Description

Technical Field

[0001] The utility model relates to the field of rubber powder and asphalt separation, in particular to a rubber powder and asphalt separation device. Background Art

[0002] Rubber asphalt is a modified asphalt binder material and an ideal environmentally friendly pavement material. It is mainly used in the stress absorption layer and surface layer of road structures. Rubber asphalt has greater elasticity and elastic recovery ability at high temperatures, which can improve the road surface's deformation resistance and fatigue cracking resistance; it has good high and low temperature performance, which reduces the sensitivity of asphalt to temperature. In engineering, in order to ensure the quality of asphalt, it is necessary to measure the rubber powder content of its composition. At present, the asphalt centrifugal separation method is usually used on the market to separate and extract rubber powder in asphalt, so that the rubber powder is stratified in the sedimentation tube under the action of centrifugal force, and then the staff extracts and dries the rubber powder to measure its mass to obtain the content of rubber powder in the unit volume of rubber asphalt. When the asphalt centrifugal equipment on the market is used, since asphalt is a relatively viscous liquid, it is necessary to first add a unit volume of asphalt into the test tube and stir it thoroughly to make the asphalt fully dissolved in trichloroethylene. In this process, the staff needs to stir frequently. At the same time, the determination of the rubber powder content in rubber asphalt requires multiple tests to ensure the authenticity of the results, which makes the determination of the rubber powder content in rubber asphalt take a long time and a large workload.

[0029] The driving shaft 4 is installed on the upper end of the bottom bracket 1 through a bearing. The upper end of the outer side of the driving shaft 4 is longitudinally slidably connected with the lifting cover plate 9 through a slot. The installation of the lifting cover plate 9 is convenient for the staff to control the mixing bracket 18 at the lower end of the mixing shaft 11 to be inserted into the detection bottle 5, so as to facilitate the device to fully mix the rubber asphalt and trichloroethylene. The internal annular array of the lifting cover plate 9 is penetrated by eight mixing shafts 11. The upper ends of the outer sides of the eight mixing shafts 11 are fixedly installed with transmission gears 12. The transmission gears 12 are arranged to cooperate with the transmission gear ring 10, so that when the driving shaft 4 drives the lifting cover plate 9 to rotate, the mixing shaft 11 rotates around the driving shaft 4. Since the transmission gear ring 10 cannot rotate under the action of the limiting column 7, the transmission gear 12 is meshed with the transmission gear ring 10, thereby causing the transmission gear 12 outside the mixing shaft 11 to rotate, and finally causing the mixing shaft 11 to drive the mixing bracket 18 to rotate, so that the mixing bracket 18 can mix the rubber asphalt and trichloroethylene. Vinyl chloride is stirred and mixed to enhance the practicability of the device, so that the device has the ability to synchronously test multiple test samples at the same time, and the staff does not need to frequently perform stirring operations, which greatly shortens the determination time of rubber powder content in rubber asphalt and reduces the workload of the staff.

The fixing ring 8 is welded to the limit column 7;

[0030] The rotating basket 2 is fixedly mounted on the lower end of the outside of the driving shaft 4, and a rubber card table 3 is fixedly mounted inside the rotating basket 2. Eight detection bottles 5 are arranged in a ring shape inside the rubber card table 3 through a card slot. The upper end of the detection bottle 5 is connected with a convenient rubber cover 6 through a card slot. The installation of the convenient rubber cover 6 allows the staff to only need to lift up the convenient rubber cover 6 when they need to use the mixing function of the device, and then rotate it twenty-two and a half degrees, and then put down the convenient rubber cover 6, so that the center line of the hole at the upper end of the convenient rubber cover 6 coincides with the center line of the bottle mouth of the detection bottle 5, so that the mixing bracket 18 can enter the interior of the detection bottle 5. When the mixing function of the device is no longer needed, it is only necessary to make the boss at the lower end of the convenient rubber cover 6 be sleeved on the upper end of the detection bottle 5 through the card slot to make the detection bottle 5 sealed, making the device more convenient to use and enhancing the practicality of the device.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The upper end of the limiting column 7 is equipped with a top fixing plate 16, and the top fixing plate 16 is fixedly connected to the limiting column 7. The lower end of the top fixing plate 16 is equipped with a first magnetic pad 14. The first magnetic pad 14 can absorb the transmission gear ring 10 to prevent the transmission gear ring 10 from shaking when not in use. The second magnetic pad 15 can absorb the lifting cover plate 9 so that the lifting cover plate 9 can be stably placed when not in use without interfering with the normal operation of the device. The first magnetic pad 14 is fixedly connected to the top fixing plate 16, and the lower end of the first magnetic pad 14 is equipped with a second magnetic pad. The second magnetic pad 15 is fixedly connected to the first magnetic pad 14, a guide funnel 13 is installed on the upper end of the mixing shaft 11, and the guide funnel 13 is fixedly connected to the mixing shaft 11. An anti-skid reinforcement 19 is installed inside the rotating basket 2, and the anti-skid reinforcement 19 is fixedly connected to the rotating basket 2 and the rubber card table 3. A drive motor 17 is installed on the upper end of the bottom bracket 1, and the drive motor 17 is fixedly connected to the bottom bracket 1. The drive motor 17 is connected to the drive shaft 4 through a coupling, and eight bosses are annularly arranged on the lower end surface of the convenient rubber cover 6.

[0032] The specific use process of the utility model is as follows: the staff puts eight portions of rubber asphalt per unit volume into eight test bottles 5 respectively, and then clamps the eight test bottles 5 inside the rubber clamping table 3. Next, the staff lifts up the convenient rubber cover plate 6, and then rotates it 22.5 degrees, and then puts down the convenient rubber cover plate 6, so that the center line of the hole on the upper end of the convenient rubber cover plate 6 coincides with the center line of the bottle mouth of the test bottle 5, and then the staff slides the transmission gear ring 10 downward to make the lower end face of the transmission gear ring 10 fit with the upper end face of the fixing ring 8, and then the staff The staff moves down the lifting cover plate 9, so that the mixing bracket 18 below the lifting cover plate 9 extends into the detection bottle 5, and at the same time, the transmission gear 12 is meshed with the transmission gear ring 10, and then the staff respectively adds sufficient trichloroethylene into the eight detection bottles 5 through the diversion funnel 13, and then the driving motor 17 drives the driving shaft 4 to rotate, and the driving shaft 4 drives the rotating basket 2 and the lifting cover plate 9 to rotate. When the driving shaft 4 drives the lifting cover plate 9 to rotate, the mixing shaft 11 rotates around the driving shaft 4. Because the transmission gear ring 10 cannot rotate under the action of the limit column 7, due to the transmission gear 1 2 meshes with the transmission gear ring 10, thereby rotating the transmission gear 12 outside the mixing shaft 11, and finally rotating the mixing shaft 11 to drive the mixing bracket 18 to rotate, so that the mixing bracket 18 stirs and mixes the rubber asphalt and trichloroethylene. When the rubber asphalt is fully dissolved in the trichloroethylene, the driving motor 17 loses power, and the staff moves up the transmission gear ring 10 and the lifting cover plate 9, so that the first magnetic pad 14 and the second magnetic pad 15 respectively adsorb the transmission gear ring 10 and the lifting cover plate 9, and then the staff lifts up the convenient rubber cover plate 6, and then rotates twenty-two and a half. degree, and then put down the convenient rubber cover 6, so that the boss at the lower end of the convenient rubber cover 6 is sleeved on the upper end of the detection bottle 5 through the card slot, so that the detection bottle 5 can be sealed, and then the driving motor 17 drives the rotating basket 2 to rotate, so that the rubber powder in the detection bottle 5 is separated from the trichloroethylene dissolved with asphalt under the action of centrifugal force. Finally, the staff uses a straw to take out the separated rubber powder, and uses trichloroethylene without asphalt to rinse the rubber powder. Finally, the rubber powder is dried and weighed, and the content of rubber powder in asphalt per unit volume can be calculated.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
