Description

Technical Field

[0001] This invention belongs to the field of stone brick processing, and more specifically, it relates to a raw material mixing device for stone brick processing. Background Technology

[0002] Stone brick processing raw material mixing is a key process in which stone aggregates and mineral powders are mixed evenly in a specific gradation ratio to form a blank or concrete mixture with formability and target properties.

[0003] Currently, in the raw material mixing process of stone brick processing, different stone aggregates and mineral powders are usually poured into a mixing cylinder through a feed hopper for mixing. However, the flared structure of the feed hopper of the traditional mixing cylinder is exposed. Therefore, during the pouring process of stone aggregates and mineral powders into the flared part of the feed hopper, the impact of the stone aggregates and the disturbance of the powders as they fall will generate a large amount of stone dust that will be scattered into the external working environment of the mixing cylinder, polluting the air environment of the processing workshop. In addition, stone aggregates and mineral powders will form clumps during storage. Since the feed part of the traditional mixing cylinder does not have a pre-crushing function for stone aggregates and mineral powders, it is difficult to mix the stone aggregates and mineral powders evenly during the mixing operation. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a raw material mixing device for stone brick processing, which solves the problems of large amounts of stone dust polluting the air environment of the processing workshop and the difficulty in uniformly mixing agglomerated materials during the traditional mixing cylinder's feeding hopper pouring stone aggregates and mineral powders.

[0007] Furthermore, the outer side of the rotating cylinder is provided with a circular through hole, and a rotating rod is rotatably connected inside the circular through hole of the rotating cylinder. Two sets of stirring plates are fixedly connected to the outer side of the rotating rod. Each set of stirring plates is an arc-shaped curved plate structure.

[0009] Furthermore, the exhaust pipe is a cylindrical structure with an opening on the lower side. Thirty sets of ventilation slots are arranged around the outer side of the exhaust pipe near the top. The fan discs are distributed on the inner side of the cylindrical structure of the exhaust pipe.

[0010] Furthermore, the number of the dispersing rods is eighteen groups, with six groups of dispersing rods arranged in a circular array around the vertical central axis of the rotating column, and the six groups of dispersing rods are arranged at equal intervals from top to bottom on the outer side of the rotating column.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1.

On the other hand, the support plate fixedly connected to the inner side of the bulk material cylinder drives the eighteen sets of dispersing rods fixedly connected to the outer side of the rotating column to rotate at high speed in the feeding hopper, so that the dispersing rods impact and disperse the lumpy material falling in the feeding hopper, so that the stone processing raw materials fall into the mixing cylinder in a loose state through the circular through hole of the V-shaped path of the bulk material cylinder, thereby improving the mixing uniformity of the stone processing raw materials.

[0014] 2. In this invention, a fan motor drives a fan disc fixedly connected to the outer side of the transmission rod to rotate at high speed in the extraction pipe. This causes the fan disc to agitate the air inside the extraction pipe, creating a negative pressure suction airflow inside the mixing cylinder. The mixing cylinder then generates a negative pressure suction airflow through the circular through-hole of the V-shaped path of the material dispensing cylinder to the feeding hopper. This achieves the wind-powered suction of stone aggregate and mineral powder dust from the flared top of the feeding hopper, preventing dust from flying and dispersing through the feeding hopper and reducing the pollution of the workshop air environment by stone dust.

[0027] like Figures 1 to 11As shown, the present invention provides a raw material mixing device for stone brick processing, including a frame 4; a foot plate seat 2 is fixedly connected to the outer side of the frame 4, and a controller 5 is fixedly connected to the outer side of the frame 4. The controller 5 is a PLC controller, and a mixing cylinder 6 is fixedly connected to the inner side of the frame 4; it also includes a feeding hopper 1 and a suction device 22; the suction device 22 includes a fan motor 2201, a suction pipe 2202, a fan disc 2203, a transmission rod 2204, a cover shell 2205, and a filter pad 2206; the bottom end of the suction pipe 2202 is fixedly connected to the cover shell 2205, and the inner side of the cover shell 2205 is fixedly connected to the filter pad 2206; the top end of the suction pipe 2202 is equipped with the fan motor 2201, and the transmission rod 2204 is installed on the motor shaft of the fan motor 2201; the outer side of the transmission rod 2204 is fixedly connected to the foot plate seat 2. A fan disc 2203 is attached; a cylinder cover 25 is fixedly connected to the outer side of the feed hopper 1; a baffle plate 12 is fixedly connected to the inner side of the cylinder cover 25; a mixing cylinder 6 is fixedly connected to the lower side of the cylinder cover 25; a feeding motor 10 is installed on the upper side of the cylinder cover 25; a drive gear 11 is installed on the motor shaft of the feeding motor 10; a material dispersing cylinder 13 is rotatably connected to the center of the bottom end of the cylinder cover 25; a support plate 23 is fixedly connected to the inner side of the material dispersing cylinder 13; a rotating column 16 is fixedly connected to the center of the support plate 23; a dispersing rod 17 is fixedly connected to the outer side of the rotating column 16; a rotating cylinder 21 is fixedly connected to the bottom end of the material dispersing cylinder 13; a sleeve rod 24 is rotatably connected to the inner side of the rotating cylinder 21; a transverse bevel gear 20 is fixedly connected to the outer side of the sleeve rod 24; a support plate 18 is fixedly connected to the bottom end of the sleeve rod 24; and the mixing cylinder 6 is fixedly connected to both the left and right ends of the support plate 18.

[0028] In this embodiment of the invention, the outer side of the bulk material cylinder 13 is provided with an external tooth structure near the top. The drive gear 11 is meshed with the external tooth structure of the bulk material cylinder 13. The center of the bulk material cylinder 13 is provided with a circular through hole with a V-shaped path. When the spreading motor 10 drives the drive gear 11 to rotate, the drive gear 11 drives the bulk material cylinder 13 meshed with the outer side to rotate, continuously changing the orientation of the bottom opening of the circular through hole with the V-shaped path of the bulk material cylinder 13, so that the stone brick processing raw materials are evenly scattered in the mixing cylinder 6 during the feeding process, thereby improving the mixing efficiency of the stone brick processing raw materials in the mixing cylinder 6.

[0029] In this embodiment of the invention, the outer side of the rotating drum 21 is provided with a circular through hole, and a rotating rod 8 is rotatably connected inside the circular through hole of the rotating drum 21. Two sets of stirring plates 7 are fixedly connected to the outer side of the rotating rod 8. Each set of stirring plates 7 is an arc-shaped curved plate structure. A longitudinal bevel gear 19 is fixedly connected to the left end of the rotating rod 8. A transverse bevel gear 20 is meshed with the outer side of the longitudinal bevel gear 19. During the process of the material dispensing cylinder 13 rotating and sprinkling the raw materials for stone brick processing, the material dispensing cylinder 13 drives the rotating drum 21 to rotate, and the rotating drum 21 drives the rotating rod 8 to rotate around the vertical central axis of the rotating drum 21. Rotating and moving, the longitudinal bevel gear 19 meshes and rolls on the transverse bevel gear 20, causing the longitudinal bevel gear 19 to drive the stirring plate 7, which is fixedly connected to the outer side of the rotating rod 8, to flip and dig up and down in the mixing cylinder 6. This causes the stone brick processing raw material squeezed at the bottom of the mixing cylinder 6 to be stirred to the top area of ​​the mixing cylinder 6, avoiding the stratification of the stone brick processing raw material and improving the uniformity of the mixing of the stone brick processing raw material. A scraper 15 is fixedly connected to the outer side of the rotating cylinder 21 near the bottom, and a transverse stirring rod 9 is fixedly connected to the outer side of the rotating cylinder 21.

[0030] In this embodiment of the invention, a wiping pad 14 is fixedly connected to the outer side of the scraper 15. The wiping pad 14 is made of nitrile rubber. Utilizing the good flexibility and elasticity of nitrile rubber, the wiping pad 14 is always elastically and tightly attached to the inner wall of the mixing cylinder 6 and rotates and scrapes with the scraper 15. This allows the wiping pad 14 to cover and scrape away the stone brick processing raw materials adhering to the cylinder wall, thus avoiding the stone brick processing raw materials adhering to the cylinder wall of the mixing cylinder 6 and causing material waste.

[0031] In this embodiment of the invention, the exhaust pipe 2202 is a cylindrical structure with an opening on the lower side. Thirty sets of ventilation slots are arranged around the outer side of the exhaust pipe 2202 near the top. The fan disc 2203 is distributed on the inner side of the cylindrical structure of the exhaust pipe 2202. During the high-speed rotation of the fan disc 2203 fixedly connected to the outer side of the transmission rod 2204 driven by the fan motor 2201, the fan motor 2201 agitates the air in the exhaust pipe 2202 to form a negative pressure, so that the outside air is drawn into the mixing cylinder 6 through the V-shaped path circular through hole of the feed hopper 1 and the bulk material cylinder 13. The air in the mixing cylinder 6 is discharged from the ventilation slot through the exhaust pipe 2202, so that a negative pressure suction airflow is formed at the feed hopper 1. The dust generated by the stone brick processing raw materials being poured at the opening of the feed hopper 1 is drawn into the mixing cylinder 6 through the negative pressure airflow, avoiding the dust from the stone brick processing raw materials being poured outward and polluting the air environment of the production and processing workshop.

[0032] In this embodiment of the invention, there are eighteen sets of dispersing rods 17. Each set of six dispersing rods 17 is arranged in a circular array around the vertical central axis of the rotating column 16. Each set of six dispersing rods 17 is arranged at equal intervals from top to bottom on the outer side of the rotating column 16. During the synchronous rotation of the material dispersing cylinder 13 and the support plate 23, the support plate 23 drives the eighteen sets of dispersing rods 17 on the outer side of the rotating column 16 to crush and disperse the lumpy stone brick processing raw materials in the feed hopper 1, so that the stone brick processing raw materials are dispersed into the mixing cylinder 6 in a loose state, thereby improving the mixing uniformity of the stone brick processing raw materials in the mixing cylinder 6.

[0033] In this embodiment of the invention, the bottom of the inner side of the mixing cylinder 6 is a conical structure with a centripetal inclination. A circular pipe running vertically through the center of the conical structure of the mixing cylinder 6 is provided. An electric discharge valve 3 is installed at the bottom of the circular pipe of the mixing cylinder 6. During the discharge process of the stone brick processing raw materials, the stone brick processing raw materials at the bottom of the mixing cylinder 6 slide down along the conical structure with gravity and are discharged into the electric discharge valve 3 at the bottom of the circular pipe of the mixing cylinder 6, thus avoiding the accumulation and waste of stone brick processing raw materials at the bottom of the mixing cylinder 6.

[0034] In this embodiment of the invention, the cover shell 2205 is a cylindrical cover structure with an opening on the lower side. The upper side of the cylindrical cover structure of the cover shell 2205 is densely covered with circular through holes running vertically. The bottom of the circular through holes of the cover shell 2205 is covered with a filter pad 2206. The filter pad 2206 is made of PTFE-coated polyester needle-punched felt. The filter pad 2206 filters and intercepts the dust in the mixing cylinder 6, preventing the mixing dust in the mixing cylinder 6 from being discharged into the outside air environment through the ventilation groove of the exhaust pipe 2202.

[0035] Specific usage and functions of this invention: In this invention, during the mixing of raw materials for stone brick processing, the operator activates the controller 5. The controller 5 controls the feeding motor 10 and the fan motor 2201 to start synchronously via wires. The fan motor 2201 drives the fan disc 2203, which is fixedly connected to the outer side of the transmission rod 2204, to rotate at high speed in the extraction pipe 2202. The fan disc 2203 agitates the air inside the extraction pipe 2202, creating a negative pressure airflow from bottom to top inside the extraction pipe 2202. The extraction pipe 2202 draws the air from the mixing cylinder 6 into the venting groove of the extraction pipe 2202 for discharge. The filter pad 2206, fixedly connected to the inner side of the cover shell 2205, filters the air flowing into the extraction pipe 2202, preventing dust in the mixing cylinder 6 from being trapped by the fan disc 2203. 3. The material is discharged through the ventilation channel of the exhaust pipe 2202. The mixing cylinder 6 forms an airflow through the V-shaped path circular through hole of the material dispensing cylinder 13 to the flared area of ​​the feed hopper 1, allowing the dust generated by the pouring of stone brick processing raw materials to be sucked into the mixing cylinder 6, preventing the dust from spreading to the outside of the feed hopper 1. The spreading motor 10 drives the drive gear 11 to rotate. Since the drive gear 11 is meshed with the external tooth structure on the outer side of the material dispensing cylinder 13, the drive gear 11 drives the material dispensing cylinder 13 to rotate. Then, the operator puts the stone aggregate and mineral powder into the feed hopper 1. At this time, the material dispensing cylinder 13 drives the rotating column 16 fixedly connected to the support plate 23 to rotate synchronously. The dispersing rod 17 fixedly connected to the outer side of the rotating column 16 disperses the agglomerated stone brick processing raw materials falling into the feed hopper 1. The raw materials for stone brick processing are broken down and then rotated and thrown into the mixing cylinder 6 through the circular through-hole of the V-shaped path of the bulk material cylinder 13. At this time, the bulk material cylinder 13 drives the rotating cylinder 21, which is fixedly connected to the bottom end, to rotate on the outer side of the sleeve rod 24. Since the rotating rod 8 is rotatably connected in the circular through-hole on the outer side of the rotating cylinder 21, the rotating cylinder 21 drives the rotating rod 8, the transverse stirring rod 9, and the scraper 15, which are fixedly connected to the outer side, to rotate and move horizontally around the vertical central axis of the rotating cylinder 21. The wiping pad 14, which is fixedly connected to the outer side of the scraper 15, moves and scrapes against the cylinder wall of the mixing cylinder 6 to prevent the raw materials for stone brick processing from adhering to the cylinder wall of the mixing cylinder 6. Since the longitudinal bevel gear 19, which is fixedly connected to the left end of the rotating rod 8, meshes with the transverse bevel gear 20, the longitudinal bevel gear 19 is fixedly connected to the left end of the rotating rod 8. During the horizontal rotation of the rotating rod 8, the longitudinal bevel gear 19 meshes and rolls with the helical teeth of the transverse bevel gear 20. The longitudinal bevel gear 19 drives the two sets of stirring plates 7 fixedly connected to the outer side of the rotating rod 8 to stir the stone brick processing raw materials in the mixing cylinder 6. The transverse stirring rod 9 then horizontally impacts and stirs the stone brick processing raw materials in the mixing cylinder 6. After stirring is completed, the controller 5 controls the feeding motor 10 and the fan motor 2201 to shut down synchronously through the wire. The operator manipulates the controller 5 to control the electric discharge valve 3 to open through the wire. The raw materials that have been mixed in the mixing cylinder 6 slide down the conical structure by gravity and are discharged into the electric discharge valve 3 at the bottom of the circular pipe of the mixing cylinder 6, thereby completing the mixing operation of the stone brick raw materials.
