Description

Technical Field

[0001] The utility model relates to the technical field of gravel sand-making processing equipment, in particular to a gravel sand-making processing equipment. Background Technique

[0002] As an important equipment in building material production, gravel sand-making processing equipment is widely used in fields such as mines, construction, and road construction. Traditional gravel sand-making equipment drives a crushing roller by a motor to crush large gravel into small gravel, and then goes through a series of technological processes such as screening and conveying to break large stones into sand and gravel meeting building requirements. However, with the increasing construction demands and the increasingly strict environmental protection regulations, while the existing gravel sand-making equipment can produce sand and gravel efficiently, there are some obvious defects, especially in dust removal.

[0003] Chinese Patent Publication: A gravel sand-making processing equipment, Patent Publication No.: CN217774251U, this patent "comprises a housing, a partition is arranged inside the housing, a filler opening is formed in the upper part of the partition, and a secondary material opening is formed in the lower part of the partition. An inlet opening is formed at the top of the housing, a feed hopper is arranged at the inlet opening, a crushing mechanism is arranged below the feed hopper, a screen is arranged below the crushing mechanism, a screen baffle is arranged at the lower end of the screen, a material box is arranged on one side of the screen baffle, a connecting plate is arranged on one side of the material box, a rotating mechanism is arranged between the material box and the connecting plate, the connecting plate is connected with a threaded sleeve block, the threaded sleeve block is sleeved on a screw rod, and a feed plate is arranged at the filler opening of the partition".

[0004] Although this equipment can convey unqualified gravel into the material box through an inclined screen, rotate the screw rod to control the upward movement of the material box, the rotating mechanism dumps the gravel in the material box onto the feed plate, and the gravel is secondarily crushed through the feed plate to achieve the secondary crushing treatment of unqualified gravel. However, in the actual gravel sand-making process, this equipment is not equipped with a dust removal mechanism. A large amount of dust will be generated during the gravel crushing and screening processes, especially in a dry environment, and the dust is easy to escape into the air, which not only poses a threat to the health of operators but also causes serious pollution to the surrounding environment. These dust particles are extremely easy to inhale, and workers exposed to the dust environment for a long time may suffer from respiratory diseases. At the same time, the dust will also affect the equipment itself. For example, the dust adhering to the surface of the equipment may cause increased wear of mechanical components, poor operation of the equipment, and even cause the equipment to stop running due to failures, thereby affecting production efficiency. In addition, with the improvement of modern production's environmental protection requirements, equipment that cannot effectively control dust emissions is gradually losing competitiveness in the market. Therefore, how to solve the dust pollution problem while ensuring the efficient operation of gravel sand-making processing equipment has become an important technical problem that urgently needs to be solved in the current industry.

[0008] Preferably, a small gear meshes with the outer wall of the large gear. The small gear is rotatably connected to the side wall of the crushing box. A dust suction pipe is fixedly connected to the side wall of the dust treatment box. The shaft of the small gear penetrates into the interior of the dust suction pipe and is fixedly connected with a dust suction impeller.

[0014] For the gravel sand-making processing equipment, water is conveyed through a water delivery pipe in the dust removal mechanism and then sprayed through a spray head to perform primary dust reduction. The water mist spraying can quickly cover the dust source. By combining the fine water mist particles with the dust in the air, the dust particles are enlarged and accelerated to sink, thereby effectively inhibiting the spread of dust. This reduces the spread of dust to the surrounding environment, concentrates the dust in a local area, and avoids large-area pollution. Especially during the gravel and sand-making processes, spray dust reduction can quickly capture the newly generated dust particles during material crushing and prevent them from spreading into the air. At the same time, the sprayed water mist can be collected and recycled, reducing water resource waste. Then, secondary dust removal is carried out in the dust removal mechanism, enabling the dust suction pipe to collect the residual dust particles, especially fine dust, in the first-stage dust reduction and inhaling them into the dust treatment box. Through further treatment, it ensures that the dust content in the discharged air is significantly reduced, improves the air quality of the workplace, reduces the inhalation of harmful particles by workers, protects the respiratory health of workers, and at the same time, removing dust can significantly reduce the frequency of equipment failures, reduce maintenance costs and unplanned downtime, improve the production efficiency and operation stability of the equipment, and is convenient to use.

[0027] Further, referring to the attached Figures 1 to 6As shown in the figure, the dust removal mechanism includes a large gear 5 rotatably connected to the side wall of the crushing box 1. The shaft output end of the crushing roller 2 penetrates outside the crushing box 1. A belt 6 is sleeved between the shaft of the large gear 5 and the shaft of the crushing roller 2 through a pulley. The shaft of the large gear 5 penetrates the outer wall of the dust treatment box 4 and is fixedly connected to a rotating disk 7. A reciprocating rod 8 is rotatably connected to the outer wall edge of the rotating disk 7. One end of the reciprocating rod 8 is fixedly connected to a piston 9. A piston cylinder 10 is fixedly connected to the side wall of the dust treatment box 4. The piston 9 is slidably connected inside the piston cylinder 10. The outer wall of the piston 9 is closely attached to the inner wall of the piston cylinder 10. A water inlet pipe 11 is fixedly connected to the side wall of the piston cylinder 10. One end of the water inlet pipe 11 penetrates inside the dust treatment box 4. A filter pipe 12 is fixedly connected to the bottom of the piston cylinder 10. One-way valves are respectively arranged at the ends of the water inlet pipe 11 and the filter pipe 12 close to the piston cylinder 10. A plurality of equally spaced and evenly distributed filter meshes 25 are fixedly connected inside the filter pipe 12. The bottom of the filter pipe 12 is threadedly connected to a water delivery pipe 13. One end of the water delivery pipe 13 is threadedly connected to the filter pipe 12, which is convenient for disassembling the filter pipe 12 and cleaning the inside of the filter meshes 25. The output end of the water delivery pipe 13 is fixedly connected to the top of both sides of the crushing box 1. One end of the water delivery pipe 13 extends into the inside of the crushing box 1 and is fixedly connected to a spray head 14. A water return pipe 15 is fixedly connected to the bottom of the crushing box 1. One end of the water return pipe 15 extends into the inner wall of the dust treatment box 4. The outer wall of the large gear 5 meshes with a small gear 16. The small gear 16 is rotatably connected to the side wall of the crushing box 1. A dust suction pipe 17 is fixedly connected to the side wall of the dust treatment box 4. The shaft of the small gear 16 penetrates into the inside of the dust suction pipe 17 and is fixedly connected to a dust suction impeller 18. The output end of the dust suction pipe 17 is fixedly connected to the side wall of the crushing box 1 and is close to the top of the spray head 14. A spray pipe 19 is fixedly connected to the side wall of the water delivery pipe 13. One end of the spray pipe 19 penetrates into the inside of the dust treatment box 4. A screening net 20 and a water separation hole plate 21 are rotatably connected to the middle position of the crushing box 1 close to the bottom of the crushing roller 2. The water separation hole plate 21 is at the bottom of the screening net 20. A fixing plate 22 is fixedly connected to the middle part of the inner wall of the crushing box 1 close to the screening net 20 and the water separation hole plate 21. Expansion springs 23 are fixedly connected to the top and bottom of the fixing plate 22. One end of each expansion spring 23 is fixedly connected to the bottom of the screening net 20 and the top of the water separation hole plate 21 respectively;

[0028] When the dust removal mechanism is in use, first place the crushed stones into the crushing box 1 through the feed inlet. Drive the crushing roller 2 by an external drive source to crush the crushed stones. The crushed blocks after crushing fall to the screening mesh 20 for screening. When the crushed stones fall onto the screening mesh 20, they will squeeze the telescopic spring 23 at one end, thereby vibrating the screening mesh 20 and improving the screening efficiency and discharge speed. The unqualified crushed blocks after screening are discharged from the inside of the crushing box 1 through the discharge port 24. The qualified crushed blocks fall to the water separation hole plate 21 and are discharged from the inside of the crushing box 1 through the discharge port 24 provided on the side wall of the water separation hole plate 21. When the crushed stones fall on the top of the water separation hole plate 21, it will cause the water separation hole plate 21 to vibrate and pull the telescopic spring 23, thereby generating vibration and increasing the discharge speed of the water separation hole plate 21. At this time, dust will be generated when the crushing roller 2 crushes and the screening mesh 20 screens. When the crushing roller 2 rotates, the large gear 5 is driven to rotate by the belt 6 on the shaft of the crushing roller 2. When the large gear 5 rotates, the rotating disk 7 is driven to rotate by the shaft. When the rotating disk 7 rotates, it will drive the reciprocating rod 8 to rotate in a circle. When the reciprocating rod 8 rotates, it will drive the piston 9 to slide up and down in the piston cylinder 10. When the piston 9 slides upward, a negative pressure is generated in the piston cylinder 10, and the water in the dust treatment box 4 will be sucked into the piston cylinder 10. When the piston 9 squeezes the water downward, the one-way valve in the water inlet pipe 11 closes, and at this time the one-way valve in the filter pipe 12 opens, and the water will be squeezed into the filter pipe 12. The water is filtered through multiple filter meshes 25 provided in the filter pipe 12, and the filtered water will be transported to the top of the crushing box 1 through the water delivery pipe 13 and sprayed with water mist through the spray head 14. When the dust-reduced crushed stones fall on the top of the water separation hole plate 21, if there is more water, the water will remain at the bottom of the crushing box 1 and flow back to the dust treatment box 4 through the return pipe 15 for precipitation, so that the water can be recycled. By spraying water mist, it can quickly cover the dust source, and the fine water mist particles are combined with the dust in the air to make the dust particles larger and accelerate their sinking, thereby effectively suppressing the spread of dust. When a small amount of dust still drifts to the feed inlet, the large gear 5 drives the small gear 16 to rotate, increasing the rotation of the small gear 16. When the small gear 16 rotates, it will drive the dust suction impeller 18 to rotate. When the dust suction impeller 18 rotates, it will extract the air at the top of the crushing box 1, and then suck the dust floating on the inner wall of the top of the crushing box 1 into the dust suction pipe 17 and then discharge it onto the water surface in the dust treatment box 4, so that the dust particles adhere to the water surface after the dust contacts the water. At this time, while transporting water through the water delivery pipe 13, water is sprayed on the top of the dust treatment box 4 through the spray pipe 19, thereby reducing the dust in the discharged air again to avoid the spread of dust into the air. Through the dust removal mechanism, water is transported through the water delivery pipe 13 and then sprayed with water mist through the spray head 14, so that it can carry out primary dust reduction. The water mist spraying can quickly cover the dust source, and the fine water mist particles are combined with the dust in the air to make the dust particles larger and accelerate their sinking, thereby effectively suppressing the spread of dust. This reduces the spread of dust to the surrounding environment.The dust is concentrated in a local area, avoiding large-area pollution. Especially during the processes of crushing stones and making sand, spray dust suppression can quickly capture the newly generated dust particles when the materials are broken, preventing them from spreading into the air. Then, secondary dust removal is carried out in the dust removal mechanism, enabling the dust suction pipe 17 to collect the residual dust particles, especially the fine dust, in the first dust suppression, and sucking them into the dust treatment box 4. Through further treatment, it ensures that the dust content in the discharged air is significantly reduced, improving the air quality of the workplace, reducing the inhalation of harmful particles by workers, protecting the respiratory health of workers. At the same time, removing dust can significantly reduce the frequency of equipment failures, lower the maintenance cost and unplanned downtime, improve the production efficiency and operation stability of the equipment, and facilitate use.

[0029] Further, referring to the attached Figure 2 As shown, one end of the telescopic spring 23 connected to the screening mesh 20 and the water diversion hole plate 21 is inclined. A discharge port 24 is fixedly connected to the side wall of the crushing box 1 near the inclined end of the telescopic spring 23 connected to the screening mesh 20 and the water diversion hole plate 21. By the inclined setting of the screening mesh 20 and the water diversion hole plate 21, it is convenient for the crushed stones to roll to the discharge port 24 and be discharged.

[0030] Further, referring to the attached Figure 2 As shown, the bottom shape of the dust treatment box 4 is conical. A sewage discharge pipe 26 is fixedly connected to the bottom of the dust treatment box 4. Through the sewage discharge pipe 26, the impurities at the bottom of the precipitated water are discharged.
