Description

Technical Field

[0001] The utility model relates to the technical field of wood screening equipment, in particular to a drum type screener. Background Art

[0002] During the wood screening process, the vibrating screen uses a horizontal axis shaking method to screen materials. This method may cause large wood chips to accumulate on the screen, causing blockage on the screen surface. Due to the blockage problem, the vibrating screen needs to be cleaned at least twice every 8 hours, which not only reduces the screening efficiency, but also increases the labor intensity of the operator. At present, in order to improve the screening efficiency, the vibrating screen is often vibrated by increasing the Z-axis vibration (vertical axial vibration) of the vibrating screen to screen wood and prevent blockage, but this vibration method will increase the load on the bearing, resulting in a sharp shortening of the bearing life and frequent replacement.

The following is a description of the embodiments of the present invention based on its overall structure.

[0021] Example 1

[0022] like Figure 1 A drum-type screen is shown, comprising an upper inclined cylinder, a lower inclined cylinder, an upper roller rod, a lower roller rod, a steering hopper and a spherical hopper; the lower inclined cylinder is arranged horizontally, with the left end higher than the right end; the upper inclined cylinder is arranged longitudinally, with the rear end higher than the front end; the steering hopper is arranged at the left end of the lower inclined cylinder; a spherical hopper is arranged above the steering hopper; the front end of the upper inclined cylinder is arranged above the spherical hopper; an upper roller rod is arranged on the periphery of the upper inclined cylinder; and a lower roller rod is arranged on the periphery of the lower inclined cylinder.

[0023] Next, the working principle of the embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0024] The upper inclined cylinder and the lower inclined cylinder are used to screen wood. The diameter of the sieve holes on the upper inclined cylinder is 5mm, and the diameter of the sieve holes on the lower inclined cylinder is 55mm. The wood enters from the higher end of the upper inclined cylinder. After being screened by the upper inclined cylinder, the wood enters the spherical hopper, and then enters the steering hopper from the spherical hopper, and then enters the lower inclined cylinder from the steering hopper to perform secondary screening on the wood. The upper roller rod is used to rotate the upper inclined cylinder, and the lower roller rod is used to rotate the lower inclined cylinder. By rotating the upper inclined cylinder and the lower inclined cylinder, blockage can be prevented in the upper inclined cylinder and the lower inclined cylinder to ensure that the screener can work continuously. The steering hopper is tilted, and the upper end opening is connected to the lower end outlet of the spherical hopper, and the lower end opening is connected to the higher end of the lower inclined cylinder. One end of the upper roller rod or the lower roller rod rests on the outer side of the cylinder body of the upper inclined cylinder or the lower inclined cylinder, and the other end extends outward and is connected to the motor.

[0025] Example 2

[0026] The difference between this embodiment and embodiment 1 is that the spherical hopper is hemispherical, with an opening at the lower end. The spherical hopper is hemispherical, with the upper end located below the lower end of the upper inclined cylinder and the lower end located above the steering hopper.

[0027] The working principle of this embodiment is the same as that of Embodiment 1.

[0028] Example 3

[0029] The difference between this embodiment and Embodiment 2 is that when the upper roller rods are arranged on the outer periphery of the upper inclined cylinder, two upper roller rods are arranged on the upper half of the outer periphery of the upper inclined cylinder, and two upper roller rods are arranged on the lower half of the outer periphery of the upper inclined cylinder; when the lower roller rods are arranged on the outer periphery of the lower inclined cylinder, two lower roller rods are arranged on the lower half of the outer periphery of the lower inclined cylinder.

[0030] The two upper rollers arranged at the lower half of the upper inclined cylinder play a supporting role, and the two upper rollers arranged at the upper half of the upper inclined cylinder play a limiting role. By arranging four upper rollers on the outer circumference of the upper inclined cylinder, the upper inclined cylinder can work smoothly. The two lower rollers arranged at the lower half of the lower inclined cylinder play a supporting role, and the two lower rollers arranged at the upper half of the lower inclined cylinder play a limiting role. By arranging four upper rollers on the outer circumference of the lower inclined cylinder, the lower inclined cylinder can work smoothly.

[0031] The working principle of this embodiment is the same as that of Embodiment 1.

[0032] Example 4

[0033] This embodiment differs from Embodiment 3 in that it further comprises a second material collection box and a first material collection box; the second material collection box is arranged below the lower inclined cylinder; and the first material collection box is arranged below the upper inclined cylinder.

[0034] The second material collecting box and the first material collecting box are respectively used to receive the wood screened from the upper inclined cylinder or the lower inclined cylinder.

[0035] The working principle of this embodiment is the same as that of Embodiment 1.

[0036] Example 5

[0037] This embodiment differs from Embodiment 4 in that it further includes a scraper connecting rod, a scraper and a support frame; one end of the scraper is arranged on the edge of the inner wall of the lower inclined cylinder or the upper inclined cylinder; the other end of the scraper extends out of the lower inclined cylinder or the upper inclined cylinder; the support frame is arranged above the upper inclined cylinder and the lower inclined cylinder; one end of the scraper connecting rod is connected to one end of the scraper extending out of the lower inclined cylinder or the upper inclined cylinder, and the other end is connected to the support frame.

[0038] The scraper is used to move the wood on the inner wall of the upper inclined cylinder or the lower inclined cylinder. When the upper inclined cylinder or the lower inclined cylinder rotates, the scraper scrapes the material attached to the inner wall along the inner wall, which can further prevent the vibrating screen from being blocked during operation.

[0039] The working principle of this embodiment is the same as that of Embodiment 1.

[0040] Example 6

[0041] The difference between this embodiment and embodiment 5 is that the scraper is arc-shaped. The scraper is arc-shaped, with the same curvature as the inner wall of the lower inclined cylinder or the upper inclined cylinder, which helps to more effectively scrape the material on the cylinder wall and reduce the accumulation of materials.

[0042] The working principle of this embodiment is the same as that of Embodiment 1.

[0043] In summary, the utility model can effectively prevent blockage of wood during screening in the upper inclined cylinder and the lower inclined cylinder by arranging the upper roller rod and the lower roller rod to rotate the upper inclined cylinder or the lower inclined cylinder respectively, so that the screener can work continuously and the efficiency of wood screening is improved.

[0044] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of explanation and illustration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention.
