[0002] In ambient air monitoring, sampling is a crucial step. For different sample types, there are various sampling methods available. Among them, Summa can sampling is a relatively common, efficient and reliable sample collection method. With its unique advantages, it is mainly used for the collection and storage of gas samples, the storage of calibration gases in on-line monitoring systems, the preparation of calibration gases in laboratories, and the dilution of gas samples. The inner wall and valve body of the Summa can are inertized to ensure the stability of components during storage.

[0084] 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 fixed on the lifting component bracket 601 and a connecting block 603 fixedly arranged at the lower end of the lifting driving component 602.

[0085] As Figure 5 、 Figure 14 and Figure 15As shown in the figure, the gas circuit device 700 includes a three-way solenoid valve 701, a charging pipe 702, an air extraction pipe 703, and an air inlet / outlet straight pipe 704. The three-way solenoid valve is a commonly used electromagnetic control valve, which consists of an electromagnet and a valve body. It has two action positions (ON and OFF), and at the same time has 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 air inlet / outlet straight pipe 704; the second interface 7012 of the three-way solenoid valve 701 is connected to one end of the charging pipe 702, and the other end of the 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 air extraction pipe 703, and the other end of the air extraction pipe 703 is connected to a vacuum pump;

[0086] The upper end of the gas circuit connecting component 800 is movably connected to the lower end of the air inlet / outlet straight pipe 704, and the lower end of the gas circuit connecting component 800 is detachably connected to the gas sampling port 501 of the Summa can 500;

[0089] By controlling the opening and closing of the interfaces of the three-way solenoid valve 701, the flow of gas during the cleaning process is realized. After the air inlet / outlet straight pipe 704 and the gas circuit 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.

[0090] The tank cleaning instrument for the SUMMA can of the present utility model drives the connecting support plate to move through a transmission device, the connecting support plate drives the SUMMA can to move, and drives the air inlet and outlet straight pipe to move downward through a lifting device. After the air inlet and outlet straight pipe is connected to the gas path connecting component, the inside of the SUMMA can is cyclically evacuated and filled with cleaning gas to realize the cleaning of the inside of the SUMMA can. After the cleaning is completed, the lifting device drives the air inlet and outlet straight pipe to move upward, and the air inlet and outlet straight pipe is separated from the gas path connecting component. The transmission device moves the next SUMMA can with the gas path connecting component to the lower part of the air inlet and outlet straight pipe, so as to complete the internal cleaning of multiple SUMMA cans. The structure of the tank cleaning instrument for the SUMMA can is exquisitely designed, realizing the cleaning work of multiple SUMMA cans at one time, reducing the labor intensity of the operator, and having high cleaning stability for the SUMMA can.

[0091] As Figures 10 to 12 shown, the sliding seat 208 includes a clamping groove block 2081.

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 with the annular guide rail 203. The other side of the clamping groove block 2081 corresponding to the bearing mounting plate 2082 is fixedly connected with a clamping pin 2084, and the clamping pin 2084 is fixedly connected with the transmission belt 206. In this embodiment, four bearing pulleys 2083 are arranged at the bottom of the bearing mounting plate 2082. As Figure 13 shown, the connecting support plate 300 is fixedly arranged on the upper part of the bearing mounting plate 2082.

When the air inlet and outlet straight pipe 704 moves downward and is connected to the gas path connecting component 800, the lifting driving component 602 stops operating, and the internal cleaning process of the SUMMA can 500 is carried out. After the cleaning is completed, the lifting driving component 602 drives the connecting block 603 to move upward, and the air inlet and outlet straight pipe 704 is disconnected from the gas path connecting component 800.

[0094] The air inlet and outlet straight pipe 704 is a hard pipe and can be connected to the gas path connecting component 800; the gas filling pipe 702 and the air extraction pipe 703 are flexible pipes, and the gas filling pipe 702 and the air extraction pipe 703 move along with the connecting block 603.

[0095] An adsorption filter (not shown in the figure) is provided on the suction pipe 703, and the adsorption filter communicates with the inside of the suction pipe 703. After the organic pollutants and water vapor extracted from the SUMMA can 500 are absorbed by the adsorption filter, they become clean gas and are discharged from the vacuum pump. While cleaning the SUMMA can 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 SUMMA can 500 and affecting their health.

[0096] It also includes a controller 900 provided inside the frame 100, a touch screen bracket 1000 fixed on one side of the frame 100, and a touch screen 1100. As Figure 1 and Figure 4 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 respectively electrically connected to the controller 900. Cleaning control conditions such as the pressure of the cleaning gas charged into the cleaning gas tank, the speed of the cleaning gas, the pressure of the vacuum, the speed of evacuating the vacuum, and the number of cleaning gas-vacuum evacuation cycles can be input on the touch screen 1100.

[0097] It also includes: a positioning block 1200 fixed on the outer end face of the connection support plate 300 and a positioning detection sensor 1300 fixed on the lifting component bracket 601. As Figure 2 shown. The positioning detection sensor 1300 is electrically connected to the controller 900. When the positioning detection sensor 1300 detects a positioning block 1200 outside one connection support plate 300, at this time, the gas path connection component 800 at the top of the SUMMA can 500 on the connection support plate is aligned with the air inlet and outlet straight pipe 704 up and down, ensuring that the lifting device 600 drives the air inlet and outlet straight pipe 704 to be accurately connected to the gas path connection component 800.

[0098] It also includes a pressure sensor 1500 provided on the air inlet and outlet straight pipe 704. As Figure 5 shown. The pressure sensor 1500 is electrically connected to the controller 900. The pressure sensor 1500 is used to detect the pressure of the cleaning gas charged into the SUMMA can 500 and the vacuum pressure inside the SUMMA can 500 during vacuum evacuation.

[0099] The transmission device 200 drives the connecting support plate 300 to move, thereby driving the Summa can 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 when the lifting device 600 drives the air inlet and outlet straight pipe 704 to descend, the air inlet interface is accurately connected to the air outlet interface, realizing the automatic control of the Summa can cleaning instrument. After one Summa can 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 the next Summa can 500 is cleaned.

[0100] It further includes a scanner 1400 fixedly arranged on the lifting component bracket 601 and electrically connected to the controller 900, as Figure 2 shown. When the positioning detection sensor 1300 detects the positioning block 1200, the scanner 1400 identifies the ID code on the Summa can 500 at the cleaning position and transmits the information of the Summa can 500 to the controller 900, which is displayed and stored on the touch screen 1100, realizing the intelligent recording of the Summa can cleaning instrument and reducing the work intensity of the operator.

[0101] The cleaning instrument for the Summa can can realize automatic and intelligent use, achieve precise control of the cleaning process, and avoid waste of cleaning gas.

[0102] The embodiment of the present utility model provides an air inlet and outlet straight pipe 704 and an air path connection component 800, specifically as follows:

[0103] The inside of the air inlet and outlet straight pipe 704 is a straight pipe channel 7041, and at least one air hole 7042 is arranged along the circumference at the bottom end of the air inlet and outlet straight pipe 704, as Figure 19 and Figure 20 shown.

[0104] As Figures 21 to 26 shown, the air path connection component 800 includes a cylindrical joint body 801. The upper end of the joint body 801 is a straight pipe connection end 802; the lower end of the joint body 801 is a Summa can connection end 803. An inner connecting piece lower end channel 804 is arranged axially in the Summa can connection end 803, and the end of the Summa can connection end 803 is detachably connected to the gas sampling port 501 of the Summa can 500.

[0105] The inner part of the straight pipe connection end 802 is provided with a cylindrical groove 805. Along the circumferential direction inside the cylindrical groove 805, a first annular groove 806 and a second annular groove 807 which are axially spaced are provided. A first sealing washer 808 and a second sealing washer 809 are respectively arranged in the first annular groove 806 and the second annular groove 807. Since the first sealing washer 808 and the second sealing washer 809 are respectively sleeved on the first annular groove 806 and the second annular groove 807, the detachment of the first sealing washer 808 and the second sealing washer 809 is avoided, and finally the sealing effect is better. The space of the cylindrical groove 805 between the first sealing washer 808 and the second sealing washer 809 forms a buffer zone 810; when the air inlet and outlet straight pipe 704 is connected with the air path connecting component 800, the air inlet and outlet straight pipe 704 is movably sleeved in the first sealing washer 808 and the second sealing washer 809, so as to avoid external gas from entering the internal space during the connection process and causing gas pollution.

[0106] A limiting cylinder 811 which coincides with the central axis of the cylindrical groove 805 is arranged in the cylindrical groove 805. The structure of the limiting cylinder 811 is as Figures 27 to 29 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 which communicates with the lower end channel 804 of the connecting piece is formed between the outer side of the limiting cylinder 811 and the inner wall of the joint body 801. An activity column 815 is arranged in the inner cavity of the limiting cylinder 811. The central axis of the activity column 815 coincides with the central axis of the limiting cylinder 811, and the activity column 815 can move up and down along the central axis direction in the inner cavity of the limiting cylinder 811.

[0107] The top end of the activity column 815 is connected with a frustum seat 817. The central axes of the frustum seat 817 and the activity column 815 coincide, as Figure 30 shown. The connection mode between the frustum seat 817 and the activity column 815 is slot clamping or threaded connection or bonding or integral molding. The diameter of the upper bottom surface of the frustum seat 817 is smaller than the diameter of the lower bottom surface. The diameter of the lower bottom surface of the frustum seat 817 is larger than the diameter of the activity column 815, and the lower bottom surface of the frustum seat 817 is connected with the activity column 815. The diameter of the lower bottom surface of the frustum seat 817 is larger than the inner diameter of the limiting cylinder 811, and the frustum seat 817 moves between the limiting cylinder 811 and the second sealing washer 809. The diameter of the upper bottom surface of the frustum seat 817 is larger than the inner diameter of the air inlet and outlet straight pipe 704, and the bottom port of the air inlet and outlet straight pipe 704 is movably connected with the upper bottom surface of the frustum seat 817. During the process of inflating the inside of the Summa can 500, when the bottom port of the air inlet and outlet straight pipe 704 contacts the upper bottom surface of the frustum seat 817, the gas in the straight pipe channel 7041 can flow out from the air holes 7042 of the air inlet and outlet straight pipe 704 to the internal air flow channel 812.

[0108] As Figure 24As shown, a spring 816 is arranged in the inner cavity of the limit cylinder 811. One end of the spring 816 is fixed at the middle position of the bottom surface of the inner cavity of the limit cylinder 811. The fixing method can be bonding or clamping. The other end of the spring 816 abuts against the bottom surface of the movable column 815.

[0109] While playing a sealing role, the second sealing washer 809 and the limit cylinder 811 play a role in limiting the moving positions at both ends of the movement of the frustum seat 817.

[0110] A positioning support 818 is fixedly arranged on the lower end surface of the limit cylinder 811, so that the central axis of the limit cylinder 811 coincides with the central axis of the cylindrical groove 805, and at the same time, it is ensured that the internal air flow channel 812 communicates with the lower end channel 804 of the connecting piece. The fixing method is bonding, clamping or thread connection.

[0111] The combined structure of the first annular groove 806, the second annular groove 807 and the corresponding first sealing washer 808 and second sealing washer 809 ensures the sealing effect of the internal space during the connection process, ventilation process and separation process of the air inlet and outlet straight pipe 704 and the air path connecting component 800, and avoids the entry of external gas into the internal space and affecting the purity of the internal flowing gas.

[0112] The setting of the spring 816 in the limit cylinder 811 can realize the automatic reset of the frustum seat 817, making it more convenient to use; at the same time, it avoids the entry of external gas into the internal space of the air path connecting component 800 during the process of the air inlet and outlet straight pipe 704 moving out of the air path connecting component 800 and affecting the purity of the next incoming gas.

[0113] A preferred embodiment of the present utility model: A third annular groove 813 is opened along the circumferential direction near the opening position of the inner cavity of the limit cylinder 811. A third sealing washer 814 is arranged in the third annular groove 813. The movable column 815 is sleeved in the third sealing washer 814, and the movable column 815 can slide in the third sealing washer 814.

[0114] By arranging the third sealing washer 814 at the opening position of the limit cylinder 811, it avoids the closed space that is prone to storing gas formed inside the limit cylinder 811 due to the up and down movement of the movable column 815 in the limit cylinder 811, and thus avoids gas pollution.

[0115] Another preferred embodiment of the present utility model: The structure of the positioning support 818 is as Figure 31 and Figure 32As shown, the positioning support member 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 symmetric support arms 8182 are provided. The positioning rod 8181 is stuck in the lower channel 804 of the connecting member, playing a role in positioning and limiting to make the central axis of the limiting cylinder 811 coincide 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, playing a role in supporting the limiting cylinder 811. The positioning rod 8181 does not completely contact the side wall of the lower channel 804 of the connecting member, and the positioning rod 8181 partially fits with the side wall of the lower channel 804 of the connecting member, ensuring that the internal air flow channel 812 communicates with the lower channel 804 of the connecting member.

[0116] Further, in order to meet the requirement that a large flow of gas passes through the space between the internal air flow channel 812 and the lower channel 804 of the connecting member, the positioning support member 818 is of a shell structure, forming a positioning support member cavity 8183, as Figure 33 shown. When filling the cleaning gas into the SUMMA can 500, part of the air flow enters the lower channel 804 of the connecting member from the internal air flow channel 812, and another part of the air flow flows from the outside of the positioning support member 818 to the lower channel 804 of the connecting member.

[0117] The first sealing washer 808, the second sealing washer 809 and the third sealing washer 814 are made of silicone rubber material, which deforms under extrusion and returns to its original state after the external force is removed, ensuring the sealing effect.

[0118] The gas path connection component and the air inlet and outlet straight pipe provided by the embodiment of the present utility model simplify the connection mode between the two. Compared with the traditional connection mode, the gas path connection component and the air inlet and outlet straight pipe can not only reduce the connection time and labor cost, but also ensure the sealing performance during the connection process, the intermediate process and the disconnection process.

[0119] The working principle of the air inlet and outlet straight pipe 704 and the gas path connection component 800:

[0120] During the process of inserting the air inlet / outlet straight pipe 704 into the gas path connection component 800, the central axes of the gas path connection component 800 and the air inlet / 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 / outlet straight pipe 704. The air hole 7042 of the air inlet / outlet straight pipe 704 passes through the buffer zone 810 between the first sealing gasket 808 and the second sealing gasket 809. After the bottom port of the air inlet / outlet straight pipe 704 contacts the upper bottom surface of the frustum seat 817, the air inlet / outlet straight pipe 704 further pushes the frustum seat 817 to move towards the limit cylinder 811, and the spring 816 is compressed by the movable column 815. The bottom air hole 7042 of the air inlet / outlet straight pipe 704 further moves downward towards the cylindrical groove 805 after passing through the buffer zone 810. When the lower bottom surface of the frustum seat 817 abuts against the open end of the limit cylinder 811, the frustum seat 817 stops moving. At this time, the air hole 7042 moves into the internal space below the second sealing gasket 809, as Figures 16 to 18 shown. When filling the cleaning gas into the inside of the Summa can 500, the cleaning gas flows from the straight pipe channel 7041 to the air hole 7042 and then into the internal space, and flows through the internal air flow channel 812 to the lower channel 804 of the connector, and flows out of the gas path connection component 800 into the Summa can 500. During the vacuum pumping process, the air flow direction is opposite to the air flow direction when filling the cleaning gas, and the connection state of the air inlet / outlet straight pipe 704 and the gas path connection component 800 and the internal structure of the gas path connection component 800 remain unchanged.

[0121] When the movable column 815 loses the pressure of the air inlet / outlet straight pipe 704, the bottom end of the air inlet / outlet straight pipe 704 moves towards the upper end of the joint body 801, the spring 816 rebounds, the air inlet / outlet straight pipe 704 and the frustum seat 817 move synchronously. After the side surface of the frustum seat 817 abuts against the second sealing gasket 809, the air inlet / outlet straight pipe 704 is separated from the frustum seat 817, and then the air inlet / outlet straight pipe 704 is removed from the gas path connection component 800. In this way, the automatic reset of the frustum seat 817 can be realized, which is more convenient to use. At the same time, it avoids the entry of external gas into the internal space of the gas path connection component 800 during the process of removing the air inlet / outlet straight pipe 704 from the gas path connection component 800, affecting the purity of the gas when the air inlet / outlet straight pipe 704 and the gas path connection component 800 are connected next time.

[0122] The embodiment of the present utility model also provides a method for using the can cleaning instrument of the above-mentioned Summa can, including the following steps:

[0123] S1. Connect the lower port of the Summa can connection end 803 of the gas path connection component 800 to the gas sampling port 501 of the Summa can 500;

[0125] S3. The transmission device 200 rotates to drive the Summa canister 500 to move at equal intervals;

[0126] S4. The air inlet and outlet straight pipe 704 is aligned with the gas path connection component 800 above a Summa canister 500, and the transmission device 200 is stopped; the lifting device 600 operates to cause the connection block 603 to 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 to the gas path connection component 800;

[0127] S5. 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 Summa canister 500 is pumped out; after reaching the set vacuum 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 to fill the gas inside the cleaning gas tank into the Summa canister 500;

[0128] S6. Repeat step S5 to cycle through the process of vacuum pumping - filling with cleaning gas;

[0129] S7. After the inside of the Summa canister 500 is cleaned, the lifting device 600 controls the connection block 603 to move upward, driving the air inlet and outlet straight pipe 704 to move upward, and the air inlet and outlet straight pipe 704 is separated from the gas path connection component 800;

[0130] S8. Repeat the process of S3 - S7 to complete the cleaning of multiple Summa canisters 500.
