Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing equipment, in particular to a cylindrical ore dressing screening machine. Background Art

[0002] Ore washing and mineral separation is the most important link in the whole mineral production process. It is the process of removing clay materials from the ore. The ore materials need to be screened by a screening machine. Most of the existing cylindrical screening machines can only perform one screening, but one screening cannot achieve the classification effect. It is often necessary to configure multiple devices for multiple screenings, resulting in increased sorting investment. In this regard, the technicians in this field proposed a cylindrical mineral separation screening machine with good screening efficiency disclosed in CN215902191U, which sets two screening cylinders into an integrated machine. When in use, the first screening cylinder is driven to rotate by the driving device, and the second screening cylinder is driven to rotate by the transmission device. The minerals are first screened once in the second screening cylinder, and then screened twice by the first screening cylinder. In this way, the screening is completed, solving the problem of low efficiency of the existing cylindrical mineral separation screening machine, and the first screening cylinder and the second screening cylinder are rotated in opposite directions by the driving device and the transmission device. The reverse rotation can increase the screening effect, and the connecting rod is irregularly fixed on the shaft rod. This method can stir the minerals and improve the working efficiency of the equipment.

[0003] The traditional drum screening machine is composed of a rotating drum and a cylindrical filter. In view of the above problems, this application considers starting from the efficient and convenient disassembly and assembly of the cylindrical filter, and realizing sorting by quickly changing the mesh size of the cylindrical filter. However, the cylindrical filter of the traditional drum sorting machine is fixedly connected to the rotating drum at multiple points through screw and nut fixings, which makes the disassembly and assembly cumbersome and time-consuming, seriously affecting the sorting efficiency. Therefore, this application aims to provide a drum screening machine with efficient disassembly and assembly of the cylindrical filter. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical problems and technical solutions solved by the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 Figure 2 As shown, a cylindrical mineral processing screening machine includes a frame 1, a drum 2, a cylindrical filter 3 and a driving motor 4. The drum 2 is rotatably installed above the frame 1, and the cylindrical filter 3 is installed in the drum 2. The end of the drum is driven and connected to the driving motor 4. The output shaft of the driving motor 4 is connected to the shell of the drum 2, and the drum 2 is driven to rotate, thereby driving the cylindrical filter 3 to rotate together for sorting operations. The structure of this part is an existing conventional design.

[0023] The frame 1 is U-shaped, and two or more groups of rollers are symmetrically installed on both sides of the bottom plate for rotating the drum 2. Baffles are provided on both sides of the frame to ensure that the drum 2 can be firmly fixed on the frame 1 during rotation, thereby improving the stability of the frame.

[0024] like Figure 3As shown, the drum 2 and the cylindrical filter 3 are connected and installed through at least two symmetrically arranged installation components, the installation components include a spring rod 501 and a locking block 502, one end of the spring rod 501 is connected to the outer surface of one end of the cylindrical filter 3, and the other end is connected to the locking block 502, and the inner wall of the drum 2 is correspondingly provided with a pressing opening 503 for the locking block 502 to slide through and a locking groove 504 for the locking block 502 to lock. In order to facilitate the locking block 502 to slide into the locking groove 504, the cross section of the locking block 502 is set to a triangle, and the corresponding pressing opening 503 and the locking groove 504 are also set to a triangle.

[0025] When it is necessary to install the cylindrical filter 3, the two locking blocks 502 are aligned with the two pressing ports 503 respectively, and then the cylindrical filter 3 is pushed into the drum 2, and the locking blocks 502 are close to the pressing ports 503. When the inclined surface of the locking blocks 502 slides and contacts with the inclined surface of the pressing port 503, the spring rod 501 contracts under the action of the inclined surface pressing until the end of the cylindrical filter 3 abuts against the inner wall of the drum 2. At this time, the two locking blocks 501 correspond to the positions of the two locking grooves 504 respectively, and the pressing force of the inner wall of the drum 2 on the locking blocks 501 disappears. The locking blocks 502 are quickly reset under the elastic potential energy of the spring rods 501 and inserted into the locking grooves 504 corresponding to their positions, thereby completing the installation of the cylindrical filter 3. When it is necessary to disassemble the cylindrical filter 3, the two spring rods 501 are compressed, and the two locking blocks 502 are respectively moved out of the two locking grooves 504 to release the locking of the cylindrical filter 3, which is convenient and quick.

[0026] In order to facilitate the removal of the cylindrical filter screen 3, a pull plate 6 is sleeved on one end of the spring rod 501 close to the locking block 502, and the surface of the pull plate 6 is provided with anti-slip grooves, and the two spring rods 501 can be easily compressed by the two pull plates 6.

[0027] In order to prevent the cylindrical filter screen 3 from falling off due to the contraction of the spring rod 501 when the cylindrical filter screen 3 rotates at high speed with the drum 2, the installation assembly 5 is also equipped with a limiting assembly for limiting the contraction of the spring rod 501. The limiting assembly includes a rotating shaft 701, a limiting plate 702 and a torsion spring 704. The end surface of the cylindrical filter screen 3 corresponding to the spring rod 501 is provided with a mounting opening 703. The rotating shaft 701 is rotatably mounted on the mounting opening 703. One end of the limiting plate 702 is rotatably mounted on the rotating shaft 701, and the other end abuts against the surface of the pull plate 6. Two torsion springs 704 are sleeved on the rotating shaft 701, and the two ends of the two torsion springs 704 are respectively connected to the wall of the mounting opening 703 and the surface of the limiting plate 702.

[0028] When the cylindrical filter 3 is locked, the ends of the two limiting plates 702 will respectively contact the surfaces of the two pull plates 6 under the elastic potential energy of the torsion spring 704. At this time, the pull plates 6 are blocked by the limiting plates 702 and cannot control the contraction of the spring rod 501. Only by controlling the rotation of the limiting plates 702 until the limiting plates 702 rotate to the point where the ends no longer conflict with the surfaces of the pull plates 6, can the pull plates 6 be controlled to move, thereby controlling the contraction of the spring rod 501. When the limiting plates 702 are released, the limiting plates 702 will quickly rotate and reset under the elastic potential energy of the torsion spring 704, so that the ends of the limiting plates 702 will conflict with the surfaces of the pull plates 6 again. The limiting assembly can effectively limit the contraction of the spring rod 501. Even if the cylindrical filter 3 rotates at a high speed, the contraction of the spring rod 501 will not cause the locking block 502 to disengage from the locking groove 504, thereby ensuring the safety and stability of the equipment during operation.

[0029] like Figure 4 As shown, the device further includes at least two symmetrically arranged guide mechanisms, which include a guide opening 801 arranged on the inner wall of the drum 2 and a guide rod 802 correspondingly arranged on the cylindrical filter screen 3, and the two guide rods 802 are slidably inserted into the two guide openings 801. When installing the cylindrical filter screen 3, it is only necessary to align the two guide rods 802 into the two guide openings 801 respectively, so that the positions of the two locking blocks 502 and the two pressing openings 503 can be quickly aligned, thereby realizing rapid alignment and installation, which is convenient and quick.

[0030] like Figure 5 As shown, a connecting rod 9 is connected to the housing of the driving motor 4, and the other end of the connecting rod 9 is connected to the frame 1, so that the installation of the driving motor 4 can be more stable.

[0031] In the present invention, when the cylindrical filter screen 3 needs to be installed, first align the two guide rods 802 on the cylindrical filter screen 3 with the two guide openings 801 on the rotating drum 2, and push the cylindrical filter screen 3 inward. When the two locking blocks 501 are aligned with the two pressing openings 503, rotate the limiting plate 702 to release the blocking of the limiting plate 702 on the pulling plate 6. When the inclined surfaces of the two locking blocks 501 slide in contact with the inclined surfaces of the pressing openings 503, the spring rod 501 is pressed under the action of the inclined surfaces of the pressing openings 503. Contraction, until the two locking blocks 501 slide to the two corresponding locking grooves 504, the pressing force exerted on the locking blocks 501 by the inner wall of the rotating drum 2 disappears, and the locking blocks 501 are quickly reset and inserted into the locking 504 under the elastic potential energy of the spring rod 501. At the same time, the limiting plate 702 is released, and the limiting plate 702 is quickly rotated and reset under the elastic potential energy of the torsion spring 704, so that its end contacts the surface of the pulling plate 6, limiting the contraction of the spring rod 501, thus completing the installation of the cylindrical filter 3.

[0032] After the installation of the cylindrical filter 3 is completed, the mineral to be screened is put into the cylindrical filter 3, and then the cover of the drum 2 is closed, and the drive motor 4 can be started. The output shaft of the drive motor 4 rotates with the drum 2 and the cylindrical filter 3, and the material in the cylindrical filter 3 will roll. The minerals of qualified size will move out from the filter holes of the cylindrical filter 3 and fall into the drum 2, while the larger minerals cannot pass through the filter holes of the cylindrical filter 3 and remain in the cylindrical filter 3, completing the mineral sorting.

[0033] If multi-stage sorting is required, a cylindrical filter screen 3 with larger mesh size can be installed to first sort the coarse particles, and then replaced with a cylindrical filter screen 3 with smaller mesh size to sort the fine particles, and this can be repeated until qualified minerals are sorted out.

[0034] When it is necessary to disassemble the cylindrical filter 3, rotate the two limiting plates 702 to release the obstruction of the limiting plates 702 to the pulling plates 6, pull the two pulling plates 6, and the spring rod 501 contracts, so that the two locking blocks 502 are respectively moved out of the two locking grooves 504 to release the lock on the cylindrical filter 3, and then pull the cylindrical filter 3 outward to make the two guide rods 802 on the cylindrical filter 3 completely leave the two guide openings 801, and the disassembly of the cylindrical filter 3 can be completed.

[0035] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above, and any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
