Description

Technical Field

[0001] This utility model relates to the field of wastewater discharge technology, specifically to a wastewater treatment discharge detection device. Background Technology

[0002] With the advancement of industrialization and urbanization, the amount of sewage discharged has surged. If it is discharged directly without meeting the standards, it can easily cause environmental problems such as eutrophication and heavy metal pollution, threatening ecosystems and human health.

[0003] Before the detection work, a large number of bubbles may be attached to the surface of the sewage. The scattering effect of bubbles on light is similar to that of suspended solids, which will cause the detection value to be falsely high. The oxygen in the bubbles will dissolve into the water sample, resulting in the detection value being higher than the actual dissolved oxygen content of the water body, affecting the judgment of the oxygen supply status of the biochemical treatment process. Moreover, bubbles may enter the sensor, causing poor electrode contact, moisture in optical components, and shortening the equipment life. Therefore, we propose a discharge detection device for sewage treatment. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment discharge detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment discharge detection device, comprising a housing, support legs disposed at the bottom of the housing, and further comprising:

[0006] A puncture assembly, comprising a sliding plate slidably connected to the interior of a box in a horizontal direction, wherein rivets for puncturing air bubbles are evenly spaced at the bottom of the sliding plate, and the tips of the rivets are vertically downward.

[0007] A striking assembly includes a striking head fixedly connected to the side of a sliding plate. The striking head is adapted to the inner wall of the housing. Springs are symmetrically connected between the sliding plate and the inner wall of the housing. The springs are used to drive the sliding plate to reset. A connecting rope is connected to the center of the top of the sliding plate. A communicating hole is opened on the top of the housing. The connecting rope passes through and is slidably connected in the communicating hole. A limiting ball is fixedly connected to the end of the connecting rope away from the sliding plate. The diameter of the limiting ball is larger than the diameter of the communicating hole.

[0008] Furthermore, limit components are symmetrically arranged on both sides of the inner wall of the box near the sliding plate. The limit components include a limit groove opened in the inner wall of the box in the horizontal direction, a limit block is slidably connected in the limit groove, and the end of the limit block away from the limit groove is fixedly connected to the sliding plate.

[0009] The above technical solution is adopted: by setting a limiting component, the trajectory of the sliding plate during the movement is limited and supported.

[0010] Furthermore, a detection component is provided on one side of the box. The detection component includes a support plate fixedly connected to the outer wall of the box. A detector is fixedly installed on the top of the support plate. A sampling chamber is provided on the detector. A second conduit is connected between the lower side wall of the box and the sampling chamber. A solenoid valve is connected in series on the second conduit. The water inlet end of the second conduit extends to the lower part of the box.

[0011] The above technical solution involves setting up a detection component and opening a solenoid valve to guide the wastewater, after the bubbles have been eliminated, into the sampling chamber through a second conduit for detection.

[0012] Furthermore, a water inlet assembly is provided on the top of the tank. The water inlet assembly includes a first conduit connected to one side of the top of the tank. The inlet end of the first conduit is connected to a first water pump, and the outlet end of the first conduit extends into the tank and is positioned towards the inner wall of the tank.

[0014] Furthermore, a drainage assembly is provided on the side of the box near the bottom. The drainage assembly includes a drain pipe connected to the bottom of the box, a second water pump is connected in series on the drain pipe, and a manual valve is also provided on the drain pipe.

[0015] The above technical solution involves installing drainage components to discharge qualified wastewater through drainage pipes.

[0016] Furthermore, a filter screen is horizontally installed inside the housing, located directly above the puncture component, and the edge of the filter screen is fixedly connected to the inner sidewall of the housing.

[0017] The above technical solution involves setting up a filter screen to filter and block impurities and particulate matter in the wastewater, preventing them from affecting the test results.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting up a puncturing component and a striking component, bubbles on the surface of sewage are eliminated, avoiding falsely high values ​​caused by light scattering from bubbles. Dissolved oxygen detection will also not produce false positive results due to oxygen supply from bubbles. This solves the problems of existing technologies that cannot eliminate bubbles on the surface of sewage before detection, bubbles scattering light similarly to suspended matter, which can lead to falsely high detection values. Oxygen in bubbles can also dissolve into the water sample, causing the detection value to be higher than the actual dissolved oxygen content in the water, affecting the judgment of the oxygen supply status of the biochemical treatment process. Furthermore, bubbles may enter the sensor, causing poor electrode contact, moisture damage to optical components, and shortening the life of the equipment. Attached Figure Description

[0034] 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.

[0035] Example 1

[0036] like Figures 1-4 As shown, this utility model provides a technical solution: a wastewater treatment discharge detection device, including a housing 1, a support leg 2 disposed at the bottom of the housing 1, and further comprising:

[0037] The puncture component 3 includes a sliding plate 31 that is slidably connected to the inside of the box 1 in a horizontal direction. The bottom of the sliding plate 31 is evenly spaced with rivets 32 for puncturing air bubbles, and the tips of the rivets 32 are set vertically downward.

[0038] The striking assembly 4 includes a striking head 41 fixedly connected to the side of the sliding plate 31. The striking head 41 is adapted to the inner wall of the housing 1. A spring 42 is symmetrically connected between the sliding plate 31 and the inner wall of the housing 1. The spring 42 is used to drive the sliding plate 31 to reset. A connecting rope 43 is connected to the top center of the sliding plate 31. A connecting hole 45 is opened on the top of the housing 1. The connecting rope 43 passes through and is slidably connected in the connecting hole 45. A limiting ball 44 is fixedly connected to the end of the connecting rope 43 away from the sliding plate 31. The diameter of the limiting ball 44 is larger than the diameter of the connecting hole 45.

[0039] A filter screen 9 is horizontally installed inside the housing 1. The filter screen 9 is located directly above the puncture component 3, and the edge of the filter screen 9 is fixedly connected to the inner wall of the housing 1.

[0040] Specifically, when a large number of bubbles adhere to the surface of the sewage, pulling the limiting ball 44 causes the connecting rope 43 to slide on the connecting hole 45, thereby causing the sliding plate 31 and the rivet 32 ​​at the bottom to puncture the bubbles. During the movement, the sliding plate 31 will compress the spring 42. When the limiting ball 44 is released, the sliding plate 31 will automatically spring back to its original position by the elastic force of the spring 42 after it contracts. The striking head 41 on the sliding plate 31 will collide with the inner wall of the tank 1 to generate vibration, further eliminating the bubbles.

[0041] Example 2

[0042] Furthermore, such as Figure 2 and Figure 5As shown: A detection component 7 is provided on one side of the box 1. The detection component 7 includes a support plate 71 fixedly connected to the outer wall of the box 1. A detector 72 is fixedly installed on the top of the support plate 71. A sampling chamber 73 is provided on the detector 72. A second conduit 74 is connected between the lower side wall of the box 1 and the sampling chamber 73. A solenoid valve 75 is connected in series on the second conduit 74. The water inlet end of the second conduit 74 extends to the lower part of the box 1. When the solenoid valve 75 is opened, the sewage after the bubbles are eliminated is introduced into the sampling chamber 73 through the second conduit 74 for detection.

[0043] The above solution also includes the requirement to install an automatic import function to guide wastewater into tank 1 for pretreatment, and to promptly discharge qualified wastewater after testing. Figure 1 As shown: A water inlet assembly 6 is provided on the top of the tank 1. The water inlet assembly 6 includes a first conduit 61 connected to one side of the top of the tank 1. The water inlet end of the first conduit 61 is connected to a first water pump 62. The water outlet end of the first conduit 61 extends into the tank 1 and is set towards the inner wall of the tank 1. A drainage assembly 8 is provided on one side of the tank 1 near the bottom. The drainage assembly 8 includes a drain pipe 81 connected to the bottom of the tank 1. A second water pump 82 is connected in series on the drain pipe 81. A manual valve 83 is also provided on the drain pipe 81. When the first water pump 62 is turned on, the sewage is introduced into the tank 1 through the first conduit 61 for pretreatment. Finally, the second water pump 82 is turned on to discharge the qualified sewage through the drain pipe 81.

[0044] The above solutions also require supporting the sliding plate 31 and limiting its movement trajectory, such as... Figure 4 As shown: Limiting components 5 are symmetrically arranged on both sides of the inner wall of the housing 1 near the sliding plate 31. The limiting components 5 include a limiting groove 51 opened in the inner wall of the housing 1 along the horizontal direction. A limiting block 52 is slidably connected in the limiting groove 51. The end of the limiting block 52 away from the limiting groove 51 is fixedly connected to the sliding plate 31. During the movement of the sliding plate 31, the limiting block 52 will be driven to slide on the limiting groove 51, thereby limiting the movement trajectory of the sliding plate 31 and the bottom rivet 32.

[0045] Example 3

[0046] like Figures 1-5As shown: First, the first water pump 62 is turned on to introduce sewage into the tank 1 through the first conduit 61 for pretreatment. After entering the tank 1, the sewage will pass through the filter screen 9 to remove impurities and particulate matter. Then it will fall to the bottom of the tank 1. When a large number of bubbles are attached to the surface of the sewage, the limit ball 44 is pulled to drive the connecting rope 43 to slide on the connecting hole 45, thereby driving the sliding plate 31 and the rivet 32 ​​at the bottom to puncture the bubbles. During the movement, the sliding plate 31 will squeeze the spring 42. When the limit ball 44 is released, the sliding plate 31 will automatically spring back to its original position by the elastic force of the spring 42. The knocking head 41 on the sliding plate 31 will collide with the inner wall of the tank 1 to generate vibration and further eliminate the bubbles. Then, the solenoid valve 75 is turned on to introduce the sewage after the bubbles are eliminated into the sampling chamber 73 through the second conduit 74 for testing. When the test is qualified, the second water pump 82 is turned on to discharge the qualified sewage through the drain pipe 81.
