Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion coating production technology, specifically to a raw material grinding device for anti-corrosion coating production. Background Technology

[0002] Anti-corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, and are an essential type of paint. Conventional anti-corrosion coatings provide corrosion protection for metals under normal conditions, extending the service life of non-ferrous metals. Heavy-duty anti-corrosion coatings, compared to conventional anti-corrosion coatings, can be used in relatively harsh corrosive environments and have a longer protection period. Anti-corrosion coating grinding equipment is a key piece of equipment used to finely disperse and uniformly grind solid particles in anti-corrosion coatings, playing a vital role in the production of anti-corrosion coatings.

[0003] Chinese Patent Publication No. CN215541444U discloses a grinding device for raw materials used in the production of anti-corrosion coatings, belonging to the field of coating processing technology. It includes a hydraulic cylinder, a loading hopper, and a feeding body. The loading hopper is movably connected to the left side of the hydraulic cylinder, and the feeding body is fixedly connected to the left side of the loading hopper. The hydraulic cylinder includes an electric motor, a rotating rod, a grinding body, and blades. The electric motor is fixedly connected to the upper left surface of the hydraulic cylinder, the rotating rod is movably connected to the bottom surface of the electric motor, the grinding body is fixedly connected to the bottom periphery of the rotating rod, and the blades are fixedly connected to the outer bottom periphery of the rotating rod. This design incorporates fan blades. The raw materials for anti-corrosion coating production poured into the feeding port and passing through the channel drive the fan blades to rotate, converting the kinetic energy of the fan blades into electrical energy to power the grinding body driven by the electric motor. This allows the device to generate and recycle electrical energy during operation, achieving an environmentally friendly and energy-saving effect for grinding raw materials used in the production of anti-corrosion coatings.

[0004] Since grinding devices generate heat when grinding raw materials for anti-corrosion coatings, the grinding structure of existing grinding devices is mostly located inside the device and needs to rotate at high speed, which makes heat dissipation difficult, causing overheating and affecting the stability of anti-corrosion components. Therefore, we propose a raw material grinding device for the production of anti-corrosion coatings. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 A raw material grinding device for producing anti-corrosion coatings includes a feeding cylinder 1, a lifting ring 19 installed inside the feeding cylinder 1, a second connecting bearing 18 installed inside the lifting ring 19, a grinding bucket 16 installed inside the second connecting bearing 18, a grinding block 14 installed inside the grinding bucket 16, a heat dissipation duct 15 opened inside the grinding block 14, a support plate 2 integrally fixedly installed below the grinding block 14, fan blades 4 and heat dissipation fins 13 installed on the outer surface of the grinding bucket 16, electric push rods 6 installed on both sides of the feeding cylinder 1, an upper feeding cylinder 8 installed above the electric push rods 6, a first connecting bearing 7 and a guide cylinder 9 installed inside the upper feeding cylinder 8, a grinding motor 10 installed on the side of the electric push rod 6 near the grinding bucket 16, a second pulley 11 installed at the output end of the grinding motor 10, a transmission belt 12 connected to the outer surface of the second pulley 11, a first pulley 5 installed on the left side of the transmission belt 12, a wind duct 3 installed above the feeding cylinder 1, and a connecting pipe 21 installed on one side of the wind duct 3.

[0027] In this implementation scheme: by setting fan blades 4 and heat sinks 13 on the outer surface of the grinding bucket 16, the high-speed rotating grinding bucket 16 drives the fan blades 4 to rotate, accelerating the flow of gas around the grinding bucket 16. The heat sinks 13 increase the heat dissipation area of ​​the grinding bucket 16. The two work together to dissipate heat for the grinding bucket 16, while avoiding overheating damage to the anti-corrosion coating. At the same time, a heat dissipation air duct 15 is set inside the grinding block 14, and the airflow generated by the fan blades 4 is guided into it to remove heat, thus solving the problem of heat dissipation difficulty of the high-speed rotating grinding bucket 16 and avoiding heat accumulation damage to the grinding bucket 16.

[0028] Furthermore:

[0029] In an optional embodiment, the grinding bucket 16 has a funnel-shaped structure. The grinding bucket 16 is movably connected to the feeding cylinder 8 through the first connecting bearing 7. The guide cylinder 9 is connected to the grinding bucket 16. The grinding bucket 16 is connected to the feeding cylinder 1. The grinding bucket 16 is movably connected to the lifting ring 19 through the second connecting bearing 18.

[0030] In this implementation plan: when the anti-corrosion coating raw material is poured into the feeding cylinder 8, the anti-corrosion coating raw material can enter the grinding hopper 16 along the guide cylinder 9 for grinding, and after grinding, it can enter the discharge cylinder 1 for discharge.

[0031] Furthermore:

[0032] In an optional embodiment, the first pulley 5 is fixedly connected to the grinding bucket 16, and the grinding bucket 16 is belt driven to the grinding motor 10 through the first pulley 5, the transmission belt 12, and the second pulley 11.

[0033] In this implementation plan: when the grinding motor 10 is working, it can drive the grinding bucket 16 to rotate and cooperate with the grinding block 14 to carry out the grinding work.

[0034] Furthermore:

[0035] In an optional embodiment, the fan blades 4 are uniformly distributed along the outer surface of the grinding hopper 16, and the heat sink 13 is uniformly distributed along the outer surface of the grinding hopper 16.

[0036] In this implementation scheme: when the grinding hopper 16 rotates, it drives the fan blades 4 to rotate, which can accelerate the flow of gas around the grinding hopper 16. The heat sink 13 increases the heat dissipation area of ​​the grinding hopper 16, so the flowing gas can quickly remove the heat on the grinding hopper 16.

[0037] Furthermore:

[0038] In an optional embodiment, the upper part of the grinding block 14 is conical and the lower part is cylindrical. The shape and size of the grinding block 14 are smaller than the shape and size inside the grinding bucket 16. The support plate 2 is fixedly connected to the feeding cylinder 1. The heat dissipation duct 15 passes through the support plate 2 and the interior of the grinding block 14 in sequence. The heat dissipation duct 15 is connected to the air duct 3 through the connecting pipe 21.

[0039] In this implementation scheme: when the gas flows through the heat dissipation duct 15, it can carry away the heat on the grinding block 14.

[0040] Furthermore:

[0041] In an optional embodiment, the feed cylinder 1 is further provided with:

[0042] The limiting slide 20 is formed on both sides of the inner wall of the feeding cylinder 1. The limiting slide 17 is movably installed inside the limiting slide 20. The shape and size of the limiting slide 17 partially match the shape and size inside the limiting slide 20. The limiting slide 17 is fixedly connected to the lifting ring 19. The lifting ring 19 moves inside the feeding cylinder 1 through the limiting slide 17 and the limiting slide 20.

[0043] In this implementation scheme: when the electric push rod 6 is working, it can push the lifting ring 19 to move inside the feed cylinder 1, thereby adjusting the grinding gap between the grinding block 14 and the grinding bucket 16.

[0044] Furthermore:

[0045] In an optional embodiment, the ventilation duct 3 is further provided with:

[0046] Air outlet 22 is located on the inner wall of air duct 3.

[0047] In this implementation scheme: part of the airflow generated by the rotation of the fan blades 4 enters the heat dissipation duct 15 through the connecting pipe 21, and the rest flows out through the air outlet 22.

[0048] Working principle: When using this raw material grinding device for anti-corrosion coating production, the controller first controls the electric push rod 6 to move the grinding bucket 16 up or down inside the feeding cylinder 1, thereby adjusting the distance between the grinding block 14 and the grinding bucket 16 to grind the anti-corrosion coating to a specific size. Then, the cylinder cover above the feeding cylinder 8 is opened to pour the anti-corrosion coating raw material to be ground into the feeding cylinder 8. The anti-corrosion coating raw material will enter the grinding bucket 16 along the guide cylinder 9. Next, the controller controls the grinding motor 10 to be powered on, and the grinding motor 10 drives the grinding through the second pulley 11, the transmission belt 12 and the first pulley 5. The grinding bucket 16 rotates at high speed. The rotating grinding bucket 16 and the grinding block 14 work together to grind the anti-corrosion coating raw material. The ground anti-corrosion coating raw material falls into the feed cylinder 1 and is then discharged. Next, the rotating grinding bucket 16 drives the fan blades 4 and the heat sink 13 to rotate. The rotating fan blades 4 drive the flow of air around the grinding bucket 16. The flowing air will carry away the heat on the grinding bucket 16 and the heat sink 13. At the same time, these airflows are guided into the heat dissipation air duct 15 by the air duct 3 and the connecting pipe 21, and carry away the heat generated by the grinding block 14 during grinding. The excess gas is discharged from the air outlet 22. This is the working principle of the raw material grinding device for anti-corrosion coating production.
