Description

Technical Field

[0001] The present invention relates to a cleaning device used for spraying a cleaning liquid onto a member for cleaning, a processing device including the cleaning device, and a pipeline.

Background Art

[0002] The spray nozzle (cleaning device) described in Patent Document 1 includes a cleaning nozzle disposed in the internal space of a tank (container) and a cleaning liquid supply pipe for supplying a cleaning liquid to the cleaning nozzle. When cleaning an object to be cleaned using this spray nozzle, the cleaning liquid is supplied from the cleaning liquid supply pipe to the cleaning nozzle. Then, the cleaning liquid is sprayed in a columnar shape from a plurality of cleaning liquid injection holes formed in the cleaning nozzle and applied to the object to be cleaned in a dot shape.

[0003] However, in the injection mode of applying the cleaning liquid to the object to be cleaned in a dot shape, that is, in the dot-shaped injection mode, there is a problem that it is difficult to efficiently clean the object to be cleaned because the degree of freedom in design is low. That is, in order to uniformly clean a wide range of the object to be cleaned in the dot-shaped injection mode, it is necessary to increase the number of cleaning liquid injection holes and finely adjust the injection direction of the cleaning liquid. In this case, however, the degree of freedom in designing the injection mode is greatly limited from the cost and technical aspects, and ultimately, the object to be cleaned could not be efficiently cleaned.

[0004] Patent Document 2 describes a spray nozzle having a pair of ejection holes for spraying a liquid in a fan shape. However, this spray nozzle is used for the purpose of spraying agricultural chemical water and has not been considered for the purpose of cleaning an object to be cleaned. Therefore, the shape and size of this spray nozzle are completely different from those of the cleaning nozzle of Patent Document 1, and it is not easy to combine this spray nozzle with the cleaning nozzle of Patent Document 1.

[0005] [Patent Document 1] Patent No. 4606208 [Patent Document 2] Japanese Utility Model Publication No. 49-143005 [Overview of the project]

[0006] The present invention was made to address the above-mentioned problems, and aims to provide a cleaning device, a processing device, and a pipeline that can efficiently clean components, which are the objects to be cleaned, by increasing the degree of freedom in the design regarding the spraying manner of the cleaning liquid.

[0007] To achieve the above objective, the cleaning apparatus according to the present invention is characterized by a cleaning apparatus for cleaning a component with a cleaning liquid, comprising: a cleaning apparatus body; a pressure chamber formed inside the cleaning apparatus body; a cleaning liquid supply port provided on the cleaning apparatus body to supply cleaning liquid to the pressure chamber; and at least one spraying part provided on the cleaning apparatus body to spray cleaning liquid toward the component, wherein the spraying part is formed on the wall portion of the cleaning apparatus body constituting the pressure chamber and a pair of spraying parts that connect the space outside the cleaning apparatus body to the pressure chamber. circular It has a spray hole, and the pair of spray holes are such that the cleaning liquid sprayed in a columnar shape from them collides with each other. In front of the aforementioned member The structure is formed so that these centerlines intersect at a single intersection, spreading out in a fan shape, and the portion of the wall in which the pair of injection holes are formed is formed to have a certain thickness and bulge toward the intersection.

[0008] In this cleaning device, the cleaning liquid is sprayed in a columnar shape from a pair of nozzles, colliding with each other and spreading out in a fan shape. By appropriately selecting the position, size, and orientation of each nozzle in the pair, the spray pattern of the cleaning liquid can be appropriately determined according to the position and shape of the material being cleaned. In other words, this cleaning device allows for greater design flexibility regarding the spray pattern of the cleaning liquid, enabling efficient cleaning of the material being cleaned. Furthermore, since each of the nozzles in the pair can be formed as a simple through-hole, the processing of the nozzles is easy, and the adhesion of foreign matter to the nozzles can be suppressed, thereby suppressing contamination.

[0009] In this cleaning device, the portion of the wall where the pair of injection holes are formed has a certain thickness and is formed to bulge toward the intersection. Compared to a case where this portion does not bulge toward the intersection, the length of each of the pair of injection holes can be increased. Therefore, the spray state (mainly the spray shape) of the cleaning liquid sprayed from each of the pair of injection holes can be stabilized, and the material can be cleaned efficiently.

[0010] Another feature of the cleaning apparatus according to the present invention is that when a virtual plane containing the centerlines of each of the pair of injection holes is defined as the first reference plane, and the point where the centerlines of each of the pair of injection holes intersect with the virtual outer surface of the wall portion assuming that the injection holes are not formed is defined as the reference point, and a virtual plane extending in the thickness direction of the wall portion including the two reference points is defined as the second reference plane, the first reference plane and the second reference plane intersect.

[0011] When the first and second reference planes coincide, the length of each of the pair of spray holes is minimized. In this cleaning device, since the first and second reference planes intersect, the length of each of the pair of spray holes can be increased compared to the case where the first and second reference planes coincide. Therefore, the spray state (mainly the spray shape) of the cleaning fluid sprayed from each of the pair of spray holes can be stabilized, and the material can be cleaned efficiently.

[0012] To achieve the above objective, the processing apparatus according to the present invention is characterized by comprising a container having a container body having a storage space for accommodating an object to be processed, and one of the aforementioned washing devices, wherein the washing device body of the washing device is arranged in the storage space.

[0013] Because this processing apparatus is equipped with the above-mentioned cleaning device, the degree of design freedom regarding the spray pattern of the cleaning liquid can be increased, and the components to be cleaned can be cleaned efficiently. In addition, the processing of the spray holes is easy, and the adhesion of foreign matter to the spray holes can be suppressed, thereby suppressing foreign matter contamination. Furthermore, the spray state (mainly the spray shape) of the cleaning liquid sprayed from each of the pair of spray holes can be stabilized, allowing for efficient cleaning of the components.

[0014] To achieve the above objective, the cleaning apparatus according to the present invention is characterized by a cleaning apparatus for cleaning a component with a cleaning liquid, comprising: a cleaning apparatus body; a pressure chamber formed inside the cleaning apparatus body; a cleaning liquid supply port provided on the cleaning apparatus body to supply cleaning liquid to the pressure chamber; and at least one spraying part provided on the cleaning apparatus body to spray cleaning liquid toward the component, wherein the spraying part is formed on the wall portion of the cleaning apparatus body constituting the pressure chamber and a pair of spraying parts that connect the space outside the cleaning apparatus body to the pressure chamber. circular It has a spray hole, and the pair of spray holes are such that the cleaning liquid sprayed in a columnar shape from them collides with each other. In front of the aforementioned member The structure is formed so that these centerlines spread out in a fan shape and intersect at a single intersection. The first reference plane is defined as a virtual plane containing the centerlines of each of the pair of injection holes, the second reference plane is defined as a virtual plane extending in the thickness direction of the wall portion, containing the two reference points, and the point where the centerlines of each of the pair of injection holes intersect with the virtual outer surface of the wall portion assuming that the injection holes are not formed. The first reference plane and the second reference plane intersect at this point.

[0015] In this cleaning device, the cleaning liquid is sprayed in a columnar shape from a pair of nozzles, colliding with each other and spreading out in a fan shape. By appropriately selecting the position, size, and orientation of each nozzle in the pair, the spray pattern of the cleaning liquid can be appropriately determined according to the position and shape of the material being cleaned. In other words, this cleaning device allows for greater design flexibility regarding the spray pattern of the cleaning liquid, enabling efficient cleaning of the material being cleaned. Furthermore, since each of the nozzles in the pair can be formed as a simple through-hole, the processing of the nozzles is easy, and the adhesion of foreign matter to the nozzles can be suppressed, thereby suppressing contamination.

[0016] In this cleaning device, the first and second reference surfaces intersect, allowing for longer lengths for each of the pair of spray holes compared to when they coincide. Therefore, the spray state (mainly the spray shape) of the cleaning fluid ejected from each of the pair of spray holes can be stabilized, enabling efficient cleaning of the components.

[0017] Another feature of the cleaning device according to the present invention is that it comprises a plurality of spraying units provided on the cleaning device body, and the first angle at which the first reference plane and the second reference plane intersect in one of the spraying units is determined to be different from the second angle at which the first reference plane and the second reference plane intersect in another of the spraying units.

[0018] This cleaning device allows for greater design flexibility regarding the spray pattern of the cleaning fluid for each of the multiple spray nozzles, enabling efficient cleaning of components. Furthermore, since the first angle in one spray nozzle is set to be different from the second angle in another spray nozzle, it is possible to direct the spray direction of the cleaning fluid in different directions from these nozzles, further increasing design flexibility.

[0019] To achieve the above objective, the processing apparatus according to the present invention is characterized by comprising a container having a container body having a storage space for accommodating an object to be processed, and one of the aforementioned washing devices, wherein the washing device body of the washing device is arranged in the storage space.

[0020] Because this processing apparatus is equipped with the above-mentioned cleaning device, the degree of design freedom regarding the spray pattern of the cleaning liquid can be increased, and the components to be cleaned can be cleaned efficiently. In addition, the processing of the spray holes is easy, and the adhesion of foreign matter to the spray holes can be suppressed, thereby suppressing foreign matter contamination. Furthermore, the spray state (mainly the spray shape) of the cleaning liquid sprayed from each of the pair of spray holes can be stabilized, allowing for efficient cleaning of the components.

[0021] To achieve the above objective, the pipeline according to the present invention is characterized by comprising a main pipe, branch pipes provided branching from the pipe wall of the main pipe, and a cleaning device for cleaning the inner surface of the branch pipe with a cleaning liquid, wherein the cleaning device comprises a tubular cleaning device body arranged inside the main pipe and extending in the longitudinal direction of the main pipe, a pressure chamber formed inside the cleaning device body, a cleaning liquid supply port provided on the cleaning device body to supply cleaning liquid to the pressure chamber, and a spraying part provided on the cleaning device body to spray cleaning liquid toward the inner surface of the branch pipe, wherein the spraying part is formed on the wall of the cleaning device body that constitutes the pressure chamber and a pair of spraying parts that connect the space outside the cleaning device body with the pressure chamber circular It has a spray hole, and the pair of spray holes are such that the cleaning liquid sprayed in a columnar shape from them collides with each other. In front of the inner surface of the aforementioned branch pipe The structure is formed so that these centerlines intersect at a single intersection, spreading out in a fan shape, and the portion of the wall in which the pair of injection holes are formed is formed to bulge toward the intersection with a certain thickness.

[0022] In this pipeline, the cleaning fluid sprayed in a columnar shape from a pair of injection holes collides with each other and spreads out in a fan shape. Therefore, by appropriately selecting the position, size, and orientation of each of the pair of injection holes, the spray pattern of the cleaning fluid can be appropriately determined according to the position and shape of the inner surface of the branch pipe. Furthermore, since each of the pair of injection holes can be formed as a simple through-hole, the processing of the injection holes is easy, and the adhesion of foreign matter to the injection holes can be suppressed, thereby suppressing foreign matter contamination.

[0023] In this pipeline, the portion of the wall where a pair of injection holes are formed has a certain thickness and is formed to bulge toward the intersection side. Therefore, compared with the case where this portion does not bulge toward the intersection side, the length of each of the pair of injection holes can be increased. Thus, the injection state (mainly the injection shape) of the cleaning liquid injected from each of the pair of injection holes can be stabilized, and the inner surface of the branch pipe can be efficiently cleaned.

[0024] Another feature of the pipeline according to the present invention is that the branch pipe is provided so that its position becomes higher as it moves away from the main pipe. Taking a virtual plane including the center line of each of the pair of injection holes as the first reference plane, and taking the point where the center line of each of the pair of injection holes intersects the virtual outer surface of the wall when it is assumed that the injection holes are not formed as the reference point, when a virtual plane that extends in the thickness direction of the wall and includes the two reference points is taken as the second reference plane, the first reference plane is inclined with respect to the second reference plane such that a part of the cleaning liquid that has spread in a fan shape hits the vertical upper part in the circumferential direction of the inner surface of the branch pipe.

[0025] In this pipeline, since the first reference plane is inclined with respect to the second reference plane such that a part of the cleaning liquid that has spread in a fan shape hits the vertical upper part in the circumferential direction of the inner surface of the branch pipe, compared with the case where the first reference plane is not inclined with respect to the second reference plane, the length of each of the pair of injection holes can be increased. Thus, the injection state (mainly the injection shape) of the cleaning liquid can be stabilized, and the member can be efficiently cleaned. Also, since it is easy to apply the cleaning liquid to the vertical upper part in the circumferential direction of the inner surface of the branch pipe, a wide range of the inner surface of the branch pipe can be efficiently cleaned using the cleaning liquid that flows down from the vertical upper part. Furthermore, since the branch pipe is provided so that its position becomes 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 into the main pipe by gravity.

[0026] To achieve the above objective, the pipeline according to the present invention is characterized by comprising a main pipe, branch pipes provided branching from the pipe wall of the main pipe, and a cleaning device for cleaning the inner surface of the branch pipe with a cleaning liquid, wherein the branch pipes are provided so that their position increases as they move away from the main pipe, and the cleaning device comprises a tubular cleaning device body arranged inside the main pipe and extending in the longitudinal direction of the main pipe, a pressure chamber formed inside the cleaning device body, a cleaning liquid supply port provided on the cleaning device body to supply cleaning liquid to the pressure chamber, and a spraying part provided on the cleaning device body to spray cleaning liquid toward the inner surface of the branch pipe, wherein the spraying part is formed on the wall portion of the cleaning device body that constitutes the pressure chamber and a pair of spraying parts that connect the space outside the cleaning device body with the pressure chamber circular It has a spray hole, and the pair of spray holes are such that the cleaning liquid sprayed in a columnar shape from them collides with each other. In front of the inner surface of the aforementioned branch pipe These centerlines are formed to spread out in a fan shape, with each centerline of the pair of injection holes being defined as the first reference plane, and the point where each centerline of the pair of injection holes intersects with the virtual outer surface of the wall portion assuming that the injection holes are not formed is defined as the reference point, and the virtual plane extending in the thickness direction of the wall portion, including the two reference points, is defined as the second reference plane. and In this configuration, the first reference plane is inclined with respect to the second reference plane so that a portion of the fan-shaped cleaning solution is directed onto the upper vertical portion of the inner surface of the branch pipe in the circumferential direction.

[0027] In this pipeline, the cleaning fluid sprayed in a columnar shape from a pair of injection holes collides with each other and spreads out in a fan shape. Therefore, by appropriately selecting the position, size, and orientation of each of the pair of injection holes, the spray pattern of the cleaning fluid can be appropriately determined according to the position and shape of the inner surface of the branch pipe. Furthermore, since each of the pair of injection holes can be formed as a simple through-hole, the processing of the injection holes is easy, and the adhesion of foreign matter to the injection holes can be suppressed, thereby suppressing foreign matter contamination.

[0028] In this pipeline, the first reference plane is inclined with respect to the second reference plane so that a portion of the fan-shaped cleaning fluid is directed to the upper vertical portion of the inner surface of the branch pipe in the circumferential direction. This allows for longer lengths for each of the pair of spray holes compared to a configuration where the first reference plane is not inclined with respect to the second reference plane. Consequently, the spray state (mainly the spray shape) of the cleaning fluid can be stabilized, and the components can be cleaned efficiently. Furthermore, since it is easy to direct the cleaning fluid to the upper vertical portion of the inner surface of the branch pipe in the circumferential direction, a wide area of ​​the inner surface of the branch pipe can be efficiently cleaned using the cleaning fluid flowing down from this upper vertical portion. Moreover, since the branch pipes are arranged to extend in a direction intersecting the vertical direction so that their position increases as they move away from the main pipe, the cleaning fluid that has cleaned the inner surface of the branch pipe can be discharged into the main pipe by gravity.

Between the peripheral wall portion 12a and the jacket body 14a, a heat medium passage 50 is configured for flowing a heat medium such as steam or hot water. When the heat medium flows through the heat medium passage 50, the container body 12 is heated by the heat of the heat medium, and consequently the object to be processed contained in the containment space S is heated. A control unit 30 is electrically connected to a pump (not shown) for supplying the heat medium to the jacket 14, and the pump is driven or stopped according to a control signal given by the control unit 30.

[0039] The filtration section 16 has a filter plate 16a provided at the bottom of the containment space S so as to follow the upper surface of the lower wall section 12b.

Although not shown in the figure, the lifting cylinder 58a has a cylinder, a piston that is hydraulically driven inside the cylinder, and a piston rod connected to the piston, the piston rod being connected to the stirring blade 54.

[0044] A valve device (not shown) for supplying hydraulic fluid to the lifting cylinder 58a is electrically connected to a control unit 30. The valve device is operated according to a control signal given by the control unit 30, thereby driving the piston of the lifting cylinder 58a. When the piston is driven and the piston rod is pushed out of the cylinder, the stirring blade 54 is raised. Conversely, when the piston is driven and the piston rod is retracted into the cylinder, the stirring blade 54 is lowered.

[0045] The first leg portion 22 is a rod-shaped member that supports the front of the container 32, and is positioned to extend vertically below the front of the container 32. The front of the lower wall portion 12b that constitutes the container 32 is connected to the upper end of the first leg portion 22 via a pivot shaft (not shown) that extends in a direction perpendicular to the vertical and front-rear directions (left-right direction).

In this embodiment, the inner surface of the container body 12, the nozzle 44 for the drive shaft, and the rotating shaft 54a of the stirring blade 54 are the components to be cleaned. The cleaning device 28 is configured to spray cleaning liquid K onto these components.

[0050] As shown in Figure 2(A), the cleaning device 28 comprises a cleaning device body 64 arranged in the containment space S, a pressure chamber 66 formed inside the cleaning device body 64, a cleaning liquid supply port 68 provided in the cleaning device body 64, at least one (16 in this embodiment) spray nozzles 70a to 70d provided in the cleaning device body 64, and a connecting pipe 72 connected to the cleaning liquid supply port 68.

[0051] The maximum outer diameter of the cleaning device body 64 is set to be smaller than the inner diameter of the opening 48a formed by the cleaning device nozzle 48. Therefore, the user can insert the cleaning device 28 into the housing space S through the opening 48a. In the following description, the end of the cleaning device 28 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."

[0053] The small-diameter cylindrical section 64a is formed in the shape of a straight tube with a circular cross-section, and the large-diameter cylindrical section 64c is formed in the shape of a straight tube with a larger circular cross-section than the small-diameter cylindrical section 64a. The flared section 64b is formed in the shape of a frustoconical pyramid, which widens smoothly towards the tip without any steps. The tapered section 64d is formed in the shape of a cone, which tapers smoothly towards the tip without any steps. The thickness of each of these sections is constant. The base end of the cleaning device body 64, that is, the base end of the small-diameter cylindrical section 64a, is a cleaning fluid supply port 68 for supplying cleaning fluid K (Figure 1) to the pressure chamber 66. In other words, the base end of the cleaning device body 64 is provided with a cleaning fluid supply port 68 for supplying cleaning fluid K to the pressure chamber 66.

[0054] Each of the 16 spray nozzles 70a to 70d is configured to spray the cleaning liquid K (Figure 1) toward the material in a different direction. Specifically, four first spray nozzles 70a are provided on the flared section 64b at 90-degree intervals, and four second spray nozzles 70b are provided on the large-diameter cylindrical section 64c at 90-degree intervals. In addition, four third spray nozzles 70c are provided at the base end of the tapered section 64d at 90-degree intervals, and four fourth spray nozzles 70d are provided at the tip of the tapered section 64d at 90-degree intervals. Figure 2(C) shows four second spray nozzles 70b.

[0055] As shown in Figure 2(B), when the cleaning device body 64 is viewed from a direction perpendicular to the central axis M of the cleaning device body 64, the first injection section 70a, the second injection section 70b, the third injection section 70c, and the fourth injection section 70d are arranged on a virtual straight line extending parallel to the central axis M.

[0056] In this embodiment, the first injection section 70a, the second injection section 70b, and the third injection section 70c are configured in substantially the same manner, while the fourth injection section 70d is configured in a different manner from the others. Therefore, below, we will focus on one third injection section 70c and one fourth injection section 70d and describe their configurations in detail.

[0057] Figure 3(A) is an enlarged view of section IIIA in Figure 2(A), and Figure 3(B) is a cross-sectional view taken along the line IIIB-IIIB in Figure 3(A). Figure 3(A) shows the third injection section 70c and the fourth injection section 70d, and Figure 3(B) shows the third injection section 70c.

[0058] As shown in Figures 3(A) and 3(B), the third injection section 70c has a pair of injection holes 80a and 80b formed in the wall portion 74 of the cleaning device body 64 that constitutes the pressure chamber 66. Each of the pair of injection holes 80a and 80b is a through-hole with a cylindrical inner surface that connects the containment space S, which is the space outside the cleaning device body 64, to the pressure chamber 66.

[0059] As shown in Figure 3(B), the pair of injection holes 80a and 80b are formed such that their centerlines L1 and L2 intersect at a single intersection P, so that the cleaning liquid K sprayed from them in a columnar shape collides with each other and spreads out in a fan shape (Figure 3(A)). The portion of the wall 74 of the cleaning device body 64 in which the pair of injection holes 80a and 80b are formed, i.e., the injection wall portion 82, has a certain thickness and is formed to bulge toward the intersection P.

[0060] As shown in Figure 3(B), if we define the first reference plane Q1 as a virtual plane containing the centerlines L1 and L2 of the pair of injection holes 80a and 80b, respectively, and define the reference points G1 and G2 as the points where the centerlines L1 and L2 of the pair of injection holes 80a and 80b intersect with the virtual outer surface of the wall portion 74 assuming that the injection holes 80a and 80b are not formed, and define the second reference plane Q2 as a virtual plane extending in the thickness direction of the wall portion 74 that includes the two reference points G1 and G2, then the first reference plane Q1 and the second reference plane Q2 overlap each other. In other words, the first reference plane Q1 and the second reference plane Q2 coincide.

[0061] As shown in Figure 3(A), the fourth injection unit 70d has a pair of injection holes 84a and 84b formed in the wall portion 74 of the cleaning device body 64 which constitutes the pressure chamber 66. Each of the pair of injection holes 84a and 84b is a through-hole with a cylindrical inner surface that connects the containment space S, which is the space outside the cleaning device body 64, to the pressure chamber 66.

[0062] The pair of injection holes 84a and 84b are formed such that their centerlines L1 and L2 intersect at a single intersection P, so that the cleaning liquid K sprayed from them in a columnar shape collides with each other and spreads out in a fan shape. The portion of the wall 74 of the cleaning device body 64 in which the pair of injection holes 84a and 84b are formed, i.e., the injection wall portion 86, has a certain thickness and is formed to bulge toward the intersection P.

[0063] If we define a first reference plane Q1 as a virtual plane containing the centerlines L1 and L2 of the pair of injection holes 84a and 84b, respectively, and define reference points G1 and G2 as the points where the centerlines L1 and L2 of the pair of injection holes 84a and 84b intersect with the virtual outer surface of the wall portion 74 assuming that the injection holes 84a and 84b are not formed, and define a second reference plane Q2 as a virtual plane extending in the thickness direction of the wall portion 74, including the two reference points G1 and G2, then the first reference plane Q1 and the second reference plane Q2 intersect. In other words, the first reference plane Q1 and the second reference plane Q2 do not coincide.

[0064] When the angle formed by centerlines L1 and L2 is bisected by a line bisector E, the reference line E of the third injection section 70c and the reference line E of the fourth injection section 70d are located in the same plane. Also, the reference line E of the first injection section 70a and the reference line E of the second injection section 70b are located in the same plane. Therefore, the sector-shaped surfaces of the cleaning fluid K sprayed from injection sections 70a to 70d are located in the same plane.

[0065] As shown in Figure 2(A), the connecting pipe 72 is a straight tubular member for supporting the cleaning device body 64 in the housing space S. A socket 72a is formed at the tip of the connecting pipe 72, and the cleaning fluid supply port 68 of the cleaning device body 64 is connected to the socket 72a. A first flange 72b and a second flange 72c are formed at the base end of the connecting pipe 72. The first flange 72b is connected to the open end 48b of the cleaning device nozzle 48 using a first clamp 88, and the second flange 72c is connected to the downstream end 92a of the cleaning fluid supply pipe 92 using a second clamp 90.

[0066] With the first flange 72b connected to the opening end 48b of the nozzle 48 for the cleaning device, the spray sections 70a to 70d of the cleaning device 28 are directed toward the rotation axis 54a of the stirring blade 54 shown in Figure 1. In other words, the reference lines E (Figure 3(A)) of the spray sections 70a to 70d and the rotation axis 54a are aligned along the same virtual plane (not shown). Therefore, the fan-shaped surface of the cleaning liquid K sprayed from the spray sections 70a to 70d and the rotation axis 54a are aligned along the same virtual plane, allowing the cleaning liquid K to be applied linearly to the rotation axis 54a.

[0067] As shown in Figure 1, the cleaning fluid supply pipe 92 is provided with a pump 94 for supplying cleaning fluid K to the cleaning device 28. The control unit 30 is electrically connected to the pump 94, and the pump 94 is driven or stopped according to a control signal given by the control unit 30.

[0068] The control unit 30 is a device that controls each electrical device necessary to operate the processing unit 10, and is composed of a microcomputer (not shown) consisting of a CPU, ROM, RAM, etc. The ROM stores the operating programs for each electrical device. In Figure 1, the electrical circuit for executing the cleaning process is shown with a dashed line, and the electrical circuits for executing other processes are omitted.

[0069] (Operation of the processing apparatus according to the first embodiment) In the processing apparatus 10 shown in Figure 1, the filtration process, drying process, discharge process, and washing process are performed in this order.

[0070] In the filtration process, the user puts the material to be processed into the containment space S through the opening 46a of the input nozzle 46, and then attaches the lid 46b to the input nozzle 46. The control unit 30 controls the valve device (not shown) of the lifting cylinder 58a to raise the stirring blade 54. It also controls the opening of the on-off valve 42 of the discharge pipe 40. Furthermore, it controls the opening of the on-off valve (not shown) of the gas introduction pipe connected to the container body 12. As a result, the liquid material contained in the material to be processed is discharged through the filter plate 16a and the discharge pipe 40, and the solid material contained in the material to be processed is deposited on the surface of the filter plate 16a.

[0071] During the drying process, the control unit 30 controls a pump (not shown) to supply hot water to the jacket 14. It also controls the valve device (not shown) of the lifting cylinder 58a to lower the stirring blade 54. Furthermore, it controls the rotary drive device 56 to rotate the stirring blade 54. As a result, the material to be processed is heated while being stirred, and dried efficiently.

[0072] In the discharge process, the control unit 30 controls the opening of the lid 38a of the discharge port 38. It also controls the valve device (not shown) of the tilting cylinder 26a to lift the rear of the container body 12. Furthermore, it controls the vibration generating unit 18c of the vibration generating device 18 to drive, and controls the rotary drive device 56 to rotate the stirring blade 54. As a result, the processed material (solid matter) obtained through the filtration and drying processes is discharged from the discharge port 38.

[0073] In the cleaning process, the control unit 30 controls the pump 94 to supply cleaning liquid K to the cleaning device 28. It also controls the rotary drive device 56 to rotate the stirring blade 54. Furthermore, it controls the on / off valve 42 of the discharge pipe 40 to open. As a result, cleaning liquid K is sprayed from the spray sections 70a to 70d of the cleaning device 28 toward the inner surface of the container body 12, the drive shaft nozzle 44, and the rotation shaft 54a of the stirring blade 54, and these surfaces are cleaned. The control unit 30 may also control the valve device (not shown) of the lifting cylinder 58a to repeatedly move the stirring blade 54 up and down, or it may control the valve device (not shown) of the lifting cylinder 58a to gradually move the stirring blade 54 up and down.

[0074] (Effects of the processing apparatus according to the first embodiment) According to the processing apparatus 10 and cleaning apparatus 28 of the first embodiment, the above configuration can achieve the following effects. Specifically, as shown in Figure 3(A), the cleaning liquid K sprayed in a columnar shape from a pair of spray holes 80a, 80b and 84a, 84b collide with each other and spread in a fan shape. Therefore, by appropriately selecting the position, size, and orientation of each of the pair of spray holes 80a, 80b and 84a, 84b, the spray pattern of the cleaning liquid K can be appropriately determined according to the position and shape of the member. In other words, the degree of design freedom regarding the spray pattern of the cleaning liquid K can be increased, and the member to be cleaned can be cleaned efficiently. Furthermore, since each of the pair of spray holes 80a, 80b and 84a, 84b can be formed as a simple through-hole, the processing of the spray holes is easy, the adhesion of foreign matter can be suppressed, and consequently, foreign matter contamination can be suppressed.

[0075] As shown in Figures 3(A) and (B), the spray wall portion 82 in which a pair of spray holes 80a and 80b are formed, and the spray wall portion 86 in which a pair of spray holes 84a and 84b are formed, have a certain thickness and are formed to bulge toward the intersection P side. Therefore, compared to the case where they do not bulge toward the intersection P side, the lengths of each of the spray holes 80a, 80b and 84a, 84b can be increased. Consequently, the spray state (mainly the spray shape) of the cleaning liquid K sprayed from each of the spray holes 80a, 80b and 84a, 84b can be stabilized, and the material can be cleaned efficiently.

[0076] As shown in Figure 3(A), in the third injection section 70c, the first reference plane Q1 and the second reference plane Q2 coincide, so the lengths of the pair of injection holes 80a and 80b are minimized. In the fourth injection section 70d, the first reference plane Q1 and the second reference plane Q2 intersect, so the lengths of the pair of injection holes 84a and 84b can be increased compared to the case where the first reference plane Q1 and the second reference plane Q2 coincide. Therefore, the spray state (mainly the spray shape) of the cleaning liquid sprayed from each of the pair of injection holes 84a and 84b can be stabilized, and the material can be cleaned efficiently.

[0077] The first angle at which the first reference plane Q1 and the second reference plane Q2 intersect in the third injection section 70c is "0 degrees," and the second angle at which the first reference plane Q1 and the second reference plane Q2 intersect in the fourth injection section 70d is "30 degrees," and these angles are defined to be different. Therefore, it is possible to increase the degree of freedom in the design regarding the spraying manner of the cleaning liquid K, and the components can be cleaned efficiently. Note that the above first angle and the above second angle may be changed as appropriate.

[0078] As shown in Figure 2(B), the tapered portion 64d of the cleaning device body 64 is formed in a conical shape that tapers smoothly towards the tip without any steps. Therefore, the cleaning liquid K adhering to the surface of the cleaning device body 64 can flow down the surface of the tapered portion 64d and fall from the tip of the tapered portion 64d. Consequently, even if foreign matter adheres to the surface of the cleaning device body 64, the foreign matter can be efficiently washed away with the cleaning liquid K.

[0079] As shown in Figure 2(B), the flared portion 64b of the cleaning device body 64 is formed in a frustoconical shape that widens smoothly towards the tip without any steps. This makes it possible to increase the surface area of ​​the flared portion 64b and the large-diameter cylindrical portion 64c connected to the flared portion 64b, and facilitates the formation of the first jet portion 70a and the second jet portion 70b.

[0080] The processing device 10 rotates the elongated rotating shaft 54a with a rotary drive device 56 (Figure 1) while cleaning it with a cleaning device 28. Therefore, even if there is only one cleaning device 28, the rotating shaft 54a can be cleaned evenly.

[0081] (modified version) In carrying out the present invention, the invention is not limited to the embodiments described above, and various modifications are possible as long as they do not depart from the purpose of the invention.

[0082] Figure 4(A) is a cross-sectional view showing the injection section 96 according to the first modified example, and Figure 4(B) is a cross-sectional view showing the injection section 98 according to the second modified example. Figure 5(A) is a cross-sectional view showing the injection section 100 according to the third modified example, and Figure 5(B) is an enlarged view of the VB portion in Figure 5(A).

[0083] As shown in Figure 3(B), in the third injection unit 70c of the above embodiment, the reference line E that bisects the angle formed by the centerlines L1 and L2 of the pair of injection holes 80a and 80b is arranged to extend in the thickness direction of the wall 74. However, as in the injection unit 96 according to the first modified example shown in Figure 4(A), the reference line E that bisects the angle formed by the centerlines L1 and L2 of the pair of injection holes 102a and 102b may be arranged to extend in a direction intersecting the thickness direction of the wall 74. In other words, when the line segment (not shown) connecting two reference points G1 and G2 is bisected and the imaginary straight line extending in the thickness direction of the wall 74 is taken as the direction line X, the reference line E may be arranged to extend in a direction intersecting the direction line X. Even in this case, the entire cleaning liquid K can be sprayed in the direction along the reference line E, so the spray direction of the cleaning liquid K can be adjusted according to the position of the member to be cleaned.

[0084] As shown in Figure 3(B), in the third injection unit 70c of the above embodiment, the inner diameters of the pair of injection holes 80a and 80b are set to be the same size. However, as in the injection unit 98 of the second modified example shown in Figure 4(B), the inner diameters of the pair of injection holes 104a and 104b may be set to be different. In this case, the cleaning liquid K injected from the injection hole 104a with a larger inner diameter will be dominant over the cleaning liquid injected from the injection hole 104b with a smaller inner diameter, so the overall injection direction of the cleaning liquid K will be biased toward the injection direction side of the injection hole 104a with respect to the reference line E. Therefore, the overall injection direction of the cleaning liquid K can be adjusted by adjusting the size of the inner diameters of the pair of injection holes 104a and 104b.

[0085] As shown in Figure 3(B), in the third injection section 70c of the above embodiment, the injection wall section 82, in which a pair of injection holes 80a and 80b are formed in the wall section 74, is curved in an arc shape so as to bulge toward the intersection P side. However, as in the injection section 100 according to the third modified example shown in Figures 5(A) and (B), the injection wall section 108, in which a pair of injection holes 106a and 106b are formed in the wall section 74, may be bent so as to bulge toward the intersection P side. In the injection section 100 according to the third modified example, one injection hole 106a is formed at the base end of the large-diameter cylindrical section 64c, and the other injection hole 106b is formed at the tip of the flared section 64b.

[0086] Figure 6(A) is a perspective view showing the configuration of the cleaning device body 110 according to the first modified example, Figure 6(B) is a perspective view showing the configuration of the cleaning device body 111 according to the second modified example, Figure 6(C) is a perspective view showing the configuration of the cleaning device body 112 according to the third modified example, and Figure 6(D) is a perspective view showing the configuration of the cleaning device body 114 according to the fourth modified example.

[0087] As shown in Figure 2(B), the cleaning device body 64 of the above embodiment has a small-diameter cylindrical portion 64a, a flaring portion 64b, a large-diameter cylindrical portion 64c, and a tapered portion 64d. However, the shape of the cleaning device body is not limited to this and may be changed as appropriate. For example, the tapered portion 64d may be omitted, as in the cleaning device body 110 according to the first modified example shown in Figure 6(A), or the large-diameter cylindrical portion 64c may be omitted, and the flaring portion 64b and the tapered portion 64d may be directly connected, as in the cleaning device body 111 according to the second modified example shown in Figure 6(B). Furthermore, as in the cleaning device body 112 according to the third modified example shown in Figure 6(C), the portion excluding the small-diameter cylindrical portion 64a may be changed to a spherical portion 116, or as in the cleaning device body 114 according to the fourth modified example shown in Figure 6(D), the portion excluding the small-diameter cylindrical portion 64a may be changed to a rectangular parallelepiped or cubic portion 118.

[0088] In the above embodiment, the processing apparatus 10 is configured as a filtration and drying apparatus. However, the processing apparatus of the present invention does not necessarily have to be configured as a filtration and drying apparatus. For example, it may be configured as a filtration apparatus without a drying function, or as a drying apparatus without a filtration function. It may also be configured as a reaction tank for treating the material to be processed.

[0089] Figure 7 is a cross-sectional view showing the configuration of the processing apparatus according to the second embodiment. The processing apparatus 120 according to the second embodiment is configured as a reaction tank for reactively processing a material to be processed, and comprises a container body 122, a stirring device 124, a baffle 126, and a container 128 having the above-mentioned cleaning device 28. The stirring blade 130 constituting the stirring device 124 has a rotating shaft 130a. The baffle 126 is a so-called baffle plate for causing changes in the flow of the material to be processed stirred by the stirring blade 130, and has a baffle body 126a formed in an elongated shape that extends linearly (including rod-shaped). The rotating shaft 130a of the stirring blade 130 and the baffle body 126a of the baffle 126 are arranged parallel to each other with a distance between them, and the cleaning device 28 is positioned between them. Therefore, the rotating shaft 130a and the baffle body 126a can be efficiently cleaned by the cleaning liquid K sprayed from the cleaning device 28.

[0090] In the above embodiment, the rotating shaft 54a, which is a component (object to be cleaned), is rotated by the rotary drive device 56. However, the component rotated by the rotary drive device 56 is not limited to the rotating shaft 54a. For example, it may be a cylindrical cover component (not shown) arranged around the rotating shaft 54a to protect it. This cover component is formed in an elongated shape, similar to the rotating shaft 54a, and rotates together with the rotating shaft 54a. Therefore, the processing device 10 can efficiently clean the cover component with the cleaning device 28.

[0091] (Conduit configuration according to the first embodiment) In the above embodiment, the cleaning device 28 is used in the processing device 10, but the cleaning device of the present invention may also be used in a pipeline. Figure 8 is a cross-sectional view showing the configuration of the pipeline 132 according to the first embodiment.

[0092] The pipeline 132 shown in Figure 8 comprises a main pipe 136 extending vertically, a first branch pipe 138 and a second branch pipe 140 branching off from the pipe wall 136a of the main pipe 136, and a cleaning device 142 for cleaning the inner surfaces of the first branch pipe 138 and the second branch pipe 140 with cleaning solution K. The main pipe 136 may also be arranged to extend in a direction intersecting the vertical direction.

[0093] The main pipe 136 is a straight tubular member that constitutes a space U that communicates with the containment space S. A first flange 136b is formed at the lower end of the main pipe 136, and the first flange 136b is connected to the opening end 48b of the cleaning device nozzle 48 using a first clamp 144. A second flange 136c is formed at the upper end of the main pipe 136.

[0094] The first branch pipe 138 and the second branch pipe 140 are positioned so that their position increases as they move away from the main pipe 136. The ends 138a and 140a of the first branch pipe 138 and the second branch pipe 140 that are furthest from the main pipe 136 are closed, and devices such as pressure sensors and temperature sensors 138b and 140b are installed inside these ends.

[0095] The cleaning device 142 comprises a tubular cleaning device body 146 arranged inside the main pipe 136 and extending in the longitudinal direction of the main pipe 136, a pressure chamber 148 formed inside the cleaning device body 146, a cleaning liquid supply port 150 provided on the cleaning device body 146 to supply cleaning liquid K to the pressure chamber 148, and two spraying parts 152, 152 provided on the cleaning device body 146 to spray cleaning liquid K toward the inner surfaces of the first branch pipe 138 and the second branch pipe 140, respectively.

[0096] Each of the injection units 152, 152 is basically configured in the same way as the fourth injection unit 70d shown in Figure 3(A), so redundant explanations will be omitted. However, in each of the injection units 152, 152, the inclination angle of the first reference plane Q1 with respect to the second reference plane Q2 is determined so that a portion of the cleaning fluid K that spreads out in a fan shape is directed to the upper vertical part in the circumferential direction of the inner surface of the first branch pipe 138 and the second branch pipe 140, respectively.

[0097] The lower end of the cleaning device body 146 is closed, and a first flange 146a and a second flange 146b are formed at the upper end of the cleaning device body 146. The first flange 146a is connected to the second flange 136c of the main pipe 136 using a second clamp 154, and the second flange 146b is connected to the downstream end 92a of the cleaning fluid supply pipe 92 using a clamp 156.

[0098] In this pipeline 132, each injection unit 152, 152 is basically configured in the same way as the fourth injection unit 70d shown in Figure 3(A), and therefore it can achieve the same effects as the processing device 10 described above. In particular, the spray pattern of the cleaning liquid K sprayed from the cleaning device 142 can be appropriately determined according to the position and shape of the inner surfaces of the first branch pipe 138 and the second branch pipe 140, respectively.

[0099] Furthermore, the cleaning solution K can be allowed to flow down the inner surfaces of the first branch pipe 138 and the second branch pipe 140, thereby efficiently cleaning their inner surfaces. In addition, since the first branch pipe 138 and the second branch pipe 140 are positioned so that their height increases as they move away from the main pipe 136, as shown by the white arrows in Figure 8, the cleaning solution K that has flowed down the inner surfaces of the first branch pipe 138 and the second branch pipe 140 can be discharged into the internal space U of the main pipe 136 by gravity, and foreign matter adhering to the surface of the cleaning device body 146 can be washed away with the cleaning solution K.

[0100] (Conduit configuration according to the second embodiment) Figure 9 is a cross-sectional view showing the configuration of the pipeline 134 according to the second embodiment. The pipeline 132 shown in Figure 8 is equipped with a cleaning device 142 for cleaning the inner surfaces of the first branch pipe 138 and the second branch pipe 140 with cleaning liquid K. However, as in the pipeline 134 shown in Figure 9, the cleaning device 142 may be combined with the cleaning device 28 shown in Figures 2(A) and (B).
