Description

Technical Field

[0001] The utility model relates to the technical field of dumping high-density granular materials, in particular to a flow-limiting barrel cover for a high-density granular material barrel. Background Art

[0002] High-density granular material barrels are barrel-shaped containers used to hold high-density granular materials. These materials, such as metal particles, certain mineral particles, and corundum, have a density significantly greater than that of air and are widely used in industry. Conventional high-density granular material barrels consist of a stainless steel barrel body and a lid. When storing high-density granular materials, the lid is snapped onto the barrel top to prevent contamination from foreign matter. The lid is only removed when transporting these materials. When pouring these barrels into other containers, the outflow rate cannot be precisely controlled, making it difficult to pour directly to the desired weight. Manual scooping is often required for final adjustment. Especially when the other container is small-diameter, the pouring process requires a funnel to prevent spillage and material waste. The existing technology urgently needs a technical means to limit the outflow rate of the high-density granular material barrel. Utility Model Content

[0026] Compared with the prior art, the present invention utilizes a barrel hoop to install a meniscus 1 on the top of a high-density granular material barrel 0; the meniscus 1 blocks most of the high-density granular material 02, and the flow limiting port 11 allows the high-density granular material 02 to flow out; the size of the flow limiting port 11 limits the upper limit of the outflow flow of the high-density granular material barrel 0 and the high-density granular material 02 poured out of the flow limiting barrel of the high-density granular material barrel 0 to a smaller range, which is conducive to pouring into small-diameter containers.

[0027] The flow restriction port 11 passes through the arc edge of the meniscus 1 to ensure that the high-density granular material barrel 0 flow restriction barrel can dump out the high-density granular material 02 cleanly.

[0028] The meniscus 1 is a semicircular plate; the entire circular plate can be cut into two congruent semicircular plates, both of which can be used as the meniscus 1, which is beneficial to reducing material loss and facilitating production management.

[0029] The flow restriction opening 11 includes an arc segment 111 at the inner end and a straight segment 112 at the side; the straight segments 112 are symmetrically arranged on both sides of the arc segment 111 and are in an outwardly open state; the shape of the flow restriction opening 11 is conducive to the discharge of high-density particulate material 02.

[0030] The barrel mouth of the high-density granular material barrel 0 is provided with an outward flange 01; the high-density granular material barrel flow-limiting barrel cover can use the flange 01 to connect the high-density granular material barrel flow-limiting barrel cover with the high-density granular material barrel 0; the top of the inner wall of the fixed ring 21 is provided with an inner convex ring 211; the distance between the inner convex ring 211 and the top of the fixed ring 21 is equivalent to the thickness of the flange 01; the inner convex ring 211 cooperates with the meniscus 1 to clamp the flange 01, thereby assisting in realizing the connection relationship between the high-density granular material barrel 0 and the high-density granular material barrel flow-limiting barrel cover.

[0031] The inner convex ring 211 matches the arc edge of the meniscus 1, and the matching length of the inner convex ring 211 and the meniscus 1 is increased as much as possible to ensure the stability of the barrel 0 for clamping the high-density granular material.

[0032] The radial cross-section of the flange 01 is circle A; the radial cross-section of the inner convex ring 211 is circle B; as long as the barrel hoop can be tightened, even if there is a certain manufacturing deviation in the inner convex ring 211, circle A and circle B can still fit tightly, and the flow-limiting barrel cover for high-density granular material barrels can also be used, which can reduce the manufacturing requirements of the flow-limiting barrel cover for high-density granular material barrels.

[0033] The barrel hoop also includes a hinge; the fixed ring 21 and the rotating ring 22 are rotated with each other through the hinge; the hinge includes a connecting plate A 241, a connecting plate B 242, and a vertical hinge shaft 243; the outer wall of the connecting plate A 241 is fixedly connected to the inner wall of the fixed ring 21; the inner wall of the connecting plate B 242 is fixedly connected to the outer wall of the rotating ring 22; the end of the connecting plate A 241 and the end of the connecting plate B 242 are hinged to each other through the vertical hinge shaft 243; in this way, when the fixed ring 21 and the rotating ring 22 are assembled into a full circle, the inner wall of the rotating ring 22 is in close contact with the outer wall of the high-density granular material barrel 0, ensuring that the barrel hoop tightly clamps the high-density granular material barrel 0.

[0034] The lock includes a lock body and a lock part 232; the lock body includes a fixed part, a rotating part 2312, and a buckle 2313; the fixed part includes a fixed plate 23111 and an ear plate 23112; the fixed plate 23111 is fixedly connected to the outer wall of the rotating ring 22; the ear plate 23112 extends outward from the end of the fixed plate 23111; one end of the rotating part 2312 is hinged to the fixed part; one end of the buckle 2313 is hinged to the middle part of the rotating part 2312, and the other end cooperates with the lock part 232; the unlocking or locking operation is realized by the rotating part 2312.

[0035] the lock 232 is mounted on the outer wall of the inclined plate 212 to increase the contact area between the rotating ring 22 and the high-density granular material barrel 0 and improve the tightness of the barrel hoop on the high-density granular material barrel 0.

[0036] There are two ear plates 23112, which are symmetrically arranged on both sides of the fixed plate 23111, so that the rotating member 2312 can rotate stably.

[0037] The working principle of this embodiment: during installation, first assemble the fixed ring 21 and the rotating ring 22 into a complete annular body that hugs the high-density granular material barrel 0, and then use the lock buckle to lock the annular body, which can hug the flow-limiting barrel of the high-density granular material barrel 0, so that the meniscus 1 is fixed on the top of the flow-limiting barrel of the high-density granular material barrel 0; the meniscus 1 blocks most of the high-density granular materials 02, and the flow-limiting port 11 allows the outflow of the high-density granular materials 02; the size of the flow-limiting port 11 limits the upper limit of the outflow flow of the flow-limiting barrel of the high-density granular material barrel 0, and also limits the high-density granular materials 02 poured out of the flow-limiting barrel of the high-density granular material barrel 0 to a smaller range, which is conducive to pouring into small-diameter containers; the inner convex ring 211 cooperates with the meniscus 1 to clamp the flange 01, thereby assisting in realizing the connection between the high-density granular material barrel 0 and the flow-limiting barrel cover of the high-density granular material barrel.

[0038] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the similarities are not repeated here. The differences are as follows: the fixing member also includes an overhanging plate 23113; the overhanging plate 23113 protrudes outward from the other end of the fixing plate 23111; a through groove 23121 is provided in the middle of the rotating member 2312 to cooperate with the overhanging plate 23113; when the lock is closed, the overhanging plate 23113 passes through the through groove 23121, which is conducive to maintaining the tube-closed state of the lock.

[0039] A lock hole 231131 is provided at the outer end of the extended plate 23113, into which a pin can be inserted or a finished lock can be installed when the lock is closed to prevent the rotating part 2312 from falling out.
