[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0033] A water-saving leather spraying machine includes a bottom plate 1. Support columns 2 are fixedly connected to the four corners at the lower end of the bottom plate 1. A first connection frame 3 and a second connection frame 4 are fixedly connected to the front part and the rear part at the upper end of the bottom plate 1 together.

A plurality of second connecting pipes 67 are fixedly connected through insertion to the lower side of the outer surface of the first connecting pipe 66. Nozzles 68 are provided on the lower sides of the outer surfaces of the plurality of second connecting pipes 67. A plurality of snap rings 69 are clamped on the outer surface of the first connecting pipe 66. The lower end of the water tank 61 is fixedly connected to the front part of the upper end of the connection plate 5. The rear end of the pressure pump 65 is fixedly connected to the front end of the first connection frame 3. The upper ends of the plurality of snap rings 69 are fixedly connected to the lower inner wall surface of the first connection frame 3. The first connecting pipe 66 is clamped to the lower inner wall surface of the first connection frame 3 through the plurality of snap rings 69.
[0035] Through the above solution: First, inject the liquid required for spraying into the water tank through the water injection port 62 at the upper right part of the water tank 61. Start the water pump 63 installed in the middle of the upper end of the water tank 61 to pump out the liquid in the water tank and convey it upward to the first delivery pipe 64. The liquid flows in the first delivery pipe 64, and the pressure pump 65 provided on the outer surface applies pressure to the liquid to ensure that the liquid has sufficient spraying power. The pressurized liquid enters the first connecting pipe 66 from the end of the first delivery pipe 64 far from the water pump 63, and then is divided and flows into a plurality of second connecting pipes 67 fixedly connected through insertion to the lower side of the outer surface of the first connecting pipe 66.

The first connecting pipe 66 is clamped to the lower inner wall surface of the first connection frame 3 through a plurality of snap rings 69 fixedly connected to the lower inner wall surface of the first connection frame 3, which plays a role in fixing and supporting the first connecting pipe 66 and ensures its stability during the working process. At the same time, the rear end of the pressure pump 65 is fixedly connected to the front end of the first connection frame 3, which also ensures the stable installation of the pressure pump.
[0036] In this embodiment, the recovery device 7 includes a slurry recovery tank 71. The lower end of the slurry recovery tank 71 is fixedly connected through insertion with a connecting frame 72. The lower end of the connecting frame 72 is fixedly connected through insertion with a filtering component 73. The left part of the front end of the filtering component 73 is provided with a second delivery pipe 74. The lower end of the slurry recovery tank 71 is fixedly connected to the middle part of the upper end of the bottom plate 1. One end of the second delivery pipe 74 far from the filtering component 73 is fixedly connected through insertion with a water tank 61. The filtering component 73 includes a filtering frame 731, a coarse filter screen 732, a fine filter screen 733 and a delicate filter screen 734. The coarse filter screen 732 is installed in the upper inner part of the filtering frame 731. The fine filter screen 733 is installed below the coarse filter screen 732 and in the middle inner part of the filtering frame 731. The delicate filter screen 734 is installed below the fine filter screen 733 and in the lower inner part of the filtering frame 731. The aperture of the coarse filter screen 732 is larger than that of the fine filter screen 733, and the aperture of the fine filter screen 733 is larger than that of the delicate filter screen 734. The coarse filter screen 732, the fine filter screen 733 and the delicate filter screen 734 are detachably installed in the filtering frame 731.
[0037] Through the above solution: During the slurry spraying operation, the slurry that has not adhered to the leather falls into the slurry recovery tank 71. Under the action of gravity, the slurry enters the filtering component 73 through the connecting frame 72 fixedly connected through insertion at the lower end. After entering the filtering frame 731, it first passes through the coarse filter screen 732 located in the upper inner part, and larger particles of impurities are intercepted. Then, the slurry preliminarily filtered by the coarse filter screen 732 continues to flow downward and reaches the fine filter screen 733 located in the middle inner part, and smaller impurities are further filtered. Next, the slurry flows to the delicate filter screen 734 located in the lower inner part, and extremely fine impurities are removed, thereby obtaining relatively pure slurry. The filtered pure slurry is conveyed out through the second delivery pipe 74 provided at the left part of the front end of the filtering component 73. Since one end of the second delivery pipe 74 far from the filtering component 73 is fixedly connected through insertion with the water tank 61, the pure slurry finally flows back to the water tank 61 for reuse in the slurry spraying operation. Moreover, the coarse filter screen 732, the fine filter screen 733 and the delicate filter screen 734 are detachably installed in the filtering frame 731, which facilitates regular disassembly for cleaning or replacement to ensure the filtering effect.
[0038] It should be noted that the present utility model is a water-saving leather spraying machine. During the use process, first, liquid for spraying is injected into the water tank 61 through the water injection port 62. The water pump 63 is started to pump out the liquid in the water tank 61. After passing through the first delivery pipe 64, the pressure is increased under the action of the pressure pump 65 to ensure that the liquid can be sprayed smoothly. The liquid then enters the first connecting pipe 66 and the second connecting pipe 67, and finally sprays out from the spray head 68 to complete the leather spraying operation. During the spraying process, the slurry that is not attached to the leather falls into the slurry recovery tank 71, and then enters the filtering assembly 73 through the connecting frame 72. In the filtering frame 731, the slurry is successively filtered layer by layer through a coarse filter screen 732, a fine filter screen 733, and a fine filter screen 734 with gradually decreasing pore sizes to remove impurities. The filtered slurry returns to the water tank 61 through the second delivery pipe 74 to achieve the recycling and reuse of the slurry.
