Description

[Technical field]

[0001] The present invention relates to a cleaning device and a storage device with cleaning function, and more particularly to a cleaning device that cleans by spraying a fluid onto a surface of an object to be cleaned, and a storage device with cleaning function that is equipped with the cleaning device. [Background technology]

[0002] Conventionally, in a storage device having a container with a storage space, when replacing the contents stored in the container, a fluid such as a cleaning liquid is sprayed onto the inner surface of the container to clean it. As a cleaning device for cleaning the container in such a case, for example, one equipped with a cleaning nozzle is known (see Patent Document 1 below). As such a cleaning nozzle, one that is commercially available under the product name Spray Ball is known.

[0003] Furthermore, when a container has a lid that covers an opening or is used with piping connected to introduce the contents, a cleaning device equipped with a ring-shaped cleaning device body as described in Patent Document 2 below is used to clean the lid and piping.

[0004] [Patent Document 1] Patent No. 6926137 [Patent Document 2] Patent No. 6542561 Summary of the Invention [Problem to be solved by the invention]

[0005] The object to be cleaned by the above-mentioned cleaning device is not limited to a container and is diverse. In general, spraying of a fluid onto the surface of the object to be cleaned from a direction close to vertical is more likely to produce a strong impact force and a good cleaning effect. However, the cleaning device cannot always be positioned freely relative to the object to be cleaned, and the fluid outlet may not be positioned at a position where such spraying is possible. Furthermore, there may be an intervening object between the outlet and the surface to be cleaned that blocks the fluid, making it difficult to spray the fluid directly onto the surface to be cleaned. Therefore, it is difficult to fully exert the cleaning effect with the conventional cleaning device or the storage device with cleaning function that is equipped with the cleaning device. The present invention has been made with the aim of solving such problems, and the object is to improve the cleaning effect of the cleaning device and the storage device with cleaning function. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides: A cleaning device that cleans by spraying a fluid onto a surface of a cleaning object, A plurality of blowing ports for blowing out the fluid are provided, The plurality of air outlets include a plurality of collision air outlets in which the air-ejected fluids collide with each other, The fluid is blown out from the collision outlet and collides with the surface to be cleaned.

[0007] In order to solve the above problems, the present invention provides: A storage device with a cleaning function, comprising: a storage device having a container having a storage space; and a cleaning device that cleans the storage device by spraying a fluid from inside the container, The cleaning device includes: The cleaning device is configured to clean the surface to be cleaned by spraying a fluid onto the surface to be cleaned of the storage device, A plurality of blowing ports for blowing out the fluid are provided, The plurality of air outlets include a plurality of collision air outlets in which the air-ejected fluids collide with each other, The fluid is blown out from the collision outlet and collides with the surface to be cleaned, thereby providing a storage device with a cleaning function. Effect of the Invention

[0008] In the present invention, the fluid blown out from the multiple blowing ports collides with each other and is sprayed onto the surface to be cleaned in the storage device. Therefore, in the present invention, the moving direction of the fluid blown out from the blowing ports can be changed by the collision, and the angle at which the fluid is sprayed onto the surface to be cleaned can be made different from the case where the fluid is sprayed directly. Also, in the present invention, the fluid can be sprayed onto the surface to be cleaned that is in a position hidden from the blowing ports. Therefore, according to the present invention, the cleaning effect of the cleaning device and the storage device with cleaning function can be improved. [Brief description of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The storage device with cleaning function of this embodiment includes a storage device equipped with a container having a storage space, and a cleaning device that cleans the storage device by spraying a fluid from the inside of the container. The specific form of the storage device with cleaning function of this embodiment is not particularly limited, but the embodiment of the present invention will be described below using a specific example. More specifically, the embodiment of the present invention will be described below using the example in which the storage device in the storage device with cleaning function is a reaction device used in a chemical process. In other words, the cleaning device of this embodiment can be used as equipment and / or its associated equipment used in a chemical process that changes in some way chemical substances or compounds contained in the contents stored in the storage device.

The storage device with cleaning function may be a processing device (mixing device, stirring device, filtering device, drying device, etc.) in which a physical process such as mixing, stirring, filtering, or drying is performed. These devices may be ones that perform both a chemical reaction and a physical process, or ones that perform only a physical process.

[0013] Fig. 1 shows an example of a storage device with a cleaning function in this embodiment, and the storage device with a cleaning function 100 illustrated in the figure includes a storage device having a container for storing objects to be stored, and a cleaning device that cleans the storage device by spraying a fluid from inside the container. In the storage device with a cleaning function 100 illustrated in the figure, the storage device is a reaction device 1 used in a chemical process, and the container is a reaction tank 10 with a glass lining. The cleaning device 2 in the storage device with a cleaning function 100 has a cleaning ring 20 for cleaning the inner surface of the reaction tank 10 by spraying a fluid thereon.

[0014] In the storage device 100 with cleaning function illustrated in the figure, the reaction tank 10 (container) is the object to be cleaned by the cleaning device 2. The reaction tank 10 of this embodiment is a glass-lined product in which glass is baked onto the surface of a metal base material to form a glass layer. The reaction tank 10 is provided with a tank body 11 as a container body constituting the main body. The tank body 11 has an opening at the top and is provided with a storage space 110 for storing objects to be stored. The reaction tank 10 illustrated in the figure is provided with a tank body 11 (container body) and a lid 12 for closing the opening of the tank body 11.

[0015] In the following, an example will be given in which the main object to be cleaned is the lid 12. In the lid 12, the inner surface 12a exposed to the accommodation space 110 is the surface to be cleaned.

[0016] The reaction tank 10 is provided with a glass lining at the portion exposed to the storage space 110 for storing the object to be stored, thereby imparting corrosion resistance. The tank body 11 in the reaction tank 10 is a vertical tank having a cylindrical shape with a bottom. The tank body 11 includes a bottom wall portion 111 which is circular in plan view, a peripheral side wall portion 112 which is cylindrical and extends upward from the outer periphery of the bottom wall portion 111, and a ceiling wall portion 113 which is circular in plan view and is arranged to face the bottom wall portion 111 in the vertical direction and close the upper end portion of the peripheral side wall portion 112.

[0017] The central axis Cx0 of the tank body 11 passes through the center of the cylindrical peripheral side wall portion 112 and extends in the vertical direction. The tank body 11 is disposed in the reaction device 1 so that the central axis Cx0 is oriented in the vertical direction. In the following, the direction along the central axis Cx0 may be referred to as the height direction H, the vertical direction, etc. In addition, in the following, the direction going around the central axis Cx0 may be referred to as the circumferential direction R, etc. Furthermore, in the following, the direction passing through the central axis Cx0 and perpendicular to the central axis Cx0 may be referred to as the radial direction D, etc.

[0018] The reaction tank 10 illustrated in the figure has three openings on the upper side. The reaction tank 10 has three container nozzle parts 114 that define the openings by their upper edges. The three container nozzle parts 114 extend upward in a cylindrical shape from three openings provided in the ceiling wall part 113. The three container nozzle parts 114 are arranged side by side from one end side to the other end side in the left-right direction of the ceiling wall part 113, and the first container nozzle part 114 (hereinafter also referred to as the "first container nozzle part 114a") provided on the left side as viewed from the front of FIG. 1 can be used as a manhole, and can be used for putting in and taking out the contained objects and checking the internal state of the reaction tank 10. The cleaning device 2 in this embodiment is attached to the first container nozzle part 114a.

[0019] The stirring device 13 is attached to the second container nozzle portion 114 (hereinafter also referred to as "second container nozzle portion 114b") located in the center when viewed from the front in Figure 1, and a baffle 14 is attached to the third container nozzle portion 114 (hereinafter also referred to as "third container nozzle portion 114c") on the right side when viewed from the front in Figure 1.

[0020] First container nozzle portion 114a, second container nozzle portion 114b, and third container nozzle portion 114c each include a cylindrical portion extending cylindrically from ceiling wall portion 113, and a flange portion extending outward from the upper edge of the cylindrical portion.

[0021] As described above, the tank body 11 of this embodiment has three container nozzle portions 114. The storage space 110 of the tank body 11 includes a main space portion 11m defined by a bottom wall portion 111, a peripheral side wall portion 112, and a ceiling wall portion 113, and a space portion inside the container nozzle portion 114 that communicates with the main space portion 11m. That is, the storage space 110 of the tank body 11 includes a first space portion 11a which is the internal space of the first container nozzle portion 114a, a second space portion 11b which is the internal space of the second container nozzle portion 114b, and a third space portion 11c which is the internal space of the third container nozzle portion 114c.

[0022] Each of the first space 11a, the second space 11b, and the third space 11c is connected to the main space 11m so as to protrude upward from the upper end of the main space 11m in a cylindrical shape. In other words, the first container nozzle 114a, the second container nozzle 114b, and the third container nozzle 114c each have an inner surface that defines a space protruding upward from the upper end of the main space 11m. In addition, the cover 12 that closes the upper opening of the first container nozzle 114a has an inner surface 12a that defines the upper edge of the first space 11a that protrudes upward from the main space 11m.

[0023] As described in detail later, the cleaning device 2 of this embodiment is provided with a cleaning ring 20 having an outlet for blowing out a cleaning fluid. In the cleaning-function-equipped storage device 100, the cleaning ring 20 is attached to the upper end of the first container nozzle portion 114a. That is, in this embodiment, the upper opening of the first container nozzle portion 114a serves as the cleaning device mounting port 10a. Also, in this embodiment, the upper opening of the second container nozzle portion 114b and the upper opening of the third container nozzle portion 114c serve as the agitator mounting port 10b and the baffle mounting port 10c, respectively.

[0024] The agitator mounting opening 10b opens approximately at the center of the ceiling wall portion 113. The cleaning device mounting opening 10a and the baffle mounting opening 10c are arranged on the left and right sides with the agitator mounting opening 10b therebetween.

[0025] The cleaning ring 20 is attached to the upper end of the first container nozzle part 114a in the height direction H so as to slightly extend the cylindrical part (hereinafter also referred to as the "first cylindrical part 114a1") of the first container nozzle part 114a. The first container nozzle part 114a has a flange part (hereinafter also referred to as the "first flange part 114a2") that extends outward from the upper end edge of the cylindrical part (first cylindrical part 114a1). The outer diameter of the first flange part 114a2 is approximately the same as the outer diameter of the lid body 12. The cleaning ring 20 is sandwiched between the first flange part 114a2 and the lid body 12 and its position relative to the tank body 11 is fixed.

[0026] The cylindrical portion of the second container nozzle portion 114b (hereinafter also referred to as "second cylindrical portion 114b1") is used to insert the rotating shaft 131 of the stirring device 13. The rotating shaft 131 extends vertically through the center of the second cylindrical portion 114b1, has a stirring blade 132 fixed to its lower end, and is arranged so that the stirring blade 132 can be rotated by rotating around the axis. The second container nozzle portion 114b has a flange portion (hereinafter also referred to as "second flange portion 114b2") extending outward from the upper end edge of the cylindrical portion (second cylindrical portion 114b1) in the same manner as the first container nozzle portion 114a.

[0027] The cylindrical portion of the third container nozzle portion 114c (hereinafter also referred to as the "third cylindrical portion 114c1") is used to insert the baffle 14 as described above. The third container nozzle portion 114c also has a flange portion (hereinafter also referred to as the "third flange portion 114c2") that extends outward from the upper end edge of the cylindrical portion (third cylindrical portion 114c1). The baffle 14 is fixed to the tank body 11 by the third flange portion 114c2.

[0028] The agitator 13 is disposed so that the axis of the rotating shaft 131 coincides with the central axis Cx0 of the tank body 11. Therefore, in this embodiment, the second cylindrical portion 114b1 extends upward from the ceiling wall portion 113 so that the direction of the central axis is vertical. The third container nozzle portion 114c also extends upward from the ceiling wall portion 113 so that the central axis extends vertically, similar to the second container nozzle portion 114b. On the other hand, the central axis of the first container nozzle portion 114a is inclined with respect to the vertical direction. The central axis Ca of the first container nozzle portion 114a is inclined so as to move away from the central axis Cx0 of the tank body 11 in the radial direction D as it moves upward in the height direction H. That is, the first container nozzle portion 114a is erected in a state inclined outward.

[0029] The lid body 12 of this embodiment is a disk shape corresponding to the outer contour shape of the first flange portion 114a2. As shown in Figures 2 and 3, the cleaning ring 20 of this embodiment includes a ring body 21 having a size corresponding to the first flange portion 114a2 and a plurality of protruding pieces 22 protruding radially outward from the ring body 21. The lid body 12 is attached to the first container nozzle portion 114a via the ring body 21. The lid body 12 is attached via a hinge HG, and is provided so as to be capable of taking a closed state in which the opening of the first container nozzle portion 114a is closed and an open state in which the opening is released by rotating via the hinge HG.

[0030] The lid body 12 is not directly fixed to the first container nozzle portion 114a, but is fixed to the ring body 21 of the cleaning ring 20 via the hinge HG. The lid body 12 is indirectly fixed to the first container nozzle portion 114a by fixing the ring body 21 to the first flange portion 114a2 with a clamp CL1. In this embodiment, the ring body 21 is fixed to the first container nozzle portion 114a by fixing the protruding piece 22 and the first flange portion 114a2 of the first container nozzle portion 114a with a clamp CL1. In this embodiment, a second clamp CL2 (second clamp) is used to fix the ring body 21 to the first flange portion 114a2, which is different from the clamp CL1 (first clamp), in order to maintain the closed state of the lid body 12 fixed to the first container nozzle portion 114a so as to be freely opened and closed by the clamp CL1.

[0031] As described above, the lid body 12 in this embodiment is not directly fixed to the first container nozzle portion 114a, but is fixed to the first container nozzle portion 114a via the cleaning ring 20. In this embodiment, the cleaning ring 20 is detachable from the first container nozzle portion 114a. Therefore, the lid body 12 is also detachable from the first container nozzle portion 114a.

[0032] The lid body 12 shown in the figure is attached to the first container nozzle portion 114a so that the hinge HG is located radially inward (closer to the central axis Cx0 of the tank body) than the opening of the first container nozzle portion 114a, but it may also be attached to the first container nozzle portion 114a, for example, so that the hinge HG is located outer than the opening.

[0033] As described above, the lid 12 can be changed between a first mounting position in which the hinge HG is located radially inward from the opening of the first container nozzle portion 114a, and a second mounting position in which the hinge HG is located radially outward from the opening. Since the first container nozzle portion 114a is tilted outward as described above, for example, when the lid 12 is arranged in the second mounting position so that the hinge HG is located at the outermost position in the radial direction D, the lid 12 stands vertically when the sum of the opening angle θ1 of the hinge HG and the inclination θ2 of the first container nozzle portion 114a (inclination with respect to the vertical direction) is 90 degrees. If the opening angle θ1 is further increased, the lid 12 will stably maintain the open state due to its weight. In this case, there is a low risk that the lid 12 will be inadvertently closed by touching it during work through the manhole, which has the advantage of making the work easier to perform.

[0034] When the lid body 12 is disposed in the first mounting position, it has an advantage that it is easy to prevent the deposits adhering to the inside from scattering around the first container nozzle portion 114a when the lid body 12 is opened. For example, when droplets are attached to the inside of the lid body 12, in the second mounting position, the inclination of the lid body 12 increases from the point when the lid body 12 starts to be opened, so that the droplets may move along the inner surface of the lid body 12, and the droplets may fly out from the edge of the lid body 12 and fall onto the ceiling wall portion 113. On the other hand, in the first mounting position, such movement of the droplets does not start until the lid body 12 is opened to a certain extent, so that the droplets can be wiped off or dropped into the tank through the opening before they scatter around.

[0035] When viewed from the front side, the lid body 12 in the closed state covers almost the entire ring body 21 of the cleaning ring 20. The inner surface 12a of the lid body 12 has an annular region arranged along the outer periphery that is a covered region that is covered from the inside by the ring body 21, and an inner circular region surrounded by the covered region is an exposed region that is exposed to the first space 11a. Therefore, in this embodiment, there is a possibility that a part of the contained object, agglomerates of volatile substances generated from the contained object, etc. may adhere to the exposed region.

[0036] The lid 12 of this embodiment is provided with a glass window 12w so that the state of the contents inside the reaction tank 10 can be visually confirmed from the outside of the reaction tank 10 when the lid is closed. That is, the lid 12 of this embodiment is configured so that the occurrence of adhesion to the inner surface can be confirmed without opening the lid 12. The lid 12 of this embodiment has a shape that protrudes upward at the center, and the glass window 12w is provided in the protruding portion.

[0037] The cover 12 of this embodiment includes a doughnut-shaped base plate 121. The base plate 121 is dome-shaped with a portion closer to the center than the outer periphery bulging upward, and an opening is provided in the center. The cover 12 includes a cylindrical portion 122 extending from the opening of the base plate 121 in a cylindrical shape, a flange portion 123 extending outward from the upper end edge of the cylindrical portion 122, a glass plate 124 abutting against the flange portion 123 so as to close the upper opening of the cylindrical portion 122, and an annular window frame portion 125 for sandwiching the glass plate 124 between the flange portion 123 and the glass plate 124. The inside of the window frame portion 125 is the glass window 12w.

[0038] As described above, the cover 12 defines the upper edge of the first space 11a protruding upward from the main space 11m. The opening of the base plate 121 and the cylindrical portion 122 are smaller than the inner diameter of the ring body 21 and the first container nozzle portion 114a. The cover 12 includes the cylindrical portion 122, so that the first space 11a has a shape that protrudes from the main space 11m and further protrudes smaller at the upper end. The upper edge of the first space 11a, which protrudes in two stages by the first container nozzle portion 114a and the cylindrical portion 122 of the cover 12, is defined by the glass plate 124 that constitutes the glass window 12w.

[0039] The cylindrical portion 122 extends in a direction along the central axis Ca of the first container nozzle portion 114a and extends obliquely upward. The cylindrical portion 122 illustrated in the figure is provided so that its central axis coincides with the central axis Ca of the first container nozzle portion 114a, but the cylindrical portion 122 of this embodiment may be provided so that its central axis does not coincide with the central axis Ca of the first container nozzle portion 114a.

[0040] The cleaning device 2 of this embodiment is used, for example, to improve the visibility of the glass window 12w. Surfaces to be cleaned by the cleaning device 2 of this embodiment include the inner surface (lower surface) of the glass plate 124 exposed to the first space portion 11a, the inner peripheral surface of the cylindrical portion 122, and the inner surface of the substrate portion 121. The cleaning device 2 includes the cleaning ring 20 as described above. The cleaning device 2 includes a fluid supply unit 20a for supplying the cleaning fluid to the cleaning ring 20. The fluid supply unit 20a may be composed of a pump 20a1 that serves as a transport power for the fluid, a pipe 20a2 that serves as a transport path for the fluid to the cleaning ring 20, and the like.

[0041] The cleaning ring 20 has an annular ring body 21 as shown in Figures 2 and 3. The cleaning ring 20 is provided in the reaction apparatus 1 with the ring body 21 disposed above the upper edge of the first vessel nozzle part 114a that defines the upper opening of the reaction tank 10. The ring body 21 is sandwiched between the base plate part 121 of the lid body 12 and the first flange part 114a2 so as to surround the opening, and is fixed to the first vessel nozzle part 114a.

[0042] The cleaning ring 20 is disposed so that the central axis Ca of the first container nozzle portion 114a and the central axis 21c of the ring body 21 coincide with each other, and is used with the ring body 21 tilted relative to the horizontal plane.

[0043] The cleaning ring 20 in this embodiment is used for cleaning by spraying a fluid (for example, a cleaning liquid) from the inner periphery side to remove deposits adhering to the glass plate 124, the substrate portion 121, and the like.

[0044] When a cleaning liquid is used as a cleaning fluid, the cleaning liquid may be a solution in which a solute is dissolved in a solvent such as water or an organic solvent, or may be a dispersion containing suspended solids. The cleaning liquid may further contain air bubbles such as microbubbles in addition to the solute and suspended solids. In this embodiment, the cleaning liquid is blown out from the cleaning ring 20, but the fluid blown out from the cleaning ring 20 is not limited to a liquid and may be a particulate solid. In addition to cleaning materials such as liquids and solids (liquid materials, granular materials), gases may be used as the fluid. That is, in this embodiment, nitrogen gas or carbon dioxide gas may be used as the fluid, and the cleaning ring 20 may be used to perform cleaning with an airflow caused by the gas. The fluid may contain particles of the cleaning material in the airflow. That is, a specific mode in which the cleaning material is blown out from the cleaning ring 20 may be an airflow containing liquid particles (mist spray) or an airflow containing solid particles (powder spray). A specific embodiment in which the cleaning material is sprayed from the cleaning ring 20 may be a liquid containing solid particles (slurry) or a liquid containing air bubbles (gas-liquid mixed fluid).

[0045] The type and pressure of the fluid can be changed depending on the desired effect in the cleaning ring 20. To obtain a good cleaning effect, the pressure of the fluid in the cleaning ring 20 can be, for example, 100 kPa or more in gauge pressure.

[0046] The ring body 21 of the cleaning ring 20 in this embodiment is a hollow ring. That is, the ring body 21 has a space 21a inside. The space 21a is used as a flow path for the cleaning liquid. The space 21a in this embodiment is continuous in the circumferential direction Dr of the ring body 21, and is provided so as to pass through the inside of the ring body 21 and go around the central axis 21c of the ring body 21. That is, the ring body 21 in this embodiment has an annular flow path through which the cleaning liquid flows.

[0047] The cleaning ring 20 in this embodiment has an axial direction Dx that is a direction along the central axis 21c of the ring body 21. The cleaning ring 20 further has a radial direction Dd that passes through the central axis 21c of the ring body 21 and is perpendicular to the central axis 21c. The cleaning ring 20 further has a circumferential direction Dr that is a direction going around the central axis 21c of the ring body 21.

[0048] When the ring body 21 is arranged so that the axial direction Dx is a vertical direction (perpendicular direction) and the radial direction Dd is a horizontal direction, the cross-sectional shape of the ring body 21 in a plane perpendicular to the circumferential direction Dr is a horizontally long rectangle. The cross-sectional shape is a rectangle whose dimension in the axial direction Dx is slightly smaller than its dimension in the radial direction Dd. As shown in the figure, the space portion 21a is located toward the inside in the radial direction Dd.

[0049] The cleaning ring 20 has a through hole penetrating an inner peripheral wall 211 of the ring body 21 that defines the space 21a of the ring body 21 from the inside in the radial direction Dd. In this embodiment, the through hole communicates the space 21a with the first space 11a and serves as an outlet 20h that blows the cleaning liquid supplied to the space 21a toward the inside in the radial direction Dd of the ring body 21.

[0050] In the following, the direction in which this air outlet 20h penetrates from the space 21a toward the first space 11a is referred to as the direction in which the fluid is blown out, and this direction is also referred to as the "fluid blowing direction" or simply the "blowing direction".

[0051] The air outlet 20h may be formed so that the opening diameter when viewed in the opposite direction to the air outlet direction is, for example, 0.5 mm or more. The opening diameter (diameter) of the air outlet 20h may be, for example, 0.7 mm or more, or 1 mm or more. The opening diameter (diameter) may be, for example, 5 mm or less. The opening diameter (diameter) may be 4 mm or less, or 3 mm or less.

[0052] The cleaning ring 20 has a plurality of the air outlets 20h. The plurality of air outlets 20h may have the same opening diameter or may have different opening diameters.

[0053] The plurality of outlets 20h include a plurality of collision outlets 20h1 where the blown fluids collide with each other. The cleaning ring 20 is configured so that the fluids blown out from the collision outlets 20h1 and collide with each other are sprayed onto the inner surface of the glass plate 124.

[0054] All of the outlets 20h provided in the cleaning ring 20 may be collision outlets 20h1, or some of them may be collision outlets 20h1. In this embodiment, the cleaning ring 20 is provided with a non-collision outlet 20h2 that blows out the fluid in a direction different from the collision point of the fluid blown out from the collision outlet 20h1.

[0055] In order to ensure a certain level of flow rate and flow velocity of the fluid after collision, it is preferable that three or more collision air outlets 20h1 are provided. The number of collision air outlets 20h1 may be four or more, five or more, or ten or more, depending on the size of the ring body 21. The number of collision air outlets 20h1 may be, for example, 40 or less.

[0056] In this embodiment, the inner surface of the glass plate 124, which is the surface to be cleaned, is located deeper than the inner surface of the base portion 121 of the lid 12. Therefore, as shown in Fig. 4, the inner surface 12a of the lid 12 includes an area that is hidden from any of the collision air outlets 20h1 (hereinafter, also referred to as a hidden area 12a1). Unlike an area that can be seen through the collision air outlet 20h1 (hereinafter, also referred to as a visible area 12a2), it is difficult to directly spray a fluid from the collision air outlet 20h1 onto the hidden area 12a1.

[0057] In this embodiment, among the surfaces to be cleaned, which include the inner surface of the glass plate 124, the inner circumferential surface of the cylindrical portion 122, and the inner surface of the base portion 121, the tip side portion of the inner circumferential surface of the cylindrical portion 122 close to the glass plate 124 and the inner surface of the glass plate 124 are hidden by the base portion 121 and form a hidden region 12a1 that is hidden from view from any of the impingement air outlets 20h1. On the other hand, the inner surface of the base portion 121 and the inner circumferential surface of the cylindrical portion 122 on the base end side form a visible region 12a2.

[0058] The non-collision outlet 20h2 in this embodiment is arranged to directly blow the fluid onto the line-of-sight region 12a2. In this embodiment, a first non-collision outlet 20h2 that directly blows the fluid onto the inner surface of the substrate portion 121 and a second non-collision outlet 20h2 that directly blows the fluid onto the inner circumferential surface of the cylindrical portion 122 may be provided.

[0059] When four or more collision air outlets 20h1 are provided, the fluids may collide at a plurality of locations. For example, the fluids blown out from two or more collision air outlets 20h1 may collide at one location, and the fluids blown out from two or more other collision air outlets 20h1 may collide at another location.

[0060] The collision air outlets 20h1 in this embodiment are arranged on the inner circumferential surface of the ring body 21 at equal intervals in the circumferential direction Dr. The non-collision air outlets 20h2 in this embodiment are arranged on the inner circumferential surface of the ring body 21 at equal intervals in the circumferential direction Dr. The interval between the collision air outlets 20h1 and the non-collision air outlets 20h2 in the circumferential direction can be, for example, 30 mm or more and 100 mm or less. The interval may be 40 mm or more, or 50 mm or more. The interval may be 90 mm or less, 80 mm or less, or 70 mm or less.

[0061] The ratio of the collision air outlets 20h1 provided at equal intervals when the total number of the collision air outlets 20h1 is taken as 100% may be 50% or more, 75% or more, or 90% or more. The ratio of the collision air outlets 20h1 provided at equal intervals may be 100%. Similarly, the ratio of the non-collision air outlets 20h2 provided at equal intervals when the total number of the non-collision air outlets 20h2 is taken as 100% may be 50% or more, 75% or more, or 90% or more. The ratio of the non-collision air outlets 20h2 provided at equal intervals may be 100%.

[0062] As described above, the multiple collision outlets 20h1 in this embodiment may include collision outlets 20h1 arranged at equal intervals in the circumferential direction Dr and collision outlets 20h1 that are not arranged at equal intervals. In this embodiment, the intervals between the collision outlets 20h1 arranged at equal intervals may be adjusted to collide the fluid and move it in a desired direction, or the number of the collision outlets 20h1 that are not arranged at equal intervals may be adjusted, or the hole diameter of each may be made variable. In addition, the collision point of the fluid blown out from the collision outlet 20h1 may be the center of the ring body 21 or a position off the center.

[0063] The cleaning ring 20 of this embodiment may have a ring body 21 formed of, for example, a plurality of orifice plates each having a through hole that can be used as the air outlet 20h, and a hollow annular member having a plurality of orifice mounting holes on the inner periphery to which the orifice plates can be attached. A plurality of types of orifice plates having different hole penetration directions (angles) relative to the plate surface and hole diameters are prepared, and threads and thread grooves that screw into the outer periphery of the orifice plates and the orifice mounting holes are formed, so that a plurality of types of orifice plates can be freely replaced with respect to one orifice mounting hole. This makes it possible to form a cleaning ring 20 in which the arrangement of the collision air outlet 20h1 and the non-collision air outlet 20h2 can be freely adjusted.

[0064] The collision air outlets 20h1 and non-collision air outlets 20h2 arranged at equal intervals may be arranged such that the opening angle between adjacent ones in the axial view seen from the direction along the central axis 21c of the ring body 21 is, for example, 9 degrees or more and 120 degrees or less. That is, for example, three or more collision air outlets 20h1 and non-collision air outlets 20h2 arranged at equal intervals may be provided in the ring body 21 (360 degrees / 120 degrees). Also, for example, 40 or less collision air outlets 20h1 and non-collision air outlets 20h2 arranged at equal intervals may be provided in the ring body 21 (360 degrees / 9 degrees).

[0065] The interval between adjacent collision outlets 20h1 and the interval between adjacent non-collision outlets 20h2 in the circumferential direction Dr may be the same or different. That is, the number of collision outlets 20h1 arranged at equal intervals and the number of non-collision outlets 20h2 arranged at equal intervals may be the same or different.

[0066] The direction of movement (path) of the fluid is usually determined uniquely by the dynamic pressure or gravity when the fluid is blown out from the blowing outlet 20h, and the path may change downward due to the action of gravity during the movement, but it does not change sideways or upwards. In this embodiment, the fluid blown out from one collision blowing outlet 20h1 and the fluid blown out from another collision blowing outlet 20h1 collide with each other, and at least a part of each fluid moves in a different direction from before the collision. Therefore, the fluid, which does not change direction in the middle to a different direction from the blowing direction if it is simply moving through the air, can be moved so as to bend upward or sideways. Therefore, in this embodiment, the fluid can be blown out to the hidden area 12a1 where it is difficult to blow the fluid.

[0067] As shown in FIG. 5, the multiple collision outlets 20h1 include one collision outlet 20h1' and another collision outlet 20h1" different from the one collision outlet 20h1', and the one collision outlet 20h1' and the other collision outlet 20h1" may be arranged such that a virtual line RL1 extending from the one collision outlet 20h1' in the direction in which the fluid is blown out (fluid blowing direction) and a virtual line RL2 extending from the other collision outlet 20h1" in the direction in which the fluid is blown out (fluid blowing direction) intersect at a right angle or diagonally.

[0068] It is preferable that the angle (θx) between the virtual line RL1 from the intersection O where the virtual lines (RL1, RL2) intersect to one collision air outlet 20h1', and the virtual line RL2 from the intersection O to the other collision air outlet 20h1" is 170 degrees or less. The angle (θx) may be 160 degrees or less, or 150 degrees or less. The angle (θx) can be, for example, 90 degrees or more. In this embodiment, it is preferable that the angle (θx) at the two collision air outlets 20h1 that are positioned opposite each other via the central axis 21c be the value described above.

[0069] With respect to the first collision outlet 20h1' and the second collision outlet 20h1", when a virtual plane RP1 passing through each of the collision outlets 20h1 is set among planes perpendicular to the axial direction Dx, it is preferable that a virtual line RL1 extending from the first collision outlet 20h1' in the fluid blowing direction and a virtual line RL2 extending from the second collision outlet 20h1" in the fluid blowing direction are each inclined with respect to the virtual plane RP1. The angles (elevation angles θy', θy") that each virtual line (RL1, RL2) makes with respect to the virtual plane RP1 may be the same or different. For example, when each virtual line (RL1, RL2) is inclined toward the glass plate 124, it becomes easier to move much of the fluid after collision toward the glass plate 124.

[0070] To explain this in detail, the glass plate 124 defines the leading edge in the protruding direction of the first space portion 11a, and is arranged so that the normal direction of the inner surface faces downward (diagonally downward). Therefore, in order to clean the lower surface of the glass plate 124, it is effective to spray a fluid moving upward.

[0071] When the fluid is blown out from only one blowing outlet 20h, the fluid may change its moving direction downward due to the action of gravity, but it will not change to an upward direction. In addition, even when the fluid is blown out from a plurality of blowing outlets 20h, if each fluid forms an independent flow, the flow direction will not change to an upward direction. On the other hand, when the fluids are made to collide with each other, the inertial force before the collision can be utilized to change the flow of the fluid after the collision to an upward direction. The cleaning device 2 of this embodiment can perform good cleaning even on a surface to be cleaned in which the normal direction of the hidden area 12a1 is downward as described above.

[0072] If two fluids collide head-on with their inertial forces in completely opposite directions, the momentum of the fluids after the collision will be greatly weakened. For this reason, it is preferable to collide the fluids at right angles or diagonally.

[0073] It is preferable that the one collision air outlet 20h1' and the other collision air outlet 20h1" are arranged so that the intersection O is closer to the glass plate 124. As described above, the base portion 121 in this embodiment is dome-shaped and has a shape that bulges away from the ring main body 21 in the axial direction Dx from the outer circumferential edge portion in contact with the ring main body 21 toward the center. The lid body 12 of this embodiment, in which the base portion 121 has such a shape, makes it easier to bring the intersection O closer to the glass plate 124 than a lid body having a flat base portion. The one collision air outlet 20h1' and the other collision air outlet 20h1" are arranged so that the intersection O is closer to the glass plate 124 than the lower edge of the cylindrical portion 122.

[0074] The angles (θy', θy") made by each virtual line (RL1, RL2) with respect to the virtual plane RP1 may be the same or different. The angles (θy', θy") made by each virtual line (RL1, RL2) with respect to the virtual plane RP1 may be, for example, 5 degrees or more. The angles (θy', θy") may be 6 degrees or more, 8 degrees or more, 10 degrees or more, or 15 degrees or more. The angles (θy', θy") may be, for example, 50 degrees or less.

[0075] The angle between a virtual line extending from the non-collision outlet 20h2 in the blowing direction and the virtual plane RP1 may be the same as above. In this embodiment, the fluid blown out from the non-collision outlet 20h2 may be used to clean the inner surface of the substrate portion 121. In that case, the angle (the angle between the virtual plane RP1 and the blowing direction) may be larger than the angle at the collision outlet 20h1. For example, the multiple non-collision outlets 20h2 may include an angle that is 1.1 times or more the angle at the collision outlet 20h1, an angle that is 1.2 times or more, or an angle that is 1.5 times or more.

[0076] The collision outlet 20h1 can be arranged so that the central axis 21c passes through the collection point (collision point) of the fluid. That is, the blowing direction of the collision outlet 20h1 when viewed in the axial direction can be the radial direction Dd as shown in Figs. 6 and 7a. The blowing direction of the non-collision outlet 20h2 can also be the radial direction Dd. As shown in Fig. 7b, when the non-collision outlet 20h2 is used to blow the fluid onto the inner surface of the substrate 121, the blowing direction is preferably inclined at a predetermined angle (θd) with respect to the radial direction Dd. In that case, the blowing angle of the fluid onto the inner surface of the substrate 121 becomes shallow, and the fluid that hits the inner surface of the substrate 121 easily moves along the inner surface, making it difficult for unwashed areas to occur.

[0077] The angle (θd) between the blowing direction of the non-collision blowing outlet 20h2 and the radial direction Dd can be, for example, 5 degrees or more. The angle (θd) may be 10 degrees or more. The angle (θd) can be, for example, 45 degrees or less. The angle (θd) may be 40 degrees or less, or 35 degrees or less.

[0078] In this embodiment, the ring body 21 is arranged at an incline with respect to the horizontal direction. Therefore, even if the multiple collision outlets 20h1 are arranged at equal intervals on the ring body 21 in exactly the same state, the colliding fluid may not be sprayed to the center of the glass window 12w. In this embodiment, the first container nozzle part 114a to which the ring body 21 is attached is inclined outward with respect to the central axis Cx0 of the tank body 11 as described above. Therefore, even if the fluid collides at the position of the central axis 21c of the ring body 21, the fluid after the collision does not move straight along the central axis 21c but is inclined outward and may be sprayed outside the center of the glass window 12w.

[0079] In the above case, the amount of fluid blown may be less in the portion of the glass window 12w closer to the central axis Cx0 than in the portion farther away. If this is problematic, the shape, etc. of one collision outlet 20h1' and another collision outlet 20h1" among the multiple collision outlets 20h1 may be made different to change the amount or speed of the fluid blown out, thereby adjusting the direction of movement of the fluid after collision.

[0080] In this embodiment, the lid 12 and the ring body 21 are detachable from the first container nozzle portion 114a. In addition, in this embodiment, such attachment and detachment can be easily performed by the clamps CL1 and CL2. Therefore, in this embodiment, after performing the primary cleaning by spraying the fluid for a certain period of time, for example, the lid 12 can be temporarily removed, rotated 180 degrees around the central axis 21c of the ring body 21, and attached to the first container nozzle portion 114a again, and the spraying of the fluid can be resumed in this state to perform the secondary cleaning. As a result, a large amount of fluid can be sprayed in the secondary cleaning to the portion where the amount of fluid sprayed in the primary cleaning was small, and good cleaning can be performed.

[0081] As described above, the cleaning device 2 in this embodiment exhibits good cleaning function. Specifically, the collision outlet 20h1 may be a straight nozzle that blows the fluid in a columnar shape from the outlet. In the case of a straight nozzle, the directivity is high and it is easy to give a strong momentum to the fluid after collision. A specific embodiment of the non-collision outlet 20h2 may also be a straight nozzle. When a wide range of cleaning is prioritized, the non-collision outlet 20h2 may be a fan nozzle, an empty cone nozzle, a full cone nozzle, or the like.

[0082] (Other embodiments) In the above example, the lid body 12 is exemplified as the main object to be cleaned, but the cleaning device 2 of this embodiment is also effective when, for example, a pipe P1 is connected to the first container nozzle portion 114a via the ring body 21 of the cleaning ring 20 as shown in Fig. 8. In such a case, a fluid such as a cleaning liquid can be sprayed to a location relatively far away from the ring body 21 through the pipe P1.

[0083] The cleaning device 2 does not necessarily require the cleaning ring 20. For example, as shown in FIG. 9, a cleaning device 2 may be adopted in which a cleaning nozzle SN, also called a spray nozzle, is provided instead of the cleaning ring 20. Specifically, as shown in FIG. 10, the cleaning nozzle SN illustrated in the figure includes a fixed part N1 attached to the upper end of the container nozzle 114 and a hollow nozzle body part N2 extending downward from the fixed part N1. In the cleaning nozzle SN illustrated in the figure, the nozzle body part N2 includes a tubular part N21 extending cylindrically from the fixed part N1 and a hollow spherical head part N22 attached to the tip of the tubular part N21, and a plurality of blowing ports SNh are drilled in the head part N22. The fixed part N1 is connected to a piping 20a2 for supplying a fluid, and the supplied cleaning liquid flows through the inside of the nozzle body part N2 via the fixed part N1 and is blown out from the head part N22 provided at the tip of the nozzle body part N2. The cleaning nozzle SN is configured so that the supplied cleaning liquid is sprayed radially from the head portion N22 as multiple straight streams.

[0084] In the storage device 100 with cleaning function illustrated in Figure 9, a first cleaning nozzle (hereinafter also referred to as the "first cleaning nozzle SN1") is arranged in the first container nozzle portion 114a, and a second cleaning nozzle (hereinafter also referred to as the "second cleaning nozzle SN2") is arranged in the third container nozzle portion 114c, and the cleaning liquid blown out from the outlet SNh (collision outlet) of the first cleaning nozzle SN1 and the cleaning liquid blown out from the outlet SNh (collision outlet) of the second cleaning nozzle SN2 are collided below the second container nozzle portion 114b, so that the colliding cleaning liquid moves upward to clean the base portion of the rotating shaft 131.

[0085] 9, the conditions for supplying a fluid to the first cleaning nozzle SN1 and the conditions for supplying a fluid to the second cleaning nozzle SN2 can be set separately. For example, the types, concentrations, and temperature conditions of the components of the cleaning liquid sprayed from the first cleaning nozzle SN1 and the cleaning liquid sprayed from the second cleaning nozzle SN2 can be made different.

[0086] When there is a first fluid path that supplies fluid to one of the multiple impingement air outlets and a second fluid path that supplies fluid to the other impingement air outlets, one fluid may be a liquid and the other fluid may be a gas.

[0087] The cleaning device 2 is also effective for cleaning recesses in pipes. As shown in Fig. 11, a first pipe PL1 and a second pipe PL2 are connected at the main pipe of a Y-shaped joint YJ, which has a straight main pipe and a branch pipe that branches off obliquely from the main pipe, and a sensor such as a sheathed thermocouple TC is inserted from the branch pipe side to collect information inside the pipe. Material tends to accumulate in the branch pipe, and cleaning requires removing the sensor. In such a case, foreign matter may be allowed to enter from the outside. In such a case, as shown in the figure, a straight-line nozzle NZ with an outlet that sprays cleaning liquid in a column shape is placed in the middle of the first pipe PL1, and a cleaning nozzle SN3 that sprays cleaning liquid radially as described above is placed in the middle of the second pipe PL2.When it becomes necessary to clean the pipeline of the branch pipe, the cleaning liquid sprayed out from the outlet (collision outlet) of the straight-line nozzle NZ and the cleaning liquid sprayed out from the outlet (collision outlet) of the cleaning nozzle SN3 are made to collide at the point where the branch pipe branches off from the main pipe, and the cleaning liquid after the collision is allowed to enter the pipeline of the branch pipe.This eliminates the need to remove the sensor for work and the risk of foreign matter being mixed in from outside.

[0088] In addition to these examples, the storage device with cleaning function and the cleaning device of the present invention can adopt various aspects. For example, the above example shows cleaning a glass plate, but ensuring visibility is also required in situations where a resin plate such as an acrylic plate or a polycarbonate plate is used, and the cleaning device of this embodiment is effective for cleaning such a light-transmitting plate having light transmittance. The light transmittance required for a light-transmitting plate is not only important for the transmittance of visible light, but is also required in situations where the inside is observed using infrared light or ultraviolet light. Therefore, the cleaning device of this embodiment is also effective in improving the cleaning effect of a light-transmitting plate that transmits substantially only ultraviolet light or a light-transmitting plate that transmits only infrared light. Furthermore, the cleaning device of this embodiment is also effective for cleaning a member that does not have light transmittance.
