Description

Technical Field

[0001] This utility model relates to the field of asphalt addition equipment technology, specifically to an emulsified asphalt addition device. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, often existing in liquid or semi-solid petroleum form, with a black surface. It is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material. In the production process of water-stabilized asphalt conversion emulsified asphalt cold recycling mixing plants, asphalt additive devices are required to add asphalt.

[0003] In existing asphalt mixing plants, there are some problems with the asphalt additive equipment when adding emulsified asphalt. Due to the poor fluidity of emulsified asphalt, the emulsified asphalt in the asphalt additive equipment is discharged from the discharge pipe at an extremely slow speed, resulting in insufficient asphalt additive efficiency. Furthermore, during the flow process, the high viscosity of the emulsified asphalt causes it to remain inside the feed cylinder, which not only wastes the emulsified asphalt but also reduces its utilization rate. Summary of the Invention

[0004] The purpose of this invention is to provide an emulsified asphalt addition device to solve the problems of insufficient emulsified asphalt outflow rate and emulsified asphalt residue in the material cylinder in the prior art, which reduces the utilization rate of emulsified asphalt.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An emulsified asphalt adding device includes: a material cylinder with an inlet installed on its side wall and an outlet installed at its bottom, the inlet and outlet being used for inputting and outputting emulsified asphalt, respectively; a lifting assembly and a scraping assembly, the scraping assembly being located inside the material cylinder; a through hole is formed at the top of the material cylinder, one end of the lifting assembly passing through the through hole and connected to the scraping assembly, the lifting assembly being configured to drive the scraping assembly to move up and down inside the material cylinder; the scraping assembly is in contact with the inner wall of the material cylinder, and during the descent of the scraping assembly, it can squeeze the emulsified asphalt inside the material cylinder and scrape off the emulsified asphalt on the side wall of the material cylinder.

[0007] Based on the aforementioned technical means, by setting up a lifting component, the scraper component is located inside the material cylinder and connected to the lifting component. During the descent of the lifting component, it can drive the scraper component to descend, and the scraper component is in close contact with the inner wall of the material cylinder. This allows the scraper component to squeeze the emulsified asphalt during its descent, enabling the emulsified asphalt in the material cylinder to flow out more quickly, increasing the discharge speed of the emulsified asphalt, thereby improving the overall asphalt addition efficiency and reducing construction time. At the same time, during the descent of the scraper component, it can also scrape off the emulsified asphalt on the side wall of the material cylinder, preventing the emulsified asphalt from depositing inside the material cylinder, avoiding pipe blockage caused by deposits, and improving the reliability and service life of the equipment.

[0008] Furthermore, the lifting assembly includes a screw, a nut, and a turntable. The screw and the nut are threaded together, the screw passes through the through hole, and the nut is fixed to the material cylinder. The turntable is fixed to the top of the screw, and the scraping assembly is installed at the bottom of the screw.

[0009] According to the above technical means, the lifting assembly includes a nut and a screw. During the spiral rotation of the screw and nut, it can rise or fall along its length. The scraper assembly is installed at the bottom of the screw, so that during the movement of the screw, it can drive the scraper assembly to rise or fall along the length of the screw. During the descent of the scraper assembly, it can squeeze the emulsified asphalt in the barrel. Because the scraper assembly is in close contact with the inner wall of the barrel, it can scrape off the emulsified asphalt occupying the inner wall of the barrel during the descent. The cooperation between the nut and the screw reduces the shaking and deviation of the screw during the movement, improves the stability and reliability of the equipment, reduces the occurrence of mechanical failures, extends the service life of the equipment, and improves the durability of the equipment.

[0010] Furthermore, the scraping assembly includes a scraper disc, which is installed at the bottom end of the screw. The screw can drive the scraper disc to rise and fall inside the material cylinder. The scraper disc is in contact with the side wall of the material cylinder so that it can squeeze the emulsified asphalt and scrape off the emulsified asphalt from the side wall of the material cylinder during the descent of the scraper disc.

[0011] According to the above technical means, the scraping component includes a scraper, which is installed at the bottom of the screw. The screw can drive the scraper to rise and fall inside the barrel. During the descent of the scraper inside the barrel, it can squeeze the emulsified asphalt inside the barrel, accelerate the flow rate of the emulsified asphalt, and reduce the construction time. Since the emulsified asphalt is highly viscous, some of it will stick to the inner wall of the barrel during the flow process. The scraper is in contact with the side wall of the barrel. During the descent of the scraper inside the barrel, it can scrape off the emulsified asphalt stuck to the inner wall of the barrel, thereby increasing the utilization rate of the emulsified asphalt.

[0012] Furthermore, it also includes a rotating shaft, the screw is a hollow screw, and the rotating shaft passes through the screw; the scraping assembly also includes a scraper, the scraper is located below the scraper disc; the rotating shaft passes through the scraper disc and is connected to the scraper, the rotating shaft is used to drive the scraper to rotate, so as to scrape off the emulsified asphalt at the bottom of the material cylinder.

[0013] According to the above technical means, the scraping assembly also includes a scraper, which is located below the scraper disc, and the rotating shaft passes through the scraper disc and is connected to the scraper. During the rotation of the rotating shaft, the scraper will be driven to rotate. At this time, the scraper can scrape off the emulsified asphalt at the bottom of the material cylinder, the inner wall of the material cylinder, and the bottom of the scraper disc. At the same time, the scraper can throw off the emulsified asphalt remaining on the scraper during the rotation, which increases the utilization rate of emulsified asphalt and further reduces costs.

[0014] Furthermore, it also includes a drive motor, which is connected to the rotating shaft to drive the rotating shaft to rotate.

[0015] According to the above technical means, by setting a drive motor and driving the drive motor to drive the rotating shaft, the drive motor drives the rotating shaft to rotate and thus drives the scraper to rotate, which can provide stable and controllable power, ensuring that the rotation of the scraper is more uniform and efficient, thereby improving the scraping efficiency and reducing the residue of emulsified asphalt in the material barrel. The drive motor can control the rotation speed of the scraper to ensure that the residual emulsified asphalt on the scraper can be thrown off during the rotation of the scraper.

[0016] Furthermore, it also includes a first bracket, through which the drive motor is mounted on the turntable.

[0017] According to the above technical means, by setting up the first bracket, the drive motor can be stably installed on the turntable, preventing the drive motor from shaking and becoming unstable during the rotation of the turntable, thus improving the stability of the device and the safety of operators during the process.

[0018] Furthermore, the lifting assembly also includes a fixing sleeve, and the screw is connected to the scraper through the fixing sleeve.

[0019] According to the above technical means, the screw can be connected to the scraper through the fixed sleeve, so that the fixed sleeve moves along the length of the screw during the rotation of the screw, thereby driving the scraper to move, which increases the stability of the scraper and the screw.

[0020] Furthermore, the lifting assembly also includes a rotating handle, which is mounted on the turntable along the circumferential direction of the turntable.

[0021] Based on the aforementioned technical means, the design of the rotary handle allows operators to more easily rotate the moving rod and adjust the position of the screw, improving the convenience and efficiency of operation. The rotary handle design simplifies the operation process, reducing equipment failures caused by improper operation, lowering equipment maintenance costs, and improving the economic efficiency of the equipment.

[0022] Furthermore, it also includes a first valve and a second valve. The first valve is installed on the feed inlet and is used to control the opening and closing of the feed inlet; the second valve is installed on the discharge outlet and is used to control the opening and closing of the discharge outlet.

[0023] Based on the above-mentioned technical means, a first valve and a second valve are installed at the discharge port and the inlet, respectively. By controlling the opening and closing of the first valve and the second valve, the input and output of emulsified asphalt can be precisely controlled, avoiding leakage and waste of emulsified asphalt, reducing environmental pollution and safety hazards, and improving the efficiency and safety of the equipment.

[0024] Furthermore, it also includes a second bracket, which is mounted on the material cylinder to support the material cylinder.

[0025] Based on the above technical means, the installation of the second support can ensure that the material cylinder remains stable during operation, reduce emulsified asphalt leakage or equipment damage caused by the shaking or instability of the material cylinder, and improve the stability and reliability of the material cylinder; the installation of the second support can reduce safety accidents caused by the instability of the material cylinder and improve the safety of the material cylinder, especially during the operation of the material cylinder, ensuring the safety of operators and the material cylinder.

[0026] The beneficial effects of this utility model are:

[0027] By incorporating a lifting assembly, the scraper assembly is located inside the material cylinder and connected to the lifting assembly. During its descent, the lifting assembly drives the scraper assembly downward, and the scraper assembly adheres to the inner wall of the material cylinder. This allows the scraper assembly to squeeze the emulsified asphalt during its descent, accelerating the outflow of the emulsified asphalt from the material cylinder and increasing the discharge speed. This, in turn, improves the overall asphalt addition efficiency and reduces construction time. Simultaneously, the scraper assembly can also scrape off the emulsified asphalt from the side wall of the material cylinder during its descent, preventing the emulsified asphalt from depositing inside the cylinder and avoiding pipe blockage caused by deposits. This improves the reliability and service life of the equipment. Attached Figure Description

[0036] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0038] like Figure 1 and Figure 3 As shown, this embodiment proposes an emulsified asphalt adding device, including: a material cylinder 1, with an inlet 2 installed on the side wall of the material cylinder 1 and an outlet 3 installed at the bottom of the material cylinder 1, the inlet 2 and the outlet 3 being used for inputting and outputting emulsified asphalt respectively; a lifting component 4 and a scraping component 5, the scraping component 5 being located inside the material cylinder 1; a through hole 1-1 is formed at the top of the material cylinder 1, one end of the lifting component 4 passes through the through hole 1-1 and is connected to the scraping component 5, the lifting component 4 being configured to drive the scraping component 5 to move up and down inside the material cylinder 1; the scraping component 5 is in contact with the inner wall of the material cylinder 1, and during the descent of the scraping component 5, it can squeeze the emulsified asphalt inside the material cylinder 1 and scrape off the emulsified asphalt on the side wall of the material cylinder 1.

[0039] like Figure 1 and Figure 3As shown, the usage process of this embodiment is as follows: First, the lifting component 4 raises the scraper component 5 to the top of the material cylinder 1, and the scraper component 5 is located inside the material cylinder 1. Then, the emulsified asphalt is fed into the material cylinder 1 through the feed inlet 2. When the material cylinder 1 is full of emulsified asphalt, the lifting component 4 descends. During the descent of the lifting component 4, the scraper component 5 is driven to descend until the top and bottom of the scraper component are in contact with the bottom of the lifting component 4 and the bottom of the material cylinder 1, respectively. At this point, the lifting component 4 stops descending. Since the scraper component 5 is in contact with the inner wall of the material cylinder 1, the descent of the scraper component 5 can squeeze the emulsified asphalt in the material cylinder 1 and scrape off the emulsified asphalt on the side wall of the material cylinder 1, thereby improving the utilization rate and discharge rate of the emulsified asphalt.

[0040] In this embodiment, by setting up a lifting component 4, the scraper component 5 is located inside the material cylinder 1 and connected to the lifting component 4. During the descent of the lifting component 4, the scraper component 5 can drive the scraper component 5 to descend, and the scraper component 5 is in contact with the inner wall of the material cylinder 1. This allows the scraper component 5 to squeeze the emulsified asphalt during the descent, which accelerates the outflow of the emulsified asphalt in the material cylinder 1, improves the discharge speed of the emulsified asphalt, thereby improving the overall asphalt addition efficiency and reducing construction time. At the same time, the scraper component 5 can also scrape off the emulsified asphalt on the side wall of the material cylinder 1 during the descent, preventing the emulsified asphalt from depositing in the material cylinder 1, avoiding the pipe blockage problem caused by the deposit, and improving the reliability and service life of the equipment.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the lifting assembly 4 includes a screw 4-1, a nut 4-2, and a turntable 4-3. The screw 4-1 and the nut 4-2 are threaded together. The screw 4-1 passes through the through hole 1-1, and the nut 4-2 is fixed on the material cylinder 1. The turntable 4-3 is fixed to the top of the screw 4-1. The scraping assembly 5 is installed at the bottom of the screw 4-1.

[0042] The lifting assembly 4 includes a nut 4-2 and a screw 4-1. During the spiral rotation of the screw 4-1 and the nut 4-2, the screw 4-1 can rise or fall along its length. The scraper assembly 5 is installed at the bottom of the screw 4-1, so that the screw 4-1 can drive the scraper assembly 5 to rise or fall along its length during movement. During the descent of the scraper assembly 5, it can squeeze the emulsified asphalt in the material cylinder 1. Since the scraper assembly 5 is in close contact with the inner wall of the material cylinder 1, it can scrape off the emulsified asphalt occupying the inner wall of the material cylinder 1 during the descent. The cooperation between the nut 4-2 and the screw 4-1 reduces the shaking and deviation of the screw 4-1 during movement, improves the stability and reliability of the equipment, reduces the occurrence of mechanical failures, extends the service life of the equipment, and improves the durability of the equipment.

[0043] like Figure 1 and Figure 2As shown, in this embodiment, the scraping assembly 5 includes a scraper 5-1, which is installed at the bottom of the screw 4-1. The screw 4-1 can drive the scraper 5-1 to rise and fall inside the material cylinder 1. The scraper 5-1 is in contact with the side wall of the material cylinder 1 so that the scraper 5-1 can squeeze the emulsified asphalt during the descent process and scrape off the emulsified asphalt from the side wall of the material cylinder 1.

[0044] The scraper assembly 5 includes a scraper disc 5-1, which is installed at the bottom of the screw 4-1. The screw 4-1 can drive the scraper disc 5-1 to rise and fall inside the material cylinder 1. During the descent of the scraper disc 5-1 inside the material cylinder 1, it can squeeze the emulsified asphalt inside the material cylinder 1, accelerate the flow speed of the emulsified asphalt, and reduce the construction time. Since the emulsified asphalt is highly viscous, some of the emulsified asphalt will stick to the inner wall of the material cylinder 1 during the flow. The scraper disc 5-1 is in contact with the side wall of the material cylinder 1. During the descent of the scraper disc 5-1 inside the material cylinder 1, it can scrape off the emulsified asphalt sticking to the inner wall of the material cylinder 1, thereby increasing the utilization rate of the emulsified asphalt.

[0045] like Figure 2 As shown, in this embodiment, a rotating shaft 6 is also included. The screw 4-1 is a hollow screw 4-1, and the rotating shaft 6 is inserted inside the screw 4-1. The scraping assembly 5 also includes a scraper 5-2, which is located below the scraper disc 5-1. The rotating shaft 6 passes through the scraper disc 5-1 and is connected to the scraper 5-2. The rotating shaft 6 is used to drive the scraper 5-2 to rotate, so as to scrape off the emulsified asphalt at the bottom of the material cylinder 1.

[0046] The scraper assembly 5 also includes a scraper 5-2, which is located below the scraper disc 5-1. The rotating shaft 6 passes through the scraper disc 5-1 and is connected to the scraper 5-2. During the rotation of the rotating shaft 6, the scraper 5-2 will rotate. At this time, the scraper 5-2 can scrape off the emulsified asphalt at the bottom of the material cylinder 1, the inner wall of the material cylinder 1, and the bottom of the scraper disc 5-1. At the same time, the scraper 5-2 can shake off the residual emulsified asphalt on the scraper 5-2 during the rotation, which increases the utilization rate of emulsified asphalt and reduces costs in this embodiment.

[0047] In this embodiment, the scraper 5-2 is preferably made of an elastic material, which improves the flexibility and durability of the scraper 5-2, reduces the wear caused by friction between the scraper 5-2 and other parts during rotation, and allows the scraper 5-2 to fit against the bottom of the material cylinder 1, the bottom of the scraper disc 5-1 and the side wall of the material cylinder 1 respectively, so that the scraper 5-2 can scrape off the residual emulsified asphalt in the material cylinder 1.

[0048] Preferably, in this embodiment, the number of scrapers 5-2 is two or more, with multiple scrapers 5-2 (in this invention, multiple scrapers are two or more) spaced apart on the rotating shaft 6 along its circumference. The design of multiple scrapers 5-2 allows for more comprehensive coverage of the inner wall and bottom of the material cylinder 1, ensuring that the emulsified asphalt is thoroughly scraped off, reducing residue and improving scraping efficiency. Furthermore, the design of multiple scrapers 5-2 increases scraping redundancy; even if individual scrapers 5-2 wear or are damaged, the others can continue to operate, reducing the risk of equipment downtime due to a single component failure and improving equipment reliability.

[0049] In other embodiments, a groove (not shown in the figure) is formed at the bottom of the material cylinder 1 along the radial direction of the material cylinder 1. The length of the groove is not less than the radius of the material cylinder 1, and it forms an inclined angle with the bottom of the material cylinder 1. The discharge port 3 is connected to the groove, and the scraper 5-2 can scrape the emulsified asphalt into the groove, and then flow out of the material cylinder 1 through the groove and the discharge port 3. By setting the groove, the scraper 5-2 can scrape the emulsified asphalt at the bottom of the material cylinder 1 into the groove during rotation, and the discharge port 3 is connected to the groove, so that the scraper 5-2 can scrape the emulsified asphalt into the groove, thereby improving the utilization rate of the emulsified asphalt.

[0050] like Figure 1 and Figure 2 As shown, in this embodiment, a drive motor 7 is also included. The drive motor 7 is connected to the rotating shaft 6 and is used to drive the rotating shaft 6 to rotate.

[0051] By setting up a drive motor 7, and driving the drive motor 7 to drive the rotating shaft 6 to rotate, the drive motor 7 drives the rotating shaft 6 to rotate, which in turn drives the scraper 5-2 to rotate. This provides stable and controllable power, ensuring that the rotation of the scraper 5-2 is more uniform and efficient, thereby improving scraping efficiency and reducing the residue of emulsified asphalt in the material cylinder 1. The drive motor 7 can control the rotation speed of the scraper 5-2, ensuring that the residual emulsified asphalt on the scraper 5-2 can be shaken off during the rotation process.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, a first bracket 8 is also included, and the drive motor 7 is mounted on the turntable 4-3 through the first bracket 8.

[0053] By setting the first bracket 8, the drive motor 7 can be stably installed on the turntable 4-3, preventing the drive motor 7 from shaking and becoming unstable during the rotation of the turntable 4-3, thus improving the stability of the device and the safety of operators during the process.

[0054] like Figure 2 As shown, in this embodiment, the lifting assembly 4 also includes a fixing sleeve 4-4, and the screw 4-1 is connected to the scraper 5-1 through the fixing sleeve 4-4.

[0055] The screw 4-1 can be connected to the scraper 5-1 through the fixed sleeve 4-4, so that the fixed sleeve 4-4 moves along the length of the screw 4-1 during the rotation of the screw 4-1, thereby driving the scraper 5-1 to move, which increases the connection stability between the scraper 5-1 and the screw 4-1.

[0056] like Figure 1 and Figure 2 As shown, in this embodiment, the lifting assembly 4 also includes a rotating handle 4-5, which is mounted on the turntable 4-3 along the circumferential direction of the turntable 4-3.

[0057] The design of the rotary handle 4-5 makes it easier for operators to rotate the moving rod and adjust the position of the screw 4-1, improving the convenience and efficiency of operation. The design of the rotary handle 4-5 simplifies the operation process, reduces equipment failures caused by improper operation, lowers equipment maintenance costs, and improves the economy of the equipment.

[0058] like Figure 1 and Figure 2 As shown, in this embodiment, a first valve 9 and a second valve 10 are also included. The first valve 9 is installed on the feed inlet 2 and is used to control the opening and closing of the feed inlet 2. The second valve 10 is installed on the discharge outlet 3 and is used to control the opening and closing of the discharge outlet 3.

[0059] A first valve 9 and a second valve 10 are installed at the discharge port 3 and the inlet port 2, respectively. By controlling the opening and closing of the first valve 9 and the second valve 10, the input and output of emulsified asphalt can be precisely controlled, avoiding leakage and waste of emulsified asphalt, reducing environmental pollution and safety hazards, and improving the efficiency and safety of the equipment.

[0060] In this preferred embodiment, the first valve 9 and the second valve 10 are electric or pneumatic valves, which can realize automated control, reduce manual intervention, and improve the convenience and accuracy of operation.

[0061] like Figure 1 and Figure 2 As shown, this embodiment also includes a second support 11, which is installed on the material cylinder 1 to support it. The second support 11 ensures that the material cylinder 1 remains stable during operation, reducing the leakage of emulsified asphalt or equipment damage caused by shaking or instability of the material cylinder 1, thus improving the stability and reliability of the material cylinder 1. The second support 11 also reduces safety accidents caused by instability of the material cylinder 1, improving its safety, especially ensuring the safety of operators and the material cylinder 1 during operation.

[0062] In summary, such as Figures 1 to 3As shown, the usage process of this embodiment is as follows: First, the lifting assembly 4 is raised to the top of the material cylinder 1, the second valve 10 is closed and the first valve 9 is opened, and emulsified asphalt is fed into the material cylinder 1 through the feed inlet 2. When the emulsified asphalt in the material cylinder 1 is full, the first valve 9 is closed and the second valve 10 is opened. The handle is turned to lower the lifting assembly 4. During the descent of the lifting assembly 4, the scraper assembly 5 can be driven to descend. During the descent of the scraper assembly 5, the scraper 5-1 can scrape off the emulsified asphalt on the side wall of the material cylinder 1 until the bottom of the scraper 5-2 abuts against the bottom of the material cylinder 1 and the top of the scraper 5-2 abuts against the scraper 5-1. The descent of the lifting assembly 4 is stopped, and the drive motor 7 is started. The drive motor 7 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the scraper 5-2 to rotate, scraping off the emulsified asphalt on the side wall of the material cylinder 1, the bottom of the material cylinder 1 and the bottom of the scraper 5-1. At the same time, the emulsified asphalt adhering to the scraper 5-2 can be removed from the scraper 5-2. The scraped emulsified asphalt flows out from the discharge port 3.

Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
