Technical Field
The utility model relates to an environmental protection technology field specifically is a feeding system of oiliness mud pyrolysis.
Background
The oily sludge is from the crude oil exploitation process, is recorded as a dangerous waste by the name of national hazardous waste, and has the main particularity of inflammability and explosiveness, high water content and oil content. At present, the main stream technology for treating the oily sludge is pyrolysis, and a rotary pyrolysis furnace is used for indirectly heating the oily sludge.
Due to the water content and oil content of the oil-containing sludge and the complex change of material characteristics under various working conditions, for example, the water content can be changed from extremely easy flowing of 85% to a drier state of below 50%, the adaptability of the material blanking and conveying mechanism is seriously challenged, and the main equipment is stopped due to the fact that the material cannot be conveyed and blanked normally. Generally, the means suitable for transporting dilute materials are not suitable for transporting dry materials and vice versa. For example, screw pumps, screw conveying and other modes have strict material characteristic ranges and cannot adapt to frequent changes of dry materials and thin materials; some designs are equipped with two feeding and conveying modes at the same time, and are complex and clumsy.
In addition, due to the inflammable and explosive properties of the oily sludge, strict requirements are imposed on the sealing performance of the blanking mechanism. Furthermore, the connection of the rotary drum of the rotary pyrolysis furnace to the charging device must also take into account dynamic sealing.
To the above current situation, the utility model provides a feeding system of oiliness mud pyrolysis.

An object of the utility model is to overcome above-mentioned weak point to a feed system of oiliness mud pyrolysis has avoided traditional pump sending, screw transport in-process material and the jam between the machinery, adapts to various material characteristic changes, and equipment is simple, safe, reliable.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a feeding system of oiliness mud pyrolysis, includes bucket elevator, oiliness mud hopper, two flap valves, drum, rotary seal, rotary drum, characterized by: the discharge port of the bucket elevator is connected with the feed inlet of the oily sludge hopper, the lower part of the oily sludge hopper is connected with the double-flap valve, the discharge end of the double-flap valve is connected with the feed inlet of the vertical pipe, the discharge port of the vertical pipe is connected with the feed inlet of the inner extension pipe, one end of the cylinder is connected with the vertical pipe and surrounds the inner extension pipe, and the other end of the cylinder is connected with the rotary roller of the pyrolysis main body through rotary sealing.
Further, the space between the cylinder and the inner extension pipe is a cavity.
Furthermore, a supporting seat is arranged at the bottom of the cylinder.
The utility model has the advantages that: the utility model discloses avoid traditional pump sending, jam between screw feed process material and the machinery, adapted to various material characteristic changes, equipment is simple, safe, reliable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: 1. the device comprises a bucket elevator, a sludge hopper 2, an oil-containing sludge hopper 3, a double-flap valve 4, a vertical pipe 5, an inner extending pipe 6, a cylinder 7, a supporting seat 8, a rotary seal 9, a rotary roller 10 and a pyrolysis main body.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1: the utility model relates to a feeding system of oiliness mud pyrolysis, including bucket elevator 1, oiliness mud hopper 2, two flap valves 3, drum 6, rotary seal 8, rotary drum 9, characterized by: the feed inlet of oily sludge hopper 2 is connected to the discharge gate of bucket elevator 1, the sub-unit connection double flap valve 3 of oily sludge hopper 2, the feed inlet of perpendicular pipe 4 is connected to the discharge end of double flap valve 3, and the feed inlet of interior pipe 5 is connected to the discharge gate of perpendicular pipe 4, and perpendicular pipe 4 is connected to the one end of drum 6 and the interior pipe 5 that stretches is surrounded, and the other end of drum 6 passes through rotary seal 8 and connects the rotary drum 9 of pyrolysis main part 10.
The space between the cylinder 6 and the inner extension tube 5 is a cavity.
The bottom of the cylinder 6 is provided with a supporting seat 7.
The bucket elevator 1 is conventional equipment, and as the materials are conveyed bucket by bucket, the problem of blockage caused by extrusion of the materials in a pumping or spiral conveying mode is solved.
Oily sludge hopper 2 and two flap valves 3 be conventional device, two flap valves 3 are located oily sludge hopper 2 below, play the effect of unloading and isolated air, are convenient for keep the oxygen deficiency atmosphere of follow-up main part pyrolysis process, prevent that oil gas from revealing the explosion.
The vertical pipe 4 is positioned below the double-flap valve 3, and a certain height is suggested for a descending channel of the material, so that the material falls with certain kinetic energy.
The inner extension pipe 5 is connected with the vertical pipe 4 and is bent downwards to form an angle of about 135 degrees. The larger the angle of bending downwards is, the smoother the material falls by gravity, and the specific size is determined according to the actual condition.
One end of the cylinder 6 is connected with the vertical pipe 4 and surrounds the inner extension pipe 5, so that on one hand, the sealing of the blanking mechanism is kept, on the other hand, the cylinder 6 also needs to meet the requirement of connecting a body rotary roller 9, and enough space is reserved for installing the rotary seal 8 and keeping a round shape so as to be convenient for arranging the rotary seal 8. The space between the cylinder 6 and the inner extension tube 5 is a cavity.
The utility model discloses a working process: oily sludge enters an oily sludge hopper 2 from a raw material yard through a bucket elevator 1, the two turning valves 3 are controlled to perform blanking operation, and then the material falls by gravity and enters a rotary drum 9 of a pyrolysis main body 10 through a vertical pipe 4 and an inner extension pipe 5 to complete the feeding process of the material. The cylinder 6 connects the vertical pipe 4 and the rotary drum 9 surrounding the inner pipe 5, and is connected to the pyrolysis body 10 by a rotary seal 8.
