Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to a liquid-liquid two-phase stratification device. Background Art

[0002] Liquid-liquid separation is an indispensable method in the process of chemical and pharmaceutical production and research. There are many liquid-liquid separation devices, and the internal structures of the stratification devices are varied. At present, the commonly used liquid-liquid stratification devices are mainly glass hole observation type and float type. The commonly used glass hole type, because the liquid-liquid interface is inside the separation tank, it is difficult to observe the position of the internal liquid-liquid stratification level, resulting in inoperability. The commonly used float type liquid-liquid separator requires a hole to be opened at the top of the stratifier. The float is located at the top of the liquid-liquid stratifier to observe the up and down movement of the float. However, in the actual operation process, due to the appearance of flocs and emulsified layers at the interface of the two phases, the stratification operation becomes more difficult.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figures 1 to 3As shown, this embodiment provides a liquid-liquid two-phase stratification device, including a shell 1, a two-phase boundary laser detection component is provided on the bottom surface of the shell 1, a transparent partition 101 is provided above the two-phase boundary detection component, the transparent partition 101 is located at the lower part of the inner side of the shell 1 and is sealed and fixedly connected to the inner wall of the shell 1, a feed inlet 107 is provided on the top surface of the shell 1, an electric field boundary detection component is provided on the inner wall of the shell 1, a two-phase boundary surface 9 is located at a height between the top and bottom ends of the electric field boundary detection component, a lower layer liquid outlet 104 is provided at the lower part of the side wall of the shell 1, and the lower interface of the contour is flush with the top surface of the transparent partition 101, an upper layer liquid outlet 105 is provided in the middle part of the side wall of the shell 1, a demulsification component is sleeved on the outer side of the shell 1, the demulsification component is transmission-connected with a lifting component, and the two-phase boundary laser detection component, the electric field boundary detection component, the demulsification component, and the lifting component are electrically connected to a controller.

[0021] When the two-phase liquid is subjected to stratification treatment, the emulsified part at the boundary of the two-phase liquid is quickly broken through the demulsification component. Considering that the height of the emulsified part will change due to the different amounts of two-phase liquid actually added, the demulsification component is connected to the lifting component so that the demulsification component can adapt to the different heights of the emulsification part. The two-phase boundary laser detection component is used to detect the height of the interface of the two-phase liquid to transmit the signal to the controller. The controller further controls the operation of the lifting component to move the demulsification component to a suitable height for demulsification treatment. The electric field boundary detection component cooperates with the demulsification component. When the demulsification process is completed or in progress, the electric field boundary detection component can act on the interface, the upper liquid, and the lower liquid. Due to the different electrical conductivity between layers and at the interface, the electric field boundary detection component can be used to further clearly detect the stratification results and the height of the stratification interface, and the purpose of rapid stratification can be achieved by coordinating the lifting of the demulsification component.

[0022] A further optimized solution is that the two-phase boundary laser detection component includes a plurality of laser emitters 102 fixedly connected to the bottom surface of the shell 1, the plurality of laser emitters 102 are arranged in an array, intervals are reserved between the plurality of laser emitters 102, a plurality of optical fiber receiving ends 103 are arranged between the intervals of the laser emitters 102, a transparent partition 101 is located above the plurality of laser emitters 102 and the optical fiber receiving ends 103, the optical fiber receiving end 103 is connected to the optical fiber, and the optical fiber and the laser emitter 102 are connected to the controller signal.

[0023] The controller controls the laser transmitter 102 to emit light signals at certain intervals. When the emulsification at the interface is serious, its reflection ability is weak and the diffuse reflection ability is strong. The controller is also used to process the signal received by the optical fiber receiving end 103. Several optical fiber receiving ends 103 receive the light emitted by the laser transmitter 102, which can determine the severity of the emulsification at the interface and can cooperate with the demulsification component to quickly achieve rapid demulsification.

[0024] A further optimized solution is that the electric field boundary detection component includes two groups of electrode assemblies, and the two groups of electrode assemblies are symmetrically arranged. The electrode assembly includes a plurality of electrodes 106 arranged vertically, and the electrode 106 is electrically connected to the controller. The electrode 106 is fixedly connected to the shell 1 and is insulated. The two symmetrical electrodes 106 have opposite polarities, and the plurality of electrodes 106 in the same group have the same polarity.

[0025] Since the electrodes 106 in one group are arranged vertically, the resistivity at different heights can be detected to judge the stratification effect during the two-phase stratification process. At the same time, the height of the two-phase stratification interface can be determined to achieve rapid demulsification by coordinating the lifting of the demulsification component.

[0026] According to a further optimized solution, the demulsification assembly includes a slip ring 2 vertically slidably connected to the outside of the shell 1, a plurality of ultrasonic generators 5 are fixedly connected inside the slip ring 2, the ultrasonic generator 5 is electrically connected to the controller, and the slip ring 2 is electrically connected to the lifting assembly.

[0027] When the emulsification component to be broken moves to the height to be broken, the controller controls the ultrasonic generator 5 to operate, and the emulsification effect is quickly broken by ultrasonic waves, thereby effectively enhancing the separation of the two-phase liquid.

[0028] According to a further optimized solution, the lifting assembly includes two motors 4 fixedly connected to the outer wall of the shell 1, the motors 4 are symmetrically arranged, the output shafts of the motors 4 are connected to the screws 3, the screws 3 are threadedly connected to the slip ring 2, the threads of the two screws 3 have the same rotation direction, and the motors 4 are electrically connected to the controller.

[0029] To further optimize the solution, the shell 1 is also provided with a floating interface detection component, which includes a floating rod 7 suspended in the two-phase liquid, the bottom surface of the floating rod 7 is a reflective surface, and a photoelectric transmitter and receiver 8 is provided below the floating rod 7. The photoelectric transmitter and receiver 8 is fixedly connected to the top surface of the transparent partition 101, and a connecting block 6 is slidably connected to the outer side of the floating rod 7, and the connecting block 6 is fixedly connected to the inner wall of the shell 1.

[0030] The controller controls the photoelectric transmitter and receiver 8 to emit light and irradiate the floating rod 7. The reflected light enters the photoelectric transmitter and receiver 8. The height of the floating rod 7 can be determined by the controller's emission interval and reception time, thereby determining the height of the two-phase liquid interface, and cooperating with the demulsification component to break the emulsification effect at the interface.

[0031] The controller used in the present invention can be a controller with control and data calculation functions such as PCL and PC terminal. Its connection and control methods with other components are all existing technologies and will not be described in detail here.

[0032] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
