Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.

As shown in fig. 1 to 3, the discharging device for disposing the oil-containing rock debris comprises a conveyor 1 and a sealing mechanism; one end of the conveyor 1 is a discharge hole; the sealing mechanism comprises a material plate 2 and a bracket 3; the material plate 2 is used for sealing the discharge hole; one end of the bracket 3 is arranged outside the discharge hole, and the other end of the bracket is provided with an elastic part 4; and one end of the elastic piece 4, which is far away from the discharge hole, is connected with the material plate 2.

In this embodiment, the conveyor 1 is a tubular screw conveyor 1, which drives the material by means of an internal screw. In the present embodiment, in order to reduce the assembly volume of the bracket 3 as much as possible without affecting the movement of the flitch 2, the bracket 3 is designed to include two parts, namely a first bracket body 31 and a second bracket body 32, wherein the first bracket body 31 has an L-shaped cross section, and the second bracket body 32 has an I-shaped cross section; one end of the first support 3 is arranged on the outer shell of the discharge hole, and the other end of the first support 3 is connected with one end of the second support 3, so that the second support 3 extends towards the central axis of the discharge hole; the elastic part 4 is arranged at one end of the second support 3 far away from the first support 3, and under the elastic action, when the discharging device is not used, the material plate 2 is tightly attached to the discharging port, so that the conveyor 1 is sealed.

From this, after starting discharging device, the material is through conveyer 1's transportation, the initial stage, the elasticity of elastic component 4 can't be overcome to the effort that it gave, thereby make the material pile up in discharge gate department, after piling up through certain period of time, the density increase of material, if conveyer 1 maintains the transportation ability, then improve power take off, at this in-process, conveyer 1 can overcome the effort that elastic component 4 gave flitch 2 gradually to the thrust that the material provided, when two kinds of above-mentioned forces are balanced, can realize the incessant unloading of fine and close material, thereby form sealedly in discharge gate department, ensure that oil water mixed steam can't contact with the outside air.

In order to better use the embodiment, the material sealing device further comprises a sealing pipe 5, wherein the sealing pipe 5 is of a horn-shaped structure, one end with a small caliber is communicated with the material outlet, and one end with a large caliber is close to the material plate 2; the flitch 2 is used for sealing one end with a large caliber of the sealing pipe 5.

Because the tubular screw conveyer 1 is generally a straight pipe, in the conveying process of oil-based rock debris dry slag, when the material bolt reaches a certain density, the friction force between the material and the inner wall of the shell of the conveyer 1 is continuously increased in the process of forward propulsion under extrusion force, and a great propulsion resistance can be formed, so that the motor load of the conveyer 1 greatly rises before abnormal discharging to cause accident shutdown.

Thus, the sealing tube 5 with the horn-shaped structure can well solve the problem. The material bolt constantly advances under screw thrust, and the material bolt volume of unit length constantly increases at the removal in-process, and the constantly increasing of material bolt volume leads to closely knit degree constantly to reduce to avoided the frictional force between material bolt and the shell inner wall to increase by a wide margin and arouse to shut down, at this moment, the thrust that conveyer 1 gave does not influence the fine and close degree of material bolt, ensured discharging device's sealing performance.

In the actual use process, the ideal state in the use process rarely appears, and because before the oil-based rock debris material enters the discharging device, the oil-based rock debris material is limited by the properties of the raw material, can not be screened and classified, and can only be subjected to simple processing work such as crushing, iron removal and the like, the quantity and the state of fine powder, particles and blocky materials in the treated dry material can not be estimated. It should be noted here that the subsequent equipment should perform material drying and cooling, which is generally implemented by negative pressure air draft.

From this, if the material that gets into conveyer 1 contains when more cubic material, easily causes the material that the stuff bolt formed to seal and destroys, under no special measure, in case the material that the stuff bolt formed seals and takes place to destroy, negative pressure convulsions directly take away high temperature oil water mixed steam and fine powder material in the conveyer 1, because of the stuff bolt clearance that no fine powder material filled the cubic material formation in the material this moment, hardly form effectual material gas isolation again to arouse system danger.
