At this time, the connecting positioning plate 5 is stuck at the side end of the first positioning block 6, and the connecting plate 7 is placed on one side of the connecting positioning plate 5. The connecting positioning plate 5 is connected and fixed by passing the positioning bolt 8 through the connecting plate 7. The position of the connecting positioning plate 5 is fixed by multiple groups of positioning bolts 8. Multiple groups of first positioning blocks 6 and positioning bolts 8 are provided inside the housing 1, which can fixedly install the impeller assembly housing 3 inside the housing 1 and reduce the situation that the impeller assembly housing 3 is prone to looseness after long-term work.

[0023] After the connecting positioning plate 5 is installed to the side end of the No. 1 positioning block 6, the connecting positioning plate 5 will be on one side of the No. 2 positioning block 9, align the positioning rod 10 with one side of the connecting positioning plate 5, rotate the positioning rod 10 to insert it into the interior of the connecting positioning plate 5, and the positioning rod 10 can improve the position fixing stability of the connecting positioning plate 5, thereby reducing the impact of vibration on the impeller assembly shell 3.

[0024] The reinforcement unit includes a reinforcement rod 11; the reinforcement rod 11 is fixedly connected to the side end of the connection positioning plate 5; the side end of the reinforcement rod 11 is rotatably connected to a connecting nut 12; the side end of the positioning base 4 is fixedly connected to a connecting rod 13, and the connecting rod 13 is connected to the connecting nut 12.

[0025] After the connecting positioning plate 5 is placed on the side end of the No. 1 positioning block 6, first align the connecting nut 12 with the connecting rod 13. The connecting nut 12 and the connecting rod 13 can be threadedly connected.

The positioning bolt 8 can improve the fixity of the position of the connecting positioning plate 5.

[0026] The outer side walls of the positioning bolt 8 and the positioning rod 10 are coated with anti-loosening thread fixing agent.

[0027] The positioning bolts 8 and the positioning rods 10 need to be coated with anti-loosening thread fixing agent before working. Anti-loosening thread fixing agent is a special chemical material used to prevent threaded connections from loosening under vibration, impact or other mechanical stresses. It usually appears in the form of an adhesive and can effectively improve the stability and reliability of the threaded connection, thereby reducing the impact of vibration on the impeller assembly shell 3.

The limit plate 16 can be rotated by rotating the rotating rod 15 to be stuck to the side end of the partition plate 14. The position of the partition plate 14 is limited by multiple sets of limit plates 16. When the partition plate 14 needs to be maintained and cleaned, the limit plate 16 can be rotated.

[0030] A magnet sheet is fixedly connected to the inner side wall of the limiting plate 16 , and the magnet sheet corresponds to the partition plate 14 .

[0031] Inside the limit plate 16, there is a magnet sheet. When the limit plate 16 rotates and contacts the partition net plate 14, the magnet sheet will contact the side end of the partition net plate 14, and the partition net plate 14 is adsorbed by the magnetic attraction of the magnet sheet, improving the connection stability between the partition net plate 14 and the housing 1.

[0032] The working principle of the present utility model: Before work, install the impeller assembly housing 3 inside the housing 1. The impeller assembly housing 3 and the connection positioning plate 5 are fixedly connected.

The connection nut 12 and the connecting rod 13 can be threadedly connected. First, rotate the connection nut 12 to connect with the connecting rod 13, thereby fixing and strengthening the positions of the rod 11 and the connecting rod 13, and further defining the positional relationship between the connection positioning plate 5 and the positioning base 4. Cooperating with the positioning bolt 8 can improve the fixing of the position of the connection positioning plate 5; after the connection positioning plate 5 is installed at the side end of the first positioning block 6, at this time, the connection positioning plate 5 will be on one side of the second positioning block 9. Align the positioning rod 10 with one side of the connection positioning plate 5 and rotate the positioning rod 10 to insert it into the connection positioning plate 5. The position fixing stability of the connection positioning plate 5 can be improved through the positioning rod 10, and further reduce the influence of vibration on the impeller assembly housing 3; the positioning bolt 8 and the positioning rod 10 need to be coated with anti-loosening thread fixing agent before work. The anti-loosening thread fixing agent is a special chemical material used to prevent the threaded connection from loosening under the action of vibration, impact or other mechanical stresses. It usually appears in the form of an adhesive, which can effectively improve the stability and reliability of the threaded connection, thereby reducing the influence of vibration on the impeller assembly housing 3; before work, the partition net plate 14 can be installed at the side end of the housing 1.

By rotating the rotating rod 15, the limit plate 16 can be clamped to the side end of the partition net plate 14, and the position of the partition net plate 14 is limited by multiple groups of limit plates 16. When the partition net plate 14 needs to be maintained and cleaned, just rotate the limit plate 16; inside the limit plate 16, there is a magnet sheet. When the limit plate 16 rotates and contacts the partition net plate 14, the magnet sheet will contact the side end of the partition net plate 14, and the partition net plate 14 is adsorbed by the magnetic attraction of the magnet sheet, improving the connection stability between the partition net plate 14 and the housing 1.
