Description

Technical Field

[0001] The invention belongs to the technical field of foaming cleaning, and in particular relates to an environmentally friendly foaming machine based on ultrasonic technology. Background Art

[0002] A foaming machine, also known as a foam generator, is a device that makes foam from an aqueous solution of a foaming agent to a certain concentration. The foaming agent itself cannot automatically become foam and must be mechanically acted upon by the foaming machine to become foam. Regardless of the type of foaming machine, the basic principle of foaming is to introduce air into the foaming agent solution. The differences among various models lie in the different ways of introducing gas, and thus the effects are also different.

[0003] After searching, the publication number: CN214918948U announced a sponge foaming machine with a stirring function. The user pours the foaming agent and additives into the bin body, starts the hydraulic push rod to drive the support plate to descend, so that the cover plate descends to cover the bin body, and the stirring rod is moved into the bin body. Then, the air pump is started to discharge the clean gas filtered by the filter into the bin body through the outlet pipe, and the rotating motor is started to drive the stirring rod to rotate for mixing and foaming, and the scraper is driven to rotate to scrape off the foam stuck to the inner wall of the bin body, and finally the foaming is completed.

[0004] Although the above patent uses ultrasonic vibration to produce cavitation effect in liquid and then form bubbles, in order to diffuse the cleaning wave to the greatest extent and improve the cleaning effect, the transducer is generally installed near the center of the cleaning box. This can make the ultrasonic beam evenly distributed in the entire cleaning liquid, so as to effectively clean the items. However, for the cleaning of large-sized workpieces, a certain sound field distribution will be formed when the ultrasonic wave propagates in the liquid. For large workpieces, due to their large size, the distribution of the sound field may be changed, resulting in a weakening of the cleaning effect on both sides, thereby reducing the cleaning strength, and the waste from cleaning is not easy to recycle, and direct discharge does not take advantage of industrial environmental protection.

[0005] Therefore, an environmentally friendly foaming machine based on ultrasonic technology is designed to solve the above problems. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-8 An environmentally friendly foaming machine based on ultrasonic technology is shown: comprising a foaming pool 1, an ultrasonic transducer 2, a horizontal blowing air intake component 3, a stirring component 4, a waste recovery component 5 and a feeding component 6, wherein the horizontal blowing air intake component 3 is threadedly connected to the outside of the foaming pool 1, the ultrasonic transducer 2 is threadedly connected to the bottom of the foaming pool 1, the stirring component 4 is fixedly connected to the inside of the foaming pool 1, the waste recovery component 5 is movably connected to the top of the foaming pool 1, and the feeding component 6 is installed on one side of the foaming pool 1; The foaming pool 1 is used for placing the cleaning workpiece, the ultrasonic transducer 2 forms bubbles by converting electrical energy into high-frequency sound waves and removes stains through gentle pressure pulses through bubble bursting, the horizontal blowing air intake component 3 is used to increase the air intake inside the foaming pool 1, the stirring component 4 is used to stir the solution inside the foaming pool 1 to promote the uniform distribution and rapid movement of bubbles in the liquid, the waste recovery component 5 is used to absorb the waste residue blown to the top of the foaming pool 1, and the feeding component 6 is used for the water in and out of the foaming pool 1.

[0023] After the cleaning liquid is injected, the ultrasonic transducer 2 starts working, converting electrical energy into high-frequency sound waves. These sound waves form tiny bubbles in the cleaning liquid, which expand and burst rapidly under the action of the sound waves, generating gentle pressure pulses. These pulses can penetrate the tiny gaps on the surface of the workpiece and effectively remove stains and attachments. The ultrasonic transducers 2 of the device are symmetrically distributed at the bottom of the foaming pool 1 and do not contact the workpiece. The introduction of the transverse air intake component 3 not only increases the air intake inside the foaming pool 1, but also helps the uniform distribution and rapid movement of bubbles in the liquid. This helps the bubbles to contact the surface of the workpiece more effectively, reduces the interference of the workpiece on the sound field distribution, and ensures that all parts of the workpiece can receive uniform and effective ultrasonic cleaning, thereby significantly improving the cleaning effect and cleaning strength.

[0024] The transverse air intake assembly 3 includes a Roots blower 31, an air intake pipe 32, a butterfly aerator 33 and a fixed plate 34. The fixed plate 34 is fixedly connected to the outside of the foaming pool 1. The Roots blower 31 is threadedly connected to the top of the fixed plate 34. The air intake pipe 32 is fixedly connected to the outside of the output end of the Roots blower 31. The butterfly aerator 33 penetrates the inner wall of one side of the foaming pool 1 and is fixedly connected to the outside of the air intake pipe 32.

[0025] The stirring assembly 4 includes a positioning plate 41, a DC motor 42, a corrosion-resistant shaft 43 and a stirring rod 44. The positioning plate 41 is fixedly connected to the top of the foaming pool 1, the DC motor 42 is installed in the middle of the top of the positioning plate 41, the corrosion-resistant shaft 43 is fixedly connected below the output end of the DC motor 42, and the stirring rod 44 is welded and fixed to the outer wall surface of the corrosion-resistant shaft 43.

[0026] In order to disrupt the directional flow effect of the internal solution, the DC motor 42 can be started through the control end. The DC motor 42 drives the corrosion-resistant shaft 43 and the stirring rod 44 to rotate. The stirring rod 44 stirs the cleaning liquid inside the foaming pool 1, further promoting the uniform distribution and rapid movement of bubbles in the liquid, ensuring that the cleaning liquid can fully contact the workpiece surface and improve the cleaning efficiency.

[0027] The stirring action of the stirring component 4 of the device not only helps to evenly distribute the bubbles, but also accelerates the suspension and dispersion of the waste, making it easier to be captured by the waste recovery component 5. The waste recovery component 5 absorbs the waste residue blown to the top of the foaming pool 1, thereby realizing the centralized recovery and treatment of the waste, avoiding the pollution of the environment by direct discharge, and meeting the requirements of industrial environmental protection.

[0028] The waste recovery component 5 includes a support frame 51, a pushing cylinder 52, a push rod 53, a metal telescopic tube 54, a clamping plate 55, a waste tube 56 and a suction head 57. The support frame 51 is fixedly connected to the top of the foaming pool 1, the piston end of the pushing cylinder 52 is fixedly connected to the top of the push rod 53, the top of the metal telescopic tube 54 is fixedly connected to one end of the waste tube 56, the clamping plate 55 is clamped on the outside of the metal telescopic tube 54, the bottom of the push rod 53 is fixedly connected to the two sides of the clamping plate 55, and the suction head 57 is fixedly connected to the bottom of the metal telescopic tube 54.

[0029] The feeding assembly 6 includes a water suction pump 61, a water inlet pipe 62, a drainage pump 63 and a slag pipe 64. The output end of the water suction pump 61 is fixedly connected to the bottom of the water inlet pipe 62. The top of the water inlet pipe 62 passes through one side of the top of the foaming pool 1 and fits tightly with the inner surface of the foaming pool 1. The input end of the drainage pump 63 passes through the other side of the bottom of the foaming pool 1 and fits tightly with the inner surface of the foaming pool 1. The slag pipe 64 is fixedly connected to the outside of the output end of the drainage pump 63.

[0030] The foaming pool 1 is located on both sides of the ultrasonic transducer 2 and is fixedly connected to a placement table 7 .

[0031] A sewage pump 8 is also installed on one side of the waste pipe 56 .

[0032] The design of the feeding component 6 of the device makes the water inlet and outlet operations inside the foaming pool 1 more flexible and convenient to meet the cleaning needs of different workpieces, and can also quickly discharge waste water after cleaning, reducing the waiting time during the cleaning process.

[0033] The waste pipe 56 is located below the bottom of the sewage pump 8 and is also provided with a slag collection frame 9 .

[0034] Waste and liquid wastewater are put into the slag collection frame 9 along the bottom of the waste pipe 56 to prevent them from entering the drainage system and causing environmental pollution. After the cleaning is completed, the drainage pump 63 discharges the cleaning liquid in the foaming pool 1 through the slag pipe 64 to prepare for the next cleaning. At the same time, the design of the slag pipe 64 also ensures that the solid waste in the cleaning liquid can be effectively separated to prevent clogging the drainage system. The entire cleaning process can be circulated until the workpiece reaches the expected cleanliness.

[0035] Four groups of corrosion-resistant shafts 43 are provided, and the four groups of corrosion-resistant shafts 43 are symmetrically arranged on both sides of the interior of the foaming pool 1 .

[0036] Working principle: Place the large-sized workpiece to be cleaned on the placement table 7 in the foaming pool 1 to ensure that the workpiece is stable and easy to clean. The internal space of the foaming pool 1 is sufficient to accommodate the large-sized workpiece, and the cleaning liquid fully covers the surface of the workpiece. The capacitive sensor 10 indirectly determines the water level by measuring the capacitance change between the two electrodes. When the water level rises or falls, it will affect the electric field around the sensor, thereby changing the capacitance value to determine the water level. Then start the water suction pump 61, and the cleaning liquid is injected into the foaming pool 1 from the external water source through the water inlet pipe 62 through the water suction pump 61. The water inlet pipe 62 fits tightly with the inner surface of the foaming pool 1 to prevent leakage of the cleaning liquid. After the cleaning liquid is injected, the ultrasonic transducer 2 starts to work and converts electrical energy into high-frequency sound waves. These sound waves form tiny bubbles in the cleaning liquid, which expand and burst rapidly under the action of the sound waves, generating gentle pressure pulses. These pulses can penetrate the tiny gaps on the surface of the workpiece and effectively remove stains and attachments. At the same time, the Roots blower 31 above the fixed plate 34 is started, and the Roots blower 31 supplies air to the butterfly aerator 33 through the air inlet pipe 32. The butterfly aerator 33 generates bubbles inside the foaming pool 1, increases the air intake, and promotes the oxygen content in the cleaning liquid. At the same time, the stirring action of the bubbles helps the cleaning liquid to be evenly distributed on the surface of the workpiece. In order to disrupt the directional flow effect of the internal solution, the DC motor 42 can be started through the control end, and the DC motor 42 drives the corrosion-resistant shaft 43 and the stirring rod 44 to rotate. The stirring rod 44 stirs the cleaning liquid inside the foaming pool 1, further promoting the uniform distribution and rapid movement of bubbles in the liquid, ensuring that the cleaning liquid can fully contact the surface of the workpiece and improve the cleaning efficiency. During the cleaning process, some stains and waste are brought to the top of the foaming pool 1 by the bubbles. At this time, the push cylinder 52 drives the metal telescopic tube 54 and the suction head 57 to move up and down through the push rod 53 and the clamping plate 55, and the suction head 57 absorbs and collects the waste. The waste is then discharged through the waste pipe 56, and the sewage pump 8 extracts the waste water, which is filtered through the slag collection frame 9 to separate the solid waste and liquid waste water. The waste and liquid waste water are put into the slag collection frame 9 along the bottom of the waste pipe 56 to prevent them from entering the drainage system and causing environmental pollution. After the cleaning is completed, the drainage pump 63 discharges the cleaning liquid in the foaming pool 1 through the slag pipe 64 to prepare for the next cleaning. At the same time, the design of the slag pipe 64 also ensures that the solid waste in the cleaning liquid can be effectively separated to prevent clogging of the drainage system. The entire cleaning process can be circulated until the workpiece reaches the expected cleanliness.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
