Description

Technical Field

[0001] The utility model relates to the technical field related to oil sludge treatment, and in particular to a device for treating oil sludge with a high water content. Background Art

[0002] Oil sludge is the sludge generated during crude oil extraction, storage, gathering, processing, and crude oil production liquid treatment. Some of it can be recycled, so it needs to be recycled.

[0003] The existing announcement number is: CN217103500U, a high-water content sludge treatment device, which injects carbon dioxide into the sludge treatment tank through an air pump, and at the same time increases the air pressure in the sludge treatment tank, so that a large amount of carbon dioxide is dissolved in the high-water content sludge. After standing for a period of time until the carbon dioxide is fully dissolved, the air vent is opened, and the motor is turned on at the same time. The scraper slides left and right to scrape the sludge particles brought up by the carbon dioxide to the other side of the partition.

[0004] The above-mentioned problem exists. Although the oil sludge can be separated from the solid and liquid by allowing the oil sludge particles driven by carbon dioxide to float up through the method of adding gas and pressurizing, the height of the partition is fixed. If too much sludge is added at one time, the water level may be too high to overflow to the left side of the partition after the gas and pressurization treatment. If too little sludge is added, the water level may be too low and the scraper cannot reach the floating oil sludge particles. The staff needs to control the amount of sludge added, which is relatively troublesome for the staff to operate. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1, with reference to Figures 1 to 5A high-water-content sludge processing device includes a box body 1, an air pump 2 is installed at one end of the box body 1, and the model of the air pump 2 can be selected according to actual conditions. A first motor 3 is installed at one end of the box body 1, and the model of the first motor 3 can be selected according to actual conditions. The output end of the first motor 3 is connected to a round rod 4, and the round rod 4 is rotatably connected to the box body 1. Two sets of groove wheels 5 are connected to the round rod 4, and the two sets of groove wheels 5 are wound and connected with a rope body 6. The first motor 3 drives the groove wheel 5 to rotate through the round rod 4 to retract and release the rope body 6. A mesh plate 7 is placed in the box body 1, and the two sets of rope bodies 6 are connected to the mesh plate 7. A baffle 12 is provided in the box body 1, and a feed port 15 is connected to the box body 1. A plate body 16 is rotatably connected to the box body 1 through a rotating shaft. The plate body 16 fits the feed port 15, and a first bolt 17 is threadedly connected to the plate body 16. The other end of the first bolt 17 is threadedly connected to the feed port 15, and two groups of valve bodies 21 are connected to the box body 1. The valve body 21 located above the box body 1 is an exhaust valve, and the valve body 21 located below the box body 1 is a drain valve. Unscrew the first bolt 17, rotate the plate 16 to open the feed port 15, put the sludge into the box body 1, start the air pump 2 to inject carbon dioxide into the box body 1, and at the same time increase the air pressure in the box body 1 to make a large amount of carbon dioxide dissolve in the high-water content sludge. Let it stand for a period of time until the carbon dioxide is fully dissolved, which will separate the solid and liquid of the sludge. Open the exhaust valve in the valve body 21 to discharge the gas, start the first motor 3 to drive the mesh plate 7 to move upward, and the sludge particles above the water surface are accumulated on the mesh plate 7. The liquid is filtered to the bottom of the box body 1, avoiding the need for staff to control the amount of input every time, and the operation is relatively convenient.

[0025] In this embodiment, a second motor 10 is installed at one end of the box body 1. The model of the second motor 10 can be selected according to actual conditions. The output end of the second motor 10 is connected to a threaded rod 11. The threaded rod 11 is rotatably connected to the box body 1. The threaded rod 11 is threadedly connected to the baffle 12. The second motor 10 drives the baffle 12 to move horizontally through the threaded rod 11. One end of the baffle 12 is connected to a bellows 13. The threaded rod 11 is placed inside the bellows 13 to prevent sludge particles from adhering to the threads of the threaded rod 11 and affecting the movement of the baffle 12 driven by the threaded rod 11. One end of the bellows 13 is connected to a connecting rod 14. The other end of the connecting rod 14 is connected to the inner wall of the box body 1, ensuring that the bellows 13 can contract as the baffle 12 moves. A door 19 is hinged at one end of the box body 1. A rubber gasket 20 is adhered between the door 19 and the box body 1. The rubber gasket 20 acts as a seal to prevent gas from escaping from the joint between the box body 1 and the door 19 when gas is added and pressurized into the box body 1, thereby affecting the effect of gas addition and pressurization. A second bolt 22 is threadedly connected to one end of the box body 1. The other end of the second bolt 22 is threadedly connected to the door 19. The second bolt 22 secures the door 19 to prevent it from being pushed open during gas addition and pressurization. A collection box is placed at one end of the box body 1. Slots 9 are formed at one end and the other end of the box body 1. Sliders 8 are connected to one end and the other end of the mesh plate 7. The slides 8 are slidably connected to the slots 9, and the slots 9 serve as guides for the mesh plate 7. Two sets of slideways are connected to the mesh plate 7 to prevent sludge particles from accumulating on both sides of the rope body 6, which would prevent the baffle 12 from pushing the sludge particles out. A rubber ring 18 is attached to the joint between feed port 15 and plate 16 to prevent gas from escaping from feed port 15 during pressurization of chamber 1, potentially affecting the effectiveness of the pressurization process. Two rods are connected to chamber 1, each slidably connected to baffle 12, which guides the baffle 12. The length of baffle 12 is shorter than the distance between the two ropes 6, preventing damage from collision.

[0026] The working principle of this embodiment is as follows: when in use, the first bolt 17 is unscrewed, the plate 16 is rotated to open the feed port 15, the oil sludge is put into the box body 1, the feed port 15 is closed, the air pump 2 is started to inject carbon dioxide into the box body 1, and the air pressure in the box body 1 is increased at the same time, so that a large amount of carbon dioxide is dissolved in the high-water content oil sludge. After standing for a period of time, the carbon dioxide is fully dissolved, which will separate the solid and liquid of the oil sludge. The exhaust valves in the two sets of valve bodies 21 are opened, and the oil sludge particles will float up. The first motor 3 is started to drive the mesh plate 7 to move upward, and the floating oil sludge particles are accumulated on the surface of the mesh plate 7. The oil-water mixture is filtered to the bottom of the box body 1 below the mesh plate 7. The door 19 is opened, and after the mesh plate 7 moves to the baffle 12, the second motor 10 is started and the first motor 3 is closed, which drives the baffle 12 to move horizontally and push the oil sludge particles on the mesh plate 7 to the collection box placed on one side of the box body 1 to complete the collection of the oil sludge particles. The drain valves in the two sets of valve bodies 21 are opened to discharge and collect the oil-water mixture. The overall oil sludge treatment process is relatively simple and convenient for staff to operate.
