Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of liquid level measurement, in particular to a method and a device for measuring an interface liquid level in a resin production process. Background Art
[0002] The resin interface level mainly refers to the interface position between the resin and other media (such as water, air, etc.) in the resin storage container or processing device. In the resin production process, this interface position is crucial for the storage, separation, and regeneration of the resin because it directly affects the resin utilization efficiency and process control. The resin interface level will change with the consumption, replenishment or treatment process of the resin. The measurement of the resin interface level is very important in the resin production process. The resin interface level is one of the important parameters for process control. It directly affects the separation effect, regeneration efficiency and stability of the subsequent treatment process of the resin. Accurately controlling the resin interface level can prevent safety accidents such as resin overflow or drying up, ensuring the smooth progress of the production process. At the same time, reasonable control of the resin interface level can improve the utilization rate of the resin, reduce waste and reduce production costs. During the resin production process, because the density of resin is greater than that of water, when the resin is stored, the water is located in the upper layer and the resin is located in the lower layer (such as Figure 1 As shown in the figure, it is difficult to eliminate the influence of water when measuring the resin interface liquid level, and it is difficult to complete the accurate measurement of the resin interface liquid level through the water layer; therefore, a method and device for measuring the interface liquid level in the resin production process are proposed.

[0012] The application also provides a use method of the interface liquid level measuring device in the resin production process, which comprises the following steps: S1, obtaining the distance s of the connecting rope moving when the pointer rotates one circle by pre-test, recording the height h of the positioning column, and releasing the float from the bottom of the tank; S2, the float starts to float in the resin, is affected by the resin viscosity, and slowly floats up, pulls the connecting rope during the floating process, drives the guide pulley, the winding roller and the rotating rod, and drives the driving gear, the driven gear, the mounting plate and the sleeve rod; S3, when the float floats into the water at the resin interface, the float suddenly speeds up due to the resin viscosity, the sleeve rod greatly increases the rotating speed, the sleeve slides outward on the sleeve rod under the centrifugal force, drives the clamping tooth to move and clamps the tooth ring, and the winding roller stops rotating, and the float stays at the resin interface; S4, from the start of the float floating to the float staying at the resin interface, the interface liquid level of the resin is the distance of the float moving plus the height of the positioning column, the number of circles of the pointer corresponds to the distance of the float floating, the pointer is recorded once by the light barrier switch when the pointer rotates one circle, the number of circles of the pointer is m by combining the scale disc, and the interface liquid level of the resin is m*s+h.
[0013] As a further preferred of the technical solution: in S3, during the sliding of the sleeve, the check teeth slide on the check groove, the smooth inclined surfaces press against each other, the spring two repeatedly stretch and contract, when the catch teeth catch the tooth ring, the vertical surface of the check groove blocks the vertical surface of the check teeth, preventing the sleeve from moving back, and the catch teeth and the tooth ring remain in the clamped state.
[0014] Compared with the prior art, the beneficial effects of the present application are: 1、The present application changes the movement state of the catch teeth by using the speed difference of the float in the resin and water, and locks the float at the resin interface, which can effectively position the resin interface.
[0015] 2、When the float is floating in the resin, the floating speed is slow due to the influence of the resin viscosity, and the connecting rope drives the pointer and the catch teeth to rotate during the floating process. When the float floats to the resin interface and enters the water, the floating speed suddenly increases due to the release of the resin viscosity, the rotation speed of the sleeve increases greatly, the catch teeth move to catch the tooth ring, and the float stays at the resin interface. The number of turns of the pointer corresponds to the floating distance of the float, so the resin interface liquid level is obtained.
[0016] 3、When the present application works, the check teeth slide on the check groove during the sliding of the sleeve, the smooth inclined surfaces press against each other, the spring two repeatedly stretch and contract, when the catch teeth catch the tooth ring, the vertical surface of the check groove blocks the vertical surface of the check teeth, preventing the sleeve from moving back, and the catch teeth and the tooth ring remain in the clamped state, avoiding the change of the position of the float.
[0017] 4、The present application can make fine adjustment to the position of the connecting plate, the sleeve, the sleeve and the catch teeth by rotating the threaded rod. When measuring the resin interface liquid level with high viscosity and density, the floating speed of the float is slow, and the centrifugal force acting on the sleeve is small, so there is no need to worry about the outward movement of the sleeve when the float is floating in the resin. Therefore, the catch teeth can be kept near the tooth ring. If the resin interface liquid level to be measured has relatively small viscosity and density, the floating speed of the float in the resin will be relatively fast. In order to prevent the sleeve from moving outward too much when the float is floating in the resin, the position of the connecting plate can be adjusted to keep the catch teeth at a position slightly away from the tooth ring, preventing the catch teeth from moving outward and catching the tooth ring, which affects the floating of the float in the resin. Different types of resins can be measured, and the applicability is increased. BRIEF DESCRIPTION OF DRAWINGS

[0021] See also Figures 1-10 The present invention provides a technical solution: an interface liquid level measuring device for a resin production process, comprising a tank body 1, a plurality of fixed pulleys 2 mounted on the inner and outer walls of the tank body 1, a float 3 disposed inside the tank body 1, a positioning mechanism 4 mounted on the right side wall of the tank body 1, a guide mechanism 5 disposed on the left side of the positioning mechanism 4, a display mechanism 6 disposed on the guide mechanism 5, a connecting rope 8 connected to the positioning mechanism 4, the connecting rope 8 sequentially passing through the guide mechanism 5 and the fixed pulleys 2 and connected to the bottom of the float 3; The positioning mechanism 4 includes a rotating rod 43 and a rotating column 47. The outer wall of the rotating rod 43 is fixedly connected to the winding roller 44, and the connecting rope 8 is wound around the outer wall of the winding roller 44. The top of the rotating rod 43 is fixedly connected to the driving gear 45, and the outer wall of the rotating column 47 is fixedly connected to the driven gear 48. The top of the rotating column 47 is fixedly connected to the mounting plate 49. A sleeve rod 410 is provided on the right side of the mounting plate 49. The outer wall of the sleeve rod 410 is slidably connected to a sleeve 411. A spring 412 is fixedly connected between the sleeve 411 and the opposite side of the sleeve 410. The right side wall of the sleeve 411 is fixedly connected to a latch 413. A gear ring 415 is provided on the periphery of the sleeve 411. The size of the driving gear 45 is larger than that of the driven gear 48. Each fixed pulley 2 is provided with a limiting structure to prevent the connecting rope 8 from escaping from the surface of the fixed pulley 2. This limiting structure has been maturely applied in the prior art and will not be elaborated in this article. The guide mechanism 5 includes a rotating shaft 52, the outer wall of which is fixedly connected to a guide pulley 53. The display mechanism 6 includes a rotating plate 61, a display panel 66, a fixing bracket 64, and a scale plate 63. The front end of the rotating shaft 52 is fixedly connected to the rotating plate 61, a pointer 62 is fixedly connected to one side of the outer wall of the rotating plate 61, and a photoelectric switch 65 is installed on the inner wall of the fixing bracket 64. The present invention utilizes the speed difference of the float 3 in the resin and in the water to change the motion state of the latch 413 and lock the float 3 at the resin interface, thereby effectively positioning the resin interface.
[0022] When the float 3 floats in the resin, it is affected by the viscosity of the resin and the floating speed is slow. During the floating process, the connecting rope 8 drives the pointer 62 and the latch 413 to rotate. The moment the float 3 floats to the resin interface and enters the water, it gets rid of the viscosity of the resin and the floating speed suddenly accelerates. The rotation speed of the sleeve rod 410 increases greatly, the latch 413 moves and clamps the gear ring 415, and the float 3 stays at the resin interface. The number of circles rotated by the pointer 62 corresponds to the floating distance of the float 3, thereby obtaining the resin interface liquid level.
[0023] In this embodiment, specifically: the float 3 includes a floating seat 31, the outer wall of the floating seat 31 is fixedly connected to a circular groove 32, and the inner bottom wall of the circular groove 32 is evenly provided with through holes 33; the circular groove 32 is opened upward to increase the resistance of the float 3 when floating, increase the adhesion area of the resin, and reduce the floating speed of the float 3. The through holes 33 allow water to pass through smoothly. The outer wall of the floating seat 31 is a conical surface that is narrow at the top and wide at the bottom, which can play a guiding role and prevent the float 3 from turning over.
[0024] In this embodiment, specifically: the guide mechanism 5 also includes two fixed plates 51, the left side walls of the two fixed plates 51 are symmetrically fixedly connected to the right side wall of the tank body 1, and the two ends of the rotating shaft 52 are respectively rotatably connected between the opposite sides of the two fixed plates 51 through bearings. The positioning mechanism 4 also includes a transverse plate 41, the left side wall of the transverse plate 41 is fixedly connected to the right side wall of the tank body 1, and the right side wall of the transverse plate 41 is fixedly connected to the mounting frame 42. The inner side wall of the mounting frame 42 is rotatably connected to the rotating rod 43 through a bearing, and the driven gear 48 is meshed with the driving gear 45.
[0025] Under the above arrangement, the rotation state of the mounting plate 49 and the sleeve rod 410 can be connected to the rotation state of the winding roller 44 by means of the driving gear 45 and the driven gear 48. When the float 3 floats up, the float 3 pulls the connecting rope 8, and the connecting rope 8 drives the winding roller 44 and the driving gear 45 to rotate, and then drives the driven gear 48 and the sleeve rod 410 to rotate. Since the size of the driving gear 45 is larger than that of the driven gear 48, the rotation speed of the driven gear 48 and the sleeve rod 410 is accelerated, and the float The floating speed of the float 3 in the resin is relatively slow, and the centrifugal force on the sleeve 411 is relatively small. Under the pulling force of the spring 1 412, the sleeve 411 is in a force balance state and will not slide outward. When the float 3 reaches the resin interface, it is freed from the influence of the resin adhesion, and the floating speed of the float 3 is instantly accelerated. The centrifugal force on the sleeve 411 is instantly increased, and the sleeve 411 slides outward, driving the locking teeth 413 to clamp the gear ring 415, so that the winding roller 44 stops rotating, and the float 3 stays at the resin interface.
[0026] In this embodiment, specifically: the top of the right side wall of the mounting frame 42 is fixedly connected to a fixed block 46, the bottom of the rotating column 47 is rotatably connected to the upper surface of the fixed block 46 through a bearing, the right side wall of the fixed block 46 is fixedly connected to a support rod 414, and the lower surface of the gear ring 415 is fixedly connected to the top of the support rod 414.
[0027] Specifically in this embodiment, the left side wall top of the sleeve 411 is fixedly connected with a connecting block 416, the upper surface of the connecting block 416 is slidably connected with a square bar 417, the top end of the square bar 417 is fixedly connected with a circular plate 420, the lower surface of the circular plate 420 and the upper surface of the connecting block 416 are fixedly connected with a spring 421, the bottom end of the square bar 417 is fixedly connected with a check tooth 418, the upper surface of the sleeve 410 is uniformly provided with a check groove 419, the right side wall of the check tooth 418 and the check groove 419 is a smooth inclined surface, and the left side wall of the check tooth 418 and the check groove 419 is a smooth vertical surface.
[0028] Under the above setting, during the sliding of the sleeve 411, the check tooth 418 slides on the check groove 419, the smooth inclined surfaces press against each other, the spring 421 repeatedly stretches and contracts, when the catch 413 clamps the tooth ring 415, the vertical surface of the check groove 419 blocks the vertical surface of the check tooth 418, preventing the sleeve 411 from moving back, so that the catch 413 and the tooth ring 415 remain in the clamped state, avoiding the change of the position of the float 3 caused by the continued floating of the float 3.
[0029] Specifically in this embodiment, the outer side wall top of the mounting plate 49 is symmetrically slidably connected with two slide rods 423, the right side wall of the slide rod 423 is fixedly connected with a connecting plate 422, the left end of the sleeve 410 is fixedly connected to the right side wall of the connecting plate 422, the left side wall of the connecting plate 422 is rotatably connected with a threaded rod 424 through a bearing, the threaded rod 424 is threadedly connected with the mounting plate 49, and the left end of the threaded rod 424 is fixedly connected with a handle 425.
[0030] Under the above setting, the position of the connecting plate 422, the sleeve 410, the sleeve 411 and the catch 413 can be finely adjusted by rotating the threaded rod 424. When the resin interface liquid level with large viscosity and density is measured, the float 3 floats slowly, and the sleeve 410 is subjected to very small centrifugal force, so there is no need to worry that the sleeve 411 moves outward when the float 3 floats in the resin, so the catch 413 can be kept close to the tooth ring 415. However, when the resin interface liquid level with relatively small viscosity and density is measured, the float 3 floats relatively fast in the resin. In order to prevent the sleeve 411 from moving outward too much when the float 3 floats in the resin, the position of the connecting plate 422 can be adjusted, so that the catch 413 is kept at a position slightly away from the tooth ring 415, preventing the catch 413 from moving outward and clamping the tooth ring 415, affecting the floating of the float 3 in the resin. Different types of resins can be measured, and the applicability is increased.
[0031] Specifically in this embodiment, the positioning mechanism 4 is provided with a reset mechanism 7, the reset mechanism 7 includes a rotating handle 71, the bottom end of the rotating rod 43 penetrates through the lower surface of the mounting frame 42 and is fixedly connected with the rotating handle 71, the outer side wall bottom of the rotating rod 43 is fixedly connected with a circular ring 73, and the right side wall bottom of the mounting frame 42 is threadedly connected with a jacking rod 72.
[0032] Under the above settings, after completing a measurement, the circular plate 420 is pulled up to disengage the check teeth 418 from the check groove 419, the sleeve 411 returns to the initial position, the clamping teeth 413 no longer clamp the tooth ring 415, rotating the handle 71 drives the winding roller 44 to rotate, the connecting rope 8 is wound, the float 3 returns to the bottom of the tank 1, and the next measurement is prepared, at the same time, the top rod 72 is rotated clockwise, the top rod 72 abuts against the circular ring 73, the circular ring 73 and the winding roller 44 are locked by the friction force, and the float 3 is stopped at the bottom of the tank 1, the surface of the circular ring 73 is rough and cannot easily slip.
[0033] In this embodiment, specifically, the inner bottom wall of the tank 1 is uniformly and fixedly connected with the positioning column 801, and the positioning column 801 is located directly below the float 3.
[0034] The application also provides a use method of the interface liquid level measuring device in the resin production process, which comprises the following steps: S1, through pre-test, the distance that the connecting rope 8 moves when the pointer 62 rotates one circle is recorded as s, the height of the positioning column 801 is recorded as h, and the float 3 is released from the bottom of the tank 1; S2, the float 3 starts to float in the resin, is affected by the resin viscosity, and slowly floats up, in the process of floating up, the float 3 pulls the connecting rope 8, the connecting rope 8 drives the guide pulley 53, the winding roller 44 and the rotating rod 43 to rotate, and the rotating rod 43 drives the driving gear 45, the driven gear 48, the mounting plate 49 and the sleeve rod 410 to rotate; S3, when the float 3 floats up to the resin interface and enters the water, the float 3 suddenly speeds up due to the fact that the float 3 is free from the resin viscosity, the sleeve rod 410 greatly increases the rotating speed, the sleeve 411 slides outward on the sleeve rod 410 under the action of the centrifugal force, drives the clamping teeth 413 to move and clamp the tooth ring 415, the winding roller 44 stops rotating, and the float 3 stays at the resin interface; S4, from the start of the float 3 floating up to the float 3 staying at the resin interface, the interface liquid level of the resin is the distance that the float 3 moves plus the height of the positioning column 801, the number of circles that the pointer 62 rotates corresponds to the distance that the float 3 floats up, the pointer 62 is recorded once by the light-receiving photoelectric switch 65 every time the pointer 62 rotates one circle, the number of circles that the pointer 62 rotates is m according to the scale disc 63, and thus the interface liquid level of the resin is m*s+h.
[0035] In this embodiment, specifically, in S3, in the process of the sleeve 411 sliding, the check teeth 418 slide on the check groove 419, the smooth inclined surfaces are pressed against each other, the spring two 421 repeatedly stretches and contracts, when the clamping teeth 413 clamp the tooth ring 415, the vertical surface of the check groove 419 blocks the vertical surface of the check teeth 418, the sleeve 411 is prevented from moving back, and the clamping teeth 413 and the tooth ring 415 are kept in the clamped state.
