Description

Technical Field

[0001] This utility model belongs to the technical field of fracturing flowback fluid recovery devices, specifically relating to a fracturing flowback fluid recovery device. Background Technology

[0002] Fracturing flowback fluid is a liquid containing solid phase that is discharged after fracturing operations in oil and gas fields. After being discharged, fracturing flowback fluid needs to be recycled and treated. It is usually recycled and treated by a recycling device. The existing recycling device is designed for recycling fracturing flowback fluid discharged after fracturing operations in oil and gas fields, which facilitates recycling and reuse.

[0003] According to the authorized patent application No. 202320024732.9, a mobile fracturing flowback fluid recovery and treatment device is available. However, existing recovery devices do not have a mixing and stirring component inside the reagent tank when recovering fracturing flowback fluid. When a certain amount of reagent is introduced into the recovery tank from the reagent tank, the remaining reagent tends to precipitate when stored inside the reagent tank. When injecting reagent again, the bottom sediment is directly injected into the recovery collection tank, resulting in different reagent concentrations. This affects the mixing effect of the reagent injection when recovering fracturing flowback fluid. Therefore, this utility model proposes a fracturing flowback fluid recovery device. Utility Model Content

[0004] The purpose of this invention is to provide a fracturing flowback fluid recovery device to solve the problem mentioned in the background art that when the recovery device recovers fracturing flowback fluid, the inside of the reagent tank does not have a mixing and stirring component, the residual reagent is prone to precipitation when stored inside the reagent tank, and when injecting reagent again, the bottom sediment is directly injected into the recovery collection tank for treatment, resulting in different injection concentrations and reduced stirring and treatment effects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fracturing flowback fluid recovery device, comprising a fracturing flowback fluid recovery device body, the fracturing flowback fluid recovery device body including a recovery tank, a motor fixedly installed at the middle position of the top of the recovery tank, an agitator installed at the end of the motor inside the recovery tank, an inlet provided on one side of the upper surface of the recovery tank, a discharge channel provided at the bottom end of the recovery tank, a reagent tank provided on the other side of the upper surface of the recovery tank, a sealing push plate installed on the bottom side of the reagent tank via a cylinder, and the fracturing flowback fluid recovery device body also includes:

[0008] Preferably, the main stirring and mixing assembly includes a rotating shaft located at the center of the inside of the reagent tank. A sealing ring is provided between the bottom surface of the rotating shaft and the bottom of the inside of the reagent tank. Four mixers are fixedly installed on the outer surface of the rotating shaft by bolts.

[0009] Preferably, the auxiliary stirring assembly includes an auxiliary stirring rod disposed at the bottom end of the rotating shaft, and the end of the auxiliary stirring rod extends to the inner surface of the reagent tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a mixing and stirring mechanism, when there is remaining reagent inside the reagent tank, the motor drives the active disc to rotate. When the active disc rotates, it drives the driven disc and the rotating shaft to rotate via the transmission belt.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a fracturing flowback fluid recovery device, including a fracturing flowback fluid recovery device body 100, the fracturing flowback fluid recovery device body 100 including a recovery tank 101, a motor 102 fixedly installed at the middle position of the top of the recovery tank 101, a stirrer 107 installed at the end of the motor 102 inside the recovery tank 101, an inlet 105 provided on one side of the upper surface of the recovery tank 101, a discharge channel 106 provided at the bottom end of the recovery tank 101, a reagent tank 103 provided on the other side of the upper surface of the recovery tank 101, a sealing push plate 104 installed on the bottom side of the reagent tank 103 via a cylinder, and the fracturing flowback fluid recovery device body 100 also includes:

[0024] The mixing and stirring mechanism includes a main mixing component located in the middle of the inside of the reagent tank 103. An auxiliary mixing component is located at the bottom of the main mixing component inside the reagent tank 103. A drive component is located at the connection between the bottom of the main mixing component and the end surface of the motor 102. After the fracturing flowback fluid recovery device body 100 recovers the fracturing flowback fluid, the reagent tank 103 injects a certain amount of reagent into the recovery tank 101. When the reagent tank 103 stores a certain amount of reagent, the mixing and stirring mechanism mixes and stirs the reagent inside the reagent tank 103, which makes it less likely to produce sediment. When injecting reagent again, the reagent is still mixed at the original concentration.

[0025] In order to facilitate continuous mixing of the remaining medicine inside the medicine tank 103 through the main stirring and mixing assembly, and to prevent sedimentation when not in use and stored, in this embodiment, preferably, the main stirring and mixing assembly includes a rotating shaft 1031 located at the middle position inside the medicine tank 103. A sealing ring is provided between the bottom surface of the rotating shaft 1031 and the bottom of the inside of the medicine tank 103. Four mixers 1032 are fixedly installed on the outer surface of the rotating shaft 1031 by bolts. The rotating shaft 1031 can drive the mixers 1032 to rotate, and the remaining medicine stored inside the medicine tank 103 is continuously mixed by the mixers 1032, making it less likely to produce sedimentation.

[0026] In order to facilitate the rotation and mixing of the medicine at the inner edge of the medicine tank 103 when the rotating shaft 1031 rotates, in this embodiment, preferably, the auxiliary stirring assembly includes an auxiliary stirring rod 1033 disposed at the bottom end of the rotating shaft 1031, and the end of the auxiliary stirring rod 1033 extends to the inner surface of the medicine tank 103, so that the rotation of the rotating shaft 1031 can drive the auxiliary stirring rod 1033 to rotate at the inner edge of the medicine tank 103 for uniform mixing.

[0027] To facilitate the rotation and mixing of the shaft 1031 and the mixer 1032 via the drive assembly, in this embodiment, preferably, the drive assembly includes a groove 1035 formed inside the top of the recycling tank 101. A driven disk 1034 is fixedly installed inside the groove 1035 at the bottom end of the shaft 1031. An active disk 1037 is fixedly installed inside the groove 1035 at the end surface of the motor 102. A transmission belt 1036 is provided at the connection between the outer surfaces of the active disk 1037 and the driven disk 1034, which can drive the active disk 1037 to rotate. When the active disk 1037 rotates, it drives the driven disk 1034 and the shaft 1031 to rotate via the transmission belt 1036, facilitating the rotation and mixing process.

[0028] The heating mechanism includes a heating component located at the inner edge of the recovery tank 101. The outer surface of the heating component is provided with an insulation component inside the recovery tank 101. When the fracturing flowback fluid recovery device body 100 adds chemicals for mixing after recovering the fracturing flowback fluid, the heating mechanism heats and mixes the fracturing flowback fluid recovered inside the recovery tank 101, thereby improving the reaction rate of the fracturing flowback fluid recovery device body 100 after fully mixing the recovered fracturing flowback fluid.

[0029] In order to facilitate the heating and thorough mixing of the fracturing flowback fluid recovered inside the recovery tank 101 by means of a heating component, in this embodiment, preferably, the heating component includes a mounting groove 1012 formed at the inner edge of the recovery tank 101. An electric heating wire 1013 is wound on the inner surface of the mounting groove 1012. The top end of the electric heating wire 1013 extends to the outer surface of the recovery tank 101 and is provided with a plug wire 1011. When the recovery tank 101 is injected with chemicals and mixed with the fracturing flowback fluid, the electric heating wire 1013 can be energized and heated through the plug wire 1011, thereby heating and thoroughly mixing the fracturing flowback fluid inside the recovery tank 101.

[0030] In order to facilitate effective heating and thorough stirring in winter through the insulation component, in this embodiment, preferably, the insulation component includes an insulation groove 1014 formed on the outer surface of the mounting groove 1012 and located inside the recovery tank 101. The insulation groove 1014 is provided with an insulation board 1015. When the tank is heated inside the recovery tank 101 in winter, the insulation groove 1014 isolates the cold air from the outside, and the insulation board 1015 provides heat protection during internal heating.

[0031] The working principle and usage process of this utility model are as follows: When using this fracturing flowback fluid recovery device, the inlet 105 can be connected to the external fracturing flowback fluid discharge pipe. Therefore, when recovering fracturing flowback fluid, it directly enters the recovery tank 101 through the inlet 105. After the chemical tank 103 is filled with chemicals, the cylinder drives the sealing push plate 104 to open appropriately to inject chemicals into the tank. After the chemicals are injected into the recovery tank 101, the motor 102 drives the stirrer 107 to rotate. When the stirrer 107 rotates, it effectively mixes the fracturing flowback fluid and chemicals. After mixing, it can be easily discharged again through the discharge channel 106 for reuse.

[0032] Then, when the fracturing flowback fluid recovery device 100 recovers the fracturing flowback fluid into the recovery tank 101 and mixes it through the agitator 107, the plug wire 1011 is simultaneously connected to an external power source to energize the heating wire 1013. When energized, the heating wire 1013 heats the inner surface of the recovery tank 101. Prolonged heating facilitates uniform heating and stirring of the fracturing flowback fluid inside the agitator 107. In winter, the heating wire 1013 is isolated inside the isolation tank 1014. During heating, the insulation board 1015 keeps the heat and isolates the cold air from the outside, making it easier to heat effectively during stirring and facilitate thorough mixing. The mixing effect is more obvious, improving the rate of thorough mixing reaction of the fracturing flowback fluid recovery device 100 after recovery, and effectively recovering the fluid.

[0033] Finally, when the fracturing flowback fluid recovery device 100 recovers the fracturing flowback fluid and injects chemicals, and when a certain amount of chemicals are injected, there are still chemicals remaining inside the chemical tank 103, the motor 102 can drive the stirrer 107 to mix inside the recovery tank 101. The motor 102 drives the active disc 1037 to rotate. When the active disc 1037 rotates, it drives the driven disc 1034 and the rotating shaft 1031 to rotate through the transmission belt 1036. When the rotating shaft 1031 rotates, it drives the mixer 1032 to mix inside the chemical tank 103. At the same time, the auxiliary stirring rod 1033 rotates to mix the inner surface of the chemical tank 103. This makes it easier to continuously mix the remaining chemicals inside the chemical tank 103, preventing sedimentation. When injecting chemicals again, the chemicals are still mixed at the original concentration, improving the chemical mixing effect of the fracturing flowback fluid recovery device 100 in recovering fracturing flowback fluid.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
