Description

Technical Field

[0001] The utility model relates to the field of preparation of colored asphalt concrete. More specifically, the utility model relates to a device for adding color powder to colored asphalt concrete. Background Art

[0002] Colored asphalt concrete refers to asphalt mixtures of various colors formed by mixing decolorized asphalt with various colored stones, colorants, additives and other materials at a specific temperature. The colored asphalt concrete can form a colored asphalt concrete pavement with certain strength and road performance after paving and rolling.

[0003] During the production process of colored asphalt, color powder needs to be added for dyeing. In the existing device for adding color powder to colored asphalt concrete, such as a device for adding color powder to colored asphalt concrete disclosed in the patent with the authorization announcement number CN 220990668 U, a discharge port is arranged at the bottom surface of the storage bucket, an arc groove is arranged at the bottom surface of the baffle plate, and the diameter of the discharge port is the same as that of the arc groove. When the first motor drives the baffle plate to rotate and the arc groove rotates to the bottom of the discharge port, the color powder inside the storage bucket can fall into the funnel through the discharge port and then reach the inside of the mixing bucket; when the baffle plate continues to rotate and the arc groove leaves the bottom of the discharge port, the baffle plate can seal the discharge port to stop adding color powder. In this way, not only can the production rhythm in the production process be effectively controlled to avoid the stagnation of the entire production line due to the lag of a certain link, but also unnecessary inventory and production costs can be reduced. However, the color powder finally enters the mixing bucket through the funnel, and the position of the discharge port of the funnel is fixed, so that the position where the color powder enters the mixing bucket is fixed, and the color powder is not dispersed in time when entering the mixing bucket, which will reduce the mixing speed and thus affect the preparation efficiency of the concrete. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for adding color powder to colored asphalt concrete. During the rotation of the baffle plate along with the rotating shaft, when any opening of the baffle plate rotates to face the color powder feeding port, the color powder falls onto the sieve plate through the opening, and then the push plate pushes the color powder forward. During the forward movement, the color powder is gradually dispersed and falls into the mixing bucket through the sieve holes on the sieve plate. Since the color powder is dispersed in time when entering the mixing bucket, the mixing speed can be increased, and thus the preparation efficiency of the colored asphalt concrete can be improved.

[0005] To achieve these objects and other advantages of the utility model, there is provided a device for adding color powder to colored asphalt concrete, including:

[0006] A sieve plate, which is circular and horizontally arranged, and the sieve plate faces the color powder feeding port;

[0007] A rotating shaft, which is vertically arranged, is rotatably connected to the middle of the sieve plate, and can rotate under the drive of power;

[0008] A baffle plate, which is horizontally arranged above the sieve plate. A rotating shaft passes through the baffle plate and is fixedly connected to the baffle plate. At least one opening is arranged on the baffle plate. For any one opening, when the rotating shaft drives the baffle plate to rotate, the baffle plate can rotate to make the opening face or not face the color powder feeding port. When all the openings do not face the color powder feeding port, the baffle plate seals the color powder feeding port.

[0009] A push plate, which is arranged along the radial direction of the sieve plate and is located between the sieve plate and the baffle plate. One end of the push plate is fixedly connected to the rotating shaft, and the other end extends to the edge of the sieve plate. When the push plate is located below any one opening, the push plate does not seal the opening.

[0010] Preferably, in the color asphalt concrete color powder feeding device, the baffle plate includes:

[0011] A fixing block, which is circular ring-shaped and sleeved and fixed on the rotating shaft. A mounting groove is arranged along the circumferential direction on the outer wall of the fixing block. A plurality of threaded holes are arranged along the circumferential direction on the fixing block. Each threaded hole is vertically arranged and penetrates through the top of the fixing block and communicates with the mounting groove. A bolt is inserted into each threaded hole.

[0012] A plurality of plate bodies, which are arranged at intervals along the circumferential direction of the fixing block. At least two adjacent plate bodies among the plurality of plate bodies do not contact each other. An opening is formed between any two adjacent and non-contact plate bodies. Each plate body is arc-shaped, and the centers of the circles are all coincident with the center of the fixing block. The inner end of each plate body is inserted into the mounting groove. Each plate body corresponds to at least one bolt, and the part of each plate body inserted into the mounting groove abuts against the corresponding bolt.

[0013] Preferably, in the color asphalt concrete color powder feeding device, at least two of the plurality of plate bodies have different curvatures.

[0014] Preferably, in the color asphalt concrete color powder feeding device, the curvatures of the plurality of plate bodies are all different.

[0015] Preferably, in the color asphalt concrete color powder feeding device, the top of the push plate is close to the bottom of the baffle plate.

[0016] Preferably, in the color asphalt concrete color powder feeding device, it further includes:

[0017] A cover body, which covers the sieve plate and forms an internally hollow cylindrical structure with the sieve plate. The color powder feeding port is arranged at the top of the cover body. The top of the rotating shaft passes through the top of the cover body and is connected to a driving device. The baffle plate and the push plate are both located inside the cover body.

[0018] Preferably, in the colored asphalt concrete pigment dosing device, it further includes:

[0019] A screw conveyor, which is inclined, with a first pigment inlet at the lower part and a first pigment outlet at the upper part of the screw conveyor;

[0020] A storage bucket, with a second pigment inlet at the top and a second pigment outlet at the bottom, and the second pigment outlet is communicated with the pigment dosing port.

[0021] The present utility model has at least the following beneficial effects:

[0022] During the rotation of the baffle along with the rotating shaft in the present utility model, when the baffle rotates to make any one of the openings face the pigment dosing port, the pigment falls onto the sieve plate through the opening, and then the pushing plate pushes the pigment forward. During the forward movement, the pigment gradually disperses and falls into the mixing bucket through the sieve holes on the sieve plate. Since the pigment is dispersed when entering the mixing bucket, the mixing speed can be increased, and thus the preparation efficiency of the colored asphalt concrete can be improved.

[0023] The baffle of the present utility model is composed of a fixed block and multiple plate bodies. By changing the number of plate bodies, the number and / or size of the openings can be changed, so that the dosing speed of the pigment can be adjusted.

[0029] The following further describes the present utility model in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0030] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0031] As Figures 1 to 4 shown, the present utility model provides a color powder feeding device for colored asphalt concrete, including:

[0032] A sieve plate 1, which is circular and horizontally arranged, and the sieve plate 1 is opposite to the color powder feeding port;

[0033] A rotating shaft 2, which is vertically arranged and rotatably connected to the middle of the sieve plate 1, and can rotate under the drive of power;

[0034] A baffle 3, which is horizontally arranged above the sieve plate 1, the rotating shaft 2 passes through the baffle 3 and is fixedly connected to the baffle 3, and at least one opening 301 is provided on the baffle 3; for any one opening 301, when the rotating shaft 2 drives the baffle 3 to rotate, the baffle 3 can rotate to make the opening 301 opposite or not opposite to the color powder feeding port; when all the openings 301 are not opposite to the color powder feeding port, the baffle 3 seals the color powder feeding port;

[0035] A push plate 4, which is arranged along the radial direction of the sieve plate 1 and is located between the sieve plate 1 and the baffle 3. One end of the push plate 4 is fixedly connected to the rotating shaft 2, and the other end extends to the edge of the sieve plate 1; when the push plate 4 is located below any one opening 301, the push plate 4 does not seal the opening 301. Specifically, the size of the push plate 4 can be made smaller than the size of the opening 301, so that when the opening 301 is opposite to the color powder feeding port, the push plate 4 does not seal the opening 301, and thus does not affect the falling of the color powder. That is, for the color powder to fall onto the sieve plate 1, the opening 301 needs to be opposite to the color powder feeding port. At the same time, when the opening 301 is opposite to the push plate 4, the push plate 4 does not affect the falling of the color powder.

[0036] When the color powder adding device for colored asphalt concrete provided by this solution is in use, place the sieve plate 1 above the stirring barrel 6 with an open top, or replace the top of the stirring barrel 6 with the sieve plate 1, or place the sieve plate 1, the baffle 3, the pushing plate 4 and the rotating shaft 2 inside the upper part of the stirring barrel 6. Then, drive the rotating shaft 2 to rotate by power. During the rotation of the baffle 3 with the rotating shaft 2, when any opening 301 of the baffle 3 faces the color powder feeding port, the color powder falls onto the sieve plate 1 through the opening 301. Then, the pushing plate 4 pushes the color powder forward. During the forward movement, the color powder gradually disperses and falls into the stirring barrel 6 through the sieve holes on the sieve plate 1. Since the color powder is dispersed when entering the stirring barrel 6, the mixing speed can be increased, and thus the preparation efficiency of the colored asphalt concrete can be improved.

[0037] When replacing the top of the stirring barrel 6 with the sieve plate 1, or placing the sieve plate 1, the baffle 3, the pushing plate 4 and the rotating shaft 2 inside the upper part of the stirring barrel 6, the rotating shaft 2 can extend downward into the stirring barrel 6, and stirring blades can be arranged on the part of the rotating shaft 2 located inside the stirring barrel 6 to replace the stirring components inside the stirring barrel.

[0038] As Figure 1 shown, when the top of the stirring barrel 6 is closed, and the sieve plate 1, the baffle 3, the pushing plate 4 and the rotating shaft 2 are located inside the upper part of the stirring barrel 6, the sieve plate 1 can be fixedly connected to the inner side wall of the stirring barrel 6, the color powder feeding port can be located at the top of the stirring barrel 6, and the rotating shaft 2 can pass upward through the top of the stirring barrel 6 and then be connected to the driving device.

[0039] In another solution, in the color powder adding device for colored asphalt concrete, the baffle 3 includes:

[0040] A fixing block 31, which is circular ring-shaped and sleeved and fixed on the rotating shaft 2. The center of the fixing block 31 is located on the rotating shaft 2. An installation groove is arranged along the circumferential direction on the outer wall of the fixing block 31. A plurality of threaded holes are arranged along the circumferential direction on the fixing block 31. Each threaded hole is vertically arranged and penetrates through the top of the fixing block 31 and communicates with the installation groove. A bolt is inserted into each threaded hole.

[0041] A plurality of plate bodies 32, which are arranged at intervals along the circumferential direction of the fixing block 31. At least two adjacent plate bodies 32 among the plurality of plate bodies 32 are not in contact. An opening 301 is formed between any two adjacent and non-contact plate bodies 32. Each plate body 32 is arc-shaped, and the center of each plate body 32 coincides with the center of the fixing block 31. The inner end of each plate body 32 is inserted into the installation groove. Each plate body 32 corresponds to at least one bolt, and the part of each plate body 32 inserted into the installation groove abuts against the corresponding bolt.

[0042] The baffle 3 of the present utility model is composed of a fixed block 31 and multiple plate bodies 32. By changing the number of the plate bodies 32, the number and / or size of the openings 301 can be changed, so that the feeding speed of the toner can be adjusted. When installing a certain plate body 32, insert the inner end of the plate body 32 into the installation groove, and insert a bolt through the corresponding threaded hole, and make the bottom of the bolt abut against the inner end of the plate body 32. When removing a certain plate body 32, loosen the corresponding bolt and pull out the plate body 32 outward.

[0043] In another solution, in the color asphalt concrete toner feeding device, at least two of the multiple plate bodies 32 have different curvatures.

[0044] In another solution, in the color asphalt concrete toner feeding device, the curvatures of the multiple plate bodies 32 are all different. By changing the number of the plate bodies 32 and / or using different plate bodies 32, openings 301 of more sizes can be obtained, making the device more applicable.

[0045] In another solution, in the color asphalt concrete toner feeding device, the top of the push plate 4 is close to the bottom of the baffle 3.

[0046] In another solution, in the color asphalt concrete toner feeding device, it further includes:

[0047] A cover body, which covers the sieve plate 1 and forms a hollow cylindrical structure with the sieve plate 1. The toner feeding port is arranged at the top of the cover body. The top of the rotating shaft 2 passes through the top of the cover body and is connected to a driving device. The baffle 3 and the push plate 4 are both located inside the cover body.

[0048] During actual use, the top of the stirring barrel 6 can be replaced with the sieve plate 1, so that the rotating shaft 2 extends downward into the stirring barrel 6, and stirring blades are arranged on the part of the rotating shaft 2 located inside the stirring barrel 6. At the same time, the rotating shaft 2 passes upward through the top of the cover body and is connected to the driving device.

[0049] Or the whole composed of the cover body, the sieve plate 1, the baffle 3, the push plate 4 and the rotating shaft 2 is fixed inside the upper part of the stirring barrel 6, so that the rotating shaft 2 extends downward into the stirring barrel 6, and stirring blades are arranged on the part of the rotating shaft 2 located inside the stirring barrel 6. At the same time, the rotating shaft 2 passes upward through the top of the cover body and the top of the stirring barrel 6 and is connected to the driving device.

[0050] In another solution, in the color asphalt concrete toner feeding device, it further includes:

[0051] A screw conveyor, which is inclined. A first toner inlet is arranged at the lower part of the screw conveyor, and a first toner outlet is arranged at the upper part of the screw conveyor;

[0052] The material storage bucket 5 is provided with a second toner inlet at its top and a second toner outlet at its bottom, and the second toner outlet is communicated with the toner feeding port.

[0053] When feeding toner into the material storage bucket 5, the baffle 3 is used to seal the toner feeding port. Then, the toner enters the screw conveyor through the first toner inlet, is transported upward by the screw conveyor, and finally enters the material storage bucket 5 through the first toner outlet and the second toner inlet in sequence. When the toner needs to be added, the power drives the rotating shaft 2 to rotate. During the rotation of the baffle 3 with the rotating shaft 2, when any opening 301 of the baffle 3 faces the toner feeding port, the toner falls onto the sieve plate 1 through the opening 301. Then, the pushing plate 4 pushes the toner forward, and during the forward movement, the toner gradually disperses and falls into the stirring bucket 6 through the sieve holes on the sieve plate 1.

[0054] In another solution, in the color asphalt concrete toner dosing device, a plurality of fixing rods 101 are arranged at intervals along the circumferential direction at the bottom of the sieve plate 1, each fixing rod 101 is vertically arranged, the rotating shaft 2 passes through the sieve plate 1, and at least one elastic piece 201 is arranged on the rotating shaft 2; when the rotating shaft 2 drives each elastic piece 201 to rotate, each elastic piece 201 can sequentially collide with each fixing rod 101, and each fixing rod 101 does not limit the rotation of the elastic piece 201. By fixing a plurality of fixing rods 101 at the bottom of the sieve plate 1 and the elastic piece 201 collides with the fixing rod 101 during the rotation of the rotating shaft 2, the sieve plate 1 can be vibrated, thereby avoiding the blockage of the sieve holes by the toner. The elastic piece 201 has a certain elasticity, so that the elastic piece 201 can still rotate with the rotating shaft 2 after colliding with the fixing rod 101.

[0055] In another solution, in the color asphalt concrete toner dosing device, there are two fixing rods 101 and two elastic pieces 201.
