[0002] Road pothole repair accounts for a very high proportion in daily road maintenance operations. Asphalt hot mix has certain limitations in production and transportation, so asphalt cold mix, which is simpler and more convenient to operate, has also been more widely used. Specifically, asphalt cold mix usually refers to a mixture formed by mixing unheated mineral materials (aggregates) and diluted asphalt. According to the mixing form, it can be divided into two types: factory mixing and on-site mixing. Before 1998, there was no real cold patch material in my country's urban road projects. There were only water-based emulsified asphalt materials for room temperature repair. After 2000, cold mix has been promoted and applied on national highways, provincial highways, and municipal roads as a product with high technological content.
[0003] As one of the main maintenance entities of Guizhou Province's expressways, the applicant has conducted extensive research on the maintenance of Guizhou Province's expressways and participated in the construction and maintenance of most maintenance sites.
[0004] Taking the Fengxiang maintenance base as an example, the original design of the Fengxiang station was mainly based on the production of recycled asphalt pavement (RAP) materials. Taking into account the versatility of equipment and processes, as well as the research results of the applicant's R&D personnel, if the existing RAP material production equipment is modified, the station can be equipped with cold mix production capabilities at the lowest cost, which can greatly reduce the maintenance costs of highways in the province.

[0017] In order to have a clearer understanding of the technical features, purpose and effects of the utility model, the specific implementation of the utility model is now described with reference to the accompanying drawings, wherein the same components are marked with the same reference numerals.
[0018] Figure 1 FIG. 1 is a schematic diagram of the structural principle of a cold mix production device according to a specific embodiment of the utility model; see Figure 1 As shown, the utility model provides a cold mix production device, which includes an asphalt tank 1, a cold replenishment liquid preparation tank 2, and a cold mix mixing tank 3. The asphalt tank 1 is connected to the cold replenishment liquid preparation tank 2 through a pipeline, and the cold replenishment liquid preparation tank 2 is connected to the cold mix mixing tank 3 through a pipeline. An aggregate delivery port is arranged on the top of the cold mix mixing tank 3, and the cold mix mixing tank 3 is connected to a diesel tank 4 through a pipeline. The cold mix mixing tank 3 is detachably connected to a cold replenishment agent delivery pump 21 through a pipeline.
[0019] As described in the background technology section, the technical solution provided by this application is aimed at enabling the station to have the ability to produce cold mix materials at the lowest cost through transformation based on the existing RAP material production equipment at the station. Specifically, the applicant's R&D team has developed a cold replenishment liquid for the production of cold mix materials based on the oilstone separation aggregate produced by the existing RAP material production line. The formula of the cold replenishment liquid is asphalt: diesel: cold replenishment agent = 97%: 20%: 3%. In other words, the asphalt tank 1 can be the existing asphalt tank at the station, and the cold mix mixing tank 3 can also be the mixing equipment already in the RAP material production line at the station. It is only necessary to add the cold replenishment liquid preparation tank 2 and the diesel tank 4, and then add pipelines to connect the cold replenishment liquid preparation tank 2 with the asphalt tank 1 and the cold mix mixing tank 3 respectively, so as to realize the production of cold mix materials.
[0020] Figure 2 for Figure 1 Schematic diagram of the structure principle of the cold make-up liquid mixing tank; see Figure 2 As shown, an agitator 22 is provided in the cold replenishment liquid preparation tank 2, and a first pipe 201 for connecting to the asphalt tank 1, a second pipe 202 for connecting to the diesel tank 4, and a third pipe 203 for connecting to the cold replenishment agent delivery pump 21 are provided on the top of the cold replenishment liquid preparation tank 2. A working pump 23 is connected to the bottom of the cold replenishment liquid preparation tank 2, and a three-way valve 24 is connected to the rear end of the working pump 23. The three-way valve 24 is respectively connected to a pipe for connecting to the cold mix mixing tank 3 and a fourth pipe 204 connected to the top of the cold replenishment liquid preparation tank 2.
[0021] After the three materials of asphalt, diesel and cold patch are evenly mixed in the cold patching liquid preparation tank 2 (usually for not less than 2 hours), they can be transported to the cold mix mixing tank 3 through the working pump 23 to mix and mix with aggregates to produce cold mix. Since the production of cold mix is intermittent, that is, each time the cold patching liquid and aggregates are input into the cold mix mixing tank 3, it is necessary to wait until this batch of cold patching liquid and aggregates are fully mixed, and after the cold mix is produced and exported, a new round of cold patching liquid and aggregates are input. Therefore, during the operation of the cold mix mixing tank 3, the cold patching liquid can be refluxed to the cold patching liquid preparation tank 2 through the fourth pipeline 204 through the three-way valve 24, which can ensure the fluidity of the cold patching liquid on the one hand, and make the remaining cold patching liquid more fully mixed on the other hand.
[0022] Specifically, the cold replenishment solution preparation tank 2 used in the Liquidambar maintenance base has a diameter of about 2.2 meters and a height of about 2.5 meters.
[0023] The agitator 22 is used to ensure that the materials transported into the cold replenishment liquid preparation tank 2 are mixed evenly. Figure 4 for Figure 2 Schematic diagram of the structural principle of a set of blades of a stirrer, see Figure 2 and Figure 4 As shown, in this embodiment, the agitator 22 includes two groups of blades spaced 90 degrees circumferentially and about one-third of the height of the cold replenishment fluid preparation tank 2 axially, and each group of blades includes two blades 221 arranged 180 degrees circumferentially.
[0024] The diesel tank 4 is used to store diesel fuel. The diesel fuel can be transported to the cold replenishment liquid mixing tank 2 through the second pipeline 202 .
[0025] The cold repair agent delivery pump 21 can be detachably connected to the third pipeline 203 through a hose. When the purchased cold repair agent is packaged in a large barrel, the suction pipe of the cold repair agent delivery pump 21 can be inserted into the packaging barrel of the cold repair agent to draw the cold repair agent into the cold repair liquid preparation tank 2.
[0026] When the purchased cold filler is not packaged in large barrels but in small sizes, refer to Figure 2 As shown, a base 25 can be built next to the cold replenishment liquid preparation tank 2, and then a cold replenishment agent buffer barrel 26 can be provided, so that the cold replenishment agent in small packages can be poured into the cold replenishment agent buffer barrel 26 first, and then the cold replenishment agent delivery pump 21 can be used to input the cold replenishment agent in the cold replenishment agent buffer barrel 26 into the cold replenishment liquid preparation tank 2.
[0027] Figure 3 for Figure 2 Schematic diagram of the three-dimensional structure principle of the intercooler supplementary agent buffer barrel, see Figure 3 and Figure 2 As shown, a liquid outlet pipe 261 is provided at the bottom of the cold supplement agent buffer barrel 26, so that a plurality of small packages of cold supplement agents can be poured into the cold supplement agent buffer barrel 26, and then all the cold supplement agents in the cold supplement agent buffer barrel 26 can be input into the cold supplement liquid preparation tank 2 by simply connecting the suction pipe of the cold supplement agent delivery pump 21 to the liquid outlet pipe 261. In order to reserve assembly space for the liquid outlet pipe 261, see Figure 2 As shown, a base 25 can be built beside the cold replenishment liquid preparation tank 2. When the cold replenishment agent buffer barrel 26 is placed on the base 25, the liquid outlet pipe 261 can be staggered and placed beside the base 25, which is convenient for connecting the suction pipe of the cold replenishment agent delivery pump 21 with the liquid outlet pipe 261. The base 25 can be a fixed component built with bricks and cement, or a movable component with a main structure welded with metal rods and wooden boards laid on it.
[0028] The cold mix production device provided by the utility model can make full use of the existing RAP material production equipment and can provide cold mix production capacity by adding only a few structures and pipelines at a relatively low cost, thereby greatly improving the utilization efficiency of existing stations and reducing the comprehensive use cost of the stations.
