Description

Technical Field

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

[0002] Plate heat exchanger is a highly efficient and compact heat exchange device, which is composed of a series of metal sheets with specific corrugated shapes. Thin rectangular channels are formed between these metal sheets, so that the fluid can flow in these channels and exchange heat through the plates. Therefore, plate heat exchanger is an ideal device for heat exchange between liquid and liquid, liquid and gas.

[0003] In the prior art, a Chinese patent document with publication number CN209945090U proposes a detachable plate heat exchanger. When the plate group is disassembled and assembled, the patent only needs to separate the front connecting rod and the rear connecting rod, and then move the movable end plate to remove the part of the plate that needs to be removed. The plates that do not need to be replaced can still be placed in the heat exchanger. The disassembly and installation are convenient and quick, and the plates are not easily damaged due to disassembly. The above patent document is consistent with the prior art in that after the installation of the plate is completed, it is necessary to rotate multiple bolts to move the clamping plate to complete the clamping of the plate. However, by using multiple bolts, the plate group can be easily removed. The method of using a bolt to move the movable end plate to clamp the plate has the following disadvantages: 1. The plate clamping operation time is long, which reduces work efficiency; 2. When the bolts at different positions are rotated a different number of times, the clamping plate will be skewed, resulting in a gap between the plate and the plate, which will cause liquid leakage inside the plate. Therefore, we disclose a plate installation structure for a plate heat exchanger to meet the actual needs of the existing plate heat exchanger plate installation and clamping structure not being provided with a quick clamping assembly, resulting in a long time for plate clamping, and the different clamping forces of different parts of the clamping plate causing liquid leakage inside the plate. Summary of the invention

[0004] In view of this, the purpose of the utility model is to propose a plate heat exchanger plate installation structure to solve the problem that the existing plate heat exchanger plate installation and clamping structure is not provided with a quick clamping assembly, resulting in a long time spent on plate clamping and the different clamping forces of different parts of the clamping plate lead to leakage of liquid inside the plate.

The plate clamping assembly includes a support frame fixed to one side of the plate heat exchanger body, and a locking assembly for limiting the plate clamping assembly is provided on one side of the upper end of the support frame.

[0006] Preferably, the plate pressing assembly includes a first connecting rod and a second connecting rod, and the first connecting rod is rotatably connected to the second connecting rod.

[0007] Preferably, one end of the first connecting rod is rotatably connected to the pressure rod, and the second connecting rod is rotatably connected to the upper end of the support frame.

[0009] Preferably, a handle for quickly rotating the second connecting rod is fixedly connected to the upper end of the second connecting rod.

[0010] Preferably, the upper and lower ends of the middle portion of one end surface of the clamping plate are fixedly connected with guide rods, and the two guide rods both penetrate the plate heat exchanger body and are slidably connected to the plate heat exchanger body.

[0011] Preferably, the locking assembly comprises a fixed toothed disc and a movable toothed disc, the fixed toothed disc is fixedly connected to the first connecting rod, and the fixed toothed disc and the movable toothed disc are meshed with each other.

[0012] Preferably, telescopic springs are fixedly connected to both sides of the upper ends of one end surface of the support frame, one side of the two telescopic springs is fixedly connected to a connecting plate, and one side of the connecting plate is provided with a pulling rod for facilitating pulling of the connecting plate.

[0015] The beneficial effects of the utility model: when the plate installation structure of the plate heat exchanger is in use, after the installation of the plate is completed, the locking assembly is first pulled, and the plate clamping assembly provided can quickly move the clamping plate used to clamp the plate, which greatly reduces the plate clamping operation time and improves work efficiency, and the clamping plate is moved by the pressure rod and is not prone to skew.

A plate pressing assembly 2 for quickly moving the pressing plate 8 is provided on one side of the plate heat exchanger body 1. The plate pressing assembly 2 includes a support frame 7 fixed to one side of the plate heat exchanger body 1, and a locking assembly 14 for limiting the plate pressing assembly 2 is provided on one side of the upper end of the support frame 7. When the plate installation structure of the plate heat exchanger is in use, when the plate is completed After the installation of the plate, first pull the locking assembly 14. The plate clamping assembly 2 can quickly move the clamping plate 8 used to lock the plate, which greatly reduces the plate clamping operation time and improves work efficiency. The clamping plate 8 is moved by the pressure rod 5 and is not easy to tilt. When the clamping plate 8 is moved to the specified position, release the locking assembly 14 to complete the limiting work of the plate clamping assembly 2, so that the plate clamping assembly 2 is not easy to shake, maintain the clamping force of the clamping plate 8 on the plate, and reduce the possibility of leakage of liquid inside the plate due to insufficient clamping force.

[0026] Further, such as Figure 1 to Figure 2 As shown, the plate clamping assembly 2 includes a first connecting rod 3 and a second connecting rod 15, the first connecting rod 3 is rotatably connected to the second connecting rod 15, one end of the first connecting rod 3 is rotatably connected to the pressure rod 5, the second connecting rod 15 is rotatably connected to the upper end of the support frame 7, the end of the pressure rod 5 away from the clamping plate 8 passes through the support frame 7 and is slidably connected to the support frame 7, the upper end of the second connecting rod 15 is fixedly connected to a handle 4 for quickly rotating the second connecting rod 15, the middle of the upper and lower ends of one side end surface of the clamping plate 8 are fixedly connected to a guide rod 6, and the two guide rods 6 both penetrate the plate heat exchanger body 1 and are slidably connected to the plate heat exchanger body 1. When the pressing plate 8 needs to be moved, the second connecting rod 15 is rotated by the handle 4, the second connecting rod 15 is rotatably connected to the first connecting rod 3, and the first connecting rod 3 is fixedly connected to the support frame 7. Since one end of the second connecting rod 15 is rotatably connected to the pressure rod 5, and the two ends of the pressure rod 5 are respectively slidably connected to the plate heat exchanger body 1 and the support frame 7, when the second connecting rod 15 is rotated, the pressure rod 5 will slide back and forth to complete the rapid pressing of the plate.
