Description

Technical Field

[0001] The utility model relates to the technical field of filling metering control, in particular to a CIP / SIP metering pump liquid channel connecting device. Background Art

[0002] Plunger pumps with CIP / SIP (cleaning in place / sterilization in place) functions are mainly used in high-precision constant-volume filling systems for pharmaceuticals, foods, cosmetics, chemicals, and medical analytical instruments. They have the advantages of high filling accuracy and easy cleaning and sterilization.

[0003] The plunger pump pulls the metering rod outward from the plunger pump sleeve, the volume of the plunger chamber increases, a vacuum is generated to suck in liquid, and conversely, the rotary valve or slot valve is rotated at a certain angle to align the rotary valve or slot valve with the liquid outlet, and the metering rod is pushed into the plunger pump sleeve, the volume of the chamber decreases, and the liquid is discharged to achieve fluid filling and metering, such as a plunger metering pump for aqueous filling with publication number CN213574491U.

[0004] Compared with the traditional plunger pump, the structure of the plunger pump with CIP / SIP function is more complicated. It needs four channels to connect with the outside, namely the fluid suction port, the fluid discharge port, and the other two channels for realizing the CIP / SIP function.

[0005] Hoses and connectors are required on each channel. Multiple channels make the pipes on the CIP / SIP metering pump complicated, which is not only unsightly, but also very inconvenient to disassemble and install. In addition, due to the limited service life of the hose, multiple hoses and connectors also increase the manufacturing and use costs.

[0006] In addition, it is difficult to exhaust the bubbles through the long pipe, which affects the filling accuracy and also produces liquid residue. On the one hand, it wastes the liquid medicine, and on the other hand, it increases the difficulty of cleaning during online cleaning, which is time-consuming and water-consuming and difficult to clean.

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The utility model provides Figure 1-Figure 6 A CIP / SIP metering pump liquid channel connecting device shown includes a plunger pump fixing plate 12 and a plurality of CIP / SIP plunger pumps 1 arranged on the plunger pump fixing plate 12, the CIP / SIP plunger pump 1 includes a plunger pump sleeve 2, a transition connecting plate 14 is provided on one side of the plunger pump fixing plate 12, and an upper liquid channel opening 6, a middle liquid channel opening 7 and a lower liquid channel opening 8 are provided on the side of the plunger pump sleeve 2 facing the transition connecting plate 14 from top to bottom, so the connecting device is provided with a row of upper liquid channel openings 6, a row of middle liquid channel openings 7 and a row of lower liquid channel openings 8 from top to bottom, and the plunger pump fixing plate 12 can be installed on the large column of the frame, and can also be fixed on the transition connecting plate 14.

[0033] Three rows of transition connecting pipes 15 are provided on the transition connecting plate 14 from top to bottom. The transition connecting plate 14 can be an integral body or a split design, divided into three blocks, each block corresponding to a row of transition connecting pipes 15, the transition connecting pipes 15 in the top row correspond one-to-one with the upper liquid channel openings 6, the transition connecting pipes 15 in the middle row correspond one-to-one with the middle liquid channel openings 7, and the transition connecting pipes 15 in the bottom row correspond one-to-one with the lower liquid channel openings 8. An upper liquid centralized distributor 19, a middle liquid centralized distributor 20 and a lower liquid centralized distributor 21 are provided on the side of the transition connecting plate 14 away from the plunger pump fixing plate 12 from top to bottom. The three can be a single body or an integrated body, and the three can be fixed on the transition connecting plate 14. The upper liquid channel opening 6, the middle liquid channel opening 7 and the lower liquid channel opening 8 are respectively connected to the upper liquid centralized distributor 19, the middle liquid centralized distributor 20 and the lower liquid centralized distributor 21 through three rows of transition connecting pipes 15.

[0034] All upper liquid channel openings 6 are concentrated on the upper liquid concentrated distributor 19 through the transition connecting pipe 15. Similarly, all middle liquid channel openings 7 are concentrated on the middle liquid concentrated distributor 20, and all lower liquid channel openings 8 are concentrated on the lower liquid concentrated distributor 21. In this way, multiple pipelines with the same function are concentrated, reducing the setting of rubber hoses, making the connection device more neat and beautiful, simpler in structure, more convenient to disassemble and assemble, and saving the cost of complicated rubber hoses and joints. In addition, since the rubber hose is eliminated, the problem of difficulty in exhausting bubbles in the rubber hose is avoided, the accuracy of filling metering is improved, the waste of residual liquid is reduced, the online cleaning time is shortened, and cleaning water is saved.

[0035] When using the transition pipe 15 for connection, it is necessary to ensure good sealing. Figure 3-Figure 6 As shown, the upper liquid channel opening 6 includes a channel hole 10 opened on the plunger pump sleeve 2, and the outward end of the channel hole 10 is provided with a liquid channel sealing cylindrical hole 9 fixed to the outer end of the plunger pump sleeve 2, and the two ends of the channel hole 10 are respectively communicated with the internal chamber of the plunger pump sleeve 2 and the liquid channel sealing cylindrical hole 9, and the structures of the upper liquid channel opening 6, the middle liquid channel opening 7 and the lower liquid channel opening 8 are exactly the same, only the positions are different, and the external shape of the liquid channel sealing cylindrical hole 9 can be cylindrical, regular polygonal or other shapes.

[0036] The transition connecting pipe 15 passes through the transition connecting plate 14. A hole for installing the transition connecting pipe 15 is reserved on the transition connecting plate 14. The transition connecting pipe 15 passes through the transition connecting plate 14 through the hole. Both ends of the transition connecting pipe 15 are sleeved with a sealing gasket 16 and two O-rings 17. A card slot 18 is fixedly provided on the transition connecting pipe 15.

[0041] A plunger pump fixing clamp 11 is provided on the plunger pump sleeve 2, and the CIP / SIP plunger pump 1 is installed on the plunger pump fixing plate 12 through the plunger pump fixing clamp 11. A plurality of fixing plate screws 13 for fixing the CIP / SIP plunger pump 1 are provided through threads on the side of the plunger pump fixing plate 12 away from the transition connecting plate 14.
