The recycling of the refuse derived fuel brings the vitality for the energy regeneration of the refuse. The high-calorific-value substances separated from the garbage, such as sludge, textiles, wood fibers, rubber, leather and the like, are subjected to crushing, mixing, extrusion forming and other treatment processes to prepare the solid fuel rod. The garbage derived fuel is prepared by pretreating and shaping domestic garbage effectively.

In actual life, people rarely discard the garbage according to classification prompts, and the garbage is stacked in the empty space before fuel is made. When in manufacturing, the garbage is scooped up by a shovel and poured into the manufacturing device. Therefore, impurities such as stones are easily mixed in the refuse put into the refuse derived fuel apparatus. At present, the domestic garbage separator has low mechanization degree and low garbage separation rate, and the manual garbage separation can use excessive manpower. Further, the garbage disposal system cannot work normally, and the quality of the manufactured fuel has problems.

Detailed Description

The embodiment of the invention provides a solid waste refuse derived fuel forming system, which comprises a support 1, a forming pipe 2, a crushing device 3, a first box body 4, a pipeline 5 and a second box body 6, as shown in figures 1-6. The center of the bracket 1 is welded with the forming tube 2. The forming pipe 2 vertically penetrates through the support 1, a discharge hole of the crushing device 3 is welded with one side of the forming pipe 2, and the box body I4 is welded on one side of the crushing device 3. As can be seen from the attached drawing 3, a conveyor belt 7 is fixedly arranged on the first box body 4 and the crushing device 3, the conveyor belt 7 is arranged in an inclined mode, the lower end of the conveyor belt 7 extends into the first box body 4, and the upper end of the conveyor belt 7 extends out of the first box body 4 and is fixedly arranged on the top of the first box body 4.

The upper end of the conveyor belt 7 corresponds to the feed inlet of the crushing device 3, and the upper end of the conveyor belt 7 is positioned right above the feed inlet of the crushing device 3. The waste falls from the upper end of the conveyor belt 7 into the crushing device 3 as it is transported upwards by the conveyor belt 7. Since the "crushing device" has been disclosed in chinese patent net, patent No. 201580069453.2. The crushing device 3 is not innovated in the scheme, so the crushing device 3 is a conventional technical means, and the specific structure, the connection mode and the like are the same as those of the prior art and are not described in detail.

The top of the first box body 4 is welded with a pipeline 5, and the upper end of the pipeline 5 is welded with the bottom of the second box body 6. The first box body 4 is communicated with the second box body 6 through a pipeline 5. The inner diameter of forming tube 2 decreases downward. The forming tube 2 is internally pivoted with a rotating shaft 21, the surface of the rotating shaft 21 is welded with a spiral fan blade 22, the top of the forming tube 2 is fixedly provided with a motor 23, and a transmission shaft of the motor 23 is welded with the rotating shaft 21. The motor 23 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the spiral fan 22 to rotate, so as to extrude the garbage entering the forming pipe 2. The garbage moves downwards along the track of the spiral fan blades to finally form a columnar fuel rod which is pushed out from the lower end of the forming pipe 2.

The bottom of the inner wall of the first box body 4 is provided with a slope 41, a plurality of air pipes 43 are fixedly arranged in the first box body 4 along the slope 41, and the surfaces of the air pipes 43 are provided with air holes 431. An air pump 48 communicated with the air pipe 43 is welded on the outer wall of the first box body 4. Leading-in groove 49 has all been seted up to box 4 inner wall front and back both sides, and box 4 has shovel board 44 through leading-in groove 49 sliding fit, and box 4 outer wall fixed mounting has big electric push rod 47. The movable end of the large electric push rod 47 is welded with the shovel plate 44. The movement of blade 44 is achieved by large electric push rod 47 telescoping. A water inlet pipe 45 is welded on one side of the first box body 4, the water inlet pipe 45 is located at the highest position of the slope 41, and a water outlet pipe 46 is welded on the other side of the first box body 4.

During operation, water is continuously injected into the first box body 4 through the water inlet pipe 45 and flows out of the water outlet pipe 46. The lower half of blade 44 is always submerged. When the garbage falls into the first box body 4, the water flows out from the water inlet pipe 45 to push the garbage to move to the other side of the first box body 4. Meanwhile, the air pump 48 continuously sends air into the air pipe 43 to make the water generate bubbles continuously. Most of the raw materials of refuse derived fuel are textiles, wood fibers, leather, etc. Therefore, these materials are light in weight and, after being immersed in water, rise in bubbles to contact the raw materials and drive them to float on the water surface. The weight of the stones and the metal objects is heavy and the stones and the metal objects sink directly. The large electric push rod 47 is then retracted to bring the blade 44 closer to the conveyor belt 7, pushing the raw material onto the conveyor belt 7. The conveyor belt 7 is transported upwards and eventually the raw material falls into the crushing device 3.

Since the fuel is composed of combustible substances, and the fuel is formed through continuous extrusion. The heat generation through friction easily causes the raw material to burn in the forming tube 2. Therefore, the raw material is not easy to reach the ignition point after being soaked in water, and plays a role in protection.

Referring to the attached figure 2, an inclined plate 61 is welded on the left side of the inner wall of the second box body 6, a roller 62 is pivoted in the inclined plate 61, and the roller 62 is made of an iron material. An electromagnet 63 is fixedly installed in the roller 62. The drum 62 is driven by a motor, and the detailed structure, circuit arrangement, etc. are not described in detail since the electromagnet 63 is a prior art. And a scraper 64 is welded at the bottom of the inner wall of the second box body 6, the scraper 64 vertically and upwards contacts the right side of the roller 62, and the right side of the bottom of the support 1 is clamped with a receiving groove 65.

When the garbage collecting device works, the roller 62 rotates, the electromagnet 63 in the roller 62 is electrified to generate magnetic force, the surface of the roller 62 generates magnetic force, and garbage slides down along the inclined plate 61 to be in contact with the roller 62. Because the surface of the roller 62 is provided with magnetic force, part of metal in the garbage is absorbed by the roller 62, and the absorbed metal is scraped off by the scraper 64. The purpose of primary screening is achieved.
