[0002] With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the environment are constantly increasing, and the environmental pollution caused by wastewater discharge is becoming increasingly serious. In order to avoid further pollution of the environment by wastewater, it is generally necessary to detect the wastewater before it is discharged. And the detection requires sampling the wastewater.

Therefore, it is necessary to separate them through a solid-liquid separator before detection.

Specific embodiments
[0056] The present utility model will be further described below with reference to the accompanying drawings:
[0057] In this embodiment:
[0058] Please refer to Figures 1-6 , in this embodiment: A solid-liquid separation device for water quality detection includes: a separation box 1, a protective housing 8, a separation structure, and a clamping structure.
[0059] In this embodiment, the protective housing 8 is arranged directly above the separation box 1 to prevent wastewater from splashing.
[0060] In this embodiment, a box door is installed on the surface of the separation box 1, and a liquid outlet pipe 10 is installed below the inside of the separation box 1; a liquid inlet pipe 9 is installed inside the protective housing 8, and the water outlet end of the liquid inlet pipe 9 faces the inside of the third separation member 7; the liquid inlet pipe 9 is located behind the moving device and the dredging device and will not hinder the moving device and the dredging device.
[0061] The separation structure is arranged inside the separation box 1 for solid-liquid separation of wastewater; the separation structure includes: a first separation member 5, a second separation member 6, and a third separation member 7, and the second separation member 6 is arranged between the first separation member 5 and the third separation member 7.
[0062] In this embodiment, as Figure 3As shown, the first separating member 5, the second separating member 6, and the third separating member 7 are connected by a rod having a cylindrical shape.
[0063] The surface of the first separating member 5 is provided with first filtering holes, the surface of the second separating member 6 is provided with second filtering holes, and the surface of the third separating member 7 is provided with third filtering holes.
[0064] In this embodiment, by operating the separating structure, the first separating member 5, the second separating member 6, and the third separating member 7 are rotated, so that the sewage moves outward by centrifugal force, while the solid particles remain in the middle. At the same time, the first filtering holes, the second filtering holes, and the third filtering holes with different inner diameters are used for hierarchical filtration, so as to achieve solid-liquid separation. At the same time, the addition of centrifugal force can improve the separation speed.
[0065] The clamping structure is connected to the upper part of the outer wall of the first separating member 5 for restricting the position of the first separating member 5.
[0066] In this embodiment, the position of the first separating member 5 can be fixed by the clamping structure to prevent the first separating member 5 from separating from the separating structure when it rotates.
[0067] As Figure 2 and Figure 3 shown, the separating structure further includes: a filter plate 2, a plurality of sets of clamping blocks 3, and a first motor 4.
[0068] Among them, the upper end surface of the filter plate 2 is provided with a first annular groove, a second annular groove, and a third annular groove, so that the bottom end of the first separating member 5 can be inserted into the first annular groove, the bottom end of the second separating member 6 can be inserted into the second annular groove, and the bottom end of the third separating member 7 can be inserted into the third annular groove; through holes are provided on the surface of the filter plate 2.
[0069] In this embodiment, when the filter plate 2 rotates, it will drive the first separating member 5, the second separating member 6, and the third separating member 7 to rotate synchronously.
[0070] A plurality of sets of clamping blocks 3 are arranged in the notches provided at the bottom ends of the first separating member 5, the second separating member 6, and the third separating member 7, and are slidably connected to the first separating member 5, the second separating member 6, and the third separating member 7.
[0071] In this embodiment, by inserting the clamping blocks 3 into the notches, the rotation of the first separating member 5, the second separating member 6, and the third separating member 7 is driven.
[0072] The output end of the first motor 4 is fixedly connected to the center of the filter plate 2.
[0073] In this embodiment, the model of the first motor 4 is selected according to actual needs as long as it meets the working conditions.
[0074] The inner diameter of the second filtering hole is smaller than that of the first filtering hole and larger than that of the third filtering hole; the inner diameter of the third filtering hole is the same as that of the through hole.
[0075] When performing solid-liquid separation, first insert the first separating member 5, the second separating member 6, and the third separating member 7 into the first annular groove, the second annular groove, and the third annular groove respectively, so that the clamping block 3 is inserted into the notch. At this time, start the first motor 4, and the output end of the first motor 4 drives the filter plate 2 to rotate. The filter plate 2 drives the first separating member 5, the second separating member 6, and the third separating member 7 to rotate synchronously through multiple groups of clamping blocks 3. Using centrifugal force, the sewage moves outward, while the solid particles will remain in the middle. At the same time, the first filtering hole, the second filtering hole, and the third filtering hole with different inner diameters are used for grading filtration, so as to achieve solid-liquid separation. At the same time, the addition of centrifugal force can improve the separation speed.
[0076] As Figure 2 and Figure 6 shown, the clamping structure includes: a collar 33, a clamping member 34, and a third elastic member 35.
[0077] Specifically, the collar 33 is sleeved on the upper outer surface of the first separating member 5 and is rotatably connected to the first separating member 5.
[0078] In this embodiment, the collar 33 can support the rotation of the first separating member 5, and at the same time, the collar 33 also restricts the vertical movement of the first separating member 5.
[0079] Both sides of the collar 33 are provided with clamping ports; one end of the clamping member 34 extends into the clamping ports.
[0080] In this embodiment, by inserting the clamping member 34 into the clamping ports, the movement of the collar 33 is restricted.
[0081] The third elastic member 35 is composed of a third spring and a third baffle. The third spring is arranged between the third baffle and the separation box 1 and is sleeved on the outer surface of the clamping member 34; the inner wall of the third baffle is fixedly connected to the clamping member 34.
[0082] In this embodiment, when the clamping member 34 moves outward, it will drive the third baffle to move, thereby compressing the third spring.
[0083] When the first separating member 5 moves downward, the first separating member 5 will drive the collar 33 to move. The collar 33 will first contact the clamping member 34 and push the clamping member 34 to move outward. The clamping member 34 compresses the third spring. When the clamping port moves to the position of the clamping member 34, the third spring rebounds and pushes the clamping member 34 into the clamping port. At this time, the first separating member 5, the second separating member 6, and the third separating member 7 are just inserted into the corresponding first annular groove, second annular groove, and third annular groove.
[0084] When cleaning the fixed particles in the separation structure, it is necessary to separate the first separation member 5, the second separation member 6, and the third separation member 7 from the filter plate 2. However, due to the relatively large weight of the first separation member 5, the second separation member 6, and the third separation member 7 themselves, it is inconvenient to manually separate them.
[0085] To solve the above problems, this embodiment proposes an implementation manner. The solid-liquid separation device for water quality detection further includes: a moving device; the moving device is arranged in the middle inside the protective housing 8 and is used to vertically move the first separation member 5, the second separation member 6, and the third separation member 7.
[0086] In this embodiment, as Figure 2 and Figure 4 shown, the moving device includes: a fixed housing 19, two groups of telescopic rods 20, a threaded rod 22, a second electric push rod 21, a second motor 23, a moving member 24, two groups of fixing members 25, and a first elastic member 26.
[0087] Among them, the two groups of telescopic rods 20 are arranged on both sides above the fixed housing 19, and one end of the telescopic rod 20 is fixedly connected to the fixed housing 19, and the other end is fixedly connected to the protective housing 8.
[0088] In this embodiment, the two groups of telescopic rods 20 are each composed of a hollow cylinder and a solid cylinder sleeved together, which can limit the fixed housing 19 to only move vertically and cannot rotate.
[0089] The threaded rod 22 passes through the corresponding position of the fixed housing 19 and is slidably connected to the fixed housing 19.
[0090] In this embodiment, the fixed housing 19 can support the rotation of the threaded rod 22, and at the same time, when the threaded rod 22 moves vertically, it can also drive the fixed housing 19 to move.
[0091] The output end of the second electric push rod 21 is fixedly connected to the top end of the threaded rod 22; the output end of the second motor 23 is fixedly connected to the upper surface of the second electric push rod 21.
[0092] In this embodiment, the model of the second electric push rod 21 is selected according to actual needs as long as it meets the working conditions; the model of the second motor 23 is selected according to actual needs as long as it meets the working conditions;
[0093] The output end of the second electric push rod 21 can push the fixed housing 19 to move vertically downward through the threaded rod 22 and make the telescopic rod 20 expand and contract, while the output end of the second motor 23 can drive the threaded rod 22 to rotate through the second electric push rod 21. At this time, the fixed housing 19 will not rotate under the restriction of the two groups of telescopic rods 20.
[0094] The moving member 24 is composed of a transverse plate and two groups of wedge blocks. The two ends of the transverse plate are fixedly connected to the two groups of wedge blocks respectively; the transverse plate is in threaded connection with the threaded rod 22.
[0095] In this embodiment, when the threaded rod 22 rotates, the moving member 24 will move vertically.
[0096] One end of each fixing member 25 is in contact with the side of the wedge block away from the transverse plate; the contact surface between the fixing member 25 and the wedge block is an inclined surface.
[0097] In this embodiment, when the moving member 24 moves vertically downward, the fixing member 25 will move outward through the inclined contact surface.
[0098] The first elastic member 26 is composed of a first spring and a first baffle. The first spring is arranged between the first baffle and the fixed housing 19 and is sleeved on the outer surface of the fixing member 25; the inner wall of the first baffle is fixedly connected to the fixing member 25.
[0099] In this embodiment, when the fixing member 25 moves outward, it will drive the first baffle to move synchronously, thereby compressing the first elastic member 26.
[0100] When it is necessary to clean the inside of the separation structure, adjust the second electric push rod 21 so that the output end of the second electric push rod 21 pushes the fixed housing 19 and the internal structure downward through the threaded rod 22, and stop after pushing the fixed housing 19 to the lower part inside the third separation member 7. At this time, start the second motor 23, and the output end of the second motor 23 drives the threaded rod 22 to rotate through the second electric push rod 21. At this time, the fixed housing 19 will not rotate under the restriction of the two groups of telescopic rods 20; as the threaded rod 22 rotates, the moving member 24 will move vertically downward; the moving member 24 will make the fixing member 25 move outward through the inclined contact surface; the fixing member 25 drives the first baffle to move synchronously, thereby compressing the first elastic member 26; stop when the fixing member 25 abuts against the inside of the third separation member 7. At this time, reverse-adjust the second electric push rod 21 and pull the first separation member 5, the second separation member 6 and the third separation member 7 vertically upward through the entire moving device, so that the first separation member 5, the second separation member 6 and the third separation member 7 are separated from the filter plate 2, and the solid particles on the filter plate 2 are cleaned through the box door on the outer wall of the separation box 1.
[0101] After long-term use, the first separation member 5, the second separation member 6 and the third separation member 7 will be blocked, thus reducing the separation efficiency.
[0102] To solve the above problems, this embodiment proposes an implementation method. The solid-liquid separation device for water quality detection further includes: a dredging device; the dredging device is arranged on both sides inside the protective housing 8 and is used for dredging the first separation member 5, the second separation member 6 and the third separation member 7.
[0103] In this embodiment, as Figure 2 shown, the dredging device includes: a moving rod 11, a first electric push rod 12, two groups of connecting rods 13, two groups of moving plates 14, two groups of first dredging members 16, two groups of third dredging members 18, two groups of second dredging members 17, and two groups of limiting members 15.
[0104] Specifically, the output end of the first electric push rod 12 is fixedly connected to the upper end surface of the moving rod 11.
[0105] In this embodiment, the model of the first electric push rod 12 is selected according to actual needs as long as it meets the working conditions; the output end of the first electric push rod 12 can push the moving rod 11 to move vertically.
[0106] One end of each group of connecting rods 13 is rotatably connected to the moving rod 11; one end of each group of moving plates 14 is rotatably connected to the other end of the connecting rod 13.
[0107] In this embodiment, when the moving rod 11 moves vertically, it will cause the two groups of connecting rods 13 to move horizontally while rotating, and the connecting rods 13 will pull the two groups of moving plates 14 to move, so that the two groups of moving plates 14 move towards the middle or towards the outside at the same time.
[0108] Each group of first dredging members 16 is arranged on the side of the moving plate 14 away from the moving rod 11; on the side of the first dredging member 16 close to the moving plate 14, a plurality of first dredging columns corresponding to the first filter holes are provided, and the outer diameter of the first dredging column is slightly smaller than the inner diameter of the first filter hole
[0109] In this embodiment, the shape of the first dredging member 16 is a semi-hollow cylinder, and there is a gap between the two groups of first dredging members 16, which will not hinder the movement of the first separating member 5, the second separating member 6, and the third separating member 7.
[0110] Each group of third dredging members 18 is arranged on the side of the moving plate 14 close to the moving rod 11; on the side of the third dredging member 18 close to the moving plate 14, a plurality of third dredging columns corresponding to the third filter holes are provided, and the outer diameter of the third dredging column is slightly smaller than the inner diameter of the third filter hole.
[0111] In this embodiment, the shape of the third dredging member 18 is a semi-hollow cylinder, and its size is smaller than that of the first dredging member 16.
[0112] Each group of second dredging members 17 is arranged between the first dredging members 16 and the third dredging members 18; on the side of the second dredging member 17 close to the moving plate 14, a plurality of second dredging columns corresponding to the second filter holes are provided, and the outer diameter of the second dredging column is slightly smaller than the inner diameter of the second filter hole.
[0113] In this embodiment, the shape of the second dredging member 17 is a semi-hollow cylinder, and its size is smaller than that of the first dredging member 16 and larger than that of the third dredging member 18; when the moving plate 14 moves, it will drive the first dredging member 16, the second dredging member 17 and the third dredging member 18 to move horizontally.
[0114] Each limiting member 15 has a slideway on its surface, and three sliders are arranged in the slideway. The three sliders are fixedly connected to the first dredging member 16, the second dredging member 17 and the third dredging member 18 respectively.
[0115] In this embodiment, by the sliding between the slider and the slideway, it is restricted that the first dredging member 16, the second dredging member 17 and the third dredging member 18 can only move horizontally.
[0116] When dredging is required, the moving device is used to move the first separating member 5, the second separating member 6 and the third separating member 7 upward, and stop after being level with the first dredging member 16, the second dredging member 17 and the third dredging member 18. At this time, the first electric push rod 12 is adjusted so that the output end of the first electric push rod 12 pushes the moving rod 11 downward. The moving rod 11 will make the two connecting rods 13 move toward the middle while rotating. The connecting rods 13 pull the moving plate 14 to move. The moving plate 14 simultaneously drives the first dredging member 16, the second dredging member 17 and the third dredging member 18 to move horizontally, so that the first dredging column is inserted into the corresponding first filtering hole, the second dredging column is inserted into the corresponding second filtering hole, and the third dredging column is inserted into the corresponding third filtering hole to dredge the first separating member 5, the second separating member 6 and the third separating member 7.
[0117] After the dredging is completed, some solid particles will adhere to the first dredging member 16, the second dredging member 17 and the third dredging member 18, and still need to be manually cleaned.
[0118] To solve the above problems, this embodiment proposes an implementation method. The solid-liquid separation device for water quality detection further includes: a vibration device; the vibration device is arranged on both sides of the outer surface of the protective housing 8 and is used to impact the first dredging member 16.
[0119] In this embodiment, as Figure 2 and Figure 5 shown, the vibration device includes: a worm 27, a third motor 28, a worm wheel 29, a rotating member 30, an impact member 31 and a second elastic member 32.
[0120] Among them, the output end of the third motor 28 is fixedly connected to the bottom end of the worm 27; the worm wheel 29 is meshed with the worm 27.
[0121] In this embodiment, the model of the third motor 28 is selected according to actual needs as long as it meets the working conditions; the output end of the third motor 28 drives the worm 27 to rotate, and the worm 27 simultaneously drives the worm wheel 29 to rotate.
[0122] The rotating member 30 is composed of a disc and four groups of toggling rods. The four groups of toggling rods are evenly arranged on the edge of the disc, and the disc is coaxially arranged with the worm gear 29.
[0123] In one embodiment of the present invention, the worm gear 29 can drive the rotating member 30 to rotate.
[0124] A cylindrical pin is arranged on the surface of the impact member 31, and the cylindrical pin is in contact with a group of toggling rods; an impact ball is arranged at one end of the impact member 31.
[0125] In this embodiment, when the rotating member 30 rotates, it will push the cylindrical pin to move horizontally through the toggling rod, thereby driving the impact member 31 to move.
[0126] The second elastic member 32 is composed of a second spring and a second baffle. The second spring is arranged between the second baffle and the protective housing 8 and is sleeved on the outer surface of the impact member 31. The second baffle is fixedly connected to the impact member 31.
[0127] In this embodiment, when the impact member 31 moves in a direction away from the first dredging member 16, it will drive the second baffle to move, thereby compressing the second spring.
[0128] When oscillation is required, start the third motor 28. The output end of the third motor 28 drives the worm 27 to rotate; the worm 27 simultaneously drives the worm gear 29 to rotate slowly, and the worm gear 29 drives the rotating member 30 to rotate clockwise; when a group of toggling rods on the rotating member 30 push the cylindrical pin, it will push the impact member 31 to move in a direction away from the first dredging member 16 through the cylindrical pin; at the same time, the impact member 31 drives the second baffle to move, thereby compressing the second spring; and after this group of toggling rods are separated from the cylindrical pin, the second spring will rebound; so that the impact member 31 impacts on the first dredging member 16, generating vibration; making the solid particles adhering to the first dredging member 16, the second dredging member 17 and the third dredging member 18 fall onto the filter plate 2 for cleaning.
[0129] Working principle:
[0130] When the solid-liquid separation device for water quality detection is in use, first insert the first separation member 5, the second separation member 6 and the third separation member 7 into the first annular groove, the second annular groove and the third annular groove respectively, so that the clamping block 3 is inserted into the notch; during this process, the first separation member 5 will drive the collar 33 to move; the collar 33 will first contact the clamping member 34 and push the clamping member 34 to move outward, and the clamping member 34 compresses the third spring; when the clamping port moves to the position of the clamping member 34, the third spring rebounds and pushes the clamping member 34 to insert into the clamping port; and at this time, the first separation member 5, the second separation member 6 and the third separation member 7 are just inserted into the corresponding first annular groove, the second annular groove and the third annular groove.
[0131] Subsequently, pour the sewage to be separated into the interior of the third separation member 7 through the liquid inlet pipe 9; and start the first motor 4, the output end of the first motor 4 drives the filter plate 2 to rotate; the filter plate 2 drives the first separation member 5, the second separation member 6 and the third separation member 7 to rotate synchronously through multiple groups of clamping blocks 3; the sewage is caused to move outward by centrifugal force, while the solid particles will remain in the middle; at the same time, the first filter holes, the second filter holes and the third filter holes with different inner diameters are used for hierarchical filtration, so as to achieve solid-liquid separation, and the addition of centrifugal force can increase the separation speed.
[0132] When it is necessary to clean the interior of the separation structure, adjust the second electric push rod 21, so that the output end of the second electric push rod 21 pushes the fixed housing 19 and the internal structure downward through the threaded rod 22; stop after pushing the fixed housing 19 to the lower part inside the third separation member 7; at this time, start the second motor 23, and the output end of the second motor 23 drives the threaded rod 22 to rotate through the second electric push rod 21; and the fixed housing 19 at this time will not rotate under the restriction of the two telescopic rods 20; as the threaded rod 22 rotates, the moving member 24 will move vertically downward; the moving member 24 will make the fixing member 25 move outward through the inclined contact surface; the fixing member 25 drives the first baffle to move synchronously, so as to compress the first elastic member 26; stop after the fixing member 25 abuts against the inside of the third separation member 7; at this time, reversely adjust the second electric push rod 21, and pull the first separation member 5, the second separation member 6 and the third separation member 7 vertically upward through the whole moving device; so that the first separation member 5, the second separation member 6 and the third separation member 7 are separated from the filter plate 2, and the solid particles on the filter plate 2 are cleaned through the box door on the outer wall of the separation box 1.
[0133] When it is necessary to dredge, use the moving device to move the first separation member 5, the second separation member 6 and the third separation member 7 upward; stop after being level with the first dredging member 16, the second dredging member 17 and the third dredging member 18; at this time, adjust the first electric push rod 12, so that the output end of the first electric push rod 12 pushes the moving rod 11 downward; the moving rod 11 will make the two connecting rods 13 move toward the middle while rotating; the connecting rods 13 pull the moving plate 14 to move; the moving plate 14 drives the first dredging member 16, the second dredging member 17 and the third dredging member 18 to move horizontally at the same time; so that the first dredging column is inserted into the corresponding first filter hole, the second dredging column is inserted into the corresponding second filter hole, and the third dredging column is inserted into the corresponding third filter hole; dredge the first separation member 5, the second separation member 6 and the third separation member 7.
[0134] After the dredging is completed, the third motor 28 is started, and the output end of the third motor 28 drives the worm 27 to rotate; the worm 27 simultaneously drives the worm wheel 29 to rotate slowly, and the worm wheel 29 drives the rotating member 30 to rotate clockwise; when a group of toggle rods on the rotating member 30 push the cylindrical pin, the cylindrical pin will push the impact member 31 to move away from the first dredging member 16; at the same time, the impact member 31 drives the second baffle to move, thereby compressing the second spring; and after this group of toggle rods are separated from the cylindrical pin, the second spring will rebound; so that the impact member 31 impacts on the first dredging member 16, generating vibration; causing the solid particles adhering to the first dredging member 16, the second dredging member 17 and the third dredging member 18 to fall onto the filter plate 2 for cleaning, and completing the use of this device this time.
