Description

Technical Field

[0001] This utility model belongs to the field of coagulation and hardening technology, and in particular relates to a stirring device for a coagulation and hardening reaction tank. Background Technology

[0002] In the full-scale treatment process of fracturing flowback fluid in the oil and gas extraction industry, the coagulation and hardening reaction tank is the core equipment in the pretreatment stage to reduce the hardness of the flowback fluid and remove scale substances such as calcium and magnesium ions. Its treatment effect directly affects the operational stability and service life of the subsequent MVR evaporation system. The liquid being treated has the characteristics of high hardness and complex types of scale substances. If scale adheres to the inner wall of the reaction tank during the coagulation and hardening process, it will reduce the heat transfer efficiency of the wall surface, affect the reaction effect of the reagents, and even cause blockage of subsequent pipelines and equipment. Therefore, a stirring device with a scraper structure is required to achieve the synergistic effect of tank wall cleaning and material mixing during the reaction process.

[0003] However, existing stirring devices are not convenient for compensating for wear between the scraper and the inner wall of the reactor during use. As the coagulation and hardening operation continues, the scraper blades wear down, creating gaps between the scraper and the inner wall. Impurities adhere to these gaps and form scale, which not only reduces the heat transfer efficiency of the inner wall and prolongs the coagulation and hardening cycle, but also increases the difficulty of subsequent equipment cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a stirring device for a coagulation and hardening reaction tank. By setting up a self-compensating cleaning part, it solves the problem that existing stirring devices for coagulation and hardening reaction tanks are not easy to compensate for the wear between the scraper and the inner wall of the reactor during use. As the coagulation and hardening operation continues, the scraper blades wear down and it is difficult to compensate for the wear, resulting in gaps between the scraper and the inner wall. High-hardness water is easy to adhere to the gaps and form scale, which not only reduces the heat transfer efficiency of the inner wall and prolongs the coagulation and hardening cycle, but also increases the difficulty of subsequent equipment cleaning.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a stirring device for a coagulation and hardening reaction tank, comprising a reaction vessel, and further comprising: a sludge discharge section disposed on the reaction vessel; a self-compensating cleaning section disposed inside the reaction vessel; a stirring section installed inside the reaction vessel; the self-compensating cleaning section comprising several elastic components disposed inside the reaction vessel; a support component disposed inside the reaction vessel; and several cleaning components disposed inside the reaction vessel. Each elastic component includes a sliding rod disposed inside the reaction vessel, with a limit block fixedly connected to the outer wall of the sliding rod, and a spring sleeved on the outer wall of the sliding rod. There are sixteen elastic components and eight cleaning components, and the elastic components provide power for compensation.

[0006] Furthermore, the sludge discharge section includes a steam pipe connected to the right side of the reactor, a feed pipe connected to the right side of the reactor, and a sludge discharge component on the left side of the reactor.

A protective shell is fixedly connected to the left side of the reactor. A pipe cover is provided on the inner wall of the sludge discharge pipe. A pull rod is fixedly connected to the left side of the pipe cover. The left side of the pull rod slides out of the reactor.

[0007] Furthermore, the support assembly includes a support frame rotatably connected to the inner wall of the reactor. Several rectangular plates are arranged inside the reactor. A sliding rod is fixedly connected to a rectangular plate on its side near the rectangular plate, and slides through the support frame on its side away from the rectangular plate. A spring is fixedly connected to a rectangular plate on its side near the rectangular plate, and fixedly connected to the support frame on its side away from the rectangular plate. Four rectangular plates are provided, and each rectangular plate has four elastic components and two cleaning components. The support assembly provides support for the cleaning components.

[0008] Furthermore, the cleaning assembly includes a U-shaped block fixedly connected to the side of the rectangular plate away from the slide bar, a scraper is installed on the U-shaped block, and a stirring plate is fixedly connected to the side of the rectangular plate away from the rectangular plate; the side of the scraper away from the rectangular plate is in contact with the inner wall of the reactor, and the cleaning assembly is used to remove impurities on the inner wall of the reactor.

[0009] Furthermore, the stirring unit includes a power assembly disposed on the inner wall of the reactor; and a plurality of stirring assemblies arranged in a circumferential array inside the reactor.

[0010] Furthermore, the power assembly includes a motor fixedly connected to the right side of the reactor. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The left side of the rotating shaft extends into the reactor. The rotating shaft passes through the support frame and is fixedly connected thereto. The rotating shaft is rotatably connected to the reactor, and the power assembly is used to drive the stirring assembly.

[0011] Furthermore, the stirring assembly includes several connecting rods fixedly connected to the outer wall of the rotating shaft, and a spiral blade is fixedly connected to the side of the several connecting rods away from the rotating shaft. The stirring assembly is used to accelerate the coagulation and hardening process.

[0012] This utility model has the following beneficial effects: 1. By setting up a self-compensating cleaning unit, the contact and scraping between the cleaning component and the inner wall of the reactor effectively prevents scale formation on the inner wall of the reactor during the coagulation and hardening process, avoiding the impact of scale on the heat transfer efficiency and coagulation and hardening effect of the equipment, while reducing the difficulty of subsequent cleaning; and with the help of the elastic component, when the scraper in the cleaning component wears, it can automatically drive the scraper to move towards the inner wall of the reactor, ensuring that the scraper is always in contact with the inner wall and maintaining a stable cleaning effect, without the need for frequent manual adjustment or replacement of the scraper, thereby reducing maintenance costs and operational complexity; 2. By setting up a stirring unit, the power unit drives the stirring component to rotate, which can stir the high-hardness water in the reactor. This breaks up the temperature and concentration stratification that forms when the liquid is still, making the reaction and heating of the high-hardness water more uniform, thereby accelerating the reaction and water evaporation rate, shortening the coagulation and hardening cycle of the high-hardness water. The rotation of the stirring component can also promote the solid residue remaining in the reactor. Combined with the sewage discharge function of the sewage discharge unit, the residue can be discharged from the reactor more smoothly, reducing the amount of residue in the reactor and providing convenience for subsequent cleaning and next use of the equipment.

[0019] The self-compensating cleaning unit 2 includes several elastic components 21, all of which are disposed within the reactor 111; a support component 22, which is installed within the reactor 111; and several cleaning components 23, which are also disposed within the reactor 111. Each elastic component 21 includes a slide rod 211 disposed within the reactor 111, with a limit block 212 fixedly connected to its outer wall, and a spring 213 sleeved on its outer wall. There are sixteen elastic components 21 and eight cleaning components 23. The support component 22 includes a support frame 221 rotatably connected to the inner wall of the reactor 111. Several rectangular plates 222 are disposed within the reactor 111. The side of the slide rod 211 closest to the rectangular plate 222 is fixedly connected to it, while the side of the slide rod 211 furthest from the rectangular plate 222 slides through the support frame 221. 21. The side of spring 213 closest to rectangular plate 222 is fixedly connected to rectangular plate 222, and the side of spring 213 away from rectangular plate 222 is fixedly connected to support frame 221. Four rectangular plates 222 are provided, and four elastic components 21 and two cleaning components 23 are provided on each rectangular plate 222. The cleaning component 23 includes a U-shaped block 231 fixedly connected to the side of rectangular plate 222 away from slide bar 211. A scraper 232 is installed on the U-shaped block 231. A stirring plate 233 is fixedly connected to the side of rectangular plate 222 away from rectangular plate 222. The side of scraper 232 away from rectangular plate 222 is in contact with the inner wall of reactor 111. By setting a self-compensating cleaning part 2, the scraper 232 is automatically driven to move towards the inner wall of reactor 111, ensuring that the scraper 232 is always in contact with the inner wall and maintaining a stable cleaning effect. There is no need for frequent manual adjustment or replacement of scraper 232, thereby reducing maintenance costs and operational complexity.

[0020] The stirring unit 3 includes a power assembly 31, which is disposed on the inner wall of the reactor 111; and several stirring assemblies 32, which are arranged in a circular array inside the reactor 111. The power assembly 31 includes a motor 311 fixedly connected to the right side of the reactor 111. The output shaft of the motor 311 is fixedly connected to a rotating shaft 312 via a coupling. The left side of the rotating shaft 312 extends into the reactor 111 and passes through and is fixedly connected to the support frame 221. 2 is rotatably connected to the reactor 111. The stirring assembly 32 includes several connecting rods 321 fixedly connected to the outer wall of the rotating shaft 312. The connecting rods 321 are fixedly connected to a spiral blade 322 on the side away from the rotating shaft 312. By setting the stirring part 3, the high-hardness water in the reactor 111 can be stirred, thereby breaking the temperature and concentration stratification formed when the liquid is stationary, making the high-hardness water react and heat more evenly, thereby accelerating the reaction and water evaporation rate, and shortening the coagulation and hardening cycle of the high-hardness water.

[0021] A specific application of this embodiment is as follows: In use, the steam pipe 112 is connected to the condenser, and high-hardness water and coagulant are injected into the reactor 111 through the feed pipe 113. After the liquid volume reaches the set amount, the feed pipe 113 is closed, and the motor 311 is started with a delay. The motor 311 drives the support frame 221 to rotate through the rotating shaft 312. The support frame 221 drives the rectangular plate 222 to move in a circular motion around the rotating shaft 312 through the slide rod 211. The rectangular plate 222 drives the scraper 232 to scrape the inner wall of the reactor 111 through the U-shaped block 231, thereby preventing scale buildup on the inner wall of the reactor 111. When the inner wall of the scraper 232 is worn, the spring 213 will rebound and extend, causing the slide rod 211 to move radially closer to the inner wall of the reactor 111. Thus, the scraper 232 continues to move in a circular motion through the U-shaped block 231. The inner wall of the reactor 111 is fitted to the surface, completing the self-compensation for the wear of the scraper 232. At the same time, the rotating shaft 312 drives the spiral blades 322 to rotate around the rotating shaft 312 through several connecting rods 321, stirring the liquid in the steam pipe 112. After the hardening ions in the water react, steam is generated below the reactor 111 through the steam valve, causing the temperature of the liquid in the reactor 111 to rise to boiling. The water in the liquid begins to evaporate, and the water vapor enters the condenser through the steam pipe 112 and is condensed into liquid water for recovery. After the equipment distillation is completed, the steam valve is closed, and the pull rod 117 is pulled to the left, causing the pull rod 117 to move the pipe cover 116 to the right until the pipe cover 116 separates from the drain pipe 114. The spiral blades 322 of several stirring components 32 rotate to discharge the residue in the tank, thereby completing the coagulation and hardening removal of high-hardness water.
