Piston tank with externally guided piston and hose pump

Abstract

Claim of protection: To use a peristaltic pump to pump a liquid in and out of a pressure-resistant pipe with an axially movable, externally guided piston, and to store it.

Description

1. Purpose

[0001] A piston tank with externally guided pistons and a peristaltic pump (KTmawgKuSP) is used to receive, store, and discharge liquids. Hereinafter, it will be referred to as a piston tank. 2. Innovation

[0002] A peristaltic pump is used to pump liquids in and out of the piston tank with an externally guided piston. Compared to previous technologies, this eliminates the need for an axially moving spindle (threaded) and its peripherals, or similar linear systems. The peristaltic pump allows for highly precise delivery volume, a self-locking overall system, and simple sealing. 3. Structure and operating principle

[0003] The peristaltic pump is attached to the base of the tank. One end of the hose connects to the inlet in the pressure-resistant pipe (tank), while the other end leads to the liquid. Inside the pressure-resistant pipe is an axially movable piston, guided by its outer wall. A seal connects the piston to the pressure-resistant pipe. The liquid is fed through the inlet in the base. During filling (flooding), the peristaltic pump transfers the liquid into the tank, pushing the piston axially away from the base by the incoming liquid. During emptying (draining), the peristaltic pump transfers the liquid out of the tank, pulling the piston axially towards the base by the outgoing liquid. When the peristaltic pump is stationary, the amount of liquid in the tank remains unchanged.The two mechanical end positions of the piston are detected via end position sensors and processed accordingly by the control electronics.

[0004] The parts mentioned and described are in the appendix. Fig. The diagram shows the electrical power cables and signal lines, but not the actual cables. The piston tank is scalable in both length and diameter. 4. Control

[0005] The control system processes the end-position sensors and input commands electronically and, according to the specifications, controls the power level of the peristaltic pump to change the fill level of the piston tank within the possible parameters, thereby moving the piston in an axial direction. The control system is not part of the utility model protection. 5. Power supply

[0006] The required power supply can be provided variably via mains adapter, rechargeable battery, or standard battery. The power supply is not part of the utility model protection. 6. Application examples a) The piston tank can be used in submarine vehicles and drones (manned and unmanned), as well as (remotely controlled) model submarines for static diving and / or attitude trimming, both individually and in combination with several. b) Another possible application is in the repair, maintenance and cleaning of systems and equipment, to extract or introduce liquids.
