TECHNICAL FIELD The present invention relates to a method for dissolving and supplying a powdery drug to be supplied to a machine and an apparatus used for the method.

[0002]

2. Description of the Related Art Conventionally, when performing processing such as dyeing in a cloth processing machine such as a dyeing machine or a package processing machine, powdery chemicals such as dyes and pigments, bleaching agents, surfactants and scouring agents are used. Is used. If such powdered chemicals are introduced into the processing machine as it is, dissolution or dispersion becomes insufficient and unevenness in processing occurs. For this reason, a charging tank and stirring equipment are provided separately from the processing machine, and these equipment are used to adjust the powdered chemical once dissolved in a solvent solution and transport this adjusted chemical solution to the installation location of the processing machine. Supply is being done.

FIG. 9 shows an example of such a processor. That is, this apparatus is a so-called liquid flow type cloth processing machine, 41 is a stay tank in which the cloth 50 stays, and 42 is a transfer section for transferring the cloth 50. The stagnation tank 41 and the transfer section 42 are installed substantially in parallel, and connected and communicated at both ends to form a circulation processing passage for the fabric 50. Reference numeral 43 denotes three liquid suction portions provided at the bottom of the storage tank 41, and the processing liquid sucked from these liquid suction portions 43 circulates to the nozzle 44 via the pump 45 and the heat exchanger 46. It circulates by way 47.
Reference numeral 48 denotes a chemical tank for supplying a chemical to the processing machine. The chemical in the chemical tank 48 is supplied to the processing machine from the suction side of the pump 45 of the processing liquid circulation path 47 via the pump 49. It has become.

[0004] When a chemical solution serving as a processing liquid is additionally supplied to the processing machine, as described above, a powdery chemical such as a dye is converted into water or the like by a dissolving facility or the like provided separately from this apparatus. Is dissolved in a chemical solution, transported to a place where the processing machine is installed, and transferred to the chemical solution tank 48.

[0005]

However, in the above-mentioned method, equipment for dissolving the powdery drug and adjusting the chemical solution is required separately from the processing machine, and a space for installing the equipment is required. Is also required. In addition, not only is the work of adjusting and transporting the chemical solution necessary, but also the charging tank, stirring device,
A number of incidental operations such as cleaning and maintenance of transport containers are also required. Furthermore, since the chemical solution is transported and transferred, the chemical solution loss is also large. For this reason, equipment costs, personnel costs, consumption of chemicals, and the like become enormous, which is a major factor in raising processing costs. In addition, there is also a problem that the chemical solution scatters around during the adjustment, agitation, and transportation to contaminate the working environment. In addition, there is a problem in that the chemical liquid remains in the charging tank or the stirring device, and the residual chemical liquid is mixed with the chemical liquid to be adjusted thereafter, thereby lowering the purity. In addition, there is a considerable time gap between the preparation of the chemical solution and the actual treatment by contacting with a cloth or the like, and particularly, a temporal change such as a reactive dye or an acid direct dye is caused. In the case of a large chemical solution, the properties of the chemical solution change during that time, causing inconvenience such as causing unevenness or insufficient treatment.

[0006] In order to solve these problems, it is desirable to feed the powdered chemical directly into the processing machine.
As described above, if the powder is directly charged, the dissolution or dispersion of the powdered drug is insufficient, and uneven treatment or insufficient treatment occurs. As described above, a feeding method that can directly charge a powdery drug and sufficiently dissolve and disperse the drug has not been developed at present.

The present invention has been made in view of such circumstances, and it is possible to supply a processing agent by dissolving and dispersing a powdered drug directly, and to sufficiently dissolve and disperse the same. It is an object of the present invention to provide a method for dissolving and supplying a powdery drug capable of producing a solution and an apparatus used therefor.

[0008]

In order to achieve the above object, the present invention provides a method for dissolving and supplying a powdery drug, comprising the steps of: circulating a processing solution through an external circulation pipe provided with a pump; In the method for processing textile products, powdery chemicals such as dyes and auxiliaries are charged into a charging tank configured to be hermetically sealed, and a part of the processing liquid is taken out from the pump discharge side of the circulation pipe. The treatment liquid is introduced as a swirling flow into the charging tank to dissolve and disperse the powdered drug into a drug solution, and the drug solution is diluted and supplied to the pump suction side of the circulation line via a drug solution supply pipe. And, a part of the treatment liquid is taken out from the pump discharge side of the circulation pipe and is returned to the chemical supply pipe, and at a communication portion between the reflux pipe and the chemical supply pipe, the reflux treatment liquid is downstream of the chemical supply pipe. Side, and the The Ekuta action, dissolution of the chemical with the upstream side of the chemical liquid accompanying the suction is summarized in that which is adapted to facilitate dispersion.

Further, the powdery drug dissolution supply apparatus of the present invention can be hermetically sealed in an apparatus for processing and processing textile products in a processing tank by circulating a processing liquid through an external circulation pipe provided with a pump. A charging tank into which powdery chemicals such as dyes and auxiliaries are charged, a processing liquid introducing pipe branched from the pump discharge side of the circulation pipe and communicating with the charging tank, and a processing liquid introducing pipe A swirl flow introducing nozzle provided in a communication portion between the charging tank and the charging tank to introduce a processing liquid as a swirling flow to dissolve and disperse the powdered medicine in the charging tank; A liquid supply pipe connected to the pump, and a return pipe branched from the pump discharge side of the circulation pipe and extending to the liquid supply pipe. A communication section between the return pipe and the liquid supply pipe is provided with a reflux treatment liquid. To the downstream side of the chemical supply pipe. Injection to dissolve the drug solution with the upstream side of the chemical liquid accompanying the suction by the jet, is summarized as providing the ejector means to promote dispersion.

That is, according to the present invention, a part of the processing liquid is taken out from the pump discharge side of the circulation pipe and introduced into the charging tank.
The powdery chemicals charged into the charging tank are dissolved and dispersed with the introduction processing liquid to be a chemical liquid, and the chemical liquid is diluted and supplied to the pump suction side of the circulation pipe via the chemical liquid supply pipe. Therefore, a powdery medicine can be directly introduced, and the powdery medicine can be dissolved and supplied to the processing machine as a chemical liquid without using a conventional medicine adjusting equipment. For this reason, equipment for adjusting the chemical solution is not required, and the installation space is also unnecessary. Further, the chemical solution adjusting operation, the transporting operation, and various operations associated therewith become unnecessary. Further, no chemical solution is transported or transferred, so that there is no chemical solution loss. For this reason, equipment costs, personnel costs, consumption of chemicals, and the like are reduced, and processing costs can be significantly reduced.
In addition, the chemical solution does not scatter to the surroundings, the working environment is improved, and the purity does not decrease due to mixing of the residual chemical solution. In addition, since the powdered drug is dissolved and converted into a chemical solution, it is processed in a very short time by contacting with a cloth or the like. Therefore, even when a reactive dye or an acidic direct dye is used, the property of the chemical solution changes before the treatment. As a result, uneven processing and insufficient processing do not occur.

Further, according to the present invention, first, the treatment liquid is introduced into the charging tank as a swirling flow, and the powdered drug in the charging tank is dissolved and dissolved.
Disperse to make a drug solution. Then, when supplying this chemical solution to the pump suction side of the circulation pipe, a part of the processing liquid is returned to the chemical supply pipe from the pump discharge side of the circulation pipe, and at the communication portion between the reflux pipe and the chemical supply pipe, The reflux treatment liquid is jetted toward the downstream side of the chemical supply pipe, and the ejector action by the jet flow sucks the chemical at the upstream side and promotes the dissolution and dispersion of the chemical. As described above, a vortex is generated in the charging tank by the swirling flow of the processing liquid, and the powder is dissolved and dispersed by stirring the charging tank by the vortex. Then, the obtained chemical liquid is further dissolved and dispersed by an ejector action by the jet flow of the processing liquid. Therefore, by performing the above-described two-stage dissolution and dispersion, the poor dissolution which has been regarded as a problem in the method of directly charging the powdered drug does not occur, and the powdered drug is sufficiently dissolved and dispersed. Become. Therefore, high-quality stable processing can be performed without processing unevenness or processing shortage.

In addition, the powdered drug is once dissolved in a charging tank to form a drug solution, and the drug solution is diluted with a reflux treatment solution in an ejector section, and the diluted solution is supplied to a pump suction side of a circulation pipe to provide a large amount of circulation. It is diluted by merging into the processing solution. As described above, a high-concentration chemical solution in which a powdery drug is dissolved can be supplied to a processing machine as a processing solution diluted to a predetermined concentration. For this reason, for example, unlike the case where the powdered drug is directly introduced into the circulation pipe, the extremely high concentration of the drug solution does not partially circulate, thereby causing processing unevenness.

In the present invention, when the processing liquid is introduced into the charging tank as a swirling flow, the introduced processing liquid is alternately or simultaneously introduced as a right swirling flow and a left swirling flow from two nozzles. Can generate not only a vortex but also a turbulent flow in the charging tank. As a result, the stirring action becomes stronger, and the dissolution and dispersion of the powdered drug are further promoted, so that a more stable treatment can be performed.
