Description

Technical Field

[0001] This utility model relates to the field of vibrating screen plate technology, specifically to a novel urethane screen plate. Background Technology

[0002] In modern industrial production, vibrating screens are used as key screening equipment in many industries such as mining, building materials processing, chemicals, and food.

[0003] Currently, commonly available screen plates have significant shortcomings in many aspects. During rainy season production, even if the screen plate itself is intact, frequent clogging and surface crusting occur, greatly reducing the effectiveness of the screening process. From the perspective of screen hole structure, existing screen designs mainly include two types: conical screen holes and straight holes. While conical screen holes have a larger inlet and a smaller outlet, which facilitates material passage to some extent, dust still easily adheres to the inner wall of the screen holes, leading to clogging problems. Straight-hole screens experience even more severe clogging issues.

[0004] The problems exposed by ordinary material screen plates in practical applications not only greatly increase the workload of cleaning, but also significantly extend the downtime for equipment washing and maintenance, and correspondingly reduce the uptime, resulting in a significant increase in labor costs. Moreover, the wastewater and mud generated from washing the screen plates flow freely, causing serious pollution to the production environment, which is inconsistent with the modern industrial green and environmentally friendly development concept.

[0005] Therefore, it is urgent to develop a new type of screen plate that can effectively solve the problem of clogging, improve screening efficiency, and reduce maintenance costs. Utility Model Content

[0006] The purpose of this invention is to provide a novel urethane sieve plate, aiming to overcome the defects of existing sieve plates such as clogging and low screening efficiency, thereby solving the technical problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel urethane sieve plate, comprising a sieve mesh and a support connection assembly; the sieve mesh is used for material screening and is fitted onto the main frame of the support connection assembly; the support connection assembly comprises a main frame and a connecting base, the main frame being detachably mounted on the connecting base, and the connecting base being fixed to a vibrating screen, providing structural support for the sieve plate and connection to the vibrating screen;

[0008] The screen is provided with screen holes arranged linearly in the transverse and longitudinal directions. The upper surface of the screen holes is an oblong hole. The structure of the screen holes is such that the upper hole diameter is smaller than the lower hole diameter, and the cross-section of the screen holes is a cone shape with a smaller upper part and a larger lower part.

[0009] Furthermore, the main frame is made of steel and includes an outer frame and multiple crossbeams. The crossbeams divide the interior of the outer frame into several equal parts, and a screen is attached to each part.

[0010] Furthermore, the lower part of the main frame is provided with a connecting part, and the connecting part is provided with arc-shaped grooves on both sides along the length direction of the main frame. The arc-shaped grooves are used to cooperate with the connecting base to achieve a detachable connection.

[0011] Furthermore, the connecting base includes a fixed track end and a movable locking end. The fixed track end is provided with a fixed track, the cross-section of which has an arc-shaped protrusion for engaging with the arc-shaped groove to limit one side of the main frame. The movable locking end is provided with a connecting rod buckle and a movable track. A slide is provided on the side of the movable locking end near the main frame, and the movable track is disposed in the slide. The side of the movable track near the main frame has an arc-shaped protrusion, the size and shape of which match the arc-shaped groove.

[0012] Several connecting rod buckles are provided on the side wall of the movable locking end. The telescopic end of the connecting rod buckle is connected to the movable track. The connecting rod buckle drives the movable track to insert into and lock into the arc-shaped groove, limiting the other side of the main frame and ensuring that the main frame is stably installed on the connecting base.

[0013] Furthermore, the connecting rod buckle includes a mounting base, a telescopic rod, a connecting rod, and a handle; the mounting base is mounted on the movable snap-fit ​​end, and the mounting base has a guide groove; the middle part of the telescopic rod passes through the mounting base and is slidably connected to the guide groove on the mounting base; one side of the telescopic rod is connected to the movable track, and the other side is hinged to the handle; the handle has an L-shaped structure; the handle is provided with a first hinge point and a second hinge point; the front end of the handle is hinged to the tail of the telescopic rod at the first hinge point; one end of the connecting rod is hinged to the mounting base, and the other end is hinged to the front end of the handle at the second hinge point.

[0014] Furthermore, the movable latching end also includes a limiting slider, which is disposed on the side of the connecting rod buckle; the movable latching end is provided with a horizontal dovetail groove, and the corresponding limiting slider is provided with a matching dovetail slider; the limiting slider and the movable latching end are slidably connected through the cooperation of the dovetail groove and the dovetail slider; the limiting slider is provided with a limiting groove.

[0015] Furthermore, it also includes an auxiliary screen cleaning component; the auxiliary screen cleaning component is a vibrating ball suspended above the screen.

[0016] Furthermore, the screen is made of carbamate.

[0017] Beneficial effects

[0018] This invention uses high-resilience polyurethane material to make the screen. The screen holes adopt a conical design with a smaller top and a larger bottom, combined with a reasonable screen hole spacing, reducing material clogging and allowing material to pass through the screen plate quickly. This significantly improves screening efficiency and effectively enhances production efficiency.

[0019] This invention facilitates installation, disassembly, and replacement: the screen plate consists of a screen mesh, a main frame, and a connecting base. The screen mesh is fitted onto the main frame, which is detachably mounted on the connecting base, which is then fixed to the vibrating screen. This modular and detachable structural design makes the screen plate easy to install and accurately positioned. When disassembling or replacing the screen mesh or other components, no complicated tools or procedures are required, significantly reducing equipment downtime and improving equipment utilization.

[0020] Because the sieve holes are less prone to clogging, this invention reduces the frequency of sieve plate cleaning, lowers the workload of cleaning personnel, and reduces equipment maintenance costs. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To achieve the above objectives, this utility model provides the following technical solution, such as... Figure 1-8 As shown, a novel urethane sieve plate includes a sieve 1 and a support connection assembly 2; the sieve 1 is used for material screening and is fitted onto the main frame 3 of the support connection assembly 2; the support connection assembly 2 includes the main frame 3 and a connecting base 4, the main frame 3 is detachably installed on the connecting base 4, and the connecting base 4 is fixed on the vibrating screen to provide structural support for the sieve plate and connection with the vibrating screen.

[0034] like Figure 8 The screen 1 shown has screen holes 5 arranged linearly in the transverse and longitudinal directions. The upper surface of the screen holes 5 is an oblong shape, and the structure of the screen holes 5 is such that the diameter of the upper holes is smaller than that of the lower holes. The cross-section of the screen holes 5 is a cone shape with a smaller upper diameter and a larger lower diameter. The screen holes 5 are 6 mm wide and 30 mm long. The spacing of the screen holes 5 in the width direction is 5.5 mm, and the spacing of the screen holes 5 in the length direction is 15 mm. The screen 1 is rectangular in shape, with a length of 256 mm and a width of 145 mm.

[0035] Furthermore, such as Figure 1-2 As shown, the main frame 3 is made of steel to provide the installation base for the screen 1. It includes an outer frame and multiple crossbeams. The multiple crossbeams divide the interior of the outer frame into several parts, and a screen 1 is snapped onto each part. The outer frame of the main frame 3 is 1000mm long, 300mm wide, and 40mm thick. The crossbeams are 18mm wide.

[0036] Furthermore, such as Figure 1-5 As shown, the lower part of the main frame 3 is provided with a connecting part, and the two sides of the connecting part are provided with arc-shaped grooves 6 with a radius of 11mm along the length direction of the main frame 3, which are used to cooperate with the connecting base 4 to achieve detachable connection.

[0037] Furthermore, the connecting base 4 includes a fixed track end 401 and a movable locking end 402. The fixed track end 401 is provided with a fixed track, the cross-section of which has an arc-shaped protrusion, used to cooperate with the arc-shaped groove 6 to limit one side of the main frame 3. The movable locking end 402 is provided with a connecting rod buckle 7 and a movable track 8. A slide is opened on the side of the movable locking end 402 near the main frame 3, and the movable track 8 is set in the slide. The side of the movable track 8 near the main frame 3 has an arc-shaped protrusion, the size and shape of which are matched with the arc-shaped groove 6.

[0038] Several connecting rod latches 7 are located on the side wall of the movable locking end 402. The telescopic end of the connecting rod latches 7 is connected to the movable rail 8. The connecting rod latches 7 drive the movable rail 8 to insert and lock into the arc-shaped groove 6, limiting the other side of the main frame 3 and ensuring that the main frame 3 is stably installed on the connecting base 4. The connecting base 4 is a rectangular frame structure. The front and rear sides of the connecting base 4 are the fixed rail end 401 and the movable locking end 402, and the left and right sides are the connecting plates.

[0039] The front and rear sides of the main frame 3 are clamped and fixed by the fixed track end 401 and the movable snap-fit ​​end 402, and the left and right sides of the main frame 3 are snapped onto the inner walls of the left and right connecting plates of the connecting base 4.

[0040] Furthermore, such as Figure 5-7 As shown, the linkage buckle 7 includes a mounting base 701, a telescopic rod 702, a connecting rod 703, and a handle 704. The mounting base 701 is mounted on the movable snap-fit ​​end 402 and has a guide groove. The middle part of the telescopic rod 702 passes through the mounting base 701 and is slidably connected to the guide groove on the mounting base 701. One side of the telescopic rod 702 is connected to the movable track 8, and the other side is hinged to the handle 704. The handle 704 has an L-shaped structure. The handle 704 has a first hinge point 705 and a second hinge point 706. The front end of the handle 704 is hinged to the tail end of the telescopic rod 702 at the first hinge point 705. One end of the connecting rod 703 is hinged to the mounting base 701, and the other end is hinged to the front end of the handle 704 at the second hinge point 706.

[0041] Initially, the handle 704 is in a horizontal position, and the telescopic rod 702 is retracted under the action of the handle 704. Pressing the handle 704 downwards until it is in a vertical position causes the front end of the handle 704 to push the telescopic rod 702 forward at the first hinge point 705, while simultaneously rotating the handle 704 around the second hinge point 706. The connecting rod latch 7, operated by the handle 704, extends or retracts the telescopic rod 702, thereby controlling the movable track 8 to insert into or disengage from the arc-shaped groove 6 of the main frame 3, achieving a detachable connection between the main frame 3 and the connecting base 4.

[0042] Furthermore, the movable locking end 402 also includes a limiting slider 9, which is disposed on the side of the connecting rod latch 7. The movable locking end 402 is provided with a horizontal dovetail groove, and the corresponding limiting slider 9 is provided with a matching dovetail slider. The limiting slider 9 and the movable locking end 402 are slidably connected through the cooperation of the dovetail groove and the dovetail slider. The limiting slider 9 is provided with a limiting groove 10. When the limiting slider 9 moves to the vicinity of the connecting rod latch 7, the limiting groove 10 on the limiting slider 9 locks and limits the handle 704 of the connecting rod latch 7, which is in the extended state, so that the handle 704 remains stationary. Locking the connecting rod latch 7 keeps it in the extended state, that is, the movable locking end 402 is always in the locked state, preventing the movable locking end from being loosened due to vibration during operation. The limit slider 9 is also equipped with a clamping bolt 11, which passes through the limit slider 9 and presses against the bottom wall of the dovetail groove, locking the limit slider 9 and the movable locking end 402 together to prevent loosening. The limit slider 9 is used to lock the connecting rod latch 7 handle 704 in the extended state to prevent it from loosening due to working vibration and to ensure a stable connection.

[0043] Furthermore, it also includes an auxiliary screen cleaning component; the auxiliary screen cleaning component is a vibrating ball installed above the screen 1 via a suspension device. When the screen 1 vibrates, the vibrating ball cleans the material residue on the screen 1 through its own vibration and elasticity, preventing the screen holes 5 from clogging. The vibrating ball is purchased equipment, and the use of vibrating balls on the screen 1 is prior art. Its specific principle and structure will not be described in this application.

[0044] Furthermore, the material used to make screen 1 is urethane. Urethane is an industrial screen material with advantages such as good wear resistance, long service life, and low specific gravity, making it lighter than metal screens of the same size. Due to the secondary vibration characteristics of urethane screens, they have a self-cleaning effect, are less prone to clogging of screen holes 5, and improve screening efficiency.

[0045] Working principle

[0046] After the vibrating screen is started, the vibration is transmitted to the main frame 3 through the connecting base 4, which in turn drives the screen 1 to vibrate. The material is placed on the screen 1 and disperses and moves in all directions under the action of vibration.

[0047] The upper surface of the sieve hole 5 is an elongated oval shape without sharp corners, which reduces the adhesion and accumulation of material dust at the sharp corners compared to diamond and square sieve holes 5. The sieve hole 5 has a conical structure that is smaller at the top and larger at the bottom. Under the action of gravity, the material and powder will not accumulate on the side wall of the sieve hole 5, but will fall directly down, effectively preventing the sieve hole 5 from clogging and improving the material separation efficiency.

[0048] Screen 1 is made of high-resilience polyurethane material, and its excellent resilience plays a key role in screening. The secondary vibration characteristics of the high-resilience screen 1 give the screen plate a self-cleaning effect. During vibration, the screen plate deforms slightly, shaking off fine particles adhering to the screen holes 5, ensuring a continuous and efficient screening process. At the same time, the vibrating balls suspended above the screen plate bounce along with the screen 1 when it vibrates. With their own vibration and elasticity, they impact the material residue on the screen 1, further cleaning the screen 1 and preventing the screen holes 5 from clogging. This, combined with the screen plate's self-cleaning function, improves the anti-clogging performance.

[0049] In use, first fix the connecting base 4 onto the vibrating screen, ensuring that the fixed track end 401 is firmly installed and its arc-shaped protrusion structure precisely matches the corresponding position of the vibrating screen. Next, align one side of the main frame 3 with the arc-shaped protrusion structure of the fixed track end 401 and snap it in to achieve lateral positioning. Then, operate the connecting rod latch 7 of the movable latch end 402, press down the L-shaped handle 704, and the handle 704 drives the telescopic rod 702 to extend, so that the movable track 8 is inserted into the arc-shaped groove 6 on the other side of the main frame 3, completing the initial connection. Then move the limiting slider 9 so that it slides to the vicinity of the connecting rod latch 7 through the cooperation of the dovetail groove and the dovetail slider, and use the limiting groove 10 to lock the handle 704 of the extended connecting rod latch 7. Finally, tighten the clamping bolt 11 on the limiting slider 9 to snap the screen 1 into the corresponding position of the main frame 3, completing the installation.

[0050] When the screen plate needs maintenance or replacement, first loosen the clamping bolt 11 on the limit slider 9 to unlock the limit slider 9 from the handle 704 of the connecting rod latch 7. Then, lift the handle 704 of the connecting rod latch 7 upwards to retract the telescopic rod 702, causing the movable track 8 to disengage from the arc-shaped groove 6 of the main frame 3, thereby allowing the main frame 3 to be removed from the connecting base 4. Next, remove the screen 1 from the main frame 3 for cleaning or replacement.

[0051] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
