DETAILED DESCRIPTION

[0037] The following will be described in detail below with reference to the accompanying drawings Figures 1-3 The present application is further described in detail.

[0038] EMBODIMENT

[0039] The embodiment of the present application discloses an automatic positioning CIP cleaning device for a filling valve. Referring to Figure 1 , mainly comprising a material cylinder 1, a liquid storage tank 2 and a circulating pump 3, a plurality of filling valves are installed on the material cylinder 1, the material cylinder 1 is communicated with a liquid inlet pipeline 11 and a center pipeline 12, the outlet end of the center pipeline 12 is communicated with a liquid outlet pipeline 13, the outlet end of the liquid outlet pipeline 13 is communicated with the liquid storage tank 2, a connecting pipeline is arranged between the liquid storage tank 2 and the circulating pump 3, the outlet end of the liquid inlet pipeline 11 is communicated with the material cylinder 1, a blowdown pipeline 15 is arranged on the liquid outlet pipeline 13, and a manual butterfly valve is installed on the blowdown pipeline 15; the center pipeline is communicated with a connecting pipeline 14, the liquid inlet end of the connecting pipeline 14 is detachably connected with a liquid injection head 4 of any filling valve; and the liquid storage tank 2 is fixedly installed with a cleaning detection module for detecting the cleaning effect.

[0040] When the filling valve needs to be cleaned, the operator can connect the connecting pipeline 14 to the filling valve that needs to be cleaned, and control the circulating pump 3 and the filling valve to start, the circulating pump 3 draws the cleaning liquid in the liquid storage tank 2 and sends it into the material cylinder 1 through the liquid inlet pipeline 11, the cleaning liquid in the material cylinder 1 flows back to the circulating pump 3 through the center pipeline 12, the liquid outlet pipeline 13, the liquid storage tank 2 and the connecting pipeline, and the cleaning liquid is circulated through the material cylinder 1 by the circulating pump 3; at the same time, the operator can start the filling valve, the cleaning liquid in the material cylinder 1 can flow to the center pipeline 12 through the filling valve, so that the cleaning liquid circulates in the material cylinder 1 and the filling valve at the same time, realizing the technical effect of automatically cleaning the material cylinder 1 and the filling valve, and avoiding the operation of manually removing the filling valve and cleaning the filling valve, thereby effectively improving the convenience of cleaning the filling valve. Through the setting of the cleaning detection module, the cleaning effect can be detected, and when the material cylinder 1 and the filling valve are cleaned, the operator can open the blowdown pipeline 15 through the manual butterfly valve, so that the cleaning liquid is discharged from the blowdown pipeline 15.

[0041] Referring to Figure 1 and Figure 2The liquid inlet end of the connecting pipeline 14 is fixedly installed with a connector 16, and a connecting groove hole 161 adapted to the liquid injection head 4 of the filling valve is formed in the connector 16. An outer thread is arranged on the outer side wall of the liquid injection head 4, and an inner thread is arranged on the inner side wall of the connecting groove hole 161. The connector 16 is threadedly connected to the liquid injection head 4.

[0042] The connector 16 on the connecting pipeline 14 can be connected to the liquid injection head 4 of the filling valve by thread connection, so that the cleaning liquid can flow into the connecting pipeline 14 after flowing out of the liquid injection head 4 in the subsequent cleaning process.

[0043] Referring to Figure 2 An elastic sealing ring 162 is fixedly connected to the inner side wall of the connecting groove hole 161 and located below the inner thread. A sealing ring groove 41 is formed in the outer side wall of the liquid injection head 4, and the elastic sealing ring 162 is embedded in the sealing ring groove 41.

[0044] The elastic sealing ring 162 is embedded in the sealing ring groove 41 on the liquid injection head 4, which can improve the sealing degree of the connection between the connector 16 and the liquid injection head 4 and reduce the flow of cleaning liquid from the connector 16.

[0045] Referring to Figure 3 The cleaning detection module comprises a flow monitoring unit installed on the liquid inlet pipeline 11, which is used to monitor the flow of cleaning liquid flowing through the cylinder 1 and output a detection trigger signal when the flow of cleaning liquid flowing through the cylinder 1 reaches a set value or an integer multiple of the set value; a water quality detector 5 fixedly installed on the liquid storage tank 2, which is signal connected with the signal output end of the flow monitoring unit, used to receive the detection trigger signal and detect the turbidity of the cleaning liquid in the liquid storage tank 2 and output an induced turbidity signal; and a prompt unit installed on the cleaning detection module, which is signal connected with the signal output end of the water quality detector 5, used to calculate the turbidity change value of the cleaning liquid and output a prompt signal when the turbidity of the cleaning liquid is stable.

[0046] Through the mutual matching and use of the flow monitoring unit, the water quality detector 5 and the prompt unit, the flow of cleaning liquid flowing through the liquid storage tank 2 can be monitored, and when the flow through the liquid storage tank 2 reaches a set value or an integer multiple of the set value, the water quality detection unit detects the water quality of the cleaning liquid in the liquid storage tank 2; when the turbidity of the cleaning liquid in the liquid storage tank 2 tends to be stable, the prompt unit outputs a prompt signal to prompt the completion of cleaning, so that the on-site operator can timely open the sewage pipeline 15 by a manual butterfly valve to discharge sewage.

[0047] It needs to be explained that in the embodiments of the present application, the water quality detector 5 is model InFit76X, which mainly detects the water quality of the cleaning liquid by detecting the turbidity of the cleaning liquid. In some other embodiments, according to the type of the material, the PH value of the cleaning liquid, etc., other sensors can be used for water quality detection, which is not limited and described here.

[0048] With reference to Figure 1 And Figure 3 The flow monitoring unit includes: a flow sensor 6 installed on the liquid inlet pipe 11 for detecting the flow through the liquid inlet pipe 11 and outputting a sensed flow signal; a first single-chip microcomputer connected to the signal output end of the flow sensor 6 for receiving the sensed flow signal and outputting a detection trigger signal when the sensed flow reaches a set value or an integer multiple of the set value.

[0049] The flow sensor 6 can detect the cleaning liquid flowing through the liquid inlet pipe 11. Since the cleaning liquid circulates in the pipeline system formed by the liquid inlet pipe 11, the material cylinder 1, the liquid outlet pipe 13, the connecting pipe, and the connecting pipe 14, by detecting the flow of the cleaning liquid through the liquid inlet pipe 11, combined with the use of the first single-chip microcomputer, the water quality detector 5 can be automatically controlled to detect the turbidity of the cleaning liquid when the cleaning liquid circulation reaches a set amount.

[0050] With reference to Figure 3 The prompting unit includes: a second single-chip microcomputer connected to the signal output end of the water quality detector 5 for receiving the sensed turbidity signal and calculating the turbidity change value, and outputting an alarm control signal when the turbidity is stable; a buzzer 7 connected to the signal output end of the second single-chip microcomputer and fixedly installed on the liquid storage tank 2 for receiving the alarm control signal and emitting a prompt signal.

[0051] Through the second single-chip microcomputer, the turbidity of the cleaning liquid measured by the water quality detector 5 can be detected in real time, and the buzzer 7 can be automatically controlled to emit a prompt signal (prompt sound) when the turbidity of the cleaning liquid tends to be stable. With the increase of the cleaning time, the material attached to the inside of the filling valve and the material cylinder 1 gradually mixes in the cleaning liquid. When the material completely falls off the inner wall of the filling valve and the material cylinder 1 and mixes in the cleaning liquid, the turbidity of the cleaning liquid does not fluctuate greatly with the change of flow and time. By comparing the change of the turbidity of the cleaning liquid, the technical effect of automatically detecting the cleaning effect can be achieved.

[0052] The implementation principle of the automatic positioning CIP cleaning device for the filling valve is as follows: when the filling valve needs to be cleaned, the operator can connect the connecting pipeline 14 to the filling valve to be cleaned, and control the circulating pump 3 and the filling valve to start. The circulating pump 3 draws the cleaning liquid in the liquid storage tank 2 and sends it into the cylinder 1 through the liquid inlet pipeline 11. The cleaning liquid in the cylinder 1 flows back to the circulating pump 3 through the central pipeline 12, the liquid outlet pipeline 13, the liquid storage tank 2 and the connecting pipeline. The cleaning liquid is driven by the circulating pump 3 to circulate through the cylinder 1. At the same time, the operator can start the filling valve, and the cleaning liquid in the cylinder 1 can flow to the central pipeline 12 through the filling valve from the connecting pipeline 14, so that the cleaning liquid circulates in the cylinder 1 and the filling valve at the same time, realizing the technical effect of automatically cleaning the cylinder 1 and the filling valve, and avoiding the operation of manually disassembling and cleaning the filling valve, effectively improving the convenience of cleaning the filling valve.

[0053] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
