Description

Technical Field

[0001] The utility model relates to the field of plate heat exchanger maintenance, in particular to a nut removal tool for a plate heat exchanger. Background Art

[0002] At present, the pure water coolers used in some factories are integral skid-mounted products, in which the plate heat exchanger is arranged. The overall installation is compact, and the heat sink clamping bolts of the plate heat exchanger are reserved longer (that is, long-rod bolts are used). When repairing and cleaning the plate heat exchanger, the long clamping bolts make it impossible to use an electric wrench or ratchet wrench directly. In addition, the maintenance space is cramped, resulting in troublesome and laborious repair and maintenance.

[0003] Therefore, there is an urgent need for a plate heat exchanger nut removal tool that can solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a plate heat exchanger nut removal tool to solve the problems existing in the above-mentioned prior art.

[0005] To achieve the above purpose, the present invention provides the following solutions:

[0006] The utility model provides a nut removal tool for a plate type heat exchanger, comprising a bolt sleeve, wherein two ends of the bolt sleeve are respectively a nut collar and a driving end, and a steel pipe is coaxially welded between the nut collar and the driving end.

[0007] Preferably, a through hole is opened on the side of the steel pipe, and a lever is detachably inserted into the through hole.

[0008] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0009] The utility model provides a plate heat exchanger nut removal tool, including a bolt sleeve, wherein the two ends of the bolt sleeve are respectively a nut collar and a driving end, and a steel pipe is coaxially welded between the nut collar and the driving end; when in use, the nut collar can be sleeved on the nut of the heat sink clamping bolt of the plate heat exchanger, and the reserved longer bolt rod can be hidden in the steel pipe. An electric wrench or a ratchet wrench can be inserted into the driving end to easily twist the nut, so that the long-rod bolt can be removed without space restrictions and the maintenance efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0011] Figure 1 The utility model provides a structural schematic diagram of a plate heat exchanger nut removal tool. DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] The purpose of the utility model is to provide a plate heat exchanger nut removal tool to solve the problems existing in the prior art.

[0014] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] Example 1:

[0016] This embodiment provides a plate heat exchanger nut removal tool, such as Figure 1 As shown, it includes a bolt sleeve, which can adopt a standard bolt sleeve on the market. It can be cut in the middle to obtain a nut ring 1 and a driving end 2. A steel pipe 3 is coaxially welded between the nut ring 1 and the driving end 2, thereby constituting the disassembly tool as a whole. The length of the steel pipe 3 is suitable for all bolts to be accommodated therein. When in use, the nut ring is placed on the nut of the heat sink tightening bolt of the plate heat exchanger, and then an electric wrench or ratchet wrench is inserted into the interface of the driving end to quickly disassemble and assemble the nut of the long-rod bolt.

[0017] As an implementation scheme, a through hole 4 is opened on the side of the steel pipe 3, and a lever 5 is detachably inserted into the through hole 4. When additional force is needed, the lever 5 is inserted into the through hole 4 and can be rotated to apply force.

[0018] The utility model provides a plate heat exchanger nut removal tool, which can facilitate maintenance, shorten maintenance time, improve work efficiency, and effectively reduce labor costs.

[0019] This utility model uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only used to help understand the method and core concept of this utility model. At the same time, for those skilled in the art, according to the concept of this utility model, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
