Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of asphalt mixers, and particularly relates to an asphalt mixer that facilitates asphalt heating. Background Technology
[0002] After heating, asphalt needs to be uniformly stirred inside an asphalt mixer before adding the materials required for actual use. At this time, the temperature of the asphalt is prone to continuously decreasing, which will cause the asphalt to gradually solidify. Therefore, current asphalt mixers will heat the asphalt while it is being uniformly stirred.
[0003] Typically, the heating components of asphalt mixers are mostly located on the ring side of the mixing tank. The heat is too concentrated on the ring side of the asphalt mixer. Due to the special properties of asphalt, the heat transfer effect is poor. Although mixing can enhance the fluidity of the asphalt, the heat is still not easy to disperse to the central area, affecting the heat distribution effect during the asphalt mixing process. As a result, the final mixing effect is poor due to uneven heat distribution and poor asphalt fusion. Utility Model Content

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0029] This utility model embodiment provides an asphalt mixer that facilitates asphalt heating, such as... Figures 1-7 As shown, the asphalt mixer for facilitating asphalt heating includes:
[0030] The main cylinder 300 has an opening at its top end and a heating chamber assembly 200 inside. The heating chamber assembly 200 includes an equipment compartment 220 and heating chambers 210 distributed on the equipment compartment 220. The equipment compartment 220 includes a connecting hole 221 and a compartment body 222. Three sets of connecting holes 221 are arranged in a ring array on the compartment body 222. The connecting holes 221 are interconnected to form a heating chamber 210 with a clover-like structure. A heating layer is also arranged on the outer ring side of the heating chamber 210 to heat the inside of the heating chamber 210 using the heat generated by the heating layer.
[0031] The interior of the main cylinder 300 is divided into a processing area 310 and a collection area 320 by the heating chamber assembly 200. The processing area 310 and the collection area 320 can be connected through the connecting hole 221. After the asphalt solution is added, it will submerge the entire heating chamber assembly 200. The heating chamber assembly 200, together with the heating components provided on the outer wall of the main cylinder 300, is used to heat the asphalt solution as a whole. Here, the arrangement of the heating chamber assembly 200 and the heating components of the main cylinder 300 adopts the existing kettle heating method.
[0032] A mixing device 100 includes a cover 120 and three sets of mixing blades 130 disposed on the cover 120. The cover 120 covers the top of the main cylinder 300, and the sets of mixing blades 130 extend into different connecting holes 221 to mix the asphalt flowing in the processing area 310 and the heating chamber 210. Here, the length of the mixing blades 130 is slightly lower than the depth of the main cylinder 300, so that the mixing operation can be carried out inside the main cylinder 300, reducing the mixing dead corners.
[0033] It should be noted that the height of the heating chamber assembly 200 is only half the depth of the main cylinder 300, so as to avoid the heating chamber assembly 200 occupying too much space inside the main cylinder 300 and affecting the processing volume inside the equipment.
[0034] In this application, a specially constructed heating chamber 210 is arranged inside the main cylinder 300. The multi-curved surface structure of the heating chamber 210 increases the contact area with the asphalt solution and improves the heat transfer efficiency during the heating process. Furthermore, the annular array distribution of the cylinder structure allows the heat to be distributed more evenly in the asphalt solution, enabling the asphalt to complete the mixing and fusion under a stable temperature environment.
[0035] In a preferred embodiment of this invention, a heating layer 223 is provided on the circumferential side of the connecting hole 221, and a heating coil is arranged inside the heating layer 223. The heating layer 223 is arranged inside the equipment compartment 220, and the heating function of the heating layer 223 is mainly achieved by setting a curved space on the circumferential side of the connecting hole 221 and arranging a heating coil in the curved space.
[0036] In this embodiment, the heating layers on the different connecting holes 221 are not interconnected and can be set independently. During the processing, independent control can be achieved to balance the temperature of different areas and avoid the situation where the temperature difference between different areas cannot be adjusted. Temperature sensors are provided on the stirring paddles 130 that extend to different areas to facilitate monitoring the temperature difference between different areas. When a temperature difference occurs, the heating layers 223 in different areas can be controlled accordingly to perform heating control.
[0037] In a preferred embodiment of this invention, the main cylinder 300 is provided with a bottom support ring 230 to support the heating chamber assembly 200. The heating chamber assembly 200 is placed directly on the bottom support ring 230, which facilitates pulling the entire heating chamber assembly 200 out of the main cylinder 300 during equipment maintenance. The equipment compartment 220 is also provided with a wire harness conduit 240 for arranging wires. The wire harness conduit 240 introduces external wiring into the equipment compartment 220. Typically, the end of the wire harness conduit 240 extends above the asphalt filling level, mainly to protect the wiring introduced into the equipment compartment 220.
[0038] The main cylinder 300 is provided with a discharge port on one side of the collection area 320. The main function of the discharge port is to discharge the asphalt solution after the mixing is completed.
[0039] In a preferred embodiment of this invention, a drive motor 110 is provided on the outside of the cover 120, and a gear transmission structure is provided inside the cover 120. The motor shaft of the drive motor 110 extends into the inside of the cover 120 and is connected to the gear transmission structure. One end of the stirring paddle 130 extends into the inside of the cover 120 and is connected to the gear transmission structure. The three sets of stirring paddles 130 rotate synchronously under the transmission action of the gear transmission structure.
[0040] The gear transmission structure includes a driving gear 111 and three sets of driven gears 112. The driven gears 112 are meshed with the driving gear 111. The driving gear 111 is connected to the motor shaft of the drive motor 110. The driven gears 112 are connected to the rotation shaft of the stirring paddle 130.
[0041] In this embodiment, both the drive motor 110 and the stirring paddle 130 are existing technologies. The number of stirring paddles 130 and driven wheels 112 is adjusted and adapted according to the number of connecting holes 221. The dimensions between the driven wheels 112 can also be improved according to the stirring needs, allowing different stirring paddles 130 to achieve different stirring speeds, improving the internal mixing effect and avoiding poor uniformity when stirring at the same speed.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
