Description

Technical Field

[0001] This invention relates to the field of rock asphalt production and processing technology, specifically to a dehydration processing device for rock asphalt. Background Technology

[0002] Rock asphalt is an asphalt-like substance formed from petroleum through millions of years of sedimentation and changes, under the combined effects of heat, pressure, oxidation, catalysts, and bacteria. In order to remove the water contained in rock asphalt during production and processing, rock asphalt dehydration processing equipment is required.

[0003] Existing Chinese patent CN116769501B, published on October 27, 2023, discloses a dehydration processing device for rock asphalt, relating to the field of rock asphalt dehydration technology. The device includes a shell, with a support leg fixedly connected to the bottom end of the shell. A dehydration tank is installed inside the shell, and a discharge pipe rotatably connected to the bottom end of the dehydration tank extends to the outside of the shell. A rotating ring rotatably connected to the shell and rotatably connected to the dehydration tank is also present. This rock asphalt dehydration processing device and its processing method utilize an air inlet pipe, a connecting sleeve, and a connecting pipe to deliver high-temperature steam to the gap between the shell and the dehydration tank, and to deliver high-temperature steam to the connecting pipe extending into the dehydration tank.

[0004] However, the above-mentioned device uses steam to heat the rock asphalt inside the tank during dehydration, and uses internal and external heating for dehydration. When the rock asphalt contains too much water, the internal and external heating method takes a long time to dehydrate, and the rock asphalt cannot move effectively during dehydration. During dehydration, most of the material piles up together, making the overall dehydration not very efficient.

[0005] Therefore, it is necessary to provide a dehydration processing device for rock bitumen to solve the above-mentioned technical problems. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Please see Figures 1-7 The present invention provides a technical solution: a dehydration processing device for rock asphalt, comprising a spiral extrusion dehydration mechanism, a dehydration hot gas input mechanism, a dehydration hot gas output mechanism, a dehydration collection mechanism, a first stage conveying dehydration mechanism, and a second stage conveying dehydration mechanism 2.

[0040] The screw extrusion dewatering mechanism receives rock asphalt for extrusion dewatering and conveying. During conveying, the screw extrusion dewatering mechanism achieves material dewatering through the synergistic effect of screw extrusion and gap filtration. A dewatering hot air input mechanism is installed on the inner right side of the screw extrusion dewatering mechanism, which delivers hot air into the internal rods of the mechanism, allowing for heating and dehumidification during the screw extrusion dewatering process. This improves the overall dewatering efficiency of the rock asphalt. A dewatering hot air output mechanism is installed on the inner left side of the screw extrusion dewatering mechanism, receiving the hot air discharged from the mechanism. A dewatering collection mechanism is fixed to the lower end of the screw extrusion dewatering mechanism, collecting the hot air discharged from the mechanism. The dewatering and dehydration process involves collecting water and evaporated gas from the dewatering system. This system is connected to an external wastewater treatment device, which purifies the wastewater and prevents environmental pollution. A first-stage conveying dewatering mechanism is installed on the lower left side of the screw extrusion dewatering mechanism.

Hot gas inside the hot gas connecting pipe 11 can be transported into the first wrapping sleeve 13. The first wrapping sleeve 13 has a cross-shaped positioning air delivery groove 14 inside, which can transport hot gas to the cross-shaped positioning air delivery groove 14. In the cross-shaped positioning air supply groove 14, the first wrapping sleeve 13 is sleeved on the right end protrusion of the conical conveying shaft 43 through the cross-shaped positioning air supply groove 14. The gas inside the cross-shaped positioning air supply groove 14 can be input into the inside through the slot 41 of the conical conveying shaft 43. The conical conveying shaft 43 is filled with hot air, which can be used for heating and dehydration during spiral dehydration feeding. The left end of the hollow square cover 12 is fixed to the outer shell 4 of the extrusion dehydrator and can be placed stably. The right end of the hollow square cover 12 is equipped with a rotary motor 1 by screws, so that the rotary motor 1 is easy to install and remove.

[0045] The exhaust pipe 61 and the hot gas connection pipe 11 are connected to an external circulating heating device, so that heating can be circulated.

The dewatering hot air output mechanism receives the hot air discharged from the screw extrusion dewatering mechanism. The dewatering collection mechanism receives and processes the moisture and evaporated gas after dewatering by the screw extrusion dewatering mechanism.
