Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt transportation, and in particular relates to an asphalt injection head with a double-port angle structure. Background Art

[0002] Asphalt has the characteristic of condensing at low temperatures. When it is transported over long distances, it needs to be filled at high temperatures at the place of departure. After long-distance transportation, the temperature of the asphalt drops and solidifies into a semi-solid state. It needs to be heated at the destination to complete the oil unloading operation.

[0003] The asphalt heater currently used is to accelerate the circulation convection heating of asphalt. Through the asphalt circulation pump, the hot asphalt is sprayed and convectionally impacted on the asphalt with lower temperature to promote the accelerated melting of asphalt. The asphalt spraying pipe currently used is connected to the asphalt circulation pump and the asphalt spraying head respectively. The cross section of the asphalt spraying head is circular, and the asphalt sprayed from the asphalt spraying head is a wire bundle structure with a small impact area, and the melting efficiency of asphalt is not high. Utility Model Content

[0004] The utility model aims to provide a double-port asphalt spray head with an angle structure to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

[0006] A double-port asphalt injection head with an angled structure comprises an asphalt injection head body, one end of which is connected to an asphalt injection pipe, and the asphalt injection pipe is connected to a circulating asphalt pump through a pipeline; two injection ports are arranged on the asphalt injection head body, and the angle between the axial midlines of the two injection ports on the same plane is an acute angle.

[0007] Furthermore, the two injection ports are not located at the center of the asphalt injection head body.

[0008] Furthermore, the two injection ports are not located in the same plane perpendicular to the asphalt injection head body.

[0009] Furthermore, the two injection ports do not overlap in the up-and-down directions of the asphalt injection head body.

[0010] Furthermore, an axial groove is provided on the inner wall on the opposite side of the two injection ports.

[0011] Furthermore, the cross section of the injection port is a shape consisting of a semicircle and a rectangle, wherein the side opposite to the two injection ports is a semicircle, and the other side is a rectangle.

[0012] The beneficial effects of the utility model are:

[0013] The asphalt injection head of the present technical solution is designed with two asphalt injection ports combined together, and the two asphalt injection ports have a certain angle. During the asphalt injection process, the fluids of the two asphalt injection ports that are close to each other attract each other and converge toward the center, and the two sides gradually move away from each other, thereby forming a dispersion surface. The two asphalt injection ports are not in the same plane, so that under different shooting speeds, the angles of the injection planes caused are different, thereby increasing the impact range, so as to be used in some short-distance, large-area asphalt heating scenarios.

[0019] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0020] The asphalt injection head of the present technical solution is used as a partial structure of an asphalt unloading trestle, an asphalt unloading station or other similar devices involved in unloading asphalt from an asphalt tanker or asphalt container that has been transported over a long distance. The device used is an asphalt heating device. As for heating the asphalt tanker or asphalt container or similar device for transporting asphalt, the heating method is the conventional method currently used. The present technical solution does not involve improvements to the heating device, and those skilled in the art can use it according to the actual situation of the unloading site. For this reason, the asphalt heating device is not introduced or illustrated in the technical solution of this application.

[0021] The asphalt injection head is used when an asphalt heating device is used to heat asphalt that has solidified into a solid or semi-solid state, such as in an asphalt tank truck or an asphalt container. At this time, part of the asphalt in the asphalt tank truck or the asphalt container has melted into a liquid state. At this time, in order to increase the melting rate of the asphalt and reduce the total heating time, the device related to the asphalt injection head of the present application will be used. Of course, this device can also be used, and it will not result in the inability to melt the asphalt, but it will only increase the melting time of the asphalt. All of the devices currently used to accelerate the melting of asphalt generally use asphalt circulation pumps. Some of the asphalt circulation pumps can be immersed in the melted asphalt, while others are installed above the asphalt tanker or asphalt container and do not immerse in the asphalt. The inlet of the asphalt circulation pump is inserted into the melted asphalt within the range of the heating device through a pipeline. The pipeline used is a hose. The outlet of the asphalt circulation pump is connected to the high-temperature asphalt pipeline through the pipeline. The high-temperature asphalt pipeline is also a hose. The purpose of using the hose is to facilitate movement. The other end of the high-temperature asphalt pipeline is connected to the asphalt injection pipe. The conventional asphalt injection pipe can be tied to the heating frame on the outside of the heating device by a rope. The applicant's prior patent application also made improvements. Instead of using a rope bundling method, the asphalt injection pipe is combined with the heating frame, and a simple pull rod and other structures are used to support or retract the asphalt injection pipe to the side of the heating frame. The above-mentioned structures are not involved in the technical solution of the present application, but are used to illustrate the installation position and usage scenario of the asphalt injection head of the present application. Therefore, even if the above-mentioned devices are not described in this application, it cannot be said that the disclosure of the technical solution of the present application is insufficient.

[0022] The technical solution of the present application uses an asphalt circulation pump. In the technical solution of the present application, the asphalt circulation pump can be a submersible pump immersed in asphalt, or it can be an asphalt pump arranged outside the asphalt container. If the asphalt circulation pump is a submersible pump, the outlet of the asphalt circulation pump is connected to the asphalt injection pipe through a hose; if the asphalt circulation pump is arranged outside the asphalt container, the inlet of the asphalt circulation pump is connected through a pipeline, and the outlet of the asphalt circulation pump is connected to the asphalt injection pipe through a hose.

[0023] In this technical solution, the asphalt circulation pumps are conventional technologies, which can be obtained by those skilled in the art through commercial channels as needed. Therefore, this technical solution does not describe the structure of the circulating asphalt pump, and the inlet or inlet pipe of the asphalt circulation pump is arranged within the range of the heating cage. A heater is arranged in the heating cage, and when the asphalt container is heated, the heating cage and the heater are immersed in the asphalt container.

[0024] like Figures 1 to 3As shown, the present application provides a double-port asphalt injection head with an angled structure, including an asphalt injection head body 1, one end of the asphalt injection head body 1 is connected to an asphalt injection pipe, and the asphalt injection pipe is connected to a circulating asphalt pump through a pipeline; two injection ports 2 are arranged on the asphalt injection head body, and the angle between the axial center lines of the two injection ports 2 on the same plane is an acute angle, and the angle between the axial center lines of the two injection ports of the present application is less than 30 degrees.

[0025] In the technical solution of the present application, the two injection ports are not located at the center of the asphalt injection head body. The two injection ports are not located in the same plane perpendicular to the asphalt injection head body. That is, in the technical solution of the present application, whether in the horizontal plane or the vertical plane perpendicular to the asphalt injection head body, the two asphalt injection ports are not in the same plane.

[0026] The two injection ports 2 do not overlap in the vertical direction of the asphalt injection head body. An axial groove (not shown in the figure) is provided on the inner wall on the opposite side of the two injection ports. In the technical solution of the present application, the number of the axial grooves can be more than two, so that the flow rate of the asphalt through the axial groove is faster. When the flow rates of the asphalt on the side close to the two relatively close asphalt injection ports are partially superimposed, the flow rate of the entire injection surface of the asphalt injection head is ensured to be relatively stable.

[0027] The cross section of the injection port is a shape composed of a semicircle and a rectangle, wherein the side opposite to the two injection ports is a semicircle 21 and the other side is a rectangle 22. This structure forms a larger injection surface area.

[0028] The asphalt spray head with two nozzles combined structure produces a spray surface during the spraying process, thereby increasing the impact range and being used in some short-distance and large-area asphalt heating scenarios.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
