[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To address the technical problem of powder material spilling out due to damage to the corrugated hose wall caused by the vibration of the vibrating screen 200, resulting in material waste, this invention provides an anti-overflow device for vibrating screens. This device extends the discharge end of the dryer 100 to the feed cylinder 300 via a guide cylinder 400, allowing material to enter the feed end of the screen 200 from the dryer 100's discharge end. Simultaneously, a sealing element 500 is installed between the inner circumferential wall of the feed cylinder 300 and the outer circumferential wall of the screen 200. The sealing element 500 remains in contact with the outer circumferential wall of the guide cylinder 400 during vibration of the screen 200 relative to the dryer 100, preventing material spillage and improving the working environment in the production workshop.

[0029] Please see Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the structure of an anti-overflow device for a vibrating screen in one embodiment of the present invention. The anti-overflow device for the vibrating screen is configured to connect a dryer 100 and a screen 200. The dryer 100 has a discharge end, and the screen 200 has a feed end. The device includes a feed cylinder 300, a guide cylinder 400, and a sealing element 500. The feed cylinder 300 is hollow inside, and its two ends are respectively provided with a first inlet and a first outlet communicating with its interior. The first outlet is connected to the feed end of the screen 200. The guide cylinder 400 is hollow inside, and its two ends are respectively provided with a second inlet and a second outlet communicating with its interior. The second inlet is connected to the discharge end of the dryer 100, and the second outlet is inserted into the first inlet. The sealing element 500 is disposed between the circumferential inner wall of the feed cylinder 300 and the circumferential outer wall of the guide cylinder 400 to seal the gap between the feed cylinder 300 and the guide cylinder 400.

[0030] In this device, compared with the prior art, by extending the discharge end of the dryer 100 to the feed cylinder 300 through the guide cylinder 400, the material can enter the feed end of the screening machine 200 from the discharge end of the dryer 100. At the same time, a sealing element 500 is provided between the circumferential inner wall of the feed cylinder 300 and the circumferential outer wall of the cylinder. The sealing element 500 can always abut against the circumferential outer wall of the guide cylinder 400 when the screening machine 200 vibrates relative to the dryer 100, which can prevent material spillage, improve the working environment of the production workshop, and solve the technical problem in the prior art that the vibration of the vibrating screening machine 200 causes damage to the corrugated hose wall, resulting in powder material spilling out along the damaged area, thus causing material waste.

[0031] Furthermore, the dryer 100 here is a disc dryer 100 that is common and readily available in the market. For reference, please refer to Chinese Utility Model Patent No. CN221197835U, entitled "A Disc Dryer 100 with Automatic Oxygen Content Control". The sieve 200 is a vibrating sieve 200 that is common and readily available in the market. For reference, please refer to Chinese Utility Model Patent No. CN219003779U, entitled "A Device for Removing Magnetic Foreign Objects". The disc dryer 100 and the vibrating sieve 200 are both conventional settings known to those skilled in the art, and will not be described in detail here.

[0032] In this embodiment, as Figures 1 to 3 As shown, the outer diameter of the guide cylinder 400 gradually decreases along the direction close to the feed cylinder 300.

[0033] In order to facilitate the insertion of the guide cylinder 400 into the feed cylinder 300 and reduce material spillage, the outer diameter of the guide cylinder 400 gradually decreases in the direction close to the feed cylinder 300.

[0034] Furthermore, both the feed cylinder 300 and the guide cylinder 400 are common and readily available stainless steel cylinders on the market. Specifically, the feed cylinder 300 is cylindrical and the guide cylinder 400 is funnel-shaped, which will not be described in detail here.

[0035] In this embodiment, the seal 500 is annular and has an elastic structure.

[0036] To enhance the sealing performance between the seal 500 and the circumferential outer wall of the guide cylinder 400, the seal is annular, which can enclose the guide cylinder 400. At the same time, the seal 500 is an elastic structure, which can increase the fit between the seal 500 and the circumferential outer wall of the guide cylinder 400 and improve the sealing effect.

[0037] Furthermore, the sealing material here is a common and readily available polymeric elastomer material, such as thermoplastic polyurethane (TPU), or a rubber material, such as natural rubber (NR) or styrene-butadiene rubber (SBR).

[0038] In some embodiments, the seal 500 may also be a composite material, such as an inflatable elastomer or spring steel.

[0039] Furthermore, the sealing element 500 is an annular airbag structure. The annular airbag is connected to the inflation / deflation device, and a pressure detection unit is installed inside the annular airbag. When the feed cylinder 300 compresses the guide cylinder 400 due to the vibration of the vibrating screen 200, the pressure detection unit detects that the pressure inside the annular airbag exceeds the preset value. The inflation / deflation device then discharges the gas inside the annular airbag. When the compression is removed, the pressure detection unit detects that the pressure inside the annular airbag is lower than the preset value. The inflation / deflation device then replenishes the gas inside the annular airbag. During the inflation / deflation process, the outer wall of the annular airbag is always in contact with the circumferential outer wall of the guide cylinder 400. This will not be elaborated further here.

[0040] In one embodiment, please refer to Figure 3 The sealing element 500 has a connecting end and an abutting end 510. The connecting end of the sealing element 500 is fixedly connected to the circumferential inner wall of the feed cylinder 300. The abutting end 510 of the sealing element 500 is set relative to the guide cylinder 400 and always moves against the circumferential outer wall of the guide cylinder 400. The cross-section of the abutting end 510 is arc-shaped.

[0041] The connecting end of the seal 500 is used to connect with the circumferential inner wall of the feed cylinder 300. The cross-section of the abutting end 510 of the seal 500 is arc-shaped, which can enhance the fit with the circumferential outer wall of the guide cylinder 400, thereby improving the sealing effect.

[0042] In this embodiment, as Figure 1 , Figure 2 As shown, the anti-overflow device for the vibrating screen also includes a buffer assembly 600, which is disposed on the feed cylinder 300 and the guide cylinder 400 to limit the separation of the abutting end 510 of the seal 500 from the circumferential outer wall of the guide cylinder 400.

[0043] By connecting the buffer assembly 600 to the feed cylinder 300 and the guide cylinder 400 respectively, the seal 500 can be prevented from separating from the circumferential outer wall of the guide cylinder 400, thereby improving the sealing effect.

[0044] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The buffer assembly 600 also includes a first fixing ring 610, a second fixing ring 620, and at least one buffer member 630. The first fixing ring 610 is fixedly sleeved on the feed cylinder 300, and the second fixing ring 620 is fixedly sleeved on the guide cylinder 400. The two ends of the buffer member 630 are respectively connected to the first fixing ring 610 and the second fixing ring 620, and are used to drive the first fixing ring 610 to slide relative to the second fixing ring 620 and then automatically reset.

[0045] At least one buffer 630 is connected to the feed cylinder 300 and the guide cylinder 400 at both ends via a first fixing ring 610 and a second fixing ring 620, respectively.

[0046] Furthermore, the first fixing ring 610 and the second fixing ring 620 here are flanges that are common and easy to purchase on the market. The first fixing ring 610 and the second fixing ring 620 are connected to the feed cylinder 300 and the guide cylinder 400 respectively by welding. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0047] In one embodiment, please refer to Figure 4 The buffer 630 includes a fixed base 631 and an elastic part 632. One end of the fixed base 631 is connected to the second fixed ring 620, and one end of the elastic part 632 is connected to the first fixed ring 610 and the other end is connected to the other end of the fixed base 631.

[0048] The fixed base 631 is provided to connect the elastic part 632 and the second fixed ring 620. By providing the fixed base 631, the length of the elastic part 632 can be reduced, production costs can be reduced, and the stability of the device operation can be improved.

[0049] Furthermore, the elastic part 632 here is a spring that is common in the market and easy to purchase. It can also be an elastic block or an elastic sheet. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0050] In one embodiment, please refer to Figure 4 The fixed base 631 has a guide hole, and the buffer 630 also includes a guide rod 633, one end of which is connected to the first fixed ring 610 and the other end is slidably inserted into the guide hole.

[0051] The guide rod 633 is slidably inserted into the guide hole of the fixed base 631 to realize the connection and guidance of the elastic part 632 relative to the fixed base 631 for compression or extension, which can improve the stability of the device operation.

[0052] In one embodiment, please refer to Figure 4 The buffer 630 also includes a piston head 634, which is built into the guide hole and fixedly connected to the other end of the guide rod 633. The circumferential sidewall of the piston head 634 is in sealing contact with the circumferential inner wall of the guide hole.

[0053] The circumferential sidewall of the piston head 634 is sealed against the circumferential inner wall of the guide hole. As the piston head 634 slides relative to the fixed seat 631 with the guide rod 633, it can change the air in the compressed fixed volume, thereby forming a buffer against vibration and improving the stability of the device operation.

[0054] Furthermore, the piston head 634 here is made of a common and readily available rubber material, which is a conventional setting known to those skilled in the art and will not be described in detail here.

[0055] In this embodiment, as Figure 1 , Figure 2 As shown, the buffer assembly 600 has multiple buffer components 630, and multiple fixing seats 631 are evenly arranged along the circumference of the guide cylinder 400 and are respectively connected to the second fixing ring 620.

[0056] Multiple buffer components 630 are evenly arranged along the circumference of the feed cylinder 400, which can improve the stability of the device operation and thus effectively reduce the spillage of materials.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0058] The feed end of the screening machine 200 is connected to the first outlet of the feed cylinder 300, and the discharge end of the dryer 100 is connected to the second inlet of the guide cylinder 400. The second inlet of the guide cylinder 400 can be inserted into the first inlet of the feed cylinder 300. The sealing element 500 is disposed between the circumferential inner wall of the feed cylinder 300 and the circumferential outer wall of the guide cylinder 400. Compared with the prior art, by extending the discharge end of the dryer 100 to the feed cylinder 300 through the guide cylinder 400, the material can enter the feed end of the screening machine 200 from the discharge end of the dryer 100. At the same time, a sealing element 500 is also provided between the circumferential inner wall of the feed cylinder 300 and the circumferential outer wall of the cylinder. The sealing element 500 can always abut against the circumferential outer wall of the guide cylinder 400 when the screening machine 200 vibrates relative to the dryer 100, which can prevent material spillage and improve the working environment of the production workshop.

[0059] In the specific working process of this utility model, when in use, the material enters the guide cylinder 400 through the discharge end of the dryer 100, and then enters the feed end of the screening machine 200 through the feed cylinder 300. The screening machine 200 will drive the feed cylinder 300 to vibrate relative to the guide cylinder 400. During the relative vibration, the sealing element 500 can always abut against the circumferential outer wall of the guide cylinder 400 to prevent the material from overflowing along the gap between the circumferential inner wall of the feed cylinder 300 and the circumferential outer wall of the cylinder.

[0060] Furthermore, during relative vibration, the elastic part 632 can generate an elastic restoring force that drives the guide rod 633 to slide relative to the fixed seat 631 and automatically reset. At the same time, the piston head 634 can form a buffering force after sliding with the guide rod 633 relative to the fixed seat 631, effectively ensuring that the seal 500 can always abut against the circumferential outer wall of the guide cylinder 400, thereby preventing material spillage.

[0061] This application, through the aforementioned structure, can solve the technical problem in the prior art where the vibration of the vibrating screen 200 causes damage to the wall of the corrugated hose, resulting in the spillage of powder material along the damaged area, thus leading to material waste.

[0062] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
