Description

Technical Field

[0001] The invention belongs to the technical field of hose design, and in particular relates to an integrated thermal insulation metal hose. Background Art

[0002] The material collection process is mainly used to collect products. In the process of collecting products, gaseous products will be transported into the material collection container through the process pipeline for storage. In order to ensure that the gaseous products can condense in the container, it is necessary to ensure that the container is at a low temperature of about -25°C. Therefore, in the process, the container is often placed in an air-cooled box, which provides a sufficient low temperature environment.

[0003] Therefore, the metal hose connecting the process pipeline and the receiving container is also in the low temperature environment of the air cooling box. On the one hand, in order to keep the product in the receiving container as much as possible, on the other hand, to prevent the material from condensing in the metal hose and blocking the pipeline, affecting the normal receiving of materials, the metal hose needs to be heated and insulated.

[0004] The existing technical solution is to manually wrap the electric heating tape and PT100 temperature probe around the metal hose every time it is disassembled and assembled, and then wrap the insulation cotton on the outside. The electric heating tape is used to provide heat, the insulation cotton is used to reduce heat dissipation and maintain the hose temperature, and the PT100 temperature probe is used to monitor the temperature of the metal hose, thereby adjusting the heating power of the electric heating tape.

[0005] The problem with this solution is that the winding of the electric companion and the wrapping of the insulation cotton are very troublesome and labor-intensive. In addition, due to the inevitable gap between the insulation cotton and the electric companion, the condensed water under the low temperature outside often enters the electric companion through the gap, causing circuit failure, so that the electric companion needs to be replaced frequently, greatly shortening its service life, increasing production costs, and increasing environmental pollution. Summary of the invention

[0006] The technical problem solved by the present invention is to provide an integrated thermal insulation metal hose, which can reduce the labor of disassembly and assembly and improve the operation stability.

[0007] The technical solution adopted by the present invention is:

[0008] An integrated thermal insulation metal hose comprises a metal hose, a PT100 temperature measuring probe, a heat-insulating tape for fixing the probe, and a waterproof junction box. The PT100 temperature measuring probe is fixed to one end close to the metal hose by the heat-insulating tape for fixing the probe. The PT100 temperature measuring probe is connected to an external waterproof junction box, and the waterproof junction box is connected to an external power supply and control system.

[0009] The PT100 temperature measuring probe is fixed near both ends of the metal hose by using a heat insulating tape to fix the probe.

[0010] The PT100 temperature measuring probe is about 400 mm away from the end.

[0011] The outer layer of the thermal insulation tape is wrapped with two sets of electric heating tapes at a gap of 100 mm.

[0012] The electric heating tape is wrapped and reinforced by heat insulation tape.

[0013] After winding is completed, the wrapped part of the metal hose is heat-melted and shaped using a thermoplastic material to form a thermoplastic fixing layer.

[0014] The PT100 temperature measuring probe includes a probe sensor and a signal line. The probe sensor is fixed by a heat insulating tape. The probe sensor is connected to the signal line. The electric heating tape is connected to a power line. The signal line and the power line are connected to an external waterproof junction box.

[0015] The electric heating belt heats with high power until the temperature signal returned by the PT100 temperature measuring probe reaches the target value.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The integrated thermal insulation metal hose provided by the present invention greatly reduces the manual labor such as the removal and winding of the electrical companion and thermal insulation cotton during the disassembly and assembly of the container, facilitates the operation of personnel, and saves labor costs;

[0018] (2) The integrated thermal insulation metal hose provided by the present invention prevents condensed water from entering the electrical companion along the gap and causing electrical companion failure, reduces the problem of short circuit damage of the electrical companion due to moisture, improves operational stability and safety, and ensures production quality;

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1 As shown, the integrated insulated metal hose provided by the present invention comprises a metal hose (1), a PT100 temperature probe (2), a heat insulating tape (3) for fixing the probe, a heating electric heating tape (4), a heat insulating tape (5), a thermoplastic fixing layer (6) and a waterproof junction box (7), wherein the PT100 temperature probe (2) is fixed near both ends of the metal hose (1) by the heat insulating tape (3) for fixing the probe, and is about 400 mm away from the end, wherein the PT100 temperature probe (2) is placed close to the metal hose and is wrapped with the heat insulating tape (3) for fixing the probe to prevent the probe from loosening, and also to prevent the electric heating from affecting the normal temperature measurement of the PT100 temperature probe (2);

[0027] The outer layer of the thermal insulation tape (3) is wrapped with two sets of electric heating tapes (4) at a gap of 100 mm, and the electric heating tapes (4) are wrapped with thermal insulation tapes (5) to reinforce and reduce heat dissipation. After the wrapping is completed, the wrapped part of the metal hose is heat-melted and shaped using thermoplastic material to form a thermoplastic fixing layer (6).

[0028] like Figure 2As shown, the PT100 temperature measuring probe (2) comprises a probe sensor (201) and a signal line (202); the probe sensor (201) is fixed by a probe fixing heat insulating tape (3); the probe sensor (201) is connected to the signal line (202); the electric heating tape (4) is connected to a power line; the signal line (202) and the power line are connected to an external waterproof junction box (7); and the waterproof junction box (7) is connected to an external power supply and control system.

[0029] The working principle of the present invention is:

[0030] The integrated insulated metal hose is installed at the point of the material receiving container, the process pipeline is connected to the valve of the material receiving container inlet, and the signal line (202) led out from the PT100 temperature probe (2) is connected to the DCS control system; the power line of the electric heating belt 4 is connected to the 220V power supply.

[0031] After installation, the heating power of the integrated insulated metal hose can be controlled by the DCS system. Taking the target temperature of 75°C as an example, the DCS system will control the electric heating belt (4) to heat at high power until the temperature signal returned by the PT100 temperature probe (2) reaches the target value. When the air cooling box starts to cool, the heat dissipation of the integrated insulated metal hose will increase. In order to ensure that the temperature of the metal hose is always stable near the target temperature, the DCS system will use a PID control strategy to adjust the power output of the electric heating belt (4) according to temperature changes.

[0032] The purpose of using two sets of PT100 temperature probes (2) and electric heating belts (4) is to realize one main set and one backup set, and when one set is damaged, it can be switched to the other set for use.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
