Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchanger assembly, in particular to a plate heat exchanger sealing gasket quick assembly device. Background Art

[0002] The assembly of a plate heat exchanger includes steps such as component inspection, tool preparation, frame installation, plate installation, gasket installation, clamping device installation, appearance inspection, pressure testing, and commissioning. First, place the frame of the plate heat exchanger in a suitable position on the assembly site to ensure that the frame is stable and firm. Check each connection part of the frame to ensure that the connection is firm and there is no looseness. Starting from one end of the frame, install the plates in sequence, insert the guide rods of the plates into the guide grooves of the frame, ensure that the plates are installed in the correct direction, and install gaskets between each plate. The installation position of the gaskets must be accurate to ensure that they completely cover the sealing surface between the plates. After all plates and gaskets are installed, install the clamping device. After all assembly is completed, check and debug.

[0003] In the current existing technology, the sealing gaskets of plate heat exchangers can be divided into placement type, adhesive type and buckle type sealing gaskets. Different types of plate heat exchangers need to select corresponding types of sealing gaskets. When installing the buckle type sealing gaskets, the staff needs to manually open the sealing gaskets, then put the opened sealing gaskets on the plate and loosen them. The sealing gaskets recover under the action of their own elasticity and buckle in the sealing groove on the plate, which results in a slow installation speed of the buckle type sealing gaskets. Therefore, a quick assembly device for the sealing gaskets of plate heat exchangers is proposed to solve the above problems. Utility Model Content

It solves the problem that when installing the press-type sealing gasket, the staff needs to manually open the sealing gasket, then put the opened sealing gasket on the plate and loosen it. The sealing gasket recovers under the action of its own elasticity and is pressed into the sealing groove on the plate, thereby causing the installation of the press-type sealing gasket to be slow.

A linear drive for controlling the up and down movement of the abutment columns is installed inside the mounting frame, and the telescopic end of the linear drive is fixedly connected to the abutment column. A stabilizing bracket is fixedly installed on the outer surface of the linear drive, and the bottoms of the four arc-shaped plates are fixedly connected to guide plates slidably connected to the stabilizing bracket.

The outer surfaces of the four arc-shaped plates are slidably connected with a pushing plate for pushing the sealing gasket, and the four mounting hoops are equipped with a propulsion component for controlling the movement of the pushing plate.

[0008] Furthermore, a circular groove is formed on the top of the installation frame, the protective tube is fixedly connected to the inner wall of the circular groove, and one end of the protective tube passes through and extends to the outside of the installation frame, and the installation frame is welded to the cover.

[0009] Furthermore, the abutting column includes a connecting tube and a tapered column, the bottom of the tapered column is fixedly connected to the top of the connecting tube, and the telescopic end of the linear actuator is fixedly connected to the inner top wall of the connecting tube.

[0010] Furthermore, the stabilizing bracket includes a connecting ring and four guide rods. The connecting ring is fixedly mounted on the outer surface of the linear drive. One end of the four guide rods is fixedly connected to the connecting ring, and the other ends of the four guide rods are respectively fixedly connected to the inner wall of the mounting frame.

[0011] Furthermore, a connecting sleeve is fixedly installed on the bottom of each of the two guide plates, and the four connecting sleeves are respectively sleeved on the outer surfaces of the four guide rods, and the inner walls of the connecting sleeves are slidably connected to the outer surfaces of the guide rods.

[0012] Furthermore, the propulsion component includes four electric push rods, which are fixedly mounted on four mounting hoops respectively, and the telescopic ends of the four electric push rods are fixedly connected to the bottoms of four pushing plates respectively.

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

The four electric push rods in the pushing component 48 are extended and drive the pushing plate 49 to move, so that the moving pushing plate 49 is used to push the sealing gasket into the plate sealing groove to complete the buckling installation.
