Description

Technical Field

[0001] This application relates to the technical field of mixing devices for paint production, specifically a settling-preventing mixing device for paint production. Background Technology

[0002] In the paint production process, mixing is a crucial step, aiming to uniformly disperse components such as pigments, fillers, resins, and additives to form a stable and consistent fluid system. Existing paint mixing devices typically include a drive motor, a motor-driven mixing shaft, and a single-layer mixing paddle fixedly mounted on the mixing shaft.

[0003] However, since the agitator is usually located in the lower middle part of the tank, the mainstream flow field generated by its rotation mainly acts on the area directly swept by the blades. The coating located at the bottom of the tank, especially near the junction of the tank wall and the bottom, is most vulnerable to hydrodynamic forces and is prone to forming a relatively static "dead zone". Due to the lack of effective disturbance and upward fluid for a long time, the coating particles in this area are more likely to continuously contact and deposit on the inner wall of the tank bottom under the action of gravity. With the intermittent or stopped stirring, these particles in contact with the bottom of the tank will quickly settle and gradually harden, forming a hard sediment layer, which seriously damages the uniformity of the product.

[0004] Therefore, this application provides an anti-settling stirring device for paint production to solve the above-mentioned problems. Utility Model Content

[0005] This application provides an anti-settling stirring device for paint production, which aims to solve the problem mentioned in the background art that, due to the fact that the stirring paddle is usually located in the middle and lower part of the tank, uneven stirring causes the particles at the bottom of the tank to settle rapidly and gradually harden, forming a hard sediment layer.

[0006] To achieve the above objectives, this application provides the following technical solution: a sedimentation prevention stirring device for paint production, comprising a processing tank and a discharge pipe installed on the outside of the processing tank, wherein the lower end of the processing tank is provided with a plurality of support legs arranged in a ring, the upper end of the processing tank is detachably fitted with a cover, and a feeding pipe is provided on the processing tank, a servo motor is provided on the cover, and a shaft is detachably fitted on the output end of the servo motor; A stirring mechanism is provided on the shaft; The stirring mechanism includes two sets of disc seats equidistantly arranged on the shaft. Rod sleeve seats are symmetrically arranged on the disc seats. A stirring main rod is installed on the rod sleeve seats. Several auxiliary plates are sleeved on the stirring main rod. Connecting rings are symmetrically installed on the auxiliary plates. A stirring auxiliary rod is provided at the lower end of the disc seats. This solves the problem of single-layer stirring and easy sedimentation at the bottom in traditional stirring devices. Through the cooperation of the stirring main rod and the stirring auxiliary rod, stirring is carried out in the entire area of ​​the tank.

[0007] Preferably, threaded pins are symmetrically arranged on the rod sleeve seat, and the stirring main rod is inserted into the rod sleeve seat and fixed by the threaded pins.

[0008] Preferably, the connecting ring is serrated. The serrated structure can cut the agglomerated particles in the coating and generate local turbulence, breaking the adsorption force between particles and preventing particle agglomeration and sedimentation.

[0009] Preferably, the stirring rod is cross-shaped and is adapted to the inner wall of the bottom of the processing tank. An exhaust ring frame is provided on the stirring rod. A cross-shaped air guide pipe for fixed insertion with the exhaust ring frame is fixedly installed at the lower end of the shaft. Several bubble nozzles are evenly distributed on the upper part of the exhaust ring frame. A temperature sensor is provided inside the stirring rod. The diameter of the exhaust ring frame is adapted to the bottom of the processing tank, covering 87.5% of the bottom area. There are 18 bubble nozzles evenly distributed.

[0010] Preferably, a bubble generator is provided at the lower end of the processing tank, an exhaust pipe is fixedly installed at the output end of the bubble generator, the lower end of the shaft is rotatably connected to the processing tank, and the exhaust pipe of the bubble generator is connected to the lower end of the shaft.

[0011] Preferably, a cooling pipe is installed at the lower end of the processing tank, and an inlet and a outlet are installed opposite each other on the cooling pipe.

[0012] The mixing device has a disc base fixed on a shaft, a rod sleeve mounting the main mixing rod, and a secondary plate and connecting ring on the main mixing rod rotating with the shaft to mix and disperse the coating. Compressed air generated by the bubble generator is delivered to the lower end of the shaft through an exhaust pipe. The shaft has a hollow internal structure and is sealed to the processing tank. The air is then distributed to the exhaust ring frame through a cross-shaped air guide pipe and finally ejected from the bubble nozzle. The secondary mixing rod at the lower end of the disc base mixes the coating at the bottom of the processing tank to prevent sedimentation. The cooling pipe is a coil structure that surrounds the lower part of the processing tank to cool the coating in the lower half of the tank. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] This embodiment provides an anti-settling stirring device for paint production, such as... Figure 1-5 As shown, the stirring device includes a processing tank 1 and a discharge pipe 2 installed on the outside of the processing tank 1. The lower end of the processing tank 1 is provided with several support legs 3 arranged in a ring. The upper end of the processing tank 1 is detachably equipped with a cover 4. The processing tank 1 is provided with a feeding pipe. The cover 4 is equipped with a servo motor 5. The output end of the servo motor 5 is detachably equipped with a shaft 6. A stirring mechanism is installed on shaft 6; The stirring mechanism includes two sets of disc seats 61 equidistantly arranged on the shaft 6. Rod sleeve seats 62 are symmetrically arranged on the disc seats 61. A stirring main rod 63 is installed on the rod sleeve seats 62. Several auxiliary plates 64 are sleeved on the stirring main rod 63. Connecting rings 65 are symmetrically installed on the auxiliary plates 64. A stirring auxiliary rod 66 is provided at the lower end of the disc seats 61.

[0017] Specifically, the processing tank 1 provides a container for coating mixing, the discharge pipe 2 is used for finished product discharge, the support leg 3 supports the tank body, the cover 4 seals the tank body and is equipped with a servo motor 5, the servo motor 5 drives the shaft 6 to rotate, driving the mixing mechanism to work. In the mixing mechanism, the disc base 61 is fixed on the shaft 6, the rod sleeve base 62 is equipped with the mixing main rod 63, the auxiliary plate 64 and the connecting ring 65 on the mixing main rod 63 rotate with the shaft 6 to mix and disperse the coating, and the mixing auxiliary rod 66 at the lower end of the disc base 61 mixes the coating at the bottom of the processing tank 1. There are two sets of mixing main rod 63 and auxiliary plate 64 on the disc base 61, mainly arranged in the upper and middle parts of the tank body, while the auxiliary plate 64 is located at the bottom of the tank body, so as to achieve uniform mixing in the upper, middle and lower sections of the tank body and prevent sedimentation.

[0018] Threaded pins are symmetrically arranged on the rod sleeve seat 62. The stirring main rod 63 is inserted into the rod sleeve seat 62 and fixed by the threaded pins. The connecting ring 65 is serrated.

[0019] More specifically, the threaded pin on the rod sleeve 62 can quickly lock or unlock the stirring main rod 63 and adjust the angle of the stirring main rod 63 according to the stirring situation, thereby adjusting the stirring angle of the connecting ring 65 to adapt to coatings of different viscosities. During installation, the stirring main rod 63 is inserted into the rod sleeve 62 and the threaded pin is tightened to fix it. During disassembly, the threaded pin is loosened to pull out the stirring main rod 63. The threaded pin is of M10 specification and made of 304 stainless steel, which is corrosion resistant. The rod sleeve 62 is made of cast aluminum and the connecting ring 65 is serrated, which rotates with the stirring main rod 63.

[0020] The stirring rod 66 is cross-shaped and is adapted to the inner wall of the bottom of the processing tank 1. An exhaust ring frame 67 is provided on the stirring rod 66. A cross-shaped air guide pipe 68 for fixed insertion and fixing with the exhaust ring frame 67 is fixedly installed at the lower end of the shaft 6. Several bubble nozzles 69 are evenly distributed on the upper part of the exhaust ring frame 67. A temperature sensor is provided inside the stirring rod 66.

[0021] Furthermore, the cross-shaped stirring rod 66 rotates against the bottom inner wall of the processing tank 1, scraping the bottom coating to prevent sedimentation. The gas generated by the bubble generator 7 passes through the exhaust pipe, shaft 6, cross-shaped air guide pipe 68, and exhaust ring frame 67, and finally sprays out tiny bubbles from the bubble nozzle 69. When the bubbles rise, they drive the bottom coating to flow, further inhibiting sedimentation. The temperature sensor inside the stirring rod 66 monitors in real time the temperature rise of the stirring rod 66 due to its rotation against the bottom of the tank, preventing overheating and resin deterioration.

[0022] A bubble generator 7 is installed at the lower end of the processing tank 1. An exhaust pipe is fixedly installed at the output end of the bubble generator 7. The lower end of the shaft 6 is fitted and rotatably connected to the processing tank 1. The exhaust pipe of the bubble generator 7 is connected to the lower end of the shaft 6.

The shaft 6 has a hollow structure and is rotated and sealed with the processing tank 1. The compressed air is then distributed to the exhaust ring frame 67 through the cross air guide pipe 68 and finally sprayed out from the bubble nozzle 69.

[0024] A cooling pipe 8 is installed at the lower end of the processing tank 1, and an inlet and a outlet are installed on the cooling pipe 8.

[0025] It is worth mentioning that the cooling pipe 8 is a coil structure that surrounds the lower part of the processing tank 1. Cooling water or low-temperature medium is introduced through the water inlet. When the temperature of the coating in the lower half of the tank is too high, the cooling water absorbs heat and is discharged from the drain outlet, thereby cooling the coating.

[0026] In use, the disc base 61 is fixed on the shaft 6, and the rod sleeve 62 is equipped with the stirring main rod 63. The auxiliary plate 64 and connecting ring 65 on the stirring main rod 63 rotate with the shaft 6 to stir and disperse the coating. The compressed air generated by the bubble generator 7 is delivered to the lower end of the shaft 6 through the exhaust pipe. The shaft 6 has a hollow structure and is rotatably sealed with the processing tank 1. The air is then distributed to the exhaust ring frame 67 through the cross air guide pipe 68 and finally sprayed out from the bubble nozzle 69. The stirring auxiliary rod 66 at the lower end of the disc base 61 stirs the coating at the bottom of the processing tank 1 to prevent sedimentation. The cooling pipe 8 has a coil structure and surrounds the lower part of the processing tank 1 to cool the coating in the lower half of the tank.
