[0001] The utility model relates to the technical field of building construction equipment, in particular to a sand sorting device for building construction. Background Art
[0002] Silt is a mixture of solid particles carried by water or waves, that is, a mixture of soil and sand. This silt cannot be used in construction because sand used in construction needs to have edges and corners so that the particles can better hook up with each other to form a solid structure. The inclusion of soil covers the edges and corners of the sand, so equipment is needed to sort the silt.
[0003] In the prior art, mud and sand are added into the sieve body and washed with water, so that the mud is diluted by the water and passes through the sieve body, while smaller particles are left behind by the sieve body. However, the existing problem is that it is difficult for all the mud to be diluted by the water, resulting in partial blockage on the sieve body. Utility Model Content

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0028] Example: Figure 1 As shown, the device for sorting mud and sand for construction disclosed in the present application comprises a sorting box 1, in which a mud and sand temporary retention area 2, a screening area 3 and a mud and water retention area 4 are sequentially arranged from top to bottom. The mud and sand enter the screening area 3 from the mud and sand temporary retention area 2 to complete the sorting of mud and sand. Specifically, the mud in the mud and sand is diluted and taken away through the screening area 3 by water injection and washing, and finally concentrated in the mud and water retention area 4, so that only sand remains in the screening area 3.
[0029] Furthermore, the top of the sorting box 1 is open and optionally provided with a cover, and at least one-third of the portion close to the inlet is the sediment temporary retention area 2, that is, the sediment entering through the inlet of the sorting box 1 temporarily stays in the sediment temporary retention area 2.
[0030] Specifically, the sediment temporary retention area 2 is formed by the partition 21 provided in the sorting box 1 and occupies the space of the sorting box 1 , and the space needs to be at least one third of the entire sorting box 1 .
[0031] A discharge port 22 is provided on the partition 21, so that the sediment in the sediment temporary retention area 2 forms a sediment column 5 in the screening area 3 under the pressure of gravity. Specifically, the partition 21 is funnel-shaped, and the discharge port 22 is provided at the lowest end of the funnel-shaped partition 21. When the discharge port 22 is circular, the formed sediment column 5 is cylindrical. When the discharge port 22 is rectangular, the formed sediment column 5 is square. In this embodiment, the discharge port 22 is preferably rectangular.
[0032] Furthermore, the screening area 3 is formed by at least one-third of the portion between the filter body 31 and the partition 21 provided in the sorting box 1, and at least two nozzles 6 are relatively provided inside the screening area 3, that is, one on each side, and of course, two, three or more on each side can also be provided. The nozzle 6 is used to spray the compressed water form onto the sediment column 5, so that the mud in the sediment column 5 is diluted under the high-pressure water form, so as to complete the dilution of the mud before it contacts the filter body 31, thereby avoiding the dilution of the mud on the filter body 31 and avoiding the local blockage of the mud on the filter body 31 due to the small dilution and flushing surface.
[0033] Furthermore, in the present embodiment, the nozzle 6 is located in the screening area 3 in a first direction (referring to the left and right directions in the figure), and the nozzle 6 is gradually expanded toward one side, so that the water form formed by the gradually expanded nozzle 6 is an outward expansion shape 61, and the length of the silt column 5 formed through the discharge port 22 under the action of the outward expansion shape 61 is A length. Specifically, the length A is less than the height of the screening area 3. Because the silt column 5 cannot continue to extend its extent when the water form is the outward expansion shape 61, and is diluted and dispersed in the intersecting areas of the outward expansion shape 61 water forms on both sides, so that the silt column 5 discharged from the discharge port 22 is approximately only A length, and when diluted and dispersed, it will fall on the filter body 31 in a surface shape that evenly covers the filter body 31.
[0034] In this embodiment, the filter body 31 is in the shape of a flat plate and is located in the screening area 3 along the first direction, and a plurality of filter holes for filtering out sand particles are provided on the filter body 31. That is to say, the diameter of the filter holes on the filter body 31 is smaller than the diameter of the approximately large and small sand particles in the mud and sand, so that the sand particles cannot pass through the filter holes, while the diluted muddy water can pass through the filter holes, allowing the sand particles to be concentrated on the filter body 31.
[0035] In this embodiment, the discharge port 22 is installed with a valve body (not shown in the figure), which can receive an external control signal to open or close the discharge port 22. When the discharge port 22 is opened, a mud column 5 is formed. When the discharge port 22 is closed, the mud and water retention area 4 can be filled to roughly fill the mud and water retention area 4, thereby forming sufficient downward pressure gravity to generate the mud column 5.
[0036] In this embodiment, two suction hoppers 7 are also included, which are relatively arranged in the screening area 3, below the nozzle 6, and angled toward the filter body 31. The suction hopper 7 is configured to absorb the sand particles filtered out of the filter body 31. Specifically, when the discharge port 22 is closed for filling, the sand filtered out of the filter body 31 is removed by the negative pressure suction force provided by the suction hopper 7. Of course, it is also possible to install a sealable sand discharge door on the screening area 3 without the suction hopper 7, and open the door to manually remove the sand with the help of tools.
[0037] Furthermore, the mud and water retention area 4 is formed by at least one quarter of the portion between the filter body 31 and the bottom of the sorting box 1. The mud and water retention area 4 is used for transitional retention of mud and water generated by diluting the mud in the mud and sand. Because the bottom side of the mud and water retention area 4 is connected to a drain outlet, the drain outlet is connected to a filter press (not shown in the figure) through a pipe, and the mud and water in the mud and water retention area 4 needs to be discharged into the filter press through a pipe, and filtered to separate the solid and liquid (the specific principle can be found in the existing filter press, which will not be explained in detail here), and the water obtained by filtration can be used as washing water for diluting the mud in the mud and sand, thereby realizing the recycling of water resources.
[0038] like Figure 2 As shown, the device for separating mud and sand for construction disclosed in the present application includes a structure substantially the same as that of the previous embodiment, for example, a separation box 1, in which a mud and sand temporary retention area 2, a screening area 3 and a mud and water retention area 4 are sequentially arranged from top to bottom, and further structures are provided in each area. The same parts can be referred to the previous embodiment, and no repeated description is made here. However, the difference is:
[0039] At least two nozzles 6 in the second direction (referring to Figure 2 The middle nozzle 6 is relatively arranged in an oblique direction (formed by rotating 30° to 50° downward from the first direction), and is contracted to one side. The water form formed by the contracted nozzle 6 is a columnar shape 62, and the length of the sediment column 5 formed through the discharge port 22 is B length, which is greater than the B length of the sediment column 5 in the previous embodiment, and is equal to the length between the discharge port 22 and the filter body 31 vertically.
[0040] Because the landing point of the silt column 5 and the landing point of the columnar 62 water form are both on the filter plate 1, a part of the filter body 1, such as the middle part, needs to withstand a pressure far greater than that borne by the filter body 1 in the previous embodiment. Therefore, in this embodiment, although the filter body 31 is still in a flat plate shape and is located in the screening area 3 along the first direction, a solid portion 311 is provided in the middle of the filter body 31, and the increased pressure is borne by the solid portion 311. A support member 312 is connected to the solid portion 311 and extends into the mud and water retention area 4, so that the solid portion 311 has high strength and is not easy to sink under the pressure of the landing point of the silt column 5 and the columnar 62 water form, causing deformation of the filter body 1.
[0041] At the same time, the step of diluting the mud in the mud and sand is completed on the solid part 311, and the diluted mud and sand splashes everywhere and still falls on the filter body 31 in a shape of evenly covering the surface of the filter body 31, allowing the muddy water to quickly pass through the filter holes on the filter body 31.
[0042] In this example, the size of the solid portion 311 on the filter body 31 is determined according to actual applications, for example, it may occupy one sixth, one fifth or one quarter of the area of the filter body 31 , and the present disclosure does not impose any limitation on this.
[0043] like Figure 3 Shown and referenced Figure 1 or Figure 2 The present disclosure further includes a conveying pipe 8 connected to the nozzle 6 or the suction hopper 7 in the above embodiment, and the conveying pipe 8 is used to convey water or sand.
[0044] Furthermore, the conveying pipe 8 includes two pipes 81 connected to the nozzle 6 or the suction hopper 7 , a three-way joint 82 disposed between the two pipes 81 , and a flange interface 83 also connected to the three-way joint 82 .
[0045] For example, the flange interface 83 connected to the nozzle 6 is connected to a pump body (not shown in the figure), and the input port of the pump body is connected to the filter press through a pipeline, so that the liquid obtained by the filter press is reused as cleaning water.
[0046] The flange interface 83 connected to the nozzle 6 is connected to a sand suction machine (not shown in the figure), which can absorb sand in a wet state. It mainly includes a high-power vacuum pump, which generates negative pressure suction for absorbing wet sand through workmanship: during the adsorption process, the sorting box 1 is in a sealed state. Specifically, the top inlet of the sorting box 1 is sealed and closed by a baffle cover, and the drain outlet and the filter press remain disconnected.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
