Description

Technical Field

[0001] The utility model belongs to the technical field of screening equipment, and particularly relates to a modular polyurethane sieve plate. Background Art

[0002] The polyurethane sieve plate is a net-shaped product made of polyurethane. It has the advantages of good abrasion resistance, long service life, not easy to be damaged, low cost, good moisture resistance, corrosion resistance, non-flammability, good vibration absorption, easy to clean, energy conservation and environmental protection, etc. Therefore, it is widely used in enterprises such as coal washing plants, coking plants, mines, power plants, dredging companies, metallurgy, petroleum, petrochemical, etc. The modular polyurethane sieve plate is more flexible to use than the ordinary polyurethane sieve plate and can be assembled according to actual needs to adapt to different screening requirements. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with the publication number CN204486258U discloses an assembly structure of a polyurethane sieve plate. The polyurethane sieve plate is fixedly connected to the main beam through polyurethane rivets; the upper part of the polyurethane rivet is provided with a cylindrical nail cap that is in counterbore fit with the rivet hole on the polyurethane sieve plate, and the upper end face of the nail cap is flush with the upper surface of the polyurethane sieve plate; a rectangular ring groove that is in fit with the rivet hole on the main beam is arranged on the lower cylindrical surface of the nail body of the polyurethane rivet; a chamfer is arranged at the lower end of the nail body of the polyurethane rivet. When installing the modular polyurethane sieve plate, it is usually necessary to use a main beam, etc. to splice between multiple polyurethane sieve plates to adjust the screening area. However, since the polyurethane sieve plate needs to screen materials, the contact area between the connecting structures such as the main beam and each polyurethane sieve plate is small. When the materials to be screened are large, or the vibration frequency and amplitude are large, the connecting position is more likely to generate gaps when being vibrated, which may cause fine particles to enter the gaps and rub between the sieve plate and the connecting structure. Long-term friction will shorten the service life of the sieve plate, etc.;

[0004] 2. When connecting modular polyurethane sieve plates, it is often necessary to use rivets, bolts, etc. for stable connection. However, when connecting a large number of modular sieve plates, the connection and disconnection operations of rivets, bolts, etc. are time-consuming and laborious. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a modular polyurethane sieve plate, which solves the problems that in actual use of the modular polyurethane sieve plate, due to the small contact area at the connection of the sieve plates, the connection position is likely to generate gaps when being vibrated, which may cause fine particles to enter the gaps, and long-term friction will shorten the service life of the sieve plate, etc., and when connecting a large number of modular sieve plates, the connection and disconnection operations of rivets, bolts, etc. are time-consuming and laborious through the first support frame, the connecting frame and the connecting plate.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0007] The present utility model is a modular polyurethane sieve plate, including a first support frame, a connecting frame and a connecting plate. A polyurethane sieve plate main body is clamped through the center of the top of the first support frame. A second support frame is arranged at the bottom edge of the first support frame. A connecting frame is inserted between the first support frame and the second support frame. One side of the connecting frame is attached to the bottom of the polyurethane sieve plate main body. A connecting plate is attached to one side of the top of the first support frame. A plurality of connecting insertion rods are welded and fixed to the bottom of the connecting plate. An adsorption insertion rod is inserted through one side of the plurality of connecting insertion rods.

[0008] When assembling the modular polyurethane sieve plate, according to needs, the connecting frame is inserted between two first support frames and the second support frame. The connecting insertion rods penetrate through the first support frame, the connecting frame and the second support frame, and the adsorption insertion rod penetrates through one side of the plurality of connecting insertion rods. Then, a permanent magnet is inserted into one end of the adsorption insertion rod to complete the connection of two modular polyurethane sieve plates. The operation is simple and convenient. And when disassembling, just pull out the permanent magnet, the adsorption insertion rod and the connecting insertion rod in sequence, and the connection positioning between two first support frames and a connecting frame can be quickly released, reducing the labor intensity of the staff. When screening materials through a plurality of modular polyurethane sieve plates, the materials fall onto the surface of the first support frame and the screening operation of the materials is carried out through the polyurethane sieve plate main body. The connecting frame can increase the connection area between two first support frames, avoid the bending of the first support frame under high-frequency vibration and other conditions, reduce the probability of fine particles entering the gap between two first support frames, and the connecting frame can use shock-absorbing materials, which can further reduce the damage caused by vibration to the modular polyurethane sieve plate and extend the service life of the modular polyurethane sieve plate.

[0009] Further, limit blocks are welded and fixed around the bottom of the first support frame. A plurality of the limit blocks are located outside the polyurethane sieve plate main body. The second support frame is welded and fixed to the bottom sides of the plurality of limit blocks. A plurality of first connection holes are penetrated and opened around the tops of the first support frame and the second support frame. The plurality of connecting insertion rods are inserted through the tops of the first connection holes of the first support frame and the second support frame.

[0010] The inserted connecting frame can be limited through the limit blocks and the second support frame, improving the convenience of inserting the connecting frame. And at the same time, four connecting frames can be inserted around the first support frame, enabling the splicing between a plurality of first support frames and improving the flexibility of using the modular polyurethane sieve plate.

[0011] Furthermore, a plurality of material through holes are formed on both sides of the top of the connecting frame, the material through holes are attached to the bottom of the polyurethane sieve plate body, a plurality of second connecting holes are formed in the center of the top of the connecting frame, the two ends of the connecting frame are attached to one side of the limit block, and the connecting rod is inserted into the top of the second connecting hole;

[0012] When the material is screened by multiple modular polyurethane sieve plates, the material falls onto the surface of the first support frame and is screened by the polyurethane sieve plate body. The material can be screened smoothly through the material through the material through the material through-port, and the connection area between the two first support frames can be increased through the connecting frame to avoid bending of the first support frame under high-frequency vibration and the like, thereby reducing the probability of fine particles entering the gap between the two first support frames. The connecting frame can use shock-absorbing materials, which can further reduce the damage caused by vibration to the modular polyurethane sieve plate and extend the service life of the modular polyurethane sieve plate.

[0013] Furthermore, a socket is formed through one side of the outer peripheral surface of the plurality of connecting rods, a first limit plate is welded and fixed to one end of the adsorption rod, the adsorption rod is inserted through one side of the plurality of sockets, the first limit plate is attached to one side of a connecting rod, and the adsorption rod is attached to the bottom of the second support frame;

[0014] When connecting the two first support frames, the connecting frame is inserted between the two first support frames and the second support frames, and the connecting rods are passed through the first support frames, the connecting frame and the second support frames. The multiple connecting rods at the bottom of a connecting plate can be positioned at multiple points to improve loading and unloading efficiency. The adsorption rod is then passed through one side of the multiple connecting rods, and finally the permanent magnet is inserted into one end of the adsorption rod to complete the connection of the two modular polyurethane sieve plates. The operation is simple and convenient.

[0015] Furthermore, the adsorption plug rod has a limiting slot at the other end relative to the first limiting plate, a permanent magnet is inserted into the limiting slot, a second limiting plate is fixedly connected to one side of the permanent magnet, and the second limiting plate is attached to one side of a connecting plug rod;

[0016] Through the adsorption effect of the permanent magnet on the adsorption rod, the adsorption rod can be stably plugged into one side of multiple connecting rods, further ensuring the stability of the connection between the connecting plate, the connecting rod and the adsorption rod to the multiple modular polyurethane sieve plates. When disassembling, it is only necessary to pull out the permanent magnet, the adsorption rod and the connecting rod in turn to quickly release the connection and positioning between the two first support frames and one connecting frame, thereby reducing the labor intensity of the staff.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that when modular polyurethane sieve plates are installed, main beams or the like are usually required to splice multiple polyurethane sieve plates to adjust the screening area. However, since the polyurethane sieve plates need to screen materials, the contact area between the connecting structures such as main beams and each polyurethane sieve plate is small. When the materials to be screened are large, or the vibration frequency and amplitude are large, the connecting positions are more likely to generate gaps when vibrating, which may cause fine particles to enter the gaps and rub between the sieve plates and the connecting structures. Prolonged friction will shorten the service life of the sieve plates and the like. When screening materials through multiple modular polyurethane sieve plates, the materials fall onto the surface of the first support frame and the screening operation of the materials is carried out through the polyurethane sieve plate body. The connecting frame increases the connecting area between two first support frames, avoids slight bending of the first support frames under high-frequency vibration and other conditions, reduces the probability of fine particles entering the gaps between the two first support frames, and prolongs the service life of the modular polyurethane sieve plates.

[0019] 2. The utility model solves the problem that when modular polyurethane sieve plates are connected, rivets, bolts or the like are often required for stable connection. However, when a large number of modular sieve plates are connected, the connection and disconnection operations of rivets, bolts and the like are time-consuming and laborious. When assembling modular polyurethane sieve plates, according to needs, the connecting frame is inserted between two first support frames and a second support frame, then the connecting insertion rod penetrates through the first support frame, the connecting frame and the second support frame, and the adsorption insertion rod penetrates through one side of multiple connecting insertion rods. Finally, the permanent magnet is inserted into one end of the adsorption insertion rod to complete the connection of two modular polyurethane sieve plates. The operation is simple and convenient, and can simultaneously perform multi-point positioning connection on the modular sieve plates, improving the installation efficiency. When disassembling, only by sequentially pulling out the permanent magnet, the adsorption insertion rod and the connecting insertion rod, the connection positioning between two first support frames and a connecting frame can be quickly released, reducing the labor intensity of the staff.
