Embodiment 1

[0037] An equipment for preparing combustible garbage fuel rods, including a feeding device, a crushing device, an extrusion device, an exhaust gas purification system and an electrical control system; wherein

[0038] The feeding device is a lifting belt conveyor 1, and one side of the lifting belt conveyor 1 is arranged above the raw material hopper 3 in the dust-proof box 2;

[0039] The crushing device is a double-toothed roller crusher, which mainly includes: a crushing motor, a reduction box, a gear box, a dust-proof box, a raw material bucket, a base, and a frame; the gear box 4 is provided with a first crushing roller that rotates in opposite directions The wheel 5 and the second crushing roller 6 are respectively connected with the first reduction box 7, the first crushing motor 8, the second reduction box 9 and the second crushing motor 10 on both sides of the gear box in turn; the upper part of the gear box is provided with raw materials Bucket 3, a dustproof box 2 ...

Embodiment 2

[0043] A preparation method of combustible garbage fuel rod:

[0044] (1) After the combustible garbage is dried or aired to a moisture content of 10%, it is transported to the raw material hopper of the double-toothed roller crusher by the lifting belt conveyor. dust pollution;

[0045] (2) The two round rollers in the double-toothed roller crusher rotate in opposite directions, and the combustible garbage is rolled into the crushing cavity formed by the two rollers and crushed into fragments with a particle size of 4cm; under the action of gravity, the crushed garbage is Discharge from the gap between the two rollers into the extruder feed hopper;

[0046] (3) The garbage in the feeding hopper enters the feeding cavity under the transmission of the spiral blade on the feeding screw, and then falls from the feeding cavity to the feeding end of the extrusion barrel to realize the transmission of garbage in batches and reduce extrusion. Accumulation and blockage of materials ...

Embodiment 3

[0051] Actual usage description:

[0052] The combustible garbage after garbage classification in a district of Tianjin is mainly composed of plastic bags, plastic bottles, plastic ropes, old fabrics, cartons, waste rubber, etc. After drying to a moisture content of 15%, the method and device of the present invention are used to process the fuel rod. The combustible garbage is transported to the raw material hopper of the double-toothed roller crusher by the lifting belt conveyor, and crushed into pieces with a particle size of 3cm. Then it enters the feed hopper of the single screw extruder, the screw speed of the extruder is set to 30 rpm, the temperature of the waste debris is controlled to rise to 120 ° C, the diameter of the discharge port on the cutting die is 3.5 cm, and the cutting knife is cut into pieces. A fuel rod with a diameter of 3.5cm and a length of 10cm.

[0053] Referring to GB / T30727-2014 "Method for Determination of Calorific Value of Solid Biomass Fuel"...

Abstract

The invention discloses a method and equipment for preparing a high-density fuel rod by rapidly reducing combustible refuse. The device comprises a feeding device, a crushing device, an extruding device, a waste gas purifying system and an electrical control system. The invention provides a method and equipment for preparing a high-density fuel rod by quickly reducing combustible refuse, mainly aiming at a series of problems that the combustible refuse is loose in volume, not easy to store and transport, low in calorific value per unit volume and the like, and the combustible refuse is prepared into a rod-shaped structure which is convenient to transport and use. The method has the technical advantages of simple process, suitability for large-scale production, low cost, no secondary pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of combustible garbage resource utilization, and in particular relates to a method and equipment for rapidly reducing the weight of combustible garbage to prepare high-density fuel rods. Background technique [0002] Combustible garbage refers to the garbage that can be burned, including plant garbage, waste paper that is not suitable for recycling, waste plastic and rubber, old fabrics, waste wood, etc. Incineration is one of the main methods of dealing with combustible garbage. Through appropriate thermal decomposition, combustion, melting and other reactions, combustible garbage is oxidized under high temperature conditions, eliminating various pathogens, converting toxic and harmful substances into harmless substances, and finally becoming Residues or molten solid materials are landfilled and recycled to realize the reduction, harmlessness and recycling of garbage. [0003] Combustible garbage is loose ...
