Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an evaporative condensing heat exchanger. Background Art

[0002] The evaporative condensing spiral tube heat exchanger is made of one or more groups of spirally wound tubes placed in a shell. Its characteristics are compact structure, larger heat transfer area than straight tubes, and small temperature difference stress, but it is difficult to clean the inside of the tube. It can be used for heating or cooling fluids with higher viscosity.

[0003] For example, the announcement number CN201014753Y discloses a condensing heat exchanger, which is related to the heat exchange device of the gas burner and solves the problem of low thermal efficiency of the existing heat exchange device. A cylinder composed of a heat absorbing tube coiled or arranged axially is arranged in a horizontal cylindrical shell, and there is a gap between the outer wall of the cylinder and the inner wall of the shell. The two ends of the heat absorbing tube are respectively connected to the water inlet joint and the water outlet joint. There is a smoke exhaust port on the shell and a condensed water outlet at the bottom. The cylinder is a combustion chamber for setting the gas burner, and at least one end of the shell has a burner mounting hole.

[0004] However, when the heat exchanger is in use, there is a problem of insufficient stability during lifting and transportation, which makes the equipment casing extremely vulnerable to the risk of bumping, which is not conducive to ensuring its subsequent use efficiency.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an evaporative condensing heat exchanger is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide an evaporative condensing heat exchanger to solve the problem that the heat exchanger proposed in the above background technology has insufficient stability during lifting and transportation when in use, resulting in the risk of the equipment shell being easily bumped, which is not conducive to ensuring its subsequent use efficiency.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an evaporative condensing heat exchanger, comprising an outer shell of a heat exchanger, wherein both upper and lower ends of the outer shell of the heat exchanger are fixedly connected with external fixed rings, rear end of the two external fixed rings are installed with rear vertical shaft rods, upper and lower ends of the rear vertical shaft rods are fixedly connected with horizontal shaft rods, the rear vertical shaft rods are located on the rear side of the outer shell of the heat exchanger, and rotating shaft parts are installed on both left and right ends of the upper and lower sides of the rear vertical shaft rods, and semi-arc locking rings are arranged on the outer ends of the rotating shaft parts, and two pairs of semi-arc locking rings are respectively located on the outside of the outer shell of the heat exchanger.

[0008] Two pairs of semi-arc locking rings are respectively located at the lower sides of the corresponding external fixed rings, and the transverse shaft rod is externally connected with a lifting rope.

[0009] Furthermore, auxiliary rope threading holes are provided at both left and right ends of the transverse shaft rod, and the auxiliary rope threading holes cooperate with the lifting rope.

[0010] Furthermore, a planar stabilizing layer is provided at one end of the semi-arc locking ring away from the outer shell of the heat exchanger, and an anti-slip veneer layer is fixedly connected to the outer end of the planar stabilizing layer.

[0011] Furthermore, a screw is threadedly connected between the two threaded hole rings, and a rubber cover layer is fixedly connected to the upper end of the semi-arc locking ring.

[0012] Furthermore, the rubber cover layer is in contact with the lower outer wall of the external fixed ring, and the lifting rope is externally connected to a crane.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This solution arranges a rear vertical shaft rod at the rear side of the heat exchanger outer shell for facilitating the lifting and transportation of the heat exchanger outer shell, and arranges a pair of semi-arc locking rings outside the rear vertical shaft rod to connect with each other, so that the lifting rope can be bound to the position between the rear vertical shaft rod and the horizontal shaft rod. When the lifting rope is lifted up, the two pairs of semi-arc locking rings provide supporting force under the external fixed ring, making the lifting process more stable and not easy to cause the phenomenon of separation of a single force point;

[0015] 2. At the same time, during transportation, the semi-arc locking ring can be rotated in the opposite direction so that the outer plane stabilizing layer of the semi-arc locking ring contacts the installation base surface, forming a triangular transportation base surface between the installation base surface and the two semi-arc locking rings, so that the outer shell of the heat exchanger is stable and safe during transportation and is not prone to skew. At the same time, in the process of the semi-arc locking ring contacting with the external fixed ring, a rubber cover layer can be set on the semi-arc locking ring to increase the friction surface between the contact surfaces, making the lifting process more stable.

When working, a planar stabilizing layer 10 is provided at one end away from the outer shell 1 of the heat exchanger by setting a semi-arc locking ring 3, and the outer end of the planar stabilizing layer 10 is fixedly connected with an anti-slip veneer layer 9.

[0026] Furthermore, a screw 6 is threadedly connected between the two threaded hole rings 7, and a rubber cover layer 8 is fixedly connected to the upper end of the semi-arc locking ring 3.

[0027] Furthermore, the rubber cover layer 8 is in contact with the lower outer wall of the external fixed ring 2, and the hoisting rope 11 is externally connected to a crane.

[0028] Working principle: When using this kind of evaporative condensing heat exchanger, firstly, this scheme arranges a rear vertical shaft rod 5 on the rear side of the heat exchanger outer shell 1 for easy lifting and transportation of the heat exchanger outer shell 1, and arranges a pair of semi-arc locking rings 3 outside the rear vertical shaft rod 5 to be connected with each other, so that the lifting rope 11 can be bound to the position between the rear vertical shaft rod 5 and the horizontal shaft rod 12.
