Description

Technical Field

[0001] The utility model relates to the technical field of material screening, in particular to a circular vibrating screen with high stability. Background Art

[0002] The circular vibrating screen is a high-precision fine powder screening equipment. Its working principle is to use an upright motor as the power source, and install eccentric weights at the upper and lower ends of the motor, so that the motor's rotational motion is converted into horizontal, vertical, and inclined three-dimensional motion, and then the motion is transmitted to the screen, and the material is graded and screened by vibrating the screen. In addition, because the circular vibrating screen has the characteristics of low noise, high efficiency, and easy screen change, it is widely used in the screening of powder, granules, mucus and other materials.

[0003] The screen is one of the important components of the circular vibrating screen, which plays the role of filtering and screening materials. During the use of the circular vibrating screen, it is often necessary to replace the screen model according to the screening requirements of the material. Therefore, the screen fixing structure of the vibrating screen needs to be set to a repeatedly disassembled structure.

[0004] In addition, in the existing circular vibrating screen structure, the material falls directly on the center of the top screen during the screening process. Since some granular materials are heavy, they fall directly on the center of the screen under the action of gravity. Over time, it is easy to cause the top screen to become concave and deformed, which is not convenient for subsequent material discharge and may easily cause the screen to break, affecting its use.

[0029] As described in the background technology, during the screening process of the existing circular vibrating screen, the center of the top screen bears the greatest impact force from the material, which can easily cause the screen to deform inward or even break over time, affecting its use. In addition, the existing circular vibrating screen is not easy to replace the screen.

[0030] For the reasons stated above, please refer to the attached Figure 3 , the utility model provides a circular vibrating screen with high stability, comprising a main body 1, which is mounted on a supporting frame 3 through an elastic member 2;

[0031] A vibration generating device 4, fixed to the outer end of the main body 1, for driving the main body 1 to vibrate;

[0032] A first discharge port 5 is provided on the top side of the main body 1;

[0033] The screen 7 is movably installed in the main body 1 through a supporting mechanism and is kept at a height between the highest end and the lowest end of the first discharge port 5 after installation.

[0035] Furthermore, the main body can be configured as a multi-layer structure, with a screen provided on each layer and a discharge port opened on the side wall. Since the screen on the top layer bears the greatest impact force when the material falls, and the impact force of the screen on the lower layer is reduced due to the impact buffering of the material on the upper layer, it is only necessary to install a supporting mechanism on the top layer of the screen, which also facilitates the installation of the screen.

[0036] Specifically, a slag discharge pipe 6 is provided at the outer end of the main body 1 at the position of the first discharge port 5 , and a second discharge port 5 is provided at the bottom of the main body 1 .

[0037] According to the technical features described in the previous paragraph, the shape of the support plate is set so as to provide a supporting force to the center of the screen after the screen is placed to prevent inward deformation.

[0038] Specifically, the support structure is a support plate 11 fixed to the inner wall of the main body 1, the outer end of the support plate 11 is a ring body, and the middle is a cross shape. The screen 7 is placed on the support plate 11 and is detachably fixedly connected thereto.

[0039] According to the technical features described in the previous paragraph, the shapes of the support disc and the screen are arranged to facilitate quick installation of the screen on the support disc, while greatly reducing the difficulty of installation.

[0040] Specifically, a plurality of insertion holes 13 are opened on the ring body of the support plate body 11, a plurality of insertion rods 10 matching the insertion holes 13 are arranged at the bottom of the screen 7, a connecting rod 12 is arranged at the center of the cross of the support plate body 11, and the screen 7 passes through the connecting rod 12 to contact the support plate body 11 and is pressed by the clamping block 8.

[0041] According to the technical features described in the previous paragraph, the shapes of the support disc and the screen are arranged to facilitate quick installation of the screen on the support disc, while greatly reducing the difficulty of installation.

[0042] Specifically, the connecting rod 12 is provided with an external thread, and one end of the pressing block 8 is a plane and a threaded hole matching the external thread of the outer end of the connecting rod 12 is opened at the plane end.

[0043] According to the technical features described in the previous paragraph, the external threads on the connecting rod and the threaded holes on the clamping block are provided to facilitate firmly pressing the screen against the supporting structure to prevent the screen from moving up and down due to vibration.

[0044] Specifically, the threaded hole of the pressing block 8 is a blind hole, and the depth of the threaded hole is greater than the length of the connecting rod 12 .

[0045] According to the technical features described in the previous paragraph, the depth of the threaded hole is set to ensure that the clamping block can press the screen against the supporting structure without creating any gaps, and also to prevent materials from falling into the gaps on the threaded surface and affecting subsequent thread engagement.

[0046] When installing the vibrating screen, the support plate 10 is fixed to the inner wall of the main body 1 by welding or other fixed connection methods in advance and the height is kept to adapt to the first discharge port 5. Then the screen 7 is placed on the support plate 10 and the position is adjusted until the insertion rod 9 and the insertion hole 12 match each other. The installation is completed by screwing the clamping block 8 on the connecting rod 11. The use process is consistent with the principle of the existing circular vibrating screen, which will not be repeated here.

[0047] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
