Description

Technical Field

[0001] The utility model relates to the technical field of asphalt emulsification production, in particular to high-viscosity emulsified asphalt production equipment. Background Art

[0002] Asphalt is a black or brown colloidal substance composed primarily of hydrocarbons and their non-metallic derivatives. It is a complex mixture separated from crude oil during the refining process. Asphalt has viscous and lubricating properties and is widely used in road construction, waterproofing projects, anti-corrosion projects, coatings, adhesives and other fields. By selecting the appropriate asphalt type and application method, the quality and performance of the project can be improved to meet the application needs of different industries.

[0003] Regarding the production equipment of high-viscosity emulsified asphalt, it was found through searching that the publication number CN216321575U discloses an emulsification device for asphalt production. The utility model is provided with a heating chamber, and the emulsifier in the heating chamber is heated by a first heating plate and then discharged into the stirring chamber to be stirred and fused with the asphalt. This is beneficial to prevent the moisture in the emulsifier from directly vaporizing when encountering high-temperature asphalt, and to avoid inaccurate asphalt emulsification ratio leading to a decrease in asphalt quality. A central shaft is provided, and the central shaft rotates through the second rotating shaft driven by the second motor, thereby driving the second stirring rod on the central shaft to rotate. The central shaft and the second stirring rod are respectively fixedly connected with a second heating plate and a heating rod, which is beneficial to heating the asphalt while stirring the asphalt, and is beneficial to better mixing the asphalt and emulsifier, thereby improving the asphalt emulsification efficiency. However, there are defects and shortcomings in the actual use of the emulsification device for asphalt production. The solenoid valve is located in the stirring chamber. First, the stirring chamber is continuously heated and stirred. The solenoid valve is in a closed space with poor heat dissipation effect, and is easily damaged by long-term heat. Second, when the raw materials for asphalt production are added to the stirring chamber, an observation window is set on the outside of the asphalt production box, which makes it unclear how much is added. If too much is added, the raw materials will submerge the solenoid valve, affecting the normal use of the solenoid valve, resulting in the emulsifier not being able to be discharged normally into the stirring chamber to mix with the raw materials. The solenoid valve is easily damaged, which increases the cost of asphalt emulsification production and is inconvenient for maintenance and replacement.

[0004] After the emulsifier and raw materials are mixed and stirred in the stirring chamber, the centrifugal force generated by the rotation and stirring will cause the emulsified asphalt to remain and adhere to the inner wall of the asphalt production box, making it inconvenient to clean it, resulting in asphalt waste. After the inner wall solidifies and the amount increases, it will also affect the normal use of the asphalt production box. Utility Model Content

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0025] like Figure 1-Figure 5 As shown, a high-viscosity emulsified asphalt production equipment includes: an asphalt production tank body 1, a plurality of stirring rods 101 arranged inside the asphalt production tank body 1, a feed hopper a102 installed on the top of the asphalt production tank body 1, an equipment box 2 installed on one side of the outer end of the asphalt production tank body 1, a cleaning component arranged on both sides of the interior of the asphalt production tank body 1, the cleaning component including: a cleaning scraper 109, a scraper blade 110, a connecting rod 111 and a mounting block 112, a preheating component arranged inside the equipment box 2, the preheating component including: a preheating tank 201, a heating box 203, a heating plate 204 and a feed pump 205.

[0026] Among them, a preheating tank 201 is installed inside the equipment box 2, a feed hopper b202 is installed on the top of the preheating tank 201, heating boxes 203 are installed on both sides of the outer end of the preheating tank 201, a heating plate 204 is installed inside the heating box 203, a feed pump 205 is installed on one side of the equipment box 2, a pumping pipe is installed between the feed pump 205 and the preheating tank 201, and a delivery pipe 206 is installed between the feed pump 205 and the asphalt production tank body 1.

[0027] When the emulsifier is used, first add the emulsifier from the feed hopper b202 into the preheating tank 201, start the heating plate 204 inside the heating box 203, and the temperature of the heating plate 204 will gradually increase, transferring the heat to the inside of the preheating tank 201, preheating the emulsifier inside the preheating tank 201, so that the emulsifier has temperature and is in a hot melt state, which can prevent the water in the emulsifier from being directly vaporized when it encounters high-temperature asphalt, and avoid the asphalt emulsification ratio being inaccurate, which will lead to the decline of asphalt quality. In addition, the preheating structure is separated from the stirring chamber. The partition setting can provide protection for the preheating structure to avoid easy damage and increase in production costs. It can also facilitate the inspection and maintenance of the preheating structure and is convenient for use in the asphalt emulsification production process. After the emulsifier is preheated, the feed pump 205 is started to generate negative pressure in the extraction pipe to suck and extract the emulsifier raw material, and discharge it into the delivery pipe 206 through the feed pump 205. The emulsifier raw material is transported from the delivery pipe 206 to the inside of the asphalt production tank 1 to mix with the raw material for producing asphalt, which helps to better mix the asphalt raw material and the emulsifier.

[0028] Among them, a servo motor 103 is installed at the bottom of the asphalt production tank body 1, and a motor shaft 104 connected to the servo motor 103 is provided inside the asphalt production tank body 1, and the top of the motor shaft 104 is rotatably connected to the top of the inner part of the asphalt production tank body 1 through a bearing, and a protective tube 105 is installed outside the motor shaft 104, and multiple stirring rods 101 are installed on both sides of the outer end of the protective tube 105. A circular heating box 106 is installed outside the asphalt production tank body 1, and multiple heating coils 107 wound and connected to the asphalt production tank body 1 are provided inside the circular heating box 106.

[0029] During asphalt emulsion production, the raw materials for asphalt production are added from the feed hopper a102 into the asphalt production tank body 1, so that the raw materials are in contact with the multiple stirring rods 101 inside the asphalt production tank body 1, and the servo motor 103 and the heating coil 107 are started. The servo motor 103 drives the motor shaft 104 to rotate, and the motor shaft 104 drives the protective tube 105 and the multiple stirring rods 101 to rotate at the same time to stir the raw materials. After the heating coil 107 starts working, the heat slowly rises and conducts heat to the inside of the asphalt production tank body 1, heating the various raw materials to make them fuse together, and the preheated emulsifier is discharged from the conveying pipe 206 into the asphalt production tank body 1, mixed with the raw materials, and the emulsifier and raw materials are stirred and mixed evenly through the multiple stirring rods 101, thereby improving the asphalt emulsification production efficiency.

[0030] Among them, an insulation layer 108 is provided inside the circular heating box 106, and the insulation layer 108 is filled with insulation cotton. The insulation layer 108 is located outside the heating coil 107. During the use of the heating coil 107 to heat the interior of the asphalt production tank 1, the setting of the insulation layer 108 can prevent the heat inside the circular heating box 106 from being easily lost, thereby improving the utilization rate of heat and reducing electricity costs.

[0031] Among them, a discharge pipe 3 is installed on one side of the bottom of the asphalt production tank body 1, and an electromagnetic valve 301 is installed on the discharge pipe 3. A temperature sensor 4 is installed at the bottom end of the asphalt production tank body 1. During the asphalt emulsification production process inside the asphalt production tank body 1, the temperature of the asphalt can be detected by the temperature sensor 4, so that the staff can know the degree of asphalt emulsification. After the asphalt emulsification production inside the asphalt production tank body 1 is completed, the electromagnetic valve 301 is started to open, and a collection container is placed outside the discharge pipe 3, so that the asphalt can be discharged from the outside of the asphalt production tank body 1 for use.

[0032] Among them, when the equipment box 2 is in use, a control panel is fixedly installed on the box door outside the equipment box 2, and a display screen and multiple control buttons are installed on the outside of the control panel. A power cord connected to the control panel is installed on the side of the equipment box 2, and the servo motor 103, heating coil 107, heating plate 204, feeding pump 205, solenoid valve 301 and temperature sensor 4 are connected to the control panel through wires. The length of the power cord is two meters. A plug is installed at the other end of the power cord, which can be inserted into the socket in the production workshop to connect to the power supply, so that the control panel, servo motor 103, heating coil 107, heating plate 204, feeding pump 205, solenoid valve 301 and temperature sensor 4 are normally powered and used. The servo motor 103, heating coil 107, heating plate 204, feeding pump 205, solenoid valve 301 and temperature sensor 4 can be controlled to start and stop through the control panel. The temperature of the asphalt detected by the temperature sensor 4 can be displayed on the display screen for the staff to watch. The control program involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the utility model.

[0033] Among them, cleaning scrapers 109 are provided on both sides of the inner wall of the asphalt production tank body 1, and scrapers 110 are installed at both ends of the cleaning scraper 109. Connecting rods 111 are installed at the outer ends of multiple stirring rods 101, and mounting blocks 112 are installed between the connecting rods 111 and the cleaning scraper 109. During the stirring process of raw materials and emulsifiers inside the asphalt production tank body 1, some of the raw materials and emulsifiers will adhere to the inner wall of the asphalt production tank body 1. When the multiple stirring rods 101 are stirring, the connecting rods 111, the mounting blocks 112 and the cleaning scraper 109 will also be driven to rotate. The raw materials and emulsifiers adhered to the inner wall will be scraped off by the cleaning scraper 109 and the scrapers 110 at both ends of the cleaning scraper 109, which is conducive to uniform mixing of the raw materials and emulsifiers. When the asphalt production tank body 1 is discharged for use, the asphalt on the inner wall of the asphalt production tank body 1 can also be scraped off and cleaned, avoiding waste of asphalt, and thus preventing the asphalt from solidifying on the inner wall and affecting the normal use of the asphalt production tank body 1.

[0034] Among them, the cleaning scraper 109 is arranged in an arc-shaped structure, and the cleaning scraper 109 is in contact with the inner wall of the asphalt production tank body 1. When the cleaning scraper 109 is in use, since the cleaning scraper 109 is arranged in an arc-shaped structure, the cleaning scraper 109 can be consistent with the curvature of the inner wall of the asphalt production tank body 1, ensuring that the cleaning scraper 109 is in contact with the inner wall of the asphalt production tank body 1, and can scrape off the residual asphalt on the inner wall of the asphalt production tank body 1.

[0035] Working principle:

[0036] When the emulsifier is used, first add the emulsifier from the feed hopper b202 into the preheating tank 201, start the heating plate 204 inside the heating box 203, and the temperature of the heating plate 204 will gradually increase, transferring the heat to the inside of the preheating tank 201, preheating the emulsifier inside the preheating tank 201, so that the emulsifier has temperature and is in a hot melt state, which can prevent the water in the emulsifier from being directly vaporized when it encounters high-temperature asphalt, and avoid the asphalt emulsification ratio being inaccurate, which will lead to the decline of asphalt quality. In addition, the preheating structure is separated from the stirring chamber. The partition setting can provide protection for the preheating structure to avoid easy damage and increase in production costs. It can also facilitate the inspection and maintenance of the preheating structure and is convenient for use in the asphalt emulsification production process. After the emulsifier is preheated, the feed pump 205 is started to generate negative pressure in the extraction pipe to suck and extract the emulsifier raw material, and discharge it into the delivery pipe 206 through the feed pump 205. The emulsifier raw material is transported from the delivery pipe 206 to the inside of the asphalt production tank 1 to mix with the raw material for producing asphalt, which helps to better mix the asphalt raw material and the emulsifier.

[0037] During asphalt emulsion production, the raw materials for asphalt production are added from the feed hopper a102 into the asphalt production tank body 1, so that the raw materials are in contact with the multiple stirring rods 101 inside the asphalt production tank body 1, and the servo motor 103 and the heating coil 107 are started. The servo motor 103 drives the motor shaft 104 to rotate, and the motor shaft 104 drives the protective tube 105 and the multiple stirring rods 101 to rotate at the same time to stir the raw materials. After the heating coil 107 starts working, the heat slowly rises and conducts heat to the inside of the asphalt production tank body 1, heating the various raw materials to make them fuse together, and the preheated emulsifier is discharged from the conveying pipe 206 into the asphalt production tank body 1, mixed with the raw materials, and the emulsifier and raw materials are stirred and mixed evenly through the multiple stirring rods 101, thereby improving the asphalt emulsification production efficiency.

[0038] During the stirring process of the raw materials and emulsifier inside the asphalt production tank body 1, some of the raw materials and emulsifier will adhere to the inner wall of the asphalt production tank body 1. When the multiple stirring rods 101 are stirring, the connecting rod 111, the mounting block 112 and the cleaning scraper 109 will also be driven to rotate. The raw materials and emulsifier adhered to the inner wall will be scraped off by the cleaning scraper 109 and the scrapers 110 at both ends of the cleaning scraper 109, which is conducive to uniform mixing of the raw materials and emulsifier. When the asphalt production tank body 1 is discharged for use, the asphalt on the inner wall of the asphalt production tank body 1 can also be scraped off and cleaned, thereby avoiding waste of asphalt and preventing the asphalt from solidifying on the inner wall and affecting the normal use of the asphalt production tank body 1.
