Description

Technical Field

[0001] This utility model belongs to the technical field of stirring devices, specifically relating to a gas stirring device. Background Technology

[0002] In the food and chemical industries, corrosive agents are commonly used for cleaning, preparation, and dilution. Examples include citric acid, lactic acid, and baking soda. In the food industry, these acidic and alkaline solutions are frequently mixed or diluted to prepare solvents with specific concentrations and properties. Similarly, many of these chemical solutions cannot be in prolonged contact with metals, as prolonged contact can easily lead to chemical reactions and affect solution stability. Using conventional stirrers to mix such corrosive solutions can easily cause corrosion damage to the stirrer and alter the properties of the solution. Researchers have conducted relevant studies on this issue. For example, in the prior art, Chinese utility model patent application number CN201420498154.3 discloses a gas stirring mixer, specifically including a container for holding the stirring liquid and an air pump. Its characteristic is that it also includes a gas guide tube vertically inserted from the top of the container, with a bubbler at the end of the gas guide tube. The bubbler includes a base connected to the end of the gas guide tube, and V-shaped bubble tubes distributed circumferentially on the base, each V-shaped bubble tube having a bubble hole. This invention uses a method of introducing gas into a liquid to stir the liquid. At the same time, it eliminates moving parts, and the gas stirring device has a simple structure, making it suitable for mixing low-viscosity, corrosive or toxic materials.

[0003] However, for chemical solutions that require long-term stirring, existing technologies may lead to operational errors due to human negligence, resulting in problems with stirring time control. Prematurely shutting down the stirring equipment or forgetting to shut it down will affect the solution preparation effect and result in a high energy waste rate. Summary of the Invention

[0006] Preferably, the timing component includes a circuit breaker and a time control element. The circuit breaker is disposed between the time control element and the power supply. The time control element is electrically connected to the solenoid valve and is used to adjust and control the stirring time.

[0007] Preferably, a transformer is provided between the circuit breaker and the time control element, and the transformer is used to adjust the circuit voltage.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figures 1 to 2This application provides a gas stirring device, including: a solvent tank 100, a gas compression assembly 200, and a timing assembly 300. The solvent tank 100 is equipped with a jetting component, which sprays gas into the solvent tank 100 and stirs the solution within it. The gas compression assembly 200 includes a compression chamber 210, a gas pipeline 220, and a solenoid valve 230. The compression chamber 210 is connected to a power supply 130. One end of the gas pipeline 220 is connected to the compression chamber 210, and the other end is connected to the solenoid valve 230. The solenoid valve 230 switches the gas pipeline 220 between a closed and an open state, and the other end is connected to the jetting component. One end of the timing assembly 300 is connected to the power supply 130, and the other end is electrically connected to the solenoid valve 230. The timing assembly 300 controls the solenoid valve 230.

[0022] Specifically, the jetting components employ, but are not limited to, permeable bricks, gas-assisted injection (GAIM) nozzles, and porous titanium plates. The solvent tank 100 is a common stirring or holding container for gas stirring or corrosive solutions in the chemical industry. The timing component 300 uses mechanical or electronic timing devices, such as a weighted timer, an hourglass / water clock, a pneumatic delay device, a programmable digital timer, or a knob-wound timer. For mechanical timers (taking a knob-wound timer as an example), manually rotating the knob winds up the mainspring, and the elastic potential energy of the mainspring drives the gear set to rotate at a constant speed. Then, the cam rotates with the gears to push the contacts to open / close the circuit, thereby achieving the timing function. There are also many existing technologies using electronic components, such as the electronic timing switch disclosed in patent number CN87215336U. There are many devices, all of which can achieve the timing function. Their specific structures are all existing technologies and will not be described in detail here. The solenoid valve 230 has a closed state and an open state. When the solenoid valve 230 is in the closed state, it covers the gas pipeline 220, disconnecting its gas phase space from the gas phase space of the jet component. When the solenoid valve 230 is in the open state, the gas phase space of the gas pipeline 220 is connected to the gas phase space of the jet component. The solenoid valve 230 is, but is not limited to, a two-position two-way solenoid valve 230, an ASCO551, etc. The compression box 210 is connected to the compressor gas storage 240. The compressor gas storage 240 controls the compression box 210, and the compression box 210 compresses the gas under the control of the power supply 130.

[0023] Further, the solution is introduced into the solvent tank 100, and the power supply 130 is turned on. The compressor 210 operates, and the stored clean gas is blocked at the solenoid valve 230 from the gas pipeline 220. At the same time, the timing component 300 starts working when the power supply 130 is turned on, and the operator sets the stirring time. After the time is set, the solenoid valve 230 switches from the closed state to the open state. At this time, the compressed gas passes through the solenoid valve 230 and enters the jetting component, which then sprays the compressed gas into the solvent tank 100 to stir and mix the solution inside. When the preset time is reached, the timing component 300 controls the solenoid valve 230 to switch from the open state to the closed state, thereby stopping the gas from entering and completing the timed stirring. To achieve the desired gas flow rate (stirring speed), a gas flow rate control valve (e.g., a one-way throttle valve, made of stainless steel (e.g., 304 / 316) or a specially coated valve body) can be installed between the solenoid valve 230 and the solvent tank 100. This valve is also protected with an anti-corrosion coating. The gas flow rate is controlled by the threshold of the gas flow rate control valve. Adjustments are made to meet the different stirring speed requirements of different solutions.

[0024] Furthermore, for different solutions, other inert gases can be introduced internally, such as sterile / clean nitrogen. The timing component 300 presets the stirring time and interval, solving the problem of difficulty in controlling the stirring time after stirring for some solutions that require a period of settling.

[0025] The technical solution of the gas stirring device adopted in this application can achieve the following beneficial effects: 1. By setting the timer component 300, the problem of some test solutions requiring long-term stirring is solved. Excessive stirring time can lead to operators being unable to determine the stirring time, resulting in premature shutdown of the stirring equipment or operators forgetting to stir.

[0026] 2. By using gas stirring, the problem of chemical solutions not being able to come into contact with metals, as contact can easily lead to chemical reactions that affect solution stability is solved. Clean compressed inert gas is used for gas stirring to solve the problem of uneven solution dissolution.

[0027] Based on the above scheme, the timing component 300 includes a circuit breaker 310 and a time control component 330. The circuit breaker 310 is disposed between the time control component 330 and the power supply 130. The time control component 330 is electrically connected to the solenoid valve 230 and is used to adjust and control the stirring time.

[0028] Specifically, circuit breaker 310 is a residual current circuit breaker, specifically a 220V air switch residual current circuit breaker 310, responsible for connecting the power supply 130 of the entire device. It is a switch with short-circuit, overheat, and leakage protection, and features manual reset and automatic trip protection. The time control element 330 can be either electronic or mechanical. If it is mechanical, it starts working (internally requiring a motor to drive gears or cams to rotate) after the circuit breaker 310 connects the circuit; if it is electronic, it opens when energized. By setting circuit breaker 310 to protect the power supply 130, operation is made safer.

[0029] Furthermore, the compressor box 210 is directly electrically connected to the circuit breaker 310 and is no longer electrically connected to the power supply 130. When a problem occurs, both the time control unit 330 and the compressor box 210 disconnect the circuit, thus solving the problem of circuit failure causing some equipment directly connected to the power supply 130 to continue to work and thus causing damage.

[0030] In the above scheme, a transformer 320 is provided between the circuit breaker 310 and the time control unit 330. The transformer 320 is used to adjust the circuit voltage. The transformer 320 is a 220VAC to 24VDC converter. By changing the current provided by the power supply 130 through the transformer, it is more in line with the current input of the time control unit 330, thus better protecting the time control unit 330.

[0031] In a further embodiment, the time control component 330 is a KG317T-50 overcapacity control switch. Using the KG317T-50 overcapacity control switch is one implementation method; it is simple and convenient to operate and allows for multi-segment or single-segment time settings, such as stirring for 30 minutes every hour, or stirring several times.

[0032] Furthermore, the time control unit 330 is adjusted for time control. The output (live wire L) is connected to the positive terminal of the coil of the 220VAC intermediate relay. The negative terminal of the intermediate relay coil is connected to the negative terminal (neutral wire N) of the 220V power supply 130. One end of the normally open contact of the intermediate relay is connected to the positive terminal (24VDC) of the output of the 220VAC / 24VDC switching power supply 130, and the other end is connected to the input terminal of the coil of the 24VDC solenoid valve 230. The output terminal of the coil of the 24VDC solenoid valve 230 is connected to the negative terminal (N) of the output of the 220VAC / 24VDC switching power supply 130. At this time, the solenoid valve 230 receives control from the time control unit 330.

[0033] Please see Figure 1 In one embodiment of this application, the jetting element is an annularly distributed air pipe 111, and the air pipe 111 is provided with a plurality of equidistantly distributed unidirectional exhaust ports.

[0034] The gas pipe 111 is made of plastic, PVC, stainless steel, or a corrosion-resistant material, and is arranged in a ring along the inner wall of the solvent tank 100. Several 1mm one-way exhaust holes are provided on the gas pipe 111, with a 5mm spacing between adjacent exhaust holes. Compressed inert gas is uniformly released outward through the exhaust holes to achieve gas stirring. Multiple gas inlets are provided, distributed at different heights and angles, to promote thorough mixing of the gas within the chamber.

[0035] Please see Figure 2 In another embodiment of this application, the jetting element is a gas distributor 112 disposed at the bottom of the solvent tank 100, the gas distributor 112 being used to release gas to the surroundings.

[0036] A gas distributor 112 is located at the center of the bottom of the solvent tank 100. The gas distributor 112 is 10mm long and 2mm in diameter (the exact diameter depends on the tank diameter). It uniformly releases compressed inert gas to achieve gas agitation (the holes on the gas distributor 112 are all angled, allowing the gas to rotate the solution). It is made of high-strength, corrosion-resistant, and environmentally friendly materials (such as stainless steel or special plastics) to ensure long-term stability and safety. The compressed inert gas pipeline is designed in a circular, elliptical, or vertical spiral shape to reduce gas flow resistance and improve agitation efficiency.

[0037] Based on the above scheme, a connector 120 is provided at the connection between the gas pipeline 220 and the jet component. The connector 120 is any one of a stainless steel quick-connect connector, a PVC quick-connect connector, or a plastic quick-connect connector.

[0038] By setting the connector 120, installation and removal are made more convenient and subsequent maintenance is easier. Any one of stainless steel quick connectors, PVC quick connectors, and plastic quick connectors can be used to solve the problem of corrosive solutions flowing out from the connection and corroding the connector 120, thereby reducing its service life.

[0039] Furthermore, both the solvent tank 100 and the jetting component are coated with an anti-corrosion coating. By applying the anti-corrosion coating, the corrosion of the solvent tank 100 and the jetting component by the corrosive solution is reduced. The anti-corrosion coating may be, but is not limited to, epoxy coal tar pitch, polyurethane coating, or composite ceramic coating.

[0040] Traditional solid-state stirring fans directly propel liquid flow through mechanical blades, which can easily create local eddies or dead zones, resulting in uneven liquid mixing, especially in complex cavities or large-volume spaces where the concentration gradient of liquid components is significant. However, the solution in this application adopts a multi-dimensional air inlet design (such as multi-angle and multi-height distribution) and a spiral stirring air pipe 111, combined with magnetic drive technology, to generate a three-dimensional vortex flow field, eliminating the "stirring blind zone" of traditional fans and achieving uniform mixing of liquid molecules.

[0041] Traditional high-speed rotating blades may generate noise pollution and pose safety hazards in flammable and explosive gas environments. In contrast, this application features a fully enclosed chamber design that isolates external pollution, and a magnetic valve-controlled clean compression inert gas technology that eliminates mechanical friction noise, resulting in significantly reduced operating noise.

[0042] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
