Description

Technical Field

[0001] This utility model relates to the field of RD01 ultrafine calcium powder production technology, specifically to an ultrafine calcium powder grinding mill. Background Technology

[0002] The calcium powder ultrafine grinding mill is a key piece of equipment specifically designed to process calcium raw materials such as calcium carbonate into ultrafine powder. It is widely used in industries such as plastics, rubber, coatings, papermaking, and pharmaceuticals. In the research and application of environmentally friendly coatings, RD01 ultrafine calcium powder is one of the important pieces of equipment for environmentally friendly coatings.

[0003] In the prior art, patent CN219232499U discloses a calcium powder ultrafine grinding mill, including a housing and a drive assembly; the upper surface of the housing is provided with a feeding port, and a feeding plate is rotatably mounted on the feeding port via a pin; both sides of the interior of the housing are equipped with fixing blocks, and a first inclined surface is provided on the fixing block, on which multiple blades are evenly mounted;

[0004] This type of calcium powder ultrafine grinding mill has some problems. For example, during the production process of RD01 ultrafine calcium powder, the ultrafine calcium powder is adsorbed onto the inner walls of the working chamber and grinding chamber under the action of static electricity, resulting in RD01 ultrafine calcium powder residue on the inner walls of the working chamber and grinding chamber, which affects the output efficiency of RD01 ultrafine calcium powder grinding. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a calcium powder ultrafine grinding mill, comprising a working chamber, a grinding chamber fixedly connected inside the working chamber, a drive chamber provided at the front end of the working chamber, and a striking mechanism;

[0007] The striking mechanism includes a sliding frame, a sliding groove, a rotating handle, a rotating shaft, striking handles, and a guide rod. The rotating shafts are rotatably connected to the left and right ends inside the working chamber.

The front ends of each rotating handle are fixedly connected to a connecting shaft. A guide rod is fixedly connected inside the grinding chamber, and the outer surface of the guide rod is slidably connected to the rear end of the sliding frame. Sliding grooves are provided at both ends of the sliding frame, and the interior of each sliding groove is slidably connected to the longitudinally adjacent connecting shaft. This mechanism enables intermittent striking between the working chamber and the grinding chamber during the grinding process, causing the working chamber and the grinding chamber to vibrate and preventing RD ultrafine calcium powder from adsorbing onto the inner walls of the working chamber and the grinding chamber.

[0008] Furthermore, the striking mechanism also includes a drive handle and a connecting rod. The lower end of the connecting rod is rotatably connected to the front end of the sliding frame via a pin. The upper end of the inner wall of the front side of the drive chamber is rotatably connected to a drive shaft. The rear end of the drive shaft is fixedly connected to a drive handle. The end of the drive handle away from the central axis of the drive shaft and the end of the connecting rod away from the central axis of the first pin are rotatably connected via a second pin, so as to realize the periodic rotation of the two rotating shafts, thereby realizing the intermittent striking of the working chamber and the grinding chamber.

[0009] Furthermore, a control switch group is provided at the front end of the left side surface of the work chamber. The input end of the control switch group is electrically connected to an external power supply to control the operation of various electrical appliances.

[0010] Furthermore, the striking mechanism also includes a motor, which is located at the front end of the drive chamber. The rear end of the output shaft of the motor is fixedly connected to the front end of the drive shaft, and the input end of the motor is electrically connected to the output end of the control switch group to provide driving force for the intermittent striking of the working chamber and the grinding chamber.

[0011] Furthermore, the grinding chamber has turntables rotatably connected to both the front and rear ends, and a rotating shaft is fixedly connected between the two turntables. The rear end of the rotating shaft extends to the rear side of the working chamber. Rotating shafts are rotatably connected to both the left and right ends between the two turntables. Grinding rollers are fixedly connected to the middle of the rotating shafts and the rotating shafts. The rear ends of the two rotating shafts extend to the rear side of the turntables. Gears are fixedly connected to the rear ends of the two rotating shafts. A fixed cylinder is fixedly connected to the middle of the inner wall of the rear side of the working chamber. An external gear ring is fixedly connected to the front end of the outer surface of the fixed cylinder. Both gears mesh with the external gear ring. Crossbars are fixedly connected to both the upper and lower ends between the two turntables. Scrapers are fixedly connected to the middle of the crossbars, thereby realizing the grinding of RD ultrafine calcium powder raw materials.

[0012] Furthermore, a second motor is provided at the rear end of the left side surface of the working chamber. A drive pulley is fixedly connected to the rear end of the output shaft of the second motor, and a driven pulley is fixedly connected to the rear end of the rotating shaft. The drive pulley and the driven pulley are connected by a transmission belt. The input end of the second motor is electrically connected to the output end of the control switch group to provide driving force for grinding the RD ultrafine calcium powder raw material.

[0013] Furthermore, the lower end of the grinding chamber is provided with uniformly distributed through holes, the upper end of the grinding chamber and the upper end of the working chamber are connected by a feed hopper, and the lower end of the working chamber is provided with a discharge hopper, providing a channel for the movement of RD ultrafine calcium powder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This calcium powder ultrafine grinding mill has the following advantages:

[0015] The vertical periodic movement of the sliding frame is achieved by a crank-connecting rod mechanism driven by a motor, which in turn causes the two rotating handles to rotate periodically. Finally, the periodically rotating striking handles intermittently strike the working chamber and the grinding chamber, causing them to vibrate. This prevents RD01 ultrafine calcium powder from adsorbing onto the inner walls of the working chamber and the grinding chamber, thus ensuring the discharge efficiency of the RD01 ultrafine calcium powder during fine grinding.

[0023] 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.

[0024] Please see Figure 1-6 This embodiment provides a technical solution: a calcium powder ultrafine grinding mill, including a working chamber 1, a grinding chamber 2 fixedly connected inside the working chamber 1, a drive chamber 3 provided at the front end of the working chamber 1, a control switch group 14 provided at the front end of the left side surface of the working chamber 1, the input end of the control switch group 14 being electrically connected to an external power supply, and also including a striking mechanism 4.

[0025] The striking mechanism 4 includes a sliding frame 44, a slide groove 45, a rotating handle 46, a rotating shaft 47, a striking handle 48, and a guide rod 49. The rotating shaft 47 is rotatably connected to the left and right ends inside the working chamber 1. The middle of each rotating shaft 47 is fixedly connected to evenly distributed striking handles 48. The striking handles 48 are fitted with the outer arc surface of the grinding chamber 2. The front ends of both rotating shafts 47 extend into the interior of the drive chamber 3. The front ends of each rotating shaft 47 are fixedly connected to a rotating handle 46. The front ends of each rotating handle 46 are fixedly connected to a connecting shaft. The interior of the grinding chamber 2 is fixedly connected to a guide rod 49. The outer surface of the guide rod 49 is slidably connected to the rear end of the sliding frame 44. The left and right ends of the sliding frame 44 are provided with slide grooves 45. The interior of each slide groove 45 is slidably connected to the longitudinally adjacent connecting shaft. Next, the striking mechanism 4 also includes a drive handle 42 and a connecting rod 43. The lower end of the connecting rod 43 is rotatably connected to the front end of the sliding frame 44 via a first pin. A drive shaft is rotatably connected to the upper end of the front inner wall of the drive chamber 3. The rear end of the drive shaft is fixedly connected to the drive handle 42. The end of the drive handle 42 away from the central axis of the drive shaft and the end of the connecting rod 43 away from the central axis of the first pin are rotatably connected via a second pin. The striking mechanism 4 also includes a first motor 41. The first motor 41 is located at the front end of the drive chamber 3. The rear end of the output shaft of the first motor 41 is fixedly connected to the front end of the drive shaft. The input end of the first motor 41 is electrically connected to the output end of the control switch group 14. The control switch group 14 realizes the operation of the first motor 41. The rotation of the output shaft of the first motor 41 drives the drive shaft to rotate, and the rotation of the drive shaft drives the... The drive handle 42 rotates, and this rotation drives the upper end of the connecting rod 43 to rotate around the central axis of the drive shaft via the second pin. When the drive handle 42 rotates upward, it pulls the upper end of the connecting rod 43 upward via the second pin, which in turn causes the lower end of the connecting rod 43 to pull the sliding frame 44 upward under the guidance of the guide rod 49 via the first pin. When the drive handle 42 rotates downward, it drives the upper end of the connecting rod 43 downward via the second pin, which in turn causes the lower end of the connecting rod 43 to push the sliding frame 44 downward under the guidance of the guide rod 49 via the first pin. As the drive handle 42 rotates in a circular motion, the sliding frame 44 moves vertically periodically. When the sliding frame 44 moves downward, the connecting shaft drives the corresponding sliding groove 45 to slide inside. Simultaneously, the sliding frame 44 moves downward, pushing the two rotating handles 46 to rotate closer to the center of the working chamber 1. This causes the two rotating shafts 47 to rotate closer to the center of the working chamber 1, ultimately causing the evenly distributed striking handles 48 to rotate closer to the center of the working chamber 1. The upper ends of the striking handles 48 strike the outer wall of the grinding chamber 2, and the lower ends of the striking handles 48 strike the inner wall of the working chamber 1. When the sliding frame 44 moves upward, the connecting shafts drive the corresponding sliding grooves 45 to slide internally. At the same time, the upward movement of the sliding frame 44 pulls the two rotating handles 46 to rotate away from the center of the working chamber 1, causing the two rotating shafts 47 to rotate away from the center of the working chamber 1. Ultimately, this causes the evenly distributed striking handles 48 to rotate away from the center of the working chamber 1.The upper end of the striking handle 48 strikes the inner wall of the working chamber 1, and the lower end of the striking handle 48 strikes the outer wall of the grinding chamber 2. As the sliding frame 44 moves vertically and periodically, the striking handle 48 intermittently strikes the working chamber 1 and the grinding chamber 2, preventing RD01 ultrafine calcium powder from remaining on the inner walls of the working chamber 1 and the grinding chamber 2 due to static electricity.

[0026] The grinding chamber 2 is rotatably connected to both its front and rear ends with turntables 5. A rotating shaft 6 is fixedly connected between the two turntables 5. The rear end of the rotating shaft 6 extends to the rear side of the working chamber 1. Rotating shafts are rotatably connected to both the left and right ends of the two turntables 5. Grinding rollers 7 are fixedly connected to the middle of both rotating shafts and rotating shaft 6. The rear ends of both rotating shafts extend to the rear side of the rear turntable 5. Gears 9 are fixedly connected to the rear ends of both rotating shafts. A fixed cylinder 8 is fixedly connected to the middle of the rear inner wall of the working chamber 1. An external gear ring is fixedly connected to the front end of the outer surface of the fixed cylinder 8. Two gears... All wheels 9 are meshed with external gear rings. Crossbars are fixedly connected to both the upper and lower ends of the two turntables 5. Scrapers 10 are fixedly connected to the middle of each crossbar. A second motor 11 is located at the rear end of the left side surface of the working chamber 1. A drive pulley 12 is fixedly connected to the rear end of the output shaft of the second motor 11. A driven pulley 13 is fixedly connected to the rear end of the rotating shaft 6. The drive pulley 12 and the driven pulley 13 are connected by a transmission belt. The input end of the second motor 11 is electrically connected to the output end of the control switch group 14. Evenly distributed through holes are provided at the lower end of the grinding chamber 2. The upper end and the upper end of the working chamber 1 are connected by a feeding hopper. The lower end of the working chamber 1 is equipped with a discharge hopper. The motor 11 is operated by the control switch group 14. The output shaft of the motor 11 rotates, which drives the drive pulley 12 to rotate. The drive pulley 12 drives the driven pulley 13 to rotate through the transmission belt. The driven pulley 13 rotates, which drives the rotating shaft 6 to rotate. The rotating shaft 6 rotates, which drives the two turntables 5 to rotate. The rotation of the turntables 5 drives the two rotating shafts to rotate around the central axis of the rotating shaft 6, which in turn drives the corresponding gear 9 to rotate around the central axis of the rotating shaft 6. Because the gear 9 and the outer... The gear ring meshing connection causes the gear 9 to rotate during its revolution, which in turn causes the two grinding rollers 7 to rotate around the central axis of the rotating shaft 6. The three grinding rollers 7 and the inner wall of the grinding chamber 2 support each other, realizing the fine grinding of RD01 ultrafine calcium powder raw material. At the same time, the rotation of the two turntables 5 drives the two crossbars to rotate, which in turn drives the two scrapers 10 to rotate around the central axis of the rotating shaft 6, realizing the scraping of RD01 ultrafine calcium powder from the inner wall of the grinding chamber 2. The finely ground RD01 ultrafine calcium powder falls into the discharge hopper through evenly distributed through holes, and then is removed through the discharge hopper.

[0027] The working principle of the calcium powder ultrafine grinding mill provided by this utility model is as follows: During operation, the operator first places the working chamber 1, grinding chamber 2, and other mechanisms stably in the horizontal working area. After the placement is stable, the operator adds RD01 ultrafine calcium powder raw material into the grinding chamber 2 through the feed hopper. Then, the operator controls the switch group 14 to start the motor 11. The output shaft of the motor 11 rotates, driving the drive pulley 12 to rotate. The drive pulley 12 drives the driven pulley 13 to rotate through the transmission belt. The driven pulley 13 rotates, driving the rotating shaft 6 to rotate. The rotating shaft 6 rotates, driving the two turntables 5 to rotate. The turntables 5 rotate, driving the two rotating shafts to rotate around the central axis of the rotating shaft 6, thereby driving the corresponding gears 9 to rotate around the central axis of the rotating shaft 6. The rotation, due to the meshing connection between gear 9 and the external gear ring, causes gear 9 to rotate on its own axis during its revolution, which in turn causes the two grinding rollers 7 to rotate on their own axes while rotating around the central axis of the rotating shaft 6. The three grinding rollers 7 and the inner wall of the grinding chamber 2 support each other, realizing the fine grinding of RD01 ultrafine calcium powder raw material. At the same time, the rotation of the two turntables 5 drives the two crossbars to rotate, which in turn drives the two scrapers 10 to rotate around the central axis of the rotating shaft 6, realizing the scraping of RD01 ultrafine calcium powder on the inner wall of the grinding chamber 2. The finely ground RD01 ultrafine calcium powder falls into the discharge hopper through evenly distributed through holes, and then is removed through the discharge hopper. At the same time, the control switch group 14 realizes the operation of motor 41. The output shaft of motor 41 rotates, which drives the drive shaft to rotate. The drive shaft rotates, which drives the drive handle 4. 2. Rotation: The drive handle 42 rotates, causing the upper end of the connecting rod 43 to rotate around the central axis of the drive shaft via the second pin. When the drive handle 42 rotates upward, it pulls the upper end of the connecting rod 43 upward via the second pin, causing the lower end of the connecting rod 43 to pull the sliding frame 44 upward under the guidance of the guide rod 49 via the first pin. When the drive handle 42 rotates downward, it drives the upper end of the connecting rod 43 downward via the second pin, causing the lower end of the connecting rod 43 to push the sliding frame 44 downward under the guidance of the guide rod 49 via the first pin. As the drive handle 42 rotates in a circular motion, the sliding frame 44 performs a vertical periodic movement. When the sliding frame 44 moves downward, the connecting shaft drives the corresponding sliding groove 45 to slide internally. When the sliding frame 44 moves downward, it pushes the two rotating handles 46 to rotate closer to the center of the working chamber 1, which in turn causes the two rotating shafts 47 to rotate closer to the center of the working chamber 1. This ultimately causes the evenly distributed striking handles 48 to rotate closer to the center of the working chamber 1. The upper ends of the striking handles 48 strike the outer wall of the grinding chamber 2, and the lower ends strike the inner wall of the working chamber 1. When the sliding frame 44 moves upward, the connecting shafts drive the corresponding sliding grooves 45 to slide internally. Simultaneously, the upward movement of the sliding frame 44 pulls the two rotating handles 46 to rotate away from the center of the working chamber 1, which in turn causes the two rotating shafts 47 to rotate away from the center of the working chamber 1. Ultimately, this causes the evenly distributed striking handles 48 to rotate away from the center of the working chamber 1.The upper ends of the striking handles 48 strike the inner wall of the working chamber 1, while the lower ends strike the outer wall of the grinding chamber 2. As the sliding frame 44 moves vertically and periodically, the striking handles 48 intermittently strike the working chamber 1 and the grinding chamber 2, preventing RD01 ultrafine calcium powder from remaining on the inner walls of these chambers due to static electricity.

[0028] It is worth noting that the control switch group 14 disclosed in the above embodiments is provided with control buttons that correspond one-to-one with motor 1 41 and motor 2 11 and control their switching.
