Technical Field

[0001] The utility model relates to the technical field of pulp separators, in particular to a device for improving the maintenance efficiency of pulp separators of flotation columns. Background Art

[0002] The flotation column is an important equipment for sorting minerals. It is equipped with a slurry separator inside. The function of the slurry separator is to evenly distribute the slurry into the flotation column to ensure the flotation effect. However, during long-term use, the slurry separator may have problems such as wear and blockage, and needs to be regularly inspected. The traditional maintenance method usually requires shutting down and opening the end cover of the flotation column before the slurry separator can be inspected. This method is not only cumbersome to operate, but also inefficient.

[0003] In order to solve the above problems, some improved slurry separator maintenance devices have been proposed. However, the existing maintenance structures often have defects such as poor sealing performance and inconvenient operation, which are difficult to meet the needs of fast and efficient maintenance. Therefore, how to design a slurry separator maintenance device that can both improve maintenance efficiency and ensure good sealing performance has become a problem that needs to be solved urgently in the current slurry separator technology field.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a device for improving the maintenance efficiency of the flotation column slurry separator, such as Figure 1-Figure 3 As shown, it includes a square inspection hole 1, which is arranged on the side wall of the pulp separation cylinder 6. The outer side of the inspection hole 1 is sealed by a blind plate 5. The shape and size of the blind plate 5 are adapted to the shape and size of the inspection hole 1. Supports 2 are arranged on both sides of the inspection hole 1, and force plates 3 are installed between the outer ends of the supports 2. A push rod 4 is installed in the middle of the force plate 3, and one end of the push rod 4 presses the blind plate 5 onto the pulp separation cylinder 6.

[0022] In this embodiment, one end of the support 2 is welded to the outer wall of the slurry separation cylinder 6 to facilitate the installation and fixation of the support 2.

[0023] Specifically, a through hole is provided at the outer end of the support 2 , and both ends of the force-bearing plate 3 pass through the through hole, and a limiting plate 32 is installed at the end to limit the position of the force-bearing plate 3 .

[0024] Furthermore, a threaded hole 31 is provided in the middle of the force-bearing plate 3 , and an outer wall of the push rod 4 is provided with an external thread 41 . The push rod 4 is threadedly connected to the threaded hole 31 , so that the push rod 4 can rotate to tighten the blind plate 5 .

[0025] Furthermore, a handle 42 is vertically mounted on the outer end of the push rod 4, and the push rod 4 is driven to rotate by the handle 42, thereby achieving a tightening operation.

[0026] Furthermore, a circle of annular grooves 11 are provided at the opening of the inspection hole 1, and a sealing strip is also provided in the annular groove 11. A tenon is installed on the inner side of the blind plate 5, and the inner side of the blind plate 5 is snap-fitted with the annular groove 11 through the tenon to ensure the sealing between the blind plate 5 and the inspection hole 1.

[0027] Furthermore, the width of the through hole at the outer end of the support 2 is greater than the width of the limiting plate 32 , so that the force-bearing plate 3 can be easily pulled out.

[0028] Furthermore, a pressing plate 43 is installed at one end of the force-bearing plate 3 close to the blind plate 5 to ensure that the blind plate 5 is pressed and fixed.

[0029] When the utility model is used, the device for improving the maintenance efficiency of the flotation column slurry separator mainly relies on the coordinated action of the inspection hole 1, the blind plate 5, the support 2, the force plate 3 and the push rod 4. The inspection hole 1 is used as the inspection entrance, and its square design is convenient for operation and sealing. The blind plate 5 is used to form a seal on the outside of the inspection hole 1, and its size is closely matched with the inspection hole 1 to ensure the sealing effect. The support 2 provides a stable structural support to ensure that the force plate 3 and the push rod 4 can accurately apply force. During the maintenance process, the push rod 4 is first driven to rotate by rotating the handle 42. Due to the threaded connection between the push rod 4 and the force plate 3, the rotation of the push rod 4 will cause it to move along the axial direction of the force plate 3. When maintenance is required, the handle 42 is rotated in the opposite direction, the push rod 4 moves backward, and the blind plate 5 is loosened. At this time, the blind plate 5 can be removed from the inspection hole 1 to expose the inspection hole 1, and the maintenance personnel can inspect the slurry separator 6 through the inspection hole 1. After the inspection is completed, the blind plate 5 is put back to the inspection hole 1, the handle 42 is rotated forward, the push rod 4 moves forward, and the blind plate 5 is pressed against the pulp distribution cylinder 6 by the pressure plate 43. At the same time, the tenon on the inner side of the blind plate 5 is engaged with the annular groove 11 at the opening of the inspection hole 1 to achieve sealing between the blind plate 5 and the inspection hole 1.

[0030] In addition, the width of the through hole at the outer end of the support 2 is greater than the width of the limiting plate 32. This design allows the force-bearing plate 3 and the top rod 4 to be easily pulled out when necessary, further enhancing the flexibility and practicality of the structure.
