Description
Technical Field
[0001] The utility model relates to a cross-screen coarse material guiding device, belonging to the technical field of cross-screens. Background Art
[0002] The cross screen is a device for screening coarse and fine materials. In alumina production, the cross screen is used to screen the ore. The coarse and fine materials after screening are transferred through different discharge ports. After transfer, the coarse material enters the crushing device for further crushing.
[0003] During production, there will be some batches of fine ore materials, and the coarse material entering the crushing device is less, which cannot meet the feeding requirements of the crusher. If the coarse material crushing is continued, it will undoubtedly cause the crusher to idle, which seriously wastes energy.
[0004] That is, a cross-screen coarse material guiding device is now needed, which can prevent the coarse material from entering the crusher when there is little coarse material, thereby stopping the operation of the crusher and achieving energy saving. Utility Model Content
[0005] In view of this, the purpose of the utility model is to provide a cross-screen coarse material guiding device, which can prevent coarse material from entering the crusher when there is little coarse material, thereby stopping the operation of the crusher and achieving energy saving; it can overcome the shortcomings of the prior art.
[0006] The purpose of this utility model is achieved through the following technical solutions:
[0007] The utility model discloses a cross-screen coarse material guiding device, which comprises a cross-screen body, on which a coarse material guiding groove and a fine material guiding groove are arranged, the coarse material guiding groove is connected to a crusher, a coarse material second outlet is arranged on one side of a feeding port of the coarse material guiding groove, a coarse material second guide groove connected to a coarse material temporary storage place is arranged at the coarse material second outlet, a guide plate is hinged at the coarse material second outlet, the guide plate guides the coarse material into the coarse material guiding groove or the coarse material second guide groove after rotation, and a rotation control device of the guide plate is arranged on the cross-screen body.
[0008] The above-mentioned rotation control device includes a traction rope connected to the free end of the guide plate, and a rope collecting device for the traction rope is provided on the cross screen.
[0009] The rope collecting device is an electric hoist or a rope collecting motor, and a wire collecting wheel is connected to the rotating shaft of the rope collecting motor.
[0010] As mentioned above, a through hole is provided on the side wall of the cross screen body, and the traction rope passes through the through hole and is connected to the rope collecting device.
[0011] As mentioned above, a connecting arm is provided on the side wall of the cross screen body at the upper end of the second coarse material outlet, and a screw hole and a screw are provided on the connecting arm. The screw is screwed downward to limit the free end of the guide plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model provides a second coarse material outlet at one side of the discharge port of the coarse material guide groove, a second coarse material guide groove connected to the coarse material temporary storage is provided at the second coarse material outlet, a guide plate is hinged at the second coarse material outlet, and the guide plate guides the coarse material into the coarse material guide groove or the second coarse material guide groove after rotation, and a rotation control device of the guide plate is provided on the cross screen body. In this way, by providing the second coarse material outlet and the second coarse material guide groove, when encountering finer ore materials and less coarse materials, the guide plate can be rotated by the rotation control device to seal the coarse material pipeline originally leading to the crusher, so that a small amount of coarse materials can be introduced into the coarse material temporary storage through the second coarse material guide groove. When enough coarse materials are accumulated, they are crushed uniformly. During this process, the operation of the crusher can be stopped, which is beneficial to reducing energy consumption. At the same time, the guide plate can be easily rotated by the rotation control device to determine whether the coarse materials are transported by the coarse material guide groove or the second coarse material guide groove, saving manpower and material resources.
[0014] 2. The rotation control device includes a traction rope connected to the free end of the guide plate, and a traction rope collecting device is provided on the cross screen. In this way, when it is necessary to close the coarse material passage to the crusher, the guide plate is lowered through the rope collecting device until the free end of the guide plate rests on the other side wall of the cross screen body, thereby sealing the discharge port of the original coarse material guide groove, and then the material enters the second coarse material guide groove from the guide plate to the second coarse material outlet, so as to transfer a small amount of coarse material.
[0015] 3. A connecting arm is provided on the side wall of the cross screen body at the upper end of the second coarse material outlet, and a screw hole and a screw are provided on the connecting arm. The screw is rotated downward to limit the free end of the guide plate. In this way, when it is not necessary to block the coarse material leading to the crusher, the guide plate puller is rotated to vertically block the second coarse material outlet through the rotating control device, and the free end of the guide plate is limited by rotating the screw downward.

DETAILED DESCRIPTION
[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.
[0026] like Figure 1-Figure 6 As shown, the utility model discloses a cross-screen coarse material guiding device, which mainly consists of: a cross-screen body 1, a coarse material guiding groove 2, a fine material guiding groove 3, a crusher 4, a coarse material second guiding groove 6 and a rotation control device.
[0027] Specifically, a coarse material guide groove 2 and a fine material guide groove 3 are provided on the cross screen body 1, the coarse material guide groove 2 is connected to the crusher 4, a coarse material second outlet 5 is provided on one side of the discharge port of the coarse material guide groove 2, a coarse material second guide groove 6 connected to the coarse material temporary storage is provided at the coarse material second outlet 5, a guide plate 7 is hinged at the coarse material second outlet 5, the guide plate 7 is rotated to guide the coarse material into the coarse material guide groove 2 or the coarse material second guide groove 6, and a rotation control device of the guide plate 7 is provided on the cross screen body 1; such a structure can block the original coarse material through the coarse material second guide groove 6 when encountering a mineral material with less coarse material. The present invention leads to the discharge port of the crusher 4, and then guides the relatively small amount of coarse material to the temporary storage place through the second coarse material guide groove 6 for storage. When enough coarse material is accumulated, it is crushed. In this way, the operation of the crusher 4 can be stopped when there is less coarse material, thereby achieving the purpose of energy saving. The guide plate 7 itself is a steel plate, which is relatively thick. If the original coarse material outlet is blocked by manually rotating the guide plate 7, it is quite laborious and requires the assistance of multiple people. Therefore, through the rotation control device of the guide plate 7, the free end of the guide plate 7 can be automatically lowered or lifted to achieve the flipping of the guide plate 7, thereby saving manpower and material resources.
[0028] Furthermore, the rotation control device includes a traction rope 8 connected to the free end of the guide plate 7, and a rope collecting device for the traction rope 8 is provided on the cross screen body 1. Specifically, the rope collecting device is an electric hoist or a rope collecting motor 9, and a wire collecting wheel is connected to the rotating shaft of the rope collecting motor 9. A through hole is provided on the side wall of the cross screen body 1, and the traction rope 8 passes through the through hole and is connected to the rope collecting device. In this way, when the free end of the guide plate 7 is controlled to rotate, the traction rope 8 is unfolded by the rotation control device, and the free end of the guide plate 7 can be slowly lowered. During the lowering process, the traction rope 8 can keep the guide plate 7 taut at all times. In this way, when the free end of the guide plate 7 contacts the side wall of the cross screen body 1, the impact force is small, which is also beneficial to protecting the cross screen body 1. When the free end of the guide plate 7 leans against the inner wall of the cross screen body 1, the guide plate 7 is inclined toward the second coarse material outlet 5, which is beneficial to introducing the coarse material toward the second coarse material outlet 5; at the same time, when it is necessary to lift the guide plate 7, it is only necessary to collect the rope through the rope collecting device to achieve the lifting of the free end of the guide plate 7.
[0029] A connecting arm 10 is provided on the side wall of the cross screen body 1 at the upper end of the second coarse material outlet 5. The connecting arm 10 is welded and fixed to the cross screen body 1. A screw hole and a screw rod 11 are provided on the connecting arm 10. The screw rod 11 is rotated downward to limit the free end of the guide plate 7. With this structure, when the guide plate 7 is not needed to block the original discharge port, the free end of the guide plate 7 is close to the second coarse material outlet. At this time, the screw rod 11 is rotated downward to limit the upper end of the guide plate 7, thereby avoiding the situation where the guide plate 7 flips over to block the normal discharge during use.
[0030] The above is only a preferred embodiment of the utility model, and does not limit the confidentiality of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
