Description

Technical Field

[0001] This application relates to the field of slurry treatment technology, and in particular to a slurry separation and detection tank. Background Technology

[0002] Mineral slurry is a liquid mixture formed in industrial production by adding water and other auxiliary agents to solid raw materials such as ores and clays to extract target elements. The solid components in mineral slurry often contain valuable minerals, which can be recovered through solid-liquid separation, improving resource utilization. Furthermore, with increasingly stringent environmental regulations and stricter industrial wastewater discharge standards, the solids in mineral slurry need to be separated to reduce environmental impact.

[0003] The related technology discloses a solid-liquid separation method in which slurry is transported into a tank, and the solid particles in the slurry settle in the liquid under the action of gravity. At the same time, a flocculant is added to accelerate the settling speed, thereby achieving solid-liquid separation. A clear water layer, a sediment layer, and a deposit layer are formed from top to bottom inside the tank. Slurry is continuously added to the tank, and water is discharged from the clear water layer and material is discharged from the deposit layer.

[0004] Regarding the aforementioned technologies, to ensure the clarity of the clear water layer meets effluent standards, manual sampling and testing are required at regular intervals to determine whether flocculant needs to be added to improve the clarity of the clear water layer and facilitate its subsequent use. If too little flocculant is used, the clear water will not be clear enough; if too much flocculant is used, the filtration and unloading of the sediment layer will become extremely difficult. This method cannot precisely control the amount of flocculant added, is labor-intensive, and complex to operate. Utility Model Content

[0005] To simplify operation and save manpower, this application provides a slurry separation and testing tank.

[0006] This application provides a slurry separation and testing tank, which adopts the following technical solution:

[0007] A slurry separation and testing tank includes a tank body, a discharge pipe, and a water outlet pipe. The discharge pipe is used to discharge the solids in the sediment layer inside the tank, and the water outlet pipe is used to discharge the liquid in the clear water layer inside the tank. The tank body is equipped with a testing component for detecting the clarity of the water. The upper end of the tank body is equipped with a flocculant pipe for introducing flocculant into the tank body. The upper end of the tank body is equipped with a mounting plate, and the lower end of the mounting plate is equipped with a frequency converter connected to the testing component. The frequency converter is used to control the amount of flocculant added according to the detection results of the testing component.

[0008] By adopting the above technical solution, the clarification level of the clear water layer can be detected in real time by the detection component, and the amount of flocculant added can be automatically controlled by the frequency converter, which improves the efficiency and quality of water treatment and reduces the complexity and labor intensity of manual operation.

[0009] Optionally, the detection assembly includes a light source emitter and a light source receiver. A support rod is mounted on the mounting plate, with the light source emitter connected to the support rod below the mounting plate and the light source receiver connected to the support rod below the light source emitter.

[0010] By adopting the above technical solution, the setting of the light source emitter and light source receiver enables the detection component to reflect the clarity of the water by measuring the transmission of light in the clear water layer, reducing the waste of manpower and simplifying the operation.

[0011] Optionally, the upper end of the light source receiver is provided with a cleaning brush for cleaning impurities that block the light, and the cleaning brush is rotatably connected to the light source receiver along the vertical axis.

[0012] By adopting the above technical solution, the cleaning brush can automatically clean up obstructions on the light source receiver, ensuring accurate light source reception and thus improving the accuracy of detection.

The ring is located below the water outlet pipe, and the upper end of the cylinder is located below the mounting plate. The light source emitter and the light source receiver are both located on the side of the cylinder away from the ring.

[0014] By adopting the above technical solution, the liquid level of the slurry in the tank is controlled by setting up the ring and cylinder. When the slurry reaches a certain height, the liquid part will overflow through the cylinder and flow onto the ring, and then flow out from the outlet pipe, while the solid particles will remain in the tank and continue to settle, ensuring that the slurry has enough residence time in the tank to facilitate solid-liquid separation.

[0015] Optionally, the tank is equipped with a ore-blocking ring. The ore slurry enters the tank after passing through the ore-blocking ring. Several connecting rods are evenly arranged around the circumference of the ore-blocking ring, and the end of the connecting rod away from the ore-blocking ring is fixedly connected to the inner wall of the cylinder.

[0016] By adopting the above technical solution, the slurry enters the tank after passing through the ore barrier, which avoids damage to the detection components and improves the service life of the detection components.

[0017] Optionally, a first collar and a second collar are slidably connected on the support rod in the vertical direction. Both the first collar and the second collar are threaded with locking bolts. The threaded end of the locking bolt abuts against the support rod. The light source emitter is fixedly connected to the first collar, and the light source receiver is fixedly connected to the second collar.

[0018] By adopting the above technical solution, the positions of the light source transmitter and the light source receiver can be easily adjusted to adapt to different environments and operational needs.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a slurry separation and testing tank.

[0033] Reference Figure 1 and Figure 2 A slurry separation and testing tank includes a tank body 1, a water outlet pipe 12, a material outlet pipe 11, and a testing component 2 for detecting the clarity of water. The tank body 1 is internally divided into a clear water layer, a sediment layer, and a settling layer from top to bottom, with separation achieved through natural sedimentation between the layers. The material outlet pipe 11 is connected to the bottom of the tank body 1 to discharge solid materials from the settling layer; the water outlet pipe 12 is located at the height of the clear water layer to draw out the clarified water. The testing component 2 is designed to detect the clarity of the clear water layer. A flocculant pipe 13 for adding flocculant is also provided at the upper end of the tank body 1, and a mounting plate 3 is installed thereon. Below the mounting plate 3 is a frequency converter 14 connected to the testing component 2. The frequency converter 14 is electrically connected to the testing component 2 and is responsible for automatically controlling the amount of flocculant added into the tank through the flocculant pipe 13 based on the signal fed back from the testing component 2. When the transparency of the clear water layer decreases, it indicates that there are more suspended solids in the water. The frequency converter 14 will increase the dosage of flocculant to promote the sedimentation of suspended solids, and vice versa, thereby achieving automatic control and optimizing the treatment effect.

[0034] Reference Figure 2 Specifically, the detection component 2 includes a light source emitter 21 and a light source receiver 22. A support rod 31 is mounted on the mounting plate 3. The light source emitter 21 is connected to the support rod 31 below the mounting plate 3, and the light source receiver 22 is connected to the support rod 31 below the light source emitter 21. The light source emitter 21 and the light source receiver 22 work together to detect the clarity of the water. When the water quality changes, the intensity of the light received by the light source receiver 22 also changes accordingly. This function allows us to monitor the clarity of the clear water layer in real time.

[0035] Reference Figure 2 and Figure 3 A cleaning brush 221 is provided at the upper end of the light source receiver 22. The cleaning brush 221 is driven by a miniature motor and can rotate around the axis of the light source receiver 22 to remove impurities attached to the surface of the receiver and prevent them from affecting the reception of the light signal. The use of the cleaning brush 221 ensures the accuracy and long-term effectiveness of the detection system.

[0036] Reference Figure 1 and 2A circular ring 15 is fixed to the inner wall of the tank 1. The upper surface of the ring 15 is horizontal, and a cylinder 16 with a vertically oriented axis is connected to one side of the ring 15. This configuration of the cylinder 16 and the ring 15 can effectively control the liquid level of the slurry in the tank 1. Specifically, when the slurry level rises to a certain height, the liquid overflows through the cylinder 16 and flows onto the ring 15, and then is discharged through the outlet pipe 12, while the solid particles continue to settle inside the tank 1.

[0037] Reference Figure 1 and 2 Inside the tank 1, a retaining ring 17 is installed, through which the slurry must pass before entering the tank 1. This is to prevent the slurry from directly impacting the detection component 2, thus preventing damage and extending its service life. The retaining ring 17 also increases the turbulence of the slurry within the tank, improving the contact between the slurry and the flocculant, and promoting the collision and separation of solid particles in the slurry. Several connecting rods 171 are evenly connected around the retaining ring 17, with the other ends of these rods fixed to the inner wall of the cylinder 16, enhancing the structural stability.

[0038] Reference Figure 1 and 2 The outer side of the cylinder 16 is provided with a vertically sliding lifting cylinder 161, the inner wall of which is in contact with the outer wall of the cylinder 16. The height of the lifting cylinder 161 can be adjusted according to the volume of slurry added into the tank 1, which increases the flexibility and applicability of the equipment.

[0039] Reference Figure 2 and Figure 3 Three identical collars are slidably connected to the support rod 31, arranged vertically from top to bottom as the first collar 32, the third collar 34, and the second collar 33. The light source emitter 21 is fixedly connected to the first collar 32, the light source receiver 22 is fixedly connected to the second collar 33, and the lifting cylinder 161 is fixedly connected to the third collar 34. Each of these three collars is threaded with a locking bolt 35, the threaded end of which abuts against the support rod 31. All three collars can be fixed to any position on the support rod 31 using the locking bolts 35, thus allowing for flexible adjustment of the light source emitter 21, the light source receiver 22, and the lifting cylinder 161. This design allows for flexible adjustment of the position of the detection component 2 to accommodate different heights of clear water layers or for maintenance operations, improving the flexibility and stability of the equipment.

[0040] The implementation principle of a slurry separation and testing tank in this application embodiment is as follows: The light source emitter 21 emits light, which passes through the clear water layer. If the clear water layer is relatively clear, the light attenuation is reduced, and the light signal intensity received by the light source receiver 22 is high. If the clear water layer becomes turbid, suspended particles will scatter or absorb the light, causing the light signal received by the light source receiver 22 to weaken. The frequency converter 14 automatically adjusts the amount of flocculant added by continuously detecting changes in the intensity of the received light signal to ensure the clarity of the clear water layer, thereby achieving automated operation of the equipment and reducing the complexity and labor intensity of manual operation.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
