Description

Technical Field

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

[0002] In modern industrial production, welds are crucial connections between various metal structural components, making corrosion protection paramount. High-quality weld seam anti-corrosion coatings effectively prevent weld seams from being corroded by corrosive media, extending the service life of metal structures and ensuring the safe and stable operation of industrial facilities. With rapid industrial development, the performance requirements for weld seam anti-corrosion coatings are becoming increasingly stringent. They not only need excellent corrosion resistance but also good adhesion, uniformity, and ease of application. This has led to a continuous increase in the demand for high-quality weld seam anti-corrosion coatings.

[0003] Traditional production processes for weld seam anti-corrosion coating materials have several shortcomings. In the drying stage, a simple hot air drying method is often used, placing the material in a fixed drying chamber for heating. This method is not only inefficient and difficult to implement for continuous production, but also prone to uneven heating, leading to over-drying and deterioration of some materials, while under-drying leaves residual moisture that affects subsequent processing and product quality. In the grinding stage, traditional grinding equipment is often single-function, either only capable of crushing or with poor grinding effects. Some grinding equipment cannot precisely control the powder particle size during grinding, resulting in uneven particle size distribution, failing to meet the stringent particle size consistency requirements of weld seam anti-corrosion coatings. Furthermore, the screening mechanisms of traditional equipment are inadequate, failing to efficiently separate qualified particles from unqualified ones. A large number of unqualified particles are mixed into the finished product, reducing product quality and increasing subsequent rework costs. Utility Model Content

[0005] This utility model provides a production device for weld anti-corrosion coating materials to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a production device for weld anti-corrosion coating materials, including a frame, on which a dryer and a grinding mechanism are arranged. The dryer includes a screw feeder, and a heating component is arranged on the outside of the screw feeder. The screw feeder is used to convey coating materials, and the heating component is used to dry the coating materials during the conveying process. The feed inlet of the grinding mechanism is opposite to the output outlet of the grinding mechanism.

[0008] Preferably, a feed inlet is provided at one end of the screw feeder, and a discharge outlet is provided at one end of the other end of the screw feeder. The input shaft of the screw feeder is connected to a reducer, and the reducer is connected to a motor.

[0009] Preferably, the screw feeder is fixed above the frame by a pair of support frames. The heating assembly includes several heaters evenly spaced on the outside of the screw feeder and baffles fixed on the support frames. A protective shell is provided between the two baffles. An insulation sleeve is provided on the inner wall of the protective shell, and the heaters are located inside the insulation sleeve.

[0010] Preferably, the grinding mechanism includes a grinding chamber fixed on the frame, a rotating shaft rotatably installed inside the grinding chamber, one end of the rotating shaft extending out of the grinding chamber and connected to the drive mechanism, an arc-shaped filter plate at the bottom of the grinding chamber, a receiving chamber below the filter plate, a plurality of crushing teeth on the rotating shaft, and a grinding plate at the end of the crushing teeth.

[0012] 3. Beneficial effects:

[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0014] The combined design of the screw feeder and heater in this invention allows the coating material to be continuously dried during the conveying process, enabling continuous production and improving production efficiency. The insulation sleeve, protective shell, and baffles on the outside of the heater form a good insulation structure, reducing heat loss, lowering energy consumption, and saving production costs. This invention can remove moisture from the coating material, preventing moisture from affecting the subsequent grinding effect and the quality and performance of the final product, such as avoiding problems like deterioration and clumping of the coating material during storage or use due to moisture.

[0015] In this invention, the crushing teeth on the rotating shaft of the grinding mechanism cooperate with the grinding plate to both crush and grind the material, adapting to coating materials of different hardness and properties, thus improving the applicability of the grinding process. The arc-shaped filter plate effectively screens out powder that meets the particle size requirements, ensuring the consistency and stability of the product particle size and improving product quality. This invention pulverizes the dried coating material into powder to meet the specific particle size requirements of weld anti-corrosion coating materials, ensuring uniform coverage of the weld surface during coating and improving the anti-corrosion effect. The motor drives the rotating shaft to rotate via belt drive, resulting in a simple structure, smooth transmission, and easy maintenance and operation. Attached Figure Description

[0029] See attached document Figures 1-6 A production device for anti-corrosion coating material for weld seams includes a frame 1, on which a dryer 2 and a grinding mechanism 3 are mounted. The dryer 2 includes a screw feeder 21, and a heating component is mounted on the outside of the screw feeder 21. The screw feeder 21 is used to convey coating material, and the heating component is used to dry the coating material during the conveying process. The feed inlet of the grinding mechanism 3 is opposite to the output outlet of the grinding mechanism 3.

[0030] The screw feeder 21 has a feed inlet 23 at one end and a discharge outlet 24 at the other end. The input shaft of the screw feeder 21 is connected to the reducer 4, and the reducer 4 is connected to the motor 5.

[0031] The screw feeder 21 is fixed above the frame 1 by a pair of support frames 22. The heating component includes several heaters 28 that are equally spaced on the outside of the screw feeder 21 and baffles 26 fixed on the support frames 22. A protective shell 25 is provided between the two baffles. An insulation sleeve 27 is provided on the inner wall of the protective shell 25. The heaters 28 are located inside the insulation sleeve 27.

[0032] The grinding mechanism 3 includes a grinding chamber 31 fixed to the frame 1. A rotating shaft 32 is rotatably mounted inside the grinding chamber 31. One end of the rotating shaft 32 extends out of the grinding chamber 31 and is connected to the drive mechanism 33. An arc-shaped filter plate 34 is provided at the bottom of the grinding chamber 31, and a receiving chamber 35 is provided below the filter plate 34. Several crushing teeth 36 are provided on the rotating shaft 32, and grinding plates 37 are provided at the ends of the crushing teeth 36. The discharge port 24 is located above the grinding chamber 31. The grinding plates 37 are fixed to the ends of the crushing teeth 36 on the rotating shaft 32 and rotate at high speed as the rotating shaft 32 rotates. Its surface has a certain roughness and a specific texture design, which provides the necessary friction conditions for grinding. After the dried coating material enters the grinding chamber 31, the crushing teeth 36 on the rotating shaft 32 first perform preliminary crushing on it. As the rotating shaft 32 rotates, the crushed material moves towards the bottom of the grinding chamber 31 under the combined action of centrifugal force and gravity. During this process, the grinding plate 37 begins to contact larger particles of material. The high-speed rotation of the grinding plate 37 continuously pushes the material towards the filter plate 34, where it undergoes initial grinding. Some larger particles are ground into smaller particles and begin to slide down the curved surface of the filter plate 34. As the material slides down the filter plate 34, it is subjected to shearing and friction between the grinding plate 37 and the filter plate 34 due to the continuous rotation of the grinding plate 37. After multiple grinding processes, the smaller particles gradually decrease in size. When they reach the required sieve aperture size of the filter plate 34, they pass through the sieve aperture and fall into the receiving bin 35 below. Larger particles that have not yet reached the required size continue to circulate and grind between the surface of the filter plate 34 and the grinding plate 37 until their particle size meets the requirement to pass through the sieve aperture. Throughout the process, the filter plate 34 not only screens qualified powder, but its curved surface also guides the flow path of the material, allowing the material to make more thorough contact with the grinding plate 37, achieving an efficient and continuous grinding process.

[0033] The drive mechanism 33 includes a pulley 331 fixed on a rotating shaft 32, a motor 334 fixedly mounted on the frame 1, a pulley 333 fixedly mounted on the motor 334, and the pulley 331 and the pulley 333 are connected by a belt 332.

[0034] Working principle

[0035] Raw material feeding: The coating material, in its raw state (e.g., in block or granular form mixed with a certain amount of moisture), is precisely poured in from the feed inlet 23 above one end of the screw feeder 21, either manually or with the aid of feeding equipment. Immediately afterwards, motor 25 is powered on and starts, transmitting its high-speed rotational power to reducer 4. Reducer 4 reduces the motor's high speed while increasing torque, which is then output to the input shaft of the screw feeder 21. The spiral blades inside the screw feeder 21 begin to rotate, acting like an orderly conveyor belt, slowly pushing the incoming coating material forward along the feeder's pipe.

[0036] Heating and drying operation: While the screw feeder 21 conveys the material, multiple heaters 28 installed on its outer side are simultaneously turned on. These heaters 28 are evenly distributed throughout the circumference of the screw feeder, enabling uniform heating of the material inside the screw feeder 21. Since the heaters 28 are enclosed in a closed space constructed by the insulation sleeve 27, protective shell 25, and baffle 26, heat is effectively confined to this area, greatly reducing heat loss to the surrounding environment. As the material moves within the screw feeder, it comes into full contact with the heat flow, and the moisture gradually evaporates, achieving a continuous operation mode of conveying and drying simultaneously. After a period of conveying and drying, the moisture content in the coating material is significantly reduced, reaching the predetermined drying standard. At this point, the material is pushed by the screw feeder 21 to the discharge port 24 and discharged from the discharge port, completing the drying stage and entering the next process—the grinding stage.

[0037] Grinding Power Transmission: The dried coating material discharged from the dryer's discharge port 24 falls directly into the grinding chamber 31 below under gravity. The top opening design of the grinding chamber 31 accurately receives the dried material, ensuring that no material is missed and preparing it for subsequent grinding operations. Motor 1 334 starts operating, and the motor shaft drives pulley 2 333, which is fixed to it, to rotate at high speed. Pulley 2 333 is in close contact with belt 332, and friction drives the belt to move. The other end of the belt is connected to pulley 1 331, which in turn drives pulley 1 331, which is fixed to the rotating shaft 32, to rotate, transmitting the motor's power to the rotating shaft 32, causing the rotating shaft 32 to rotate at high speed within the grinding chamber 31.

[0038] Crushing and Grinding Process: As the rotating shaft 32 rotates, the crushing teeth 36 fixed on its surface also rotate at high speed. When the dried coating material enters the grinding chamber 31, the crushing teeth 36, like sharp knives, perform initial impact and crushing on the material, breaking larger pieces into smaller ones. Simultaneously, the grinding plates 37 installed at the ends of the crushing teeth 36 also begin to function. The grinding plates 37 have a certain roughness and special texture, and as the crushing teeth 36 rotate, they further grind the already crushed small pieces of material. The material is continuously squeezed, rubbed, and kneaded between the grinding plates 37, the inner wall of the grinding chamber 31, and other materials, causing the particle size to gradually decrease.

[0039] Screening and Collection of Finished Product: Under the influence of gravity, the crushed and ground material continuously falls downwards. An arc-shaped filter plate 34 is installed at the bottom of the grinding chamber 31, with evenly distributed sieve holes of a specific size. When the ground material comes into contact with the filter plate 34, powder that meets the particle size requirements can pass smoothly through the sieve holes and fall into the receiving chamber 35 below. Particles that are too large and do not meet the requirements will continue to be ground by the grinding plate 37 on the surface of the filter plate 34 until their particle size is reduced to be able to pass through the sieve holes. The receiving chamber 35 is used to collect the qualified powder that has passed through the filter plate 34, thus completing the entire grinding process and producing a powdered material that meets the requirements for weld anti-corrosion coating.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
