Description

Technical Field

[0001] This utility model relates to the field of waste sorting, and in particular to a new type of high-efficiency sorting machine for mixed materials. Background Technology

[0002] With the advancement of urbanization and industrialization, an increasing amount of waste is generated, such as household waste, sanitation waste, construction waste, and renovation waste. The country is vigorously promoting waste recycling and sorting to achieve resource reuse. Centralized collection of mixed waste or mixed waste that has undergone initial crushing includes: small-sized heavy materials, light materials (lightweight plastics, paper, wood chips or small fragments, etc.), and dust. Currently, mixed materials are directly fed into multi-stage sorting and screening, which has the following drawbacks: First, the excessive dust at the sorting site creates a poor production environment, shortens the lifespan of machines, increases equipment failure rates, and affects workers' health. Second, the heavy materials are mixed with a large amount of light materials and dust, resulting in poor screening accuracy and low purity of the screened material, making it unsuitable for direct reuse. Third, light materials easily clog the screens, requiring frequent maintenance and resulting in low production efficiency. Utility Model Content

[0003] To address one or more of the aforementioned problems, this utility model provides a novel high-efficiency sorting machine for mixed materials.

[0004] According to one aspect of the present invention, a novel high-efficiency separator for mixed materials includes: a heavy material primary separator, a light material separator, a cleaning and unblocking section, and an airlock unloader.

When the pressure difference between the settling shell and the drain pipe is higher than the standard value, the differential pressure controller controls the initial motor to stop and controls the cleaning rotating part and the unblocking fan to start, so as to perform cleaning, unblocking and dust removal.

[0010] In some embodiments, the lower end of the light material outlet pipe is fixedly installed inside the annular shell of the airlock unloader, and the rotating shaft of the rotating wheel module is rotatably connected inside its cylindrical cavity. The initial distribution motor is installed on the side wall of the annular shell, and the loading cavity of the rotating wheel module is attached to the inner wall of the annular shell.

[0011] In some embodiments, the rotary module also includes several pressure plates and V-shaped support ribs.

[0012] The elastic strip is located between the pressure plate and the radial partition plate, and the three are connected by threaded parts; at least two support ribs are fixedly connected to the lower ends of two adjacent radial partition plates.

[0014] The initial motor is a hollow shaft variable frequency geared motor. The initial motor is electrically connected to the torque monitoring unit. The shock-absorbing column at the lower end of the initial motor is connected to the motor base, and the motor base is threaded to the lower end of the mounting bracket.

[0015] In some embodiments, the cleaning motor of the cleaning rotating part is fixedly connected to the side frame of the settling shell via a coupling seat, the second seated bearing is fixedly connected to the side frame, the outer end of the cleaning rotating shaft is directly connected to the cleaning motor, the intermediate shaft sleeve is the second seated bearing, and its inner end plate is threadedly connected to the center end block of the inner end plate of the circular frame, and the inner hole of the center end block is hinged to the lateral center seat of the inner cylinder surface of the core cylinder through a bearing.

[0016] In some embodiments, a fixed slip ring is provided at the inner end of the fixed flange, and the fixed slip ring is connected to the movable slip ring at the outer end of the circular ring skeleton by a rotating shaft sleeve.

The lower end of the cleaning head has a rectangular array of several elongated hole-shaped air holes.

[0019] In some embodiments, the circular frame includes several longitudinal beams and circular stiffeners. The longitudinal beams are arranged in a circumferential array, and the circular stiffeners are equally spaced. Each longitudinal beam is fixedly snapped into a slot on the circular stiffener, thereby forming a three-dimensional circular frame.

[0020] The circular filter screen is formed by multiple arc-shaped unit meshes. Each ring unit mesh has several arc-shaped light material filter holes arranged longitudinally at equal intervals. The arc-shaped unit meshes are welded to the circular frame.

[0021] In some embodiments, the front and rear left sides of both the initial separation shell and the settling shell are provided with observation windows made of transparent material.

[0022] Alternatively, the left end of the first connecting pipe is connected to a deceleration pipe and the right end is connected to a speed-increasing air pipe.

[0023] Alternatively, a speed-increasing nozzle for connecting to a blower may be located on the lower right side of the heavy material outlet.

[0024] This novel high-efficiency separator for mixed materials employs a primary separator with a rotating wheel module for effective separation of heavy materials, and a secondary separator with a filter cartridge for efficient separation of light materials. The rotating part cleans and the cleaning and unclogging part unclogs the filter cartridge, ensuring long-term, clog-free operation and stable, efficient filtration of light materials. Simultaneously, the airlock unloader uses a rotating wheel module for high-sealing continuous unloading, guaranteeing unloading of the light material separator without air pressure loss or clogs. Therefore, this device achieves efficient separation of heavy materials, light materials, and dust from mixed materials. Its advantages are: First, the separation of heavy and light materials results in high purity, maintaining a clean and well-ventilated workshop, ensuring smooth operation of the equipment, extending its service life, and effectively protecting worker health. Furthermore, the high purity of each stage of material facilitates recycling. Second, the cleaning and unclogging part regularly blows air to clean the filter cartridge, preventing material from clogging the separator. This ensures the separator maintains high separation efficiency over the long term, efficiently utilizing energy and reducing maintenance costs by minimizing infrequent maintenance. It also improves equipment efficiency and increases sorting speed. Simultaneously, it requires no additional space for additional equipment, resulting in a compact overall design. Thirdly, the heavy material separator adopts a rotary wheel structure. Compared to multi-mesh vibrating screens, the radial dividing plate has a higher load-bearing capacity, remains undeformed over long-term use, has a long service life, reduces maintenance and replacement costs, and effectively improves screening efficiency. The circumferentially distributed material-carrying chambers allow for reciprocating feeding and throwing, and the material exits under the influence of gravity and centrifugal force. Heavy materials have greater kinetic energy, making it easier to separate light materials, resulting in high sorting accuracy. Fourthly, the rotary wheel module has a radially elastic V-shaped material-carrying chamber. The elastic strips closely contact and seal the inner wall of the cylindrical body, effectively sealing and isolating the separation chamber and the cylindrical body cavity, preventing airflow leakage caused by intermediate gaps, eliminating dust, improving the working environment, and protecting the machine's service life. Even after the radial dividing plate undergoes slight deformation due to long-term impact loads, the elastic strips provide a buffer space, maintaining close contact and sealing while protecting the cylindrical body from friction damage, ensuring long-term effective sorting. Fifthly, the airlock unloader has several rotatable unloading chambers with elastic interference connections, achieving highly sealed continuous unloading. Attached Figure Description

[0044] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

The rotating shaft 51 of the rotating wheel module 5 is rotatably connected to the front and rear walls of the receiving chamber 100, and its extended end is directly connected to the pre-sorting motor 50. Several radially arranged radial dividing plates 52 are connected to the rotating shaft 51 at their inner ends and to the elastic strips 54 at their outer ends, and are fixed with side cover plates 53 at the front and rear, forming several radially elastic variable fan-shaped material loading chambers 500 that are in close contact with the receiving chamber 100.

The lower end of the light-heavy separation chamber 101 is the heavy material outlet 103, and the upper end is the mixed flow outlet 104 for light materials and dust.

[0047] The airflow passes from bottom to top through the light and heavy separation chamber 101; the initial separation motor 50 drives the rotating wheel module 5 to rotate, the material loading chamber 500 is loaded at the inlet and rotates to the arc-shaped outlet. Under the dual action of gravity and centrifugal force, the material enters the light and heavy separation chamber 101 from the material loading chamber 500 through the arc-shaped discharge port. The heavy material falls from the heavy material outlet 103, and the light material and the mixture fly out from the mixed flow outlet 104 under the action of wind, thus realizing the separation of light and heavy materials.

The outer end of the external air inlet pipe 35 extends out of the settling shell 20 and is connected to the air outlet of the unblocking blower 36. The cleaning rotating section 6 drives the filter cylinder 7 to rotate circumferentially. The unblocking blower 36 is started so that the cleaning head 33 blows the light material on the filter cylinder 7 below into the light material outlet pipe 202 for unblocking.

[0050] The unblocking blower 36, the external air inlet pipe 35, the internal transfer pipe 34, the core cylinder 31, and the cleaning head 33 are interconnected to form a blowing passage. The cleaning rotating part 6 drives the filter cartridge 7 to rotate, and the cleaning head 33 blows away the light material stuck on the filter cartridge 7.

The initial motor 50 is installed on the side wall of the annular shell 41, and the material loading cavity 500 of the rotating wheel module 5 is fitted against the inner wall of the annular shell 41.

[0052] This novel high-efficiency separator for mixed materials employs a heavy material pre-separator 1 with a rotary wheel module 5 to effectively separate heavy materials, and a light material separator 2 with a filter cartridge 7 to efficiently separate light materials. The filter cartridge 7 is rotated via a cleaning rotating part 6, and a cleaning and unclogging part 3 performs unclogging and cleaning, ensuring long-term operation without clogging and maintaining stable and efficient filtration of light materials. Simultaneously, the airlock unloader uses the rotary wheel module 5 for high-sealing continuous unloading, ensuring that the light material separator 2 unloads without air pressure loss or clogging. Therefore, this device achieves efficient separation of heavy materials, light materials, and dust from mixed materials; its beneficial effects are... The results are as follows: First, the separation of heavy and light materials achieves high purity. The production site and subsequent operations involving heavy materials maintain a clean workshop with good air quality, ensuring smooth operation of machinery and equipment, extending their service life, and effectively protecting worker health. Furthermore, the high purity of materials at each stage facilitates material recycling. Second, the cleaning and unblocking section 3 regularly blows air to clean the filter cartridge 7, preventing material blockage in the separator. This ensures the separator maintains high separation efficiency over the long term, efficiently utilizing energy while minimizing the need for frequent maintenance, effectively reducing maintenance costs, and improving equipment efficiency and separation speed.

Fifth, the airlock unloader 4 has an elastic interference connection of several circumferential arrays of unloading chambers 40 that can rotate, realizing high-sealing continuous unloading.
