[0002] Sampling is a crucial step in ambient air monitoring. There are a variety of sampling methods available for different sample types. Among them, Summa tank sampling is a common, efficient and reliable sample collection method.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present invention.

[0088] The cleaning apparatus for Suma tanks comprises a frame 100, a transmission device 200, a plurality of connecting support plates 300, a placement seat 400, a lifting device 600, an air path device 700 and an air path connecting component 800, such as Figures 1 to 5 As shown. The transmission device 200 is fixedly arranged on the frame 100. A plurality of connecting support plates 300 are fixedly arranged on the transmission device 200 at equal intervals. The placement seat 400 is fixedly arranged on the upper surface of the connecting support plate 300, and is used to place the soma can 500; the inner side of the placement seat 400 is an annular inclined surface, which plays a guiding and positioning role for the placement of the soma can 500.

[0089] The transmission device 200 can be a motor-gear-rack structure, where the motor is connected to the gear, the motor drives the gear to rotate, the gear drives the rack to move forward and backward, and the connecting support plate 300 is fixedly set on the rack. The transmission device 200 can also be a motor-driven chain movement, and the connecting support plate 300 is fixed on the chain. The transmission device 200 can also be a motor-driven transmission belt movement, and the transmission belt is fixed to the connecting support plate 300 to achieve the movement of the connecting support plate 300, as follows:

[0090] like Figures 6 to 9 As shown, the transmission device 200 includes a driving motor 201, a reducer 202, an annular guide rail 203, a rotating wheel 204, a rotating shaft 205, a transmission belt 206 and a slide 208; the driving motor 201 is fixedly installed inside the frame 100; the rotating shafts 205 are rotatably installed at the four corner positions of the upper end of the frame 100, the output end of the driving motor 201 is fixedly connected to the bottom of one of the rotating shafts 205, and the other three rotating shafts 205 are provided with bearing sleeves 207, and the bearing sleeves 207 are fixedly arranged inside the frame 100. The rotating shaft 205 is fixedly connected with rotating wheels 204, and the four rotating wheels 204 are connected through transmission belts 206; a reducer 202 is installed on the driving motor 201, and slides 208 are fixedly connected at equal intervals on the outer side of the conveyor belt, and the slides 208 are slidably connected to the annular guide rails 203, and the annular guide rails 203 are fixedly installed on the top of the frame 100; a connecting support plate 300 is fixedly set on the upper surface of the slide 208.

[0091] After the operator connects the lower port of the soma tank connection end 803 of the gas circuit connection component 800 to the gas collection port 501 of the soma tank 500, multiple soma tanks 500 with gas circuit connection components 800 are placed on the placement seat 400 at intervals. The transmission device 200 drives the connection support plate 300 to move, thereby driving the soma tanks 500 to move at equal intervals. After cleaning one soma tank 500, the gas circuit connection component 800 above the next soma tank 500 is moved to the bottom of the inlet and outlet straight pipe 704, and the next soma tank 500 is cleaned, which reduces the work intensity of the operator.

[0092] The lifting device 600 is fixedly arranged at the rear end of the frame 100, and includes a lifting component bracket 601 fixedly arranged on the frame 100, a lifting driving component 602 fixedly arranged on the lifting component bracket 601, and a connecting block 603 fixedly arranged at the lower end of the lifting driving component 602. One structure of the lifting driving component 602 in the lifting device 600 is an electric cylinder, and the end of the telescopic rod of the electric cylinder is fixedly connected to the connecting block 603, such as Figure 5 In addition, the lifting drive component 602 can also be a cylinder or an oil cylinder, or a motor gear rack drive structure. Any structure that can cause the connection block 603 to move linearly can be the lifting drive component 602. As long as the component can realize the lifting movement of the connection block 603 in the vertical direction, it can be used.

[0093] like Figure 5 , Fig.14 and Fig.15 As shown, the gas circuit device 700 includes a three-way solenoid valve 701, a gas charging pipe 702, a gas extraction pipe 703 and an inlet and outlet gas straight pipe 704. The three-way solenoid valve is a commonly used electromagnetic control valve, which is composed of an electromagnet and a valve body. It has two action positions (ON and OFF) and three interfaces: a first interface 7011, a second interface 7012 and a third interface 7013. The three-way solenoid valve 701 is installed on the connecting block 603; the first interface 7011 of the three-way solenoid valve 701 is connected to the upper end of the inlet and outlet gas straight pipe 704; the second interface 7012 of the three-way solenoid valve 701 is connected to one end of the gas charging pipe 702, and the other end of the gas charging pipe 702 is connected to the cleaning gas tank; the third interface 7013 of the three-way solenoid valve 701 is connected to one end of the gas extraction pipe 703, and the other end of the gas extraction pipe 703 is connected to the vacuum pump.

[0094] The upper end of the gas path connecting component 800 is movably connected to the lower end of the gas inlet and outlet straight pipe 704, and the lower end of the gas path connecting component 800 is detachably connected to the gas collection port 501 of the Suma tank 500.

[0095] The driving motor 201 drives the rotating shaft 205 to rotate, the rotating shaft 205 drives the rotating wheel 204 to rotate, the rotating wheel 204 drives the transmission belt 206 to rotate, the transmission belt 206 drives the slide 208 to move, and then drives the connecting support plate 300 to slide along the annular guide rail 203, thereby driving the Suma tank 500 to move at equal intervals.

[0096] The lifting device 600 drives the lifting of the three-way solenoid valve 701, and the lifting of the three-way solenoid valve 701 drives the lifting of the inlet and outlet straight pipes 704, thereby realizing the connection and disconnection of the inlet and outlet straight pipes 704 and the gas path connecting component 800.

[0097] By controlling the opening and closing of the interface of the three-way solenoid valve 701, the flow control of the gas during the cleaning process is realized. After the inlet and outlet straight pipes 704 and the gas path connecting component 800 are connected, the second interface 7012 of the three-way solenoid valve 701 is closed, and the third interface 7013 of the three-way solenoid valve 701 is opened. After the vacuum pump is turned on, the gas inside the Suma tank 500 is extracted. After a period of time, the third interface 7013 of the three-way solenoid valve 701 is closed, and the second interface 7012 of the three-way solenoid valve 701 is opened, and the cleaning gas inside the cleaning gas tank is flushed into the Suma tank 500. The commonly used gas is nitrogen. In this cycle, the inside of the Suma tube tank is cleaned.

[0098] The tank cleaning instrument of the Suma tank of the present invention drives the connecting support plate to move through the transmission device, and the connecting support plate drives the Suma tank to move, and drives the air inlet and outlet straight pipes to move downward through the lifting device. After the air inlet and outlet straight pipes are connected to the air path connecting components, the interior of the Suma tank is cyclically vacuumed and filled with cleaning gas to achieve cleaning of the interior of the Suma tank. After the cleaning is completed, the lifting device drives the air inlet and outlet straight pipes to move upward, and the air inlet and outlet straight pipes are separated from the air path connecting components. The transmission device moves the next Suma tank with the air path connecting components to the bottom of the air inlet and outlet straight pipes, thus completing the internal cleaning of multiple Suma tanks. The Suma tank cleaning instrument has a sophisticated structural design, realizes the cleaning work of multiple Suma tanks at one time, reduces the labor intensity of the operator, and has high cleaning stability of the Suma tank.

[0099] like Figures 10 to 12 As shown, the slide 208 includes a slot block 2081, one side of the slot block 2081 is fixedly connected to a bearing mounting plate 2082, and the upper part of the bearing mounting plate 2082 is fixedly connected to the connecting support plate 300. At least two bearing pulleys 2083 are arranged at the bottom of the bearing mounting plate 2082, and the bearing pulleys 2083 are slidably connected to the annular guide rail 203, and the other side of the slot block 2081 corresponding to the bearing mounting plate 2082 is fixedly connected to a bayonet 2084, and the bayonet 2084 is fixedly connected to the transmission belt 206. Four bearing pulleys 2083 are arranged at the bottom of the bearing mounting plate 2082 in this embodiment. Fig.13 As shown, the connecting support plate 300 is fixedly arranged on the upper part of the bearing mounting plate 2082 .

[0100] Specifically, a motor seat 209 is fixedly disposed in the frame 100, and the drive motor 201 is installed in the motor seat 209. Figure 8 As shown; the frame 100 is provided with a guide rail base plate 2010 on the top, and the annular guide rail is fixedly disposed on the guide rail base plate 2010, as shown Figure 7 shown.

[0101] The lifting drive component 602 drives the connection block 603 to move up and down, driving the three-way solenoid valve 701 to move up and down, and then driving the inlet and outlet straight pipe 704 to move up and down. After the inlet and outlet straight pipe 704 moves downward and the inlet and outlet straight pipe 704 is connected to the gas path connecting component 800, the lifting drive component 602 stops running and performs the cleaning process of the interior of the Suma tank 500. After the cleaning is completed, the lifting drive component 602 drives the connection block 603 to move upward, and the inlet and outlet straight pipe 704 is disconnected from the gas path connecting component 800.

[0102] The straight air inlet and outlet pipes 704 are hard pipes, which can be connected to the air path connecting component 800 ; the inflation pipe 702 and the air extraction pipe 703 are soft pipes, which move with the connecting block 603 .

[0103] An adsorption filter (not shown) is provided on the exhaust pipe 703, and the adsorption filter is connected to the inside of the exhaust pipe 703. The organic pollutants and water vapor extracted from the Suma tank 500 are absorbed by the adsorption filter and turned into clean gas, which is discharged from the vacuum pump. While cleaning the Suma tank 500, it can also effectively prevent the organic pollutants in the organic waste from volatilizing into the air, ensuring the safety of the experiment and preventing the operator from inhaling the polluted gas discharged from the Suma tank 500 and affecting their health.

[0104] The controller 900 is also provided inside the rack 100, and a touch screen bracket 1000 and a touch screen 1100 are fixed to one side of the rack 100. Figure 1 and Figure 4 As shown, the controller 900 is electrically connected to the touch screen 1100, and the lifting drive component 602, the transmission device 200, the three-way solenoid valve 701 and the touch screen 1100 are electrically connected to the controller 900. The touch screen 1100 can be used to input and set cleaning control conditions such as the pressure of the cleaning gas filled into the cleaning gas tank, the speed of the cleaning gas, the vacuum pressure, the speed of vacuuming, the number of cycles of filling the cleaning gas-vacuuming, etc.

[0105] The device also includes: a positioning block 1200 fixed on the outer end surface of the connecting support plate 300 and a positioning detection sensor 1300 fixed on the lifting component bracket 601, such as Figure 2 As shown. The positioning detection sensor 1300 is electrically connected to the controller 900. The positioning detection sensor 1300 detects a positioning block 1200 connected to the outer side of the support plate 300. At this time, the gas path connecting component 800 on the top of the Suma tank 500 connected to the support plate is aligned with the inlet and outlet straight pipe 704, ensuring that the lifting device 600 drives the inlet and outlet straight pipe 704 to be accurately connected with the gas path connecting component 800.

[0106] It also includes a pressure sensor 1500 disposed on the inlet and outlet straight pipe 704, such as Figure 5The pressure sensor 1500 is electrically connected to the controller 900. The pressure sensor 1500 is used to detect the pressure of the cleaning gas filled into the Summa tank 500 and the vacuum pressure inside the Summa tank 500 when evacuating.

[0107] The transmission device 200 drives the connecting support plate 300 to move, thereby driving the Suma tanks 500 to move at equal intervals. When the positioning detection sensor 1300 detects the positioning block 1200, the transmission device 200 stops running, and the lower end of the air inlet interface is aligned with the upper end of the air outlet interface, ensuring that the air inlet interface is accurately connected to the air outlet interface when the lifting device 600 drives the air inlet and outlet straight pipes 704 to descend, thereby realizing the automatic control of the Suma tank cleaning instrument. After a Suma tank 500 is cleaned, the transmission device 200 is started. When the positioning detection sensor 1300 detects the positioning block 1200 on the outer end face of the next connecting support plate 300, the transmission device 200 stops running and cleans the next Suma tank 500.

[0108] The scanner 1400 is fixedly mounted on the lifting component bracket 601 and electrically connected to the controller 900. Figure 2 When the positioning detection sensor 1300 detects the positioning block 1200, the scanner 1400 identifies the ID code on the Summa tank 500 at the cleaning position and transmits the information of the Summa tank 500 to the controller 900, and displays and stores the records on the touch screen 1100, thereby realizing the intelligent recording of the Summa tank cleaning instrument and reducing the workload of the operator.

[0109] The tank cleaning equipment of Suma tank can be used automatically and intelligently, so as to achieve precise control of the cleaning process and avoid waste of cleaning gas.

[0110] The embodiment of the present invention provides an inlet and outlet straight pipe 704 and an air path connecting component 800, which are specifically as follows:

[0111] The interior of the inlet and outlet straight pipe 704 is a straight pipe channel 7041, and the bottom end of the inlet and outlet straight pipe 704 is provided with at least one air hole 7042 along the circumference. Fig.19 and Fig. 20 shown.

[0112] like Figure 21 to Figure 26 As shown, the gas path connecting component 800 includes a cylindrical joint body 801, the upper end of the joint body 801 is a straight tube connecting end 802; the lower end of the joint body 801 is a Suma tank connecting end 803, and a connecting piece lower end channel 804 is axially arranged in the Suma tank connecting end 803, and the end of the Suma tank connecting end 803 is detachably connected to the gas collection port 501 of the Suma tank 500.

[0113] A cylindrical groove 805 is provided inside the straight pipe connection end 802, and a first annular groove 806 and a second annular groove 807 are provided inside the cylindrical groove 805 along the circumferential direction, and a first sealing gasket 808 and a second sealing gasket 809 are provided in the first annular groove 806 and the second annular groove 807, respectively. Since the first sealing gasket 808 and the second sealing gasket 809 are respectively sleeved on the first annular groove 806 and the second annular groove 807, the first sealing gasket 808 and the second sealing gasket 809 are prevented from falling off, and finally the sealing effect is better. The space of the cylindrical groove 805 between the first sealing gasket 808 and the second sealing gasket 809 forms a buffer zone 810; when the inlet and outlet straight pipe 704 is connected to the gas path connection component 800, the inlet and outlet straight pipe 704 is movably sleeved in the first sealing gasket 808 and the second sealing gasket 809, so as to prevent the external gas from entering the internal space during the connection process and causing gas pollution.

[0114] A limiting cylinder 811 is arranged in the cylindrical groove 805 and coincides with the central axis of the cylindrical groove 805. The structure of the limiting cylinder 811 is as follows: Figure 27 to Figure 29 As shown, the limiting cylinder 811 is a cylindrical structure with an open upper end and a closed lower end; the outer diameter of the limiting cylinder 811 is smaller than the diameter of the cylindrical groove 805, and an internal air flow channel 812 communicating with the lower end channel 804 of the connector is formed between the limiting cylinder 811 and the inner wall of the joint body 801. A movable column 815 is provided in the inner cavity of the limiting cylinder 811, and the central axis of the movable column 815 coincides with the central axis of the limiting cylinder 811. The movable column 815 can move up and down in the inner cavity of the limiting cylinder 811 along the central axis direction.

[0115] The top of the movable column 815 is connected to a truncated pedestal seat 817, and the central axis of the truncated pedestal seat 817 and the movable column 815 coincide with each other. Fig.30 As shown. The connection method between the truncated pedestal seat 817 and the movable column 815 is slot-connected, threaded, bonded, or integrally formed. The diameter of the upper bottom surface of the truncated pedestal seat 817 is smaller than the diameter of the lower bottom surface, and the diameter of the lower bottom surface of the truncated pedestal seat 817 is larger than the diameter of the movable column 815, and the lower bottom surface of the truncated pedestal seat 817 is connected to the movable column 815. The diameter of the lower bottom surface of the truncated pedestal seat 817 is larger than the inner diameter of the limiting cylinder 811, and the truncated pedestal seat 817 moves between the limiting cylinder 811 and the second sealing gasket 809. The diameter of the upper bottom surface of the truncated pedestal seat 817 is larger than the inner diameter of the inlet and outlet straight pipe 704, and the bottom port of the inlet and outlet straight pipe 704 is movably connected to the upper bottom surface of the truncated pedestal seat 817. During the process of inflating the interior of the Suma tank 500 , when the bottom port of the air inlet and outlet straight pipe 704 contacts the upper bottom surface of the truncated pedestal 817 , the gas in the straight pipe channel 7041 can flow out from the air hole 7042 of the air inlet and outlet straight pipe 704 to the internal air flow channel 812 .

[0116] like Fig.24As shown, a spring 816 is provided in the inner cavity of the limiting cylinder 811, and one end of the spring 816 is fixed at the middle position of the bottom surface of the inner cavity of the limiting cylinder 811, and the fixing method can be bonding or clamping, and the other end of the spring 816 is against the bottom surface of the movable column 815.

[0117] While the second sealing gasket 809 plays a sealing role, the second sealing gasket 809 and the limiting cylinder 811 play a role in limiting the movement positions of the two ends of the truncated pedestal seat 817.

[0118] A positioning support 818 is fixedly provided on the lower end surface of the limiting cylinder 811, so that the central axis of the limiting cylinder 811 coincides with the central axis of the cylindrical groove 805, while ensuring that the internal air flow channel 812 is connected to the lower end channel 804 of the connecting piece. The fixing method is bonding, clamping or threaded connection.

[0119] The combined structure of the first annular groove 806 and the second annular groove 807 and the corresponding first sealing gasket 808 and second sealing gasket 809 ensures the sealing effect of the internal space during the connection process between the inlet and outlet straight pipe 704 and the gas path connecting component 800, the ventilation process and the separation process, and prevents external gas from entering the internal space and affecting the purity of the internal circulating gas.

[0120] The setting of the spring 816 inside the limiting cylinder 811 can realize the automatic resetting of the truncated pedestal seat 817, which is more convenient to use; at the same time, it prevents the external gas from entering the internal space of the gas path connecting component 800 during the process of removing the inlet and outlet straight pipes 704 from the gas path connecting component 800, thereby affecting the purity of the gas introduced next time.

[0121] A preferred embodiment of the present invention: a third annular groove 813 is opened in the inner cavity of the limiting cylinder 811 along the circumferential direction near the opening position, a third sealing gasket 814 is arranged in the third annular groove 813, a movable column 815 is sleeved in the third sealing gasket 814, and the movable column 815 can slide in the third sealing gasket 814.

[0122] By providing the third sealing gasket 814 at the opening of the limiting cylinder 811, a closed space easily containing gas formed inside the limiting cylinder 811 due to the up and down movement of the movable column 815 in the limiting cylinder 811 is avoided, thereby avoiding gas pollution.

[0123] Another preferred embodiment of the present invention: the structure of the positioning support member 818 is as follows: Fig.31 and Fig.32As shown, the positioning support 818 includes a positioning rod 8181 and at least one support arm 8182 located on the top surface of the positioning rod 8181. In this embodiment, two symmetrical support arms 8182 are provided. The positioning rod 8181 is stuck in the lower end channel 804 of the connector, and plays a role in aligning the central axis of the positioning limit cylinder 811 with the central axis of the cylindrical groove 805. The upper end surface of the support arm 8182 contacts the lower end surface of the limiting cylinder 811, and the lower end surface of the support arm 8182 contacts the bottom end surface of the cylindrical groove 805, and plays a role in supporting the limiting cylinder 811; the positioning rod 8181 is not completely in contact with the side wall of the lower end channel 804 of the connector, and the positioning rod 8181 is partially in contact with the side wall of the lower end channel 804 of the connector, ensuring that the internal airflow channel 812 is connected to the lower end channel 804 of the connector.

[0124] Furthermore, in order to satisfy the requirement of a large flow of gas passing through the space between the internal air flow channel 812 and the lower end channel 804 of the connector, the positioning support member 818 is a shell structure, forming a positioning support member cavity 8183, such as Fig.33 When the cleaning gas is charged into the Suma tank 500 , part of the gas flow enters the lower end channel 804 of the connector from the internal gas flow channel 812 , and the other part of the gas flow flows from the outer side of the positioning support 818 to the lower end channel 804 of the connector.

[0125] The first sealing gasket 808, the second sealing gasket 809 and the third sealing gasket 814 are made of silicone rubber material, which are deformed by extrusion and return to their original shape after the external force is removed, thereby ensuring the sealing effect.

[0126] The gas path connection component and the inlet and outlet gas straight pipe provided in the embodiment of the present invention simplify the connection method of the two. Compared with the traditional connection method, the gas path connection component and the inlet and outlet gas straight pipe can not only reduce the connection time and labor cost, but also ensure the sealing of the connection process, intermediate process and disconnection process.

[0127] Working principle of the inlet and outlet straight pipe 704 and the gas path connecting component 800:

[0128] During the process of inserting the air inlet and outlet straight pipe 704 into the air path connecting component 800, the central axis of the air path connecting component 800 and the air inlet and outlet straight pipe 704 coincide, the first sealing gasket 808 and the second sealing gasket 809 are respectively in close contact with the outer side of the air inlet and outlet straight pipe 704, the air hole 7042 of the air inlet and outlet straight pipe 704 passes through the buffer zone 810 between the first sealing gasket 808 and the second sealing gasket 809, and after the bottom port of the air inlet and outlet straight pipe 704 contacts the upper bottom surface of the round pedestal seat 817, the air inlet and outlet straight pipe 704 further pushes the round pedestal seat 817 to move toward the limiting cylinder 811, and the spring 816 is compressed by the movable column 815. The bottom air hole 7042 of the air inlet and outlet straight pipe 704 further moves downward toward the cylindrical groove 805 after passing through the buffer zone 810. When the bottom surface of the truncated pedestal seat 817 is in contact with the open end of the limiting cylinder 811, the truncated pedestal seat 817 stops moving, and the air hole 7042 moves to the inner space below the second sealing gasket 809. Figures 16 to 18 When the cleaning gas is charged into the interior of the Suma tank 500, the cleaning gas flows from the straight pipe channel 7041 to the air hole 7042 and then to the internal space, and flows to the lower end channel 804 of the connector through the internal air flow channel 812, and flows out of the gas path connecting component 800 to the Suma tank 500. During the vacuuming process, the air flow direction is opposite to the air flow direction of the cleaning gas, and the connection state of the inlet and outlet straight pipe 704 and the gas path connecting component 800 and the internal structure of the gas path connecting component 800 remain unchanged.

[0129] When the movable column 815 loses the pressure of the air inlet and outlet straight pipe 704, the bottom end of the air inlet and outlet straight pipe 704 moves toward the upper end of the joint body 801, the spring 816 rebounds, the air inlet and outlet straight pipe 704 and the pedestal seat 817 move synchronously, and after the side of the pedestal seat 817 abuts against the second sealing gasket 809, the air inlet and outlet straight pipe 704 is separated from the pedestal seat 817, and then the air inlet and outlet straight pipe 704 is removed from the air path connecting component 800, thereby achieving automatic resetting of the pedestal seat 817, which is more convenient to use and avoids the outside gas from entering the internal space of the air path connecting component 800 during the process of removing the air inlet and outlet straight pipe 704 from the air path connecting component 800, thereby affecting the purity of the gas when the air inlet and outlet straight pipe 704 and the air path connecting component 800 are connected next time.

[0130] The embodiment of the present invention also provides a method for using the above-mentioned Suma tank cleaning device, comprising the following steps:

[0131] S1, connect the lower port of the Suma tank connection end 803 of the gas path connection component 800 to the gas collection port 501 of the Suma tank 500;

[0134] S4, the air inlet and outlet straight pipe 704 is aligned with the air path connecting component 800 above a Suma tank 500, and the transmission device 200 is stopped; the lifting device 600 operates to make the connecting block 603 move downward, driving the air inlet and outlet straight pipe 704 to move downward, and the air inlet and outlet straight pipe 704 is connected with the air path connecting component 800;

[0135] S5, the second interface 7012 of the three-way solenoid valve 701 is closed, the third interface 7013 of the three-way solenoid valve 701 is opened, and after the vacuum pump is turned on, the gas inside the Suma tank 500 is extracted; after the vacuum setting time is reached, the third interface 7013 of the three-way solenoid valve 701 is closed, and the second interface 7012 of the three-way solenoid valve 701 is opened, and the gas inside the cleaning gas tank is flushed into the Suma tank 500;

[0136] S6, repeat step S5, and cycle through the process of vacuuming and filling with cleaning gas;

[0137] S7, after the internal cleaning of the Suma tank 500 is completed, the lifting device 600 controls the connecting block 603 to move upward, driving the inlet and outlet straight pipes 704 to move upward, and the inlet and outlet straight pipes 704 and the gas path connecting component 800 are separated;

[0138] S8. Repeat the processes of S3 to S7 to complete the cleaning of multiple Suma tanks 500.
