Description

Technical Field

[0001] The invention relates to the technical field of asphalt particle screening, in particular to an asphalt particle screening device for road asphalt. Background Art

[0002] Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, some of which form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, rubber, and paving roads; asphalt screening is to determine the content of aggregates of different particle sizes (such as stone particles, sand, etc.) in asphalt mixtures and ensure that the mixture meets specific specifications and requirements. In the asphalt screening process, the commonly used equipment is a screening machine (also called a vibrating screen), which has multiple layers of screens and can grade aggregates according to different particle sizes. When the raw materials pass through the screening machine, smaller particles will pass through the screen, while larger particles will be blocked, thereby achieving the separation of aggregates. Through asphalt screening, the proportion of each particle gradation in the asphalt mixture can be obtained, which is very important for controlling the quality, stability and performance of the mixture.

[0012] Beneficial Effects Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The asphalt particle screening equipment for road asphalt, when in use, asphalt particles enter the filtering mechanism through the feed port, and the entering asphalt particles are gradually flattened under the stirring action of the stirring device, so as to avoid the accumulation of asphalt particles inside the filtering mechanism, thereby reducing the working efficiency. The asphalt particles will generate a large amount of dust under the vibration filtering action of the filtering mechanism, and the dust in the asphalt particles will be absorbed and collected under the dust suction action of the dust suction device, thereby reducing the wear of the dust on the motor and other mechanisms in the device. The cooling device is turned on while the equipment is working, and the air cooling action is applied to the asphalt particles in the screening by the principle of heat transfer, thereby cooling the asphalt particles in the screening, so as to avoid the asphalt particles from adhering to the inside of the equipment due to excessive temperature during the working process, thereby reducing the working efficiency. The larger asphalt particles are discharged from the equipment through the discharge port and recycled, and the smaller asphalt particles are screened to the collection mechanism for collection. The device improves the screening efficiency of asphalt particles, making the screening process more efficient, and at the same time solves the problem that the asphalt particles will soften and adhere to the equipment when the temperature is too high; 2. The asphalt particle screening equipment for road asphalt, when in use, since the asphalt particles entering the filtering mechanism are easy to accumulate inside the device, after the asphalt particles enter the filtering mechanism, the first motor output shaft drives the first rotating shaft to rotate, so that the first rotating shaft drives the first sleeve and the second sleeve to rotate, and the rotation of the second sleeve drives the rotation of the paving rod, and the rotation of the paving rod drives the rotation of the paving shovel. Under the stirring action of the paving rod and the paving shovel, the originally accumulated asphalt particles are gradually flattened, so that the asphalt particles completely cover the filter screen, so that the utilization efficiency of the filter screen is maximized, thereby achieving the purpose of paving the asphalt particles entering the filtering mechanism to prevent the accumulation of asphalt particles, thereby improving work efficiency.

[0013] In the asphalt particle screening equipment for road asphalt, since the paving rod is provided with slots, asphalt particles may be stuck in the slots of the paving rod during operation. Therefore, while the first rotating shaft drives the first sleeve and the second sleeve to rotate, the first sleeve and the second sleeve drive the screw transmission mechanism to rotate. With the action of the screw transmission mechanism, the second sleeve moves upward, and the upward movement of the second sleeve drives the paving rod upward, and the upward movement of the paving rod drives the paving shovel upward. After the paving rod moves upward, the particles originally stuck in the paving rod fall down through the rotation, which solves the problem of the stirring device being stuck due to particles during the stirring process, thereby achieving the purpose of preventing asphalt particles from being stuck in the slots of the paving rod.

[0014] The asphalt particle screening device for road asphalt needs to be cooled down during use because the asphalt particles will adhere to the device when reaching a certain temperature. The second motor is fixed to one side of the motor seat on one side of the collecting mechanism. The rotation of the second motor drives the gear transmission assembly to perform transmission. The transmission action of the gear transmission assembly simultaneously drives the first transmission rod and the third transmission rod to rotate. The rotation of the first transmission rod drives the belt transmission assembly and the paving assembly to rotate. The transmission action of the belt transmission assembly drives the second transmission rod to rotate. The rotation of the first transmission rod, the second transmission rod and the third transmission rod drives the evenly distributed fan blades to rotate. The rotating fan blades not only generate wind force, but also accelerate the flow of air inside the device. Through the principle of heat transfer, the wind force acts on the asphalt particles in the screening device, so that the temperature of the asphalt particles is reduced, thereby air-cooling the asphalt, thereby achieving the purpose of avoiding the asphalt particles from adhering to the device due to excessive temperature.

[0015] In the asphalt particle screening equipment for road asphalt, the rotation of the first transmission rod drives the paving component to rotate, which in turn drives the paving blades in the paving component to rotate, and the rotation of the paving blades drives the rotating shovel to rotate. Under the pushing action of the rotating shovel, the smaller asphalt particles accumulated in the collecting mechanism are flattened, avoiding the accumulation of asphalt particles, so that the space in the collecting mechanism can be fully utilized, extending the time for the collecting mechanism to collect a full load, extending the single working time of the screening device, and improving work efficiency.

[0016] When the asphalt particle screening equipment for road asphalt is used, since the asphalt particles contain a large amount of fine dust, the dust will enter the motor and other mechanisms of the equipment during the screening process, thereby causing wear to the equipment, reducing the working efficiency and service life of the equipment. Therefore, the dust needs to be collected, and the dust inside the filter mechanism is sucked into the dust suction pipe through the suction action of the vacuum pump fixed on the top of the pump bracket. The dust enters the filter through the dust suction pipe. Part of the dust entering the filter falls into the recovery box under the action of gravity, and part of the dust adheres to the outer wall of the air filter element under the filtering action of the air filter element, and the sucked air is discharged through the vacuum pump.

[0017] The asphalt particle screening equipment for road asphalt, when the screening work is completed, turns on the third motor fixed on one side of the fixed plate, and the rotation of the output shaft of the third motor drives the brush plate to rotate through the bracket, thereby causing the brush plate to generate friction with the outer wall of the air filter element. Through the friction, the dust attached to the outer wall of the air filter element falls into the recovery box, the recovery box is pulled out, and the collected dust is cleaned, thereby achieving the purpose of preventing the dust in the asphalt particles from causing wear to the equipment and reducing the service life and working efficiency of the equipment.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] Example: See also Figure 1-3 The present invention provides a technical solution to solve the problem of low working efficiency of the currently used asphalt particle screening equipment. An asphalt particle screening equipment for road asphalt includes a filtering mechanism 2 and a collecting mechanism 4. The top of the filtering mechanism 2 is connected to a feed port 1. A discharge port 6 is provided on one side of the filtering mechanism 2. The filtering mechanism 2 is used to screen and filter the asphalt particles. The bottom of the filtering mechanism 2 is fixedly connected to the collecting mechanism 4. The collecting mechanism 4 is used to recycle the screened smaller asphalt particles. The invention also includes: A stirring device 3, which is arranged at the center of the top of the filter mechanism 2 and is used to stir and flatten the asphalt to prevent asphalt accumulation. The stirring device 3 passes through the top of the filter mechanism 2 and is fixedly connected to the filter mechanism 2; A cooling device 5, which is arranged on one side outside the filter mechanism 2 and is used to cool the asphalt. The cooling device 5 passes through one side of the filter mechanism 2 and is fixedly connected to the filter mechanism 2; The dust suction device 7 is arranged on the top of the middle support plate of the filter mechanism 2 and is used to absorb dust in the asphalt particles. The dust suction device 7 is fixedly connected to the filter mechanism 2.

[0024] When in use, asphalt particles enter the filtering mechanism 2 through the feed port 1. The entering asphalt particles are gradually flattened under the stirring action of the stirring device 3 to avoid the accumulation of asphalt particles inside the filtering mechanism 2, which reduces the working efficiency. The asphalt particles will generate a large amount of dust under the vibration filtering action of the filtering mechanism 2. Under the dust suction action of the dust suction device 7, the dust is collected, thereby reducing the wear of the dust on the mechanism in the device. When the equipment is working, the cooling device 5 is turned on at the same time to use air cooling to cool the asphalt particles being screened, so as to avoid the asphalt particles from sticking to the inside of the equipment due to excessive temperature during the working process, which reduces the working efficiency. The larger asphalt particles are discharged from the equipment through the discharge port 6 and recycled, and the smaller asphalt particles are screened to the collecting mechanism 4 for collection and storage in the receiving box 41; See also Figure 1-5 The present invention provides a technical solution to solve the problem that asphalt is easily accumulated and the working efficiency is low in the currently used asphalt particle screening equipment. The filtering mechanism 2 includes a filtering barrel 21, a filter element 22 is fixedly connected inside the filtering barrel 21, and an electromagnetic vibrator 23 is fixedly connected to the bottom of the filter element 22 through a flange. The top of the filtering barrel 21 is connected to the feed port 1, and the bottom of the filtering barrel 21 is fixedly connected to the collecting mechanism 4. The stirring device 3 includes a first motor 31, and the output end of the first motor 31 is fixedly connected to a first rotating shaft 32. The first rotating shaft 32 The middle and bottom are respectively sleeved with a first sleeve 33 and a second sleeve 35, one side of the first sleeve 33 is fixedly connected to a screw transmission mechanism 34, one side of the screw transmission mechanism 34 is fixedly connected to a second sleeve 35, one side of the second sleeve 35 is fixedly connected to a paving rod 36, one end of the paving rod 36 away from the second sleeve 35 is rotatably connected to a paving shovel 37 through a rotating shaft, one side of the first sleeve 33 is fixedly connected to a movable slide rail 38, one side of the movable slide rail 38 is fixedly connected to the second sleeve 35, and the bottom of the first motor 31 is fixedly connected to the filter barrel 21.

[0025] During use, since the asphalt particles entering the filtering mechanism 2 are prone to accumulate inside the device, after the asphalt particles enter the filtering mechanism 2, the rotation of the output shaft of the first motor 31 drives the first rotating shaft 32 to rotate, so that the first rotating shaft 32 drives the first sleeve 33 and the second sleeve 35 to rotate as well, and the rotation of the second sleeve 35 drives the paving rod 36 to rotate, and then the rotation of the paving rod 36 drives the paving shovel 37 to rotate, and the rotation of the paving rod 36 drives the paving shovel 37 to rotate. Under the stirring action of the paving rod 36 and the paving shovel 37, the originally accumulated asphalt particles are gradually flattened, so that the asphalt particles completely cover the filter screen, thereby maximizing the utilization efficiency of the filter screen, thereby achieving the purpose of paving the asphalt particles entering the filtering mechanism 2 to prevent the accumulation of asphalt particles, thereby improving work efficiency.

[0026] Since the paving rod 36 is provided with a slot, asphalt particles may be stuck in the slot of the paving rod 36 during operation. Therefore, while the first rotating shaft 32 drives the first sleeve 33 and the second sleeve 35 to rotate, the first sleeve 33 and the second sleeve 35 drive the screw transmission mechanism 34 to rotate. With the action of the screw transmission mechanism, the second sleeve 35 moves upward, and the upward movement of the second sleeve 35 drives the paving rod 36 to move upward. The upward movement of the paving rod 36 drives the paving shovel 37 to move upward. After the paving rod 36 moves upward, the particles originally stuck in the paving rod 36 fall down through the rotation, which solves the problem of the stirring device being stuck due to particles during the stirring process, thereby achieving the purpose of preventing asphalt particles from being stuck in the slot of the paving rod 36.

[0027] See also Figure 1-7 The present invention provides a technical solution to solve the problem that the asphalt particle screening equipment currently used is too hot during operation, causing asphalt to stick to the equipment. The cooling device 5 includes a motor base 51, and a second motor 52 is fixedly connected to one side of the motor base 51. The second motor 52 is connected to a first transmission rod 54 and a third transmission rod 57 through a gear transmission assembly 53. The first transmission rod 54 is connected to a second transmission rod 55 through a belt transmission assembly 56. The ends of the first transmission rod 54, the second transmission rod 55 and the third transmission rod 57 are all fixedly connected to blades 59. The first transmission rod 54 passes through and is fixedly connected to a paving assembly 58. The motor base 51 is fixedly connected to one side of the collecting mechanism 4. The paving assembly 58 includes a paving blade 581. The paving blade 581 is rotatably connected to a rotating shovel 582 through a pin shaft. The center position of the paving blade 581 passes through and is fixedly connected to the first transmission rod 54.

[0028] During use, since the asphalt particles will adhere to the equipment when reaching a certain temperature, the asphalt particles need to be cooled. The second motor 52 is fixed to one side of the motor base 51 on one side of the collecting mechanism 4. The rotation of the second motor 52 drives the gear transmission assembly 53 to perform transmission. The transmission action of the gear transmission assembly 53 simultaneously drives the first transmission rod 54 and the third transmission rod 57 to rotate. The rotation of the first transmission rod 54 drives the belt transmission assembly 56 and the paving assembly 58 to rotate. The transmission action of the belt transmission assembly 56 drives the second transmission rod 55 to rotate. The rotation of the first transmission rod 54, the second transmission rod 55 and the third transmission rod 57 drives the evenly distributed fan blades 59 to rotate. The rotating fan blades 59 not only generate wind force, but also accelerate the flow of air inside the device. Through the principle of heat transfer, the wind force acts on the asphalt particles in the screening device, so that the temperature of the asphalt particles is reduced, thereby cooling the asphalt by air, thereby achieving the purpose of avoiding the asphalt from adhering to the equipment due to excessive temperature.

[0029] The rotation of the first transmission rod 54 drives the paving assembly 58 to rotate, and then drives the paving blades 581 in the paving assembly 58 to rotate. The rotation of the paving blades 581 drives the rotating shovel 582 to rotate. Under the pushing action of the rotating shovel 582, the smaller asphalt particles accumulated in the collecting mechanism 4 are flattened, avoiding the accumulation of asphalt particles, so that the space in the collecting mechanism can be fully utilized, thereby improving work efficiency.

[0030] See also Figure 1-9 The present invention provides a technical solution to solve the problem that the dust generated by the currently used asphalt particle screening equipment during operation causes wear on the equipment, resulting in a reduction in the service life and working efficiency of the equipment. The dust suction device 7 includes a pump bracket 71, and the top of the pump bracket 71 is fixedly connected to an air pump 72, and the working end of the air pump 72 is connected to a filter 73, and the side of the filter 73 away from the air pump 72 is connected to a dust suction pipe 75, the pump bracket 71 is fixedly connected to the top of the support plate in the middle of the filtering mechanism 2, and the bottom of the filter 73 is slidably connected to a recovery box 74, and the recovery box 74 is connected through The slide rail is slidably connected to the top of the support plate of the filter mechanism 2, and the dust suction pipe 75 penetrates the filter mechanism 2 at one end away from the filter 73 and is fixedly connected to the filter mechanism 2. The filter 73 includes an air filter element 731, and a fixing plate 732 is fixedly connected to the top of the air filter element 731. A third motor 733 is fixedly connected to the top of the fixing plate 732. The output shaft of the third motor 733 is fixedly connected to a brush plate 734 through a bracket. The air filter element 731 is connected to the air inlet of the air pump 72 near the side of the air pump 72, and the air inlet of the air pump 72 penetrates and is fixedly connected to a shell 735.

[0031] During use, since the asphalt particles contain a large amount of fine dust, the dust will enter the motor and other mechanisms of the equipment during the screening process, thereby causing wear on the equipment, reducing the working efficiency and service life of the equipment. Therefore, the dust needs to be collected. Through the suction action of the vacuum pump 72 fixed on the top of the pump bracket 71, the dust inside the filter mechanism 2 is sucked into the dust suction pipe 75, and the dust enters the filter 73 through the dust suction pipe 75. Part of the dust entering the filter 73 falls into the recovery box 74 under the action of gravity, and part of it adheres to the outer wall of the air filter element 731 under the filtering action of the air filter element 731, and the sucked air is discharged through the vacuum pump 72.

[0032] When the screening work is completed, the third motor 733 fixed on one side of the fixed plate 732 is turned on. The rotation of the output shaft of the third motor 733 drives the brush plate 734 to rotate through the bracket, so that the brush plate and the outer wall of the air filter element 731 generate friction. Through the friction, the dust attached to the outer wall of the air filter element 731 falls into the recovery box 74, and the recovery box 74 is pulled out to clean the collected dust, thereby achieving the purpose of avoiding the dust in the asphalt particles from causing wear to the equipment and reducing the service life and working efficiency of the equipment.

[0033] Working principle: When in use, the asphalt particles that need to be screened enter the filter mechanism 2 through the feed port 1, pass through the filter barrel 21 and fall on the filter element 22. Through the principle of vibration screening and filtering, under the action of the electromagnetic vibrator 23, the asphalt particles on the filter element 22 vibrate, and the entering asphalt particles are flattened under the stirring action of the stirring device 3. The originally accumulated asphalt particles are gradually flattened to avoid the accumulation of asphalt particles inside the filter mechanism 2, which reduces the work efficiency. During filtering, the asphalt particles will generate a lot of dust under the vibration filtering action of the filter mechanism 2. Turn on the dust collection device 7. During the screening process, the dust will enter the motor and other mechanisms of the equipment. The dust in the filter mechanism 2 is sucked into the dust suction pipe 75 through the suction effect of the vacuum pump 72 fixed on the top of the pump bracket 71, and the dust in the filter mechanism 2 enters the filter 73 through the vacuum pipe 75. The dust in the filter 73 falls into the recovery box 74 under the action of gravity, and part of the dust adheres to the outer wall of the air filter element 731 under the filtering effect of the air filter element 731. The sucked air is discharged through the vacuum pump 72. When the screening work is completed, the third motor 733 fixed on one side of the fixed plate 732 is turned on. The third motor 733 The rotation of the output shaft drives the brush plate 734 to rotate through the bracket, thereby causing the brush plate to rub against the outer wall of the air filter element 731. Through the friction, the dust attached to the outer wall of the air filter element 731 falls into the recovery box 74, and the recovery box 74 is pulled out to clean the collected dust, thereby achieving the purpose of preventing the dust in the asphalt particles from causing wear to the equipment and reducing the service life and working efficiency of the equipment; while the equipment is working, the cooling device 5 is turned on. Since the asphalt particles will adhere to the equipment when they reach a certain temperature, the asphalt particles need to be cooled. The second motor 52 is fixed to the motor seat 5 on one side of the collecting mechanism 4 1, the gear transmission assembly 53 is driven by the rotation of the second motor 52 to perform transmission, and the transmission of the gear transmission assembly 53 simultaneously drives the first transmission rod 54 and the third transmission rod 57 to rotate, the rotation of the first transmission rod 54 drives the belt transmission assembly 56 and the paving assembly 58 to rotate, the transmission of the belt transmission assembly 56 drives the second transmission rod 55 to rotate, the rotation of the first transmission rod 54, the second transmission rod 55 and the third transmission rod 57 drives the evenly distributed fan blades 59 to rotate, and the rotating fan blades 59 not only generate wind force, but also accelerate the flow of air inside the device, thereby completing the cooling of the asphalt particles;After screening, the smaller particles enter the collecting mechanism 4. At this time, the rotation of the first transmission rod 54 drives the paving assembly 58 to rotate, and then drives the paving blades 581 in the paving assembly 58 to rotate. The rotation of the paving blades 581 drives the rotating shovel 582 to rotate. Under the pushing action of the rotating shovel 582, the smaller asphalt particles accumulated in the collecting mechanism 4 are paved, avoiding the accumulation of asphalt particles. After the screening, cooling, dust collection, collection and other processes, the machine is turned off and the screening work is completed. ;
