Description

Technical Field

[0001] The invention relates to the technical field of crushing devices, and in particular to a waste concrete crushing device. Background Art

[0002] As an important building material, concrete consumes a lot of natural resources, such as sand, gravel, cement, etc. in its preparation process. By recycling waste concrete and classifying it, the classified waste concrete is crushed into smaller pieces, and then these pieces are graded according to different particle sizes through screening equipment. This process can obtain aggregates of different particle sizes to meet different reuse needs and be used to produce new concrete or other building materials. This not only saves the exploitation of natural resources, but also reduces the accumulation of construction waste and realizes the recycling of resources.

[0003] The patent document with application number 202222697884.3 discloses a waste concrete crushing device, which belongs to the field of waste concrete processing technology. It includes a processing box and a cover body. The upper surface of the cover body is fixedly connected to a feed port, and the inner wall of the processing box is rotatably connected to two sets of rotating shafts through bearings.

[0004] A lot of dust will be generated when waste concrete is crushed, which not only threatens the health of operators, but also may pollute the environment. However, some traditional waste concrete crushing devices humidify the waste concrete before crushing for wet crushing, while others add an appropriate amount of water during the crushing process to crush the concrete in a wet state, thereby reducing the generation of dust. However, these two methods will not only waste a lot of water resources, but also make the waste concrete too wet, and the water content of the concrete needs to be reduced by drying or drying, which wastes resources and affects the overall production efficiency. Summary of the invention

[0005] The present invention discloses a waste concrete crushing device, which aims to solve the technical problem that some waste concrete crushing devices humidify the waste concrete before crushing to perform wet crushing, while some add a proper amount of water during the crushing process to crush the concrete in a wet state, thereby reducing the generation of dust, but these two methods not only waste a large amount of water resources, but also make the waste concrete too wet, and the water content of the concrete needs to be reduced by methods such as drying or drying, which wastes resources and affects the overall production efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A waste concrete crushing device comprises a body and a feed port and a discharge port respectively arranged on the top outer wall and the bottom outer wall of the body, wherein the inner wall of the body is also provided with a crushing assembly, and further comprises:

[0008] A dust suction mechanism, the dust suction mechanism is arranged on an outer wall of one side of the body, the dust suction mechanism includes an opening opened on the inner wall of one side of the body, an outer wall of one side of the body is connected to an air intake hopper and a water tank, a water ring is installed on the inner wall of the air intake hopper, and the outer wall of the water ring is provided with atomizing nozzles distributed at equal distances, an outer wall of one side of the water ring is connected to a water inlet pipe, an outer wall of one side of the air intake hopper is connected to a first installation cylinder, a bottom inner wall of the first installation cylinder and a side of the top outer wall of the water tank away from the air intake hopper are both provided with a plurality of corresponding drainage ports, an inner wall of one side of the first installation cylinder is connected to a separation cylinder, and the separation cylinder The inner wall of the separation cylinder is provided with water outlet grooves distributed at equal distances, a second installation cylinder is installed on the outer wall of one side of the separation cylinder, and both sides of the inner wall of the second installation cylinder are connected to a plurality of stator blades distributed at equal distances, and one end of the plurality of stator blades located on both sides of the inner wall of the second installation cylinder is respectively connected to a first fixed block and a second fixed block, a rotating block is connected between the first fixed block and the second fixed block through a bearing, and a plurality of rotor blades distributed at equal distances are installed on the circumferential outer wall of the rotating block, and a blade seat is connected to the outer wall of one side of the first fixed block through a bearing, and turbine blades with equal distances are connected to the outer wall of the blade seat;

[0009] A power mechanism, the power mechanism is located on the first mounting tube and the first fixed block, the power mechanism includes a motor installed on the top outer wall of the first mounting tube, the output end of the motor is connected to a rotating rod through a coupling, the bottom end of the rotating rod passes through the first mounting tube and the first fixed block and is connected to a first bevel gear, a cavity is opened inside the first fixed block, a first connecting rod and a second connecting rod are connected inside the first fixed block through a bearing, and the first connecting rod and the second connecting rod are connected to the second bevel gear at opposite ends;

[0010] An auxiliary dust removal mechanism, the auxiliary dust removal mechanism is arranged on the outer wall of the machine body;

[0011] A filter and flushing mechanism, wherein the filter and flushing mechanism is located on the water tank;

[0012] A closing mechanism is installed on the inner wall of the feed port and the inner wall of the discharge port.

[0013] In this solution, the motor, the first bevel gear and the second bevel gear are used to drive the turbine blades and the rotor blades to rotate to extract the dust generated when the waste concrete is crushed. At the same time, the atomizing nozzle is used to spray water mist. With the help of the spiral airflow formed by the turbine blades, the dust in the air is combined with the water mist and settled. Most of the heavier water is pushed to the bypass area between the first mounting cylinder and the second mounting cylinder under the action of the centrifugal force generated by the high-speed rotation of the turbine blades, and finally flows into the water tank under the push of wind force. The remaining small part of the water enters the second mounting cylinder with the humid airflow, and the airflow spirals again through the rotor blades. Under the action of centrifugation, the remaining water is drained through the water outlet trough at the separation cylinder, and then flows into the water tank. Finally, the airflow containing water vapor is naturally discharged. Compared with the traditional dust removal method, this method can effectively save water while ensuring the drying of the waste concrete, eliminating the drying or drying process, which can not only save resources but also improve the overall production efficiency.

[0014] In a preferred embodiment, the auxiliary dust removal mechanism includes a hollow ring installed on the outer wall of the body, and a number of corresponding air inlet holes are opened on the outer walls on both sides of the hollow ring and the inner walls on both sides of the body. A connecting tube is installed on the outer wall of the first mounting tube close to the separation tube, and the bottom outer wall of the connecting tube is connected to an air pipe, and a connecting pipe is installed between the air pipe and the hollow ring.

[0015] During the waste concrete crushing and unloading process, a small amount of dust will still be generated due to collision. The hollow ring is connected to the air pipe. The pressure difference generated by the high-speed airflow containing water vapor discharged from the second mounting cylinder is used to make the air at the bottom of the body flow toward the air pipe, thereby extracting a small amount of dust generated during the concrete unloading process. The dust is mixed with the airflow containing water vapor and finally discharged, avoiding dust overflow and scattering everywhere, while improving the utilization rate of resources.

[0016] In a preferred embodiment, the filtering and flushing mechanism includes a protrusion installed on the bottom outer wall of the water tank, a filter cartridge is inserted into the bottom outer wall of the water tank, the bottom end of the filter cartridge is connected to a threaded cylinder, the bottom end of the threaded cylinder is connected to a water pipe, the outer wall of the water pipe is provided with a first valve, one side outer wall of the hollow ring is connected to a water outlet pipe, the outer wall of the water outlet pipe is provided with a second valve, and the inner wall of the protrusion is also provided with an adjustment hole.

[0017] After the crushing work is completed, open the first valve and the second valve, and discharge the water stored in the water tank into the hollow ring through the water pipe to flush the inside of the hollow ring. This not only makes secondary use of water resources, but also ensures the smooth flow of the hollow ring to avoid clogging due to dust, thereby ensuring its long-term normal operation. The filter cartridge can filter the dust particles precipitated in the water tank. At the same time, the filter cartridge is installed at the bottom of the water tank through a threaded cylinder, which is convenient for disassembly and can be cleaned regularly.

[0018] In a preferred embodiment, the closing mechanism comprises a plurality of equally spaced partition curtains installed on the top inner wall of the feed port and the top inner wall of the discharge port, the bottom ends of the plurality of partition curtains are connected to iron blocks, and the plurality of partition curtains are arranged in a front-to-back staggered structure, and the lengths of the partition curtains and the iron blocks are adapted to the heights of the feed port and the discharge port.

[0019] In order to further prevent a small amount of dust from overflowing from the machine body, partition curtains and iron blocks are added to the feed port and the discharge port. The partition curtains are used to keep the machine body in a relatively closed state when no material is being fed or discharged, thereby preventing a small amount of dust from overflowing during feeding and discharging, and further improving the dust removal effect.

[0020] It can be seen from the above that the waste concrete crushing device provided by the present invention has the technical effect of saving resources and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The waste concrete crushing device disclosed in the present invention is mainly applied to traditional waste concrete crushing devices. Some of them humidify the waste concrete before crushing to perform wet crushing, and some add a proper amount of water during the crushing process to crush the concrete in a wet state, thereby reducing the generation of dust. However, these two methods not only waste a large amount of water resources, but also make the waste concrete too wet, and the water content of the concrete needs to be reduced by drying or drying, which wastes resources and affects the overall production efficiency.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A waste concrete crushing device comprises a body 1 and a feed port 2 and a discharge port 12 respectively arranged on the top outer wall and the bottom outer wall of the body 1, and a crushing assembly 9 is also arranged on the inner wall of the body 1, and further comprises:

[0036] A dust suction mechanism is arranged on an outer wall of one side of the machine body 1. The dust suction mechanism includes an opening 10 opened on the inner wall of one side of the machine body 1. An air inlet hopper 3 and a water tank 34 are highly connected to the outer wall of one side of the machine body 1. A water ring 17 is fixedly installed on the inner wall of the air inlet hopper 3. An atomizing nozzle 18 distributed at equal distances is fixedly installed on the outer wall of the water ring 17. An outer wall of one side of the water ring 17 is fixedly connected to a water inlet pipe 4. A first mounting cylinder 5 is fixedly connected to the outer wall of one side of the air inlet hopper 3. A plurality of corresponding drain ports 21 are opened on the bottom inner wall of the first mounting cylinder 5 and the top outer wall of the water tank 34 away from the air inlet hopper 3. A separation cylinder 20 is fixedly connected to the inner wall of one side of the first mounting cylinder 5. The inner wall of the separation cylinder 20 is opened at equal distances. A water outlet trough 37 is distributed, a second mounting cylinder 19 is fixedly installed on the outer wall of one side of the separation cylinder 20, and a plurality of stator blades 27 distributed at equal distances are fixedly connected to both sides of the inner wall of the second mounting cylinder 19, and one end of the plurality of stator blades 27 located on both sides of the inner wall of the second mounting cylinder 19 is respectively fixedly connected to a first fixed block 24 and a second fixed block 41, and a rotating block 26 is movably connected between the first fixed block 24 and the second fixed block 41 through a bearing, and a plurality of rotor blades 28 distributed at equal distances are fixedly installed on the circumferential outer wall of the rotating block 26, and a blade seat 22 is connected to the outer wall of the blade seat 22 through a movable bearing, and a turbine blade 23 distributed at equal distances is fixedly connected to the outer wall of the blade seat 22;

[0037] The power mechanism is located on the first mounting tube 5 and the first fixed block 24. The power mechanism includes a motor 11 fixedly mounted on the top outer wall of the first mounting tube 5. The output end of the motor 11 is fixedly connected to a rotating rod 29 through a coupling. The bottom end of the rotating rod 29 passes through the first mounting tube 5 and the first fixed block 24 and is fixedly connected to a first bevel gear 30. A cavity is opened inside the first fixed block 24. A first connecting rod 32 and a second connecting rod 33 are movably connected inside the first fixed block 24 through a bearing. The first connecting rod 32 and the second connecting rod 33 are fixedly connected to the second bevel gear 31 at opposite ends.

[0038] Auxiliary dust removal mechanism, the auxiliary dust removal mechanism is arranged on the outer wall of the machine body 1;

[0039] A filter flushing mechanism, the filter flushing mechanism is located on the water tank 34;

[0040] A closing mechanism, the closing mechanism is installed on the inner wall of the feed port 2 and the inner wall of the discharge port 12;

[0041] One end of the first connecting rod 32 away from the second bevel gear 31 is fixedly connected to the blade seat 22, the rotating block 26 is fixedly connected to the second connecting rod 33, the second fixed block 41 is movably connected to the second connecting rod 33 through a bearing, the first bevel gear 30 and the second bevel gear 31 are both located inside the cavity, and the water tank 34 is fixedly connected to the first mounting cylinder 5.

[0042] Among them, the turbine blades 23, the stator blades 27 and the rotor blades 28 are all arranged in a spiral structure, and the spiral directions of the stator blades 27 and the rotor blades 28 are opposite, the stator blades 27 and the turbine blades 23 have the same spiral direction, the stator blades 27 are fixed, and play the role of fixing the first fixed block 24 and the second fixed block 41, etc. The design of the separate stator blades 27 can ensure that the air flow remains orderly when passing through, reducing turbulence and energy loss, and the rotor blades 28 can compress the air by rotating, and the stator blades 27 and the rotor blades 28 work together to squeeze the air and increase the airflow rate.

[0043] Among them, the blade seat 22, the first fixed block 24, the rotating block 26 and the second fixed block 41 are jointly arranged as a bullet-shaped structure, which helps to reduce the resistance of air flow and avoid excessive turbulence, thereby improving the air intake efficiency. The second mounting cylinder 19 is arranged as an arc-shaped concave structure to form a "narrow tube effect" to increase the wind speed. The opening 10, the air intake scoop 3 and the separation cylinder 20 are all arranged as a truncated cone structure. The opening 10 and the air intake scoop 3 are conducive to air intake.

[0044] It should be noted that one end of the water inlet pipe 4 is connected to a water supply device (this structure is not shown), and the dust suction mechanism is located above the crushing assembly 9, and is mainly used for dust removal during crushing and feeding.

[0045] During specific use, the motor 11 drives the first bevel gear 30 to rotate through the rotating rod 29, and the first bevel gear 30 drives the two second bevel gears 31 to rotate, and then drives the turbine blades 23 and the rotor blades 28 to rotate through the first connecting rod 32 and the second connecting rod 33. The turbine blades 23 rotate to extract dust generated when the waste concrete is crushed, and water enters the water ring 17 from the water inlet pipe 4 and sprays water mist inward through the atomizing nozzle 18. At the same time, with the help of the spiral airflow formed by the turbine blades 23, the dust in the air is combined with the water mist and settled down, and most of the heavier water is pushed to the first connecting rod 23 under the centrifugal force generated by the high-speed rotation of the turbine blades 23. The bypass area between the mounting cylinder 5 and the second mounting cylinder 19 continues to flow into the water tank 34 through the drain port 21 under the push of wind for storage. The remaining small part of moisture enters the second mounting cylinder 19 with the humid airflow. The airflow first passes through a separate stator blade 27 to maintain order, reduce turbulence and energy loss, and then forms a "narrow tube effect" through the second mounting cylinder 19. Under the joint action of the stator blades 27 and the rotor blades 28, the air is squeezed and the airflow velocity increases. Subsequently, with the help of the separation cylinder 20, the remaining moisture is drained through the water outlet trough 37 under the action of centrifugation, and then flows into the water tank 34. Finally, the humid airflow containing water vapor is naturally discharged.

[0046] Reference Figure 1 , Figure 3 and Fig.11In a preferred embodiment, the auxiliary dust removal mechanism includes a hollow ring 8 fixedly mounted on the outer wall of the body 1, and a number of corresponding air inlet holes 14 are opened on the outer walls on both sides of the hollow ring 8 and the inner walls on both sides of the body 1. A connecting tube 6 is fixedly mounted on the outer wall of one side of the first mounting tube 5 close to the separation tube 20, and the position of the connecting tube 6 corresponds to that of the separation tube 20. An air pipe 7 is fixedly connected to the bottom outer wall of the connecting tube 6, and a connecting pipe is fixedly mounted between the air pipe 7 and the hollow ring 8.

[0047] It should be noted that the hollow ring 8 is located below the crushing assembly 9 and is mainly used for dust removal during discharging.

[0048] Specifically, after the concrete is crushed, it falls to the bottom of the machine body 1. During the falling process, a small amount of dust will be generated due to collision. The hollow ring 8 is connected to the air pipe 7 through a connecting pipe. The high-speed airflow containing water vapor discharged from the second mounting cylinder 19 flows through the connecting pipe. The high-speed airflow has a fast flow rate and a low pressure, so that the air at the bottom of the machine body 1 flows toward the air pipe 7 through the air inlet 14, and a small amount of dust generated during the concrete feeding process is extracted. The dust is mixed with the humid airflow containing water vapor and finally discharged, thereby preventing dust from overflowing and scattering everywhere, and at the same time improving the utilization rate of resources.

[0049] Reference Figure 1 , Figure 3 and Fig. 9 In a preferred embodiment, the filtering and flushing mechanism includes a protrusion fixedly mounted on the bottom outer wall of the water tank 34, a filter cartridge 36 is inserted into the bottom outer wall of the water tank 34, a threaded cylinder 35 is fixedly connected to the bottom end of the filter cartridge 36, a water pipe 13 is fixedly connected to the bottom end of the threaded cylinder 35, a first valve 38 is provided on the outer wall of the water pipe 13, a water outlet pipe 15 is fixedly connected to the outer wall of one side of the hollow ring 8, a second valve 16 is provided on the outer wall of the water outlet pipe 15, an adjusting hole is also provided on the inner wall of the protrusion, the bottom end of the water pipe 13 is fixedly connected to the top outer wall of the hollow ring 8, and the protrusion is threadedly connected to the threaded cylinder 35 through the adjusting hole.

[0050] The hollow ring 8 is configured as an inclined structure, and the inclination direction is downward from the water delivery pipe 13 to the water outlet pipe 15 , so that the water entering the hollow ring 8 can be discharged from the water outlet pipe 15 .

[0051] It should be noted that a guide pipe (this structure is not shown) is provided at the highest water level of the water tank 34. When the water tank 34 is almost full, the water in the water tank 34 can be discharged. At the same time, the water tank 34 can be installed with different capacities according to needs.

[0052] Specifically, during crushing, the first valve 38 and the second valve 16 are in a closed state. After the crushing work is completed, the first valve 38 and the second valve 16 are opened, and the water stored in the water tank 34 is filtered through the filter cartridge 36 and then discharged into the hollow ring 8 through the water pipe 13. The interior of the hollow ring 8 is flushed using the height difference. Most of the water is discharged from the water outlet pipe 15 and the air pipe 7, and a small amount of water is discharged from the air inlet 14. After flushing, the first valve 38 and the second valve 16 are closed, which not only makes secondary use of water resources, but also ensures the smooth flow inside the hollow ring 8 to avoid clogging due to dust. After long-term use, the threaded cylinder 35 can be loosened to take out the filter cartridge 36, and the dust particles on the filter cartridge 36 can be cleaned to ensure its long-term operation.

[0053] Reference Figure 1 and Fig.10 In a preferred embodiment, the closing mechanism includes a plurality of equally spaced partition curtains 39 fixedly mounted on the top inner wall of the feed port 2 and the top inner wall of the discharge port 12, and the bottom ends of the plurality of partition curtains 39 are fixedly connected with iron blocks 40.

[0054] Among them, several partition curtains 39 are arranged in a front-to-back staggered structure. The lengths of the partition curtains 39 and the iron blocks 40 are adapted to the heights of the feed port 2 and the discharge port 12. The front-to-back staggered partition curtains 39 can improve the sealing effect. At the same time, the partition curtains 39 are made of transparent rubber material, which is durable, not easy to absorb dust, and has a good dust-blocking effect. It is also convenient to observe the internal situation of the machine body 1.

[0055] After the waste concrete is fed in and discharged, under the gravity of the iron block 40 , the partition curtains 39 naturally droop, interlaced with each other front and back, and sealed the machine body 1 , further preventing a small amount of dust from overflowing from the machine body 1 .

[0056] Working principle: When in use, the first valve 38 and the second valve 16 are in a closed state during crushing, the motor 11 drives the first bevel gear 30 to rotate through the rotating rod 29, the first bevel gear 30 drives the two second bevel gears 31 to rotate, and then drives the turbine blades 23 and the rotor blades 28 to rotate through the first connecting rod 32 and the second connecting rod 33. The turbine blades 23 rotate to extract the dust generated when the waste concrete is crushed, and water enters the water ring 17 from the water inlet pipe 4 and sprays water mist inward through the atomizing nozzle 18. At the same time, with the help of the spiral airflow formed by the turbine blades 23, the dust in the air is removed. The dust combines with the water mist and settles down, while most of the heavier water is pushed to the bypass area between the first installation cylinder 5 and the second installation cylinder 19 under the centrifugal force generated by the high-speed rotation of the turbine blades 23, and continues to flow into the water tank 34 through the drain port 21 under the push of wind force for storage. The remaining small part of the water enters the second installation cylinder 19 with the humid airflow. The airflow first passes through the separate stator blades 27 to maintain order, reduce turbulence and energy loss, and then passes through the second installation cylinder 19 to form a "narrow pipe effect", and under the joint action of the stator blades 27 and the rotor blades 28, the airflow is discharged from the second installation cylinder 19. , the air is squeezed, the air velocity increases, and then with the help of the separation cylinder 20, the remaining water is drained through the water outlet trough 37 under the action of centrifugation, and then flows into the water tank 34. The high-speed airflow containing water vapor discharged by the second installation cylinder 19 flows through the connecting pipe. The high-speed airflow has a fast flow rate and a low pressure, so that the air at the bottom of the body 1 flows through the air inlet 14 to the air pipe 7, extracting a small amount of dust generated during the concrete feeding process. The dust is mixed with the humid airflow containing water vapor and finally discharged. After the crushing work is completed, the first valve 38 and the second valve 16 are opened to store the water in the water tank 34. The water is filtered by the filter cartridge 36 and discharged into the hollow ring 8 through the water pipe 13. The inside of the hollow ring 8 is flushed by utilizing the height difference. Most of the water is discharged from the water outlet pipe 15 and the air pipe 7, and a small amount of water is discharged from the air inlet 14. After the flushing is completed, the first valve 38 and the second valve 16 are closed. At the same time, after the waste concrete is fed and discharged, under the gravity of the iron block 40, the partition curtain 39 naturally droops, interlaced with each other front and back, and the machine body 1 is closed. After long-term use, the threaded cylinder 35 can be unscrewed to take out the filter cartridge 36, and the dust particles on the filter cartridge 36 can be cleaned to ensure its long-term operation.
