Description

Technical Field

[0001] This invention relates to the field of rotary pressure filter technology, and more particularly to a tooling for disassembling and installing a filter press isolation unit. Background Technology

[0002] PTA is a major raw material for the production of polyester fibers, resins, films, and container resins. It is widely used in the fields of chemical fiber, container, packaging, and film production. In the past few years, the PTA process has developed rapidly, and the rotary pressure filter technology that emerged with it has also developed rapidly. The use of this unit has greatly simplified and shortened the process of PTA plant. PTA is a major raw material for the production of polyester fibers, resins, films, and container resins. It is widely used in the fields of chemical fiber, container, packaging, and film production.

[0003] Over the past few years, the PTA process has developed rapidly, and the rotary pressure filter technology that emerged with it has also developed rapidly. The use of this unit has greatly simplified and shortened the process of PTA plant, and greatly reduced the energy consumption of the plant. It is a revolutionary innovation of traditional technology. In recent years, rotary pressure filters have also been widely used in pharmaceutical and other chemical industries.

[0004] The isolation unit is a crucial component of a rotary pressure filter. Its sealing layer tightly adheres to the outer surface of the filter drum, dividing the filter into multiple independent functional areas to achieve different functions. After a period of operation, the equipment requires maintenance and replacement of vulnerable parts. The two isolation units located at the bottom of the equipment present significant difficulties during disassembly due to their tight contact with the filter press frame and lack of leverage. Reassembly also presents challenges due to limited operating space and the relatively large weight of the isolation units, requiring manual disassembly and reassembly by on-site personnel. This increases both the workload and safety risks for the workers. Summary of the Invention

[0069] Simultaneously adjust the handwheels of the two lifting machines so that the filter press isolation unit is sent into the appropriate position in the filter press isolation unit cavity, and the filter press isolation unit installation is completed;

[0070] The disassembly process is as follows:

[0071] At the same time, an upward force is applied to the two handles 14 of the two tooling parts 1 from both ends, causing them to rotate around the shaft pin 2. The angle is adjusted so that the flange heads of the two lifting machines are facing the filter press isolation unit 3. At this time, the fixed elongated hole 112 of the two bending plates 11 corresponds to the pin hole on the frame end flange. The two tooling parts 1 are fixed to the frame end flange of the filter press isolation unit 3 through the shaft pin 2.

[0072] Adjust the handwheel of the second lifting platform 12 until the flange head of the lifting platform contacts and connects with the outer surface of the filter press isolation unit 3, then rotate the handwheel of the lifting platform.

[0073] Pull out the isolation unit fixed in the isolation unit cavity, then pull out the shaft pin in the fixed elongated hole 112 in sequence, lean the two tooling parts 1 against the filter press frame, adjust the handwheel, lower the filter press isolation unit 3 to the surface of the bending plate 11, loosen the fasteners connecting the isolation unit and the lifting flange head, slide the removed isolation unit down from the guide rail, place it in a suitable position, remove the tooling, and the isolation unit disassembly is completed.

[0074] Specifically, in this embodiment, the outer surface of the isolation unit has threaded holes that match the flange head of the elevator; the flange heads of the left and right elevators are simultaneously adjusted by handwheels to be flush with the upper surface of the L-shaped curved plate base; the isolation unit is pushed to the upper flange head of the left and right parts by the L-shaped sliding guide rail, and temporarily fixed to the tooling by bolts.

[0075] Simultaneously apply an upward force to the handles on both the left and right sides to rotate them around the pivot pin, adjusting the angle so that the isolation unit is precisely aligned with the filter press isolation unit cavity, as shown in the attached diagram. Figure 1 and attached Figure 2 As shown, at this time, the fixed elongated holes on the left and right curved plates are exactly in line with the corresponding (original or specially machined) pin holes on the end flange of the filter press.

Then, fix and remove the tooling by the previous method, and the isolation unit installation is completed.

[0076] At the same time, apply an upward force to the handles of the left and right parts to make them rotate around the shaft pin. Adjust the angle so that the flange heads of the left and right parts are exactly aligned with the filter press isolation unit. At this time, the fixed elongated holes on the left and right parts are exactly the corresponding (original or specially machined) pin holes on the end flange of the filter press. The left and right parts are fixed to the end flange respectively by the shaft pin.

[0077] Adjust the handwheels of the lifting mechanisms on the left and right sides so that the flange head contacts the outer surface of the isolation unit and is connected with bolts. Then, rotate the lifting mechanism handwheel to slowly pull out the isolation unit fixed in the isolation unit cavity. Next, pull out the shaft pins in the oblong holes on both sides in sequence. Control the two handles to rotate around the pin shaft and slowly lean the fixture against the filter press frame. Adjust the handwheel to lower the isolation unit to the surface of the curved plate. Loosen the fasteners connecting the isolation unit and the flange head, slide the removed isolation unit off the guide rail, and place it in a suitable position. Remove the fixture; the disassembly of the isolation unit is complete.

The left (right) part consists of a bent plate, a lifting mechanism, a lifting mechanism base, and a handle. A certain position on one side of the lower surface of the bent plate is connected to the lifting mechanism base. The lifting mechanism base and the lifting mechanism are fixed with bolts. The bent plate has an L-shaped cross-section, and its specific length depends on the structure of the filter press. The bent plate has a circular hole slightly larger than the lifting mechanism flange head, which facilitates the connection between the lifting mechanism flange head and the isolation unit through the bent plate. The bent plate has a pin hole on the side plate on the same side as the lifting mechanism base, and one or more fixed elongated holes are opened at a certain distance from the pin hole. A handle is fixed on the other side of the bent plate. The two end flanges of the filter press to which the isolation unit is to be disassembled or installed have pin holes (original or specially machined) corresponding to the pin holes and fixed elongated holes on the bent plate.
