Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, in particular to an asphalt heating and conveying device for cable aluminum sheathing. Background Art

[0002] Existing coating devices mainly include built-in roller type and built-in gear pump type. Heating is mainly performed by attaching a cast aluminum heating plate to the outside of the box. The built-in roller type and the built-in gear pump type have different defects. Using a cast aluminum heating plate for heating also has many shortcomings.

[0003] Built-in roller type: The roller is installed on the drive shaft and supported by the bearing seat. Since the power input relies on the drive shaft, the dynamic seal between the drive shaft and the box is affected by the repeated liquid-solid changes of high-viscosity asphalt. Complete sealing is difficult to achieve and leakage is very likely to occur. The escaping asphalt affects the environment and equipment.

[0004] Built-in gear pump: The gear pump is immersed in the asphalt, and the transmission shaft is vertically immersed in the gear pump. When the transmission structure rotates above the liquid surface, the asphalt will be thrown into the inside or even outside of the shell, causing safety impacts on the environment and equipment.

[0005] Cast aluminum heating plate: The temperature sensor often cannot be installed on the heating plate, the temperature control accuracy is poor, and it cannot accurately reflect the temperature of the heating plate in a timely manner, which is prone to accidents due to uncontrolled heating; often more heating plates also increase the maintenance workload.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 This is a schematic structural diagram of Example 1 of the present utility model; DETAILED DESCRIPTION

[0022] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] Combined with attachment Figure 1 A heating and conveying device for asphalt used for cable aluminum sheathing consists of an oil temperature machine 1, an insulation asphalt pump 2, an insulation conveying pipe 3, a heating furnace 4 and a smoke collection hood 5.

[0025] The oil temperature machine 1 is used to provide heat transfer oil and control the temperature of the heat transfer oil to keep the heat transfer oil at the working temperature. The insulated asphalt pump 2 is used to provide power for transporting asphalt. The delivery switch 3 is used to transport asphalt. The heating furnace 4 is used to heat the asphalt. The smoke hood 5 is used to prevent the gas emitted by the asphalt from spreading at will.

[0026] The oil temperature machine 1 is connected to the insulation asphalt pump 2, insulation delivery pipe 3, and heating furnace 4 respectively. The oil temperature machine 1 is connected to the insulation asphalt pump 2. The insulation delivery pipe 3 and the heating furnace 4 are connected to two pipelines for transporting hot oil and recovering cold oil.

[0027] Solid asphalt is put into the heating furnace 4, and the solid asphalt is heated by the heating furnace to become liquid asphalt. The user only needs to put the solid asphalt into the heating furnace 4, and the heating furnace 4 can heat the solid asphalt by itself.

[0028] Heating pipes are arranged around the inner side walls of the heating furnace 4. The heating pipes in the heating furnace 4 are arranged in an "S" shape, so that the heating pipes and the solid asphalt in the heating furnace 4 are fully heated, thereby melting the fixed asphalt.

[0029] The inlet and outlet ports of the heating pipe in the heating furnace 4 are connected to the oil temperature machine 1. The oil temperature machine 1 provides heat transfer oil. The heat transfer oil enters the inlet of the heating pipe through the hot oil conveying pipe. After flowing along the layout of the heating pipe, the heat transfer oil flows into the pipe for recovering cold oil from the outlet of the heating pipe, and then enters the oil temperature machine 1 again. The oil temperature machine 1 reheats the entering cold oil for recycling.

[0030] The melted liquid asphalt will flow into the insulation asphalt pump 2 , the inlet of the insulation asphalt pump 2 is connected to the asphalt outlet of the heating furnace 4 , and the outlet of the insulation asphalt pump 2 is connected to the inlet of the insulation delivery pipe 3 .

[0031] The thermal insulation asphalt pump 2 is connected to an external power device, which can be a motor or an engine. The power device is connected to the thermal insulation asphalt pump 2 through a transmission shaft to provide continuous power to the thermal insulation asphalt pump 2.

[0032] The interior of the insulated asphalt pump 2 also needs to be insulated to prevent the liquid asphalt entering the insulated asphalt pump 2 from solidifying after cooling. At the same time, the insulation function of the insulated asphalt pump 2 can ensure that the asphalt in the cavity is in a good liquid state when the asphalt pump is running, preventing the asphalt pump from being blocked when started. The insulation oil of the insulated asphalt pump 2 is also provided by the oil temperature machine 1. The heat transfer oil enters the inlet of the insulated asphalt pump 2 through the pipeline for conveying hot oil. The heat transfer oil wraps the insulated asphalt pump 2 and fully heats the insulated asphalt pump 2. Then, it flows from the outlet of the insulated asphalt pump 2 into the pipeline for recovering cold oil, and then enters the oil temperature machine 1 again. The oil temperature machine 1 reheats the entering cold oil for recycling.

[0033] The insulated asphalt pump 2 transfers the liquid asphalt into the insulated conveying pipe 3 through the power provided by the power equipment. At the same time, the insulated asphalt pump 2 continues to provide power to ensure that the liquid asphalt can complete the movement requirement from the inlet of the insulated conveying pipe 3 to the outlet of the insulated conveying pipe 3.

[0034] The outside of the insulated delivery pipe 3 is wrapped by an insulated pipe, and insulating oil flows in the insulated pipe to prevent asphalt from solidifying in the pipe and clogging the delivery pipe. The insulating oil of the insulated delivery pipe 3 is also provided by the oil temperature machine 1. The heat transfer oil enters the inlet of the insulated delivery pipe 3 through the pipe for transporting hot oil. The heat transfer oil wraps the insulated delivery pipe 3 and fully heats the insulated delivery pipe 3, then flows from the outlet of the insulated delivery pipe 3 into the pipe for recovering cold oil, and then enters the oil temperature machine 1 again. The oil temperature machine 1 reheats the entering cold oil for recycling.

[0035] The outlet of the heat-insulating delivery pipe 3 is a flat and long trumpet-shaped outlet, which can discharge the liquid asphalt more evenly.

[0036] A smoke hood 5 is provided on the top of the heating furnace 4. The smoke hood 5 can not only collect the waste removed from the asphalt and discharge it uniformly, but also the cable 6 that needs to be covered with asphalt passes through the smoke hood 5, and the insulated conveying pipe 3 extends into the smoke hood 5, and the trumpet-shaped outlet at the outlet of the insulated conveying pipe 3 is located directly above the cable.

[0037] The thermal insulation asphalt pump 2 transports the liquid asphalt into the thermal insulation delivery pipe 3, and the liquid asphalt is discharged from the trumpet-shaped outlet of the thermal insulation delivery pipe 3. The liquid asphalt drips onto the cable, forming a protective shell on the cable.

[0038] The oil temperature controller 1 directly sets the temperature of the thermal oil. The hot oil flows through the coils or circulation channels surrounding the inner wall of the heating furnace 4, heating the solid asphalt inside the furnace 4 until it liquefies and reaches the required process temperature. This allows for high-precision temperature control, allowing for easy adjustment based on asphalt adhesion.

[0039] During the entire coating process, there is no transmission mechanism within the furnace, preventing asphalt from being thrown out. Indirect heating with an oil temperature controller eliminates the poor temperature control accuracy of the heating plate and the associated heavy maintenance. A temperature display is installed within the furnace, but it is not involved in the control process. The oil temperature controller's setpoint is determined by the temperature of the asphalt within the furnace.

[0040] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
