Detailed Description
The following combines the drawings of the utility model to further elaborate the technical scheme and technical effect of the utility model.
Referring to fig. 1 and 2, in one embodiment, an apparatus 10 for detecting a solid-liquid boundary position is provided on a solid-liquid contact container 20, and includes: the weight 100, the traction rope 200 and the lifting measuring device 300, wherein the weight 100 is disposed in the container 20, and the density of the weight 100 is greater than the density of the liquid phase. One end of the traction rope 200 is connected to the weight 100, and the other end thereof passes around the upper end of the container 20. The lifting and lowering measuring device 300 is connected to an end of the traction rope 200 away from the weight 100, and the traction rope 200 can be displaced relative to the lifting and lowering measuring device 300 to vertically lift and lower the weight 100.
For example, the lifting measuring assembly 300 includes a winch 310 fixedly disposed at the lower end of the container 20, one end of the hauling cable 200 away from the weight 100 is wound on the winch 310, the winch 310 rotates, and the hauling cable 200 can be wound on the winch 310 or released from the winch 310, so as to lift the weight 100 in the vertical direction.
When the weight is mounted, the weight 100 is placed in the solid-liquid contact container 20, and the traction rope 200 is connected to the elevation measuring unit 300 while bypassing the upper end of the container 20. During measurement, the weight 100 descends along the vertical direction to reach the solid-liquid boundary position, and stops under the resistance of a solid phase, so that the solid-liquid boundary position in the container 20 can be visually observed according to the displacement of the traction rope 200 relative to the lifting measurement assembly 300. The device has simple structure, accurate measurement and difficult damage.
Further, for the solid-liquid boundary position in the container 20 of directly perceived reading, the lift measuring assembly 300 still includes scale 320 and pointer 330, scale 320 sets up on the container 10 outer wall, pointer 330 fixed set up in on the haulage rope 200, the orthographic projection of pointer 330 can with scale 320 coincide. For example, when the vessel 20 is filled with a solid-phase substance, the capstan 310 is rotated to wind the drag rope 200 around the capstan 310 and to position the weight 100 at the highest point, and at this time, the orthographic projection of the pointer 330 is positioned at the lower end of the scale 320, that is, at the highest solid-liquid boundary position. After the solid phase loading is completed, the weight 100 is allowed to fall naturally, and the pointer 330 moves upward. When the weight 100 contacts the solid-liquid boundary position, the weight stops falling, and at this time, the displacement of the traction rope 200 relative to the capstan 310, that is, the relative displacement of the pointer 330, is the current solid-liquid boundary position. As the solid-liquid reaction proceeds, the solid phase is consumed, the solid-liquid boundary position moves downward, the weight moves downward, and the pointer 330 moves upward to obtain the solid-liquid boundary position in the reaction process in real time.
Preferably, the winch 310 is provided with a locking member 311, and in the measuring state, the locking member 311 is opened, and the winch 310 rotates to enable the weight 100 to fall normally. When solid phase is fed, the weight 100 is lifted to the highest point, and the winch 310 is locked by the locking member 311, so as to prevent the weight 100 from being pressed to the bottom of the solid phase during the solid phase feeding process.
In one embodiment, the apparatus 10 for detecting a solid-liquid separation position further comprises a steering assembly 400, wherein the steering assembly 400 is disposed at the upper end of the container 20 and comprises at least one steering pulley 410, and the traction rope 200 is wound around the steering pulley 410 and connected to the lifting measuring assembly 300. Further, the steering assembly 400 further comprises a pulley mounting seat 420, the pulley mounting seat 420 can be fixed on the container 20, and the steering pulley 410 is mounted in the pulley mounting seat 420. The traction rope 200 bypasses the steering assembly 400, on one hand, the traction rope 200 is prevented from contacting the wall of the container 20, the wear of the traction rope 200 is reduced, the service life of the traction rope 200 is prolonged, and on the other hand, the weight 100 can be installed as close as possible to the middle of the container 20 by using the steering assembly 400, so that the measurement is more accurate.
In another preferred embodiment, the area of the lower surface of the weight 100 is not less than 50cm2So that the weight 100 can smoothly contact with the upper surface of the solid phase to reduce the local protrusion or recess of the solid phase surfaceThe measurement error caused by the trap improves the accuracy of the measurement of the solid-liquid boundary position.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
