[0023] Example 1

[0024] Combine Figure 1-Figure 5 A hot-rolled steel cold-sawn medium-pressure water pipe structure includes a pipe seat 1, a medium-pressure pipe 2 and a lateral nozzle 3. The medium-pressure pipe 2 and the lateral nozzle 3 are welded to the outside of the pipe seat 1. Several nozzles 4 are installed on the outside of the medium-pressure pipe 2 and the lateral nozzle 3. A filtering mechanism 5 is installed inside the medium-pressure pipe 2, and a positioning mechanism 6 is installed at the front of the pipe seat 1.

[0025] See Figure 2 and Figure 3 , it is further obtained that the filtering mechanism 5 includes a transfer tube 7, which is welded to the outside of the medium-pressure pipe 2, and the rear end of the transfer tube 7 is used to connect the water pipe 8. The transfer tube 7 and the water pipe 8 are connected by a flange 9. A flow groove 10 is opened inside the transfer tube 7, and a filter cartridge 11 is inserted into the flow groove 10. A sealing cover 12 is fixedly installed at the front end of the filter cartridge 11.

[0026] The installation directions of the medium-pressure pipe 2 and the lateral nozzle 3 are perpendicular to each other. The medium-pressure pipe 2 and the interior of the adapter pipe 7 are interconnected. The pipe seat 1 is fixed in a designated position. The water pipe 8 is the input water pipe for medium-pressure water. The adapter pipe 7 is connected and fixed to the water pipe 8 through a flange 9.

[0027] The diameter of the filter cartridge 11 is smaller than that of the circulation slot 10 , and the rear end of the filter cartridge 11 is engaged with the rear end of the circulation slot 10 . The filter cartridge 11 is used to collect impurities in the medium-pressure water and reduce the blockage of the nozzle 4 .

[0028] The sealing cover 12 is sleeved on the front end of the transfer tube 7 and is threadedly connected. The front end of the medium-pressure pipe 2 is sealed by the sealing cover 12, which facilitates the disassembly and assembly of the filter cartridge 11.

[0029] Specifically, the medium-pressure water enters the medium-pressure pipe 2 and the lateral nozzle 3, and is sprayed out through the nozzle 4 to cool the saw blade and the side of the saw blade. When the medium-pressure water enters the filter cartridge 11, the impurities in the medium-pressure water are filtered through the filter cartridge 11, and the water flows through the circulation groove 10 to reduce the blockage of the nozzle 4. The connection of the sealing cover 12 facilitates the disassembly and cleaning of the filter cartridge 11.

[0030] Example 2

[0031] See Figure 4 and Figure 5 , and on the basis of Example 1, it is further obtained that a limit plate 13 and a limit block 14 are fixedly installed on the outside of the pipe seat 1 near the front end, two limit holes 15 are provided on the front part of the limit plate 13, and the positioning mechanism 6 includes a rotary joint 16, which is movably installed on the front part of the pipe seat 1. The same lateral nozzle 3 and several nozzles 4 are welded to the outside of the rotary joint 16, and a fixed block 17 is fixedly installed on the outside of the rotary joint 16. A positioning rod 18 is movably installed inside the fixed block 17, and a push block 19 is fixedly installed on the outside of the positioning rod 18 near the middle section. A spring 20 is installed on the outside of the positioning rod 18 and inside the fixed block 17.

[0032] The rotary joint 16 is communicated with the interior of the pipe base 1 . The rotary joint 16 is located at the front of the pipe base 1 and is rotatably arranged. The rotary joint 16 drives the corresponding lateral nozzle 3 to rotate for installation and removal of the saw blade.

[0033] The positioning rod 18 is located inside the fixing block 17 and is slidably arranged. The rear end of the positioning rod 18 is engaged with the limiting hole 15. Under the action of the spring 20, the positioning rod 18 slides backward and engages with the limiting hole 15, so that the rotary joint 16 is automatically fixed.

[0034] Specifically, the push block 19 is pushed forward to disengage the positioning rod 18 from the limiting hole 15, and the rotary joint 16 and the corresponding lateral nozzle 3 are rotated to make the lateral nozzle 3 vertical or horizontal. The positioning rod 18 is fixed in the corresponding limiting hole 15 under the action of the spring 20 to facilitate the disassembly and assembly of the saw blade and cooling of both surfaces during operation.

[0035] During actual operation, the output shaft and the pipe seat 1 for mounting the saw blade are fixed at designated locations, and the rear end of the transfer pipe 7 is connected to the water pipe 8 via a flange 9;

[0036] During cooling and filtering, medium-pressure water is delivered to the medium-pressure pipe 2 and the lateral nozzle 3, and is sprayed out through the corresponding nozzle 4 to cool the saw blade and one side of the saw blade. The medium-pressure water enters the filter cartridge 11, and the impurities in the medium-pressure water are filtered by the filter cartridge 11. The filtered medium-pressure water flows through the flow groove 10 to reduce blockage of the nozzle 4. The sealing cover 12 is threadedly connected to the front end of the medium-pressure pipe 2 to facilitate the disassembly and cleaning of the filter cartridge 11.

[0037] When disassembling and assembling the saw blade and cooling the other side, rotate the rotary joint 16 to make the corresponding lateral nozzle 3 in a horizontal state, deliver medium-pressure water to the rotary joint 16 through the pipe seat 1, and cool the other side of the saw blade at the same time through the nozzle 4, push the push block 19 to make the positioning rod 18 slide out of the limiting hole 15, and rotate the rotary joint 16 clockwise through the fixing block 17 to make the corresponding lateral nozzle 3 vertical. The positioning rod 18 is fixed in the limiting hole 15 under the action of the spring 20, and the saw blade is disassembled and assembled.
