Description

Technical Field

[0001] The utility model relates to the technical field of disc filters, in particular to a tool for hoisting a filter element of a disc filter. Background Art

[0002] Bisphenol A and diphenyl carbonate form polycarbonate through transesterification and polycondensation reactions. In a polycarbonate plant, these reactions are all carried out in a high-temperature melt state. The polycarbonate melt formed by the reaction contains some impurities such as overreacted and residual carbides. High-end polycarbonate products usually need to remove these impurities. Generally, the measure taken is to pass the melt through a special disc filter to block these impurities. The disc filter is generally cylindrical, with a head at each end, and there is a filter element inside. The filter element has a plurality of disc-shaped filter elements similar to discs. The bottom of the filter element is a large solid ring, the top is a solid conical flange with a lifting ring, and there are multiple disc groups in the middle.

[0003] Since the filter element needs to be inverted up and down multiple times during the cleaning process, when the solid conical flange with a lifting ring is placed downward, the discs in the top area will contact the ground and be stressed, and it is easy to occur phenomena such as disc deformation and damage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tool for hoisting a filter element of a disc filter in order to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A tool for hoisting a filter element of a disc filter includes a circular base. One end of the circular base is fixedly connected with a disc group. The inner wall of the disc group is fixedly connected with a filter element. One end of the disc group is fixedly connected with a conical flange. The top of the conical flange is fixedly connected with a lifting ring. A connecting ring is arranged on the inner wall of the lifting ring, and a special hoisting component for preventing the disc group from being damaged during hoisting is installed on the connecting ring.

[0007] Preferably, the special hoisting component includes a fixing ring for supporting the connecting ring. A supporting rod for supporting the fixing ring is fixedly connected to the inner wall of the fixing ring. A hoisting ring for fixing a hoisting hook is fixedly connected to the outer wall of the fixing ring. A supporting seat for fixing the supporting rod is fixedly connected to the bottom of the supporting rod.

[0008] Preferably, the two sides of the supporting seat are triangular in shape, and the two sides of the supporting seat are formed by welding three angle steels.

[0009] Preferably, the structure of the supporting rod is a hollow tube.

[0010] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0011] In this application, the staff first installs the lifting ring on the disc filter onto the connecting ring, and then fixes the hook of the lifting mechanism to the lifting ring. In this way, when lifting the disc filter, the top of the disc filter does not directly contact the ground, but one end of the disc filter is suspended through the lifting ring, avoiding the situation where the top of the disc filter directly touches the ground and is damaged.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0018] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0019] Embodiment 1:

[0020] As Figures 1-3 shown, a tool for lifting the filter element of a disc filter includes a circular ring base 1. One end of the circular ring base 1 is fixedly connected to a disc stack 2. The inner wall of the disc stack 2 is fixedly connected to a filter element 3. One end of the disc stack 2 is fixedly connected to a conical flange 4. The top of the conical flange 4 is fixedly connected to a lifting ring. The inner wall of the lifting ring is provided with a connecting ring 5. A special lifting component for preventing damage to the disc stack 2 during lifting is installed on the connecting ring 5.

[0021] Embodiment 2:

[0022] It is basically the same as the technical solution of the first embodiment, except that, as Figure 3 shown, the special hoisting component includes a fixing ring 6 for supporting the connecting ring 5. The inner wall of the fixing ring 6 is fixedly connected with a supporting rod 7 for supporting the fixing ring 6. The outer wall of the fixing ring 6 is fixedly connected with a hoisting ring 8 for fixing the hoisting hook. The bottom of the supporting rod 7 is fixedly connected with a supporting seat 9 for fixing the supporting rod 7. The two sides of the supporting seat 9 are triangular in shape. The two sides of the supporting seat 9 are formed by welding three angle steels. The supporting seat 9 is welded by angle steels with a side width of 50 mm, a wall thickness of 5 mm, and a carbon steel material.
