Description

Technical Field

[0001] This utility model relates to the field of sand washing and recycling technology, and in particular to a sand washing and recycling device. Background Technology

[0002] It's called a sand washing machine, mainly used to remove impurities (such as dust) from sand products. Because it mostly uses water washing methods, it's also called a stone washing machine. Here, "stone" more often refers to sand, so it's also called a sand washing machine.

[0003] When a sand washing machine is working, it uses a large amount of water to wash the sand and gravel, thereby separating impurities such as mud from the sand and gravel. During the sand washing process, a lot of fine sand is discharged from the sand washing machine with the water flow, resulting in waste and environmental pollution.

[0004] To avoid the aforementioned problems of fine sand waste and environmental pollution, sand washing machines are typically used in conjunction with recycling devices. These devices recycle and reuse wastewater and separate fine sand from the wastewater. The bucket wheel in the recycling device is a crucial component for separating water and fine sand. Because it constantly rubs against the fine sand, it is a wear part and requires frequent replacement. Currently, the separating buckets in existing bucket wheels are often integrated with the rotor, making replacement quite cumbersome.

[0005] Therefore, this application proposes a sand washing and recovery device for convenient replacement of easily damaged separation buckets. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a sand washing and recycling device to solve the problem of the difficulty in replacing the separating bucket in the bucket wheel mentioned in the prior art.

[0007] To achieve the above and other related objectives, this utility model provides a sand washing and recycling device, including a recycling bin, one end of which is provided with a sedimentation section, and the recycling bin and the sedimentation section are interconnected. The recycling bin is equipped with a conveying unit inside, the sedimentation unit is equipped with a sand-water separation unit inside, and a driving unit is provided on the side of the recycling bin or sedimentation unit. The driving unit drives the conveying unit and the sand-water separation unit to rotate simultaneously. Wastewater discharged from the external sand washing machine enters the interior of the recycling bin and is transported to the interior of the sedimentation section via the conveying section. The sand-water separation section separates the fine sand from the water by rotation and discharges it from the sedimentation section. The sand-water separation unit includes a wheel frame, and detachable fixing plates are provided on both sides of the wheel frame. Several detachable sand-water separation buckets are installed at equal intervals between the two fixing plates.

[0009] Preferably, each of the fixing pieces is formed by splicing multiple arc-shaped metal plates end to end to form a ring, and each arc-shaped metal plate is supported by multiple supporting beams; Each of the arc-shaped metal plates has several separation bucket mounting holes on its outer edge.

[0010] Preferably, the outer surface of all the sand-water separation buckets is fitted with the side of the fixing plate to form a circle, and the fixing plate and the sand-water separation bucket are fixed together by fasteners passing through the installation holes of the separation bucket.

[0011] Preferably, the sand-water separation buckets are in two sets, with the two sets of sand-water separation buckets arranged side by side between two fixed plates, and the two sets of sand-water separation buckets are staggered.

[0012] Preferably, all the supporting beams are provided with a separation bucket mounting plate at their axis, and the adjacent surfaces of the two sets of sand-water separation buckets are attached to the supporting beams and fixed by fasteners.

[0013] Preferably, the sedimentation section includes a sedimentation tank, the sand-water separation section is mounted above the sedimentation tank and extends into the interior of the sedimentation tank, the side of the sedimentation tank is provided with a sand outlet, and the outer surface of the sand outlet is provided with a guide plate. The inner wall of the sand outlet is in contact with the outer surface of the sand-water separation hopper.

[0014] Preferably, the drive unit includes a drive motor, and the output end of the drive motor is provided with a drive shaft. The drive shaft passes through the axis of the wheel frame and the conveyor unit respectively to transmit power to the wheel frame and the conveyor unit.

[0015] Preferably, the conveying unit includes a stirring plate support frame, and the outer surface of the stirring plate support frame is provided with a guide stirring plate; The axis of the stirring plate support frame is sleeved with the drive shaft, and the guide stirring plate extends into the interior of the recovery bin. The guide stirring plate, driven by the drive motor, drives the wastewater to flow into the interior of the sedimentation section.

[0016] Preferably, the stirring plate support frame is composed of a first support rod and a second support rod, which overlap and are fixed together by fasteners.

[0017] As described above, the sand washing and recycling device of this utility model has the following beneficial effects: 1. This utility model sets up a wheel frame and sets fixed plates on both sides of the wheel frame in a detachable manner. Several sand-water separation buckets are set between the fixed plates on both sides and fixed with bolts. When the sand-water separation buckets are worn, they can be replaced by disassembling the corresponding sand-water separation buckets individually, which achieves the effect of convenient maintenance and reduced maintenance costs.

[0018] 2. In this utility model, the fixing plate is made up of multiple arc-shaped metal plates spliced ​​together, and multiple sand-water separation buckets are installed according to the splicing area of ​​the fixing plate.

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0031] Please see Figures 1 to 7 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0032] like Figures 1-4 As shown, this utility model provides a sand washing and recycling device, including a recycling bin 1, a sedimentation section 2 at one end of the recycling bin 1, and supports for both the outer surfaces of the recycling bin 1 and the sedimentation section 2, with the bottom of the recycling bin 1 being higher than the bottom of the sedimentation section 2. The recycling bin 1 and the sedimentation section 2 are interconnected. Wastewater from the sand washing process is discharged into the recycling bin 1, and the wastewater carries the washed sand to the sedimentation section 2.

[0033] The recovery chamber 1 is equipped with a conveying unit 3, and the sedimentation chamber 2 is equipped with a sand-water separation unit 4. A drive unit 5 is located on the side of either the recovery chamber 1 or the sedimentation chamber 2, driving both the conveying unit 3 and the sand-water separation unit 4 to rotate. When the conveying unit 3 rotates, it generates a driving force that propels the wastewater into the sedimentation chamber 2 at an accelerated speed. At this time, the rotating sand-water separation unit 4 carries away both the wastewater and fine sand from the sedimentation chamber 2. The wastewater flows back into the sedimentation chamber 2 through the filter holes and gaps in the sand-water separation unit 4, achieving sand and water separation. The separated fine sand is then discharged outside the equipment for recycling as the sand-water separation unit 4 rotates.

[0034] The sand-water separation unit 4 includes a wheel frame 41 with a circular outer contour that extends into the interior of the sedimentation unit 2. Separable fixing plates 42 are provided on both sides of the wheel frame 41, and several separable sand-water separation hoppers 43 are equidistantly installed between the two fixing plates 42, securing the sand-water separation hoppers 43. The principle of sand-water separation by the sand-water separation hoppers 43 is the same as that of existing devices; therefore, this application will not elaborate on its principle. By arranging several sand-water separation hoppers 43, each hopper is relatively independent. When a sand-water separation hopper 43 becomes worn, the worn hopper can be replaced individually without replacing the entire hopper, thus improving maintenance convenience and reducing maintenance costs.

[0035] like Figure 5 As shown, in some embodiments, the wheel frame 41 of this utility model includes a support shaft cylinder 411, and the outer surface of the support shaft cylinder 411 is provided with inclined braces 412 distributed radially at equal intervals along the support shaft cylinder 411 to form a keel frame. Each inclined brace 412 has a support beam 413 at its end, and both ends of the support beam 413 extend out of the outer surface of the inclined brace 412. Two fixing plates 42 are respectively installed at both ends of the support beam 413 to form a frame that supports and fixes the sand-water separation hopper 43.

[0036] like Figure 4 and Figure 5 As shown in some embodiments, each fixing piece 42 of this invention is composed of multiple arc-shaped metal plates spliced ​​end to end to form a ring, and each arc-shaped metal plate is supported by multiple supporting beams 413. This allows the fixing piece 42 to form multiple areas, so during maintenance, only the corresponding area needs to be disassembled. This effectively reduces the time required for equipment disassembly and the weight of the disassembled equipment, further improving maintenance convenience and efficiency.

[0037] Each arc-shaped metal plate has several separation bucket mounting holes 421 on its outer edge. If the separation bucket mounting holes 421 form a circle with the axis of the support shaft cylinder 411 as the origin, the installed sand-water separation buckets 43 will be distributed in a circular outline along the separation bucket mounting holes 421.

[0038] like Figure 2 and Figure 4 As shown, in some embodiments, the outer surface of all sand-water separation hoppers 43 of this invention is fitted with the side of the fixing plate 42 to form a circle. The fixing plate 42 and the sand-water separation hopper 43 are fixed together by fasteners passing through the separation hopper mounting holes 421. When one or more sand-water separation hoppers 43 are damaged, the metal arc plate at the damaged location can be disassembled individually to replace the damaged sand-water separation hopper 43, further improving the convenience of maintenance.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the sand-water separation buckets 43 of this invention are in two sets, arranged side by side between two fixed plates 42, and staggered between the two sets of sand-water separation buckets 43. When the wheel frame 41 rotates, the two sets of staggered sand-water separation buckets 43 can reduce the interval of digging fine sand, thereby improving the ability and efficiency of separating fine sand.

[0040] like Figure 5 As shown in some embodiments, all the supporting beams 413 of this utility model are provided with a separation bucket mounting plate 414 at their axis. The adjacent surfaces of the two sets of sand-water separation buckets 43 are attached to the supporting beams 413 and fixed by fasteners, so that the sand-water separation buckets 43 on both sides can be disassembled separately, further improving the convenience of maintenance.

[0041] like Figure 1 As shown, in some embodiments, the sedimentation unit 2 of this utility model includes a sedimentation tank 21, and a sand-water separation unit 4 is mounted above the sedimentation tank 21 and extends into the interior of the sedimentation tank 21. This allows for the extraction of wastewater containing fine sand from inside the sedimentation tank 21, separating the fine sand from the wastewater. A sand outlet 22 is provided on the side of the sedimentation tank 21. Washed sand separated by the sand-water separation bucket 43, after being rotated, falls from the opening of the bucket 43 and is discharged from the equipment through the sand outlet 22. A guide plate 23 is provided on the outer surface of the sand outlet 22 to guide the discharged fine sand, allowing it to fall into a subsequent conveyor belt for collection. The inner wall of the sand outlet 22 is fitted to the outer surface of the sand-water separation bucket 43 to prevent the separated fine sand from falling back into the sedimentation tank 21 through the gap between the sand-water separation bucket 43 and the sand outlet 22, thus improving the separation capacity.

[0042] like Figure 1 and Figure 3As shown, in some embodiments, the drive unit 5 of this invention includes a drive motor 51, which is powered externally. A drive shaft 52 is provided at the output end of the drive motor 51, passing through the shafts of the wheel frame 41 and the conveying unit 3. When the drive motor 51 is powered on and started, the drive shaft 52 can drive the wheel frame 41 and the conveying unit 3, thereby causing the conveying unit 3 and the sand-water separation unit 4 to rotate, guiding and separating the wastewater.

[0043] like Figure 6 and Figure 7 As shown, in some embodiments, the conveying unit 3 of this utility model includes a stirring plate support frame 31, and a guide stirring plate 32 is provided on the outer surface of the stirring plate support frame 31. The axis of the stirring plate support frame 31 is sleeved with the drive shaft 52, so that the stirring plate support frame 31 can be driven to rotate after the drive shaft 52 is driven by the drive motor 51. The guide stirring plate 32 extends into the interior of the recovery chamber 1. When the stirring plate support frame 31 rotates, the guide stirring plate 32 rotates with the drive motor 51, thereby driving the wastewater to flow into the interior of the sedimentation unit 2.

[0044] like Figure 7 As shown, in some embodiments, the stirring plate support frame 31 of this utility model is composed of a first support rod 311 and a second support rod 312, with the first support rod 311 and the second support rod 312 alternately arranged on the outer surface of the drive shaft 52 of the stirring plate support frame 31. The first support rod 311 and the second support rod 312 overlap and are fixed together by fasteners, so that the stirring plate support frame 31 can be disassembled in sections to further improve the convenience of maintenance.

[0045] In summary, the sand washing and recycling device of this utility model, by setting a wheel frame 41 and detachably setting fixing plates 42 on both sides of the wheel frame 41, and by setting several sand-water separation buckets 43 between the fixing plates 42 on both sides and fixing them with bolts, when the sand-water separation buckets 43 are worn, they can be replaced by disassembling the corresponding sand-water separation buckets 43 individually, thus achieving the effect of convenient maintenance and reduced maintenance costs.

[0046] This utility model sets the fixing plate 42 to be spliced ​​together by multiple arc-shaped metal plates, and multiple sand-water separation buckets 43 are installed according to the splicing area of ​​the fixing plate 42. Thus, during maintenance, the arc-shaped metal plates in the fixing plate 42 can be disassembled and separated individually for the damaged area, thereby further improving the convenience of maintenance.

[0047] This utility model sets a separation bucket mounting plate 414 at the axis of the supporting beam 413, and fixes the sand-water separation bucket 43 by cooperating with the fixing plate 42 through the separation bucket mounting plate 414. This allows the sand-water separation bucket 43 to be divided into two staggered groups, thereby improving the efficiency of separating sand and water. At the same time, the sand-water separation bucket 43 can be disassembled and replaced on one side during maintenance, improving the convenience of maintenance.

[0048] This utility model uses a first support rod 311 and a second support rod 312 to form a stirring plate support frame 31. When maintaining the conveying part 3, the first support rod 311 and the second support rod 312 can be separated to realize the segmentation of the stirring plate support frame 31, thereby improving the convenience of maintenance and installation of the stirring plate support frame 31.

[0049] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
