Description

[Technical Field]

[0001] The present invention relates to a release drainage mechanism that prevents drainage pools and organic matter from adhering and remaining near the drain outlet in drainage devices such as drain boxes, floor drains, or drain pans, thereby suppressing the generation of bad odors. [Background technology]

[0002] The specifications of conventional drainage outlets, including drain manholes, consist of a grating cover at the top for water passage, a wire basket below that, a space at the bottom, and a drainage pipe connected to the bottom via a water sealing mechanism. However, in the past, the water sealing mechanism in a drainage manhole, for example, would discharge wastewater into the drain pipe when it reached a certain water level. Therefore, in the drainage manholes and other facilities in food factories, the drainage pool in the water sealing mechanism was prone to bacterial growth, odor generation, and the accumulation of dirt. For this reason, they were cleaned periodically, which required a lot of time and effort. Furthermore, the effective installation depth was large, which increased the installation depth, including the slope of the drainage main pipe, and resulted in increased installation costs. DISCLOSURE OF THE INVENTION Problem to be solved by the invention

[0003] The present invention provides a release drainage mechanism that eliminates the accumulation of wastewater in drainage equipment such as drainage manholes, floor drains, and drainage pans in food factories, thereby preventing the proliferation of bacteria, the generation of odors, and the adhesion of dirt, while advantageously enabling labor savings by rationally shortening the time required for periodic cleaning, and also reducing the effective installation depth of drainage manholes, etc., and shallowing the equipment depth including the slope of the drainage main pipe, thereby reducing equipment costs.

[0004] The technical features of our proposal to solve the above-mentioned problems are as follows (1) to (3). (1) A release drainage mechanism for a drainage device, characterized in that a grating cover (101) is placed on the top of the drainage device, a mesh basket (102) is provided below it, a release drainage mechanism (200) is connected to the bottom of the space below it, a drainage pipe (300) is connected to the release drainage mechanism (200), the release drainage mechanism (200) has a screw mechanism and a grip unit (202) at the detachable part at the top end, a cylindrical discharge pipe (203) is connected below the unit (202), and a release valve (205) with an attached counterweight (206) that opens and closes due to the weight of the introduced drainage water is provided at a drainage port (208) at the bottom of the cylindrical discharge pipe (203). (2) The release drain mechanism of the drain device according to (1) above, characterized in that the drain device is a drain box, a floor drain, or a drain pan. (3) The release drainage mechanism of the drainage device according to (1) above, characterized in that the inner surface of the release drainage mechanism (200) is coated with a paint (207) that prevents adhesion of organic contaminants.

[0005] In the drainage device of the present invention, the release drainage mechanism reduces the effective installation depth of the drainage manhole by using the cylindrical discharge pipe with the release valve of the above-mentioned characteristics, and reduces the equipment depth including the slope of the main drainage pipe, thereby reducing equipment costs.It also eliminates wastewater accumulation in the drainage manhole in food factories, preventing the growth of bacteria, the generation of odors, and the adhesion of dirt, and makes it possible to shorten the time required for regular cleaning in a rational manner, thereby advantageously saving labor.

[Figure 5-2] FIG. 10 is a simplified perspective view showing a third embodiment in which the release drainage mechanism is applied to a drain pan 600 as a drainage device. MODE FOR CARRYING OUT THE INVENTION

[0007] A mode for carrying out the present invention will be described with reference to the embodiment shown in Figures 1 to 5. In this embodiment, a release drainage mechanism is applied to a drainage basin as a drainage device. Example 1

[0008] The first embodiment is an example in which a release drainage mechanism is applied to a drainage basin 100 as a drainage device. 1 to 4, the drainage bin 100 comprises a grating cover 101, a mesh basket 102 that collects impurities in the drainage water with its mesh, a bin body 103 having a space below it, and a release drainage mechanism 200. The grating cover 101 and the mesh basket 102 are detachably placed on top.

[0009] The release drainage mechanism 200 connects a discharge pipe 300 to the bottom opening of the manhole body 103, and threads a cylindrical discharge pipe 204 into the discharge pipe 300. A threaded unit 202 consisting of a thread and a gripping rod for rotation is provided at the upper threaded portion of this cylindrical discharge pipe 204, and a release valve 205 that opens when the weight of drainage water introduced into the pipe is provided at the diagonally cut drainage outlet 208 at the bottom of the cylindrical discharge pipe 204. The release valve 205 is provided with a counterweight 206 for opening due to the weight of the wastewater introduced into the cylindrical discharge pipe 204 . The lower end of the discharge pipe 300 is connected to a drainage collecting pipe 400 .

[0010] The weight relationship between the weight Cw of the counterweight 206 and the weight Bw of the release valve 205 is such that Cw > Bw when the release valve 205 is closed, and Cw < Bw + α when the release valve 205 is open. That is, when there is no drainage in the cylindrical discharge pipe 204, the release valve 205 is always in the closed state. When a small amount of drainage α flows in, the release valve 205 is opened to discharge the residual water, suppressing the remaining drainage.

[0011] This function and effect prevent the malodor from the residual drainage in the cylindrical discharge pipe 204, the intrusion of malodor from the drainage discharge pipe 300 and the drainage discharge collecting pipe 400, and the discharge into the food factory. Also, the inner wall of the cylindrical discharge pipe 204 and the upper surface of the release valve 205 are coated with an anti-adhesion paint 207 for organic contaminants. Here, it also prevents the generation of malodor due to the adhesion of organic contaminants, and prevents the fine contaminants contained in the drainage from adhering to the release valve 205 to maintain the airtight state during closing and prevent the leakage of malodor.

[0012] The anti-adhesion paint 207 is, for example, the paint applied to the pit device introduced in the patent registration No. 7324391 of the applicant of the present application. The feature is "100 parts by weight of alkali silicate, a total of 5 to 20 parts by weight of calcium silicate and / or zinc phosphate as a curing agent are added, and as an inorganic filler, colemanite (2CaO, 3B2O3, 5H2O) and / or ulexite (Na2O, 2CaO, 5B2O3, 16H2O) are mainly used. A water-based inorganic paint containing a mixture of 20 to 80 parts by weight of fine scaly natural glass with an average particle size of 30 μm and a thickness of 1.0 μm or less having a B2O3 component elution effect is applied to form a coated portion." is recommended.

Example 2

[0013] Example 2 is shown in the simplified perspective view of FIG. 5-1. Example 2 shown in FIG. 5-1 is an example in which the release drainage mechanism 200 having the same configuration as the release drainage mechanism 200 shown in Example 1 is applied to the floor drain 500 as a drainage device, and the detailed description thereof is omitted.

Example 3

[0014] The simplified perspective view of FIG. 5-2 shows Example 3. The third embodiment shown in FIG. 5-2 is an example in which a release drain mechanism 200 having the same configuration as the release drain mechanism 200 shown in the first embodiment is applied to a drain pan 600 as a drain device, and a detailed description thereof will be omitted.

[0015] In this way, the release drainage mechanism of each of Examples 1 to 3 minimizes the amount of drainage in the drainage manhole in a food factory to a water-sealed minimum, thereby preventing the proliferation of bacteria, odor generation, and dirt adhesion, and advantageously enables labor savings by rationally shortening the time required for periodic cleaning.In addition, the effective installation depth is small, and the equipment depth, including the drainage main pipe gradient, is shallow, thereby reducing equipment costs.Industrial Applicability

[0016] As described above, the present invention exhibits excellent effects and therefore will make a great contribution to the food processing industry and the drainage pit construction industry, which utilize the drainage pit. [Explanation of symbols]
