[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1, reference Figure 1-Figure 2 , which is the first embodiment of the present invention, and provides a sand and gravel filtering device for construction engineering, comprising a support leg 1 for supporting the entire device, a tank body 2 arranged on the support leg 1, a container for filtering sand and gravel, a loading and discharging unit 3 arranged on the tank body 2, for adding sand and gravel with filtration and discharging the filtered sand and gravel, a separation and filtration unit 4 arranged on the loading and discharging unit 3, for filtering the sand and gravel, and a power unit 5 arranged on the separation and filtration unit 4, for filtering muddy water and small-sized sand and gravel; The separation and filtration unit 4 includes a separation component 41 arranged on the tank body 2, which is used to drive the sand and gravel to roll, make the sand and gravel rub against each other, destroy the clumped sand and gravel, peel off the mud on the surface of the sand and gravel and break it up to form muddy water that is dissolved in water, and filter out large particles of sand and gravel; a waste discharge port 42 arranged on the separation component 41 is used to discharge the filtered large particles of sand and gravel; and a mud and water discharge component 43 arranged on the tank body 2 to cooperate with the separation component 41, which is used to discharge muddy water and sand and gravel with too small a particle size.

[0028] During use, water and sand and gravel to be filtered are first put into the separation component 41 from the feeding and discharging unit 3. At this time, the power unit 5 is started to drive the separation component 41 to rotate, so that the sand and gravel in the separation component 41 roll over, drive the sand and gravel to rub against each other, break up the agglomerated sand and gravel, and peel off the mud sticking on the sand and gravel through the friction between the sand and gravel, and grind it into water to form muddy water, so that all sand and gravel are not sticky to each other and the surface is clean. At the same time, the sand and gravel are fully in contact with the separation component 41, and large particles of sand and gravel are intercepted in the waste discharge port 42. At this time, the muddy water and the remaining sand and gravel pass through the separation component 41 and enter the muddy water discharge component 43 The mud and water discharge component 43 is provided with a soil component detection device for detecting the composition ratio of the mud in the discharged mud and water. When the soil component content is lower than the set value, it indicates that the sand and gravel are qualified for cleaning. The mud and water discharge component 43 cooperates with the rotation of the separation component 41 to drive the sand and gravel to move upward. While the sand and gravel are moving, the mud and water and sand and gravel with smaller particle size are discharged through the mud and water discharge component 43. At this time, the sand and gravel that meet the requirements and are in contact with the separation component 41 are discharged through the feeding and discharging unit 3 through the cooperation of the separation component 41 and the mud and water discharge component 43, and the remaining sand and gravel continue to be filtered and screened through the separation component 41 and the mud and water discharge component 43 to achieve continuous filtration.

[0029] Example 2, reference Figure 1-Figure 8 , which is the second embodiment of the present invention. Different from the previous embodiment, the sand and gravel are filtered, and the feeding and discharging unit 3 includes a fixed plate 31 arranged on the tank body 2, which plays a fixing role, a receiving plate 32 arranged on the fixed plate 31, which is used to put in sand and gravel and water, a connecting plate 33 arranged on the receiving plate 32, which is used to connect the separation component 41, the connecting plate 33 and the separation component 41 are rotatably connected, a connecting cavity 34 arranged between the fixed plate 31 and the connecting plate 33, which is a channel for the movement of qualified sand and gravel after filtration, and a discharge port 35 arranged on the fixed plate 31, and the discharge port 35 is arranged at the bottom of the fixed plate 31 for discharging the filtered sand and gravel.

[0030] The connecting cavity 34 is connected to the discharge port 35, and the separation component 41 and the mud and water discharge component 43 cooperate to send the qualified sand and gravel after filtration into the connecting cavity 34, and discharge them through the discharge port 35 for easy collection.

[0031] Among them, the separation component 41 includes a rotating drum 411 arranged on the tank body 2, which is used to hold sand and water to be filtered, a stirring blade 412 arranged on the inner wall of the rotating drum 411, which is used to turn over the sand and gravel in the rotating drum 411 through the stirring blade 412 when the rotating drum 411 rotates, a filter hole 413 arranged on the rotating drum 411, which is used to intercept sand and gravel with larger particle size, so that muddy water and remaining sand and gravel pass through and enter the mud and water discharge component 43 for the next step of filtration, and a spiral push plate 414 arranged on the outer wall of the rotating drum 411, which is used to cooperate with the rotating drum 411 to rotate and cooperate with the mud and water discharge component 43 to filter the remaining sand and gravel into the next step.

[0032] The tank body 2 is provided with a rotation cavity 21 for cooperating with the spiral push plate 414, so as to allow the spiral push plate 414 to rotate in the tank body 2; The drum 411 is arranged at an angle, and the waste discharge port 42 is arranged at the lower end of the drum 411, so that the large-particle sand and gravel intercepted by the filter holes 413 are retained in the waste discharge port 42 by gravity. The fixed plate 31 is arranged at the higher end of the drum 411, so that the water and the sand and gravel to be filtered can be fully turned over by the stirring blades 412, thereby improving the filtering effect.

[0033] The rotating chamber 21 is connected to the connecting chamber 34 , and is used to deliver sand and gravel into the connecting chamber 34 as the spiral push plate 414 rotates.

[0034] The muddy water discharge assembly 43 includes a filter plate 431 disposed on the rotating chamber 21, which is used to intercept sand and gravel with qualified particle sizes, so that muddy water and other sand and gravel with smaller particle sizes can pass through; a flow chamber 432 disposed between the filter plate 431 and the rotating chamber 21, which is used to conduct diversion; and a drainage pipe 433 disposed on the flow chamber 432, which is used to discharge muddy water and sand and gravel with smaller particle sizes. A soil component detection device is disposed on the drainage pipe 433, which is used to detect the composition ratio of soil in the discharged muddy water. When the soil component content is lower than the set value, it indicates that the sand and gravel cleaning is qualified. The drainage pipe 433 passes through the flow cavity 432 to the outside of the tank body 2. The drainage pipe 433 is arranged at one end of the flow cavity 432 close to the waste discharge port 42. In this way, it can cooperate with gravity to make the muddy water flush the flow cavity 432 when flowing, and can prevent sand and gravel with smaller particle size from remaining in the flow cavity 432 and causing damage and blockage.

[0035] The spiral push plate 414 contacts the inner wall of the filter plate 431 , which can drive the sand and gravel to fully contact the filter plate 431 , so that the sand and gravel with smaller particle sizes enter the flow cavity 432 .

[0036] The drum 411 is rotatably arranged on the connecting plate 33, so that the sand and water to be filtered can directly enter the drum 411 through the receiving plate 32 and the connecting plate 33, and the rotation of the drum 411 will not affect the loading and unloading of the loading and unloading unit 3; The waste discharge port 42 is rotatably arranged on the tank body 2 , and the waste discharge port 42 and the rotating drum 411 are fixedly connected, and cooperate with the connecting plate 33 to provide stable support for the rotating drum 411 , while not hindering the rotation of the rotating drum 411 .

[0037] The rest of the structure is the same as that of Example 1.

[0038] During use, when water and sand and gravel to be filtered enter the drum 411, the power unit 5 is started at this time, and the drum 411 is driven to rotate by driving the waste discharge port 42 to rotate. At this time, the stirring blades 412 turn over the sand and gravel in the drum 411 as the drum 411 rotates. At this time, the sand and gravel are constantly turned over, and the sand and gravel are constantly rubbed against each other, which destroys the clumped sand and gravel, and grinds the soil on the sand and gravel through mutual friction and dissolves it into muddy water. At this time, large-sized sand and gravel cannot pass through the filter holes 413, and are intercepted by the filter holes 413 and enter the waste discharge port 42 below. At this time, the muddy water and the remaining sand and gravel enter the rotating chamber 21 through the filter holes 413. Since the spiral push plate 414 rotates with the drum 411 at this time, the rotation of the spiral push plate 414 drives the sand and gravel in the rotating chamber 21 to be transported upward, enter the connecting chamber 34, and finally be discharged through the discharge port 35. In this process At this time, muddy water and sand and gravel with smaller particle sizes will pass through the filter plate 431 and enter the flow chamber 432 during the transportation process. Under the action of gravity, the muddy water flows downward and impacts the sand and gravel in the flow chamber 432 to prevent the flow chamber 432 from being blocked. Then the muddy water and sand and gravel with smaller particle sizes are discharged through the drainage pipe 433. The remaining sand and gravel that meet the particle size requirements are transported upward through the cooperation of the spiral push plate 414 and the rotating chamber 21 and discharged through the discharge port 35. When the soil component detection device on the drainage pipe 433 shows that the soil content in the discharged muddy water exceeds the standard, it means that the sand and gravel discharged from the discharge port 35 have not been cleaned and need to be re-put into the rotating drum 411 for filtration. When the soil component detection device on the drainage pipe 433 shows that the soil content in the discharged muddy water is qualified, it means that the sand and gravel filtration is qualified. At this time, the sand and gravel discharged from the discharge port 35 can be put into construction use; When a certain amount of large-sized sand and gravel is collected in the waste discharge port 42, the waste discharge port 42 is opened to discharge the remaining large-sized sand and gravel. At this time, the discharged large-sized sand and gravel contain very little soil components and can be directly used for other purposes.

[0039] Example 3, reference Figure 1-Figure 8, which is the third embodiment of the present invention. Different from the previous embodiment, the power unit 5 drives the drum 411 to rotate, and includes a servo motor 51 arranged on the tank body 2. Since the servo motor 51 generates power, it is arranged on the upper surface of the tank body 2, which is convenient for maintenance and can prevent sand and water from interfering with the operation of the servo motor 51; an output gear 52 arranged on the servo motor 51, which is used to rotate with the servo motor 51; and an input gear 53 arranged on the waste discharge port 42 to cooperate with the output gear 52, which is used to cooperate with the rotation of the output gear 52, drive the waste discharge port 42 to rotate, thereby driving the drum 411 to rotate, and realize the filtering of sand and gravel.

[0040] The rest of the structure is the same as that of Example 2.

[0041] During use, when water and sand and gravel to be filtered enter the drum 411 through the receiving plate 32, the servo motor 51 is started to drive the output gear 52 to rotate, thereby driving the input gear 53 to rotate. At this time, the waste discharge port 42 rotates, driving the separation component 41 to rotate as a whole, and filtering the sand and gravel in the drum 411.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
