Description

Technical Field

[0001] This utility model belongs to the technical field of copper concentrate dewatering equipment, specifically relating to a copper concentrate dewatering device. Background Technology

[0002] In the beneficiation process of copper concentrate, dewatering is one of the key steps, directly affecting the transportation cost of the concentrate and the efficiency of subsequent smelting. Currently, ceramic vacuum filters are widely used in the initial dewatering of copper concentrate due to their high efficiency and energy saving. This equipment uses the principle of vacuum adsorption to allow water in the slurry to pass through ceramic filter plates and be discharged, while solid particles form a filter cake, achieving solid-liquid separation.

[0003] However, existing ceramic vacuum filters have significant drawbacks in the feeding stage: their top feed inlets are typically fixed, lacking removable filter screens and corresponding transmission structures. Copper concentrate often contains coarse particles, fibrous impurities, or crushed media (such as rubber and plastics). These impurities easily accumulate at the feed inlet and may even enter the filtration zone, leading to the following problems:

[0004] Filter clogging: Debris adheres to the surface of the ceramic filter plate, reducing its air permeability, affecting vacuum adsorption efficiency, and increasing energy consumption;

[0005] Uneven filter cake: Impurities interfere with the distribution of slurry, resulting in uneven filter cake thickness and reduced dewatering effect.

[0006] Therefore, there is an urgent need for a copper concentrate dewatering device that is simple in structure and easy to maintain.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] The purpose of this invention is to provide a copper concentrate dehydration device to solve the problems of the prior art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A copper concentrate dewatering device includes a ceramic vacuum filter. A filter screen is movably installed at the top feed inlet of the ceramic vacuum filter. A detachable transmission assembly is connected between the outer side of the filter screen and the top feed inlet of the ceramic vacuum filter. The detachable transmission assembly can be used to drive the filter screen to shake and swing, and can also be used to assemble and disassemble the filter screen.

[0011] Preferably, the detachable transmission assembly includes a gear ring rotatably connected to the periphery of the feed inlet, and a plurality of gears arranged in a circular array meshing around the periphery of the gear ring. A rotating shaft is fixedly connected to the mounting shaft hole of each gear, and the bottom end of each rotating shaft is rotatably connected to the support base. The support base is fixedly connected to the outside of the feed inlet, and the bottom end of one of the rotating shafts extends to the bottom of the support base and is fixedly connected to the output shaft of the drive motor.

[0012] Preferably, a turntable is fixedly connected to the top extension of the rotating shaft, a push-pull rod is rotatably connected to the surface edge of the turntable, a rotating column is rotatably connected to the top of the other end of the push-pull rod, and a support block is fixedly connected to the outer side of the rotating column.

[0013] Preferably, a gap of 3mm is reserved between the bottom end of the support block and the top end of the push-pull rod.

[0014] Preferably, each of the support blocks has a sleeve block movably overlapping its top, the sleeve block being sleeved on the outside of the rotating column, and one end of each sleeve block being fixed to the outside of the filter screen.

[0015] Preferably, the top of each of the sleeve blocks is also provided with a hand-tightening nut that is threaded to the outside of the rotating column.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The copper concentrate dewatering device of this utility model starts the drive motor, which in turn drives the corresponding gear transmission gear ring. The gear ring meshes with multiple gears, which makes the rotation direction of multiple gears consistent. The rotation direction of the turntable connected to the rotating shaft is also consistent. With the setting of multiple push-pull rods, the filter screen can swing and shake at the top of the feed inlet of the ceramic vacuum filter, thereby filtering and screening impurities in the copper concentrate material, avoiding impurities from interfering with the distribution of the slurry, causing uneven filter cake thickness, and affecting the dewatering effect.

[0018] (2) Secondly, when it is necessary to replace the filter screen, multiple hand-tightened nuts can be loosened, and multiple sleeves on the outside of the filter screen can be lifted and removed from the outside of the rotating column, so as to facilitate the replacement of the filter screen and prevent clogging from affecting the subsequent vacuum adsorption efficiency.

[0027] Filter clogging: Debris adheres to the surface of the ceramic filter plate, reducing its air permeability, affecting vacuum adsorption efficiency, and increasing energy consumption;

[0028] Uneven filter cake: Impurities interfere with the distribution of slurry, resulting in uneven filter cake thickness and reduced dewatering effect.

[0029] See attached document Figure 1-3A copper concentrate dewatering device includes a ceramic vacuum filter 1.

[0030] Furthermore, such as Figure 1-3 As shown, in order to enable the filter screen 2 to swing and oscillate, and to facilitate the replacement of the filter screen 2, a detachable transmission assembly 3 is provided, including a gear ring 31 rotatably connected to the periphery of the feed inlet. Multiple gears 32 arranged in a circular array are meshed around the periphery of the gear ring 31. A rotating shaft 33 is fixedly connected to the mounting shaft hole of each gear 32. The bottom end of each rotating shaft 33 is rotatably connected to a support base 34, which is fixedly connected to the outside of the feed inlet. The bottom end of one rotating shaft 33 extends to the bottom of the support base 34 and is fixedly connected to the output shaft of the drive motor 310. The top end of the rotating shaft 33 extends... Each extension is fixedly connected to a turntable 35. Each turntable 35 is rotatably connected to a push-pull rod 351 at the edge of its surface. Each push-pull rod 351 is rotatably connected to a rotating column 36 at the top of its other end. Each rotating column 36 is fixedly connected to a support block 37 on its outer side.
