Description

Cleaning test device and method for clean container equipment

Technical Field

The invention relates to the technical field of clean container equipment, in particular to a cleaning testing device and method of clean container equipment.

Background

With the development of the technology of clean container equipment, the cleaning of the clean container equipment is highly valued by pharmaceutical factories, and the cleaning test of the riboflavin coverage is particularly important, so that the cleaning verification of the clean container equipment becomes a critical problem for each large pharmaceutical equipment manufacturer.

In order to meet the cleaning and verification requirements of pharmaceutical factories on clean container equipment, a FAT test qualification report before the equipment leaves a factory becomes an important basis for cleaning and verification. The FAT stage is to form a data file with basis and provide a record report and an image file. The formation of image files before and after testing is easy to implement, but how to form accurate and representative data is a difficult problem for many pharmaceutical equipment manufacturers.

Conventionally, the riboflavin cleaning test process requires a specialized operator to track the whole process, the operator needs to adjust the opening of the manual ball valve according to the float flowmeter and the pressure indication number, and when the manual ball valve is adjusted to a preset value, the indication numbers of the float flowmeter and the pressure indication number are manually observed and recorded. In addition, before the riboflavin cleaning test, the riboflavin needs to be manually prepared and uniformly sprayed on all pipe orifices and access holes by a spray can. When the manually prepared riboflavin solution is sprayed, the condition of non-uniformity in spraying is easy to generate, particularly when the inner diameter size of clean container equipment (such as a storage tank) is large, the riboflavin on the inner surface of the upper end socket of the tank body cannot be sprayed during the manual spraying action, so that the local part cannot be covered, further, the performance test of the clean container equipment cannot be accurately performed, and the controllability is poor.

The steps can be sequentially completed by controlling the first control piece 51, the second control piece 52, the third control piece 53, the fourth control piece 54, the first pump body 81 and the second pump body 82, so that the degree of automation is high; in addition, in the spraying step, the riboflavin solution in the riboflavin buffer tank 10 is pumped to the sample injection pipe 91 of the to-be-detected tank 90 through the first pump body 81, the spray header 93 which enters from the sample injection pipe 91 and is connected through the sample injection pipe 91 is sprayed to the inner wall surface of the to-be-detected tank 90, whether the spraying function of the spray header 93 is normal or not can be correspondingly judged by observing whether the spray header 93 can spray the riboflavin solution to the whole inner wall surface of the to-be-detected tank 90 or not, and whether the structure of each functional pipe orifice is normal or reasonable can be correspondingly judged by observing whether each functional pipe orifice on the inner wall surface of the to-be-detected tank 90 has the riboflavin or not; in addition, in the cleaning step, purified water in the purified water buffer tank 20 is pumped to the sample injection pipe 91 of the tank to be tested 90 through the first pump body 81, the purified water enters from the sample injection pipe 91 and is sprayed to the inner wall surface of the tank to be tested 90 through the spray header 93 connected with the sample injection pipe 91, whether the spraying function of the spray header 93 is normal or not can be correspondingly judged by observing whether the riboflavin solution attached to the whole inner wall surface of the tank to be tested 90 can be cleaned, whether the inner wall of the tank to be tested 90 meets the sanitary structure or not, whether the polishing degree requirement of the inner wall of the tank to be tested 90 meets the preset requirement or not, and whether the structure of each functional pipe orifice is normal or reasonable or not can be correspondingly judged by observing whether each functional pipe orifice on the inner wall surface of the tank to be tested 90 has riboflavin or not.

Referring to fig. 2, fig. 2 is a schematic structural view of a cleaning test device of a cleaning container apparatus according to another embodiment of the present invention. Further, the cleaning test device of the clean container apparatus further includes a first liquid level sensor 110, a second liquid level sensor 120, and a third liquid level sensor 130. A first level sensor 110 is provided on the riboflavin buffer 10 for acquiring the level height of the riboflavin buffer 10. The second level sensor 120 is disposed on the purified water buffer tank 20 for acquiring the level of the purified water buffer tank 20. The third level sensor 130 is used to obtain the level of the tank 90 to be measured. Thus, the liquid level in the riboflavin buffer 10 is obtained by the first liquid level sensor 110, and it can be timely judged in the configuration step whether the purified water added to the riboflavin buffer 10 reaches a preset amount (specifically, for example, 50 liters or 200 liters); the liquid level height in the purified water buffer tank 20 is obtained through the second liquid level sensor 120, so that the volume of the purified water stored in the purified water buffer tank 20 can be well mastered, and the purified water can be timely supplemented; the third liquid level sensor 130 is used for acquiring the liquid level height in the tank 90 to be measured, so that the liquid level height in the tank 90 to be measured can be well mastered, the liquid level height in the tank 90 to be measured controls the second pump 82 to work, and the phenomenon that the second pump 82 still works when no liquid exists in the tank 90 to be measured can be avoided.

Further, the cleaning test device of the clean container apparatus further comprises a controller. The controller is electrically connected to the first liquid level sensor 110, the second liquid level sensor 120, the third liquid level sensor 130, the first control member 51, the second control member 52, the third control member 53, the fourth control member 54, the first pump body 81 and the second pump body 82, respectively.

Specifically, the cleaning test device of the clean container apparatus further includes a touch screen 140. The touch screen 140 is electrically connected to the controller. In this way, the touch screen 140 receives the operation command of the operator, and accordingly controls the first control member 51, the second control member 52, the third control member 53, the fourth control member 54, the first pump body 81 and the second pump body 82 to operate, thereby completing the configuration step, the spraying step and the cleaning step.

The first control member 51 may be, for example, three on-off valves K1 provided on the first connection pipe 41, the second connection pipe 42, and the third connection pipe 43, or may be a two-position three-way valve, which is not limited thereto, and may be provided according to actual needs. Thus, the first control member 51 can control two pipes among the first connecting pipe 41, the second connecting pipe 42 and the third connecting pipe 43 to be communicated when operating. Specifically, the on-off valve K1 is specifically, for example, an electronically controlled on-off valve K1 or a pneumatically controlled on-off valve K1, and the two-position three-way valve is specifically, for example, an electronically controlled two-position three-way valve or a pneumatically controlled two-position three-way valve.

Referring to fig. 2, in one embodiment, the cleaning test apparatus of the clean container apparatus further includes a moving base 150. The riboflavin buffer tank 10 and the purified water buffer tank 20 are both installed on the movable base 150. Thus, the cleaning and testing device of the clean container apparatus can be conveniently moved to a position near one of the cans 90 to be tested by moving the base 150, and the sixth connecting pipe 46 is connected with the sample inlet pipe 91 of the can 90 to be tested, and the return pipe 70 is connected with the sample outlet pipe 92 of the can 90 to be tested, so that the test operation is convenient.

Generally, a water source used in the conventional riboflavin cleaning test process is derived from a purified water circulation pipe network in a workshop, the water supply pressure is about 3bar, when a plurality of using points in the workshop are simultaneously opened, the water supply quantity of the test points is unstable, the pressure value is jumped, and sometimes the water supply quantity and the water demand are inconsistent. When the water supply amount of the purified water circulation pipe network is insufficient, the water supply port of the test point is required to be externally connected to a fixed-frequency liquid supply pump, and in order to meet the water supply flow of the spray header 93 in the clean container equipment, the opening control flow can only be regulated through a manual ball valve of the outlet of the fixed-frequency liquid supply pump.

Referring to fig. 2, further, the cleaning test device of the cleaning container apparatus further includes a fourth conveying pipe 64, a third pump 83, and two first control switches K2. The sample outlet of the purified water buffer tank 20 is also communicated with a sample inlet pipe 91 of the tank to be tested 90 through a fourth conveying pipe 64. The third pump body 83 and the first control switches K2 are both disposed on the fourth conveying pipe 64, and the two first control switches K2 are respectively disposed on two sides of the third pump body 83. Thus, on the one hand, by controlling the on/off valve K1 on the third delivery pipe 63 to be opened, the on/off valve K1 on the second delivery pipe 62 to be closed, the on/off valve K1 on the first delivery pipe 61 to be opened, the on/off valve K1 on the fifth connection pipe 45 to be closed, the on/off valve K1 on the sixth connection pipe 46 to be opened, and the two first control switches K2 on the fourth delivery pipe 64 to be closed, purified water in the purified water buffer tank 20 can sequentially pass through the third delivery pipe 63, the first delivery pipe 61, the sixth connection pipe 46 and the sample introduction pipe 91 of the tank under test 90 under the suction force of the first pump body 81 to be introduced into the tank under test 90. On the other hand, by controlling the on-off valve K1 on the third delivery pipe 63 to be closed, the on-off valve K1 on the second delivery pipe 62 to be closed, and opening the two first control switches K2, the purified water in the purified water buffer tank 20 can enter the tank under test 90 through the fourth delivery pipe 64 and the sample tube 91 of the tank under test 90 under the suction force of the third pump body 83. The working power of the first pump 81 is different from that of the third pump 83, and a pump with a proper working power can be selected to work according to the requirement of the tank 90 to be tested. Specifically, the first pump body 81 has a specification of 8t/h, for example, and the third pump body 83 has a specification of 15t/h, for example. The first pump body 81, the second pump body 82, and the third pump body 83 are, for example, sanitary centrifugal pumps.

Referring to fig. 2, in one embodiment, the first delivery tube 61 includes a first tube segment 611 and a second tube segment 612 that are in communication with each other. The first pump body 81 is disposed on the first tube segment 611. The first pipe segment 611 is connected to the second and third pipes 62 and 63, respectively. The second pipe segment 612 is connected to the fifth and sixth connection pipes 45, 46, respectively. The first pipe section 611 and the second pipe section 612 are provided with an on-off valve K1. The end of the fourth transfer tube 64 communicates with the junction of the first tube segment 611 and the second tube segment 612. In this way, the fourth conveying pipe 64 may be connected to the butt joint part of the first pipe section 611 and the second pipe section 612 instead of directly connecting to the sample injection pipe 91 of the tank 90 to be tested, so that the length of the fourth conveying pipe 64 can be shortened, pipes can be saved, the cost can be reduced, and the structure can be simplified.

Referring to fig. 3, fig. 3 is a schematic structural view of a cleaning test device of a cleaning container apparatus according to another embodiment of the present invention. In one embodiment, the cleaning test apparatus of the clean container apparatus further includes a waste output connector 32, a first drain pipe 65, and a fifth control member 55. The return pipe 70 comprises a third pipe section 71 and a fourth pipe section 72 which are in communication with each other. The third pipe section 71 is connected with a sample injection pipe 91 of the to-be-measured tank 90, and the fourth pipe section 72 is communicated with a sample injection port of the riboflavin buffer tank 10. One end of the first discharge pipe 65 is connected to the junction of the third pipe section 71 and the fourth pipe section 72, and the other end of the first discharge pipe 65 is connected to the waste discharge output joint 32. The fifth control member 55 is used to control the communication of the third tube segment 71 with the fourth tube segment 72 or with the first drain tube 65. The second pump body 82 is arranged on the third pipe section 71. Thus, when the liquid in the can to be measured 90 needs to be refluxed into the riboflavin buffer tank 10, specifically for example, the riboflavin solution is reused, the fifth control member 55 controls the third pipe section 71 to be communicated with the fourth pipe section 72 and controls the third pipe section 71 to be disconnected from the first drain pipe 65, so that the liquid in the can to be measured 90 is refluxed into the riboflavin buffer tank 10 through the sample outlet pipe 92, the third pipe section 71, the fourth pipe section 72 and the sample inlet of the riboflavin buffer tank 10 of the can to be measured 90 in sequence; when it is required to discharge the liquid in the tank 90 to be tested outwards through the waste discharge outlet joint 32, specifically, for example, to discharge the cleaning liquid in the tank 90 to be tested outwards, the fifth control member 55 controls the third pipe section 71 to be communicated with the first discharge pipe 65 and controls the third pipe section 71 to be disconnected from the fourth pipe section 72, so that the liquid in the tank 90 to be tested is discharged outwards through the waste discharge outlet joint 32 sequentially through the outlet pipe 92, the third pipe section 71 and the first discharge pipe 65 of the tank 90 to be tested.

It will be appreciated that, as an alternative, when the waste liquid in the tank 90 to be tested needs to be discharged outwards, the outlet tube 92 of the tank 90 to be tested may be directly separated from the third tube section 71, so that the waste liquid in the tank 90 to be tested can be discharged outwards through the outlet tube 92 of the tank 90 to be tested.

The first control member 51 is used to control two pipes among the first, second, third and seventh connection pipes 41, 42, 43 and 47 to communicate. Thus, under the action of the first control member 51, purified water may be inputted into the purified water buffer tank 20 not only through the first connection pipe 41 and the second connection pipe 42, but also through the first connection pipe 41 and the seventh connection pipe 47. When the inner wall of the purified water buffer tank 20 needs to be cleaned, the first control member 51 generally controls the first connection pipe 41 to be communicated with the seventh connection pipe 47, the purified water supply joint 31 transmits the purified water to the seventh connection pipe 47 through the first connection pipe 41, and the seventh connection pipe 47 sprays the purified water to the inner wall of the purified water buffer tank 20 through the inlet pipe 21 and the spray header 23 of the purified water buffer tank 20, thereby playing a cleaning role.
