[0040] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.
[0041] Embodiment 1, referring to Figures 1 to 3 , which is the first embodiment of the present invention, and a sand washer for rapid sub-packaging with different particle sizes is proposed.
[0042] In this embodiment, the sand washer specifically includes a frame 1, a sieve drum 2, and a spray pipe 5. The number of sieve drums 2 is several, preferably three in this embodiment, and they are sequentially installed on the frame 1. The sizes of the sieve holes 3 on the three sieve drums 2 are different. When viewed along the material conveying direction, the three sieve drums 2 are a small-hole sieve, a medium-hole sieve, and a large-hole sieve respectively. During use, the material is first put into the small-hole sieve, and at the same time, the small-hole sieve is driven to rotate. As the small-hole sieve rotates, the material rolls inside the sieve drum 2. Water is supplied to the spray pipe 5 by an external water pump, and the water sprays out from the spray holes 6 to wash the rolling stones, achieving all-round cleaning. As the material rolls, the small-grained stones will leak out from the sieve holes 3 of the small-hole sieve, completing the screening of the small-grained materials. As the material gradually moves, it gradually moves into the medium-hole sieve, repeating the operation inside the small-hole sieve to complete the screening of the medium-grained materials. Then the remaining material enters the large-hole sieve to complete the screening of the large-grained materials. Finally, the material remaining after being screened by the three sieve drums 2 is collected for use in other positions with requirements, or this part of the material is crushed through reprocessing to obtain materials with different particle sizes. Through the cooperation of the sieve drum 2 and the spray pipe 5, the classification screening of the material is realized during the cleaning process of the material, shortening the process flow, reducing the screening time, and improving the work efficiency.
[0043] Embodiment Two. Refer to Figures 1 to 3 , which is the second embodiment of the present utility model. On the basis of Embodiment One, in this embodiment, further, a sloping plate 7 is added. The number of sloping plates 7 is several. In this embodiment, one group A preferably has six sloping plates 7, and each sieve drum 2 has several groups A. During use, an external force is applied to drive the sieve drum 2 to rotate, and the sieve drum 2 drives the sloping plate 7 to rotate synchronously. The sloping plate 7 will push the material to move synchronously. During the process of the sloping plate 7 moving from the bottom to the top of the screening chamber 4, the material will fall downward under the influence of its own gravity, realizing the tumbling of the material. At the same time, with the inclined setting of the sloping plate 7, the material is pushed to gradually approach the next sieve drum 2 until the material passes through all the sieve drums 2 to complete the screening. One group B preferably has four spray holes 6, and each spray pipe 5 has several groups B. By setting the number and orientation of the spray holes 6, all-round water spraying in the screening chamber 4 can be realized, washing the stones all-round and improving the cleaning effect.
[0044] The rotation directions of adjacent sieve drums 2 are opposite, which can improve the tumbling effect of the material and at the same time can break up the inherent state of the material, avoiding the problem of incomplete material screening.
[0045] Embodiment Three. Refer to Figures 1 to 3, which is the third embodiment of the present utility model. On the basis of Embodiment 1, this embodiment further adds an outer cylinder 8, an aggregate member 9, a sieve plate 10, and a collection member 11. During use, the outer cylinder 8 is used to limit and collect the material and the water sprayed by the spray pipe 5. The sieved material and impurities enter the aggregate member 9 through the collection port. The aggregate member 9 is used to centrally collect the material and impurities. Then, when the collected material and impurities pass through the sieve plate 10, the impurities enter the collection member 11 through the leakage holes on the sieve plate 10 to complete the collection of impurities, and the remaining material is collected and sent to the next processing step. The sieve plate 10 is used to separate the material and impurities to achieve the collection of the material.
[0046] An outer cylinder 8, an aggregate member 9, a sieve plate 10, and a collection member 11 are provided at each sieve cylinder 2. The material sieved by each sieve cylinder 2 undergoes a secondary separation of the material and impurities once, reducing the impurity content rate in the material and improving the purity of the material.
[0047] Embodiment 4, referring to Figures 1 to 4 , which is the fourth embodiment of the present utility model. On the basis of Embodiment 1, this embodiment further adds a power unit 12. Specifically, the power unit 12 includes a toothed belt 13 and a rotation driver 14. Among them, the rotation driver 14 can be a motor driven by electricity in the prior art. The teeth on the toothed belt 13 are not drawn. With the power output by the rotation driver 14, the toothed belt 13 and the sieve cylinder 2 are driven to rotate. The separate power unit 12 can independently drive a sieve cylinder 2 to rotate independently, facilitating the control of the independent rotation of the sieve cylinder 2.
[0048] Embodiment 5, referring to Figures 1 to 4 , which is the fifth embodiment of the present utility model. On the basis of Embodiment 1, this embodiment further adds a feeding unit 15. Specifically, the feeding unit 15 includes a conveyor belt 16, a diversion plate 17, and side guard plates 18. During use, through the transportation of the conveyor belt 16, the material in the initial state moves onto the diversion plate 17. With the height difference at both ends of the diversion plate 17, an initial movement inertia is given to the material to break up the initial state of the material, facilitating the sieving of the material by the sieve cylinder 2. The side guard plates 18 are used to prevent the material from falling outside the sieve cylinder 2 during movement, ensuring the stability of the material transportation.
[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
