TECHNICAL FIELD

[0001] The present application relates to the technical field of metal smelting equipment, in particular to a compression device for a matte vibrating screen sieve plate. BACKGROUND

[0002] The vibrating screen is a kind of screening device that drives the sieve box to vibrate through the vibration motor or the eccentric vibrator to achieve the screening of materials. In the production and processing of matte, the vibrating screen is needed to screen the matte. The existing vibrating screen generally uses a tensioning device to tension the screen mesh, and then uses a compression device to place the screen mesh on the lower supporting plate, and then uses bolts and screen mesh pressure strips to fix the screen mesh and the lower supporting plate.

[0003] The existing equipment has the following shortcomings: since the screen mesh is generally made of flexible steel wire mesh, the screen mesh is in an irregular arc state. When the screen mesh is placed on the supporting plate and fixed, the installer needs to align the side edges of the screen mesh with the mounting plate according to experience. This is greatly affected by the subjective factors of the installer and cannot be intuitively quantified. When the screen mesh is tensioned by the tensioning device, if the pressure applied on both sides is uneven, the screen mesh will be inclined. When the screen mesh is fixed by the compression device, the screen mesh will be inclined, which will cause the screen mesh to loosen or shift during vibration, affecting the screening effect.

[0004] Therefore, the present application proposes a compression device for a matte vibrating screen sieve plate to solve the above problems. SUMMARY

[0005] The present application aims to provide a compression device for a matte vibrating screen sieve plate to solve the problem that the screen mesh is installed with a certain inclination and is not accurately installed at the set position on the screen mesh frame, causing the screen mesh to loosen or shift during vibration and affecting the screening effect.

Then the screen mesh 2 is fixed on the vibrating screen 1. Through the arrangement of the device, the screen mesh 2 can be installed flat and accurately at the set position on the vibrating screen 1. Through the joint action of the pressing unit 3 and the fixed unit 4, the screen mesh 2 can be installed more stably on the vibrating screen 1, improving the screening efficiency and service life of the screen mesh 2. The worker only needs to align the side edges of the screen mesh 2 with the pressing unit 3, and then move the fixed unit 4 by the same distance, so that the screen mesh 2 can be tensioned evenly without testing the work experience of the worker.

[0039] In an embodiment, the pressing unit 3 comprises a pressing plate 31 arranged in a 7-shaped manner, positioning rods 32 arranged on the horizontal plate of the pressing plate 31 and penetrating the screen 2, and limiting blocks 33 arranged at positions corresponding to the positioning rods 32 on the side wall of the vibrating screen 1;

[0040] The positioning rods 32 are provided with installation grooves 321 at positions corresponding to the limiting blocks 33.

[0041] The vertical plate of the pressing plate 31 is clamped on the fixing unit 4.

[0042] In this way, when the screen 2 is installed, the vertical plate of the pressing plate 31 is aligned with the side edge of the screen 2, then the positioning rods 32 are vertically inserted into the mesh of the screen 2, then the pressing plate 31 is pulled outward, the vertical plate of the pressing plate 31 is inserted into the fixing unit 4, then the screen 2 is fastened by the fixing unit 4, and the displacement of the fixing unit 4 is the same, so that the screen 2 is subjected to the same tension on both sides, so that the screen 2 is in tension and is aligned with the installation position set on the vibrating screen 1, in the process of moving the pressing plate 31, the positioning rods 32 move towards the limiting blocks 33, the limiting blocks 33 are clamped in the installation grooves 321 on the positioning rods 32, the screen 2 is fixed at the position set on the vibrating screen 1, so that the screen 2 can be fixed in a flat and tight state in the vibrating screen 1, and the screening efficiency of the matte is improved.

[0043] In an embodiment, the fixing unit 4 comprises a screw rod 41 screwed on the side wall of the vibrating screen 1, a clamping block 42 arranged on the screw rod 41 on the inner side of the vibrating screen 1, and a limiting device 44 arranged on the side wall of the vibrating screen 1 for fixing the pressing plate 31.
