Description

Apparatus for cleaning interior of water tank

The present invention relates to a cleaning device for cleaning the interior of the water tank of the village water supply facilities, and more specifically, to deposit the sediment accumulated in the bottom of the water tank by spraying the washing water toward the bottom or bottom and the inner wall of the water tank during cleaning The present invention relates to a water tank cleaning device that allows to clean the scales adhered to the inner wall.

The present invention also relates to a water tank of a village water supply facility in which such a cleaning device is installed, and to clean the water tank of the village water supply facility, which is prescribed by law to be carried out twice a year, more than a predetermined number of times, for example, a manager of a village water supply facility. It is about a water tank that can be carried out at any time whenever it feels necessary.

In general, the water tank of the village water supply facility includes an inlet pipe for supplying and replenishing an appropriate amount of water in the water tank according to the internal water level, a water supply pipe for distributing and supplying the water in the water tank to each user, and in the water tank. Overflow when excess water is supplied when the water is supplied excessively, and a drain pipe used when the inside of the water tank needs to be emptied, such as when cleaning the water tank, is installed. It is.

However, because the water tank of the village water supply facility is filled with valley water or groundwater, there is only a difference in degree depending on the water quality. As time goes on, the bottom of the water tank accumulates in the form of sand, earth or sand, and slips. In the distance, the scale clings to the inner wall.

On the other hand, since most of these precipitates and scales contain organic matter, when the internal temperature of the water tank becomes a good temperature for bacteria to act, it is prone to decay, and the substances produced in the process of decay are dissolved in water. Can be watered together. This is one of the causes of waterborne diseases that commonly occur in summer. Also, although such deposits and scales are not as harmful as we think, they will be considered dirty if they contain sediments or the like.

For these reasons, water tanks in village waterworks are required to be cleaned twice a year. However, cleaning twice a year in accordance with the law does not guarantee that we can use it safely.

In addition, the current water tank cleaning method has the following problems.

For example, the current cleaning method is a method in which a person directly enters a water tank and cleans it with water while removing the sediment on the floor and the scale of the inner wall with a cleaning tool such as a brush. Workers sometimes suffocated by toxic gases, leading to death. This toxic gas is derived from chlorine disinfectants used to sterilize and disinfect water.

On the other hand, when cleaning the water tank, it is necessary to notify the user of the scheduled cleaning time so that the required amount of water can be received before leaving the water tank completely empty. Depending on the cleaning agent's circumstances, the scheduled cleaning time is delayed. It wasn't uncomfortable because it was a common case of losing.

Also, in some cases, it may be better to clean the water tank once more even after obeying the two cleaning duties required by law.However, cleaning performed at this time is optional and not required. Usually it was omitted.

For this reason, even though there are some problems in the water quality management of village waterworks, the situation is not proposed at all due to economic circumstances and lack of regulations.

The present invention has been proposed to solve the conventional problems related to the cleaning of the water tank, it is possible to clean the water tank at any time in a short time, it is not necessary to use the expertise or technology in adjusting the spraying direction and the spraying position of the washing water. It is an object of the present invention to provide a water tank cleaning device that is convenient and free from corrosion and breakdown, and a water tank equipped with such a water tank cleaning device.

Here, the manifold and the wash water distribution pipe may be provided in a separable type that can be separated from each other, but may be provided as a single body by welding.

In addition, as described in claim 3, by further installing a chemical storage room on one side of the storage room and connecting the chemical delivery line there, so that the chemical in the chemical storage room can be transferred to the place where the injection nozzle is located along the chemical transport line without force. It is desirable to. Such a chemical storage room and a chemical transfer line usually perform a function as a chlorine chemical automatic injection means, and when cleaning, they function as a sterilizer to disinfect the inside of the water tank with chlorine chemical. And these two functions can be achieved, for example, by dividing the opening degree of the on-off valve installed in the chemical delivery line into normal and cleaning, opening a little more than usual and a little less when cleaning.

Hereinafter, the features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

Prior to this, terms or words used in the present specification and claims are described based on the principle that the inventor can appropriately define the concept of terms in order to explain the invention in his best way. It must be interpreted as meanings and concepts corresponding to ideas.

Therefore, this invention is not limited to the Example mentioned later.

First, with reference to the accompanying drawings, Figure 1 is a perspective view showing the appearance of the cleaning tool of the water tank cleaning apparatus according to an embodiment of the present invention, Figure 6 is a plan view and a perspective view of the direction control member used for such a cleaning tool .

As shown in the figure, the cleaning tool 300 according to the present embodiment includes a cylindrical manifold 360 and washing water distribution pipes 361, 363, 365, which are piped to the water outlet side (lower portion in the drawing) of the manifold 360, respectively. ), A handle 380 welded to a short pipe protruding from the upper surface of the manifold, and four holes 391, 393, 395, 397 through which the washing water distribution pipe and the chemical extraction pipe can be passed through the spherical surface 399. When the cleaning tool is installed, the circumferential portion of the spherical surface is supported by the circumference adjustment member 390 around the bottom of the enclosure, and when the other pipes are directly fixed to the washing water distribution pipe or connected to the washing water distribution pipe, the ends of the other pipes. It consists of injection nozzles 311, 313, and 315 fixed to it.

In the case of installing the cleaning tool, the spray nozzle 313 facing the bottom of the water tank is directly fixed to the end of the washing water distribution pipe 363 extending downward through the direction adjusting member, wherein the washing water is clamped. When the flanges of the pipe and the spray nozzle were fixed to each other, the clamp was released later so that the wash water distribution pipe and the spray nozzle could be separated from each other.

In the case of the spray nozzles 311 and 315 provided toward the inner wall of the water tank, the end portions of the washing water distribution pipes 361 and 365 are formed by corrugated pipes 321 and 325 whose ends are bent at about 90 ° with respect to each other. Fixed to the other end, and then fixed to the other end of the corrugated pipe.

Meanwhile, loops are formed at both ends of the corrugated pipes 321 and 325, respectively, so that the turn buckles 341 and 345 can be filled between the loops. According to the configuration, according to the length of the turn buckle to be used, Since the spray nozzles face the inner wall or face down slightly toward the bottom of the water tank, the spraying direction of the washing water may change slightly.

Therefore, when the wash water flows into the washing water inlet pipe 230 connected to the short pipe on the upper side of the manifold, the washing water is sprayed toward the bottom and the inner wall of the water tank through the washing water distribution pipe connected to the manifold 360.

In cleaning the inside of the water tank, the inside of the water tank is usually cleaned, but sometimes only the bottom of the water tank or only the inner wall may be cleaned. Therefore, in this embodiment, the opening / closing valve 371 for each washing water distribution pipe can be achieved. , 373, 375). Assuming that the supply pressure of the wash water is constant, when one of the on / off valves is locked, the wash water flowing to the open / close valve is sprayed through the spray nozzle at a higher water pressure, so that it can be cleaned more cleanly. have.

2 is a schematic view showing a state in which a water tank cleaning device including a cleaning device 300 having the above configuration is installed on an upper surface of the water tank.

As shown in the figure, four pipes are connected to the water tank 100, respectively.

Of the four pipes, the pipe connected to the upper left side of the water tank is an intake pipe 110, through which the water is introduced and stored into the reservoir 150 of the water tank. The overflow 120 is installed at the upper right side of the water tank so as to be slightly higher than the water inlet pipe 110, and by this overflow, a part of the water excessively supplied into the reservoir is discharged. In addition, the water supply pipe 130 and the drain pipe 140 are connected to the bottom of the reservoir. In addition, the three valves except the overflow valves 161, 163 and 165 are respectively provided.

On the other hand, the mounting hole 170 for the water tank cleaning apparatus of the present invention is drilled on the upper surface of the water tank. The mounting hole is preferably formed at the center of the upper surface of the water tank, but may be formed slightly biased to either side of the upper surface of the water tank depending on the site conditions.

Therefore, the configuration of the water tank is the same as the conventional one except that the installation hole 170 is further formed. In the case of this embodiment, the shape of the mounting hole is circular, but may be other shapes than circular. Further, with respect to the conventional water tank, an installation hole may be formed afterwards.

On the upper surface of the water tank in which the installation holes are formed, the enclosure 200 of the water tank cleaning device is mounted and fixed in such a manner as to cover the installation holes. There may be several ways to fix the enclosure, for example if a new water tank is being manufactured, install a bracket on the surface of the enclosure and cement the bracket to the top of the water tank, or pre- anchor bolt on the top of the water tank. It can be installed and tightened or welded to bracket and anchor bolts.

In the inner storage chamber 220 of the enclosure 200, the cleaning device 300 of the present invention is installed so that the lower end portion can be exposed to the water tank. In addition, one side of the storage chamber is installed in the chemical storage chamber 210, at a point slightly away from the chemical storage chamber, one end is connected to the other side of the washing water inlet pipe 230 connected to the inlet pipe. The on-off valve 231 is provided on the pipeline of the washing water inlet pipe. On the other hand, when one end of the washing water inlet pipe to the inlet pipe 161, the connection position should be to the front of the on-off valve 161 installed on the water pipe of the inlet pipe.

3 and 4 is an enlarged view and a state of use of the water tank cleaning device described above.

As shown in these figures, at the bottom of the storage chamber 220 of the enclosure 200, a position fixing tool 221 for aligning with the installation hole 170 of the upper surface of the water tank is formed. In the present embodiment, the position fixing tool is in the form of a short tube, but a simple hole may be used.

The installation of the cleaning tool is completed by a simple operation of opening the enclosure and pushing the lower part of the cleaning tool 300 of the present invention toward the position fixing tool on the bottom of the storage compartment.

That is, the bowl-shaped direction adjusting member 390 provided in the form of partitioning the upper and lower ends of the cleaning tool has a spherical diameter 399 rounded down than the diameter of the position fixing tool, thereby naturally The peripheral part is supported around the position lock.

When the cleaning device is installed, the connection between the washing water inlet pipe 230 connected to one side of the enclosure and the short pipe protruding from the top of the manifold 360 of the cleaning device is connected to the cleaning water connection pipe 400.

In addition, after inserting the drug distribution port 530 having three discharge ports at the end of the withdrawal pipe 510 connected to the chemical storage chamber on one side of the enclosure, for example, as shown in FIG. The chemical injection tube is guided to the vicinity of the injection nozzle and fixed to the eyelet 693 formed on one side of the injection nozzle as shown in FIGS. 5A and 5B.

By doing in this way, installation of a water tank cleaning apparatus is complete | finished completely.

When the water tank is cleaned, all of the opening and closing valves 161 and 163 installed in the water inlet pipe 110 and the water supply pipe 130 are locked, and the opening and closing valves 231 and 165 provided in the washing water inlet pipe 230 and the drain pipe 140 are Leave open In addition, the opening and closing valve 520 for opening and closing the outlet pipe 510 connected to the chemical storage chamber 210 is left open.

In this state, when the pump (not shown) is driven, the water flowing into the water inlet pipe 110 is turned toward the washing water inlet pipe 230 so that water is supplied to the cleaning device of the present invention.

The supplied water is appropriately dispersed in the three washing water distribution pipes 361, 363, 365 through the manifold 360, and the water tank through the spray nozzles 311, 313, 315 corresponding to the respective washing water distribution pipes. Sprayed towards the inside.

In this way, when the washing water is injected into the water tank, when the operator grasps the handle 380 of the cleaning device 300 and shakes around, the position of the injection nozzle in the water tank is changed to change the spraying direction of the washing water as shown in FIG. .

Depending on the number of injection nozzles, for example, if the number is two, by rotating the handle 380 in the horizontal direction by 180 ° can be cleaned by spraying the washing water throughout the inner wall of the water tank, if the number is three or four, respectively The entire inner wall can be cleaned by rotating it by 120 ° or 90 °.

5A and 5B are cross-sectional views schematically illustrating an internal configuration of a rotary jet nozzle which may be used in the cleaning tool of FIG. 1, FIG. 5A is a state before washing water is introduced, and 5B is a state in which washing water is introduced. It is shown.

As shown in the drawing, in the rotary jet nozzle used in the present embodiment, the second casing 620 is fixed to the clamp 660 at one side of the first casing 610 in which a cylindrical inner space is formed. A leak preventing seal 670 is sandwiched between the second casing and the second casing. On one side of the second casing, a conduit connected to the washing water distribution pipe or the corrugated plate is formed, and the washing water introduced through the conduit is transferred to the first casing as it is.

On the other hand, between the inner ends of the flange portion of the first casing and the second casing, which are fixed to each other by the clamp 660, a rod through hole is drilled in the center, and a plurality of water holes 651 are formed around the rod through hole. The perforated support plate 650 is fitted. The rod 630 is provided in the rod through hole of the support plate in such a manner that the lower end portion is exposed inside the first casing and the upper end portion is exposed inside the second casing.

At the upper end of the rod, a spring 640 is provided, one end of which is supported by the support plate 650 and the other end of which is supported by a stop ring 641 fixed to the end of the rod.

In addition, at the lower end of the rod, a porous plate 690 having a plurality of water outlets 691 is provided in the form of blocking the lower end opening of the first casing. The rotary injection means 680 which changes the discharge direction of wash water by the water extraction hole 681 is provided.

Further, below the rotary injection means, a plate-like member having the same size as that of the porous plate 690 but no holes at all or a relatively smaller hole size is provided.

Therefore, when the washing water is supplied to the inside of the first casing through the water hole 651 of the support plate, water pressure acts on the porous plate and the plate-shaped member installed at the lower end of the rod in the direction in which the spring at the top of the rod is compressed, that is, FIGS. The rod moves together.

Meanwhile, some of the washing water introduced into the rotary spray means 680 through the water outlet 691 of the porous plate is discharged through the water outlet 691 in an inclined form, but some are inclined with respect to the central axis of the rod. Flows into the hydraulically actuated groove 683. Thus, when the washing water flows into the hydraulically acting groove, the rotating spray means tends to be pushed out of the plate-like member toward the perforated plate, and the washing water is sprayed by this force or tendency and through the inclined outlet hole 691. The rotational injection means rotates at a constant speed in place by the reaction of time.

The rotational speed of the rotary spray means may be adjusted according to the water pressure of the washing water supplied and the number of the water outlets 691 and the inclination degree of the water outlets.

Here, reference numeral 661, 663, 665 is a fixing ring for preventing the separation of the component.

On the other hand, according to the self-cleaning device of the present invention, as shown in Figure 5b, since the chemicals are supplied in the form of drops falling within the spray water spraying range, there is an effect that the cleaning and disinfection of the inside of the water tank is performed together.
