Technical Field

[0001] This utility model relates to a powder feeding tank feeding structure. Background Technology

[0002] In the field of powder feeding equipment, the sealing structure of the feed tank directly affects production efficiency and environmental safety. Traditional powder feed tanks generally use flange covers or bolt-fastened sealing devices for the feed inlet. Each feeding requires disassembling and assembling multiple sets of bolts, consuming a lot of manpower and time. This significantly reduces operating efficiency, especially in frequent feeding scenarios. Moreover, the bolts are prone to stripping and corrosion due to repeated operation, increasing maintenance costs and the risk of seal failure. In view of this, this utility model proposes a powder feed tank feeding structure to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a powder feeding tank structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A powder feeding tank structure includes a tank body, on which a feeding pipe is provided; A placement ring is provided inside the feed pipe, and the placement ring is fixedly connected to the feed pipe. A sealing circular plate is provided on the placement ring, and a support rod is provided on the feed pipe. A positioning component is provided on the support rod, and the sealing circular plate is mounted on the positioning component. The sealing circular plate rotates about the axis of the support rod, so that the sealing circular plate is aligned with the axis of the placement ring. The positioning component drives the sealing circular plate to descend and contact the placement ring to complete the sealing process.

[0005] As an improvement to the above technical solution, a support ring is fixedly provided on the outside of the feed pipe; The support ring has a support hole, and the outer wall of the support rod is rotatably fitted with a support sleeve, which is fixedly installed in the support hole.

[0006] As an improvement to the above technical solution, a first support ring plate is fixedly provided on the outer wall of the support rod, and a second support ring plate is fixedly provided on the support sleeve; A torsion spring is provided between the first support ring plate and the second support ring plate, and the torsion spring is sleeved on the outer wall of the support rod.

[0008] As an improvement to the above technical solution, the positioning component includes a positioning screw, which passes through the connecting block and is connected to the sealing circular plate; The outer wall of the positioning screw is threaded with a positioning nut, and a rotating ring is provided on the positioning nut. Multiple sets of rotating rods are provided between the positioning nut and the rotating ring, and the rotating ring is rotatably mounted on the connecting block.

[0009] As an improvement to the above technical solution, the outer wall of the positioning nut is provided with multiple sets of actuating rods, and an actuating ring is provided between the multiple sets of actuating rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By using a placement ring set inside the feed pipe and a rotatable sealing disc in synergy, the operator can quickly move the sealing disc out to open the feeding channel. After feeding is completed, the sealing disc only needs to be manually rotated to a position coaxial with the placement ring, and then driven by the positioning component to press down and contact the placement ring. This design significantly simplifies the sealing operation process, reduces manual labor intensity, and ensures the high efficiency and airtightness of the feed pipe, avoiding material leakage or environmental pollution. Compared to traditional flange covers or bolt-fastening sealing methods, this structure eliminates the tedious steps of repeatedly disassembling and assembling bolts. Sealing can be completed in just two steps: rotation and pressing down, which greatly shortens the feeding cycle and is suitable for industrial scenarios that require frequent feeding. Its compact mechanical linkage design reduces the space occupied by external components and meets the requirements of equipment integration. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: like Figure 1-10 As shown, this embodiment proposes a powder feeding tank structure, including a tank body 10, on which a feeding pipe 30 is provided; A placement ring 33 is provided inside the feed pipe 30. The placement ring 33 is fixedly connected to the feed pipe 30. A sealing circular plate 20 is provided on the placement ring 33. A support rod 40 is provided on the feed pipe 30. A positioning component 60 is provided on the support rod 40. The sealing circular plate 20 is mounted on the positioning component 60. The sealing circular plate 20 rotates about the axis of the support rod 40, so that the sealing circular plate 20 is aligned with the axis of the placement ring 33. The positioning component 60 drives the sealing circular plate 20 to descend and contact the placement ring 33 to complete the sealing process.

[0017] In this embodiment, when feeding materials, the sealing disc 20 is first removed from the placement ring 33, and then the material is introduced into the inner cavity of the tank 10 through the feed pipe 30. After the material is fed, the sealing disc 20 is manually rotated around the axis of the support rod 40 until the sealing disc 20 is aligned with the axis of the placement ring 33. Then, the sealing disc 20 is driven to move towards the placement ring 33 through the positioning component 60 until the sealing disc 20 contacts the placement ring 33 in the feed pipe 30, thus completing the sealing process. By having the placement ring 33 set inside the feed pipe 30 work in conjunction with the rotatable sealing disc 20, the operator can quickly move the sealing disc 20 out to open the feeding channel. After feeding is completed, the sealing disc 20 only needs to be manually rotated to a position coaxial with the placement ring 33, and then driven by the positioning component 60 to press down and contact the placement ring 33. This design significantly simplifies the sealing operation process, reduces the intensity of manual labor, and at the same time ensures the high efficiency of the airtightness of the feed pipe 30, avoiding material leakage or environmental pollution. Compared to traditional flange covers or bolt-fastening sealing methods, this structure eliminates the tedious steps of repeatedly disassembling and assembling bolts. Sealing can be completed in just two steps: rotation and pressing down, which greatly shortens the feeding cycle and is suitable for industrial scenarios that require frequent feeding. Its compact mechanical linkage design reduces the space occupied by external components and meets the requirements of equipment integration.

[0018] Specifically, a support ring 32 is fixedly provided on the outside of the feed pipe 30; The support ring 32 has a support hole 31, and the outer wall of the support rod 40 is rotatably fitted with a support sleeve 44, which is fixedly installed in the support hole 31.

[0019] In this embodiment, the support ring 32 is fixedly disposed outside the feed pipe 30, and a high-strength mounting base is formed through the support hole 31 opened therein; the support sleeve 44 is rigidly fixed inside the support hole 31, so that the support rod 40 obtains radial full constraint positioning through the support sleeve 44, effectively suppressing vibration or displacement during operation, ensuring that the rotation axis of the support rod 40 always remains stable, and laying a structural foundation for the precise rotational movement of the sealing disc 20.

[0020] Specifically, a first support ring plate 41 is fixedly provided on the outer wall of the support rod 40, and a second support ring plate 43 is fixedly provided on the support sleeve 44; A torsion spring 42 is provided between the first support ring plate 41 and the second support ring plate 43, and the torsion spring 42 is sleeved on the outer wall of the support rod 40.

[0021] In this embodiment, the torsion spring 42 is sleeved on the outer wall of the support rod 40, and its two ends are rigidly connected to the first support ring plate 41 and the second support ring plate 43 respectively, forming a pre-tightening torque storage structure. When the sealing disc 20 is manually rotated to open the feed port, the torsion spring 42 accumulates elastic potential energy as the support rod 40 rotates. After the operation is completed, the sealing disc 20 is released, and the torsion spring 42 drives the support rod 40 to automatically rotate in the opposite direction through the release of elastic potential energy, thereby driving the sealing disc 20 to accurately reset to the initial closed preparation position, completely avoiding manual secondary adjustment and greatly improving the operation efficiency.

[0022] Specifically, a connecting rod 50 is provided on the support rod 40, and a connecting block 65 is provided on the connecting rod 50; The positioning component 60 is disposed on the connecting block 65.

[0023] Specifically, the positioning component 60 includes a positioning screw 61, which passes through the connecting block 65 and is connected to the sealing circular plate 20; The outer wall of the positioning screw 61 is threaded with a positioning nut 64, and a rotating ring 68 is provided on the positioning nut 64. Multiple sets of rotating rods 67 are provided between the positioning nut 64 and the rotating ring 68. The rotating ring 68 is rotatably mounted on the connecting block 65.

[0024] Specifically, the outer wall of the positioning nut 64 is provided with multiple sets of actuating rods 62, and actuating rings 63 are provided between the multiple sets of actuating rods 62.

[0025] In this embodiment, when the sealing disc 20 is pressed down, the actuating ring 63 is manually rotated, which in turn drives the positioning nut 64 to rotate via the actuating rod 62. Since the positioning nut 64 and the positioning screw 61 are threaded together, the positioning screw 61 descends, thereby causing the sealing disc 20 on the positioning screw 61 to descend so as to perform the sealing process.

[0026] Specifically, two sets of positioning frames 66 are symmetrically arranged on the sealing circular plate 20, and the positioning screw 61 is arranged between the two sets of positioning frames 66; The positioning screw 61 is connected to the two sets of positioning frames 66 by bolts.

[0027] In this embodiment, the positioning screw 61 is connected to the two sets of positioning frames 66 by bolts, which facilitates the disassembly and maintenance of the sealing disc 20.

[0028] Specifically, a sealing ring groove 22 is provided on the sealing circular plate 20, and a sealing gasket 23 is provided in the sealing ring groove 22; The sealing circular plate 20 is also provided with a movable rod 21, which is coaxial with the sealing circular plate 20.

[0029] In this embodiment, the sealing gasket 23 can effectively improve the overall sealing performance, and the movable rod 21 can facilitate the pulling of the sealing disc 20 to rotate around the axis of the support rod 40.

[0030] 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.
