Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail vehicle separating devices are not compact, economical, or low-maintenance due to the need for a discharge blower and associated components.
Innovation Solution
Integration of a Venturi nozzle connected to the discharge opening of the cyclone separator, which uses a constricted section to create a vacuum for particle suction, eliminating the need for a separate discharge blower and reducing the number of moving parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a discharge blower is used to transport separated particles away from the separator housing, then particles can be effectively removed, but the device becomes more complex, larger, and requires more maintenance
Solution Approach 1:
The patent extracts the particle transport function from the mechanical discharge blower and transfers it to the raw air flow itself. The raw air flow is diverted through a side channel that connects to the discharge opening, using the kinetic energy of the air flow to carry particles away without requiring a separate mechanical blower device.
Solution Approach 2:
The raw air flow serves multiple functions: it provides cooling air to the machine compartment, and simultaneously serves as the transport medium for removing separated particles from the separator housing. This multi-functionality eliminates the need for dedicated particle transport equipment.
2Reliability
If a discharge blower is mounted to suction particles from the separator housing, then particles are transported away effectively, but the device occupies more space
Solution Approach 1:
The patent merges the particle transport function with the existing raw air flow path. The side channel integrates the discharge opening into the existing air flow system, combining particle removal with the cooling air supply function and eliminating the need for separate particle transport equipment.
Solution Approach 2:
The raw air flow serves itself by simultaneously performing cooling and particle transport functions. The air flow that would otherwise only cool the machine compartment now also carries away separated particles, making the system self-sufficient without additional active components.
3Reliability
If a discharge blower with moving parts is installed, then particle suction is achieved, but maintenance requirements increase
Solution Approach 1:
The patent replaces the mechanical discharge blower system with a pneumatic system using the raw air flow. By substituting mechanical moving parts with fluid dynamics (the air flow through the side channel), the system eliminates wear, friction, and mechanical failure modes associated with blower motors and impellers.
Solution Approach 2:
The raw air flow automatically performs particle transport without requiring external power sources or mechanical actuation. The system uses the existing pressure and flow characteristics of the cooling air to create self-sustaining particle removal, eliminating maintenance needs for particle transport mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a more compact, economical, and lower-maintenance separating device by utilizing the raw air flow to generate the necessary vacuum within the Venturi nozzle, reducing space requirements and maintenance needs.
Implementation Method 1
The discharge opening is connected to a constricted section of a Venturi nozzle for suctioning away an exhaust air flow to which discharged particles have been added
Implementation Method 2
The raw air flow flowing into the separator cyclone is in each case there displaced by guide vanes into a rotational movement, as a result of which the particles being carried in the flow are accelerated toward pipe walls of the separator cyclone by the centrifugal force experienced
Implementation Method 3
the cleaned air is discharged at the other ends of the separator cyclone as a clean air flow, while due to gravity the separated particles fall down from the discharge windows onto the floor of the separator housing

AI summary
A rail vehicle or locomotive includes a machine compartment, a cooling air flow system supplying the machine compartment, and a separating device separating particles from the air flow. The separating device includes a cyclone separator, a raw air channel feeding a raw air flow with particles to the separator and a clean air channel leading a clean air flow away from the separator. The separator has a box-shaped housing having a plurality of cyclones penetrating the housing for separating particles from the raw air flow into the housing and a discharge opening discharging separated particles from the housing. The discharge opening is connected to a constricted section of a Venturi nozzle suctioning an exhaust air flow having discharged particles. The Venturi nozzle is connected to the raw air channel by a branching side channel. The vacuum at the discharge opening suctioning the exhaust air flow is compact and economical.
