 monitors the flow of the liquid in real time and provides the operator with accurate data on the flow state of the liquid, so as to better understand the operation of the equipment. The first stop valve 56 is used to control the opening and closing of the liquid inlet pipe 53. Only when the first stop valve 56 is opened, the liquid can continue to flow smoothly through the liquid inlet pipe 53. At the same time, the second stop valve 59 is used to control the opening and closing of the branch pipe 58. When it is necessary to input liquid for energy recovery into the body 2, the first stop valve 56 is opened, and the second stop valve 59 is closed, and the liquid flows to the inside of the body 2 and enters. The liquid entering the body 2 will flow through the disc 515. The two ends of the disc 515 are respectively provided with a short groove 516 and a long groove 517. The openings of the two grooves are different in size. When the liquid passes through the two grooves with different openings, the flow rates at the two ends of the impeller 513 will be different, forming a flow difference. This flow difference will produce different forces on the impeller 513, thereby driving the impeller 513 to rotate. The rotation of the impeller 513 will drive the rotating shaft 512 to rotate. The rotating shaft 512 is rotatably installed on the inner side of the shaft seat 510, and There are two groups of shaft seats 510 and sealed bearings 511. These two groups of structures can ensure that the rotation of the rotating shaft 512 is more stable and reduce shaking and friction during the rotation process. As the rotating shaft 512 rotates, the output shaft 514 also rotates, thereby successfully converting the flow potential energy of the liquid into the rotational energy of the shaft, thereby achieving the purpose of energy recovery. The liquid after energy recovery flows out from the liquid outlet 518, and the liquid outlet Y-shaped tube 519 transports the discharged liquid to a designated collection location for subsequent processing or reuse.

[0025] In one embodiment of the present invention, a fixing assembly 6 is provided at the top of the rectangular frame 1, and the fixing assembly 6 includes a slide rail 61. The slide rail 61 is fixedly installed on the top of the rectangular frame 1, and the two ends of the threaded rod 62 are rotatably installed on the inner side of the top of the slide rail 61, and a knob 63 is fixedly installed on the outer side of the threaded rod 62. A Z-shaped block 64 is threadedly installed on the outer side of the threaded rod 62, and a slider 65 is fixedly installed on one side of the Z-shaped block 64. The slider 65 is slidably installed on the slide rail 61. In addition, a fixing rod is fixedly installed on the other side of the Z-shaped block 64. 66, a ring 67 is rotatably installed on the outer side of the fixed rod 66, a moving block 68 is fixedly installed on the outer side of the ring 67, a roller 69 is rotatably installed on the inner side of the moving block 68, and a limiting rod 610 is fixedly installed on the bottom of the moving block 68. In addition, the slide rail 61, the threaded rod 62, the knob 63, the Z-shaped block 64, the slider 65, the fixed rod 66 and the ring 67 are arranged in four groups, and the moving block 68, the roller 69 and the limiting rod 610 on the single group of rings 67 are arranged in two groups, so that the body 2 is more solid.

[0026] In this embodiment, in order to ensure that the recovery component 5 can stably perform energy recovery work, the body 2 needs to be firmly fixed. During operation, the knob 63 is turned, and the turning of the knob 63 will drive the threaded rod 62 to rotate. When the threaded rod 62 rotates, the Z-shaped block 64 will move along the axial direction of the threaded rod 62 under the action of the threaded rod 62. The movement of the Z-shaped block 64 will drive the slider 65 to slide synchronously on the slide rail 61. At the same time, the fixed rod 66 will move with the movement of the Z-shaped block 64, and the ring 67 will also move accordingly with the movement of the fixed rod 66. When the moving block 68 drives the roller 69 to approach the outer side of the bottom end of the body 2, the roller 69 will contact the surface of the body 2, so that the roller 69 will exert a certain clamping force on the body 2, thereby firmly fixing the body 2. The function of the limit rod 610 is to restrict the rotation range of the ring 67. When the ring 67 has a tendency to rotate during the movement or under the influence of external force, the limit rod 610 will limit its rotation range to prevent the ring 67 from excessively rotating and affecting the fixing effect on the body 2, thereby ensuring that the recovery component 5 can better perform energy recovery work.

[0027] In one embodiment of the present invention, a filter assembly 7 is arranged on the outside of the machine body 2, and the filter assembly 7 includes a filter barrel 71, the other end of the auxiliary pipe 57 is fixedly installed on the arc-shaped side wall of the filter barrel 71, a support frame 72 is fixedly installed on the outside of the bottom end of the filter barrel 71, a top cover 73 is clamped on the top of the filter barrel 71, a glass window 74 is fixedly installed on the inside of the top cover 73, a bottom cover 75 is fixedly installed on the bottom of the filter barrel 71, a main pipe 76 is fixedly installed on the arc-shaped side wall of the filter barrel 71, a third stop valve 77 is arranged on the main pipe 76, a slave pipe 78 is fixedly installed on the outside of the main pipe 76, a conical cover 79 is fixedly installed on the top of the slave pipe 78, a bottom pipe 710 is fixedly installed on the outside of the auxiliary pipe 57, an arc-shaped filter cover 711 is clamped on the inside of the bottom end of the filter barrel 71, and the bottom pipe 710 penetrates the arc-shaped filter cover 711. In addition, the bottom of the bottom cover 75 is fixed A base frame 712 is installed, and a servo motor 713 is fixedly installed on the inner side of the base frame 712. A rotating rod 714 is fixedly installed on the output end of the servo motor 713. The rotating rod 714 is fixedly installed on the inner side of the center bearing 715, and the center bearing 715 is fixedly installed on the inner side of the center of the bottom cover 75. An arc plate 716 is fixedly installed on the outer side of the bottom end of the rotating rod 714. Three groups of arc plates 716 are provided, so as to better clean the inside of the filter barrel 71. In addition, the top of the rotating rod 714 is fixedly connected to the bottom center of the top plate 717, and a top rod 718 is fixedly installed on the top of the top plate 717. An arc scraper 719 is fixedly installed on the top of the top rod 718. The outer side of the arc scraper 719 slides and fits the bottom end of the arc filter cover 711. Two groups of top rod 718 and arc scraper 719 are provided, so as to have a better cleaning effect on the arc filter cover 711.

[0028] In this embodiment, before the liquid that needs energy recovery enters the body 2, it needs to be filtered first. The liquid first passes through the main pipe 76. The main pipe 76 is provided with a third stop valve 77. The third stop valve 77 is used to control the flow of the liquid in the main pipe 76. Only when the third stop valve 77 is opened, the liquid can pass through the main pipe 76. The conical cover 79 can guide the liquid to enter the filter barrel 71 evenly. The support frame 72 plays a role in supporting the filter barrel 71, so that the filter barrel 71 is placed more firmly and stably. After the liquid enters the filter barrel 71, it will be filtered through the arc filter cover 711. The arc filter cover 711 can block impurities and particles in the liquid, ensuring that the liquid entering the body 2 is purer and preventing impurities from damaging the internal parts of the equipment. The filtered liquid passes through the bottom pipe 710, and the bottom pipe 710 penetrates the arc filter cover 711 to transport the filtered liquid to the auxiliary pipe 57, and then enters the body 2. In order to ensure the filtering effect of the filter assembly 7, it is necessary to clean the arc filter cover 711 regularly. When the equipment is not performing energy recovery, the first stop valve 56 is closed and the second stop valve 59 is opened. At this time, the servo motor 713 on the base frame 712 is started, and the central bearing 715 is cooperated to ensure the stability of the rotating rod 714 during rotation. When the rotating rod 714 rotates, the arc plate 716 will rotate accordingly to better clean the inside of the filter barrel 71. At the same time, as the rotating rod 714 rotates, the arc scraper 719 will slide and rotate at the bottom end of the arc filter cover 711 to scrape and clean the impurities attached to the bottom end of the arc filter cover 711, thereby maintaining the good filtering performance of the arc filter cover 711 and ensuring better operation of the turbine equipment body. In addition, through the top cover 73, the glass window 74 and the bottom cover 75, the operator can easily observe and repair the parts inside the filter barrel 71 to ensure the normal operation and maintenance of the equipment.
