Shared Cross Beam Screen Module for Mineral Processing

Solution Overview

Problem

Existing mineral material screening apparatuses are excessively high and heavy due to the need for multiple decks with large spaces between them, complicating handling, transport, and maintenance, and requiring significant material and labor for production and maintenance.

Innovation Solution

A screen module design that allows multiple decks to share cross beams, reducing the height and weight by eliminating unnecessary space between decks, with support structures and adjustable longitudinal supports enabling easier assembly and maintenance, and using interchangeable wear plates to minimize material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If each screen deck is fixed on its own cross beams with large spaces between decks, then screen mesh change is possible, but the screening apparatus becomes very high and heavy

Engineering Contradiction:

Improvescreen mesh changeabilityVSAvoidscreening apparatus weight

Core Design Contradiction:

Ease of operationVSWeight of stationary object

Solution Approach 1:

Multiple screen decks are fixed to the same cross beams, merging the support structures of multiple decks into a single shared structure. This eliminates redundant cross beams and reduces the overall weight of the screening apparatus while maintaining the ability to change screen meshes on each deck independently

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cross beams serve multiple functions by supporting multiple screen decks simultaneously. Instead of each deck having dedicated cross beams, the same cross beams universally support several decks, reducing material usage and apparatus weight

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If each screen deck is fixed on its own cross beams with large spaces between decks, then screen mesh change is possible, but the screening apparatus height increases

Engineering Contradiction:

Improvescreen mesh changeabilityVSAvoidscreening apparatus height

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

Multiple screen decks are fixed to the same cross beams, merging the support structures of multiple decks into a single shared structure. This eliminates redundant cross beams and reduces the overall weight of the screening apparatus while maintaining the ability to change screen meshes on each deck independently

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention reorganizes the spatial arrangement by allowing decks to share cross beams in the vertical dimension, reducing the height required for each deck level. This dimensional optimization allows closer spacing of decks while maintaining accessibility for maintenance

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Stability of the object's composition

If own cross beams are required for each screen deck, then each deck is structurally independent, but much material and work is required for production and maintenance

Engineering Contradiction:

Improvedeck structural independenceVSAvoidproduction and maintenance work

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

Multiple screen decks are fixed to the same cross beams, merging the support structures of multiple decks into a single shared structure. This eliminates redundant cross beams and reduces the overall weight of the screening apparatus while maintaining the ability to change screen meshes on each deck independently

AI summary

A screen module for mineral material includes support structures such as cross beams or longitudinal beams for fixing the screen module to a body of a mineral material processing apparatus, and for fixing an upper screening means above the support structures, and lower longitudinal supports which are fixed below the support structures for supporting a lower screening means below the lower longitudinal supports. A processing apparatus and a processing plant.
