Abstract
The utility model relates to a waste plastics cracking oil burning apparatus, which comprises a pre-melting apparatus and a cracking pot. An electric screwed propelling mechanism is arranged in the pre-melting apparatus and the pre-melting apparatus is connected with a material feeding port of the cracking pot, and an end port of the pre-melting apparatus is provided with a non-return door. A cracking heating zone is additionally arranged outside the cracking pot and the bottom of the cracking pot is in a medially convex shape. The pot bottom is made of three layers of different materials, wherein, an upper and a lower layers are iron plate layers, and the middle layer is a metallic plumbum layer. A stirring jaw of a stirrer is designed into an arch which is matched with the shape of the pot bottom. The utility model has the advantages of more than ten times cracking work efficiency improvement, cracking time shortening, energy saving and a plurality of times prolonging of the service life of the pot bottom.
Description
The utility model relates to a kind of device that utilizes waste plastic to produce fuel oil, is meant waste plastic cracking oil burning installation in the said process especially.
When utilizing waste plastic to produce fuel oil, waste plastic need refine back gas through series reaction such as quick cracking and form fuel oil through condensation again, the defective of common employed cracking still because of existing on its structure causes energy consumption height, the lysis efficiency of cracking still low, cracking still is shorter service life.
The purpose of this utility model is to provide a kind of novel waste plastic cracking oil burning installation, and this cracker has pre-fusing device, makes waste plastic process preheating earlier before entering cracking still, to improve lysis efficiency.
Another purpose of the present utility model is to provide a kind of novel waste plastic cracking oil burning installation, is middle convex at the bottom of the still of this cracker, to increase the material heating surface area, to cut down the consumption of energy.
A purpose more of the present utility model is to provide a kind of novel waste plastic cracking oil burning installation, is made by three layers of different metal at the bottom of the still of this cracker, and its heat resistance is strengthened greatly, with the life-span at the bottom of the prolongation still.
Above-mentioned purpose of the present utility model can be achieved through the following technical solutions.
A kind of waste plastic cracking oil burning installation includes cracking still and pre-fusing device, and an electric screw propulsive mechanism is arranged in the described pre-fusing device, and this pre-fusing device links to each other with the charging aperture of cracking still, and at its port one non-return flap is set.In the cracking still outside, other is provided with the cracking thermal treatment zone, and this thermal treatment zone is made by temperature-resistant material.Be convex-shaped at the bottom of its still of cracking still in the utility model, and made by three layers of different materials at the bottom of the still, wherein two-layer up and down is the iron plate layer, and the centre is the lead metal layer.Need stir in the cracking reaction process, the stirring pawl of agitator is designed to the arch that is complementary with the still Bottom Shape.
Compare with traditional cracking still, the utility model has been owing to adopted particular structure, thereby has tangible advantage: 1. enter the stokehold earlier through the pre-fusing device of this equipment at waste plastic, shortened the cracking time, make cracking reaction more abundant, improve tens times of cracking operating efficiencies; 2. be designed to camber at the bottom of the still of cracking still,, make cracking reaction more abundant, further reach the purpose that shortens the cracking time, and saved the energy to increase heating surface area; 3. adopted different metal materials at the bottom of the still of cracking still, reduced, thereby prolonged life-span at the bottom of the still greatly the loss at the bottom of the still.
Also in conjunction with the accompanying drawings design feature of the present utility model and use effect are described further below by embodiment.
Fig. 1 is the utility model waste plastic cracking oil burning installation structural representation.
The number in the figure explanation:
The pre-fusing device of 1-
11-electric screw propulsive mechanism 12-non-return flap
13-agitator at the bottom of the 2-cracking still 21-cracking still still
The power set of 3-agitator
The 4-cracking thermal treatment zone
See also shown in Figure 1, the utility model waste plastic cracking oil burning installation includes pre-fusing device 1 and cracking still 2 two parts, in the wherein pre-fusing device 1 an electric screw propulsive mechanism 11 is arranged, this pre-fusing device 1 links to each other with the charging aperture of cracking still 2, and is provided with a non-return flap 12 at its port.Waste plastic enters in the pre-fusing device through feeding port, and this device pushes cracking still 2 by the electric screw propeller, will pass through low-temperature space and high-temperature region in the process that pushes, and advances cracking still then.The principle that produces low-temperature space and high-temperature region is the position of heating on the one hand, the 2nd, and screw coaxial pitch difference, fltting speed difference, corresponding heated time length difference.The fritting plastics are pushed in the cracking still through non-return flap 12, and the setting and the use of pre-fusing device have improved more than tens times the operating efficiency of cracking still.The fritting plastics heat at the bottom of entering into still, and the cracking heating-up temperature is about 400 ℃, use temperature-resistant material to make the cracking thermal treatment zone 4 around the cracking still, form independent single unit system.21 are designed to convex-shaped at the bottom of cracking still 2 its stills in the utility model, increasing heating surface area, and are made by three layers of different materials at the bottom of the still, promptly upper and lower two-layer be the iron plate layer, the centre is the lead metal layer.It has been proven in practice that want at the bottom of its service life is than conventional still long number doubly more than.In the cracking reaction process, need stir, the stirring pawl of agitator 13 is designed to the arch that is complementary with the still Bottom Shape, simultaneously the power that provided of the power set 3 of agitator with need firmly change corresponding variation at the bottom of the still, it installs and adopts hydraulic motor, and adopts the quantitative oil mass of oil circuit, slows down and make pressure rising in the system in the stressed back of motor, thereby increase Torque Performance of Hydraulic Motor, by stirring, make plastics reach cracking, and the while deslagging.
Utilize principle of the present utility model, also this waste plastic cracking oil burning installation can be made into refinery device in small-sized early stage separately, make this device civil nature, individual family also can be produced in earlier stage, the product of producing carries out the cracking of secondary refinery by the purchase of refinery factory again, make the plastics pollution engineering common peopleization, and can therefrom obtain corresponding economic benefit.
