Technical Field
[0001] The utility model relates to the technical field of screen meshes, in particular to a spliced tensioned screen mesh. Background Art
[0002] Tension screen, especially polyurethane tension screen, is a new type of screen, commonly used in vibrating screens, fluidized beds and various chemical equipment. With its high elasticity, wear resistance and tensile resistance, it is suitable for screening various materials such as coal, iron ore, copper ore, sand and gravel aggregates.
[0003] The existing commonly used screens are basically a whole piece of screen. In fact, they are formed in one piece. During the long-term operation of the screen, the screen is easily worn or the screen holes are damaged, resulting in damage to a certain area of the screen and affecting the screening operation. At this time, the staff will replace the entire screen, and the replaced screen cannot be used anymore, which will cause a waste of resources and increase production costs. For this reason, the utility model provides a spliced tensioning screen. Utility Model Content

[0013] The present invention designs a spliced tensioning screen, which replaces the traditional integral screen by combining multiple screen plates. When the screen is damaged, the corresponding screen plate can be directly replaced without replacing the entire screen. This not only greatly saves costs and reduces losses, but also is convenient to replace and install, effectively reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0019] See also Figure 1-3 The utility model provides a technical solution for a spliced tensioning screen: a spliced tensioning screen, which consists of two first screen plates 1 and a second screen plate 2. An upper connecting plate 5 is provided at one end of the first screen plate 1, and a hanging plate 3 is provided at the other end of the first screen plate 1. The hanging plate 3 and the upper connecting plate 5 are both integrally formed with the first screen plate 1, and the two lower connecting plates 21 are both integrally formed with the second screen plate 2. Both the first screen plate 1 and the second screen plate 2 are polyurethane screens, which have the characteristics of corrosion resistance and high temperature resistance, and are also relatively strong in elasticity and toughness.
[0020] The two ends of the second sieve plate 2 are symmetrically provided with lower connecting plates 21, and the surfaces of the two lower connecting plates 21 and the surface of the upper connecting plate 5 are provided with positioning holes 6. The positions of the positioning holes 6 on the surfaces of the lower connecting plates 21 and the upper connecting plates 5 correspond to each other. The first sieve plate 1 and the second sieve plate 2 are connected through the lower connecting plate 21 and the upper connecting plate 5, and the upper connecting plate 5 and the lower connecting plate 21 are fixed by positioning screws 7 and positioning holes 6. The screen is formed by splicing the two first sieve plates 1 with the two side edges of the second sieve plate 2 respectively. When splicing, the first sieve plate 1 is clamped on the lower connecting plate 21 at one end of the second sieve plate 2 through the upper connecting plate 5 at one end thereof, so that the positioning holes 6 on the upper connecting plate 5 and the lower connecting plate 21 are aligned, and the positioning screw 7 is inserted into the positioning hole 6. After tightening the nut, the splicing of the upper connecting plate 5 and the lower connecting plate 21 can be achieved, so that the two first sieve plates 1 and the second sieve plates 2 can be spliced to form a screen.
[0021] The sizes of the upper connecting plate 5 and the lower connecting plate 21 are adapted to each other, and the sum of the thicknesses of the upper connecting plate 5 and the lower connecting plate 21 is the same as the thicknesses of the first sieve plate 1 and the second sieve plate 2. Therefore, when the upper connecting plate 5 and the lower connecting plate 21 are spliced together, they can be made flush with the surfaces of the first sieve plate 1 and the second sieve plate 2, thereby ensuring the flatness of the screen surface.
[0022] The first sieve plate 1 and the second sieve plate 2 are provided with reinforcing ribs 4 in the longitudinal and transverse directions, and the surfaces of the first sieve plate 1 and the second sieve plate 2 are provided with a plurality of sieve holes 8, the sieve holes 8 are rectangular, circular or trapezoidal structures, and the hole shape of the sieve holes 8 can be selected according to actual needs, which is more conducive to the screening operation of the material.
[0023] The working principle of the utility model is as follows: when assembling the screen of this design, the two first screen plates 1 are placed on both sides of the second screen plate 2, and then the upper connecting plate 5 of the first screen plate 1 is clamped on the lower connecting plate 21 at one end of the second screen plate 2, so that the positioning holes 6 on the upper connecting plate 5 and the lower connecting plate 21 are aligned;
[0024] Then insert the positioning screw 7 into the positioning hole 6 and tighten the nut to achieve the splicing of the upper connecting plate 5 and the lower connecting plate 21, so that the first screen plate 1 and the second screen plate 2 can be spliced to form a screen;
[0025] When in use, the screen can be installed on the working equipment using the hanging plate 3 on the other side of the two first screen plates 1, so as to facilitate the screening operation of the material. Moreover, during the operation, when a certain screen plate is damaged, the fixing of the upper connecting plate 5 and the lower connecting plate 21 by the positioning screw 7 can be directly released, so that the damaged screen plate can be replaced. The screen is composed of multiple screen plates, which are combined and spliced to replace the traditional integral screen. When the screen is damaged, the corresponding screen plate can be directly replaced without replacing the entire piece. This not only greatly saves costs and reduces losses, but also is convenient to replace and install, effectively reducing production costs.
[0026] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
