Description

Technical Field

[0001] This utility model relates to the field of sampling pump technology, specifically to a sampling pump slag interception and water shortage power-off device. Background Technology

[0002] A sampling pump is a specialized device used to quantitatively extract representative samples from fluid media (gas, liquid, or solid-liquid mixtures). Its core function is to ensure that the collected samples accurately reflect the composition, concentration, or physical properties of the overall medium, providing a reliable basis for subsequent analysis.

[0003] However, due to the poor water environment of the wastewater sampling, the water flow generated when the sampling pump is pumping water can easily cause nearby floating objects, suspended matter and debris to be adsorbed on the water intake, causing the water intake to be blocked, which is not conducive to the water intake of the sampling pump. The sampling pump needs to be cleaned repeatedly. Existing devices often install a filter device on the outside of the sampling pump. However, the filter device will also become blocked after a period of use, which is not conducive to the operation of the sampling pump. Utility Model Content

[0011] As one of the preferred technical solutions, the aperture of the second slag-blocking wire mesh is larger than that of the first slag-blocking wire mesh.

[0012] As one of the preferred technical solutions, the protective cylinder has a first slag-blocking hole on its side wall and a second slag-blocking hole at its bottom, forming a slag-blocking structure.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0034] In existing technologies, due to the poor water environment during wastewater sampling, the water flow generated by sampling pump 2 easily causes nearby floating objects, suspended solids, and debris to adhere to the water intake, leading to blockage. This hinders the water intake operation of sampling pump 2, requiring repeated cleaning and potentially causing it to malfunction. Existing devices often include an external filter for sampling pump 2; however, this filter also becomes clogged after a period of use, negatively impacting pump operation.

[0035] Example 1

[0036] This embodiment 1 provides a sampling pump slag interception and water shortage power-off device, such as... Figures 1-3 As shown, it includes:

[0037] The protective cylinder 1 has an internal space for placement, and the side walls and bottom of the protective cylinder 1 form a slag-blocking structure.

[0038] Sampling pump 2 is placed within the storage space;

[0039] The control component 3 is located on the side wall of the protective cylinder 1 and above the sampling pump 2, and is used to control the sampling pump 2 to open or close.

[0040] In this embodiment, the protective cylinder 1 can be a cylindrical cylinder, a square cylinder, or a polygonal cylinder; the placement space inside the protective cylinder 1 is used to place the sampling pump 2. The side walls and bottom of the protective cylinder 1 form a sludge-blocking structure, which filters the sewage, allowing only the sewage to pass through and intercepting impurities in the sewage. Finally, the sampling port of the sampling pump 2 draws the filtered sewage inside the protective cylinder 1, preventing the sampling port of the sampling pump 2 from becoming blocked and affecting the operation of the sampling pump 2. Therefore, the protective cylinder 1 plays a protective role for the sampling pump 2.

[0041] However, it is inevitable that sewage impurities cannot enter the protective cylinder 1. Sewage impurities may clog the sludge interception structure, preventing sewage from entering the protective cylinder 1. As a result, the sampling pump 2 cannot collect samples. To prevent the sampling pump 2 from burning out, this embodiment provides a control component 3, which includes an isolation plate 31, a controller 32, and a liquid level probe 33. The isolation plate 31 is installed in the placement space, and a placement groove 7 is opened on the top of the isolation plate 31. The liquid level probe 33 is installed in the placement groove 7. The liquid level probe 33 is a photoelectric liquid level sensor, which uses a photoelectric sensor to detect whether the liquid surface is blocking light, and is used to detect the water level height in the protective cylinder 1. The controller 32 is set on the isolation plate 31 and is connected to the liquid level probe 33 and the sampling pump 2 respectively. The controller 32 is used to control the sampling pump 2 to open or close.

[0042] The specific working process is as follows: Isolation plate 31 is installed above the side wall of protective cylinder 1. Isolation plate 31 blocks the entry of sewage to protect the level probe 33. Sewage enters from other parts of protective cylinder 1. When there is sewage in protective cylinder 1, the level probe 33 can sense the sewage level, allowing sampling pump 2 to perform sampling normally. When protective cylinder 1 is blocked and sewage no longer enters, the liquid level in protective cylinder 1 drops, and the level probe 33 no longer senses the level. When the water level in protective cylinder 1 is detected to be lower than the impeller of sampling pump 2, the level probe 33 transmits a signal to controller 32. Upon receiving the signal, controller 32 controls sampling pump 2 to shut down, thus stopping the sampling operation and improving the safety of sampling pump 2. After cleaning the outer surface of protective cylinder 1, sampling continues. This process protects the safe operation of sampling pump 2, saving on annual replacement and maintenance costs and labor costs associated with inspecting underwater sampling pump 2.

[0043] The specific controller 32 is model S7-300; the liquid level probe 33 is model FS-IR1902D; and the sampling pump 2 is model KNF PM25567-86.

[0044] In addition, the protective cylinder 1 has two types of installation, such as Figure 2As shown, one aspect is that the slag-blocking structure includes a first slag-blocking wire mesh 8 and a second slag-blocking wire mesh 9. The first slag-blocking wire mesh 8 is bent to form the side wall of the protective cylinder 1, and the second slag-blocking wire mesh 9 is connected to the first slag-blocking wire mesh 8 to form the bottom of the protective cylinder 1. The aperture of the second slag-blocking wire mesh 9 is larger than that of the first slag-blocking wire mesh 8.

[0045] In this embodiment, the first slag-blocking wire mesh 8 and the second slag-blocking wire mesh 9 have a certain rigidity and are not easily deformed in order to support and place the sampling pump 2. Specifically, the protective cylinder 1 can be made as needed. When the protective cylinder 1 is a cylindrical cylinder, the first slag-blocking wire mesh 8 is a square mesh, and the second slag-blocking wire mesh 9 is a circular mesh; the circumference of the second slag-blocking wire mesh 9 is the same as the length of the first slag-blocking wire mesh 8. Then, the first slag-blocking wire mesh 8 is bent and connected to the second slag-blocking wire mesh 9 with steel wire to form the protective cylinder 1. Similarly, when the protective cylinder 1 needs to be a square cylinder or a polygonal cylinder, the first slag-blocking wire mesh 8 is bent into the corresponding geometric shape and connected to the second slag-blocking wire mesh 9 to be fixed. The protective cylinder 1 is simple and convenient to make. In addition, the staff can change the size of the first slag-blocking wire mesh 8 and the second slag-blocking wire mesh 9 according to the size of the sampling pump 2, making it highly practical.

[0046] Furthermore, the aperture of the second slag-blocking wire mesh 9 is larger than that of the first slag-blocking wire mesh 8. Firstly, the apertures of both the first and second slag-blocking wire meshes 8 and 9 meet the requirements for slag interception and filtration. The smaller aperture of the first slag-blocking wire mesh 8 intercepts tiny particles, reducing their entry into the larger aperture area at the bottom for clogging and extending the clogging time at the bottom of the protective cylinder 1. This allows wastewater to enter the protective cylinder 1 more easily from the bottom. Secondly, the larger aperture of the second slag-blocking wire mesh 9 can quickly guide the fluid at the bottom, reducing water flow resistance. The cooperation of the first and second slag-blocking wire meshes 8 and 9 in the protective cylinder enhances the overall anti-clogging capability of the protective cylinder 1.

[0047] like Figure 3 and Figure 4 As shown, the second aspect is that a first slag-blocking hole 10 is provided on the side wall of the protective cylinder 1, and a second slag-blocking hole 11 is provided at the bottom of the protective cylinder 1. The first slag-blocking hole 10 and the second slag-blocking hole 11 form a slag-blocking structure. The diameter of the second slag-blocking hole 11 is larger than that of the first slag-blocking hole 10.

[0048] In this embodiment, the interception structure can be formed directly by opening holes in the protective cylinder 1, which can also achieve the purpose of interception and filtration. At this time, the protective cylinder 1 is a hollow cylinder, and the bottom and side wall of the protective cylinder 1 are integrally connected. Similarly, the protective cylinder 1 with different hole diameters is set, and the hole diameter of the second slag-blocking hole 11 is larger than that of the first slag-blocking hole 10. Sewage impurities accumulate on the first slag-blocking hole 10, reducing the blockage of the second slag-blocking hole 11, which can enhance the overall anti-clogging ability of the protective cylinder 1.

[0049] Furthermore, a pump base 4 is provided within the placement space to support the sampling pump 2. Specifically, the pump base 4 is installed in conjunction with the sampling pump 2, allowing the sampling pump 2 to be stably installed within the placement space to complete the water sampling operation. Additionally, the sampling pump 2 operates under the operation of a motor, which vibrates during operation. Therefore, the sampling pump 2 transmits the vibration force to the pump base 4, and then to the protective cylinder 1. Under the vibration, the protective cylinder 1 shakes off a certain amount of solid impurities, thereby reducing clogging of the protective cylinder 1 and extending the clogging time of the protective cylinder 1.

[0050] Furthermore, such as Figure 1 As shown, a flip-top plate 5 is hinged to one side of the top of the protective cylinder 1. The flip-top plate 5 is a filter screen. Specifically, the top of the protective cylinder 1 is the inlet of the sampling pump 2. By flipping the flip-top plate 5, it is easy to place the sampling pump 2 into the protective cylinder 1. In addition, the flip-top plate 5 closes the top of the protective cylinder 1 and is equipped with a filter screen to prevent sewage impurities from entering the interior of the protective cylinder 1. To prevent sewage impurities from flowing into the protective cylinder 1 through the gap between the flip-top plate 5 and the top of the protective cylinder 1, a sealing strip 6 is provided between the flip-top plate 5 and the protective cylinder 1. The sealing strip 6 ensures the tightness of the connection between the flip-top plate 5 and the protective cylinder 1. In addition, the connection between the flip-top plate 5 and the protective cylinder 1 can be achieved by snap-fitting or by fixing with twisted iron wire to ensure the stability of the connection between the flip-top plate 5 and the protective cylinder 1.

[0051] Furthermore, to improve the service life of the protective cylinder 1 and reduce the replacement frequency, the materials of the first slag-blocking wire mesh 8 and the second slag-blocking wire mesh 9 are set to be corrosion-resistant materials.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
