Technical Field
[0001] This utility model relates to the field of sludge treatment technology, specifically a fracturing flowback fluid sludge treatment device. Background Technology
[0002] Fracturing flowback fluid sludge is a waste product from natural gas and oil extraction. It is characterized by high viscosity and stability, containing a large amount of suspended solids and complex components, making it difficult to treat. Currently, natural air drying and chemical treatment are the main methods, but these methods are time-consuming and cause secondary pollution. In recent years, the emergence of new technologies such as MVR forced circulation evaporation, electrocoagulation, and ozone catalytic oxidation can effectively treat petroleum-based substances, suspended solids, and recalcitrant organic matter, enabling wastewater reuse and achieving compliant discharge. In particular, MVR evaporation technology uses thermal energy to evaporate moisture, reducing wastewater discharge and achieving resource utilization. It is speculated that fracturing flowback fluid sludge treatment systems may include steps such as degrading macromolecular organic matter and dewatering.
[0003] Publication number CN205773882U discloses a high-efficiency fracturing flowback fluid treatment system, comprising a filtration tank, an oil separator, a first intermediate water tank, a first reactor, a second reactor, a third reactor, a magnetic separation device, a second intermediate water tank, an aeration device, a coarse filter tank, a fine filter tank, a collection tank, a sludge drying tank, and a chemical dosing tank. The filtration tank of this invention features a grid structure with a higher center and lower sides to prevent insoluble matter from clogging the grid, facilitating the handling of separated insoluble matter and improving the practicality of the filtration tank. Simultaneously, the introduction of carriers through multiple reactors enhances the flocculation and binding capacity of suspended pollutants in the water, improving the flocculation effect. Furthermore, the two-stage filtration system further improves the treatment efficiency of the fracturing flowback fluid.
[0004] The above technology utilizes components such as a filtration tank, an oil separator, an intermediate water tank, a reactor, a reactor, a reactor, a magnetic separation device, etc., to treat the stains in the water. However, the magnetic separation process requires a long time.
[0005] Therefore, in view of this, we have studied and improved the existing shortcomings and proposed a fracturing flowback fluid sludge treatment device. Utility Model Content
[0006] The purpose of this invention is to provide a fracturing flowback fluid sludge treatment device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a fracturing flowback sludge treatment device, comprising: a reaction tank, a conveying pipe provided on one side of the reaction tank, a water pump provided on one side of the conveying pipe, a first mixing tank provided on one side inside the reaction tank, filter plates placed at equal intervals in the middle of the first mixing tank, an electric telescopic rod body extending through the back of the reaction tank, a push plate provided at the front end of the electric telescopic rod body, a water guide groove provided at the lower end of the front of the first mixing tank, and a pressing plate provided at the upper end of the water guide groove;
[0008] A second mixing tank is provided on the other side of the reaction tank, and an auxiliary structure is provided at the top of the second mixing tank.
[0009] Furthermore, the filter plate is fixedly connected to the first mixing tank to prevent the filter plate from tilting due to excessive impact force from the sludge liquid.
[0010] Furthermore, the multiple equal-area spaces formed between the filter plate and the first mixing tank facilitate the pusher plate to move back and forth in the space between the first mixing tank and the filter plate.
[0011] Furthermore, the side angle of the push plate is an obtuse angle, and the lateral width of the push plate is equal to the width of the water guide channel, so that the push plate can push the sludge liquid into the water guide channel.
[0012] Furthermore, the auxiliary structure includes a motor assembly, a sliding plate, a rotating rod, water holes, and a mud scoop. The top of the second mixing tank is provided with a sliding plate, the top of the sliding plate is provided with a motor assembly, the top of the motor assembly is provided with a rotating rod, and the bottom of the rotating rod is provided with a mud scoop in a ring. Multiple water holes are opened on the inner side of the mud scoop. The water holes are fixedly connected to the rotating rod to facilitate the rotation of the water holes.
[0013] Furthermore, the skateboard is slidably connected to the edge of the top of the second mixing pool, making it easy for the user to move the skateboard to the top of the second mixing pool.
[0014] Furthermore, the height of the rotating rod is equal to the depth of the second mixing tank, so that the rotating rod can make the depth of the mud scoop equal to the internal depth of the second mixing tank.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In this utility model, sludge liquid is introduced into the first mixing tank by a water pump and a conveying pipe. The filter plate can block the sludge impurities in the liquid on the surface of the filter plate. At the same time, the electric telescopic rod body drives the push plate to move laterally in the isolation space formed by the filter plate and the first mixing tank. The push plate discharges the water liquid in the space between the filter plate and the first mixing tank from the water guide channel. The pressing plate prevents the water liquid from being discharged too much. This facilitates the separation of liquid water and solid impurities in the sludge.
[0017] 2. This utility model uses a sliding plate at the top of the second mixing tank to move the motor assembly at the top of the sliding plate, which drives the rotating rod to rotate. The rotating rod drives the sludge scoop to rotate, and the water hole on the inside of the sludge scoop drains out a small amount of liquid contained in the sludge inside the scoop. In this way, before the sludge liquid is introduced into the first mixing tank, the sludge liquid pre-stored in the second mixing tank will be stirred by the sludge scoop, and the scoop will first store some of the impurities in the sludge liquid.

[0025] 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.
[0026] like Figures 1-6 As shown, a fracturing flowback sludge treatment device includes: a reaction tank 1, a conveying pipe 8 on one side of the reaction tank 1, a water pump 9 on one side of the conveying pipe 8, a first mixing tank 2 inside the reaction tank 1 on one side, filter plates 5 evenly placed in the middle of the first mixing tank 2, an electric telescopic rod body 3 penetrating through the back of the reaction tank 1, a push plate 4 at the front end of the electric telescopic rod body 3, a water guide trough 11 at the lower end of the front of the first mixing tank 2, and a pressing plate 10 at the upper end of the water guide trough 11.
[0027] A second mixing tank 6 is provided on the other side of the interior of the reaction tank 1, and an auxiliary structure 7 is provided at the top of the second mixing tank 6.
[0028] The rest, since the filter plate 5 blocks the impurities contained in the sludge liquid inside the first mixing tank 2 on the surface of the filter plate 5, the electric telescopic rod body 3 drives the push plate 4 to move inside the first mixing tank 2. The push plate 4 pushes the sludge liquid contained in the isolation space formed between the first mixing tank 2 and the filter plate 5. At the same time, the water guide trough 11 discharges the liquid contained in the sludge, and the pressing plate 10 presses the volume of liquid discharged by the water guide trough 11. The designer can set multiple filter plates 5 of different specifications, and arrange the filter plates 5 of different specifications from left to right, from large to small. In this way, the volume of liquid discharged by the pressing plate 10 will decrease from large to small.
[0029] This has resulted in the following effects and novel technologies:
[0030] The design of this fracturing flowback fluid sludge treatment device incorporates several novel technologies to achieve highly efficient solid-liquid separation. By placing filter plates 5 at equal intervals inside the first mixing tank 2, impurities in the sludge liquid are effectively blocked, improving treatment efficiency and effectiveness. An electric telescopic rod body 3 drives the pusher plate 4 to move inside the first mixing tank 2, achieving dynamic cleaning of the pusher plate 4 and periodically removing impurities from the surface of the filter plate 5 to prevent clogging and maintain filtration efficiency. Liquid volume control, through the design of the water guide trough 11 and the pressing plate 10, allows for precise control of the discharged liquid volume. Filter plates 5 of different specifications are arranged from large to small, gradually decreasing in size. With a small liquid volume, it achieves fine processing; structural stability is ensured by the fixed connection between the filter plate 5 and the first mixing tank 2, preventing the filter plate 5 from tilting and ensuring stable operation; the equal area space design facilitates the pusher plate 4 to move back and forth, ensuring uniform liquid distribution and improving efficiency; the side angle of the pusher plate 4 is obtuse, and its width matches the water guide channel 11, ensuring smooth liquid introduction and reducing leakage or waste; the auxiliary structure 7 at the top of the second mixing tank 6 enhances processing capacity and flexibility. Through its innovative design, this device achieves efficient and stable treatment of fracturing return sludge, promotes resource utilization, and reduces environmental pollution.
[0031] like Figures 1-6As shown, a fracturing flowback sludge treatment device includes an auxiliary structure 7 comprising a motor assembly 71, a sliding plate 72, a rotating rod 73, water holes 74, and a sludge scoop 75. A sliding plate 72 is located at the top of the second mixing tank 6, and a motor assembly 71 is located at the top of the sliding plate 72. A rotating rod 73 is located at the top of the motor assembly 71, and a sludge scoop 75 is annularly arranged at the bottom end of the rotating rod 73. Multiple water holes 74 are provided on the inner side of the sludge scoop 75, and the water holes 74 are fixedly connected to the rotating rod 73.
[0032] As the slide plate 72 moves at the top of the second mixing tank 6, the motor assembly 71 at the top of the slide plate 72 drives the rotating rod 73 to rotate, and the rotating rod 73 drives the sludge scoop 75 to rotate. When the sludge scoop 75 rotates, it continuously stirs the sludge inside the second mixing tank 6. The water hole 74 can drain the liquid contained in the sludge inside the sludge scoop 75. The designer can increase the internal area of the sludge scoop 75 to increase the usable area of the sludge scoop 75.
[0033] This has resulted in the following effects and novel technologies:
[0034] The auxiliary structure 7 of this fracturing flowback fluid sludge treatment device incorporates several novel technologies, achieving dynamic stirring and separation. The motor assembly 71 at the top of the slide plate 72 drives the rotating rod 73 to rotate, which in turn rotates the sludge scoop 75, dynamically stirring the sludge inside the second mixing tank 6, facilitating better separation of solids and liquids. Simultaneously, multiple water holes 74 on the inner side of the sludge scoop 75 enable efficient liquid discharge, further concentrating the sludge and improving treatment efficiency. Enlarging the internal area of the sludge scoop 75 increases the treatment area and enhances the sludge treatment capacity. The pretreatment sludge step ensures that the sludge liquid inside the second mixing tank 6 is stirred and impurities are stored before the sludge liquid is introduced into the first mixing tank 2, preparing for subsequent treatment. The sliding connection design of the slide plate 72 provides flexible operability, facilitating adjustment of the stirring position and intensity. The height of the rotating rod 73 matches the depth of the second mixing tank 6, ensuring uniform and thorough stirring. The innovative design of the auxiliary structure 7 not only improves the efficiency and effectiveness of fracturing flowback fluid sludge treatment but also enhances operational flexibility and the adaptability of the device.
[0035] Working Principle: When using this fracturing flowback fluid sludge treatment device, the water pump 9, together with the delivery pipe 8, first introduces the external sludge liquid into the interior of the reaction tank 1. The second mixing tank 6 comes into contact with the sludge liquid for the first time. The user moves the slide plate 72, and the motor assembly 71 at the top of the slide plate 72 drives the rotating rod 73 to rotate. The rotating rod 73 drives the mud scoop 75 to stir the sludge liquid inside the second mixing tank 6. While rotating, the mud scoop 75 continuously scoops up the sludge liquid, and at the same time, the water hole 74 can discharge the sludge liquid. At this time, the sludge liquid processed by the mud scoop 75 enters the interior of the first mixing tank 2. The filter plate 5 filters the sludge liquid, and the solid impurities in the sludge liquid are blocked by the filter plate 5. The electric telescopic rod body 3 drives the push plate 4 to move in the space between the first mixing tank 2 and the filter plate 5. The push plate 4 pushes the water contained in the sludge out of the water guide trough 11, and the pressing plate 10 suppresses the amount of water discharged from the water guide trough 11. This is the working principle of the fracturing flowback fluid sludge treatment device.

Many modifications and variations will be apparent to those skilled in the art.
