Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically, to a sewage sample collection device. Background Technology
[0002] Urban wastewater treatment systems typically involve sewers, intermediate wastewater lift pump stations, and wastewater treatment plants. Water quality testing is an essential component of wastewater treatment plants and intermediate wastewater lift pump stations. Within water quality testing, water sampling is equally crucial. The quality of the water sample determines its representativeness and reliability, thus providing a stable foundation for subsequent processes.
[0003] In existing technologies, some sewage sampling devices are typically fixed installations, meaning the sampling device is permanently installed at the sewage sampling point. Staff only need to collect the sewage samples obtained by the sampling device. However, this sewage sampling method results in the sampling device being in constant contact with sewage, causing impurities, bacteria, and algae in the sewage to adhere to the surface of the sampling device. During the sewage sampling process, these contaminants are mixed into the sample under the impact of the sewage flow, causing varying degrees of error in the sewage sample test results. This leads to unreasonable and unscientific sewage sampling. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a wastewater sample collection device that is easy to assemble and disassemble and ensures effective sample collection, thereby solving the problems mentioned in the background technology.
[0006] (II) Technical Solution
[0007] To achieve the advantages of easy and quick assembly and disassembly, and to ensure the effectiveness of water sample collection, the specific technical solution adopted by this utility model is as follows: A sewage water sample collection device includes a sewage tank. Two guide frames are fixed at the sewage discharge channel of the sewage tank, and a sampling horn is slidably installed between the two guide frames. A vertical rod is welded to the top surface of the sampling horn, and a threaded elbow connected to the sampling horn is provided on one side of the vertical rod. A sewage sampling cylinder is threadedly installed at the end of the threaded elbow away from the sampling horn. A guide plate is welded to the inner wall of the sampling horn corresponding to the threaded elbow. A T-shaped slider is welded to the left and right sides of the sampling horn respectively. T-shaped grooves are opened on the facing surfaces of the two guide frames, and the T-shaped sliders are slidably connected to the T-shaped grooves of the guide frames.
[0008] Furthermore, an installation assembly is welded to the side of the guide frame facing the inner wall of the sewage tank. The installation assembly consists of an installation plate with screw holes, a connecting horizontal plate, and an oblique reinforcing rib. The connecting horizontal plate of the installation assembly is welded to the oblique reinforcing rib.
[0009] Furthermore, the wastewater sampling tube has an integrally formed threaded nozzle at its port, and the threaded nozzle is threadedly connected to the threaded portion of the threaded elbow.
[0010] Furthermore, the top of the guide frame is provided with a T-shaped opening that communicates with the T-shaped groove.
[0011] Furthermore, the pole is vertically positioned relative to the sampling horn, and a flat, round handle is welded to the top of the pole.
[0012] Furthermore, the size of the sampling horn is matched with the gap between the two guide frames, and the large opening of the sampling horn is set towards the direction of the sewage flow.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a wastewater sample collection device, which has the following beneficial effects:
[0015] This invention employs a guide frame and a sampling horn installed at the sewage discharge channel of a sewage tank. By extending the sampling horn between two guide frames, the T-shaped slider of the sampling horn slides into a T-shaped groove on the facing surfaces of the two guide frames. As the operating rod moves the sampling horn downward, it becomes submerged in the sewage. During the sewage flow phase, the sewage entering the sampling horn is guided to the threaded bend by the guide plate and forced into the sewage sampling cylinder threaded to the threaded bend by the impact of the sewage flow, thus completing the collection of sewage samples. Compared with existing technologies, this invention uses a sliding sampling horn, which facilitates quick installation and removal of the sampling horn while meeting the requirements for sampling flowing sewage. This facilitates cleaning of the sampling horn and avoids contamination by impurities, bacteria, and algae in the sewage, ensuring the effectiveness of water sample collection. Furthermore, a single sampling horn can be used to collect water samples from several sampling points, greatly facilitating sewage sampling. Attached Figure Description

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0024] According to an embodiment of the present invention, a wastewater sample collection device is provided.
[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a wastewater sampling device according to an embodiment of the present invention includes a wastewater tank 1. Two guide frames 2 are fixed at the discharge channel of the wastewater tank 1, and a sampling horn 4 is slidably installed between the two guide frames 2. A vertical rod 6 is welded to the top surface of the sampling horn 4, and a threaded elbow 7 connected to the sampling horn 4 is provided on one side of the vertical rod 6. A wastewater sampling cylinder 8 is threadedly installed at the end of the threaded elbow 7 away from the sampling horn 4. A guide plate 9 is welded to the inner wall of the sampling horn 4 corresponding to the threaded elbow 7. A T-shaped slider 5 is welded to the left and right sides of the sampling horn 4 respectively. T-shaped grooves 10 are opened on the facing surfaces of the two guide frames 2. The T-shaped sliders 5 are slidably connected to the T-shaped grooves 10 of the guide frames 2. The two guide frames 2 form a group and can be installed at several sampling nodes of the wastewater tank 1. A single sampling horn 4 is used to realize the water sample collection work at several sampling nodes, which greatly facilitates the wastewater sampling work. For water bodies with still wastewater, the vertical rod 6 can be manipulated to swing to collect water samples. At this time, the sampling horn 4 does not need to be used in conjunction with the guide frame 2.
[0026] In one embodiment, the guide frame 2 is welded to the inner wall of the sewage tank 1 with an installation component 3. The installation component 3 consists of an installation plate with screw holes, a connecting horizontal plate 12, and an oblique reinforcing rib 13. The connecting horizontal plate 12 and the oblique reinforcing rib 13 of the installation component 3 are welded together. The installation component 3 facilitates the fixed installation of the guide frame 2 and enhances the overall structural strength through the connecting horizontal plate 12 and the oblique reinforcing rib 13. Both the guide frame 2 and the installation component 3 are made of stainless steel, which is resistant to sewage corrosion and extends service life.
[0027] In one embodiment, a threaded nozzle 11 is integrally formed at the port of the sewage sampling tube 8, and the threaded nozzle 11 is threadedly connected to the threaded portion of the threaded elbow 7. The threaded nozzle 11 facilitates the threaded connection with the threaded portion of the threaded elbow 7, making it convenient to replace the sewage sampling tube 8.
[0028] In one embodiment, the top of the guide frame 2 is provided with a T-shaped opening that communicates with the T-shaped groove 10. That is, the top of the T-shaped groove 10 of the guide frame 2 is an open structure, and the bottom of the T-shaped groove 10 of the guide frame 2 is a closed structure to prevent the sampling horn 4 from falling off.
[0029] In one embodiment, the pole 6 is vertically positioned relative to the sampling horn 4, and a flat, round handle is welded to the top of the pole. The pole 6 and the flat, round handle facilitate the mounting and dismounting of the sampling horn 4.
[0030] In one embodiment, the size of the sampling horn 4 is matched with the gap between the two guide frames 2, and the large opening of the sampling horn 4 is set towards the water flow direction of the sewage tank 1. That is, the gap between the two guide frames 2 meets the installation requirements of the sampling horn 4. The sewage flow of the sewage tank 1 enters through the large opening of the sampling horn 4 and exits through the small opening of the sampling horn 4. This sampling method makes it easy for the sewage flow to accumulate in the sampling horn 4, providing a basis for water sample collection.
[0031] Working principle: First, the mounting components 3 of the two guide frames 2 are bolted through, so that the two guide frames 2 are symmetrically installed at the sewage discharge channel of the sewage tank 1, and the distance between the two guide frames 2 meets the installation requirements of the sampling horn 4. When collecting sewage samples, the sampling horn 4 is extended between the two guide frames 2, causing the T-shaped slider 5 of the sampling horn 4 to slide and connect with the T-shaped groove 10 opened on the facing surfaces of the two guide frames 2. As the operating rod 6 moves the sampling horn 4 downward, the sampling horn 4 is submerged in the sewage. During the sewage flow stage, the sewage entering the sampling horn 4 is guided to the threaded bend 7 by the guide plate 9, and under the impact of the sewage flow, the sewage is forced into the sewage sampling cylinder 8 threadedly connected to the threaded bend 7, thus completing the collection of sewage samples. After the sewage samples are collected, the sampling horn 4 of the two guide frames 2 is pulled out by the rod 6, and then the sewage sampling cylinder 8 threadedly installed on the sampling horn 4 is rotated. The sampling horn 4 is then rinsed and a new sewage sampling cylinder 8 is replaced. Finally, the sampling horn 4 is transferred to the next water sample collection node for sewage sample collection.
