Description

Technical Field

[0001] The present application relates to the technical field of putty powder processing equipment, and more specifically, to a grinding device for producing and processing interior wall putty powder. Background Art

[0002] The production and processing of putty powder mainly includes the selection of raw materials, grinding, mixing and packaging. First, high-quality base materials such as gypsum, white cement and putty resin are selected according to the formula to ensure the stability of their performance. Then, the raw materials are ground by industrial mills to achieve the required fineness, and the different ingredients are mixed evenly in a certain proportion to ensure the consistency and workability of the product.

[0003] After searching, the announcement number is CN117943188A, which discloses a crushing and grinding device for putty powder processing and a method thereof, including a support frame, a crushing end shell is fixedly connected to the inner side of the support frame, a crushing device is arranged inside the top of the crushing end shell, and the crushing device includes a drive shaft end shell, an upper cutting disc, a shoveling folding plate, a lower cutting disc, an extrusion block, and a pressure groove plate. The drive shaft end shell is fixedly connected to the bottom end of the transmission shrink tube, the upper cutting disc is fixedly connected to the outer side surface of the drive shaft end shell, the shoveling folding plate is fixedly connected to the outer side surface of the drive shaft end shell, the lower cutting disc is arranged below the upper cutting disc, the extrusion block is fixedly connected to the bottom surface of the lower cutting disc, and the pressure groove plate is fixedly connected to the inner wall of the crushing end shell. The upper cutting disc and the lower cutting disc move relative to each other, so as to increase the frequency of the block material being knocked and pressed, and the large block material is quickly crushed by high-frequency knocking, thereby improving the material crushing efficiency.

[0004] However, although the existing grinding device for putty powder production solves the problem of crushing large pieces of putty powder raw materials, it adopts the relative movement of the upper and lower cutting discs for crushing. This will lead to metal fatigue caused by the temperature increase during the long-term crushing of the putty powder raw materials, and the deformation of the upper and lower cutting discs, thereby reducing the crushing effect. In addition, the upper and lower cutting discs need to be replaced frequently, the equipment maintenance is too high, and the efficiency of crushing the bulk putty powder raw materials is not high enough.

[0005] In addition, the sieve plate after grinding screens the ground putty powder, using the elastic force of the spring to move back and forth, which will also reduce the screening effect due to metal fatigue of the spring.

[0006] Therefore, it is necessary to provide a grinding device for producing and processing interior wall putty powder to solve the above problems.

[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0053] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0054] See also Figure 1-8 , the embodiment provided by the present invention:

[0055] Example 1

[0056] like Figure 1 and Figure 2 As shown, a grinding device for producing and processing interior wall putty powder includes a grinding cylinder 2 for grinding interior wall putty powder raw materials. The grinding cylinder 2 is divided into a feed hopper 21, a crushing area 22, a grinding area 23, and a discharge port 24 from top to bottom. The bulk interior wall putty powder raw materials are put into the grinding cylinder 2 through the feed hopper 21, and the bulk interior wall putty powder raw materials are first crushed into small particles of interior wall putty powder raw materials in the crushing area 22, and then passed through the grinding area 23 to be ground and processed, and the finer interior wall putty powder ingredients are finally discharged from the grinding cylinder 2 through the discharge port 24.

[0057] Among them, a vibrating screen 10 is provided below the discharge port 24 of the grinding cylinder 2, and a loading elevator 11 is provided below the tilted discharge port 24 of the vibrating screen 10. The feeding end of the loading elevator 11 is located below the tilted discharge port 24 of the vibrating screen 10, and the discharge end of the loading elevator 11 is located in the feeding hopper 21. The ground interior wall putty powder ingredients are screened by the vibrating screen 10, so that the relatively large particles that have not been completely ground fall into the collecting bin at the feeding end of the loading elevator 11 through the tilted discharge port 24 of the vibrating screen 10, and are lifted by the loading elevator 11 and introduced into the feeding hopper 21 for re-crushing and grinding, thereby ensuring that the interior wall putty powder ingredients screened by the vibrating screen 10 are uniform and fine in coarseness, so as to improve the utilization rate of the interior wall putty powder raw materials.

[0058] Example 2

[0059] like Figure 4-6As shown, on the basis of Example 1, in order to better improve the crushing efficiency and effect and avoid metal fatigue deformation as much as possible, a crushing component 4 for crushing the interior wall putty powder raw material is fixedly installed inside the grinding cylinder 2 of the crushing area 22, and the crushing component 4 includes an outer cylinder 41 and a cone head 42. The top surface of the outer cylinder 41 is fixedly installed with a material guide component 3 for guiding large pieces of putty powder raw materials into the outer cylinder 41. The material guide component 3 includes a feed bin 31 and a conical material tray 32. The bottom surface of the feed bin 31 is fixedly connected to the conical material tray 32. The conical material tray 32 is an open-top and closed-bottom structure. The top surface of the feed bin 31 is fixedly connected to the conical material tray 32. The bottom discharge port 24 of the feed hopper 21 is connected, and the bottom surface of the feed bin 31 is fixedly connected with support rods 34. A fixing ring 33 is integrally formed at the bottom edge of the conical material tray 32. The top surface of the fixing ring 33 is fixedly connected to the support rod 34. The fixing ring 33 is fixedly installed with the bottom surface of the outer cylinder 41 by screws. After the large pieces of interior wall putty powder raw materials input from the feed hopper 21 are guided by the feed bin 31, the large pieces of interior wall putty powder are gathered at the bottom of the conical material tray 32 and finally enter the outer cylinder 41, so that the large pieces of interior wall putty powder raw materials are introduced into the crushing component 4 for crushing.

[0060] In this example, if Figure 5 As shown, a water cooling mechanism is provided inside the outer cylinder 41, a conical groove 415 is opened inside the outer cylinder 41, crushing teeth 416 are integrally formed around the surface of the conical groove 415, and the crushing teeth 416 are strip-shaped structures, the cone head 42 is located inside the conical groove 415, and spiral teeth 421 are integrally formed on the surface of the cone head 42, and a gap is provided between the spiral teeth 421 and the crushing teeth 416.

[0061] The crushing principle is as follows: large pieces of interior wall putty powder raw materials enter the conical groove 415 inside the outer cylinder 41 under the guidance of the material guide component 3, but cannot fall directly due to the obstruction of the cone head 42, and slide into the gap provided between the spiral teeth 421 and the crushing teeth 416. When the cone head 42 rotates, the spiral teeth 421 rotate along the axis on its surface as the cone head 42 rotates. Since the spiral teeth 421 are spiral and the crushing teeth 416 are strip-shaped, the large pieces of interior wall putty powder raw materials act on the crushing teeth 416 under the inclined pushing action of the spiral teeth 421, so that they are squeezed and crushed under different movement trajectories of the crushing teeth 416 and the spiral teeth 421. After the large pieces of interior wall putty powder raw materials are broken into small pieces, they are gradually crushed from the top side wall to the bottom side wall of the cone head 42, so that the large pieces of interior wall putty powder raw materials after passing through the crushing component 4 are crushed into small pieces of interior wall putty powder raw materials.

[0062] like Figure 6As shown, in order to prevent the problem of metal fatigue caused by the increase of the inner surface temperature of the outer cylinder 41 due to long-term operation, the water cooling mechanism includes a water inlet pipe 411, a water outlet pipe 412, a water tank 413 and a connecting groove 414. The side walls of the outer cylinder 41 are respectively provided with a water inlet and a water outlet. The water inlet is connected to the water inlet pipe 411, and the water outlet is connected to the water outlet pipe 412. A plurality of water tanks 413 are provided inside the outer cylinder 41. The plurality of water tanks 413 are connected through the connecting groove 414. The water tanks 413 are connected with the water inlet and the water outlet, respectively. Cooling liquid is introduced into the water tank 413 inside the outer cylinder 41 through the water inlet pipe 411. The cooling liquid flows in the plurality of water tanks 413 through the plurality of connecting grooves 414, and is finally discharged through the water outlet pipe 412, so as to form a water circulation system, and reduce the inner surface temperature of the outer cylinder 41, so as to ensure that the temperature of the outer cylinder 41 does not increase during the crushing process.

[0063] Furthermore, a surrounding plate 422 is fixedly connected to the bottom surface of the cone head 42, and a cavity is formed between the outer periphery of the surrounding plate 422 and the grinding cylinder 2 for the crushed interior wall putty powder raw materials to pass through. The small pieces of interior wall putty powder raw materials are blocked by the surrounding plate 422 and enter the grinding area for grinding processing through the cavity.

[0064] It is worth mentioning that the center of the bottom surface of the cone head 42 is fixedly installed with the top end of the main shaft rod 7, and the side wall of the main shaft rod 7 is rotatably connected with the axial positioning assembly 5. The axial positioning assembly 5 is fixedly installed in the interior of the grinding cylinder 2 between the crushing area 22 and the grinding area 23. The axial positioning assembly 5 includes a shaft seat 51 and a conical cover 53. The interior of the shaft seat 51 is rotatably connected with the side wall of the main shaft rod 7 through a bearing. One circle of the shaft seat 51 is fixedly installed on the axis inside the grinding cylinder 2 through a support rod 52. The bottom surface of the shaft seat 51 is fixedly installed with the conical cover 53, and the conical cover 53 is a structure that is retracted at the top and opened at the bottom.

[0065] The rotation of the main shaft 7 provides the cone head 42 with rotational power. In order to ensure that the main shaft 7 rotates along the axis, the shaft seat 51 and the support rod 52 provide axial rotation for the main shaft 7, so that the cone head 42 rotates in the conical groove 415 and is not easily offset. At the same time, the conical cover 53 with an upper-retracted and lower-open structure guides the small pieces of interior wall putty powder raw materials that fall, and then falls on the grinding assembly for grinding treatment, thereby providing guidance for the small pieces of interior wall putty powder raw materials.

[0066] Example 3

[0067] like Figure 8As shown, on the basis of Example 1 and Example 2, in order to better grind the small pieces of interior wall putty powder raw materials, a grinding assembly 6 is fixedly installed inside the grinding cylinder 2 of the crushing area 22, and the grinding assembly 6 includes an outer ring 61 and a grinding disc 62. The inner side wall of the outer ring 61 is provided with a grinding groove 611, and the outer ring 61 is fixedly installed on the inner side wall of the grinding cylinder 2. The inside of the grinding disc 62 is fixedly connected to the side wall of the main shaft rod 7 and is rotatably connected inside the outer ring 61. The grinding assembly 6 is at least There are three groups, and the three groups of grinding components 6 are installed in parallel in the grinding area 23 inside the grinding cylinder 2. The top surface of the grinding disc 62 located at the top of the three groups of grinding components 6 is a conical structure. Through the conical surface design, small pieces of interior wall putty powder raw materials slide into the gap between the outer ring 61 and the grinding disc 62. The outer side walls of the grinding disc 62 are respectively provided with notches 621 at equal angles, and the notches 621 are fixedly connected with fixed shaft rods 622, and the grinding ring 623 is sleeved on the side wall of the fixed shaft rod 622.

[0068] When the main shaft rod 7 drives the grinding disc 62 to rotate in the outer ring 61, since the grinding ring 623 has an axial hole for the fixed shaft rod 622 to pass through, and the diameter of the axial hole is 2-3CM larger than the diameter of the fixed shaft rod 622, multiple grinding rings 623 slide into the grinding groove 611 opened in the outer ring 61 under the action of centrifugal force, so that the small pieces of interior wall putty powder raw materials are hit and rubbed by multiple grinding rings 623 layer by layer and are ground into powdery interior wall putty powder raw materials, thereby achieving the effect of grinding the interior wall putty powder raw materials.

[0069] It is worth noting that the top edge and the bottom edge of the grinding ring 623 are both set to arc-shaped fillets. The design of the arc-shaped fillets can facilitate small pieces of interior wall putty powder raw materials to enter the gap between the outer ring 61 and the grinding disc 62.

[0070] Among them, Figure 1 and Figure 8As shown, in order to provide power for the grinding assembly 6 and the crushing assembly 4, the bottom end of the main shaft rod 7 is connected to the output shaft of the driving motor 9 through the transmission assembly 8, the driving motor 9 is fixedly installed on the top surface of the frame 1, the side wall of the grinding cylinder 2 is fixedly installed on the top surface of the frame 1 through a limit plate, the vibrating screen 10 is installed inside the frame 1, and the feeding elevator 11 is fixedly installed on the side wall of the frame 1 and is located on one side of the grinding cylinder 2 and the vibrating screen 10. The transmission assembly 8 includes two supports 81, a rotating rod 82, two bevel gears 83 and an output rod 84. The ear seats of the two supports 81 are fixedly installed through a fixed shaft, and the rotating rod 82 is rotatably connected inside the two supports 81 through bearings. The ends of the rotating rods 82 inside the two supports 81 are respectively connected to the internal keys of the two bevel gears 83, and the two bevel gears 83 are meshed with each other. One of the rotating rods 82 is fixedly connected to the bottom end of the main shaft rod 7, and the other rotating rod 82 is fixedly connected to one end of the output rod 84. The other end of the output rod 84 is connected to the driving motor 9 through a gearbox. The driving motor 9 provides rotational power to the output rod 84 after passing through the gearbox, and drives the two rotating rods 82 and the two bevel gears 83 of the transmission assembly 8 to rotate in the two supports 81, thereby driving the main shaft rod 7 to rotate, so that the cone head 42 and multiple grinding discs 62 inside the grinding cylinder 2 rotate, and the interior wall putty powder raw materials are crushed and ground respectively.
