Technical Field

[0001] The utility model belongs to the technical field of limestone powder storage bins, in particular to a limestone powder production and storage bin. Background Art

[0002] Limestone powder production storage silo is one of the key equipment for producing and storing limestone powder. The material of the production storage silo is usually carbon steel or other corrosion-resistant materials to ensure the durability and service life of the equipment. The production storage silo usually includes a feed port, a storage area, a discharge port and other parts. The feed port is used to input limestone powder materials into the storage silo, the storage area is used to store limestone powder, and the discharge port is used to output the stored limestone powder;

[0003] After limestone powder is produced and stored, it needs to be transported to the required place by a professional limestone powder transfer vehicle. When loading the transfer vehicle, the discharge port at the bottom of the storage bin needs to be connected with the feed port at the top, and then the valve is opened to transport the limestone powder inside the storage bin to the transfer vehicle;

[0004] However, in actual use, since the unloading position of the storage bin is fixed, and the feed port of the transfer vehicle is fixed to the tank body, it is necessary to rely on the driver's skills and experience to match the positions of the two, and even other auxiliary personnel are required, which is time-consuming and labor-intensive, inefficient, and poorly adaptable;

[0005] In order to solve the above problems, the present application proposes a limestone powder production and storage silo. Utility Model Content

[0029] See also Figure 1-5 As shown, the utility model is a limestone powder production and storage silo, comprising a storage silo body 1 and a discharge valve 2 fixed at a discharge port at the bottom of the storage silo body 1, a first angle conduit 3 is rotatably provided at the bottom of the discharge valve 2, a second angle conduit 4 is provided at the lower end of the first angle conduit 3, a discharge conduit 5 is provided at the lower end of the second angle conduit 4, a telescopic component 6 is provided between the first angle conduit 3 and the second angle conduit 4 and between the second angle conduit 4 and the discharge conduit 5, two groups of telescopic components 6 can drive the discharge conduit 5 to adjust in the horizontal and vertical directions, the rotation of the first angle conduit 3 and the discharge valve 2 can drive the discharge conduit 5 to rotate within a circumferential range, and a docking component 7 is provided at the lower end of the outer side of the discharge conduit 5 for clamping the discharge conduit 5 with the external feed port.

[0030] Among them, the connection between the first angle duct 3 and the second angle duct 4 is inclined, the discharge valve 2 and the discharge duct 5 are distributed in parallel, the telescopic component 6 includes an inner telescopic sleeve 61 on the inside and an outer telescopic sleeve 62 on the outside, and a telescopic tube 63 sliding between the inner telescopic sleeve 61 and the outer telescopic sleeve 62. In this embodiment, the telescopic component 6 between the first angle duct 3 and the second angle duct 4 can change the horizontal position of the discharge duct 5, and the telescopic component 6 between the second angle duct 4 and the discharge duct 5 can change the vertical position of the discharge duct 5. Then, with the rotation of the first angle duct 3 and the discharge valve 2, a certain range of motion of the discharge duct 5 can be provided, which is convenient for flexible docking with the external feed port.

[0031] Among them, the telescopic component 6 also includes a limit slider 64 formed on the outside of the telescopic tube 63 and a limit slot 65 opened on the inside of the outer telescopic sleeve 62. The limit slider 64 and the limit slot 65 are multiple groups distributed in a circle, and the limit slider 64 slides in the limit slot 65. In this embodiment, the cooperation between the limit slider 64 and the limit slot 65 avoids the rotation between the first angle conduit 3, the second angle conduit 4, and the discharge conduit 5, thereby ensuring that the discharge conduit 5 is always facing directly downward, which is convenient for docking with the external feed port.

[0032] Among them, the docking component 7 includes a rotating rod 71 hinged at the outer bottom of the discharge conduit 5 through a bracket, a clamping block 72 integrally formed at the lower end of the rotating rod 71, and a guide rod 73 integrally formed at the upper end of the rotating rod 71.

In this embodiment, the docking component 7 can facilitate the rapid connection of the discharge conduit 5 with the feed port of the transfer vehicle, and at the same time, it can also limit the first angle conduit 3, the second angle conduit 4, and the discharge conduit 5 in this state, so as to facilitate the docking of the pipe mouths when the limestone powder is discharged, and facilitate the discharge work.

[0033] Among them, a limiting groove 77 for the upper rotation of the rotating rod 71 is opened on the driving sleeve 74. The cross-section of the driving sleeve 74 is "U"-shaped, and the guide rod 73 slides on the inner side of the "U" shape. The rotating rod 71 is a plurality of circumferentially distributed ones, and the clamping block 72 can clamp the feed port connected to the discharge conduit 5 and the discharge conduit 5 by rotation. In this embodiment, the limiting groove 77 can also prevent the driving sleeve 74 from rotating, thereby ensuring the effective cooperation of the threaded structure.

[0034] Among them, the internal threaded sleeve 75 is threadedly connected with the external threaded sleeve 76, and a screw wheel for easy use is also provided at the upper end of the external part of the internal threaded sleeve 75. In this embodiment, the moving force formed by the threaded cooperation drives the rotating rod 71 to rotate, thereby realizing the clamping and loosening of the clamping block 72, which has the advantages of reliable structure and convenient operation.

[0035] It can be understood that, firstly, the first angle duct 3, the second angle duct 4 and the discharge duct 5 are flexibly arranged to cover the position of the discharge duct 5 within a certain range. As long as the feed port of the transfer vehicle is located within the range, the discharge duct 5 can be quickly connected thereto, so as to facilitate the docking work of the pipe port when the limestone powder is discharged. Secondly, the docking component 7 can quickly dock the discharge duct 5 with the feed port of the transfer vehicle, so as to facilitate the discharge work, and at the same time, the first angle duct 3, the second angle duct 4 and the discharge duct 5 can be limited in this state.

[0036] A specific application of this embodiment is: adjust the feed port position at the upper end of the transfer vehicle to within the coverage range of the discharge conduit 5, hold the discharge conduit 5 and directly dock it with the feed port of the transfer vehicle, during the docking process, the telescopic component 6 between the first angle conduit 3 and the second angle conduit 4 can adjust the horizontal position of the discharge conduit 5, and the telescopic component 6 between the second angle conduit 4 and the discharge conduit 5 can adjust the vertical position, until the discharge conduit 5 is docked with the feed port of the transfer vehicle, at this time, rotate the internal threaded sleeve 75, the internal threaded sleeve 75 drives the drive sleeve 74 to slide upward on the outside of the discharge conduit 5 through the spiral with the external threaded sleeve 76, the drive sleeve 74 drives the guide rod 73 to move upward, the rotating rod 71 rotates to drive the clamping block 72 to move in the opposite direction, until the clamping block 72 clamps the bottom of the discharge conduit 5 and the feed port of the transfer vehicle, as shown in FIG. Figure 4 In the state shown, the discharge valve 2 is opened to discharge the limestone powder;

[0037] After unloading is completed, first close the discharge valve 2, then loosen the docking component 7, and the discharge conduit 5 is disconnected from the feed port. When it needs to be transported again, repeat the above steps;

[0038] The telescopic component 6 is used as follows: during the adjustment process, the telescopic tube 63 slides between the inner telescopic sleeve 61 and the outer telescopic sleeve 62, and the limit slider 64 slides in the limit slide groove 65.
