[0025] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1 to 7 As shown, a ship wastewater treatment device includes: a tank 1 and a filter plate structure;

[0027] The top of the housing 1 is open; the filter plate structure includes two symmetrically arranged vertical plates 2, and a number of filter screen plates 3 are connected in sequence along the vertical direction between the two vertical plates 2. The filter screen plates 3 are arc-shaped. A top plate 4 is connected between the top sides of the two vertical plates 2. A water inlet 41 is provided in the middle of the top plate 4. A hanging plate 5 with an inverted U-shaped cross section is symmetrically connected to the vertical plates 2. One end of the hanging plate 5 is located outside the housing 1, and the other end is located inside the housing 1 and is fixedly connected to the top surface of the vertical plate 2. A column 11 is provided on the housing 1 to fix the hanging plate 5.

[0028] Specifically, the vertical plate 2 contacts the inner wall of the housing 1, and the filter screen plate 3 and the top plate 4 also contact the inner wall of the housing 1 on both sides. Wastewater enters from the inlet 41, passes through the arc-shaped filter screen plate 3 in sequence, and then settles at the bottom of the housing 1. The hanging plate 5 with an inverted U-shaped cross section cooperates with the housing plate of the housing 1, and the vertical plate 2 is fixedly connected to the hanging plate 5. When the column 11 is not fixed to the hanging plate 5, the hanging plate 5 can be lifted upwards, thereby lifting the vertical plate 2 together with the filter screen plate 3. The filter plate structure can be disassembled to clean the filter screen plate 3 and improve the filtration efficiency.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the upright column 11 is vertically fixed to the housing 1. The hanging plate 5 has a through hole for the upright column 11 to pass through, and also includes a screw rod. The top end of the screw rod is connected to a stop bar 12, and the top of the upright column 11 has a screw hole that mates with the screw rod. When the screw rod is threaded onto the upright column 11, the stop bar 12 can restrict the hanging plate 5 to prevent it from being dislodged from the upright column 11 by external forces such as vibration. Furthermore, to ensure reliability, two upright columns 11 are provided on each side.

[0030] Furthermore, the mesh diameter of the filter plates 3 decreases sequentially from top to bottom. This allows for the filtration of substances of different sizes, improving the filtration effect.

[0031] Furthermore, the filter screen 3 is connected to an end plate 6 at one end, and the vertical plate 2 is provided with a horizontal slide rail that cooperates with the end plate 6. The end plate 6 is also provided with a fixing block 7 for fixing the end plate 6. The end plate 6 is fixed by the fixing block 7. Specifically, there are two embodiments, such as... Figures 1 to 4 As shown in the first embodiment, one end of the vertical plate 2 is provided with a side groove 21, which communicates with the horizontal slide rail. The fixing block 7 is fixedly connected to the end plate 6 and located within the side groove 21. Screws are also provided to fix the fixing block 7 to the bottom of the side groove 21. A threaded hole is provided at the bottom of the side groove 21. When the screw passes through the fixing block 7 and is threadedly connected to the vertical plate 2, the fixing block 7 is fixed to the vertical plate 2, thereby fixing the end plate 6 to the vertical plate 2. To ensure a secure fixation, each end plate 6 is fixed with two fixing blocks 7. Figures 5 to 7 As shown in the second embodiment, a sliding groove is provided on the middle of the end plate 6. The fixing block 7 is slidably disposed in the sliding groove in the vertical direction. A spring 8 is connected between the fixing block 7 and the bottom of the sliding groove. A sliding groove 22 is provided on the vertical plate 2, into which the fixing block 7 can extend. The sliding groove 22 is connected to the horizontal slide rail. During installation, the end plate 6 slides along the horizontal slide rail. Due to the restriction of the horizontal slide rail, the fixing block 7 is located in the sliding groove, and the spring 8 is compressed. When the sliding plate 6 slides to the position corresponding to the sliding groove 22, the elastic force of the spring 8 causes the fixing block 7 to slide towards the sliding groove 22, thereby making the fixing block 7 engage in the sliding groove 22, thus fixing the end plate 6 to the vertical plate 2.

[0032] Furthermore, such as Figure 1 As shown, a drain pipe 9 is installed in the lower part of the tank 1. After standing and settling for a period of time, the valve of the drain pipe 9 can be opened to discharge the treated wastewater. The valve is not shown in the figure.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
