Description

Technical Field

[0001] The invention relates to the technical field of pyrolysis furnace devices, in particular to a bio-waste pyrolysis and reduction treatment furnace. Background Art

[0002] The treatment of biological waste has become an increasingly serious problem. If biological waste such as kitchen waste, garden waste, and agricultural waste is not properly handled, it will not only take up a lot of space, but also cause serious pollution to the environment.

[0003] Pyrolysis technology refers to heating biowaste to about 400℃-800℃ under oxygen-free or oxygen-deficient conditions, in which biowaste is decomposed into solid residues, liquid products and combustible gases. For solid residues, their volume is greatly reduced, achieving waste reduction treatment, liquid products can be further processed or utilized, and combustible gases can be recycled and used as energy to supply the operation of the treatment furnace itself or for other purposes, thereby reducing treatment costs. However, there is currently a lack of integrated equipment that can directly convert materials produced by pyrolysis.

[0004] Therefore, the present invention aims to provide a bio-waste pyrolysis and reduction treatment furnace to improve the deficiencies of the prior art in bio-waste treatment. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a bio-waste pyrolysis and reduction treatment furnace, which solves the problem that the current bio-waste treatment process still needs to be processed in batches through multiple devices and has a low degree of integration.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a bio-waste pyrolysis and reduction treatment furnace, comprising:

[0008] Preferably, the conveying mechanism comprises a body installed on one side above the main frame, a rotating rod is installed inside the body, a spiral blade is fixedly installed on the rotating rod, and a feeding hopper is fixedly installed below the body.

[0009] Preferably, the drying mechanism comprises a chassis and a heat pipe, two electric drums are installed inside the chassis, a hot air blower is fixedly installed on one side of the outside of the chassis, and the heat pipe is fixedly installed on the other side of the chassis.

[0010] Preferably, the crushing and pyrolysis mechanism includes a crusher fixedly connected to one side of a chassis, the crusher feed port is connected to the chassis, a vacuum cleaner is fixedly installed on one side of the crusher feed port, a dust collecting box is arranged below the crusher, the dust collecting box is fixedly installed on the top of the main frame, a pipe is arranged between the vacuum cleaner and the dust collecting box, the crusher discharge port is connected to a pyrolysis furnace, a condenser is installed above the pyrolysis furnace, and a water tank machine for injecting water and collecting steam generated during the pyrolysis process is fixedly installed on one side of the pyrolysis furnace.

[0011] Preferably, a stirring shaft is installed inside the stirring box, and a stirring blade is installed on the stirring shaft. A driver is fixedly installed on one side of the stirring box, and a first motor is installed on one side of the driver, and its output end is connected thereto.

[0012] Preferably, the premixing mechanism includes two support frames installed on the upper part of the main frame, a mixer is installed between the two support frames, a storage box is fixedly installed above the mixer, and a plurality of storage tanks are respectively arranged inside the storage box, a plurality of delivery pipes are installed between the mixer and the outlet of the storage tank, and an electric valve is installed at one end of the delivery pipes.

[0013] Preferably, the granulation mechanism comprises a pushing pipe installed on the main frame, a pressing plate is installed at one end of the pushing pipe, an electric push rod is fixedly installed on one side of the pressing plate, and a granulation disc is rotatably installed at the other end of the pushing pipe.

[0014] Preferably, a second motor is fixedly installed on one side of the pushing pipe, a cutter is installed on one end of the second motor, a conveyor belt is arranged under the granulation disc, the conveyor belt is fixedly installed on the right end of the main frame, a collecting box is installed on the rear side of the main frame, and a slide plate at an inclined angle is installed inside the collecting box.

[0015] Working principle: The present invention specifically includes the following operating steps when used:

[0016] The first step: material conveying work. Put the material to be processed into the feeding port of the conveying mechanism, and the material enters the next step with the rotation of the rotating rod and spiral blades.

[0017] Step 2: The material enters the drying mechanism for drying. In order to fully dry the material, the material enters the electric drum set in the drying mechanism. After the electric drum is continuously turned over, the moisture in the material evaporates and precipitates. Considering that it is difficult to fully evaporate the moisture only by turning and throwing, a hot air blower is set on one side of the chassis. The hot air blower transports the high-temperature pyrolysis gas generated by the pyrolysis furnace to the drying mechanism through a heat pipe. The purpose is to evenly blow the material when the electric drum is turned over, so as to better evaporate the moisture. Considering that water vapor will be generated during the drying process, the exhaust port set at the top can collect the water vapor together for purification for recycling. Considering that the drying medium will have a certain amount of residual heat, a heat pipe is set on the other side of the chassis for subsequent use.

[0018] Step 3: Send the dried material to the crushing and pyrolysis mechanism through the discharge port for processing. First, after the dried material enters the crushing device, turn on the switch and the crusher starts to run. Under the action of the crusher, some large materials can be crushed into small materials. Considering that dust may be generated during the crushing process, a vacuum cleaner is installed at the feed port; a dust box is set below the crushing pyrolysis mechanism; a conveying pipeline is set between the vacuum cleaner and the dust box to collect dust in the dust box. Secondly, the crushed material enters the pyrolysis furnace so that the material is pyrolyzed inside it. A water tank machine is set on one side of the pyrolysis furnace to cool the outside of the pyrolysis furnace. When the pyrolysis process is over, water can be injected to cool the outside of the pyrolysis furnace to extend the service life of the pyrolysis furnace. A condenser is set on the top of the pyrolysis furnace to purify the evaporated water for recycling.

[0019] Step 4: Process the biochar produced by the pyrolysis process. The biochar is fed into a mixing box and fully mixed with a mixer. A mixed substance is stored in a premixing mechanism, and a variety of fertilizer additives are stored in a storage box. An electric valve is provided at one end of the delivery pipe. The purpose is to open the corresponding electric valve according to the material needs, and the material is sent to the mixer through the delivery pipe to mix the premixed material; then, the mixed material is sent to the mixing box to be mixed with the biochar, and then the final mixing process is performed.

[0020] Step 5: Granulate the mixture of pyrolysis material and fertilizer additives. The pyrolysis material mixed with fertilizer additives is sent to the granulation mechanism, and the material is compressed into blocks by the action of the set pressing plate and electric push rod, and then granulated by the granulation disc and cutter set at one end of the granulation mechanism under the action of the second motor. The hot air inhaled by the heat pipe in the drying mechanism is used to dry the material that has just been granulated again, and the processed material is sent to the collection box through the conveyor belt set under the granulation mechanism. At this point, the operation process of the entire equipment is completed.

[0021] The present invention provides a bio-waste pyrolysis and reduction treatment furnace, which has the following beneficial effects:

[0022] 1. The present invention solves the problem that the moisture of biological waste cannot be effectively removed by setting a drying mechanism. First, the material containing a large amount of moisture is continuously turned and dried in the electric drum set in the drying mechanism. Considering that it is difficult to completely evaporate the moisture by just throwing it through the electric drum, a hot air blower is set on one side of the chassis. The purpose is to evenly blow the material with heat when the electric drum is turned over, so as to better evaporate the moisture and facilitate the subsequent crushing work.

[0023] 2. The present invention solves the problem that biological waste cannot be properly treated by setting a crushing and pyrolysis mechanism. First, the material is crushed. After the material enters the crushing device, the switch is turned on and the crusher starts to run. Under the action of the crusher, some large materials can be crushed into small materials; a dust collection box is set below the crushing and pyrolysis mechanism, and a conveying pipe is set between the dust collector and the dust collection box, in order to facilitate the collection of dust. Subsequently, the crushed material enters the pyrolysis furnace for pyrolysis treatment to achieve the reduction of biological waste.

[0024] 3. The present invention solves the problem that the pyrolyzed material cannot be effectively utilized by setting a granulation mechanism. The pyrolyzed material mixed with fertilizer additives is fed into the granulation mechanism, and the material is compressed into blocks by the action of the set pressing plate and electric push rod. The granulation process is carried out by the granulation disc and cutter set at one end of the granulation mechanism under the action of the second motor. The heat conduction pipe set on one side transports the hot air discharged from the drying mechanism to the granulation mechanism, and the material in the granulation is dried again, and the treated material is sent to the collection box through the conveyor belt set under the granulation mechanism.
