DETAILED DESCRIPTION

[0015] A mechanical seal that is convenient for cooling and cleaning, comprising a shaft sleeve 1, a flange 4 sleeved on the outer wall of the shaft sleeve, a mechanical sealing mechanism 2 installed between the shaft sleeve and the flange, and a cooling and cleaning mechanism. The flange is provided with a horizontal cooling water inlet 3 connected to the mechanical sealing mechanism, a horizontal cooling water outlet 15, a vertical water inlet 5 connected to the horizontal cooling water inlet, and a vertical water outlet 13 connected to the horizontal cooling water outlet. The upper parts of the vertical water inlet and the vertical water outlet are both provided with internal threads. The cooling and cleaning mechanism includes Water inlet bolt 9, water inlet joint 8, water outlet bolt 11 and water outlet joint 12, the water inlet bolt is installed at the vertical water inlet hole, the water outlet bolt is installed at the vertical water outlet hole, the water inlet bolt and the water outlet bolt both include a bolt cap and a bolt rod, and the bolt rod is respectively provided with horizontal multi-through holes 7 and vertical bolt holes 6, the horizontal multi-through holes extend to the outer wall of the screw rod, and the vertical bolt holes extend to the bottom end of the screw rod, the water inlet joint is installed at the horizontal multi-through holes of the water inlet bolt, and the water outlet joint is installed at the horizontal multi-through holes of the water outlet bolt.

[0016] Furthermore, bolt plugs 10 are mounted on the horizontal multi-through holes where no joints are installed.

[0017] Furthermore, the horizontal cooling water inlet and the horizontal cooling water outlet are both through holes, and flange plugs 14 are installed at the outer ends.

[0018] Furthermore, the horizontal cooling water inlet and the horizontal cooling water outlet are both blind holes.

[0019] Furthermore, the water inlet joint and the water outlet joint are both rotary joints that can be rotated to any angle, making installation and angle adjustment more convenient.

[0020] The mechanical sealing mechanism is prior art.

[0021] The present invention protects a mechanical seal that is easy to cool and clean. Cooling water flows from the water inlet joint through the horizontal multi-holes of the water inlet bolts into the vertical bolt holes, then into the vertical water inlet holes of the flange. Then, it flows through the horizontal cooling water inlet to the mechanical seal mechanism for cooling and flushing. Then, it flows from the horizontal cooling water outlet through the vertical water outlet holes into the vertical bolt holes of the water outlet bolts, then flows through the horizontal multi-holes into the water outlet joint and into the circulating cooling system. This cools and cleans the mechanical seal mechanism, preventing the mechanical seal mechanism from operating at high temperatures for a long time, which may cause a loose seal. Impurities can also be removed in a timely manner, ensuring the operating effect of the mechanical seal and extending the service life of the equipment.

[0022] At the same time, since the water inlet bolt and the water outlet bolt are respectively provided with multiple interconnected horizontal multi-through holes and a vertical bolt hole inside the bolt rod, the horizontal multi-through holes extend to the outer wall of the screw rod, and the vertical bolt hole extends to the bottom end of the screw rod, the water inlet rotary joint is installed at the horizontal multi-through holes of the water inlet bolt, and the water outlet rotary joint is installed at the horizontal multi-through holes of the water outlet bolt. The water inlet rotary joint and the water outlet rotary joint can be connected to any horizontal multi-through holes as needed, and the bolts can be rotated to further adjust the installation angle and height. The installation is very convenient and quick, and the angle and height can be adjusted as needed, which is not affected by the liquid connection position of the frame, and multi-directional liquid connection can be achieved.

[0023] In summary, the mechanical seal that is easy to cool and clean protected by the present invention is easy and quick to install, can be adjusted in angle and height, is not affected by the liquid connection position of the frame, and can achieve multi-directional liquid connection.

[0024] It will be apparent to those skilled in the art that the present invention may be subject to various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
