Problems solved by technology

[0003] In the actual use process, due to poor rigidity, insufficient tension, and excessive longitudinal and transverse lengths, the screen and the screen frame often vibrate out of sync, resulting in mutual friction and damage to the middle beam and cross beam of the screen and the screen frame. even damage the entire screen box
If the screen is damaged, it needs to be replaced as a whole. The replacement cost is relatively high, the production efficiency is poor, and the cost is high.

specific Embodiment 1

[0033] The woven screen combined vibrating screen in this example includes a vibrating device, a screen box, and a woven screen; the screen box includes a beam, a middle beam, an end plate, and a side plate; There are two beams in the horizontal direction; the section of the woven screen is Z-shaped, and each vibrating screen is composed of two woven screens. The two woven screens are respectively installed on both sides of the middle beam, and the Z-shaped ends of the woven screen are fixed on On the side panels and the center beam, tie the edges upward on the side panels and downward on the center beam.

[0034] The structure of the upward binding on the side panels is the same as image 3 and its description.

[0035] The structure of the downward binding on the middle beam is the same as Figure 4 and its description.

[0036] The two sides of the U-shaped groove used are inclined 60 degrees inward, the side length is 40mm, and the width of the upper opening is about 60...

specific Embodiment 2

[0038] The woven screen combined vibrating screen is composed of six woven screens in this example, and the other structures are the same as those in Embodiment 1.

[0039] Installation steps: After assembling and preparing the screen box, first install the woven screen from the discharge port, spread the screen tightly on the edge of the discharge port of the vibrating screen, tie the edge up close to the side plate, and hook it downward U-shaped groove, the second screen only needs to overlap 20-30mm at the joint of the screen, and the other assembly forms are the same as the first one, and there are three screens on each side of the center beam. Install the tensioning plate and pressure plate separately, pre-tension the tensioning plate appropriately first, then tighten the pressure plate bolts, and finally tighten the tensioning plate bolts.

[0040] During concrete production combination, also can have four, eight, ten structures such as. Its installation method is the s...

specific Embodiment 3

[0041] This example is the same as Embodiment 1 or Embodiment 2, except that there are two rubber strips in the longitudinal direction of the screen box; they are respectively located on both sides of the center beam, in the middle of the center beam and the side plates, and under the woven screen. The rubber strip 17 is fixedly installed on the steel strip, and the steel strip is welded and fixed on the end plate 18, the beam 16 and the discharge port. The rubber strip 17 further increases the horizontal support of the screen, reduces the deformation of the screen, and makes the vibration of the screen and the screen frame more stable. Synchronize.

Abstract

The invention discloses a combined woven screen vibrating screen, which comprises a vibrating device, a screen box and a woven screen, wherein the screen box comprises cross beams, a middle beam, an end plate and a side plate; the end plate and the side plate form a screen frame; the longitudinal middle of the screen frame is provided with the middle beam, and the transverse direction of the screen frame is provided with at least two cross beams; the section of the woven screen is Z-shaped; each vibrating screen at least consists of two woven screens; two Z-shaped ends of the woven screen arefixed on the side plate and the middle beam; and the side plate is upwards bound, and the middle beam is downwards bound. By reducing the size of each screen, changing the structure of the screen andadopting a new fixing method, the steel wire woven screen type vibrating screen is more convenient to fix and easier to perform local exchange, the whole screen and the middle beam do not produce friction any more, the service life of the screen is prolonged, the cost is saved, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mining machinery manufacturing, in particular to the field of woven screen vibrating screen manufacturing, in particular to the manufacture of woven screen combined vibrating screens. Background technique [0002] The vibrating screen equipped with a woven screen is a common equipment for mine beneficiation. The woven screen is generally made as a tension type, and the two sides are tied to the same direction at 45 degrees. The reinforced half-round head square neck bolts and tension plates are used to tension both sides. Fixed, with a certain height raised in the middle, so that it can work together with the screen frame. [0003] In the actual use process, due to poor rigidity, insufficient tension, and excessive longitudinal and transverse lengths, the screen and the screen frame often vibrate out of sync, resulting in mutual friction and damage to the middle beam and cross beam of the screen and the screen fram...
