Description

Technical Field

[0001] This utility model specifically relates to the field of wastewater sampling technology, and more specifically to a stratified sampling device used in the wastewater treatment process. Background Technology

[0002] Wastewater treatment is the process of treating wastewater generated in production and daily life through physical, chemical, and biological means to meet discharge standards or reuse requirements. In many steps of wastewater treatment, it is necessary to perform stratified sampling and treatment of wastewater at different depths. For example, the concentration of suspended solids at different depths in the sedimentation tank, the impact of flow velocity differences in pipe cross-sections on pollutant distribution, the microbial activity in different sections of the biological treatment tank, and the pollutant removal rate gradient in the deep treatment unit. By using stratified data to locate treatment bottlenecks, the entire wastewater treatment process can be precisely controlled.

[0003] However, in practice, it has been noted that most current stratified sampling methods require workers to take multiple samples. For example, in sedimentation tanks, samples are taken at 0.5 meters, 1 meter, and 1.5 meters, which requires three samplings. After each sampling, a new sampling bottle needs to be used for the next sampling. Furthermore, the sampling bottles after each sampling need to be labeled in order to prevent confusion. This makes the entire sampling process cumbersome, consumes a lot of time, and results in low sampling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a stratified sampling device for wastewater treatment. Multiple wastewater sampling cylinders can be fixedly connected according to sampling distances using connecting rods of different lengths, ensuring simultaneous sampling of wastewater at different depths, thus improving efficiency. Furthermore, each wastewater sampling cylinder has a sealed single-opening inlet / outlet seat at its bottom to ensure the airtightness of the internal sample. The bottom support frame and the cooperating opening and closing steel wire rope work together to allow multiple single-opening inlet / outlet seats to open simultaneously for sampling, further improving sampling efficiency. This invention aims to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stratified sampling device for wastewater treatment includes several connecting rods and wastewater sampling tubes arranged in a rectangular array, with the connecting rods and wastewater sampling tubes spaced apart from each other.

Detailed Implementation

[0032] 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.

[0033] Please see Figure 1-8 This utility model provides a stratified sampling device for wastewater treatment, including a plurality of connecting rods 1 and wastewater sampling cylinders 2 arranged in a rectangular array, with the connecting rods 1 and wastewater sampling cylinders 2 spaced apart from each other;

[0034] Each wastewater sampling tube 2 is fixedly connected to a single-opening inlet / outlet seat 7 at its bottom, and a bottom support frame 8 is fixedly connected below the single-opening inlet / outlet seat 7. The single-opening inlet / outlet seat 7 includes a conical connecting cover 71 that communicates with the inner side of the wastewater sampling tube 2.

[0035] A conical blocking cover 72 is fixedly connected to the conical connecting cover 71, and a blocking ball 74 is placed between the conical connecting cover 71 and the conical blocking cover 72. An extension rod is integrally provided below the blocking ball 74, and the end of the extension rod extends through the conical connecting cover 71 to the bottom of the conical connecting cover 71.

[0036] Furthermore, the conical blocking cover 72 is provided with fan-shaped holes 73 in a ring array, and a compression spring 75 is fixedly connected to the inner side of the conical blocking cover 72, and the other end of the compression spring 75 is fixedly connected to the top of the blocking ball 74.

[0037] By adopting the above technical solution, the wastewater sampling cylinder 2 and the conical connecting cover 71 can be combined arbitrarily due to their versatility, reducing the cost of use. Moreover, the compression spring 75 inside the conical blocking cover 72 pushes the blocking ball 74 to seal the bottom of the conical connecting cover 71, which can ensure the sealing of the inside of the wastewater sampling cylinder 2, thereby ensuring the accuracy of the sample. Furthermore, this bottom-in-out design can also prevent the sample from flowing out when tilted.

[0038] Furthermore, the bottom support frame 8 includes a hollow tube frame 81 sleeved on the bottom of the conical connecting cover 71, and both ends of the hollow tube frame 81 are threaded with locking bolts 83 in an annular array, and the hollow tube frame 81 is provided with water inlet holes 82 in an annular array.

[0039] More specifically, each of the aforementioned water inlet holes 82 is provided with a pin seat 84 integrally formed with the hollow pipe frame 81 on both sides, and an opening lever 9 is movably connected between the two aforementioned pin seats 84.

[0040] The hollow tube frame 81 is fixedly connected to the end of the connecting rod 1 at the bottom.

[0041] By adopting the above technical solution, the hollow tube frame 81 is fitted onto the lower part of the conical connecting cover 71, and the connection is fixed by the locking bolts 83 arranged in a rectangular array on the hollow tube frame 81. Wastewater can enter the lower part of the conical connecting cover 71 through the water inlet hole 82 on the hollow tube frame 81. The hollow tube frame 81 and the connecting rods 1 of different lengths cooperate with each other to sample wastewater samples of different depths at one time, thereby improving the efficiency of stratified sampling.

[0042] Furthermore, the opening lever 9 includes a rotating lever 91 and a reverse opening lever 93 that are movably connected to the pin seat 84, and the end of the rotating lever 91 is in transmission engagement with the end of the reverse opening lever 93, wherein a wire rope groove 92 is provided at the end of the rotating lever 91 away from the reverse opening lever 93.

[0043] More specifically, the opening and closing wire rope 3 passes through the wire rope groove 92, and a cylindrical stop block corresponding to the wire rope groove 92 is fixedly connected to the outside of the opening and closing wire rope 3, and the cylindrical stop block is engaged with the wire rope groove 92.

[0044] Furthermore, the top of the wastewater sampling cylinder 2 is integrally provided with a connecting sleeve 5, and the end of the connecting rod 1 is fixedly connected to the inner side of the connecting sleeve 5. The side of the connecting sleeve 5 is also provided with a threaded vent bolt 6 for the wastewater sampling cylinder 2.

[0045] Furthermore, one end of the vent bolt 6 extends through the wastewater sampling cylinder 2 to the inner side of the wastewater sampling cylinder 2, and the inner side of the vent bolt 6 is provided with a T-shaped air hole, and one end of the air hole is connected to the inner side of the wastewater sampling cylinder 2.

[0046] The air vent allows air to be expelled from the inside of the wastewater sampling cylinder 2 during sampling. Due to the surface tension of water and the small diameter of the vent, wastewater will not enter the inside of the wastewater sampling cylinder 2 through the vent.

[0047] More specifically, the end of the reverse opening lever 93 away from the rotating lever 91 is located below the blocking ball 74, and the end of the rotating lever 91 contacts the bottom of the extension rod at the bottom of the blocking ball 74.

[0048] By adopting the above technical solution, different sliders are fixedly connected to the opening and closing wire rope 3 according to the distance between each wastewater sampling cylinder 2, and the sliders are engaged with the wire rope groove 92. During the sampling process, the opening and closing wire rope 3 is pulled upward, and the engagement of the sliders on the opening and closing wire rope 3 with the wire rope groove 92 causes the end of the rotating lever 91 to move upward. Then, through the transmission between the rotating lever 91 and the reverse opening lever 93, the reverse opening lever 93 pushes the blocking ball 74 upward. At this time, the wastewater sample enters from the bottom of the conical connecting cover 71, and finally enters the wastewater sampling cylinder 2 through the fan-shaped hole 73, completing simultaneous sampling and further improving the efficiency of wastewater stratification sampling.

[0049] Furthermore, the end of the rotating lever 91 near the reverse opening lever 93 and the end of the reverse opening lever 93 near the rotating lever 91 are respectively integrally provided with corresponding gear teeth, and the gear teeth at the ends of the rotating lever 91 and the reverse opening lever 93 mesh with each other. When the rotating lever 91 rotates upward, the other end of the reverse opening lever 93 also rotates upward through the meshing between the gear teeth.

[0050] Furthermore, the side of the wire rope slot 92 is provided with an inlet / outlet groove, and the end of the inlet / outlet groove extends to the end of the rotating lever 91 away from the reverse opening lever 93, so that the opening / closing wire rope 3 can be placed into the inside of the wire rope slot 92 through the inlet / outlet groove, or the opening / closing wire rope 3 can be taken out from the inside of the wire rope slot 92.

[0051] Furthermore, the longitudinal section of the wire rope groove 92 is arranged in a stepped shape with a smaller upper section and a larger lower section. The cylindrical stop on the opening and closing wire rope 3 can be engaged with the lower half of the wire rope groove 92 to prevent the opening and closing wire rope 3 from falling off the inside of the wire rope groove 92.

[0052] The top of the opening and closing wire rope 3 is fixedly connected to an anti-slip handle 4. Holding the anti-slip handle 4 allows the opening and closing wire rope 3 to be pulled, preventing the hand from slipping when pulling the opening and closing wire rope 3.

[0053] The working principle of this utility model is as follows: In use, first, take connecting rods 1 of different lengths, several wastewater sampling cylinders 2, and a bottom support frame 8 according to the layering distance. Fit the hollow tube frame 81 under the conical connecting cover 71, and fix the connection point with the locking bolts 83 on the bottom support frame 8. Then, insert both ends of the connecting rod 1 into the lower part of the hollow tube frame 81 and the connecting sleeve 5, respectively, and fix the connection point with bolts. Then, according to the spacing between each hollow tube frame 81, fix the cylindrical stop block fitted on the outside of the opening and closing wire rope 3 to the opening and closing wire rope 3. Then, engage the cylindrical stop block with the wire rope slot 92 at the end of the rotating lever 91. Place the assembled sampling device into the wastewater. After reaching the designated position, hold the anti-slip handle 4 and... Pulling the opening and closing wire rope 3 causes the end of the rotating lever 91 to rotate upwards. After the rotation lever 91 and the reverse opening lever 93 are connected, the end of the reverse opening lever 93 pushes the blocking ball 74 upwards, compressing the compression spring 7. At this time, wastewater of different depths will enter the inner side of the conical blocking cover 72 through the bottom of the conical blocking cover 72, and then enter the wastewater sampling cylinder 2 through the fan-shaped hole 73 on the conical blocking cover 72. After sampling is completed, the opening and closing wire rope 3 is released, and the compression spring 75 will push the blocking ball 74 to automatically reset, so that it blocks the bottom of the conical connecting cover 71. This allows for sampling of wastewater of different depths at one time, improving sampling efficiency. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
