[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0028] See also Figure 1-6 The utility model is an environmentally friendly ship sewage negative pressure extraction device, comprising a negative pressure pump 1 and a connecting block 7. The bottom of the negative pressure pump 1 is fixedly connected to a base 2. The right side of the negative pressure pump 1 is connected to a connecting pipe 3. The side of the connecting pipe 3 away from the negative pressure pump 1 is connected to a box body 4. The right side of the top of the box body 4 is connected to a water inlet pipe 5. The inner cavity of the box body 4 is provided with an impurity removal component 6. The impurity removal component 6 includes a box body 601. The connection between the box body 601 and the box body 4 is sealed by a connecting block 7. The top of the box body 601 is fixedly connected to a filter plate 602 by bolts. The left side of the front side of the box body 601 is fixedly connected to a motor 603. The output end of the motor 603 passes through the inner cavity of the box body 601 and is fixedly connected to a stirring rod 604.

[0029] Specifically: when the negative pressure pump 1 is working, the sewage enters the interior of the box body 4 through the water inlet pipe 5, and then the sewage first falls into the box body 601 at the bottom of the filter plate 602. Before the box body 601 is sealed and connected to the box body 4, a flocculant is placed inside it. When the sewage enters the inner cavity of the box body 601, the output end of the motor 603 will drive the stirring rod 604 to rotate, thereby facilitating the mixing of the flocculant and the sewage, and separating some impurities in the sewage from the water. Then the impurities will settle at the bottom of the inner cavity of the box body 601, and the larger impurities in the sewage will accumulate in the depression of the filter plate 602. The filtered sewage will enter the negative pressure pump 1 through the connecting pipe 3, and then the sewage will be discharged by the negative pressure pump 1. After the device has been working for a long time, remove the connecting block 7 at the sealed connection between the box body 601 and the box body 4, and the box body 601 can be taken out, so that the box body 601 and the filter plate 602 can be cleaned. Specific embodiment 2

[0031] See also Figure 1-6 On the basis of the specific embodiment 1, a filter baffle 8 is fixedly connected to the left side of the top of the inner cavity of the box body 4, and the bottom of the filter baffle 8 contacts the filter plate 602. The front and rear sides of both sides of the filter baffle 8 are fixedly connected with triangular plates 9, and the top of the triangular plate 9 is fixedly connected to the inner wall of the box body 4. The bottom of the surface of the connecting pipe 3 is fixedly connected with a filter box 10, the top of the connecting pipe 3 is connected with a pressure gauge 11, and the bottom of the connecting pipe 3 is connected with a valve 12. The rear side of the stirring rod 604 is movably connected to the inner wall of the box body 601 through the bearing seat, and the front side of the surface of the stirring rod 604 is slidably connected with a water lock ring 605. The front side of the water lock ring 605 is fixedly connected to the inner wall of the box body 601. The rear sides of both sides of the motor 603 are fixedly connected with fixed blocks 606, and the rear side of the fixed block 606 is fixedly connected to the box body 601.

[0032] Specifically: by setting the filter baffle 8, the filter baffle 8 can not only limit the filter plate 602 and the box body 601, but also prevent larger impurities from moving to the left side of the inner cavity of the box body 4. By setting the triangular plate 9, the filter baffle 8 is fixed. By setting the filter box 10, the larger impurities in the sewage can be filtered for the second time. By setting the pressure gauge 11 and the valve 12 for use, when the pressure gauge 11 detects that the pressure in the connecting pipe 3 is too high, the staff can relieve the pressure by turning the valve 12, thereby ensuring the stable operation of the device. By setting the water locking ring 605, when the stirring rod 604 rotates, it plays a role in locking water during the normal rotation of the stirring rod 604. By setting the fixing block 606, the motor 603 is fixed.

[0033] The working principle of the present invention is as follows: the sewage inlet pipe is connected to the water inlet pipe 5, and the outlet pipe is connected to the water outlet port of the negative pressure pump 1. When working, the water level of the box body 4 is slightly higher than the filter plate 602, and then the negative pressure pump 1 starts to work. At this time, the sewage enters the interior of the box body 4 through the water inlet pipe 5, and then the sewage first falls into the box body 601 at the bottom of the filter plate 602. Before the box body 601 is sealed and connected to the box body 4, a flocculant is placed inside it. When the sewage enters the inner cavity of the box body 601, the output end of the motor 603 will drive the stirring rod 604 rotates, thereby facilitating the mixing of the flocculant and the sewage, separating some impurities in the sewage from the water, and then the impurities will settle at the bottom of the inner cavity of the box body 601, and the larger impurities in the sewage will accumulate in the depression of the filter plate 602. The filtered sewage will enter the negative pressure pump 1 through the connecting pipe 3, and then the sewage will be discharged by the negative pressure pump 1. When the device has been working for a long time, remove the connecting block 7 at the sealed connection between the box body 601 and the box body 4, and then the box body 601 can be taken out, so that the box body 601 and the filter plate 602 can be cleaned.
