Description

Technical Field

[0002] Asphalt modifier refers to natural or synthetic organic or inorganic materials added to asphalt or asphalt mixture. It is a substance that can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. It is mainly divided into two categories: polymerized asphalt modifier and non-polymerized asphalt modifier. It is composed of various organic and inorganic materials. Therefore, in the production process of asphalt modifier, a mixing and proportioning device is usually required to evenly proportion and mix them. For example, as shown in an asphalt modifier proportioning and mixing device disclosed in the China Patent Network (public announcement number CN220878714U), this type of device is based on a rotating component to drive the lower hopper to rotate, and the modifier raw materials are discharged in turn, and then the transmission component drives two sets of stirring blades to rotate to fully stir and mix the modifier.

[0003] However, the proportioning and mixing devices for asphalt modifier production adopted by the above-mentioned public patents and the existing market still have some shortcomings: the existing method of feeding the modifier raw materials one by one and stirring and mixing them with stirring blades can only perform stirring work at a single horizontal level, and the upper and lower layers of raw materials cannot be fully stirred and mixed. The quality of the modifier proportioning and mixing is not efficient enough, and the raw materials are easily wrapped and gathered into agglomerates. To this end, those skilled in the art provide a proportioning and mixing device for asphalt modifier production to solve the problems raised in the above background technology. Utility Model Content

[0024] Please refer to Figure 1-4As shown, a proportioning and mixing device for the production of asphalt modifiers includes a mixing tank 1, and a rotary push dispersing mechanism is arranged on the upper end of the tank body of the mixing tank 1. The rotary push dispersing mechanism includes a first brake motor 2 installed on the upper end of the tank body of the mixing tank 1, and a rotating shaft 6 is arranged at the output end of the first brake motor 2, and a rotary push impeller 7 is arranged at the bottom end of the shaft of the rotating shaft 6. A plurality of feed valves 4 are installed on the upper end of the tank body of the mixing tank 1 along the rotation direction of the rotary push impeller 7. When the asphalt modifier is proportioned and mixed for production, the asphalt modifier raw materials are fed into the mixing tank 1 one by one through the feed valves 4, and at the same time, based on the first brake motor 2 as a power source, the combined rotation of the rotating shaft 6 and the rotary push impeller 7 is driven to perform rotary push centrifugal dispersion on the fed modifier raw materials, so that various raw materials are preliminarily proportioned and mixed.

[0025] A stirring and proportioning mechanism is arranged at the lower end of the tank body of the mixing tank 1, and the stirring and proportioning mechanism includes a second brake motor 3 installed at the lower end of the tank body of the mixing tank 1 and a transmission seat 10 built into the tank body of the mixing tank 1. The output end of the second brake motor 3 is provided with a vertical transmission shaft 8 that passes through the transmission seat 10, and the support of the transmission seat 10 is provided with multiple groups of horizontal transmission shafts 11 arranged along its circumference. A bevel gear A14 is arranged in the middle of the shaft of the vertical transmission shaft 8, and a bevel gear A14 is arranged inside the support of the built-in transmission seat 10. A bevel gear B15 meshing with the bevel gear A14 is arranged at one end of the shaft of the horizontal transmission shaft 11. After the feed of the modifier raw material is completed, based on the second brake motor 3 as the power source, the vertical transmission shaft 8 is driven to rotate, and then the bevel gear A14 is driven to rotate. The meshing transmission of the bevel gear A14 and the bevel gear B15 is used to drive the horizontal transmission shaft 11 to operate in conjunction, and the corresponding components are controlled to operate in conjunction, so as to stir and mix the modifier raw material.

[0026] A plurality of first stirring impellers 9 are arranged on the upper half of the shaft of the vertical transmission shaft 8, and a plurality of second stirring impellers 12 are arranged on the outer side of the shaft of the horizontal transmission shaft 11. The blades of the first stirring impeller 9 and the second stirring impeller 12 are symmetrically arranged at a vertical angle. When the vertical transmission shaft 8 rotates, the first stirring impeller 9 is driven to rotate to stir and mix the modifier raw materials in the horizontal direction. When the horizontal transmission shaft 11 rotates, the second stirring impeller 12 is driven to rotate to stir and mix the modifier raw materials in the vertical direction, and the modifier raw materials at the bottom layer are turned over and pushed up to be fully combined and stirred with the upper layer of modifier raw materials stirred horizontally, thereby ensuring the sufficient stirring and mixing ratio performance of the modifier raw materials.

[0027] The bottom end of the shaft of the vertical transmission shaft 8 is provided with a stirring scraper 13 that fits against the wall of the mixing tank 1. The bottom of the mixing tank 1 is symmetrically connected and equipped with a discharge valve 5 opposite to the stirring scraper 13, and the bottom of the mixing tank 1 is a sloped inclined surface structure. When the vertical transmission shaft 8 rotates, the stirring scraper 13 is driven to rotate synchronously. On the one hand, it drives the modifier raw material at the bottom to be stirred, so as to facilitate the upward stirring of the modifier raw material at the bottom. On the other hand, it can be used as a scraping and cleaning component. After the modifier raw material is mixed, it is scraped and driven to be completely discharged through the discharge valve 5.

[0028] The working principle of the utility model is as follows: when the asphalt modifier is mixed and produced, the asphalt modifier raw material is fed into the mixing tank 1 through the feed valve 4, and at the same time, based on the first brake motor 2 as the power source, the combination of the rotating shaft 6 and the rotary impeller 7 is driven to rotate, and the fed modifier raw material is subjected to rotary centrifugal dispersion to make various raw materials preliminarily mixed in proportion;

[0029] Further, after the feeding of the modifier raw material is completed, based on the second brake motor 3 as a power source, the vertical transmission shaft 8 is driven to rotate, and then the bevel gear A14 is driven to rotate. The meshing transmission of the bevel gear A14 and the bevel gear B15 is used to drive the horizontal transmission shaft 11 to operate in conjunction. When the vertical transmission shaft 8 rotates, the first stirring impeller 9 is driven to rotate to stir and mix the modifier raw material in the horizontal direction. When the horizontal transmission shaft 11 rotates, the second stirring impeller 12 is driven to rotate to stir and mix the modifier raw material in the vertical direction, and the modifier raw material at the bottom layer is turned over and pushed up to be fully combined and stirred with the upper layer of the modifier raw material stirred horizontally;

[0030] After the modifier raw materials are mixed and proportioned, the discharge valve 5 is opened to discharge the modifier, and the bottom modifier is scraped and driven by the stirring scraper 13 to completely discharge the modifier through the discharge valve 5.
