Description

Technical Field

[0001] This utility model relates to the field of waste rock sand making technology, and in particular to a mud and water recycling device. Background Technology

[0002] In the process of making sand from waste rock, a large amount of wastewater is generally generated, and the wastewater often contains a large amount of fine sand. In order to improve the utilization rate of resources, not only is the fine sand in the wastewater recycled, but the wastewater is also recycled to facilitate the recycling of water resources. Therefore, a mud-water recycling device is needed to realize the recycling of wastewater.

[0003] Most existing mud-water recycling devices employ processes such as sedimentation, separation, flocculation, pressure filtration, and dewatering to recycle mud-water. When mud-water is added to the sedimentation tank, a partition chamber is installed to prevent large sand particles from clogging the pipes, thus performing preliminary filtration. However, after filtration, a large amount of sand often accumulates in the partition chamber, which existing devices cannot clean. This can easily lead to blockage of the partition chamber, hindering preliminary filtration and resulting in low filtration efficiency. Consequently, this hinders subsequent recycling and reuse of mud-water. Utility Model Content

[0004] This invention proposes a mud-water recycling device to solve the problem that existing devices cannot clean the sand accumulated in the dividing chamber, which easily leads to blockage of the dividing chamber and is not conducive to the initial filtration of mud and water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mud-water recycling device, comprising a box body, an inlet pipe connected to the box body, and a door hinged to the front side of the box body. Inside the box body, a horizontal plate, a mud-water treatment structure, and a clean water tank are installed, and a drain pipe extending to the outside of the box body is connected to one side of the clean water tank. A sedimentation tank communicating with the mud-water treatment structure and the clean water tank is also installed on the horizontal plate, and a detachable filter structure is provided on the sedimentation tank.

The side of the filter frame with the opening has a sliding groove that matches the guide rail. One end of the filter frame is fitted with a cover plate to seal the slot, and the other end is fitted with a positioning block. The inner wall of the sedimentation tank also has positioning holes for inserting the positioning block.

[0007] Preferably, a support rod is also installed inside the filter frame, and a conical diverter plate is fixed to the top of the support rod.

The water outlet of the nozzles faces the inside of the sedimentation tank and the filter frame. The bottom of the sedimentation tank is connected to a waste discharge pipe extending to the outside of the tank.

[0009] Preferably, the sludge treatment structure includes a hydrocyclone, a dewatering screen, and a sludge flocculation tank mounted on the horizontal plate, and a filter press located at the bottom of the housing. The sedimentation tank contains a submersible sludge pump and a sewage pump, and the submersible sludge pump is connected to the hydrocyclone via a sludge delivery pipe.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-8As shown, a mud and water recycling device includes a box 1, a water inlet pipe 2 connected to the box 1, and a door hinged to the front of the box 1. Inside the box 1, a horizontal plate, a mud and water treatment structure and a clean water tank 12 are installed, and a drain pipe 4 extending to the outside of the box 1 is connected to one side of the clean water tank 12. A sedimentation tank 7 connected to the mud and water treatment structure and the clean water tank 12 is also installed on the horizontal plate, and a detachable filter structure 13 is provided on the sedimentation tank 7.

[0028] The filter structure 13 includes a filter frame 132 with openings on one side and top. The bottom of the filter frame 132 has evenly distributed filter holes. The sedimentation tank 7 has a slot 136 for inserting the filter frame 132 into it. The inner wall of the sedimentation tank 7 is equipped with a guide rail 134. The side of the filter frame 132 with the opening has a sliding groove 138 that matches the guide rail 134. One end of the filter frame 132 is equipped with a cover plate 131 that seals the slot 136, and the other end is equipped with a positioning block 137. The inner wall of the sedimentation tank 7 is also equipped with a positioning hole 135 for inserting the positioning block 137.

[0029] Depend on Figures 1-3 As can be seen, the sludge treatment structure of this application includes a hydrocyclone 8, a dewatering screen 9, and a sludge flocculation tank 10 installed on a horizontal plate, and a filter press 11 installed at the bottom of the box body 1. The sedimentation tank 7 is equipped with a submersible sludge pump and a sewage pump. The submersible sludge pump is connected to the hydrocyclone 8 by a sludge delivery pipe 14. The sewage pump is connected to the sludge flocculation tank 10 by a pipe. The discharge end of the hydrocyclone 8 is connected to the feed end of the dewatering screen 9 by a sludge delivery pipe 15. The discharge end of the hydrocyclone 8 is connected to the sludge flocculation tank 10 by a pipe. The dewatering screen 9 is connected to the water outlet of the dewatering screen 9 by a water supply pipe 18, and the sludge discharge end of the dewatering screen 9 is connected to a first sludge discharge pipe 5 extending to the outside of the box body 1. The top of the sludge flocculation tank 10 is connected to the clear water box 12 by a clear water overflow pipe 16, and the bottom of the sludge flocculation tank 10 is connected to the filter press 11 by a water supply pipe 17. The sludge discharge end of the filter press 11 is connected to a second sludge discharge pipe 6 extending to the outside of the box body 1, and the drain end of the filter press 11 is connected to the clear water box 12 by a conveying pipe 19.

[0030] As described above, during the recovery of sand-making slurry, the slurry is fed into sedimentation tank 7 through inlet pipe 2 for sedimentation. After sedimentation for a period of time, the slurry is first pumped through a sewage pump into slurry flocculation tank 10 for flocculation. Then, the slurry and sand are fed into hydrocyclone 8 through submersible slurry pump and slurry delivery pipe 14 for separation. At this time, the slurry is discharged into slurry flocculation tank 10 through a pipeline for flocculation, while the slurry and sand are fed into dewatering screen 9 through mud delivery pipe 15 for further dewatering. After dewatering, the slurry and sand are discharged through the first mud pipe 5 to... Externally, clean water is discharged into the clean water tank 12 through the water supply pipe 18 for storage. The mud and water flocculation tank 10 treats the mud and water by flocculation and discharges it into the filter press 11 through the water supply pipe 17 for filter pressing. After treatment, the clean water is transported into the clean water tank 12 through the conveying pipe 19 for storage, while the mud and sand are discharged through the second mud pipe 6. Then, the clean water in the clean water tank 12 can be discharged to the outside through the drain pipe 4 for external use, thereby realizing the recycling of mud and water, which is conducive to the recycling of mud and water and achieves the purpose of saving water resources.

[0031] When the muddy water is discharged through the inlet pipe 2, it first falls into the filter frame 132 and then is filtered through the filter holes at the bottom of the filter frame 132. This allows larger sand particles in the muddy water to be blocked in the filter frame 132, while the muddy water is discharged into the sedimentation tank 7 through the filter holes for sedimentation. This achieves the filtration of the muddy water and prevents larger sand particles in the muddy water from causing pipe blockage, which is conducive to the recycling of muddy water.

[0032] Secondly, when a large amount of sand accumulates inside the filter frame 132, the cover plate 131 can be pulled by the handle to pull the filter frame 132 out from the slot 136. At this time, the filter frame 132 slides along the guide rail 134 through the slide groove 138, and drives the positioning block 137 to move out from the positioning hole 135. Then, the sand accumulated inside the filter frame 132 is poured out and the filter frame 132 is cleaned. Then, the filter frame 132 is inserted into the sedimentation tank 7 through the slot 136 through the cover plate 131 until the positioning block 137 is inserted into the corresponding positioning hole 135 to realize the insertion and fixation of the filter frame 132, thus completing the installation of the filter frame 132. This enables the quick disassembly and assembly of the filter frame 132, facilitates the timely cleaning of the sand accumulated inside the filter frame 132, avoids the filter frame 132 from becoming clogged, and is conducive to the normal use of the filter frame 132, achieving efficient filtration of mud and water and facilitating the recycling of mud and water.

[0033] Furthermore, to facilitate the pulling of the cover plate 131, such as Figures 3-6 As shown, a handle is also installed on the side wall of the cover plate 131.

[0034] Meanwhile, in this embodiment, such as Figures 4-7 As shown, a support rod 139 is also installed inside the filter frame 132, and a conical diverter plate 133 is fixed to the top of the support rod 139.

[0035] When the muddy water discharged from the inlet pipe 2 falls into the filter frame 132, it will first fall onto the conical distribution plate 133, and then flow evenly along the distribution plate 133 to the four sides of the interior of the filter frame 132. Then it will be evenly filtered through the filter holes at the bottom of the filter frame 132, which helps to improve the effect of the initial filtration of muddy water, facilitates the efficient filtration of muddy water, and further facilitates the subsequent treatment of muddy water.

[0036] Additionally, in one embodiment, such as Figures 3-6 As shown, it also includes a spray mechanism for rinsing the sedimentation tank 7 and the filter frame 132. The spray mechanism includes a clean water pump built into the clean water tank 12 and a water distribution ring 21 fixed to the top inside the sedimentation tank 7. A cleaning pipe 20 is connected between the water distribution ring 21 and the clean water pump. The water distribution ring 21 is also equipped with evenly distributed nozzles 22. The water outlet of the nozzles 22 faces the inside of the sedimentation tank 7 and the filter frame 132. The bottom of the sedimentation tank 7 is connected to a waste discharge pipe 3 extending to the outside of the tank body 1. An electric valve is installed on the waste discharge pipe 3 to facilitate the discharge of waste from the sedimentation tank 7.

[0037] After the mud and water treatment, the clean water in the clean water tank 12 can be pumped out by the clean water pump and sent into the water distribution ring 21 through the cleaning pipe 20. Then, the clean water is sprayed into the interior of the filter frame 132 and the sedimentation tank 7 through the nozzle 22, thereby rinsing the interior of the filter frame 132 and the sedimentation tank 7. After rinsing, the wastewater is discharged through the waste discharge pipe 3, thereby cleaning the interior of the filter frame 132 and the sedimentation tank 7, avoiding the accumulation of scale inside the filter frame 132 and the sedimentation tank 7, which is beneficial to the subsequent use of the filter frame 132 and the sedimentation tank 7 and facilitates the use of subsequent mud and water treatment.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
