Description

Technical Field

[0001] The utility model relates to the technical field of liquid mixing processing, in particular to a novel liquid mixing machine. Background Art

[0002] A liquid mixer is a device widely used in the chemical, food, pharmaceutical and other industries. It is used to accurately mix two or more liquid components in a specific proportion to form a uniform solution or emulsion. Traditional liquid mixers are usually equipped with a mixing tank in which the liquids are proportioned and stirred. During operation, the liquid components are transported to the mixing tank through pipes and mixed by mechanical stirring or other forms of agitation. The mixed liquid is then transported to the next step of processing or storage through the outlet pipe.

[0003] The existing single mixing tank technology has obvious defects: since mixing and discharging cannot be carried out at the same time, there will be interruptions in the production process, resulting in the need for discharging to wait until mixing is completed, which seriously affects production efficiency and cannot meet the needs of continuous production. Even if a storage tank is equipped, when the discharging rate exceeds the mixing rate, there is still a risk of discharging interruption, which will lead to unstable production processes, making it difficult to ensure continuous product supply, affecting process continuity, and ultimately causing product quality to decline or even produce defective products.

[0108] When the fifth valve and the seventh liquid level cannot detect the presence of liquid in the first mixing tank or the second mixing tank, the first valve, the third valve, the water pump and the mixing pump are opened, the water flow device starts to control the amount of water entering the first mixing tank according to a preset ratio, and the raw liquid flow device starts to control the amount of raw liquid entering the first mixing tank according to a preset ratio, and the total amount of raw liquid entering the first mixing tank does not exceed 40L;

[0109] When the fourth liquid level detects that the amount of the first liquid mixing tank reaches a high liquid level, the water pump, the liquid mixing pump, the first valve, and the third valve are turned off, and at the same time, the first liquid mixing tank starts mixing processing and starts a preset mixing timer;

[0110] If the fourth liquid level fails to detect that the amount in the first liquid mixing tank has reached a high liquid level, the high liquid level alarm of the first liquid mixing tank is activated to shut down;

[0111] After the timing is completed, the fifth valve is opened to discharge the liquid, and the set time is started at the same time. If the set time is exceeded, the fifth valve lights up, and the mixing first mixing tank is started to discharge the liquid overtime alarm and stop;

[0112] When the first mixing tank starts for a set time, the second valve, the fourth valve, the water pump, and the mixing pump are turned on, the water flow device starts to control the amount of water entering the second mixing tank according to a preset ratio, and the raw liquid flow device starts to control the amount of raw liquid entering the second mixing tank according to a preset ratio, and the total amount of raw liquid entering the first mixing tank does not exceed 40L;

[0113] When the fourth liquid level detects that the amount of the second liquid mixing tank reaches a high liquid level, the water pump, the liquid mixing pump, the second valve, and the fourth valve are turned off, and at the same time, the second liquid mixing tank starts mixing processing and starts a preset mixing timer;

[0115] After the timing is completed, open the fifth valve to discharge the liquid, and start the set time at the same time. If the set time is exceeded, the fifth valve lights up, and the mixing second mixing tank is started to discharge the liquid overtime alarm and stop;

[0116] If the liquid level in the storage tank is lower than the low liquid level, the liquid outlet pipe is closed and the device enters the liquid preparation waiting state. When the device completes the liquid preparation and replenishes the storage tank to the middle liquid level, the liquid outlet pipe is opened. At this time, x9 no longer detects the preset quantitative liquid supply value and only displays the flow count.

[0117] The working principle of the utility model is roughly as follows:

[0118] When working, according to the preset liquid supply state, the first, second and third liquid level information in the liquid storage tank is collected. Based on this information, the system controls the water pump and the raw liquid pump to transport the liquid to the first and second mixing tanks in a predetermined proportion through the water pipe and the raw liquid pipe;

[0119] Each mixing tank controls the inflow and outflow of liquid through an electric ball valve, and monitors the liquid flow through a metering device to ensure the accuracy of the mixing ratio. After mixing, the mixed liquid is transported out of the machine through the liquid outlet pipe.

[0120] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
