Abstract
Description
Technical Field
[0001] This utility model relates to the field of continuous production technology of drilling fluid inhibitors, specifically a mixer for continuous production of drilling fluid inhibitors. Background Technology
[0002] Drilling fluid inhibitors, also known as anti-collapse agents, are treatment agents that can inhibit the hydration, expansion, and dispersion of shale. The mixers used in the continuous production of drilling fluid inhibitors need to meet requirements such as high efficiency, stability, and durability to ensure the smooth progress of the production process and the consistency of product quality.
[0003] Existing mixers used for producing drilling fluid inhibitors employ a single-axis, unidirectional rotation method to rotate fixed-position stirring blades, achieving mixing of drilling fluid inhibitor raw materials. However, the fixed coverage area of the stirring blades limits the mixing effect on the drilling fluid inhibitor raw materials, affecting the mixing efficiency. Furthermore, the mixed drilling fluid inhibitor needs to be removed before it can be discharged, which cannot guarantee continuous production of drilling fluid inhibitors. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a mixer for continuous production of drilling fluid inhibitors. The mixing blades perform radial periodic motion during the revolution and mixing process, which greatly improves the mixing effect of inhibitor raw materials. At the same time, the spiral blades realize the active discharge of inhibitors, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a mixer for continuous production of drilling fluid inhibitors, comprising a mixing chamber, a rotating shaft rotatably connected inside the mixing chamber, rotating frames fixedly connected to both ends of the rotating shaft, and a mixing mechanism;
[0006] The stirring mechanism includes a slide rod, a fixed ring, a sliding ring, a connecting rod 1, a connecting rod 2, and a stirring blade. The slide rods are uniformly fixedly connected between two rotating frames. Sliding rings are slidably connected to both ends of the three slide rods. Connecting rods 2 are rotatably connected to the relative inner surfaces of the two sliding rings. A fixed ring is fixedly connected to the middle of the three slide rods. Connecting rods 1 are rotatably connected to both ends of the fixed ring. The ends of connecting rod 1 and the longitudinally adjacent connecting rod 2 away from the central axis of the rotation axis are rotatably connected to the end of the same stirring blade near the central axis of the rotation axis. The stirring blade performs radial periodic motion during the revolution stirring process, which greatly improves the mixing effect of the inhibitor raw materials. At the same time, the spiral blade realizes the active discharge of the inhibitor.
[0007] Furthermore, the stirring mechanism also includes a wave-shaped guide rail and a sliding ball. The wave-shaped guide rail is symmetrically arranged inside the stirring chamber. The inside of the wave-shaped guide rail is slidably connected with a uniformly distributed sliding ball. The end of the sliding ball near the central axis of the rotation shaft is fixedly connected to a radially connected sliding ring through a support plate, so as to realize the longitudinal periodic movement of the sliding ring.
[0008] Furthermore, a control switch group is provided at the lower end of the front surface of the mixing chamber. The input end of the control switch group is electrically connected to an external power source to control the operation of each electrical appliance.
[0009] Furthermore, a motor is installed at the front end of the mixing chamber. The rear end of the output shaft of the motor is fixedly connected to the front end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the control switch group to provide driving force for the mixing unit.
[0010] Furthermore, it also includes scrapers, which are uniformly and fixedly connected between two rotating frames. The end of the scraper away from the center of the mixing chamber is installed in conjunction with the inner wall of the mixing chamber to achieve mixing of the outer layer inside the mixing chamber, while preventing inhibitors from adhering to the inner wall of the mixing chamber.
[0011] Furthermore, a discharge hopper is provided at the rear end of the mixing chamber, and a rotating shaft is rotatably connected inside the discharge hopper. A spiral blade is provided in the middle of the rotating shaft. A second motor is provided at the rear end of the discharge hopper. The front end of the output shaft of the second motor is fixedly connected to the rear end of the rotating shaft. The input end of the second motor is electrically connected to the output end of the control switch group to realize the active discharge of the inhibitor.
[0012] Furthermore, the upper end of the mixing chamber is provided with a feed inlet, the rear end of the discharge chamber is provided with a discharge pipe, the middle of the discharge pipe is provided with an electric valve, the input end of the electric valve is electrically connected to the output end of the control switch group, and the lower end of the mixing chamber is fixedly connected with evenly distributed support legs to provide a channel for the inlet and outlet of the inhibitor.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This mixer for continuous production of drilling fluid inhibitors has the following advantages:
[0014] 1. The rotating frame rotates the stirring blades to work, while the sliding balls slide inside the wave-shaped guide rails, causing the linkage mechanism to operate. The operation of the linkage mechanism causes the radially adjacent stirring blades to perform radial periodic motion during the revolution and stirring process, which greatly improves the mixing effect of the inhibitor raw materials.
[0015] 2. The motor drives the spiral blade to rotate. The shearing force generated by the rotation of the spiral blade and the inner wall of the discharge hopper actively guides the inhibitor to the discharge port, effectively controlling the discharge rate of the inhibitor. This provides time for the full mixing of the inhibitor raw materials, eliminating the need to completely remove the mixed drilling fluid inhibitor. This allows for the addition of new raw materials for drilling fluid inhibitors, enabling continuous production of drilling fluid inhibitors. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-3 This embodiment provides a technical solution: a mixer for continuous production of drilling fluid inhibitors, including a mixing chamber 1, a rotating shaft 5 rotatably connected inside the mixing chamber 1, a rotating frame 4 fixedly connected to both the front and rear ends of the rotating shaft 5, a control switch group 11 provided at the lower end of the front surface of the mixing chamber 1, the input end of the control switch group 11 being electrically connected to an external power source, and a mixing mechanism 3.
[0022] The stirring mechanism 3 includes a slide rod 31, a fixed ring 32, a sliding ring 33, a first connecting rod 34, a second connecting rod 35, and a stirring blade 36. The slide rods 31 are evenly fixedly connected between the two rotating frames 4. The front and rear ends of the three slide rods 31 are slidably connected to the sliding rings 33. The inner surfaces of the two sliding rings 33 are rotatably connected to the evenly distributed second connecting rods 35. The middle of the three slide rods 31 is fixedly connected to the fixed ring 32. The front and rear ends of the fixed ring 32 are rotatably connected to the evenly distributed first connecting rods 34. The ends of the first connecting rod 34 and the longitudinally adjacent second connecting rod 35 away from the central axis of the rotating shaft 5 are connected to the end of the same stirring blade 36 near the central axis of the rotating shaft 5. The stirring mechanism 3 also includes a corrugated guide rail 37 and sliding balls 38. The corrugated guide rail 37 is symmetrically arranged inside the stirring chamber 1. Sliding balls 38 are evenly distributed inside each corrugated guide rail 37. The end of each sliding ball 38 near the central axis of the rotating shaft 5 is fixedly connected to a radially connected sliding ring 33 via a support plate. A motor 7 is located at the front end of the stirring chamber 1. The rear end of the output shaft of motor 7 is fixedly connected to the front end of the rotating shaft 5. The input end of motor 7 is electrically connected to the output end of the control switch group 11. The motor 7 is operated by the control switch group 11. The rotation of the output shaft of motor 7 drives the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the two rotating frames 4. The rotation of the slide rods 31 causes the evenly distributed slide rods 31 to rotate. Each slide rod 31 rotates around the central axis of the rotation axis 5. The rotation of the slide rods 31 causes the fixed ring 32 and the sliding ring 33 to rotate. The rotation of the sliding ring 33, through the support plate, causes the sliding balls 38 to rotate. Each sliding ball 38 slides inside the corresponding wave-shaped guide rail 37, causing the sliding rings 33 to move longitudinally and periodically under the guidance of the slide rods 31. When the sliding rings 33 move towards the center of the mixing chamber 1, the end of the connecting rod 35 that is away from the center of the mixing chamber 1 moves towards the center of the mixing chamber 1. This causes both connecting rod 34 and connecting rod 35 to rotate away from the center of the mixing chamber 1. 4 and the longitudinally adjacent connecting rod 2 35 at the end away from the center of the mixing chamber 1 both push the same stirring plate 36 to move away from the center of the mixing chamber 1. When the sliding ring 33 moves away from the center of the mixing chamber 1, it drives the end of connecting rod 2 35 away from the center of the mixing chamber 1 to move away from the center of the mixing chamber 1. This causes connecting rod 1 34 and connecting rod 2 35 to rotate towards the center of the mixing chamber 1. The ends of connecting rod 1 34 and the longitudinally adjacent connecting rod 2 35 at the end away from the center of the mixing chamber 1 both pull the same stirring plate 36 towards the center of the mixing chamber 1, realizing the radial periodic movement of the stirring plate 36, which greatly improves the mixing effect of the inhibitor raw material.
[0023] The scraper 6 is also included. The scraper 6 is evenly fixed between the two rotating frames 4. The end of the scraper 6 away from the center of the mixing chamber 1 is installed in conjunction with the inner wall of the mixing chamber 1. At the same time, the rotation of the rotating frame 4 drives the evenly distributed scraper 6 to rotate. The scraper 6 rotates around the central axis of the rotating shaft 5 to stir the inhibitor raw material in the outer layer of the mixing chamber 1, and at the same time scrape off the inhibitor attached to the inner wall of the mixing chamber 1.
[0024] The mixing chamber 1 is equipped with a discharge chamber 2 at its rear end. A rotating shaft 8 is rotatably connected inside the discharge chamber 2. A spiral blade 9 is installed in the middle of the rotating shaft 8. A second motor 10 is installed at the rear end of the discharge chamber 2. The front end of the output shaft of the second motor 10 is fixedly connected to the rear end of the rotating shaft 8. The input end of the second motor 10 is electrically connected to the output end of the control switch group 11. The second motor 10 is operated by the control switch group 11. The rotation of the output shaft of the second motor 10 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the spiral blade 9 to rotate. The shearing force generated by the spiral blade 9 and the inner wall of the discharge chamber 2 realizes the spiral conveying of the inhibitor and controls the discharge rate of the inhibitor. It is not necessary to completely remove the mixed drilling fluid inhibitor, thus ensuring the continuous production of drilling fluid inhibitor.
[0025] The mixing chamber 1 has an inlet at its upper end, through which the drilling fluid inhibitor raw material enters. The discharge chamber 2 has a discharge pipe at its rear end, and an electric valve 12 is installed in the middle of the discharge pipe. The input end of the electric valve 12 is electrically connected to the output end of the control switch group 11. The lower end of the mixing chamber 1 is fixedly connected with evenly distributed support legs. The electric valve 12 is operated by the control switch group 11. When the electric valve 12 is opened, the shear force generated by the spiral blade 9 and the inner wall of the discharge chamber 2 realizes the spiral conveying of the inhibitor, controls the discharge rate of the inhibitor, and finally removes the inhibitor through the discharge pipe. It is not necessary to completely remove the mixed drilling fluid inhibitor, thus ensuring the continuous production of drilling fluid inhibitor.
[0026] The working principle of the mixer for continuous production of drilling fluid inhibitors provided by this utility model is as follows: During operation, the operator first uses the outriggers to stably place the mixing chamber 1, the discharge chamber 2, and other mechanisms in a horizontal working area. After stable placement, the operator adds the drilling fluid inhibitor raw material into the mixing chamber 1 through the feed inlet. Then, the operator controls the switch group 11 to start the motor 7. The output shaft of the motor 7 rotates, driving the rotating shaft 5 to rotate. The rotating shaft 5 rotates, driving the two rotating frames 4 to rotate, which in turn drives the evenly distributed slide rods 31 to rotate. The slide rods 31 all rotate around the central axis of the rotating shaft 5. The rotation of the slide rods 31 drives the fixed ring... 32 and sliding ring 33 rotate. The rotation of sliding ring 33 drives the sliding ball 38 to rotate through the support plate. The sliding ball 38 slides inside the corresponding wave guide rail 37, so that the sliding ring 33 moves longitudinally periodically under the guidance of sliding rod 31. When the sliding ring 33 moves towards the center of the mixing chamber 1, it drives the end of connecting rod 2 35 away from the center of the mixing chamber 1 to move towards the center of the mixing chamber 1. This causes connecting rod 1 34 and connecting rod 2 35 to rotate away from the center of the mixing chamber 1. The ends of connecting rod 1 34 and the longitudinally adjacent connecting rod 2 35 away from the center of the mixing chamber 1 push the same mixing plate 36 to move away from the center of the mixing chamber 1. When the sliding rings 33 move away from the center of the mixing chamber 1, they cause the ends of the connecting rods 35 away from the center of the mixing chamber 1 to move away from the center of the mixing chamber 1. This causes the connecting rods 34 and 35 to rotate closer to the center of the mixing chamber 1. The ends of the connecting rods 34 and 35, which are longitudinally adjacent to the center of the mixing chamber 1, pull the same stirring blade 36 to move closer to the center of the mixing chamber 1, realizing the radial periodic movement of the stirring blade 36. This greatly improves the mixing effect of the inhibitor raw materials. At the same time, the rotation of the rotating frame 4 drives the evenly distributed scrapers 6 to rotate. The scrapers 6 rotate around the central axis of the rotating shaft 5, realizing the mixing effect of the mixing chamber 1. The inner and outer layers of inhibitor raw materials are stirred, and the inhibitor adhering to the inner wall of the stirring chamber 1 is scraped off. Then, the motor 10 is started by the control switch group 11. The output shaft of the motor 10 rotates, which drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the spiral blade 9 to rotate, thereby stirring the raw materials of the inhibitor. At the same time, the electric valve 12 is operated by the control switch group 11. When the electric valve 12 is opened, the shearing force generated by the spiral blade 9 and the inner wall of the discharge chamber 2 realizes the spiral conveying of the inhibitor and controls the discharge rate of the inhibitor. Finally, the inhibitor is removed through the discharge pipe. It is not necessary to completely remove the mixed drilling fluid inhibitor, which ensures the continuous production of drilling fluid inhibitor.
[0027] It is worth noting that the control switch group 11 disclosed in the above embodiments is provided with control buttons that correspond one-to-one with motor 7 and motor 2 10 and control their switching.
