Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a container cleaning device and a factory building for installing the container cleaning device. Background Technology

[0002] Silos or storage tanks are used in various manufacturing sectors, including packaging, warehousing, chemicals, pharmaceuticals, and food processing. After use, impurities can adhere to the inner walls of these containers, affecting product quality. Therefore, manufacturers regularly clean and dry silos or storage tanks.

[0003] Currently, some manufacturers manually clean their containers and allow them to air dry before reuse. Manual cleaning is not only time-consuming and labor-intensive, but also limits the cleaning area for deeper storage tanks and can lead to secondary contamination, affecting product quality. Therefore, there is room for improvement in container cleaning equipment. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a container cleaning device to improve cleaning efficiency, convenience, and cleanliness, while reducing labor and time costs.

[0005] Another objective of this invention is to propose a factory for installing the aforementioned container cleaning device.

[0007] The container cleaning device of this application is equipped with a water tank to ensure sufficient water is stored before cleaning, guaranteeing quick cleaning and eliminating the need for long waiting times. A lifting device allows the height of the first nozzle to be adjustable, raising it when not needed to prevent workers from bumping into it. It can also lower itself when cleaning is required to accommodate different container heights. A water pump ensures sufficient water pressure for rinsing the containers, utilizing the impact force of the water flow to clean them more thoroughly. A splash guard reduces water waste and prevents water from splashing onto nearby people or equipment.

[0008] In the container cleaning device, the first nozzle is designed to be height-adjustable, which can adapt to the cleaning of various containers of different heights, making it convenient to use and widely applicable.

[0012] Furthermore, there are at least two rigid tube segments, and the first nozzle can be detachably connected to the lower end of each of the rigid tube segments;

[0013] One of the rigid pipe sections is a fixed pipe section, and the remaining rigid pipe sections are detachable pipe sections. The upper end of the fixed pipe section is fixedly connected to the lower end of the piston pipe, and the upper end of the detachable pipe section is detachably connected to the lower end of the fixed pipe section.

[0014] When there are at least two detachable pipe segments, each pair of detachable pipe segments is detachably connected.

[0015] In some embodiments, the splash guard is a circular metal cover with the center of the splash guard connected to the first water supply pipe, and the splash guard is a conical shape that gradually descends from the center to the edge, and the splash guard is used to cover the top of the first container opening.

[0016] In some embodiments, the splash guard is fitted onto the first water supply pipe and can slide up and down relative to the first water supply pipe;

[0017] The first nozzle is stopped below the splash guard, or the outer periphery of the first water pipe is provided with a limiting clip for stopping below the splash guard.

[0018] In some embodiments, the container cleaning device further includes: a guide rail disposed on the ground, one end of the guide rail extending below the first nozzle, the guide rail cooperating with the container to guide the container to move.

[0019] In some embodiments, the container cleaning device further includes: a limiting structure disposed on the ground, the limiting structure including: a stop portion for cooperating with the container to stop the container during container cleaning, and the position of the stop portion is adjustable.

[0020] Specifically, the container cleaning device further includes: a guide rail on the ground, and the limiting structure further includes: a limiting rail on the guide rail, the limiting rail extending along the length direction of the guide rail, and the limiting rail having at least one limiting groove.

[0021] The stop portion can be inserted into the limiting groove and can be pulled out from the limiting groove. The stop portion is used to block at least one side of the container to position the container.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] It is worth noting that the application of the container cleaning device 10 in this application is not limited. It can be used in pharmaceutical manufacturing plants to clean storage tanks, silos, etc., and can also be applied to other scenarios and objects.

[0052] For example, in industrial production, food processing, medical and health fields, and laboratory and scientific research fields, various storage tanks, reaction vessels, pipelines, and other containers are used, which often require regular cleaning to remove residues, stains, and impurities. The container cleaning device 10 of this application can complete the internal cleaning of these containers, improving production efficiency while ensuring product quality. It should also be emphasized that the shape and type of the containers to be cleaned by the device in this application are not limited, nor is the function of the containers limited. They can be storage containers (such as storage tanks), reaction vessels (such as reaction vessels), flow guiding containers (such as pipelines), etc.

[0053] The container cleaning apparatus 10 according to a first aspect of the present invention is described below with reference to the accompanying drawings.

[0054] According to the embodiment of the present utility model, the container cleaning device 10 is installed outdoors or in a factory building 100 to clean containers 200.

[0055] Reference Figure 1 The container cleaning device 10 includes: a water tank 11, a first water supply pipe 12, a first nozzle 13, a lifting device 15, a water pump 141, and a splash guard 142.

[0056] Water tank 11 is used to store water. One end of the first water supply pipe 12 is connected to water tank 11, and the first nozzle 13 is connected to the other end of the first water supply pipe 12. Lifting device 15 is connected to the factory building 100 or a support frame. Lifting device 15 is connected to the first water supply pipe 12 or the first nozzle 13 to drive the first nozzle 13 to rise and fall. If the container cleaning device 10 is installed inside the factory building 100, the lifting device 15 can be directly installed on the roof or wall of the factory building 100, or a support frame can be set up inside the factory building 100, with the lifting device 15 mounted on the support frame so that the first nozzle 13 can be suspended above the container 200 to be rinsed. If the container cleaning device 10 is installed outdoors, a support frame is required, with the lifting device 15 mounted on the support frame so that the first nozzle 13 can be suspended above the container 200 to be rinsed. If the support frame is installed inside the factory building 100, the support frame can be a steel structure frame or a pipe fixing frame installed inside the factory building 100.

[0057] The water pump 141 is used to pump water from the first water supply pipe 12 to the first nozzle 13. The splash cover 142 is connected to the first water supply pipe 12 or the first nozzle 13 to cover the first container opening 201 when water is sprayed from the first nozzle 13.

[0058] like Figure 1 As shown, the normally used container 200 has a first container opening 201 and a second container opening 202. When rinsing the container 200 using the container cleaning device 10, the first container opening 201 is used as the water inlet, and the second container opening 202 is used as the water outlet. The positions of the first container opening 201 and the second container opening 202 on the container 200 are not limited. Taking a fermentation tank as an example, some fermentation tanks have an opening at the top for feeding materials and an opening at the bottom for assembling the stirring assembly. When cleaning the fermentation tank, the stirring assembly will be removed. At this time, the top opening can be used as the first container opening 201, and the bottom opening can be used as the second container opening 202. Of course, the position and number of openings on different containers 200 are not limited according to their own uses. Therefore, during cleaning, appropriate openings can be selected as the first container opening 201 and the second container opening 202, respectively.

[0059] When using the container cleaning device 10, first move the container 200 to be cleaned to below the first nozzle 13, then start the lifting device 15 to lower the first nozzle 13 so that the first nozzle 13 can face the first container opening 201 or enter the container 200. Since the splash cover 142 is connected to the first water supply pipe 12 or the first nozzle 13, the splash cover 142 lowers synchronously when the first nozzle 13 lowers. The splash cover 142 covers the first container opening 201. When the first nozzle 13 sprays water, the splash cover 142 covers the first container opening 201, which can prevent the cleaning water from splashing out of the first container opening 201 when it hits the container wall.

[0060] The container cleaning device 10 of this application is equipped with a water tank 11 to store water, ensuring that sufficient water is stored in advance for cleaning, thus ensuring quick cleaning and eliminating the need to wait for water, which would cause the cleaning time to be too long. It should be added that the water tank 11 can be used without external water supply or can be connected to a water source, such as a tap water pipe connected to the water tank 11.

[0061] By setting up a water pump 141, the water in the rinsing container 200 is given a certain water pressure, and the water pressure impact force can rinse the container 200 more thoroughly. The splash cover 142 is designed to reduce water waste and prevent water from splashing onto surrounding people or equipment.

[0062] In some designs, the first nozzle 13 sprays water in a jet pattern. This increases the water jet velocity and impact force, while also increasing the spray area, thereby enhancing the cleaning power and efficiency while reducing water waste. Furthermore, by controlling the water consumption of a single container 200, the water stored in the tank 11 can be used to clean more containers 200 at once, increasing the number of containers 200 that can be cleaned.

[0063] The container cleaning device 10 can adapt to cleaning various containers 200 of different heights in the factory by raising and lowering the first nozzle 13 through the lifting device 15. It is convenient to use and widely applicable. That is, when it is necessary to clean a taller container 200, the first nozzle 13 can be raised, and when it is necessary to clean a shorter container 200, the first nozzle 13 can be lowered.

[0064] Furthermore, before removing the container 200 after cleaning, the first nozzle 13 can be raised, causing the splash guard 142 to rise as well. This ensures that the first nozzle 13 and the splash guard 142 will not interfere with the movement of the container 200. In addition, the first nozzle 13 is designed to be height-adjustable, eliminating the need for workers to hold it. When the container 200 is moved, there is no need to remove the first water pipe 12 and the splash guard 142, thus eliminating concerns about workers tripping over them. Overall, it is very convenient to use.

[0065] The structure described above is precisely what is used in this application, allowing the container cleaning device 10 to be installed outdoors or inside a factory building 100. Specifically, in existing solutions, the container cleaning device itself includes a washing and drying chamber, with a spray assembly installed inside. The washing and drying chamber has a door; after the container is moved into the chamber through the door, the door is closed, and then the spray assembly is turned on to rinse the container. The washing and drying chamber itself is quite large, and is typically made of metal, resulting in a large and bulky overall structure that occupies excessive space and is costly.

[0066] In this application, the washer-dryer compartment is removed, and the first container opening 201 is covered by a splash guard 142 to prevent water from splashing during internal cleaning, thus eliminating the need for a separate washer-dryer compartment.

[0067] In this application, the lifting device 15 has various structural forms.

[0068] For example, the lifting device 15 includes a linear motor, the stator of which is fixed to the factory building 100 or a support, and the mover of which is connected to the first water supply pipe 12 or the first nozzle 13. The linear motor can adopt an existing known structure, which will not be described in detail here.

[0069] Alternatively, the lifting device 15 includes a motor and a transmission assembly. The motor is fixed to the factory building 100 or a support frame. One end of the transmission assembly is connected to the motor, and the other end is connected to the first water supply pipe 12 or the first nozzle 13. The transmission assembly can be a gear and rack mechanism, with the gear connected to the motor, the rack meshing with the gear, and the rack connected to the first water supply pipe 12 or the first nozzle 13. After the motor starts running, it drives the gear to rotate, and the gear drives the rack to rise and fall. The rise and fall of the rack, in turn, drives the first nozzle 13 to rise and fall.

[0070] The transmission component can also be a lead screw and nut mechanism, with the lead screw connected to the motor and the nut engaging with the lead screw. After the motor starts running, it drives the lead screw to rotate, and the lead screw drives the nut to rise and fall. The nut is connected to the first water supply pipe 12 or the first nozzle 13, thereby driving the first nozzle 13 to rise and fall.

[0071] In some specific embodiments, such as Figure 1 As shown, the lifting device 15 is a cylinder structure. The cylinder structure includes: cylinder barrel 151, piston 152 and piston rod 153.

[0072] The cylinder 151 is used to fix the cylinder to the factory building 100 or the support, and the cylinder 151 is arranged vertically. The piston 152 is vertically slidably disposed inside the cylinder 151, and the piston rod 153 is vertically disposed and connected to the piston 152. The piston rod 153 is connected to the first water supply pipe 12.

[0073] The lifting device 15 uses a cylinder structure, which has a relatively large load capacity, can adapt to different production environments, and has overload protection capabilities.

[0074] Specifically, the piston rod 153 has a cavity 1531 to form a piston tube. For example... Figure 1 As shown, the first water supply pipe 12 includes a flexible hose section 122 and a rigid pipe section 123. One end of the flexible hose section 122 is connected to the water tank 11, and the other end of the flexible hose section 122 is connected to the piston tube. The upper end of the rigid pipe section 123 is connected to the lower end of the piston tube, and the lower end of the rigid pipe section 123 is connected to the first nozzle 13. A splash guard 142 is connected to the rigid pipe section 123.

[0075] By setting the piston rod 153 as a piston tube, water can be passed through it, eliminating the need for a complex pipeline connection structure, which can simplify the structure and save costs.

[0076] The piston tube is connected to the hose section 122 at the water inlet end. The hose section 122 can swing as the piston rod 153 moves up and down, but the water can still flow smoothly from the hose section 122 to the piston rod 153 during the swing. Optionally, the hose section 122 can be a rubber tube, a flexible plastic tube, etc.

[0077] A rigid pipe section 123 is connected to the lower end of the piston tube. The rigid pipe section 123 is connected to the first nozzle 13, and the water exiting from the first nozzle 13 will generate a certain impact force. Therefore, connecting the first nozzle 13 with the rigid pipe section 123 is beneficial to use the rigidity of the rigid pipe section 123 to avoid back-and-forth swaying when subjected to impact, thereby improving the safety of use.

[0078] In some specific embodiments, only one rigid tube segment 123 is needed, and the lifting range of the piston rod 153 is the same as the lifting range of the first nozzle 13. This limits the range of container heights that can be accommodated.

[0079] In other specific embodiments, such as Figure 1 As shown, to expand the height range of the container 200 that the device can accommodate, at least two rigid tube segments 123 can be configured, and the first nozzle 13 can be detachably connected to the lower end of each rigid tube segment 123. One rigid tube segment 123 is a fixed tube segment 1231, and the remaining rigid tube segments 123 are detachable tube segments 1232. The upper end of the fixed tube segment 1231 is fixedly connected to the lower end of the piston tube, and the upper end of the detachable tube segment 1232 is detachably connected to the lower end of the fixed tube segment 1231. When there are at least two detachable tube segments 1232, every two detachable tube segments 1232 are detachably connected.

[0080] Taking two rigid pipe sections 123 as an example, one is a fixed pipe section 1231, and the other is a detachable pipe section 1232. Assuming the lifting range of the piston rod 153 is 0.5m, when only the fixed pipe section 1231 is installed at the lower end of the piston rod 153, the height of the first nozzle 13 can be adjusted within the range of 1.5m to 2m. When both the fixed pipe section 1231 and the detachable pipe section 1232 are installed at the lower end of the piston rod 153, and the length of the detachable pipe section 1232 is 0.5m, the height of the first nozzle 13 can be adjusted within the range of 1m to 1.5m. The total height adjustment range of the first nozzle 13 is between 1m and 2m. When cleaning a container 200 with a height between 1m and 1.5m, the detachable pipe section 1232 needs to be installed. When cleaning a container 200 with a height between 1.5m and 2m, the detachable pipe section 1232 needs to be removed.

[0081] Therefore, by configuring the rigid pipe section 123 to include a fixed pipe section 1231 and a detachable pipe section 1232, the height range of the container 200 to be cleaned by the device can be increased.

[0082] Similarly, there are three rigid pipe sections 123: one fixed pipe section 1231 and two detachable pipe sections 1232. There are two detachable pipe sections 1232, each 0.5m in length. When the fixed pipe section 1231 is installed at the lower end of the piston rod 153, one detachable pipe section 1232 is installed at the lower end of the fixed pipe section 1231, and another detachable pipe section 1232 is installed at the lower end of each detachable pipe section 1232, the height of the first nozzle 13 can be adjusted within the range of 0.5m to 1m. The total adjustment range of the first nozzle 13's height is between 0.5m and 2m.

[0083] According to the above example, the more detachable tube segments 1232 there are, the greater the total range of height adjustment of the first nozzle 13.

[0084] Optionally, when the fixed pipe section 1231 and the detachable pipe section 1232 are connected, a clamp can be installed between them. When two detachable pipe sections 1232 are connected, a clamp can be installed between them. The clamp is low in cost and easy to install and remove.

[0085] In some embodiments, such as Figure 1 As shown, the splash cover 142 is a circular metal cover. The center of the splash cover 142 is connected to the first water supply pipe 12. The splash cover 142 is a conical shape that gradually descends from the center to the edge. The splash cover 142 is used to cover the top of the first container opening 201.

[0086] Here, the splash guard 142 is made of metal, which has high structural strength, strong resistance to water flow impact, is not easily deformed, and has a long service life.

[0087] In related technologies, most common containers 200 have a circular opening shape. Therefore, setting the splash guard 142 as a circular cover can accommodate a large number of containers 200 and has a wide range of applications.

[0088] The splash cover 142 is designed as a cone shape that gradually descends from the center to the edge. On the one hand, when the splash cover 142 is placed on the container 200, it is not easy for the splash cover 142 to collapse downwards when subjected to external impact, such as when a foreign object hits the splash cover 142, thus avoiding the risk of the splash cover 142 collapsing and getting stuck inside the container 200.

[0089] Furthermore, the splash cover 142 is designed as a cone shape that gradually descends from the center to the edge. When water splashes onto the splash cover 142, the water flow easily flows downwards along the splash cover 142. Thus, the splash cover 142 can guide the water flow to the wall of the container 200, allowing the water flow to carry away the stains on the container wall.

[0090] Specifically, such as Figure 1 As shown, the splash guard 142 is fitted onto the first water supply pipe 12 and can slide up and down relative to the first water supply pipe 12. That is to say, the height of the splash guard 142 relative to the first nozzle 13 is adjustable.

[0091] With this configuration, when the first nozzle 13 descends to the first container opening 201 and extends into the container 200 from the first container opening 201, the splash guard 142 can cover the first container opening 201 and stop descending. At this time, the first nozzle 13 can spray water onto the container wall at a higher position in the container 200.

[0092] If the internal space of container 200 is large, the height of the first nozzle 13 can be lowered, and the first nozzle 13 can spray water onto the lower part of the container wall of container 200. Since the splash cover 142 can slide up and down relative to the first water supply pipe 12, when the first nozzle 13 is lowered, the height of the splash cover 142 can remain unchanged, and the splash cover 142 can still cover the opening 201 of the first container.

[0093] The adjustable height of the splash cover 142 relative to the first nozzle 13 allows the splash cover 142 to remain covering the first container opening 201, while the cleaning height range of the first nozzle 13 inside the container 200 is adjustable, increasing cleaning flexibility and helping to improve cleanliness.

[0094] Furthermore, to prevent the splash guard 142 from falling off, the first nozzle 13 can be used to stop it below the splash guard 142. Alternatively, a limiter can be installed on the outer periphery of the first water supply pipe 12 to stop it below the splash guard 142.

[0095] In some embodiments, such as Figure 1 and Figure 2 As shown, the container cleaning device 10 also includes a water collection structure 16 disposed below the container 200, the water collection structure 16 being used to collect water flowing out of the container 200.

[0096] The container cleaning device 10 also includes a drainage structure 17 located below the container 200, which is used to drain water flowing out of the container 200.

[0097] Understandably, different wastewater treatment structures can be selected based on the needs of different application scenarios. For example, only the water collection structure 16 can be installed to collect the wastewater, which can then be transported away by a transport vehicle. Alternatively, if the local sewer system has sufficient drainage capacity, only the drainage structure 17 can be installed. The drainage structure 17 can be a drain pipe 172, with one end directly connected to the second container opening 202 and the other end directly connected to the local sewer system. Wastewater can then be discharged directly through the drainage structure 17 without needing to be collected.

[0098] Alternatively, for example, if the cleaning location is near a local drainage ditch, neither a water collection structure 16 nor a drainage structure 17 needs to be installed. After the wastewater flows to the ground, it flows from the ground towards the drainage ditch. Some containers 200 may not have toxic wastewater after cleaning, and the degree of dirt may not be very deep. Therefore, the cleaning water can be reused, such as for watering the flowers, trees, and farmland around the container.

[0099] In some designs, the container cleaning device 10 includes both a water collection structure 16 and a drainage structure 17.

[0100] Specifically, such as Figure 1 and Figure 2 As shown, when the water collection structure 16 is provided, the water collection structure 16 can be a liquid collection tank 161 located below the container 200. Because the liquid collection tank 161 is located below the container 200, it can collect sewage discharged from the container 200 and can also collect other sewage from the vicinity, thus having a strong water collection capacity.

[0101] Furthermore, such as Figure 2 As shown, the drainage structure 17 is a drain outlet 171 located at the lowest point of the liquid collection tank 161. This allows the water in the liquid collection tank 161 to be completely drained.

[0102] Furthermore, such as Figure 2 As shown, the drainage structure 17 also includes a drain pipe 172 connected to the drain outlet 171.

[0103] In some embodiments, such as Figure 1 As shown, the container cleaning device 10 also includes a second water supply pipe 18 and a second nozzle 19. One end of the second water supply pipe 18 is connected to the water tank 11, and the second nozzle 19 is connected to the other end of the second water supply pipe 18. The second nozzle 19 is used to spray water toward the outside of the container 200, and the water pump 141 is used to pump water from the second water supply pipe 18 to the second nozzle 19. In other words, the outer surface of the container 200 can be rinsed through the second water supply pipe 18 and the second nozzle 19, which improves the flexibility of cleaning the container 200. Workers can rinse the outer surface of the container 200 according to the degree of dirt on the surface.

[0104] Specifically, the second water supply pipe 18 can be entirely made of flexible tubing, allowing workers to flexibly adjust the position and angle of the second nozzle 19 when spraying water into the container 200. One end of the second water supply pipe 18 can be directly connected to the water pump 141, and the other end can also be connected to the first water supply pipe 12, thus intermittently connecting the water pump 141. In this way, the water pump 141 can simultaneously operate both the first nozzle 13 and the second nozzle 19.

[0105] Furthermore, a control switch 191 is provided on the second nozzle 19. This allows the worker to flexibly choose whether to turn on the control switch 191 to flush the water while holding the second nozzle 19, making operation convenient.

[0106] In some embodiments, such as Figure 1 As shown, the container cleaning device 10 also includes a guide rail 30 disposed on the ground, one end of which extends below the first nozzle 13. The guide rail 30 cooperates with the container 200 to guide the container 200 to move. The guide rail 30 facilitates the guidance of the container 200 from its usual use position to below the first nozzle 13, thus facilitating the transfer of the container 200.

[0107] Specifically, such as Figure 1 As shown, a guide groove 301 is formed on the guide rail 30 to assemble the sliding member 203 at the bottom of the container 200. Here, the sliding member 203 can be a roller or a slider. The guide groove 301 can reduce the probability of derailment.

[0108] Specifically, the guide rail 30 is provided with at least one set of grooves, each set of grooves including two guide grooves 301 and corresponding to a track gauge. That is to say, the distance between the two guide grooves 301 is the track gauge, which is equal to the horizontal distance of the sliding member 203 at the bottom of the container 200.

[0109] When the guide rail 30 has at least two sets of grooves, the track gauges corresponding to different sets of grooves are not the same. In this way, the guide rail 30 can guide containers 200 with different track gauges, thereby increasing the applicability of the guide rail 30.

[0110] In some designs, the guide rail 30 has only one set of slots, which includes two guide slots 301. The bottom of the container 200 has two rows of sliding members 203. One row of sliding members 203 rolls within one guide slot 301, and the other row rolls within the other guide slot 301. Each guide slot 301 is relatively wide, allowing the two rows of sliding members 203 on the container 200 to move on the guide rail 30 even when the distance between them is not equal.

[0111] In some embodiments, the container cleaning device 10 further includes a limiting structure 50 disposed on the ground, the limiting structure 50 including a stop portion 52 for cooperating with the container 200 to stop the container 200 during cleaning, and the position of the stop portion 52 is adjustable.

[0112] In other words, the stop part 52 can position the container 200, so that the container 200 can remain in the same position during the cleaning process, and prevent the container 200 from slipping when impacted by water flow, which would cause the first nozzle 13 to fall off the container 200.

[0113] The position of the stop 52 is adjustable, allowing the limiting structure 50 to stop containers 200 of different sizes. For example, when cleaning a large container 200, the stop 52 is farther from directly below the first nozzle 13. When cleaning a small container 200, the stop 52 is closer to directly below the first nozzle 13. Furthermore, when the container 200 needs to be moved, the stop 52 can be adjusted to move out of the container 200's path, preventing obstruction of the container's movement.

[0114] In this application, the type of the limiting structure 50 can be selected in several ways.

[0115] For example, in some specific embodiments, the limiting structure 50 includes an electric push rod or a cylinder, and a stop 52 is connected to the moving end of the electric push rod or cylinder. When the container 200 needs to be positioned, the moving end of the electric push rod or cylinder extends, bringing the stop 52 closer to the container 200. The stop 52 can block the front or rear side of the container 200. When the container 200 needs to be moved, the moving end of the electric push rod or cylinder retracts, moving the stop 52 away from the container 200. The limiting structure 50 includes an electric push rod or a cylinder, allowing the action of the limiting structure 50 to be automatically executed after a signal is given, reducing the intensity of manual labor.

[0116] In other specific embodiments, such as Figure 3 As shown, the container cleaning device 10 also includes a limiting rail 51. The limiting rail 51 is disposed on the guide rail 30 and extends along the length of the guide rail 30. The limiting rail 51 has at least one limiting groove 511. A stop part 52 can be inserted into and pulled out of the limiting groove 511. The stop part 52 is used to block at least one side of the container 200 to position the container 200. This method requires manual handling of the stop part 52, which is low-cost and convenient for maintenance.

[0117] Specifically, the stop part 52 is very flexible in its use. For example, when there is no container 200, the stop part 52 can be pulled out from the limiting groove 511. When a container 200 is to be cleaned, the stop part 52 is inserted into the limiting groove 511 beforehand, and then the upper guide rail 30 of the container 200 is pushed and moved below the first nozzle 13 until the sliding member 203 of the container 200 abuts against the stop part 52, indicating that the container 200 is exactly below the first nozzle 13. At this time, the movement of the container 200 is stopped, and cleaning begins.

[0118] Alternatively, when a container 200 is to be cleaned, first push the container 200 onto the guide rail 30 and move it below the first nozzle 13. When the container 200 reaches below the first nozzle 13, insert the stop part 52 into the limiting groove 511. The stop part 52 blocks the container 200, and then the cleaning begins.

[0119] Furthermore, the limiting rail 51 is provided with a plurality of limiting grooves 511 spaced apart along the length direction, so that the stop part 52 can be inserted at a suitable position according to the size of the container 200.

[0120] Furthermore, within the guide groove 301 of the guide rail 30, a limiting rail 51 is provided on each side of the guide groove 301. Limiting grooves 511 are correspondingly provided on the two limiting rails 51 of the same guide groove 301. In use, the two ends of the stop part 52 are inserted into the limiting grooves 511 of the two limiting rails 51 within the same guide groove 301, thus stabilizing the stop part 52.

[0121] Of course, the guide rail 30 can also be omitted in this application. When the container 200 is equipped with a sliding member 203 at the bottom, and the sliding member 203 is a roller 2031, it can be moved directly along the ground to below the first nozzle 13. Alternatively, when the container 200 does not have a sliding member 203 at the bottom, workers can move the container 200 to below the first nozzle 13 using a handcart or similar means.

[0122] In this application, such as Figure 2 As shown, multiple first water supply pipes 12 can be provided. One end of each first water supply pipe 12 is connected to a water tank 11, and the other end is connected to a first nozzle 13. The first nozzles 13 can be arranged at intervals, for example, in a row, so that each nozzle 13 can clean one container 200, improving the cleaning capacity of the entire container cleaning device 10. Moreover, the water tank 11 is shared, reducing the number of parts. At this time, each first nozzle 13 can be turned on and off independently.

[0123] In this scheme, a water collection structure 16 is provided below each first nozzle 13, or a single water collection structure 16 can be used to collect all the sewage.

[0124] At this time, the container cleaning device 10 can also be equipped with one or more second water supply pipes 18 to connect to the second nozzles 19. When there is only one second nozzle 19, the exterior of multiple containers 200 can also be cleaned through the second water supply pipe 18.

[0125] According to the factory building 100 of this utility model embodiment, such as Figures 4-6 As shown, a container cleaning device 10 is installed inside the plant 100, or a container cleaning device 10 and a container drying device 20 are installed inside the plant 100. Figure 6 As shown, the container cleaning device 10 and the container drying device 20 are located in different areas within the plant 100. Or as... Figure 4 and Figure 5 As shown, the container cleaning device 10 and the container drying device 20 are located in the same area of ​​the plant 100.

[0126] The container cleaning device 10 is the container cleaning device 10 described in the above embodiment, and the structure of the container cleaning device 10 is not limited here.

[0127] In some solutions, such as Figure 5 As shown, the container cleaning device 10 and the container drying device 20 are located in the same area of ​​the factory building 100, and a partition 40 is provided between them. The partition 40 is provided to reduce water mist drifting from the container cleaning device 10 to the container drying device 20, thus reducing mutual interference. The partition 40 is movable and can be unfolded and retracted. The partition 40 can be a curtain or the like. Of course, the partition 40 may not be provided between the container cleaning device 10 and the container drying device 20 to increase the openness of the factory area's visual space.

[0128] Specifically, when a container cleaning device 10 and a container drying device 20 are installed, as two devices on a single work line, their quantities can be equal or unequal. For example... Figure 5 As shown, since the cleaning time is usually shorter than the drying time, the number of container cleaning devices 10 is less than the number of container drying devices 20. In some designs, the number of container drying devices 20 is twice the number of container cleaning devices 10.

[0129] Furthermore, when the container cleaning device 10 and the container drying device 20 are installed in the plant 100, they can share the guide rail 30, which will transfer the container 200 between different devices.

[0130] Optionally, such as Figure 4 As shown, the guide rail 30 includes a main rail 31. A main rail 31 is installed on the ground of the plant 100. Containers 200 enter different areas via the main rail 31, successively reaching the container cleaning device 10 and the container drying device 20. One end of the main rail 31 can extend outside the plant 100 or into the settling area.

[0131] Optionally, such as Figure 5 and Figure 6 As shown, the guide rail 30 includes a main rail 31 and branch rails 32, with at least two branch rails 32 extending to each device. A single main rail 31 may be provided to connect each branch rail 32.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0133] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
