Description

Technical Field

[0001] The utility model relates to the field of heat exchangers, in particular to a detachable plate heat exchanger which is easy to clamp. Background Art

[0002] The traditional assembly of detachable plate heat exchangers usually involves opening a U-shaped groove on the clamping plate to facilitate the placement of the side clamping rod, and then fixing the side clamping rod in the U-shaped groove with a nut. On the one hand, this form makes the installation of the detachable plate heat exchanger more cumbersome and inconvenient. On the other hand, the contact area between the side clamping rod and the heat exchange plate is small, and its clamping effect is poor. During long-term use, the heat exchange plate cannot be effectively clamped. In addition, the upper and lower support rods of the traditional detachable plate heat exchanger are cylindrical structures, resulting in a smaller support surface of the support rods for the heat exchange plate, which makes it easy for the heat exchange plate to be offset during assembly, and is not conducive to the rapid assembly of the detachable plate heat exchanger.

A push rod is provided at the front end of the cylinder. A clamping plate is connected to the front end of the push rod. Rectangular through grooves are provided at the upper and lower ends of the clamping plate. Two guide plates are arranged between the front end plate and the rear end plate at intervals according to the upper and lower positions, and the guide plates pass through the rectangular through grooves of the clamping plates.

[0004] Preferably, the front end of the guide plate is provided with a front screw, the rear end of the guide plate is provided with a rear screw, a nut is provided on the rear screw, the length of the front screw is shorter than that of the rear screw, and the guide plate is configured as a rectangular plate structure.

[0005] Preferably, a thread groove is provided on the front end plate.

[0006] Preferably, a circular through groove is provided on the rear end plate.

[0007] The beneficial effects of the present invention are as follows: the present invention has a reasonable structural design, is easy to use, can simply and quickly clamp and fix the heat exchange plates, and can also make the heat exchange plates clamped more firmly. In addition, the present invention can also quickly disassemble and assemble the plate heat exchanger. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0013] Any feature in this specification, unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0014] like Figure 1 、 2 The shown embodiment shows a detachable plate heat exchanger that is easy to clamp, comprising a front end plate 1, a rear end plate 2 and two guide plates 3. The front end plate 1 and the rear end plate 2 have the same structure. A cylinder 5 is embedded in the front end plate 1 near the upper and lower ends. A push rod 6 is provided at the front end of the cylinder 5. A clamping plate 4 is connected to the front end of the push rod 6. Rectangular through grooves are provided at the upper and lower ends of the clamping plate 4. The two guide plates 3 are spaced between the front end plate 1 and the rear end plate 2 according to the relationship between the upper and lower positions. The guide plate 3 passes through the rectangular through groove of the clamping plate 4.

[0015] The front end of the guide plate 3 is provided with a front screw 8, and the rear end of the guide plate 3 is provided with a rear screw 9. A nut 7 is provided on the rear screw 9. The length of the front screw 8 is shorter than that of the rear screw 9. The guide plate 3 is configured as a rectangular plate structure.

[0016] The front end plate 1 is provided with a thread groove.

[0017] The rear end plate 2 is provided with a circular through groove.

[0018] During use, the nut 7 is loosened to remove the rear end plate 2 from the guide plate 3, and then several heat exchange plates are installed between the upper and lower guide plates 3 in sequence. After the heat exchange plates are installed, the rear end plate 2 is reinstalled on the guide plate 3 and the nut 7 is tightened to fix it. Then, the push rod 6 is pushed forward by the cylinder 5, which further drives the clamping plate 4 to move forward, thereby clamping and fixing the heat exchange plates.

[0019] The guide plate 3 is configured as a rectangular plate structure, which can increase the contact surface between the guide plate 3 and the heat exchange plate, thereby making the heat exchange plate more stable to install and less likely to become scattered, and also enables the guide plate 3 to play a good supporting role.

[0020] The provision of the front screw 8 can facilitate fixing the knob of the guide plate 3 on the front end plate 1 ; the provision of the rear screw 9 can facilitate fixing the rear end plate 2 after it is installed on the guide plate 3 .

[0021] The beneficial effects of the present invention are as follows: the present invention has a reasonable structural design, is easy to use, can simply and quickly clamp and fix the heat exchange plates, and can also make the heat exchange plates clamped more firmly. In addition, the present invention can also quickly disassemble and assemble the plate heat exchanger.

[0022] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
