Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a sampling device for industrial wastewater that is piped into a sewer system. Background Technology

[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, and finished products lost with the wastewater, as well as pollutants generated during production. With the volume of industrial wastewater decreasing year by year and the cost of industrial wastewater treatment increasing, wastewater treatment plants need to reduce costs. Therefore, it is necessary to sample and analyze industrial wastewater to select appropriate treatment processes and agents, thereby determining a more accurate wastewater treatment cost.

[0003] In existing technologies, when manually sampling industrial wastewater, the sampling bucket on the sewage pipe will retain a portion of the wastewater during the discharge process. Sampling personnel will directly open the sampling bucket and take a sample from inside. However, ordinary sampling buckets can only retain wastewater samples at one point in time. If the sample in the sampling bucket is not removed, the sampling bucket cannot take samples again when the composition of the industrial wastewater changes. This fails to achieve the function of real-time sampling, resulting in the composition of the sample wastewater being different from that of the actual wastewater, making it impossible for wastewater treatment plants to charge wastewater treatment fees reasonably.

[0004] In response, Chinese patent application number 202122001482.0 discloses a sampling device for the quality and quantity of industrial wastewater in a pipeline system. This patent allows industrial wastewater to first enter the sampling inner tank through an inlet pipe. When the sampling inner tank is full, the wastewater overflows into the sampling outer tank and is discharged through the outlet pipe. The wastewater in the sampling inner tank is always in a flowing state. When new wastewater is discharged, the old wastewater in the sampling inner tank is replaced by the new wastewater. The quality of the wastewater in the sampling inner tank is the same as that of the wastewater discharged at this time. Excess wastewater overflows into the sampling outer tank and is discharged. The wastewater in the sampling inner tank serves as a sample, and the sampling inner tank can achieve the function of real-time sample retention, avoiding the situation where the sample wastewater does not match the actual wastewater.

[0005] However, when using the sampling device provided by the aforementioned patent, the sewage overflows from the inner sampling bucket to the outer sampling bucket and is then discharged through the outlet pipe. During this period, impurities in the sewage will settle at the bottom of the inner sampling bucket. Even if the inner sampling bucket is stirred with a bladed stirring shaft, impurities will still remain in the inner sampling bucket, and the amount will increase over time, resulting in inaccurate sampling results. Utility Model Content

[0012] The inlet is close to the upper surface of the diversion plate; the opening is located below the through-hole; the diversion outlet is offset from the opening.

[0013] A one-way valve is installed at the water inlet.

[0014] The sampling device for industrial wastewater supplied by this utility model preferably includes a cylinder as the horizontal moving mechanism; the horizontal moving mechanism is fixed to the sampling bucket; the telescopic shaft of the horizontal moving mechanism is fixed to the right end of the diversion plate; and the telescopic shaft of the horizontal moving mechanism faces to the left.

[0015] The sampling device for industrial wastewater in the pipeline provided by this utility model preferably includes a flow channel, a water storage tank and a sewage outlet in the diversion channel.

[0016] The flow channel is connected to the diversion inlet; the flow channel is connected to the water storage tank; the water storage tank is connected to the diversion outlet; the sewage outlet is located below the water storage tank; the sewage outlet is connected to the water storage tank; the opening is located below the sewage outlet.

[0017] The sampling device for industrial wastewater supplied by this utility model preferably includes a first electromagnetic check valve between the water storage tank and the diversion outlet; a second electromagnetic check valve between the sewage outlet and the water storage tank; and the water control check valve is an electromagnetic check valve.

[0018] The side wall of the water storage tank is also provided with a first water level sensor and a second water level sensor; the first water level sensor is located above the second water level sensor; the first water level sensor is electrically connected to the water control check valve; the first water level sensor is electrically connected to the first electromagnetic check valve; the first water level sensor is electrically connected to the second electromagnetic check valve; the second water level sensor is electrically connected to the first electromagnetic check valve; the second water level sensor is electrically connected to the second electromagnetic check valve.

[0019] The sampling device for industrial wastewater supplied by this utility model preferably has the through-hole and the diversion inlet in a frustum shape; the cross-sectional area of ​​the through-hole and the diversion inlet gradually decreases from top to bottom; the cross-sectional area of ​​the outlet is smaller than the cross-sectional area of ​​the through-hole; and the cross-sectional area of ​​the outlet is smaller than the cross-sectional area of ​​the diversion inlet.

[0020] The above technical solution has the following advantages or beneficial effects:

[0021] This utility model provides a sampling device for industrial wastewater in a pipeline system, including a diversion plate. To enable real-time sampling of wastewater during discharge, the diversion plate has a through-hole, with an opening below it. Wastewater enters the opening from the inlet through the through-hole, thus achieving continuous discharge and obtaining wastewater samples from different time periods. Furthermore, for real-time sampling, a diversion inlet is located to the left of the through-hole, and a diversion outlet is located to the left of the diversion inlet. The diversion inlet and outlet are connected by a diversion channel. The diversion inlet is located at the top of the diversion plate, and the diversion outlet is located at the bottom. Wastewater enters the diversion inlet from the inlet, passes through the diversion channel, and enters the diversion outlet. The diversion outlet is offset from the opening, allowing sampling personnel to... The container samples wastewater from the diversion outlet outside the sampling bucket, improving the efficiency of wastewater sampling and reducing the probability of sampling personnel coming into contact with wastewater. Furthermore, the wastewater flows from top to bottom, preventing sedimentation of impurities and improving the accuracy of sampling results. Further, since the inlet cannot be moved, to achieve both wastewater discharge and real-time sampling, the through-hole and diversion inlet need to be connected to the inlet alternately. A horizontal moving mechanism drives the diversion plate to move left and right, adjusting the positions of the inlet, through-hole, and diversion inlet to allow wastewater to enter either the through-hole or the diversion inlet. To facilitate switching between the through-hole and diversion inlet and control wastewater flow, a one-way valve is installed at the outlet.

[0022] Existing technologies involve wastewater overflowing from the inner sampling container into the outer sampling container and then being discharged through an outlet pipe. While this method allows for real-time sampling during wastewater discharge, impurities in the wastewater settle at the bottom of the inner sampling container. Even with a bladed stirring shaft, impurities remain in the inner sampling container, increasing over time and leading to inaccurate sampling results. The sampling device for industrial wastewater supplied by this invention, however, utilizes a diversion plate to achieve real-time sampling while allowing wastewater to flow downwards, preventing sedimentation of impurities and improving the accuracy of the sampling results.

[0026] Figure 3 yes Figure 2 Enlarged diagram of the circled area. Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0028] Example 1:

[0029] like Figures 1-2 As shown, Embodiment 1 of this utility model provides a sampling device for industrial wastewater that is connected to a pipeline, including a sampling bucket 1, an inlet 2, an outlet 3, a diversion plate 4, and a horizontal moving mechanism 5;

[0030] The top of the sampling bucket 1 is provided with an opening 11; the opening 11 is connected to the inner cavity of the sampling bucket 1; the water inlet 2 is located above the opening 11; the water outlet 3 is located at the bottom of the sampling bucket 1; the water outlet 3 is connected to the inner cavity of the sampling bucket 1.

[0031] The diverter plate 4 is horizontally positioned; the diverter plate 4 is located above the sampling bucket 1; the horizontal moving mechanism 5 drives the diverter plate 4 to move in the left and right directions.

[0032] The flow divider 4 includes, from top to bottom, a through-hole 41, a flow divider inlet 42, a flow divider channel 43, and a flow divider outlet 44; the through-hole 41 is located to the right of the flow divider inlet 42; the flow divider outlet 44 is located to the left of the flow divider inlet 42; the flow divider inlet 42 is located at the top of the flow divider 4; the flow divider outlet 44 is located at the bottom of the flow divider 4; the flow divider inlet 42 and the flow divider outlet 44 are connected by the flow divider channel 43; the flow divider channel 43 is located inside the flow divider 4.

[0033] The inlet 3 is close to the upper surface of the diversion plate 4; the opening 11 is below the through port 41; the diversion outlet 42 is offset from the opening 11.

[0034] A one-way valve 31 is installed at the three water inlets.

[0035] When using the industrial wastewater sampling device provided in Embodiment 1 of this utility model, wastewater is discharged from the inlet 2, and the discharge is controlled by the one-way valve 31. When it is necessary to discharge wastewater into the sampling tank 1, the horizontal moving mechanism 5 drives the diversion plate 4 to move to the left, so that the inlet 2 is aligned with the through-hole 41, the one-way valve 31 is opened, and the wastewater enters the through-hole 41 from the inlet 2, and then enters the opening 11 from the through-hole 41, thus entering the sampling tank 1. The wastewater is discharged from the outlet 3 and sent to the next wastewater treatment pond. When sampling wastewater, if the inlet 2 is aligned with the through-hole 41, the one-way valve 31 is closed. The horizontal moving mechanism 5 drives the diversion plate 4 to move to the right, so that the inlet 2 is aligned with the diversion inlet 42. The one-way valve 31 is then opened, and the wastewater enters the diversion inlet 42 from the inlet 2. The wastewater then passes through the diversion channel 43 and flows out from the diversion outlet 44. The sampling personnel use test tubes to sample the wastewater at the diversion outlet 44. After sampling is completed, the one-way valve 31 is closed, and the wastewater continues to be discharged into the sampling bucket 1.

[0036] The sampling device for industrial wastewater in pipelines provided in Embodiment 1 of this utility model includes a diversion plate 4. To enable real-time sampling of wastewater during discharge, the diversion plate 4 has a through-hole 41, with an opening 11 below it. Wastewater enters the opening 11 from the inlet 2 through the through-hole 41, thus achieving continuous discharge and obtaining wastewater samples from different time periods. Furthermore, to enable real-time sampling, a diversion inlet 42 is provided to the left of the through-hole 41, and a diversion outlet 44 is provided to the left of the diversion inlet 42. The diversion inlet 42 and the diversion outlet 44 are connected by a diversion channel 43. The diversion inlet 42 is located at the top of the diversion plate 4, and the diversion outlet 44 is located at the bottom of the diversion plate 4. Wastewater enters the diversion inlet 42 from the inlet 2, passes through the diversion channel 43, and enters the diversion outlet 44. The diversion outlet 42 is offset from the opening 11. The sampling personnel can use a container to sample sewage from the diversion outlet 44 outside the sampling bucket 1, which improves the efficiency of sewage sampling and reduces the probability of contact between the sampling personnel and sewage. Moreover, the sewage flows from top to bottom, which can avoid the sedimentation of impurities in the sewage and improve the accuracy of sampling results. Furthermore, since the inlet 2 cannot be moved, in order to realize the sewage discharge function and real-time sampling function, the through port 41 and the diversion inlet 42 need to be connected to the inlet 2 alternately. The diversion plate 4 is driven to move in the left and right directions by the horizontal moving mechanism 5, thereby adjusting the position between the inlet 2, the through port 41 and the diversion inlet 42, so that the sewage can enter the through port 41 or the diversion inlet 42 respectively. In order to facilitate the switching between the through port 41 and the diversion inlet 42 and control the sewage flow, a one-way valve 31 is set at the outlet 2.

[0037] Existing technology involves wastewater overflowing from the inner sampling container into the outer sampling container and then being discharged through an outlet pipe. This method can achieve real-time sampling while discharging wastewater. However, impurities in the wastewater will settle at the bottom of the inner sampling container during this process. Even if the inner sampling container is stirred with a bladed stirring shaft, impurities will still remain in the inner sampling container, and the amount will increase over time, leading to inaccurate sampling results. If the sampling device for industrial wastewater in the pipeline provided in Embodiment 1 of this utility model is used, the diversion plate 4 can achieve real-time sampling while the wastewater flows from top to bottom, which can avoid the sedimentation of impurities in the wastewater, thereby improving the accuracy of the sampling results.

[0038] like Figure 1 As shown in Embodiment 1 of this utility model, the sampling device for industrial wastewater is preferably configured such that, in order to realize the function of the horizontal moving mechanism 5 driving the diversion plate 4 to move in the left and right directions, the horizontal moving mechanism 5 is specifically a cylinder. In order to enable the cylinder to stably push the diversion plate 4, the horizontal moving mechanism 5 is fixed on the sampling bucket 1, and the telescopic shaft of the horizontal moving mechanism 5 is fixed to the right end of the diversion plate 4. The telescopic shaft of the horizontal moving mechanism 5 faces to the left. When the diversion plate 4 needs to move to the left, the telescopic shaft of the horizontal moving mechanism 5 extends to the left, and the telescopic shaft of the horizontal moving mechanism 5 drives the diversion plate 4 to move to the left. If the diversion plate 4 needs to move to the right, the telescopic shaft of the horizontal moving mechanism 5 retracts to the right, and the telescopic shaft of the horizontal moving mechanism 5 drives the diversion plate 4 to move to the right.

[0039] like Figure 2 As shown, the sampling device for industrial wastewater in the pipeline provided in Embodiment 1 of this utility model is preferably designed so that if the wastewater flow rate is high and the sampling personnel do not use a container to sample the wastewater in time, the wastewater is likely to overflow from the diversion outlet 44. Therefore, the diversion channel 43 includes a flow channel 431, a water storage tank 432 and a sewage outlet 433.

[0040] The flow channel 431 is connected to the diversion inlet 42 and the water storage tank 432. The water storage tank 432 is connected to the diversion outlet 44. Sewage enters the flow channel 431 from the diversion inlet 42 and enters the water storage tank 432 from the flow channel 431. The water storage tank 432 can buffer the sewage to prevent it from directly hitting the diversion outlet 44, improve the tolerance of the sampling personnel in taking sewage samples, prevent sewage from overflowing from the diversion outlet 44, and reduce the probability of the sampling personnel coming into contact with sewage.

[0041] Furthermore, if the sewage in the water storage tank 432 cannot be completely drained, the remaining sewage will mix with the sewage entering the water storage tank 432 next time, thus making the real-time sampling results inaccurate. To address this, the sewage outlet 433 is located below the water storage tank 432, allowing the sewage outlet 433 to communicate with the water storage tank 432. Below the sewage outlet 433 is an opening 11. When the sampling personnel collect sewage samples, the sewage outlet 433 is closed to the water storage tank 432. After the sampling personnel finish collecting the samples, the sewage outlet 433 is connected to the water storage tank 432 to drain the remaining sewage in the water storage tank 432.

[0042] like Figures 2-3 As shown, the sampling device for industrial wastewater in the pipeline provided in Embodiment 1 of this utility model preferably has the following features: Since the wastewater discharge rate cannot be controlled, if the outlet 2 continuously discharges wastewater into the diversion inlet 42, the sampling amount of wastewater cannot be controlled when the sampling personnel use a container to collect wastewater samples. Therefore, a first electromagnetic check valve 434 is provided between the water storage tank 432 and the diversion outlet 44, and a second electromagnetic check valve 435 is provided between the sewage outlet 433 and the water storage tank 432. The water control check valve 31 is an electromagnetic check valve.

[0043] The side wall of the water storage tank 432 is also equipped with a first water level sensor 436 and a second water level sensor 437. The first water level sensor 436 is located above the second water level sensor 437, and the amount of sewage between the first water level sensor 436 and the second water level sensor 437 is used as the sampling amount.

[0044] The first water level sensor 436 is electrically connected to the water control check valve 31, the first solenoid check valve 434, and the second solenoid check valve 435; the second water level sensor 437 is electrically connected to both the first and second solenoid check valves 434 and 435. When sewage is discharged into the water storage tank 432, the first and second solenoid check valves 434 and 437 close. If the sewage reaches the level of the first water level sensor 436, the water control check valve 31 closes to prevent further discharge. Wastewater is discharged into the diversion inlet 42. Since wastewater is still being discharged into the diversion inlet 42 when the water control check valve 31 is closed, the actual amount of wastewater in the storage tank 432 is greater than the amount of wastewater at the first water level sensor 436. The second electromagnetic check valve 435 is opened to control the wastewater level to be maintained at the position of the first water level sensor 436. The second electromagnetic check valve 435 is closed and the first electromagnetic check valve 435 is opened. Wastewater enters the diversion outlet 44 from the first electromagnetic check valve 435. When the wastewater level drops to the position of the second water level sensor 436, the first electromagnetic check valve 435 is closed, thereby achieving quantitative collection of wastewater.

[0045] Furthermore, in order to prevent the remaining sewage from mixing with the sewage entering the storage tank 432 next time, thus making the real-time sampling results inaccurate, the remaining sewage is discharged by opening the second electromagnetic check valve 435.

[0046] like Figures 1-2 As shown, the sampling device for industrial wastewater in the pipeline provided in Embodiment 1 of this utility model is preferably designed so that, in order to prevent wastewater in the inlet 2 from splashing out of the through-port 41 or the diversion inlet 42, the through-port 41 and the diversion inlet 42 are frustum-shaped, and the cross-sectional area of ​​the through-port 41 and the diversion inlet 42 gradually decreases from top to bottom. The cross-sectional area of ​​the outlet 2 is smaller than the top cross-sectional area of ​​the through-port 41 and the cross-sectional area of ​​the outlet 2 is smaller than the top cross-sectional area of ​​the diversion inlet 42.

[0047] In summary, the sampling device for industrial wastewater provided by this utility model can solve the problem that impurities in wastewater will settle at the bottom of the sampling tank during use, and increase over time, leading to inaccurate sampling results. This device improves the accuracy of sampling results and increases the efficiency of wastewater sampling.
