Description

Technical Field

[0001] This utility model discloses a glue mixing device, which belongs to the technical field of stator bar installation equipment for hydro generators. Background Technology

[0002] Stator bars are a crucial component of the stator in a hydro-generator unit. Their installation involves the use of various adhesives and semiconductor putties, which are multi-component solid and liquid mixtures. The traditional method for preparing these adhesives involves weighing and mixing them according to a specified ratio using an electronic scale, followed by manual stirring with a stirring rod until homogeneous and free of air bubbles. The main drawbacks of this method are as follows:

[0003] (1) When various materials are weighed and mixed using an electronic scale, the specific gravity of each material cannot be precisely controlled;

[0004] (2) Manual stirring takes a long time, is labor-intensive, and has high labor costs and low efficiency;

[0005] (3) The stirring time and stirring rate cannot be precisely controlled, making it impossible to ensure the consistency of stirring quality;

[0006] (4) During the stirring process, air bubbles are easily mixed into the paint and cannot be discharged.

[0007] Therefore, it is necessary to research an intelligent adhesive mixing device to achieve automatic weighing and mixing of various materials, visually stir the materials using a mixer, and remove air bubbles from the adhesive solution by vacuuming. The optimal stirring time and rate will be calculated based on experiments to ensure consistent mixing quality; simultaneously, stirring efficiency will be improved, saving manpower and resources.

[0035] The number of threaded push rods 17 is ≥2;

[0036] The height of the inner tub (16) is less than the height of the outer tub (8).

[0037] The top of the stirring shaft 14 is connected to the motor 7, the motor 7 is connected to the lifting platform 4, the lifting platform 4 is sleeved on the outside of the support column 3, and the bottom of the support column 3 is connected to the base 1.

[0038] The bottom of the outer barrel 8 is connected to a weighing device 2, which is placed above the base 1.

[0039] The outer barrel 8 is connected to a fixing plate 11 on the outside. The inner curvature of the fixing plate 11 is consistent with the curvature at the junction of the outer barrel 8. The fixing plate 11 is connected to the base 1 through a connecting rod 19. The top of the barrel lid 9 is provided with a pressure plate 12. The left and right ends of the pressure plate 12 are connected to pull rods 10, and the pull rods 10 are connected to the base 1.

[0040] The support column 3 is provided with a rack 5 on its side, and the lifting platform 4 is provided with a transmission device 18 on its inner side. The rack 5 meshes with the transmission device 18.

[0041] The transmission device 18 is a gear or a worm gear.

[0042] The lifting platform 4 is connected to a rocker wheel 6 on its outer side, and the rocker wheel 6 is connected to a transmission device 18.

[0043] The outer barrel 8 is connected to the vacuum tube 13; one end of the vacuum tube 13 is inside the outer barrel 8, and the other end is connected to the vacuum pump.

[0044] The base 1 is connected to a handrail 20 at the top and a roller 21 at the bottom; the support column 3 is rotatably connected to the base 1.

[0045] The bucket lid 9 is made of plexiglass; the weighing device 2 is an electronic scale; sealing gaskets are provided at the joints between the bucket lid 9 and the threaded rod 17 and the outer bucket 8; a sealing gasket is installed between the stirring shaft 14 and the bucket lid 9.

[0046] Example 2

[0047] The working principle of this utility model is as follows:

[0048] The inner bucket 16 (a paint bucket can be used) is detachable and placed inside the outer bucket 8 during use. Threaded push rods 17 are symmetrically arranged for coaxial positioning, and the threaded push rods 17 abut against the outer wall of the inner bucket 16. The inner bucket 16 and the outer bucket 8 are connected at the top and have the same air pressure. The materials to be mixed are loaded into the inner bucket 16 according to the mixing ratio, and the amount added is determined by reading the weighing device 2. The bucket lid 9 is placed on top of the outer bucket 8, and the pressure plate 12 is tightened at both ends by pull rods 10, thereby applying downward pressure to the outer bucket 8. Fixing plates 11 are symmetrically arranged on both sides of the outer bucket 8, providing stable support for the outer bucket 8.

[0049] The stirring shaft 14 moves through the barrel cover 9, and a sealing ring is installed between the stirring shaft 14 and the barrel cover 9. The height of the stirring impeller 15 is adjusted by the lifting platform 4. Specifically, rotating the rocker wheel 6 drives the transmission device 18 (gear or worm gear) to rotate. The transmission device 18 meshes with the rack 5 and is connected to the lifting platform 4, thereby driving the lifting platform 4 to move up and down, thus realizing the height adjustment of the stirring impeller 15. The stirring impeller 15 extends into the material in the inner barrel 16.

[0050] After the height of the stirring impeller 15 is adjusted, the vacuum pump is turned on: the external vacuum pump is connected to the outer barrel 8 through the vacuum pipe 13. The vacuum pump is started to draw a vacuum inside the outer barrel 8, so that the interior of the outer barrel 8 and the inner barrel 16 are in a negative pressure state, forming a vacuum effect, which is used to simultaneously draw a vacuum (1Kpa) to remove air bubbles in the adhesive during the stirring process.

[0051] The lid 9 is made of acrylic glass, which allows for visualization of the stirring process.

[0052] After mixing is complete, remove the vacuum pump and allow the pressure inside the barrel to gradually return to normal pressure; turn the rocker wheel 6, the lifting platform 4 rises, and the barrel cover 9 is lifted; after the mixing impeller 15 rises above the outer barrel 8, turn the support column 3 left and right, and the mixing mechanism deviates from the top of the outer barrel 8; take out the inner barrel 16 and pour out the mixed adhesive.

[0053] The rollers 21 at the bottom of the base 1 can be used to move the stirring device. The rollers 21 are self-locking rollers.

[0054] This device is also equipped with a timing device, which makes it convenient for operators to accurately mix and stir the insulating adhesive at set times, saving manpower, eliminating the uncertainty of manual stirring, and achieving controllable quality of the insulating adhesive preparation.

[0055] Due to the high viscosity of the adhesive, motor 7 is a variable speed, high torque servo motor, which can achieve stepless speed regulation through a frequency converter. The control box integrates functions such as alarm stop, timing, speed regulation and tare weighing display.

[0056] Weighing device 2 is an electronic scale with four gravity sensors installed at its bottom. The measurement range is 0-20kg and the accuracy is 2g. To ensure measurement accuracy, four sensors are symmetrically installed at the bottom. The calculated weight is displayed on the screen, which displays the weight in two modes: total weight and tare weight.

[0057] The base 1 and armrest 20 are made of stainless steel.
