[0002] Fluid is a kind of matter that can flow, it is a kind of object that will continuously deform under the action of any small shear force. Fluid is the general term of liquid and gas. It has easy flowability, compressibility and viscosity. The fluid composed of a large number of molecules that are constantly in thermal motion and have no fixed equilibrium position has certain compressibility, the compressibility of liquid is very small, and the compressibility of gas is larger. When the shape of the fluid changes, there is also a certain movement resistance between the layers of the fluid. The concentrated solution and suspension of high molecular polymer, petroleum, mud, coal water slurry, ceramic slurry, paper pulp and paint all belong to fluid. With the continuous expansion of industrial production scale, fluid conveying pipeline is needed to participate in the transportation between various fluids to improve the production and processing efficiency between fluids.

[0003] At present, a part of fluid conveying pipeline will be directly exposed to outdoor environment after being laid. If the fluid conveying pipeline is prone to freeze-up when the outdoor temperature is low in winter, the normal conveying effect of the subsequent fluid will be affected once freeze-up occurs. The most common way at present is to wrap flexible thermal insulation material outside the fluid conveying pipeline, and then wrap and bond with adhesive tape for several turns to make the thermal insulation material firmly adhere to the outside of the fluid conveying pipeline. This installation process is not convenient and time-consuming, and it is not convenient for subsequent maintenance. UTILITY MODEL CONTENT

[0034] The U-shaped block 11 is symmetrically arranged on the fluid conveying pipeline body 1;

[0035] The anti-freezing shell 12 is movably arranged on the outer side of the fluid conveying pipeline body 1 and is attached to the surface of the fluid conveying pipeline body 1, the anti-freezing shell 12 comprises a first shell 121 and a second shell 122 magnetically connected with the first shell 121 (the anti-freezing shell 12 is prepared from polyurethane heat preservation material);

[0036] The limiting rollers 128 are arranged on the first shell 121 and the second shell 122 respectively, and are in one-to-one correspondence with the U-shaped blocks 11 and are inserted into the U-shaped blocks 11.

[0037] The heat preservation pieces 126 are arranged on the inner walls of the first shell 121 and the second shell 122 at intervals in a circle (specifically, the heat preservation pieces 126 are heat preservation plates, and the inner sides of the heat preservation pieces 126 are provided with anti-skid pads, which are not shown in the figure).

[0038] The fixing grooves 127 are arranged on the inner walls of the first shell 121 and the second shell 122 at intervals in a circle and are distributed alternately with the heat preservation pieces 126, and the fixing grooves 127 are provided with electric heat tracing bands (the electric heat tracing bands are not shown in the figure and are arranged in the fixing grooves 127 by using heat-resistant adhesive tapes, so that the arrangement directions of the electric heat tracing bands are limited by the fixing grooves 127).

[0039] The handle 14 is symmetrically arranged on the first shell 121 and the second shell 122.

[0040] Further refinement of the embodiment scheme of the utility model is shown in Figs. Fig. 2 and Fig. 3 The first shell 121 is provided with a mounting groove 123, the mounting groove 123 is provided with a magnet 124, the second shell 122 is provided with a corresponding stainless steel block 125 which is matched in size with the mounting groove 123, and the stainless steel block 125 is matched with the magnet 124.

[0041] Further refinement of the embodiment scheme of the utility model is shown in Fig. Figs. 1-3 The first shell 121 and the second shell 122 are symmetrically provided with a receiving groove 13, and the receiving groove 13 is provided with the handle 14.

[0042] The working process of the utility model is as follows:

[0043] First, the first shell 121 and the second shell 122 are respectively close to the surface of the fluid conveying pipeline body 1 from both sides, and the design of the limiting roller 128 and the U-shaped table can avoid the instability of the anti-freezing shell 12 rotating around the fluid conveying pipeline body 1 after the butt joint of the first shell 121 and the second shell 122 is completed. At the same time, the stainless steel block 125 is aligned with the installation slot 123, and when the stainless steel block 125 enters the installation slot 123, it will be in contact with the magnet 124. After the two are in contact, the adsorption and fixation between the first shell 121 and the second shell 122 can be completed. The adsorption force of the magnet 124 is preselected, and when maintenance is needed later, the handle 14 is pulled outward from both sides to realize the separation between the anti-freezing shell 12 and the fluid conveying pipeline body 1. The anti-freezing shell 12 made of polyurethane thermal insulation material can effectively reduce the probability of freezing of the fluid conveying pipeline in winter. On this basis, the fluid conveying pipeline body 1 is warmed by the electric heating tape (the electric heating tape is laid in the fixed slot and is attached to the surface of the fluid conveying pipeline body 1 for subsequent disassembly and replacement), thereby further reducing the probability of freezing of the fluid conveying pipeline in winter, and the anti-freezing performance of the fluid conveying pipeline body 1 is significantly improved.

[0044] Compared with the prior art, the device adopts a light and heat-insulating anti-freezing shell 12 to cover the outside of the fluid conveying pipeline, thereby effectively preventing freezing and blocking in winter. At the same time, the installation and disassembly and maintenance of the anti-freezing shell 12 are convenient to operate, and one person can quickly complete the operation. In addition, the heat-insulating piece 126 and the electric heating tape are used to significantly improve the heat-insulating and anti-freezing effect, thereby making the fluid conveying pipeline more stable in winter.

[0045] In some embodiments, as shown in Fig. 3 In some embodiments, the first shell 121 and the second shell 122 are respectively provided with a fixed rod 15 symmetrical to the length thereof, and the fixed rod 15 is provided with a rubber layer, which is not labeled in the figure. This embodiment further improves the butt joint effect of the first shell 121 and the second shell 122 by using the fixed rod 15 and the rubber layer after the adsorption and butt joint of the first shell 121 and the second shell 122 are completed, and at the same time avoids the probability of damage caused by the violent collision between the first shell and the second shell during the butt joint process.

[0046] In some embodiments, a temperature sensor electrically connected with the electric heating tape is embedded in the anti-freezing shell; this embodiment is not shown in the figure. When the temperature sensor detects that the ambient temperature is lower than the pre-set value range, it immediately feeds back a signal to the electric heating tape to be powered on. The electric heating tape does not need to work all the time.
