Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt production, and in particular relates to an asphalt gravel overflow dust-proof recovery mechanism. Background Art

[0002] In traditional asphalt production sites, a large amount of overflow often occurs in asphalt mixing equipment, which causes a significant change in the gradation of the mixture, thus affecting the quality of the finished product. The reason for the overflow is that the hot material in the hot material bin is added too quickly. In order to meet the gradation of the mixture, part of the hot material that is overfilled in the hot material bin must be discharged. This is the "overflow phenomenon". The overflow phenomenon often occurs, so a collection device for collecting overflow is set outside the hot material bin. The asphalt gravel overflow collected in the collection device is recycled and reused through the recovery equipment.

[0003] Existing recycling equipment is generally a conveyor belt equipment. During the process of conveying asphalt gravel overflow by the conveyor belt equipment, the asphalt gravel overflow is exposed to the outside. The dust attached to the asphalt gravel will be separated from the asphalt gravel due to the flow of external air and the vibration of the conveyor belt and diffused into the surrounding environment, causing pollution to the surrounding environment and posing a certain threat to the health of the workers.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0017] 1. In the present application, the upper notch of the trough-shaped feeding mechanism is sealed by a dust-proof plate to prevent dust from being discharged from the upper notch of the trough-shaped feeding mechanism during the transportation of asphalt gravel, thereby polluting the environment. In addition, during the transportation of asphalt gravel, the dust attached to its surface will scatter and diffuse into the transmission channel surrounded by the dust-proof plate and the trough-shaped feeding mechanism, thereby separating the asphalt gravel from the dust. When the asphalt gravel is transported from the feeding channel to the vicinity of the discharge assembly, the dust in the transmission channel surrounded by the dust-proof plate and the trough-shaped feeding mechanism is extracted through the suction port with an external negative pressure fan, thereby cleaning the dust mixed in the asphalt gravel. In the process of recycling asphalt gravel overflow, this recycling mechanism will not allow dust to diffuse into the external environment, thereby reducing the pollution of the environment by dust during the recycling process and reducing the harm to the health of the staff.

[0018] 2. As a preferred embodiment of the present invention, the dust shielding plate of the feed channel is located at one end away from the discharge assembly.

[0019] This structural design can ensure that the asphalt gravel transfer journey is long enough, so that the dust and the asphalt gravel are separated more fully, and the dust cleaning effect on the surface of the asphalt gravel is effectively increased.

[0020] 3. As a preferred embodiment of the utility model, the U-shaped plate is installed by fastening the U-shaped plate to the upper notch of the trough-shaped feeding mechanism and then fixing the U-shaped plate to the interface of the trough-shaped feeding mechanism by fixing bolts, thereby achieving a dust-proof effect in the asphalt gravel overflow recovery process. The setting of the handle makes it easy for workers to move and carry the dust-shielding plate.

[0021] The suction port is externally connected to a negative pressure dust suction fan, and a filter is provided inside the suction port. The negative pressure dust suction fan is provided to facilitate extraction of dust from the dust removal cover and the trough-shaped feeding mechanism, and a collection container for collecting dust is provided at the end of the exhaust pipe of the negative pressure dust suction fan. When the negative pressure dust suction fan is working, the filter is provided to facilitate isolation of asphalt gravels with larger particle size, thereby preventing larger asphalt particles from causing damage to the negative pressure dust suction fan.

[0022] 4. As a preferred embodiment of the present invention, a feed trough is used to provide a guide track for the transportation of asphalt gravel, and the setting of a transmission component facilitates driving the asphalt gravel in the feed trough to move from the feed channel to the discharge component.

The conveyor belt is supported by a U-shaped support structure consisting of two sets of side rollers and a set of middle rollers. When asphalt stones are piled on the conveyor belt, the asphalt stones press down on the conveyor belt, causing the middle part of the conveyor belt to sink downward to form a groove, thereby increasing the stability of the asphalt stones during transportation.

[0024] The asphalt gravel on the side of the conveyor belt is enclosed by the setting of the pressure plate to prevent the asphalt gravel from falling from the side of the conveyor belt.

[0025] 5.

[0038] Reference Figure 1-Figure 3 A dust-proof recovery mechanism for asphalt gravel overflow includes a trough-shaped feeding mechanism, a discharging assembly is provided at either end of the trough-shaped feeding mechanism, a dust collecting cover 6 is provided on the discharging assembly, and a suction port 601 is provided on the dust collecting cover 6. A plurality of groups of dust shielding plates 2 are detachably connected to the notch at the upper end of the trough-shaped feeding mechanism, and a feeding channel 201 is provided on one group of the dust shielding plates 2.

[0039] Those skilled in the art will understand that when asphalt gravel overflows during the processing, the overflowed asphalt gravel will be collected in a collecting container arranged under the processing equipment. When a certain amount of asphalt gravel is collected in the collecting container, the discharge end of the collecting container is connected to the feed channel 201 of the collecting mechanism, and the discharge end of the collecting container is opened to guide the collected asphalt gravel along the feed channel 201 into the trough-shaped feeding mechanism, and the trough-shaped feeding mechanism transports the asphalt gravel to the recycling equipment for storage or reprocessing. When the recycling mechanism recovers the overflowed asphalt gravel, the upper end notch of the trough-shaped feeding mechanism is closed by the dust isolation plate 2 to prevent dust from being discharged from the upper end notch of the trough-shaped feeding mechanism during the transportation of the asphalt gravel, thereby polluting the environment. In addition, during the transportation of asphalt gravel, the dust attached to its surface will scatter and spread into the transmission channel surrounded by the dust-proof plate 2 and the trough-shaped feeding mechanism, so as to separate the asphalt gravel from the dust. When the asphalt gravel is transported from the feeding channel 201 to the vicinity of the discharge assembly, the dust in the transmission channel surrounded by the dust-proof plate 2 and the trough-shaped feeding mechanism is extracted through the suction port 601 by an external negative pressure fan, so as to clean the dust mixed in the asphalt gravel. In the process of recycling the overflow of asphalt gravel, the recycling mechanism will not spread dust to the external environment, which reduces the pollution of the environment caused by dust during the recycling process and reduces the harm to the health of the workers.

[0040] As a preferred example of the above embodiment, refer to Figure 1 and Figure 2 The dust shielding plate 2 of the feed channel 201 is located at one end away from the discharge assembly.

[0041] This structural design can ensure that the asphalt gravel transfer journey is long enough, so that the dust and the asphalt gravel are separated more fully, and the dust cleaning effect on the surface of the asphalt gravel is effectively increased.

After the U-shaped plate is buckled with the upper notch of the trough-shaped feeding mechanism, the U-shaped plate is fixed to the interface of the trough-shaped feeding mechanism by fixing bolts to complete the installation of the U-shaped plate, thereby achieving a dust-proof effect in the asphalt gravel overflow recovery process. The setting of the handle 202 facilitates the staff to move and carry the dust-shielding plate 2.

[0047] The active roller 301 is externally connected to a servo motor, which drives the active roller 301 to rotate so that the conveyor belt 304 moves in a circular motion to transport the asphalt stones. The conveyor belt 304 is supported by a U-shaped support structure composed of two sets of side rollers 302 and a set of middle rollers 303. When the asphalt stones are piled on the conveyor belt 304, the asphalt stones press down on the conveyor belt 304 so that the middle part of the conveyor belt 304 is sunken downward to form a groove, thereby increasing the stability of the asphalt stones during transportation.
