Description

Technical Field

[0001] This utility model belongs to the field of wastewater online monitoring technology, specifically a quick-release wastewater online monitoring equipment maintenance device. Background Technology

[0002] In the field of online wastewater monitoring, in order to ensure the stable operation of online monitoring equipment and avoid damage to the equipment caused by large-diameter impurities in the wastewater pipeline, a primary filtration device is usually installed at the connection point between the online monitoring equipment and the wastewater pipeline to intercept large-diameter impurities in the wastewater.

[0003] In existing technologies, the filter structures used are easily clogged by impurities after prolonged immersion in the sewage environment. Since they are installed inside the connecting pipes, the entire connecting structure must be disassembled to clean the clogged impurities, which is not only cumbersome and time-consuming, but also seriously affects the continuity and efficiency of sewage monitoring.

[0004] Therefore, there is an urgent need to propose a quick-release maintenance device for online wastewater monitoring equipment to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a quick-release online wastewater monitoring equipment maintenance device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release online sewage monitoring equipment maintenance device, comprising a left valve body, a right valve body detachably installed on the right side of the left valve body, a mechanical seal structure installed on the top of the opposite side of the left and right valve bodies, a sealing mechanism slidably installed inside the mechanical seal structure, filter chambers respectively provided inside the left and right valve bodies, the two filter chambers being connected and connected, and filter holes being opened at the bottom of both filter chambers; wherein, the sealing mechanism includes a sealing shell, the sealing shell being located inside the left and right valve bodies and fitted onto the outside of the two connected filter chambers, a sliding rod installed on the top of the sealing shell, the sliding rod passing through the mechanical seal structure, and a top rod provided at the bottom of the inner side of the sealing shell, the top rod being located directly below the filter holes and matching the diameter of the filter holes.

[0007] Preferably, the left valve body is connected to an outlet pipe, which is used to connect to an online wastewater monitoring device. The outlet pipe ensures a stable connection between the left valve body and the online wastewater monitoring device, guaranteeing that the wastewater filtered through the filter chamber can accurately enter the monitoring device, providing a stable wastewater pathway for monitoring.

[0008] Preferably, a guide frame is provided at the bottom outer side of the slide rod. The guide frame is used to ensure stable vertical movement of the slide rod on the opposite side of the left and right valve bodies. The guide frame can limit the movement direction of the slide rod, prevent the slide rod from deviating during sliding, ensure that the sealing shell and push rod of the sealing mechanism always maintain accurate positions, and improve the reliability of sealing and impurity ejection.

[0009] Preferably, both the left and right valve bodies have grooves on opposite sides with embedded sealing rings, and both filter chambers have grooves on opposite sides with embedded sealing rings. The two sets of sealing rings enhance the sealing performance of the joint between the left and right valve bodies and the two filter chambers, effectively preventing sewage leakage from the joint gaps and avoiding leakage from affecting the surrounding environment or interfering with monitoring data.

[0010] Preferably, the top of the outer wall of the slide rod is provided with an external thread, and an adjusting nut is installed on the external thread. The adjusting nut is used to adjust the vertical height of the sealing shell in the left and right valve bodies. By rotating the adjusting nut in conjunction with the external thread, the vertical height of the sealing shell can be conveniently and accurately controlled, and the sealing of the liquid outlet channel and the ejection of impurities from the filter holes can be quickly achieved without disassembling the device, thus improving the ease of operation.

[0011] Preferably, the internal height of the sealing shell is greater than the height of the filter chamber, and the internal width of the sealing shell is the same as the width of the filter chamber. The greater internal height of the sealing shell provides ample space for the sealing shell to move vertically, ensuring the proper functioning of sealing and impurity removal. The same internal width as the filter chamber ensures a tight fit between the sealing shell and the filter chamber, preventing wastewater from flowing through the gaps and affecting the filtration effect.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model features a sealing mechanism that is slidably installed within a mechanical seal structure. The sealing shell of the sealing mechanism is fitted onto the outside of two filter chambers that are connected and aligned with the inner sides of the left and right valve bodies. The bottom of the sealing shell has a top rod that matches and is directly opposite the diameter of the filter holes at the bottom of the filter chamber, and the top has a sliding rod that passes through the mechanical seal structure. When it is necessary to clean the filter holes of the filter chamber, it is not necessary to disassemble the detachably connected left and right valve bodies. The top rod can be moved upward by sliding the sliding rod to directly push out the impurities blocking the filter holes. This effectively solves the problem that in the prior art, cleaning the blockage impurities requires disassembling the entire connection structure, which is cumbersome and time-consuming.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, this utility model provides a quick-release online sewage monitoring equipment maintenance device, including a left valve body 1, a right valve body 3, a sealing mechanism 2, a filter chamber 4, a filter hole 41, an outlet pipe 11, a guide frame 221, an adjusting nut, and a sealing ring; Both the left valve body 1 and the right valve body 3 are installed on the sewage pipe and are spliced ​​together along the pipe axis to form the pipe section; the left valve body 1 has a hollow structure and an independent filter chamber 4 is provided inside. The filter chamber 4 extends along the length of the left valve body 1 and has the same structure as the filter chamber 4 inside the right valve body 3. The left valve body 1 and the filter chamber 4 form an annular gap on opposite sides. This gap is connected to the liquid outlet pipe 11 that is connected to the side wall of the left valve body 1. The right end face of the left valve body 1 is attached to the left end face of the right valve body 3. The connection is detachable by bolts that are evenly distributed around the circumference. After splicing, the filter chamber 4 of the left valve body 1 and the filter chamber 4 of the right valve body 3 are connected. Sewage can flow along the pipe direction inside the two filter chambers 4 and can flow from the left side of the left valve body 1 to the right side of the right valve body 3. The mechanical seal structure is fixedly installed on the top area of ​​the opposite side of the left valve body 1 and the right valve body 3 by bolts. The mechanical seal structure is annular and has a vertically extending sliding channel reserved inside. The sealing mechanism 2 is slidably installed in the sliding channel. The bottom of the filter chambers 4 of the left valve body 1 and the right valve body 3 are provided with several filter holes 41. The filter holes 41 penetrate the bottom wall of the filter chamber 4 and are connected to the annular gap between the corresponding valve body and the filter chamber 4. The sealing mechanism 2 includes a sealing shell 21, a top rod 211 and a sliding rod 22. The sealing shell 21 is a hollow shell with openings at both ends. It is located inside the left valve body 1 and the right valve body 3 and is tightly fitted onto the outer walls of the two filter chambers 4 after they are connected. The outer walls of the sealing shell 21 do not contact the inner wall of the valve body and do not obstruct the flow of sewage in the annular gap. A slide rod 22 is fixedly installed at the center of the top end face of the sealing shell 21. The slide rod 22 extends upward in the vertical direction, passes through the sliding channel of the mechanical seal structure, and slides against the inner wall of the sliding channel. The bottom inner wall of the sealing shell 21 is integrally formed with a top rod 211 in the vertical direction. The number of top rods 211 is the same as the number of filter holes 41 at the bottom of the filter chamber 4. Each top rod 211 is located directly below the corresponding filter hole 41, and the outer wall of the top rod 211 is adapted to the inner wall of the filter hole 41.

[0017] like Figure 1 As shown, the outlet pipe 11 connected to the side wall of the left valve body 1 has one end connected to the annular gap between the left valve body 1 and the filter chamber 4, and the other end is provided with an interface for connecting the wastewater online monitoring equipment. The interface structure is adapted to the inlet of the wastewater online monitoring equipment. The connection between the outlet pipe 11 and the left valve body 1 is integrally formed or welded to ensure the connection is sealed and prevent sewage from leaking to the outside from the connection. The right valve body 3 has the same structure as the left valve body 1. It also has an annular gap inside that is opposite to the filter chamber 4, but it is not connected to the liquid outlet pipe 11. It only serves as part of the passage for sewage to flow in the filter chamber 4.

[0018] like Figure 2 and Figure 5 As shown, a guide frame 221 is fixedly installed in the bottom area of ​​the outer side wall of the slide rod 22. The guide frame 221 is a symmetrically arranged frame structure, with both ends extending to the inner walls of the left valve body 1 and the right valve body 3 respectively, and slidingly fitting against the inner walls of the left valve body 1 and the right valve body 3. The top area of ​​the outer wall of the slide rod 22 is provided with an external thread, and an adjusting nut is installed on the external thread. The adjusting nut is located above the mechanical seal structure, and the outer diameter of the adjusting nut is larger than the inner diameter of the sliding channel of the mechanical seal structure. By rotating the adjusting nut, the vertical position of the slide rod 22 can be restricted, thereby controlling the movement of the sealing shell 21 and the top rod 211. When the push rod 211 does not enter the filter hole 41, the filter hole 41 remains unobstructed. When the push rod 211 enters the filter hole 41, it can push out internal impurities.

[0019] like Figure 2 and Figure 3As shown, annular grooves extending circumferentially are respectively opened at the docking end faces of the left valve body 1 and the right valve body 3. A sealing ring is embedded in the annular groove. The thickness of the sealing ring is greater than the depth of the annular groove. After the left valve body 1 and the right valve body 3 are spliced ​​together, the sealing ring is squeezed and fits against the docking end face to achieve a seal at the valve body docking point and prevent sewage from leaking from the valve body docking seam to the outside. At the docking end faces of the two filter chambers 4, an annular groove extending in the circumferential direction is also provided. A sealing ring is embedded in the annular groove. The structure of the sealing ring is adapted to the annular groove of the docking end face of the filter chamber 4. After the filter chambers 4 are docked, the sealing ring fits tightly with the docking end face, thereby sealing the docking point of the filter chambers 4 and preventing sewage from flowing from the docking seam of the filter chambers 4 into the annular gap for filtration around the filter hole 41.

[0020] like Figure 2 and Figure 4 As shown, the internal height of the sealing shell 21 is greater than the overall height of the two filter chambers 4 after docking, which provides sufficient space for the sealing shell 21 to move up and down, ensuring that the top rod 211 can completely exit the filter hole 41 or completely enter the filter hole 41 to clear the blockage, and avoiding interference between the sealing shell 21 and the top or bottom of the filter chamber 4. The inner width of the sealing shell 21 is adapted to the outer width of the filter chamber 4, ensuring that the inner wall of the sealing shell 21 and the outer wall of the filter chamber 4 are tightly fitted, preventing sewage from flowing into the annular gap and around the filter hole 41 from the gap between the two, while not hindering the normal flow of sewage inside the filter chamber 4. At the bottom of the filter chambers 4 of the left valve body 1 and the right valve body 3, the filter holes 41 are evenly distributed along the length of the filter chamber 4 to ensure that when sewage flows through the filter chamber 4, it can enter the annular gap evenly through the filter holes 41, and avoid local impurities accumulating too quickly and causing the filter holes 41 to become blocked.

[0021] Working principle and usage process of this utility model: During normal filtration, sewage flows along the sewage pipe into the left side of the left valve body 1, enters the filter chamber 4 of the left valve body 1, then flows through the filter chamber 4 of the right valve body 3 which is connected to it, and is discharged through the sewage pipe connected to the right side of the right valve body 3. During the monitoring process, some large-diameter impurities in the wastewater were intercepted by the filter holes 41 at the bottom of the filter chamber 4. The impurities could not pass through the filter holes 41, and the wastewater that met the particle size requirements entered the annular gap between the left valve body 1 and the filter chamber 4 and the annular gap between the right valve body 3 and the filter chamber 4 through the filter holes 41. The sewage in the gap is collected into the annular gap of the left valve body 1, then flows into the outlet pipe 11, and finally enters the sewage online monitoring equipment to complete the monitoring; When the filter hole 41 becomes clogged due to the accumulation of impurities, and the flow rate of sewage through the filter hole 41 decreases, the adjusting nut at the top of the slide rod 22 is rotated clockwise. The adjusting nut moves downward along the external thread of the slide rod 22, squeezing the mechanical seal structure and driving the slide rod 22 to move vertically upward along the sliding channel. The slide bar 22 synchronously drives the sealing shell 21 to move upward, and the top rod 211 at the bottom of the inner side of the sealing shell 21 moves upward accordingly, extends into the corresponding filter hole 41, pushes out the impurities blocking the filter hole 41, and the impurities fall into the filter chamber 4 and flow away with the sewage. After the blockage is cleared, turn the adjusting nut counterclockwise. The adjusting nut moves upward along the external thread. Under the action of gravity, the slide rod 22 drives the sealing shell 21 and the top rod 211 to move vertically downward and reset. The top rod 211 completely exits the filter hole 41, the filter hole 41 is unobstructed, and the device returns to normal filtration state.
