DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be clearly and completely described in the following by combining with the drawings in the embodiments of the utility model, obviously, the described embodiments only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0030] Please refer to Figure 1 - Figure 4 As shown in FIG. 1, a CIP workstation for automatic completion of alkali preparation, alkali supplement and hot water disinfection comprises a plurality of tank bodies 1 arranged on the ground through legs, which can be used for stirring, homogenization, fermentation and chemical reaction, etc. A water inlet pipe 2 is fixedly connected to the center of the top of the tank body 1 to communicate the inside and outside of the tank body 1. A cleaning ball 3 is fixedly connected to the lower end of the water inlet pipe 2, and a plurality of holes are arranged on the cleaning ball 3 to spray cleaning liquid into the tank body 1. A fixed jacket 5 is arranged on the outer wall of the tank body 1 to keep the tank body 1 warm and control the temperature. A differential pressure liquid level sensor 4 is arranged at the bottom of the tank body 1 to detect the height of the cleaning liquid in the tank body 1.

[0031] Please refer to Figure 3 As shown in FIG. 1, a tank body 1 is further fixedly connected with a breather pipe 6 to communicate the inside and outside of the tank body 1, which is used for pressure relief of the tank body 1. A first normally open breather valve 7 is arranged on the breather pipe 6. When the gas in the tank body 1 expands or shrinks due to temperature change or material in and out, the first normally open breather valve 7 can timely discharge or inhale the gas to keep the pressure inside the tank balanced with the outside.

[0032] A breather 8 is arranged on the breather pipe 6 corresponding to the position above the first normally open breather valve 7. For some tank bodies 1 storing volatile chemicals, the breather 8 helps to control or reduce the odor leakage, prevent the odor of volatile substances from polluting the surrounding environment, and avoid the entry of external dust particles into the tank body 1.

[0033] A drain valve 9 is arranged on the breather 8. If water accumulates in the breather 8 for a long time, it may cause corrosion of the internal parts of the breather 8 and the connecting pipe 15, valves, etc. The drain valve 9 can effectively remove the water to reduce the risk of system corrosion and prolong the service life of the equipment.

[0034] A second normally open breather valve 10 is arranged on the breather pipe 6 corresponding to the position above the breather 8. It plays a redundant protection role when the first normally open breather valve 7 fails to work. It allows air or gas to enter and exit the tank, and prevents the tank body 1 from being damaged when the gas pressure in the tank exceeds the set value.

[0035] A muffler 11 is arranged on the breather pipe 6 corresponding to the position above the second normally open breather valve 10. When the gas rapidly enters and exits the tank body 1, it will produce a large noise. The muffler 11 reduces noise pollution by muffling and relieving the speed change of the gas flow, and protects the quietness of the operating environment.

[0036] Please refer to Figures 1-4 As shown in FIG. 1, the CIP workstation for automatic completion of alkali preparation, alkali supplement and hot water disinfection further comprises a concentrated alkali barrel 12 for storing alkaline cleaning liquid.

[0038] A second distribution pipe 14 is connected with the discharge port of the tank body 1 through a pipeline; a flow switch 19 is installed on the second distribution pipe 14, which is used for adjusting the opening and closing of the second distribution pipe 14; a centrifugal pump 18 is also installed on the second distribution pipe 14.

[0039] The output end of the centrifugal pump 18 is fixedly connected with a connecting pipe 15; the other end of the connecting pipe 15 is connected with a heat exchanger 17 together with the first distribution pipe 13, and the first distribution pipe 13 and the connecting pipe 15 are connected with the output end and the input end of the heat exchanger 17 respectively.

[0040] The alkali preparation pipe 20 is fixedly connected with the second distribution pipe 14 corresponding to the position between the tank body 1 and the flow switch 19, and the other end of the alkali preparation pipe 20 is communicated with the concentrated alkali barrel 12; the pneumatic valve 21 is installed on the alkali preparation pipe 20 close to the second distribution pipe 14. The pneumatic valve 21 is controlled to open and close by compressed air, so as to realize the automatic control of the alkali liquid flowing into the second distribution pipe 14, thereby adjusting the required amount of alkali liquid in the tank body 1.

[0041] The diaphragm valve 23 is installed on the alkali preparation pipe 20 close to the concentrated alkali barrel 12. The diaphragm valve 23 opens and closes the fluid passage through the elastic diaphragm, and can accurately control the inflow of the alkali liquid in the concentrated alkali barrel 12, so as to ensure that the alkali liquid flows to the second distribution pipe 14 as required.

[0042] The one-way valve 22 is installed on the alkali preparation pipe 20 corresponding to the positions between the diaphragm valve 23 and the pneumatic valve 21. The one-way valve 22 allows the alkali liquid to flow in one direction, and prevents the alkali liquid from flowing back from the second distribution pipe 14 or the tank body 1 to the concentrated alkali barrel 12.

[0043] In order to facilitate the understanding of the above technical scheme of the utility model, the working principle or operation mode of the utility model in the actual process will be described in detail as follows:

[0048] The heating of the cleaning liquid is realized by the heat exchanger 17, steam is introduced into the heat exchanger 17, and the heat exchange between the steam and the cleaning liquid is used to heat the cleaning liquid, and the equipment in the rear tank 1 can be sterilized by 121℃ superheated water.

[0049] When the cleaning liquid circulates to the second distribution pipe 14, the alkali pipe 20 synchronously introduces the alkaline cleaning liquid in the concentrated alkali barrel 12 into the second distribution pipe 14 to mix with the circulating cleaning liquid, so as to realize the purpose of alkali supplement.

[0050] The automatic detection of the concentration and content of the alkaline cleaning liquid is realized by the cooperation of the differential pressure liquid level sensor 4, the flow meter 16 and the liquid level sensor in the concentrated alkali barrel 12, and the centrifugal pump 18 is used to realize the automatic completion of the alkali supplement and the superheated water sterilization process of the rear equipment, so that even after multiple circulation and all-round cleaning, the alkaline concentration of the cleaning liquid can still be used for cleaning, the use frequency of the cleaning liquid is improved, the replacement cycle of the circulating liquid is reduced, the cleaning degree in the tank 1 is improved, and the cleaning is convenient and time-saving.
