Description

Technical Field

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1

[0024] from Figure 1-2 As can be seen, an automatic rapid water filtration gate valve of this embodiment includes a valve core 1 and a valve body 7. The valve core 1 is provided inside the valve body 7. An upper perforated plate 11 is provided on the upper part of the valve core 1. Water permeable holes 111 are spaced apart on the surface of the upper perforated plate 11. A water filtration assembly 2 is provided inside the valve cavity of the valve core 1.

[0025] The water filtration assembly 2 includes a main water filtration pipe 22 and branch water filtration pipes 21. The branch water filtration pipes 21 are spaced apart in the cavity of the valve core 1. The branch water filtration pipes 21 have water filtration holes 211 spaced apart on their bodies. The branch water filtration pipes 21 are fitted with filter screens 212. One end of the branch water filtration pipes 21 is connected to the main water filtration pipe 22, and one end of the main water filtration pipe 22 extends to the outside of the valve core 1.

[0026] A side sealing plate 12 is provided on the side of the valve core 1. One end of the water filter main pipe 22 passes through the side sealing plate 12 and is sealed to the side sealing plate 12. The side sealing plate 12 and the valve core 1 are detachably assembled and can be quickly assembled by bolt connection or plug-in connection. When the water filter assembly 2 needs to be repaired, the inside of the valve core 1 can be quickly repaired by removing the side sealing plate 12.

[0027] A reinforcing rib 13 is provided in the middle of the inner side of the valve core 1 to enhance the overall strength of the valve core 1.

[0028] Example 2

[0029] from Figure 1-4 As can be seen, in this embodiment of an automatic rapid water filtration gate valve, a telescopic device 5 is provided in the middle of the valve core 1. The telescopic device 5 drives the valve core 1 to extend and retract within the valve body 7. A contact switch 6 is provided on the displacement path of the valve core 1.

[0030] A solenoid valve 23 is installed at one end of the main water filter pipe 22. A negative pressure resistant hose 3 is connected to one end of the solenoid valve 23. A negative pressure resistant hose 3 is connected to one end of the negative pressure pumping device 4.

[0031] The output terminal of contact switch 6 is electrically connected to solenoid valve 23.

[0032] from Figure 3 As can be seen, in this embodiment, the valve core 1 is made into a hollow gate with a water-permeable hole 111 at the top for water filtration. At the same time, a negative pressure water filtration assembly 2 is manufactured inside it. One end of the water filtration assembly 2 is connected in series with a solenoid valve 23. The solenoid valve 23 is connected to the negative pressure resistant hose 3 and then connected to the negative pressure pumping device 4. When the valve core 1 retracts, the negative pressure resistant hose 3 is in a bent state. When the valve core 1 extends, the negative pressure resistant hose 3 will gradually extend. During the extension process, the negative pressure resistant hose 3 is ensured not to break or flatten.

[0033] When valve core 1 extends, valve body 7 closes. At this time, valve core 1 contacts contact switch 6, solenoid valve 23 receives electrical signal and opens automatically, and pumps out the moisture of the material accumulated at the top. The gate valve is in the state of automatic water filtering and drainage.

[0034] from Figure 4 It can be seen that when the valve core 1 retracts, the valve body 7 opens. At this time, the valve core 1 does not contact the contact switch 6, the solenoid valve 23 closes automatically, and the gate valve is in the open state, which can be used for unloading.

[0035] When the gate valve is closed, this utility model can filter water through the water-permeable hole 111 on the upper part of the valve core 1, which can automatically and quickly reduce the moisture content of the upper part of the gate valve, ensure that the bulk material is discharged in a dry state, eliminate material leakage, and ensure clean production.

[0036] For bulk materials with high moisture content, the moisture flows slowly downwards through the pores of the material under the action of gravity and accumulates at the top of the gate valve. When the gate valve is closed, the moisture enters the cavity of the valve core 1 through the water inlet 111. Then, the water accumulated in the cavity of the valve core 1 is extracted by the negative pressure pumping device 4, the negative pressure resistant hose 3, the main filter pipe 22, and the branch filter pipe 21, thereby effectively reducing the moisture content of the material. When the gate valve is opened later, the bulk material can be discharged in a dry state.

[0037] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
