Description

Technical Field

[0001] This utility model relates to the field of asphalt processing technology, and more specifically, to a feeding machine for asphalt processing. 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, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material. Asphalt has the following main characteristics: Viscosity: The viscosity of asphalt, also known as stickiness or viscosity, reflects the property of the asphalt material that hinders its relative flow, and reflects its hardness and consistency. Plasticity: Plasticity refers to the property of asphalt to deform under external force without breaking, and to retain its deformed shape after the external force is removed. Temperature sensitivity: Temperature sensitivity refers to the property of asphalt's viscosity and plasticity changing with temperature. High temperature sensitivity: The same asphalt will exhibit different forms such as liquid, solid, and semi-solid at different temperatures. Prone to aging: Because the components of asphalt are not stable compounds, they are affected by the external environment, causing the different parts of the asphalt to transfer, eventually leading to asphalt aging. High wax content: This is a major characteristic of domestically produced asphalt. High wax content affects the temperature stability and anti-skid properties of asphalt. Therefore, asphalt with high wax content is not suitable for road construction.

[0003] Natural asphalt cannot be used normally. Generally, different amounts of stabilizers are added depending on its intended use before it is used. Since asphalt is mostly semi-solid or liquid at room temperature, and even when it is liquid, its viscosity is very high. In this case, if stabilizers are added, the asphalt and stabilizers cannot be fully mixed, and the asphalt raw materials may even be wasted. Therefore, based on the temperature sensitivity of asphalt, we provide a feeding machine that can fully mix asphalt and stabilizers, namely, a feeding machine for asphalt processing. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding machine for asphalt processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a feeding machine for asphalt processing, including a shell, a heating plate fixedly connected to the inner wall of the shell, the heating plate having an "inclined" structure and being hollow inside, a plurality of heating resistance wires fixedly connected inside the heating plate, a support plate fixedly connected to the bottom of the heating plate, the other end of the support plate being fixedly connected to the inner wall of the shell, a motor fixedly connected to the bottom end of the support plate, a circular plate fixedly connected to the top end of the motor, and a stirring blade clamped to the bottom of the circular plate.

[0006] As a further improvement to this technical solution, the front and rear sides of the outer shell are provided with sliding grooves corresponding to the inclination of the heating plate. A scraper is slidably connected in the sliding groove, and a pusher is fixedly connected to the front end of the scraper.

[0007] As a further improvement to this technical solution, a spring is fixedly connected to the bottom end of the push block, and a fixing plate is fixedly connected to the other end of the spring. The fixing plate is fixedly connected to the outer surface of the outer shell.

[0008] As a further improvement to this technical solution, a circular hole is provided on the left side of the outer shell, and a ventilation pipe is fixedly connected inside the circular hole, and an exhaust fan is fixedly connected inside the ventilation pipe.

[0009] As a further improvement to this technical solution, both the top of the circular plate and the stirring blade are provided with slots, and a card plate is slidably connected in the slots, the size of which corresponds to the slot.

[0010] As a further improvement to this technical solution, a base is slidably connected to the bottom of the outer shell, and a pin is slidably connected to the base. Both the base and the outer shell are provided with grooves corresponding to the pins.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This asphalt processing feeder places the asphalt onto a heating plate during processing. Based on the temperature sensitivity of asphalt, the temperature on the heating plate increases, causing the viscosity of the asphalt to decrease. This makes the asphalt easier to mix and allows for more thorough mixing of the asphalt and stabilizer, thus better achieving the purpose of asphalt processing. Attached Figure Description

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] 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, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material. Asphalt has the following main characteristics: Viscosity: The viscosity of asphalt, also known as stickiness or viscosity, reflects the property of the asphalt material that hinders its relative flow, and reflects its hardness and consistency. Plasticity: Plasticity refers to the property of asphalt to deform under external force without breaking, and to retain its deformed shape after the external force is removed. Temperature sensitivity: Temperature sensitivity refers to the property of asphalt's viscosity and plasticity changing with temperature. High temperature sensitivity: The same asphalt will exhibit different forms such as liquid, solid, and semi-solid at different temperatures. Prone to aging: Because the components of asphalt are not stable compounds, they are affected by the external environment, causing the different parts of the asphalt to transfer, eventually leading to asphalt aging. High wax content: This is a major characteristic of domestically produced asphalt. High wax content affects the temperature stability and skid resistance of the asphalt; therefore, asphalt with high wax content is unsuitable for road construction. Please refer to [link / reference]. Figures 1-3 As shown, this embodiment provides a feeding machine for asphalt processing, including a housing 1. A heating plate 2 is fixedly connected to the inner wall of the housing 1. The heating plate 2 has an inclined structure and is hollow inside. Multiple heating resistance wires 21 are fixedly connected inside the heating plate 2. A support plate 22 is fixedly connected to the bottom of the heating plate 2. The other end of the support plate 22 is fixedly connected to the inner wall of the housing 1. A motor 23 is fixedly connected to the bottom of the support plate 22. A circular plate 24 is fixedly connected to the top of the motor 23. A stirring plate 26 is snapped into the bottom of the circular plate 24.

[0022] The improvement in this embodiment is as follows:

[0023] Since natural asphalt cannot be used normally, it is generally used with different amounts of stabilizers depending on its intended use. At room temperature, asphalt is mostly semi-solid or liquid, and even when liquid, its viscosity is very high. In this case, if stabilizers are added, the asphalt and stabilizers cannot be fully mixed, and the asphalt raw materials may even be wasted. Therefore, a heating plate 2 is fixedly connected to the inner wall of the outer shell 1. The heating plate 2 has an "inclined" structure and is hollow inside. Multiple heating resistance wires 21 are fixedly connected inside the heating plate 2. When the heating resistance wires 21 are energized, they heat up, raising the temperature of the heating plate 2. When asphalt is placed on the heating plate 2, the viscosity of the asphalt decreases as the temperature rises, making it easier to stir and mix with the stabilizer.

[0024] Considering that not all the asphalt on the heating plate 2 can fall into the base 3 for mixing, the front and rear sides of the outer shell 1 are provided with grooves 17 corresponding to the inclination of the heating plate 2. A scraper 11 is slidably connected in the groove 17, and a pusher 12 is fixedly connected to the front end of the scraper 11. By pushing the pusher 12 along the groove 17, the pusher 12 drives the scraper 11 to move along the inclined surface of the heating plate 2, and at the same time pushes the asphalt remaining on the heating plate 2 into the base 3.

[0025] In order to allow the scraper 11 to automatically return to its initial position after use, a spring 13 is fixedly connected to the bottom end of the push block 12, and a fixing plate 14 is fixedly connected to the other end of the spring 13. The fixing plate 14 is fixedly connected to the outer surface of the outer shell 1. After the scraper 11 is used, the spring 13 is compressed, and the scraper 11 returns to its initial position under the action of the elastic force of the spring 13.

[0026] Since asphalt itself has a pungent odor, and the odor becomes even more pungent after heating, in order to protect the user, a round hole is provided on the left side of the outer casing 1. A ventilation pipe 15 is fixedly connected to the round hole, and an exhaust fan 16 is fixedly connected to the ventilation pipe 15. The ventilation pipe 15 is connected to a rubber tube leading to the outside. The exhaust fan 16 draws the pungent odor generated by the asphalt to the outside, reducing the impact on the user.

[0027] To facilitate easier disassembly of the mixing plate 26, both the circular plate 24 and the top of the mixing plate 26 are provided with slots. A retaining plate 25 is slidably connected in the slots. The size of the retaining plate 25 corresponds to the slot. By pulling out the retaining plate 25 and moving the mixing plate 26 up and down, the mixing plate 26 can be removed. The asphalt remaining on the mixing plate 26 can be scraped into the base 3 for easy use next time.

[0028] To facilitate the removal of the processed asphalt, a base 3 is slidably connected to the bottom of the outer shell 1, and a pin 31 is slidably connected to the base 3. Both the base 3 and the outer shell 1 have grooves corresponding to the pin 31. By pulling out the pin 31 and lifting the outer shell 1 through the handle on top of the outer shell 1, the outer shell 1 can be separated from the base 3, thereby removing the processed asphalt.

[0029] In summary, the working principle of this solution is as follows:

[0030] When processing asphalt, the heating resistance wire 21 is first energized to preheat the heating plate 2. Then, the motor 23 is started, which drives the stirring blade 26 to rotate. At this time, the asphalt raw material is placed on the heating plate 2. Since the viscosity of asphalt decreases with increasing temperature, it slowly slides into the base 3 for stirring. By pushing the pusher block 12 along the slide groove 17, the pusher block 12 drives the scraper 11 to move along the inclined surface of the heating plate 2, while pushing the asphalt remaining on the heating plate 2 into the base 3. After use, the spring 13 is compressed. Under the action of the spring 13, the scraper 11 returns to the initial position, and the stabilizer is added from the inner wall of the left side of the outer shell 1 into the base 3. Under the rotation of the mixing plate 26, the asphalt raw material and the stabilizer are fully mixed. When the processing is completed, the pin 31 is pulled out, and the outer shell 1 is lifted by the handle on the top of the outer shell 1, so that the outer shell 1 is separated from the base 3. The clamping plate 25 is pulled out, and the mixing plate 26 is moved up and down to remove the mixing plate 26. The asphalt remaining on the mixing plate 26 is scraped into the base 3, so that all the asphalt is removed.
