Description

Technical Field

[0001] The invention relates to the technical field of sewage sampling, in particular to an integrated sewage sampling device and sewage treatment equipment. Background Art

[0002] Water pollution sampling, also known as water pollution sampling, refers to the process of extracting water samples from polluted water according to prescribed methods and a certain proportion. By testing and analyzing the extracted water samples, the degree of water pollution, the types and contents of pollutants and other related water quality parameters can be determined.

[0003] The radial flow sedimentation tank is a traditional water treatment structure that uses the gravity sedimentation of particles or flocs to remove suspended matter in the water. Its main function is to remove the sludge settled in the sedimentation tank and the floating objects on the surface of the water. The plane of the tank is mostly circular, but there are also square ones. Wastewater enters the tank from the water inlet pipe in the center of the tank and flows slowly around the tank along the radius. The center takes in water and discharges sludge, and the periphery discharges water. The stirring force on the water body is small, which is conducive to the removal of sludge. It is widely used in water supply and sewage treatment processes, and sometimes used as a separate water treatment structure with good raw water quality.

[0004] The diameter (or side length) of the radial flow sedimentation tank is 6 to 60m, and can reach a maximum of 100m. The water depth around the tank is 1.5 to 3.0m, and the slope of the tank bottom is gentle, but it should not be less than 0.05 degrees. During the sewage treatment process using the radial flow sedimentation tank, it is necessary to extract sewage samples from the tank to monitor the sewage treatment effect and sewage water quality in real time. In order to improve the universality of the scope covered by sewage samples, it is advisable to perform sampling operations at multiple points or multiple layers for large-scale radial flow sedimentation tanks. The sewage sampling equipment commonly used at present is often independent of the sedimentation tank, and the sewage in the sedimentation tank has poor light transmittance. During the sewage sampling process, it is difficult for the sampling equipment to accurately reach the sampling position and depth in the tank and perform quantitative sampling operations. This process is time-consuming and labor-intensive, which reduces the timeliness and convenience between multi-point sewage sampling, increases the measurement and judgment errors of the overall water quality of sewage in the sedimentation tank, and reduces the overall efficiency of sewage treatment.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] To achieve quantitative sampling of sewage, Figure 4 , Fig.11 and Fig.12 As shown, a preferred embodiment of the present invention proposes an integrated sewage sampling device, including a sampling tube 1, a gas plug 11 is movably installed on the top of the sampling tube 1, a flow valve 12 is arranged at the bottom of the sampling tube 1, a cavity for accommodating sewage is arranged in the middle of the sampling tube 1, and the middle cavity of the sampling tube 1 is vacuumed before sewage is extracted. In addition, the sampling tube 1 is installed as a whole in the sampling barrel 2, and the upper inner wall of the sampling barrel 2 is circumferentially provided with a plurality of ribs that engage with the outer wall of the sampling tube 1. In addition, it also includes a solid waste bin 3 and a depth pipe 4.

[0036] The present invention can simultaneously set 1 to 8 sampling tubes 1. For the sewage sampling operation performed in a single radial flow sedimentation tank 6, the operation can be performed at different depths around and at the positions around the radial flow sedimentation tank 6. Before installing the sampling tube 1, the internal cavity thereof is evacuated through the position of the air plug 11 to make it enter a negative pressure state. The ribs arranged in the sampling tube 2 can be made of elastic materials such as rubber, sponge, silicone or plastic. The function of the ribs is to achieve the circumferential clamping effect on the sampling tube 1, and at the same time, the ribs can adapt to the diameter size changes of multiple types of sampling tubes 1. After the sampling tube 1 reaches the predetermined sampling position, the flow valve 12 is controlled by the solenoid valve to open. At this time, the external sewage is sucked into the inner side of the sampling tube 1 under the action of negative pressure. At the same time, the flow valve 12 detects the sewage flow, and the volume of sewage entering the sampling tube 1 can be measured and monitored. When the predetermined collection volume is reached, the flow valve 12 is controlled by the solenoid valve to close, and the sampling tube 1 as a whole enters a closed state again. After the sewage sampling link is completed, the staff will take out the sampling tube 1 and conduct the next step of testing on the sewage contained inside it.

[0037] Furthermore, in order to realize the rapid installation and removal of the sampling tube 1 and improve the sampling efficiency, as Figure 4 , Figure 6 , Figure 8 , Fig.11 and Fig.12 As shown, the solid waste bin 3 is arranged at the bottom of the sampling tube 2, and a partition plate 21 is fixedly installed in the middle of the inner side of the sampling tube 2. The upper space of the partition plate 21 is used to place the sampling tube 1, and the side wall of the sampling tube 2 located above the partition plate 21 is circumferentially provided with a liquid inlet groove 22. The lower space of the partition plate 21 is the solid waste bin 3, and the side wall of the solid waste bin 3 is provided with a through hole 31 for internal and external hydraulic balance. The depth pipe 4 is a "U"-shaped hollow pipe structure, and a slider 41 is slidably installed on the outside of the depth pipe 4. The side wall of the slider 41 is located at A plug-in slot 42 is provided, in which a claw 43 is slidably installed, and the end of the claw 43 is a "Y"-shaped opening structure. The outer wall of the sampling tube 2 is provided with a damping pad 23 engaged with the claw 43, and a circulating pump 44 connected to the inner cavity thereof is fixedly installed at the upper port position of the depth tube 4. The inner cavity of the depth tube 4 is filled with circulating fluid, and a magnetic column is slidably installed on the inner wall of one side of the "U"-shaped structure of the depth tube 4, and an electromagnet 45 magnetically matched with the magnetic column is fixedly installed on one side of the slider 41.

[0038] During operation, the inner side of the sampling barrel 2 is divided into two parts, an upper part and an lower part, by a partition plate 21. The upper space is used to place the sampling tube 1 for circumferential protection to prevent the sampling tube 1 from vibrating or shaking due to collision with impurities in the sewage during sewage sampling, thereby improving the accuracy of sewage feed control during sewage sampling. A liquid inlet trough 22 is provided, and sewage enters and exits from this position during sampling to directly reach the position of the flow valve 12 for easy access. When installing the sampling barrel 2, the provided claws 43 can achieve a clamping effect on the sampling barrel 2 through their own toughness deformation, and the provided damping pads 23 are used to increase the friction of the clamping part and provide a certain degree of anti-slip and anti-falling effect.

[0039] When controlling the sampling tube 1 to reach a predetermined depth position in the sewage, first control the electromagnet 45 to work, so that the electromagnet 45 and the magnetic column inside the depth pipe 4 are magnetically attracted, and then start the circulation pump 44 to work, and control the flow of the circulating liquid inside the depth pipe 4 through the circulation pump 44. At this time, the pressure difference at both ends of the magnetic column changes, and the magnetic column slides in the depth pipe 4 under the thrust, and drives the slider 41 to move synchronously through the magnetic force, thereby driving the sampling barrel 2 and the sampling tube 1 to reach the sewage sampling position of the predetermined depth. The specific depth value can be controlled and calculated by the volume of the liquid circulation in the circulation pump 44. This process avoids the negative impact caused by the poor transparency of the sewage, and can accurately and quickly deliver the sampling tube 1 to the predetermined position, accurately and efficiently.

[0040] Furthermore, the sewage impurity precipitation process by flocculation method is used to detect the physical and chemical properties of the sediment and improve the coverage of sewage samples in the sewage treatment process, such as Figures 7 to 11 As shown, the outer wall of the solid waste bin 3 is provided with a sedimentation trough 32 with an arc-shaped cross-section, and an extraction bin 5 is slidably installed in the sedimentation trough 32. The extraction bin 5 is an incomplete cylindrical structure, and the outer contour diameter of the extraction bin 5 is the same as the outer contour diameter of the sampling tube 2. A tension spring 51 is arranged between the upper part of the extraction bin 5 and the solid waste bin 3, and the bottom of the extraction bin 5 is a conical disc structure that gradually shrinks downward, and a distance sensor 52 is fixedly installed at the center of the conical disc structure.

[0041] During operation, in the initial state, the extraction bin 5 is located at the lowest position of the sedimentation tank 32 under the elastic force of the tension spring 51. At this time, the solid waste bin 3 is in a fully open state. When it is necessary to sample the bottom sludge, the sampling tube 2 is controlled by the circulation pump 44 to reach the sludge layer. At this time, the solid waste bin 3 sinks into the sludge layer, and the conical disk at the bottom of the extraction bin 5 can enhance its downward penetration in the sludge. During the initial contact with the sludge at the bottom of the extraction bin 5, until it completely passes through the sludge layer and contacts the bottom of the radial flow sedimentation tank 6, the sensing value of the distance sensor 52 changes relatively. The downward displacement of the sampling tube 2 controlled by the circulation pump 44 can measure the thickness of the sludge layer, which assists in judging the degree of sewage treatment. After the extraction bin 5 is immersed in the sludge layer, part of the sludge immediately flows into and fills the internal space of the extraction bin 5, and subsequently moves up synchronously with the extraction bin 5, thereby completing the sludge sampling work.

[0042] Furthermore, in order to ensure that a predetermined volume of sludge can be extracted in a single extraction operation, Figures 7 to 11 As shown, a converging plate 53 is symmetrically installed on the outer side of the extraction chamber 5 by a hinged manner, a torsion spring is provided at the hinged portion of the converging plate 53, and the two converging plates 53 are in a semi-cylindrical state when combined, the inner contour diameter of the converging plate 53 is larger than the outer contour diameter of the sampling tube 2, and scraping grooves 54 are evenly opened on the bottom of the converging plate 53, and docking pieces 55 are symmetrically installed on the outer wall of the sampling tube 2 and the outer wall of the extraction chamber 5, and a buckle 56 is installed between the upper and lower docking pieces 55, and a gathering rope 57 is fixedly connected to the outer wall of the converging plate 53, and the other end of the gathering rope 57 is fixedly connected to the outer wall of the sampling tube 2 after sliding through the docking piece 55.

[0043] When the extraction bin 5 is at the lowest position of the sedimentation tank 32, the pulling degree of the gathering rope 57 is the greatest. Under this effect, the two oppositely installed converging plates 53 are both in an open state of outward expansion. In the process of the sampling tube 2 moving into the sludge, the converging plates 53 are synchronously embedded in the sludge layer in a stable expansion posture. When the extraction bin 5 reaches the bottom of the radial flow sedimentation tank 6, it is no longer lowered due to the blocking effect of the bottom. At this time, relative sliding occurs between the extraction bin 5 and the solid waste bin 3, and the two gradually enter a nested state, and in this process overcome the elastic force of the tension spring 51 and cause it to gradually deform and shrink. At the same time, affected by the shortening of the distance and the torsion of the torsion spring, the shape of the gathering rope 57 changes synchronously, and the converging plate 53 in the expanded state begins to deflect and move, and in the process of deflection, pushes the sludge in front of its moving path. Into the extraction bin 5, the scraper groove 54 arranged at the bottom of the converging plate 53 can enhance the separation degree of the sludge from the bottom of the radial flow sedimentation tank 6 during the pushing process of the sludge. In order to improve the flow smoothness of the sludge entering the extraction bin 5 and the solid waste bin 3, a through hole 31 is provided to balance the hydraulic pressure inside and outside the solid waste bin 3. When the extraction bin 5 completely enters the sedimentation tank 32, the two converging plates 53 installed opposite to each other are merged. At this time, the extraction bin 5 and the converging plate 53 are combined into a cylindrical structure which is sleeved on the lower part of the solid waste bin 3 and blocks the lower part of the solid waste bin 3. The collected sludge is contained in the internal cavity formed by the solid waste bin 3 and the converging plate 53. The sludge collection operation is completed. After the extraction bin 5 reaches the predetermined position, the connection state between the extraction bin 5 and the solid waste bin 3 is fixed by the snap action between the buckle 56 and the docking piece 55.

[0044] Furthermore, in order to reduce the adhesion of sludge on both sides of the solid waste bin 3 during the sludge extraction process, Figure 8 and Fig. 9 As shown, a ball plunger is fixedly installed on the upper part of the extraction bin 5, a spherical hole 33 engaged with the head of the ball plunger is opened in the middle of the sedimentation tank 32, and the engaging force between the ball plunger and the spherical hole 33 is greater than the maximum torsion of the torsion spring at the hinge part of the converging plate 53, and a retaining rod 46 is movably installed at the end of the claw 43, and the axis of the retaining rod 46 is parallel to the axis of the sampling tube 2, a gap is reserved between the bottom of the retaining rod 46 and the outer wall of the sampling tube 2, and the converging plate 53 is located on the inner side of the retaining rod 46 after being merged.

[0045] When the extraction bin 5 approaches the solid waste bin 3 and performs the sludge filling operation, the ball plunger slides synchronously along the side wall of the sedimentation tank 32. When the ball plunger passes through the spherical hole 33, it is temporarily nested and blocked, and vibrates under the elastic force of its internal spring, thereby transmitting the vibration to the extraction bin 5. The sludge adhering to the outer layer of the extraction bin 5 is removed through intermittent continuous vibration. At the same time, the inertia is used to separate the sludge on both sides of the extraction bin 5, thereby improving the overall cleanliness of the bottom of the sampling tube 2 after the sludge extraction operation, and facilitating the subsequent sludge sample removal process by the staff.

[0046] In addition, in order to realize the convenience and accuracy of multi-point sampling operation in the radial flow sedimentation tank 6, Figures 1 to 5 As shown, the present invention also provides a sewage treatment device, including a sedimentation tank 6, the sedimentation tank 6 is cylindrical, a trestle 61 is fixedly installed on the upper part of the sedimentation tank 6, an input pipe 62 is arranged in the middle part of the sedimentation tank 6, a stirring ring 63 is rotatably installed on the input pipe 62, a water pump for pumping sewage in and a motor for driving the stirring ring 63 to rotate are fixedly installed on the trestle 61, a stirring frame 64 is arranged at the bottom of the stirring ring 63, and a foam scraping rod 65 is symmetrically arranged on both sides of the upper part of the stirring ring 63 perpendicular to the axial direction thereof, and the lower part of the foam scraping rod 65 is provided with a stirring frame 64, and a stirring frame 64 is arranged on both sides of the upper part of the stirring ring 63 perpendicular to the axial direction thereof. A foam scraper plate 66 is hingedly installed on the part, and a discharge bin matched with the foam scraper plate 66 is arranged on the upper part of the sedimentation tank 6. A shift seat 7 is slidably installed on the foam scraper rod 65, and angle plates 71 are symmetrically installed on both sides of the shift seat 7. A depth pipe 4 is movably installed on the angle plate 71, and a double-axis motor 72 for driving the angle plates 71 on both sides to rotate is fixedly installed in the middle of the shift seat 7. The length of the foam scraper rod 65 is greater than the depth value of the sedimentation tank 6, and the length of the depth pipe 4 is greater than the depth value of the sedimentation tank 6 and less than the length of the foam scraper rod 65.

[0047] By integrally installing the shift seat 7 on the scraper rod 65, when facing the sewage sampling operation inside the large-area radial flow sedimentation tank 6, a driving device, such as an electric slider or a pneumatic slider, can be added to the shift seat 7 to provide the shift seat 7 with the ability to move on the scraper rod 65. In the initial sewage purification and sedimentation process, in order to facilitate the stable sedimentation process, the angle plate 71 is driven to rotate by the operation of the dual-axis motor 72, thereby driving the depth pipe 4 to deflect and put it in a horizontal position. At this time, the sampling tube 2 is also in a horizontal state, and the sampling tube 2 is above the sewage liquid surface, which does not cause any disturbance to the early sewage treatment process. There is no interference or influence, and the sewage treatment process does not interfere with the state of the sampling cylinder 2 and the sampling tube 1 inside it. The two are combined with each other and are independent of each other. When the sewage treatment is completed and sampling and detection operations are required, the operation of the dual-axis motor 72 causes the depth tube 4 to deflect, so that it changes from a horizontal state to a vertical state. At the same time, the sampling cylinder 2 also gradually moves downward from above the sewage surface, and cooperates with the work of the circulating pump 44 to reach the sewage sampling position at a predetermined depth. The whole process does not require additional assistance and promotion from the staff. It is simple and convenient, and the sampling control is accurate and efficient, saving manpower and material resources and improving the overall efficiency of sewage treatment.
