Description

Technical Field

[0001] This patent relates to the field of asphalt wastewater treatment, specifically an asphalt wastewater recycling treatment pool. Background Art

[0002] Asphalt wastewater refers to the wastewater containing asphalt produced during the process of petroleum refining when crude oil is distilled under normal and vacuum conditions or other means to extract asphalt products.

[0003] When treating asphalt wastewater, flocculants need to be added to the treatment pool to cause the asphalt particles in the wastewater to coagulate and grow, and then separate them by gravity. However, since the asphalt itself has high viscosity, it is easy to adhere to the bottom of the treatment pool and solidify after sedimentation, which increases the difficulty of cleaning. If not handled in time, scale will form in the facility. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this patent is to provide an asphalt wastewater recycling treatment pool.

[0005] The technical solution adopted by this patent to solve its technical problem is: an asphalt wastewater circulation treatment tank, including a sedimentation tank, an oil-water separator and a secondary sedimentation tank, the sedimentation tank, the oil-water separator and the secondary sedimentation tank are connected in sequence, and a liquid inlet pipe is inserted and installed in the sedimentation tank, and the liquid inlet pipe discharges the asphalt wastewater into the sedimentation tank;

[0006] The left and right sides of the side wall of the sedimentation tank are both equipped with electric control push rods, which are electrically connected to an external power supply. The side wall of the sedimentation tank is equipped with an electric slide rail, which is electrically connected to an external power supply. The output ends of the two electric control push rods are respectively installed on both sides of the electric slide rail.

[0007] Slide blocks are slidably mounted on both left and right sides of the electric slide rail, a connecting frame is mounted on the lower wall of the slide block, an inclined plate is mounted on the side wall of the connecting frame, and the inclined plate is fitted with the inner wall of the sedimentation tank.

[0008] Furthermore, a fixed plate is installed on the inner wall of the sedimentation tank, a water injection cavity is opened inside the fixed plate, a connecting pipe is inserted into the side wall of the sedimentation tank, the connecting pipe passes through the sedimentation tank and is connected with the side wall of the fixed plate and the water injection cavity, and the inclined plate is fitted with the upper wall of the fixed plate.

[0009] Furthermore, the sedimentation tank, the oil-water separator and the secondary sedimentation tank are all connected through pipelines, and gate valves are installed in the pipelines.

[0010] Furthermore, one end of a support rod is installed on the side wall of the sedimentation tank, and a fixing ring is installed on the other end of the support rod, and the fixing ring is sleeved on the outside of the liquid inlet pipe.

[0011] Furthermore, a drain pipe is inserted into the side wall of the secondary sedimentation tank, and a drain valve is installed on the side wall of the drain pipe.

[0012] Furthermore, an oil drain pipe is installed on the lower wall of the oil-water separator.

[0013] The beneficial effects of this patent are:

[0014] The device can control the two sliders to move toward the middle through an electric slide rail, so that during the movement, the asphalt attached to the fixed plate can be scraped off through the inclined plate on the connecting frame. At the same time, the device also provides a water injection cavity in the fixed plate, so that when there is solidified asphalt on the fixed plate, hot water can be injected into the water injection cavity through the connecting pipe to heat the fixed plate, so that the solidified asphalt on the top can be melted, making it easier for the inclined plate to scrape it off.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0019] See also Figure 1 , Figure 2 This is a schematic diagram of the structure of the patent, an asphalt wastewater circulation treatment tank, including a sedimentation tank 1, an oil-water separator 2 and a secondary sedimentation tank 3, the sedimentation tank 1, the oil-water separator 2 and the secondary sedimentation tank 3 are connected in sequence, and a liquid inlet pipe 4 is inserted and installed in the sedimentation tank 1, and the liquid inlet pipe 4 discharges the asphalt wastewater into the sedimentation tank 1;

[0020] After the asphalt wastewater is discharged into the sedimentation tank 1 through the liquid inlet pipe 4, it will be initially precipitated, and then the flocculant will be evenly sprinkled into the sedimentation tank 1 to promote the aggregation and growth of asphalt particles in the wastewater, and separate from the water by gravity. The separated asphalt will fall onto the top of the fixed plate 10. After the wastewater has been flocculated and settled, it will enter the oil-water separator 2 through the pipeline 13, and then rotate at a high speed in the oil-water separator 2 to separate the oil and water in the wastewater. The separated water will enter the secondary sedimentation tank 3 through the pipeline 13 for secondary sedimentation, and can be discharged for recycling or directly discharged after the sedimentation is completed.

[0021] The grease separated by the oil-water separator 2 will be discharged through the oil drain pipe 19;

[0022] Electric control push rods 5 are installed on the left and right sides of the side wall of the sedimentation tank 1. The electric control push rods 5 are electrically connected to the external power supply. The side wall of the sedimentation tank 1 is installed with electric slide rails 6. The electric slide rails 6 are electrically connected to the external power supply. The output ends of the two electric control push rods 5 are respectively installed on both sides of the electric slide rails 6.

[0023] When the asphalt left in the sedimentation tank 1 needs to be cleaned, the slider 7 can be controlled by the electric slide rail 6 to move to the middle position. During the movement, the inclined plate 9 on the connecting frame 8 will scrape the asphalt on the fixed plate 10. When the two inclined plates are in contact with each other, the electric control push rod 5 can be controlled to push the electric slide rail 6 upward, so that the conical bucket formed by the two inclined plates 9 can take the asphalt out of the sedimentation tank 1.

[0024] This structure does not require workers to go down into the sedimentation tank 1, making it convenient to clean the sedimentation tank 1;

[0025] Slide blocks 7 are slidably installed on both left and right sides of the electric slide rail 6 , a connecting frame 8 is installed on the lower wall of the sliding block 7 , an inclined plate 9 is installed on the side wall of the connecting frame 8 , and the inclined plate 9 is in contact with the inner wall of the sedimentation tank 1 .

[0026] A fixing plate 10 is installed on the inner wall of the sedimentation tank 1, and a water injection cavity 11 is opened inside the fixing plate 10. A connecting pipe 12 is inserted and installed on the side wall of the sedimentation tank 1. The connecting pipe 12 penetrates the sedimentation tank 1 and is connected to the side wall of the fixing plate 10 and the water injection cavity 11. The inclined plate 9 is in contact with the upper wall of the fixing plate 10.

[0027] In order to solve the problem that the solidified asphalt is not easy to clean, the device is provided with a fixed plate 10 in its sedimentation tank 1. By injecting hot water into the water injection cavity 11 in the fixed plate 10, the temperature of the fixed plate 10 is increased, so that the asphalt solidified on the fixed plate 10 is melted, which is convenient for the inclined plate 9 to scrape it off.

[0028] The sedimentation tank 1, the oil-water separator 2 and the secondary sedimentation tank 3 are all connected through a pipeline 13, and a gate valve 14 is installed in the pipeline 13;

[0029] The oil-water separator 2 proposed in this article is an industrial cyclone oil-water separator, which is a prior art. Its principle is that wastewater enters the separator from the inlet on the cyclone chamber, that is, the pipe 13 connected to the sedimentation tank 1, forming a spiral flow, and the fluid is accelerated through the two-stage contraction of the contraction chamber and the tail cone, and a stable centrifugal field is formed inside the separator. The heavy phase water in the waste liquid is thrown to the inner wall of the cyclone under the action of strong centrifugal force and is discharged from the bottom flow port in a spiral state, while the light phase oil gathers toward the center of the separator to form an oil core, which is discharged from the overflow port to achieve oil-water separation.

[0030] One end of a support rod 15 is installed on the side wall of the sedimentation tank 1 , and a fixing ring 16 is installed on the other end of the support rod 15 . The fixing ring 16 is sleeved on the outer side of the liquid inlet pipe 4 .

[0031] A drainage pipe 17 is inserted into the side wall of the secondary sedimentation tank 3 , and a drainage valve 18 is installed on the side wall of the drainage pipe 17 .

[0032] An oil drain pipe 19 is installed on the side wall of the oil-water separator 2 .

[0033] When the present invention is working, after the asphalt wastewater is discharged into the sedimentation tank 1 through the liquid inlet pipe 4, it will be initially precipitated, and then the flocculant will be evenly sprinkled into the sedimentation tank 1 to promote the aggregation and growth of asphalt particles in the wastewater, and separate from the water by gravity. The separated asphalt will fall onto the top of the fixed plate 10. After the wastewater has been flocculated and settled, it will enter the oil-water separator 2 through the pipeline 13, and then rotate at a high speed in the oil-water separator 2 to separate the oil and water in the wastewater. The separated water will enter the secondary sedimentation tank 3 through the pipeline 13 for secondary sedimentation, and can be discharged for recycling or directly discharged after the sedimentation is completed.

[0034] When the asphalt in the sedimentation tank 1 needs to be cleaned, the slider 7 is moved to the middle position by the electric slide rail 6. During the movement, the inclined plate 9 on the connecting frame 8 will scrape the asphalt on the fixed plate 10. When the two inclined plates are in contact with each other, the electric control push rod 5 can be controlled to push out the electric slide rail 6 upward, so that the conical bucket formed by the two inclined plates 9 can bring the asphalt out of the sedimentation tank 1.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
