Description

Automatic inputting device for regenerating system of waste plastics pyrolyzing oil}

The present invention relates to an automatic input device of a waste synthetic resin pyrolysis oil regeneration system, and more particularly, to remove waste synthetic resins introduced into a pyrolysis furnace (= regeneration chamber) from a waste synthetic resin pyrolysis oil regeneration system, which can be automatically introduced. It is to provide an automatic feeding device.

Generally, a waste synthetic resin pyrolysis oil regeneration system capable of obtaining pyrolysis oil by condensing gas vaporized by thermal decomposition of waste synthetic resin has been well known.

In the waste synthetic resin pyrolysis oil regeneration system, the raw material, that is, the waste synthetic resin is added manually, and the operation of the pyrolysis furnace is stopped every time the raw material is injected, and a predetermined time has elapsed before the raw material is input. Of course, there is a problem that the work efficiency is extremely deteriorated, and the development of an automatic feeding device capable of automatically injecting materials while continuously operating the device was a major task of the industry.

Accordingly, the present invention is to provide an automatic feeding device that can eliminate the problems of material input of the existing waste synthetic resin pyrolysis oil regeneration system as described above,

The present invention has been completed in view of the technical problem of the present invention, in particular, by providing an automatic input device capable of automatically inserting a material after removing air during operation of a pyrolysis furnace.

1 and 2 are a front view and a plan view showing the overall layout of the waste synthetic resin pyrolysis oil regeneration system in which the automatic feeding device 1 provided by the present invention is installed, and FIGS. 3, 4, and 5 are the automatic feeding device of the present invention ( As a plan view, a side cross-sectional view and a front view, etc., which are extracted from 1), the present invention will be described in detail below.

The present invention is to install a first injection pipe (5) on the input hopper (4) in order to automatically put the waste synthetic resin onto the regeneration chamber (3) installed on the combustion chamber (2) of the waste synthetic resin pyrolysis oil regeneration system Opening and closing of the knife gate valve 7 and the shutter 8 which are opened and closed on the first and second input pipes 5 and 6 by installing a second input pipe 6 perpendicular to the first input pipe 5. By operation, the outside air is not introduced into the regeneration chamber 3, but only the waste synthetic resin can be introduced automatically,

To this end, a pusher 11 connected to the rod 10 of the cylinder 9 is installed at the rear side of the first input pipe 5, and the pusher 11 has several air as shown in more detail in FIG. 7. When the discharge pipe 11a is installed and the valve 11c made of rubber material elastically installed at the rear end thereof by the spring 11b is installed, when the pusher 11 pushes the waste synthetic resin, the air inside the pressure is higher than a certain pressure. When it is automatically discharged through the air discharge pipe (11a),

On the side of the first input pipe (5), a so-called knife gate valve (7) is installed up and down, and the waste synthetic resin introduced onto the first input pipe (5) on the input hopper (4) is pushed into the pusher (11). When the knife gate valve (7) is opened after compression transfer to the side of the first injection pipe (5) by the opening so that the drop transport on the second injection pipe (6) connected in a vertical direction with the first injection pipe (5) do.

The lower end of the second input pipe 6 is connected to the regeneration chamber 3, and at the lower end thereof, a shutter 8 that is opened and closed in the lateral direction is installed, and the waste synthetic resin injected onto the second input pipe 6 is regenerated chamber. (3) It will control whether or not it is put into the phase.

That is, the shutter 8 is installed at the lower end of the second feeding pipe 6, and the shutter 8 is composed of left and right split shutters 8a and 8b, and a cylinder on the frame 13 on which the guide 12 is installed. It is to be connected to the rod 15 of 14) to open and close the slide operation.

In the drawings, reference numeral 16 denotes a condenser, 17 a heat exchanger, 18 a multi-cyclone, 19 a washing tower, and 20 a stack.

The automatic input device for waste synthetic resin pyrolysis oil regeneration system (1) of the present invention, which can be configured as described above, is installed in an existing waste synthetic resin pyrolysis oil regeneration system to pyrolyze waste synthetic resin to obtain pyrolysis oil. As it can be put automatically, its action is described in more detail below.

When the waste synthetic resin introduced through the feed hopper 4 falls to the first feed pipe 5, the pusher 11 connected to the rod 10 moves forward by the expansion operation of the cylinder 9 to remove the waste synthetic resin. 1 is compressed by pushing onto the knife gate valve (7) installed at the end of the input pipe (5), at which time the waste synthetic resin is pushed by the pusher 11, the air remaining inside the air discharge pipe formed in the pusher ( When the pressure is higher than a predetermined pressure through 11a), the valve 11c elastically installed on the spring 11b is opened to be discharged to the outside, and only the waste synthetic resin from which air is discharged is collected at the end of the first input pipe 5. When the knife gate valve 7 is opened, the waste synthetic resin is transferred and dropped onto the second input pipe 6.

When the material is dropped into the second input pipe 6, the knife gate valve 7 is closed, the cylinder 9 is contracted and the pusher 11 is reversed, and the second input pipe 6 is closed. The divided shutters 8a and 8b provided at the lower side are opened, i.e., the cylinder 14 is contracted and the left and right divided shutters 8a and 8b connected to the rod 15 end thereof are opened. The material dropped on the two injection pipes 6 automatically completes the drop injection onto the lower regeneration chamber 3.

When the dropping of the material is completed, the divided shutters 8a and 8b are guided and closed by the guide 12 by the extension operation of the cylinder 14, and the material is repeated to the regeneration chamber 3 by repeating the same procedure as before. It is to be continuously repeated, the input waste synthetic resin is heated by the high temperature heat heated in the combustion chamber (2) to obtain the pyrolysis oil after cooling through the drying process, and the air in the combustion chamber (2) through the purifying means Clean air is emitted to the atmosphere.

As described in detail above, the automatic input device 1 for waste synthetic resin pyrolysis oil regeneration system provided by the present invention may include first and second input pipes 5 and 5 which are introduced into the regeneration chamber 3 depending on existing manual work. By 6, the pusher 11, the knife gate valve 7 and the shutter 8 can be intermittently inserted while the air is removed, thereby reducing the manpower and continuously operating the device. The expected effect is a great invention, such as to maximize the.
