The present invention relates to a drug admixture for supplying and mixing the drug to the raw water used in the water purification plant or swimming pool.

More specifically, the liquid inlet pipe is formed integrally to communicate with each other, the liquid inlet pipe in which the liquid is introduced into the front and rear of the mixing tube forming the mixing chamber and the liquid discharge pipe in which the chemicals are discharged. The chemical spray pipe is installed to face backwards, and in the mixing chamber of the mixing pipe, a chemical flying piece is installed in front of the chemical injection pipe, and the chemical sprayed backward from the chemical spray pipe collides with the chemical flying piece and is scattered, It is to be evenly mixed with the liquid supplied through the inside of the mixing chamber, a plurality of discharge holes through the partition is installed in the interior of the partition and the plurality of divided pieces in equal angle to install the inner circumference of the liquid inlet pipe in front of the partition wall The liquid mixed with the chemicals is slightly delayed by the partition wall, so that the liquid is mixed more uniformly, It is intended to provide an improvement such that the divided is discharged through the liquid discharge pipe ball drug mixing device without collision to.

In order to disinfect raw water in a water purification plant or swimming pool, or to aggregate the foreign substances contained in raw water, chemicals such as disinfectant or flocculant are injected.The raw materials are introduced through pipes before supplying raw water to the intake or swimming pool. In this case, the injected chemicals should be mixed evenly with the raw water to maximize the efficiency of the injected chemicals.

As a conventional apparatus for mixing and mixing the drug into the raw water as described above, the domestic Utility Model Publication No. 1999-8182 "Chemical conversion device of water purification plant" and the Registration Utility Model No. 113114 "coagulant injection device" And Utility Model Registration No. 224737, "Mixed Paper Chemical Injection Device," and Registration Utility Model No. 275014, "Drug Injection and Mixing Device."

Korean Utility Model Publication No. 1999-8182 "Chemical cyclization device of a water purification plant" is simply a cylinder inside the raw water pipe to which the raw water is supplied, or vertically installed injector pipe with a plurality of injection holes through the periphery of the injection pipe The chemical supplied through the (spray hole) is mixed with the raw water passing through the raw water pipe.

However, this is simply because the chemical injected through the cylindrical injection pipe is a problem that is supplied to the water intake or swimming pool in a state that is not uniformly mixed with the raw water passing through the raw water pipe rapidly, the minute perforated in the outer periphery of the injection pipe Even if the drug is injected through the hole is mixed rather easily than the drug is simply injected through the cylindrical injection tube, but there is also a problem that the drug is not evenly mixed.

Registered Utility Model No. 113114, "Aggregating agent input device", the upper and lower sides of the container formed of a reduction tube is formed in communication with the chemical inlet provided with a measuring vessel and a valve, and supplies compressed air to the upper and lower sides from the inside After installing the medicine vortex pipe and compressed air induction pipe, measure the amount of medicine by the measuring container and put it into the inside of the container through the chemical inlet. Compressed air is injected through the pipe to raise the chemicals by the pressure of the compressed air to be discharged through the chemical induction pipe installed on the upper side of the upper reduction pipe, and supplied through the chemical and water induction pipe discharged to the chemical induction pipe The water (raw water) is to be supplied to the dissolution tank at the same time through the nozzle.

However, this is caused by the compressed air pressure while filling the container with the drug, there is a problem that can not precisely control the discharge of the drug, the water (raw water) and the chemical through the nozzle installed in the dissolving tank at the same time to be mixed. Therefore, there is a problem that the drug is not evenly sprayed in the raw water to mix.

Utility Model Registration No. 224737 "Mixed paper chemical input device" is formed in the shape of the venturi tube narrowest in the center by forming a reduction tube and expansion tube between the inlet tube and the outlet tube of a constant size. And through the chemical discharge port connected to the chemical storage tank at the top end of the inclined tube, the chemical supplied through the chemical discharge port is discharged when the raw water flowing into the inlet pipe is discharged through the reduction tube and the expansion tube. It is to be done.

However, this is because the drug is simply discharged by the pressure of the raw water discharged when the raw water flowing into the inlet pipe is discharged into the outlet pipe, there is a problem that can not discharge the drug uniformly, Since it is discharged to the upper side (upper surface), there is a problem in that the chemicals may not be mixed smoothly with the raw water and may not be evenly mixed.

Registered Utility Model No. 275014, "Drug input and mixing device", is provided with a hopper at the top of the chemical mixing vessel and a spiral tube is installed at the outlet of the hopper inside the medicine reservoir, but the discharge of the hopper and the top of the spiral tube The water supply pipe is connected between the hopper and the inside of the hopper by installing a feed screw that is operated (rotated). The chemical is introduced into the hopper and the feed screw is rotated by the motor. When it is supplied, the medicine filled in the hopper is supplied to the spiral tube by the transfer screw and mixed with the water supplied through the water supply tube to be discharged to the chemical reservoir through the spiral tube, and the chemical and water filled in the chemical reservoir are diluted. The medicine is supplied to a predetermined place (or device) through a discharge pipe installed at the bottom of the medicine reservoir.

However, this simply mixes the drug with the water to be supplied, so the amount (drug) of the drug cannot be precisely and uniformly set or adjusted so that the concentration of the drug is different, and the diluted drug is stored in the medicine reservoir primarily, so If the mixed (diluted) drug is not completely melted, it sinks on the bottom of the medicine reservoir and is stacked inside, which causes the drug to be discharged without setting the chemical concentration precisely and uniformly. There is a problem that can not be mixed smoothly and evenly with the diluted chemical solution.

In particular, when the chemicals do not mix evenly with the raw water, as in conventional admixtures, there is a problem that the disinfection effect or the cohesive force to flocculate the sludge is reduced to significantly reduce the purification efficiency.

The present invention is to provide a drug admixture further improved to solve the above problems.

The present invention is integrally formed to communicate with each other, the liquid inlet pipe in which the liquid is introduced into the front and rear of the mixing tube forming the mixing chamber and the liquid discharge tube is mixed and discharged to the chemical discharge tube, the front and rear is open type, Install the spray pipe to the rear and install the chemical scattering piece in the mixing chamber of the mixing pipe in front of the chemical injection pipe, and install the bulkhead through which the plurality of discharge holes are perforated in the rear of the mixing chamber An object of the present invention is to provide a chemical mixing device in which a plurality of divided pieces are installed at an equal angle to divide the inside of the pipe.

Another object of the present invention, by supplying the chemical flying piece in front of the chemical injection pipe installed in the liquid inlet pipe to face the rear, the chemical sprayed from the chemical injection pipe is scattered while colliding with the chemical flying piece flying medicine supply pipe It is to be evenly mixed with the liquid supplied through the through-hole, through the plurality of discharge holes through the partition wall installed in the rear of the inside of the mixing chamber and a plurality of divided pieces of different lengths on the inner peripheral surface of the liquid inlet pipe in front of the partition wall When the mixed liquid is delayed slightly by the partition wall and collides with each other, the vortex phenomenon occurs and the mixture is more uniformly mixed. At the same time, the liquid is divided by the split pieces and sprayed into the liquid discharge pipe through the discharge hole without colliding again. It is to provide an improved drug admixture to be mixed.

Still another object of the present invention is to form the inclined surface protruding obliquely toward the outer center of the mixing tube formed between the liquid inlet pipe and the liquid discharge pipe so that the liquid is discharged without delay in the corner portion It is possible to prevent the chemicals from stacking on the corners of the mixing tube, and the liquid (raw water) is supplied to the mixing tube extending from the narrow liquid inlet tube to be scattered by the pressure so that the injected chemical is more easily and smoothly. Provides a chemical mixing device that allows the liquid (raw water) mixed with the chemicals to be quickly discharged from the wide mixing tube to the narrow liquid discharge tube to enhance the discharge power It is.

Another object of the present invention is to keep the concentration of the chemicals mixed in the liquid (raw water) precisely and uniformly, thereby preventing the disinfecting effect from falling or the cohesive force that aggregates the sludge, thereby reducing the purification efficiency. To provide a drug admixture that can be.

Since it collides with the liquid (raw water) flowing through the pipe (2), the medicament contained in the liquid is kept evenly mixed, and narrow when the raw water is discharged to the discharge hole (8) of the partition wall (7) Since it is scattered as it is discharged through the hole, the contained medicines are maintained in a more evenly mixed state, and the liquids are evenly mixed and the liquid discharged into the liquid discharge pipe 4 is supplied to the next step.

In particular, the front and rear surfaces of the mixing chamber 5 are inclined surfaces 3-1 when the liquid flows from the liquid inlet tube 2 into the mixing tube 3 and is routed from the mixing tube 3 to the liquid discharge tube 4. ), The liquid flows in and out more quickly.

Although specific embodiments have been described in the present invention, it will be apparent to those skilled in the art that various modifications and changes are possible within the technical scope of the present invention, and such modifications and modifications belong to the appended claims.

Chemical mixing apparatus according to the present invention, the front and rear is open type and the liquid inlet tube in which the liquid is introduced into the front and rear of the mixing tube forming the mixing chamber and the liquid discharge tube in which the drug is mixed and discharged integrally formed integrally with each other, In the liquid inlet pipe, the chemical injection pipe is installed to the rear, and the mixing chamber of the mixing pipe is installed with the chemical flying pieces in front of the chemical injection pipe, and inside the mixing chamber, a partition wall having a plurality of discharge holes is installed. In the inner circumferential surface of the liquid inlet pipe at the front of the partition wall, a plurality of split pieces are installed at an isometric angle, and the chemical spray pipe is installed in front of the chemical injection pipe installed in the liquid inlet pipe to face the back. The chemical sprayed backward from the gas is scattered and collided with the chemical scattering pieces and mixed evenly with the liquid supplied through the chemical supply pipe. Since the plurality of discharge holes pass through the partition walls provided inside the mixing chamber and the plurality of split pieces are installed on the inner circumferential surface of the liquid inlet pipe at the front of the partition wall, the liquid mixed with chemicals is slightly delayed by the partition walls and the discharge holes of the partition walls. Since the drug is discharged while being scattered when passing through, the drug is discharged in a more uniformly mixed state, and the front and rear surfaces of the mixing pipe formed between the liquid inlet pipe and the liquid discharge pipe are inclined to protrude outwardly to the center. Therefore, the liquid can be discharged without delay at the corners to prevent the chemicals from being stacked at the corners of the mixing tube, and the liquid (raw water) can be quickly discharged to enhance the discharge power. Disinfection effect by maintaining precise and uniform concentration of chemicals mixed in liquid (raw water) It is possible to improve the purification efficiency by strengthening the cohesive force.
