Description

Technical Field

[0001] The utility model relates to the technical field of equipment for oil sludge treatment, in particular to a feeding device for oil sludge treatment. Background Art

[0002] Oil sludge is an oily solid waste generated during the oilfield drilling, transportation, refining and oily wastewater treatment. Oilfield sludge contains a large amount of foul odor, pathogens, parasites, and harmful chemical heavy metals such as copper, zinc, chromium, and mercury that exceed the standard. If it is not effectively and promptly treated, it will cause serious harm and corrosion to the surrounding crop soil cultivation, water bodies, air, and ecological environment. When treating oil sludge, pyrolysis is often used. When using pyrolysis to treat oil sludge, the oily sludge needs to go through a feeding system, a cracking system, an oil separation cooling system, a non-condensable combustible gas purification system, a flue gas purification system, a discharging system, and a circulating water cooling system to complete pyrolysis. In the actual production process of oil sludge treatment, a screw feeder is usually used as a feeding device to transport the oil sludge to the cracking system for processing.

[0003] Chinese patent document CN210945491U discloses an automatic feeding device for oil sludge processing, in which the discharge pipe of the conveyor body is inserted into the rotary furnace feed pipe by sliding cooperation and the positioning through hole is aligned coaxially with the limiting through hole, and then the discharge pipe is detachably fixed in the rotary furnace feed pipe by inserting the pull rod through the positioning through hole into the limiting through hole, thereby preventing the discharge pipe and the rotary furnace feed pipe from being misaligned during the feeding process, and at the same time, the disassembly and assembly of the discharge pipe and the rotary furnace feed pipe are fast and easy to operate, so that the conveyor body and the rotary furnace feed pipe can be quickly separated at the end of feeding to store them separately.

[0004] The existing technology has the following problems:

[0005] Traditional screw conveyors cannot separate the oil and solid waste in the sludge and directly feed the materials, which not only wastes oil and gas resources, but also causes the sludge to adhere to the inner wall of the feed barrel. Long-term retention of the sludge will corrode the feed barrel and emit a heavy odor. When the screw conveyor and the rotary furnace need to be cleaned, the discharge pipe end of the screw conveyor and the feed pipe end of the rotary furnace need to be disassembled to facilitate the cleaning of the residual materials in the discharge pipe and the feed pipe. When the feed pipe of the rotary furnace is disassembled, the residual materials at the discharge pipe end and inside the feed pipe are easy to fall and scatter on the ground, resulting in material waste.

DETAILED DESCRIPTION

A vortex vane 82 is fixedly installed on the outer surface of the rotating shaft 85. Three connecting rings 83 are fixedly installed on the outer surface of the rotating shaft 85 at the position of the inner cavity of the feeding barrel 3. A scraper 84 is fixedly installed at one end of the three connecting rings 83 away from the rotating shaft 85. The storage component 9 includes a connecting pipe 91. The upper end of the connecting pipe 91 is fixedly installed with the lower part of the left side of the outer surface of the feeding barrel 3. An oil storage tank 92 is fixedly installed at the lower end of the connecting pipe 91, and the lower surface of the oil storage tank 92 is fixedly installed with the left side of the upper surface of the cross plate 2. A discharge pipe 93 is fixedly installed on the left side of the oil storage tank 92. The material receiving component 7 includes a material receiving drawer 71 and two sliders 72. The outer walls of the two sliders 72 are slidably connected with the inner walls of the two slide grooves 13 respectively. The material receiving drawer 71 is arranged below the feeding barrel 3.

[0027] The oil sludge is added into the feeding barrel 3 through the feeding pipe 10, and the motor 81 is energized. The motor 81 drives the rotating shaft 85 and the vortex vane 82 to rotate to feed the oil sludge, and the oil sludge is transported to the feeding pipe 6 of the rotary furnace, so that the oil sludge is transported to the next processing equipment for processing. The moisture and oil in the oil sludge enter the oil storage tank 92 through the connecting pipe 91 and are stored. When the rotary furnace feeding pipe 6 needs to be removed, the handle on the material receiving drawer 71 is pulled to move the material receiving drawer 71 to the bottom of the discharge pipe 5 and the rotary furnace feeding pipe 6, and then it is disassembled. The residual materials in the discharge pipe 5 and the rotary furnace feeding pipe 6 can be collected through the material receiving drawer 71 to prevent the materials from falling and scattering on the ground, thereby avoiding the waste of materials. It is easy to use, and the end cover 11 and the rotary furnace feeding pipe 6 are convenient to disassemble through the flange 4 and bolts, so that the feeding barrel 3, the vortex vane 82 and the discharge pipe 5 can be cleaned.

[0028] like Figure 3 , Figure 4 As shown, the vortex vane 82 is a composite vortex vane, which comprises, from left to right, a single helix portion 1 821, a double helix portion 822, and a single helix portion 2 823, and the outer diameter of the single helix portion 1 821 is greater than the outer diameter of the single helix portion 2 823. The single helix portion 2 823 is located in the inner cavity of the discharge pipe 5, and the outer diameter of the single helix portion 2 823 gradually decreases from left to right.

[0029] The single spiral part 821 is used for adding materials, which makes the feeding smoother. The double spiral part 822 is used for discharging materials. While discharging materials, it cooperates with the cavity on the right side of the feeding cylinder 3 to squeeze and compact the sludge. The single spiral part 823 transports the sludge in the discharge pipe 5 to the rotary furnace feed pipe 6, and the oil and solid waste in the sludge are separated, reducing the waste of oil and gas resources.

[0030] like Figure 3 , Figure 4 As shown, the scraper 84 is in an arc shape, and the outer diameter of the scraper 84 is equal to the outer diameter of the cavity of the feeding barrel 3.

[0031] The rotation of the rotating shaft 85 drives the connecting ring 83 and the scraper 84 to rotate, and the sludge adhered to the inner wall of the feeding barrel 3 is scraped off to avoid the sludge accumulation for too long or the emission of a heavy odor. There is no need to frequently clean the device, and it can work uninterruptedly for a long time.

[0032] like Figure 1-Figure 5 As shown, a through hole is opened at the lower part of the inner side of the feeding cylinder 3, and the connecting pipe 91 is connected to the through hole, and a filter screen 12 is fixedly installed on the inner wall of the through hole.

[0033] The oil and solid waste in the oil sludge are separated by the filter screen 12, so that the oil sludge can be compacted more easily, the waste of oil and gas resources is reduced, and the subsequent treatment is more convenient.

[0034] like Figure 1 , Figure 3 As shown, the cavity of the feeding cylinder 3 is a truncated cone structure, and its outer diameter gradually decreases from left to right, and the lower part of the cavity of the oil storage tank 92 is inclined.

[0035] The double helix part 822 is used for discharging materials, and at the same time cooperates with the cavity on the right side of the feeding cylinder 3 to squeeze and compact the sludge. The oil storage tank 92 is used to store filtered water and oil. The lower part of the cavity of the oil storage tank 92 is inclined to facilitate the outflow of liquid.

[0036] like Figure 5-Figure 7 As shown, the front and rear positions of the left side of the lower surface of the material receiving drawer 71 are fixedly mounted to the upper surfaces of the two sliding blocks 72 respectively, and the sliding groove 13 and the sliding block 72 are both in an I-shape.

[0037] By pulling the handle on the material receiving drawer 71 and moving the material receiving drawer 71 to the bottom of the discharge pipe 5 and the rotary furnace feed pipe 6, the residual materials in the discharge pipe 5 and the rotary furnace feed pipe 6 can be collected to prevent the materials from falling and scattering on the ground, thereby avoiding waste of materials and facilitating use.

[0038] The working principle of the present invention is as follows: the oil sludge is added into the feeding barrel 3 through the feeding pipe 10, and the motor 81 is energized. The motor 81 drives the rotating shaft 85 and the vortex vane 82 to rotate to feed the oil sludge. The vortex vane 82 is a three-stage composite vortex vane. The single spiral part 821 is used for feeding, and the feeding is smoother. The double spiral part 822 is used for discharging. While discharging, the oil sludge is squeezed and compacted in cooperation with the cavity on the right side of the feeding barrel 3. The single spiral part 823 transports the oil sludge in the discharging pipe 5 to the feeding pipe 6 of the rotary furnace, thereby transporting the oil sludge to the next processing equipment for processing. The rotation of the rotating shaft 85 drives the connecting ring 83 and the scraper 84 to rotate, and scrapes off the oil sludge adhered to the inner wall of the feeding barrel 3 to avoid the oil sludge accumulating for too long or emitting a heavy odor. The oil sludge is compacted. During the process, the cavity of the feed barrel 3 is set to a truncated cone structure, so that water and oil can slide down along the inner wall to the left side, pass through the filter screen 12 and flow into the through hole, and then enter the oil storage tank 92 through the connecting pipe 91 to be stored. When the rotary furnace feed pipe 6 needs to be removed, pull the handle on the material receiving drawer 71, move the material receiving drawer 71 to the bottom of the discharge pipe 5 and the rotary furnace feed pipe 6, and then disassemble it. The material receiving drawer 71 can be used to collect the residual material in the discharge pipe 5 and the rotary furnace feed pipe 6 to prevent the material from falling and scattering on the ground, thereby avoiding waste of material. It is easy to use, and the end cover 11 and the rotary furnace feed pipe 6 are convenient to disassemble through the flange 4 and bolts, so that the feed barrel 3, the vortex vane 82, and the discharge pipe 5 can be cleaned.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
