Description

Technical Field

[0001] This utility model relates to the technical field of vacuum filter press unit accessories, specifically a modular frame for vacuum filter press units. Background Technology

[0002] A vacuum filter press unit is a solid-liquid separation device used in mineral processing to dehydrate water-containing lithium concentrate, obtaining a filter cake with lower moisture content for easier subsequent processing or transportation. The vacuum filter press unit requires a frame support system to support the filter components, control components, and vacuum system components. Currently, some parts of the frame are non-disassembleable, resulting in low installation tolerance.

[0003] For example, the filter press frame disclosed in the existing patent publication number CN206896923U includes a support base assembly, a crossbeam assembly, and a connecting assembly. The support base assembly includes a first support base and a second support base. The crossbeam assembly includes a first crossbeam and a second crossbeam symmetrically arranged on both sides of the first support base and the second support base. The connecting assembly is located between the support base assembly and the crossbeam assembly and is covered by the first crossbeam or the second crossbeam. The first support base, the second support base, the first crossbeam, and the second crossbeam form a support frame to support the filter plates and other components of the filter press.

[0004] The aforementioned filter press frames have fixed dimensions, are not disassembled, and are integral structures welded or bolted together. Their large size and inability to be disassembled result in high transportation costs and low on-site installation efficiency. To address these issues, a modular frame for vacuum filter press units is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a modular framework for vacuum filter press units to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] In one alternative: the two sets of connecting frames are connected by a set of mounting rods, and the hydraulic locking structure is mounted on the mounting rods.

[0009] In one alternative embodiment: the hydraulic locking structure includes a hydraulic oil pump installed at the bottom of the mounting rod, the outlet end of the hydraulic oil pump is connected to an outlet pipe, the inlet end of the hydraulic oil pump is connected to an inlet pipe, an oil pipe is provided inside the mounting rod, push rods are slidably connected to both ends of the oil pipe, an adjusting rod is connected to the end of the push rod away from the oil pipe, a limiting plate is connected to the end of the adjusting rod extending into the oil pipe, a propulsion chamber communicating with the outlet pipe is provided on the side of the limiting plate away from the push rod, and a contraction chamber communicating with the inlet pipe is provided on the side of the limiting plate away from the propulsion chamber and placed inside the oil pipe.

[0010] In one alternative: the bottom of the end frame is connected to support leg A, the bottom of the connecting frame is connected to support leg C, and the bottom of the support frame is connected to support leg B.

[0011] In one alternative: the support frame is provided with a socket that communicates with the crossbar B.

[0012] In one alternative: the support frame located in the middle has several positioning holes B at both ends.

[0013] In one alternative: the positioning hole A is provided in a plurality of parts and is inserted into the positioning block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The nested design of the insert rod with crossbars A and B in this utility model, and the adjustable insertion position, expands the adjustment range and adapts to filter plates of different specifications of filter presses. The first module, second module and third module work together and can be quickly disassembled and assembled. The second and third modules can be added according to actual needs to improve site adaptability and reduce transportation and storage costs.

[0016] In this utility model, the hydraulic locking structure can adjust the distance between the two sets of adjusting rods, so that the positioning block can be inserted into the corresponding positioning hole A or positioning hole B to achieve quick locking, which facilitates the assembly between modules and supports the rapid expansion of unit components, such as increasing the number of filter layers or connecting multiple units in parallel.
