Description

Technical Field

[0001] The utility model relates to the technical field of rotary vibrating screen equipment, and more particularly to a dust-proof rotary vibrating screen suitable for powder production. Background Art

[0002] A vibrating screen, also known as a vibration screen, can screen and sort materials. The screen is equipped with a mesh that vibrates to filter the material on the mesh. Smaller-diameter materials fall below the mesh and are discharged from the outlet below the screen, while larger-diameter materials remain on the mesh, achieving screening and sorting. A vibrating screen is typically equipped with multiple outlets for discharging the screened material through different pipes.

[0003] The top of the rotary vibrating screen is usually open to facilitate the addition of materials at any time. At the same time, the open top facilitates the dumping of materials and reduces the spillage of materials to the outside. However, when screening dusty materials such as powders, the open setting will cause the dusty materials to scatter due to vibration, which not only causes the loss of materials, but also affects the surrounding environment. Therefore, a dust cover is set on the top of the rotary vibrating screen to prevent the dusty materials from escaping. For example, the Chinese patent with application number 202120479079.6 discloses a dust-proof vibrating screen cover, the structure of which includes: a cover; a feed port, the feed port is fixed to the top of the cover, one side of the inner wall of the feed port is fixedly connected to a first inclined plate, and the other side of the feed port is fixedly connected to a second inclined plate, the inner wall of the feed port is fixedly connected to two discs, and a rotating shaft is rotatably connected between the two discs. The dustproof vibrating screen cover has a structure on the top dust cover to prevent materials from escaping from the entrance, which has the effect of preventing powder materials from escaping, but there are still the following problems:

[0004] 1. Due to the poor fluidity of powder materials, when screening a large amount of dust materials, the accumulated dust materials will reduce the screening efficiency. At the same time, when the materials hit the screen surface, a large airflow will be generated, which will easily cause a large amount of dust to fly. Although the screening quality can be improved and the dust can be reduced by adding materials multiple times, multiple additions will consume a lot of labor and prolong the screening time.

[0005] 2. The feeding port on the top of the dust cover is small, and leakage may occur when adding powder, resulting in unnecessary waste of materials. If the feeding port is too large, dust will escape.

[0006] Therefore, it is necessary to propose a dust-proof rotary vibrating screen suitable for powder production to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4, a dust-proof rotary vibrating screen suitable for powder production, including a rotary vibrating screen 101 and multiple support frames 102 located on the rotary vibrating screen 101, the top of the rotary vibrating screen 101 is connected to multiple support frames 102 in sequence through clamps, the interior of the support frame 102 is used to connect the screen, and a cone disk 103 is installed in the top support frame 102, the support frame 102 and the rotary vibrating screen 101 are connected by a clamp, the interior of the bottom support frame 102 is connected with the screen, when the powder material flows out from between the upper guide edge 111 and the lower guide edge 110, it will fall on the bottom screen, the interior of the top support frame 102 is connected with the cone disk 103, the center position of the cone disk 103 is connected to the discharge sleeve 104, the discharge sleeve 104 A circular array of drop holes is provided on the outer wall. The powder material on the conical disk 103 can enter between the upper guide edge 111 and the lower guide edge 110 through the drop holes on the discharge sleeve 104, and then be guided to diverge to the surrounding areas by the lower guide edge 110 and the upper guide edge 111, so that it can fall on the bottom screen over a large area, thereby improving the screening efficiency. A top cover 105 is provided on the top of the support frame 102. The top cover 105 can be opened by a hinge. One end of the top cover 105 and the top support frame 102 are connected by a hinge, and the other end of the top cover 105 and the top support frame 102 are connected by a buckle. The buckle makes it easy to fix the top cover 105 on the support frame 102, thereby improving the stability during vibration.

[0028] The following provides a structure for blocking the movement of materials from the cone 103 to the screen: Figure 3 The inside of the discharge sleeve 104 is connected to a moving rod 106 which slides up and down. A cavity 107 is opened inside the top of the discharge sleeve 104. The top opening of the discharge sleeve 104 is set, but the opening is smaller than the diameter of the cavity 107. The top of the moving rod 106 is connected to a moving plate 108 located in the cavity 107. A spring 109 is connected between the bottom of the moving plate 108 and the cavity 107. The spring 109 pushes the moving rod 106 to the top through the moving plate 108, so that the lower guide edge 110 of the bottom will fit into the bottom of the upper guide edge 111, blocking the channel for the powder material to move toward the screen.

[0029] Specifically, refer to Figure 3The bottom of the moving rod 106 is connected to a conical lower guide edge 110, and the bottom of the discharge sleeve 104 is connected to an upper guide edge 111 corresponding to the lower guide edge 110. The lower guide edge 110 and the upper guide edge 111 can fit together to block the movement of the material. The position of the moving plate 108 in the cavity 107 affects the distance between the upper guide edge 111 and the lower guide edge 110. When the top cover 105 is opened, the spring 109 pushes the moving rod 106 to the top, so that the lower guide edge 111 can be pressed against the bottom of the discharge sleeve 104. The guide edge 110 and the upper guide edge 111 are closed together, thereby blocking the movement of the material and preventing the dust stirred up at the bottom of the cone 103 from escaping. It should be noted that when the top cover 105 is opened to add material, if the rotary vibrating screen 101 is not stopped and there is material on the cone 103, a small amount of dust will be stirred up at the top of the cone 103, but it will not affect the use. When the material on the top of the cone 103 has entered the bottom, the top cover 105 can be opened at this time and no dust will be stirred up.

[0030] The following provides a structure in which the lower guide edge 110 and the upper guide edge 111 can automatically open after the top cover 105 is closed, thereby allowing the material to flow: Figure 3 and Figure 4 Specifically, the middle part of the top cover 105 is threadedly connected to a threaded rod 112, and the internal spline of the threaded rod 112 is connected to a lifting block 113. The lifting block 113 moves up and down inside the threaded rod 112 through the spline. A limiting device is provided inside the threaded rod 112 to prevent the lifting block 113 from completely moving out of the threaded rod 112. The top of the top cover 105 is connected to a storage platform 114, which is used to clamp the rotating block 115. When the rotating block 115 rotates due to vibration, the top of the lifting block 113 is connected to a rotating block 115 that can enter the storage platform 114.

[0031] Specifically, refer to Figure 3 and Figure 4 The top of the discharge sleeve 104 is provided with an opening smaller than the diameter of the cavity 107. The plug 116 can penetrate into the cavity 107 through the opening and push the movable plate 108 downward. The depth of the plug 116 is adjusted by rotating the rotating block 115, thereby adjusting the downward pressure depth of the movable plate 108. The distance between the upper guide edge 111 and the lower guide edge 110 can be controlled, thereby controlling the amount of powder material added. The bottom of the threaded rod 112 is connected to the plug 116 that can extend into the cavity 107.

[0032] Specifically, refer to Figure 4The bottom of the rotating block 115 is connected to a spring 109, and the spring 109 pulls the rotating block 115 to be located in the storage platform 114. The bottom of the spring 109 is connected to a rotating ring 117. The rotating block 115 drives the rotating ring 117 to rotate through the spring 109 to avoid frictional contact between the spring 109 and the top cover 105. The bottom of the rotating ring 117 is rotatably connected to the top cover 105.

[0033] Specifically, refer to Figure 1 and Figure 2 An observation plate 118 and a feed cover 119 are installed on the top cover 105. The observation plate 118 is made of PVC. The transparent observation plate 118 makes it easy for the user to observe the internal material and add material. The feed cover 119 makes it easy to connect the rotary vibrating screen 101 with other feeding devices to achieve the effect of automatic feeding.

[0034] In this embodiment, the top cover 105 is opened by snapping, and the powder material is poured onto the conical disk 103, which is then snapped closed. When the top cover 105 is closed, the top head 116 at the bottom is inserted into the cavity 107 and presses the movable plate 108 downward, causing the lower guide edge 110 to move downward, thereby increasing the distance between the upper guide edge 111 and the lower guide edge 110. At this time, the material at the top of the conical disk 103 can flow through the space between the lower guide edge 110 and the upper guide edge 111 to the bottom screen, and then the powder is screened.

[0035] When the flow rate of the powder moving toward the screen needs to be adjusted, the rotating block 115 is pulled upward and rotated. The rotating block 115 drives the threaded rod 112 to rotate through the lifting block 113, and the threaded rod 112 drives the bottom head 116 to move, thereby adjusting the depth of the head 116 entering the cavity 107.

[0036] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
