Description

Technical Field

[0001] The utility model relates to the technical field of turbidity detectors, in particular to an online turbidity detector. Background Technique

[0002] A turbidity detector is a precision instrument used to monitor the turbidity of liquids in real time. By emitting light of a specific wavelength through the liquid to be detected and then receiving and analyzing the intensity of the scattered light, the turbidity value of the liquid can be accurately measured.

[0003] Turbidity detectors are widely used in many fields. In the water treatment industry, turbidity detectors are used in water treatment plants to monitor the turbidity of raw water and treated water to ensure that the water supply quality meets the standards. Sewage treatment plants rely on them to evaluate the treatment effect and determine whether further treatment steps are required. They play an important role in ensuring water quality safety, optimizing production processes, protecting the environment, and promoting scientific research.

[0004] The existing turbidity detector consists of a light source emitter, a receiving and processing component, and a container. The light source emitter irradiates the water sample inside the container, and the receiving and processing component then detects the brightness of the received light. By comparing the obtained value with the original value, the turbidity can be obtained. However, due to the uncertainty of the water sample, it may contain particulate matter or bubbles inside, resulting in uncertainty in the detected value. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 、 Figure 2 and Figure 3 ,the utility model provides an embodiment: an online turbidity detector, which includes a housing 1. A feed hopper 3 is communicated with the top wall of the housing 1. A conical block 4 is fixedly connected to the middle of the inner wall of the feed hopper 3. The bottom end of the feed hopper 3 is communicated with a glass detection bottle 5. Detection surfaces 6 are provided on both the left and right sides of the glass detection bottle 5. A propeller 7 is fixedly installed in the middle and lower part of the inner wall of the glass detection bottle 5. A light source emitter 8 is fixedly connected to the middle of the left side of the inner wall of the housing 1. A light source detector 9 is fixedly connected to the middle of the right side of the inner wall of the housing 1. A discharge pipe 10 is communicated with the bottom end of the glass detection bottle 5. A valve 11 is fixedly installed in the middle of the discharge pipe 10. A cleaning mechanism 2 is arranged on the front side of the inner wall of the housing 1;

[0032] Specifically, when the water sample to be measured enters the device through the feed hopper 3, the conical block 4 can effectively reduce the bubbles in the water sample entering the device. Because the water flow flows on the surface of the conical block 4, the bubbles in the water flow will be pushed to the edge and discharged, thus ensuring the accuracy of subsequent measurements. The preliminarily treated water sample enters the glass detection bottle 5. The water sample forms a transparent plane by the detection surfaces 6 on both sides, allowing the light source to pass through for turbidity detection. At the same time, the propeller 7 rotates inside the glass detection bottle 5, which can further stir the water sample to make the suspended substances in it more evenly distributed, thereby improving the detection accuracy. The light source emitter 8 is located in the middle of the left side of the housing 1. It emits a stable light beam. These light beams pass through the water sample and the detection surface 6 and finally reach the light source detector 9 located in the middle of the right side of the housing 1. Since the suspended substances in the water sample will scatter and absorb light, the light intensity received by the light source detector 9 will change. This change is directly related to the turbidity of the water sample. By measuring this change, the turbidity value of the water sample can be obtained. After the detection is completed, the water sample can be discharged from the discharge pipe 10 by opening the valve 11. By using the propeller 7 to stir the water sample during the detection process, the suspended substances are evenly distributed, the detection accuracy is improved, and efficient and accurate turbidity detection is realized.

[0033] Referring to Figure 1 and Figure 4, the cleaning mechanism 2 includes a carrier plate 201. Two guide rails 202 are fixedly connected to the front side of the inner wall of the carrier plate 201. Guide wheels 203 are slidably connected to the outer walls of the two guide rails 202. Electric motors 204 are fixedly connected to the rear ends of the two guide wheels 203. Rotating brushes 205 are fixedly connected to the rear ends of the two electric motors 204. Two rotating shafts 206 are fixedly connected to the inner bottom wall of the carrier plate 201. Telescopic rods 207 are rotatably connected to the top walls of the two rotating shafts 206. Connecting plates 208 are fixedly connected to the top ends of the two telescopic rods 207. The front sides of the top ends of the two connecting plates 208 are fixedly connected to the bottom ends of the two electric motors 204. The rear sides of the top ends of the two connecting plates 208 are rotatably connected to the outer walls of the two rotating brushes 205;

[0034] Specifically, the carrier plate 201 serves as the support foundation for the entire cleaning mechanism 2 and is fixedly connected to two guide rails 202. These two guide rails 202 provide sliding tracks for the guide wheels 203, enabling the guide wheels 203 to slide smoothly along them. When it is necessary to clean the detection surface 6, the two electric motors 204 start to work, driving the guide wheels 203 to move on the guide rails 202. Since the guide wheels 203 are fixedly connected to the electric motors 204, the movement of the electric motors 204 will drive the guide wheels 203 and the entire structure connected to them to move along the guide rails 202. At the same time, the electric motors 204 also drive the rotation of the rotating brushes 205. Driven by the electric motors 204, the rotating brushes 205 start to clean the detection surface 6. The rotation of the rotating brushes 205 can effectively remove the dust adsorbed on the detection surface 6 and ensure the cleanliness of the detection surface 6. Since the rotating brushes 205 are rotatably connected to the connecting plates 208, the rotating brushes 205 can adapt to the curvature change of the detection surface 6 while rotating, ensuring the uniformity and thoroughness of the cleaning. To achieve the lifting of the rotating brushes 205, the two rotating shafts 206 on the inner bottom wall of the carrier plate 201 can enable the telescopic rods 207 to rotate within a certain range. By controlling the telescopic length of the telescopic rods 207, the height of the connecting plates 208 and the rotating brushes 205 can be adjusted to adapt to the overall cleaning of the detection surface 6, realizing the effective cleaning of the detection surface 6.

[0035] Refer to Figure 1 and Figure 2 , a control console 12 is fixedly connected to the middle and lower part of the front side of the housing 1. A plurality of control buttons 13 are fixedly installed on the top wall of the control console 12; a timer 14 is fixedly installed on the middle and upper part of the front side of the housing 1. The timer 14 is electrically connected to the control console 12; anti-collision gaskets 15 are fixedly connected to the four corners on the left side and the four corners on the right side of the housing 1. A plurality of anti-collision gaskets 15 are all made of rubber material;

[0036] Specifically, the console 12 is the main operation interface of the turbidity detector. Instructions can be input, parameters can be set, and operations such as starting or stopping the detection can be performed through various control buttons 13 on the console 12. The timer 14 is used to record the time of the detection process. In turbidity detection, a specific detection time needs to be controlled to obtain accurate results. The anti-collision gasket 15 is used to reduce the damage to the instrument when it is collided or impacted, thereby protecting the internal components of the detector from damage.

[0037] Referring to Figure 2 , two hinges 16 are fixedly connected to the rear side of the housing 1. The left ends of the front sides of the two hinges 16 are fixedly connected with a maintenance door panel 17. The left end of the rear side of the maintenance door panel 17 is fixedly connected with two locking clasps 18; the middle of the top wall of the housing 1 is communicated with a sealing nozzle 19. The outer wall of the sealing nozzle 19 is threadedly connected with a sealing cap 20. The middle of the top wall of the sealing cap 20 is fixedly connected with a handle 21; the four corners of the bottom wall of the housing 1 are fixedly connected with columns 22. The bottom ends of the multiple columns 22 are fixedly connected with anti-slip pads 23;

[0038] Specifically, the hinge 16 is used to connect the housing 1 and the maintenance door panel 17, enabling the maintenance door panel 17 to be opened and closed smoothly, facilitating users to perform maintenance, repair, or cleaning on the inside of the turbidity detector. The locking clasp 18 ensures that the maintenance door panel 17 can be firmly locked on the housing 1 when it is closed, preventing it from accidentally opening and ensuring the safe operation of the device. The sealing nozzle 19 is used as the water inlet of the turbidity detector in cooperation with the sealing cap 20. When it is not necessary to connect a water pipe or other devices, the sealing cap 20 can be covered to prevent dust, impurities, etc. from entering the inside of the turbidity detector, maintaining the cleanliness and accuracy of the device. At the same time, the handle 21 facilitates users to operate the sealing cap 20. The columns 22 ensure that the device can be stably placed on a flat surface, avoiding tilting or shaking and ensuring the accuracy of the measurement. The anti-slip pads 23 at the bottom increase the friction between the turbidity detector and the placement surface, preventing the device from sliding or shifting during use.

[0039] Working principle: When the water sample to be measured enters the interior of the device through the feed hopper 3, the conical block 4 can effectively reduce the bubbles in the water sample entering the device. Since the water flow flows on the surface of the conical block 4, the bubbles in the water flow will be pushed to the edge and discharged, thus ensuring the accuracy of subsequent measurements. The preliminarily treated water sample enters the glass detection bottle 5. The water sample forms a transparent plane by the detection surfaces 6 on both sides, allowing the light source to pass through for turbidity detection. At the same time, the propeller 7 rotates inside the glass detection bottle 5, which can further stir the water sample to make the suspended substances in it more evenly distributed, thereby improving the detection accuracy. The light source emitter 8 is located in the middle of the left side of the housing 1. It emits a stable light beam. These light beams pass through the water sample and the detection surface 6 and finally reach the light source detector 9 located in the middle of the right side of the housing 1. Since the suspended substances in the water sample will scatter and absorb light, the intensity of the light received by the light source detector 9 will change. This change is directly related to the turbidity of the water sample. By measuring this change, the turbidity value of the water sample can be obtained. After the detection is completed, the water sample can be discharged from the discharge pipe 10 by opening the valve 11. By using the propeller 7 to stir the water sample during the detection process, the suspended substances are evenly distributed, the detection accuracy is improved, and efficient and accurate turbidity detection is realized.

[0040] Moreover, the carrier plate 201 serves as the support foundation of the entire cleaning mechanism 2 and is fixedly connected to two guide rails 202. These two guide rails 202 provide a sliding track for the guide wheels 203, enabling the guide wheels 203 to slide smoothly along them. When it is necessary to clean the detection surface 6, the two motors 204 start to work, driving the guide wheels 203 to move on the guide rails 202. Since the guide wheels 203 are fixedly connected to the motors 204, the movement of the motors 204 will drive the guide wheels 203 and the entire structure connected to them to move along the guide rails 202. At the same time, the motors 204 also drive the rotation of the rotating brush 205. Driven by the motors 204, the rotating brush 205 starts to clean the detection surface 6. The rotation of the rotating brush 205 can effectively remove the dust adsorbed on the detection surface 6 and ensure the cleanliness of the detection surface 6. Since the rotating brush 205 is rotatably connected to the connecting plate 208, the rotating brush 205 can adapt to the curvature change of the detection surface 6 while rotating, ensuring the uniformity and thoroughness of the cleaning. In order to realize the lifting of the rotating brush 205, the two rotating shafts 206 on the inner bottom wall of the carrier plate 201 can make the telescopic rod 207 rotate within a certain range. By controlling the telescopic length of the telescopic rod 207, the height of the connecting plate 208 and the rotating brush 205 can be adjusted to adapt to the overall cleaning of the detection surface 6, realizing the effective cleaning of the detection surface 6.
