Description

Technical Field

[0001] This utility model relates to the field of rotary vibrating screen technology, specifically a novel dust cover and installation structure for rotary vibrating screens. Background Technology

[0002] A vibrating screen is a high-precision fine powder screening machine. It is widely used in industries such as chemical, abrasive and ceramic, food, papermaking, metallurgy, pharmaceutical, and environmental protection.

[0003] The quality of vibrating screens on the market varies greatly, especially the dust cover itself and the connection mechanism between it and the screen frame. Most dust covers adopt a shell structure, which has poor structural strength, especially at the connection with the screen frame. Not only is the dust cover itself prone to deformation when placed, but it also lacks vibration buffering during use, making it easily damaged. In addition, it is inconvenient to connect and install the dust cover to the screen frame, causing many inconveniences for users. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new dust cover and installation structure for a rotary vibrating screen, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model discloses a novel dust cover for a vibrating screen. The technical solution includes a dust cover body and a feed inlet. The feed inlet is provided on the dust cover body and is coaxially arranged with the dust cover body. The edge of the dust cover body is also provided with a bending groove and a downwardly inclined bending section. By providing a bending groove on the edge of the dust cover body, the contact surface between it and the screen frame is increased. Under vibration conditions, it is not easy for gap leakage to occur, and the horizontal deformation resistance of the edge is also improved.

[0006] As a preferred embodiment of this utility model, the inclination angle of the bending channel is 5°.

[0007] A novel dust cover installation structure for a vibrating screen includes a screen frame and a discharge port. The discharge port is connected to the side wall of the screen frame. The structure also includes a sealing element and a dust cover body. The sealing element is provided between the dust cover body and the screen frame. The sealing element and the dust cover body have a receiving groove and a protrusion on their facing surfaces. The receiving groove and the protrusion are respectively adapted to the bending section and the bending channel. The side wall of the sealing element has a downward flange for engaging with the screen frame. The dust cover body, the screen frame, and the sealing element are connected by a retaining ring. The downward flange on the sealing element serves a positioning function during installation and does not affect the retaining ring's clamping and limiting effect on the dust cover body and the screen frame.

[0008] As a preferred technical solution of this utility model, sealing lines are provided on both the top and bottom surfaces of the sealing element to increase the sealing performance with the dust cover and the sieve frame.

[0009] As a preferred technical solution of this utility model, the sealing element is further provided with a cavity inside, and a hollow structure is added in the middle part of the sealing ring, which facilitates a wider range of sealing elasticity and makes it easier to assemble the material distribution buffer plate in the opening gap.

[0010] As a preferred embodiment of this utility model, the edge of the retaining ring is provided with an outward flange, which increases the structural strength of the retaining ring and facilitates the assembly of the dust cover and the sieve frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting a bending groove at the edge of the dust cover, the present utility model increases the contact surface between the dust cover and the screen frame, making it less likely to cause gap leakage under vibration conditions, and also improving the horizontal deformation resistance of the edge.

[0012] In this invention, a downwardly inclined bent section is provided on the dust cover, which, together with the receiving groove and sealing line on the sealing element, enhances the connection and sealing performance between the dust cover and the screen frame. A downward-curved edge is provided on the sealing element, which serves as a positioning function during installation and does not affect the clamping and limiting of the retaining ring between the dust cover and the screen frame. A hollow structure is added to the middle part of the sealing ring to facilitate a wider sealing elastic range and to make it easier to assemble the material distribution buffer plate in the opening gap.
