Description

Technical Field

[0001] The utility model belongs to the technical field of slurry gate valves, in particular to a wear-resistant slurry gate valve. Background Art

[0002] Slurry gate valve is mainly used in fluid conveying pipelines with materials in mines and ore dressing plants. It is made of a cast valve body and two flanges welded together, with a carbide sealing surface and a stainless steel gate. It has a reasonable structure, easy operation, quick opening, wear resistance, corrosion resistance, long service life, strong interchangeability, easy assembly, low maintenance cost, high economic benefits, reliable sealing, and avoids the "gnawing" phenomenon. It is suitable for the cut-off of granular material conveying pipelines in mining, metallurgy, coal, chemical industry, power plants and other industries. It is the ideal first choice valve for domestic slurry conveying systems.

[0003] A Chinese patent with publication number CN217328679U discloses a wear-resistant slurry gate valve, and the key points of its technical solution are: it includes a slurry gate valve body, one end of the slurry gate valve body is provided with a support tube, and one end of the support tube is provided with a fixed box; a filter component, the filter component is arranged on the top surface of the fixed box, and is used to filter stones. Through the set filter net, the filter net will block the entry of larger stones in the mud so that the stones enter the interior of the mounting tube. Through the set fixed block, mounting groove and second spring, the fixed block, mounting groove and second spring cooperate with each other to allow the fixed block to enter the interior of the mounting groove. Through the set first spring, fixed ring, connecting column, mounting column, support block and cover plate, the first spring, fixed ring, connecting column, mounting column, support block and cover plate cooperate with each other to allow the cover plate to move downward and the staff can clean the stones on the cover plate to achieve the filtering effect of the slurry gate valve body.

[0004] In the current existing technology, the slurry gate valve is provided with a first spring, a fixed ring, a connecting column, a mounting column, a support block and a cover plate. The first spring, the fixed ring, the connecting column, the mounting column, the support block and the cover plate cooperate with each other, but the mortar pipe is fixedly connected to the filter box. When the mortar flows, it is filtered through the filter box. However, when cleaning the sand and gravel inside the filter box, it is necessary to stop the grouting of the mortar deflector on one end of the mortar pipe. After the mortar inside the pipeline has completely flowed, the filter box is disassembled to clean up the excess sand and gravel inside, and then the mortar pipe is reopened for grouting. The opening and stopping process is relatively slow, and when cleaning the sand and gravel, the filter box needs to be disassembled to clean up the sand and gravel inside. Moreover, the filter box is connected to the grouting pipe through a flange. When the filter box is damaged, it cannot be effectively replaced.

[0005] To this end, the utility model provides a wear-resistant slurry gate valve. Utility Model Content

A swinging closing door is swingably connected to the left side surface of the mortar filter box, and the outer surface of the swinging closing door is separated from the inner surface of the slurry stone filter box. When the surface of the swinging closing door has no squeezing force, the internal sand and gravel will be directly discharged and diverted out due to the inclination angle of the filter chute.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figures 1 to 5As shown, a wear-resistant slurry gate valve of an embodiment of the utility model comprises a slurry gate valve pipeline 11, one end of the slurry gate valve pipeline 11 is movably sleeved with a docking sealing unit, the docking sealing unit comprises an elastic push wire 111 and a docking sleeve 112, one end of the slurry gate valve pipeline 11 is movably sleeved with a double-layer filter unit, the double-layer filter unit comprises an overlap support plate 15 and a mortar filter box 16, one end of the docking water pipe 113 is fixedly connected with a slurry stone filter box 12, the outer surface of the overlap support plate 15 is fixedly connected to the inner wall surface of the slurry stone filter box 12, and the mortar filter box The bottom surface of 16 is movably overlapped on the top surface of the overlap support table 15, and the mortar filter box 16 is pulled from the surface of the overlap support table 15 to the surface of the overlap inclined plate 13. The outer wall surface of the mortar filter box 16 is fixedly connected with a closed sealing plate 14, and the outer surface of the slurry stone filter box 12 is fixedly connected with an overlap inclined plate 13. When one of the two mortar filter boxes 16 is cleaning sand and gravel, the other mortar filter box 16 can continue to filter sand and gravel. When the mortar filter box 16 is put back into the slurry stone filter box 12, the slurry is filtered with the closed sealing plate 14. The opening of the stone filter box 12 is sealed, and the bottom surface of the closed sealing plate 14 and the mortar filter box 16 are movably overlapped on the top surface of the overlapped inclined plate 13. A filter chute 161 is provided on the inner surface of the mortar filter box 16, and the mortar is poured into the slurry filter box 12 in cooperation with the slurry gate valve pipeline 11. The mortar entering the slurry filter box 12 is contacted and filtered in cooperation with the inclination angle on the surface of the filter chute 161. Since one end of the filter chute 161 is higher than the other end, when the mortar contacts, the mortar will flow to the lower end, and the higher end of the filter chute 161 is in the mortar. Under the scouring, the sand and gravel remaining on the top of the filter chute 161 will be washed to a lower place, so that the filter chute 161 always has the efficiency of filtering sand and gravel, and will not be blocked due to the sand and gravel and mud being spread on the surface of the filter layer, making it impossible to filter. The left surface of the mortar filter box 16 is swingably connected with a swing closing door 162, and the outer surface of the swing closing door 162 is separated from the inner surface of the slurry stone filter box 12. When the surface of the swing closing door 162 has no squeezing force, the internal sand and gravel will be directly discharged and diverted out due to the inclination angle of the filter chute 161.

[0026] like Figures 1 to 5As shown, one end of the elastic push wire 111 is fixedly connected to the outer surface of the flange of the slurry gate valve pipeline 11, and one end of the elastic push wire 111 is fixedly connected to the outer surface of the docking sleeve 112. The elastic push wire 111 is used to elastically push the docking sleeve 112, and one end of the docking sleeve 112 is sleeved on one end surface of the docking water pipe 113. At the same time, the width of the docking sleeve 112 is used to dock the slurry gate valve pipeline 11 and the docking water pipe 113, thereby increasing stability and the docking sleeve The inner surface of the tube 112 is movably sleeved on the outer surface of one end of the slurry gate valve pipeline 11, and a docking water pipe 113 is movably sleeved on the inner surface of the docking sleeve 112. When the slurry stone filter box 12 needs to be replaced due to wear, it is only necessary to pull the docking sleeve 112 to peel it off from one end of the docking water pipe 113, replace or repair the slurry stone filter box 12, and then dock and fit the docking water pipes 113 on both ends of the slurry stone filter box 12 with one end of the slurry gate valve pipeline 11.

[0027] Working principle: cooperate with the slurry gate valve pipeline 11 to inject mortar into the interior of the slurry stone filter box 12, and cooperate with the inclination angle on the surface of the filter chute 161 to contact and filter the mortar that is diverted in. Since one end of the filter chute 161 is higher than the other end, when the mortar contacts, the mortar will flow to the lower end, and the higher end of the filter chute 161 will flush the sand and gravel remaining on the top of the filter chute 161 to the lower place under the flushing of the mortar, so that the filter chute 161 always has the efficiency of filtering sand and gravel, and will not be blocked due to the sand and gravel and mud being spread on the surface of the filter layer, and filtering cannot be performed. The mortar filter box 16 is pulled from the surface of the overlapping support table 15 to the surface of the overlapping inclined plate 13, and the outer surface of the swing closing door 162 is separated from the inner surface of the slurry stone filter box 12. When the surface of the swing closing door 162 has no squeezing force, the internal sand and gravel will be due to the inclination angle of the filter chute 161. The discharge is directly diverted out. When one of the two mortar filter boxes 16 is cleaning sand and gravel, the other mortar filter box 16 can continue to filter sand and gravel. When the mortar filter box 16 is put back into the slurry stone filter box 12, the opening of the slurry stone filter box 12 is sealed in cooperation with the closing sealing plate 14. When the slurry stone filter box 12 needs to be replaced due to wear, it is only necessary to pull the docking sleeve 112 to peel it off from one end of the docking water pipe 113, replace or repair the slurry stone filter box 12, and then dock and fit the docking water pipes 113 on both ends of the slurry stone filter box 12 with one end of the slurry gate valve pipeline 11, and cooperate with the elastic pushing wire 111 to elastically push the docking sleeve 112, so that one end of the docking sleeve 112 is sleeved on the surface of one end of the docking water pipe 113, and at the same time, cooperate with the width of the docking sleeve 112 to dock the slurry gate valve pipeline 11 and the docking water pipe 113 to increase stability.
