Figure 10 is a schematic view of a preferred i-shaped support post of the present invention. As shown in FIG. 10, the connecting column 113 includes a stiffener 1131 and a fastener 1132. The first end of the fixing member 1132 is fixedly disposed on the first support 111 and is not detachable, and the second end thereof is detachably disposed on the first support 111 through a screw hole 1133 and a screw adapted thereto. The reinforcement 1131 may be a right-angled triangular rib, the long right-angled side of which is fixedly disposed below the fixing member 1132, and the short right-angled side of which is welded to the second pillar 112 and extends from the second pillar 112 to the first pillar 111 without contacting with the first pillar 111. Of course, in other preferred embodiments, other shapes and arrangements of the connecting post 113 may be used, as long as it is ensured that the first post 111 can be detached from the connecting post 113.
As shown in fig. 8 to 10, the first side barrier 140 and the second side barrier 150 may have the same structure and be symmetrically disposed on both sides of the belt 500. As shown in fig. 8, the first side barrier 140 includes a rubber rib 141 contacting an upper portion of the belt 500, a rib pressing plate 142 disposed on an upper portion of the rubber rib 141, and a rib fixing member 143 fixing the rib pressing plate 142 on an upper portion of the i-shaped supporting pillar 110. The baffle fixing member 143 may be provided with a plurality of screw holes so as to be detachably fixed to the corresponding i-shaped support post 110 together with the corresponding screws. The belt 500 and the rubber barrier 141 may be made of a flame retardant antistatic material to prevent static electricity or burning due to friction.
As shown in fig. 8, the motor 600 is mounted on the driving roller 200 at a first side of the belt 500 by a detachable motor mount 610. Thus, when the belt 500 needs to be replaced, the motor 600 may be detached from the driving roller 200, the baffle fixing member 143 may be detached from the corresponding i-shaped supporting pillar 110, the flange pressing plate 142 and the rubber flange 141 may be removed, and the first supporting pillar 111 may be detached from the connecting pillar 113. Therefore, one side of the belt is completely opened, and the worker can take the belt down from the side surface of the belt conveyor and replace the belt with a new belt. Therefore, the whole replacing process is not only quick, but also labor-saving and convenient.
As further shown in fig. 8 to 10, the belt conveyor for a mineral processing plant further includes an anti-deviation switch 700 disposed between the front support plate 120 and the rear support plate 130, and the anti-deviation switch 700 includes a mounting base 710 and a switch vertical roller 720 contacting with both sides of the upper portion of the belt 500 for deviation indication. When the belt 500 deviates, the belt will make the switch vertical roller 720 deflect, and when the switch vertical roller 720 deflects for a certain angle, for example, 15 degrees, a deviation prompt will be sent. Any known anti-bias switch in the art may also be used herein.
As further shown in fig. 8 to 9, the belt conveyor for the mineral processing equipment further includes an automatic hydraulic deviation rectifying device 800 disposed at a lower portion of the mounting bracket 100. The present invention may employ any automatic hydraulic deviation correction device known in the art.
As further shown in fig. 8-9, the belt conveyor for a mineral processing apparatus further includes a carrier roller 1000 disposed at the bottom of the mounting bracket 100, and the carrier roller 1000 is located at one side of the aligning carrier roller 840 of the automatic hydraulic deviation rectifying device 800, which is close to the driven roller 300. In the preferred embodiment, the front supporting plate 120 and the rear supporting plate 130 can be supported by the belt 500 by using a stainless steel plate pair, and the idler 1000 only needs to be used as an auxiliary support, unlike the prior art, which is completely supported by the idler 1000, so that the risk of damage to the idler 1000 is reduced, and the service life of the equipment is prolonged.
As further shown in fig. 8-9, an X-ray sensor box 900 is disposed at the bottom of the mounting bracket 100 and between two i-shaped supporting columns 110 disposed near the active roller 200, and radiation-proof barriers 910 are disposed between the upper portions of at least two i-shaped supporting columns 110 above the X-ray sensor box 900 and the first side barrier 140 and the second side barrier 150, respectively, so as to effectively prevent physical damage to workers caused by X-ray radiation.
