Description

Technical Field

[0001] This utility model relates to the field of dispersion technology, and in particular to a water-based coating mixing device. Background Technology

[0002] In the preparation process of water-based coatings, when the raw materials are initially mixed, the water-based resin, deionized water and other base materials need to be put into the mixing tank first, and the disperser is turned on at low speed to stir so that the base material forms a uniform liquid environment. Then, pigments, fillers and additives are added in batches. The high-speed rotating blades of the disperser will generate strong shearing force to break up the agglomerated particles of pigments and fillers and make them evenly dispersed into the base material. Currently, when mixing raw materials for water-based coatings using a disperser, the mixing tank is directly protected to some extent. For example, the Chinese utility model patent disclosed in publication number CN220126098U, "A Coating Disperser," uses a retaining ring, support ring, guide rod, protective plate, and handle to protect the mixing port without affecting the normal operation of the mixing rod inside the mixing tank, preventing dust and other particles from falling into the tank. However, this protective mechanism is limited to the period when the raw materials are being mixed inside the tank. When manually pouring powdered raw materials such as barium sulfate and stone powder into mixing tanks, the fine and lightweight particles collide violently with the air as they fall from the hands or packaging bags. The small particles easily detach from the main raw material and suspend in the air, forming dust. The airflow generated by the falling powder can also blow some particles out of the tank. In addition, it is difficult to control the speed and angle when manually pouring, so the raw materials are prone to spillage and flying. These dispersed powders will float in the production environment, thus polluting the equipment and the ground. If operators inhale them, they will irritate the respiratory tract, and long-term exposure may damage the lungs and have adverse effects on their health. Utility Model Content

[0003] The purpose of this invention is to provide a water-based coating mixing device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water-based coating mixing device includes a base, on which a hydraulic station is fixedly connected. A hydraulic lifting column is fixedly connected to the base at the front of the hydraulic station. A transmission box is fixedly connected to one end of the piston rod of the hydraulic lifting column. A motor is fixedly connected to the transmission box at the rear of the hydraulic lifting column. A shaft seat is fixedly connected to the transmission box at the front of the hydraulic lifting column. A rotating shaft is rotatably connected inside the shaft seat. A pulley at one end of the rotating shaft is connected to a pulley at the output end of the motor via a belt drive. A dust removal mechanism is provided at the lower end of the shaft seat. The dust removal mechanism includes a connecting flange fixedly connected to the lower end of the shaft seat. Several cantilever arms are movably connected to the outside of the connecting flange. A dust removal pipe is movably connected to the end of each cantilever arm away from the connecting flange. A first wall-mounted cover is fixedly connected to the bottom of the dust removal pipe. The dust removal pipe communicates with the inner cavity of the first wall-mounted cover and is fixedly connected to several sealing rings. A connecting pipe is movably connected between two adjacent dust removal pipes, and a second wall-mounted cover is fixedly connected to the bottom of the connecting pipe.

[0005] As a further preferred embodiment of this utility model, a number of first C-shaped shaft brackets are fixedly connected to the outside of the connecting flange to provide an installation base for the first arm body in the cantilever. The foundation setting height of the entire dust removal mechanism can be adjusted by adding connecting columns of different heights between the connecting flange and the shaft seat.

[0006] As a further preferred embodiment of this utility model, the cantilever includes a first arm body and a second arm body. One end of the first arm body is rotatably connected to one of the first C-shaped shaft frames. Both ends of the second arm body are fixedly connected to second C-shaped shaft frames. The second arm body is rotatably connected to one end of the first arm body through one of the second C-shaped shaft frames. After the first arm body and the second arm body are rotatably connected to each other, the end of the first arm body away from the second arm body is rotatably connected to the first C-shaped shaft frame. This allows for angle adjustment between the first arm body and the second arm body, thereby horizontally adjusting the distance between one set of dust removal pipes, the first wall cover, and the connecting flange. This allows for adjusting the diameter of the assembly formed by several dust removal pipes, the first wall cover, the connecting pipe, and the second wall cover to adapt to mixing tanks of different diameters.

[0007] As a further preferred embodiment of this utility model, a plurality of first dust suction ports are provided on one side of the first wall-mounted cover to suck up the floating dust near the mixing barrel opening into the dust removal pipe. A fixed base is fixedly connected to the center of the upper end of the dust removal pipe. The fixed base is rotatably connected to a second C-shaped shaft at one end of one of the second arms. A dust removal pipe connector is fixedly connected to one side of the dust removal pipe. The dust removal pipe connector is connected to the input end of an external dust removal device through a pipeline. By setting a plurality of first and second wall-mounted covers along the axial direction of the mixing barrel opening, and cooperating with the negative pressure suction of the external dust removal device, the floating dust generated when pouring raw materials can be sucked away.

[0008] As a further preferred embodiment of this utility model, a reinforcing steel sheet is fixedly connected inside the sealing ring, and several internal threaded groove blocks are fixedly connected to the outside of the reinforcing steel sheet. The outer surface of the sealing ring is wrapped with sealing rubber, and a fixing screw is threadedly connected between the internal threaded groove block and the dust removal pipe. The sealing ring with the reinforcing steel sheet inside can improve the overall structural strength, thereby facilitating its fixing inside the dust removal pipe with screws, and providing sealing and damping functions for the connection of the dust removal pipe, the first wall cover and the connecting pipe, and the second wall cover.

[0009] As a further preferred embodiment of this utility model, the connecting pipe is connected to the inner cavity of the second wall cover. The longitudinal cross-sectional dimensions of the connecting pipe and the second wall cover are smaller than those of the dust removal pipe and the first wall cover. The two ends of the connecting pipe and the second wall cover are respectively inserted into the sealing rings inside one set of dust removal pipes and the first wall cover. Several second suction ports are opened on one side of the second wall cover. The combination of the connecting pipe and the second wall cover connects two adjacent connecting pipes to the cavity inside the second wall cover. The flexible connecting pipe and the second wall cover can adapt to the horizontal position adjustment of the dust removal pipe and the first wall cover, ensuring the connectivity between the three sets of connecting pipes and the cavity inside the second wall cover, thereby realizing circumferential dust suction along the mixing barrel opening.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this utility model, a connecting flange is provided at the lower end of the shaft seat. The connecting flange is composed of several sets of interconnected dust removal pipes, first wall-mounted covers and connecting pipes, and second wall-mounted covers. This allows several first wall-mounted covers and second wall-mounted covers to be distributed circumferentially inside the mixing tank. With the negative pressure suction of the external dust removal equipment, the floating dust generated during dumping can be quickly removed, avoiding pollution of the production environment and harm to the health of operators. At the same time, with the help of several cantilever arms, the diameter of the dust removal pipe, first wall-mounted cover and connecting pipe, and second wall-mounted cover assembly can be flexibly adjusted to adapt to different specifications of mixing tanks.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5 As shown, the present invention provides a water-based coating mixing device, including a base 1, a hydraulic station 2 fixedly connected to the base 1, a hydraulic lifting column 3 fixedly connected to the base 1 in front of the hydraulic station 2, a transmission box 4 fixedly connected to one end of the piston rod of the hydraulic lifting column 3, a motor 5 fixedly connected to the transmission box 4 in the transmission box 4 in the transmission box 4 in the transmission box 4 in the transmission box 4 in the transmission box 4 in the transmission box 3, a shaft seat 6 fixedly connected to the shaft seat 6, and a rotating shaft 7 rotatably connected inside the shaft seat 6. A pulley at one end of the rotating shaft 7 is connected to the pulley at the output end of the motor 5 via a belt drive. A dust removal mechanism 8 is provided at the lower end of the bearing seat 6. The dust removal mechanism 8 includes a connecting flange 9 fixedly connected to the lower end of the bearing seat 6. Several cantilever arms 10 are movably connected to the outside of the connecting flange 9. A dust removal pipe 11 is movably connected to the end of the cantilever arm 10 away from the connecting flange 9. A first wall cover 12 is fixedly connected to the bottom of the dust removal pipe 11. The dust removal pipe 11 communicates with the inner cavity of the first wall cover 12 and is fixedly connected to several sealing rings 13. A connecting pipe 14 is movably connected between two adjacent dust removal pipes 11, and a second wall cover 15 is fixedly connected to the bottom of the connecting pipe 14.

[0015] like Figures 2-3 As shown, several first C-shaped shaft brackets 16 are fixedly connected to the outside of the connecting flange 9 to provide an installation base for the first arm 17 in the cantilever 10. The base setting height of the entire dust removal mechanism 8 can be adjusted by adding connecting columns of different heights between the connecting flange 9 and the shaft seat 6.

[0016] like Figures 3-5As shown, the cantilever 10 includes a first arm body 17 and a second arm body 18. One end of the first arm body 17 is rotatably connected to one of the first C-shaped shaft brackets 16. Both ends of the second arm body 18 are fixedly connected to second C-shaped shaft brackets 19. The second arm body 18 is rotatably connected to one end of the first arm body 17 through one of the second C-shaped shaft brackets 19. After the first arm body 17 and the second arm body 18 are rotatably connected, the end of the first arm body 17 away from the second arm body 18 is rotatably connected to the first C-shaped shaft bracket 16, which allows for angle adjustment between the first arm body 17 and the second arm body 18. This allows for horizontal adjustment of the distance between one set of dust removal pipes 11, the first wall cover 12, and the connecting flange 9, thereby adjusting several... The diameter of the assembly formed by the dust removal pipe 11, the first wall-mounted cover 12, the connecting pipe 14, and the second wall-mounted cover 15 is adapted to fit mixing drums of different diameters. Several first suction ports 20 are provided on one side of the first wall-mounted cover 12 to suck up floating dust near the mixing drum opening into the dust removal pipe 11. A fixed base 21 is fixedly connected to the center of the upper end of the dust removal pipe 11. The fixed base 21 is rotatably connected to a second C-shaped shaft 19 at one end of one of the second arms 18. A dust removal pipe connector 22 is fixedly connected to one side of the dust removal pipe 11. The dust removal pipe connector 22 is connected to the input end of an external dust removal device via a pipeline. This allows for the use of several first wall-mounted covers 12 and second wall-mounted covers 15 arranged axially along the mixing drum opening, in conjunction with external dust removal equipment. The negative pressure suction of the dust collector removes the floating dust generated when pouring raw materials. A reinforcing steel sheet 23 is fixedly connected inside the sealing ring 13, and several internal threaded groove blocks 24 are fixedly connected to the outside of the reinforcing steel sheet 23. The outer surface of the sealing ring 13 is covered with sealing rubber. The internal threaded groove blocks 24 are threadedly connected to the dust collection pipe 11 with fixing screws. The sealing ring 13 with the internal reinforcing steel sheet 23 can improve the overall structural strength, thus making it easy to fix to the dust collection pipe 11 with screws. It provides sealing and damping functions for the connection of the dust collection pipe 11, the first wall cover 12, the connecting pipe 14, and the second wall cover 15. The inner cavity of the connecting pipe 14 and the second wall cover 15 are connected. The longitudinal cross-sectional dimensions of the connecting pipe 14 and the second wall cover 15 are small. The longitudinal cross-sectional dimensions of the dust removal pipe 11 and the first wall cover 12 are such that the ends of the connecting pipe 14 and the second wall cover 15 are respectively inserted into the sealing rings 13 inside one set of dust removal pipe 11 and the first wall cover 12. Several second dust suction ports 25 are opened on one side of the second wall cover 15. The combination of the connecting pipe 14 and the second wall cover 15 connects the cavities inside the two adjacent connecting pipes 14 and the second wall cover 15. The flexible connecting pipe 14 and the second wall cover 15 can adapt to the deformation according to the horizontal position adjustment of the dust removal pipe 11 and the first wall cover 12, ensuring the connectivity between the cavities inside the three sets of connecting pipes 14 and the second wall cover 15, thereby realizing the circumferential dust suction along the inside of the mixing barrel opening.

[0017] It should be noted that this utility model is a water-based coating mixing device. Before starting the device, the size of the dust removal mechanism 8 is adjusted according to the specifications of the mixing tank. By pushing and pulling two of the dust removal pipes 11 or the second arm 18, and by adjusting the angle between the first arm 17 and the second arm 18, the horizontal distance between the dust removal pipe 11, the first wall cover 12, and the connecting flange 9 is adjusted. At the same time, the two adjacent sets of dust removal pipes 11 and the first wall cover 12 drive the corresponding connecting pipes 14 and the second wall cover 15 to move synchronously, and make... The connecting pipe 14 and the second wall cover 15 are respectively inserted and moved in the sealing rings 13 in the corresponding dust removal pipe 11 and the first wall cover 12, and can be adapted to deform. This allows the combined diameter of several sets of dust removal pipes 11, the first wall cover 12, the connecting pipe 14, and the second wall cover 15 to be adjusted. The positioning of each component is achieved by using the friction between the connecting pipe 14, the second wall cover 15 and the sealing rings 13, as well as the friction between the first C-shaped shaft frame 16 and the first arm body 17, and between the first arm body 17 and the second C-shaped shaft frame 19. When the raw materials are mixed, the hydraulic station 2 drives the hydraulic lifting column 3 to adjust the height of the transmission box 4 so that the dispersing component at the lower end of the rotating shaft 7 extends into the appropriate position of the mixing tank. After the motor 5 starts, it drives the rotating shaft 7 to rotate at high speed through the belt. The rotating shaft 7 drives the dispersing component to rotate. Then, the water-based resin, deionized water and other base materials are stirred into a uniform liquid environment. When the barium sulfate, stone powder and other powder raw materials are poured, the negative pressure generated by the external dust removal equipment is transmitted to the first wall cover 12 and the second wall cover 15 through the dust removal pipe 11 and the connecting pipe 14. As a result, the floating dust will be quickly sucked in by the first dust suction port 20 and the second dust suction port 25 and transported to the external dust removal equipment through the dust removal pipe 11 and the connecting pipe 14 to prevent the dust from spreading.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
