DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0018] according to Figure 1-4 As shown, a vertical hydraulic quick-opening bottom filter and dry residue device includes a filter tank 1, the top of the filter tank 1 is provided with a liquid inlet 2, the bottom is an open structure, the bottom open end is provided with a sealed bottom cover 3, the sealed bottom cover 3 is provided with a sintered plate 4, and a filter screen 5 is detachably installed above the sintered plate 4. The bottom of the sealed bottom cover 3 is connected to the liquid outlet pipe 6, and the liquid outlet pipe 6 is connected to the inner cavity of the filter tank 1. The bottom of the filter tank 1 is provided with a flip assembly, and the flip assembly is used to drive the sealed bottom cover 3 to flip.

[0019] In the above specific technical scheme, the solution to be filtered enters the filter tank 1 through the liquid inlet 2, the liquid passes through the filter screen 5 and the sintered plate 4 and flows out from the liquid outlet pipe 6, and the filter residue remains on the surface of the filter screen 5, realizing solid-liquid separation. Then, air is blown into the filter tank 1 for a certain period of time. By flipping the assembly, the staff can easily remove the filter residue without removing the bolts of the sealing bottom cover 3. In addition, the filter screen 5 can be detachably installed above the sintered plate 4, and the staff can replace the filter screens with different pore sizes as needed, thereby achieving different filtration accuracies of the filter tank 1.

[0020] The liquid outlet pipe 6 is provided with a pneumatic valve 7, and the liquid outlet of the liquid outlet pipe 6 is connected to a water pump through a pipe. The switch of the pneumatic valve 7 can be controlled by a control system or manually operated. After the pneumatic valve of the liquid outlet pipe 6 is opened, the liquid flows out through the liquid outlet pipe 6.

[0021] The turnover assembly includes a rotation force arm 8 arranged at the bottom of the sealed bottom cover 3 , the top of the rotation force arm 8 is hinged to a fixing frame 9 , and the fixing frame 9 is fixedly connected to the filter tank 1 .

[0022] The rotating force arm 8 is connected to the output end of the cylinder 11 through a connecting rod 10 , and the cylinder 11 is fixedly mounted on the outer wall of the filter tank 1 .

[0023] In the above specific technical solution, the cylinder 11 is started, and the piston in the cylinder 11 slides into the cylinder body, thereby driving the rotating force arm 8 to rotate, thereby realizing the rotation of the sealed bottom cover 3, making it easy for the staff to remove the filter cake. When filtering work is required, the piston in the cylinder 11 slides out of the cylinder body, so that the sealed bottom cover 3 covers the open end of the filter tank 1. This design is suitable for the automation of various mechanical equipment and has the characteristics of small size, high performance and good airtightness.

[0024] An annular mounting bracket 12 is provided on the inner wall of the sealed bottom cover 3 , and the sintered plate 4 is embedded in the mounting bracket 12 .

[0025] The upper end surface of the mounting bracket 12 is rotatably mounted with a fixing rod 14 through a pin rod 13, and the lower end surface of the fixing rod 14 abuts against the filter screen. When the staff needs to replace the filter screen 5, the cylinder 11 is started, and the piston in the cylinder 11 slides into the cylinder body. After the sealing bottom cover 3 is rotated, the filter screen 5 is exposed, and the staff rotates the fixing rod 14 to replace the filter screen 5 with the required aperture. Compared with directly fixing the filter screen 5 with bolts, this design reduces damage to the filter screen 5, and replacement does not require disassembly of the bolts, which effectively improves work efficiency.

[0026] The liquid outlet pipe 6 is a metal hose, which is characterized by high flexibility and good elasticity, and will not affect the opening and closing of the sealed bottom cover 3.
