Description

Technical Field

[0001] This invention relates to an asphalt pump, and more specifically to an asphalt pump capable of rapid heating. Background Technology

[0002] An asphalt pump is a device that can transport or pump materials with high viscosity and easy solidification, such as asphalt. They have a wide range of applications in various fields, such as road construction, asphalt production, and chemical industries.

[0003] In industries such as road construction and petrochemicals, asphalt pumping is a crucial step. Because asphalt has a high viscosity at room temperature and may even solidify, it is usually necessary to heat it to reduce its viscosity, making it easier to pump.

[0004] However, in practice, asphalt is often heated to a certain temperature before it can be pumped using an asphalt pump. During this process, the asphalt may need to be transported through pipelines or other equipment. Due to heat dissipation during transport and the influence of ambient temperature, the asphalt may cool down before reaching the pump, leading to increased viscosity and making it more viscous, thus affecting its pumping efficiency.

[0005] Furthermore, if the temperature of the asphalt drops too much, it may cause the asphalt to solidify inside the asphalt pump, affecting the normal operation of the asphalt pump and even causing damage to the asphalt pump.

[0006] To address the temperature drop of asphalt during transportation due to heat dissipation and ambient temperature, asphalt pumps might be designed to heat the asphalt. However, such a design faces a technical challenge: how to quickly heat the incoming asphalt.

[0007] Especially when the asphalt transport volume is large, even if the asphalt pump has an internal heating system, it may be difficult to quickly and effectively heat the large amount of asphalt being transported. If heating is not timely, the temperature of the asphalt may still drop, leading to an increase in its viscosity and affecting the pumping efficiency.

[0008] In addition, the residence time of asphalt inside the pump is relatively short. If the asphalt is not heated enough, it may become viscous or even solidify inside the asphalt pump, which may affect the normal operation of the asphalt pump or even damage it.

[0009] Therefore, designing an asphalt pump that can quickly and effectively heat the asphalt to maintain its fluidity and improve its pumping efficiency when the asphalt transport volume is large is an urgent technical problem to be solved. Summary of the Invention

[0010] To address the aforementioned problems, this invention provides an asphalt pump capable of rapid heating. By designing a heating cylinder and a floating feed cylinder, this invention achieves rapid heating and pumping of asphalt, avoiding the situation where asphalt accumulates and is difficult to heat. At the same time, by utilizing rotary extrusion, it can divert heating and compensate for pumping efficiency when pumping efficiency decreases, effectively solving the shortcomings of the prior art.

[0011] This invention is achieved through the following technical solution: an asphalt pump capable of rapid heating, comprising:

[0012] The pump body has an inlet and an outlet. A pumping assembly is installed inside the pump body, and a drive assembly is installed outside the pump body. The drive assembly drives the pumping assembly.

[0013] A heating component is installed at the inlet of the pump body, and the asphalt is rapidly heated by the heating component and then conveyed into the pump body.

[0014] The heating assembly includes a heating cylinder, a floating feed cylinder, and a rotating support assembly. The heating cylinder has a heating chamber inside, and a conical heating surface is located on the bottom surface of the heating chamber. The heating assembly is embedded in the conical heating surface.

[0015] The rotating support assembly is floatingly supported on the top end face of the heating cylinder by an elastic telescopic assembly, and the floating feed cylinder is fixedly assembled in the rotating support assembly. The conical extrusion surface at the bottom of the floating feed cylinder extends into the heating chamber, and a gap heating chamber is formed between the conical extrusion surface and the conical heating surface.

[0016] A floating drive mechanism is provided at the connection between the drive component and the pump body. The floating drive mechanism is connected to the rotary support component. The rotational force generated by the drive component acts on the floating drive mechanism, thereby causing the rotary support component to float up and down. At this time, the floating feed cylinder performs floating extrusion heating action relative to the conical heating surface.

[0017] As a preferred technical solution, it also includes an overflow heating pipe, one input end of which is connected to the gap heating chamber, and one output end of which is connected to the discharge port. The asphalt located in the heating chamber is squeezed into the overflow heating pipe under high pressure, heated, and then discharged directly from the discharge port.

[0018] As a preferred technical solution, the rotating support device includes a bearing base and a support bearing. The support bearing is installed inside the bearing base, and the elastic telescopic component is disposed in the bearing base to support the bearing base. The floating feed cylinder is installed inside the support bearing near the feed end.

[0019] As a preferred technical solution, a sealing cover is provided at the top feed opening of the floating feed cylinder, and a feed conveying pipe is provided on the sealing cover. Asphalt is conveyed from the feed conveying pipe into the feed distribution chamber of the floating feed cylinder.

[0020] As a preferred technical solution, a conical guide column is provided on the bottom surface of the feeding distribution cavity, and multiple material distribution holes are arranged in a ring on the side of the bottom surface of the feeding distribution cavity away from the conical guide column. The asphalt entering the feeding distribution cavity is dispersed at the material distribution holes after being guided by the conical guide column and discharged into the heating cavity through the material distribution holes.

[0021] As a preferred technical solution, each of the elastic telescopic components includes a support cylinder, an air storage ring, a telescopic rod, and a lifting spring. A sealing piston is provided at the bottom of each telescopic rod, and an air inlet / outlet chamber is provided inside each support cylinder. The sealing piston at the bottom of the telescopic rod is sealed inside the air inlet / outlet chamber, and the other end of the telescopic rod extends to the outside of the support cylinder.

[0022] The top of the extension end of the telescopic rod is fixedly connected to the bottom of the rotating support device. The bottom of each support cylinder is fixedly welded to the air storage ring. The air storage ring has a first air storage chamber. The bottom of each support cylinder is connected to the first air storage chamber through an air guide hole.

[0023] The lifting spring is fitted on the outside of the telescopic rod. One end of the lifting spring contacts the upper end face of the support cylinder for support, and the other end of the lifting spring contacts the bottom of the rotating support device for support. When the support cylinder is filled with gas, the gas is used to lift the telescopic rod, thereby lifting the rotating support device and the floating feed cylinder installed in the rotating support device. The gas storage ring is connected to the floating drive mechanism through a connecting pipe.

[0024] As a preferred technical solution, the floating drive mechanism includes a cam and an elastic air storage component. Both the elastic air storage component and the cam are installed in a floating mounting cavity on one side of the pump body. One end of the cam is connected to a drive assembly and is driven to rotate by the drive assembly. The elastic air storage component is installed at any position on the inner wall of the floating mounting cavity.

[0025] The elastic gas storage component has a second gas storage chamber inside, and each of its two sides has an inclined guide surface. When the cam is driven to rotate by the drive assembly, it squeezes the elastic gas storage component. The elastic gas storage component is connected to the gas storage ring of the elastic telescopic assembly through a connecting pipe.

[0026] As a preferred technical solution, the drive assembly includes a drive motor and a reducer. The reducer is connected to the drive motor, and the output end of the reducer is connected to the pumping assembly inside the pump body. The cam is fixed on the output shaft of the reducer by a key. The drive assembly and the bottom of the pump body are both fixed on a working plate.

[0027] As a preferred technical solution, the input end of the overflow heating tube is provided with a sealing and pressure relief assembly, which includes a sealing ball, a sealing spring and a pressure relief pipe. The pressure relief pipe is embedded in the heating cylinder and has an opening on one side of the heating chamber to form a pressure relief feed port.

[0028] The pressure relief pipe has a pressure relief channel inside. The pressure relief channel is connected to the overflow heating pipe through a docking channel. One end of the sealing spring is installed in the pressure relief channel on the side away from the pressure relief inlet. The other end of the sealing spring pushes out the sealing ball. The inner diameter of the opening of the pressure relief inlet is smaller than the inner diameter of the pressure relief channel. The sealing ball pushed out by the sealing spring seals the pressure relief inlet.

[0029] One end of the overflow heating tube is installed at the output end of the docking channel, and an overflow heating component is arranged inside the overflow heating tube.

[0030] As a preferred technical solution, the inner wall of the heating chamber is provided with an inclined guide groove, and the outer side of the floating feed cylinder is provided with a guide rod at a position corresponding to the inclined guide groove. The guide rod is slidably installed in the inclined guide groove.

[0031] The bottom surface of the heating chamber is provided with a discharge extrusion port. The inlet of the pump body is connected to a feed bend, the outlet of the pump body is connected to a discharge pipe, the output end of the overflow heating pipe is connected to the discharge pipe, and the output end of the discharge extrusion port is connected to the feed bend.

[0032] The beneficial effects of the present invention are as follows: The present invention installs a heating cylinder and a floating feed cylinder at the input end of the asphalt pump. By using the rotational driving force of the drive component, the floating feed cylinder is driven to perform a floating extrusion action relative to the heating cylinder. In this way, a gap heating chamber is formed between the floating feed cylinder and the heating cylinder. The asphalt entering the heating chamber will be subjected to a conical extrusion under the floating force of the floating feed cylinder.

[0033] In addition, an inclined guide groove and guide rod are set between the floating feed cylinder and the heating cylinder, so that the floating feed cylinder can achieve floating rotation extrusion when it floats and rises relative to the heating cylinder. This allows the asphalt in the intermittent heating chamber to rotate and be extruded, so that the asphalt is flat and makes efficient contact with the heating components in the heating chamber, achieving rapid heating and preventing the situation where the asphalt cannot be fully heated due to a large accumulation of asphalt.

[0034] At the same time, by utilizing the above-mentioned rotary extrusion structure, when the asphalt pumping efficiency is reduced due to insufficient heating speed, the accumulated asphalt can be squeezed out into the overflow heating pipe by pressure. After being heated by the overflow heating pipe, it is directly diverted to the discharge port of the asphalt pump to distribute the pressure at the heating position. This satisfies the pumping volume requirements of the asphalt pump and, while meeting the heating requirements, also makes up for the problem of reduced pumping efficiency of the asphalt pump due to the viscosity of the asphalt.

[0035] Finally, the lifting and floating force of the floating feed cylinder of the present invention is realized based on the rotational force at the drive component. Combined with the floating drive mechanism, the structural design of the present invention is more reasonable. There is no need to add an additional drive component, which simplifies the structure and enables the present invention to achieve a rapid heating method of simultaneous extrusion and rotation, which greatly improves the conveying efficiency of the asphalt pump.

[0049] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0050] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0051] like Figure 1 and Figure 2 As shown, the present invention provides a rapid heating asphalt pump, including a pump body 2, the pump body 2 having an inlet 14 and an outlet 3, a pumping component is provided inside the pump body 2, and a drive component is provided outside the pump body 2, the drive component driving the pumping component.

[0052] It also includes a heating component, which is installed at the feed inlet 14 of the pump body 2. The heating component rapidly heats the asphalt and then transports it into the pump body 2. The heating component heats the input asphalt before pumping, reducing the impact of asphalt cooling and viscosity on pumping and meeting the pumping temperature value.

[0053] The heating assembly includes a heating cylinder 10, a floating feed cylinder 9, and a rotating support assembly. The heating cylinder 10 has a heating chamber, and the bottom surface of the heating chamber has a conical heating surface 21. The heating assembly is embedded in the conical heating surface 21. The heating assembly can be made by embedding multiple electric heating wires in the conical heating surface 21. The multiple electric heating wires heat the area, so that the entire conical heating surface 21 generates a high temperature. The electric heating wires can be controlled by an external heating controller to control the switch and the heating temperature value. Because of the use of the conical heating surface 21, the asphalt flowing down from the top will first contact the top of the conical heating surface 21, and then move towards the middle along the conical inclined surface of the conical heating surface 21. The entire process of moving towards the middle allows the asphalt to cover the conical heating surface 21, achieving the purpose of uniform contact heating.

[0054] The function of the rotating support assembly is to support the floating feed cylinder 9 and to support and rotate the floating feed cylinder 9. The rotating support assembly is located at the top of the heating cylinder 10, so the floating feed cylinder 9 is supported outside the heating cylinder 10. The bottom of the floating feed cylinder 9 extends into the heating cavity of the heating cylinder 10. The outer wall of the floating feed cylinder 9 can form a certain gap with the inner wall of the heating cavity. A sealing ring, such as a PTFE sealing ring, can be set on the inner wall of the top opening of the heating cavity to increase the sealing of the opening. The sealing ring can be set as multiple overlapping rings.

[0055] like Figure 9 As shown, the rotating support assembly is floatingly supported on the top end face of the heating cylinder 10 by the elastic telescopic assembly 25, and the floating feed cylinder 9 is fixedly assembled in the rotating support assembly. The conical extrusion surface at the bottom of the floating feed cylinder 9 extends into the heating chamber, and a gap heating chamber 23 is formed between the conical extrusion surface and the conical heating surface 21. Figure 3 As shown, the space of the interstitial heating chamber 23 is small, and the asphalt inside the interstitial cooling chamber can become very thin, thereby achieving full contact with the conical heating surface 21, increasing heating efficiency, and achieving the purpose of high-efficiency heating;

[0056] A floating drive mechanism is provided at the connection between the drive assembly and the pump body 2. The floating drive mechanism is connected to the rotary support assembly. The rotational force generated by the drive assembly acts on the floating drive mechanism, causing the rotary support assembly to float up and down. At this time, the floating feed cylinder 9 performs a floating extrusion heating action relative to the conical heating surface 21. When the drive assembly is working, that is, when the entire asphalt pump is working, the drive assembly drives the floating drive mechanism, thereby causing the floating feed cylinder 9 to float up and down. When the floating feed cylinder 9 floats up and down, since the position of the conical heating surface 21 remains unchanged, the floating feed cylinder 9 floats up and down. As the feed cylinder 9 floats up and down, the space of the entire gap heating chamber 23 is constantly changing, that is, the gap chamber switches back and forth between increasing and decreasing. When the floating feed cylinder 9 floats up and down, the bottom surface of the conical floating feed cylinder 9 is used to achieve the purpose of conical extrusion of asphalt, so that the asphalt located in the gap heating chamber 23 is flattened and spread in the gap heating chamber 23. At the same time, this extrusion force allows the asphalt to be heated and then squeezed into the feed inlet 14 with the next extrusion of the floating feed cylinder 9, thereby improving the conveying efficiency of the asphalt pump.

[0057] like Figure 2 and Figure 4 As shown, the present invention also includes an overflow heating pipe 5. One input end of the overflow heating pipe 5 is connected to the gap heating chamber 23, and the output end of the overflow heating pipe 5 is connected to the discharge port 3. The asphalt in the heating chamber is squeezed into the overflow heating pipe 5 under high pressure and then discharged directly from the discharge port 3. When the asphalt cannot be heated in time to reach the optimal conveying temperature, the fluidity of the asphalt will deteriorate, and the pumping efficiency of the asphalt pump will decrease. After the efficiency decreases, as the asphalt continues to accumulate, the amount of asphalt in the heating chamber increases. At this time, the asphalt in the floating feed cylinder 9 is still being continuously fed into the feed conveying pipe 8, so the weight of the entire floating feed cylinder 9 becomes heavier and heavier. As the weight continues to increase, the elastic telescopic component 25 at the bottom of the floating feed cylinder 9 will also be pressed down. At this time, the total mass of the entire floating feed cylinder 9 and the asphalt inside will act on the asphalt accumulated in the gap heating chamber 23. At this time, excess asphalt in the interstitial heating chamber 23 will be forced out into the overflow heating pipe 5. The overflow heating pipe 5 is closed when the heating efficiency in the interstitial heating chamber 23 can be guaranteed, so it does not work under normal conditions. Once the heating efficiency of the asphalt in the interstitial heating chamber 23 decreases, the pumping efficiency of the asphalt pump decreases, and the amount of asphalt entering and accumulating in the floating feed cylinder 9 increases. At this time, the weight of the floating feed cylinder 9 and the accumulated asphalt can be used to squeeze the excess asphalt in the interstitial heating chamber 23, so that it enters the overflow heating pipe 5 for emergency heating and discharge. In this way, the asphalt entering the overflow heating pipe 5 can be heated and transported separately. The heated asphalt is directly output from the discharge port 3 along with the asphalt pump. In this way, the asphalt pump, which originally had reduced pumping efficiency, can make up for the problem of insufficient asphalt pump delivery volume with the assistance of the overflow heating pipe 5.

[0058] In this embodiment, there can be multiple overflow heating tubes 5, but only one is shown in the figure. In actual use, multiple tubes can be set along the heating cylinder 10 to meet the needs of different situations.

[0059] like Figures 1-3 As shown, the rotating support device includes a bearing base 12 and a support bearing 11. The support bearing 11 is installed inside the bearing base 12. The elastic telescopic component 25 is disposed in the bearing base 12 and supports the bearing base 11. The floating feed cylinder 9 is installed inside the support bearing 11 near the feed end. The bearing base 12 is used to install the support bearing 11 and can also be used for contact support of the elastic telescopic component 25. The support bearing 11 is a ball bearing commonly used in the art. Therefore, the floating feed cylinder 9 installed inside the support bearing 11 can achieve the purpose of support and rotation.

[0060] Please continue reading. Figures 1-3 In the figure, a sealing cover is provided at the top feed opening of the floating feed cylinder 9. The sealing cover is provided with a feed conveying pipe 8. Asphalt is conveyed into the feed distribution chamber of the floating feed cylinder 9 through the feed conveying pipe 8. The sealing cover can be threadedly engaged with the floating feed cylinder 9. The feed conveying pipe 8 can be connected to an external asphalt tank. The asphalt tank is set at a high position, so that the preheated asphalt can be conveyed from top to bottom into the floating feed cylinder 9 through the feed conveying pipe 8.

[0061] like Figure 3 , Figure 4 and Figure 6 As shown, a conical guide column 24 is provided on the bottom surface of the feeding distribution chamber. Multiple distribution holes 19 are arranged in a ring on the side of the bottom surface of the feeding distribution chamber away from the conical guide column 24. The asphalt entering the feeding distribution chamber is dispersed at the distribution holes 19 after being guided by the conical guide column 24 and discharged into the heating chamber through the distribution holes 19. Due to the conical guide column 24, the asphalt entering the feeding distribution chamber through the feeding conveying pipe 8 can be distributed at the edge of the feeding distribution chamber. Since the distribution holes 19 are provided at the edge, the accumulated asphalt can be discharged downward from these distribution holes 19 into the heating chamber. The distribution holes 19 shown in the figure can form an angle of less than 90 degrees with the horizontal plane.

[0062] like Figure 7 , Figure 9 and Figure 10As shown, each of the elastic telescopic components 25 includes a support cylinder 252, an air storage ring 27, a telescopic rod 251, and a lifting spring 253. The bottom of each telescopic rod 251 is provided with a sealing piston, and each of the support cylinders 252 is provided with an air inlet and outlet chamber. The sealing piston at the bottom of the telescopic rod 251 is sealed in the air inlet and outlet chamber, and the other end of the telescopic rod 251 extends to the outside of the support cylinder 252.

[0063] The top of the extended end of the telescopic rod 251 is fixedly connected to the bottom of the rotating support device. The bottom of the support cylinder 252 is fixedly welded to the air storage ring 27. The air storage ring 27 has a first air storage chamber. The bottom of each support cylinder 252 is connected to the first air storage chamber through an air guide hole.

[0064] The lifting spring 253 is fitted onto the outside of the telescopic rod 251. One end of the lifting spring 253 contacts and supports the upper surface of the support cylinder 252, while the other end contacts and supports the bottom of the rotating support device. When gas is filled into the support cylinder 252, the gas lifts the telescopic rod 251, thereby lifting the rotating support device and the floating feed cylinder 9 installed in the rotating support device. The gas storage ring 27 is connected to the floating drive mechanism via the connecting pipe 15. When the drive assembly is working, i.e., when the drive shaft of the drive assembly rotates, the floating drive mechanism forces gas through the drive assembly into the gas storage ring 27. The gas storage ring 27 can be made of hard metal and has a sealed interior. In the first gas storage chamber, when the floating drive mechanism is squeezed, gas enters the gas storage ring 27 through the connecting pipe 15, increasing the gas volume in the gas storage ring 27. Excess gas enters the support cylinder 252 through the air guide hole. After the gas volume in the support cylinder 252 increases, it pushes up the telescopic rod 251. The telescopic rod 251 is pushed out into the support cylinder 252, causing the rotating support device to rise. When the drive component stops squeezing the floating drive mechanism, the gas in the support cylinder 252 returns to the gas storage ring 27, and the excess gas in the gas storage ring 27 returns to the floating drive mechanism. At this time, the entire rotating support device is lowered, that is, the floating feed cylinder 9 is lowered, thereby achieving the purpose of the floating feed cylinder 9 floating up and down.

[0065] Please see Figure 2 , Figure 2In the floating drive mechanism, there are a cam 16 and an elastic air storage component 18. Both the elastic air storage component 18 and the cam 16 are installed in the floating mounting cavity 17 on one side of the pump body 2. One end of the cam 16 is connected to the drive assembly and is driven to rotate by the drive assembly. The elastic air storage component 18 is installed at any position on the inner wall of the floating mounting cavity 17. In this embodiment, the elastic air storage component 18 is installed at the bottom of the floating mounting cavity 17. When the cam 16 rotates, the cam 16 contacts and squeezes the elastic air storage component 18, thereby causing the gas in the elastic air storage component 18 to enter and exit into the air storage ring 27. Therefore, as long as the cam 16 rotates continuously, it can intermittently contact the elastic air storage component 18, so that the floating feed cylinder 9 is in a floating lifting state.

[0066] The elastic gas storage component 18 has a second gas storage chamber inside. Each side of the elastic gas storage component 18 has an inclined guide surface, which allows the cam 16 to better contact and compress the elastic gas storage component 18 when it rotates. When the cam 16 is driven to rotate by the drive assembly, the cam 16 compresses the elastic gas storage component 18. The elastic gas storage component 18 is connected to the gas storage ring 27 of the elastic telescopic component 25 through the connecting pipe 15. The elastic gas storage component 18 can be made of elastic wear-resistant rubber material to store gas and recover its deformation when not compressed.

[0067] like Figure 1 and Figure 2 As shown, the drive assembly includes a drive motor 7 and a reducer 6. The reducer 6 is connected to the drive motor 7, and the output end of the reducer 6 is connected to the pumping assembly inside the pump body 2. The cam 16 is fixed to the output shaft of the reducer 6 by a key. The drive assembly and the bottom of the pump body 2 are both fixed to a working plate 1. The reducer 6 is used to reduce the rotation speed of the cam 16, so that the entire floating feed cylinder 9 floats up and down slowly. The drive assembly is a common technology in the field and will not be described in detail here.

[0068] like Figure 4 and Figure 5 As shown, the input end of the overflow heating tube 5 is provided with a sealing pressure relief assembly 22. The sealing pressure relief assembly 22 includes a sealing ball 225, a sealing spring 224 and a pressure relief pipe 223. The pressure relief pipe 223 is embedded in the heating cylinder 10. The pressure relief pipe 223 is located on one side of the heating chamber and opens to form a pressure relief feed port 22614.

[0069] The pressure relief pipe 223 has a pressure relief channel, which is connected to the overflow heating pipe 5 via a docking channel 222. One end of the sealing spring 224 is installed in the pressure relief channel on the side away from the pressure relief inlet 22614, and the other end of the sealing spring 224 pushes out the sealing ball 225. The inner diameter of the opening of the pressure relief inlet 22614 is smaller than the inner diameter of the pressure relief channel. The sealing ball 225 pushed out by the sealing spring 224 seals the pressure relief inlet 22614. Because the inner diameter of the opening of the pressure relief inlet 22614 is smaller than the inner diameter of the pressure relief channel, the seal is effective. Under the force of the sealing spring 224, the sealing ball 225 is pushed to the position of the pressure relief inlet 22614, thus sealing the pressure relief channel. Therefore, when the pressure in the intermittent heating chamber 23 is not high, that is, when the heating speed is sufficient to meet the pumping efficiency, this pressure relief channel will not be opened. When the pressure increases, the excess asphalt will push open the sealing ball 225, that is, the sealing ball 225 will retract, the sealing spring 224 will be compressed, the pressure relief channel will open, and the excess asphalt will enter the overflow heating pipe 5 through the pressure relief channel and the docking channel 222 for heating and discharge.

[0070] One end of the overflow heating tube 5 is installed at the output end of the docking channel 222. An overflow heating component 221 is arranged inside the overflow heating tube 5. In this embodiment, the overflow heating component 221 can also be made of multiple heating wires arranged inside the overflow heating tube 5 to heat the overflow heating tube 5. When the extruded asphalt passes through the overflow heating tube 5, the overflow heating component 221 can be used to heat the asphalt. An insulation layer can be wrapped around the outside of the overflow heating tube 5 to prevent heat loss. The overflow heating component 221 and the heating component arranged in the heating chamber can use the same temperature controller to control their switching and temperature, and are powered by an external power supply.

[0071] To enable the floating feed cylinder 9 to better compress the asphalt and disperse the asphalt lumps, in this embodiment, an inclined guide groove 28 is provided on the inner wall of the heating chamber, and a guide rod is provided on the outer side of the floating feed cylinder 9 at a position corresponding to the inclined guide groove 28. The guide rod is slidably installed in the inclined guide groove 28. When the floating feed cylinder 9 floats up and down, the guide rod and the inclined guide groove 28 prevent the floating feed cylinder 9 from floating vertically, but rather from floating and rising in a rotating manner. This allows the asphalt to be more evenly compressed and dispersed, making better contact with the heating surface and improving the heating efficiency of the asphalt.

[0072] A discharge outlet 26 is provided on the bottom surface of the heating chamber. A feed bend 13 is connected to the inlet 14 of the pump body 2, and a discharge pipe 4 is connected to the outlet 3 of the pump body 2. The output end of the overflow heating pipe 5 is connected to the discharge pipe 4. The output end of the discharge outlet 26 is connected to the feed bend 13. The feed bend 13 and the inlet 14 can be connected via a flange or a threaded connection. Figure 6As shown, the diameter of the discharge extrusion port 26 is not set too large. This way, when the floating feed cylinder 9 floats and rises, the asphalt can be squeezed and dispersed, and the asphalt can stay in the heating chamber for a longer time, so that the heating can be more thorough. After heating, the asphalt fluidity becomes better, and it can be squeezed out from the discharge extrusion port 26 into the feed bend 13 under the squeezing pressure of the floating feed cylinder 9. When the asphalt is not heated in time or the heating efficiency is not high, the asphalt pressure in the heating chamber can be increased. When squeezed again, the accumulated excess asphalt can be heated and discharged from the overflow heating pipe 5.
