Description

Technical Field

[0001] This utility model belongs to the field of ball mill technology, and in particular relates to a ball mill for the production of intumescent fireproof coatings. Background Technology

[0002] Intumescent fire retardant coatings are single-component self-drying coatings composed of ethyl fiber, chlorinated paraffin, fire retardant pigments, additives, solvents, etc. They have advantages such as good protective performance, fast drying, high hardness, strong adhesion, good mechanical properties, good compatibility with substrates, and superior fire resistance.

[0003] During the grinding process in a ball mill, the steel balls, being round, may not effectively cover all areas on both sides of the drum, resulting in dead corners. The material in these dead corner areas receives less grinding and mixing, which may affect the fineness and uniformity of the material, thus affecting product quality. To address this, we provide a ball mill for the production of intumescent fire-retardant coatings. Utility Model Content

[0004] The purpose of this utility model is to provide a ball mill for the production of intumescent fireproof coatings. During the process of the ball mill barrel being driven by motor one, gear one will rotate on the surface of gear two, thereby driving the stirring blocks on both sides of the barrel to rotate. This solves the problem that when the ball mill is grinding, the steel balls, being round, may not be able to effectively cover all areas on both sides of the barrel, resulting in dead corners and less grinding and mixing of the material in these dead corner areas.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a ball mill for producing intumescent fireproof coatings, including a motor, a grinding mechanism on the outer wall of the motor, and a screening mechanism at the bottom of the motor.

[0007] The grinding mechanism includes a bracket, the outer wall of which is fixedly connected to the inner wall of a motor. The bottom output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A gear is rotatably connected to the outer surface of the rotating shaft. A grinding barrel is fixedly connected to the outer wall of the rotating shaft. A baffle is slidably connected to the inner wall of the grinding barrel. A bolt is threaded inside the baffle. A rotating shaft is rotatably connected to the inner wall of the grinding barrel. A gear is fixedly connected to the outer surface of the rotating shaft. A stirring block is fixedly connected to the end of the outer surface of the rotating shaft away from the gear. A locking block is fixedly connected to the inner wall of the grinding barrel. A steel ball is slidably connected to the inner wall of the grinding barrel.

[0008] Furthermore, there are two rotating shafts in total, the outer wall of the second gear is fixedly connected to the inner wall of the bracket, and the outer surface of the bolt is threadedly connected to the inside of the ball mill barrel.

[0009] Furthermore, the screening mechanism includes a fixed frame, the inner wall of which is fixedly connected to the outer wall of the fixed frame.

[0010] Furthermore, a second motor is fixedly connected to the top of the fixed frame, and a second rotating shaft is fixedly connected to the bottom output shaft of the second motor via a coupling. An eccentric wheel is fixedly connected to the outer surface of the second rotating shaft.

[0011] Furthermore, a telescopic rod is fixedly connected to the inner wall of the fixed frame, and a telescopic spring is sleeved on the outer surface of the telescopic rod.

[0012] Furthermore, a filter plate is fixedly connected to the end of the outer wall of the telescopic rod away from the fixed frame, and a sliding groove is provided on the inner wall of the bracket, and the inner wall of the sliding groove is slidably connected to the outer surface of the filter plate.

[0013] Furthermore, the end of the outer wall of the telescopic spring away from the fixed frame is fixedly connected to the outer wall of the filter plate, and a guide plate is fixedly connected to the inner wall of the bracket.

[0014] Furthermore, the outer surface of the filter plate is slidably connected to the inner wall of the guide plate, a collection box is fixedly connected to the bottom of the guide plate, and a drawer is slidably connected to the inner wall of the collection box.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a stirring block, allows for the following process during grinding: Motor 1 is started, driving a rotating shaft to rotate, which in turn rotates the ball mill barrel. Gears 1 on both sides rub against and rotate on the surfaces of gears 2 on both sides. Gear 1 then drives the rotating shaft 1 on the inner wall to rotate, which in turn drives the stirring blocks on both sides of the ball mill barrel to rotate, stirring the coating material on both sides. Simultaneously, the rotation of the ball mill barrel causes the coating material and steel balls inside to rotate and rub against each other. The locking block assists the steel balls in better contacting and rubbing with the coating material, effectively promoting uniform mixing and dispersion of the material, preventing coating component deposition and uneven distribution, thereby enhancing the ball milling effect and ensuring the consistency and stability of the coating quality.

[0017] 2. This utility model, by setting an eccentric wheel, allows the polished paint to fall onto the surface of the guide plate, which then directs the paint onto the surface of the filter plate. At this point, motor two is activated, driving rotating shaft two to rotate. Rotating shaft two then drives the eccentric wheel. When the longer end of the eccentric wheel contacts the filter plate, the filter plate is compressed, and the telescopic spring extends. The telescopic rod provides a limiting position, and the filter plate slides in the sliding groove. When the eccentric wheel stops compressing, the telescopic spring causes the filter plate to retract and reset. This process repeats, causing the filter plate to continuously vibrate, thus thoroughly sieving the paint. The reciprocating vibration of the filter plate effectively sieves the paint, removes impurities, ensures uniform paint quality, improves production efficiency, and facilitates maintenance.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a ball mill for producing intumescent fireproof coatings, including a motor 101, a grinding mechanism 1 on the outer wall of the motor 101, and a screening mechanism 2 at the bottom of the motor 101.

[0029] The grinding mechanism 1 includes a bracket 102, the outer wall of which is fixedly connected to the inner wall of a motor 101. A rotating shaft 109 is fixedly connected to the bottom output shaft of the motor 101 via a coupling. The motor 101 drives the rotating shaft 109 to rotate, which in turn drives the grinding drum 103 to rotate. The grinding drum 103 then drives the rotating shaft 106 to rotate circumferentially. At this time, gear 105 rotates on the surface of gear 108, thereby driving the rotating shaft 106 to rotate. Subsequently, the stirring block 107 rotates inside the grinding drum 103, thereby increasing contact efficiency, enhancing the grinding effect, accelerating the crushing and refining of the abrasive, and improving production efficiency. Gear 108 is rotatably connected to the outer surface of the rotating shaft 109, and the grinding drum 103 is fixedly connected to the outer wall of the rotating shaft 109. A baffle 104 is slidably connected to the inner wall of the grinding drum 103. By rotating the bolt 112 at the top of the baffle 104, the baffle 104 can be rotated. 4. The baffle 104 is internally threaded with bolts 112. A rotating shaft 106 is rotatably connected to the inner wall of the ball mill 103. A gear 105 is fixedly connected to the outer surface of the rotating shaft 106. An agitator 107 is fixedly connected to the end of the outer surface of the rotating shaft 106 away from the gear 105. A locking block 110 is fixedly connected to the inner wall of the ball mill 103. The locking block 110 allows the steel balls 111 to move inside the ball mill 103 in contact with the coating material. More collisions and friction occur, ensuring that the material is ground more thoroughly, thereby improving the ball mill efficiency. The inner wall of the ball mill barrel 103 is slidably connected with steel balls 111. There are two rotating shafts 109. The outer wall of gear 2 108 is fixedly connected to the inner wall of the bracket 102 with bolts 112 and the outer surface of the bolts 112 are threadedly connected to the inside of the ball mill barrel 103. Gear 1 105 meshes with gear 2 108. The screening mechanism 2 includes a fixed frame 201, and the inner wall of the fixed frame 201 is fixedly connected to the outer wall of the fixed frame 201.

[0030] A motor 202 is fixedly connected to the top of the fixed frame 201. The motor 202 drives the rotating shaft 208 to rotate, which in turn drives the eccentric wheel 209 to rotate. At this time, the eccentric wheel 209 will make a circular motion, causing its longer end to press against the filter plate 206, making it slide. The bottom output shaft of the motor 202 is fixedly connected to the rotating shaft 208 via a coupling. The eccentric wheel 209 is fixedly connected to the outer surface of the rotating shaft 208. The inner wall of the fixed frame 201 is fixedly connected to... A telescopic rod 210 is attached, and a telescopic spring 211 is fitted on the outer surface of the telescopic rod 210. The telescopic spring 211 can drive the filter plate 206 to retract and reset when the eccentric wheel 209 is not pressing the filter plate 206, thereby making the filter plate 206 continuously shake and fully screen the material, thus ensuring that the coating particles are uniform and fine, which helps to improve the adhesion and uniformity of the coating and enhance the fireproof effect. The filter plate 206 is fixedly connected to the end of the outer wall of the telescopic rod 210 away from the fixed frame 201.

[0031] The inner wall of the support 102 is provided with a sliding groove 207, which can limit the filter plate 206 to move horizontally in a straight line. The inner wall of the sliding groove 207 is slidably connected to the outer surface of the filter plate 206. The end of the outer wall of the telescopic spring 211 away from the fixed frame 201 is fixedly connected to the outer wall of the filter plate 206. A guide plate 203 is fixedly connected to the inner wall of the support 102. The guide plate 203 can limit the paint flowing out of the ball mill barrel 103, so that it falls accurately onto the surface of the filter plate 206 for screening. The outer surface of the filter plate 206 is slidably connected to the inner wall of the guide plate 203. A collection box 204 is fixedly connected to the bottom of the guide plate 203. The collection box 204 can collect the screened paint in a concentrated manner for convenient subsequent processing. A drawer 205 is slidably connected to the inner wall of the collection box 204.

[0032] One specific application of this embodiment is:

[0033] Before grinding, loosen bolt 112, remove baffle 104 from inside the grinding barrel 103, open the gap, and pour in the coating. When grinding, close baffle 104 and tighten bolt 112. Then, start motor 101. Motor 101 will drive rotating shaft 109 to rotate, which in turn drives grinding barrel 103 to rotate. Grinding barrel 103 will then drive rotating shafts 106 on both sides to rotate in a circular motion. At this time, gears 105 on both sides will rub against the surfaces of gears 108 on both sides and rotate. Then, gear 105 will drive the inner wall rotating shaft 106 to rotate. Then, the two rotating shafts 106 will drive the surface stirring blocks 107 to rotate on both sides of the ball mill barrel 103, and stir the coating on both sides. While the ball mill barrel 103 is rotating, it will drive the coating and steel balls 111 inside to rotate and rub against each other. The locking block 110 is responsible for assisting the steel balls 111 to better contact and rub against the coating. After grinding, the baffle 104 can be aligned with the center point of the two guide plates 203, and then the bolt 112 can be turned to pull out the baffle 104.

[0034] When the polished paint falls onto the surface of the guide plate 203, the guide plate 203 will deliver the paint to the surface of the filter plate 206. At this time, the motor 202 can be started, which will drive the rotating shaft 208 to rotate. The rotating shaft 208 will then drive the eccentric wheel 209, which will rotate in a regular circular motion. When the longer end of the eccentric wheel 209 contacts the filter plate 206, the filter plate 206 will be compressed. At the same time, the telescopic spring 211 will extend, and the telescopic rod 210 will limit the movement. The filter plate 206 will then slide in the sliding groove 207. When the eccentric wheel 209 stops compressing, the telescopic spring 211 will cause the filter plate 206 to retract and return to its original position. This process is repeated, causing the filter plate 206 to shake continuously, thereby fully sieving the paint. The sieved paint will then fall into the drawer 205. When it needs to be removed, the drawer 205 can be pulled out from the collection box 204 to complete the collection.
