Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filtration device for water quality monitoring. Background Technology

[0002] Water is the source of life, and humans cannot live or produce without it. The quality of drinking water is closely related to human health; therefore, it is necessary to monitor water quality in the ecological environment. Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentration of various pollutants, and their changing trends to evaluate water quality. Water sampling locations include rivers, lakes, and seas. Because some water samples contain a large number of impurities, such as solid impurities, fibers, aquatic plants, and algae, they can easily clog and damage monitoring devices. Therefore, water needs to be filtered before monitoring. Existing water filtration devices generally vibrate or shake the filter screen during the filtration process to improve filtration efficiency. However, when the filter screen vibrates or shakes, it is difficult to clean the impurities adhering to it, causing clogging and affecting the filtration effect. Therefore, a new filtration device for water quality monitoring is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a filtration device for water quality monitoring, thereby solving the aforementioned problems.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A filtration device for water quality monitoring, comprising:

[0006] A filter box, wherein an inlet pipe and an outlet pipe are provided on the filter box;

[0007] A water filtration channel is provided inside the filter box. The water filtration channel includes a filter screen and a vertical plate provided on the side of the filter screen. A guide rail is provided on the vertical plate.

[0008] A shaking component is disposed on one side of the water filter channel to shake the water filter channel;

[0009] The cleaning assembly includes a cleaning brush disposed in the water filtration channel and a pull frame slidably connected to the cleaning brush. The base of the cleaning brush is provided with a first through hole. A crossbar at one end of the pull frame passes through the first through hole and the guide rail, and a crossbar at the other end of the pull frame extends to the outside of the filter box.

[0010] Optionally, the shaking assembly includes a spring disposed on one side of the water filtration channel and a drive motor disposed on the other side of the water filtration channel. One end of the spring is connected to the inner wall of the filter box, and the other end is connected to the upright plate. An eccentric wheel is disposed on the output shaft of the drive motor, and the side of the eccentric wheel is always in contact with the upright plate.

[0011] Optionally, a mounting base is provided on the inner side wall of the filter box, and a motor housing is provided on the mounting base, with the drive motor installed inside the motor housing;

[0012] An action block is provided on the outer wall of the upright plate, and the side of the eccentric wheel is always in contact with the action block.

[0013] Optionally, a guide rod is provided inside the filter box, and both ends of the guide rod are fixed to the inner side wall of the filter box; a guide hole is provided on the upright plate, and the guide rod passes through the guide hole.

[0014] Optionally, the number of through holes is two, and a pull rod is provided on the crossbar at the end of the pull frame away from the cleaning brush; the bristles of the cleaning brush are in contact with the filter screen.

[0018] Compared with existing technologies, this utility model has the following beneficial effects: During filtration, the water to be filtered flows into the filter box from the inlet pipe and into the filter channel. When the water passes through the filter screen, impurities in the water are retained on the filter screen to complete the water filtration. The filtered water flows out of the filter box through the outlet pipe. During this process, the shaking component shakes the filter channel to improve filtration efficiency. At the same time, the cleaning brush shakes together with the filter channel under the push of the upright plate, and the crossbar of the pull frame passes through the base of the cleaning brush, allowing the cleaning brush to slide on the crossbar of the pull frame, that is, the cleaning brush is stationary relative to the filter channel. During cleaning, the operator pulls the pull frame, which moves the cleaning brush in the filter channel to clean the impurities adhering to the filter screen. Thus, even when the filter screen is shaking, it can still clean the impurities adhering to the filter screen while filtering water, improving the filtration effect and efficiency.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1 to 5This utility model provides a filtration device for water quality monitoring, including a filter box 10, a water filtration channel 20, a shaking component 30, and a cleaning component 40. The filter box 10 is rectangular in shape, with an inlet pipe 11 on its side and an outlet pipe 12 on its bottom. The water filtration channel 20 is disposed inside the filter box 10 and includes a filter screen 21 and a vertical plate 22 disposed on the side of the filter screen 21. When the water to be filtered flows into the filter box 10 through the inlet pipe 11, the water flows into the water filtration channel 20, passes through the filter screen 21 to filter out impurities, and the filtered water flows out of the filter box 10 through the outlet pipe 12. The shaking component 30 is disposed on one side of the water filtration channel 20 to shake the water filtration channel 20. It should be noted that the shaking component 30 of this utility model embodiment allows the water filtration channel 20 to shake on a horizontal plane. The cleaning assembly 40 includes a cleaning brush 41 disposed within the water filtration channel 20 and a pull frame 42 slidably connected to the cleaning brush 41. The cleaning brush 41 includes a base and bristles disposed on the base. One end of the bristles is attached to the filter screen 21, and the two end faces of the base are attached to the inner surfaces of the upright plate 22 of the water filtration channel 20. That is, the cleaning brush 41 is engaged within the water filtration channel 20. When the shaking assembly 30 shakes the water filtration channel 20, the water filtration channel 20 causes the cleaning brush 41 to shake synchronously. The upright plate 22 is provided with a guide rail 23, and the base of the cleaning brush 41 is provided with a first through hole 43 corresponding to the guide rail 23. A crossbar at one end of the pull frame 42 passes through the first through hole 43 and the guide rail 23, meaning the water filtration channel 20 and the cleaning brush 41 can slide on the pull frame 42. It should be noted that the width of the pull frame 42 is greater than the amplitude of the shaking of the water filtration channel 20 to prevent the water filtration channel 20 from colliding with the pull frame 42 during shaking. The crossbar at the other end of the pull frame 42 extends outside the filter box 10. When it is necessary to clean the impurities adhering to the filter screen, the operator pulls the crossbar extending outside the filter box 10 to drive the cleaning brush 41 to move within the water filtration channel 20 through the pull frame 42 to clean the impurities adhering to the filter screen.

[0031] Furthermore, a guide rod 36 is provided inside the filter box 10, with both ends of the guide rod 36 fixed to the inner sidewall of the filter box 10. A guide hole 24 is provided on the upright plate 22, through which the guide rod 36 passes, allowing the upright plate 22 to slide on the guide rod 36, i.e., the water filtration channel 20 to slide on the guide rod 36. Optionally, the number of guide rods 36 is not less than two, so that the upright plate 22 can only slide on the guide rod 36 and cannot rotate around it. In this embodiment, there are two guide rods 36, and correspondingly, there are two sets of guide holes 24, located at both ends of the water filtration channel 20.

[0032] Furthermore, the shaking assembly 30 includes a spring 31 disposed on one side of the water filter channel 20 and a drive motor disposed on the other side of the water filter channel 20. One end of the spring 31 is connected to the inner wall of the filter box 10, and the other end is connected to the outer side of the upright plate 22. An eccentric wheel 32 is disposed on the output shaft of the drive motor, and the side of the eccentric wheel 32 is always in contact with the upright plate 22. In this embodiment of the present invention, the spring 31 is always in a compressed state, that is, the water filter channel 20 is always subjected to the elastic force of the spring 31, which makes the water filter channel 20 always tend to move towards the eccentric wheel 32. Therefore, when the drive motor drives the eccentric wheel 32 to rotate, the upright plate 22 on one side of the water filter channel 20 is always in contact with the eccentric wheel 32, and during the rotation of the eccentric wheel 32, the water filter channel 20 makes a periodic reciprocating motion, thereby realizing the shaking of the water filter channel 20.

[0033] Furthermore, a mounting base 33 is provided on the inner wall of the filter box 10, and a motor housing 34 is provided on the mounting base 33, with the drive motor installed inside the motor housing 34. Optionally, the mounting base 33 is bolted to the inner wall of the filter box 10, and the output shaft of the drive motor extends to the outside of the motor housing 34. An actuating block 35 is provided on the outer wall of the upright plate 22, and the side of the eccentric wheel 32 is always in contact with the actuating block 35, that is, the side of the eccentric wheel 32 is always in contact with the upright plate 22 through the actuating block 35.

[0034] Furthermore, there are two through holes, and correspondingly, there are two crossbars on the pull frame 42 near the cleaning brush 41, so that the cleaning brush 41 can only slide on the crossbars and cannot rotate around them. A pull rod 44 is provided on the crossbar at the end of the pull frame 42 away from the cleaning brush 41 to facilitate operator operation.

[0035] Optionally, a first water intake chamber 13 is provided above the water filtration channel 20, and the first water intake chamber 13 is fixed to the inner wall of the filter box 10. The first water intake chamber 13 is funnel-shaped, and the cross-section of the outlet of the first water intake chamber 13 is rectangular and located inside the water filtration channel 20, so as to guide the water to be filtered to the water filtration channel 20. It should be noted that the width of the outlet of the first water intake chamber 13 is smaller than the width of the water filtration channel 20, and the water filtration channel 20 does not contact the first water intake chamber 13 during shaking. A second water intake chamber 25 is provided on the bottom surface of the filter screen plate 21. The outlet of the second water intake chamber 25 is tubular and is connected to the outlet pipe 12 through a flexible hose.

[0036] Furthermore, one end of the water filtration channel 20 is open, and the filter box 10 is equipped with a drawer-type dirt collection box 50 corresponding to the opening of the water filtration channel 20. A handle 51 is provided on the side of the dirt collection box 50. During cleaning, the impurities adhering to the filter screen are pushed to one end of the water filtration channel 20 by the cleaning brush 41 and fall into the dirt collection box 50 through the opening at one end of the water filtration channel 20.

[0037] Furthermore, a transparent glass plate 14 and a motor switch 15 are provided on one side of the filter box 10, allowing the operator to observe the impurities on the filter screen 21 through the transparent glass plate 14. A second through-hole corresponding to the pull frame 42 and a third through-hole for the sludge collection box 50 to enter and exit are provided on one side of the filter box 10. Support feet 16 are also provided on the filter box 10. Optionally, a limit tube (not shown) is provided on the second through-hole, through which the crossbars on both sides of the pull frame 42 pass, thereby improving the stability of the pull frame 42.

[0038] This utility model discloses a filtration device for water quality monitoring. Specifically, during filtration, water to be filtered flows from the inlet pipe 11 into the filter box 10 and then into the filter channel 20. When the water passes through the filter screen 21, impurities in the water are retained on the filter screen 21, thus completing the water filtration. The filtered water flows out of the filter box 10 through the outlet pipe 12. During this process, the shaking assembly 30 shakes the filter channel 20 to improve filtration efficiency. Simultaneously, the cleaning brush 41, pushed by the upright plate 22, shakes together with the filter channel 20, and the crossbar of the pull frame 42 passes through the base of the cleaning brush 41, allowing the cleaning brush 41 to slide on the crossbar of the pull frame 42, meaning the cleaning brush 41 is stationary relative to the filter channel 20. During cleaning, the operator pulls the pull frame 42, which drives the cleaning brush 41 to move within the water filtration channel 20 to remove impurities adhering to the filter screen. This ensures that even when the filter screen plate 21 is shaking, it can still clean the impurities adhering to the filter screen, thus improving the filtration effect and efficiency.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
