Description

Technical Field

[0001] The present invention relates to the technical field of tank filling, and particularly relates to a multi-station filling cabinet. Background Art

[0002] The filling cabinet is a constant temperature device. However, during the filling of the tank in the filling cabinet, it is often necessary to repeatedly sample and inspect the composition and quality of the filling gas and liquid. This requires manual opening of the cabinet door and manual opening and closing of the valves of the tank, inevitably causing temperature loss. In the prior art, a filling cabinet has multiple tank stations, which may require manual repeated opening and closing of the tank valves. This is repetitive and cumbersome for workers, and once there is a leakage of gas or liquid, the danger is relatively high. Secondly, repeatedly opening and closing the filling cabinet door causes serious temperature loss, resulting in waste of resources and affecting the quality of gas and liquid filling. In addition, the filling cabinet equipment requires manual handling of the tank into the cabinet and loading and unloading of the tank at the upper and lower positions on both sides of the channel. However, due to considerations of space utilization, the channel is often set to be relatively compact, making it inconvenient to operate the upper and lower tanks. Moreover, the filling cabinet needs to be insulated in the range of -20°C to 60°C, and the temperature environment is relatively harsh. Summary of the Invention

[0074] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further elaborate on the present invention.

[0075] First, in combination with Figures 1 to 15 A multi-station filling cabinet according to an embodiment of the present invention will be described, which is used for gas-liquid filling of a tank body and has a wide range of application scenarios.

[0076] As Figures 1 to 15 shown, the multi-station filling cabinet of the embodiment of the present invention includes: a cabinet body 1, a pair of sliding door modules 2, a temperature control module 3, a plurality of tank body positioning modules 4, and an opening and closing valve module 5. In this embodiment, the cabinet body 1 is a cuboid frame, and its top surface, bottom surface, and both end surfaces are sealed by heat preservation plates 12. The heat preservation plates 12 are hermetically lapped with the cabinet body 1, and foaming glue is applied at the gaps to ensure the overall equipment is sealed and heat-insulated, reducing heat loss; the heat preservation plates 12 are made of polyurethane composite plates, which have good heat preservation, heat insulation, and sound insulation effects; in this embodiment, the cabinet body 1 is provided with lifting lugs 11 at the top for convenient transportation.

[0077] Specifically, as Figures 1 to 2As shown, in this embodiment, a pair of sliding door modules 2 are respectively arranged on two side surfaces of the cabinet body 1 and can slide along the length direction of the cabinet body 1. The sliding door modules 2 are used for sealing the side surfaces of the cabinet body 1. When personnel perform operations on the upper and lower tanks inward from the outside of the filling cabinet, they only need to open the sliding doors at the corresponding workstations. The operation time for the upper and lower tanks is short, reducing the discomfort caused to workers by the overcooled or overheated temperature inside the cabinet. At the same time, the temperature change caused by the upper and lower tank operations is reduced, improving the filling quality. The temperature control module 3 is arranged on the cabinet body 1 and is connected to the inside of the cabinet body 1. The temperature control module 3 regulates the temperature inside the cabinet body 1. A plurality of tank positioning modules 4 are arranged inside the cabinet body 1 and are arranged along the length direction of the cabinet body 1. The tank positioning modules 4 are used to position and fix the tanks. The tank positioning modules 4 have open ends for placing the tanks. In this embodiment, a plurality of tank positioning modules 4 are arranged in two rows in mirror symmetry, and the open ends of the adjacent row of tank positioning modules 4 face in opposite directions, saving space and improving space utilization. The opening and closing valve module 5 is arranged inside the cabinet body 1 and is adjacent to the tank positioning module 4. The opening and closing valve module 5 automatically screws the valves of the tanks to open and close the valves. Through the opening and closing valve module 5 and the tank positioning module 4, remote automatic opening and closing valve operations are realized during the tank filling operation, without manual intervention, reducing the manual labor intensity and the discomfort of the temperature inside the cabinet body 1.

[0078] Specifically, as Figures 2 to 3 shown, in this embodiment, the tank positioning module 4 includes: a frame 41, a U-shaped ventilation plate 42 and a fixing mechanism; the frame 41 is fixed inside the cabinet body 1; in this embodiment, the U-shaped ventilation plate 42 is a U-shaped plate with a plurality of air holes opened. The air holes can directly blow the cold air or hot air output by the temperature control module 3 onto the surface of the tank, thereby realizing the cooling or heating operation of the tank. The U-shaped setting is adopted, and a horseshoe-shaped air duct is formed inside, improving the air circulation efficiency; the U-shaped ventilation plate 42 is vertically fixed on the frame 41, and the opening of the U-shaped ventilation plate 42 faces the outside of the cabinet body 1. The opening of the U-shaped ventilation plate 42 is used to place the tank; the fixing mechanism is arranged at both ends of the U-shaped ventilation plate 42 and inside the U-shaped ventilation plate 42, and the fixing mechanism clamps and fixes the tank. In this embodiment, a filling pipeline 6 and a filling joint 61 are fixed on the frame 41. The filling pipeline 6 connects the gas-liquid source and the filling joint 61. Each U-shaped ventilation plate 42 is correspondingly provided with a filling joint 61, and the filling joint 61 is connected to the filling port of the tank for gas-liquid filling. Two tank positioning modules 4 that are in mirror symmetry share one frame 41, saving cost and space, ensuring the relative position, and improving the positioning accuracy.

[0079] Furthermore, as Figure 3As shown in the figure, in this embodiment, the fixing mechanism includes: a pair of fixing cylinders 43, a pair of mounting blocks 44, a plurality of positioning blocks 45, a movable door frame 46, and a door lock 47; the pair of fixing cylinders 43 are respectively fixed at both ends of the opening of the U-shaped ventilation plate 42; the pair of mounting blocks 44 are respectively connected to the output ends of the pair of fixing cylinders 43, and the door lock 47 is arranged on one of the mounting blocks 44; one end of the movable door frame 46 is provided with a lock hole, and the lock hole cooperates with the lock tongue of the door lock 47 to fix the movable door frame 46, and the other end of the movable door frame 46 is hinged to the other mounting block 44 through a hinge, so that the movable door frame 46 can rotate around the mounting block 44 to open or close the movable door frame 46; the positioning block 45 is provided with a V-shaped opening, and a plurality of positioning blocks 45 are respectively fixed inside the movable door frame 46 and the U-shaped ventilation plate 42, and the openings of the positioning blocks 45 arranged on the movable door frame 46 and the U-shaped ventilation plate 42 are opposite; the fixing cylinder 43 drives the movable door frame 46 to move closer to the U-shaped ventilation plate 42, driving the positioning block 45 on the movable door frame 46 to approach the positioning block 45 on the U-shaped ventilation plate 42, so as to clamp and position the tank body. In this embodiment, the positioning block 45 is made of nylon material, which can not only ensure the strength required for centering the tank body, but also will not scratch the surface of the tank body.

[0080] In this embodiment, when a new tank body needs to be installed, the operator manually opens the door lock 47 to open the movable door frame 46, brings the tank body to be filled close to the positioning block 45 on the U-shaped ventilation plate 42 for initial positioning, closes the movable door frame 46, and locks the door lock 47; when the opening and closing valve operation is required, the pair of fixing cylinders 43 act simultaneously, driving the positioning block 45 on the movable door frame 46 to drive the tank body towards the positioning block 45 on the U-shaped ventilation plate 42. Under the clamping action of the positioning blocks 45 on both sides, the tank body will move to the set displacement center position, which is also the working position of the opening and closing valve module 5. The positioning blocks 45 on both sides will clamp the tank body to prevent the tank body from rotating and moving, so as to accurately perform the opening and closing valve operation of the tank body. The positioning block 45 and the movable door frame 46 can also prevent the tank body from tipping over in case of an accident, causing a safety accident.

[0081] Furthermore, as Figure 3 shown in the figure, in this embodiment, the tank body positioning module 4 further includes: a pushing cylinder 48 and an electronic scale 49; the electronic scale 49 is arranged at the bottom of the cabinet body 1; the pushing cylinder 48 is arranged on the frame 41, and the output end of the pushing cylinder 48 can extend into the U-shaped ventilation plate 42 to push the tank body onto the electronic scale 49 for weighing.

[0082] When the tank body needs to continue the filling operation, the pair of fixing cylinders 43 extend simultaneously, driving the positioning block 45 on the movable door frame 46 away from the tank body, and the pushing cylinder 48 acts to push the tank body out so that it does not contact the positioning block 45 on the U-shaped ventilation plate 42 and the positioning block 45 on the movable door frame 46, thus ensuring the accurate detection of the weight of the tank body by the electronic scale 49.

[0083] Specifically, as Figures 4 to 10 shown, in this embodiment, the opening and closing valve module 5 includes: a lateral movement module 51, a longitudinal movement mechanism, and a rotating mechanism; the lateral movement module 51 is disposed in the cabinet 1 along the length direction of the cabinet 1; the longitudinal movement mechanism is disposed at the output end of the lateral movement module 51, and the rotating mechanism is disposed at the output end of the longitudinal movement mechanism; the lateral movement module 51 drives the longitudinal movement mechanism to move along the length direction of the cabinet 1, and the longitudinal movement mechanism drives the rotating mechanism to move in the vertical direction, and the rotating mechanism sleeved on the valve of the tank body and screwing, driving the valve to open and close. In this embodiment, the lateral movement module 51 can adopt a linear guide rail module, a synchronous belt module, a gear rack module, etc., and the lateral movement module 51 and the longitudinal movement mechanism are used to realize the displacement of the rotating mechanism in two directions.

[0084] Furthermore, as Figure 5 shown, in this embodiment, the longitudinal movement mechanism includes: a mounting plate 521, a cylinder 522, and a guide rail 523; the mounting plate 521 is disposed at the output end of the lateral movement module 51; the cylinder 522 is fixed on the mounting plate 521, and the output end of the cylinder 522 is connected to the rotating mechanism; the guide rail 523 is vertically fixed on the mounting plate 521 and is slidably connected to the rotating mechanism; the cylinder 522 drives the rotating mechanism to slide along the guide rail 523, driving the rotating mechanism to approach or move away from the valve of the tank body.

[0085] Furthermore, as Figure 5 shown, in this embodiment, the rotating mechanism includes: a mounting bracket 531, a driving motor 532, a torque sensor 533, and a flexible fixture 534; the mounting bracket 531 is disposed at the output end of the longitudinal movement mechanism; the driving motor 532 is fixed on the mounting bracket 531; the torque sensor 533 is connected to the output end of the driving motor 532 and the flexible fixture 534, and the flexible fixture 534 clamps the valve of the tank body; the driving motor 532 drives the flexible fixture 534 to rotate, and the torque sensor 533 monitors in real time the rotational torque applied by the driving motor 532 to the flexible fixture 534. In this embodiment, a servo motor is used as the power source, and the torque sensor 533 is used to output the accurate torque required to open and close the valve. The flexible fixture 534 can be compatible with and adapt to the valves of different sizes of the tank body.

[0086] Furthermore, as Figures 5 to 10 shown, in this embodiment, the flexible fixture 534 includes: a mounting seat, a joint 5341 is provided at the top of the mounting seat, and the joint 5341 is connected to the torque sensor 533; a plurality of telescopic sliding rods are slidably disposed in the mounting seat and extend out of the bottom of the mounting seat; when the mounting seat moves axially downward and drives the plurality of telescopic sliding rods to contact the handle of the valve, some of the telescopic sliding rods are compressed against the handle, and the uncompressed telescopic sliding rods are inserted into the handle gap to clamp the handle.

[0087] In this embodiment, the mounting seat includes: a mounting cylinder 5342, an upper mounting plate 5343, a lower mounting plate 5344, an upper sealing seat 5345 and a lower sealing plate 5346; the upper and lower end surfaces of the mounting cylinder 5342 are provided with annular grooves around its inner wall, which are respectively used to place the upper mounting plate 5343 and the lower mounting plate 5344; the upper sealing seat 5345 is connected to the upper end surface of the mounting cylinder 5342 and abuts against the top surface of the upper mounting plate 5343; the lower sealing plate 5346 is connected to the lower end surface of the mounting cylinder 5342 and abuts against the bottom surface of the lower mounting plate 5344; a number of telescopic sliding rods pass through the upper mounting plate 5343 and the lower mounting plate 5344. The mounting seat serves as the main frame and provides installation space. The upper and lower mounting plates 5344 serve as the penetrating support base of the telescopic slide rod. The upper sealing seat 5345 and the lower sealing plate 5346 respectively block the upper and lower ends of the mounting cylinder 5342 and are respectively abutted against the upper and lower mounting plates 5344 for fixation. The split setting facilitates independent replacement or maintenance of each component. Telescopic slide rods of different sizes can be replaced according to the size of the valve handle.

[0088] In this embodiment, the upper mounting plate 5343, the lower mounting plate 5344 and the lower sealing plate 5346 are all annular, so that all telescopic slide rods are distributed around the outer ring of the handle, the torque is greater under the same clamping force, the rotation is easier, and most of the handle centers are solid without gaps, and the annular shape saves more materials. The upper sealing seat 5345 is cylindrical, which is convenient for the telescopic slide rod to be extended. The upper mounting plate 5343 and the lower mounting plate 5344 are both made of wear-resistant plates to resist the friction caused by the frequent sliding of the telescopic slide rod, reduce the wear and deformation of the mounting plate 521, and extend the service life.

[0089] In this embodiment, a plurality of mounting holes are correspondingly provided on the upper mounting plate 5343 and the lower mounting plate 5344. The plurality of mounting holes are respectively used to install a plurality of telescopic slide rods. The mounting holes are used to pass the telescopic slide rods, and the axial movement of the telescopic slide rods is limited by the corresponding upper and lower mounting holes.

[0090] In this embodiment, the outer circumferences of the upper mounting plate 5343 and the lower mounting plate 5344 are provided with a plurality of first arc holes at intervals, and the inner circumferences of the upper and lower ends of the mounting tube 5342 are provided with a plurality of second arc holes at intervals. The plurality of first arc holes are respectively matched with the plurality of second arc holes to form a plurality of circular holes, and a positioning pin is inserted in each circular hole, and the positioning pin is used to position the upper mounting plate 5343 and the lower mounting plate 5344. The first arc holes of the upper / lower mounting plates 5344 and the second arc holes of the mounting tube 5342 are combined to form a complete circular hole. After the positioning pin is inserted, the circumferential angles of the upper and lower mounting plates 5344 and the mounting tube 5342 are ensured to be strictly aligned, which can prevent the mounting plate 521 from rotating relative to the mounting tube 5342 when subjected to force (such as rotational torque, vibration), and the positioning is fast and convenient. The plurality of positioning pins are evenly distributed circumferentially to disperse the shear stress and extend the service life of the structure.

[0091] In this embodiment, the installation cylinder 5342 is connected to the upper sealing seat 5345 and the lower sealing plate 5346 through fixing members. The fixing members can be screws, bolts or pins, which facilitates disassembly and assembly.

[0092] In this embodiment, the telescopic sliding rod includes: a sliding rod 5347, a spring 5348 and a limit ring 5349; the sliding rod 5347 penetrates through the upper mounting plate 5343 and the lower mounting plate 5344; the limit ring 5349 is arranged on the sliding rod 5347 and abuts against the top surface of the lower mounting plate 5344 to limit the maximum extended length of the sliding rod 5347 and prevent it from falling off; the spring 5348 is sleeved on the sliding rod 5347, and the two ends of the spring 5348 respectively abut against the limit ring 5349 and the bottom surface of the upper mounting plate 5343. The elastic deformation of the spring 5348 realizes the telescoping of the sliding rod 5347 and the flexible clamping of the sliding rod 5347 and the handle.

[0093] Under the action of the compressed spring 5348, when the external force axially applied to the sliding rod 5347 is greater than the elastic force of the spring 5348, the spring 5348 is compressed, and the sliding rod 5347 moves synchronously by a corresponding stroke. When the external force disappears, the spring 5348 resumes its telescoping and drives the sliding rod 5347 back to the initial position; when the flexible fixture 534 moves downward in the axial direction of the valve, part of the sliding rod 5347 will be compressed. The uncompressed sliding rod 5347 clamps the edge of the valve handle. When the joint 5341 is connected to a power source and makes a rotational movement, it can drive the uncompressed sliding rod 5347 and the valve handle to rotate synchronously, thereby realizing the opening and closing of the valve.
