[0002] When treating sewage in polluted waters, a common method is to add chemicals to the sewage in a targeted manner. Commonly used chemicals include flocculants, coagulants, conditioners, demulsifiers, etc. The chemicals are formulated according to the size of the water area and then added to the sewage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3, the utility model discloses a medicine dosing device for water pollution treatment, including a support 1, on which an electric control box 2, an ultrasonic generator 3, a solution tank 4 and a metering pump 5 are respectively installed, and the ultrasonic generator 3 and the metering pump 5 are electrically connected to the electric control box 2 respectively. The inlet end of the metering pump 5 is connected to the solution tank 4 through a pipeline, and its outlet end is connected with a liquid outlet pipe 6. A feeding hopper 7 is installed on the top of the solution tank 4, and a driving motor 8 is installed on the side wall of the feeding hopper 7. A feeding roller 9 is installed in the feeding hopper 7 through a bearing, and one end of the feeding roller 9 is fixedly connected to the output shaft end of the driving motor 8. A reduction motor 10 is installed on the top of the solution tank 4, and a stirring shaft 11 is installed in the solution tank 4 through a bearing. The top end of the stirring shaft 11 is fixedly connected to the output shaft end of the reduction motor 10. Stirring blades 12 and a homogenizing head 13 are successively installed on the stirring shaft 11. Ultrasonic transducers 14 are installed on the outer walls around the solution tank 4, and the ultrasonic transducers 14 are electrically connected to the ultrasonic generator 3. A feeder is installed in the feeding hopper 7, which can provide a stable feeding capacity, and control the feeding speed of the feeder according to the actual requirements of medicine preparation, so as to avoid the phenomenon that the medicine powder enters the solution tank 4 at one time and caking occurs, resulting in uneven mixing. The reduction motor 10 drives the stirring shaft 11 to mix the solution, and the homogenizing head 13 thereon can make the material reach a highly dispersed effect in a short time, and cooperate with ultrasonic oscillation to generate a strong cavitation effect, break the intermolecular structure of the substance, accelerate its dissolution process, and improve the mixing efficiency.

[0019] Specifically, a liquid discharge port 15 is provided at the bottom of the solution tank 4, and the liquid discharge port 15 is connected to the inlet end of the metering pump 5 through a pipeline.

[0020] In this embodiment, the liquid discharge port 15 is used to be connected to the metering pump 5 through a pipeline, so as to supply liquid through the metering pump 5.

[0021] Specifically, a ball valve 16 and a Y-type filter 17 are successively installed on the pipeline connecting the metering pump 5 and the liquid discharge port 15, and a check valve 18 is installed on the liquid outlet pipe 6.

[0022] In this embodiment, the ball valve 16 is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The Y-type filter 17 belongs to a pipeline coarse filter, which can be used for filtering large particles in liquids, gases or other cut-offs. Installed on the pipeline, it can remove larger solid impurities in the fluid. The check valve 18 is a kind of valve, and its main function is to prevent the medium (liquid or gas) from flowing back in the pipeline system. This kind of valve realizes the opening and closing state depending on the flow pressure of the medium itself and the self-weight of the valve flap, ensuring that the medium can only flow in one direction.

[0023] Specifically, a liquid level transmitter 19 is installed on the solution tank 4, and the liquid level transmitter 19 is electrically connected to the electric control box 2.

[0024] In this embodiment, the main function of the liquid level transmitter 19 is to convert the liquid level height into a standard signal, such as 4 to 20 mA or 0 to 10 V, and transmit the signal to the control system so that the control system can monitor and control according to these signals.

[0025] Specifically, a sampling port 20 is provided on the outer wall of the solution tank 4 , and a stop valve 21 is installed on the sampling port 20 .

[0026] In this embodiment, the sampling port 20 is mainly used to obtain samples from a production device, a container or a pipeline, and the stop valve 21 is mainly used to cut off and throttle the pipeline system or the production device.

[0027] Specifically, the outer walls of the solution box 4 are provided with strip-shaped grooves 22 , and the ultrasonic transducer 14 is fixed in the strip-shaped grooves 22 .

[0028] In this embodiment, the strip groove 22 is an assembly structure. The principle of ultrasonic emulsification is that under the action of ultrasonic energy, two or more immiscible liquids are mixed evenly to form a dispersed system, in which one liquid is evenly distributed in another liquid, thereby forming an emulsion process. This process relies on the cavitation effect of ultrasonic waves, that is, under the action of strong ultrasonic waves, a large number of bubbles are generated in the liquid. These small bubbles gradually grow and increase with the ultrasonic vibration, and then suddenly burst and split. The split bubbles continue to grow and burst. When these small bubbles collapse rapidly, high temperature and high pressure are generated in the bubbles. Because the liquid around the bubbles rushes into the bubbles at high speed, a strong microjet is generated in the liquid near the bubbles, forming local high temperature and high pressure, thereby producing a crushing and emulsification effect.

[0029] When in use, a feeder is installed in the feeding hopper 7, which can provide a stable feeding capacity. The feeding speed of the feeder is controlled according to the actual needs of the drug preparation, so as to avoid the phenomenon of uneven mixing caused by the drug powder entering the solution box 4 at one time. The solution is mixed by driving the stirring shaft 11 through the reduction motor 10. The homogenizing head 13 thereon can make the material achieve a highly dispersed effect in a shorter time, and cooperate with ultrasonic oscillation to produce a strong cavitation effect, break the intermolecular structure of the substance, accelerate its dissolution process, and improve the mixing efficiency.

[0030] In summary, for the chemical dosing device for water pollution treatment, a material distributor is installed in the feeding hopper 7, which can provide stable feeding capacity. The feeding speed of the material distributor is controlled according to the actual requirements of chemical preparation, so as to avoid the phenomenon that the powder enters the solution tank 4 at one time and agglomerates, resulting in uneven mixing. The stirring shaft 11 is driven by the reduction motor 10 to mix the solution. The homogenizing head 13 thereon can make the materials achieve a highly dispersed effect in a short time, and cooperate with ultrasonic oscillation to generate a strong cavitation effect, break the intermolecular structure of the substances, accelerate the dissolution process, and improve the mixing efficiency.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
