[0001] The present invention relates to the technical field of resource recovery, and in particular to a dry-type separation medium secondary recovery device and a recovery method. Background Art

[0002] Among existing material sorting technologies, wet separation of light and heavy materials is widely used in certain applications due to its ease of operation. However, wet separation of light and heavy materials has problems such as high water consumption, complex post-processing, and environmental pollution.

[0003] When the existing dry sorting equipment is in use, after the medium receives the gas jet to form a fluidized gas chamber, the vibration of the excitation device can separate the recyclable materials into layers, which is convenient for the recovery of light and heavy materials. However, the light and heavy materials after sorting will adhere to the medium, so that the medium will be taken out during the recovery, resulting in waste of the medium. The medium cannot be recovered to the maximum extent. This part of the lost medium becomes the main source of loss of the sorting medium, increasing economic losses. Summary of the Invention

[0004] Based on the technical problem that existing dry sorting equipment will carry out the medium together, resulting in waste of the medium, the medium cannot be recovered to the maximum extent, and this part of the lost medium becomes the main source of loss of the sorting medium, increasing economic loss, the present invention proposes a dry sorting medium secondary recovery device and recovery method.

[0005] The present invention provides a dry-type separation medium secondary recovery device and recovery method, which include a separation component, a recovery device and a conveying device installed on the outer surface of the separation component.

[0006] The recovery device is located on the outer side of the sorting component and recovers the medium contained in the light matter and heavy matter after sorting. The recovery device includes a light matter medium collection chamber, which collects the medium contained in the light matter.

[0007] The conveying device is located on the outer surface of the recovery device and conveys the medium collected by the recovery device to the sorting component. The conveying device includes a conveying scraper. The movement of the conveying scraper scrapes the medium collected in the recovery device and then conveys it.

[0008] Preferably, the recovery device also includes a heavy matter medium collection chamber, the heavy matter medium collection chamber is fixedly installed on the outer side of the base of the sorting component, the light matter medium collection chamber is fixedly installed on the outer side of the base of the sorting component, one end of the heavy matter medium collection chamber is fixedly connected to one end of the outlet of the heavy matter sorting channel of the sorting component, and one end of the light matter medium collection chamber is fixedly connected to one end of the outlet of the light matter sorting channel of the sorting component.

[0009] Through the above technical solution, after the solid recyclables are sorted by the sorting components and separated, they enter the heavy material medium collection chamber and the light material medium collection chamber respectively through the light material sorting channel outlet and the light material sorting channel outlet under the influence of the excitation force, and the separated heavy and light materials can be transported and collected.

[0011] Through the above technical solution, under the action of the exciting force, the media contained in the light matter and heavy matter can be screened through the medium screen plate and enter the bottom of the heavy matter medium collection chamber and the light matter medium collection chamber.

[0012] Preferably, the conveying device further comprises a medium recovery pipe, one end of which is fixedly connected to the outer side surface of the heavy matter medium collecting chamber, and the other end of which is fixedly mounted to the outer side surface of the sorting component.

[0013] Through the above technical solution, the medium can be recovered through the medium recovery pipeline, and the medium recovery pipeline can transport the recovered medium into the sorting component again for recycling.

[0014] Preferably, the outer side surface of the heavy matter medium collecting chamber is fixedly connected with a communication pipe, and one end of the communication pipe is fixedly connected with the outer side surface of the light matter medium collecting chamber.

[0015] With the above technical solution, the medium in the light matter medium collecting chamber can be transported into the heavy matter medium collecting chamber through the connecting pipe.

[0016] Preferably, an inclined plate is fixedly mounted on the inner wall of the heavy matter medium collecting chamber, and an aggregation block is fixedly mounted on the outer surface of the inclined plate.

[0017] Through the above technical solution, the inclined plate is inclined, which makes it easy to transport the medium to one end of the gathering block by using the exciting force, and then gather the medium through the gathering block, so that the medium can be scraped by the conveying scraper and then transported.

[0018] Preferably, a driving motor is fixedly mounted on the outer side surfaces of the heavy matter medium collection chamber and the medium recovery pipe, and a rotating shaft is rotatably connected to the inner walls of the heavy matter medium collection chamber and the medium recovery pipe through bearings, one end of the rotating shaft is fixedly mounted to one end of the output shaft of the driving motor, a synchronous wheel is fixedly mounted on the outer surface of the rotating shaft, and a synchronous belt is rotatably connected to the outer surface of the synchronous wheel.

[0019] Through the above technical solution, the rotation of the driving motor drives the rotating shaft to rotate, and the rotation of the synchronous wheel drives the synchronous belt to rotate. The synchronous belt is set along the shape of the medium recovery pipe, which facilitates the rotation of the conveying scraper into the medium recovery pipe, so that the conveying scraper fits the medium recovery pipe.

[0020] Preferably, a limit clamp is fixedly installed on the inner wall of the heavy material medium collection chamber, one end of the limit clamp is fixedly installed on the inner wall of the medium recovery pipe, and a limit rod with a ball is fixedly installed on the outer side of the synchronous belt, and the outer surface of the ball of the limit rod is slidably connected to the outer side of the limit clamp.

[0021] Through the above technical solution, the synchronous belt can be limited by the limiting clamp ring, so that the synchronous belt can match the shape of the medium recovery pipe, thereby facilitating the movement of the conveying scraper.

[0024] The present invention proposes a recovery method of a dry separation medium secondary recovery device, comprising the following steps:

[0025] S1: The light matter discharged from the outlet of the light matter sorting channel in the sorting component and carrying a small amount of medium enters the light matter medium collecting chamber under the action of the exciting force. After being screened by the medium screen plate, the medium is located on the upper surface of the inclined plate of the light matter medium collecting chamber. The medium recovered under the action of the exciting force enters the heavy matter medium collecting chamber through the connecting pipe, and the light matter on the light matter medium collecting chamber is discharged through the outlet.

[0026] S2: The heavy matter discharged from the outlet of the heavy matter sorting channel in the sorting component and carrying a small amount of medium is transferred to the heavy matter medium collecting chamber for secondary recovery under the action of the exciting force. The small amount of medium is recovered to the inclined plate in the heavy matter medium collecting chamber below the medium sieve plate under the action of the vibrating screening device, while the heavy matter is located above the heavy matter medium sieve plate and discharged through the outlet. The small amount of medium in the heavy matter medium collecting chamber and the light matter medium entering the heavy matter medium collecting chamber through the connecting pipe are gathered by the gathering block and are located at the bottom of the inclined plate.

[0027] S3: The driving motor drives the rotating shaft to rotate, which drives the synchronous wheel to rotate, and then drives the synchronous belt to rotate, and then drives the conveying scraper to deflect along with the synchronous belt. The ball on the limiting rod of the synchronous belt rotates on the outer side of the limiting clamp ring. At the same time, the limiting clamp ring limits the conveying scraper, so that the conveying scraper drives the scraped medium into the medium recovery pipe, rises, and then is conveyed to the other end of the medium recovery pipe. After passing through the inclined shape of the other end of the medium recovery pipe, the medium can slide into the sorting component.

[0028] The beneficial effects of the present invention are:

[0029] 1. By setting up a recovery device, the medium contained in the light material and the heavy material can be recovered. By adding a light material medium collection chamber and a heavy material medium collection chamber, the light material and heavy material after sorting can be transported. At the same time, the exciting force can be used to screen the medium on the light material and the heavy material through the medium screen plate, so that the medium passes through the medium screen plate and enters the light material medium collection, thereby reducing the waste of the medium. It solves the problem that the existing dry sorting equipment will take out the medium together, causing waste of the medium. The medium cannot be recovered to the maximum extent. This part of the lost medium becomes the main source of loss of the sorting medium, increasing the economic loss.

[0030] 2. By setting up a conveying device, the recovered medium can be transported to the sorting component. The conveying scraper is driven by the rotation of the synchronous belt to move and scrape the recovered medium, and then transported to the medium recovery pipe of the box. Finally, it enters the sorting component through the inclined end of the medium recovery pipe, so that the collected medium can be recycled, thereby reducing the waste of the medium.
