Description

Technical Field

[0001] This utility model relates to the field of sand content detection technology, and in particular to an improved sand content detection device. Background Technology

[0002] Sediment testing generally refers to the observation and measurement of the form and evolution process of sediment movement with water in watersheds and water bodies. It usually measures and calculates the sediment content and sediment transport rate of rivers. The steps of sediment content detection generally include sampling and sediment testing. Hydrological staff operate hydrological cableways and control bottle samplers to sample and analyze river water. After steps such as volumetric sampling, sedimentation, filtration, drying, and weighing, the weight of dry sand in a certain volume of turbid water is obtained. Finally, the sediment content and sediment transport rate of each part can be calculated. Among them, sedimentation, filtration, and drying require different equipment. This measurement method is obviously time-consuming and inefficient. Therefore, this utility model designs a new type of high-efficiency sediment content detection device. Utility Model Content

Detailed Implementation

[0005] Example 1: like Figures 1 to 3 As shown, an improved sand content detection device includes a cylindrical body 1 rotatably mounted on a frame 12. The cylindrical body 1 is connected to a transmission mechanism, which is mounted on the frame 12. An electric heating wire 3 is installed outside the cylindrical body 1. A filter screen cylinder 2 is coaxially installed inside the cylindrical body 1. The filter screen cylinder 2 divides the inner cavity of the cylindrical body 1 into a drainage chamber and a sand discharge chamber. A sand discharge pipe 11 is provided at the bottom of the sand discharge chamber, and a ball valve is installed on the sand discharge pipe 11. To insulate against heat and prevent burns to operators, such as Figure 3 As shown, a protective shell 4 is installed outside the cylinder 1, and heat insulation filler 5 is provided inside the protective shell 4. like Figure 2 and Figure 3As shown, a load-bearing ring 6 is horizontally mounted on the frame 12, and the cylinder 1 is disposed inside the load-bearing ring 6. Several ball bearing assemblies are evenly distributed on the load-bearing ring 6 along the circumferential direction. An mounting ring is installed outside the protective shell 4, and the mounting ring is in rolling connection with the ball bearing assemblies. The ball bearing assembly includes a vertically arranged compression spring 8, and a ball bearing 7 is disposed on the top of the compression spring 8. Several blind holes are evenly distributed on the load-bearing ring 6, and the compression spring 8 is installed in the blind holes. The ball bearing 7 is located at the opening of the blind holes. A raceway 9 matching the ball bearing 7 is provided at the bottom of the mounting ring. like Figure 2 As shown, the transmission mechanism further includes a gear shaft 13 and a ring gear 14. The gear shaft 13 meshes with the ring gear 14. The gear shaft 13 is rotatably connected to the frame 12 and is connected to the electric motor for transmission. In practice, the sample liquid to be tested is poured into the annular sand discharge chamber. Through the filtration effect of the filter screen cylinder 2, the mud and sand are left in the sand discharge chamber and adhere to the filter screen cylinder 2. Water enters the drainage chamber and is discharged through the water outlet pipe 10. Then, the heating wire 3 is started to heat the chamber and evaporate the small amount of water remaining in the sand discharge chamber. Then, the motor is started to make the cylinder 1 rotate at high speed, thereby throwing out all the mud and sand adhering to the filter screen cylinder 2. Finally, the mud and sand are discharged from the sand discharge pipe 11. Example 2: Example 2 further optimizes the structure based on Example 1, such as... Figures 1 to 3 As shown, the sand discharge pipe 11 is tangent to the sand discharge chamber. The rotation direction of the cylinder 1 is consistent with the sand discharge direction of the sand discharge pipe 11. When the cylinder 1 stops rotating, the dry mud and sand will concentrate and enter the sand discharge pipe 11 due to its own gravity and centrifugal inertia. The inner wall of the cylinder 1 is a cone shape with a larger upper part and a smaller lower part, so that the mud and sand will move downward when the cylinder 1 rotates at high speed. At the same time, the inner wall of the cylinder 1 can be polished to prevent mud and sand from adhering. A cloth hopper 15 is provided at the top of the filter cylinder 2. The function of the cloth hopper 15 is to allow the liquid to be tested to enter the sand discharge chamber smoothly. The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
