All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are also within the scope of the application.

As shown in fig. 1, the present application provides a liquid dropping device, which comprises a liquid storage tank 1 and a liquid distribution pipe 21 connected by a first electromagnetic valve 100, wherein the liquid distribution pipe 21 is arranged in a device 2 to be added with liquid;

The liquid storage tank 1 is also connected with the air charging tank 3 through a second electromagnetic valve 200 and a check valve 300 in sequence;

The air charging tank 3 is also connected with a spraying device 22 arranged in the device 2 to be charged with liquid through a pressure valve 400;

the top of the liquid adding device 2 is provided with a pressure relief opening 201.

In the application, the device 2 to be added with liquid is a container such as a reaction kettle, a crystallization kettle and the like in a factory, which needs to be added with liquid in a dripping way.

According to the application, the aeration tank 3 and the compressed gas storage tank 4 are arranged, the gas in the compressed gas storage tank 4 is utilized to aerate the liquid in the aeration tank 3, the injected gas can form tiny bubbles under the action of the aeration pipe 31, and when the liquid containing the bubbles is sprayed out from the spraying device 22, the sprayed liquid is broken into tiny liquid drops due to expansion and breaking of the bubbles, so that the liquid can be uniformly added into the kettle, and the flow rate of the liquid in the kettle can be improved due to the fact that the liquid is sprayed out under pressure, so that the requirement of a large amount of liquid adding is met. Meanwhile, as the liquid is sprayed out, the liquid added into the kettle is added in the form of tiny liquid drops, and the distribution of the liquid drops is more uniform under the spraying state, so that adverse effects caused by overhigh local liquid concentration due to common dripping can be avoided.

When in use, when a small amount of liquid is required to be added dropwise, the second electromagnetic valve 200 is closed, the first electromagnetic valve 100 is opened, the opening of the first electromagnetic valve 100 is regulated, liquid (such as acetone or aqueous solution) in the liquid storage tank 1 enters the liquid distribution pipe 21 under the action of gravity to uniformly drop the liquid into the liquid to-be-added device 2, and meanwhile, the stirring paddles in the liquid to-be-added device 2 are driven by the motor to stir, so that the added liquid and the materials in the kettle are mixed more uniformly.

When a large amount of liquid is required to be dropped, the first solenoid valve 100 is closed, and the second solenoid valve 200 is opened, and the liquid in the liquid tank 1 flows into the gas-filled tank 3. When the height in the tank reaches the preset high level, the second electromagnetic valve 200 is closed, the third electromagnetic valve 500 is opened, the compressed gas (such as compressed air or nitrogen) in the compressed gas storage tank 4 is filled into the liquid in the aeration tank 3, when the pressure in the aeration tank 3 reaches a certain value (such as 0.2-0.7 MPa), the pressure valve 400 is opened, and the aerated liquid with pressure enters the spraying device 22 through the pipeline.

The aerated liquid enters the spraying device 22 and is sprayed out, and because the gas is filled in the liquid, sprayed liquid drops are finer, and the defect that the liquid can flow down in a straying way and cannot be added uniformly when a large amount of liquid is dropped by a porous dropper is avoided. Since the injected liquid is filled with gas, the gas is released after the liquid is sprayed, and in order to avoid the gradual increase of the gas pressure in the liquid adding device 2 caused by the gas, the gas is discharged from the pressure relief opening 201 arranged on the liquid adding device 2 for subsequent treatment.

The application provides a liquid dripping device, which is characterized in that a liquid distribution pipe 21 connected with a liquid storage tank 1 is arranged in a device 2 to be added with liquid to meet the requirement of dripping liquid at a small amount and an inflating tank 3 connected with the liquid storage tank 1 is arranged, the inflated liquid is inflated and pressurized by a compressed gas storage tank 4 to the liquid of the inflating tank 3, the inflated liquid is accelerated and evenly sprayed out by a spraying device 22, the requirement of dripping liquid at a large amount is met, and the defects that the existing device for dripping liquid is uneven in liquid adding and easy to cause overlarge local liquid adding concentration during quick and massive liquid adding are overcome.

The time division liquid pipe 213 is arranged at a position higher than Yu Di liquid pipes 211, and the time division liquid pipe 213 is communicated with the liquid dropping pipe 211 through a plurality of communicating pipes 212 in order to ensure uniform distribution when the liquid is dropped.

As shown in fig. 2 and 3, the spraying device 22 optionally includes an annular guide pipe 221, and a plurality of atomizing nozzles 222 are connected to the lower surface of the guide pipe 221.

The atomizer 222 includes a first nozzle and a second nozzle; the first spray head is vertically arranged; the second spray head is inclined to the axis direction of the device 2 to be added, the inclination angle is 15-30 degrees, and the phenomenon that local concentration near the wall area is overlarge due to the fact that liquid is sprayed onto the wall of a container when sprayed out is avoided; the first spray heads and the second spray heads are adjacently arranged in a staggered manner so that liquid can be uniformly sprayed into materials in the kettle. Accordingly, the spray area of the spray head can also be adjusted to prevent liquid from being dispensed onto the container wall.

The annular guide pipe 221 and the annular drip pipe 211 can be concentrically arranged on the same plane, and the size of the annular shape surrounded by the guide pipe 221 or the drip pipe 211 can be adjusted according to actual needs during arrangement.

In the present application, when the spraying device 22 is used for filling liquid, since the injected liquid is filled with gas, the gas is released after the liquid is sprayed, and in order to avoid the gradual increase of the gas pressure in the device 2 to be filled, the pressure relief opening 201 formed on the device 2 to be filled discharges the gas. The discharged gas carries the sprayed liquid droplets, so that the gas discharged from the pressure relief port 201 is led into the gas-liquid separator 6 for separation, the separated liquid is returned to the liquid storage tank 1 for recovery so as to reduce resource waste, and the separated gas (containing a small amount of organic matters from the liquid organic matters in the liquid charging device 2) is discharged into the incinerator 7 for incineration for harmless treatment.

A liquid dripping device has the following working process:

When in use, when a small amount of liquid is required to be dripped, the second electromagnetic valve 200 is closed by the controller 5, the first electromagnetic valve 100 is opened, the opening of the first electromagnetic valve 100 is regulated, liquid (such as acetone or aqueous solution) in the liquid storage tank 1 enters the liquid distribution pipe 213 in the liquid distribution pipe 21 under the action of gravity, then the liquid enters the liquid dripping pipe 211 by the communicating pipes 212 communicating the liquid distribution pipe 213 and the liquid dripping pipe 211, the liquid is uniformly dripped into the liquid to-be-added device 2 through the liquid distribution holes formed in the lower surface of the liquid dripping pipe 211, and meanwhile, the stirring paddles in the liquid to-be-added device 2 are stirred under the driving of the motor, so that the dripped liquid and the material in the kettle are more uniformly mixed.

When a large amount of liquid is required to be dropped, the first solenoid valve 100 is closed and the second solenoid valve 200 is opened by the controller 5, and the liquid in the liquid tank 1 flows into the air charge tank 3. Meanwhile, the liquid level gauge 32 arranged in the aeration tank 3 monitors the liquid level height in the aeration tank 3 in real time, and feeds back the liquid level height data to the controller 5, when the height in the tank reaches the preset high level, the controller 5 controls the second electromagnetic valve 200 to be closed, simultaneously controls the third electromagnetic valve 500 to be opened, charges the compressed gas (such as compressed air or nitrogen) in the compressed gas storage tank 4 into the liquid in the aeration tank 3 through the gas-liquid mixer 312, and when the pressure in the aeration tank 3 reaches a certain value (such as 0.2-0.7 MPa), the pressure valve 400 is opened, and the aerated liquid with pressure enters the spraying device 22 through the pipeline.

The aerated liquid enters the annular flow guide pipe 221 in the spray device 22 and is sprayed out through the atomization nozzle 222, and because the gas is filled in the liquid, the sprayed liquid drops are finer, and the defect that the liquid can flow down in a stranding manner and cannot be added uniformly when a large amount of liquid is dropped by a porous dropper is avoided. Since the injected liquid is filled with gas, the gas is released after the liquid is sprayed, and in order to avoid the gradual increase of the gas pressure in the device 2 to be added, the gas is discharged from a pressure relief opening 201 formed in the device 2 to be added. The discharged gas carries the sprayed liquid droplets, so that the gas discharged from the pressure relief port 201 is led into the gas-liquid separator 6 for separation, the separated liquid is returned to the liquid storage tank 1 for recovery so as to reduce resource waste, and the separated gas is discharged into the incinerator 7 for incineration for harmless treatment.
