Description

Technical Field

[0001] This invention relates to the field of industrial technology, specifically to an energy-saving grinding device for building adhesive mortar powder. Background Technology

[0002] In the construction industry, building adhesive mortar powder is an important bonding material. The quality and efficiency of its grinding process directly affect the subsequent construction effect. Traditional powder grinding equipment has many problems in practical applications: insufficient grinding and poor screening effect: traditional equipment mostly adopts a single grinding structure, which easily leads to uneven grinding of the powder during the grinding process. Moreover, it lacks an effective grading and screening mechanism, resulting in the finished product containing particles of different sizes, affecting the bonding performance and stability of the powder. Although some equipment has a screening stage, the screening structure is fixed and cannot adapt to the processing of powders with different fineness requirements, resulting in low screening efficiency, high energy consumption, and serious resource waste: the drive and grinding component design of traditional grinding equipment is not optimized enough. During the grinding process, a lot of energy is required to maintain the operation of the equipment. At the same time, the residual material after grinding is easy to adhere to the internal structure of the equipment, which not only affects the subsequent grinding accuracy but also requires regular shutdown for cleaning, further increasing energy consumption and labor costs, which is inconsistent with the industry development trend of energy conservation and consumption reduction.

[0003] Difficult to clean and high maintenance costs: Due to the stickiness of the adhesive powder, it is easy to adhere to the inner wall of the device, grinding parts and screening structure during grinding and screening. The cleaning of traditional devices mostly relies on manual disassembly and cleaning, which is cumbersome and difficult to completely remove residual materials. Long-term use will lead to increased wear and tear on the equipment, shorten its service life and increase maintenance costs.

[0004] Chinese patent CN210846616U discloses an invention in the field of building construction technology, which discloses a grinding device for building adhesive mortar powder. The device includes a machine body, a mixing hopper, a grinding chamber, a screening box, a dust container, a partition plate, a large particle container, and a base. The bottom of the mixing hopper is fixedly connected to the middle of the top of the grinding chamber. A partition plate is provided between the dust container and the large particle container. The bottom of the grinding chamber is fixedly connected to the top of the screening box. The bottom of the screening box is connected to both the dust container and the large particle container. The top of the base is fixedly connected to the bottom of the machine body. The key technical point is that the raw material is crushed by the mixing blades on the mixing rod, achieving the effect of initial processing. In this grinding device for building adhesive mortar powder, a screening motor drives the fan blades inside the screening box to rotate, allowing the ground raw material to pass through a filter screen into the dust container.

[0005] Traditional equipment often uses a single grinding structure, which can easily lead to uneven grinding of the adhesive powder during the grinding process. The adhesive powder adheres to the surface of the separator and is difficult to clean. Long-term use will lead to accelerated wear and tear on the equipment, shorten its service life, and increase maintenance costs. Summary of the Invention

[0008] By combining the cleaning and screening components, the adhesive powder is screened and cleaned, thereby further improving work efficiency.

[0009] Furthermore, the cleaning assembly includes a water tank, a water pipe, a first pipe, a second pipe, a second annular drain pipe, and nozzles. Two holes are opened at one end of the outer shell of the separator. The top of the water tank is fixedly connected to the water pipe, and the center of the outer side of the water pipe is fixedly connected to the first pipe, while the top of the water pipe is fixedly connected to the second pipe.

[0014] Through the above technical solution, the screening component allows large dust particles to be returned while small dust particles are blown away, further refining the particles and improving the efficiency of traditional manual screening.

[0015] Furthermore, the bottom of the turntable is fixedly connected to multiple inclined rods, and the bottom of the inclined rods is fixedly connected to a sliding plate. The inside of the sliding plate is slidably connected to a lead screw, and the inside of the lead screw is rotatably connected to the bottom of the support column.

[0016] Through the above technical solution, the lead screw drives the slide to vibrate on the spring, causing the screening component to shake and shake off the residual dust.

[0017] Furthermore, a spring is fixedly connected to the bottom of the slide plate, and the bottom of the spring is fixedly connected to the center of the outer side of the spreading disc.

[0018] The above technical solutions increase buffering performance and reduce the amount of friction generated between machines.

[0019] Furthermore, a hole is provided on one side of the top plate, and a discharge port is fixedly connected to the outside of the hole; a hole is provided on one side of the anti-splash shell, and a conveying pipe is fixedly connected to the outside of the hole; and a feed inlet is fixedly connected to the top of the conveying pipe.

[0020] The above technical solution involves using a pipe inside the hole to transport liquid for cleaning.

[0021] Furthermore, a blower body is fixedly connected to the top center of the chassis, and an air outlet is provided at the top center of the blower body. An air inlet is provided on one side of the blower body and a connecting rod is rotatably connected to the other side. A motor is fixedly connected to the outer end of the connecting rod away from the blower body, and a mounting base is fixedly connected to the outer side of the motor.

[0022] Through the above technical solution, the blower blows fine dust upwards through the air inlet, and the dust is collected from the outlet.

[0023] Furthermore, a grinding disc is rotatably connected to the center of the splashproof shell, and an air outlet is provided inside the grinding disc. A second motor is fixedly connected to the bottom of the grinding disc, and three sets of grinding rollers abut against the top of the grinding disc.

[0025] Furthermore, a support column is fixedly connected to one side of the grinding roller, and the bottom of the support column is fixedly installed on the top of the grinding disc. A fixing rod is fixedly connected to the other side of the grinding roller, and a central column is fixedly connected to the outside of the fixing rod. The bottom of the central column is fixedly connected to the top center of the grinding disc.

[0026] With the above technical solution, the grinding roller is fixed on the top of the grinding disc, and the rotating grinding disc drives the roller to rotate, causing friction on large particles of material.

[0027] The above-described solution of the present invention has at least the following beneficial effects: This invention uses a cleaning component that guides water flow to a ring-shaped drainage pipe via water pipes, pipe one, pipe two, and other structures. The water then passes through multiple nozzles to thoroughly rinse the interior of the separator, the screening components, and the grinding parts. This quickly removes any adhering adhesive residue, avoiding the tedious manual cleaning process. The ring-shaped drainage pipe design ensures more even nozzle distribution, eliminating blind spots in the cleaning process. This reduces the corrosion and wear caused by material residue, extends the equipment's lifespan, and lowers the frequency and cost of maintenance and component replacement.

[0028] This invention achieves graded screening of adhesive powder through the synergistic effect of screening components. The spreading disc evenly disperses the material, and the turntable and separator work together to form a multi-layer screening space, which can accurately separate adhesive powder of different particle sizes, ensuring that the finished product has a consistent particle size and meeting the strict requirements of building adhesive mortar for the fineness of adhesive powder. The screening components are made to vibrate up and down by springs, which works in conjunction with the turntable. Attached Figure Description

[0031] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0032] like Figures 1 to 8 As shown, an embodiment of the present invention provides an energy-saving grinding device for building adhesive mortar powder, comprising: The system comprises: a chassis 1; a filter screen 2, the exterior of which has multiple holes of the same size, and the bottom of which is fixedly mounted on the top of the chassis 1; a splash-proof housing 3, the interior of which is hollow, and the bottom of which is fixedly mounted on the top of the filter screen 2; a separator housing 4, the exterior of which is trapezoidal, the interior of which is hollow, and a circulation structure inside; a water tank 8, the interior of which is hollow, and a water pump 34 is fixedly connected inside, with holes at the top; a cleaning component, installed inside the separator housing 4, for cleaning the internal structure of the separator housing 4; and a screening component, installed inside the separator housing 4, for screening the adhesive powder by size.

[0033] In this embodiment, the material first enters through the feed inlet 6 and is then conveyed into the anti-splash housing 3 through the conveying pipe 7. The anti-splash housing 3 effectively blocks any splashing of rubber powder during the grinding process, preventing material waste and environmental pollution. Inside the anti-splash housing 3, the grinding disc 16 and multiple sets of grinding rollers 18 work together to grind the material. The screening components inside the separator housing 4 begin to operate, and the spreading disc 24 evenly disperses the material. The rotating disc 28 drives the short rod 25 and the spreading disc 24 to move. Combined with the action of the separator 29 and the top plate 30, the rubber powder is screened by size to meet the requirements. The required adhesive powder is discharged through the corresponding structure, while the substandard powder is returned to the grinding stage for reprocessing through the circulation structure inside the separator shell 4. When cleaning is required, the water pump 34 in the water tank 8 is started, and water is transported through the water pipe 31 to pipe 1 32 and pipe 2 33, which flow into the annular drainage pipe 1 35 and annular drainage pipe 2 36 respectively. Then, multiple nozzles 37 are used to thoroughly rinse the internal structure of the separator shell 4 and the screening components, achieving automatic cleaning and ensuring the accuracy and stability of the subsequent operation of the device. The bottom of the entire device is stably supported by the chassis 1.

[0034] like Figures 1 to 8 As shown, the cleaning assembly includes a water tank 8, a water pipe 31, a first pipe 32, a second pipe 33, a second annular drain pipe 36, and a nozzle 37. Two holes are opened at one end of the outer shell 4 of the separator. The top of the water tank 8 is fixedly connected to the water pipe 31, and the center of the outer shell of the water pipe 31 is fixedly connected to the first pipe 32. The top of the water pipe 31 is fixedly connected to the second pipe 33. The outer shell of the first pipe 32 is fixedly connected to the second annular drain pipe 36, and the interior of the second annular drain pipe 36 is hollow. Multiple nozzles 37 are fixedly connected to the bottom of the second annular drain pipe 36. The outer shell of the second pipe 33 is fixedly connected to the first annular drain pipe 35, and the interior of the first annular drain pipe 35 is hollow. Multiple nozzles 37 are fixedly connected to the bottom of the first annular drain pipe 35.

[0035] In this embodiment, when the cleaning component is working, the water pump 34 inside the water tank 8 starts, drawing water from the tank 8 and delivering it to the water pipe 31 fixedly connected to its top. The water flows through the water pipe 31, and a portion of the water is delivered to the annular drainage pipe 36 through the centrally fixed pipe 32 outside the water pipe 31. Since the annular drainage pipe 36 is hollow, water can flow through it and then be sprayed out through multiple nozzles 37 fixedly connected to the bottom of the annular drainage pipe 36, cleaning the corresponding structure inside the separator housing 4. Simultaneously, another portion of the water... The water is delivered to the annular drainage pipe 35 through the pipe 33 fixedly connected to the top of the water pipe 31. Since the interior of the annular drainage pipe 35 is also hollow, the water can flow inside and then be sprayed out through multiple nozzles 37 fixedly connected to the bottom of the annular drainage pipe 35 to clean other corresponding structures inside the separator housing 4. The two holes opened at one end of the separator housing 4 provide a channel for the pipe 32 and the pipe 33 to extend into the interior of the separator housing 4 and connect with the annular drainage pipe 36 and the annular drainage pipe 35, ensuring the normal operation of the cleaning components.

[0036] like Figures 1 to 6 As shown, the screening assembly includes a spreading disc 24, short rods 25, a fixing ring 27, a turntable 28, a separator 29, and a top plate 30. The top plate 30 is fixedly connected to the top of the separator housing 4, and multiple separators 29 are fixedly connected to the bottom of the top plate 30. The turntable 28 is fixedly connected to the bottom of the separator 29. The fixing ring 27 is rotatably connected inside the turntable 28, and a support column is fixedly connected inside the fixing ring 27. Multiple short rods 25 are fixedly connected to the bottom of the turntable 28, and the spreading disc 24 is fixedly connected to the bottom of the short rods 25. Multiple inclined rods 26 are fixedly connected to the bottom of the turntable 28, and a sliding disc 22 is fixedly connected to the bottom of the inclined rods 26. A lead screw 21 is slidably connected inside the sliding disc 22, and the lead screw 21 is rotatably connected to the bottom of the support column. A spring 23 is fixedly connected to the bottom of the sliding disc 22, and the bottom of the spring 23 is fixedly connected to the center of the outside of the spreading disc 24.

[0037] In this embodiment, after the adhesive powder enters through the inlet, it first falls onto the spreading disc 24. The spreading disc 24 is connected to the upper turntable 28 via a short rod 25. When the turntable 28 rotates, it drives the spreading disc 24 to rotate synchronously, using centrifugal force to evenly disperse the adhesive powder into the separator housing 4, providing a good dispersion state for subsequent screening. Multiple separators 29 at the bottom of the top plate 30 are arranged in a ring. When the adhesive powder is thrown into the area of ​​the separator 29, larger particles fall directly into the lower grinding disc 16 for further grinding due to gravity; smaller particles rise with the airflow and enter the interior of the separator 29 for fine screening. The turntable 28 at the bottom of the separator 29 is rotatably connected to the central support column via a fixing ring 27, and rotates at high speed under the drive of a motor. Rotation generates a centrifugal force field, and the adhesive powder particles are separated under the combined action of centrifugal force and airflow. Fine powder that meets the fineness requirements is discharged through the outlet of separator 29, while coarse particles are thrown against the inner wall of separator 29 and fall back to grinding disc 16 along the wall. Rotary disc 28 is connected to sliding disc 22 through inclined rod 26. Sliding disc 22 can slide along lead screw 21 and is connected to spreading disc 24 through spring 23. This structure gives spreading disc 24 a certain elastic buffer when rotating, reducing rigid collisions and extending service life. The elastic effect of spring 23 can also make spreading disc 24 vibrate slightly, preventing adhesive powder from accumulating on the disc and further improving screening efficiency.

[0038] like Figures 1 to 3 As shown, a hole is provided on one side of the top of the top plate 30, and a discharge port 5 is fixedly connected to the outside of the hole. A hole is provided on one side of the outside of the anti-splash shell 3, and a conveying pipe 7 is fixedly connected to the outside of the hole. A feed inlet 6 is fixedly connected to the top of the conveying pipe 7. A blower body 11 is fixedly connected to the center of the top of the chassis 1, and an air outlet 10 is provided at the center of the top of the blower body 11. An air inlet 12 is provided on one side of the outside of the blower body 11, and a connecting rod 13 is rotatably connected to the other side. A motor 14 is fixedly connected to the end of the connecting rod 13 away from the blower body 11. A mounting base 9 is fixedly connected to the outside of the motor 14.

[0039] In this embodiment, the rubber powder raw material is fed into the feed port 6 and enters the anti-splash housing 3 through the conveying pipe 7. The conveying pipe 7 is designed with an inclination to use gravity to assist the material to slide down, reducing the risk of blockage. The motor 14 drives the connecting rod 13, which drives the blower body 11 to operate. Air is drawn in from the air inlet 12 and sprayed out at high speed through the air outlet 10. The air outlet 10 is directly opposite the air supply port at the bottom of the grinding disc 16. The airflow passes through the gaps of the grinding disc 16, lifting the ground rubber powder particles to form an upward suspension flow. The rising airflow carries the rubber powder into the separator housing 4. Fine powder that meets the fineness requirements is discharged through the discharge port 5 of the top plate 30 with the airflow. Coarse particles fall back to the grinding disc 16 for grinding again due to gravity settling or centrifugal force.

[0040] like Figures 1 to 4As shown, a grinding disc 16 is rotatably connected to the center of the splash-proof shell 3, and an air outlet is provided inside the grinding disc 16. A motor 15 is fixedly connected to the bottom of the grinding disc 16, and three sets of grinding rollers 18 are abutted against the top of the grinding disc 16. A support column 17 is fixedly connected to one side of the outer side of the grinding roller 18, and the bottom of the support column 17 is fixedly installed on the top of the grinding disc 16. A fixing rod 19 is fixedly connected to the other side of the grinding roller 18, and a central column 20 is fixedly connected to the outside of the fixing rod 19. The bottom of the central column 20 is fixedly connected to the center of the top of the grinding disc 16.

[0041] In this embodiment, after the second motor 15 is started, it will drive the grinding disc 16, which is fixedly connected to it, to rotate in the center inside the splash-proof housing 3. Three sets of grinding rollers 18 are abutted against the top of the grinding disc 16. One side of these grinding rollers 18 is fixedly installed on the top of the grinding disc 16 by a support column 17, and the other side is connected to the central column 20 by a fixing rod 19. The bottom of the central column 20 is fixed to the center of the top of the grinding disc 16, which makes the grinding rollers 18 stably supported on the grinding disc 16. When the grinding disc 16 rotates, the friction of the grinding disc 16 will drive the three sets of grinding rollers due to the contact between the grinding rollers 18 and the surface of the grinding disc 16. 18 rotates around its own axis. At this time, the rubber powder material that has entered the anti-splash housing 3 will fall between the grinding disc 16 and the grinding roller 18. Under the relative rotation of the grinding disc 16 and the grinding roller 18, the material is crushed and ground into fine particles. At the same time, the air inlet opened inside the grinding disc 16 corresponds to the air outlet 10 of the blower body 11 below. The airflow generated by the blower will enter the upper part of the grinding disc 16 through the air inlet, blowing up the ground rubber powder particles and allowing them to enter the subsequent screening stage, avoiding the accumulation of material on the grinding disc 16 and ensuring the continuous and efficient operation of the grinding process.

[0042] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
