[0002] Conductivity is a digital representation of the ability of a solution to conduct electric current. The conductivity of a solution has a certain relationship with the amount of inorganic acid, alkali and salt it contains. When the concentration of the inorganic acid, alkali and salt in the solution changes, the conductivity of the solution increases with the increase in concentration. Therefore, the conductivity of a solution is often used to infer the total concentration of ions or salt content in the solution.

[0003] In the related art, a CIP (Clean In Place) cleaning device includes a cleaning tank, a cleaning pipeline and a return pipeline. The cleaning tank is used to store the cleaning solution. The cleaning tank transports the cleaning solution to the inner cavity of the cleaning object through the cleaning pipeline for cleaning. The return pipeline connects the sewage outlet of the cleaning object and the return inlet of the cleaning tank. By installing a conductivity meter on the return pipeline of the CIP cleaning device, the conductivity meter is used to monitor the conductivity of the solution in the return pipeline to confirm the cleaning intensity of the CIP cleaning device and judge the switching point of the cleaning agent and water.

[0004] However, during the operation of the CIP cleaning device, due to the effects of dirt, mechanical force, cavitation, etc., the return liquid in the return pipe will contain a large number of bubbles, making the detection results of the conductivity meter inaccurate. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a cleaning device, which includes a cleaning tank 10, a reflux pipeline 20 and a conductivity detection component 30. The cleaning tank 10 has a liquid outlet 11 and a reflux port 12. The reflux pipeline 20 includes a liquid inlet pipe 21, a liquid outlet pipe 22 and a detection pipe 23. The detection pipe 23 includes a bubble branch pipe 231 and a detection branch pipe 232 extending in the transverse direction. The detection branch pipe 232 is located below the bubble branch pipe 231. The inlet of the bubble branch pipe 231 and the inlet of the detection branch pipe 232 are both connected to the outlet of the liquid inlet pipe 21, the outlet of the bubble branch pipe 231 and the outlet of the detection branch pipe 232 are both connected to the inlet of the liquid outlet pipe 22, the outlet of the liquid outlet pipe 22 is connected to the reflux port 12, and the conductivity detection component 30 is arranged on the detection branch pipe 232.

[0027] By using the cleaning device provided in this embodiment, the cleaning tank 10 transports the cleaning solution to the inner cavity of the cleaning object 40 through the liquid outlet 11 and the cleaning port 41 of the cleaning object 40 for cleaning. The reflux pipeline 20 connects the sewage outlet 42 of the cleaning object 40 and the reflux port 12 of the cleaning tank 10. The cleaning solution after cleaning enters the liquid inlet pipe 21. During the operation of the cleaning device, due to the effects of dirt, mechanical force, cavitation, etc., the cleaning solution entering the liquid inlet pipe 21 contains a large amount of bubbles. Since the bubble branch pipe 231 and the detection branch pipe 232 both extend in the horizontal direction, and the detection branch pipe 232 is located below the bubble branch pipe 231, the inlet of the bubble branch pipe 231 and the inlet of the detection branch pipe 232 are both connected to the The outlet of the liquid inlet pipe 21 is connected, and under the action of gravity of the cleaning solution, most of the gas and foam in the cleaning solution in the liquid inlet pipe 21 enter the bubble branch pipe 231 and flow into the liquid outlet pipe 22 through the bubble branch pipe 231, and the remaining cleaning solution in the liquid inlet pipe 21 enters the detection branch pipe 232 and flows into the liquid outlet pipe 22 through the detection branch pipe 232, so as to increase the stability of the cleaning solution in the detection branch pipe 232, avoid the gas and foam in the cleaning solution affecting the coverage of the liquid component in the cleaning solution on the conductivity detection element 30, avoid the gas and foam in the cleaning solution causing the conductivity curve detected by the conductivity detection element 30 to fluctuate, and improve the detection stability and detection accuracy of the conductivity detection element 30.

[0028] The cleaning tank 10 may be an acid cleaning tank or an alkaline cleaning tank.

[0029] like Figure 2 As shown, the diameter of the bubble branch tube 231 is smaller than the diameter of the liquid inlet tube 21. When the cleaning solution in the liquid inlet tube 21 flows out of the liquid inlet tube 21, the resistance of the cleaning solution entering the bubble branch tube 231 is increased. Under the action of gravity of the cleaning solution, the liquid components in the cleaning solution are facilitated to enter the detection branch tube 232.

[0030] like Figure 2As shown, the bubble branch pipe 231 includes a tapered pipe 2311 and a straight pipe 2312, the outlet of the liquid inlet pipe 21 is connected to the inlet of the tapered pipe 2311, the outlet of the tapered pipe 2311 is connected to the inlet of the straight pipe 2312, the outlet of the straight pipe 2312 is connected to the inlet of the liquid outlet pipe 22, and the diameter of the tapered pipe 2311 gradually decreases in the direction pointing to the straight pipe 2312. In the process of the cleaning solution in the bubble branch pipe 231 passing through the tapered pipe 2311 and entering the straight pipe 2312, the flow rate of the cleaning solution in the bubble branch pipe 231 increases to defoam the cleaning solution.

[0031] like Figure 2 As shown, the bubble branch pipe 231 further includes a tapered pipe 2313, the outlet of the straight pipe 2312 is connected to the inlet of the tapered pipe 2313, the outlet of the tapered pipe 2313 is connected to the inlet of the liquid outlet pipe 22, and the diameter of the tapered pipe 2313 gradually decreases in the direction pointing to the straight pipe 2312. In the process of the cleaning solution in the bubble branch pipe 231 passing through the straight pipe 2312 and entering the tapered pipe 2313, the pressure of the cleaning solution in the bubble branch pipe 231 increases, so as to defoam the cleaning solution again.

[0032] like Figure 2 As shown, the diameter of the bubble branch tube 231 is smaller than the diameter of the detection branch tube 232. When the cleaning solution in the liquid inlet tube 21 flows out of the liquid inlet tube 21, the resistance of the cleaning solution entering the bubble branch tube 231 is reduced compared to the bubble branch tube 231. Under the action of gravity of the cleaning solution, the liquid component in the cleaning solution is facilitated to enter the detection branch tube 232.

[0033] like Figure 2 As shown, the detection branch pipe 232 includes a first vertical pipe 2321, a detection transverse pipe 2322 and a second vertical pipe 2323. The upper end of the first vertical pipe 2321 is connected to the outlet of the liquid inlet pipe 21. The detection transverse pipe 2322 is arranged in parallel below the bubble branch pipe 231. The inlet of the detection transverse pipe 2322 is connected to the lower end of the first vertical pipe 2321. The outlet of the detection transverse pipe 2322 is connected to the lower end of the second vertical pipe 2323. The upper end of the second vertical pipe 2323 is connected to the inlet of the liquid outlet pipe 22. The above structure is adopted to facilitate the liquid component in the cleaning solution to enter the detection transverse pipe 2322 and improve the flow stability of the cleaning solution in the detection transverse pipe 2322.

[0034] like Figure 1 and Figure 2 As shown, the conductivity detection element 30 is arranged on the detection transverse tube 2322. Since the cleaning solution in the detection transverse tube 2322 is relatively stable, the detection stability and detection accuracy of the conductivity detection element 30 can be improved.

[0035] like Figure 2As shown, the liquid inlet pipe 21, the liquid outlet pipe 22 and the bubble branch pipe 231 are coaxially arranged to reduce the resistance of the foam component of the cleaning solution passing through the liquid inlet pipe 21, the liquid outlet pipe 22 and the bubble branch pipe 231, so that the foam component of the cleaning solution can smoothly pass through the liquid inlet pipe 21, the liquid outlet pipe 22 and the bubble branch pipe 231.

[0036] like Figure 1 As shown, the return line 20 also includes a flow detection member 24 disposed on the liquid inlet pipe 21. The flow detection member 24 is used to detect the flow of the cleaning solution in the liquid inlet pipe 21 to prevent the cleaning solution flow in the liquid inlet pipe 21 from being too low and affecting the detection result of the conductivity detection member.

[0037] In this embodiment, the reflux pipeline 20 further includes a control component and an alarm, the control component is respectively connected to the flow detection component 24 and the alarm signal, and the control component controls the alarm to work according to the detection result of the flow detection component 24. When the detection result of the flow detection component 24 is lower than the set value, the control component sends an alarm signal to the alarm.

[0038] like Figure 1 As shown, the reflux pipeline 20 also includes a reflux valve 25 and a reflux pump 26 disposed on the liquid inlet pipe 21. The reflux valve 25 is used to control the opening and closing of the liquid inlet pipe 21, and the reflux pump 26 is used to increase the flow power of the cleaning solution.

[0039] like Figure 1 As shown, the reflux pipeline 20 further includes a filter 27 disposed on the liquid inlet pipe 21. The filter 27 is used to filter the cleaning solution after cleaning.
