DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, Figure 1 to Figure 7 The structure of a hydraulic electromagnetic slow-closing mud discharge valve with signal control according to an embodiment of the present invention is schematically shown, and the present invention is further explained below in conjunction with a specific embodiment.

[0025] See also Figure 1-Figure 7 The present invention provides a signal-controlled hydraulic electromagnetic slow-closing mud discharge valve, which includes a valve body 1, two connecting pipes 2 are provided on the side wall of the valve body 1, and both ends of the connecting pipes 2 are respectively connected to the inside of the valve body 1, and also includes an anti-blocking mechanism 3 connected to the connecting pipes 2;

[0026] The anti-blocking mechanism 3 includes a pipe body 31 installed at one end of the connecting pipe 2 through a flange, a filter screen 32 rotatably connected to the inside of the pipe body 31, and a driving part 4 for driving the filter screen 32 to rotate. The filter screen 32 is a cone structure, and the bottom is arranged toward the connecting pipe 2. A fixing ring 33 is provided at the bottom edge of the filter screen 32, and a rotating groove 34 cooperating with the fixing ring 33 is provided on the inner wall of the pipe body 31. A plurality of first slices 35 are provided at one end of the side wall of the filter screen 32 close to the fixing ring 33, and a plurality of second slices 36 cooperating with the first slices 35 are provided on the inner wall of the pipe body 31. The first slices 35 and the second slices 36 are distributed in a circle with the axis of the filter screen 32, and a through hole is formed between two adjacent second slices 36, so that the pipe body 31 is first connected to the sludge discharge pipe of the water pool, so that when the valve stem in the valve body 1 is opened upward, the sludge and filamentous debris in the water pool are first discharged. The filter screen 32 is driven by the driving unit 4 to rotate in the tube body 31, and the fixed ring 33 is prompted to make a circular motion along the rotating groove 34. The mud and sand enter the valve body 1 through the filter holes of the filter screen 32, while the filamentary debris is intercepted by the filter screen 32 and flows toward the inner wall of the tube body 31 along the surface of the filter screen 32 under the thrust of other sludge and the centrifugal effect of the rotation of the filter screen 32, thereby preventing the filamentary debris from being blocked on the surface of the filter screen 32, ensuring that the central part of the filter screen 32 can discharge the sludge normally, and when the filamentary debris enters from the through hole between the second slices 36, the first slice 35 and the second slice 36 form a shear force to cut the filamentary debris into pieces, and the cut filamentary debris enters the valve body 1 through the filter holes of the filter screen 32, thereby preventing the filamentary debris from being entangled on the surface of the valve stem and the valve disc, causing the outlet of the mud discharge valve to be blocked, thereby ensuring the normal operation of the mud discharge valve.

[0027] The driving part 4 includes driving blades 41, and the driving blades 41 are distributed in a circle with the side walls of the filter screen 32. When the fluidity of the sludge in the water pool is relatively large, when the sludge passes through the filter screen 32, the driving blades 41 are prompted to drive the filter screen 32 to rotate, so that when the filamentary debris intercepted by the filter screen 32 enters from the through hole between the second slices 36, the first slice 35 and the second slice 36 form a shear force to cut the filamentary debris into pieces, thereby preventing the filamentary debris from being entangled on the valve stem and the valve disc surface to cause the outlet of the mud discharge valve to be blocked, thereby ensuring the normal operation of the mud discharge valve.

[0028] The driving part 4 includes a plurality of convex teeth 42 extending outward at equal intervals from the edge of the fixing ring 33, the side wall of the tube body 31 is provided with an engagement hole 311 corresponding to the convex teeth 42, the side wall of the tube body 31 is provided with a driving gear 43, the driving gear 43 is engaged with the convex teeth 42 through the engagement hole 311, the side wall of the tube body 31 is provided with a driving motor 44 connected to the driving gear 43, then when the electric signal controls the valve stem to open, the driving motor 44 is started synchronously, and the driving motor 44 drives the driving gear 43 to rotate, so that the driving gear 43 pushes the convex teeth 42 and the fixing ring 33 to rotate in the rotating groove 34, prompting the filter screen 32 to rotate, so that when the filamentary debris intercepted by the filter screen 32 enters from the through hole between the second slices 36, the first slice 35 and the second slice 36 form a shear force to cut the filamentary debris into pieces, thereby preventing the filamentary debris from being entangled on the surface of the valve stem and the valve disc, causing the outlet of the mud discharge valve to be blocked, thereby ensuring the normal operation of the mud discharge valve.

[0029] A limiting protrusion 341 is provided on the inner wall on either side of the rotating groove 34, and a guide rail 331 cooperating with the limiting protrusion 341 is provided on the side wall of the fixing ring 33. When the driving gear 43 pushes the convex tooth 42 and the fixing ring 33 to rotate in the rotating groove 34, the guide rail 331 rotates along the limiting protrusion 341, thereby ensuring that the filter screen 32 maintains stable rotation and preventing the filter screen 32 from deviating and affecting the shearing effect of the first slice 35 and the second slice 36 on the filamentary debris.

[0030] The end of the second slice 36 away from the first slice 35 is a hemispherical structure. When the filamentary debris approaches the second slice 36, it enters along the curved surface of the second slice 36 toward the through hole between the second slices 36 and is cut into pieces by the first slice 35 and the second slice 36 to prevent the filamentary debris from being stuck on the surface of the second slice 36.

[0031] The surfaces of the filter screen 32 and the driving blade 41 are provided with a nano coating, so as to prevent the mud and sand from adhering to the surfaces of the filter screen 32 and the driving blade 41 , thereby ensuring the normal operation of the filter screen 32 and the driving blade 41 .

[0032] The second slice 36 is made of stainless steel and has a heat-conducting wire 361 inside, thereby improving the shearing effect on filamentary debris with strong toughness.

[0033] A sealing filler is provided at the connection between the meshing hole 311 and the convex teeth 42 and the driving gear 43 to improve the sealing performance of the tube body 31 and prevent mud and sand from leaking from the meshing hole 311 .

[0034] A sealing cover 37 is disposed on the outer side of the driving gear 43 to protect the driving gear 43 .

[0035] Embodiment 1: Then, the pipe body 31 is first connected to the sludge discharge pipe of the water pool, so that when the valve stem in the valve body 1 is opened upward, the sludge and filamentary debris in the water pool first flow into the pipe body 31. When the fluidity of the sludge in the water pool is relatively large, when the sludge passes through the filter screen 32, the driving blade 41 drives the filter screen 32 to rotate, and the fixed ring 33 moves in a circle along the rotating groove 34. The silt passes through the filter hole of the filter screen 32 and enters the interior of the valve body 1, while the filamentary debris is intercepted by the filter screen 32 and rotates with the filter screen 32 under the thrust of other sludge. Under the centrifugal action, the filamentary debris flows along the surface of the filter screen 32 toward the inner wall of the tube body 31, thereby preventing the filamentary debris from being blocked on the surface of the filter screen 32, ensuring that the central part of the filter screen 32 can discharge the sludge normally, and when the filamentary debris enters from the through hole between the second slices 36, the first slice 35 and the second slice 36 form a shear force to cut the filamentary debris into pieces, and the cut filamentary debris enters the valve body 1 through the filter holes of the filter screen 32, thereby preventing the filamentary debris from being entangled on the surface of the valve stem and the valve disc, causing the outlet of the mud discharge valve to be blocked, thereby ensuring the normal operation of the mud discharge valve.

[0036] Embodiment 2: When the valve stem in the valve body 1 is opened upward, the drive motor 44 is started synchronously, and the drive motor 44 drives the drive gear 43 to rotate. Therefore, the drive gear 43 pushes the convex tooth 42 and the fixing ring 33 to rotate in the rotating groove 34, and the mud and sand enter the valve body 1 through the filter holes of the filter screen 32, while the filamentary debris is intercepted by the filter screen 32, and flows along the surface of the filter screen 32 toward the inner wall of the tube body 31 under the thrust of other sludge and the centrifugal effect of the rotation of the filter screen 32, thereby preventing the filamentary debris from being blocked on the surface of the filter screen 32, ensuring that the central part of the filter screen 32 can discharge the sludge normally, and when the filamentary debris enters from the through hole between the second slices 36, the first slice 35 and the second slice 36 form a shear force to cut the filamentary debris into pieces, and the cut filamentary debris enters the valve body 1 through the filter holes of the filter screen 32, thereby preventing the filamentary debris from being entangled on the surface of the valve stem and the valve disc, causing the outlet of the mud discharge valve to be blocked, thereby ensuring the normal operation of the mud discharge valve.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and range of equivalent elements of the claims are included in the present invention.
