Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a screen mechanism for a split-type dewatering machine. Background Technology

[0002] In the process of garbage sorting, in order to separate different types of garbage, the garbage is often first soaked in water. By utilizing the different buoyancy of materials with different densities, floating plastics, cotton wool, etc. are scooped out. Then, the sand, gravel, non-ferrous metals, etc. that sink to the bottom are dehydrated before proceeding to the next step of separation and recycling. However, in the process of dehydrating the soaked sand, gravel, and non-ferrous metals, the existing dehydrators, which often use centrifugal dehydration, tend to throw the sand and gravel onto the inner wall of the dehydrator. During the dehydration rotation, the sand and gravel move against the inner wall, which greatly increases the probability of direct contact and friction between the sand and gravel and the inner wall of the dehydrator. This results in the inner wall of the dehydrator casing being easily worn by the sand and gravel friction. The casing is usually not an easy part to replace, thus increasing the difficulty of daily maintenance. Utility Model Content

[0003] To address the aforementioned problems, the present invention aims to provide a split-type screen mechanism for a dewatering machine, which minimizes the wear and tear on the inner wall of the dewatering machine casing caused by sand and gravel during the dewatering process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A split-type dewatering machine screen mechanism includes a base, a housing fixed on the base and vertically arranged in the up-down direction, a cover detachably mounted on the top of the housing, a feed inlet mounted on the cover and vertically arranged in the up-down direction of the housing, a discharge outlet located at the lower end of the housing, a rotating dewatering rod located inside the housing below the feed inlet and above it for driving the waste to perform centrifugal motion, a screening component sleeved on the upper part of the rotating dewatering rod and detachably connected to the upper side of the housing for screening out water and fine materials from the waste, and a collection component located inside the housing for collecting the filtered water and fine materials.

[0006] The upper part of the rotating dehydration rod extends out from the top of the machine housing;

[0007] The screening assembly includes a mounting ring detachably disposed on the upper side of the housing and coaxially disposed with the feed inlet, a screening sleeve fixed above the mounting ring, a fixing ring fixed above the screening sleeve, a plurality of filter hole groups arranged at intervals along the vertical height direction of the screening sleeve on the screening plate, and a reinforcing sub-assembly disposed on the outer wall of the screening sleeve to prevent the screening sleeve from bending.

[0008] Each filter group consists of several filter holes arranged at horizontal circumferential intervals at corresponding height positions on the filter plate.

[0009] More preferably, the reinforcing sub-assembly includes several vertical reinforcing bars arranged along the vertical height direction of the screening sleeve and fixed between the mounting ring and the fixing ring at circumferential intervals, as well as transverse reinforcing bars that surround the middle of the outer wall of the screening sleeve and are fixedly connected to each of the vertical reinforcing bars.

[0010] More preferably, the mounting ring is provided with a plurality of first threaded mounting holes arranged at intervals along the circumference, and the upper side of the housing is provided with a plurality of first threaded connecting holes corresponding one to one of the first threaded mounting holes, and each of the first threaded mounting holes and the first threaded connecting holes are detachably connected by a first fastening screw.

[0011] More preferably, the outer edge of the upper side of the cover is provided with a plurality of second threaded mounting holes arranged circumferentially, and the upper side of the housing is provided with a plurality of second threaded connection holes corresponding to each of the second threaded mounting holes. Each of the second threaded mounting holes and the second threaded connection holes are detachably connected by a second fastening screw.

[0012] More preferably, the collection assembly includes a material collection trough located on the upper side of the housing and with its opening facing upward, surrounding the outer wall of the screening sleeve, and a pair of drainage holes located on the front and rear sides of the inner wall of the material collection trough on the side away from the screening sleeve and penetrating the housing.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses multiple screening holes on the screening sleeve to cause some of the sand and gravel to embed and accumulate in the screening holes when the sand and gravel move offline inside the screening sleeve. This allows the remaining sand and gravel moving inside the screening sleeve to directly contact and rub against the sand and gravel accumulated in the screening holes when it moves against the inner wall of the screening sleeve, thereby minimizing the wear of the sand and gravel on the inner wall of the dewatering machine during the dewatering process.

[0015] 2. This utility model uses a first fastening screw and a second fastening screw to detachably connect the housing and the screening sleeve, so that the screening sleeve can be replaced in a timely manner by removing the housing after long-term use.

[0016] 3. This utility model reinforces the screening sleeve by reinforcing the sub-component, reducing the excessive pressure exerted on the inner wall of the screening sleeve during centrifugal motion due to the large weight of sand and gravel, which could lead to deformation and bending of the side wall of the screening sleeve.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a split-type dewatering machine screen mechanism of this embodiment includes a base 1, a housing 2 fixed on the base 1 and vertically arranged in the up-down direction, a cover 3 detachably covered above the housing 2, a feed inlet 4 arranged on the cover 3 and vertically arranged in the up-down direction of the housing 2, a discharge outlet 5 located at the lower end of the housing 2, a rotating dewatering rod 6 located inside the housing 2 below the feed inlet 4 and used to drive the waste to perform centrifugal motion, a screening component 9 sleeved on the upper part of the rotating dewatering rod 6 and detachably connected to the upper side of the housing 2 for screening out water and fine materials from the waste, and a collection component 10 located inside the housing 2 for collecting the filtered water and fine materials.

[0026] The upper part of the rotating dehydration rod 6 extends out from the top of the machine casing 2;

[0027] The screening assembly 9 includes a mounting ring 91 detachably mounted on the upper side of the housing 2 and coaxially arranged with the feed inlet 4, a screening sleeve 92 fixed above the mounting ring 91, a fixing ring 93 fixed above the screening sleeve 92, a plurality of filter hole groups 94 arranged at intervals along the vertical height direction of the screening sleeve 92 on the screening plate, and a reinforcing sub-assembly 95 provided on the outer wall of the screening sleeve 92 to prevent the screening sleeve 92 from bending.

[0028] Each filter hole group 94 includes several filter holes 941 arranged at horizontal circumferential intervals at corresponding height positions on the filter plate.

[0029] When using this product, waste is poured in through the feed inlet 4, allowing it to enter the screening sleeve 92. Affected by the rotation of the upper part of the rotating dewatering rod 6, the waste undergoes centrifugal motion within the screening sleeve 92. Because the diameter of the waste to be screened, such as sand and non-ferrous metals, is relatively large, the water in the waste is flung out through the screening holes 941 during centrifugal motion. Furthermore, during the screening process, some sand and gravel, due to their smaller diameter, accumulate in the screening holes 941. Therefore, when the sand and gravel adhere to the inner wall of the screening sleeve 92 and undergo centrifugal motion, the direct contact and friction between the sand and gravel and the accumulated material in the screening holes 941 reduces the direct contact between the sand and gravel and the inner wall of the screening sleeve 92, thereby reducing wear on the screening sleeve 92.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, the reinforcing sub-assembly 95 includes several vertical reinforcing bars 951 arranged along the vertical height direction of the screening sleeve 92 and spaced apart circumferentially between the mounting ring 91 and the fixing ring 93, and a transverse reinforcing bar 952 surrounding the middle of the outer wall of the screening sleeve 92 and fixedly connected to each of the vertical reinforcing bars 951.

[0031] When this product is in use, because the waste such as sand, gravel and non-ferrous metals that need to be screened is relatively heavy, when it undergoes centrifugal motion in the screening sleeve 92, it adheres to and abuts against the inner wall of the screening sleeve 92, causing the waste pile to exert an outward thrust on the inner wall of the screening sleeve 92. The horizontal reinforcing strip 952 and the vertical reinforcing strip 951 provide support for the side wall of the screening sleeve 92, which prevents the screening sleeve 92 from deforming and bending due to the impact of the waste.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, a plurality of first threaded mounting holes 11 are arranged circumferentially on the mounting ring 91. A plurality of first threaded connecting holes 12 are provided on the upper side of the housing 2 in a one-to-one correspondence with each of the first threaded mounting holes 11. Each of the first threaded mounting holes 11 and the first threaded connecting holes 12 are detachably connected by a first fastening screw 13.

[0033] When using this product, the mounting ring 91 on the screening sleeve 92 is placed on the differential sleeve 7, and each of the first threaded connection holes 12 is aligned with the corresponding first threaded mounting hole 11. Then, the first fastening screw 13 is used to fix and connect them.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the outer edge of the upper side of the cover 3 is provided with a number of second threaded mounting holes 14 arranged circumferentially. The upper side of the housing 2 is provided with a number of second threaded connection holes 15 corresponding to each of the second threaded mounting holes 14. Each of the second threaded mounting holes 14 and the second threaded connection holes 15 are detachably connected by a second fastening screw 16.

[0035] When using this product, align each of the second threaded mounting holes 14 with the corresponding second threaded connecting holes 15, and then tighten each of the second fastening screws 16 to fix the connecting cover 3 and the housing 2.

[0036] like Figure 1 and Figure 5 As shown, the collection assembly 10 includes a material collection trough 101 located on the upper side of the housing 2 and with its opening facing upward, surrounding the outer wall of the screening sleeve 92, and a pair of drainage holes 102 located on the front and rear sides of the inner wall of the material collection trough 101 on the side away from the screening sleeve 92 and penetrating the housing 2.

[0037] When this product is in use, the screened water is thrown out from the screening hole 941 onto the inner wall of the shell 3, and under its own gravity, it flows downward into the collection tank 101. The water in the collection tank 101 is then discharged by inserting a water pumping pipe into the drain hole 102.

[0038] The differential gearbox 8 has a groove 17 extending through the right side of the housing 2 on its lower side. The groove 17 contains a drive pulley 18 that is axially fixedly connected to the drive shaft of the differential gearbox 8. The base 1 has a drive motor 19 whose output shaft is connected to the drive pulley 18 via belt drive on its upper right side.

[0039] The working principle of this device is as follows:

[0040] Step 1: Place the mounting ring 91 on the new screening sleeve 92 onto the differential sleeve 7, align each of the first threaded connection holes 12 with the corresponding first threaded mounting holes 11, and then fix them together with the first fastening screw 13. Next, place the cover 3 on top of the housing 2, align the second threaded connection hole 15 with the corresponding second threaded mounting hole 14, and fix them together with the second fastening screw 16.

[0041] Step 2: Start the drive motor 19, which transmits the rotational power to the drive pulley 18 via the belt, and drives the gears in the differential gearbox 8 to rotate, so that they drive the differential sleeve 7 and the rotating dehydration rod 6 to rotate at different speeds. The rotating dehydration rod 6 rotates at high speed, and the differential sleeve 7 rotates at low speed.

[0042] Step 3: Pour the waste into the feed inlet 4, allowing it to enter the screening sleeve 92. Affected by the rotation of the upper part of the rotating dewatering rod 6, the waste undergoes centrifugal motion within the screening sleeve 92. Since the diameter of the waste to be screened, such as sand and non-ferrous metals, is relatively large, the water in the waste is thrown out through the screening holes 941 during centrifugal motion. During the screening process, some sand and gravel with smaller diameters accumulate in the screening holes 941. Therefore, when the sand and gravel adhere to the inner wall of the screening sleeve 92 and undergo centrifugal motion, the sand and gravel directly contact and rub against the accumulated screening holes 941, thereby reducing the direct contact between the sand and gravel and the inner wall of the screening sleeve 92 and reducing the wear of the screening sleeve 92.

[0043] Step 4: The filtered water is thrown onto the inner wall of the shell 3 and slides down under its own gravity into the collection tank 101. The operator collects the water in the collection tank 101 through the drain holes 102 on both sides. In the subsequent process, the fine sand particles in the water are screened a second time by a filter press.

[0044] Step 5: The dehydrated waste falls from the lower end of the screening sleeve 92 and into the corresponding feed trough 71 on the differential sleeve 7, and is discharged from the bottom discharge port 5.

[0045] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
