Description

Technical Field

[0001] The utility model relates to the technical field of asphalt recovery, in particular to an asphalt recovery device. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. It is a waterproof, moisture-proof and anti-corrosion organic gelling material, mainly used in coatings, plastics, rubber and other industries, as well as road paving.

[0003] Asphalt materials and asphalt composites are often used in the construction of some large buildings such as roads, bridges, roads, houses, etc. As the usage market continues to increase, asphalt mixtures will be damaged and need to be repaired. If the damaged or repaired asphalt mixtures are directly discarded, it will cause pollution to the environment. Therefore, asphalt recovery devices are often used to treat the asphalt mixtures. However, existing recovery devices will generate a large amount of dust when recycling the asphalt mixtures, which will then cause pollution to the environment. At the same time, since the crushed asphalt mixture is mixed with powder, it affects the reuse of the asphalt mixture. Utility Model Content

[0004] In order to reduce pollution to the environment, the present application provides an asphalt recovery device.

[0005] This application provides an asphalt recovery device, which adopts the following technical solution:

[0006] An asphalt recovery device includes a crushing box, a wastewater tank located at the bottom of the crushing box, and a guide plate located between the wastewater tank and the crushing box, the wastewater tank having a wastewater chamber located at the bottom of the crushing box and a cleaning chamber located at the side of the crushing box, the guide plate being located above the wastewater chamber, a water spray pipe being provided on the top of the crushing box for spraying liquid on the asphalt mixture entering the crushing box, a water permeable structure being provided on the guide plate for allowing liquid to enter the wastewater chamber via the water permeable structure, and the guide plate being arranged at an angle so that the crushed asphalt mixture enters the cleaning chamber along the guide plate.

[0007] By adopting the above technical solution, when recycling the asphalt mixture, the asphalt mixture is first poured into the crushing box, and then the crushing box crushes the asphalt mixture. The crushed asphalt mixture falls on the guide plate and slides along the guide plate into the cleaning chamber, and then the crushed asphalt mixture is cleaned in the cleaning chamber to increase the cleanliness of the asphalt mixture and facilitate the reuse of the recycled asphalt mixture.

[0008] Because the top of the crushing box has a water spray pipe, after the asphalt mixture is poured into the crushing box, the water spray pipe can spray liquid into the asphalt mixture, preventing dust from being raised during the crushing process, thereby reducing environmental pollution during the recycling of the asphalt mixture. The liquid sprayed onto the dust will fall onto the guide plate and enter the wastewater chamber through the permeable structure on the guide plate for collection, thus preventing dust from being mixed with the asphalt mixture and affecting the cleaning efficiency of the asphalt mixture.

[0009] Optionally, the material guide plate is provided with a plurality of water retaining ribs at intervals along its own inclination direction, and the water permeable structure is a groove-shaped structure provided at the connection between the water retaining rib and the material guide plate.

[0010] By adopting the above technical solution, since a plurality of water retaining ribs are arranged at intervals along the inclined direction of the guide plate, the water retaining ribs can block the liquid for cleaning dust, so as to prevent the liquid from falling into the cleaning cavity along the inclined direction of the guide plate, so as to ensure the cleanliness of the cleaning cavity as much as possible and improve the cleaning efficiency of the asphalt mixture; and since the permeable structure is a groove-shaped structure provided at the connection between the water retaining rib and the guide plate, the area of ​​the permeable structure for liquid to pass through is increased to a certain extent, so as to prevent the permeable structure from being easily blocked, thereby ensuring the permeability of the guide plate.

[0011] Optionally, a conveyor belt is further included, which has a conveying starting end and a conveying end opposite to the conveying starting end, and the conveyor belt is arranged to be inclined upward from the conveying starting end to the conveying end, and the conveying starting end is located in the cleaning chamber and below the material guide plate.

[0012] By adopting the above-mentioned technical solution, the asphalt mixture falling on the guide plate slides along the inclined direction of the guide plate, and then the asphalt mixture falls into the cleaning chamber and falls to the conveying starting end of the conveyor belt. The liquid in the cleaning chamber cleans the asphalt mixture, and then the conveyor belt conveys the asphalt mixture, and finally the cleaned asphalt mixture falls through the conveying end of the conveyor belt. During this process, no manual intervention is required, so as to achieve the effect of facilitating the cleaning of the asphalt mixture.

[0013] Optionally, a guide hopper is provided between the conveying starting end and the guide plate, so that the asphalt mixture falling through the guide plate falls onto the conveyor belt through the guide hopper.

[0014] By adopting the above technical solution, since a guide hopper is provided between the conveying starting end and the guide plate, the guide hopper guides the asphalt mixture falling through the guide plate so that the asphalt mixture falls onto the conveyor belt, thereby avoiding the situation where part of the asphalt mixture cannot fall onto the conveyor belt and is wasted or increases the workload of the staff.

[0015] Optionally, the conveyor belt has a belt body, and a plurality of material blocking ribs are provided on the belt body, and the plurality of material blocking ribs are arranged at intervals along the circumference of the belt body.

[0016] By adopting the above technical solution, since a plurality of blocking ribs are provided on the belt body, the blocking ribs can block the asphalt mixture falling onto the belt body to prevent the asphalt mixture from sliding along the inclined direction of the belt body, thereby increasing the transmission efficiency of the asphalt mixture.

[0017] Optionally, a material blocking plate is hingedly connected to a side of the material guide hopper away from the conveying end, and the material blocking plate can swing under the action of the material blocking rib to avoid the material blocking rib.

[0018] By adopting the above technical solution, since there is a distance between two adjacent material-blocking ribs, the asphalt mixture may slide along the belt body into the cleaning chamber when falling through the guide hopper. By setting the material-blocking plate, the material-blocking plate can block the asphalt mixture to avoid the asphalt mixture sliding along the inclined direction of the belt body, thereby ensuring the transmission efficiency of the asphalt mixture. On the other hand, when the material-blocking rib moves to the position of the material-blocking plate, the material-blocking plate can rotate under the action of the material-blocking rib, so that the material-blocking plate and the material-blocking rib form a avoidance, thereby ensuring the normal rotation of the belt body.

[0019] Optionally, a spray pipe is provided at the bottom of the guide hopper to clean the asphalt mixture falling through the guide hopper.

[0020] By adopting the above technical solution, since a spray pipe is provided at the bottom of the guide hopper, when the asphalt mixture falls through the guide hopper, the spray pipe can spray cleaning water on the asphalt mixture to further clean the asphalt mixture, thereby greatly improving the cleaning effect of the asphalt mixture.

[0021] Optionally, the spray pipe sprays the liquid at an angle from bottom to top.

[0022] By adopting the above technical solution, since the injection pipe sprays liquid from bottom to top at an angle, the liquid sprayed through the injection pipe acts on the bottom of the asphalt mixture to exert an upward force on the asphalt mixture, thereby slowing down the falling speed of the asphalt mixture and improving the cleaning effect of the asphalt mixture.

[0023] Optionally, a protective plate is provided in the guide hopper and is located above the injection pipe, and the vertical projection of the protective plate covers the injection pipe.

[0024] By adopting the above technical solution, since the projection of the protective plate in the vertical direction covers the injection pipe, the protective plate can protect the injection pipe to avoid the asphalt mixture from causing damage to the injection pipe, thereby extending the service life of the injection pipe and ensuring the cleaning effect of the asphalt mixture.

[0025] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0026] 1. The asphalt recovery device of the present application includes a crushing box, a wastewater tank located at the bottom of the crushing box, and a guide plate located between the wastewater tank and the crushing box. The wastewater tank has a wastewater chamber located at the bottom of the crushing box and a cleaning chamber located on the side of the crushing box. The guide plate is located above the wastewater chamber. A water spray pipe is provided at the top of the crushing box to spray liquid onto the asphalt mixture entering the crushing box. The guide plate has a permeable structure for liquid to enter the wastewater chamber through the permeable structure. The guide plate is tilted so that the crushed asphalt mixture flows along the guide plate into the cleaning chamber. Because the water spray pipe is provided at the top of the crushing box, the water spray pipe can spray liquid onto the asphalt mixture after it is poured into the crushing box, thereby preventing dust from being raised during the crushing of the asphalt mixture and reducing environmental pollution during the recovery of the asphalt mixture. The liquid sprayed onto the dust falls onto the guide plate and enters the wastewater chamber through the permeable structure on the guide plate for collection in the wastewater chamber, thereby preventing dust from being mixed with the asphalt mixture and affecting the efficiency of the asphalt mixture cleaning.

[0027] 2. The material guide plate in the present application is provided with a plurality of water retaining ribs at intervals along its own inclination direction, so that the water retaining ribs can block the liquid for cleaning dust, so as to prevent the liquid from falling into the cleaning cavity along the inclination direction of the material guide plate, so as to ensure the cleanliness of the cleaning cavity as much as possible and improve the cleaning efficiency of the asphalt mixture. The permeable structure is a groove-shaped structure provided at the connection between the water retaining rib and the material guide plate, which increases the area of ​​the permeable structure for liquid to pass through to a certain extent, so as to avoid the situation where the permeable structure is easily blocked, thereby ensuring the permeability of the material guide plate.

[0028] 3. The asphalt recovery device in the present application also includes a conveyor belt, which has a conveying start end and a conveying end opposite to the conveying start end. The conveyor belt is inclined upward in the direction from the conveying start end to the transmission end. The conveying start end is located in the cleaning chamber and below the guide plate. The asphalt mixture falling on the guide plate slides along the inclined direction of the guide plate, and then the asphalt mixture falls into the cleaning chamber and falls to the conveying start end of the conveyor belt. The liquid in the cleaning chamber cleans the asphalt mixture, and then the conveyor belt conveys the asphalt mixture, and finally the cleaned asphalt mixture falls through the conveying end of the conveyor belt. No manual intervention is required in this process, so as to achieve the effect of facilitating the cleaning of the asphalt mixture. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-2 This application is described in further detail.

[0033] The embodiment of the present application discloses an asphalt recovery device.

[0034] refer to Figure 1 An asphalt recovery device includes a crushing box 1, a wastewater tank 2 located at the bottom of the crushing box 1, and a guide plate 3 located between the wastewater tank 2 and the crushing box 1. The wastewater tank 2 has a wastewater chamber 21 located at the bottom of the crushing box 1 and a cleaning chamber 22 located on the side of the crushing box 1. The guide plate 3 is located above the wastewater chamber 21. A water spray pipe 11 is provided on the top of the crushing box 1 to spray liquid on the asphalt mixture entering the crushing box 1. The guide plate 3 has a permeable structure 311 for liquid to enter the wastewater chamber 21 through the permeable structure 311, and the guide plate 3 is arranged at an angle so that the crushed asphalt mixture enters the cleaning chamber 22 along the guide plate 3.

[0035] It will be appreciated that the water spray pipe 11 is provided with a plurality of water spray holes and is connected to an external water supply device, which delivers a liquid, such as water, into the water spray pipe 11. The external water supply device then delivers a liquid, such as water, into the crushing chamber 11 to suppress dust generated during the crushing of the asphalt mixture. The cleaning chamber 22 is filled with cleaning water so that the crushed asphalt mixture can be cleaned by the cleaning water after it falls into the cleaning chamber 22.

[0036] When recycling the asphalt mixture, the asphalt mixture is first poured into the crushing box 1, and then the crushing box 1 crushes the asphalt mixture. The crushed asphalt mixture falls on the guide plate 3 and slides along the guide plate into the cleaning chamber 22. The crushed asphalt mixture is then cleaned in the cleaning chamber 22 to increase the cleanliness of the asphalt mixture and facilitate the reuse of the recycled asphalt mixture.

[0037] Because the top of the crushing box 1 is provided with a water spray pipe 11, after the asphalt mixture is poured into the crushing box 1, the water spray pipe 11 can spray liquid onto the asphalt mixture, thereby preventing dust from being raised during the crushing of the asphalt mixture and reducing environmental pollution during the recycling of the asphalt mixture. The liquid sprayed onto the dust will fall onto the guide plate 3 and enter the wastewater chamber 21 through the permeable structure 311 on the guide plate 3, where it will be collected. This prevents dust from being mixed with the asphalt mixture and affecting the cleaning efficiency of the asphalt mixture.

[0038] The present application does not make any specific limitation on the structure of the crushing box 1. Preferably, refer to Figure 1 The crushing box 1 includes a box body and at least two crushing rollers arranged in the box body, the two crushing rollers are arranged relative to each other and rotate relative to each other to squeeze and crush the asphalt mixture. In other embodiments, the crushing box 1 can also be a jaw crusher.

[0039] The present application does not specifically limit the structure of the water permeable structure 311. Preferably, refer to Figure 1 and Figure 2 The guide plate 3 is provided with a plurality of water retaining ribs 31 at intervals along its own inclination direction, and the water-permeable structure 311 is a groove-shaped structure provided at the connection between the water retaining rib 31 and the guide plate 3.

[0040] Since a plurality of water retaining ribs 31 are arranged at intervals along the inclined direction of the guide plate 3, the water retaining ribs 31 can block the liquid for cleaning dust to prevent the liquid from falling into the cleaning chamber 22 along the inclined direction of the guide plate 3, thereby ensuring the cleanliness of the cleaning chamber 22 as much as possible and improving the cleaning efficiency of the asphalt mixture; and since the permeable structure 311 is a groove-shaped structure provided at the connection between the water retaining rib 31 and the guide plate 3, the area of ​​the permeable structure 311 for liquid to pass through is increased to a certain extent, thereby preventing the permeable structure 311 from being easily blocked, thereby ensuring the permeability of the guide plate 3.

[0041] In other embodiments, the water-permeable structure 311 may also be a hole structure provided on the material guide plate 3 .

[0042] In a preferred embodiment, referring to Figure 1 and Figure 2 The asphalt recovery device also includes a conveyor belt 4, which has a conveying starting end and a conveying end opposite to the conveying starting end. The conveyor belt 4 is arranged upwardly inclined from the conveying starting end to the conveying end. The conveying starting end is located in the cleaning chamber 22 and below the guide plate 3.

[0043] It can be understood that the transfer end is located outside the cleaning chamber 22 and its projection in the vertical direction is located outside the cleaning chamber 22 .

[0044] The asphalt mixture that falls on the guide plate 3 slides along the inclined direction of the guide plate 3, and then falls into the cleaning chamber 22 and falls to the conveying starting end of the conveyor belt 4. The liquid in the cleaning chamber 22 cleans the asphalt mixture, and then the conveyor belt 4 conveys the asphalt mixture, and finally the cleaned asphalt mixture falls through the conveying end of the conveyor belt 4. In this process, no manual intervention is required, so as to achieve the effect of facilitating the cleaning of the asphalt mixture.

[0045] Further, refer to Figure 1 and Figure 2 A guide hopper 41 is provided between the conveying starting end and the guide plate 3 so that the asphalt mixture falling through the guide plate 3 falls onto the conveyor belt 4 through the guide hopper 41 .

[0046] Since a guide hopper 41 is provided between the conveying start end and the guide plate 3, the guide hopper 41 guides the asphalt mixture falling through the guide plate 3 so that the asphalt mixture falls onto the conveyor belt 4, thereby avoiding the situation where part of the asphalt mixture cannot fall onto the conveyor belt 4 and is wasted or increases the workload of the staff.

[0047] Further, refer to Figure 1 and Figure 2The conveyor belt 4 has a belt body, on which a plurality of material-blocking ribs 42 are arranged. The plurality of material-blocking ribs 42 are arranged at intervals along the circumference of the belt body, so that the material-blocking ribs 42 can block the asphalt mixture falling onto the belt body to prevent the asphalt mixture from sliding along the inclined direction of the belt body, thereby increasing the transmission efficiency of the asphalt mixture.

[0048] Further, refer to Figure 1 and Figure 2 A material blocking plate 411 is hingedly connected to the side of the guide hopper 41 away from the conveying end. The material blocking plate 411 can swing under the action of the material blocking rib 42 to avoid the material blocking rib 42.

[0049] Due to the distance between two adjacent material-blocking ribs 42, the asphalt mixture may slide along the belt body into the cleaning chamber 22 when falling through the guide hopper 41. By providing the material-blocking plate 411, the material-blocking plate 411 can block the asphalt mixture to prevent the asphalt mixture from sliding along the inclined direction of the belt body, thereby ensuring the transmission efficiency of the asphalt mixture. On the other hand, when the material-blocking rib 42 moves to the position of the material-blocking plate 411, the material-blocking plate 411 can rotate under the action of the material-blocking rib 42, so that the material-blocking plate 411 and the material-blocking rib 42 form a avoidance, thereby ensuring the normal rotation of the belt body.

[0050] It is understandable that the length of the baffle plate 411 is greater than the distance between the guide hopper 41 and the belt body, so that the baffle plate 411 can maintain a state of blocking the asphalt mixture under the support of the belt body.

[0051] In a preferred embodiment, a spray pipe 412 is provided at the bottom of the guide hopper 41 to clean the asphalt mixture falling through the guide hopper 41 .

[0052] Since the bottom of the guide hopper 41 is provided with a spray pipe 412, when the asphalt mixture falls through the guide hopper 41, the spray pipe 412 can spray cleaning water on the asphalt mixture to further clean the asphalt mixture, thereby greatly improving the cleaning effect of the asphalt mixture.

[0053] It can be understood that the spray pipe 412 is connected to an external water supply device, so that the external water supply device delivers water to the spray pipe 412 and then sprays water through the spray pipe 412 .

[0054] Furthermore, the injection pipe 412 sprays liquid at an angle from bottom to top, that is, the injection port of the injection pipe 412 is set upward, so that the liquid sprayed through the injection pipe 412 acts on the bottom of the asphalt mixture to exert an upward force on the asphalt mixture, thereby slowing down the falling speed of the asphalt mixture to improve the cleaning effect of the asphalt mixture.

[0055] Further, refer to Figure 1 and Figure 2 A protective plate 413 is provided in the guide hopper 41 and is located above the injection pipe 412. The vertical projection of the protective plate 413 covers the injection pipe 412, so that the protective plate 413 can protect the injection pipe 412 to prevent the asphalt mixture from damaging the injection pipe 412, thereby extending the service life of the injection pipe 412 and ensuring the cleaning effect of the asphalt mixture.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
