Smaller materials fall through the sieve holes formed between adjacent rollers and the screen discs, achieving particle size screening. Chinese utility model patent CN207478935U discloses a waste disc screen, including a first roller and a second roller arranged adjacent to each other. A first adjusting disc is fixed on the first roller, and a second adjusting disc is fixed on the second roller. Screen holes for waste material are formed between the outer edges of adjacent first and second adjusting discs facing each other. When the first and second adjusting discs rotate synchronously under the influence of the first and second rollers respectively, the distance between the screen holes remains constant.

[0003] However, existing decoration or construction waste treatment equipment suffers from problems such as low sorting efficiency, dust pollution, waste transfer, and solid-liquid mixing. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6This utility model discloses a disc-type sorting device for decoration or construction waste, including several stepped boxes 1, with adjacent stepped boxes 1 internally connected. Each stepped box 1 is equipped with a disc screen assembly for sorting decoration or construction waste. Each stepped box 1 is also equipped with a dust collection component. An inclined plate 2 is fixedly connected between the interiors of adjacent stepped boxes 1. Each stepped box 1 has a discharge port 3 on one side for discharging the sorted decoration or construction waste. Each stepped box 1 is also equipped with a water spray pipe 4, the inlet of which is connected to an external water supply device. Each stepped box 1 has a solid-liquid separation component at its bottom for separating liquid and solid decoration or construction waste.

[0023] Specifically, the disc screen assembly includes a drive motor 5, a gearbox 6, and a rotating rod 7. The drive motor 5 is fixedly connected to the side of the stepped box 1 away from the discharge port 3 via a connecting plate 8. The gearbox 6 is fixedly connected to the output shaft of the drive motor 5 and is fixedly connected to the surface of the stepped box 1. The gearbox 6 has an even number of output shafts, each of which is fixedly connected to a rotating rod 7. The rotating rod 7 is set inside the stepped box 1 via a connecting bearing. Each rotating rod 7 has a disc 9 on its surface, and the discs 9 on two adjacent rotating rods 7 face opposite directions.

[0024] In this embodiment, the gearbox 6 can drive the rotating rod 7 to rotate via the drive motor 5, thereby achieving sorting.

[0025] Specifically, the dust collection component includes a vacuum cleaner 10, which is fixedly connected to the top of the stepped box 1. The suction end of the vacuum cleaner 10 is fixedly connected through the top of the stepped box 1 and extends into the interior of the stepped box 1. An air inlet pipe 12 is fixedly connected to one side of the stepped box 1 through a valve 11.

[0026] In this implementation plan, dust generated during the waste sorting process can be extracted by the suction fan 10. For effective ventilation, valve 11 is opened to connect the outside world with the inside of the stepped box 1 through the air inlet pipe 12. However, if the dust is very heavy, it can be suppressed by spraying water through the water spray pipe 4.

[0027] Specifically, the solid-liquid separation component includes a separation sieve plate 13, which is fixedly installed at the bottom of the disc screen assembly. The separation sieve plate 13 is inclined towards the discharge port 3, and the side of the separation sieve plate 13 closest to the discharge port 3 is flush with the bottom of the discharge port. The solid-liquid separation component also includes a liquid storage tank 14, the bottom of which is parallel to the separation sieve plate 13. A leakage valve 15 is fixedly connected to the surface of the liquid storage tank 14.

[0028] In this embodiment, the liquid present in the waste will be separated into solid and liquid by the action of the separation screen plate 13, and the liquid can be discharged through the leakage valve 15.

[0029] Specifically, an air heater 16 is fixedly connected to the side of the liquid storage tank 14 away from the leakage valve 15. The air inlet of the air heater 16 is connected to an external air supply device, and the air outlet is fixedly connected through the liquid storage tank 14 and extends into the interior of the liquid storage tank 14.

[0030] In this embodiment, in order to prevent residual liquid from corroding the internal structure, gas is added to the air heater 16 through an external air supply device, and at the same time the suction fan 10 is started, but the valve 11 is closed, so that the hot air moves from bottom to top to dry the internal structure.

[0031] Specifically, a material scraper plate 17 is connected to the surface of the separating screen plate 13, and a push-pull rod 18 is fixedly connected to the surface of the material scraper plate 17. The push-pull rod 18 moves through the stepped box 1, and a locking rod component is provided between the push-pull rod 18 and the stepped box 1.

[0032] Specifically, the locking rod component includes a T-shaped post 19, and a limiting ring 20 is fixedly connected to the surface of the step box 1. The T-shaped post 19 moves from top to bottom through the push-pull rod 18 and is movably connected to the limiting ring 20.

[0033] In this embodiment, the T-shaped post 19 is pulled out, disengaging it from the limiting ring 20 and the push-pull rod 18. The push-pull rod 18 is movably connected to the stepped box 1. Specifically, a hole or ring can be made in the stepped box 1, with the inner diameter of the hole or ring being larger than the diameter of the push-pull rod 18. Pulling the push-pull rod 18 back and forth allows the scraper plate 17 to clean up any remaining waste.

[0034] The working principle and usage process of this utility model are as follows: During use, construction or renovation waste enters from the entrance of the first stepped bin 1. As described in Chinese utility model publication CN207478935U, two adjacent rotating rods 7 rotate synchronously, and the construction or renovation waste is screened through the gap between the two discs 9. The falling construction or renovation waste lands on the separating screen plate 13, whose aperture is smaller than the gap between the discs 9, and can only be discharged through the discharge port 3. The inclined separating screen plate 13 facilitates automatic discharge under gravity.

[0035] When some waste remains on the separating screen plate 13 that has not been automatically discharged, it can be cleaned using the scraper plate 17. The T-shaped column 19 is pulled out, disengaging it from the limiting ring 20 and the push-pull rod 18. The push-pull rod 18 is movably connected to the stepped box 1; specifically, holes or rings can be made in the stepped box 1, with the inner diameter of the holes or rings larger than the diameter of the push-pull rod 18. Pulling the push-pull rod 18 back and forth allows the scraper plate 17 to clean the remaining waste.

[0036] Liquids present in the waste will undergo solid-liquid separation under the action of the separating screen plate 13. Dust generated during the waste sorting process can be extracted by the suction fan 10. For effective ventilation, valve 11 is opened to connect the outside world with the inside of the stepped box 1 through the air inlet pipe 12. However, if the dust is very heavy, it can be suppressed by the water spray pipe 4.

[0037] After the waste is processed, in order to prevent the residual liquid from corroding the internal structure, gas is added to the air heater 16 through the external air supply equipment. At the same time, the suction fan 10 is started, but the valve 11 is closed, so that the hot air moves from bottom to top to dry the internal structure.
