Description

Technical Field

[0001] This utility model belongs to the field of sandstone screening technology, specifically a sandstone screening and impurity removal device. Background Technology

[0002] Sandstone is a sedimentary rock mainly composed of sand grains cemented together by cementing agents. Due to its unique physical and chemical properties, sandstone is widely used in fields such as architecture and artistic sculpture.

[0003] Sand grains are the main component of sandstone, usually composed of minerals such as quartz, feldspar, and mica. During the sandstone processing, it is necessary to separate the impurities from the sandstone. Usually, the mined sandstone is initially crushed, and a vibrating screen is used to remove large impurities from the sandstone.

[0004] Traditional screen plates typically use unidirectional vibration, resulting in a single movement trajectory of sandstone on the screen. This makes it difficult to distribute the sandstone evenly on the screen, creating screening dead zones. Consequently, some materials are not effectively screened, and it is difficult to separate sandstone of multiple particle sizes simultaneously, leading to a decrease in sandstone screening efficiency.

[0005] Therefore, this utility model provides a sandstone screening and impurity removal device. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown, an embodiment of the present invention provides a sandstone screening and impurity removal device, comprising a screening box 1; a motor 11 is installed in the screening box 1; the output end of the motor 11 passes through the middle of the screening box 1; two connecting rings 12 are fixedly connected to the inner side wall of the screening box 1; the two connecting rings 12 are located at the end away from the motor 11; a first mesh cylinder 13 is fixedly connected to the output end of the motor 11; the end of the first mesh cylinder 13 is rotatably connected to the middle of one of the connecting rings 12; a second mesh cylinder 14 is fixedly connected to the middle of the first mesh cylinder 13; the end of the second mesh cylinder 14 is rotatably connected to the other connecting ring 12. The connecting ring 12 is located in the middle; two inlets and outlets 15 are installed at the end of the screening box 1; a cleaning component 2 is installed in the middle of the screening box 1; a collecting component 3 is installed at the bottom of the screening box 1; during operation, sandstone is placed into the second screen cylinder 14 through one of the inlets and outlets 15, and the control motor 11 is turned on, causing the output end of the motor 11 to drive the first screen cylinder 13 and the second screen cylinder 14 to rotate. The rotation speed of the output end of the motor 11 is controlled. During the rotation of the first screen cylinder 13 and the second screen cylinder 14, the ends rotate in the middle of the inlet and outlet 15, and the sandstone passes through... The second screen cylinder 14 rotates and rolls inside, leaving large sandstone particles in the middle of the second screen cylinder 14, while small particles are discharged through the pores of the second screen cylinder 14. The discharged sandstone enters the first screen cylinder 13, where the rotation of the first screen cylinder 13 causes even smaller particles to be discharged. The collection component 3 collects sandstone of the appropriate size. During the sandstone screening process, the washing component 2 washes the sandstone. The sandstone inside the first screen cylinder 13 and the second screen cylinder 14 is taken out from the middle of the inlet and outlet 15 for further processing. Through the above structure, the first screen cylinder 13 and the second screen cylinder 14 can be used to perform coarse and fine screening of sandstone at the same time, and can separate sandstone of multiple particle sizes at one time. Furthermore, the rotation of the first screen cylinder 13 and the second screen cylinder 14 during the screening process can make the sandstone evenly distributed on its surface, increase the fluidity of the sandstone inside the first screen cylinder 13 and the second screen cylinder 14, reduce the blockage and screening phenomenon of sandstone in the middle of the first screen cylinder 13 and the second screen cylinder 14, thereby improving the screening efficiency of sandstone and effectively shortening the screening time.

[0024] like Figures 1 to 3As shown, the cleaning assembly 2 includes a water pump 21; the water pump 21 is located at the end of the screening box 1; an inlet pipe 22 is fixedly connected to the middle of the water pump 21; an outlet pipe 23 is fixedly connected to the middle of the water pump 21; a drain pipe 24 is fixedly connected to the end of the outlet pipe 23; the drain pipe 24 is located inside the screening box 1; the drain pipe 24 is located near the top of the second screen cylinder 14; multiple spray heads 25 are installed in the middle of the drain pipe 24; the multiple spray heads 25 are equidistantly distributed; during operation, the end of the inlet pipe 22 is connected to the water source, and the water pump 21 is turned on, allowing water to pass through...

Through the above structure, the surface of the sandstone can be cleaned during the screening process to remove the attached clay and impurities. The water flow can moisten the sandstone, reduce the flying of dust during the screening process, and the spray water washes the first screen cylinder 13 and the second screen cylinder 14 to reduce the clogging of the screen by fine particles and sticky impurities.

[0025] like Figures 1 to 4 As shown, the collection component 3 includes support plates 33; two support plates 33 are fixed to the inner wall of the screening box 1; the two support plates 33 are arranged opposite each other; a collection frame 31 is installed at the bottom of the screening box 1; the collection frame 31 is located on top of the two support plates 33; a permeable plate 32 is fixed to the middle of the collection frame 31; a baffle 34 is fixed to the end of the collection frame 31; a handle 35 is fixed to the middle of the baffle 34; during operation, holding the handle 35, one end of the collection frame 31 is placed inside the screening box 1, and the baffle 34 is in contact with the outer wall of the screening box 1. After the sandstone is screened by the first screen cylinder 13, it falls into the permeable plate 32. The sandstone is collected by the collection frame 31, while the washed water is discharged to the bottom of the screening box 1 through the middle of the permeable plate 32. After the sandstone screening is completed, the collection frame 31 is pulled out from the screening box 1 to allow for further processing of the screened sandstone. The above structure allows sandstone particles that meet the particle size requirements to be easily pulled out, facilitating subsequent processing of the sandstone. It also makes it easy to replace and clean the permeable plate 32, reducing maintenance difficulty. The permeable plate 32 can separate water from sandstone, allowing the screened sandstone and washed water to be treated separately, increasing the screening efficiency of the sandstone.

[0026] like Figure 2 and Figure 3As shown, a fixing rod 4 is fixedly connected to the inner wall of the screening box 1; the fixing rod 4 is fixedly connected to the middle of the two inlets and outlets 15; a threaded brush 41 is rotatably connected to the middle of the fixing rod 4; during operation, the threaded brush 41 is in contact with the first screen cylinder 13 and the second screen cylinder 14. During the process of the first screen cylinder 13 and the second screen cylinder 14 rotating to screen the sandstone, the sandstone will get stuck in the gaps in the first screen cylinder 13 and the second screen cylinder 14. The threaded brush 41 rotates in the middle of the fixing rod 4 as the first screen cylinder 13 and the second screen cylinder 14 rotate. At the same time, the threaded brush 41 cleans the first screen cylinder 13 and the second screen cylinder 14. Through the above-mentioned structure, the threaded brush 41 can clean the surface of the first screen cylinder 13 and the second screen cylinder 14 in real time, reducing the blockage of the screen holes by fine particles and sticky impurities. By continuously cleaning the first screen cylinder 13 and the second screen cylinder 14 through the threaded brush 41, the clay and impurities attached to the middle of the first screen cylinder 13 and the second screen cylinder 14 can be removed in time, reducing the wear of the first screen cylinder 13 and the second screen cylinder 14 by the residue, and effectively reducing the maintenance frequency.

[0027] like Figure 1 and Figure 4 As shown, an activated carbon plate 5 is installed at the bottom of the screening box 1; the activated carbon plate 5 is located at the bottom of the permeable plate 32; a connecting pipe 51 is fixed to the side wall of the screening box 1; the end of the connecting pipe 51 is connected to one end of the inlet pipe 22; during operation, when the cleaning water flows through the permeable plate 32 and is discharged to the bottom of the screening box 1, the impurities and silt in the water flow are adsorbed by the permeable plate 32, so that the filtered clean water is discharged into the water pump 21 through the inside of the connecting pipe 51, and the sandstone is washed again by the water pump 21, thereby recycling the water. Through the above structure, the used water can be recycled, and the filtration by the activated carbon plate 5 can reduce the consumption of fresh water and reduce wastewater discharge, thereby reducing environmental pollution.

[0028] like Figure 2 As shown, a sealing gasket 6 is fixedly connected to the middle of the baffle 34; the sealing gasket 6 is fixed to the side near the collection frame 31; during operation, after the collection frame 31 is placed inside the screening box 1, the sealing gasket 6 is attached to the outer wall of the screening box 1 to fill the gap between the baffle 34 and the screening box 1. The above structure can effectively increase the sealing between the baffle 34 and the screening box 1, effectively reduce internal liquid leakage, and effectively increase the friction and contact area between the baffle 34 and the screening box 1, so that the baffle 34 fits the surface of the screening box 1 better.

[0029] like Figure 2As shown, a protective cover 7 is fixedly connected to the end of the screening box 1; the protective cover 7 is fixedly connected to the outside of the motor 11; multiple heat dissipation holes 71 are opened in the middle of the protective cover 7; during operation, the motor 11 is protected by the protective cover 7. During the use of the motor 11, the heat inside the motor 11 is discharged to the outside air through the middle of the multiple heat dissipation holes 71. The above structure can effectively reduce the direct contact between external objects and the motor 11, reduce the impact and damage to the motor 11, and can discharge heat to the outside airflow during protection, thereby increasing heat dissipation.

[0030] During operation, sandstone is placed into the second mesh cylinder 14 through one of the inlet / outlet 15. The control motor 11 is turned on, causing its output to rotate both the first and second mesh cylinders 13 and 14. The rotation speed of the motor 11 is controlled, and the ends of the first and second mesh cylinders 13 and 14 rotate in the middle of the inlet / outlet 15. The sandstone rolls inside the second mesh cylinder 14 as it rotates, with larger sandstone particles remaining in the middle and smaller particles being discharged through the openings. The discharged sandstone then enters the first mesh cylinder 13, where its rotation causes even smaller particles to be discharged. The collection assembly 3 collects the sandstone. Sandstone of appropriate size is collected. During the sandstone screening process, the sandstone is washed by the washing component 2. The sandstone inside the first screen cylinder 13 and the second screen cylinder 14 is taken out from the middle of the inlet and outlet 15 for further processing. The end of the water inlet pipe 22 is connected to the water source, and the water pump 21 is turned on, so that the water enters the middle of the drain pipe 24 through the outlet pipe 23. During the sandstone screening process, the water flows out through multiple spray heads 25. The high-pressure water flow makes the spray heads 25 rotate, and the water discharged from the spray heads 25 washes the sandstone. Hold the handle 35 and put one end of the collection frame 31 into the screening box 1. The baffle 34 is attached to the outer wall of the screening box 1. When the sandstone passes through the screen, the water flows out through the baffle 35. After screening by the first screen cylinder 13, the sandstone falls into the middle of the permeable plate 32 and is collected by the collection frame 31. Simultaneously, the washing water is discharged through the middle of the permeable plate 32 to the bottom of the screening box 1. After the sandstone screening is completed, the collection frame 31 is pulled out of the screening box 1 for further processing. The threaded brush 41 is attached to the first screen cylinder 13 and the second screen cylinder 14. During the process of the first screen cylinder 13 and the second screen cylinder 14 rotating to screen the sandstone, the sandstone will get stuck in the gaps between the first screen cylinder 13 and the second screen cylinder 14. The threaded brush 41 rotates in the middle of the fixed rod 4 as the first screen cylinder 13 and the second screen cylinder 14 rotate. At the same time, the threaded brush 41... The first screen cylinder 13 and the second screen cylinder 14 are cleaned. When the cleaning water flows through the permeable plate 32 and is discharged to the bottom of the screening box 1, the permeable plate 32 adsorbs the impurities and mud in the water flow. The filtered clean water is discharged into the water pump 21 through the connecting pipe 51. The water pump 21 cleans the sandstone again, thereby recycling the water. After the collection frame 31 is placed inside the screening box 1, it is attached to the outer wall of the screening box 1 by the sealing gasket 6. The gap between the baffle 34 and the screening box 1 is filled. The motor 11 is protected by the protective cover 7. During the use of the motor 11, the heat inside the motor 11 is discharged to the outside air through the middle of multiple heat dissipation holes 71.
