Description

Technical Field

[0001] This utility model relates to the field of manufactured sand gradation technology, and in particular to an intelligent control device for manufactured sand gradation. Background Technology

[0002] Grading of manufactured sand refers to the process of optimizing its performance by controlling the distribution ratio of particles of different sizes in the sand. This work mainly includes two key steps: First, the crushed manufactured sand is sorted using sorting equipment to separate it into several components according to particle size; then, according to the gradation specifications required by the application target, the sorted components are precisely blended, that is, a specific mixing ratio is calculated and set so that its particle distribution curve meets the expected requirements, thereby improving the bulk density, workability, and mechanical properties of the manufactured sand.

[0003] During the blending process, any slight deviation in proportion will cause the distribution of the entire particle system to deviate from the preset curve, which in turn will cause a chain reaction such as increased porosity of manufactured sand and changes in water demand, ultimately seriously affecting the key properties of concrete such as workability, strength and durability. Only by achieving precise control of material feeding can the stability and reproducibility of gradation be guaranteed, thereby producing finished sand with highly uniform quality and meeting performance standards.

[0004] Chinese utility model patent CN219745516U discloses a gradation adjustment device for manufactured sand. This utility model can adjust materials of different grades by setting adjustment equipment, while avoiding mixing materials of different sizes together, thus improving the flexibility of the device. However, this device cannot effectively control the weight added when mixing and adjusting manufactured sand. Moreover, most existing technologies rely on detecting the weight of the sand jar and judging the weight of the discharged sand based on the change in the weight of the sand jar. However, it is impossible to accurately discharge sand during the sand jar addition process, resulting in inaccurate proportions and affecting the finished product qualification rate.

The sorting component 1 sorts out manufactured sand of different mesh sizes and transports them to a mixing component 2 to improve the sorting efficiency of manufactured sand. The mixing component 2 collects the sorted manufactured sand and mixes it as needed. The discharge weight is precisely controlled during discharge. When the sorting component 1 is working, the mixing component 2 can also grade the manufactured sand. This invention improves the gradation efficiency of manufactured sand.

[0020] As shown in the sorting components 1-5, the sorting component 1 includes a support base 103, with an mounting ring 104 on the side of the support base 103. A housing 101 is mounted on the upper end of the support base 103, and multiple sets of through holes 105 are provided on the side of the housing 101. A sorting box 110 is housed inside the housing 101, with multiple sets of limiting posts 106 on both sides of the sorting box 110. The limiting posts 106 are slidably connected to the housing 101, and a spring 114 is provided between the limiting posts 106 and the housing 101. A protruding post 115 is provided on one side of the sorting box 110, and the protruding post 115 is slidably connected to the housing 101. A motor 108 is mounted on the side of the housing 101, and a cam 1 is mounted on the output shaft of the motor 108. 07. Cam 107 is rotatably connected to housing 101. Roller 116 is rotatably mounted on protruding column 115. Cam 107 is in contact with roller 116. When motor 108 is started, motor 108 drives cam 107 to rotate. Cam 107 pushes protruding column 115 to move. Protruding column 115 drives sorting box 110 to slide back and forth in housing 101. Sorting box 110 shakes. Feed hopper 102 is provided at the upper end of housing 101. The lower end of feed hopper 102 is connected to the upper end of sorting box 110 through hose 109. The manufactured sand to be sorted is put into feed hopper 102. The manufactured sand enters sorting box 110 through feed hopper 102 and hose 109.

[0021] refer to Figure 5The sorting box 110 shown is equipped with multiple sets of screen plates 112, which are inclinedly arranged inside the sorting box 110. The diameter of the screen holes on the multiple sets of screen plates 112 is different. Multiple discharge ports are arranged on the side of the sorting box 110. The discharge port is located at the lowest end of the screen plate 112. A discharge rack 111 is arranged on the discharge port 1. An electromagnetic control valve is arranged between the discharge rack 111 and the discharge port 1. A discharge port 2 is arranged at the lower end of the sorting box 110. A flexible hose 113 is arranged on the discharge port 2. An electromagnetic control valve is arranged between the flexible hose 113 and the discharge port 2. Second, the screen plates 112 are distributed from top to bottom, and the aperture of the screen plates 112 decreases from top to bottom. When the sorting box 110 shakes, the manufactured sand is sorted by the screen plates 112. The manufactured sand smaller than the diameter of the screen plate 112 falls to the next screen plate 112, while the manufactured sand larger than the diameter of the screen plate 112 remains on the screen plate 112 and gradually enters the discharge rack 111 through the discharge port 1. After passing through the bottom screen plate 112, the manufactured sand accumulates at the bottom of the sorting box 110 and enters the mixing component 2 through the hose 113, thus completing the sorting of the manufactured sand.

[0022] refer to Figure 6 , 7 As shown, the mixing component 2 includes a mixing box 201 and a multi-storage box 202. The mixing box 201 is mounted on the mounting ring 104. A storage box 203 is provided at the upper end of the mixing box 201. The upper end of the storage box 203 is connected to a hose 113. The sorted manufactured sand in the sorting box 110 enters the storage box 203 through the hose 113. A hose 304 is provided at the upper end of the storage box 202. The hose 304 passes through the through hole 105 and is connected to the discharge rack 111. The sorted manufactured sand enters the storage box 202 through the discharge rack 111 and the hose 304. The outer shell 101 is positioned higher than the installation positions of the storage box 202 and the storage box 203. The sorted manufactured sand is transported by gravity to the storage box 203 and the storage box 202 within the hose 213 and the hose 304.

[0023] refer to Figure 8 , 9As shown, a discharge hopper 208 is provided at the lower end of the storage bin 202. The discharge hopper 208 is connected to the mixing box 201. An electromagnetic control valve is provided at the connection between the discharge hopper 208 and the storage bin 202. A weighing plate 209 is also provided inside the discharge hopper 208. The weighing plate 209 weighs the manufactured sand fed into the discharge hopper 208 from the storage bin 202. An electric cylinder 206 is provided on the side of the discharge hopper 208. A pusher plate 205 is provided at the movable end of the electric cylinder 206. The pusher plate 205 is slidably connected to the discharge hopper 208. When the manufactured sand in the discharge hopper 208... When the weight reaches the preset standard, the pusher plate 205 is driven to push the manufactured sand in the discharge hopper 208 into the mixing box 201. A baffle 213 is rotatably installed in the discharge hopper 208. The baffle 213 is controlled by motor 2 to rotate in the discharge hopper 208. When the storage box 202 discharges sand into the discharge hopper 208, the baffle 213 is attached to the side of the weighing plate 209 to prevent the manufactured sand from falling off the weighing plate 209. After weighing is completed, motor 2 is started. Motor 2 drives the baffle 213 to rotate on the discharge hopper 208, and the baffle 213 is released from the attachment to the side of the weighing plate 209.

[0024] refer to Figure 8 As shown in the sorting component 10, an electromagnetic control valve 4 is installed at the connection between the upper end of the mixing box 201 and the storage box 203. A sealing plate 211 is slidably installed inside the mixing box 201. A weighing plate 212 seals the space between the mixing box 201 and the storage box 203. There is a gap between the weighing plate 212 and the mixing box 201 to avoid affecting the weighing effect of the weighing plate 212. The gap between the weighing plate 212 and the mixing box 201 is smaller than the particle size of the manufactured sand in the storage box 203. The sealing plate 211 is equipped with... Weighing plate 212 and mixing box 201 are equipped with electric cylinder 210 on the side. The movable end of electric cylinder 210 is connected to the sealing plate 211. When the electromagnetic control valve 4 at the lower end of storage box 203 is opened, the manufactured sand in storage box 203 falls onto weighing plate 212. When the weight of the manufactured sand on weighing plate 212 reaches the preset value, electric cylinder 210 is activated. Electric cylinder 210 drives the sealing plate 211 to retract into the mixing box 201. At this time, the manufactured sand on weighing plate 212 falls into the mixing box 201.

[0025] When sorting manufactured sand, the manufactured sand is fed into the feed hopper 102 and enters the sorting box 110 through the hose 109. In the initial state, both the electromagnetic control valve 1 and the electromagnetic control valve 2 in the sorting box 110 are closed. After the manufactured sand enters the sorting box 110, the motor 108 is started. The motor 108 drives the cam 107 to rotate. The cam 107 presses the protruding column 115. The protruding column 115 drives the sorting box 110 to slide inside the outer shell 101. The sorting box 110 causes the manufactured sand to shake, so that the screen plate 112 sorts the manufactured sand.

[0026] During the sorting process, electromagnetic control valves 1 and 2 on the sorting box 110 are opened. The sorted manufactured sand enters storage tank 203 and storage tank 1 202 through hose 2 113 and hose 3 204 respectively, completing the collection of the sorted manufactured sand. When the sorting mesh size of the manufactured sand is close, the sorting time needs to be increased. When increasing the sorting time, electromagnetic control valves 1 and 2 on the sorting box 110 are closed to improve the sorting effect of the manufactured sand.

[0027] When it is necessary to transport the manufactured sand in storage bin 202 to mixing bin 201, open the electromagnetic control valve 3 between storage bin 202 and discharge hopper 208, and start motor 2. Motor 2 drives baffle 213 to rotate so that baffle 213 fits against the side of weighing plate 209, blocking the manufactured sand on weighing plate 209 to prevent it from falling and affecting the weighing accuracy. At this time, the manufactured sand in storage bin 202 falls onto weighing plate 209. Weighing plate 209 detects the weight of the manufactured sand. When the preset value is reached, close electromagnetic control valve 3 at the lower end of storage bin 202, and drive baffle 213 to reset. Start electric cylinder 206. Electric cylinder 206 drives pusher plate 205 to move. Pusher plate 205 pushes the manufactured sand in weighing plate 209 and discharge hopper 208 into electric cylinder 210, completing the precise feeding.

[0028] When it is necessary to transport the manufactured sand in storage bin 203 to mixing bin 201 for mixing, open the electromagnetic control valve 4 between storage bin 203 and mixing bin 201. At this time, the manufactured sand in storage bin 203 falls onto weighing plate 212. Weighing plate 212 detects the weight of the manufactured sand. When the weight of the manufactured sand on weighing plate 212 reaches the preset value, start electric cylinder 210. Electric cylinder 210 drives the sealing plate 211 to retract into mixing bin 201. At this time, weighing plate 212 is pushed down into mixing bin 201, completing the precise feeding.

[0029] If a single feeding of material into storage bin 1 (202) or storage bin 2 (203) cannot meet the preset requirements, multiple feedings will be performed.

[0030] During the process of adding manufactured sand, storage bin 1 202 and storage bin 203 can also discharge manufactured sand into mixing box 201 through discharge hopper 208 and closing plate 211 for gradation.

[0031] After the manufactured sand in the mixing box 201 has been proportioned, the electromagnetic control valve 5 at the discharge port 3 at position 207 is opened to discharge the graded manufactured sand in the mixing box 201.
