A core material and fiber screening mechanism

Abstract

This utility model discloses a core material and fiber screening mechanism, including a frame, a housing mounted on the frame, and a drum mounted inside the housing. The drum is inclined and rotatably connected to the housing, and is driven to rotate by a drive mechanism. The drum includes a rotating shaft, multiple frames mounted on the rotating shaft, and a screen mounted outside the frames. Vibrating elements are mounted on the frames. When the frames rotate with the rotating shaft, the vibrating elements reciprocate radially along the rotating shaft, striking the screen and the rotating shaft. The bottom of the screen is the crushed material outlet, the high end of the drum is the feed inlet, and the low end of the drum is the fiber outlet. This utility model, by setting a slider that can slide along a support rod, reciprocates along the axis of the support rod when the drum rotates, thereby repeatedly striking the retaining ring and the screen. This not only improves the screening efficiency of core material and fiber but also prevents fiber and large particles of core material from clogging the screen holes.

Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a core material and fiber screening mechanism. Background Technology

[0002] The main way to utilize waste core materials from door products (such as fire doors) is to use these waste core materials to prepare various new building materials, such as non-fired bricks. The method of preparing non-fired bricks from waste core materials mainly involves processing the waste core materials through crushing, screening, and magnetic separation, then mixing them with natural sand and gravel, fly ash, etc., and pressing them with a brick-making machine to produce non-fired bricks.

[0003] Since the core material of door products contains not only solid particles (mainly cement) but also fibers, the following problems exist when using a traditional vibrating screen to separate the core material from the fibers: the fibers easily clog the screen holes, thus affecting the screening efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a core material and fiber screening mechanism. By setting a slider that can slide along the support rod, it reciprocates along the axis of the support rod when the drum rotates, thereby repeatedly striking the retaining ring and the screen. This not only improves the screening efficiency of core material and fiber, but also prevents fiber and large core material particles from clogging the screen holes.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A core material and fiber screening mechanism includes a frame, a housing mounted on the frame, and a roller mounted inside the housing. The roller is inclined and rotatably connected to the housing. The roller is driven to rotate by a drive mechanism.

[0007] The drum includes a rotating shaft, multiple frames mounted on the rotating shaft, and a screen mounted outside the frames. The frames are equipped with vibrating elements. When the frames rotate with the rotating shaft, the vibrating elements reciprocate radially along the rotating shaft to strike the screen and the rotating shaft.

[0008] The material outlet is located directly below the screen, the feed inlet is at the high end of the roller, and the fiber outlet is at the low end of the roller.

[0009] Furthermore, the frame includes a supporting ring and a plurality of supporting rods evenly distributed circumferentially along the axis of rotation. The first end of the supporting rod is fixed to the axis of rotation, and the other end of the supporting rod is connected to the inner ring of the supporting ring. The screen is disposed on the outer ring of the supporting ring.

[0010] Furthermore, the multiple inner rings are connected by reinforcing ribs, which are arranged parallel to the rotating shaft.

[0011] Furthermore, the vibrating element includes a sliding block, which is slidably disposed outside the support rod.

[0012] Furthermore, the sliding block includes two C-shaped sliding plates, which are arranged opposite each other and detachably connected.

[0013] Furthermore, nuts are fixedly provided on both sides of the slide plate, and the two slide plates are detachably connected by nuts and bolts.

[0014] Furthermore, a retaining ring is also provided on the rotating shaft.

[0015] Furthermore, the portion of the housing located below the drum forms a conical hopper for crushed material.

[0016] Furthermore, the bottom end of the housing corresponding to the roller is provided with an outlet, and the outlet is connected to a fiber hopper.

[0017] The beneficial effects of this utility model are:

[0018] This invention features a slider that can slide along the support rod. When the drum rotates, the slider reciprocates along the axis of the support rod, repeatedly striking the retaining ring and the screen. This not only improves the screening efficiency of the core material and fiber, but also prevents the fiber and large particles of core material from clogging the screen holes.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See Figures 1-5 This utility model provides a technical solution:

[0027] Example:

[0028] like Figures 1-5 As shown, a core material and fiber screening mechanism includes a frame 1, a housing 2 disposed on the frame 1, and a roller 3 disposed inside the housing 2. The roller 3 is inclined and rotatably connected to the housing 2. The roller 3 is driven to rotate by a drive mechanism 4.

[0029] like Figure 3 and Figure 5 As shown, the roller 3 includes a rotating shaft 5, a plurality of frames 6 arranged on the rotating shaft 5, and a screen 7 arranged outside the frames 6. The frames 6 are provided with vibrating elements. When the frames 6 rotate with the rotating shaft 5, the vibrating elements reciprocate radially along the rotating shaft 5 to strike the screen 7 and the rotating shaft 5.

[0030] like Figure 1 As shown, the screen 7 is located directly below the crushed material outlet, the high end of the roller 3 is the feed inlet, the low end of the roller 3 is the fiber outlet, and the portion of the housing 2 located below the roller 3 forms a conical crushed material hopper 16; the housing 2 is provided with an outlet at the bottom end corresponding to the roller 3, and the outlet is connected to a fiber hopper 17.

[0031] The frame 6 includes a supporting ring 8 and a plurality of supporting rods 9 evenly distributed around the circumference of the rotating shaft 5. The first end of the supporting rod 9 is fixed to the rotating shaft 5, and the other end of the supporting rod 9 is connected to the inner ring of the supporting ring 8. The screen 7 is disposed on the outer ring of the supporting ring 8.

[0032] The multiple inner rings are connected by reinforcing ribs 10, which are arranged parallel to the rotating shaft 5.

[0033] The vibrating element includes a sliding block 11, which is slidably disposed outside the support rod 9.

[0034] The sliding block 11 includes two C-shaped sliding plates 12 (the sliding plates 12 can be, but are not limited to, C-shaped steel). The two sliding plates 12 are arranged opposite each other and detachably connected. A square or circular connecting cavity is formed between the two sliding plates 12. In this embodiment, it is a square cavity. The two sliding plates 12 are sleeved on the outside of the support rod 9 through the connecting cavity.

[0035] Nuts 13 are fixedly provided on both sides of the slide plate 12, and the two slide plates 12 are detachably connected by nuts 13 and bolts 14. Taking the same side of the two slide plates 12 as an example: two coaxial nuts 13 are provided on the two slide plates 12, and the connection of the slide plates 12 on the same side can be achieved by bolting the two coaxial nuts 13. The other side is the same.

[0036] like Figure 3 and Figure 5 As shown, the rotating shaft 5 is also provided with retaining rings 15. Two retaining rings 15 are provided, sandwiching the support plate in the middle. Each retaining ring 15 has a regular polygonal structure. In this embodiment, with six support rods 9, the retaining rings 15 are regular hexagonal structures, with each side of the retaining ring 15 corresponding to a slider. When the slider impacts the rotating shaft 5 under gravity, it directly impacts the retaining ring 15, thus preventing the slider from directly impacting the rotating shaft 5 and ensuring the service life of the rotating shaft 5.

[0037] 1. The two ends of the rotating shaft 5 are rotatably connected to the bearings respectively; 2. The drive mechanism 4 includes a motor, and the output shaft of the motor is equipped with a drive sprocket or drive pulley. The end of the rotating shaft 5 is equipped with a driven sprocket or driven pulley. The drive sprocket or drive pulley is connected to the driven sprocket or driven pulley through a chain or belt, so that the motor drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, the frame 6 and the screen 7 on it rotate synchronously.

[0038] Working principle: In use, after the core material is crushed, it is fed into the high end (feed inlet) of the drum 3 by a hoist in this embodiment. After the core material enters the drum 3, the drum 3 rotates, the sliding block 11 moves axially along the support rod 9, the upper slider moves from top to bottom under the action of gravity to strike the retaining ring 15, and the lower slider moves from top to bottom to strike the lower screen 7.

[0039] Under the combined effects of centrifugal force, gravity, and vibration generated by the slider during rotation, fine particles fall from the screen 7 to the crushing hopper 16 below, while fibers and large particles move towards the lower end along the inclined roller 3 due to the compression of the material and the action of gravity, and finally enter the fiber hopper 17.

[0040] This invention features a slider that can slide along the support rod. When the drum rotates, the slider reciprocates along the axis of the support rod, repeatedly striking the retaining ring and the screen. This not only improves the screening efficiency of the core material and fiber, but also prevents the fiber and large particles of core material from clogging the screen holes.

[0041] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
