Description

Technical Field

[0001] This utility model relates to the field of medical waste glass bottle treatment, and in particular to a cylindrical screening machine that can improve screening efficiency. Background Technology

[0002] Medical waste glass bottles consist of a glass bottle body (glass) and a bottle cap (an integral structure consisting of an aluminum cap and a rubber stopper). The medical waste glass processing process includes: first, the glass is fed through a hopper, then conveyed by a belt conveyor to a primary crusher. The primary crusher produces intact bottle caps (an integral structure consisting of an aluminum cap, rubber stopper, and a glass neck) and glass fragments from the broken bottle body. A primary screening machine then removes most of the glass fragments (smaller than the bottle cap), leaving the intact bottle caps (an integral structure consisting of an aluminum cap, rubber stopper, and glass neck) which are fed into a secondary crusher. The secondary crusher produces separated aluminum caps, rubber stoppers, and glass shards (from the broken glass neck). A filter screen at the bottom of the secondary crusher filters out the glass shards. The aluminum caps and rubber stoppers then enter a vortex separator to separate the rubber stopper and aluminum cap. The final products are glass, butyl rubber, and aluminum.

[0003] The existing primary screening machine has relatively low screening efficiency, and glass fragments are not completely separated. Some glass fragments enter the next process along with bottle caps, rubber stoppers, or aluminum caps. This results in low screening efficiency and increases the burden on the secondary crusher's filter screen for filtering glass shards. If separation is incomplete, glass shards may also be carried in the rubber, which will further reduce the quality of the recycled product. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cylindrical screening machine that can improve screening efficiency and prevent glass fragments from continuing to be passed forward to the next process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A cylindrical screening machine that can improve screening efficiency includes a shell, a cylinder installed inside the shell, the cylinder being connected to a rotating shaft, and the rotating shaft being driven to rotate by a drive device; the cylinder is covered with filter holes, and a discharge port is fixed on the shell at the lower end of the cylinder;

[0007] The cylinder is divided into left and right sections. The filter holes in the section located at the input end of the cylinder are small, while the filter holes in the section located at the output end of the cylinder are large.

[0008] The length of a section located on one side of the cylinder's input end is L1, and the length of a section located on one side of the cylinder's output end is L2, where L1 > L2.

[0009] The cylinder at the input end maintains a gap of 1mm-2mm with the inner end wall of the housing, and the cylinder at the output end maintains a gap of 0.6m-0.9m with the inner end wall of the housing.

[0010] The inner wall of the cylinder is fixed with helical blades.

[0011] The cylinder is made of stainless steel.

[0012] The discharge ports include a glass fragment discharge port, a bottle cap discharge port, and a waste discharge port. The length of the upper opening of the glass fragment discharge port is equal to L1, and the length of the upper opening of the bottle cap discharge port is equal to L2.

[0013] The filter holes on the cylinder of length L1 have a diameter of 16mm-18mm; the filter holes on the cylinder of length L2 have a diameter of 40mm.

[0014] This utility model provides a cylindrical screening machine that can improve screening efficiency, and has the following technical effects:

[0015] 1) When the screening efficiency is found to be insufficient, the measures taken in this application are as follows: First, the overall length of the equipment is extended from about 3m to about 4.4m; at the same time, spiral blades are installed inside the cylinder, which extends the screening path, achieves full screening, separates glass fragments, and avoids the defect of glass fragments entering the next process due to unclean screening.

[0016] 2) By dividing the cylinder into left and right sections, with the filter holes of the two sections arranged in two different grades of aperture, and keeping the output end of the cylinder at a distance from the inner end face of the shell, materials of different particle sizes can accurately enter the corresponding screening area, so that the materials are screened out in sequence according to particle size during the screening process. This device can screen three kinds of materials, thereby effectively improving the screening efficiency. Attached Figure Description

[0024] like Figure 1-4 As shown, a cylindrical screening machine that can improve screening efficiency includes a housing 1, inside which a cylinder 2 is installed. The cylinder 2 is connected to a rotating shaft 3, which is driven to rotate by a belt conveyor mechanism 4 and a motor 5. The cylinder 2 is covered with filter holes 6, and a discharge port 7 is fixed on the housing 1 at the lower end of the cylinder 2. A feed hopper 8 is fixed on the housing 1 at the input end of the cylinder 2.

[0025] like Figure 3-4 As shown, preferably, the filter holes 6 are divided into two groups in the direction from the input end to the output end. One group (denoted by a) has a length of L1, and the other group (denoted by b) has a length of L2, and L1>L2. The filter holes 6 in group a are smaller than those in group b. The filter holes 6 in group a are used to filter glass fragments, and the filter holes in group b are used to filter bottle caps (an integral structure consisting of an aluminum cap, a rubber stopper, and a glass bottle neck).

[0026] The primary cylindrical screening machine 5 has three sets of discharge ports 7: a glass fragment discharge port 7.1, a bottle cap discharge port 7.2, and a waste discharge port 7.3. The cylinder 2 on the waste discharge port 7.3 side is spaced a certain distance from the end face of the shell 1. Glass fragments are removed from the glass fragment discharge port 7.1 and collected, while bottle caps fall from the bottle cap discharge port 7.2 and enter the third conveyor 6. Waste (paper and other debris from glass bottles) is too large to be filtered through the filter holes 6 and is finally removed from the cylinder 2 and enters the waste discharge port 7.3, where it is collected by a waste bag.

[0027] like Figure 5 As shown, preferably, the cylinder 2 is connected to the rotating shaft 3 via a connecting rod 9. The inner wall of the cylinder 2 is provided with helical blades 10. By providing the helical blades 10, the material is driven forward and conveyed by the helical blades 10 during the rotation of the cylinder 2.

[0028] Preferably, the diameter of filter hole 6(a) is smaller than the diameter of filter hole 6(b).

[0029] The shell 1 of this device is 4.4 meters long, the front section of the cylinder 2 (screen) is 2.5 meters long (L1), and the aperture of its filter hole 6 is 18 mm. The rear section of the cylinder 2 (screen) is 1 meter long (L2), and the aperture of its filter hole 6 is 40 mm.

[0030] Working principle and process:

[0031] During operation, the bottle caps (composed of an aluminum cap, rubber stopper, and glass neck) and glass fragments from the broken bottle body are obtained after being crushed by the primary crusher. These materials are conveyed into the feed hopper 8 and then into the cylinder 2. The motor 5 starts and drives the rotating shaft 3 to rotate via the belt conveyor 4. The rotating shaft 3 drives the cylinder 2 to rotate. The glass fragments are filtered out through the filter holes 6 at the front end and exit through the glass fragment outlet 7.1. As the material continues to be conveyed forward, the complete bottle caps fall from the bottle cap outlet 7.2; the remaining waste is removed from the waste outlet 7.3.
