[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides the following technical solution:

[0018] Example 1: A wastewater recycling drainage system for a catering cart includes a water collection tank 1 and two water collection rods 2. Multiple cylinder covers 3 are fixedly connected to the bottom of the top water collection rod 2, and multiple cylinders 4 are fixedly connected to the top of the bottom water collection rod 2. Each cylinder 4 contains a filter element 5. A water pump 6 is fixedly installed on one side of the water collection tank 1, and a locking mechanism 7 is provided on the other side of the water collection tank 1. The locking mechanism 7 includes a rotating rod 71 and a support plate 72. A limit gear 73 is fixedly connected to the rotating rod 71, and a lifting rod 74 is slidably connected to the support plate 72. A toothed block 75 is fixedly connected to the top of the lifting rod 74, and a spring 76 is fixedly connected to the bottom of the toothed block 75 at the position corresponding to the lifting rod 74. A guide rod 77 is fixedly connected to one end of the rotating rod 71, and a guide block 78 is slidably connected inside the guide rod 77.

[0019] The conveying pipe of the bottom water collecting rod 2 is fixedly connected to and passes through the side wall of the water collecting tank 1. The top water collecting rod 2 passes through multiple cylinder covers 3. The bottom water collecting rod 2 passes through multiple cylinders 4. The bottom water collecting rod 2 is fixedly connected to the side wall of the water collecting tank 1. The cylinder covers 3 are all slidably connected to the top of the cylinders 4. Sealing gaskets are provided at the opposite positions of the cylinder covers 3 and cylinders 4. The bottom water inlet of the water pump 6 is fixedly connected to and passes through the side wall of the water collecting tank 1. The rotating rod 71 is rotatably connected to the side wall of the water collecting tank 1 at the position corresponding to the top of the bottom water collecting rod 2. The support plate 72 is fixedly connected to the side wall of the water collecting tank 1 at the position corresponding to the bottom of the rotating rod 71. One end of the guide block 78 is rotatably connected to the side wall of the top water collecting rod 2. The bottom end of the spring 76 is fixedly connected to the top of the support plate 72. The limiting gear 73 is meshed with the tooth block 75.

[0020] In use, the top water collection rod 2 is connected to the flexible conveying pipe of the dining car's handwashing sink. The wastewater from the handwashing sink undergoes a first layer of filtration through the filter screen inside the sink. After being sent to the top water collection rod 2 through the flexible pipe, the water then passes through the cylinder cover 3 and into the cylinder body 4. It is then filtered by the filter element 5 inside the cylinder body 4 and finally conveyed to the water collection tank 1 through the bottom water collection rod 2. When the water collection tank 1 is full, the purified water inside the water collection tank 1 can be pumped out by the water pump 6 for reuse. When the filter element 5 needs to be replaced, first directly lift the guide rod 77 upwards. When the guide rod 77 rotates upward, it drives the rotating rod 71 and the limiting gear 73 to rotate. The rotation of the limiting gear 73 compresses the toothed block 75, causing the toothed block 75 to move the lifting rod 74 downward. At the same time, the toothed block 75 also compresses and contracts the spring 76. During the rotation of the limiting gear 73, the toothed block 75 will repeatedly bounce up and down through the spring 76 until the guide rod 77 rotates upward by 90°. At this point, the connection between the limiting gear 73 and the toothed block 75 can limit the rotation rod 71 and the guide rod 77. Figure 4Then, the top water collecting rod 2 is moved upwards. The top water collecting rod 2 will drive multiple cylinder covers 3 to move upwards simultaneously and separate from the cylinder body 4. At the same time, the top water collecting rod 2 will also drive the guide block 78 to slide inside the guide rod 77. At this time, the filter element 5 inside the cylinder body 4 can be pulled out and a new filter element 5 can be placed. Then, the top water collecting rod 2 is reset. The water collecting rod 2 will drive the cylinder cover 3 to connect with the cylinder body 4. The sealing gasket between the cylinder body 4 and the cylinder cover 3 can prevent water leakage at the connection between the two. Then, the guide rod 77 is reset. When the guide rod 77 is no longer vertical, the top water collecting rod 2 cannot move back and forth due to the connection between the cylinder cover 3 and the cylinder body 4. Only when the guide rod 77 rotates vertically upwards can the top water collecting rod 2 move. The whole operation process is very simple. It can not only effectively speed up the replacement efficiency of the filter element 5 and reduce the time spent on the replacement process, but also greatly reduce the energy consumption of the staff, making the maintenance operation easier and more efficient, and indirectly providing a guarantee for the continuous operation of the catering car.

[0021] Example 2: The technical solution that differs from Example 1 in this example includes: a cover plate 8 is slidably connected to the water collection tank 1, and a handle 9 is fixedly connected to the top of the cover plate 8;

[0022] When cleaning the inside of the water collection tank 1, you can slide the cover plate 8 away from the water collection tank 1 using the handle 9. After removing the cover plate 8, you can clean the inside of the water collection tank 1.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
