Description

Technical Field

[0001] The utility model belongs to the technical field of sand particle treatment, and particularly relates to a novel integrated device for sand washing and fine sand recovery. Background Art

[0002] A sand washer is a device for cleaning sand and gravel dug or mined. It mainly uses water for cleaning. Since the sand and gravel mined from the river bottom or rock formation still have a lot of impurities, it is not conducive to subsequent processing and use. Therefore, it is necessary to wash with water to separate the mud from the sand and gravel to achieve the purpose of purification. The wheel bucket sand washer is a newly emerging water washing device in recent years. It can wash fine sand, coarse sand or stones and separate them, so it has a wide range of uses and a large social demand. However, the existing sand washers on the market only convey the crushed mixed sand and gravel into the cabin of the stone washer, and then tumble and vibrate. However, the mud on some sand and gravel cannot be cleaned once, and subsequent high-pressure water guns need to be used for spraying and washing to meet the use requirements, thus reducing the sand washing efficiency.

[0003] For this reason, a fine sand recovery device for a sand washer with the publication number of "CN213494254U" belongs to the technical field of construction machinery, and includes a wheel bucket, a fine sand collection box, a mud collection box, a cleaning tank and a chassis. The top of the chassis is provided with a cleaning tank, the top of the cleaning tank is movably provided with a wheel bucket, a fine sand collection box is arranged behind the wheel bucket, the top of the fine sand collection box is communicated with the mud collection box, and the bottom of the fine sand collection box is communicated with the cleaning tank. When in use, the wheel bucket rotates, and at the same time, the sand and gravel mixture in the cleaning tank is brought into the wheel bucket. Under the action of gravity and centrifugal force, the coarse sand will be thrown out of the cleaning tank by the wheel bucket. At the same time, the fine sand and mud are brought into the fine sand collection box, and the fine sand will precipitate below the mud. With the continuous injection of clean water, the mud continuously flows into the mud collection box, while the fine sand flows back into the cleaning tank, and thus the fine sand is continuously washed in a cycle to obtain clean fine sand. It can effectively separate the sand and gravel mixture and ensure the quality of the washed sand and gravel.

[0004] However, for the above-mentioned fine sand recovery device of the sand washer, although the motor drives the wheel bucket to rotate, so that the wheel blades separate the coarse sand onto the coarse sand inclined plane, and at the same time the fine sand and mud are continuously brought into the fine sand collection box by the wheel blades, there are still the following obvious defects in the use process: there are sand grains of different particle sizes in the mud, and in the above-mentioned filtration and recovery of the mud by the wheel blades, due to the presence of moisture, the filtered sand grains will adhere to the inner wall of the wheel blades, resulting in the problem that the wheel blades are blocked and the sand grains cannot be filtered. Content of the Utility Model

[0005] The purpose of the utility model is to provide a novel integrated device for sand washing and fine sand recovery to solve the problems mentioned in the above background art.

[0006] To achieve the above object, the utility model provides the following technical solutions: a new type of integrated sand washing and fine sand recovery device, which includes a sand washing tank, and a coarse sand chamber, a sand washing chamber, and a fine sand chamber formed inside the sand washing tank through a partition plate. A sand washing wheel for stirring, washing, and filtering sand is rotatably arranged in the sand washing chamber through a provided installation strip plate. A high-pressure suction hopper for adsorbing and discharging the larger-particle sand filtered in the sand washing wheel into the coarse sand chamber is installed on the partition plate on one side of the sand washing wheel. A strip-shaped air blowing cleaning plate for air-blowing and cleaning the sand particles adsorbed on the sand washing wheel penetrates through the vertical plate provided at the end of the high-pressure suction hopper. The air blowing cleaning plate is connected to a high-pressure air blowing pump arranged at the upper end inside the coarse sand chamber. The high-pressure air blowing pump is provided with a fixed plate and is provided with a high-pressure suction pump connected to the high-pressure suction hopper for adsorbing and collecting coarse sand.

[0007] Preferably, a fine sand sedimentation hopper penetrates through the lower end surface of the sand washing tank and is located at the position of the sand washing chamber. The bottom end of the fine sand sedimentation hopper is connected to a pumping pump through a pipeline, and the fine sand precipitated in the fine sand sedimentation hopper can be pumped out and collected inside the fine sand chamber.

[0008] Preferably, the output end of the pumping pump is connected to a fine sand output pipe fitting. One end of the fine sand output pipe fitting penetrates into the fine sand chamber and is in the shape of an inclined discharge port, which can realize the adsorption and transportation of the precipitated fine sand into the fine sand chamber.

[0009] Preferably, the outer surface of the sand washing wheel is provided with sand washing filter hoppers in a trapezoidal structure. The inner side walls of both sides of the sand washing filter hopper are in a mesh structure, which is beneficial for sand washing and filtering. A blocking strip plate extending to one side is provided on one inner side wall of the sand washing filter hopper to block the filtered sand particles.

[0010] Preferably, a high-pressure air blowing pipe is connected to the air outlet port of the high-pressure air blowing pump. The other end of the high-pressure air blowing pipe is communicated with the air inlet port of the air blowing cleaning plate. A suction pipe fitting is connected to the suction port of the high-pressure suction pump. The other end of the suction pipe fitting is connected to the discharge port end of the high-pressure suction hopper, which can blow and clean the sand particles adhered inside the sand washing filter hopper to avoid adhering to the inner wall of the sand washing filter hopper.

[0011] Preferably, a discharge port penetrates through one side of the fine sand chamber. A baffle plate for blocking the discharge port in a pull-up manner is provided outside the outer port of the discharge port and on one side wall outside the sand washing tank to realize the discharge and transfer use of the fine sand.

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows: For this new integrated sand washing and fine sand recovery device, through the combination of the high-pressure air blowing pump, high-pressure air blowing pipe arranged in the coarse sand chamber, and the high-pressure suction hopper, air blowing cleaning plate, and suction pipe fittings installed at the end of a partition board, and in cooperation with the sand washing wheel driving the sand washing filter hopper, the sand washing wheel drives the sand washing filter hopper to rotate in the sand washing chamber, enabling the sand washing filter hopper to dig and rotate the slurry to filter out larger sand grains in the slurry, allowing the sand grains to remain in the sand washing filter hopper and continue to rotate. Moreover, by using the combination of the air blowing cleaning plate, high-pressure air blowing pipe, and high-pressure air blowing pump to generate high-pressure gas and blow it inside the sand washing filter hopper, the sand grains adhered to the receiving rods on the inner wall of the sand washing filter hopper can be blown off the inner wall, thus avoiding the problem of sand grains adhering to the inner wall of the sand washing filter hopper.

[0013] Meanwhile, as the sand washing filter hopper continues to rotate, the high-pressure suction hopper generates high-pressure suction to adsorb and transport the sand grains that have detached from the inner wall of the sand washing filter hopper to the coarse sand chamber for collection. Furthermore, it can prevent the phenomenon that the sand washing filter hopper is blocked by sand grains and unable to filter. Through the combined setting of the pumping pump and the fine sand sedimentation hopper, the precipitated fine sand can be pumped out and transported to the fine sand chamber for sedimentation separation, and the sedimentated muddy water overflows from the partition board and flows into the sand washing chamber to continue the sand washing and filtering process, thereby making the quality of the recovered fine sand better.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a new type of integrated sand washing and fine sand recovery device, which includes a sand washing tank 1, and a coarse sand chamber 3, a sand washing chamber 4 and a fine sand chamber 5 formed inside the sand washing tank 1 through a partition plate 2, so as to realize the sand washing and filtration of the slurry. The sand washing chamber 4 is rotatably provided with a sand washing wheel 6 for stirring, washing and filtering the sand through a provided mounting strip plate. One end of the rotating shaft of the sand washing wheel 6 penetrates to one side outside the sand washing tank 1 and is drivingly connected to a driving motor installed outside the sand washing tank 1. The driving motor drives the sand washing wheel 6 to rotate to perform sand washing and filtration of the slurry, separating sand grains with larger particles from the fine sand, so as to further improve the quality of the washed fine sand. A high-pressure suction hopper 7 for adsorbing and discharging the coarse sand filtered in the sand washing wheel 6 into the coarse sand chamber 3 is installed on the partition plate 2 on one side of the sand washing wheel 6, which can adsorb and collect the larger filtered sand grains inside the coarse sand chamber 3. A gas blowing cleaning plate 8 which is in a strip structure and is used for gas blowing and cleaning the sand grains adsorbed on the sand washing wheel 6 penetrates through the vertical plate provided at the end of the high-pressure suction hopper 7, which can clean and separate the larger sand grains adhered to the inner wall of the sand washing filter hopper 14, reducing the phenomenon of sand grains adhering to the inner wall. The gas blowing cleaning plate 8 is connected to a high-pressure gas blowing pump 9 provided at the upper end inside the coarse sand chamber 3, and the high-pressure gas blowing pump 9 outputs high-pressure gas, which can blow and clean the large-particle sand on the inner wall of the sand washing filter hopper 14 away from the inner wall. The high-pressure gas blowing pump 9 is provided with a high-pressure suction pump 10 which is communicated with the high-pressure suction hopper 7 through a fixed plate to adsorb and collect the coarse sand, so as to achieve the effect of strongly adsorbing the large particles separated from the inner wall of the sand washing filter hopper 14, avoiding the existence of large-particle sand in the recovered fine sand, and improving the uniformity of the quality of the fine sand particles.

[0020] The lower end surface of the sand washing tank 1 and at the position of the sand washing cavity 4 is provided with a fine sand sedimentation hopper 11. At the inner bottom of the sand washing cavity 4, there is a hopper with a semi-circular arc surface. At the inner bottom of the hopper, there is a coarse sand filter plate that is arc-shaped and communicates with the fine sand sedimentation hopper 11. The rotation of the sand washing wheel 5 allows the sand washing filter hopper 14 to scrape and clean the inside of the hopper, which can avoid the phenomenon that the coarse sand filter plate is blocked by coarse sand and the fine sand cannot flow downward. Thus, all sand grains can be kept in an active state. The fine sand falls and settles into the fine sand sedimentation hopper 11. The bottom end of the fine sand sedimentation hopper 11 is connected to a pumping pump 12 through a pipeline, which can extract and transport the settled fine sand to the fine sand cavity 5. And the existing moisture flows into the sand washing cavity 4 through the overflow hole grooves provided on its inner wall. And in the sand washing cavity 4, water is pumped in through an external water pump to wash the sand grains in the slurry. The output end of the pumping pump 12 is connected to a fine sand output pipe fitting 13. One end of the fine sand output pipe fitting 13 penetrates into the inside of the fine sand cavity 5 and is in the shape of a discharge inclined opening. The outer surfaces of the sand washing wheels 6 are all provided with sand washing filter hoppers 14 in a trapezoidal structure to filter larger granular sand grains. The fine sand settles inside the fine sand sedimentation hopper 11. The inner side walls of the sand washing filter hopper 14 are in a mesh structure, which is conducive to sand washing and filtering. On one inner side wall of the sand washing filter hopper 14, there is a blocking strip plate 15 extending to one side, which plays a role in blocking the filtered large granular sand during the rotary filtration, avoiding the sand grains from falling into the sand washing cavity 4 during rotation.

[0021] A high-pressure air blowing pipe 16 is connected to the air outlet port of the high-pressure air blowing pump 9. The high-pressure gas generated by the high-pressure air blowing pump 9 is transported to the air blowing cleaning plate 8 through the high-pressure air blowing pipe 16 for jet cleaning of the adhered sand grains. The other end of the high-pressure air blowing pipe 16 communicates with the air inlet port of the air blowing cleaning plate 8, realizing the air blowing cleaning and detachment of the large granular sand grains adhered to the inner wall of the sand washing filter hopper 14, and facilitating the adsorption and collection of the large granular sand. A suction pipe fitting 17 is connected to the suction port of the high-pressure suction pump 10, so that the recovered large granular sand is transported through the suction pipe fitting 17 to the inside of the coarse sand cavity 3 for collection and used in other places. The other end of the suction pipe fitting 17 is connected to the discharge port end of the high-pressure suction hopper 7. On one side of the fine sand cavity 5, there is a discharge port 18, through which the collected fine sand can be discharged to the outside for transfer and transportation. At the same time, outside the port of the discharge port 18 of the coarse sand cavity 3 and on the outer side wall of the sand washing tank 1, there is a baffle plate part 19 that is a pull-up type to block the discharge port 18. The upper end of the baffle plate part 19 is movably inserted through a limit sleeve fixed to the upper end of the outer right side wall of the sand washing tank 1, and the bottom end of the baffle plate part 19 is movably inserted into a support socket fixed to the bottom end of the outer right side of the sand washing tank 1, which is used to block the discharge port 18.

[0022] Specifically, when in use, first put the broken mud mixture into the sand washing chamber 4, and flush it by introducing clear water into the sand washing chamber 4 through an external water pump. Then start the driving motor to drive the sand washing wheel 6 to rotate inside the sand washing chamber 4, so that the sand washing wheel 6 drives the sand washing filter hopper 14 with a filter mesh inner wall to rotate inside the sand washing chamber 4. The rotation of the sand washing filter hopper 14 separates the coarse sand into its interior and is blocked by the blocking strip 15, so that the coarse sand remains inside the sand washing filter hopper 14 and continuously rotates with the sand washing wheel 6 to the other side of the sand washing chamber 4. At the same time, the high-pressure air blowing pump 9 generates high-pressure gas and transports it into the high-pressure air blowing pipe 16 and then into the interior of the air blowing cleaning plate 8 and discharges it. Due to the inclined downward setting of the air blowing cleaning plate 8, the rotating sand washing filter hopper 14 is passed, and the high-pressure gas covers and blows on the inner wall of the sand washing filter hopper 14 to perform high-pressure air blowing cleaning on the coarse sand adhered to the inner wall, so that the coarse sand detaches from the interior of the sand washing filter hopper 14. At this time, the high-pressure gas generated by the high-pressure suction pump 10 makes the high-pressure suction hopper 7 generate a large adsorption force, and the coarse sand cleaned and detached from the inner wall can be adsorbed and discharged into the interior of the coarse sand chamber 3. At the same time, the fine sand flows downward through the coarse sand filter plate into the interior of the fine sand sedimentation hopper 11. The coarse sand can scrape and clean the coarse sand on the surface of the coarse sand filter plate by the rotation of the sand washing wheel 6 driving the sand washing filter hopper 14 to rotate, and rotate and convey for suction cleaning, and use the pumping pump 12 to pump out the precipitated fine sand and transport it to the fine sand chamber 5. And the carried mud flows into the interior of the sand washing chamber 4 through the overflow port on the partition plate 2, so that the sand washing is sedimented and collected inside the fine sand chamber 5 within a certain time until all the fine sand is washed clean.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
