Description

Technical Field

[0001] The invention relates to the technical field of material crushing, in particular to a cone crusher capable of protecting a crushing cavity for construction waste. Background Art

[0002] Existing crushers are mechanical equipment that can crush construction waste, bricks, concrete blocks, and stones. They play an important role in the recycling and reuse of construction waste by crushing the waste into suitable particle sizes so that these materials can be reused in the construction industry or other related fields. In the Chinese patent with patent announcement number CN104437726B, a cone crusher is disclosed, including: a frame, and a transmission mechanism, an eccentric mechanism, a hydraulic lifting mechanism, a movable cone spindle group and a support assembly arranged in the frame. The eccentric mechanism is connected to the transmission mechanism, the movable cone main shaft group is positioned and installed in the eccentric mechanism, the hydraulic lifting mechanism is located below the movable cone main shaft group, the hydraulic lifting mechanism and the movable cone main shaft group are connected through a supporting assembly, the frame includes a lower frame and an upper frame, the lower frame is provided with a discharge port, and the upper frame is provided with a feed port; by enlarging the size of the feed port and the discharge port, the stone flow rate of the cone crusher is increased, and the crushing efficiency of the cone crusher is improved; however, the equipment and prior art in the above-mentioned comparative documents still have the following defects when used specifically: 1. Compared with the above-mentioned comparative documents, enlarging the feed port and the discharge port means that more stones can enter the crushing chamber at the same time. However, the design of the crushing chamber, specifically, the gap between the moving cone and the fixed cone, the shape and size of the crushing chamber, have not been optimized accordingly. Therefore, too much stone input will lead to insufficient crushing, that is, the stone is discharged without being sufficiently crushed, thereby affecting the crushing effect; and when the feed volume is too large, the stones in the crushing chamber will accumulate too much, resulting in blockage, especially when targeted treatment of construction waste, the stones contain large pieces or materials with high hardness, and these materials are irregular or sharp in shape, which makes it easier for crushing blockage to occur, and the blockage will not only affect the normal operation of the crusher, but also cause equipment damage; finally, too much stone entering the crushing chamber will increase the wear of the moving cone, the fixed cone and the liner, especially when the stone contains sharp or hard particles, the wear will be more serious, which will shorten the life of the equipment and increase the maintenance cost in the long run. At the same time, in order to process more stones, the transmission mechanism and the eccentric mechanism require greater driving force, resulting in increased energy consumption, which not only increases the operating cost, but also imposes a greater burden on the environment; 2. Compared with the prior art, when the cone crusher is working, the moving cone performs a pendulum motion under the action of the eccentric mechanism. This motion mode causes the material to be squeezed and collided multiple times between the moving cone and the static cone, but the direction and strength of the collision are not fixed, so that the material is irregularly flipped, and the particle size, shape and hardness of the material entering the crushing chamber are different. These differences in properties cause the reaction and movement state of the material to be different when it is squeezed and collided, further aggravating the irregular movement of the material. However, a large number of invalid collisions will occur in the process of irregular flipping of the material. These collisions do not effectively crush the material, but consume energy, resulting in reduced energy utilization. In addition, the irregular motion will also cause the distribution of energy in the material to become dispersed, and it cannot be concentrated on the crushing point of the material, which reduces the crushing efficiency and increases the energy consumption of the equipment. In view of this, the present invention proposes a cone crusher with a protective crushing chamber for construction waste to make up for and improve the shortcomings of the prior art.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This device introduces a moving cone liner with a guide spiral groove on the outer wall. According to the moving cone movement trajectory and the flow path of material crushing, the movement of materials in the crushing chamber is more directional. When the moving cone performs a rotary swing motion, the materials move in an orderly manner along the spiral groove, reducing irregular flipping. This orderly movement ensures that the materials receive the crushing force more effectively, avoiding energy dispersion caused by irregular movement of the materials. In addition, from the perspective of material flow, the spiral groove guides the materials to flow in a spiral shape from the entrance to the exit of the crushing chamber, making the distribution of materials in the crushing chamber more uniform. This not only improves the space utilization rate of the crushing chamber, but also improves the fluidity of the materials, which helps to achieve continuous and stable crushing operations, reduces equipment downtime caused by poor material flow, and improves the overall operation efficiency of the equipment; Compared with the traditional crushing chamber, this device guides the material so that the energy can be more concentrated on the material crushing process, thereby improving the energy transfer efficiency and helping to achieve better crushing effect under the same input energy; Secondly, this device introduces a new shape of fixed cone liner, so that a layered crushing area is formed between the fixed cone liner and the moving cone liner, and the crushing process is divided into two stages: primary crushing and fine crushing. In the primary crushing area at the top of the crushing chamber, the larger distance between the moving cone and the fixed cone is suitable for crushing large particles. At this time, small particles will continue to flow downward and be processed by the fine crushing area below, so that large particles can be effectively crushed into medium particles, achieving a larger crushing ratio. Subsequently, the processed medium particles enter the more compact fine crushing area at the bottom and are further crushed into smaller particles. This layered crushing structure helps to gradually improve the crushing ratio in the entire crushing process, so that the cone crusher can adapt to a wider range of feed particle sizes and produce products with more uniform particle sizes that meet the requirements. Compared with the existing technology, this device uses layered crushing processing to make the equipment more targeted during crushing, thereby avoiding the ineffective energy consumption of materials of different particle sizes in the same area, so that the energy can be accurately applied to the crushing process of materials of corresponding particle sizes, thereby ensuring that the equipment can adapt to a wider range of feed particle sizes and can produce products with more uniform particle sizes and better meet the requirements; Finally, this device introduces the design of an asymmetric fixed cone liner structure to divide the fixed cone into a main crushing area and a secondary auxiliary area. First, the main crushing area has a stronger crushing force application ability under the support of the side weight bin and the crushing rib group, and can crush the material more effectively when the movable cone performs a swinging motion. This design optimizes the distribution of the crushing force, so that in each swinging motion, more energy is used for material crushing instead of being wasted on irregular material flipping. The oppositely designed secondary auxiliary area can cooperate with the guide spiral groove on the outer wall of the movable cone liner, which helps to guide the material to be reasonably distributed in the crushing chamber, guide the material to a suitable position, avoid irregular flipping and accumulation of the material, thereby improving the uniformity of material distribution in the crushing chamber and helping to improve the stability and reliability of the entire crushing process. Compared with the traditional symmetrical moving cone structure, where materials are prone to local accumulation or uneven distribution, the main crushing area in the asymmetric fixed cone structure introduced by this device can achieve more effective crushing per unit time, thereby enhancing the crushing efficiency of the equipment. In addition, by guiding the materials in the secondary auxiliary area in the asymmetric fixed cone structure, local accumulation or uneven distribution of materials can be avoided. More importantly, in order to improve the crushing capacity of the main crushing area, the device introduces a side weight bin on its side wall, and the interior of the side weight bin is designed to be partially hollowed out, and the hollowed-out part is filled with water; From the perspective of mass and inertia, the mass of water will increase the overall mass of one side of the main crushing area, and water has a certain fluidity. During the movement of the dynamic cone, the shaking of water will increase the dynamic inertia of this side to a certain extent, thereby generating a stronger crushing force when it comes into contact with the material; From the perspective of energy transfer, due to the increase in mass of the main crushing area, it has more kinetic energy during the swing motion. When this side collides with the material, it can transfer more energy to the material. In addition, water can also be used as a medium for energy transfer. When the fixed cone is impacted, water can disperse the energy more evenly in the internal structure of the thickened side, reducing local stress concentration. At the same time, it can also transfer more energy to the surface in contact with the material, thereby enhancing the crushing effect. From the perspective of heat transfer, water as a heat transfer medium can effectively absorb the heat generated by the fixed cone during the crushing process. Water has a high specific heat capacity, which means that it can absorb a large amount of heat while its own temperature rise is relatively small. During the crushing process, the heat generated by the fixed cone is transferred to the water inside. The water absorbs and transfers part of the heat, thereby achieving a cooling effect on the fixed cone, reducing the temperature of the fixed cone and helping to extend the service life of the fixed cone. From the perspective of structural stability, the device evenly installs limit plates inside the side weight bin to limit the direction of water flow inside the side weight bin, preventing water from leaking and the internal structure from being damaged by the shaking of water during the violent swinging of the moving cone. This structure can stably achieve stronger crushing, and correspondingly, a counterweight is installed below the secondary auxiliary area to adjust the weight balance at both ends of the fixed cone and reduce the weight difference between different areas at both ends, so that the moving cone can maintain balance and reduce vibration during overall operation, ensuring that the moving cone can swing smoothly, thereby improving the stability and reliability of the cone crusher operation. (2) The device drives the adjustment plate through the transmission shaft to continuously spray and inhale the lubricating oil in the oil storage tank, thereby forming a stable oil film layer on the outer wall of the bevel gear transmission part. In this way, more comprehensive and uniform lubrication can be achieved, so that the oil film can effectively fill the tiny unevenness on the surface of the bevel gear transmission part, reduce the direct contact between the tooth surfaces, and thus make the gear meshing smoother, reduce the friction coefficient between the tooth surfaces, thereby improving the lubrication efficiency, helping to reduce gear wear and extend the service life of the bevel gear transmission part; Compared with the existing technology, this oil film formation is a dynamic change, which can continuously provide lubricating oil to the transmission parts. During the long-term operation of the cone crusher, stable lubrication helps to maintain the mechanical properties of the bevel gear transmission parts, thereby ensuring that the bevel gear transmission parts can maintain a good working condition under various working conditions, and improving the reliability of the entire drive module; Moreover, the oil film cooling mechanism can also realize the recycling of lubricating oil, make full use of the performance of lubricating oil, so that each sprayed and sucked lubricating oil can be reused, reducing the consumption of lubricating oil, so that in the long-term production process, it is not necessary to frequently replace and replenish a large amount of lubricating oil, thereby improving the use efficiency of lubricating oil and helping to reduce the operating cost of equipment. At the same time, by recycling lubricating oil, the replenishment frequency and total amount of lubricating oil are also reduced, thereby reducing the possibility of harm to the environment due to improper handling of lubricating oil, and helping the equipment to achieve higher standards in environmental protection; It is particularly important that in order to prevent the oil film from being excessively thrown out due to the centrifugal force when the transmission shaft rotates at high speed, the device generates an upward wind flow by introducing a fan ring to rotate synchronously with the transmission shaft, and the air flow is converted into a spiral flow by the turbine group to flow around the transmission shaft. The spiral air flow exerts an inward pressure on the oil film, which helps to resist the centrifugal force, thereby improving the oil film's ability to retain the outer wall of the transmission shaft and the bevel gear transmission part, so that the oil film can be more stably attached to the surface of the transmission part, ensuring that the bevel gear transmission part is always in a good lubrication state, and helping to reduce the probability of tooth surface wear, bonding and other faults caused by lack or uneven oil film; Moreover, when the spiral airflow flows around the transmission shaft, it will have a combing and guiding effect on the oil film, thereby making the oil film more evenly distributed on the surface of the transmission shaft and the bevel gear transmission parts, avoiding the accumulation of oil film in some areas and loss in other areas; At the same time, when the spiral airflow flows around the oil film, it can effectively take away the heat of the oil film. As a good heat transfer medium, the flow of air can accelerate the heat exchange between the oil film and the surrounding environment. Compared with natural heat dissipation, this forced convection heat dissipation method greatly improves the heat dissipation efficiency of the oil film. By lowering the temperature of the oil film, the viscosity of the oil film can be kept within an appropriate range to ensure its good lubrication performance. For example, in a high temperature environment or when the equipment is running at high load, this heat dissipation method helps prevent the oil film from becoming thinner due to excessive temperature, thereby losing effective protection for the transmission parts, and improving the stability of the oil film under harsh working conditions.

[0019] 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; It should be noted that the structures and working principles of the above-mentioned supporting frame 1, driving module 11, crushing module 12, oil delivery module 13 and other components belong to the prior art and will not be described in detail here.

[0020] Example 1: Please refer to Figure 1 and Figure 2 As shown, a cone crusher with a protective crushing chamber for construction waste includes a support frame 1, a crushing module 12 is installed above the support frame 1, and an energy optimization mechanism 2 is arranged inside the crushing module 12. The energy optimization mechanism 2 is used to improve the crushing efficiency and energy utilization rate of the equipment; It should be noted that the threaded sleeve 33 and the blade ring 35 are fixedly connected to the outer wall of the transmission shaft in the drive module 11, the turbine group 36 is rotatably connected to the outer wall of the transmission shaft in the drive module 11, and a ball screw structure is formed between the adjustment plate group 32 and the threaded sleeve 33. An oil delivery module 13 is installed below the support frame 1, and the oil delivery module 13 includes an oil pump and an oil delivery pipe. The interior of the oil storage tank 31 is connected to the oil delivery pipe in the oil delivery module 13.

[0021] Please refer to Figures 2 to 8 As shown, the energy optimization mechanism 2 includes a fixed cone liner 21 installed inside the crushing module 12, a moving cone liner 22 is installed inside the fixed cone liner 21, a crushing rib group 23 is installed on the inner side wall of the fixed cone liner 21, a side weight bin 24 is installed on the outer side wall of the fixed cone liner 21, a limit plate 25 is evenly fixedly connected to the inner side wall of the side weight bin 24, and a counterweight block 26 is installed on the lower surface of the fixed cone liner 21; It should be noted that the outer wall of the moving cone liner 22 is fixedly connected with a guide spiral groove, the fixed cone liner 21 and the moving cone liner 22 are located at the same axial point, the outer wall of the side weight bin 24 is made of aluminum alloy, and the outer wall of the side weight bin 24 is connected with a connecting pipe, the fixed cone liner 21 as a whole is composed of a main crushing area and a secondary auxiliary area, the crushing rib group 23 is composed of a combination of no less than ten ribs, the ribs are convex in an arc shape, and the crushing rib group 23 as a whole is located in the main crushing area of ​​the fixed cone liner 21. The side weight bin 24 is located on the outer wall of the main crushing area in the fixed cone liner 21, and the counterweight block 26 is located on the lower surface of the secondary auxiliary area in the fixed cone liner 21. Water is stored in the side weight bin 24. The water in the side weight bin 24 is evenly distributed through the limiting plate 25, and the two sides of the limiting plate 25 are fixedly connected with guide columns. The distance between the fixed cone liner 21 and the movable cone liner 22 gradually decreases from top to bottom, and the middle position of the fixed cone liner 21 is an inwardly concave arc shape.

[0022] Specifically, the side wall of the side weight bin 24 is made of aluminum alloy. In actual operation, the good thermal conductivity of aluminum alloy can gradually absorb the heat of the moisture inside the side weight bin 24. Since the side weight bin 24 is located in the non-working area inside the equipment, its heat dissipation is relatively fast, and the moving cone liner 22 will not contact it during operation. In addition, Figure 2 He Ru Figure 3 As shown, a connecting pipe is added to the outside of the side weight bin 24, so that when the equipment works intermittently, that is, when the equipment stops running, the staff can replace the moisture inside the side weight bin 24 through the connecting pipe. The side weight bin 24 is installed as a whole on the outer wall of the fixed cone liner 21. In actual use, the fixed cone liner 21 remains stationary. Based on this, adding a connecting pipe to the outer wall of the side weight bin 24 will not affect the normal movement principle of the equipment. Since the moving cone in the crushing module 12 has a specific trajectory for the swinging motion, and the guiding spiral groove on the outer wall of the moving cone liner 22 is designed according to the moving cone motion trajectory, when the moving cone swings, the space between the moving cone and the fixed cone will continue to change. Since the shape and position of the spiral groove match the moving cone motion trajectory, the material will be guided by the spiral groove in this dynamically changing space. For example, the moving cone will squeeze the material in the process of approaching the fixed cone, and the existence of the spiral groove makes the material only squeezed and moved along the direction of the groove, instead of randomly spreading in all directions, thereby realizing the directionality of material movement; According to the shape characteristics of the fixed cone liner 21, when the input material is in the preliminary crushing area, due to the large spacing between the moving cone and the fixed cone, the small particle material will not be over-crushed in this area, and the small particle material can continue to flow downward under the action of gravity and directly enter the subsequent fine crushing area. This feature enables the device to adapt to the situation where large particles and small particles exist in the feed at the same time. Regardless of the distribution of the feed particle size, the large particles can be processed through the preliminary crushing area, while the small particles can pass quickly, so that the cone crusher can process feeds of various different particle sizes, expanding the feed particle size range of the equipment. At the same time, the medium-sized particle material after the preliminary crushing enters the more compact fine crushing area at the bottom. In the fine crushing area, due to the reduction in the spacing, the moving cone and the fixed cone have a stronger squeezing and grinding effect on the particles, which can further crush these medium particles into smaller particles. Then, this layered structure enables the equipment to carry out targeted crushing according to materials of different particle sizes, thereby adapting to a wider range of feed particle sizes. In addition, the device divides the fixed cone liner 21 into a main crushing area and a secondary auxiliary area. Under the support of the side weight bin 24 and the counterweight block 26, the main crushing area of ​​the fixed cone liner 21 has a larger mass. According to the principle of inertia, the larger the mass of an object, the more difficult it is to change its state of motion. When the moving cone performs a pendulum motion, the main crushing area increases in inertia due to the increase in mass. During the movement of the moving cone, the side with large inertia can exert a greater impact force when contacting the material. In addition, the device designs the side weight bin 24 to be hollow, and fills the hollow position inside with water. The mass of the water will also increase the overall mass of this side. Moreover, the water has a certain fluidity. During the movement of the moving cone, the shaking of the water will increase this side to a certain extent. The dynamic inertia on one side generates a stronger crushing force when it comes into contact with the material. In addition, when the hollow interior is filled with water, the water can be used as a medium for energy transfer. When the moving cone is impacted, the water can disperse the energy more evenly in the internal structure of the main crushing area, reducing local stress concentration. At the same time, it can also transfer more energy to the surface in contact with the material, thereby enhancing the crushing effect. At the same time, in the continuous crushing process, the moving cone will generate a lot of heat due to continuous friction with the material and application of crushing force, and the water flow inside the side weight bin 24 can absorb the heat in time to prevent the moving cone from deformation due to overheating. Especially when processing high-hardness and large-capacity materials, the cooling structure can ensure the normal operation of the moving cone.

[0023] Example 2: Based on Example 1, please refer to Figures 9 to 12As shown, a driving module 11 is installed above the support frame 1, and an oil film cooling mechanism 3 is arranged inside the driving module 11. The oil film cooling mechanism 3 is used to evenly spray the lubricating oil and cool the lubricating oil. The oil film cooling mechanism 3 includes an oil storage bin 31 installed inside the driving module 11, and an adjusting plate group 32 is slidably connected inside the oil storage bin 31, and a threaded sleeve 33 is installed inside the adjusting plate group 32. A nozzle bin 34 is connected above the oil storage bin 31, and a fan blade ring 35 is installed inside the nozzle bin 34. A turbine group 36 is installed above the fan blade ring 35. It should be noted that lubricating oil is stored in the oil storage tank 31, the outer wall of the adjustment plate group 32 is evenly fixedly connected with an inclined plate, and the nozzle tank 34 is in the form of a cone that is narrow at the top and wide at the bottom. The turbine group 36 is composed of a plurality of inclined fan-shaped plates. The fan ring 35 and the turbine group 36 are located on the same vertical plane. The crushing module 12 includes a moving cone and a fixed cone. The fixed cone liner 21 and the moving cone liner 22 are respectively installed on the outside of the fixed cone and the moving cone. The driving module 11 includes a driving motor, a bevel gear transmission, a transmission shaft and an eccentric sleeve. The driving motor drives the transmission shaft to rotate, and the transmission shaft transmits power to the eccentric sleeve, and the eccentric sleeve drives the moving cone to perform a rotational pendulum motion.

[0024] Specifically, since the structure between the adjusting plate group 32 and the threaded shaft sleeve 33 is similar to that of a ball screw, and the pitch of the threaded shaft sleeve 33 is equal to the inner diameter of the adjusting plate group 32, and the angle between the tangent of the thread and the cylinder and the horizontal plane is greater than 45 degrees, when the threaded shaft sleeve 33 keeps rotating, the rotational force can be smoothly transmitted to the adjusting plate group 32. Since the threads on the outer wall of the threaded shaft sleeve 33 are in a bidirectional cross form, after the adjusting plate group 32 moves to the top of the threaded shaft sleeve 33, it can continue to move downward along the bidirectional cross threads on the outer wall, thereby realizing reciprocating linear movement. The rotation of the moving shaft has a stable speed and torque. Therefore, when the transmission shaft drives the adjusting plate group 32 to move, this stable power transmission provides a regular power source for the ejection and suction of the lubricating oil. Driven by this stable power, the motion trajectory of the adjusting plate group 32 is relatively fixed, so that its movement in the oil storage tank 31 can accurately control the flow direction and flow rate of the lubricating oil. Since the movement of the adjusting plate group 32 is predictable and stable, the speed, pressure and direction of the lubricating oil when it is ejected from the oil storage tank 31 are also relatively stable, which helps to form a uniform oil film on the outer wall of the bevel gear transmission member. like Fig.11As shown, the nozzle bin 34 is composed of a circular ring and a cone at the bottom. Specifically, when the adjusting plate group 32 moves upward, the lubricating oil in the oil storage bin 31 can be squeezed upward, so that the lubricating oil is sprayed out from the conical part of the nozzle bin 34. Since the conical part of the nozzle bin 34 is narrower at the top and fits the outer wall of the transmission shaft, the lubricating oil is easy to control when spraying, and can act on the outer wall of the transmission shaft. Because the adjusting plate group 32 will perform a downward reset movement, when the adjusting plate group 32 moves downward, a suction force will be generated at the position of the nozzle bin 34, thereby sucking back the lubricating oil acting on the outer wall of the transmission shaft, and then through the reciprocating movement of the adjusting plate group 32, the spraying and suction recycling of the lubricating oil can be realized; like Fig.11 As shown, the turbine group 36 is located above the fan ring 35. When the fan ring 35 rotates, it pushes the air to form an airflow, generating a wind force with a certain direction and speed. When this wind force encounters the turbine group 36, since the turbine group 36 is composed of a plurality of inclined fan-shaped plates, according to the principle of fluid mechanics, the fluid will change the flow direction when encountering an obstacle. Each inclined fan-shaped plate will guide the passing gas. When the airflow hits the fan-shaped plate, the inclined surface of the fan-shaped plate will make the airflow flow along its surface direction, thereby changing the original direction of the airflow. Multiple fan-shaped plates are combined together, and the airflow passes through different When the fan-shaped plates are used, each change of direction is superimposed on the previous one, and the flow direction of the airflow is constantly changed. The cumulative effect of multiple fan-shaped plates on the direction of the airflow eventually makes the gas no longer flow in a straight line, but gradually forms a spiral flow trajectory. The formation of this trajectory is similar to the effect of the turbine on the airflow in a turbocharger. Finally, as the gas continues to flow, its flow direction is constantly changed, thus forming a spiral flow trajectory, which surrounds the outer wall of the drive shaft upward, and only performs a concentrated surrounding effect on the outer wall of the drive shaft, thereby effectively taking away the heat of the oil film and accelerating the heat exchange between the oil film and the surrounding environment.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
