Description

Technical Field

[0001] The utility model belongs to the technical field of liquid detection, and particularly relates to a liquid detection sample processing device. Background Art

[0002] Due to environmental requirements, sewage needs to be detected before being discharged. After sampling, the sewage sample cannot be directly detected and needs to be processed. The existing method is to filter it through non-woven fabric, then precipitate it, and take the upper liquid for detection. This method takes a long time and has low work efficiency.

[0003] In the related art (publication number: CN209911087U), a sample processing device for liquid detection is disclosed, including: a mounting frame, a mud-water separator, a liquid buffer device, a spiral filter, and a power driving device. A liquid buffer device is arranged at the upper end of the mud-water separator. The lower end of the spiral filter is threadedly connected to the liquid buffer device. A power driving device is arranged at the upper end of the spiral filter. A liquid inlet is arranged on the side wall of the spiral filter. A liquid outlet is arranged at the lower end of the mud-water separator. The liquid sample enters through the liquid inlet and sequentially passes through the spiral filter, the liquid buffer device, and the mud-water separator and is discharged through the liquid outlet. Both the mud-water separator and the spiral filter are connected to the mounting frame through connecting rods. The utility model preprocesses sewage through the spiral filter to remove large-particle impurities. The filtered liquid flows into the mud-water separator through the through holes on the auger blades for mud-water separation, and high-pressure gas is injected into the stamping interface to accelerate the separation rate.

[0004] However, there are still certain drawbacks when the existing liquid detection and processing equipment is in use. Since the components in the liquid are complex, the density and properties of different layers are different. It is difficult for the existing liquid detection preprocessing equipment to directly sample different layers specifically. If the sampler is inserted from top to bottom, the ports of the sampler will be contaminated successively due to passing through multiple layers, making it difficult to directly sample and detect the liquid at the bottom or middle layer. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art that it is difficult for the existing liquid detection preprocessing equipment to directly sample different layers specifically, if the sampler is inserted from top to bottom, the ports of the sampler will be contaminated successively due to passing through multiple layers, making it difficult to directly sample and detect the liquid at the bottom or middle layer, etc., the utility model provides a liquid detection sample processing device, which is provided with multiple layers, and corresponding guide pipes and sampling pipes are respectively arranged for each layer, so as to be able to directly sample the liquid of different layers specifically. Each sampling port is independently arranged, and the liquid at the bottom or middle layer can be directly sampled and detected, and the sampling can better ensure the representativeness of the sample. The specific technical solution is as follows:

[0014] First, aiming at the problem that it is difficult for existing liquid detection pretreatment equipment to achieve targeted direct sampling of multiple layers. If the sampler is inserted deeply from top to bottom, the ports of the sampler will be contaminated successively due to passing through multiple layers, making it difficult to directly sample and detect the liquid at the bottom or middle layer. The present utility model is provided with multiple layers, and corresponding guiding tubes and sampling tubes are respectively arranged for each layer, which can directly and specifically sample the liquid of different layers.

[0021] The following further describes the present utility model in conjunction with specific implementation cases and attached Figures 1 to 3 drawings, but the present utility model is not limited to these embodiments.

[0022] Refer to Figures 1 to 3As shown in the figure, a liquid detection sample processing device includes a first layer 1, and multiple second layers 2 are arranged above the first layer 1. In this embodiment, there are three second layers 2. A third layer 3 is arranged above the top second layer 2. The third layer 3, multiple second layers 2, and the first layer 1 form a connected cavity for sample processing. Sampling components are respectively arranged on the side walls of the first layer 1 and multiple second layers 2. The sampling components are arranged obliquely upward. Each group of sampling components includes a guiding tube 4, and a sampling tube 5 is pluggably arranged in the guiding tube 4. When sampling the sample at each second layer 2, with the help of a pumping tool, the sample is pumped from the sampling tube 5 at the corresponding position of the second layer 2, and the sample at the second layer 2 can be directly pumped. Multiple support arms 6 are arranged at the bottom end of the first layer 1, and a discharging valve 7 is connected to the bottom end of the first layer 1. Through the discharging valve 7, the sample at the first layer 1 can be directly pumped and processed, thereby enabling independent and separate sampling of multiple layers of samples.

[0023] Refer to Figure 1 As shown in the figure, observation windows 8 are respectively arranged on the side walls of the first layer 1 and multiple third layers 3. Through the observation windows 8, the inner cavity conditions of the second layer 2 at each position can be observed.

[0024] Refer to Figure 2 and Figure 3 As shown in the figure, a screening bin 9 is rotatably arranged at the top end of the third layer 3. Mounting plates 10 are respectively installed on the left and right side walls of the screening bin 9. The bottom ends of the mounting plates 10 are respectively rotatably connected to drive shafts 11. A gear 12 is fixedly installed on the outer wall of the drive shaft 11. A moving frame 13 is rotatably arranged on the outer wall of the drive shaft 11. And a toothed ring 18 is fixedly installed at the top end of the side wall of the third layer 3. The gear 12 is meshed with the toothed ring 18. By driving the drive shaft 11 to drive the gear 12 to rotate synchronously, since the gear 12 is meshed with the toothed ring 18, the rotating gear 12 causes the moving frame 13 to rotate circumferentially along the limiting ring 17, thereby realizing the rotation of the mounting plate 10 and the screening bin 9 relative to the third layer 3. Thus, during the rotation of the screening bin 9, impurity removal treatment of the liquid sample is realized, and it is avoided that impurities enter the second layer 2 and the first layer 1 downward and affect subsequent sample sampling.

[0025] A groove 14 is formed at the bottom end of the moving frame 13. Multiple mounting rods 16 are fixedly installed on the side wall of the third layer 3. A limiting ring 17 is fixedly installed at the top end of the mounting rod 16, and the limiting ring 17 is slidably embedded in the inner cavity of the groove 14. When the moving frame 13 moves, it can cause the groove 14 to move along the limiting ring 17 to limit the moving direction of the moving frame 13.

[0026] In addition, a motor 15 is installed on the top of one of the mounting plates 10, and the output end of the motor 15 is connected to one of the driving shafts 11. The motor 15 can drive the driving shaft 11 to rotate, thereby causing the gear 12 to engage with the ring gear 18 to rotate.

[0027] In addition, the guide tube 4 is arranged at an inclination angle ranging from 60 degrees to 80 degrees. The guide tube 4 in this range can prevent the liquid in the inner cavity of the second level 2 from overflowing and can ensure normal sample collection.

[0028] It is worth noting that the motor 15 in the present application adopts a self-locking motor with a lockable output end commonly used on the market. When the motor stops operating, the output end can self-lock and will not rotate under external force. The above-mentioned existing components will not be described in detail here.

[0029] The working principle of a liquid detection sample processing device in this embodiment is as follows:

[0030] The liquid sample is cleaned by means of the screening chamber 9. The driven shaft 11 connected to the output end thereof is driven to rotate by the turned-on motor 15, so as to drive the driven shaft 11 and the gear 12 to rotate synchronously. Since the gear 12 is meshed and connected with the ring gear 18, the rotating gear 12 causes the movable frame 13 to rotate circumferentially along the limit ring 17, thereby realizing the rotation of the mounting plate 10 and the screening chamber 9 relative to the third level 3, thereby realizing the cleaning of the liquid sample by the screening chamber 9 during the rotation process, and preventing the impurities from entering the second level 2 and the first level 1 downward to affect the subsequent sample sampling;

[0031] When sampling each sample at the second level 2, the sample is extracted from the sampling tube 5 at the corresponding position of the second level 2 by means of an extraction tool, so that the sample at the second level 2 can be directly extracted, and the sample at the first level 1 can be directly extracted through the discharge valve 7, thereby realizing independent sampling of multiple layers of samples;

[0032] The utility model is provided with multiple levels, and the multiple levels are respectively provided with corresponding guide tubes 4 and sampling tubes 5, which can directly sample the liquids of different levels in a targeted manner. Each sampling port is independently provided, and the bottom or middle layer of the liquid is directly sampled and tested. The sampling can better ensure the representativeness of the sample, and there is no need for the sampler to go deep into the inner cavity of the first level 1 from top to bottom for sampling, so as to avoid the sampler being contaminated by the liquids of other levels. The screening bin 9 can screen out impurities in the inner cavity liquid during the rotation process. Compared with the static method of screening out impurities, it can better ensure that the impurities in the liquid are fully screened out.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
