Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater sampling technology, and more specifically to a wastewater sampling device for wastewater treatment. Background Technology
[0002] In today's context of close integration between industrial production and environmental protection, wastewater treatment has become an indispensable and crucial link in the wastewater treatment sector for various industrial enterprises and municipalities. The effectiveness of wastewater treatment directly affects the recycling of water resources, the protection of the ecological environment, and the social responsibility and compliance of enterprises. Accurate and reliable wastewater sampling is the prerequisite and foundation for controlling wastewater treatment quality and optimizing treatment processes.
[0003] As shown in the prior art published in CN217845716U, although the prior art, through the setting of the cover plate, allows the sampling device to be pressed down by simply holding the handle during sampling, allowing wastewater to flow from the inlet into the sample storage cylinder, making wastewater sampling easier and avoiding the phenomenon of wastewater splashing onto the hands of the staff during sampling, and also improving wastewater sampling efficiency, the cover plate in this technical solution opens at the same time as the sample storage cylinder falls into the wastewater. This means that the sample storage cylinder cannot collect wastewater at a specific depth, thus reducing the practicality of the technical solution. Utility Model Content
[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a wastewater sampling device for wastewater treatment. A spring pushes a limiting plate and an adjusting column downwards, causing a sealing plug on the adjusting column to block the liquid hole. This facilitates placing the sampling cylinder inside wastewater at different depths. Then, the adjusting column is lifted, causing the sealing plug to separate from the liquid hole, allowing wastewater to flow through the liquid hole into the sampling cylinder, thus completing the wastewater sampling operation. This improves the practicality of this utility model and solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater sampling device for wastewater treatment, comprising a sampling cylinder for sampling wastewater, wherein the sampling cylinder samples wastewater at different depths by means of an adjustment component;
[0006] The adjustment assembly includes an adjustment column disposed inside the sampling cylinder, a sealing plug is installed at the bottom end of the adjustment column, and a liquid hole is opened on one side of the bottom end of the sampling cylinder corresponding to the sealing plug, and the bottom end of the sealing plug extends into the liquid hole;
[0007] The top of the adjusting column passes through the sampling cylinder and is fitted with a handle. A limiting plate is fitted on the outside of the top of the adjusting column, and telescopic rods for connecting to the top of the inner cavity of the sampling cylinder are installed on both ends of the limiting plate. A spring is fitted on the outside of the bottom end of the telescopic rod.
[0008] In a preferred embodiment, an air hole is provided on one side of the top of the sampling tube corresponding to the adjusting column. The adjusting column is located inside the air hole, and the diameter of the air hole is larger than the diameter of the adjusting column. By setting the air hole to be larger than the adjusting column, the air inside the sampling tube can flow stably when the handle is separated from the air hole and the sealing plug is separated from the liquid hole, thereby facilitating the flow of wastewater into the sampling tube through the liquid hole.
[0009] In a preferred embodiment, the cross-section of the liquid hole and the bottom cross-section of the sealing plug are both funnel-shaped, and the outer side of the bottom of the sealing plug is in contact with the inner wall of the liquid hole. By making the cross-section of the liquid hole and the cross-section of the sealing plug both funnel-shaped, the sealing plug can fit tightly against the liquid hole, thereby ensuring the sealing effect of the sealing plug on the liquid hole. At the same time, the liquid hole can also limit the sealing plug, preventing the sealing plug from falling off the sampling cylinder and ensuring the stability of the sealing plug in use.
[0010] In a preferred embodiment, a float ring is fitted over the top of the sealing plug, and measuring plates are installed at the top of both ends of the float ring. The top of the measuring plate passes through the sampling tube and extends to the outside of the top of the sampling tube. A liquid level line is machined on the side of the measuring plate near the handle. Through the suspending effect of the float ring, the wastewater can lift the float ring and move it upward. At the same time, the float ring drives the measuring plate to move upward to the outside of the sampling tube, so that the staff can understand the amount of wastewater sampled by looking at the liquid level line on the measuring plate and improve the sampling accuracy.
[0011] In a preferred embodiment, a handle is installed at the top of the sampling cylinder, and the handle is located outside the top of the grip. An anti-slip ring is fitted on the outside of the top of the handle. The handle makes it easier for the staff to hold the sampling cylinder, and the anti-slip ring can effectively enhance the stability of the staff holding the handle.
[0012] In a preferred embodiment, the inner diameter of the floating ring is greater than the length of the limiting plate. By setting the inner diameter of the floating ring to be greater than the length of the limiting plate, the limiting plate will not obstruct the vertical movement of the floating ring, thereby ensuring the smoothness of the floating ring's movement.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. The spring pushes the limiting plate and adjusting column downward, and the sealing plug on the adjusting column seals the liquid hole, so as to facilitate the placement of the sampling tube into the wastewater at different depths. Then, the adjusting column is lifted to separate the sealing plug from the liquid hole, so that the wastewater can flow into the sampling tube through the liquid hole, thereby completing the wastewater sampling operation. The operation is simple and convenient, which can effectively improve the convenience of operation and also improve the practicality of this utility model.
[0015] 2. By setting up the float ring, when the wastewater flows into the sampling cylinder, the wastewater will push the float ring upward, and the float ring will then drive the measuring plate upward. This makes it easier for the staff to know the amount of wastewater sampled by looking at the liquid level line on the measuring plate, thus improving the accuracy of the wastewater sampling.

[0022] 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.
[0023] Refer to the instruction manual appendix Figure 1-5 This utility model provides a wastewater sampling device for wastewater treatment, including a sampling cylinder 1 for sampling wastewater, wherein the sampling cylinder 1 can sample wastewater at different depths by adjusting the component;
[0024] The adjustment assembly includes an adjustment column 2 disposed inside the sampling cylinder 1. A sealing plug 3 is installed at the bottom end of the adjustment column 2, and a liquid hole 4 is opened on one side of the bottom end of the sampling cylinder 1 corresponding to the sealing plug 3. The bottom end of the sealing plug 3 extends into the liquid hole 4. The top end of the adjustment column 2 passes through the sampling cylinder 1 and is equipped with a handle 5. A limiting plate 6 is sleeved on the outside of the top end of the adjustment column 2, and telescopic rods 7 for connecting to the top of the inner cavity of the sampling cylinder 1 are installed on both ends of the limiting plate 6. A spring 8 is sleeved on the outside of the bottom end of the telescopic rod 7.
[0025] When the staff operates the sampling tube 1 to sample wastewater, the sampling tube 1 is equipped with a handle 13 at the top, and the handle 13 is located outside the top of the grip 5. The handle 13 is fitted with an anti-slip ring 14, which allows the staff to hold the sampling tube 1 by gripping the handle 13. This makes it easier to hold the sampling tube 1 in a suitable position. In addition, the anti-slip ring 14 can enhance the friction between the staff's hand and the handle 13, thereby ensuring the tightness between the staff's hand and the handle 13 and preventing the handle 13 from coming loose.
[0026] After holding the sampling cylinder 1 to the appropriate position, the staff then presses the sampling cylinder 1 down into the wastewater. Because the sealing plug 3 used to seal the liquid hole 4 is limited by the spring 8, the downward pressure will not open the sealing plug 3, thus making it easier for the staff to press the sampling cylinder 1 down to the appropriate depth. Then, the hand holding the handle 13 pulls the handle 5, which drives the limiting plate 6 and the sealing plug 3 on the adjusting column 2 to move upward. The upward movement of the limiting plate 6 compresses the spring 8, and the sealing plug 3 moves upward and separates from the liquid hole 4.
[0027] Meanwhile, since an air hole 9 is provided on one side of the top of the sampling cylinder 1 corresponding to the adjusting column 2, and the adjusting column 2 is located inside the air hole 9, and the diameter of the air hole 9 is larger than the diameter of the adjusting column 2, the air inside the sampling cylinder 1 is unobstructed, and the water flow and air exhaust are synchronized to form a stable flow, so that the wastewater can flow smoothly into the sampling cylinder 1, thereby facilitating the sampling operation of the wastewater.
[0028] During sampling, to facilitate timely understanding of the wastewater sampling volume, a float ring 10 is fitted onto the outer side of the top of the sealing plug 3. Measuring plates 11 are installed at both ends of the float ring 10. The top of the measuring plate 11 penetrates the sampling cylinder 1 and extends to the outside of the top of the sampling cylinder 1. A liquid level line 12 is machined on the side of the measuring plate 11 near the handle 5. Thus, when wastewater flows into the sampling cylinder 1, the wastewater will push the float ring 10 upwards, which in turn drives the measuring plate 11 upwards. This allows staff to easily understand the wastewater sampling volume via the liquid level line 12 on the measuring plate 11, improving the accuracy of wastewater sampling. Furthermore, to ensure smooth upward movement of the float ring 10, the inner diameter of the float ring 10 is larger than the length of the limiting plate 6, so that the limiting plate 6 does not obstruct the upward movement of the float ring 10, thereby ensuring the stability and smoothness of the float ring 10 driving the measuring plate 11 upwards.
[0029] When the appropriate amount of wastewater is obtained, the staff releases the handle 5, thereby freeing the adjusting column 2 from its position. At the same time, the spring 8 on the telescopic rod 7 pushes the limiting plate 6 to reset. The limiting plate 6 then moves the adjusting column 2 and the sealing plug 3 downward, causing the sealing plug 3 to be embedded inside the liquid hole 4 for sealing. This seals the wastewater inside the sampling cylinder 1, thus realizing the wastewater sampling operation.
[0030] Furthermore, since the cross-section of the liquid hole 4 and the bottom cross-section of the sealing plug 3 are both funnel-shaped, and the outer bottom of the sealing plug 3 is in contact with the inner wall of the liquid hole 4, the sealing plug 3 can be completely fitted inside the liquid hole 4, thereby ensuring the sealing effect of the sealing plug 3 on the liquid hole 4. In addition, the liquid hole 4 can also limit the sealing plug 3 to prevent the sealing plug 3 from falling out of the sampling cylinder 1.
[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
