Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a dustproof plate type heat exchanger. Background Art

[0002] A plate heat exchanger is a device used for heat exchange and is widely used in industrial and commercial applications such as refrigeration, heating, chemical engineering, and food processing. Compared to traditional shell-and-tube or shell-and-tube heat exchangers, plate heat exchangers have the advantages of being smaller and more efficient.

[0003] However, when the plate heat exchanger is used for a long time, a large amount of dust will adhere to it. Compared with the external dust, which is easier to clean, the dust in the gaps between the heat exchange plates is often difficult to clean. Utility Model Content

[0004] The purpose of the utility model is to address the problems existing in the background technology and to propose a dustproof plate type heat exchanger.

[0005] The technical solution of the present utility model is: a dust-proof plate heat exchanger, comprising a plurality of heat exchange plates, a dust-proof structure being installed between two adjacent heat exchange plates, the dust-proof structure comprising a rubber pad fixedly mounted on the heat exchange plate on one side, and a baffle structure fixedly mounted on the heat exchange plate on the other side, the baffle structure comprising an ash collection chamber.

[0006] Preferably, the baffle structure includes a first rubber baffle and a second rubber baffle, and the first rubber baffle and the second rubber baffle form the ash collecting chamber.

[0007] Preferably, the rubber pad is glued to the heat exchange plate on one side, and the first rubber baffle is glued to the heat exchange plate on the other side and covers the heat exchange plate on one side.

[0008] Preferably, the rubber pad has a stress-bearing groove at the beginning, and an aluminum alloy pressing rod is fixedly installed on the heat exchange plate on the other side, and the aluminum alloy pressing rod is matched with the stress-bearing groove.

[0009] Preferably, magnetic sleeves are installed on both sides of the second rubber baffle, and a guide rod is provided through the magnetic sleeve, and both ends of the guide rod are connected to the heat exchanger frame.

[0010] Compared with the existing technology, the beneficial effect of the present invention is: this solution installs a dust-proof structure between adjacent heat exchange plates, so that the adjacent heat exchange plates are shielded and a dust collecting cavity is formed between the two. Dust enters the dust collecting cavity and is collected, which makes it easier to clean the dust later. In addition, this solution has a simple structure and does not require structural improvements to the heat exchanger. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] Refer to the attached Figure 1-Figure 2 A dustproof plate heat exchanger includes multiple heat exchange plates 1. A dustproof structure 2 is installed between two adjacent heat exchange plates 1. The dustproof structure 2 includes a rubber pad 21 fixedly installed on the heat exchange plate 1 on one side, and a baffle structure 23 fixedly installed on the heat exchange plate 1 on the other side. The baffle structure 23 includes an ash collecting chamber 24.

[0016] Specifically, the baffle structure 23 includes a first rubber baffle 231 and a second rubber baffle 232 , and the first rubber baffle 231 and the second rubber baffle 232 form an ash collecting chamber 24 ;

[0017] like Figure 2 As shown, the rubber pad 21 is glued to the heat exchange plate 1 on one side, and the first rubber baffle 231 is glued to the heat exchange plate 1 on the other side and covers the heat exchange plate 1 on one side, so that the gap between the two heat exchange plates 1 is blocked by the first rubber baffle 231, so that dust can only enter the ash collecting chamber 24.

[0018] Specifically, the rubber pad 21 has a stress groove 25 at the beginning, and an aluminum alloy pressing rod 22 is fixedly installed on the heat exchange plate 1 on the other side. The aluminum alloy pressing rod 22 cooperates with the stress groove 25. When the two heat exchange plates 1 are installed and fitted together, the aluminum alloy pressing rod 22 will enter the stress groove 25 and press it, thereby ensuring the stability of the rubber pad 21.

[0019] In this embodiment, it should also be noted that magnetic sleeves 4 are installed on both sides of the second rubber baffle 232, and a guide rod 3 is provided through the magnetic sleeve 4. The two ends of the guide rod 3 are connected to the heat exchanger frame. The magnetic sleeve 4 is inserted into the guide rod 3. The guide rod 3 will be adsorbed on the magnetic sleeve 4, so that the second rubber baffle 232 maintains this posture to prevent it from being deformed due to long-term use. During the specific installation, before installing multiple heat exchange plates 1, the dustproof structure 2 can be installed on the adjacent heat exchange plates 1, and then the heat exchange plates 1 can be installed normally.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
