Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pumping equipment, in particular to a high-viscosity asphalt pumping device. Background Art

[0002] Asphalt pumps are usually used for asphalt pumping. Most of the existing asphalt pumps are external gear pumps, which are widely used in various industries such as petrochemicals, metallurgy, machinery, electricity and highways. The structure of ordinary asphalt pumps is relatively complex. The temperature of asphalt is high when it is working. Once it cools down, it is difficult to clean and easily pollutes the internal structure of the asphalt pump. The disassembly, cleaning and maintenance of asphalt pumps takes a long time, and the cost of use and maintenance is high.

[0003] After searching, Chinese patent announcement number: CN214998059U discloses a high-viscosity asphalt pumping device, including: a cylinder body, an inlet check valve, an outlet check valve, a cover, a piston, a connecting seat, a driving flywheel, and a transmission connecting rod.

[0004] In the above technical solution, although the cylinder is heated and the asphalt is heated to prevent the asphalt from solidifying, the fact that the asphalt is difficult to solidify does not mean that it will not solidify.

Since the pumping device has a fixed structure and is often assembled with bolts and flanges, when the asphalt solidifies, it is necessary to remove the bolts several times before the outer shell can be opened and the solidified asphalt inside the cylinder can be processed. The operation is relatively cumbersome and inconvenient to use. Therefore, a high-viscosity asphalt pumping device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a high-viscosity asphalt pumping device, including a base 1, a shell 2 is fixedly connected to the top of the base 1, a pump core 23 is fixedly connected inside the shell 2, a feed pipe 4 and a discharge pipe 5 are fixedly connected to the outside of the shell 2, a power connection shaft 6 is arranged at one end of the pump core 23, and the pump core 23, the feed pipe 4, the power connection shaft 6 and the discharge pipe 5 cooperate to realize the transportation of asphalt. A shell cover 7 is arranged on the outside of the shell 2, and the shell cover 7 forms a complete shell after cooperating with the shell 2, which is used to protect the pump core 23. A convex ring 9 is fixedly connected to the outside of the shell 2, and a groove 10 is provided on the outside of the shell cover 7. The shapes of the convex ring 9 and the groove 10 are adapted to each other, so that they can be conveniently connected.

[0032] Reference Figure 3-Figure 4 , a protrusion 11 is fixedly connected to the outer side of the protruding ring 9, and a notch 12 and a slide groove 13 are provided on the outer wall of the groove 10. The protrusion 11 is adapted to the notch 12 and the slide groove 13. When the shell 2 and the shell cover 7 need to be connected, the protrusion 11 can be aligned with the notch 12, and the shell cover 7 can be inserted into the outer periphery of the protrusion 11 along the notch 12. Then, by rotating the shell cover 7, the protrusion 11 can be rotated along the direction of the slide groove 13, so that the alignment of the shell 2 and the shell cover 7 can be completed. A spring 14 is also fixedly connected to the middle of the shell 2, and a clamping rod 15 is fixedly connected to the other end of the spring 14. A through hole 19 is provided in the middle of the shell cover 7, and the clamping rod 15 is clamped with the through hole 19. After the alignment of the shell 2 and the shell cover 7 is completed, the clamping rod 15 will move toward the through hole 19 under the action of the spring 14, and after the clamping is completed with the through hole 19, the connection between the shell 2 and the shell cover 7 is realized. The end of the clamping rod 15 is fixedly connected with a positioning ring, and the positioning ring is slidably connected to the middle of the convex ring 9. The position of the clamping rod 15 can be limited by the positioning ring, thereby preventing the clamping rod 15 from extending excessively.

[0033] Reference Figure 3-Figure 4The shell cover 7 is slidably connected with a disassembly assembly, which includes a movable ring 16, which is slidably connected to the shell cover 7, and a top block 17 is fixedly connected to the outside of the movable ring 16. The top block 17 passes through the through hole 19 and contacts the clamping rod 15. When the shell cover 7 and the shell 2 need to be disassembled and separated, the movable ring 16 only needs to be pressed in the direction of the shell 2, so that the top block 17 can enter the middle of the through hole 19 to squeeze the clamping rod 15 out of the middle of the through hole 19. At this time, the shell cover 7 can be rotated along the slide groove 13 and the protrusion 11. When the protrusion 11 reaches the position of the notch 12, the separation of the shell cover 7 and the shell 2 can be completed. The operation is simple, thereby greatly improving the disassembly efficiency, thereby facilitating the cleaning of the solidified asphalt and facilitating the maintenance of the inside of the shell 2. A handle 18 is fixedly connected to the outside of the movable ring 16, and the handle 18 is slidably connected to the middle of the shell cover 7. The shell cover 7 can be operated more conveniently through the handle 18, so that the disassembly of the shell cover 7 is more convenient. The power connection shaft 6 passes through the middle of the housing cover 7 .

[0034] Reference Figure 2-Figure 3 A heating component is fixedly connected to the inside of the shell 2, and the heating component includes a heating rod 8. The heating rod 8 is fixedly connected to the inside of the shell 2. The inside of the shell 2 can be heated by the heating rod 8, so as to facilitate the transportation of asphalt.

[0035] Reference Figure 1-Figure 3 The top of the base 1 is fixedly connected with an insulated water tank 3, a water pump is fixedly connected inside the insulated water tank 3, the output end of the water pump is fixedly connected with a water inlet pipe 20, the shell 2 is fixedly connected with a heat collecting pipe 21, and the end of the heat collecting pipe 21 away from the water inlet pipe 20 is fixedly connected with a water outlet pipe 22, and the water outlet pipe 22 is connected with the insulated water tank 3. The water pump inside the insulated water tank 3 can transport the clean water stored inside the insulated water tank 3 from the water inlet pipe 20 to the heat collecting pipe 21, and then return to the inside of the insulated water tank 3 from the water outlet pipe 22 after passing through the heat collecting pipe 21, so that the heat inside the shell 2 can be adsorbed and recovered, thereby reducing energy consumption. The heat collecting pipe 21 bypasses the outer periphery of the heating rod 8, which can increase the contact area between the heat collecting pipe 21 and the heating rod 8, thereby improving the heat recovery efficiency. A cavity is formed between the pump core 23 and the shell 2, and the heat collecting pipe 21 is located in the cavity. The heating rod 8 will directly heat the cavity to facilitate the heating of the asphalt and the subsequent heat recovery operation.

[0036] Working principle: When in use, the cavity between the pump core 23 and the outer shell 2 is heated by the heating rod 8, and then the heat enters the pump core 23 through conduction. At this time, one end of the feed pipe 4 is connected to the asphalt, and the asphalt is transported under the action of the power connecting shaft 6. Then, when the asphalt enters the pump core 23, it can be heated and softened. The softened asphalt can be discharged from the discharge pipe 5, thus realizing the pumping operation of high-viscosity asphalt. When the asphalt solidifies inside the pump core 23, the handle 18 can be pressed to move the movable ring 16 toward the outer shell 2, so that the top block 17 passes through the middle of the through hole 19, thereby moving the top of the clamping rod 15 inside the through hole 19, and then the shell cover 7 is rotated by the handle 18 to rotate the shell cover 7 as a whole, so that the protrusion 11 reaches the notch 12 along the slide groove 13, and then the shell cover 7 and the outer shell 2 can be separated by taking the handle 18 and pulling the shell cover 7 outward. At this time, the internal situation of the outer shell 2 will be completely exposed, so as to facilitate the inspection and maintenance of the pump core 23 and the electrical components inside the outer shell 2. The operation is simple, the disassembly efficiency is greatly improved, and the use is more convenient.

[0037] Secondly, when the pumping device is used up, the water stored in the insulated water tank 3 can be transported from the water inlet pipe 20 to the inside of the heat collecting pipe 21 through the water pump inside the insulated water tank 3, and the heat collecting pipe 21 passes through the middle of the outer shell 2, so that the heat generated between the outer shell 2 and the pump core 23 can be adsorbed and carried, so that the heat can reach the inside of the insulated water tank 3 for storage, thereby realizing the recovery of waste heat to reduce energy consumption.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
