Description

Technical Field

[0001] This utility model belongs to the technical field of raw material barrel cleaning equipment, specifically relating to a raw material barrel cleaning device. Background Technology

[0002] Raw material drums are mainly used for storing, transporting, and handling various raw materials, and are widely used in chemical, food, and pharmaceutical industries. Most raw material drums are made of plastic, and are generally called plastic raw material drums or rubber raw material drums. They are blow-molded using scientific formulas, resulting in a variety of colors and attractive appearances. They meet packaging performance standards in terms of acid and alkali resistance, corrosion resistance, leak prevention, colorfastness, and non-deformation, making them an ideal choice for long-distance transportation of chemical products. Currently, most raw material drums on the market are used to transport chemical raw materials. After use, most raw material drums can be cleaned and recycled.

[0003] Manual cleaning is extremely inefficient, and more importantly, residual chemicals on the surface of the raw material drums can be harmful to workers. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0034] like Figure 1-6 As shown, a raw material barrel 6 cleaning device includes a housing 1, a conveying mechanism 2 and a cleaning mechanism 3. The bottom of the housing 1 is open, and an openable and closable inlet 101 is provided on one side wall of the housing 1. An openable and closable outlet 102 is provided on the other side wall of the housing 1 opposite to the inlet 101. The conveying mechanism 2 and the cleaning mechanism 3 are both located inside the housing 1. The conveying mechanism 2 passes through the inlet 101 and the outlet 102.

[0035] The cleaning mechanism 3 includes an outer wall cleaning mechanism 302 and an inner wall cleaning mechanism 301, which are used to clean the outer and inner walls of the raw material barrel 6, respectively.

[0036] In this embodiment, for ease of description and clarity, the position of the output port 102 relative to the input port 101 is defined as the front. The raw material barrel 6 enters from the input port 101, is conveyed by the conveying mechanism 2, and is output from the output port 102 in front.

[0037] In practice, the conveying mechanism 2 is used to transport the raw material barrel 6 from the inlet 101 to the outlet 102. During this process, the outer wall cleaning mechanism 302 cleans the dirt on the outer wall of the raw material barrel 6, and the inner wall cleaning mechanism 301 cleans the dirt on the inner wall of the raw material barrel 6.

[0038] In this embodiment, the inner wall cleaning mechanism 301 includes a first rotating shaft 3011. Multiple movable plates 3031 are evenly arranged along the circumferential direction on the outer wall of the first rotating shaft 3011. A first brush 3012 is fixedly installed on each of the multiple movable plates 3031. The first brush 3012 cooperates with the inner wall of the raw material barrel 6. An expansion and contraction mechanism 303 is provided on the first rotating shaft 3011 to change the relative distance between the first rotating shaft 3011 and the movable plates 3031.

[0039] The first brush 3012 contacts the inner wall of the raw material barrel 6. The first rotating shaft 3011 rotates, causing the movable plate 3031 and the first brush 3012 to rotate relative to the raw material barrel 6, thus cleaning the dirt from the inner wall of the raw material barrel 6. The expansion and contraction mechanism 303 can change the relative distance between the first rotating shaft 3011 and the movable plate 3031 to meet the usage requirements of raw material barrels 6 with different inner diameters.

[0040] In this embodiment, the expansion and contraction mechanism 303 includes a sliding sleeve 3032, a lead screw 3033, and a guide plate 3033. The sliding sleeve 3032 is slidably engaged with the outer wall of the first rotating shaft 3011. The sliding sleeve 3032 and the movable plate 3031 are connected by two or more parallel connecting rods 3035 of equal length. One end of the connecting rod 3035 is hinged to the outer wall of the sliding sleeve 3032, and the other end of the connecting rod 3035 is hinged to the inner wall of the movable plate 3031.

[0041] The guide plate 3033 is fixedly connected to the outer wall of the first rotating shaft 3011. The guide plate 3033 is provided with a radial groove. One end of the movable plate 3031 is slidably engaged with the groove of the movable plate 3031. Specifically, the groove is a dovetail groove structure or a T-shaped groove structure, which not only limits the movement trajectory of the movable plate 3031, but also provides force support for the movable plate 3031.

[0042] Multiple parallel connecting rods 3035 of equal length ensure that the movable plate 3031 and the sliding sleeve 3032 remain parallel at all times. Figure 3 As shown, when the sliding sleeve 3032 moves upward, it causes multiple movable plates 3031 to expand outward synchronously, increasing the distance between the movable plates 3031 and the first rotating shaft 3011, thus enabling the cleaning of the large-diameter raw material barrel 6. When the sliding sleeve 3032 moves downward, the multiple movable plates 3031 contract inward synchronously, decreasing the distance between the movable plates and the first rotating shaft 3011, thus enabling the cleaning of the small-sized raw material barrel 6.

[0043] The top end of the first rotating shaft 3011 is provided with a limiting groove that extends radially and axially. The top end of the sliding sleeve 3032 is fixedly connected to a connecting arm 3036 arranged radially. The connecting arm 3036 is slidably engaged with the limiting groove. The first rotating shaft 3011 is rotatably connected with a lead screw 3033. The lead screw 3033 is threadedly connected to the middle part of the connecting arm 3036.

[0044] The lead screw 3033 drives the connecting arm 3036 and the sliding sleeve 3032 to slide along the limiting groove. The limiting groove is used to limit the movement trajectory of the connecting arm 3036 and the sliding sleeve 3032, and the lead screw 3033 is used to transmit power. To ensure the mechanical strength of the connecting arm 3036, more than one connecting arm 3036 can be provided along the circumferential direction, and a limiting groove that cooperates with the connecting arm 3036 is provided at the top of the first rotating shaft 3011. Multiple connecting arms 3036 are integrally formed. In specific use, a drive motor is fixedly installed at the top of the first rotating shaft 3011, and the output end of the drive motor is fixedly connected to the lead screw 3033. The drive motor is used to drive the lead screw 3033 to rotate.

[0045] In this embodiment, the inner wall cleaning mechanism 301 includes a first rotating shaft 3011, a first brush 3012 is fixedly installed on the outer wall of the first rotating shaft 3011, the first rotating shaft 3011 and the first brush 3012 cooperate with the inner wall of the raw material barrel 6, and the first rotating shaft 3011 is connected to a height adjustment mechanism.

[0046] The height adjustment mechanism is used to adjust the height position of the first rotating shaft 3011 so that the first rotating shaft 3011 can extend into or out of the raw material barrel 6.

[0047] In this embodiment, the height adjustment mechanism includes a vertically arranged lifting frame 3013, an mounting plate 3014 slidably mounted on the lifting frame 3013, a first cleaning motor 3015 fixedly mounted on the mounting plate 3014, and the output end of the first cleaning motor 3015 fixedly connected to one end of the first rotating shaft 3011.

[0048] The lifting frame 3013 is equipped with a hydraulic cylinder 3016. The output end of the hydraulic cylinder 3016 is connected to the mounting plate 3014, and the other end of the hydraulic cylinder 3016 is fixedly connected to the bottom of the lifting frame 3013.

[0049] The hydraulic cylinder 3016 extends, causing the mounting plate 3014 to move upward along the lifting frame 3013, which in turn causes the first cleaning motor 3015 and the first rotating shaft 3011 to move upward until the first rotating shaft 3011 extends into the interior of the raw material barrel 6. The first cleaning motor 3015 drives the first rotating shaft 3011 to rotate, thus cleaning the interior of the raw material barrel 6. The hydraulic cylinder 3016 retracts, causing the first cleaning motor 3015 and the first rotating shaft 3011 to move downward until the first rotating shaft 3011 is removed from the interior of the raw material barrel 6.

[0050] In this embodiment, the outer wall cleaning mechanism 302 includes a second rotating shaft 3021, which is driven to rotate by a second cleaning motor 3023. A second brush 3022 is fixedly connected to the side wall of the second rotating shaft 3021. The second rotating shaft 3021 is connected to a position adjustment mechanism 4, which is used to change the relative position of the second rotating shaft 3021 and the raw material barrel 6 to adapt to the usage requirements of raw material barrels 6 of different sizes.

[0051] The outer wall cleaning mechanism 302 is used to clean the outer surface of the raw material barrel 6. The position adjustment mechanism 4 drives the second rotating shaft 3021 to move closer to or further away from the raw material barrel 6 so that raw material barrels 6 of different sizes can be cleaned, which greatly improves the versatility of this embodiment.

[0052] In this embodiment, the position adjustment mechanism 4 includes a base 401 fixedly disposed at both ends of the second rotating shaft 3021, a roller 402 rotatably disposed on the base 401, and a guide rail 403 fixedly disposed at the bottom and top of the housing 1. The extension direction of the guide rail 403 is perpendicular to the conveying direction of the conveying mechanism 2, and the roller 402 and the guide rail 403 are in rolling cooperation.

[0053] The top of the housing 1 is provided with a first cylinder 404. The output end of the first cylinder 404 is connected to the base 401 located on the top of the housing 1, and the other end of the first cylinder 404 is fixedly connected to the housing 1.

[0054] The first cylinder 404 extends and retracts, pushing the base 401 to move along the guide rail 403. The roller 402 reduces the friction between the base 401 and the guide rail 403 and improves the stability of the base 401's movement. Specifically, when the first cylinder 404 extends, the second rotating shaft 3021 moves closer to the raw material barrel 6, allowing for cleaning of the raw material barrel 6 with a smaller outer diameter. When the first cylinder 404 retracts, the second rotating shaft 3021 moves away from the raw material barrel 6, allowing for cleaning of the raw material barrel 6 with a larger outer diameter.

[0055] The outer wall cleaning mechanism 302 also includes a water tank 304 located outside the housing 1. A water pump 305 is connected to the bottom of the water tank 304. The interior of the second rotating shaft 3021 is a hollow structure. Multiple water outlet holes are provided through the circumferential side wall of the second rotating shaft 3021. The second rotating shaft 3021 is rotatably sealed to the water pump 305, so as to achieve sealing without affecting the rotation of the second rotating shaft 3021.

[0056] The water tank 304 contains cleaning agent. The water pump 305 pumps the cleaning agent in the water tank 304 into the first rotating shaft 3011 or the second rotating shaft 3021, and sprays it evenly onto the inner wall or outer surface of the raw material barrel 6 through the water outlet on the outer wall of the first rotating shaft 3011 or the second rotating shaft 3021 to enhance the cleaning effect.

[0057] In practice, a wastewater collection device can be installed at the bottom of the casing 1 to collect and purify the wastewater generated during the cleaning process, which can then be reused for cleaning. This not only saves water resources but also prevents harmful chemicals on the surface of the raw material barrel 6 from polluting the environment.

[0058] To prevent cleaning agents from causing circuit malfunctions or corroding related components, conventional and effective waterproofing measures, such as installing protective covers on relevant wiring and electrical components, should be taken in practical applications. In this embodiment, to illustrate the internal structure of the casing 1, the relevant waterproofing facilities are not shown in the accompanying drawings.

[0059] In this embodiment, the conveying mechanism 2 includes a roller conveyor line 201, on which a lifting mechanism is provided. The lifting mechanism has a second cylinder, and a base plate is fixedly installed at the output end of the second cylinder. The base plate cooperates with the open end of the raw material barrel 6. Specifically, the base plate has a through hole, and the opening of the raw material barrel 6 is upside down on the base plate. The first rotating shaft 3011 passes through the through hole, penetrates the base plate, and extends into or out of the raw material barrel 6.

[0060] It should be noted that the roller conveyor 201 in this embodiment is a conventional technology in the prior art, and its structure and working principle will not be described in detail. In the non-working state, the upper surface of the base plate is lower than the conveying surface of the roller conveyor 201. The second cylinder extends, driving the base plate upwards. After the upper surface of the base plate abuts against the open end of the raw material barrel 6, the raw material barrel 6 is gradually lifted. At this time, the bottom surface of the raw material barrel 6 is no longer in contact with the roller conveyor 201, and therefore the raw material barrel 6 no longer moves forward with the operation of the roller conveyor 201, preparing for the next step of thoroughly cleaning the surface of the raw material barrel 6. In specific implementation, a high-pressure spray gun is installed below the base plate. The high-pressure spray gun is connected to the water pump 305 through a pipeline. The high-pressure spray gun sprays cleaning agent onto the inner wall of the raw material barrel 6, improving the cleaning effect and speed.

[0061] In practice, clearance areas are provided at the positions on the roller conveyor line 201 corresponding to the path of the second rotating shaft 3021 and at the position of the base plate to prevent interference between the second rotating shaft 3021, the base plate and the roller conveyor line 201.

[0062] In this embodiment, columns 5 are vertically fixed on both sides of the roller conveyor line 201. A sleeve 501 is rotatably connected to the side wall of the column 5. An mounting bracket 502 is fixed on the outer side wall of the sleeve 501. A pulley 503 is rotatably mounted on the mounting bracket 502. The pulley 503 is detachably rolled with the outer side wall of the raw material barrel 6.

[0063] Specifically, the pulleys 503 located on both sides of the roller conveyor line 201 abut against the side wall of the raw material barrel 6, providing support for the raw material barrel 6 and preventing it from tipping over during the washing process.

[0064] In this embodiment, the mounting bracket 502 is an I-shaped frame structure consisting of a vertical frame 5022 and a horizontal frame 5021 that is vertically fixed to both ends of the vertical frame 5022. The vertical frame 5022 is fixedly connected to the outer wall of the sleeve 501, and pulleys 503 are rotatably connected to both ends of the horizontal frame 5021.

[0065] The sleeve 501 drives the mounting bracket 502 to rotate, thereby controlling the pulley 503 to contact or separate from the raw material barrel 6. During the cleaning process, the rotation of the second rotating shaft 3021 and the second brush 3022 causes the raw material barrel 6 to rotate relative to the pulley 503, allowing the cleaning mechanism 3 to clean different parts of the side wall of the raw material barrel 6. Moreover, the rolling contact between the pulley 503 and the outer wall of the raw material barrel 6 can also prevent scratches on the surface of the raw material barrel 6.

[0066] A third cylinder 504 is provided between the sleeve 501 and the inner wall of the housing 1. The output end of the third cylinder 504 is rotatably connected to the outer wall of the sleeve 501, and the other end of the third cylinder 504 is rotatably connected to the inner wall of the housing 1.

[0067] The third cylinder 504 extends, causing the mounting bracket 502 to rotate clockwise, and the pulley 503 abuts against the outer surface of the raw material barrel 6. The second cylinder retracts, causing the mounting bracket 502 to rotate counterclockwise, and the pulley 503 separates from the outer surface of the raw material barrel 6.

[0068] In this embodiment, vertical slide rails are fixedly installed on both sides of the input port 101 and the output port 102 of the housing 1. A slide block is slidably provided on the slide rail, and a protective door 103 is fixedly connected to the slide block. A fourth cylinder 104 is provided outside the housing 1. The output end of the fourth cylinder 104 is fixedly connected to the outer surface of the protective door 103, and the other end of the fourth cylinder 104 is fixedly connected to the bottom of the housing 1.

[0069] The fourth cylinder 104 extends, causing the protective door 103 to move upward along the slide rail. The fourth cylinder 104 retracts, causing the protective door 103 to move downward along the slide rail. The protective door 103 is used to control the opening and closing of the inlet 101 and the outlet 102 to prevent liquid containing chemical reagents from splashing outside the housing 1 during the cleaning process.

[0070] In this embodiment, cleaning agent is first poured into the water tank 304. The raw material barrel 6 to be cleaned is then placed with its opening facing down onto the roller conveyor line 201 of the inlet 101. As the roller conveyor line 201 moves the raw material barrel 6 forward, the cleaning mechanism 3 cleans the surface of the raw material barrel 6. Specifically, the second cylinder extends, moving the raw material barrel 6 upward, thereby lifting it up and causing the bottom surface of the raw material barrel 6 to disengage from the surface of the roller conveyor line, thus preventing the raw material barrel 6 from moving forward with the roller conveyor line 201. The third cylinder 504 extends, rotating the mounting bracket 502. The mounting brackets 502 and pulleys 503 on both sides of the roller conveyor line 201 clamp the raw material barrel 6, preventing it from tipping over.

[0071] The second cleaning motor 3023 drives the second rotating shaft 3021 and the second brush 3022 to rotate. Simultaneously, the water pump 305 pumps cleaning agent into the first rotating shaft 3011 and the second rotating shaft 3021, and sprays it outwards through spray nozzles onto the inner wall and outer surface of the raw material barrel 6. The first cleaning motor 3015 drives the first rotating shaft 3011 and the first brush 3012 to rotate, cleaning the inner wall of the raw material barrel 6. The second cleaning motor 3023 drives the second rotating shaft 3021 and the second brush 3022 to rotate, cleaning the surface of the raw material barrel 6.

[0072] The relative distance between the second rotating shaft 3021 and the raw material barrel 6 can also be adjusted by the position adjustment mechanism 4 to accommodate the cleaning requirements of raw material barrels 6 with different outer diameters. Specifically, when the first cylinder 404 extends, the second rotating shaft 3021 moves closer to the raw material barrel 6, which can clean raw material barrels 6 with smaller outer diameters. When the first cylinder 404 retracts, the second rotating shaft 3021 moves away from the raw material barrel 6, which can clean raw material barrels 6 with larger outer diameters.

[0073] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
