Description

Technical Field

[0001] The present invention relates to a garbage disposal system, and particularly to a rotary separator for garbage classification. Background Art

[0002] An automatic garbage collection system is a pneumatic garbage conveying system that can transport municipal solid waste through a reticulated steel pipe channel at high speed into a sealed collection bin, and then be transported to a landfill or a garbage transfer station by vehicle. This innovative and modern garbage management system solves the garbage collection problem in any type of building by combining the following gravity or full vacuum methods.

[0003] Generally, there is a gravity-type discharge door on each floor, which are located on the same vertical shaft of a multi-story building. These discharge doors are connected by pipes or shafts. The stainless steel pipes or shafts will be provided with garbage storage nodes and discharge valves for periodically releasing the garbage in the garbage storage nodes. A garbage storage section is arranged directly above the discharge valve to temporarily store the garbage discarded from the garbage shaft.

[0004] A garbage collection bin for collecting garbage will be arranged at the end of the pipe. The garbage collection bin is communicated with the pipe to collect the garbage in the garbage conveying system. The garbage is separated before collection to enter different garbage collection bins, and the amount of manual sorting tools is very large. There are improvements in the prior art. Summary of the Invention

[0005] To solve the above technical problems, the present invention proposes a rotary separator for garbage classification. The garbage entering from the feed port is separated by the high-speed rotation of the rotating body in the separation device and the cooperation of the filter screen. The high-speed rotating rotating body has an adsorption effect, and this adsorption effect cooperates with the filter screen to strip the smaller garbage from the garbage. The larger garbage falls to the material discharge port due to the action of gravity, thereby realizing the separation of different sizes of garbage in the garbage and improving the garbage separation efficiency and reducing the manual input.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A rotary separator for garbage classification includes a separator main body. The separator main body is provided with a feed port and a material discharge port. A separation device is arranged inside the separator main body. The separation device includes a negative pressure connection port, a columnar filter screen, and a rotating component arranged inside the columnar filter screen. The rotating component includes a rotating body, a rotating shaft, and a motor. The rotating body is coaxially arranged inside the columnar filter screen. The motor drives the rotating shaft to rotate, and the rotating shaft is fixedly connected to the rotating body. A spiral blade extending to the material discharge port is arranged below the columnar filter screen, and the spiral blade abuts against the inner wall of the separator main body.

[0007] By adopting the above technical solution, the separation of the garbage entering from the feed inlet is achieved through the high-speed rotation of the rotating body in the separation device and the cooperation of the filter screen. The rotating body with high-speed rotation has an adsorption effect. This adsorption effect cooperates with the filter screen to strip the smaller garbage from the garbage, and the larger garbage falls to the blanking port due to the action of gravity, thereby realizing the separation of garbage of different sizes in the garbage, improving the separation efficiency of the garbage, and reducing the manual input.

[0008] The present invention is further configured that: the rotating body is arranged in a conical shape, including a top end, an inclined surface, and a bottom end, and the bottom end of the rotating body is arranged close to one side of the blanking port.

[0009] By adopting the above technical solution, the rotating body arranged in a conical structure can evenly distribute the garbage of different weights on the rotating body due to different linear velocities, and can avoid throwing the larger garbage into the negative pressure connection port during the adsorption process.

[0010] The present invention is further configured that: the bottom edge of the rotating body extends to the columnar filter screen.

[0011] By adopting the above technical solution, the larger-quality garbage can impact on the columnar filter screen, and the larger-quality garbage can be changed into smaller-quality garbage through collision to be sucked into by the negative pressure connection port.

[0012] The present invention is further configured that: the separator main body includes a separation bin and a blanking bin, the separation bin and the blanking bin are separately arranged, and the spiral blade penetrates through the separation bin and the blanking bin.

[0013] By adopting the above technical solution, the separately arranged separation bin and blanking bin are convenient for the maintenance and installation of the spiral blade and the separation device in the separator main body.

[0014] The present invention is further configured that: the position of the feed inlet is located in the separation bin, the columnar filter screen is flush with the height of the feed inlet, and the height of the negative pressure connection port is higher than the height of the feed inlet.

[0015] By adopting the above technical solution, the garbage in the feed inlet is sucked into the separation bin due to the negative pressure generated by the negative pressure connection port, and the heavier garbage falls into the blanking bin due to gravity. Since the negative pressure interface is higher than the height of the feed inlet, it is avoided that the larger garbage directly enters the negative pressure connection port.

[0016] The present invention is further configured that: the rotation speed of the rotating body is 1000 - 3000 r / min.

[0017] By adopting the above technical solution, it can realize the stripping of smaller garbage of different qualities.

[0018] The present invention is further configured such that: a belt drive is employed between the motor and the rotating shaft.

[0019] By adopting the above technical solution, the belt is elastic, which can buffer impacts, reduce vibrations, and provide smooth transmission. When the transmission components encounter obstacles or overload, the belt slips, causing the rotational speed of the rotating body to decrease, making it easier for the negative pressure connection port to suck in the garbage attached to the surface of the rotating body.

[0020] The present invention is further configured such that: the cylindrical filter screen includes a first flange and a second flange arranged oppositely, a filter screen body is arranged between the first flange and the second flange, and the second flange is fixedly connected to the rotating member.

[0021] By adopting the above technical solution, the rotation of the cylindrical filter screen is realized through the second flange, and the peeling effect on different types of garbage is improved by the rotating filter screen body, and larger garbage can be broken into smaller garbage to improve the separation effect.

[0022] The present invention is further configured such that: the cylindrical filter screen is coaxially arranged with the spiral blade.

[0023] By adopting the above technical solution, the garbage after impact can be evenly distributed on the spiral blade, avoiding blockage caused by excessive garbage passing through the material dropping port at the same time.

[0024] In summary, the present invention has the following effects:

[0025] 1. The separation of the garbage entering from the feeding port is realized through the high-speed rotation of the rotating body in the separation device and the cooperation of the filter screen. The high-speed rotating rotating body has an adsorption effect, and this adsorption effect cooperates with the filter screen to peel off the smaller garbage in the garbage. The larger garbage falls to the material dropping port due to the action of gravity, thereby realizing the separation of different sizes of garbage in the garbage, improving the separation efficiency of the garbage, and reducing the manual input.

[0026] 2. The rotation of the cylindrical filter screen in the separator main body is realized through the second flange, and the crushing effect on the garbage is improved by the high-speed rotating cylindrical filter screen, and the separation effect on the garbage is improved.
