Description

Technical Field

[0001] The utility model belongs to the technical field of water quality safety detection, and in particular relates to a capacitive sheet probe filtering device. Background Art

[0002] With the rapid development of modern science and technology, antibiotics have played an indispensable role in our daily lives, especially in the treatment and prevention of diseases in humans and animals. However, the actual absorption rate of antibiotics in humans and animals is relatively low, and a large amount of antibiotics enter the environment through excrement in an unchanged form. Water bodies have become one of the main destinations of these antibiotics. Despite sewage treatment, some antibiotics cannot be completely removed and remain in the water, which not only causes water pollution, but may also pose a threat to human health and safety.

[0003] Capacitive sensors have the characteristics of good temperature stability, simple structure, strong adaptability, and good dynamic response. However, such sensor plates are prone to "parasitic capacitance" with surrounding objects, thus affecting the detection accuracy. In order to eliminate this "parasitic capacitance" as much as possible to improve the detection accuracy of antibiotic residues in water, filtering equipment is needed to remove various sizes of impurities such as mud, algae, heterotrophic microorganisms and protozoa in the water. There is usually a problem with the detection equipment on the market: its filter is difficult to disassemble, which not only takes a lot of time for users, but also reduces the filtering effect because it is difficult to clean and replace. In order to solve this problem, we designed a new type of capacitive sheet probe filtering device. This device can initially filter out larger impurities such as mud, stones, leaves, etc. in the water, and further remove smaller impurities such as algae, heterotrophic microorganisms, and protozoa. This not only improves the filtering effect, but also protects the sensor probe from damage. In addition, this filtering device is easy to install and can be disassembled, cleaned and replaced at any time, which provides convenience for users and indicates that it has broad application prospects. Utility Model Content

[0004] In order to solve the above problems, the utility model designs a detachable capacitive sheet probe filtering device with good filtering effect and simple installation, which is used for filtering impurities of different sizes in water when detecting antibiotic residues in water.

[0005] In order to achieve the purpose of the utility model, the utility model adopts the following technical solutions:

[0006] The capacitive sheet probe filtering device includes a tube cover, a probe mounting seat, a capacitive sheet probe, screws, nuts, and filter cotton; the tube cover is provided with a through hole on the top, a filter hole on the side, and a rotating buckle at the bottom; the probe mounting seat is provided with an installation groove for installing the sheet probe on the inner side, and a rotating buckle groove for installing the tube cover is provided at the bottom.

[0007] The filter holes on the top side of the cylinder cover are consistent in size and evenly distributed.

[0008] The capacitive sheet probe is connected to the cylinder cover by bolts. The bolt connection is divided into two parts, a screw and a nut. The screw and the nut are both one, and the screw has a through hole axially opened to penetrate the signal line.

[0009] The capacitive sheet probe is cooperatively connected with the mounting groove inside the probe mounting seat.

[0010] The filter screen is wound around the side of the probe mounting seat, and the probe mounting seat is connected with the cylinder cover by rotating buckle cooperation through a rotating buckle groove at the bottom.

[0011] Preferably, the filter holes on the side of the barrel cover and the filter holes on the side of the probe mounting seat can filter larger impurities in the water.

[0012] Preferably, the filter cotton can filter smaller impurities in the water.

[0013] Preferably, the device is cylindrical, so that when the water body needs to be stirred before the sensor probe detects, it is not easy to have a stirring dead angle.

[0014] In summary, the beneficial effects of the present invention are:

[0015] 1. The capacitive sheet probe filter device is provided with filter holes and filter cotton. The filter holes can be used to initially filter out larger impurities such as stones, leaves, and weeds in the water body, and the filter cotton can be used to further filter out smaller impurities such as algae, heterotrophic microorganisms, and protozoa in the water body, thereby enhancing the filtering effect of the device on the water body.

[0016] 2. The capacitive sheet probe filter device is cylindrical, which not only has a good protective effect on the sensor probe, but also ensures the immersion depth of the capacitive sheet probe in the water body.

[0017] 3. The capacitive sheet probe filter device has a compact structure, good stability, light weight, simple installation and disassembly, and can be cleaned and replaced at any time. BRIEF DESCRIPTION OF THE DRAWINGS
