Description

Technical Field

[0001] The invention relates to the technical field of sand making, and in particular to an environmentally friendly and low-energy consumption sand making production device. Background Art

[0002] Traditional sand making methods are usually based on quarries, with large-scale mining of ore and river sand, which has caused great damage to the ecological environment. Green sand making uses advanced production equipment and technology to mine stones from legal mines efficiently and at low cost, reducing damage to the natural environment. Green sand making has played a positive role in promoting environmental protection. Green sand making also focuses on waste treatment and resource reuse. Through scientific and reasonable stone recycling and reuse, it reduces waste emissions and effectively reduces environmental pollution. Green sand making is of great significance to economic development. The sand making industry is one of the basic industries for social construction and industrial production, and plays an important role in promoting national economic development. Green sand making not only achieves the sustainable development of sand and gravel production, but also improves the quality and output of stone, meeting the growing construction needs.

[0003] At present, when the sand washing machine is cleaning, the sand washing bucket rotates, and the sand and gravel enter the sand washing trough from the bottom of the sand washing box. The sand and gravel roll under the sand washing bucket as the sand washing bucket rolls, and grinds each other to remove impurities on the surface of the sand and gravel. At the same time, adding water to the sand washing machine can discharge impurities and foreign matter with small specific gravity from the overflow trough to achieve a cleaning effect. However, the large amount of sand and gravel is easy to accumulate together, which can easily cause the sand and gravel surface at the bottom of the sand washing trough to be unable to fully contact with water, resulting in dust and impurities on the surface of some sand and gravel cannot be cleaned, reducing the cleaning effect, and affecting the bonding effect of sand and gravel with concrete when used. Secondly, in order to improve the quality of sand and gravel cleaning, the sand washing machine needs to be cleaned many times, and a large amount of water resources will be consumed during the cleaning process, and the environmental protection effect is poor. Summary of the invention

[0004] The invention provides an environmentally friendly and low-energy sand making production device, which has the function of turning over the sand and gravel washed in the sand washing trough, so that the sand and gravel accumulated at the bottom of the sand washing trough can be turned out conveniently, and the dead angle of washing can be reduced, and the beneficial effect of sand and gravel cleaning effect can be improved. It solves the problem that when the current sand washing machine is cleaning, the sand washing bucket rotates, and the sand and gravel enter the sand washing trough from the bottom of the sand washing box, and rolls under the sand washing bucket as the sand washing bucket rolls, grinding each other to remove impurities on the surface of the sand and gravel. At the same time, water is added to the sand washing machine to discharge impurities and foreign matter with small specific gravity from the overflow trough to achieve a cleaning effect. However, a large number of sand and gravel are easy to pile up together, which easily causes the sand and gravel surface at the bottom of the sand washing trough to be unable to fully contact with water, resulting in that dust and impurities on the surface of some sand and gravel cannot be cleaned up, reducing the cleaning effect, and affecting the bonding effect of sand and gravel with concrete when used. Secondly, in order to improve the quality of sand and gravel cleaning, the sand washing machine needs to be cleaned multiple times, and a large amount of water resources will be consumed during the cleaning process, and the environmental protection effect is poor.

[0014] A control method for an environmentally friendly, low-energy consumption sand production device comprises the following specific steps: Step 1: Crushing of stone: When making sand, put the stone into the coarse crusher for preliminary crushing, then control the belt conveyor to operate, and convey the produced coarse material to the fine crusher by the belt conveyor for further crushing, reducing the volume of the coarse material to form finely crushed stone; Step 2: Screening of stones: Put the crushed stones into the vibrating screen to screen out the stones that meet the feed size of the sand making machine and the stones that are too large to meet the feed size of the sand making machine. The stones that meet the feed size of the sand making machine enter the sand making machine for sand making, and the other part of the materials are returned for fine crushing; Step 3: Sand making: Control the sand making particle size of the sand making machine, put the stone that meets the feed particle size of the sand making machine into the sand making machine, make the sand and gravel particle size that meets the requirements, pass through the output belt and the sand washing machine to make the finished sand, and the other part is put into the sand making machine for crushing again, and finally produce various sand materials that meet the requirements; Step 4: Sand washing: The sand and gravel that meet the requirements are transported to the sand washing machine through a belt conveyor, and the feed amount and speed of the sand washing machine are controlled according to the motor load rate of the sand washing machine. The sand and gravel are washed to remove impurities on the surface of the sand and gravel to achieve a cleaning effect.

[0015] The present invention has the following beneficial effects: The sand washing machine can also be used to wash the sand and gravel in the sand washing tank, so that the sand and gravel can be cleaned by the washing machine through the washing machine. The crushed and screened sand and gravel are transported to the sand washing box through the main body of the production line to contact with water. Referring to Figure 1, the transmission assembly drives the main shaft on the bearing seat to rotate, and the main shaft drives the sand washing bucket on the rotating frame to rotate, so that the sand and gravel at the bottom of the sand washing box can be shoveled into the sand washing tank of the sand washing bucket. As the sand washing bucket rotates, the mounting bracket sprays multiple nozzles fixed by the mounting plate, so that the sand and gravel in the sand washing tank can be washed. At the same time, the resistance rod slidably connected on the sand washing bucket conflicts with the first resistance block fixed on the mounting bracket, so that the resistance rod drives the first sliding frame and the first strip frame to move horizontally. At the same time, the first spring accumulates force, and several first scrapers under the first strip frame contact the sand and gravel at the bottom of the sand washing tank to turn the material, so that the water sprayed by the nozzle can wash the turned over sand and gravel, and the impurities and dust attached to the surface of the sand and gravel at the bottom of the sand washing tank can flow out of the sand washing bucket from the screen along with the water, which can reduce the cleaning dead angle of sand washing and improve the quality and efficiency of sand washing.

[0016] 2. The environmentally friendly and low-energy sand production device can be fixedly connected with the insertion rod through the mounting block fixed at one end of the connecting rod, so that the rotating block can rotate on the mounting block. Through the cooperation of the rotating block and the resistance component, the first bar frame can resist the bar block when it moves horizontally, so that the resistance component can be telescopically slid on the rotating block under the influence of the resistance force, and can be conveniently engaged in the card slot, so that the first bar frame and the second bar frame can be linked. When the first bar frame moves back and forth, the second bar frame can be pulled to move synchronously, so that the second scraper arranged under the second bar frame can also move with it, so that the second scraper and the first scraper can both turn over the sand and gravel on one side of the sand washing tank, so as to further improve the effect of sand and gravel cleaning; When the first spring releases its elastic force to drive the first bar frame to reset, the bar block is resisted by the resistance assembly, thereby pulling the connecting rod to move horizontally, and at the same time, the second bar frame connected to the other end of the connecting rod and a plurality of second scrapers arranged under the second bar frame can also move synchronously. The third spring accumulates force at the same time, and the second scraper moves to facilitate the turning over of the sand and gravel in the sand washing trough, thereby increasing the contact area of ​​sand and gravel washing and reducing the dead angle of washing. When the rotating block is detached from the guide rod, the rotating block overcomes the resistance of the torsion spring and deflects. As the rotating block deflects, the bar block and the resistance component are staggered, thereby releasing the limit, and the third spring releases the elastic force at the same time, which can prompt the second bar frame to reset, and during the resetting process, the second scraper can be prompted to turn over the sand and gravel again, further improving the cleaning effect of the sand and gravel. At the same time, the first scraper connected to the first bar frame and the second scraper connected to the second bar frame are linked in sections, which can reduce the size of the equipment and facilitate use. At the same time, the sand and gravel in the sand washing trough can be cleaned. The cleaning quality and efficiency can be improved, the use of water resources can be reduced, which is beneficial to improving environmental protection and reducing the energy consumption of sand making.

[0017] 3. The environmentally friendly and low-energy sand production device can pull the first sliding frame and the second sliding frame to move during the material turning process when the first sliding frame fixed at the end of the resistance rod slides in the first bar frame and the second sliding frame fixed at the end of the connecting rod slides in the second bar frame, and can simultaneously drive a plurality of resistance bars to respectively conflict with the third resistance blocks in the first sliding frame and the second sliding frame. During the movement of the plurality of third resistance blocks, a plurality of first scrapers can be respectively driven to slide in the slide groove of the first sliding frame and a plurality of second scrapers can be respectively driven to slide in the slide groove of the second sliding frame, thereby changing the working positions of the first scraper and the second scraper, increasing the amplitude of the material turning and improving the flushing effect of the sand and gravel inside the sand washing trough.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0030] See also Figure 1-Figure 10An environmentally friendly and low-energy sand production device comprises a production line body 1 and a sand washing box 2 arranged at one end of the production line body 1, bearing seats 3 are fixed on both sides of the sand washing box 2, and a main shaft 4 is rotatably connected to the bearing seat 3, two rotating frames 5 are fixed on the main shaft 4, and a sand washing hopper 6 is fixed on the rotating frame 5, and a plurality of sand washing tanks 7 are arranged in the sand washing hopper 6, a transmission component for driving the main shaft 4 to rotate is fixed on the sand washing box 2, and a screen 33 is fixed on the sand washing hopper 6; Two mounting brackets 8 are fixed on the sand washing box 2, and the two mounting brackets 8 are fixed with a first resistance block 9, a mounting plate 10 is fixed on the top of the mounting bracket 8, a plurality of nozzles 11 are fixed on the mounting plate 10, a plurality of resistance rods 12 are slidably connected to the sand washing hopper 6, and the resistance rods 12 are elastically connected to the sand washing hopper 6 through a first spring 121, a plurality of first scrapers 13 are arranged in the sand washing trough 7, a first sliding frame 15 is fixed on one side of the resistance rod 12, a first strip frame 14 is slidably connected to the first sliding frame 15, and the first scraper 13 is connected to the first strip frame 14.

[0031] The transmission assembly includes a servo motor 41, a reducer 42 and a mounting seat 43. The mounting seat 43 is fixed on the sand washing box 2, the reducer 42 is fixed on the mounting seat 43, and the output end of the reducer 42 is connected to the main shaft 4 through a coupling. The servo motor 41 is fixed on the mounting seat 43, and the motor shaft of the servo motor 41 is connected to the input end of the reducer 42 through a coupling.

[0032] During sand washing, the crushed and screened sand and gravel are transported to the sand washing box 2 through the production line body 1 to contact with water. When the reducer 42 fixed on the mounting seat 43 is connected to the servo motor 41, the speed of the servo motor 41 can be reduced through the reducer 42, and the output torque of the reducer 42 can be increased, thereby driving the main shaft 4 on the bearing seat 3 to rotate. The main shaft 4 drives the sand washing bucket 6 on the rotating frame 5 to rotate, and the sand and gravel can be shoveled into several sand washing troughs 7 of the sand washing bucket 6. As the sand washing bucket 6 rotates, the mounting bracket 8 is connected to the water pipe through multiple nozzles 11 fixed by the mounting plate 10, so that water can be sprayed out. The sprayed water can wash the surface of the sand and gravel in the sand washing trough 7. At the same time as the sand washing bucket 6 rotates When the sand washing trough 7 is turned over, the water sprayed by the nozzle 11 can rinse the turned over sand and gravel, so that impurities and dust attached to the surface of sand and gravel at the bottom of the sand washing trough 7 can flow out of the sand washing trough 6 from the screen 33 along with the water, thereby reducing the cleaning dead angle of sand washing and improving the quality and efficiency of sand washing. Example 2

[0033] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 10 A partition 16 is fixed in the sand washing tank 7, a connecting rod 17 is slidably connected to the partition 16, a second sliding frame 18 is fixed to one end of the connecting rod 17, a second strip frame 19 is slidably connected to the second sliding frame 18, and a plurality of second scrapers 20 are arranged below the second strip frame 19.

[0034] A mounting block 21 is fixed to the end of the connecting rod 17, and an insertion rod 22 is fixed on the mounting block 21, a rotating block 23 is inserted on the insertion rod 22, the insertion rod 22 is elastically connected to the rotating block 23 through a torsion spring 24, and an abutment assembly is connected to the upper end of the rotating block 23. A strip block 25 is fixed to the first strip frame 14, and a slot 26 is provided on the strip block 25. The second strip frame 19 is elastically connected to the side wall of the sand washing tank 7 through a third spring 191.

[0035] A guide rod 27 is fixed on the partition plate 16 , and an insertion hole 28 is provided on the rotating block 23 and the first bar frame 14 , and the insertion hole 28 is matched with the guide rod 27 .

[0036] The resisting assembly includes a second resisting block 231 , which is slidably connected to the rotating block 23 , and the second resisting block 231 is elastically connected to the rotating block 23 via a fourth spring 232 .

[0037] refer to Figure 3-Figure 9The resistance rod 12 slidably connected on the sand washing hopper 6 resists against the first resistance block 9 fixed on the mounting bracket 8, thereby pushing the first bar frame 14 to move. When the first bar frame 14 moves horizontally, it can drive the bar block 25 to gradually approach the second resistance block 231 on the rotating block 23. When the second resistance block 23 is continuously affected by the resistance force, the second resistance block 23 shrinks in the rotating block 23. At the same time, the fourth spring 232 accumulates force. When the first bar frame 14 drives the first scraper 13 to move and turn the sand and gravel, the second resistance block 23 shrinks downward under the influence of the resistance force and can slide into the slot 26 of the bar block 25. At the same time, under the action of the fourth spring 232, the second resistance block 23 can be firmly pressed in the slot 26. The guide rod 27 fixed on the partition 16 is inserted into the insertion hole 28 opened on the rotating block 23 and the first bar frame 14, so that the direction of the rotating block 23 is limited when it slides on the guide rod 27 for a distance, so as to avoid being affected by the resistance of sand and stones, causing the rotating block 23 to rotate, and the second contact block 23 to disengage from the slot 26 of the bar block 25. When the first spring 121 releases the elastic force to drive the first bar frame 14 to reset, the bar block 25 is affected by the limit of the second contact block 23, thereby pulling the connecting rod 17 to move horizontally and smoothly. At the same time, the second bar frame 19 connected to the other end of the connecting rod 17 and the plurality of second scrapers 20 arranged under the second bar frame 19 can also move synchronously. At the same time, the third spring 191 accumulates force, and the second scraper 20 moves conveniently to The sand and gravel in the sand washing trough 7 are turned over to increase the contact area of ​​the sand and gravel for washing and reduce the dead angle of washing. When the rotating block 23 is separated from the guide rod 27, as the rotating block 23 continues to move, the torsion spring 24 is deformed, and the rotating block 23 overcomes the resistance of the torsion spring 24 and deflects, which can achieve the purpose of reducing the position angle of the rotating block 23. As the displacement increases, the third spring 191 can no longer be compressed. At this time, the rotating block 23 and the connecting rod 17 stop moving. As the rotating block 23 deflects, the second resistance block 231 is staggered with the strip block 25, thereby disengaging from the slot 26. At this time, the second strip frame 19 returns to its original position driven by the third spring 191. When the second strip frame 19 is reset, it can drive the second scraper 20 to turn over the sand and gravel again. To further improve the cleaning effect of sand and gravel, since the moving distance of the first bar frame 14 will be affected by the length of the resistance rod 12, if the first bar frame 14 moves in the entire sand washing trough 7 to drive the first scraper 13 to turn over the material, the working length of the resistance rod 12 will be longer. Since the resistance rod 12 needs to rotate with the sand washing hopper 6, the volume of the equipment will be increased. On the one hand, it is inconvenient to move the equipment, and on the other hand, the working efficiency is low and the manufacturing cost is high. When the first scraper 13 connected by the first bar frame 14 and the second scraper 20 connected by the second bar frame 19 are linked in sections, there is no need to extend the length of the resistance rod 12. At the same time, it can meet the purpose of turning over the sand and gravel in the sand washing trough 7. At the same time, the sand and gravel in the sand washing trough 7 can be improved in cleaning quality and efficiency.It can reduce the use of water resources, which is beneficial to improving environmental protection and reducing the energy consumption of sand making. Example 3

[0038] This embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 10 A plurality of third resistance blocks 29 are provided in the first bar frame 14 and the second bar frame 19, and the plurality of third resistance blocks 29 are elastically connected to the first bar frame 14 and the second bar frame 19 respectively through a fifth spring 30, and a plurality of resistance bars 31 are fixed on the first sliding frame 15 and the second sliding frame 18, and the resistance bars 31 resist the third resistance blocks 29.

[0039] A plurality of slide grooves 32 are provided on the first bar frame 14 and the second bar frame 19 . The second scraper 20 and the first scraper 13 are slidably connected in the slide grooves 32 . A plurality of third abutment blocks 29 are fixedly connected to the second scraper 20 and the first scraper 13 .

[0040] A protective cover plate 34 is fixed on the surface of the first bar frame 14 and the second bar frame 19 .

[0041] In order to improve the sand and gravel turning effect in the sand washing tank 7, refer to Figure 4-Figure 8 When the first sliding frame 15 fixed at the end of the resistance rod 12 slides in the first bar frame 14, and the second sliding frame 18 fixed at the end of the connecting rod 17 slides in the second bar frame 19, the first sliding frame 15 and the second sliding frame 18 can be pulled to move synchronously during the material turning process, which can drive the resistance bar 31 fixed on the first sliding frame 15 to conflict with the third resistance block 29 in the first bar frame 14, and the resistance bar 31 fixed on the second sliding frame 18 to conflict with the third resistance block 29 in the second bar frame 19. During the movement, several first scrapers 13 and second scrapers 20 can be driven to slide in the slide groove 32 respectively, thereby changing the working positions of the first scraper 13 and the second scraper 20, increasing the amplitude of material turning, and improving the flushing effect of sand and gravel inside the sand washing trough 7. Example 4
