Description

Technical Field

[0001] The present application relates to the technical field of decoration waste treatment, and in particular to a decoration waste treatment process. Background Art

[0002] Renovation waste generally includes bricks, concrete blocks, wood blocks, wood shavings, ash, waste ceramics, waste hardware and waste items. Among them, bricks and concrete blocks account for a large proportion and can be used to produce recycled aggregates. Wood blocks, boards, plastics, etc. can be used to make waste-derived fuel, namely RDF, and scrap metals can be recycled.

[0003] The existing RDF production process is relatively simple, usually directly crushing the combustibles and then directly extruding them into shapes; but since the combustibles will be mixed with a small amount of non-combustibles after crushing, such as ash, stones, gypsum, metal, etc., if they are directly used for extrusion molding, the molding effect of the waste-derived fuel will be poor, even if such crushed materials burn faster during combustion, the utilization rate will be reduced.

[0004] Based on this, people put the crushed combustibles into a friction cleaning machine for cleaning, so as to throw the dust on the surface of the combustible materials to the inner wall of the friction cleaning machine, thereby cleaning the combustible materials; but after the friction cleaning machine is used for a long time, the dust accumulates on the inner wall of the friction cleaning machine, so the friction cleaning machine needs to be shut down to clean the dust, which reduces work efficiency.

[0032] After the initial crushing of the combustible materials, the scrap metals buried in the combustible materials are exposed to the outside world. At this time, the scrap metals are sorted to further improve the utilization of decoration waste.

[0033] S3, secondary crushing the impurity-removed combustible material to form combustible fragments, the particle size of the combustible fragments is 500um-2mm; the particle size of the secondary crushed combustible is small, and when an adhesive is added to the secondary crushed combustible, the contact area between the adhesive and the combustible material can be increased, thereby improving the extrusion molding effect of the combustible material.

[0034] S4, pouring the secondary crushed combustible material into the stirring device, and adding adhesive into the stirring device at the same time, the stirring device can fully mix the combustible material and the adhesive, thereby improving the combustible extrusion effect.

When the scraper 33 is located on the upper wall of the mixing barrel 2, the dust scraped by the scraper 33 falls onto the upper surface of the baffle 36; and then the scraper 33 is collected when it rotates to the bottom wall of the mixing barrel 2; the situation where dust falls into the inside of the sieve drum 5 is reduced, and the cleaning effect of combustible fragments is further improved.

[0039] Reference Figure 2The movable component 32 includes a screw rod 321 and a first motor 322.

[0042] Reference Figure 5 In this embodiment, a brush 37 is provided on one side of the first ring 311 close to the outer wall of the sieve drum 5. When the position of the first ring 311 changes in the mixing barrel 2, the brush 37 can clean the sieve holes 52 of the sieve drum 5 to reduce the blockage of the sieve holes 52, so that the dust cleaned by the stirring mechanism 4 for the combustible material can be thrown out from the sieve holes 52 to the inner wall of the mixing barrel 2, thereby improving the cleaning effect of the device on the combustible material.

[0043] Reference Figure 7 A collecting box 6 is installed at the bottom of the mixing barrel 2, and the collecting box 6 is divided into a collecting chamber 62 by a plurality of partition plates 61; the mixing barrel 2 is provided with a plurality of collecting ports 23 respectively connected with the collecting chamber 62; the mixing barrel 2 is hinged with a cover plate 24, and a torsion spring is arranged at the hinge between the cover plate 24 and the mixing barrel 2, and the torsion spring drives the cover plate 24 to normally cover the surface of the collecting port 23 under the elastic force, thereby reducing the dust entering the collecting chamber 62 from re-entering the mixing barrel 2.

The stirring main shaft 41 is rotatably connected to both sides of the stirring barrel 2 in the length direction. The friction blades 42 are provided in multiple groups. All friction blades 42 are installed on the stirring shaft main shaft and are arranged at intervals along the length direction of the stirring main shaft 41. The driving assembly 43 drives the stirring main shaft 41 to rotate. When cleaning the combustible material, it is introduced into the screen drum 5 of the stirring barrel 2. The driving assembly 43 drives the stirring main shaft 41 to rotate.

The outer walls of the first pulley 45 and the second pulley 46 are jointly wound with the belt 47. The second motor 44 is mounted on the stirring barrel 2 to drive the second pulley 46 to rotate. When the second motor 44 is driven, the first pulley 45 and the second pulley 46 rotate simultaneously, thereby driving the stirring main shaft 41 to rotate.

[0047] Reference Figure 1 The mixing barrel 2 is provided with a protective cover 26, and the first pulley 45 and the second pulley 46 are both covered in the protective cover 26, which reduces the possibility of workers accidentally touching the belt 47 and causing injuries, and has a protective effect.
