Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment, and in particular to a heat treatment device for heat exchange. Background Technology

[0002] A heat exchanger is a device that transfers heat from one fluid to another. There are many types of heat exchangers, and plate heat exchangers are one of them. However, when cleaning the plates of a plate heat exchanger, the plates need to be disassembled. Plate heat exchangers are fixed by multiple bolt and nut assemblies during assembly. When it is necessary to disassemble the bolt and nut assembly, one end of the bolt and nut assembly needs to be fixed, and then the nut at the other end of the bolt and nut assembly needs to be rotated with a tool. However, this is quite troublesome and requires the cooperation of multiple people to complete. Utility Model Content

[0003] The main objective of this invention is to provide a heat treatment device for heat exchange, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A heat treatment device for heat exchange includes a fixed clamping plate and a limiting plate. The limiting plate is provided on the front surface of the fixed clamping plate. Flange interfaces are fixedly installed on the front surface of the fixed clamping plate near the upper and lower sides. A support plate is installed at the rear of the fixed clamping plate. A guide rod is fixedly installed between the support plate and the fixed clamping plate, above and below. A threaded rod is movably installed on the front surface of the fixed clamping plate, at the middle. A movable plate is sleeved on the guide rod. A bolt and nut assembly is inserted between the movable plate and the fixed clamping plate at the edge. A plate is sleeved on the guide rod between the movable plate and the fixed clamping plate.

[0006] More preferably, the limiting plate has a hexagonal opening on its surface and at its edge position that is adapted to the bolt and nut assembly, a threaded hole on its surface and at its center, and sleeve openings on its surface and near its upper and lower sides.

[0007] More preferably, a knob is fixedly mounted on the front surface of the threaded rod, and a mounting block is fixedly mounted on the rear surface of the threaded rod.

[0008] More preferably, a pad is fixedly installed on the front surface of the fixing clamp near the edge, an embedding groove is formed on the front surface of the fixing clamp in the middle, a rotating groove is formed on the rear surface of the embedding groove, a threaded groove is formed on the rear surface of the embedding groove near the edge, a cover plate is fixedly embedded inside the embedding groove, a fastener is embedded on the front surface of the cover plate near the edge, and the rear end of the fastener is embedded in the threaded groove.

[0009] In a further preferred embodiment, the rear end of the threaded rod passes through the threaded hole and the cover plate and is embedded in the rotating groove. The cover plate is fixedly embedded in the groove by fasteners. The bolt and nut assembly passes through the pad and the hexagonal opening. The front end of the guide rod passes through the fixing clamp and the limiting plate. The front end of the guide rod is threaded with a fastening nut.

[0010] Compared with the prior art, this utility model proposes a heat treatment device for heat exchange, which has the following beneficial effects:

[0011] In this invention, by setting a fixed clamping plate, a limiting plate, and a threaded rod to cooperate with each other, when it is necessary to disassemble the bolt and nut assembly, the knob is rotated, and the knob drives the threaded rod to rotate. At this time, the limiting plate will move forward. When the limiting plate moves forward, the hexagonal opening of the limiting plate will fit onto the front bolt surface of the bolt assembly and the fastening nut surface at the front end of the guide rod. Since the front end of the bolt and nut assembly is limited, it is only necessary to use a tool to directly rotate the nut at the rear end of the bolt and nut assembly. This eliminates the need for a separate operator to limit the front end of the bolt and nut assembly. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1-4 As shown, a heat treatment device for heat exchange includes a fixed clamping plate 1 and a limiting plate 2. The limiting plate 2 is provided on the front surface of the fixed clamping plate 1. Flange interfaces 4 are fixedly installed on the front surface of the fixed clamping plate 1 near the upper and lower sides. A support plate 6 is installed behind the fixed clamping plate 1. A guide rod 7 is fixedly installed between the support plate 6 and the fixed clamping plate 1, above and below. A threaded rod 3 is movably installed on the front surface of the fixed clamping plate 1, in the middle. A movable plate 5 is sleeved on the guide rod 7. A bolt and nut assembly 9 is inserted between the movable plate 5 and the fixed clamping plate 1, at the edge position. A plate 8 is sleeved on the guide rod 7, located between the movable plate 5 and the fixed clamping plate 1.

[0021] In a preferred embodiment: the surface of the limiting plate 2 and the edge position are provided with a hexagonal opening 201 that is adapted to the bolt and nut assembly 9, the surface of the limiting plate 2 and the center position are provided with a threaded hole 202, and the surface of the limiting plate 2 and the upper and lower sides are provided with a sleeve opening 203.

[0022] In the above structure, when the knob 301 is rotated, the threaded rod 3 will be driven to rotate. Since the threaded hole 202 of the limiting plate 2 is fitted on the threaded rod 3, the rotating threaded rod 3 can cause the limiting plate 2 to move forward, so that the hexagonal opening 201 is fitted on the front end of the bolt and nut assembly 9. This can limit the front end. When disassembling the bolt and nut assembly 9, it is only necessary to rotate and disassemble the nut at the rear end.

[0023] In a preferred embodiment: a knob 301 is fixedly mounted on the front surface of the threaded rod 3, and a mounting block 302 is fixedly mounted on the rear surface of the threaded rod 3.

[0024] In a preferred embodiment: a pad 101 is fixedly installed on the front surface of the fixed clamping plate 1 near the edge; an embedding groove 102 is formed on the front surface of the fixed clamping plate 1 in the middle; a rotating groove 103 is formed on the rear surface of the embedding groove 102; a threaded groove 104 is formed on the rear surface of the embedding groove 102 near the edge; a cover plate 105 is fixedly embedded inside the embedding groove 102; a fastener 106 is embedded on the front surface of the cover plate 105 near the edge; and the rear end of the fastener 106 is embedded in the threaded groove 104.

[0025] In the above structure, since the pad 101 protrudes from the front surface of the fixing plate 1, when the bolt and nut assembly 9 is installed, the front end of the bolt and nut assembly 9 protrudes from the limiting plate 2. During the installation of the bolt and nut assembly 9, the front end of the bolt and nut assembly 9 must always be aligned with the hexagonal opening 201 so that when the limiting plate 2 moves forward, the hexagonal opening 201 can accurately fit onto the front end of the bolt and nut assembly 9 and limit its movement.

[0026] In a preferred embodiment: the rear end of the threaded rod 3 passes through the threaded hole 202 and the cover plate 105 and is embedded in the rotating groove 103. The cover plate 105 is fixedly embedded in the embedding groove 102 by fasteners 106. The bolt and nut assembly 9 passes through the pad 101 and the hexagonal opening 201. The front end of the guide rod 7 passes through the fixing clamp 1 and the limiting plate 2. The front end of the guide rod 7 is threaded with a fastening nut.

[0027] In the above structure, since the rear end of the threaded rod 3 is embedded in the rotating groove 103, and the mounting block 302 is fixed on the rear surface of the threaded rod 3, the mounting block 302 is embedded in the rotating groove 103, and the cover plate 105 is fixedly embedded in the mounting groove 102. Therefore, the mounting block 302 cannot be detached from the rotating groove 103. When the threaded rod 3 rotates, the mounting block 302 can only rotate in the rotating groove 103, so that the threaded rod 3 can remain stable when rotating.

[0028] When using this invention, if it is necessary to disassemble the bolt and nut assembly 9, rotate the knob 301. The knob 301 drives the threaded rod 3 to rotate, at which time the limiting plate 2 will move forward. When the limiting plate 2 moves forward, the hexagonal opening 201 of the limiting plate 2 will fit onto the front bolt surface of the bolt and nut assembly 9 and the fastening nut surface of the front end of the guide rod 7. Since the front end of the bolt and nut assembly 9 is limited, it is only necessary to use a tool to directly rotate the nut at the rear end of the bolt and nut assembly 9. This way, it is not necessary for a separate operator to limit the front end of the bolt and nut assembly 9. After the bolt and nut assembly 9 is disassembled, rotate the knob 301 in the opposite direction to reverse the threaded rod 3. This allows the limiting plate 2 to move back to its original position. Finally, remove the fastening nut at the front end of the guide rod 7, and the guide rod 7 can be separated from the fixing clamp 1, thereby allowing the plate 8 on the guide rod 7 to be removed.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
