Description

Technical Field

[0001] This utility model relates to the field of sand washing machine technology, and more specifically to a sand washing machine for de-dusting manufactured sand. Background Technology

[0002] Manufactured sand refers to sand processed by a sand making machine and other auxiliary equipment. The finished product is more regular and can be processed into sand of different shapes and sizes according to different process requirements. Manufactured sand is an important building material for infrastructure such as buildings, roads, and bridges. Manufactured sand is made by first crushing stone in a coarse crusher, and then the coarse material produced is transported by a belt conveyor to a fine crusher for further crushing. The finely crushed stone is then screened by a vibrating screen to separate two types of stones. The stones that meet the feed particle size of the sand making machine are then fed into the sand making machine. To ensure the quality of construction when using manufactured sand, a sand washing machine is needed to remove the small powder particles in the manufactured sand.

[0003] Inadequacies of existing technology: In the process of using existing sand washing machines, manufactured sand is mostly transported to an inclined vibrating screen by a conveyor belt and then washed with water to achieve the purpose of washing sand and removing dust. However, when using a conveyor belt to transport manufactured sand, it is impossible to ensure that the manufactured sand falls evenly on the vibrating screen, and it is also impossible to accurately control the speed of conveying manufactured sand, which easily causes the manufactured sand to accumulate together and affects the quality of fine sand.

The sand washing machine for de-dusting of manufactured sand involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1 to 7This utility model provides a sand washing machine for de-dusting manufactured sand, including a sand washing mechanism 1, and further including a material distribution mechanism 2 and a feeding mechanism 3. The bottom end of the material distribution mechanism 2 is fixedly connected to the top end of the feeding mechanism 3, and the feeding mechanism 3 is located directly above the sand washing mechanism 1. The sand washing mechanism 1 includes a frame 101, a vibrating screen 105 is movably connected to the side of the frame 101, a top plate 102 is fixedly connected to the top end of the frame 101, a water nozzle is fixedly connected to the bottom end of the top plate 102, a water guide pipe 107 is fixedly connected to the side of the water nozzle, and a vibrating motor 10 is fixedly connected to the side of the frame 101. 4. A through slot 103 is provided on the side of the frame 101 corresponding to the position of the vibrating motor 104. The conveying shaft of the vibrating motor 104 is fixedly connected to the side of the vibrating screen 105. The feeding mechanism 3 includes a frame 301. A drive motor 303 is fixedly connected to the side of the frame 301. A transmission roller 305 is movably sleeved on the inner wall of the side of the frame 301. The side of the transmission roller 305 is fixedly connected to the output shaft of the drive motor 303. A conveyor belt 306 is drivenly connected to the side of the transmission roller 305. A discharge hopper 304 is fixedly connected to the top of the frame 301. The material distribution mechanism 2 includes a housing 201. The bottom end of the housing 201 is fixedly connected to the top end of the frame 301. An automatic telescopic rod 205 is fixedly connected to the inner wall of the top end of the housing 201. A baffle plate 202 is fixedly connected to the bottom end of the automatic telescopic rod 205. The side of the baffle plate 202 is movably connected to the inner side wall of the housing 201. According to the usage requirements, the automatic telescopic rod 205 drives the baffle plate 202 to move up and down along the inner side wall of the housing 201, so that the bottom end of the baffle plate 202 maintains a suitable distance from the top end of the conveyor belt 306, and the manufactured sand to be processed is poured into the discharge hopper 304 and falls onto the conveyor belt 306 under the action of gravity. The drive motor 303 drives the transmission roller 305 to rotate, causing the conveyor belt 306 to transport the manufactured sand to the right. When the conveyor belt passes the baffle plate 202, the baffle plate 202 blocks the manufactured sand, keeping the manufactured sand on the conveyor belt 306 at a suitable thickness, thereby controlling the conveying speed of the manufactured sand. The manufactured sand falls from the right side of the conveyor belt 306 onto the vibrating screen 105. The vibrating motor 104 drives the vibrating screen 105 to vibrate. The manufactured sand flows downward under the action of gravity and the vibration of the vibrating screen 105. At the same time, the water pipe 107 is connected to the water source and sprays water from the water nozzle to wash the manufactured sand and remove the powder.

[0026] Among them, the side of the baffle plate 202 is movably connected to the material distribution block 203. The cross-section of the material distribution block 203 is triangular. The material distribution block 203 divides the manufactured sand on the conveyor belt 306, so that the manufactured sand is evenly distributed on the top of the conveyor belt 306.

[0027] The baffle plate 202 has a sliding groove 206 on its side, and the material distribution block 203 has a slider 207 fixedly connected to its side. The side of the slider 207 is movably connected to the side of the sliding groove 206.

[0028] Among them, the slide 206 has a T-shaped structure, and the side of the slider 207 is movably connected to the roller through a pin. The side of the slide 206 is movably connected to the side of the roller.

[0029] The baffle plate 202 is fixedly connected to a drive motor 209 on its side. The output shaft of the drive motor 209 is fixedly connected to a turntable 210. The bottom end of the turntable 210 is movably sleeved with a mounting shaft 208. The side of the mounting shaft 208 is movably sleeved with a transmission rod 204. The bottom end of the transmission rod 204 is movably sleeved with the top end of the distribution block 203 by a pin. The mounting shaft 208 is located near the outer ring of the turntable 210. The drive motor 209 drives the turntable 210 to rotate, causing one end of the transmission rod 204 to rotate along the mounting shaft 208 and the other end to rotate along the top pin of the distribution block 203. This causes the distribution block 203 to move laterally and reciprocally along the side of the baffle plate 202, accelerating the diversion of the manufactured sand on the conveyor belt 306.

[0030] The frame 301 is fixedly connected to a guide hopper 302 on its side. The cross-section of the guide hopper 302 is trapezoidal, and the discharge port of the guide hopper 302 is located directly above the vibrating screen 105. The manufactured sand on the conveyor belt 306 falls into the guide hopper 302 and is evenly distributed on the top of the vibrating screen 105 after being guided.

[0031] The bottom inner wall of the guide hopper 302 is fixedly connected to a distribution plate 307, and the distribution plate 307 is evenly distributed in a fan shape inside the guide hopper 302. The distribution plate 307 further guides the manufactured sand, so that it falls evenly from the bottom of the guide hopper 302.

[0032] The bottom end of the frame 101 is fixedly connected to a sewage tank 106, and the bottom end of the frame 101 is provided with a through hole, through which the sewage tank 106 collects the flushing sewage.

[0033] The working principle of this utility model is as follows: According to usage requirements, the automatic telescopic rod 205 drives the baffle plate 202 to move up and down along the inner side wall of the housing 201, maintaining a suitable distance between the bottom end of the baffle plate 202 and the top end of the conveyor belt 306. The manufactured sand to be processed is poured into the discharge hopper 304 and falls onto the conveyor belt 306 under gravity. The drive motor 303 drives the transmission roller 305 to rotate, causing the conveyor belt 306 to transport the manufactured sand to the right. When the sand passes the baffle plate 202, the baffle plate 202 blocks it. Simultaneously, the drive motor 209 drives the turntable 210 to rotate, causing one end of the transmission rod 204 to rotate along the mounting shaft 208 and the other end to rotate along the top pin of the distribution block 203, thereby driving the distribution block 204... 3. The material moves laterally back and forth along the side of the baffle plate 202, diverting the manufactured sand in the middle of the conveyor belt 306 to both sides, so that it is evenly distributed on the top of the conveyor belt 306 and maintains a suitable thickness, thereby controlling the conveying speed of the manufactured sand. The manufactured sand falls into the guide hopper 302 from the right side of the conveyor belt 306, and is guided by the distribution plate 307 to fall evenly on the vibrating screen 105. The vibrating motor 104 drives the vibrating screen 105 to vibrate. The manufactured sand flows downward under the action of gravity and the vibration of the vibrating screen 105. At the same time, the water pipe 107 is connected to the water source and sprays water from the water outlet nozzle to wash the manufactured sand and remove the powder of the manufactured sand. The wastewater falls into the wastewater tank 106, and the finished manufactured sand falls from the right side of the vibrating screen 105.
