Description

Technical Field

[0001] This utility model relates to the technical field of turbidity detection equipment, and in particular to an automatic turbidity detection device for a thickener. Background Technology

[0002] Currently, in the solid-liquid separation process of thickeners, flocculants are usually added and pH values ​​are controlled to control the solid content of the supernatant. When detecting the turbidity of the liquid inside the thickener, the liquid is usually manually suspended in a bucket and judged by sensory perception, which leads to inaccurate liquid turbidity judgment. Alternatively, a probe equipped with a turbidity sensor can be thrown with a hand-held sling to be placed into the liquid inside the thickener for detection, and accurate detection results can be obtained through the turbidity sensor.

[0003] In existing thickener turbidity detection methods, relying on sensory judgment during actual operation reduces detection accuracy. If the probe is thrown using a handheld sling, some liquid adheres to its surface upon retrieval. To prevent corrosion from prolonged contact with internal thickener liquid, manual rinsing of the probe and sling is necessary, significantly reducing the convenience of probe maintenance. Therefore, this application proposes an automatic thickener turbidity detection device that ensures structural accuracy while facilitating probe cleaning and maintenance. Utility Model Content

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example

[0034] like Figure 1As shown, the present invention proposes an automatic turbidity detection device for a thickener, comprising a base 1, a support frame 2 fixedly mounted on the top of the base 1, a suspension 7 fixedly mounted on the support frame 2, an annular pipe 73 fixedly mounted on the bottom of the suspension 7 away from the support frame 2, and several inwardly inclined nozzles 731 fixedly mounted on the bottom of the annular pipe 73. Water is concentratedly sprayed from the multiple nozzles 731 onto the area near the middle of the annular pipe 73 to facilitate rinsing of the recovered probe 8. A winding drum 5 is rotatably mounted on the support frame 2, and a sling 6 is wound on the winding drum 5. One end of the sling 6 passes through the annular pipe 73 and extends below it. A probe 8 is fixedly mounted on the bottom end of the sling 6. A turbidity sensor (model: Endress+Hauser Turbimax CUS52D) is installed on the probe 8. The turbidity sensor detects the turbidity of the liquid inside the thickener and transmits the detection results to the back-end terminal wirelessly, ensuring the accuracy of the detection results.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, to facilitate control of the diving depth of the probe 8, a control cabinet 4 is fixedly installed on the support frame 2. A motor is installed inside the control cabinet 4, and the output end of the motor is fixedly connected to one end of the rotating shaft 54 ​​installed on the winding drum 5. A power supply cabinet 3 is fixedly installed on the support frame 2, and the power supply cabinet 3 is electrically connected to the control cabinet 4 via cables, supplying power to the control cabinet 4 to ensure that the motor can drive the winding drum 5 to rotate, facilitating the unwinding and rewinding of the sling 6 wound on the winding drum 5. The control cabinet 4 contains a control circuit board that can control the number of rotations of the motor output end (this is existing technology and will not be elaborated here). During the unwinding of the sling 6 and the downward movement of the probe 8, the downward movement distance of the probe 8 can be controlled, facilitating control of the diving depth of the probe 8. This allows the probe 8 to detect liquids at different depths inside the thickener, effectively improving its applicability.

[0036] Furthermore, such as Figure 5 and Figure 6 As shown, in order to ensure that the slings 6 wound on the winding drum 5 are evenly distributed and to prevent them from winding haphazardly, two positioning plates 51 are fixedly installed at both ends of the metal drum 52 and assembled into the winding drum 5. Several annular grooves 521 are chiseled on the outer wall of the metal drum 52. The part of the slings 6 wound on the metal drum 52 is embedded in the corresponding annular grooves 521. The annular grooves 521 limit the horizontal direction of the single-turn wound slings 6, effectively preventing them from winding haphazardly.

[0037] Secondly, such as Figure 6As shown, in order to improve the stability when rotating around the drum 5, a rotating shaft 54 ​​is fixedly installed on both positioning plates 51. The end of the rotating shaft 54 ​​away from the control cabinet 4 is rotatably installed on the support frame 2, and the end of the rotating shaft 54 ​​close to the control cabinet 4 is movably sleeved with a limit seat 53. The limit seat 53 is fixedly installed on the support frame 2 by bolts. The limit seat 53 can not only support the rotating shaft 54, but also bear the force at the connection between the rotating shaft 54 ​​and the motor output end, avoiding increasing the load on the motor output end and effectively improving the stability when rotating around the drum 5.

[0038] like Figure 2 and Figure 3 As shown, in order to improve the stability of the sling 6 during retraction and extension, a support plate 71 is fixedly installed at the top of the suspension 7 on the side away from the support frame 2. A first guide assembly 72 is fixedly installed at the top of the support plate 71. Two first guide wheels 721 are rotatably installed on the first guide assembly 72. A second guide assembly 75 is fixedly installed at the top of the suspension 7 on the side closer to the support frame 2. Two second guide wheels 751 are rotatably installed on the second guide assembly 75. One end of the sling 6 passes through the gap between the two first guide wheels 721 and the two second guide wheels 751, and overlaps the first guide wheel 721 and the second guide wheel 751 located below. The guide wheels arranged in pairs limit the sling 6 in the horizontal and vertical directions. During the retraction and extension of the sling 6, it can prevent jamming and ensure that it is retracted and extended along the fixed track, effectively improving the stability of the sling 6 during retraction and extension.

[0039] like Figures 1-5 As shown, to ensure that the water sprayed from the nozzle 731 has sufficient impact force and improves the cleaning effect on the probe 8, several suspension sleeves 77 are fixedly installed at the bottom of the suspension 7. A water guide pipe 76 is fixedly installed on the several suspension sleeves 77. One end of the water guide pipe 76 is fixedly connected to the annular pipe 73 and communicates with its interior. A high-pressure water pump 10 is fixedly installed on the top of the base 1. The high-pressure water pump 10 is electrically connected to the control cabinet 4 through a cable. The control cabinet 4 can control the solenoid valve installed on the high-pressure water pump 10 and its internal components. The motor (which is existing technology and will not be described in detail here) is installed to facilitate the opening and closing of the high-pressure water pump 10; a hose 9 is fixedly installed at the inlet port of the high-pressure water pump 10, and the end of the hose 9 away from the high-pressure water pump 10 is fixedly connected to the water guide pipe 76. The inlet port of the high-pressure water pump 10 is fixedly connected to the external water supply pipe to ensure that the high-pressure water pump 10 can pressurize the external water and deliver it into the annular pipe 73, ensuring that the water sprayed from the nozzle 731 has sufficient impact force to effectively improve the cleaning effect on the probe 8.

[0040] Secondly, such as Figure 1 and Figure 2As shown, a connecting frame 74 is fixedly installed at one end of the suspension 7 near the support frame 2. The connecting frame 74 is fixedly assembled on the support frame 2 by bolts to ensure that the suspension 7 can be firmly connected to the support frame 2. The suspension 7 can be disassembled by removing the bolts installed on the connecting frame 74, which facilitates the maintenance of the guide wheel assembly installed on the suspension 7.

[0041] like Figure 1 and Figure 5 As shown, a shield 11 is fixedly installed on the support frame 2, and the high-pressure water pump 10 is installed below the shield 11. In rainy weather, the shield 11 can protect the high-pressure water pump 10 from rain, preventing rainwater from contacting the motor inside the high-pressure water pump 10 and improving the protection effect of the high-pressure water pump 10.

[0042] In this embodiment, the motor installed inside the control cabinet 4 first drives the winding drum 5 to rotate, thereby winding and unwinding the sling 6. After the sling 6 enters the unwinding stage, the probe 8 can be lowered, making it easy to place the probe 8 into the thickener through the circular opening at the top. When the probe 8 is immersed in the liquid inside the thickener, the turbidity of the liquid inside the thickener can be detected by the turbidity sensor installed on the probe 8, which improves the accuracy of the detection results compared to human sensory judgment. After the detection is completed, the winding drum 5 rotates in the opposite direction and the sling 6 is wound up. During this process, the sling 6 moves the probe 8 upward. When the probe 8 moves upward... After moving to a position below and close to the annular tube 73, water is supplied to the inside of the annular tube 73 by the high-pressure water pump 10, and high-pressure water jets are sprayed outward through multiple nozzles 731. Since multiple nozzles 731 are all set towards the inside of the annular tube 73, multiple high-pressure water jets can be concentrated and sprayed onto the probe 8, which can clean the liquid carried out from the inside of the thickener from the surface of the probe 8, preventing corrosion caused by long-term adhesion of the liquid inside the thickener to the surface of the probe 8. The automatic cleaning method completes the cleaning operation during the probe 8 recovery process, eliminating the need for manual cleaning, improving the efficiency of the cleaning operation, and effectively improving the convenience of probe 8 maintenance.

[0043] The above specific embodiments are merely several optional embodiments of this utility model.
