Description

Powder injection apparatus with guide bane

The present invention relates to a powder chemical injection device that is installed in a water purification plant of water and sewage facilities or a water purification vessel, and injects powder chemicals such as activated carbon into water.

Recently, as the environment and water quality are severely polluted, it is difficult to remove contaminants using a general water purification method, and after using a high-level water purification process to use and drink water, it is used as a general method based only on aggregated precipitation filtration and disinfection. The water treatment process has limitations in effectively controlling taste, odor, disinfection by-products, and trace harmful organic substances.

In other words, contamination due to excessive use of pesticides and organic chemicals, mold odor caused by eutrophication and chemical odor caused by factory drainage, contamination caused by disinfection by-products generated during chlorine treatment, and anionic surfactants caused by the use of synthetic detergents In order to remove contaminants such as residues of water, a lot of purification processes using activated carbon are used.

In particular, activated carbon is used as a process for removing carcinogens such as chlorine disinfection by-products such as non-degradable organic materials, trihalomethane (THM), benzene (Benzene), and toluene, as well as removing taste, smell, or color. The scope of its use is gradually expanding.

There is a porous structure having high adsorption performance inside the activated carbon made by carbonizing coconut shell, coal, wood, etc. at a high temperature, and these innumerable pores are used to remove adsorbable harmful substances.

Granular activated carbon, powdered activated carbon, biologically activated carbon, etc. may be used as a method for treating water using activated carbon, and currently, a water purification process using powdered activated carbon is widely used.

In order to purify water using activated carbon in this way, a large amount of activated carbon must be stored in a silo, etc., and the stored activated carbon is combined with moisture in the air to become lumped or aggregated to form agglomerates, so activated carbon is smooth. It cannot be supplied, and it causes serious obstacles to the operation of water purification facilities.

Therefore, a variety of conventional techniques have been used to prevent the solidification of activated carbon or a device for automatically and constantly supplying activated carbon stored in a silo, but many problems have occurred.

Typically, when the powdered activated carbon is put into the activated carbon storage device, the powder is blown away, and when the powdered activated carbon is stored for a long period of time, the activated carbon cannot be supplied smoothly due to solidification or agglomeration inside the silo or the melting tank. A hole phenomenon in which only a portion of the activated carbon is supplied irregularly occurs, causing a problem that it is impossible to automatically supply the powdered activated carbon constantly.

As a technique for solving this problem, in the "dust collection device capable of collecting dust" (Korea, Registered Patent Publication No. 10-0635531, Patent Document 1), a hood is installed on the upper side of the storage tank, and the venturi dissolution tank and By connecting the hood and the feeder to the connected conduit, the collected dust was supplied to the Venturi melting tank so that the dust could be easily processed.

However, in the same manner as in Patent Document 1, the hood and the dissolving tank are not blocked, and the structure is in communication. When the humidity rises due to the water inside the dissolving tank, the moisture naturally rises to the space where the powder medicine is stored in the vertical tube and hood. There is a problem in that moisture is adsorbed to the powdered medicine inside the storage tank and clumps.

In addition, in order to draw dust in the storage tank through the negative pressure generated in the Venturi dissolution tank, it is necessary to take a structure in which external air can be naturally introduced into the storage tank, which means that external air is introduced into the storage tank and moisture is introduced together. There is a problem in that powdered chemicals such as activated carbon in the storage tank are fixed by moisture.

In addition, when supplying the powdered drug into the storage tank, the cover is opened and supplied at the top of the storage tank. As the powdered drug is supplied with the lid open, dust is scattered both inside and outside, contaminating the surrounding environment. In particular, there was also a problem that powdered chemicals accumulate like acid in the center of the storage tank.

Hereinafter, a powder medicine injection device equipped with a guide van of the present invention will be described in detail through the accompanying drawings.

The storage hopper 10, which is a component of the present invention, is eccentrically connected to a supply pipe 11 through which powder chemicals such as activated carbon are supplied to one side, as shown in FIG. 2, and the powder medicine supplied from the supply pipe 11 It is made to be stored inside.

To this end, the wall surface of the storage hopper 10 of the portion where the storage hopper 10 and the supply pipe 11 are connected is perforated with holes.
