Description

Technical Field

[0001] The utility model relates to the technical field of air drying equipment, in particular to a high-efficiency air drying device for a heat exchanger after a pressure test. Background Art

[0002] After the heat exchanger is processed, a pressure test operation needs to be carried out, that is, the heat exchanger is immersed in water, one end is sealed, and the other end is ventilated to check whether there is any gas leakage. After the pressure test, the immersed heat exchanger needs to be dried. The existing technology uses oven drying, which has high energy consumption and low efficiency.

[0003] The air knife can be driven by a vortex fan or a high-pressure centrifugal fan (instead of high-energy compressed air). It uses different fans and air knives to blow away dust and moisture on the surface of objects in time. In the industrial field, air knives are widely used for blowing water and dust removal, such as blowing away dust and moisture on planes such as steel plates and aluminum alloy profiles, blowing away moisture on the surface of beverage bottles, packaging cans, etc., blowing away impurities and dust on the surface of products, residual liquid, moisture on the outer packaging, and cleaning conveyor belts. Under the condition of compressed air supply, air knives can perfectly meet these applications.

[0004] Therefore, a wind knife dryer proposed in the patent with publication number CN219674722U can dry the bottle body by rotating to ensure that no moisture remains around the bottle body. Existing dryers usually fix the components to be blown and pass them through the wind knife or the air duct formed by the wind knife to dry the components to be blown in all directions. This drying method is more practical for items with relatively regular volume and shape, but for heat exchangers, because of their large size, they are inconvenient to be fixed and transported, and are full of narrow gaps, the existing dryers cannot effectively dry them while quickly transporting them. Utility Model Content

[0005] The utility model aims to provide a high-efficiency air-drying device for a heat exchanger after a pressure test, so as to solve the technical problems that the existing blow dryer cannot transport the heat exchanger quickly and cannot effectively dry it.

[0006] The embodiments of the present invention are implemented by the following technical solutions:

[0007] A high-efficiency air-drying device for a heat exchanger after a pressure test comprises a plurality of groups of air knives for drying the heat exchanger, and also comprises a baffle plate for forming an air duct with the air knives. A conveyor belt for transporting the heat exchanger is arranged above the air duct, and the conveyor belt is provided with a rotating disk for connecting the heat exchanger, and the rotating disk is rotatably connected to a hook for fixing the heat exchanger.

[0008] Preferably, the air duct is divided into two sections, which are respectively arranged in the conveying section and the return section of the conveyor belt; and the wind knife is arranged between the conveying section and the return section.

[0009] Preferably, the wind knife is provided with a connecting pipe for connecting to a main air duct, and the main air duct is connected to a fan for providing compressed air.

[0010] Preferably, the main air duct is divided into two sections, which respectively provide compressed air for the two sections of air ducts; and the two sections of the main air duct are provided with elbows interconnected at the ends and with connecting ports interconnected in the middle.

[0011] Preferably, it also includes a ground bracket for supporting the main air duct and the air knife and a suspended bracket for supporting the conveyor belt, and the suspended bracket is provided with a fixing part connected to the conveyor belt.

[0012] Preferably, it also includes a loading platform and an unloading platform respectively arranged at the conveying section and the return section for hanging up the heat exchanger and removing the heat exchanger.

[0013] Preferably, the hook comprises a rotating shaft and two sets of sub-hook frames rotatably arranged on the rotating shaft, and the sub-hook frames are provided with plug hooks for hanging the heat exchanger.

[0014] Preferably, the wind knife is also provided with a wind slot for secondary air collection.

[0015] By adopting this technical solution, the hook of the hook can be inserted into the gap between the heat exchange tubes of the two sections of the heat exchanger, the heat exchanger can be suspended and hoisted, and then the conveyor belt drives the hook to pass through the air duct. During the process of passing through the air duct, the air knife sprays compressed air on the surface of the heat exchanger. While drying the heat exchanger, the hook and the heat exchanger are blown to rotate through the rotating disk, so that the heat exchanger is fully dried in all directions.

[0016] And the conveyor belt conveying section and return section are fully utilized, and air ducts are set in both sections to dry them. The integration is high, which ensures sufficient drying while reducing the site area occupied by the equipment.

[0017] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0018] 1. The utility model inserts the hook of the hook into the gap between the two sections of the heat exchange tube of the heat exchanger, hangs the heat exchanger, and then the conveyor belt drives the hook through the air duct to realize the convenient transportation of the heat exchanger;

[0019] 2. When the heat exchanger of the utility model passes through the air duct, the air knife sprays compressed air on the surface of the heat exchanger. While drying, the hook and the heat exchanger rotate through the rotating disk to fully dry the heat exchanger in all directions;

[0020] 3. The utility model makes full use of the conveying section and the return section of the conveyor belt, and air ducts are set in both sections to dry them. It has a high degree of integration, which ensures sufficient drying while reducing the site area occupied by the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
