Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a jet heat exchange heating system used in high-cold areas. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Its main feature is heat transfer. There are various types of heat exchangers, which can be divided into: floating head heat exchanger, fixed tube sheet heat exchanger, U-shaped tube sheet heat exchanger, plate heat exchanger, etc. The plate heat exchanger is composed of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. During the operation of the equipment, in order to improve the heat exchange efficiency of the equipment, the length of the medium flow channel is increased to achieve high heat exchange efficiency.

[0003] At present, during the installation and use of plate heat exchangers, the flange pipe of the plate heat exchanger is usually connected to the equipment pipe by screws to realize the circulation and heat exchange of liquid. Usually, when the equipment pipe is connected to the flange pipe for installation, workers are required to manually support the connecting pipe, align the pipe openings of the equipment pipe and the flange pipe, and then fix them. If the pipe interface is offset during fixation, the operator is required to loosen the screws again to align the position and fix it, which is more troublesome.

[0004] Therefore, we proposed a jet heat exchange heating system for use in high-altitude cold areas in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a jet heat exchange heating system for use in high-cold areas, so as to solve the problem that during the installation and use of the plate heat exchanger proposed in the above-mentioned background technology, the flange pipe and the equipment pipe are usually connected by screws to realize the circulation and heat exchange of liquid. Usually, when the equipment pipe is connected to the flange pipe for installation, the worker needs to manually support the connecting pipe, align the pipe openings of the equipment pipe and the flange pipe, and then fix them. If the pipe interface is offset during fixing, the operator needs to loosen the screws again to align the position and fix it, which is quite troublesome.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a jet heat exchange heating system for use in high-cold areas, comprising a plate assembly and fixed clamping plates fixedly installed at both ends of the plate assembly, the outer surface of the fixed clamping plate being fixedly installed with clamping bolts through nut threads, a docking assembly being fixedly installed around one end of the plate assembly, the docking assembly being suitable for introducing liquid that needs to be circulated for heat exchange, and a jet heat exchange system being installed in parallel on the plate assembly;

[0007] The docking component includes a flange nozzle and a flow-through pipe installed at one end of the flange nozzle through a pre-fixing mechanism.

[0008] Preferably, the flow-through pipe includes a T-shaped flange pipe and an external thread disc fixedly installed at one end of the outer wall of the T-shaped flange pipe.

[0009] Preferably, the pre-fixing mechanism includes a round block and an inner embedding groove opened in the middle of one end of the round block, and a penetrating groove is opened in the middle of the bottom surface of the inner embedding groove.

[0010] Preferably, an anti-slip rubber layer is embedded around the bottom surface of the inner embedding groove, and round grooves are opened on both sides of one end of the round block.

[0011] Preferably, connecting long rods are fixedly installed on the other two sides of one end of the round block. An internal thread ring is fixedly installed at one end of the connecting long rod. Corresponding grooves are opened on both sides of one end of the internal thread ring. A long screw rod is movably installed in the inner cavities of the corresponding grooves and the round grooves. A positioning nut is threadedly installed at one end of the long screw rod.

[0012] Preferably, the jet heat exchange system is electrically connected to the PLC control system. The PLC control system is electrically connected to the electric control valve. The electric control valve is electrically connected to the booster pump. The booster pump is electrically connected to the flow meter.

[0013] Preferably, the PLC control system is electrically connected to the pressure sensor. The pressure sensor is electrically connected to the temperature sensor.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The operator passes one end of the flange nozzle through the penetrating groove, so that the flange nozzle is sleeved in the inner cavity of the inner embedding groove. When docking and fixing the flange nozzle and the flow-through pipe, the T-shaped flange pipe is passed through the internal thread ring. Due to the setting of the connecting long rod, there will be a certain position in the contact between the flange nozzle and the flow-through pipe. At the same time, the external thread disc abuts against one end of the internal thread ring. At this time, the flow-through pipe is rotated to drive the external thread disc to be screwed into the inner cavity of the internal thread ring. While the external thread disc is being screwed in, the external thread disc will drive one end of the T-shaped flange pipe to press against one end of the flange nozzle, directly pre-fixing the flange nozzle and the flow-through pipe.

A penetration groove 533 is opened in the middle of the bottom surface of the embedded groove 532, and one end of the flange pipe 51 is movably installed in the inner cavities of the embedded groove 532 and the penetration groove 533.

[0026] A non-slip rubber layer 534 is embedded around the bottom surface of the embedded groove 532. Circular grooves 535 are formed on both sides of one end of the circular block 531, and one end of the flange pipe 51 contacts the non-slip rubber layer 534.

[0027] On the other two sides of one end of the circular block 531, connecting long rods 536 are fixedly installed. One end of the connecting long rod 536 is fixedly installed with an internally threaded ring 537, and corresponding grooves 538 are formed on both sides of one end of the internally threaded ring 537.

[0028] A long screw 539 is movably installed in the inner cavities of the corresponding groove 538 and the circular groove 535. A positioning nut is threadedly installed at one end of the long screw 539, and the external thread disc 522 is threadedly connected in the inner cavity of the internally threaded ring 537.

[0029] In this embodiment: When the operator installs the flange pipe 51, one end of the flange pipe 51 passes through the penetration groove 533, so that the flange pipe 51 is sleeved in the inner cavity of the embedded groove 532. When the flange pipe 51 and the flow pipe 52 are butted and fixed, the T-shaped flange pipe 521 passes through the internally threaded ring 537. With the arrangement of the connecting long rod 536, there will be a certain position when the flange pipe 51 and the flow pipe 52 contact. At the same time, the external thread disc 522 abuts against one end of the internally threaded ring 537.
