Problems solved by technology

[0002] Now the transportation of liquid paraffin is more difficult, because the paraffin will appear viscous when the temperature is not enough, which often leads to paraffin blockage, and the transportation pipeline cannot always be kept in a high temperature environment, so it is necessary to be able to maintain Paraffin is a liquid delivery line

Embodiment Construction

[0012] Such as figure 1 A temperature-controlled conveying pipe shown includes: an inner pipe 1 and an outer pipe 2; the outer pipe 2 is sleeved on the inner pipe 1, and the inner diameter of the outer pipe 2 is larger than the outer diameter of the inner pipe 1; the inner pipe 1 and liquid paraffin The output port A is connected; the outer pipe is connected with the heating output port B; the inner wall of the inner pipe is provided with a temperature sensing device 3; the heating output port B is the steam heating output port;

[0013] The present invention adopting the above technical solution realizes a ring tube with an annular cavity through the outer tube 2 sheathing the inner tube 1. Since the outer tube is connected to the heat supply outlet B, when the heat supply outlet B supplies heat , Will move along the annular cavity, so that a hot line is formed on the outer wall of the inner tube 1 that transports liquid paraffin, and the inner wall of the inner tube is provided...

Abstract

The invention discloses a controllable-temperature delivery pipe, which comprises an inner pipe and an outer pipe, wherein the outer pipe is sheathed on the inner pipe; the internal diameter of the outer pipe is more than the external diameter of the inner pipe; the inner pipe is connected with a liquid paraffin output hole A; the outer pipe is connected with a supplied heat output hole B; the inner wall of the inner pipe is provided with a temperature sensing device; and the supplied heat output hole B is a steam supplied heat output hole. According to the controllable-temperature delivery pipe adopting the technical scheme, an annular pipe with an annular cavity is realized in a mode that the inner pipe is sheathed by the outer pipe; because the outer pipe is connected with the supplied heat output hole B, the supplied heat output hole moves along the annular cavity when supplying heat; therefore, a heat pipeline is formed on the outer wall of the inner pipe for conveying the liquid paraffin; and the inner wall of the inner pipe is provided with the temperature sensing device for monitoring the temperature of the paraffin in the inner pipe all the time so as to enable operation personnel to conveniently increase or reduce heat supply.

Description

Technical field [0001] The invention relates to a conveying pipe, in particular to a temperature-controllable conveying pipe for conveying liquid paraffin. Background technique [0002] At present, the transportation of liquid paraffin is more difficult, because paraffin will become viscous when the temperature is not enough, which often causes paraffin to be blocked, and the delivery pipeline cannot always be maintained in a high temperature environment, so it needs a way to maintain Paraffin is a liquid conveying pipeline. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a temperature-controlled conveying pipe for conveying liquid paraffin. [0004] In order to achieve the above objectives, it is achieved through the following technical solutions: [0005] A temperature-controllable conveying pipe includes: an inner pipe and an outer pipe; the outer pipe is sleeved on the inner pipe, and the inner diameter of the outer pip...
