Description
Technical Field
[0001] This utility model relates to the field of mud prewashing technology, and in particular to a mud prewashing water tank. Background Technology
[0002] Sand and gravel are widely used in the construction industry, sand and gravel plants, mines, transportation, and chemical industries. As the demand for sand in various fields continues to increase, the requirements for sand and gravel washing efficiency and the quality of the finished product are becoming increasingly stringent. However, most fine sand recovery machines on the market today are not equipped with a pre-washing process before the slurry enters the hydrocyclone. When the slurry contains a large number of impurities with a density less than water, the lack of a pre-washing process will significantly affect the quality of the subsequent solid particle finished product.
[0003] In the prior art, Chinese patent CN215234980U discloses a sand washing machine with a floating debris removal function. A filter box is installed on one side of the sand washing machine casing, and a water circulation is formed between the sand washing machine casing, the filter box, and the water tank. Floating debris on the surface of the sand washing machine casing is guided into the filter box by the water flow through the overflow port. The filter screen traps the floating debris, which can be discharged from the floating debris outlet using tools such as brushes. Dust and sludge in the water settle and accumulate at the guide slope. However, this solution has drawbacks. When the sand washing wheel agitates the material, dust, sludge, and floating debris mix, and some dust and sludge are discharged with the floating debris, reducing the yield.
[0004] Therefore, it is necessary to propose a mud pre-washing tank that can not only remove impurities with low density and light weight, thus improving the quality of the finished product, but also reduce dust and sludge overflow, thereby increasing the yield. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a mud pre-washing tank.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A mud pre-washing tank includes a tank body, an anti-turbulence box, several anti-turbulence plates, a discharge pump, and an overflow tank; The anti-turbulence box and anti-turbulence plate are cylindrical structures that run vertically through each other. The anti-turbulence box and all anti-turbulence plates are arranged in sequence from the inside to the outside on the upper inner side of the main body of the water tank. The lower part of the main body of the water tank is provided with a first discharge port. The discharge pump is installed at the first discharge port. A sedimentation zone is formed below the anti-turbulence box and anti-turbulence plate. The mud contains mud and light impurities. The anti-turbulence box, anti-turbulence plate, sedimentation zone and discharge pump form a pre-washing channel for mud and sand. An overflow trough is arranged around the outside of the main body of the water tank. The overflow trough is equipped with a second discharge port. The area above the main body of the water tank, the overflow trough and the second discharge port form an overflow channel for light impurities.
[0007] Preferably, the device also includes a mounting plate. The anti-turbulence box includes a mounting section and a mesh section. The mesh section is installed at the bottom of the mounting section, and the mounting section is fixedly connected to the inner side of the mounting plate. The mounting plate is positioned across the top of the water tank body and is used to prevent light impurities overflowing from the top of the mounting section from flowing back into the mounting section.
[0008] Preferably, the main body of the water tank includes a cone, the inner diameter of which gradually decreases from top to bottom.
[0009] Preferably, the main body of the water tank also includes a fixed ring and a movable ring. The fixed ring is fixedly installed at the top of the cone, and the movable ring is sleeved on the outside of the fixed ring. The fixed ring has a fixed hole, and the movable ring has a longitudinal strip hole. The relative position of the fixed hole and the longitudinal strip hole is fixed by bolts so as to adjust the relative height of the movable ring and the fixed ring along the longitudinal strip hole.
[0010] Preferably, the discharge pump inlet faces the bottom surface of the cone.
[0011] Preferably, the lower part of the main body of the sink is also provided with a cleaning port for draining the main body of the sink.
[0012] Preferably, the bottom surface of the inner wall of the overflow trough is inclined relative to the horizontal plane, and the second discharge port is located at the lowest point on the side wall of the overflow trough.
[0013] Preferably, the top of the overflow trough is not higher than the top of the main body of the water tank.
[0014] Preferably, all anti-turbulence plates are at the same height as the top of the main body of the water tank.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) By setting up anti-turbulence boxes and anti-turbulence plates in the main body of the water tank, the water and mud in the main body of the water tank are kept in a stable flow state, which helps the mud and sand in the mud to settle to the bottom of the sedimentation zone.
[0016] (2) Through the design of the mounting plate and the anti-turbulence box, the anti-turbulence box is higher than the top of the main body of the water tank. Light impurities overflowing from the anti-turbulence box will only float on the outside of the anti-turbulence box, which helps to improve the pre-washing effect.
[0017] (3) By designing the pump outlet of the discharge pump to face the bottom of the cone, the sedimentation efficiency of mud and sand is accelerated and the pre-washing efficiency is improved.
[0018] (4) By designing fixed rings and movable rings, the relative height between movable rings and fixed rings can be adjusted, thereby adjusting the relative height between the top of the water tank body and the top of the overflow tank to adapt to different mud conditions, avoid backflow of light impurities in the overflow tank, and improve the pre-washing effect.
[0019] (5) By setting the bottom of the inner wall of the overflow tank at an inclination, the second discharge port is located at the lowest point on the side wall of the overflow tank, which helps to improve the efficiency of light impurity discharge, thereby improving the pre-washing efficiency.

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. The accompanying drawings are merely illustrative to facilitate understanding of the present invention, and their specific proportions can be adjusted according to design requirements. The vertical relationships of relative elements and the definitions of front / back in the graphics described herein should be understood by those skilled in the art to refer to the relative positions of the components; therefore, they can all be flipped to present the same component, and all of this should fall within the scope disclosed in this specification.
[0022] refer to Figures 1 to 6This application proposes a mud pre-washing tank, including a tank body 1, an anti-turbulence box 2, several anti-turbulence plates 3, a discharge pump 4, an overflow trough 5, and a mounting plate 6. The anti-turbulence box 2 and the anti-turbulence plates 3 are cylindrical structures that run vertically through each other, so that the mud and sand in the mud injected into the anti-turbulence box 2 and the mud and sand that have penetrated to the inside of the anti-turbulence plates 3 settle downwards. The anti-turbulence box 2 and all the anti-turbulence plates 3 are arranged sequentially and spaced apart from the inside to the outside on the upper inner side of the tank body 1 to slow down the outward diffusion speed of the mud in the mud. The lower part of the tank body 1 is provided with a first discharge port 11, and the discharge pump 4 is installed at the first discharge port 11. The anti-turbulence box 2 and the anti-turbulence plates 3 are arranged sequentially and spaced apart from the inside to the outside on the upper inner side of the tank body 1. A sedimentation zone is formed below the flow plate 3. The slurry contains silt and light impurities. After the slurry is injected into the anti-turbulence box 2, the light impurities in the slurry float on the surface of the liquid because their density is less than that of water. The silt in the slurry will rise or fall without restriction or guidance. The anti-turbulence box 2, the anti-turbulence plate 3, the sedimentation zone, and the discharge pump 4 form a pre-washing channel for the silt. Through the design of the anti-turbulence box 2 and the anti-turbulence plate 3, the outward velocity of the silt in the slurry is greatly reduced, which helps the silt to settle in the sedimentation zone. The silt settled in the pre-washing channel is pumped to the next process by the discharge pump 4. The pumping of the silt by the discharge pump 4 also helps to remove toxins from the silt. The overflow trough 5 is arranged around the outside of the main body of the water tank 1. The overflow trough 5 is provided with a second discharge port 51. The area above the main body of the water tank 1, the overflow trough 5, and the second discharge port 51 form an overflow channel for light impurities. The mud pre-washing tank proposed in this application stabilizes the liquid flow in the main body 1 of the tank through the design of the anti-turbulence box 2 and the anti-turbulence plate 3. This allows the light impurities with low density and light weight to overflow and be discharged after the mud is injected, while the heavy mud containing sand and gravel is settled and pumped. This reduces the overflow of solid particles, not only achieving pre-washing of the mud and improving the quality of the finished sand and gravel products, but also increasing the yield.
[0023] In a specific embodiment, the anti-turbulence box 2 includes a mounting portion 21 and a mesh portion 22. The mesh portion 22 is installed at the bottom end of the mounting portion 21, and the mounting portion 21 is fixedly connected to the inner side of the mounting plate 6. The mounting plate 6 is horizontally disposed above the water tank body 1, and is used to prevent light impurities overflowing from above the mounting portion 21 from flowing back into the mounting portion 21. The anti-turbulence plate 3 is installed at the bottom of the mounting plate 6. In the embodiments of this application, two mounting plates 6 are provided to make the position of the anti-turbulence 2 within the water tank body 1 more stable. After the mud is injected into the anti-turbulence box 2, light impurities overflow from the top of the anti-turbulence box 2. The overflowing light impurities float on the liquid surface inside the main body of the water tank 1. Since the mounting part 21 of the anti-turbulence box 2 is installed inside the mounting plate 6, and the mounting plate 6 is installed above the main body of the water tank 1, the mounting part 21 of the anti-turbulence box 2 is higher than the main body of the water tank 1. Through the cooperative design of the mounting plate 6 and the anti-turbulence box 2, the light impurities overflowing from the anti-turbulence box 2 will only float on the outside of the anti-turbulence box 2. The light impurities in the injected mud will only overflow from the anti-turbulence box 2, which helps to improve the pre-washing effect and will not cause too many light impurities to accumulate at the mouth of the anti-turbulence box 2, affecting the continued injection of mud. It also prevents light impurities from carrying away solid particles such as mud and sand and overflowing out of the anti-turbulence box 2.
[0024] In a specific embodiment, the water tank body 1 includes a cone 12, the inner diameter of which gradually decreases from top to bottom. The pump port of the discharge pump 4 faces the bottom surface of the cone 12 and is inverted. The discharge pump 4 is used to pump the mud and sand at the bottom of the water tank body 1 to the next process. Since the pump port of the discharge pump 4 is inverted, the mud and sand obtained by pre-washing and sedimentation is pumped out of the water tank body 1 through the pump port. The suction of the pump port affects the flow rate at the bottom of the water tank body 1. At the same time, the inner diameter of the cone 12 of the water tank body 1 gradually decreases from top to bottom, which accelerates the sedimentation speed of the mud and sand near the bottom of the water tank body 1 and improves the pre-washing efficiency of the mud.
[0025] In a specific embodiment, the main body 1 of the water tank also includes a fixed ring 13 and a movable ring 14. The fixed ring 13 is fixedly installed at the top of the cone 12, and the movable ring 14 is sleeved on the outside of the fixed ring 13. The fixed ring 13 has a fixing hole 131, and the movable ring 14 has a longitudinal strip hole 141. The relative positions of the fixing hole 131 and the longitudinal strip hole 141 are fixed by bolts to adjust the relative height of the movable ring 14 and the fixed ring 13 along the longitudinal strip hole 141. Furthermore, the top of the overflow trough 5 is not higher than the top of the main body 1 of the water tank to prevent light impurities from overflowing and flowing back into the main body 1 of the water tank. When the mud contains a large amount of light impurities, the fixing hole 131 is fixed in the lower half of the longitudinal strip hole 141 by bolts, raising the height of the movable ring 14 relative to the top of the overflow trough 5 to prevent excessive accumulation of light impurities in the overflow trough 5 and overflow back into the water tank body 1. Conversely, when the mud contains less light impurities, the fixing hole 131 is fixed in the upper half of the longitudinal strip hole 141, lowering the height of the movable ring 14 relative to the top of the overflow trough 5. In the embodiments of this application, the movable ring 14 can also be removed if light impurities flow back into the water tank body 1 from the overflow trough 5 when they are higher than the overflow trough 5. Since the mounting plate 6 spans across the water tank body 1, the height of the anti-turbulence box 2 and the anti-turbulence plate 3 relative to the top of the water tank body 1 remains unchanged. In a specific embodiment, all anti-turbulence plates 3 are at the same height as the top of the water tank body 1. By designing the fixed ring 13 and the movable ring 14, the relative height between the movable ring 14 and the fixed ring 13 can be adjusted, thereby adjusting the relative height between the top of the water tank body 1 and the top of the overflow tank 5 to adapt to different mud conditions, prevent light impurities in the overflow tank 5 from flowing back, and improve the pre-washing effect.
[0026] In a specific embodiment, the lower part of the water tank body 1 is also provided with a cleaning port 15, which is used to drain the water tank body 1. In the embodiment of this application, a flange and a valve are connected to the cleaning port 15. The valve is normally closed and is opened when the water tank body 1 needs to be cleaned.
[0027] In a specific embodiment, the bottom surface of the inner wall of the overflow tank 5 is inclined relative to the horizontal plane, and the second discharge port 51 is located at the lowest point on the side wall of the overflow tank 5. This helps light impurities to float toward the second discharge port 51 under the action of gravity and be discharged from the second discharge port 51, thereby improving the efficiency of light impurity discharge and thus improving the pre-washing efficiency.
[0028] The following describes a specific working process to further illustrate the mud prewashing tank proposed in this application.
[0029] The mud pre-washing tank of this application is connected to a water supply system, which is used to continuously supply water to the main body of the tank 1.
[0030] Before starting the pre-wash, fill the main body of the sink 1 with water.
[0031] During pre-washing, the mud is injected into the anti-turbulence box 2. The anti-turbulence box 2 guides the mud feed radially. The mud and sand in the mud gradually spread and are evenly distributed in the anti-turbulence box 2, and gradually sink. Light impurities have a lower density than water, so they float to the top.
[0032] In the anti-turbulence sedimentation process, in this embodiment, the number of anti-turbulence plates 3 is one. Sediment with a particle size range of 0.075~5mm seeps out from the mesh portion 22 of the anti-turbulence box 2 and enters between the anti-turbulence box 2 and the anti-turbulence plate 3. The anti-turbulence plate 3 prevents the sediment from continuing to diffuse outward and settles it in the sedimentation zone. In other embodiments, multiple anti-turbulence plates 3 can be provided. The distance between the bottom of the anti-turbulence plate 3 and the bottom of the water tank body 1 gradually decreases from the inside out. As the sediment settles downward and diffuses outward, the anti-turbulence plate 3 also slows down the outward velocity of the sediment, helping it to settle into the sedimentation zone. Sediment with a particle size range greater than 5mm settles downward from the anti-turbulence box 2 into the sedimentation zone.
[0033] In the pumping process, in the embodiments of this application, the discharge pump 4 is a centrifugal pump with the pump outlet facing the ground of the water tank body 1. By setting the inverted pump outlet, the sedimentation speed of the mud and sand located in the lower part of the sedimentation zone to the bottom of the water tank body 1 is accelerated, which makes it easier to pump the mud and sand located at the bottom of the water tank body 1 to the next process for sand washing, mud removal and fine sand recovery.
[0034] During the overflow process, the water supply system continuously supplies water to the main body of the water tank 1, causing light impurities in the slurry to overflow from above the anti-turbulence box 2 to the other areas of the main body of the water tank 1 except for the anti-turbulence box 2. Light impurities floating above the main body of the water tank 1 and located at the edge of the main body of the water tank 1 overflow into the overflow trough 5. Light impurities located in the main body of the water tank 1 also gradually overflow towards the edge of the main body of the water tank 1. The light impurities overflowing into the overflow trough 5 are discharged from the second discharge port 51.
[0035] During the cleaning process, under normal use, the valve at the cleaning port 15 is normally closed; after use, if the tank is not used for a long time or if there is a blockage in the pipeline and the mud pre-washing tank needs to be cleaned, the valve is opened, and the liquid and mud in the main body 1 of the tank are drained through the cleaning port 15.
[0036] This application proposes a mud pre-washing tank suitable for pre-washing mud containing a large amount of light impurities with a density less than water. Pre-washing removes some of the impurities and improves the cleanliness of the finished solid particles, thereby increasing the yield and quality of the finished product in subsequent sand washing, desliming, and fine sand recovery processes. This solves the problem of existing sand washing technologies failing to pre-wash, which affects the quality of the finished product. Furthermore, during mud and sand pre-washing and sedimentation, the anti-turbulence box 2 and anti-turbulence plate 3 ensure a stable flow within the tank body 1, resulting in negligible mud and sand loss. This solves the problem of material loss caused by the mixing of dust, sludge, and floating matter in existing technologies. Further, the mud pre-washing tank body 1 is open, allowing air to enter when the mud enters the tank. Even if air enters, it will not affect the pumping operation of the discharge pump 4 at the bottom of the tank body 1.
[0037] The above embodiments are only used to further illustrate the technical solution of this utility model, but this utility model is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of the technical solution of this utility model.
