Description

The present invention relates to a cleaning device for cleaning the inner surface of a tank such as a storage tank, and cleaning parts that constitute the cleaning device.

At sites where food and medicine are handled, tanks are used for a variety of purposes, including storage, compounding, and reactions. In order to automate this tank cleaning, cleaning devices called shower balls and spray balls have been developed.

Considering that such a cleaning device is permanently installed inside the tank, it has a small configuration compared to the size of the tank. Therefore, considering the distance to the inner wall of the tank, the tank is cleaned by spraying cleaning liquid from the cleaning device at a pressure higher than a certain level and letting it flow against the wall surface. In this regard, in order to eliminate uneven cleaning, a cleaning device has been developed in which a plurality of injection holes are provided at different angles and the injection holes are configured to be rotatable.

Hereinafter, a cleaning component 1 and a cleaning device X according to an embodiment of the present invention will be described using the drawings. The explanation will be detailed in the order of the configuration of the embodiment, modifications, and implementation methods.
In addition, each embodiment shown below is an example of this invention, and this invention is not limited to each following embodiment.

≪First embodiment≫
The cleaning device X according to the present embodiment includes a cleaning component 1, a liquid feeding component 2, and a holding component 3, as shown in FIG. The inner wall surface of the tank T is cleaned by spraying a cleaning liquid (water, co-cleaning chemicals, etc.) inside the tank T having the piping T1.

In the drawings used to describe the present embodiment, FIG. 1 first shows a plan view of a cleaning component 1 showing the injection holes that spray cleaning liquid and/or the axis thereof. In FIG. 2, FIG. 2(a) and FIG. 2(c) are views of the cleaning component 1 seen from two directions on the equatorial plane, and FIG. 2(b) is seen from the front in FIG. 2(a). Enlarged view of injection hole group, FIG. 2(d) shows an enlarged view of the injection hole group seen from the front in FIG. 2(c). 3(a), 3(b), 3(c), and 3(d) are cross-sectional views on planes A, B, C, and D shown in FIG. 1, and on or near each cross-section, respectively. The axis of the injection hole provided in the 4(a) is a diagram showing the entire cleaning device X, and FIG. 4(b) is a sectional view of the cleaning device X. FIG. 5 is a schematic diagram showing the usage state of the cleaning device X, and also shows the direction in which the cleaning liquid is sprayed.

As shown in FIG. 1, the cleaning component 1 is a member having a shell portion 11 capable of storing liquid therein, and an insertion portion 12 into which the liquid-feeding component 2 is inserted or passed through in a liquid-tight manner. The cleaning liquid sent from the component 2 into the shell part 11 and filled therein is injected toward the outside. Further, the cleaning component 1 is rotatably connected to the liquid feeding component 2. The rotation axis at this time is an axis passing through the center of the cleaning component 1 in plan view as shown in FIG. 1, and this is defined as the polar axis P.

The shell portion 11 is a shell-shaped member that determines the general shape of the cleaning component 1, and is filled with the cleaning liquid sent inside. The shape of the shell portion 11 is assumed to be spherical or ellipsoidal, but as shown in FIGS. 2 and 3, it may also have a shape close to a cylindrical shape with the top and bottom flattened to be perpendicular to the polar axis P. good. However, regardless of the shape of the shell portion 11, it is preferable that the thickness of the shell be constant at all locations.

By making the shell part 11 into a crushed shape, the height of the entire cleaning device X with respect to the polar axis P can be suppressed as shown in FIG. It is possible to reduce the possibility that the cleaning device X will come into contact with the chemicals when storing the chemicals inside. Further, by making the gap between the cleaning component 1 and other components as small as possible, it becomes difficult for chemicals to enter the gap in the cleaning device X.

The shell portion 11 has an injection hole that injects cleaning liquid to the outside. The injection holes are small holes or slits that penetrate from the inside of the shell portion 11 to the outside, and are classified according to the position and direction in which they are drilled. In this embodiment, the shell portion 11 has a plurality of injection hole groups provided at approximately equal intervals, a first injection hole group 111 and a second injection hole group in which five small holes are bored in a row. 112, the third injection hole group 113, the fourth injection hole group 114, the first auxiliary injection hole 115 which is a small hole drilled independently, the second auxiliary injection hole 116 which is a slit, and the cleaning component 1 are rotated. It has a rotating injection hole 117 that is moved.

The first injection hole group 111, the second injection hole group 112, the third injection hole group 113, and the fourth injection hole group 114 are groups of injection holes each having five small holes drilled in a row. By having different perforation arrangements, cleaning liquid can be sprayed from more angles. The perforation arrangement of each injection hole group is determined by the longitudinal direction shown in FIG. 1 and the latitudinal direction shown in FIG. 3. In addition, in each of the injection holes, the axes indicating the injection direction of the cleaning liquid are the first injection axis Q1, the second injection axis Q2, the third injection axis Q3, and the fourth injection axis in each of FIGS. 1, 2, and 3. It is expressed as Q4.

As shown in FIG. 1, the longitude direction that determines the drilling position of each injection hole is the direction of a line connecting the upper pole UP to the lower pole LP via the equator E on the outer surface of the shell part 11, It is similar to the concept of general longitude (longitude used to indicate a point on the earth).
Similarly, if the shell part 11 is spherical, the latitudinal direction is an angle that opens from the direction corresponding to the equator E toward the poles based on the center point of the sphere, and This is similar to the concept of latitude (used to indicate latitude). However, as shown in FIG. 3, this is not the case when the shell portion 11 has a shape that is collapsed from a spherical shape.

When the shell part 11 has a crushed shape, the center in the latitudinal direction has a predetermined radius centered on a point on the polar axis P and on the equatorial plane, and further on the circumference of 1 on the equatorial plane. An arbitrary point provided is used as the pseudo center G.
Here, the equatorial part E according to the present embodiment is defined by the polar axis P, and is the intermediate height between the upper pole UP and the lower pole LP of the cleaning component 1, or when going from the upper pole UP to the lower pole LP. This refers to the part where the shell portion 11 is the most swollen. Further, an arbitrary straight line that is on a plane defined by the equator E and passes through the polar axis P is defined as an equatorial plane axis F.

The circumference (radius) that determines the pseudo center G is determined so as to overlap the insertion portion 12 when the cleaning component 1 is viewed from above, or is determined at the center point that determines the curved surface of the shell portion 11. Good too. The pseudo center G determined above becomes a reference point in the latitudinal direction for determining the drilling position of each injection hole, and the drilling arrangement of each injection hole is determined in this "pseudo" latitudinal direction.

With such a configuration, even if the cleaning component 1 is in a crushed shape as shown in FIGS. 3(a), 3(b), 3(c), and 3(d), the shell portion 11 On the other hand, the length of each injection hole can be made substantially constant, and it is less likely to be restricted by the tools used for drilling or from the viewpoint of strength.

The perforation arrangement of the first injection hole group 111 is determined based on the above in the latitude direction shown in FIG. 3(d) and the longitude direction shown in FIG. 1. First, among the five injection holes to be drilled, the latitude direction of the middle injection hole is set to the first elevation angle R1, and the longitude direction is set to an arbitrary equatorial plane axis F, for example, a point included in the plane D shown in FIG. Define direction. Based on this, the drilling positions are shifted by 2 degrees in the latitude direction and 6 degrees in the longitude direction so that the five injection holes are aligned substantially in a straight line. The first injection hole group 111 drilled in such an arrangement has an appearance shown in FIGS. 2(a) and 2(b). The same applies to the third injection hole group 113 shown in FIGS. 2(c) and 2(d).

With such a perforation arrangement, although it depends on the cross section of each injection hole and the size of the shell portion 11, the injection holes can be drilled with a small angle change and the cleaning liquid can be injected without causing the injection holes to interfere with each other.
For example, as shown in FIGS. 2(b) and 2(d), when the latitude change between the injection holes is small and the injection holes are provided on the same meridian, the injection holes interfere with each other in the latitudinal direction. Moreover, if the injection holes are too close together, the walls between the injection holes will become thin and the strength will be impaired. Therefore, by arranging the plurality of injection holes in a substantially straight line, interference between the injection holes can be avoided, and the injection holes can be provided while suppressing angular changes.

As a reference example, in the first injection hole group 111 shown in FIGS. 2(a) and 2(b), the change in the latitude direction between adjacent injection holes is 2 degrees, and the change in the longitude direction is 6 degrees. The cross section of each injection hole is circular with a diameter of 2 mm, and the radius of the equatorial portion E is 35 mm. At this time, as shown in FIG. 2(b), the cross sections between adjacent injection holes in the latitudinal direction overlap by more than half. To avoid this, changes in the longitude direction are added.

Similarly to the above, the second injection hole group 112, the third injection hole group 113, and the fourth injection hole group 114 have the latitude direction determined by the second elevation angle R2, the third elevation angle R3, and the fourth elevation angle R4, respectively, and the longitude direction The directions are also determined to be 90 degrees, 180 degrees, and 270 degrees clockwise from the longitude direction of the first injection hole group 111, respectively.

As a reference example, the first elevation angle R1 is 11 degrees in FIG. 3(d), the second elevation angle R2 is 21 degrees in FIG. 3(c), and the third elevation angle R3 is 33 degrees in FIG. 3(d). The four elevation angles R4 are determined to be 53 degrees in FIG. 3(c). In addition, the deviation in the latitudinal direction of each injection hole group is 2 degrees for the first injection hole group 111 and the second injection hole group 112, 3 degrees for the third injection hole group 113, and 5 degrees for the fourth injection hole group 114. The change in longitudinal direction is 6 degrees for each injection hole group.
With this configuration, the cleaning liquid can be sprayed at elevation angles in 20 directions without overlap, and the number of locations where the cleaning liquid directly hits the inner wall surface of the tank T can be easily increased.

It is preferable that changes in the latitude and longitude directions that determine the perforation arrangement of the injection hole group are set to values appropriate to the shape of the shell portion 11. For example, when the shell part 11 is nearly spherical, the changes in the angle of the injection hole group in the latitudinal direction are all determined by a constant value, and the changes in the longitudinal direction are determined as the drilling position changes from low latitude to high latitude (from the equator side to the pole side). It is determined by increasing the angle as the angle increases. With such a configuration, the injection holes can be made to appear at substantially constant intervals and directions when viewed from the outside of the shell, and the design of the cleaning component 1 is improved.

In addition to the above, as shown in Figures 1, 2, and 3, the perforation arrangement of the injection hole group is such that changes in the longitude direction are all fixed, and changes in the latitude direction widen at higher latitudes. It is preferable to have a configuration defined by Generally, it is assumed that the cleaning device X is installed above the inside of the tank T (see FIG. 5). At this time, the ceiling of the tank T is close to the cleaning device X, and the wall surface to be erected is far from the cleaning device By setting the angle of the injection hole, you can apply cleaning liquid evenly and clean.

The latitudinal direction of the first auxiliary injection hole 115 is determined by an auxiliary elevation angle R5 that is larger than each elevation angle of the first injection hole group 111, the second injection hole group 112, the third injection hole group 113, and the fourth injection hole group 114. It is a small hole that penetrates from the inside to the outside. As a reference value, FIG. 3(b) shows an example in which the auxiliary elevation angle R5 is 72 degrees. In particular, it is preferable that the auxiliary elevation angle R5 is the maximum angle at which the cleaning liquid does not hit the holding part 3 when the cleaning device X is assembled as shown in FIG. Such a configuration prevents splashes of cleaning liquid and washed away chemicals from entering the gap between the holding part 3 and the cleaning part 1.
It is preferable that two or more first auxiliary injection holes 115 are provided point-symmetrically with respect to the polar axis P, or three or more first auxiliary injection holes 115 are provided rotationally symmetrically with respect to the polar axis P in order to give symmetry to the reaction of injecting the cleaning liquid.

The second auxiliary injection hole 116 is a long hole or slit whose latitudinal direction is set to an auxiliary depression angle R6 and whose longitudinal direction is in the meridian direction. The auxiliary depression angle R6 is a guideline indicating the angle of the center portion of the second auxiliary injection hole 116 in the latitudinal direction. With this configuration, the reaction when the cleaning liquid is injected from the first injection hole group 111, the second injection hole group 112, the third injection hole group 113, the fourth injection hole group 114, and the first auxiliary injection hole 115 is reduced. , prevents the cleaning component 1 from being pushed down in the direction of the lower pole LP.
It is preferable that two or more second auxiliary injection holes 116 are provided point-symmetrically with respect to the polar axis P, or three or more second auxiliary injection holes 116 are provided rotationally symmetrically with respect to the polar axis P in order to give symmetry to the reaction of injecting the cleaning liquid.

The rotating injection hole 117 is an injection hole bored on the equatorial plane (positioned as a sub-injection hole compared to the cleaning injection hole), and the equatorial plane axis F ( In FIG. 1, it is provided obliquely by an angle of deviation S1 from the axis included in the plane A (in FIG. 1). In other words, the axis indicating the direction of injection of the cleaning liquid in the rotational injection hole 117 is provided at a twisted position with respect to the polar axis P. With such a configuration, the cleaning component 1 can be rotated around the polar axis P using the reaction of spraying the cleaning liquid. FIG. 1 shows a configuration in which the declination angle S1 is 25 degrees as a reference value.
It is preferable that two or more rotating injection holes 117 are provided point-symmetrically with respect to the polar axis P, or three or more rotationally symmetrically provided, so that the reaction of spraying the cleaning liquid is symmetrical.

The insertion portion 12 is an opening for inserting or inserting the liquid feeding component 2 into the cleaning component 1 for connection, and has a circular cross section with an axis concentric with the polar axis P, as shown in FIG. Thereby, the cleaning component 1 is connected to the liquid feeding component 2 so as to be rotatable around the polar axis P.

As shown in FIG. 4, the liquid sending component 2 is a member that is inserted into the insertion portion 12 and connected to the cleaning component 1 to send cleaning liquid to the cleaning component 1, and has an inlet 21 and a flow path 22 inside. and has. The outer shape of the liquid sending component 2 is a cylinder that is concentric with the polar axis P when combined with the cleaning component 1, and has a flange that supports the lower pole LP side of the cleaning component 1.

The inlet 21 is a cylindrical member that connects the liquid sending component 2 and the pipe T1, and introduces the cleaning liquid sent into the tank T through the pipe T1 into the cleaning device X. Furthermore, a configuration in which spiral irregularities (threads) are provided on the wall surface for connection with the pipe T1 is preferable. At this time, it is preferable that the rotational direction in which the screw closes is the same as the rotational direction in which the cleaning component 1 is rotated by spraying the cleaning liquid. Such a configuration prevents the cleaning device X from coming off the pipe T1 even if force is applied to the liquid sending component 2 to rotate around the polar axis P due to friction with the cleaning component 1.
In addition, the inner wall of the introduction port 21 may be provided with a taper that narrows toward the direction in which the cleaning liquid flows.

The flow path 22 is a portion that allows the cleaning liquid flowing from the inlet 21 to flow in the direction of the polar axis P, then disperses the cleaning liquid in multiple directions corresponding to the equatorial plane axis F, and guides the cleaning liquid into the inside of the shell portion 11. It is. Further, the opening through which the cleaning liquid exits toward the inside of the shell portion 11 may be provided with a taper that widens outward. This configuration prevents the pressure caused by the flow of the cleaning liquid from concentrating near the equator E.

As shown in FIG. 4, the holding component 3 is an annular member that prevents the cleaning component 1 from coming off from the upper pole UP side when the cleaning component 1 and the liquid feeding component 2 are connected. The ring is connected to the liquid-feeding component 2 in such a manner that the liquid-feeding component 2 passes through the inside of the ring. However, in order to allow the cleaning component 1 to rotate, the holding component 3 and the cleaning component 1 are preferably constructed so that they do not come into contact with each other, and the holding component 3 is preferably stopped at a step provided on the liquid feeding component 2, for example.

It is preferable that the cleaning component 1, the liquid feeding component 2, and the holding component 3 are made of resin such as PTFE. With this configuration, various chemicals can be used as the cleaning liquid, and co-washing can be performed.
Moreover, the material of each component may be PTFE containing a filler, such as carbon-containing PTFE. Thereby, static electricity generated when spraying the cleaning liquid is not accumulated, and ignition within the tank T due to the static electricity can be prevented.

The cleaning device X may have the following configuration. However, the configuration shown below is just an example, and its presence or absence is determined independently unless there is a specific designation of dependency.

≪Example of change≫
Changes in the latitude and longitude directions that determine the perforation arrangement of the injection hole group may be determined at a constant angle in each of the latitude and longitude directions. With such a configuration, the drilling position of the injection hole can be easily determined during manufacturing.

As shown in FIG. 1, the first auxiliary injection hole 115 is provided obliquely by a sub-deflection angle S2 from the equatorial plane axis F (the axis included in the plane B in FIG. 1) passing through the opening on the outer surface side of the shell portion 11. It will be done. With such a configuration, together with the rotating injection hole 117, the cleaning component 1 can be rotated using the reaction of spraying the cleaning liquid. Note that FIG. 1 shows a configuration in which the sub-deflection angle S2 is 25 degrees as a reference value.

The number of injection holes per group in the first injection hole group 111, the second injection hole group 112, the third injection hole group 113, and the fourth injection hole group 114 may be arbitrarily set as long as it is three or more. Further, the number of groups may be set arbitrarily, and as long as the injection holes are arranged in a manner that the injection holes are shifted by a predetermined angle in each of the latitude and longitude directions, the injection holes may be arranged in a continuous line without being divided into groups. . However, it is preferable that the changes in the latitude and longitude directions are all in the same direction, such as when the injection hole moves clockwise from the equator side to the pole side.

The liquid sending component 2 may be provided with a seal on the end surface of the inlet 21 on the side of the pipe T1. As a result, the connection part connected to the pipe T1 at the inlet 21 is sealed, and leakage of the cleaning liquid sent in is prevented.

Hereinafter, a method of implementing the present invention will be described in detail using the drawings. Further, the implementation method shown below is an example, and the implementation method is not limited to this, and the order may be changed.

≪Implementation method≫
As shown in FIG. 5, the user first attaches the cleaning device X to the tip of the pipe T1 that introduces the cleaning liquid into the tank T. During this installation, the tip of the pipe T1 is inserted into the introduction port 21 of the liquid feeding component 2. If threads are provided at the tip of the inlet 21 and the pipe T1, they are fixed by tightening the screws.

During cleaning, the user feeds a predetermined cleaning liquid, such as pure water or co-washing chemicals, into the cleaning device X. At this time, the flow rate of the cleaning liquid is adjusted so that the sprayed cleaning liquid appropriately hits the inner wall surface of the tank T.
