Description

Technical Field

[0001] The present invention relates to a cleaning device used for spraying a cleaning liquid onto a member for cleaning, a container provided with the cleaning device, and a method for cleaning a container using the cleaning device.

Background Art

[0002] The following Patent Document 1 discloses an example of a conventional cleaning device. This cleaning device includes a spherical fixed spray nozzle and a cleaning liquid supply pipe, and a plurality of cleaning liquid injection holes are formed in the fixed spray nozzle. When using this cleaning device to clean an object to be cleaned, the cleaning liquid is supplied from the cleaning liquid supply pipe to the fixed spray nozzle. Then, the cleaning liquid is linearly sprayed from the plurality of cleaning liquid injection holes toward the object to be cleaned.

[0003] In this cleaning device, since the cleaning liquid linearly sprayed from the cleaning liquid injection holes hits the surface of the object to be cleaned in a dot-like manner, in order to clean a wide range of the member, it is necessary to increase the number of cleaning liquid injection holes. Also, in order to clean an object to be cleaned far from the cleaning device, it is necessary to increase the inner diameter of the cleaning liquid injection holes. However, increasing the number of cleaning liquid injection holes and increasing the inner diameter of the cleaning liquid injection holes have the problem that the consumption amount of the cleaning liquid increases.

[0004] As a means for reducing the consumption amount of the cleaning liquid, it is conceivable to increase the inner diameter of the cleaning liquid injection holes directed toward an object to be cleaned far from the cleaning device and decrease the inner diameter of the cleaning liquid injection holes directed toward an object to be cleaned close to the cleaning device. However, in this case, in order to sufficiently clean an object to be cleaned close to the cleaning device, it is necessary to increase the number of cleaning liquid injection holes with a small inner diameter, and there is a problem that the design cost becomes high.

Patent Document 1

[0006] The present invention was made to address the above-mentioned problems, and its objective is to provide a cleaning device, a container, and a method for cleaning a container that can clean a wide range of components while keeping design costs down.

[0007] To achieve the above objective, the cleaning device according to the present invention is characterized by a cleaning device for cleaning a member with a cleaning liquid, comprising: a cleaning device body having a wall portion constituting a pressure chamber; a cleaning liquid supply port provided in the wall portion for supplying cleaning liquid to the pressure chamber; at least one diffusion spray portion provided in the wall portion for diffusing and spraying the cleaning liquid from the pressure chamber toward the member; at least one linear spray portion provided in the wall portion for linearly spraying the cleaning liquid from the pressure chamber toward the member; and a straight tubular cleaning liquid supply pipe connected to the cleaning liquid supply port, wherein the diffusion spray portion sprays the cleaning liquid linearly and the sprayed cleaning liquids collide with each other. death spread vinegar A pair formed on the wall portion circular Having a first injection hole, the linear injection section has one formed on the wall so as to spray the cleaning liquid in a straight line circular The wall portion has a second injection hole, and when a virtual straight line extending outward in the thickness direction of the wall portion from the outer surface of any portion of the wall portion is used as a reference line, and a virtual plane perpendicular to the center line of the cleaning fluid supply pipe, including the base point of the reference line located on the outer surface, is used as the reference plane, the wall portion has a first portion in which the reference line is inclined toward the cleaning fluid supply pipe with respect to the reference plane, and at least one of the diffusion injection portions is provided in the first portion. The pair of first injection holes are formed such that their centerlines are inclined toward the cleaning fluid supply pipe with respect to the reference plane, and these centerlines intersect at a single intersection located in front of the member. It is about that.

[0008] In this cleaning device, at least one diffusion spray unit is provided in the first portion where the reference line is inclined toward the cleaning liquid supply pipe relative to the reference surface. Therefore, in the normal operating state where the cleaning device is suspended from the upper wall of the container body, the cleaning liquid sprayed from the pair of first spray holes of the diffusion spray unit provided in the first portion is diffused, allowing for efficient cleaning of a wide area of ​​the lower surface of the upper wall. Consequently, the number of spray holes can be reduced compared to the conventional technology (Patent Document 1) in which the cleaning liquid is sprayed linearly from all spray holes, thereby reducing design costs.

[0009] Furthermore, in this cleaning device, the diffusion spray unit provided in the first section is located near the upper wall of the container body under normal use conditions. Therefore, when cleaning the underside of the upper wall, the diffusion spray unit does not need to reach far with the cleaning solution, and the inner diameter of the first spray hole can be reduced, thereby reducing the amount of cleaning solution consumed.

[0010] Another feature of the cleaning apparatus according to the present invention is that the wall portion has at least one of a second portion in which the reference line is parallel to the reference plane and a third portion in which the reference line is inclined with respect to the reference plane on the side opposite to the cleaning fluid supply pipe, and at least one of the linear spray portion is provided in at least one of the second portion and the third portion.

[0011] In this cleaning device, at least one linear spray nozzle is provided in at least one of the second and third parts, so that cleaning areas located in a different direction from the cleaning area cleaned by the diffusion spray nozzle can be cleaned by the linear spray nozzle. In addition, since the linear spray nozzle can deliver the cleaning liquid to a greater distance than the diffusion spray nozzle, cleaning areas located at a greater distance can be cleaned efficiently.

[0012] Another feature of the cleaning apparatus according to the present invention is that the inner diameter of the second injection hole is set to be larger than the inner diameter of the first injection hole.

[0013] In this cleaning device, the inner diameter of the second injection hole in the linear injection section is set to be large, making it easier to deliver the cleaning liquid sprayed from the second injection hole to a greater distance. In the normal operating state, where the cleaning device is suspended from the upper wall of the container body, the diffusion injection section does not need to deliver the cleaning liquid to a greater distance, and the inner diameter of the first injection hole can be reduced to suppress the consumption of cleaning liquid. Therefore, even if the inner diameter of the second injection hole is set to be large, the overall consumption of cleaning liquid in the diffusion injection section and the linear injection section can be reduced, and a wide area of ​​the component can be efficiently cleaned with less cleaning liquid.

[0014] Another feature of the cleaning apparatus according to the present invention is that the first part is formed around a virtual straight line extending parallel to the centerline of the cleaning liquid supply pipe, and a plurality of the diffusion spray units are provided on the first part at intervals in the circumferential direction.

[0015] This cleaning device can efficiently clean a wide area of ​​a component using multiple diffusion spray nozzles.

[0016] To achieve the above objective, the container according to the present invention is characterized by comprising a container body having a peripheral wall portion, a lower wall portion, and an upper wall portion that constitute a storage space for accommodating an object, and the above-mentioned cleaning device, wherein the cleaning device body and the cleaning liquid supply pipe are arranged in the storage space, and the cleaning liquid supply pipe is fixed to the container body so as to hang down from the lower surface of the upper wall portion.

[0017] In this container, the cleaning liquid sprayed from a pair of first spray holes in the diffusion spray section provided in the first part is diffused, allowing for efficient cleaning of a wide area of ​​the lower surface of the upper wall. Therefore, compared to conventional technology (Patent Document 1) in which the cleaning liquid is sprayed linearly from all spray holes, the number of spray holes can be reduced, thereby lowering design costs.

[0018] Furthermore, in this container, the diffusion spray section located in the first part is positioned close to the upper wall. Therefore, when cleaning the underside of the upper wall, the diffusion spray section does not need to reach far, and the inner diameter of the first spray hole can be reduced, thereby reducing the amount of cleaning solution consumed.

[0019] Another feature of the container according to the present invention is that the container comprises a vertically elongated longitudinal member arranged in the containment space, and at least one of the diffusion spray units is configured to diffuse and spray the cleaning liquid toward the upper end of the portion of the cleaning liquid supply pipe located below the lower surface of the upper wall or toward the longitudinal member.

[0020] In this container, the upper end or longitudinal member of the portion of the cleaning solution supply pipe located below the lower surface of the upper wall can be efficiently cleaned with the diffused cleaning solution.

[0021] Another feature of the container according to the present invention is that it comprises at least two cleaning devices arranged in the containment space, wherein the cleaning liquid sprayed by at least one of the at least one of the diffusion spray section and at least one of the linear spray section of at least one of the other cleaning devices is directed onto at least one of the cleaning device body and the cleaning liquid supply pipe of at least one other cleaning device.

[0022] In this container, any one washing device can clean at least one other washing device.

[0023] Another feature of the container according to the present invention is that it includes a pipeline provided to extend outward from the upper wall portion. The pipeline has a main pipe having an internal space communicating with the accommodation space, and a branch pipe provided to branch from the pipe wall of the main pipe and to be positioned higher as it moves away from the main pipe. The cleaning liquid supply pipe is arranged to extend in the length direction of the main pipe within the internal space of the main pipe. The cleaning liquid supply pipe is provided with at least one diffusion injection portion for the branch pipe that diffuses and injects the cleaning liquid toward the inner surface of the branch pipe. The diffusion injection portion for the branch pipe has a pair of third injection holes formed in the pipe wall of the cleaning liquid supply pipe so as to inject the cleaning liquid linearly and to cause the injected cleaning liquids to collide with each other and diffuse.

[0024] In this container, the inner surface of the branch pipe can be efficiently cleaned with the diffused cleaning liquid. Further, since the branch pipe is provided to be positioned higher as it moves away from the main pipe, the cleaning liquid that has cleaned the inner surface of the branch pipe can be discharged by gravity into the internal space of the main pipe.

[0025] To achieve the above object, a cleaning method for a container according to the present invention includes a container body having a peripheral wall portion, a lower wall portion, and an upper wall portion that constitute an accommodation space for accommodating an object. The lower surface of the upper wall portion is curved so that the height gradually decreases from the central portion toward the peripheral portion. A cleaning method for a container for cleaning the container, the cleaning method including a cleaning device main body having a wall portion that constitutes a pressure chamber, and at least one diffusion injection portion having a pair of first injection holes formed in the wall portion so as to inject the cleaning liquid linearly ruyo and at least one linear injection portion having a second injection hole formed in the wall portion so as to inject the cleaning liquid linearly. circular Prepare a cleaning device, and when a virtual plane passing through the center of the upper wall portion in plan view and perpendicular to the horizontal plane is used as a dividing plane, and the accommodation space is divided into two spaces obtained by bisecting with the dividing plane and the two spaces are defined as a first space and a second space, arrange the cleaning device main body at the central portion in the direction in which the dividing plane extends in plan view in the first space, and inject the lower surface of the upper wall portion exposed in the first space from the pair of first injection holes of at least one of the diffusion injection portions circular The pair of first injection holes are formed such that their centerlines intersect at a single intersection. By causing a collision at the intersection located in the aforementioned accommodation spaceWash with the diffused cleaning liquid, and wash the lower surface of the upper wall portion exposed in the second space with the cleaning liquid jetted from the second jet holes of at least one of the linear jet portions.

[0026] In this method for cleaning the container, the lower surface of the upper wall portion exposed in the first space is washed with the cleaning liquid jetted and diffused from the pair of first jet holes of at least one diffusion jet portion. At this time, the cleaning liquid can be adhered to a wide range of the lower surface of the upper wall portion exposed in the first space, and a part of this cleaning liquid can be naturally caused to flow downward in a direction toward the front side from the dividing surface as viewed from the cleaning device. Therefore, the amount of the cleaning liquid jetted from the first jet holes may be small. A part of the cleaning liquid applied to the lower surface of the upper wall portion exposed in the first space may also flow to the lower surface of the upper wall portion exposed in the second space by the momentum of the jet. In such a case, a wider range can be cleaned.

[0027] Also, in this method for cleaning the container, the cleaning device washes the lower surface of the upper wall portion exposed in the second space with the cleaning liquid jetted from the second jet holes of at least one linear jet portion. At this time, in order to clean a wide range of the lower surface of the upper wall portion exposed in the second space, it is necessary to cause the cleaning liquid adhering to the inner surface to flow downward in a direction toward the back side from the dividing surface as viewed from the cleaning device. However, since the momentum of the cleaning liquid jetted linearly from the second jet holes is strong, it is easy to cause the cleaning liquid to flow downward to the back side. Therefore, the entire lower surface of the upper wall portion can be efficiently cleaned with a small amount of cleaning liquid.

[0029] Hereinafter, a cleaning apparatus, a container, and a method for cleaning a container according to embodiments of the present invention will be described with reference to the drawings.

[0030] (Container configuration according to the first embodiment) Figure 1 is a cross-sectional view showing the configuration of a container 10 (including a washing device 12) according to the first embodiment. Figure 2 is a diagram showing the configuration of the main part of the container 10, where Figure 2(A) is a partial cross-sectional view and Figure 2(B) is a cross-sectional view taken along line IIB-IIB in Figure 2(A).

[0031] The container 10 shown in Figure 1 is a reaction vessel used for processing raw materials and other substances in chemical plants, and comprises a container body 14, a jacket 16, a stirring blade 18, a rotary drive unit 20, and a washing device 12. The container 10 of the present invention is not limited to a reaction vessel, but may also be configured as a filtration device or a drying device (not shown), or as a filtration and drying device (Figure 13(A)).

[0032] The container body 14 shown in Figure 1 is a component that constitutes a storage space S for accommodating an object, and has a cylindrical peripheral wall portion 14a, a lower wall portion 14b formed to close the lower opening of the peripheral wall portion 14a, and an upper wall portion 14c formed to close the upper opening of the peripheral wall portion 14a. Each of the peripheral wall portion 14a, the lower wall portion 14b, and the upper wall portion 14c has a base material (not shown) made of a metal such as low carbon steel and low carbon stainless steel, and a glass lining layer (not shown) is formed on the inner surface of the base material.

[0033] The lower wall portion 14b includes a lower end plate 22 and a discharge nozzle 24 provided in the center of the lower end plate 22. In other words, the lower wall portion 14b includes all parts that are exposed to the storage space S at the bottom of the container body 14.

[0034] The lower end plate 22 is formed in a dish shape that curves downwards. The discharge nozzle 24 is a cylindrical part for discharging objects contained in the containment space S, and is formed to protrude downwards from the lower surface of the lower wall portion 14b. An on / off valve 26 is attached to the discharge nozzle 24.

[0035] The upper wall portion 14c includes an upper end plate 28, a stirring blade nozzle 30 provided in the center of the upper end plate 28, and a manhole nozzle 32 and a cleaning device nozzle 34 provided at intervals from each other on the outer circumference of the upper end plate 28. The upper wall portion 14c also includes a stirring blade cover 36 attached to the stirring blade nozzle 30 and a manhole cover 38 attached to the manhole nozzle 32. In other words, the upper wall portion 14c includes all parts exposed to the storage space S at the top of the container body 14.

[0036] The upper end plate 28 is formed in a dish shape that curves upward and bulges outwards. Therefore, the lower surface of the upper wall portion 14c is curved so that its height gradually decreases from the center to the periphery. The stirring blade nozzle 30 is a cylindrical portion for inserting the stirring blade 18 into the housing space S, and is formed to protrude upward from the upper surface of the upper end plate 28.

[0037] The stirring blade cover 36 is a part that closes the opening of the stirring blade nozzle 30 and supports the stirring blade 18, and is detachably attached to the upper end of the stirring blade nozzle 30 via a sealing material 40. A through hole 36a is formed in the center of the stirring blade cover 36 through which the rotation shaft 18a of the stirring blade 18 is inserted. A support part 42 is provided on the upper part of the stirring blade cover 36 for rotatably supporting the stirring blade 18.

[0038] The manhole nozzle 32 is a cylindrical part that has functions such as an entrance for workers to enter and exit when inspecting the containment space S, an input port for putting objects into the containment space S, and a window frame for attaching a viewing window (not shown), and is formed to protrude diagonally upward from the upper surface of the upper end plate 28.

[0039] The manhole cover 38 is the part that closes the opening of the manhole nozzle 32, and is detachably attached to the upper end of the manhole nozzle 32 via a sealing material 44.

[0040] The cleaning device nozzle 34 is a cylindrical portion for inserting the cleaning device 12 into the housing space S, and is formed to protrude upward from the upper surface of the upper end plate 28. A flange 34a is provided on the outer circumference of the upper end of the cleaning device nozzle 34.

[0041] The jacket 16 shown in Figure 1 is a component for heating the container body 14 with the heat of a heat transfer medium, and has a jacket body 16a formed to conform to the outer surfaces of the peripheral wall portion 14a and the lower wall portion 14b. Between the outer surfaces of the peripheral wall portion 14a and the lower wall portion 14b and the inner surface of the jacket body 16a, a heat transfer medium channel 16b is formed for the circulation of a heat transfer medium such as steam or hot water. When the heat transfer medium flows through the heat transfer medium channel 16b, the container body 14 is heated by the heat of the heat transfer medium, and consequently, the object contained in the containment space S is heated.

[0042] The stirring blade 18 shown in Figure 1 has a rod-shaped rotating shaft 18a and a blade member 18b provided at the lower end of the rotating shaft 18a. The lower end of the rotating shaft 18a and the blade member 18b are located at the bottom of the housing space S. The upper end of the rotating shaft 18a protrudes upward from the upper surface of the stirring blade cover 36, and this protruding portion is rotatably supported by the support part 42.

[0043] The rotary drive unit 20 is a power device for applying rotational force to the stirring blade 18, and has a motor 20a and a drive shaft 20b that is rotated by the motor 20a. The motor 20a is attached to the stirring blade cover 36 via a frame 46. The drive shaft 20b is connected to the rotation shaft 18a of the stirring blade 18. When the drive shaft 20b is rotated by the motor 20a, the rotation shaft 18a and the blade member 18b are rotated, and the object contained in the containment space S is stirred.

[0044] The cleaning device 12 shown in Figure 1 is configured to clean the inner surface of the container body 14, which is a "component," with the cleaning solution K. The type of cleaning solution K is not particularly limited; water may be used, or a solution in which a solute is dissolved in a solvent may be used. A dispersion containing suspended solids may also be used. Furthermore, water, solutions, and dispersions containing air bubbles may also be used.

[0045] As shown in Figure 2(B), when a virtual plane passing through the center point M of the upper wall portion 14c and perpendicular to the horizontal plane in both bottom and top views is defined as the dividing plane N, and the two spaces obtained by dividing the storage space S by the dividing plane N are defined as the first space S1 and the second space S2, the cleaning nozzle 34 and the cleaning device 12 are positioned in the center of the first space S1 in the direction in which the dividing plane N extends, as seen in both bottom and top views.

[0046] The positions of the cleaning nozzle 34 and the cleaning device 12 in the direction perpendicular to the direction in which the dividing surface N extends, as seen from the bottom and in the top view, are not particularly limited, but in order to efficiently clean the lower surface of the upper wall portion 14c, it is desirable that they be in a position close to the peripheral wall portion 14a.

[0047] Figure 3 is a cross-sectional view showing the configuration of the cleaning device 12. Figure 4 is a diagram showing the configuration of the cleaning device body 50, where Figure 4(A) is a perspective view and Figure 4(B) is a front view. Figure 5 is a diagram showing the configuration of the cleaning device body 50, where Figure 5(A) is a cross-sectional view along the line VA-VA in Figure 4(B), and Figure 5(B) is a cross-sectional view along the line VB-VB in Figure 4(B). Figure 6 is a plan view showing the configuration of the cleaning device body 50. Figure 7(A) is a cross-sectional view showing the configuration of the diffusion spray unit 54, and Figure 7(B) is a longitudinal cross-sectional view showing the configuration of the diffusion spray unit 54. Figure 8 is a table showing the results of the cleaning test.

[0048] As shown in Figure 3, the cleaning device 12 comprises a cleaning device body 50 arranged in a containment space S (Figures 2(A), (B)), a cleaning liquid supply port 52 provided on the cleaning device body 50, at least one (eight in this embodiment) diffusion spray section 54 provided on the cleaning device body 50, at least one (eight in this embodiment) linear spray section 56 provided on the cleaning device body 50, a straight tubular cleaning liquid supply pipe 58 connected to the cleaning liquid supply port 52, and at least one (16 in this embodiment) linear spray section 60 provided on the cleaning liquid supply pipe 58.

[0049] The maximum outer diameter of the cleaning device body 50 is set to be smaller than the inner diameter of the cleaning device nozzle 34 (Figure 1). Therefore, users of the cleaning device 12 can insert the cleaning device 12 into the housing space S from the cleaning device nozzle 34. In the following description, the end of each part of the cleaning device 12 in the insertion direction will be referred to as the "tip," and the end in the opposite direction will be referred to as the "base."

[0050] The cleaning device body 50 shown in Figure 3 is a hollow member having a pressure chamber T. In other words, the cleaning device body 50 has a wall portion 62 that constitutes the pressure chamber T. As shown in Figures 4(A) and (B), the wall portion 62 has a small-diameter cylindrical portion 62a, a flaring portion 62b, a large-diameter cylindrical portion 62c, and a tapering portion 62d that are continuous from the base end to the tip of the cleaning device body 50.

[0051] The small-diameter cylindrical portion 62a is formed in the shape of a straight tube with a circular cross-section, and the large-diameter cylindrical portion 62c is formed in the shape of a straight tube with a larger circular cross-section than the small-diameter cylindrical portion 62a. The flared portion 62b is formed in the shape of a frustoconical cone that widens smoothly towards the tip without any steps. The tapered portion 62d is formed in the shape of a cone that tapers smoothly towards the tip without any steps. As shown in Figure 5(A), the thickness of each of these portions is constant.

[0052] The cleaning fluid supply port 52 shown in Figures 4(A) and 4(B) is an opening for supplying cleaning fluid K to the pressure chamber T, and is located at the base end of the cleaning device body 50, that is, at the base end of the small-diameter cylindrical portion 62a.

[0053] As shown in Figure 4(B), when a virtual straight line V is taken as the reference line from the outer surface of any part of the wall 62 outward in the thickness direction of the wall 62, and a virtual plane W is taken as the reference plane that is perpendicular to the center line U (Figure 3) of the cleaning fluid supply pipe 58 and includes the base point of the reference line V located on the outer surface, the wall 62 has a flared portion 62b, or "first portion," where the reference line V is inclined toward the cleaning fluid supply pipe 58 with respect to the reference plane W. The wall 62 also has a small-diameter cylindrical portion 62a and a large-diameter cylindrical portion 62c, or "second portion," where the reference line V is parallel to the reference plane W. Furthermore, the wall 62 has a tapered portion 62d, or "third portion," where the reference line V is inclined toward the opposite side of the cleaning fluid supply pipe 58 with respect to the reference plane W.

[0054] The diffusion spray section 54 shown in Figures 5(A) and 5(B) is the part that diffuses and sprays the cleaning liquid K (Figures 2(A) and 2(B)) from the pressure chamber T toward the inner surface of the container body 14, which is a "component". As shown in Figure 6, in this embodiment, a plurality (eight) of diffusion spray sections 54 are provided at 45-degree angular intervals in the circumferential direction on the flared section 62b, i.e., the "first section". In other words, the flared section 62b, i.e., the "first section", is formed around a virtual straight line extending parallel to the center line U (Figure 3) of the cleaning liquid supply pipe 58, and the plurality of diffusion spray sections 54 are provided at circumferential intervals on the flared section 62b, i.e., the "first section". When each of the plurality of diffusion spray sections 54 is viewed individually, they are configured in almost the same manner except for the spray direction.

[0055] As shown in Figure 7(A), the diffusion spray unit 54 has a pair of first spray holes 54a and 54b formed in the wall portion 62 to spray the cleaning liquid K in a straight line and to cause the sprayed cleaning liquid K to collide with each other and diffuse in a frustoconical shape. Each of the pair of first spray holes 54a and 54b is a simple circular hole formed to the same size. The inner diameter of the first spray holes 54a and 54b is not particularly limited, but in this embodiment it is set to 1.0 mm.

[0056] In this embodiment, the first injection holes 54a and 54b are formed at intervals in the circumferential direction of the flared portion 62b, or "first portion," such that their centerlines L1 and L2 are inclined toward the cleaning fluid supply pipe 58 (Figure 3) with respect to the reference plane W (Figure 7(B)), and their centerlines L1 and L2 intersect at a single intersection P.

[0057] Here, as shown in Figure 7(A), the first reference plane Q1 is defined as a virtual plane containing the centerlines L1 and L2 of the pair of first injection holes 54a and 54b, respectively, and the reference points G1 and G2 are defined as points where the centerlines L1 and L2 of the pair of first injection holes 54a and 54b intersect with the virtual outer surface of the wall portion 62 assuming that the first injection holes 54a and 54b are not formed. Furthermore, as shown in Figure 7(B), the second reference plane Q2 is defined as a virtual plane extending in the thickness direction of the wall portion 62, including the two reference points G1 and G2. In addition, as shown in Figure 7(A), the reference line E is defined as a virtual straight line that bisects the angle formed by the centerlines L1 and L2 of the pair of first injection holes 54a and 54b on the first reference plane Q1.

[0058] With this definition, in this embodiment, in the flared portion 62b (first portion), the inclination angle of the second reference surface Q2 with respect to the reference surface W is set to 30 degrees, and the inclination angle of the first reference surface Q1 with respect to the second reference surface Q2 is set to 30 degrees. The angle at which the centerlines L1 and L2 of the first injection holes 54a and 54b intersect at intersection P is set to 60 degrees. Furthermore, the reference line E is arranged to extend in the thickness direction of the wall portion 62 in the first reference surface Q1.

[0059] The inclination angle of the second reference surface Q2 with respect to the reference surface W, the inclination angle of the first reference surface Q1 with respect to the second reference surface Q2, and the angle at which the centerlines L1 and L2 intersect at intersection P are not limited to this embodiment and may be changed as appropriate. For example, in the flared portion 62b (first portion), the inclination angle of the second reference surface Q2 with respect to the reference surface W may be set in the range of 10 to 90 degrees or in the range of 20 to 70 degrees. Also, the inclination angle of the first reference surface Q1 with respect to the second reference surface Q2 may be set in the range of 0 to 60 degrees or in the range of 15 to 45 degrees. Furthermore, the angle at which the centerlines L1 and L2 intersect at intersection P may be set in the range of 30 to 120 degrees or in the range of 45 to 90 degrees. As the inclination angle of the first reference surface Q1 with respect to the second reference surface Q2 increases, the length of the first spray holes 54a and 54b increases, and the spray state of the cleaning liquid K becomes more stable.

[0060] Furthermore, the direction in which the reference line E extends may be a direction that intersects with the thickness direction of the wall portion 62 on the first reference surface Q1. In addition, the sizes of the pair of first injection holes 54a and 54b do not necessarily have to be the same, and the direction in which the cleaning liquid K diffused by the collision is directed may be appropriately changed by making their sizes different.

[0061] As shown in Figure 3, when the portion of the cleaning fluid supply pipe 58 located below the lower surface of the upper wall portion 14c is defined as the "hanging portion 64", the direction in which the reference line E extends is offset from the direction from the diffusion spray portion 54 toward the upper end portion 64a of the hanging portion 64. However, the cleaning fluid K sprayed from the pair of first spray holes 54a and 54b of the diffusion spray portion 54 spreads out in a frustoconical shape by colliding with each other, so that the cleaning fluid K can be diffused and sprayed toward the upper end portion 64a of the hanging portion 64. In other words, the diffusion spray portion 54 is configured to diffuse and spray the cleaning fluid K toward the upper end portion 64a of the hanging portion 64.

[0062] The linear injection section 56 shown in Figures 5(A) and 5(B) is the part that linearly injects the cleaning fluid K (Figures 2(A) and 2(B)) from the pressure chamber T toward the inner surface of the container body 14, which is a "component". In this embodiment, a plurality (eight) of linear injection sections 56 are provided in the large-diameter cylindrical section 62c, i.e., the "second section," at 45-degree angular intervals in the circumferential direction. When each of the plurality of linear injection sections 56 is viewed individually, they are configured in substantially the same manner except for the injection direction.

[0063] The linear spray section 56 has a second spray hole 56a formed in the wall section 62 to spray the cleaning liquid K in a straight line. The second spray hole 56a is a simple circular hole. The inner diameter of the second spray hole 56a is not particularly limited, but it is desirable that it be larger than the inner diameter of the first spray holes 54a and 54b of the diffusion spray section 54, and in this embodiment, it is set to 1.2 mm. The inclination angle of the second spray hole 56a with respect to the reference plane W is not particularly limited, but it is desirable that it be set within the range of -60 to 60 degrees, and in this embodiment, it is set to 20 degrees. When multiple linear spray sections 56 are provided, the inclination angles of the second spray holes 56a of each linear spray section 56 with respect to the reference plane W may be the same or different. For example, the inclination angles of the second spray holes 56a with respect to the reference plane W of two adjacent linear spray sections 56 may be different.

[0064] As shown in Figure 2(B), in this embodiment, all diffusion spray units 54 are configured to spray cleaning liquid K onto the lower surface of the upper wall portion 14c exposed to the first space S1, and two linear spray units 56 are configured to spray cleaning liquid K onto the lower surface of the upper wall portion 14c exposed to the second space S2. In addition, one linear spray unit 56 is configured to spray cleaning liquid K onto the rotation axis 18a of the stirring blade 18. Therefore, the entire lower surface of the upper wall portion 14c and the rotation axis 18a of the stirring blade 18 can be cleaned with cleaning liquid K. The rotation axis 18a of the stirring blade 18 is a vertically elongated member located in the housing space S.

[0065] As shown in Figure 8, the inventors conducted cleaning tests to confirm the cleaning effect when the cleaning liquid K was sprayed in a diffuse manner using the diffusion spray unit 54 and when the cleaning liquid K was sprayed linearly using the linear spray unit 56. The test conditions were a spray pressure of "0.3 MPa" and a cleaning time of "30 seconds". The angle at which the centerlines L1 and L2 of the first spray holes 54a and 54b of the diffusion spray unit 54 intersect was set to "90 degrees", and the inclination angle of the first reference plane Q1 with respect to the second reference plane Q2 was set to "0 degrees". Furthermore, an acrylic plate placed at a distance of 800 mm from either the diffusion spray unit 54 or the linear spray unit 56 was used as the cleaning target. Water was then sprayed from either the diffusion spray unit 54 or the linear spray unit 56 toward the acrylic plate coated with water-based paint, and the area where the water-based paint had been removed was confirmed.

[0066] The results of the cleaning tests are shown in the table in Figure 8. In short, with diffusion spray, although the maximum distance the spray reaches is shorter compared to linear spray, it was confirmed that a wide cleaning area can be cleaned even when the nozzle diameter is reduced and the flow rate is decreased. On the other hand, with linear spray, although the cleaning range is narrower compared to diffusion spray, it was confirmed that distant components can be cleaned even when the nozzle diameter is reduced and the flow rate is decreased. In other words, it was confirmed that the force of the sprayed cleaning liquid is stronger with linear spray compared to diffusion spray.

[0067] The cleaning fluid supply pipe 58 shown in Figure 3 is a straight tubular member for supporting the cleaning device body 50 in the housing space S. A socket 58a is formed at the tip of the cleaning fluid supply pipe 58, and the cleaning fluid supply port 52 of the cleaning device body 50 is connected to the socket 58a by welding or a screw structure. A first flange 66 and a second flange 68 are formed at the base end of the cleaning fluid supply pipe 58.

[0068] As shown in Figure 2(A), the cleaning device body 50 and the cleaning fluid supply pipe 58 are arranged in the housing space S, and the first flange 66 of the cleaning fluid supply pipe 58 is connected to the flange 34a of the cleaning device nozzle 34 using the first clamp 70. In other words, the cleaning fluid supply pipe 58 is fixed to the container body 14 so as to hang down from the lower surface of the upper wall portion 14c. The second flange 68 is connected to the flange 76 of the cleaning fluid supply hose 74 extending from the cleaning fluid supply source (not shown) using the second clamp 72.

[0069] (How to clean the container) In Figures 1 and 2, the cleaning liquid K sprayed from the diffusion spray section 54 is shown as a dotted pattern, and the cleaning liquid K sprayed from the linear spray section 56 is shown as a dotted arrow. In addition, the cleaning liquid K flowing along the lower surface of the upper wall section 14c is shown as a thick arrow.

[0070] When cleaning the upper wall portion 14c of the container body 14 as a "component" using the cleaning device 12 shown in Figure 3, the operator first opens the on / off valve 26 shown in Figure 1 to discharge the object contained in the containment space S to the outside through the discharge nozzle 24. Next, the operator operates the pump of the cleaning fluid supply source (not shown) connected to the cleaning fluid supply hose 74 to supply the cleaning fluid K from the cleaning fluid supply pipe 58 of the cleaning device 12 to the pressure chamber T. The cleaning fluid K, pressurized in the pressure chamber T, is then sprayed from a pair of first spray holes 54a, 54b of each diffusion spray unit 54. The cleaning fluid K sprayed from a pair of first spray holes 54a, 54b of at least one (eight in this embodiment) diffusion spray unit 54 collides with each other and diffuses before being applied to the lower surface of the upper wall portion 14c exposed to the first space S1. Furthermore, the cleaning fluid K pressurized in the pressure chamber T is injected from the second injection holes 56a of each linear injection unit 56, and the cleaning fluid K injected from the second injection holes 56a of at least one (two in this embodiment) linear injection unit 56 is applied to the lower surface of the upper wall portion 14c exposed to the second space S2.

[0071] In other words, the cleaning device 12 cleans the lower surface of the upper wall portion 14c exposed to the first space S1 with cleaning liquid K that has been sprayed and diffused from a pair of first spray holes 54a and 54b of at least one (eight in this embodiment) diffusion spray section 54. The cleaning device 12 also cleans the lower surface of the upper wall portion 14c exposed to the second space S2 with cleaning liquid K sprayed from the second spray hole 56a of at least one (two in this embodiment) linear spray section 56.

[0072] In this container cleaning method, the cleaning liquid K can be applied to a wide area of ​​the lower surface of the upper wall portion 14c exposed in the first space S1, and a portion of this cleaning liquid K can be naturally allowed to flow down from the dividing surface N toward the front when viewed from the cleaning device 12. Therefore, the amount of cleaning liquid K sprayed from the pair of first spray holes 54a and 54b of the diffusion spray unit 54 can be small. A portion of the cleaning liquid K that hits the lower surface of the upper wall portion 14c exposed in the first space S1 also flows to the lower surface of the upper wall portion 14c exposed in the second space S2 due to the force of the spray, so a wide area can be cleaned. In addition, since the force of the cleaning liquid K sprayed linearly from the second spray hole 56a of the linear spray unit 56 is strong, the cleaning liquid K can easily flow down toward the back when viewed from the cleaning device 12. Therefore, the entire lower surface of the upper wall portion 14c can be efficiently cleaned with a small amount of cleaning liquid K.

[0073] (Effects of the first embodiment) According to the container 10 and cleaning device 12 of the first embodiment, the above configuration can achieve the following effects. Specifically, since at least one diffusion spray unit 54 is provided in the flared portion 62b (first portion) where the reference line V is inclined toward the cleaning liquid supply pipe 58 with respect to the reference surface W, in the normal operating state in which the cleaning device 12 is suspended from the upper wall portion 14c of the container body 14, the cleaning liquid K sprayed from the pair of first spray holes 54a, 54b of the diffusion spray unit 54 provided in the flared portion 62b (first portion) is diffused, and a wide area of ​​the lower surface of the upper wall portion 14c can be efficiently cleaned. Furthermore, as shown in the "Cleaning Test Results" in Figure 8, the cleaning range by the cleaning liquid diffused and sprayed from the diffusion spray unit 54 is significantly wider than the cleaning range by the cleaning liquid linearly sprayed from the linear spray unit 56, so that a wide area of ​​members other than the lower surface of the upper wall portion 14c can also be efficiently cleaned by the diffused and sprayed cleaning liquid.

[0074] Therefore, compared to a cleaning device that sprays cleaning fluid linearly from all nozzles, it is possible to reduce the number of nozzles, thereby lowering design costs and reducing the amount of cleaning fluid consumed. In addition, since the cleaning fluid K sprayed from the diffusion spray unit 54 spreads evenly over a wide area, uneven cleaning is less likely to occur compared to cleaning with only linearly sprayed cleaning fluid K, and cleaning can be completed in a shorter time.

[0075] Furthermore, since the diffusion spray section 54 provided in the flared section 62b (first section) is located near the upper wall section 14c, when cleaning the lower surface of the upper wall section 14c, the diffusion spray section 54 does not need to reach far, and the inner diameter of the first spray holes 54a and 54b can be reduced to suppress the consumption of cleaning liquid K. Therefore, even if the inner diameter of the second spray hole 56a is increased to allow the cleaning liquid K to reach far in the linear spray section 56, the overall consumption of cleaning liquid K by the diffusion spray section 54 and the linear spray section 56 can be reduced, and a wide area of ​​the material can be efficiently cleaned with less cleaning liquid K.

[0076] Since at least one linear spray section 56 is provided on at least one of the large-diameter cylindrical section 62c (second section) and the tapered section 62d (third section), the linear spray section 56 can clean cleaning areas located in a different direction from the cleaning area cleaned by the diffusion spray section 54. In addition, the linear spray section 56 can deliver the cleaning liquid K to a greater distance than the diffusion spray section 54, so cleaning areas located at a greater distance can be cleaned efficiently.

[0077] Since the inner diameter of the second injection hole 56a of the linear injection section 56 is set to be larger than the inner diameters of the first injection holes 54a and 54b of the diffusion injection section 54, the cleaning liquid K injected from the second injection hole 56a can be easily delivered over a long distance.

[0078] The flared portion 62b (first portion) is formed around a virtual straight line extending parallel to the center line U of the cleaning fluid supply pipe 58, and multiple diffusion spray units 54 are provided on the flared portion 62b (first portion) at intervals in the circumferential direction, so that a wide area of ​​the member can be efficiently cleaned by the multiple diffusion spray units 54.

[0079] At least one diffusion spray unit 54 is configured to diffuse and spray the cleaning liquid K toward the portion of the cleaning liquid supply pipe 58 located below the lower surface of the upper wall portion 14c, i.e., toward the upper end portion 64a of the hanging portion 64. Therefore, the upper end portion 64a of the hanging portion 64, where foreign matter tends to remain, can be efficiently cleaned with the diffused cleaning liquid K.

[0080] (modified version) In carrying out the present invention, the invention is not limited to the above embodiments, and various modifications are possible as long as they do not depart from the object of the present invention. For example, in the above embodiments, a plurality (8) of diffusion spray units 54 are provided in the flared section 62b (first section), but the number and arrangement of the diffusion spray units 54 provided in the flared section 62b (first section) are not particularly limited and may be changed as appropriate, as long as there is at least one. For example, 2 to 8 diffusion spray units 54 may be arranged at equal intervals in the flared section 62b (first section), or they may be arranged at different intervals depending on the area and orientation of the cleaning area to be cleaned. In addition, at least one diffusion spray unit 54 may be provided in at least one of the small-diameter cylindrical section 62a (second section), the large-diameter cylindrical section 62c (second section), and the tapered section 62d (third section), or it may be provided in the cleaning liquid supply pipe 58.

[0081] In the above embodiment, a plurality (16) of linear injection units 60 are provided in the cleaning fluid supply pipe 58. However, the number and arrangement of the linear injection units 60 provided in the cleaning fluid supply pipe 58 are not particularly limited and may be changed as appropriate, as long as there is at least one.

[0082] In the above embodiment, the container 10 is equipped with a stirring blade 18, but the stirring blade 18 may be omitted. In this case, the cleaning device 12 may be placed in the center of the containment space S. Also, if protrusions such as a pressure sensor and a temperature sensor (not shown) protrude from the lower surface of the upper wall portion 14c, the cleaning liquid K may be sprayed toward the protrusions from at least one of the diffusion spray portion 54 and the linear spray portion 56.

[0083] In the above embodiment, the inner diameters of the first injection holes 54a and 54b are set to 1.0 mm, and the inner diameter of the second injection hole is set to 1.2 mm. However, these inner diameters may be changed as appropriate, or they may be set to be the same.

[0084] (Modified version of the cleaning device body) Figure 9(A) is a perspective view showing the configuration of the cleaning device body 80 according to the first modified example, Figure 9(B) is a perspective view showing the configuration of the cleaning device body 81 according to the second modified example, Figure 9(C) is a perspective view showing the configuration of the cleaning device body 82 according to the third modified example, and Figure 9(D) is a perspective view showing the configuration of the cleaning device body 83 according to the fourth modified example. Figure 9(E) is a perspective view showing the configuration of the cleaning device body 84 according to the fifth modified example, and Figure 9(F) is a perspective view showing the configuration of the cleaning device body 86 according to the sixth modified example.

[0085] In the cleaning device body 50 shown in Figure 4(A), eight linear spray nozzles 56 are provided in the large-diameter cylindrical section 62c (second section). However, the number and arrangement of the linear spray nozzles 56 provided in the large-diameter cylindrical section 62c (second section) are not particularly limited and may be changed as appropriate, as long as there is at least one. In addition, at least one linear spray nozzle 56 may be provided in at least one of the small-diameter cylindrical section 62a (second section), the flared section 62b (first section), and the tapered section 62d (third section).

[0086] In the cleaning device body 80 according to the first modified example shown in Figure 9(A), three adjacent linear spray sections 56 out of the eight linear spray sections 56 are omitted. Note that the omitted parts are hidden and not visible in Figure 9(A). In addition, in the tapered section 62d (third section), two linear spray sections 56 are provided spaced apart from each other below the central linear spray section 56 among the five linear spray sections 56 provided in the flared section 62b (first section), in the direction in which the center line U (Figure 3) of the cleaning liquid supply pipe 58 extends when viewed from the front, i.e., in the axial direction of the cleaning device body 80.

[0087] In the cleaning device body 81 according to the second modified example shown in Figure 9(B), four linear jets 56 are added to the large-diameter cylindrical portion 62c (second portion) compared to the cleaning device body 80 according to the first modified example. Each of the four added linear jets 56 is positioned above the five linear jets 56, between two adjacent linear jets 56 of the five linear jets 56.

[0088] In the cleaning device body 50 shown in Figure 4(A), the pair of first injection holes 54a, 54b of the diffusion injection unit 54 are formed at a distance from each other in the circumferential direction in the flared portion 62b (first portion). However, as shown in the third modified example cleaning device body 82 in Figure 9(C), the pair of first injection holes 54a, 54b of at least one diffusion injection unit 54 may be formed at a distance from each other in the axial direction of the cleaning device body 82 when viewed from the front in the flared portion 62b (first portion). Furthermore, the pair of first injection holes 54a, 54b of at least one diffusion injection unit 54 and the second injection hole 56a of at least one linear injection unit 56 may be formed at a distance from each other in the axial direction of the cleaning device body 82 when viewed from the front. Furthermore, a pair of first injection holes 54a and 54b of at least one diffusion injection section 54 may be formed at least one of the small-diameter cylindrical section 62a (second section), the large-diameter cylindrical section 62c (second section), and the tapered section 62d (third section) at intervals in the axial direction of the cleaning device body 82 when viewed from the front.

[0089] The cleaning device body 50 shown in Figure 4(A) is formed to have a small diameter cylindrical portion 62a, a flaring portion 62b, a large diameter cylindrical portion 62c, and a tapered portion 62d. However, the shape of the cleaning device body 50 is not limited to this and may be changed as appropriate.

[0090] For example, the flared portion 62b may be formed in other shapes that flare towards the tip, such as a truncated pyramidal shape, a hemispherical shape, or a semi-ellipsoidal shape. Similarly, the tapered portion 62d may be formed in other shapes that tapere towards the tip, such as a pyramidal shape, a hemispherical shape, or a semi-ellipsoidal shape.

[0091] Furthermore, as shown in the fourth modified example, the cleaning device body 83 in Figure 9(D), the large-diameter cylindrical portion 62c may be omitted, and the flared portion 62b and the tapered portion 62d may be directly connected. In this modified example, four diffusion spray portions 54 are provided in the flared portion 62b (first portion). Also, as shown in the fifth modified example, the cleaning device body 84 in Figure 9(E), the portion excluding the small-diameter cylindrical portion 62a may be changed to a spherical portion 88a. Moreover, as shown in the sixth modified example, the cleaning device body 86 in Figure 9(F), the portion excluding the small-diameter cylindrical portion 62a may be changed to a rectangular parallelepiped or cubic portion 88b.

[0092] (Container according to the second embodiment) Figure 10 is a cross-sectional view showing the configuration of a container 90 according to the second embodiment. In addition to the container 10 shown in Figure 1, the container 90 according to the second embodiment includes a baffle 92 located in the containment space S. The baffle 92 is a vertically elongated member that causes a change in the flow of the material stirred by the stirring blade 18. At least one diffusion spray unit 54 provided in the cleaning device body 50 is configured to diffuse and spray the cleaning liquid K toward the baffle 92.

[0093] In this container 90, the baffle 92 can be efficiently cleaned with the cleaning liquid K sprayed and diffused from the diffusion spray unit 54. Note that the spray unit that sprays the cleaning liquid K toward the baffle 92 is not limited to the diffusion spray unit 54; at least one linear spray unit 56 may be used instead of the diffusion spray unit 54, or together with the diffusion spray unit 54.

[0094] (Container according to the third embodiment) Figure 11 is a partial cross-sectional view showing the configuration of a container 94 according to the third embodiment. The container 94 according to the third embodiment shown in Figure 11 includes, in addition to the container 10 shown in Figure 1, a conduit 96 extending outward from the upper wall portion 14c, and a cleaning device 98 is arranged to penetrate the conduit 96.

[0095] The pipeline 96 comprises a main pipe 100 extending vertically and branch pipes 102 branching off from the pipe wall 100a of the main pipe 100. The main pipe 100 is a straight tubular member having an internal space Z that communicates with the containment space S, and flanges 104a and 104b are provided at both ends of the main pipe 100. The lower flange 104a is connected to the flange 34a of the cleaning device nozzle 34, which constitutes the upper wall portion 14c, using a clamp 108. The cleaning device nozzle 34 and the main pipe 100 may be provided so as to extend in a direction intersecting the vertical direction.

[0096] The branch pipes 102 are positioned so that their position increases as they move away from the main pipe 100, and the end 102a of the branch pipe 102 furthest from the main pipe 100 is closed off by a cover 110. The cover 110 is equipped with devices 112 such as a pressure sensor and a temperature sensor. The number of branch pipes 102 is not particularly limited and may be two or more.

[0097] The cleaning device 98 comprises a cleaning device body 114 and a cleaning liquid supply pipe 116. The cleaning liquid supply pipe 116 is positioned in the internal space Z of the main pipe 100, extending in the longitudinal direction of the main pipe 100. A flange 118 provided on the cleaning liquid supply pipe 116 is connected to the upper flange 104b of the main pipe 100 using a clamp 120. The cleaning liquid supply pipe 116 is provided with at least one branch pipe diffusion spray section 121 that diffuses and sprays the cleaning liquid K toward the inner surface of the branch pipe 102. The branch pipe diffusion spray section 121 sprays the cleaning liquid K in a straight line and has a pair of third spray holes 121a, 121b formed on the wall of the cleaning liquid supply pipe 116 to cause the sprayed cleaning liquid K to collide with each other and diffuse.

[0098] In this container 90, the inner surface of the branch pipe 102 can be efficiently cleaned with the diffused cleaning solution K. Furthermore, since the branch pipe 102 is positioned so that its position increases as it moves away from the main pipe 100, as shown by the white arrows in Figure 11, the cleaning solution K that has cleaned the inner surface of the branch pipe 102 can be discharged by gravity into the internal space Z of the main pipe 100, and foreign matter adhering to the surface of the cleaning solution supply pipe 116 can be washed away with the cleaning solution K.

[0099] (Container according to the fourth embodiment) Figure 12 shows the configuration of a container 122 according to the fourth embodiment, where Figure 12(A) is a partial cross-sectional view and Figure 12(B) is a cross-sectional view taken along the line XIIB-XIIB in Figure 12(A). The container 122 according to the fourth embodiment shown in Figure 12 comprises at least two (two in this embodiment) cleaning devices 12 arranged in a containment space S. The cleaning liquid K sprayed by at least one of at least one diffusion spray section 54 and at least one linear spray section 56 of any one of the cleaning devices 12 is applied to at least one of the cleaning device body 50 and cleaning liquid supply pipe 58 of at least one (one in this embodiment) other cleaning device 12.

[0100] In this container 122, at least one other cleaning device 12 can be cleaned with any one of the cleaning devices 12.

[0101] (Container according to the fifth embodiment) Figure 13(A) is a cross-sectional view showing the configuration of the container 124 according to the fifth embodiment, and Figure 13(B) is a perspective view showing the configuration of the washing device 126 used in the container 124. The container 124 according to the fifth embodiment is configured as a filtration and drying device and comprises a container body 128, a jacket 130, a filtration section 132, a stirring device 134, a tilting drive section 136, and a washing device 126. The container body 128 has a peripheral wall section 128a, a lower wall section 128b, and an upper wall section 128c.

[0102] The lower wall portion 128b is detachably attached to the peripheral wall portion 128a so as to close the opening on the lower side of the peripheral wall portion 128a. Therefore, by removing the lower wall portion 128b, the opening on the lower side of the peripheral wall portion 128a can be opened, and even if the cleaning device 126 is large in size, the cleaning device 126 can be inserted into the housing space S through this opening.

[0103] The cleaning device 126 shown in Figure 13(B) comprises a hollow ring-shaped cleaning device body 138 having a circular cross-section and a cleaning fluid supply pipe 140. The outer diameter of the cleaning device body 138 is determined to be the size along the outer circumference of the lower surface of the upper wall portion 128c. In the cleaning device body 138, the portion located above a virtual plane (not shown) passing through the center of the circular cross-section is the "first portion," and the portion overlapping with this virtual plane is the "second portion." The portion located below this virtual plane is the "third portion."

[0104] Furthermore, multiple diffusion spray sections 54 are formed in the "first section," and at least one linear spray section 56 is formed in at least one of the "second section" or the "third section." The cleaning fluid supply pipe 140 is connected to the upper surface of the cleaning device body 138, and the center line U of the cleaning fluid supply pipe 140 is offset from the center line F of the cleaning device body 138. Therefore, the "first section" is formed around a virtual straight line, i.e., the center line F, that extends parallel to the center line U of the cleaning fluid supply pipe 140, and the multiple diffusion spray sections 54 are provided in the "first section" at intervals in the circumferential direction.

[0105] In this container 124, a wide area of ​​the lower surface of the upper wall portion 128c can be efficiently cleaned by the multiple diffusion spray nozzles 54 of the cleaning device 126.

[0106] Figure 14 is a perspective view showing the configuration of another cleaning device 142 used in the container 124 (Figure 13(A)) according to the fifth embodiment. In the cleaning device 126 shown in Figure 13(B), the cleaning device body 138 is formed in a ring shape, but as in the cleaning device 142 shown in Figure 14, the cleaning device body 144 may be formed in a C-shape or U-shape in a plan view.
