RO125732A0 - Module for filling cylinders with liquid propane-butane mixture and derivatives and handling process - Google Patents

Abstract

The invention relates to a module for filling cylinders with liquid propane-butane mixture and base derivatives, connected to a LPG station with underground LPG tank and to a handling process. According to the invention, the module consists of a cylinder weighing-correcting device provided with a system of electronic dosage, connected by means of a GEMU type valve (8) to a pump equipping the LPG station and of a device for cylinders emptying-correcting which carries out the corrections and the emptying in case of over-filling the cylinder or occurrence of an error when performing a tightness test, by means of a manual pump-compressor (5). According to the invention, the module handling process consists in opening the GEMU valve, by the command given by the weighing device, which allows a propane-butane mixture to pass towards a filling pistol connected to a gas cylinder, afterwards, when finishing filling the mixture quantity, the weighing device will command the GEMU valve closing.

DESCRIPTION OF THE INVENTION

HOW TO LOAD BOTTLES WITH LIQUID PROPANE-BUTANE MIXTURE AND DERIVATIVES AND HANDLING PROCEDURE

The present invention relates to a cylinder loading module with a mixture of propane - liquid butane and basic derivatives connected to the LPG station - car with a 5 m ³ above-ground LPG container. consists of an electronic weighing-correction device for cylinders which, with the help of a pump - manual compressor, loads the cylinder, measures the propane-butane mixture, and which a draining-correction device for the cylinders makes the necessary corrections and emptying, all by means of fittings , technological pipes and automation elements mounted in an independent metal cabinet (housing).

in the field of loading propane-butane mixture cylinders connected to car LPG stations, the supply is made directly in the vehicle tank, the propane-butane liquid being loaded by the gas distributor from the tank installed for the LPG-car storage and distribution installation; and the amount of gas is measured only by volume.

An easy to deduce disadvantage of this technical solution is that it does not allow the loading of bottles or containers other than those typed and mounted on the vehicle. This tank cannot be moved elsewhere and the gas in it is limited to the volume of the container, without the possibility of weighing and / or further emptying the container.

The problem solved by the invention is that it allows the automatic loading with LPG gas with electronic control, allows the verification of the mass of the loaded cylinder and its manual correction in case of need.

The propane-butane mixture coming from the operating tank (1) is loaded into the cylinder through a cylinder loading module with liquid propane-butane mixture and basic derivatives (2) (fig.l).

The loading module for cylinders with a mixture of propane - liquid butane and basic derivatives according to the invention consists of a metal housing (3) in which there is a device for

-2009-00940-1 9 Ί1- 2089 loading and weighing (4), a loading compressor pump (5) and a drain / correction device (6) (fig.2a and 2b).

The housing is made of metal and is configured as follows:

The floor of the case is a light metal structure, made of aluminum sheet with a drop pattern, and the roof and walls are made of sheet metal, the dimensions of the metal box being: Width: 600 mm Length: 1400 mm Height: 2000 mm (fig.3).

The three walls of the metal cabinet are provided along their entire length, with ventilation grilles (12) of 30 x 30 x 4 cm, corresponding to a theoretical gap (without fillings) of 20 cm height. The housing can be equipped with a luminaire.

The bottle loading and weighing device is equipped with an electronic dosing system and a manual loading valve (7), connected to the pump pressure line (5) by a GEMU controlled valve (8), the pressure can be checked with a manometer (9), and the loading accuracy is guaranteed by the by-pass valve (10) set to the value of 12 bar (fig.l). The charging line in the module is equipped with an oil pressure gauge, 0-25 bar, with a margin of error of 1.6%.

In fact, the bottle weighing device consists of a scale holder (1), on which is placed the actual scale type TON 60 (2) provided with DFWATEX electronic terminal (3), on the scale holder being mounted and pneumatic loading gun holder (4) (fig-4).

The scale will be set for two types of bottles A and B, namely:

type A (o30 cm, p = 30 bar h = 57 cm, V = 26 liters) type B (o30 cm, p = 30 bar h = 145 cm, V = 84 liters)

-0.2 kg

Due to the characteristics of the weighing system, the cylinder and the loading parameters can be configured by computer, with the collaboration of the manufacturer, and during use, the specific loading data can be selected on the operator interface.

The TON 60 table scale measures weights up to 60kg / 20g, is equipped with a 3 meter hose and a support for the supply gun. The weighing instrument is suitable for:

The operation of the scale requires 220 V AC.

The tightness of the BERNER leak detection solution (code 136193) at the test site must be checked for leaks.

The charge pump is a COMAPRO 5/4 ”PC PN25 bar liquid gas pump, or other type with identical parameters, ie:

Q = 45 1 / minute, Δ P = 8, Oex drive motor Eex 230/400 V, 50 Hz, 4KW pressure relief valve, integrated, with factory setting.

Drain / correction device

Emptying (unloading) is required in case of:

1. overloading the bottle

Correction of the overload is carried out on the scale, by opening the ball valve (11) of the manual gas pump (5), by starting the pump by the manually connected loading gun (fig l)

2. error correction detected during the leak test (valve neck, valve closure, valve seal box).

This error is corrected by moving the cylinder to the support of the unloader. The discharge device consists of a support for the steel pipe cylinder (1) with arms (2) (fig.5), a REGO 1/2 ”valve, a 1.1 m flexible hose, and an air pump (manually operated compressor pump) for discharge (5), which is also suitable for discharging the gas phase (manually operated compressor pump) (fig. 1).

The REGO liquid loading valve, size 1/4 ”NPT, type 7901T will be connected to the cylinder positioned on the cylinder holder, with the valve down.

The manual loading (discharge) valve is connected to the suction line of the pneumatic gas pump (5), through which the discharged quantity is transported back to the tank (1) through the by-pass circuit (10) (fig.l) of the system, through a check valve. The non-return valve ensures that the discharge device only allows discharge. A control pressure gauge of 0, 0-25 bar is integrated in the technological circuit for unloading the bottle, respectively for reducing the load. ____

The loading module for the cylinders with propane-liquid butane mixture and basic derivatives is used as follows: The weighing device (computer) of the scale, controls the opening of the GEMLJ valve (8) (fig.l), which allows load (4) connected to the gas cylinder, after which, when the set amount of mixture set is filled, the weighing device (3) (4) (fig.4) will control the closing of the GEMIJ valve.

If an attempt is made to fill the cylinder with more than the permitted amount (programmed for each type of cylinder), the weighing device will command the GEMIJ valve to close.

The advantages of the invention are the following:

allows filling of portable containers with LPG;

allows weighing and correction of the amount of gas in the loaded container; the scale used is a common one, which can also be used for general purposes.

the volume of the bottle loading mode being small, it does not take up much space and can be placed again difficulties where necessary;
