Description

Technical Field

[0001] The utility model relates to the technical field of ton barrel exhaust, in particular to an auxiliary exhaust device for a ton barrel. Background Art

[0002] A ton barrel is a container used to store and transport various liquids and granular items. It consists of a barrel body, a barrel cover, a frame, a pallet and other components. When a ton barrel is transporting and storing liquids, pressure will be generated due to the evaporation of the liquid and the change in the gas volume. This pressure may cause the barrel body to deform, rupture, leak and other problems. In order to solve this problem, an exhaust valve will be set on the barrel cover to ensure the pressure coordination of the gas in the barrel. When exhaust is required, the staff will turn the valve handle to keep it level with the valve body. When exhaust is not required, the staff will turn the valve handle to a vertical state with the valve body to achieve the closing of the valve body.

[0003] When the ton barrel is being transported or stored, although the exhaust valve is in a closed state, the exhaust hole of the exhaust valve is always open and is set vertically upward. Therefore, outdoor dust and debris will enter the valve body through the exhaust hole. When the exhaust valve is subsequently opened, the debris accumulated inside the valve body will enter the ton barrel, which will cause pollution to the materials stored inside the ton barrel. For this reason, we propose a ton barrel auxiliary exhaust device to solve the above problem. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a ton barrel auxiliary exhaust device.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , an auxiliary exhaust device for a ton barrel, comprising an exhaust valve 1, the exhaust valve 1 is installed inside a ton barrel cover 2, the ton barrel cover 2 is a part of the ton barrel, and the ton barrel is generally connected to the ton barrel by threads, a rotating rod 3 is connected to the side of the exhaust valve 1, and a valve handle 4 is connected to the end of the rotating rod 3, the connection method between the rotating rod 3 and the exhaust valve 1 is the prior art, and its specific exhaust and closing principles are also the prior art, which will not be repeated here, a fixed block 5 is sleeved on the outside of the exhaust valve 1, and a groove hole matched with the rotating rod 3 is opened inside the fixed block 5, the top opening of the exhaust valve 1 is covered with a cover plate 10, a first gear 6 is sleeved on the outside of the rotating rod 3, and a second gear 7 is meshed on the side of the first gear 6, a moving frame 8 is distributed on the front of the fixed block 5, and teeth matched with the second gear 7 are evenly distributed on the inner side of the moving frame 8, a connecting rod 9 is symmetrically connected to the upper side of the moving frame 8, and the top of the connecting rod 9 is fixedly connected to the side of the cover plate 10.

[0023] Further, see Figure 2 and Figure 3 It can be seen that there are two groups of connecting rods 9, and the two groups of connecting rods 9 are symmetrically distributed about the central axis of the cover plate 10. The movable frame 8 is set as a U-shaped structure. The movable frame 8 is set with a U-shaped structure and is equipped with two groups of connecting rods 9. The stability of the cover plate 10 during the up and down movement can be effectively guaranteed.

[0024] Further, see Figure 3 It can be known that the bottom end of the fixed block 5 is connected to a fixed bar 11, and the upper side of the fixed bar 11 is symmetrically connected to a guide rod 12. A moving groove adapted to the guide rod 12 is provided inside the moving frame 8. When in use, the moving frame 8 can be guided by the mutual cooperation of the guide rod 12 and the moving groove.

[0025] Further, see Figure 2 It can be seen that the front of the movable frame 8 is covered with a protective plate 15, and a strip groove is opened at the center position of the protective plate 15. The opening of the strip groove can meet the normal up and down sliding of the movable frame 8. With the setting of the protective plate 15, the protection of the second gear 7 can be achieved.

[0026] Further, see Figure 4 It can be seen that a sealing ring 13 is connected to the bottom end of the cover plate 10, and an annular groove matched with the sealing ring 13 is opened at the top end of the exhaust valve 1. Through the mutual cooperation of the sealing ring 13 and the annular groove, the tightness of the cover plate 10 during the sealing process can be effectively guaranteed.

[0027] Further, see Figure 4 It can be known that the top inner wall of the exhaust valve 1 is connected to a filter plate 14, and the upper side height of the filter plate 14 and the opening height of the exhaust valve 1 are at the same horizontal plane. Since the height of the filter plate 14 is the same as the height of the exhaust valve 1, the normal coverage of the cover plate 10 can be met. Through the setting of the filter plate 14, debris can be blocked during the exhaust process.

[0028] Further, see Figure 3 It can be known that the upper side of the cover plate 10 is set to an arc-shaped structure, and the cross-sectional area of ​​the cover plate 10 is larger than the cross-sectional area of ​​the opening. The cover plate 10 with a larger cross-sectional area can improve the sealing effect of the exhaust valve 1. Since the top end of the cover plate 10 is set to an arc shape, it can prevent debris from accumulating above the cover plate 10.

[0029] Working principle: When the utility model is in use, the staff can first install the exhaust valve 1 on the ton barrel, and the cover plate 10 set on the top of the exhaust valve 1 can be used to protect the opening of the exhaust valve 1. When the ton barrel needs to be exhausted, the staff can rotate the valve handle 4 to be level with the exhaust valve 1, so that the rotating rod 3 can rotate at the same time, and when the rotating rod 3 rotates, it can drive the first gear 6 to rotate at the same time. At this time, the second gear 7 meshing with the first gear 6 can rotate in the opposite direction, and push the moving frame 8 to move upward as a whole. In the process of moving the frame 8 upward, the cover plate 10 can be driven to move upward through the setting of the connecting rod 9, and a certain gap will be maintained with the opening of the exhaust valve 1 to ensure the normal discharge of the gas inside the ton barrel. After the discharge is completed, the staff can rotate the valve handle 4 again to be perpendicular to the exhaust valve 1. At this time, the cover plate 10 can be used to block the exhaust valve 1 again through the cooperation of the first gear 6 and the second gear 7. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
