[0002] Ship is a general term for various vessels. Ship is a means of transportation that can sail or anchor in waters for transportation or operations, and has different technical performance, equipment and structural types according to different usage requirements.

[0003] Ships are man-made vehicles that mainly operate in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats. They are generally called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that uses external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly updated with the advancement of science and technology. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly steel, aluminum, fiberglass, acrylic and various composite materials.

[0034] like Figure 1-2 As shown:

[0035] The detachable ship stern pipe cement sand purification device comprises a purification chamber 1, which is hollow and cylindrical. A water inlet 2 and a water outlet 3 are respectively arranged on the upper side of the purification chamber 1, and a sewage outlet 4 is arranged at the lower part of the purification chamber 1.

[0036] The water inlet 2 is located above the water outlet 3 , and an upper baffle 8 for sealing and isolation is provided between the water inlet 2 and the water outlet 3 .

[0037] The water inlet 2 and the purification chamber 1 are designed to be tangentially eccentric. After the water enters the purification chamber 1 from the water inlet 2, a vortex is generated. A detachable hollow tubular vortex chamber 5 is provided in the middle of the purification chamber 1, and an openable cover plate 6 is provided on the top of the purification chamber 1. The cover plate 6 and the purification chamber 1 are opened by multiple bolts.

[0038] The top of the swirl chamber 5 is in contact with the inner side of the cover plate 6, and an inner water inlet 7 is provided at the upper part of the swirl chamber 5 at a position corresponding to the water inlet 2. The side of the swirl chamber 5 is a sealed tube body, and the bottom of the swirl chamber 5 is a communicable opening.

[0039] Preferably, a fixed tube 9 that can be inserted into the cyclone chamber 5 is fixedly provided in the center of the purification chamber 1, the top of the fixed tube 9 is sealed with the upper baffle 8, the side of the fixed tube 9 is a sealed tube body, and the bottom of the fixed tube 9 is a communicable opening.

[0040] A porous lower baffle 10 is provided between the lower portion of the cyclone chamber 5 and the purification chamber 1 .

[0041] The inner side surface of the purification chamber 1 above the upper baffle plate 8 is evenly provided with a wear-resistant layer. The wear-resistant layer is sprayed with wear-resistant and corrosion-resistant materials.

[0042] The inner water inlet 7 is located at the upper part of the upper baffle 8, and the inner water inlet 7 is composed of a plurality of evenly distributed through holes.

[0043] The through hole and the cyclone chamber 5 are designed to be tangentially eccentric, and a cyclone is generated after the water enters the cyclone chamber 5 through the through hole.

[0044] The main swirl structure of the device is made of erosion-resistant and corrosion-resistant composite material, or the surface is sprayed with wear-resistant and corrosion-resistant coating, which increases the service life.

[0045] Turbid water containing sediment is injected into the upper chamber above the upper baffle 8 from the water inlet 2 located at the upper side of the device. The water inlet 2 is tangentially eccentrically designed to allow the water to undergo a preliminary vortex in the upper chamber.

[0046] Then the water enters the cyclone chamber 5 from several tangential eccentric through holes at the upper end of the cyclone chamber 5 and generates a high-speed vortex. Under the action of the vortex, the solid sediment particles are deposited along the inner wall of the cyclone chamber 5 to the bottom of the purification chamber 1. Under the action of the cyclone, the free upward movement of the particles is suppressed and they are always in a sedimentation state.

[0047] Clean water with low particle content is discharged upward from the passage between the purification chamber 1 and the cyclone chamber 5 to the water outlet 3 .

[0051] The inner side of the purification chamber 1 above the upper baffle plate 8 is evenly provided with a wear-resistant layer. The purification chamber 1 above the upper baffle plate 8 is more easily worn when viewed from above. The openable cover plate 6 facilitates the coating of the wear-resistant layer on the purification chamber 1 above the upper baffle plate 8, thereby increasing the service life of the purification device.

[0052] A porous lower baffle 10 is provided between the lower part of the cyclone chamber 5 and the purification chamber 1, and clean water can pass through the lower baffle 10. As for impurities, the lower baffle 10 combined with the vortex effect can effectively prevent the impurities from moving upward, thereby improving the purification efficiency of the device.
