Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning device for sampling tanks. Background Technology

[0002] Volatile organic compounds (VOCs) are a major concern in environmental monitoring, and their accurate measurement is crucial for assessing air quality and controlling environmental pollution. Summa canisters, as specialized equipment for collecting and storing VOC gases, are widely used in sampling ambient air and industrial waste gases due to their excellent sealing and low adsorption properties. After sampling, various complex pollutants remain inside the canister, requiring thorough cleaning. While existing cleaning devices for sampling canisters generally meet daily usage needs, some shortcomings still require improvement.

[0003] Currently, the working principle of widely used automatic tank cleaning devices mainly involves the combined action of high-pressure spray cleaning fluid, vacuuming, and inert gas replacement to clean the inside of the SUMMA tank. However, in actual operation, during the installation of the SUMMA tank, operators need to tightly install the tank onto specific connecting ports inside the equipment to ensure the automatic tank cleaning device functions properly and thoroughly cleans the tank's interior. This installation process presents several inconveniences. Firstly, aligning the SUMMA tank's interface with the equipment's connecting port requires manual operation. Operators must continuously adjust the tank's position to achieve precise alignment, a process that is not only time-consuming and labor-intensive but also demands a high level of experience and skill from the operator, making installation challenging. Secondly, during manual support and positional correction of the SUMMA tank, the risk of accidental drop cannot be completely avoided. If the tank falls, it may damage the tank itself, affecting its subsequent normal use. Therefore, we propose a cleaning device for sampling tanks to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment sedimentation tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for a sampling tank, comprising an automatic tank cleaner, a connecting pipe port located at the bottom of the automatic tank cleaner, a control panel fixed to the outer wall of the left end of the automatic tank cleaner, and buttons located on the control panel. The automatic tank cleaner contains a Summa tank. A threaded sleeve is located at the center of the top of the automatic tank cleaner. A lead screw is threadedly connected to the threaded sleeve. A lifting plate is rotatably connected to the bottom end of the lead screw. A rotating ring is installed at the top end of the lead screw. A guide groove is located at the front end of the threaded sleeve. A guide rod is located within the guide groove. The bottom end of the guide rod is fixed to the outer wall of the top end of the lifting plate. Slide rails are fixed on both sides of the bottom end of the lifting plate. A sleeve is located below the lifting plate. Slider blocks are fixed on both sides of the sleeve. Two sets of sliders are located inside the two sets of slide rails. A fixing plate is installed at the top of the Summa tank. The fixing plate can be inserted into the sleeve. A horizontal pull handle is installed at the front end of each set of sliders via a connecting rod. A first return spring is wound around the outside of each set of connecting rods. A locking component is located at the front end of the sleeve.

[0006] As an improved technical solution, the locking assembly includes a movable inner cavity, a slide rod, a positioning block, a sliding sleeve, a pull rod, and a second return spring. The movable inner cavity is provided on the right side of the front end of the sleeve. Slide rods are installed on both the front and rear sides of the movable inner cavity. A positioning block is provided inside the movable inner cavity. Slide sleeves are installed on both the front and rear sides of the right end of the positioning block. Both sets of sliding sleeves are located outside the slide rods. The left end of the positioning block can enter the sleeve. A pull rod is installed on the right end of the positioning block. The second return spring is wound around the outside of both sets of slide rods.

[0007] As an improved technical solution, the interface, connecting pipe, and lead screw at the bottom of the Suma can are located on the same central axis.

[0008] As an improved technical solution, the outer wall of the rotating ring is provided with anti-slip texture.

[0009] As an improved technical solution, the inner diameter of the sliding sleeve is the same as the outer diameter of the sliding rod, and the sliding sleeve and the sliding rod form a sliding connection.

[0010] As an improved technical solution, the outer wall of the left rear end of the positioning block can be fitted with the outer wall of the front end of the fixing plate that enters the sleeve.

[0011] As an improved technical solution, the two ends of the second reset spring are respectively connected to the outer wall of the positioning block and the inner wall of the movable inner cavity, and the positioning block is elastically connected to the inner wall of the movable inner cavity through two sets of second reset springs.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] I. This utility model features an automatically adjustable lifting plate installed inside the automatic tank cleaning device, with a movable sleeve at the bottom of the lifting plate. The external fixing plate of the Suma can is inserted into the sleeve, allowing the sleeve to lift and move the entire Suma can, ensuring the bottom interface of the Suma can is accurately moved above the connecting pipe opening. Then, by rotating the rotating ring, the lifting plate, under the action of the lead screw and guide rod, smoothly moves the Suma can up and down, allowing the bottom interface of the Suma can to smoothly connect with the connecting pipe opening. This enables the automatic tank cleaning device to thoroughly clean the inside of the Suma can. The entire installation process eliminates the need for continuous manual support of the Suma can, thus reducing the difficulty of installation and improving the convenience of use.

[0014] II. This utility model has a laterally movable positioning block installed at the front end of the sleeve. When the fixing plate is placed inside the sleeve, the fixing plate is pushed to the limit inside the sleeve, and the positioning block is inserted into the sleeve. The positioning block quickly forms a stable movement limit on the fixing plate inside the sleeve, preventing the Suma can from shaking and falling accidentally when it is moved, thus ensuring the stability of the Suma can during installation.

[0028] Figures 1 to 7As shown, this embodiment provides a cleaning device for sampling tanks, including an automatic tank cleaner 1, a connecting pipe port 2 located at the bottom of the automatic tank cleaner 1, a control panel 6 fixed to the outer wall of the left end of the automatic tank cleaner 1, and buttons 7 located on the control panel 6. A Summa tank 3 is installed inside the automatic tank cleaner 1. A threaded sleeve 9 is located at the center of the top of the automatic tank cleaner 1. A lead screw 10 is threadedly connected to the threaded sleeve 9. A lifting plate 8 is rotatably connected to the bottom of the lead screw 10. A rotating ring 11 is installed at the top of the lead screw 10. A guide groove 13 is provided at the front end of the threaded sleeve 9. A guide rod 12 is provided inside the 13. The bottom end of the guide rod 12 is fixed to the outer wall of the top of the lifting plate 8. Slide rails 14 are fixed on both sides of the bottom end of the lifting plate 8. A sleeve 5 is provided below the lifting plate 8. Slider 15 is fixed on both sides of the sleeve 5. Both sets of sliders 15 are located inside the two sets of slide rails 14. A fixing plate 4 is installed at the top of the Suma can 3. The fixing plate 4 can be inserted into the sleeve 5. A horizontal pull handle 17 is installed at the front end of both sets of sliders 15 through a connecting rod 16. A first return spring 18 is wound around the outside of both sets of connecting rods 16. A locking component is provided at the front end of the sleeve 5.

[0029] By installing a liftable lifting plate 8 inside the automatic tank cleaner 1, and installing a movable sleeve 5 at the bottom of the lifting plate 8, the fixing plate 4 of the outside of the Suma can 3 can be inserted into the sleeve 5, allowing the sleeve 5 to lift and move the Suma can 3 as a whole, so that the interface at the bottom of the Suma can 3 can be accurately moved above the connecting pipe port 2. Then, by rotating the rotating ring 11, the lifting plate 8 can drive the Suma can 3 to move up and down smoothly under the action of the screw 10 and the guide rod 12, so that the interface at the bottom of the Suma can 3 can be smoothly connected with the connecting pipe port 2, allowing the automatic tank cleaner 1 to thoroughly clean the inside of the Suma can 3. This eliminates the need for continuous manual support of the Suma can 3 during the entire installation process, thereby reducing the difficulty of installing the Suma can 3 and improving the convenience of using the device.

[0030] In other embodiments, the locking assembly includes a movable inner cavity 19, a slide bar 20, a positioning block 21, a sliding sleeve 22, a pull rod 23, and a second return spring 24. The movable inner cavity 19 is provided on the right side of the front end of the sleeve 5. Slide bars 20 are installed on both the front and rear sides of the movable inner cavity 19. A positioning block 21 is provided inside the movable inner cavity 19. Slide sleeves 22 are installed on both the front and rear sides of the right end of the positioning block 21. Both sets of sliding sleeves 22 are located outside the slide bar 20. The left end of the positioning block 21 can enter the sleeve 5. A pull rod 23 is installed on the right end of the positioning block 21. The second return spring 24 is wound around the outside of the two sets of slide bars 20.

[0031] By installing a laterally movable positioning block 21 at the front end of the sleeve 5, when the fixing plate 4 is placed inside the sleeve 5, the fixing plate 4 is pushed to the limit inside the sleeve 5, and the positioning block 21 is inserted into the sleeve 5. The positioning block 21 quickly forms a stable movable limit on the fixing plate 4 inside the sleeve 5, preventing the Suma can 3 from shaking when it moves, thus ensuring the stability of the Suma can 3 during installation.

[0032] In other embodiments, the interface at the bottom of the Summa can 3, the connecting pipe 2, and the lead screw 10 are located on the same central axis;

[0033] With this design, when the lead screw 10 rotates and the lifting plate 8 descends, the lifting plate 8 can drive the bottom interface of the Suma can 3 to descend to the connecting pipe port 2, ensuring that the bottom interface of the Suma can 3 can be smoothly connected with the connecting pipe port 2.

[0034] In other embodiments, the outer wall of the rotating ring 11 is provided with anti-slip texture;

[0035] This design effectively increases the friction between the rotating ring 11 and the user's hand when the hand holds the rotating ring 11 and applies a rotational force to it, thereby preventing the rotating ring 11 from accidentally slipping out of the hand while rotating.

[0036] In other embodiments, the inner diameter of the sliding sleeve 22 is the same as the outer diameter of the sliding rod 20, and the sliding sleeve 22 and the sliding rod 20 form a sliding connection;

[0037] With this design, when the positioning block 21 drives the two sets of sliding sleeves 22 to move along the outside of the two sets of sliding rods 20, it can effectively prevent the positioning block 21 from shaking during the movement, thereby improving the stability of the positioning block 21 during installation.

[0038] In other embodiments, the outer wall of the left rear end of the positioning block 21 can be fitted with the outer wall of the front end of the fixing plate 4 that enters the sleeve 5;

[0039] With this design, when the fixing plate 4 is inserted into the sleeve 5 and pushed to move along the inside of the sleeve 5 to the limit, the positioning block 21 can then extend out from the movable inner cavity 19, so that the positioning block 21 can form a stable movable limit effect on the fixing plate 4.

[0040] In other embodiments, the two ends of the second return spring 24 are respectively connected to the outer wall of the positioning block 21 and the inner wall of the movable inner cavity 19, and the positioning block 21 is elastically connected to the inner wall of the movable inner cavity 19 through two sets of second return springs 24;

[0041] This design allows the second return spring 24 outside the two sets of slide rods 20 to continuously apply a leftward elastic force to the slide sleeve 22, enabling the two sets of slide sleeves 22 to drive the positioning block 21 to quickly insert into the sleeve 5.

[0042] The automatic tank cleaner 1 uses a BCT930 tank cleaner, which can perform humidification cleaning and heating cleaning. The maximum temperature can be set to 200℃. It can fill the Suma tank 3 with high-purity nitrogen or zero air and repeatedly perform the filling and evacuation cycle. Through multiple cycles, the residual impurities in the tank are carried out, thereby achieving the cleaning purpose.

[0043] This utility model provides a cleaning device for sampling tanks, the specific working principle of which is as follows:

[0044] When using this equipment, first pull the horizontal handle 17 towards the front end, causing the horizontal handle 17 to drive the two sets of sliders 15 and the sleeve 5 to move towards the front end along the two sets of slide rails 14 at the bottom of the lifting plate 8. During the movement of the sliders 15, the first return spring 18 outside the connecting rod 16 is squeezed, causing the first return spring 18 to contract and store force. When the sleeve 5 moves to the front end, then pull the lever 23 to the right end, causing the positioning block 21 to drive the two sets of sliding sleeves 22 to move towards the right end along the two sets of sliding rods 20, and causing the two sets of sliding sleeves 22 to squeeze the second return springs 24 outside the two sets of sliding rods 20. When the positioning block 21 is fully retracted into the movable inner cavity 19, the fixing plate 4 on the Suma can 3 can be inserted into the sleeve 5 and the fixing plate 4 can be pushed into the sleeve 5 to the inner limit. Then release the tension on the lever 23, causing the second return springs 24 outside the two sets of sliding rods 20 to release their elasticity and push the sliding sleeves 22 to the left end, allowing the two sets of sliding sleeves 22 to move towards the right end. The sliding sleeve 22 can drive the positioning block 21 to move to the left, so that the positioning block 21 forms a movable limit on the fixed plate 4 inside the sleeve 5. Then, the tension on the horizontal pull handle 17 is released, so that the first return spring 18 outside the two sets of connecting rods 16 releases its elasticity and pushes the two sets of sliders 15 to move to the rear end. The two sets of sliders 15 drive the sleeve 5 to move along the slide rail 14 to the limit, so that the sleeve 5 can move the Suma can 3 to the top of the connecting pipe port 2. Then, the rotating ring 11 can be grasped and a rotational force can be applied to the rotating ring 11, so that the lead screw 10 rotates in the threaded sleeve 9. This allows the lifting plate 8 to move smoothly downward under the guidance of the thread of the lead screw 10 and the guide rod 12, so that the interface at the bottom of the Suma can 3 can move closer to the connecting pipe port 2, thereby facilitating the quick docking of the connecting pipe port 2 and the Suma can 3 for a tight connection. Then, the automatic can cleaning device 1 can be started to flush the inside of the Suma can 3 through the connecting pipe port 2. The operation is then completed.

[0045] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
