Description

Technical Field

[0001] This invention belongs to the field of mixing and stirring technology of phosphate-free water dispersants, specifically, it relates to a mixing and stirring device for phosphate-free water dispersants. Background Technology

[0002] The function of dispersants is to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modify the surface properties of pigment particles, and adjust the mobility of pigment particles. Specifically, this is reflected in the following aspects: shortening dispersion time, improving gloss, improving tinting strength and hiding power, improving color development and toning properties, preventing floating color and blooming, preventing flocculation, and preventing sedimentation. The production process of dispersants is relatively complex, requiring the raw materials to be hot-melted and stirred together.

[0003] Publication No. CN216964330U discloses a multi-stage stirring production device for low-phosphorus ash water dispersible agents. The device includes a housing, a motor fixedly mounted on the upper right side of the housing via bolts, and an adjusting wheel fixedly mounted on the motor's output end. A support rod is fixedly mounted on the upper inner wall of the middle part of the housing. A connecting block is connected to the outside of the support rod, with a connecting wheel fixedly mounted on the upper outer side and a receiving block fixedly mounted on the lower outer side. A transmission mechanism is provided at the lower end of the connecting block. A bearing block is fixedly mounted on the outside of the receiving block. The adjusting wheel and the connecting wheel are connected by meshing, and the connecting block inside the connecting wheel is rotatably connected to the support rod. This multi-stage stirring production device for low-phosphorus ash water dispersible agents facilitates multi-stage stirring of raw materials, avoids insufficient stirring, and improves the mixing effect between raw materials.

[0004] Existing mixing devices cannot clean the inner wall when mixing materials, and the mixture adheres to the side or bottom wall, making it inconvenient to clean later.

[0005] To address the aforementioned issues, this application proposes a mixing and stirring device for a phosphate-free water dispersant. Summary of the Invention

[0006] In view of the problems in the related technologies, the present invention proposes a mixing and stirring device without phosphorus ash water dispersant to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A mixing and stirring device for a phosphate-free water dispersible agent includes a mixing drum, a support leg mechanism at the bottom of the mixing drum, a discharge port connected to the bottom side of the mixing drum, a sealing cover installed at the top of the mixing drum, a feeding port at the top of the sealing cover, a power stirring mechanism on the sealing cover, and the bottom of the power stirring mechanism located inside the mixing drum.

[0008] Preferably, the support leg mechanism includes two hollow legs and two solid legs. The bottom of the two hollow legs is open and an electric push rod is provided inside. The bottom of the two electric push rods is provided with an anti-slip pad.

[0009] Two electric push rods push the anti-slip pad downwards, and the two hollow legs support and extend the length. The two solid legs serve as fulcrums, causing the mixing drum to tilt as a whole, with the discharge port facing downwards, making it easy to discharge the mixture inside the mixing drum.

[0010] Preferably, the power stirring mechanism includes an outer tube and a central shaft. The outer tube is vertically rotatably installed at the center of the sealing cover, and the central shaft is rotatably installed inside the outer tube. Spiral blades are installed on the outer side of the central shaft inside the mixing drum, and an inner wall cleaning unit is installed on the outer side of the outer tube.

[0011] The central shaft drives the spiral blades to rotate, which can lift the sediment mixture at the bottom of the mixing drum upwards.

[0012] Preferably, multiple agitators are installed on the outside of the central shaft inside the mixing drum, and the multiple agitators are spaced apart from the spiral blades.

[0013] The central shaft rotates, driving multiple agitators to stir the mixture inside the mixing drum.

[0014] Preferably, the inner wall cleaning unit includes a horizontal rod, which is fixedly installed on the outside of the outer tube. A side wall cleaning rod is fixedly installed at the outer end of the horizontal rod. The outer side of the side wall cleaning rod is arc-shaped and fits against the side wall of the mixing drum. A bottom wall cleaning rod is fixedly installed at the bottom of the side wall cleaning rod and contacts the bottom wall of the mixing drum.

[0015] The side wall cleaning rod is rotated by the horizontal rod through the outer tube to clean the side wall of the mixing drum. The side wall cleaning rod drives the bottom wall cleaning rod to clean the bottom wall of the mixing drum, thus preventing the mixture from adhering to the inner wall of the mixing drum and making it difficult to clean.

[0016] Preferably, an n-shaped frame is fixedly installed on the top of the sealing cover, a servo motor is installed on the outside of the n-shaped frame, a power shaft is installed on the output shaft of the servo motor, a first bevel gear is installed at the end of the power shaft, the top of the central shaft is rotatably installed with the n-shaped frame through a bearing, and a second bevel gear is sleeved on the outside of the central shaft, with the first bevel gear meshing with the second bevel gear.

[0017] A servo motor drives the power shaft to rotate, which in turn drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, and the second bevel gear drives the central shaft to rotate.

[0018] Preferably, a first reduction gear is sleeved on the outer side of the power shaft, and a second reduction gear is sleeved on the outer side of the outer tube. The first reduction gear meshes with the second reduction gear, and the diameter of the first reduction gear is smaller than the diameter of the second reduction gear.

[0019] The power shaft drives the second reduction gear to rotate slowly via the first reduction gear, which in turn drives the outer tube to rotate slowly. The rotational speed of the central shaft is greater than that of the outer tube.

[0020] In summary, the technical effects and advantages of this invention are as follows: A servo motor drives the power shaft to rotate, which in turn drives the central shaft to rotate via the first and second bevel gears. The central shaft then drives the spiral blades to rotate, which lifts the sedimented mixture at the bottom of the mixing drum upwards. The rotation of the central shaft also drives multiple agitators to stir the mixture inside the mixing drum. The power shaft drives the second reduction gear to rotate slowly via the first reduction gear, which in turn drives the outer tube to rotate slowly. The rotation speed of the central shaft is greater than that of the outer tube. The outer tube drives the side wall cleaning rod to rotate via the horizontal rod to clean the side wall of the mixing drum. The side wall cleaning rod drives the bottom wall cleaning rod to clean the bottom wall of the mixing drum, thus preventing the mixture from adhering to the inner wall of the mixing drum and making it difficult to clean. Two electric push rods push the anti-slip pad downwards, and two hollow legs support and extend the length. The two solid legs are used as fulcrums to tilt the mixing drum as a whole, with the discharge port facing downwards, so that the mixture inside the mixing drum can be easily discharged. This invention can stir and tilt the mixture upwards to avoid sedimentation and improve the mixing effect. It can also clean the inner wall of the mixing drum, preventing the mixture from adhering to the inner wall and making it difficult to clean. The pouring method controls the overall tilt of the mixing drum with the discharge port facing downwards, making it easy to export the mixture inside the mixing drum. Attached Figure Description
