Description

Technical Field

[0001] The utility model generally relates to the technical field of asphalt processing, and particularly relates to an asphalt warm mixing transmission device in alpine and high altitude regions. Background Art

[0002] Mixing foamed asphalt with aggregates is an implementation method of warm mix asphalt. When warm mix asphalt is processed, aggregates and foamed asphalt need to be added into the mixing cavity and stirred by a stirring shaft. The stirring shaft is generally driven by a motor, and a speed reducer is arranged between the motor and the stirring shaft as a transmission device. A reduction gear set and gear oil for lubrication are arranged inside the speed reducer. In alpine and high altitude regions, due to the low temperature, the viscosity of the gear oil increases when it gets cold. Although gear oil with low-temperature resistance is added during use, the effect is limited. The high viscosity of the gear oil will cause great resistance during cold start, resulting in slow motor speed increase, increased wear of the gears, and reduced service life. Summary of the Invention

[0003] In view of the above problems, the present application provides an asphalt warm mixing transmission device in alpine and high altitude regions to solve the technical problems proposed by the prior art.

[0006] A heat conduction flow channel arranged on the speed reducer housing and thermally coupled to the speed reducer, one end of the heat conduction flow channel is communicated with the transfer pipe, and the other end is communicated with the foaming pipe;

[0007] A heat insulation layer arranged on the outer side wall of the speed reducer housing.

[0008] Specifically, since the formation method of foamed asphalt is to supply high-temperature asphalt to the foaming pipe and simultaneously supply high-temperature water into the foaming pipe. The water and high-temperature asphalt are mixed in the foaming pipe, and the water forms steam, forming steam bubbles in the asphalt, thereby achieving the foaming effect. By setting the transfer pipe to communicate with an asphalt tank for supplying high-temperature asphalt or a water supply tank for supplying high-temperature water, when forming foamed asphalt, the high-temperature fluid flows through the heat conduction flow channel, thereby transferring part of the heat to the speed reducer housing, thereby heating the inside of the housing to ensure the fluidity of the internal gear oil. And by arranging a heat insulation layer on the speed reducer housing, heat dissipation is reduced, achieving a better heat preservation effect.

[0009] Further, the speed reducer housing includes a box cover, and heat conduction fins extending into the interior of the speed reducer housing are arranged on the box cover, and the heat conduction flow channel is arranged on the box cover.

[0011] Furthermore, a heating wire is arranged on the speed reducer housing, and the heating wire is connected to a power supply a.

[0012] Specifically, by arranging the heating wire and the power supply, before the warm mixing operation starts, the power supply supplies power to the heating wire first, so that the heating wire generates heat to heat the speed reducer housing to achieve the preheating effect. After the internal gear oil is heated and the viscosity becomes lower, the mixing operation starts. When the high-temperature asphalt or high-temperature water passes through the heat-conducting runner during the mixing operation, the heat of the high-temperature fluid can be used to heat the speed reducer housing. At this time, the power supply and the heating wire are controlled to be powered off. Through this setting method, preheating can be carried out to ensure that the gear oil has a suitable temperature and fluidity when the mixing device is initially started.

[0013] Furthermore, a control switch is arranged between the power supply and the heating wire, and the control switch is used to switch from the closed state to the open state when there is a flowing medium flowing in the transfer pipe.

[0014] Specifically, by arranging the control switch, it can be switched from the closed state to the open state when there is a fluid passing through the conveying pipe, so as to achieve the purpose of automatic power-off.

[0015] Furthermore, a plug-in hole is vertically arranged on the side wall of the transfer pipe perpendicular to the axis. The control switch includes a rotating rod rotatably arranged in the plug-in hole. A paddle is arranged at one end of the rotating rod extending into the transfer pipe. A torsion spring is arranged between the rotating rod and the transfer pipe. A conductive plate is arranged at the other end of the rotating rod. Two conductive columns are arranged at intervals around the rotating rod.

[0016] Furthermore, at least one limiting rod is also arranged around the rotating rod. Under the elastic force of the torsion spring, the conductive plate can abut against the limiting rod. When the conductive plate abuts against the limiting rod, the plate surface of the paddle is perpendicular to the axis of the transfer pipe.

[0017] Furthermore, the control switch includes a housing detachably and fixedly connected to the transfer pipe, and the conductive columns and the limiting rods are both arranged at the bottom of the housing.

[0026] The following further describes the present application in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the convenience of description, only parts related to the utility model are shown in the drawings.

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0028] The present utility model provides an asphalt warm mixing transmission device for alpine and high altitude regions. As a specific embodiment, referring to Figures 1-4 , it includes a reducer box body 1, and further includes:

[0029] The delivery pipe is used to supply fluid to the foaming pipe 3;

[0030] A heat conduction channel 11 is disposed on the reducer housing 1 and is thermally coupled to the reducer housing 1. One end of the heat conduction channel 11 is connected to the transmission pipe 2, and the other end is connected to the foaming pipe 3.

[0031] The heat insulation layer is arranged on the outer side wall of the reducer housing.

[0032] Specifically, it should be noted that reference Figure 1 The stirring system of warm mix asphalt includes a stirring chamber, a stirring shaft 7 is arranged in the stirring chamber, the stirring shaft is driven by a motor 71, and the motor drives the stirring shaft after being decelerated by a transmission device reducer. A foaming tube 3 is arranged above the stirring chamber. The foaming tube is formed by supplying high-temperature asphalt to the foaming tube and simultaneously supplying high-temperature water into the foaming tube. The water and the high-temperature asphalt are mixed in the foaming tube, the water forms steam, and steam bubbles are formed in the asphalt, thereby achieving a foaming effect. Figure 1 Exemplarily, 8 is a storage tank for high-temperature asphalt or a storage tank for high-temperature water, which is connected to an asphalt tank for supplying high-temperature asphalt or a water supply tank for supplying high-temperature water by setting a transmission pipe 2. When the foamed asphalt is formed, the high-temperature fluid flows through the heat conduction channel, thereby transferring part of the heat to the reducer housing, thereby heating the inside of the housing to ensure the fluidity of the internal gear oil, and by setting a heat insulation layer 2 on the reducer housing, the heat loss is reduced to achieve a better thermal insulation effect.

[0033] Further, as a specific implementation method, refer to Figure 2 The reducer housing 1 includes a housing cover 10 , on which heat-conducting fins 101 extending toward the interior of the reducer housing 1 are disposed, and the heat-conducting channel 11 is disposed on the housing cover 10 .

[0034] Specifically, the box cover 10 and the main body of the reducer box are detachably connected. By arranging the heat conduction channel 11 on the box cover, it is convenient for integral casting and production. By arranging the heat conduction fins 101, it is more conducive to temperature transfer.

[0035] Further, as a preferred embodiment, refer to Figure 2 A heating wire 4 is provided on the reducer housing 1, and the heating wire 4 is connected to a power supply 5a.

[0036] Specifically, by setting the heating wire 4 and the power supply 5a, before the warm mixing operation starts, the power supply 5 supplies power to the heating wire first, causing the heating wire to generate heat and heat the reducer housing to achieve the preheating effect. After the internal gear oil is heated and its viscosity becomes lower, the mixing operation starts. At this time, when the high-temperature asphalt or high-temperature water passes through the heat conduction channel 11, the temperature of the high-temperature fluid can be used to heat the reducer housing. At this time, the power supply 5a and the heating wire are controlled to cut off the power. Through this setting method, preheating can be carried out to ensure that the gear oil has a suitable temperature and fluidity when the mixing device is initially started.

[0037] Further, as a specific implementation manner, a control switch 5 is provided between the power supply 5a and the heating wire 4, and the control switch 5 is used to switch from the closed state to the open state when there is a flowing medium flowing in the transfer pipe 2.

[0038] Specifically, referring to Figure 2 , a control switch 5 and a manual switch 5b are provided between the power supply 5a and the heating wire. By setting the control switch 5, the control switch can switch from the closed state to the open state when there is a fluid passing through the conveying pipe, so as to achieve the purpose of automatic power-off.

[0039] Further, as a specific implementation manner, the specific structure of the control switch 5 is as follows: a plug hole 21 is provided on the side wall of the transfer pipe 2 perpendicular to the axis. The control switch 5 includes a rotating rod 51 rotatably arranged in the plug hole. One end of the rotating rod 51 extending into the transfer pipe 2 is provided with a paddle 52. A torsion spring (not shown in the figure) is provided between the rotating rod 51 and the transfer pipe. The other end of the rotating rod 51 is provided with a conductive plate 53, and two conductive columns 54 are arranged at intervals around the rotating rod 51.

[0040] Further, under the elastic force of the torsion spring, the conductive plate 53 can abut against the two conductive columns 54. When the conductive plate 53 abuts against the two conductive columns 54, the plate surface of the paddle is perpendicular to the axis of the transfer pipe 2.

[0041] Further, the control switch 5 includes a housing 56 detachably and fixedly connected to the transfer pipe, and the conductive column and the limiting rod are both arranged at the bottom of the housing 56.

[0042] Specifically, referring to Figure 3 、 Figure 4 , the torsion spring (not shown in the figure) can provide the rotating rod 51 with a direction along Figure 4The elastic force that rotates in the direction indicated by the arrow. In the initial state, when there is no fluid flowing inside the conveying pipe 2, under the elastic force of the torsion spring, the conductive plate 53 is connected to the two conductive posts 54 and is in a closed state. At this time, the paddle plate 51 is in a state perpendicular to the axis of the conveying pipe. When there is a flowing medium flowing inside the conveying pipe 2, the flowing medium pushes the paddle plate 51, causing the rotating rod 51 to rotate, thereby separating the conductive plate from the two conductive posts.

[0043] Specifically, referring to Figure 2 , as a specific implementation manner, in the initial state, the control switch 51 is in a closed state. At this time, the on / off of the circuit is controlled by the manual switch 5b. Before the work starts, the manual switch is controlled to be closed, then the circuit is connected, the heating wire generates heat, and after heating for 1 - 3 minutes, the production of warm mix asphalt starts, and high-temperature asphalt and high-temperature water are supplied. At this time, the flowing medium flows through the flow pipe 2, pushes the paddle plate to drive the rotating rod to rotate, thereby driving the conductive plate to separate from the two conductive posts 54, so that the control switch 51 is turned off, cutting off the power supply to the heating wire, achieving the purpose of automatic power-off. After the production of warm mix asphalt is completed, just turn off the manual switch.

[0044] Furthermore, as a specific implementation manner, a through hole 22 is provided on one side side wall of the conveying pipe 2, and a connecting plate 23 is provided at the through hole, and the insertion hole 21 is provided on the connecting plate 23.

[0045] Specifically, by providing the connecting plate 23 and the insertion hole 21, the insertion hole facilitates the passage of the paddle plate, thereby facilitating the installation of the control switch 5.
