Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.

[0027] The present utility model provides as Figures 1-4An efficient chemical cleaning device shown in the figure includes a base 15 and a plurality of medicine preparation boxes 10 installed on the base 15;

[0028] A finished product medicine pump 4 is provided at the rear side of each of the plurality of medicine preparation boxes 10;

[0029] An inlet liquid pipeline 14 is provided between the front outer walls of the plurality of medicine preparation boxes 10 to convey liquid into the medicine preparation boxes 10;

[0030] Folding covers 7 are drivingly connected to the upper outer walls of the plurality of medicine preparation boxes 10 to add the required agents into the medicine preparation boxes 10. A plurality of dissolved air release heads 8 are equidistantly arranged on the lower outer walls of the plurality of medicine preparation boxes 10 to release gas into the medicine preparation boxes 10. A box partition 13 is fixedly connected inside each of the plurality of medicine preparation boxes 10 to separate a medicine preparation chamber and a finished product chamber. During operation, the original liquid or water is conveyed into the medicine preparation chamber on the right side of the medicine preparation box 10 through the inlet liquid pipeline 14. After the water level reaches a certain height, on-site operators add appropriate agents according to the actual working conditions by opening the folding cover 7. After adding the agents, compressed air is input into the medicine preparation box 10 through the dissolved air release heads 8 to form an aeration function, accelerating the dissolution and preparation efficiency of the agents. As the agents and water are continuously added, when the agents prepared in the medicine preparation chamber inside the medicine preparation box 10 reach the height of the opening of the box partition 13, they overflow into the finished product chamber on the left side of the medicine preparation box 10. The finished product chamber can also perform aeration operation through the dissolved air release heads 8 to prevent the finished product agents in the finished product chamber from solidifying or precipitating before being discharged from the box. The agents in the finished product chamber are conveyed outward through the finished product medicine pump 4 to the device to be cleaned for cleaning;

[0031] Air bags 20 are provided inside the plurality of medicine preparation boxes 10 and are respectively close to the left and right sides. A defoaming net b22 is provided close to the upper side between the two air bags 20. An anti-foaming net a18 is provided above the defoaming net b22 to eliminate the bubbles and foam on the liquid surface in the medicine preparation box 10. When mixing agents in the medicine preparation box 10, the gas discharged by the dissolved air release heads 8 drives the agent particle powders to float upward. The foam and bubbles floating on the liquid surface can be eliminated through the anti-foaming net a18 and the defoaming net b22, and the air bags 20 support the anti-foaming net a18 and the defoaming net b22 to move synchronously with the liquid level height for defoaming operation.

[0032] Such as Figure 3 and Figure 4As shown, fixed shells 21 are sleeved on the outer sides of multiple air bags 20 to cover the air bags 20. A fixed frame 19 is fixedly connected between the upper outer walls of the two fixed shells 21 to limit the positions of the defoaming net a18 and the defoaming net b22. Limiting blocks 17 are fixedly connected to the inner walls at the left and right ends of multiple medicine dispensing boxes 10 and the outer walls at the left and right ends of the box partition 13 near the upper side to limit the maximum upward floating distance of the fixed frame 19. The mesh density of the defoaming net a18 is smaller than that of the defoaming net b22.

[0033] The position of the air bag 20 is restricted by the fixed shell 21, and the air bag 20 is shielded and protected to prevent the air bag 20 from being damaged. At the same time, the positions of the defoaming net a18 and the defoaming net b22 are restricted by the fixed frame 19. When the air bag 20 provides an upward buoyancy force, the fixed frame 19, the defoaming net a18, and the defoaming net b22 can be driven to float synchronously. At the same time, the maximum upward floating position of the fixed frame 19 is restricted by the limiting block 17 to prevent the situation where the fixed frames 19 on the left and right sides cannot completely cover the liquid surface.

[0034] As Figure 5 shown, the fixed frame 19, the defoaming net a18, and the defoaming net b22 are all made of hollow plastic materials, and hydrogen is filled inside multiple air bags 20.

[0035] The fixed frame 19, the defoaming net a18, and the defoaming net b22 made of hollow plastic can reduce their own weights when receiving the upward buoyancy force provided by the hydrogen-filled air bag 20, so that the air bag 20 can stably lift the fixed frame 19, the defoaming net a18, and the defoaming net b22 to float.

[0036] As Figure 1 and Figure 2 shown, one end of each of multiple dissolved air release heads 8 is fixedly connected to a dissolved air pipeline 11, one end of each of multiple dissolved air pipelines 11 is fixedly connected to a dissolved air inlet box pipeline 9, and an intake main pipeline 1 is fixedly connected between multiple dissolved air inlet box pipelines 9 to guide gas to the dissolved air release heads 8. Intake valves 5 are arranged on the left sides of multiple finished medicine pumps 4 to guide the gas in the intake main pipeline 1 into the finished medicine pumps 4 to complete the external delivery of the medicine.

[0037] Compressed gas is transported through the intake main pipeline 1 and is transported to the dissolved air release heads 8 through the dissolved air inlet box pipelines 9 and the dissolved air pipelines 11 to achieve the effect of continuous gas transportation and aeration. By opening and closing the intake valve 5, compressed air can be transported through the intake main pipeline 1 into the finished medicine pumps 4 to complete the external delivery of the medicine.

[0038] As Figure 1 and Figure 2As shown in the figure, the outer walls of the right ends of multiple finished medicine pumps 4 are all provided with liquid outlet pipelines a2. The other ends of the multiple liquid outlet pipelines a2 are fixedly connected with liquid outlet pipelines b3 respectively to convey the finished medicine to the device to be cleaned outside. The outer walls of the fronts of the multiple dispensing boxes 10 are respectively provided with a plurality of air vent a12 and air vent b16 near the lower left corner and the right end outer wall to discharge the remaining medicine outward. The sizes of the multiple air vent a12 and air vent b16 are the same.

[0039] Through the liquid outlet pipeline a2 and the liquid outlet pipeline b3, the finished medicine can be externally conveyed to the corresponding device to be cleaned under the push of the finished medicine pump 4, and the medicine that has not been completely used can be discharged outward through the air vent a12 and the air vent b16.

[0040] As Figure 1 、 Figure 2 and Figure 3 shown in the figure, through holes penetrating left and right are respectively opened near the upper sides inside the left end outer walls of the multiple box partitions 13 to guide the medicine in the right dispensing chamber to the finished product chamber. Aeration pumps connected to the dissolved air release heads 8 are respectively arranged on the lower inner walls of the multiple dispensing boxes 10 near the left and right sides. A plurality of casters 23 are equidistantly fixedly connected to the lower outer walls of the multiple bases 15. Drainage pipelines 6 are fixedly connected between the multiple air inlet valves 5 and the dispensing boxes 10.

[0041] When the medicine in the dispensing chamber reaches one side of the through hole opened on the box partition 13, the medicine can overflow into the left finished product chamber. The compressed air discharged from the dissolved air release head 8 diffuses outward through the aeration pump. The whole can be moved synchronously through the plurality of casters 23. The medicine in the dispensing box 10 can be guided into the finished medicine pump 4 through the drainage pipeline 6.

[0042] The implementation principle of this embodiment is as follows: During operation, the stock solution or water is transported through the liquid inlet pipeline 14 to the chemical dosing bin on the right side of the chemical dosing box 10. After the water level reaches a certain height, the on-site operator adds appropriate chemicals according to the actual working conditions by opening the folding cover plate 7. After adding the chemicals, compressed air is input into the interior of the chemical dosing box 10 through the dissolved air release head 8 to form an aeration function, which accelerates the dissolution and preparation efficiency of the chemicals. As the chemicals and water are continuously added, when the chemicals prepared in the chemical dosing chamber inside the chemical dosing box 10 reach the height of the opening of the box partition 13, they overflow into the finished product bin on the left side of the chemical dosing box 10. The dissolved air release head 8 can also perform aeration operation in the finished product bin to prevent the finished chemicals in the finished product bin from solidifying or precipitating before being discharged from the box. The chemicals in the finished product bin are transported outward through the finished product chemical pump 4 to the device to be cleaned for cleaning. When mixing the chemicals in the chemical dosing box 10, when the gas discharged from the dissolved air release head 8 drives the chemical particle powder to float, the foam and bubbles floating on the liquid surface can be eliminated through the defoaming net a18 and the defoaming net b22, and the defoaming net a18 and the defoaming net b22 are lifted by the airbag 20 to move synchronously with the liquid surface height for defoaming operation.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
