It should be noted that, when the purified water tank 21 supplies the purified water to the water using mechanism 10 through the first conveying pipe 51, the cleaning liquid is the purified water; when the lye tank 22 delivers the lye to the water using mechanism 10 through the second delivery pipe 52, the cleaning solution is lye; when the water for injection tank 23 supplies the water for injection to the water using mechanism 10 through the third supply line 53, the cleaning liquid is the water for injection.

In the CIP cleaning system, during operation, after the purified water is output to the water using mechanism 10 through the first conveying pipeline 51 by the purified water tank 21, the purified water is output by the water using mechanism 10 to clean the target cleaning object, the backwater after the target cleaning object is cleaned is collected by the backwater mechanism 30, the conductivity of the backwater is detected by the first conductivity detector, when the conductivity of the backwater does not meet the requirement, it indicates that the backwater has poor quality and contains more impurities such as iron filings, silt and the like, the controller 40 correspondingly controls the backwater mechanism 30 to discharge the collected backwater through the drain pipe 71, when the conductivity of the backwater meets the requirement, it indicates that the backwater quality reaches the standard, and the controller 40 correspondingly controls the backwater mechanism 30 to output the collected backwater to the purified water tank 21 through the first backwater pipeline 61; similarly, after the alkali liquor is output to the water using mechanism 10 by the alkali liquor tank 22 through the second conveying pipeline 52, the alkali liquor is output and a target cleaning object is cleaned by the water using mechanism 10, the backwater after the target cleaning object is cleaned is collected by the backwater mechanism 30, the conductivity of the backwater is detected by the first conductivity detector, when the conductivity of the backwater does not meet the requirement, the controller 40 correspondingly controls the backwater mechanism 30 to discharge the collected backwater outwards through the drain pipe 71, when the conductivity of the backwater meets the requirement, the quality of the backwater is indicated to be up to standard, and the controller 40 correspondingly controls the backwater mechanism 30 to output the collected backwater to the alkali liquor tank 22 through the second backwater pipeline 62; after the injection water tank 23 outputs the injection water to the water using mechanism 10 through the third conveying pipeline 53, the water using mechanism 10 outputs the injection water and cleans a target cleaning object, the backwater mechanism 30 collects the backwater after cleaning the target cleaning object, the conductivity of the backwater is detected by the first conductivity detector, when the conductivity of the backwater does not meet the requirement, the controller 40 correspondingly controls the backwater mechanism 30 to discharge the collected backwater outwards through the drain pipe 71, when the conductivity of the backwater meets the requirement, the quality of the backwater is indicated to reach the standard, and the controller 40 correspondingly controls the backwater mechanism 30 to output the collected backwater to the injection water tank 23 through the third backwater pipeline 63. Therefore, the backwater mechanism 30 can return the backwater with the conductivity meeting the requirement to the purification water tank 21, the lye tank 22 or the injection water tank 23, but not all the backwater is discharged outwards as sewage, so that water resources can be greatly saved, and the cost is reduced.

Referring to fig. 1, in one embodiment, the water using mechanism 10 includes a water using main pipe 11 and at least two water using pipes 12 respectively communicating with the water using main pipe 11. The water main 11 is connected to a first feed line 51, a second feed line 52, and a third feed line 53, respectively. The water using pipe 12 is connected to the water using point 13, and the water using pipe 12 is provided with a first switch valve 121. Like this, can send the washing liquid respectively to at least two water consumption points 13 through at least two branch pipes 12 to under the control of first ooff valve 121, can realize that at least two water consumption points 13 use water in step or use water in proper order, can be according to the nimble water use of actual demand.

Referring to fig. 1, in one embodiment, the water return mechanism 30 includes a first water return main pipe 31 and at least two water return branch pipes 32 respectively connected to the first water return main pipe 31. The first return water manifold 31 is connected to a first return water line 61, a second return water line 62, and a third return water line 63, respectively. The return water branch pipe 32 is used for connecting with a return water point 33, and a second switch valve 321 is arranged on the return water branch pipe 32. So, can receive the return water of two at least return water points 33 respectively through two at least return water branch pipes 32 to under the control of second ooff valve 321, can realize two at least return water points 33 synchronous return water or return water in proper order, can be according to the nimble return water of actual demand. Specifically, the number of the water return points 33 is not less than the number of the water consumption points 13, and each water consumption point 13 corresponds to a water return point 33, that is, the return water generated at the water consumption point 13 enters the corresponding water return point 33 and is collected at the corresponding water return point 33 through the return water branch pipe 32.

Referring to fig. 1, in one embodiment, the CIP cleaning system further includes a delivery manifold 54. The first delivery pipe 51, the second delivery pipe 52 and the third delivery pipe 53 are all connected with the water consuming mechanism 10 through a delivery manifold 54. The delivery manifold 54 is provided with a first water pump 541. A third on/off valve 55 is provided on each of the first delivery pipe 51, the second delivery pipe 52, and the third delivery pipe 53. Therefore, on one hand, the first conveying pipeline 51, the second conveying pipeline 52 and the third conveying pipeline 53 are connected with the water using mechanism 10 through the conveying header pipe 54, so that the first conveying pipeline 51, the second conveying pipeline 52 and the third conveying pipeline 53 do not need to be directly connected with the water using mechanism 10, the pipeline structure can be simplified, and the cost can be saved; on the other hand, the first water pump 541 may be provided in the delivery manifold 54, and the cleaning liquid in the purified water tank 21, the alkaline solution tank 22 or the injection water tank 23 may be delivered to the water using mechanism 10 by the power of the first water pump 541 and the engagement of the third on/off valve 55 on the corresponding pipe.

Referring again to fig. 1, in one embodiment, the CIP cleaning system further includes a second conductivity detector 56 and a first control valve 57. The second conductivity detector 56 is disposed on the delivery manifold 54, the delivery manifold 54 is further communicated with the sewage pipe 71 through the first connection pipe 58, and the first control valve 57 is used for controlling the delivery manifold 54 to be communicated with the first connection pipe 58 or the water using mechanism 10. Specifically, the second conductivity detector 56 and the first control valve 57 are electrically connected to the controller 40. Thus, when the second conductivity detector 56 detects that the conductivity of the cleaning liquid conveyed by the conveying main pipe 54 is not satisfactory, the controller 40 controls the first control valve 57 to operate, so that the conveying main pipe 54 is communicated with the first connecting pipe 58, and at the moment, the conveying main pipe 54 is disconnected from the water using mechanism 10, so that the conveying main pipe 54 directly conveys the cleaning liquid with the unsatisfactory conductivity to the sewage discharge pipe 71 through the first connecting pipe 58, and the cleaning liquid is timely discharged outwards through the sewage discharge pipe 71, so that the cleaning liquid with the unsatisfactory conductivity can be prevented from entering the water using mechanism 10; when the second conductivity detector 56 detects that the conductivity of the cleaning solution delivered to the delivery manifold 54 is satisfactory, the controller 40 controls the first control valve 57 to operate, so that the delivery manifold 54 is connected to the water using mechanism 10, and the delivery manifold 54 is disconnected from the first connection pipe 58, so that the delivery manifold 54 can deliver the cleaning solution with satisfactory conductivity to the water using mechanism 10.

The first control valve 57 may be, for example, two electric control valves respectively provided in the first connection pipe 58 and the water using mechanism 10, or may be a multi-way control valve such as a three-way control valve or a four-way control valve, as long as the cleaning liquid can be selectively delivered to the water using mechanism 10 by the delivery main pipe 54 or delivered to the sewage pipe 71 through the first connection pipe 58.

It should be noted that the first connecting pipe 58 can be directly connected to the sewage pipe 71, or indirectly connected to the sewage pipe 71, and can be flexibly adjusted and set according to actual requirements.

Referring again to fig. 1, in one embodiment, the CIP cleaning system further includes a heat exchanger 81. The heat exchanger 81 is provided with a first heat exchange pipeline and a second heat exchange pipeline. The first heat exchange pipeline is matched with the second heat exchange pipeline. The first heat exchange line is used for being arranged on the conveying header pipe 54 in series, and the second heat exchange line is used for introducing a heat medium. Therefore, when the cleaning liquid flows through the first heat exchange pipeline, the cleaning liquid exchanges heat with the heat medium flowing in the second heat exchange pipeline, the temperature of the cleaning liquid can be correspondingly increased, and the temperature of the cleaning liquid is heated to a preset temperature (including but not limited to 80 ℃), so that the cleaning effect on a target cleaning object when the cleaning liquid enters the water using mechanism 10 can be ensured.

It should be noted that the heat medium includes, but is not limited to, steam, specifically, industrial steam; in addition, the heat medium can also be high-temperature hot water and the like, and can be flexibly set and adjusted according to actual requirements.

Referring again to fig. 1, in one embodiment, the CIP cleaning system further includes a first condensate drain pipe 72. The air inlet part of the second heat exchange pipeline is connected with a steam inlet pipe 82, the steam inlet pipe 82 is used for being communicated with an industrial steam source 83, and a fourth switch valve 821 and a proportion adjusting valve 822 are arranged on the steam inlet pipe 82. The air outlet of the second heat exchange pipeline is connected with a first drain pipe 84, the first drain pipe 84 is communicated with the first condensed water outlet pipe 72, and a first drain valve 841 and a fifth switch valve 842 are arranged on the first drain pipe 84. Therefore, on one hand, the industrial steam source 83 can provide high-temperature steam, the high-temperature steam of the industrial steam source 83 is reasonably utilized, and the effect of saving energy is achieved; on the other hand, when the industrial steam source 83 is required to be used, the fourth switch valve 821 is opened, and when the industrial steam source 83 is not required to be used, the fourth switch is closed; in addition, after the high-temperature steam enters the second heat exchange pipeline for heat exchange and temperature reduction, the generated condensed water is discharged outwards through the first water discharge pipe 84, and the first water discharge pipe 84 discharges the condensed water into the first condensed water external discharge pipe 72; in addition, the first trap 841 can convert the steam entering the first drain pipe 84 into condensed water and discharge the condensed water to the outside.

Referring again to FIG. 1, in one embodiment, there are two fifth switch valves 842, one of which 842 is disposed upstream of first trap 841 and the other of which 842 is disposed downstream of first trap 841. The first drain pipe 84 is connected in parallel to a backup pipe 85, and the backup pipe 85 is provided with a sixth on-off valve 851. Thus, when the first drain valve 841 is damaged, the first drain valve 841 can be maintained and replaced in time by closing the two fifth switch valves 842; in addition, the sixth on-off valve 851 on the backup pipe 85 may be opened to discharge the condensed water to the first condensed water drain pipe 72 through the backup pipe 85, thereby ensuring that the CIP cleaning system is not operated at a standstill.

It should be noted that the upstream position of the first trap 841 refers to the water inlet side of the first trap 841, that is, one of the fifth switch valves 842 and the trap are sequentially disposed on the first drain pipe 84 along the water flow direction; conversely, the downstream position of the first trap 841 means that the first trap 841 is on the water outlet side, i.e., the trap and the other fifth on-off valve 842 are arranged on the first drain pipe 84 in the water flow direction in sequence.

Referring again to fig. 1, in one embodiment, a second drain 591 is also connected to the delivery manifold 54. The second water discharge pipe 591 is disposed at an upstream position of the first water pump 541, and the second water discharge pipe 591 is communicated with the drain pipe 71. Specifically, the CIP cleaning system further includes a second control valve 592, the second control valve 592 being used to control whether the delivery manifold 54 is in communication with the second drain 591. In this way, when any one of the purified water tank 21, the lye tank 22 and the injection water tank 23 needs to be drained of the cleaning solution therein during the sterilization process, the second control valve 592 is actuated to connect the delivery manifold 54 with the second water drain pipe 591, so as to directly drain the cleaning solution into the sewage pipe 71 through the second water drain pipe 591 without being pumped back into the water consuming mechanism 10 or the first connecting pipe 58 by the first water pump 541.

It should be noted that the water returning mechanism 30 may be directly communicated with the first water returning pipeline 61, the second water returning pipeline 62, the third water returning pipeline 63 and the sewage draining pipe 71, or indirectly communicated with the first water returning pipeline 61, the second water returning pipeline 62, the third water returning pipeline 63 and the sewage draining pipe 71, and the specific communication mode may be flexibly adjusted and set according to actual requirements. In this embodiment, the example will be described specifically in which the water returning mechanism 30 is indirectly communicated with the first water returning pipeline 61, the second water returning pipeline 62, the third water returning pipeline 63 and the sewage draining pipe 71 respectively.

Referring to fig. 1, in one embodiment, the CIP cleaning system further includes a second water return manifold 64. The first water return pipeline 61, the second water return pipeline 62 and the third water return pipeline 63 are all connected with the water return mechanism 30 through a second water return manifold 64. The first water return pipeline 61, the second water return pipeline 62 and the third water return pipeline 63 are all provided with seventh switching valves 65. Therefore, on one hand, the first water return pipeline 61, the second water return pipeline 62 and the third water return pipeline 63 are connected with the water return mechanism 30 through the second water return header pipe 64, so that the first water return pipeline 61, the second water return pipeline 62 and the third water return pipeline 63 do not need to be directly connected with the water return mechanism 30, the pipeline structure can be simplified, and the cost can be saved; on the other hand, the seventh on-off valve 65 on the corresponding pipeline is controlled to open and close, so that purified water, alkali liquor or water for injection are respectively conveyed into the corresponding tank.

Referring to fig. 1, in one embodiment, the water return mechanism 30 is connected to the second water return manifold 64 through the first water return manifold 31, and the first water return manifold 31 is further connected to the sewage pipe 71 through the third water discharge pipe 66. Specifically, the CIP cleaning system further comprises a third control valve 67. The third control valve 67 is used to control the first water return manifold 31 to communicate with the second water return manifold 64 or the third water discharge pipe 66. The third control valve 67 is electrically connected to the controller 40. The controller 40 controls the first return water manifold 31 to communicate with the second return water manifold 64 or the third drain pipe 66 according to the detection result of the conductivity of the return water. When the detection result of the conductivity of the return water meets the requirement, the first return water main pipe 31 is communicated with the second return water main pipe 64; when the detection result of the conductivity of the return water is not satisfactory, the first return water main pipe 31 is communicated with the third drain pipe 66, so that the return water with the detection result of the conductivity which is not satisfactory can be timely discharged to the outside through the third drain pipe 66 and the sewage discharge pipe 71.

It should be noted that, in an embodiment, each of the first switch valve 121 to the seventh switch valve 65 may be an electric control valve, and the electric control valves are electrically connected to the controller 40 and operate under the control of the controller 40, so that the degree of automation can be improved without manual operation. Of course, the first to seventh on-off valves 121 to 65 may also be respectively configured as manual valves, which are not limited herein and are flexibly adjusted and configured according to actual requirements.
