Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to an environmentally friendly cleaning agent circulation system for cleaning machines. Background Technology

[0002] Cleaning machines are widely used in industrial production and daily life for cleaning various items. As an important component of cleaning machines, cleaning agents are of great concern in terms of their usage cost and environmental performance. Adding cleaning agents to cleaning machines can improve the cleaning effect on the items being cleaned.

[0003] Currently, in traditional cleaning machines, the cleaning agent is often used only once and is discharged directly after each use. This not only causes a lot of waste of resources and increases cleaning costs, but also causes serious environmental pollution if the waste cleaning agent is not disposed of properly.

[0004] While some existing cleaning agent recycling systems achieve a degree of cleaning agent reuse, they suffer from several drawbacks. For example, some systems have poor filtration, failing to effectively remove impurities and contaminants from the cleaning agent, leading to a decrease in the cleaning capacity of the recycled agent and affecting the cleaning effect. Therefore, we propose an environmentally friendly cleaning agent recycling system for cleaning machines. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly cleaning agent circulation system for cleaning machines, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-3 This utility model provides a technical solution: an environmentally friendly cleaning agent circulation system for a cleaning machine, including a storage tank 1. A suction pipe 121 is fixedly installed on the bottom of the storage tank 1. A delivery pump 12 is fixedly installed at the end of the suction pipe 121. A delivery pipe 122 is fixedly installed at the outlet end of the delivery pump 12. The delivery pipe 122 is connected to the liquid inlet pipe of the cleaning machine. A filter element 3 for filtering the environmentally friendly cleaning agent is provided inside the storage tank 1. A flexible hose 21 is detachably installed at the liquid inlet end of the filter element 3. The end of the flexible hose 21... A detachable return pipe 2 is installed, and a second valve 20 is installed between the return pipe 2 and the hose 21. The return pipe 2 is connected to the liquid outlet pipe of the cleaning machine, forming a complete circulation path. The delivery pump 12 delivers the environmentally friendly cleaning agent in the storage tank 1 to the cleaning machine through the suction pipe 121 and the delivery pipe 122. After use, the cleaning agent enters the filter element 3 through the return pipe 2, the second valve 20, and the hose 21 and is then returned to the storage tank 1 for filtration, so that the cleaning agent can be recycled, avoiding the waste and pollution caused by one-time discharge and reducing the cost of use.

[0033] like Figure 1 As shown, multiple support legs 10 are fixedly installed at the bottom of the storage box 1. The height of the support legs 10 is between 5cm and 12cm, and the support legs 10 make the storage box 1 stable.

[0034] like Figure 1 As shown, a discharge pipe 11 is fixedly installed on the bottom side of the storage box 1, and a first valve 111 is fixedly installed on the discharge pipe 11 so that sewage can be conveniently discharged through the discharge pipe 11 in the future.

[0035] like Figure 1 As shown, an exhaust pipe 13 is fixedly installed on the top of the storage box 1, and an exhaust valve 131 is fixedly installed on the exhaust pipe 13 so that the exhaust pipe 13 can discharge the gas inside the box in a timely manner, so that the air pressure inside and outside the storage box 1 is consistent.

[0036] like Figure 1 As shown, an addition tube 14 is fixedly installed on the top of the storage box 1. A threaded cap 141 is threaded onto the addition tube 14. By unscrewing the threaded cap 141, cleaning agent can be easily added through the addition tube 14, making the system operation more convenient and ensuring stable operation.

[0037] like Figure 2 As shown, the top plate of the storage box 1 is provided with a plug hole 15, and the filter element 3 is plugged into the plug hole 15 to facilitate the installation and removal of the filter element 3.

[0038] In this embodiment, the filter element 3 includes a mesh support cylinder 30 disposed on the outermost layer. The mesh support cylinder 30 has a mesh-shaped cylindrical structure for the normal flow of cleaning agent. An ultrafiltration membrane 32 is fixedly installed on the inner wall of the mesh support cylinder 30. An activated carbon adsorption layer 33 is disposed on the inner side of the ultrafiltration membrane 32. A filter screen 34 is disposed on the inner side of the activated carbon adsorption layer 33. The filter screen 34 filters impurities, and the activated carbon adsorption layer 33 removes odors, thereby improving the filtration effect and achieving the effect of reusing the cleaning agent after filtration.

[0039] Specifically, a limiting ring 31 is fixedly installed at the top of the mesh support cylinder 30, and a flange 22 is fixedly installed at the bottom of the hose 21. The flange 22 and the limiting ring 31 are detachably connected to the top plate of the storage box 1 by multiple fastening screws. Sealing rings are provided between the flange 22 and the limiting ring 31, and between the limiting ring 31 and the top surface of the storage box 1, so that the filter element 3 is easy to install and remove, and the sealing rings can improve the sealing effect and prevent leakage.

[0040] It is worth noting that the ultrafiltration membrane 32 can be a hollow fiber ultrafiltration membrane. This type of membrane has the characteristics of large effective membrane area per unit volume and high filtration efficiency, which can well meet the needs of cleaning agent circulation filtration. Its pore size range is usually between 0.01 micrometers and 0.1 micrometers. Ultrafiltration membrane 32 with this pore size can effectively intercept tiny particulate impurities and colloidal substances generated in the cleaning agent during the cleaning process, preventing these pollutants from affecting the cleaning effect of the cleaning agent. At the same time, it can allow the effective components in the environmentally friendly cleaning agent to pass through smoothly, ensuring that the filtered cleaning agent still maintains good cleaning ability, thereby realizing the efficient recycling of the cleaning agent.

[0041] Finally, it should be noted that the delivery pump 12, the corresponding control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0042] When using the environmentally friendly cleaning agent circulation system for the cleaning machine of this utility model, unscrew the threaded cap 141 on the adding tube 14, add an appropriate amount of environmentally friendly cleaning agent into the storage box 1, and then tighten the threaded cap 141.

[0043] Start the delivery pump 12. The cleaning agent in the storage tank 1 enters the cleaning machine through the suction pipe 121, delivery pump 12, and delivery pipe 122. After cleaning is completed, open the second valve 20. The used cleaning agent enters the filter element 3 through the return pipe 2 and hose 21.

[0044] The cleaning agent first passes through filter screen 34 to filter out large particulate impurities, then through activated carbon adsorption layer 33 to remove odors, and finally passes through ultrafiltration membrane 32 before returning to storage tank 1 to complete the cycle.

[0045] When sewage needs to be discharged, open the first valve 111 and the impurities will be discharged through the discharge pipe 11. When replacing the filter element 3, remove the fastening screws, separate the flange 22 and the limit ring 31, and take the filter element 3 out from the insertion hole 15. The new filter element 3 can be installed in the reverse order.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
