Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a disinfectant molded product dissolver, and more particularly to a disinfectant molded product dissolver that sprays water onto a disinfectant molded product to dissolve it. The disinfectant molded product dissolver of the present invention can be connected to a water faucet or the like to dissolve disinfectant molded products and continuously obtain disinfectant water. It is suitable as a disinfecting water supply device when disinfecting containers, floors, etc. [Prior art] Molded disinfectant For example, a disinfectant whose main ingredients are inorganic bleaching powder, calcium hypochlorite, trichloroisocyanuric acid, sodium dichloroisocyanurate, potassium dichloroisocyanurate, etc. is molded into tablets or the like. The disinfectant molded products are used for disinfecting swimming pool water, sterilizing wastewater from sewage treatment plants, industrial wastewater treatment plants, etc., and sterilizing household septic tanks. A mold dissolver or device is employed. On the other hand, in facilities that handle food, such as food factories, cafeterias, school lunch centers, schools, factories, buildings, etc., disinfection of tableware, utensils, equipment, containers, floors, etc.
Conventionally, an aqueous solution of sodium hypochlorite has been used. For example, to disinfect tableware, etc., the tableware, etc. is immersed in a sterilization tank filled with disinfectant water that has been prepared by weighing water and sodium hypochlorite and mixing them to a predetermined disinfectant concentration (effective chlorine concentration). and do it. [Problems to be Solved by the Invention] When a large amount of tableware, etc. is processed by the above method, the disinfectant water initially put in the disinfectant water gradually decreases, and the disinfectant concentration also decreases. Therefore, it is necessary to additionally supply water and disinfectant, but it is generally extremely difficult to determine the amount, weigh them, etc. In addition, the sodium hypochlorite aqueous solution has an extremely fast decomposition rate, and the effective chlorine concentration decreases rapidly during storage. Normally, it is extremely difficult to measure the effective chlorine concentration of the sodium hypochlorite aqueous solution being stored in cafeterias, etc., and even if it is possible to measure it, the amount of sodium hypochlorite used is based on that value. Adjusting is an extremely troublesome task. On the other hand, conventionally used disinfectant molded material dissolvers or devices generally process a large amount of water compared to the amount of water used as disinfectant water for tableware, etc.; It is unsuitable for use as a SUMMARY OF THE INVENTION An object of the present invention is to provide a disinfectant molded dissolving device that is capable of continuously producing disinfectant water, and in particular can be connected to a water tap or the like to produce disinfectant water of a desired concentration. [Means for Solving the Problems] The present invention has a filling mechanism and a water injection mechanism that align and fill the disinfectant molded products in a vertical line, and the filling mechanism fills the disinfectant molded products aligned and filled at the lower end thereof. This disinfectant molded dissolving device has a structure in which the surface of the disinfectant molded product is exposed, and a filling mechanism and a water injection mechanism are arranged so as to spray water onto the exposed surface of the disinfectant molded product. In the present invention, the disinfectant molded product to be dissolved is a solid disinfectant shaped into a disc, cylinder, donut, square, prism, etc., such as inorganic bleaching powder, calcium hypochlorite, trichloroisocyanurate, etc. Acids, sodium dichloroisocyanurate, potassium dichloroisocyanurate, etc. alone or in mixtures with excipients. As a disinfectant molded product, the solid disinfectant has a disk shape with an outer diameter of 20 to 100 mm,
Cylindrical and donut-shaped molded products are commercially available.
Any of them can be targeted. The present invention will be described in detail based on the accompanying drawings showing one embodiment of the present invention. In FIG. 1, the filling mechanism consists of a cylinder 1 having a bottom plate 2, a removable top cover 3 and several slits 4 at the lower end. On the other hand, the water injection mechanism
Consisting of an inner tube 5, an outer tube 6, an upper lid 7 and a lower lid 8,
The lower part of the inner tube 5 has a large number of small holes 9, the upper cover 7 has an attachment port 10 and a water supply pipe connection port 11 for the cylinder 1, and the lower cover 8 has a water outlet 12. Cylinder 1 is mounting port 10
The height is adjusted and fixed by the adjustment mechanism 13. The cylinder 1 only needs to be able to fill the disinfectant molded product A in a vertical line, has an inner diameter 2 to 30 mm larger than the maximum outer diameter of the disinfectant molded product A that is normally used, and has a height that is equal to the disinfectant molded product that is filled at one time. Select arbitrarily depending on the number of objects A. When the shape of the disinfectant molded product A is polygonal, the cylinder 1 can be replaced with a rectangular cylinder according to the shape. If the disinfectant molded product A is doughnut-shaped, a stopper 2' may be provided at the lower end of a round bar or tube 1' having an outer diameter 3 to 30 mm smaller than its inner diameter, as shown in Figure 2. It can be done. The slit 4 is one aspect of the structure that exposes the surface of the disinfectant molded product A filled at the lower end of the cylinder 1. Therefore, instead of the slit 2, a large number of small holes may be used, or a net-like structure may be used. When the filling mechanism shown in FIG. 2 is employed, since the surface of the disinfectant molded product A is exposed, there is no need to provide a special exposing structure. The inner tube 5 has an inner diameter that allows the cylinder 1 to be inserted without coming into contact with the inner tube, and has water B in the space between it and the outer tube 6.
A large number of small holes 9 are provided on the entire surface of the lower half portion in order to inject water B inside the inner tube 5 by press-fitting the inner tube 5 . The outer tube 6 does not necessarily have to be a circular tube as long as it can create a space between it and the inner tube 5 in which the water B can be press-fitted. The upper lid 7 and the lower lid 8 only need to seal the space between the inner tube 5 and the outer tube 6, prevent the water jetted from the small holes 9 from scattering, and collect and discharge the water.
Instead of the flat plate shown in FIG. 1, it may be shaped like a cone or a cap. In particular, the lower lid 8 is preferably shaped like a cone or a cap to prevent scale from accumulating due to the disinfectant. The mounting opening 10 of the cylinder 1 has a diameter that allows the cylinder 1 to slide in order to arbitrarily adjust the mounting height of the cylinder 1 using an adjustment mechanism 13. Water supply pipe connection port 11
It is sufficient that water can be press-fitted between the inner tube 5 and the outer tube 6, and it may be provided not only in the upper lid 7 but also in the outer tube 6. The water outlet 12 may be provided inside the inner tube 5 so that the water jetted from the small hole 9, that is, the disinfectant water C, can be discharged without being retained inside. There are no particular restrictions on the adjustment mechanism 13 as long as it has a structure that can adjust the relationship between the exposed part of the disinfectant molded product represented by the slit 4 of the cylinder 1 and the height position of the small hole 9, that is, the water spout position. do not have. For example, as shown in FIG. 3a, the cylinder 1 is equipped with a collar 13', and the upper lid 7 is
A mechanism for adjusting by inserting a spacer 14 such as a gasket between them, or a mechanism for adjusting by using an adjusting ring 13'' and an adjusting screw 15 as shown in FIG. 3b can be adopted. In FIG. Although an embodiment example is shown in which the mechanism and the water injection mechanism are integrated, it is also possible that the filling mechanism and the water injection mechanism are independent, and the arrangement relationship between them can be arbitrarily adjusted by an adjustment mechanism. In this case, it is preferable to provide a spray water prevention mechanism corresponding to the upper lid 7 in FIG. 1 and a water collection mechanism corresponding to the lower lid 7. , anti-corrosion metals, glass, ceramics, synthetic resins, etc. can be used as long as they are not corroded by disinfectants and their aqueous solutions, preferably polyvinyl chloride, polyethylene, which are easy to process and low in price.
Synthetic resins such as polypropylene, nylon, and polyethylene terephthalate are used. [Operation] The operation of the present invention will be explained with reference to the attached FIG. 1. The water supply pipe connection port 11 of the disinfectant molded product dissolver shown in FIG. 1 is connected and fixed to a water supply pipe such as a water supply faucet,
Disinfectant molded articles A are arranged and filled in a vertical line in a cylinder 1. The surface of the lower portion of the disinfectant molded product A filled in the cylinder 1 is exposed through the slit 4.
When water supply is started, the water B press-fitted into the space between the inner tube 5 and the outer tube 6 is ejected through the small hole 9, and a part of it is sprayed onto the exposed surface of the disinfectant molded product A through the slit 4. Disinfectant molding A dissolves from its surface. When the disinfectant molded product at the bottom tier is dissolved, new disinfectant molded products sequentially fall from above and are replenished into the slit 4 portion. Therefore, depending on the amount of water sprayed, more precisely, the amount of water sprayed onto the exposed surface of the disinfectant molded product A, the disinfectant molded product is dissolved, and the disinfectant water C of a constant concentration is continuously applied over a long period of time. Manufactured in The concentration of the disinfectant water C obtained depends on the amount of water sprayed onto the exposed surface of the disinfectant molding A. Therefore, the concentration of disinfectant water C can be arbitrarily adjusted by adjusting either the amount of water to be jetted B, the relationship between the exposed position of disinfectant molded product A and the jetting position of the jetted water, or both. The operation of the present invention has been explained based on the attached FIG. may not be an integral structure as shown in the attached FIG. 1, but may be independent from each other. [Example] Attached No. 1 shows one embodiment of the present invention.
