Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a power plant chemical online instrumentation wastewater discharge flow regulation device. Background Technology

[0002] Power plant chemistry focuses on the application and management of chemicals in the power industry, covering multiple aspects such as fuel analysis, water treatment, and corrosion protection. It ensures the safe and stable operation of power plant equipment and improves power generation efficiency and reduces environmental pollution through chemical means. Currently, in the process of transporting wastewater from power plants, online instrumentation wastewater discharge flow regulation devices are required to control the discharge volume of wastewater according to the wastewater treatment rate.

[0003] Chinese patent CN215462545U discloses a flow regulation mechanism for a sewage discharge system, including a flow meter, a scale, an adjustment component, and an oscillation structure. The scale is embedded on one side of the flow meter, and the adjustment component is installed on the bottom side of the flow meter. The adjustment component, when operated by a motor, drives a gear to rotate, enabling the torsion of a gear disc. The gear disc rotates with the cooperation of a positioning pin. The flow guide holes inside the gear disc are misaligned with the flow guide holes inside the baffle to control the flow rate. The inflow of water into the flow meter is constant. By observing the water storage in the flow meter according to the scale, the drainage flow can be regulated. The oscillation structure, operated by a vibrating motor and connected by a connecting rod, allows for relative lifting and lowering of the oscillating sleeve. During this lifting and lowering process, the water surface is oscillated, generating water waves that propel debris outwards, reducing debris around the filter balls and preventing them from clogging the filter balls, thus enabling stable and continuous drainage.

[0004] Although the aforementioned patent can regulate the discharge flow of sewage through staggered guide holes, in actual use, the small diameter of the guide holes reduces the maximum drainage capacity of the drain pipe. When rapid sewage discharge is required, the low drainage capacity makes the sewage discharge process time-consuming, affecting the sewage treatment efficiency. Furthermore, impurities and dirt in the sewage can easily clog the guide holes, causing them to accumulate, increasing the burden on the pipeline, and making it unsuitable for use. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned shortcomings by providing a power plant chemical online instrument sewage discharge flow regulation device. This device solves the problem that existing power plant chemical online instrument sewage discharge flow regulation devices regulate flow through staggered guide holes, resulting in a smaller maximum drainage capacity of the drainage pipe. Consequently, they cannot quickly carry out drainage work when emergency drainage is needed, increasing the burden on the pipeline.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A power plant chemical online instrumentation sewage discharge flow regulation device includes a regulating pipe, an automatic flow regulation component, and an anti-clogging component, characterized in that: both ends of the regulating pipe are connected to a conveying pipe, and a flow meter is installed on the regulating pipe;

[0008] The automatic flow regulation component includes a limiting shell, the top of which is fixedly connected to a regulating tube. A limiting rod is provided inside the limiting shell, and the right end of the limiting rod penetrates the limiting shell and is fixedly connected to a mounting bracket. An electric cylinder is fixedly connected to the inner cavity of the mounting bracket. An adjusting rod is driven by the output end of the electric cylinder. One end of the adjusting rod extends into the regulating tube and is fixedly connected to a sealing plug. An adjusting sleeve, which isolates the regulating tube, is fixedly connected inside the regulating tube. One end of the adjusting sleeve has a funnel-shaped channel facing the sealing plug, and the other end of the adjusting sleeve has a connecting channel communicating with the funnel-shaped channel. The shape of the funnel-shaped channel is adapted to the sealing plug. The electric cylinder drives the sealing plug to extend into or out of the funnel-shaped channel via the adjusting rod.

[0009] The anti-blocking component includes a control housing, the bottom of which is fixedly connected to an adjusting pipe. A rotary motor is fixedly connected inside the control housing, and the output end of the rotary motor drives a drive disk. A gear is provided on the outer arc surface of the drive disk. A unblocking rod is provided on one side of the adjusting pipe. One end of the unblocking rod is movably inserted into the adjusting pipe, and the other end is movably inserted through the control housing and is provided with teeth. The teeth mesh with the gear, and a reset mechanism is installed on the unblocking rod.

[0010] Furthermore, the unblocking rod is an inverted triangle shape, with a pointed cone at the lower transverse end and teeth located on the upper transverse part.

[0011] Furthermore, the reset mechanism includes a baffle fixed to the lower transverse part of the rod and a spring sleeved on the lower transverse part of the rod, with the beginning and end of the spring connected to the baffle and the adjusting tube, respectively.

[0012] Furthermore, a slide is fixedly connected to the bottom of the inner cavity of the control housing, a slider is slidably connected to the inner cavity of the slide, and the top of the slider is fixedly connected to the unblocking rod.

[0013] Furthermore, a limiting sleeve is slidably connected to the surface of the limiting rod, and the top and bottom of the limiting sleeve are fixedly connected to the inner wall of the limiting shell.

[0014] Furthermore, the right end of the regulating tube is fixedly connected to an regulating seat that works with the regulating rod, and a sealing ring is provided inside the regulating seat.

[0015] Furthermore, a limiting plate is fixedly connected to the left end of the limiting rod.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up an automatic flow regulation component, the flow rate of the regulating pipe can be automatically controlled. When rapid drainage is required, its minimal impact on the drainage volume of the regulating pipe allows sewage in the pipe to be quickly discharged into the treatment equipment, reducing the burden on the pipe. The electric cylinder adjusts the position of the sealing plug via the adjusting rod, allowing the sealing plug to extend into or out of the funnel-shaped channel, changing the gap between the sealing plug and the funnel-shaped channel, thereby regulating the amount of water passing through the funnel-shaped channel. This automatic adjustment method is convenient for operators to use and has minimal impact on the drainage volume of the regulating pipe, enabling rapid sewage discharge.

[0018] 2. By setting up anti-clogging components, the regulating sleeve inside the regulating pipe can be prevented from becoming clogged. When impurities and dirt in the sewage clog the connecting channel and the funnel-shaped channel, the rotary motor drives the drive disc to rotate, and the gears and teeth work together to control the movement of the unblocking rod. When the gears and teeth no longer mesh, the unblocking rod is reset by the reset mechanism. The unblocking rod moves back and forth continuously to clear the inner cavity of the regulating sleeve in the regulating pipe, pushing away the clogged impurities and ensuring that the sewage can be discharged normally.

[0025] Example 1:

[0026] Please see Figure 1-5A power plant chemical online instrument sewage discharge flow regulation device includes a regulating pipe 1, an automatic flow regulation component 4, and an anti-clogging component 5. The device is characterized in that: both ends of the regulating pipe 1 are connected to a conveying pipe 2, and a flow meter 3 is installed on the regulating pipe 1.

[0027] The automatic flow regulation component 4 includes a limiting shell 41, the top of which is fixedly connected to the regulating pipe 1. A limiting rod 42 is provided inside the limiting shell 41. The right end of the limiting rod 42 passes through the limiting shell 41 and is fixedly connected to a mounting bracket 43. An electric cylinder 44 is fixedly connected to the inner cavity of the mounting bracket 43. An regulating rod 45 is driven by the output end of the electric cylinder 44. One end of the regulating rod 45 extends into the regulating pipe 1 and is fixedly connected to a sealing plug 46. An regulating sleeve 4, which isolates the regulating pipe 1, is fixedly connected inside the regulating pipe 1. 7. One end of the adjusting sleeve 47 is provided with a funnel-shaped channel facing the sealing plug 46, and the other end of the adjusting sleeve 47 is provided with a connecting channel that connects to the funnel-shaped channel. The shape of the funnel-shaped channel is adapted to the sealing plug 46. The electric cylinder 44 drives the sealing plug 46 to extend into or out of the funnel-shaped channel through the adjusting rod 45. In use, the electric cylinder 44 drives the sealing plug 46 to extend into or out of the funnel-shaped channel through the adjusting rod 45, thereby changing the gap between the sealing plug 46 and the funnel-shaped channel, thereby adjusting the amount of water passing through the funnel-shaped channel.

[0028] The anti-blocking component 5 includes a control housing 51, the bottom of which is fixedly connected to the regulating pipe 1. A rotary motor 52 is fixedly connected inside the control housing 51. The output end of the rotary motor 52 drives a drive disk 53. A gear is provided on the outer arc surface of the drive disk 53. A clearing rod 54 is provided on one side of the regulating pipe 1. One end of the clearing rod 54 is movably inserted into the regulating pipe 1, and the other end is movably inserted through the control housing 51 and is provided with teeth 55. The teeth 55 mesh with the gear. A reset mechanism 56 is installed on the clearing rod 54. In use, the rotary motor 52 drives the drive disk 53 to rotate. During the meshing process of the gear and teeth 55, the end of the clearing rod 54 is inserted into the connecting channel and the funnel-shaped channel to clear the connecting channel and the funnel-shaped channel.

[0029] Please see Figure 1-5 The unblocking rod 54 is a C-shaped rod body, with a pointed cone at the lower horizontal end of the rod body, and the teeth 55 are provided on the upper horizontal part; in this embodiment, the rotary motor 52 drives the drive disk 53 to rotate, and during the meshing of the gear and the teeth 55, the pointed cone at the lower horizontal end of the rod body penetrates into the connecting channel and the funnel-shaped channel to unblock the connecting channel and the funnel-shaped channel.

[0030] Please see Figure 1-5The reset mechanism 56 includes a baffle 561 fixed to the lower transverse part of the rod and a spring 562 sleeved on the lower transverse part of the rod. The beginning and end of the spring 562 are respectively connected to the baffle 561 and the adjusting tube 1. In this embodiment, the rotary motor 52 drives the drive disk 53 to rotate. During the meshing of the gear and the teeth 55, the pointed cone at the end of the lower transverse part of the rod penetrates into the connecting channel and the funnel-shaped channel to clear the connecting channel and the funnel-shaped channel. At this time, the spring 562 is compressed. When the drive disk 53 rotates until the gear and the teeth 55 no longer mesh, the rod is reset by the restoring force of the spring 562.

[0031] Please see Figure 1-5 The bottom of the inner cavity of the control housing 51 is fixedly connected to a slide rail, and a slider is slidably connected to the inner cavity of the slide rail. The top of the slider is fixedly connected to the unblocking rod 54. In this embodiment, the sliding limit of the unblocking rod 54 can be achieved by the slider sliding along the slide rail.

[0032] Please see Figure 1-5 The limiting rod 42 is slidably connected to the limiting sleeve 6, and the top and bottom of the limiting sleeve 6 are fixedly connected to the inner wall of the limiting shell 41. In this embodiment, the limiting rod 42 can be further fixed by the limiting sleeve 6.

[0033] Please see Figure 1-5 The right end of the regulating pipe 1 is fixedly connected to an regulating seat 7 that works with the regulating rod 45. A sealing ring 8 is provided inside the regulating seat 7. In this embodiment, the sealing ring 8 increases the sealing between the regulating seat 7 and the regulating rod 45, preventing sewage from overflowing from the regulating pipe 1 and polluting the surrounding environment.

[0034] Please see Figure 1-5The left end of the limiting rod 42 is fixedly connected to the limiting plate 9. Working principle: The flow meter 3 records the flow rate of sewage transported inside the regulating pipe 1 and transmits the recorded data to the operator's terminal device for statistical analysis. The electric cylinder 44 drives the sealing plug 46 to extend or retract into the funnel-shaped channel via the adjusting rod 45, changing the gap between the sealing plug 46 and the funnel-shaped channel, thereby adjusting the amount of water passing through the funnel-shaped channel. When rapid sewage discharge is required, the electric cylinder 44 drives the sealing plug 46 to move outside the funnel-shaped channel, allowing the sewage to pass smoothly through the regulating sleeve 47 without being obstructed by the sealing plug 46, ensuring that the regulating pipe 1 can discharge sewage at its maximum capacity. The water discharge process avoids the accumulation of sewage and the resulting burden on the pipeline. During the sewage discharge process, when the flow meter 3 detects a decrease or complete cessation of water flow from the regulating pipe 1, the rotary motor 52 is activated. The rotary motor 52 drives the drive disc 53 to rotate. During the meshing of the gear and teeth 55, the pointed cone at the lower transverse end of the rod penetrates the connecting channel and the funnel-shaped channel to clear the blockage. At this time, the spring 562 is compressed. When the drive disc 53 rotates until the gear and teeth 55 no longer mesh, the restoring force of the spring 562 drives the rod to reset, preventing impurities from clogging it and ensuring that sewage can be discharged normally.
