Description
Technical Field
[0001] This utility model relates to the field of high-efficiency demulsifier production technology, and in particular to a high-efficiency demulsifier mixing and stirring device. Background Technology
[0002] In many industries such as petroleum, chemical, food, and water treatment, the presence of emulsions often leads to reduced efficiency and waste of resources in the production process. Emulsions are suspension systems formed by two immiscible liquids, and their stability makes the separation process complex. To solve this problem, the use of demulsifiers has gradually become a common practice in the industry. Demulsifiers are chemical substances used to break the emulsion state in emulsions. However, the addition and mixing process of demulsifiers has a significant impact on the demulsification effect. Therefore, it is particularly important to develop an efficient demulsifier mixing and stirring device.
[0003] In practical applications, traditional demulsifier mixing devices typically involve pouring the demulsifier and emulsion together into the mixing drum. This method often results in uneven material distribution during mixing, especially when processing high-viscosity or large-particle materials. Uneven mixing not only affects the effectiveness and demulsification effect of the demulsifier but may also reduce the separation efficiency of the emulsion, thereby increasing the difficulty and cost of subsequent processing. Furthermore, traditional mixing devices usually employ a shaft-mixing rod structure, with the mixing rod and shaft integrated. This design makes cleaning after use very inconvenient. Since the mixing rod cannot be disassembled, residual substances are difficult to remove completely, posing hygiene risks for subsequent operations and potentially causing cross-contamination in the next mixing cycle. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient demulsifier mixing and stirring device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-efficiency demulsifier mixing and stirring device includes a stirring drum. A drum cover is provided at the top of the drum. Two fixing mechanisms for fixing the drum cover are symmetrically arranged on the outer wall of the drum cover. A feed hopper is fixed at the top of the drum cover, and the discharge end of the feed hopper extends through the bottom of the drum cover. A second disc is fixed on the inner wall of the feed hopper near the discharge end. Multiple second through holes are opened at the top of the second disc. An adjusting mechanism for adjusting the size of the multiple second through holes is provided inside the feed hopper. A column is fixed at the middle of the bottom of the stirring drum. A rotating shaft is provided at the top of the column. A circular groove is opened at the bottom of the rotating shaft, and the circular groove is adapted to the column. A rotating mechanism for rotating the rotating shaft is provided at the top of the drum cover. Multiple annular sleeves are fitted on the side wall of the rotating shaft. A sleeve is provided between every two annular sleeves, and multiple sleeves are fitted onto the side wall of the rotating shaft. The inner wall of each of the annular sleeves is provided with a mechanism for limiting the annular rings. The device incorporates a rotation limiting mechanism. Multiple rotating shafts are symmetrically fixed to their outer side walls with stirring rods arranged in two groups. The inner side wall of the mixing drum is equipped with two arc-shaped scrapers, each with a locking mechanism for engaging the two scrapers. During cleaning, by releasing the two fixing mechanisms from the drum cover, the mixing drum and cover can be quickly separated, allowing for modular processing of the device. This facilitates cleaning, avoids hygiene hazards in subsequent operations, and prevents cross-contamination during the next mixing cycle. The feed hopper allows for preliminary mixing of the demulsifier and emulsion. The rotating mechanism drives the first disc to rotate, causing misalignment of multiple first and second through holes, reducing the speed at which the demulsifier and emulsion enter the mixing drum. This ensures thorough mixing of the demulsifier and emulsion, improving the mixing effect.
[0007] Preferably, the adjusting mechanism includes a connecting plate fixed to the inner wall of the feed hopper. A connecting rod is inserted through the top center of the connecting plate. An annular plate is sleeved on the side wall of the connecting rod, and the annular plate is located below the connecting plate. A first disc is provided on the top of the second disc. The top of the first disc has multiple second through holes, and the multiple second through holes correspond one-to-one with the multiple first through holes. A sleeve is fixed at the top center of the first disc. A circular slider is slidably connected to the inner wall of the sleeve, and the circular slider is fixed to the bottom end of the connecting rod. The sleeve is equipped with... A first spring is provided, with one end of the first spring fixed to a circular slider and the other end fixed to a sleeve. By rotating the connecting rod in conjunction with the circular slider and the first spring, the sleeve is driven to rotate. The rotation of the sleeve drives the first disc to rotate. At this time, multiple first through holes and multiple second through holes are misaligned, allowing the pre-mixed demulsifier and emulsion to drip slowly into the mixing tank. This avoids pouring the demulsifier and emulsion into the mixing tank at once for mixing, preventing a decrease in the effectiveness and demulsification effect of the demulsifier and improving the separation efficiency of the emulsion.
[0008] Preferably, the rotating mechanism includes a motor, which is fixed at the center of the top of the cylinder cover. A rectangular block is provided at the bottom of the cylinder cover, and the rectangular block is fixed to the output shaft of the motor. A rectangular hole is provided at the top of the rotating shaft, and the rectangular hole is adapted to the rectangular block. The limiting mechanism includes two protrusions, which are symmetrically fixed on the inner sidewall of one of the annular sleeves. Two grooves are provided on the sidewall of the rotating shaft, and the two grooves are adapted to the two protrusions respectively. The driving motor drives the rectangular block to rotate, which in turn drives the rotating shaft to rotate in conjunction with the rectangular hole. When the rotating shaft rotates, it drives multiple stirring rods to rotate under the action of the two grooves, multiple protrusions and multiple annular sleeves, thereby stirring and mixing the demulsifier and the emulsion.
[0009] Preferably, the fixing mechanism includes a support plate fixed to the side wall of the cylinder cover. A pin is fixed to the bottom of the support plate. A groove is formed on the side wall of the pin, and the groove has a constricted structure. A rectangular slider is slidably connected to the side wall of the groove. A locking block is fixed to one end of the rectangular slider. A second spring is provided inside the groove and is located at the other end of the rectangular slider. A U-shaped plate is fixed to the outer wall of the mixing cylinder, and the U-shaped plate is adapted to the pin. By pressing the two locking blocks, the two rectangular sliders move along the inner side walls of the two grooves respectively until the two locking blocks retract into the two grooves respectively. At this time, the cylinder cover is moved upward, and the two support plates drive the two pins to disengage from the two U-shaped plates respectively. This releases the fixing of the cylinder cover and allows the cylinder cover to be removed from the top of the mixing cylinder.
[0010] Preferably, the snap-fit mechanism includes a T-shaped block, which is fixed to the side wall of one of the arc-shaped scrapers. One end of each of the set of stirring rods is provided with a T-shaped groove, and multiple T-shaped grooves are adapted to the T-shaped block. By setting two T-shaped blocks and multiple T-shaped grooves, the installation or disassembly of two arc-shaped scrapers and multiple stirring rods can be completed quickly.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. During the cleaning process, the mixing drum and the drum cover can be quickly separated by releasing the two fixing mechanisms, which allows for modular processing of the device, facilitating cleaning and avoiding hygiene hazards in subsequent operations, as well as preventing cross-contamination during the next mixing.
[0013] 2. The feed hopper allows for preliminary mixing of the demulsifier and emulsion. Combined with the rotating mechanism that drives the first disc to rotate, multiple first and second through holes are misaligned, reducing the speed at which the demulsifier and emulsion enter the mixing drum. This ensures thorough mixing of the demulsifier and emulsion, improving the mixing effect. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figure 1 - Figure 10 A high-efficiency demulsifier mixing and stirring device includes a mixing drum 1, a drum cover 2 on the top of the mixing drum 1, two fixing mechanisms symmetrically arranged on the outer wall of the drum cover 2 for fixing the drum cover 2, a feed hopper 4 fixed on the top of the drum cover 2, and the discharge end of the feed hopper 4 penetrating through the bottom of the drum cover 2. A second disc 11 is fixed on the inner wall of the feed hopper 4 near the discharge end, and the top of the second disc 11 has multiple second through holes 16. The feed hopper 4 is provided with an adjustment mechanism for adjusting the size of the multiple second through holes 16. The mixing drum 1 has a regulating mechanism. A column 28 is fixed at the bottom center of the mixing drum 1. A rotating shaft 17 is mounted on top of the column 28. A circular groove 29 is formed at the bottom of the rotating shaft 17, and the groove 29 is adapted to the column 28. A rotating mechanism for rotating the rotating shaft 17 is mounted on the top of the drum cover 2. Multiple annular sleeves 18 are fitted onto the sidewalls of the rotating shaft 17. A sleeve 21 is positioned between every two annular sleeves 18, and all sleeves 21 are fitted onto the sidewalls of the rotating shaft 17. The inner sidewalls of the multiple annular sleeves 18 are provided with limiting... A rotating limiting mechanism is provided for the ring sleeve 18. Multiple rotating shafts 17 are symmetrically fixed to the outer walls on both sides with stirring rods 19, arranged in two groups. Two arc-shaped scrapers 20 are provided on the inner wall of the mixing drum 1, and each arc-shaped scraper 20 has a locking mechanism for engaging the two scrapers. During cleaning, by releasing the two fixing mechanisms from the drum cover 2, the mixing drum 1 and drum cover 2 can be quickly separated, allowing for modular processing of the device, facilitating cleaning, avoiding hygiene hazards in subsequent operations, and preventing cross-contamination during the next mixing. The feed hopper 4 allows for preliminary mixing of the demulsifier and emulsion. The rotating mechanism drives the first disc 10 to rotate, causing the multiple first through holes 15 and multiple second through holes 16 to misalign, reducing the speed at which the demulsifier and emulsion enter the mixing drum 1. This ensures thorough mixing of the demulsifier and emulsion, improving the mixing effect.
[0027] Furthermore, the adjusting mechanism includes a connecting plate 7, which is fixed to the inner wall of the feed hopper 4. A connecting rod 8 is inserted through the middle of the top of the connecting plate 7. An annular plate 12 is sleeved on the side wall of the connecting rod 8, and the annular plate 12 is located below the connecting plate 7. A first disc 10 is provided on the top of the second disc 11. The top of the first disc 10 has multiple second through holes 16, and the multiple second through holes 16 correspond one-to-one with the multiple first through holes 15. A sleeve 9 is fixed at the middle of the top of the first disc 10. A circular slider 13 is slidably connected to the inner wall of the sleeve 9, and the circular slider 13 is fixed to the bottom end of the connecting rod 8. A second... A spring 14 is provided, with one end fixed to a circular slider 13 and the other end fixed to a sleeve 9. By rotating the connecting rod 8, the sleeve 9 is rotated in conjunction with the circular slider 13 and the first spring 14. The rotation of the sleeve 9 causes the first disc 10 to rotate. At this time, multiple first through holes 15 and multiple second through holes 16 are misaligned, allowing the pre-mixed demulsifier and emulsion to drip slowly into the mixing tank 1. This avoids pouring the demulsifier and emulsion into the mixing tank 1 at once for mixing, preventing a decrease in the effectiveness and demulsification effect of the demulsifier and improving the separation efficiency of the emulsion.
[0028] Furthermore, the rotating mechanism includes a motor 3, which is fixed at the top center of the cylinder cover 2. A rectangular block 27 is provided at the bottom of the cylinder cover 2, and the rectangular block 27 is fixed to the output shaft of the motor 3. A rectangular hole 24 is provided at the top of the rotating shaft 17, and the rectangular hole 24 is adapted to the rectangular block 27. The limiting mechanism includes two protrusions 22, which are symmetrically fixed on the inner side wall of one of the annular sleeves 18. Two grooves 23 are provided on the side wall of the rotating shaft 17, and the two grooves 23 are adapted to the two protrusions 22 respectively. The drive motor 3 drives the rectangular block 27 to rotate, which in turn drives the rotating shaft 17 to rotate in conjunction with the rectangular hole 24. When the rotating shaft 17 rotates, it drives multiple stirring rods 19 to rotate under the action of the two grooves 23, multiple protrusions 22 and multiple annular sleeves 18, thereby stirring and mixing the demulsifier and the emulsion.
[0029] Furthermore, the fixing mechanism includes a support plate 5, which is fixed to the side wall of the cylinder cover 2. A pin 6 is fixed to the bottom of the support plate 5. A groove 31 is provided on the side wall of the pin 6, and the groove 31 has a constricted structure. A rectangular slider 32 is slidably connected to the side wall of the groove 31. A locking block 33 is fixed to one end of the rectangular slider 32. A second spring 34 is provided inside the groove 31, and the second spring 34 is located at the other end of the rectangular slider 32. A U-shaped plate 30 is fixed to the outer wall of the mixing drum 1, and the U-shaped plate 30 is adapted to the pin 6. By pressing the two locking blocks 33, the two rectangular sliders 32 move along the inner side wall of the two grooves 31 respectively until the two locking blocks 33 retract into the two grooves 31 respectively. At this time, the cylinder cover 2 is moved upward, and the two support plates 5 drive the two pins 6 to disengage from the two U-shaped plates 30 respectively. In this way, the fixing of the cylinder cover 2 can be released, and the cylinder cover 2 can be removed from the top of the mixing drum 1.
[0030] Furthermore, the snap-fit mechanism includes a T-shaped block 25, which is fixed to the side wall of one of the arc-shaped scrapers 20. One end of each set of stirring rods 19 is provided with a T-shaped groove 26, and multiple T-shaped grooves 26 are adapted to the T-shaped block 25. With the setting of two T-shaped blocks 25 and multiple T-shaped grooves 26, the installation or disassembly of the two arc-shaped scrapers 20 and multiple stirring rods 19 can be completed quickly.
[0031] Working Principle: During operation, the demulsifier and emulsion are first poured into the feed hopper 4 for preliminary mixing. The connecting rod 8, in conjunction with the circular slider 13 and the first spring 14, rotates the sleeve 9. This rotation of the sleeve 9, in turn, rotates the first disc 10. At this time, the multiple first through holes 15 and multiple second through holes 16 are misaligned, allowing the pre-mixed demulsifier and emulsion to slowly drip into the mixing drum 1. This avoids pouring the demulsifier and emulsion into the mixing drum 1 all at once for mixing, preventing any impact on the effectiveness and demulsification effect of the demulsifier. To improve the separation efficiency of the emulsion, during stirring, the power switch of motor 3 is turned on, driving motor 3 to rotate rectangular block 27, which in turn drives shaft 17 to rotate in conjunction with rectangular hole 24. When shaft 17 rotates, under the action of two grooves 23, multiple protrusions 22, and multiple annular sleeves 18, multiple stirring rods 19 are driven to rotate, stirring and mixing the demulsifier and emulsion. At the same time as the multiple stirring rods 19 rotate, in conjunction with two T-shaped blocks 25 and multiple T-shaped grooves 26, two arc-shaped scrapers 20 move circumferentially along the inner wall of stirring drum 1, scraping and cleaning the inner wall of stirring drum 1. To prevent the emulsion from sticking to the inner wall of the mixing drum 1 and further improve the mixing effect, after mixing, remove the connecting rod 8, sleeve 9 and first disc 10 as a whole from the feed hopper 4. Press the two locking blocks 33 to make the two rectangular sliders 32 move along the inner walls of the two sliding grooves 31 until the two locking blocks 33 retract into the two sliding grooves 31. At this time, move the drum cover 2 upward, and with the help of the two support plates 5, drive the two pins 6 to disengage from the two U-shaped plates 30. This releases the fixation of the drum cover 2. Remove the drum cover 2 from the top of the mixing drum 1. At this time, pull The rotating shaft 17 moves upward, causing the column 28 and the circular groove 29 to separate. The rotating shaft 17 is then removed from the mixing drum 1. After removal, the two T-shaped blocks 25 are pulled out from the multiple T-shaped grooves 26 to complete the disassembly of the two arc-shaped scrapers 20. Then, the multiple annular sleeves 18 and multiple sleeves 21 are removed one by one from the side wall of the rotating shaft 17, thereby completing the disassembly of the multiple stirring rods 19 and the rotating shaft 17. This modularizes the device, making it easier to clean later, avoiding hygiene hazards for subsequent operations, and preventing cross-contamination during the next mixing.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
