Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, specifically to a sample oil removal filter suitable for water quality analyzers. Background Technology

[0002] With the continuous development of the environmental protection and petrochemical industries, process samples are becoming increasingly complex, and industrial wastewater often contains oil. In order to avoid the pollution and impact of oily wastewater on instrument measurements, oil removal filtration before measurement is particularly important. This oil removal filter was designed to facilitate water body detection and analysis.

[0003] Existing sample oil removal filters for water quality analyzers, although equipped with drain ports to expel oil, still retain a layer of oil on the outer surface of the filter element due to its adhesive properties. Over time, this oil buildup on the filter element's pores can clog the filtration area, reducing overall filtration efficiency. This means the filter takes longer to process the same amount of liquid, or the processed liquid may contain more unfiltered impurities, necessitating filter element disassembly for maintenance – a relatively cumbersome process. Therefore, the design of sample oil removal filters for water quality analyzers requires a cleaning mechanism that effectively cleans the filter element without disassembly, improving overall practicality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a sample oil removal filter suitable for water quality analyzers, so as to solve the technical problem that traditional filters are more troublesome to clean.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample oil removal filter suitable for a water quality analyzer, comprising a filter body, the filter body including a shell, a first mounting block disposed in the middle of the outer side of the shell, a magnetic ring threadedly connected to the bottom of the first mounting block, the magnetic ring being slidably connected to the shell;

[0006] The filter body has a filter chamber inside, and a cleaning mechanism is engaged and slidable on the inner wall of the filter chamber. The cleaning mechanism includes a magnetic ring, and a side groove is opened on the outer side of the magnetic ring. Multiple vibration motors are arranged inside the side groove. The vibration motors are arranged in a sheet-like structure. A brush is arranged on the inner side of the magnetic ring. The magnetic ring drives the magnetic ring to move through magnetic attraction.

[0007] The vibration motor is used to drive the brush to vibrate, and the brush is used to clean the dirt in the outer filter layer.

[0008] The outer surface of the housing is provided with a viewing port, which is used to observe the dirt condition of the outer filter layer.

[0009] By adopting the above technical solution, the outer shell provides robust protection for the filter body, ensuring that the internal components are protected from external impacts and damage, while the design of the first mounting block and magnetic ring in the middle of the outer side makes the driving of the cleaning mechanism more convenient and efficient.

[0010] Furthermore, the top of the magnetic ring is provided with a wiring port, and a circuit wire is detachably connected to one side of the wiring port. The circuit wire is a miniature coaxial cable.

[0016] Furthermore, internal threads are provided on both the upper and lower inner walls of the filter chamber, and sealing grooves are respectively provided at the top and bottom of the two internal threads.

[0017] By adopting the above technical solution, the internal thread design facilitates the installation and disassembly of the filter mechanism and the bottom cover, and the cooperation between the sealing groove and the sealing ring enhances the sealing performance of the filter chamber and prevents liquid leakage.

[0018] Furthermore, a bottom cover is provided below one of the sealing grooves, and a lower threaded ring is provided on the top of the bottom cover. The bottom cover is screwed to the internal thread through the lower threaded ring, and a sealing ring is provided on the outside of the lower threaded ring. The sealing ring engages with the sealing groove.

[0019] By adopting the above technical solution, the bottom cover is tightly connected to the internal thread through the lower threaded ring, ensuring the stability of the structure. Moreover, the engagement of the sealing ring and the sealing groove further enhances the sealing effect and prevents liquid leakage during the filtration process.

[0020] Furthermore, a filter mechanism is provided above another internal thread. The filter mechanism includes a second mounting block, an upper threaded ring is provided at the bottom of the second mounting block, and a sealing ring is provided on the outer side of the upper threaded ring.

Moreover, the engagement of the sealing ring on the outside of the upper threaded ring with the sealing groove ensures a good seal between the filter mechanism and the filter chamber.

[0022] Furthermore, an outer filter layer is installed at the bottom of the second mounting block, and a filter element is provided on the inner side of the outer filter layer, with a filter tube opened on the inner side of the filter element.

[0023] By adopting the above technical solution, the outer filter layer first intercepts large particulate impurities, protecting the internal filter element from clogging. Moreover, the combination of the filter element and the filter tube further improves the filtration effect and ensures the cleanliness of the output liquid.

[0024] Furthermore, the bottom of the filter tube is provided with a connector, and the bottom of the bottom cover is provided with a sample outlet, which is engaged with the connector.

[0025] By adopting the above technical solution and the snap-fit ​​design of the interface and the sample outlet, it is ensured that the filtered liquid can flow out smoothly and without leakage. Moreover, this design simplifies the liquid collection process and improves work efficiency.

[0026] Furthermore, an oil drain is provided on one side of the sample outlet, and a liquid inlet is provided on the other side of the filter body.

[0027] By adopting the above technical solution, the oil drain port can be conveniently discharged during the filtration process, avoiding the accumulation of oil in the filter. Moreover, the design of the liquid inlet facilitates the input of the liquid to be filtered, thus improving the filtration efficiency.

[0047] See Figure 1 , Figure 2 , Figure 3 An outer filter layer 202 is installed at the bottom of the second mounting block 201. A filter element 203 is provided on the inner side of the outer filter layer 202. A filter tube 204 is opened on the inner side of the filter element 203. The outer filter layer 202 first intercepts large particulate impurities and oil stains, extending the service life of the filter element 203. The design of the filter element 203 and the filter tube 204 provides further fine filtration, ensuring the cleanliness of the output liquid.

[0048] See Figure 1 , Figure 2 , Figure 3 The bottom of the filter tube 204 is provided with a connector 205, and the bottom of the bottom cover 3 is provided with a sample outlet 303.

The oil drain port 304 allows the oil intercepted during the filtration process to be easily discharged, avoiding the accumulation of oil in the filter. Moreover, the design of the liquid inlet 108 facilitates the input of the liquid to be filtered and improves the filtration efficiency.

[0050] The implementation principle of this utility model is as follows: First, the bottom cover 3 needs to be screwed to the lower internal thread 103 inside the filter body 1 via the lower threaded ring 301 on its top. Ensure that the sealing ring 302 is correctly engaged in the lower sealing groove 104 to achieve a good sealing effect. Then, the upper threaded ring 206 at the bottom of the second mounting block 201 of the filter mechanism 2 is screwed to the upper internal thread 103 inside the filter body 1. Similarly, ensure that the sealing ring 302 is correctly engaged in the upper sealing groove 104. Subsequently, one end of the circuit wire 406 is connected to the vibration motor 403 on the magnetic ring 401 through the wiring port 405. Then, the other end of the circuit wire 406 is passed through the wiring port 407 on the housing 101 and connected to the external power supply. The magnetic ring 401 of the cleaning mechanism 4 is engaged and slid into the inner wall of the filter chamber 102 to ensure that the magnetic ring 401 can move under the magnetic attraction of the magnetic ring 107 on the outside of the housing 101. At the same time, the magnetic ring 107 is threaded to the bottom of the first mounting block 106 and slidably connected to the housing 101 to ensure that the position of the magnetic ring 107 can be correctly aligned and drive the magnetic ring 401.

[0051] When using the filter mechanism 2, if it is necessary to clean it, the vibration motor 403 can be started to drive the brush 404 to vibrate. Then the operator can observe the cleanliness of the outer filter layer 202 through the viewing port 105 and adjust the position of the magnetic ring 107 or the working frequency of the cleaning mechanism 4 as needed.
