Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] Embodiment one: please refer to Figure 1 , Figure 2The application discloses an acetylene process supernatant conveying pipeline assembly, which comprises a concentration pool 1, a cooling tower 2, a buffer pool 3 and an acetylene process generator 4, the cooling tower 2 is located at the right side of the concentration pool 1 and is fixedly connected with the concentration pool 1 through an injection pipe 5, an overflow hole is formed in the top of the inner wall of the cooling tower 2, the cooling tower 2 and the buffer pool 3 are fixedly connected through an overflow pipe 6, one end of the overflow pipe 6 is connected with the overflow hole, the acetylene process generator 4 is located at the right side of the cooling tower 2, and a self-flow pipe 7 for autonomously conveying supernatant is fixedly installed between the cooling tower 2 and the acetylene process generator 4.
[0025] The outer wall of the self-flow pipe 7 is fixedly installed with an adjusting structure for controlling the flow of the pipeline, and the inner cavity of the injection pipe 5 is fixedly installed with a cleaning structure for avoiding pipeline blockage.
[0026] Specifically, the two ends of the injection pipe 5 are fixedly connected with the concentration pool 1 and the cooling tower 2 respectively, the buffer pool 3 is used as a water level adjusting pool of the cooling tower 2, when the system water level fluctuates and the liquid level is too high, the supernatant in the cooling tower 2 automatically overflows from the overflow hole to the buffer pool 3 through the overflow pipe 6, so that the overflow of supernatant caused by the high liquid level of the cooling pool is effectively prevented.
[0027] More specifically, there is a high difference between the cooling tower 2 and the acetylene process generator 4, the cooling tower 2 is higher than the acetylene process generator 4, the inner wall of the cooling tower 2 is fixedly installed with a sensor for sensing the water level in the cooling tower 2, when the sensor senses that the water level of the cooling tower 2 reaches the height of the overflow hole while the concentration pool 1 is in the state of overflow, the adjusting structure is driven to make the self-flow pipe 7 open the flow state, the supernatant in the cooling tower 2 automatically flows into the acetylene process generator 4 by means of the difference in height and siphoning, so that the equipment operation is reduced and the power consumption is reduced, and the acetylene process generator 4 is provided with two groups, and the bottom ends of the self-flow pipes 7 are fixedly connected with the two groups of acetylene process generators 4 respectively.
[0028] Please refer to Figure 3 、 Figure 4 The adjusting structure comprises a valve body 701, the valve body 701 is fixedly sleeved on the outer wall of the self-flow pipe 7, a curved rotating rod 702 is rotatably installed in the inner cavity of the valve body 701 through a bearing, the outer wall of the curved rotating rod 702 is fixedly connected with a rotating block 703, the outer wall of the rotating block 703 is rotatably installed with a transmission rod 704 on both sides through a pin shaft, and the distal ends of the two transmission rods 704 are fixedly installed with a throttling plug 705 for adjusting the flow.
[0029] Specifically, the upper and lower ends of the valve body 701 are respectively provided with a liquid inlet end and a liquid outlet end, and a tapered groove is formed in the liquid inlet end and the liquid outlet end. The tapered groove in the liquid inlet end is used to guide the liquid to enter the valve body 701 smoothly, reduce the impact and turbulence when the liquid enters, and make the liquid be distributed uniformly in the cavity of the valve body 701. The tapered groove in the liquid outlet end helps to guide the adjusted liquid to flow out of the valve body 701 smoothly, avoiding problems such as poor liquid flow or excessive pressure loss caused by unreasonable outlet shape.
[0030] More specifically, the two groups of throttle plugs 705 are both conical blocks and are matched with the tapered grooves. By rotating the curved rotating rod 702, the transmission rod 704 drives the two groups of throttle plugs 705 to slide up and down in the tapered grooves. When the throttle plug 705 moves to the liquid outlet end and enters the narrower part of the tapered groove, the movement of the throttle plug 705 reduces the flow space of the flow passage, thereby causing the flow to decrease. Because the flow passage becomes narrower, the liquid flow rate increases. Conversely, when the throttle plug 705 moves to the liquid inlet end and enters the wider part of the tapered groove, the movement of the throttle plug 705 increases the effective flow space of the flow passage, causing the flow to increase. Because the flow passage becomes wider, the liquid flow rate decreases. By moving the throttle plug 705, the liquid flow and flow rate can be accurately controlled, the pressure in the pipeline is reduced, and the safety of the equipment is enhanced.
[0031] The outer walls of the two groups of throttle plugs 705 are both fixedly provided with a sealing silica gel ring 708, which effectively enhances the airtightness of the valve body 701.
[0032] The outer wall of the valve body 701 is fixedly connected with an outer cover 706. The inner cavity of the outer cover 706 is fixedly installed with a motor 707 for providing rotating power for the curved rotating rod 702. The output end of the motor 707 is fixedly connected with one end of the curved rotating rod 702. The outer wall of the valve body 701 is fixedly installed with a detector 709 for detecting the flow rate.
[0033] Embodiment two: please refer to Figure 5 , based on the basis of embodiment 1, the cleaning structure includes a filter screen 506 fixedly installed in the inner cavity of the injection pipe 5. The inner cavity of the filter screen 506 is installed with a screw rod 501. The outer wall of the screw rod 501 is threadedly provided with a rotating shaft 502. The outer wall of the rotating shaft 502 is fixedly provided with a fixed sleeve 503. The outer wall of the fixed sleeve 503 is fixedly installed with a cleaning brush 504 for removing dirt. The outer wall of the rotating shaft 502 is fixedly provided with a cleaning shovel 505 for removing dirt, and the cleaning shovel 505 is fixedly connected with the fixed sleeve 503.
[0034] Specifically, the two sides of the screw rod 501 are both rotatably connected with a fixed frame 507 through bearings, and the fixed frame 507 is fixedly located in the inner cavity of the filter screen 506.
[0035] One end of the outer wall of the screw rod 501 is fixedly sleeved with a vortex blade 508 for driving the screw rod 501 to rotate forward, and the other end of the outer wall of the screw rod 501 is rotatably installed with a positioning sleeve 509, the inner cavity of the positioning sleeve 509 is fixedly installed with a torsional spring for driving the screw rod 501 to rotate reversely, and the torsional spring is fixedly connected with one end of the screw rod 501;
[0036] Specifically, when the liquid passes through the injection pipe 5, the filter screen 506 intercepts dirt and impurities, the vortex blade 508 is driven to rotate the screw rod 501 forward by the impact force of the liquid flow, so that the rotating shaft 502 moves along the screw rod 501, and the limiting rod fixedly installed on the outer wall of the rotating shaft 502 limits the rotating shaft 502 to avoid the phenomenon of self-rotation of the rotating shaft 502, and the inner wall of the filter screen 506 is provided with a sliding groove for providing sliding of the limiting rod, and one end of the limiting rod is located in the sliding groove;
[0037] At the same time, in this process, when the screw rod 501 rotates, the torsional spring rotates to store energy, and when the rotating shaft 502 moves to be attached to the positioning sleeve 509, the torsional spring is fully charged, and then the torsional spring is discharged to drive the screw rod 501 to rotate reversely, so as to drive the rotating shaft 502 to rotate and move towards the vortex blade 508;
[0038] Notably, when the torsional spring is fully discharged, the force driving the screw rod 501 to rotate reversely gradually decreases, and due to the curved angle of the vortex blade 508, the vortex blade 508 can be driven to rotate the screw rod 501 forward again under the push of the water flow;
[0039] More specifically, the cleaning brush 504 is uniformly distributed on the outer wall of the fixed sleeve pipe 503 in a spiral shape, and when the fixed sleeve pipe 503 moves left and right along the axial direction, the cleaning brush 504 can comprehensively and carefully clean the inner wall of the filter screen 506, loosen the attached dirt, and cooperate with the cleaning shovel 505 to tightly attach to the inner wall of the filter screen 506 to scrape off stubborn dirt. Due to the spiral structure of the cleaning brush 504, the dirt cleaned and scraped off can be discharged along the gap between the cleaning brushes 504 arranged in a spiral under the scouring action of the water flow, effectively avoiding dirt accumulation and ensuring that the filter screen 506 always maintains good filtering performance;
[0040] The two ends of the rotating shaft 502 are fixedly installed with a buffer pad 510 for reducing collision damage, and the bottom end of the injection pipe 5 is fixedly installed with a collecting pipe 511 for collecting dirt, and one side of the collecting pipe 511 is fixedly connected with a discharge port for discharging dirt.
[0041] Please refer to Figure 1 , Figure 2The cooling tower 2 is fixedly installed with a clear liquid pipe 8 near one end of the acetylene process generator 4, and the bottom end of the clear liquid pipe 8 is fixedly connected with the top end of the acetylene process generator 4, and the outer wall of the clear liquid pipe 8 is fixedly installed with a clear liquid pump 9, when the self-flow of the supernatant is not smooth or the temperature of the supernatant is high, the supernatant is pumped out by the clear liquid pump 9 and supplied to the acetylene process generator 4 through the clear liquid pipe 8;
[0042] The bottom end of the concentration tank 1 is fixedly installed with a support frame 10 for supporting, one side of the support frame 10 is installed with a support platform 11, and the cooling tower 2 and the buffer tank 3 are both fixedly installed on the upper surface of the support platform 11.
[0043] The working principle of the utility model is:
[0044] Firstly, the supernatant in the concentration tank 1 is overflowed into the cooling tower 2 through the injection pipe 5, the dirt and impurities in the clear liquid are intercepted by the filter screen 506 in the injection pipe 5, the liquid flow impacts the vortex paddle 508, drives the screw rod 501 to rotate forward, moves the rotating shaft 502 along the screw rod 501, and stores the torsional spring at the same time, when the rotating shaft 502 is attached to the positioning sleeve 509, the torsional spring releases the force to drive the screw rod 501 to rotate reversely, drives the rotating shaft 502 to move reversely, makes the cleaning shovel 505 and the cleaning brush 504 move axially in the filter screen 506, uses the cleaning shovel 505 to shovel the dirt, and uses the cleaning brush 504 to remove the impurities, realizes the automatic cleaning of the filter screen 506, and the cleaned dirt is washed to the collecting pipe 511 for collection by the liquid;
[0045] Then, the cooling tower 2 and the buffer tank 3 are connected through the overflow pipe 6, when the liquid level of the cooling tower 2 is too high due to the water quantity fluctuation of the system, the supernatant is automatically overflowed from the overflow hole to the buffer tank 3 through the overflow pipe 6, prevents the clear liquid from flowing out, and there is a high difference between the cooling tower 2 and the acetylene process generator 4, the cooling tower 2 is higher than the acetylene process generator 4, when the water level of the cooling tower 2 reaches the height of the overflow hole, the sensor senses the driving adjusting structure, starts the motor 707 to drive the curved rotating rod 702 to rotate, the curved rotating rod 702 drives the rotating block 703 to rotate when rotating, and then controls the transmission rod 704 to drive two groups of throttle plugs 705 to slide in the liquid inlet end and the liquid outlet end of the valve body 701 respectively, so that the self-flow pipe 7 is opened, the supernatant in the cooling tower 2 is automatically flowed into the acetylene process generator 4 by using the difference siphon, and if the self-flow of the supernatant is not smooth or the temperature is high, the supernatant is pumped out by the clear liquid pump 9 on the clear liquid pipe 8 and supplied to the acetylene process generator 4;
[0046] Meanwhile, the flow of the valve body 701 can be controlled according to actual requirements by controlling the positions of the two groups of throttle plugs 705 in the taper grooves of the liquid inlet end and the liquid outlet end respectively, when the throttle plug 705 moves to the narrow part of the liquid outlet end taper groove, the effective cross-sectional area of the flow channel decreases, the flow decreases, and the flow rate increases; on the contrary, when it moves to the wide part of the liquid inlet end taper groove, the effective cross-sectional area of the flow channel increases, the flow increases, and the flow rate decreases, so as to accurately control the flow and the flow rate, and reduce the pressure in the pipeline.
[0047] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
