Description

Technical Field

[0001] The utility model relates to the technical field of waste environmental protection treatment, in particular to a waste oil sludge treatment device for water coal slurry gasification. Background Technique

[0002] The water coal slurry gasification technology is a coal gasification technology developed on the basis of heavy oil gasification and belongs to the pressurized entrained flow gasification technology. In this technology, solid coal is mixed with limestone and water to form water coal slurry, which is then sent into the gasification furnace through a coal slurry pump and undergoes a series of gasification reactions with gasifying agents such as oxygen in the furnace, finally generating raw synthesis gas mainly composed of CO and H2. An oil sludge centrifuge is a three-phase separation device specifically used to separate oil, water, and solid components in an oil-containing sludge mixture in the industrial and environmental fields. It can efficiently separate oil, water, and solid impurities in the oil sludge, thereby realizing the recovery of oil, reducing pollutant emissions, and reducing waste treatment costs.

[0003] During the use of the oil sludge centrifuge, waste oil sludge is input into the centrifuge through a feed pipe. After the material is centrifuged by the rotation of the drum in cooperation with the screw pusher rod, the solid phase, water phase, and oil phase are discharged from different outlets. Since a large force is generated during the process of centrifugally throwing out the solid phase, the thrown solid phase adheres to the protective cover above the drum. When the solid phase of some oil sludge falls following the gravity, the continuous rotational centrifugal force of the drum will throw the oil sludge onto the protective cover again, causing the solid phase to accumulate on the inner wall of the protective cover. When the accumulation is excessive, the operation of the drum is blocked. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a waste oil sludge treatment device for water coal slurry gasification to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0032] Please refer to Figures 1-4, A waste oil sludge treatment device for water coal slurry gasification, comprising: a main body 1, a drum 2, and a sliding rod 304. An outer protective cover 101 is hinged above the main body 1 to prevent the three phases from being thrown to other non-collection areas, and a through hole 102 is formed through one side of the outer protective cover 101; the drum 2 is rotatably connected to the main body 1, and a pushing rod 202 is arranged in the inner cavity of the drum 2. The centrifugal force of the drum 2 and the spiral pushing rod 202 cooperate to centrifuge the materials; the outer surface of the sliding rod 304 slides in the through hole 102, and a scraping strip 306 that fits the inner wall of the outer protective cover 101 is fixedly connected to the end of the sliding rod 304. One side of the scraping strip 306 that fits the inner wall of the outer protective cover 101 is an inclined surface, which is convenient for scraping the solid phase.

[0033] Among them, the sliding rod 304 is divided into two sections, namely a circular section and a square section. The circular section of the sliding rod 304 is located in the through hole 102. By setting the circular section of the sliding rod 304, the smooth running of the sliding rod 304 in the inner cavity of the outer protective cover 101 is ensured. While reciprocatingly scraping the inner wall, the solid phase on the outer surface of the circular section of the sliding rod 304 is scraped off through the through hole 102 adapted to the outer protective cover 101, avoiding the accumulation of the solid phase during waste oil sludge treatment.

[0034] Furthermore, a drive shaft 201 is arranged at one end of the drum 2 away from the feed pipe 203, and an external drive is connected to the drive shaft 201. An inclined disk 3 is fixedly connected to the outer surface of the drive shaft 201. While driving the drum 2 to rotate through the drive shaft 201, the inclined disk 3 is caused to rotate, which is driven by the mechanical self-power, reducing the consumption of external energy.

[0035] It should be noted that a solid phase outlet 206 is arranged on one side of the drum 2 close to the sliding rod 304, and a liquid outlet 205 is arranged on the side of the drum 2 away from the solid phase outlet 206. The end of the pushing rod 202 is fixedly connected to the main body 1, and a feed pipe 203 penetrates through the inner cavity of the pushing rod 202. A discharge port 204 is arranged on one side of the end of the pushing rod 202 where the feed pipe 203 is located. The feed rod feeds the waste oil sludge to the discharge port 204, and with the centrifugal force of the drum 2, the three phases are thrown to different outlets for discharging.

[0036] Furthermore, the body 1 is provided with a support seat 302, and a connecting hole 303 is provided through the support seat 302, and the connecting hole 303 is square. The inner wall of the connecting hole 303 is slidably connected with the square section of the sliding rod 304, and a group of fixing rods 305 are provided on the sliding rod 304. It should be supplemented that the fixing rods 305 are respectively located on both sides of the tilting plate 3, and grooves 301 are provided on both sides of the tilting plate 3. One end of the fixing rod 305 away from the sliding rod 304 slides in the groove 301. The square section provided on the sliding rod 304 prevents the sliding rod 304 from rotating along the axis during the sliding process, thereby avoiding the displacement of the fixing rod 305, so that the bottom of the fixing rod 305 is always located in the slide groove, and the sliding rod 304 reciprocates left and right under the promotion of the tilting plate 3.

[0037] Through all the above embodiments, the working principle of the utility model is:

[0038] When in use, first start the external control of the drive shaft 201, then open the feed pipe 203 so that the waste sludge enters the inner cavity of the push rod 202 from the feed pipe 203 and is discharged from the discharge port 204. At this time, the centrifugal force of the rotation of the drum 2 prompts the oil phase and the liquid phase to be discharged from the liquid outlet 205, and the push rod 202 pushes the solid phase to the solid phase outlet 206. At the same time, the rotation of the inclined disk 3 prompts it to continuously squeeze or push the fixed rod 305, so that the sliding rod 304 slides back and forth in the connection hole 303 and the through hole 102 opened by the support seat 302 and the outer shield 101, and prompts the scraper 306 to scrape off the solid phase attachments to avoid solid phase accumulation. The long-term attachment of solid phase materials will hinder the flow and further treatment of waste sludge. The scraper 306 can remove these attachments in time, keep the processing channel or the inner wall of the container clean, ensure the smooth flow of waste sludge and the continuity of the processing process, thereby improving the overall processing efficiency.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
