Description
Chemicals, for example be used to wash and so on, generally be to provide by some mode.At first this chemicals can provide the material component of joining that is suitable for last use to concentrate with compound mode.The problem of this distribution method is to be applicable to the multiple mixture of different purposes and owing in the chemicals of any last use, all have quite a large amount of moisture to exist, thereby, in order to store these chemicals demand sides to a large amount of volume and weights.
A method that solves the volume and weight problem provides the chemicals of conc forms, allows last user can suitably explain this solution as required thus.As if but on the other hand, this method can arouse attention, because under washing situation commonly used, it is inconvenient reaching desired accurate dilution, this explanation may have problems.Too dense or too rare solution may be unsuitable equally.
Different mixing arrangements is known on technology, and at United States Patent (USP) 2,955, has provided this device substantially in 726,3,977,682,3,251,508,3,951,311,3,960,295 and 3,268,119.Though how many these patents are effectively finishing aspect its intended purposes,, do not have one piece can be suitable for using the product that mixes multiple composition at last in these patents, and aspect expense, be feasible the user.Particularly, do not have one piece to record designed the taking out of the present invention through multistage pump and single-stage pump (draw-through mani-fold and single pump), be not documented in hereinafter yet described in and other inventive features of requiring.
Obviously, desiredly in daily chemical processing plant (CPP), implemented in large quantities with all mechanical devices.But this mechanical device is very expensive, and in fact complicated more than the mechanical device of the preparation use of narrating hereinafter.
Therefore, an object of the present invention is to provide a kind of can be with the device for formulating of accurate mode mixed chemical component, the amount of the desired every kind of component that combines with suitable dilution water or other solvents accurately is provided, and this water or other solvents all are basic to all chemical constituents.
Another object of the present invention provides a kind of quite compact, and is can cheap a kind of chemicals hybrid system of making, so that can be suitable for last situation about using.
The present invention mixes different super dense solvent fluids for being used to, and with flush fluid, designs with the product that forms last use.Use therein term " flush fluid " briefly is defined as and comprises the fluid that is used to dilute various batching solvents.For example, in the concrete scheme of the various flush fluids of use that will discuss hereinafter, water is the flush fluid that is used to dilute various liquid solvents.This flush fluid also can be the mixture of various furnish components, for example, can be the mixture of alcohol-water.
In the other application that may contain oil base, can recognize: a kind of liquid for example, mineral spirits can be a flush fluid, this flush fluid can be used for mixing and diluting various paint pigments, or suchlike various component.Obviously, the meaning that is not meant alkali that here defines of term " solvent (ba-se) " (translator annotates: " alkali " and " solvent " is same word " base " in English, thereby this explanation is arranged).
Pipeline carry be from the container that is full of various key components in the linear pattern mode, the dispensing branch of optimal arrangement flows.
The difference arrangement that can recognize other also is spendable, for example, and annular array.Be controlled at the inlet of chemicals component and the circulation between the central passage with electrically-energized solenoid.Pump is connected the logical port of export in center, and wish it is a kind of reciprocal reed pump (oscilla-ing leaf spring pump), this pump aspirates selected furnish component, make it by arm to the arm outlet, subsequently through measuring, mixing with pressurised stream (or selected flush fluid) in the known fixed ratio through the amount measured.
Rinse mouth and the solenoid that is connected are arranged on the other end of the dispensing branch of outlet; The ingredients mouth of various components is arranged between these two.The water intaking valve solenoid that is connected with Flow-rate adjustment is connected to the inlet of outlet stool.The cleaning hose that describes in detail above be connected to and the outlet stool of the adjacency that enters the mouth on.This cleaning hose is equipped with check valve, directly flows to outlet stool by cleaning hose to prevent reverse liquid stream from dispensing branch.
Discharge pipe and outlet stool adjacency that check valve is arranged.Delivery pipe at one end communicates with atmosphere, and this valve only allows liquid stream to flow into dispensing branch from atmosphere.At last, above-mentioned delivery side of pump is to be connected on the outlet stool.
Discharge one-way valve on outlet stool plays an important role.After pump is turned off,, there is quite a large amount of fluids to remain in outlet stool and the preparation pipe usually at the end of preparation circulation.Because that yes is fluid-tight for this pipeline, so when the fluid that left behind can be maintained to next formulated fluids, undesirable or incompatible composition might be mixed together.By check valve is installed, when reducing the pressure of outlet stool, air can be flowed in outlet stool and the preparation pipe, therefore, the fluid residue of a great deal of that is deposited in here can be emitted, so that the not mixing that can be harmful to.The particular arrangement of outlet stool part is important, and arrangement like this can make this system carry out best running.Especially, the setting at the unidirectional drain valve of air of the downbeam of cleaning hose inlet makes cleaning hose can accept the fluid that comes out from feed water valve, and is not mixed with air.In other words, the water supply that enters the continuous pressurization of outlet stool provides the water that is not mixed with air to enter cleaning hose all the time, and this is important for keeping normal liquid stream by this pipe.The air bleeder valve that is provided with on the countercurrent direction of pump discharge helps this discharging effect.
Check valve equally also is installed between water solenoid and the outlet stool, turns back to the water source that possibility hydraulic pressure descends to prevent liquid stream.
Assembly control system carries out cycling to provide to heterogeneity, in order that make various components reach best mixing and preparation.For example, if with pump suction component A2 second, secondly before solenoid, supply with water several seconds by cleaning hose, then, be transferred to B component, through 2 seconds, the measure of this cycling makes component A and B component, can only mix by rights.For example, although component A and B component finally can be, compatible with the form of dilution, and can be miscible,, when superelevation was dense, it was not rare that these components are not easy miscible situation yet.Therefore, and if then just add B component after component A, the mixture of the two is arranged in dispensing branch, and the pump suction turns to the high viscosity gel, this gel just can not accurately be sucked like this.If at first send component A, water flushing before pump suction B component is diluted to the degree that can suitably mix to various components then, at the downbeam of pump, mixes so that can accurately measure its content.In addition, it shall yet further be noted that the last solenoid of cycle period opening in preparation, this wash solenoid, can make water wash arm and pump and plays the suitable dilution effect.This flushing is the part of formulation operations, and has got rid of any artificial cleaning fully at the preparation intercycle.
The arrangement of controlling organization in order that have only when this valve be when opening simultaneously, open all the time for one in the solenoid valve of dispensing branch.A kind of like this arrangement can be full of discharging and dispensing branch all the time with certain liquid.This constant continuous filling can continuously move pump, and provides a kind of high-precision suction and measuring system with constant speed thus.
Though only disclosed a kind of embodiment of cleaning chemicals of making, compounding system of the present invention all suits to other other any application.For example, this system can be used to make the composition of various chemicals.The simplicity of native system can be suitable for final use, and the accuracy of system has enlarged it can applicable scope.
