Description

A safety cleaning device for chemical drums Technical Field

[0001] This utility model relates to the field of cleaning devices, and in particular to a safety cleaning device for chemical drums. Background Technology

[0002] Chemical drum cleaning equipment is a complete set of equipment specifically designed to remove residues (such as chemicals, oil stains, etc.) from chemical containers. It typically includes a high-pressure spray system, an automated conveyor line, an ultrasonic generator, a liquid extraction device, and a matching cleaning agent supply module. It achieves efficient cleaning through technologies such as physical rinsing, chemical dissolution, or high-frequency vibration, ensuring that there are no residues or corrosion inside the drum, while also guaranteeing operational safety and environmental protection requirements.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN221715244U, a safety cleaning device for chemical drums is disclosed. It uses multiple roller brushes in conjunction with an adjustment mechanism to clean chemical drums with different apertures. However, in order to avoid leakage, many current chemical drums are made with a small aperture and large body structure. Such equipment is not ideal, and there are stubborn stains during the cleaning process. Simply increasing the cleaning time or cleaning pressure will affect the work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a safe cleaning device for chemical drums in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A safety cleaning device for chemical drums includes an auxiliary mechanism for installation and lifting, and a sealing mechanism for preventing splashes. The sealing mechanism is mounted on the auxiliary mechanism. The device also includes a cleaning mechanism for cleaning the drum and an adjustment mechanism for adjusting the cleaning state of the cleaning mechanism during the cleaning process. The cleaning mechanism is mounted on a top sealing plate of the sealing mechanism, and a power component is connected to the top of the cleaning mechanism.

[0007] The cleaning mechanism includes a rotating water inlet pipe and a cleaning pipe. Several sets of cleaning pipes are arranged from top to bottom on the rotating water inlet pipe. The cleaning pipes are connected to the rotating water inlet pipe through the adjustment mechanism. Each set of cleaning pipes is arranged in a circular array. The bottom of the rotating water inlet pipe is connected to a bottom suction pipe through a telescopic pipe. The telescopic pipe is connected to the return water pipe of the rotating water inlet pipe.

[0008] The adjustment mechanism includes a torque disc, a variable diameter water spray hole, and a water outlet. The torque disc is rotatably connected to the rotating water inlet pipe. The variable diameter water spray hole is formed inside the torque disc corresponding to the cleaning pipe. The water outlet is formed on the rotating water inlet pipe corresponding to the variable diameter water spray hole. The torque disc is provided with a torque component that adapts to resistance and assists in resetting. The two ends of the torque component are respectively fixed to the rotating water inlet pipe and the torque disc.

[0009] Preferably, the top of the rotating water inlet pipe is connected to a water inlet plate, the water inlet plate is fixed to the upper end of the side sealing plate of the sealing mechanism, and the water inlet of the water inlet plate is connected to a water supply mechanism.

[0010] Preferably, each set of the cleaning tubes has 8 tubes, the cleaning tubes are made of rubber, the cleaning tubes have several water spray holes formed on them, and the end of the cleaning tube away from the rotating water inlet tube is a solid ball head.

[0011] Preferably, the variable diameter water spray hole is a conical hole, and one end of the variable diameter water spray hole that mates with the water outlet hole is a small hole, while the other end that mates with the cleaning pipe is a large hole.

[0012] Preferably, when the torque disc is in its initial position, the opening size of the variable diameter water spray hole and the water outlet hole is 20% of the size of the water outlet hole, and when the torque disc is in its extreme torsional position, the opening size is 100% of the size of the water outlet hole.

[0013] Preferably, the torque component is a spiral spring.

[0014] Preferably, the bottom suction pipe has a triangular groove formed at the bottom, the bottom suction pipe is connected to the telescopic pipe by a thread, and the telescopic pipe is slidably connected to the return pipe by a sealing ring.

[0015] Compared with existing technologies, the beneficial effects are as follows:

[0016] 1. The flexible rotating water inlet pipe can adapt to chemical drums of different diameters, thus cleaning from the inside. Compared with the original method of simply rinsing with water, the friction of the rotating water inlet pipe can improve the cleaning effect on the inner wall of the drum.

[0017] 2. By using the adjustment mechanism in conjunction with the rotating water inlet pipe, when encountering stubborn stains during the cleaning process, the rotating water inlet pipe and the torsion plate will rotate in the opposite direction, increasing the water spray volume of the corresponding area. This hardens the rotating water inlet pipe while increasing the water spray volume, allowing for deep cleaning of different areas. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] As shown in Figures 1-7, a safety cleaning device for chemical drums includes an auxiliary mechanism 1 for installation and lifting, and a sealing mechanism 3 for preventing splashes. The sealing mechanism 3 is installed on the auxiliary mechanism 1. The device also includes a cleaning mechanism 4 for cleaning the drum and an adjusting mechanism 5 for adjusting the cleaning state of the cleaning mechanism 4 during the cleaning process. The cleaning mechanism 4 is installed on the top sealing plate 32 of the sealing mechanism 3, and a power component is connected to the top of the cleaning mechanism 4.

[0031] The cleaning mechanism 4 includes a rotating water inlet pipe 42 and a cleaning pipe 43. Several sets of cleaning pipes 43 are arranged from top to bottom on the rotating water inlet pipe 42. The cleaning pipes 43 are connected to the rotating water inlet pipe 42 through the adjusting mechanism 5. Each set of cleaning pipes 43 is arranged in a circular array. The bottom of the rotating water inlet pipe 42 is connected to a bottom suction pipe 44 through a telescopic pipe 45. The telescopic pipe 45 is connected to the return water pipe 46 of the rotating water inlet pipe 42.

[0032] The adjustment mechanism 5 includes a torque disk 51, a variable diameter water spray hole 52, and a water outlet 53. The torque disk 51 is rotatably connected to the rotating water inlet pipe 42. The variable diameter water spray hole 52 is formed inside the torque disk 51 corresponding to the cleaning pipe 43. The water outlet 53 is formed on the rotating water inlet pipe 42 corresponding to the variable diameter water spray hole 52. The torque disk 51 is equipped with a torque component 6 for adapting to resistance and assisting in resetting. The two ends of the torque component 6 are fixed to the rotating water inlet pipe 42 and the torque disk 51, respectively.

[0033] In this embodiment, a water inlet plate 41 is connected to the top of the rotating water inlet pipe 42. The water inlet plate 41 is fixed to the upper end of the side sealing plate 31 of the sealing mechanism 3. The water inlet of the water inlet plate 41 is connected to the water supply mechanism 2. In this solution, the water supply mechanism 2 is a conventional water supply component such as a water pipe and a water pump, so it is not shown in detail. Its main function is to spray water through the water inlet plate 41, the rotating water inlet pipe 42, and the cleaning pipe 43, and to recycle wastewater through the return water pipe 46.

[0034] In this embodiment, each set of cleaning pipes 43 is provided with 8 pipes. The cleaning pipes 43 are made of rubber and have several water spray holes formed on them. The end of the cleaning pipe 43 away from the rotating water inlet pipe 42 is a solid ball head. When the rotating water inlet pipe 42 drives the cleaning pipe 43 to rotate, the rotating water inlet pipe 42 and the solid ball head at one end are thrown out by centrifugal force, thereby cleaning the inner wall of the chemical drum. At the same time, in conjunction with water spraying, deep cleaning is performed.

[0035] In this embodiment, the variable diameter water spray hole 52 is a conical hole, and one end of the variable diameter water spray hole 52 that matches the water outlet hole 53 is a small hole, while the other end that matches the cleaning pipe 43 is a large hole.

[0036] In this embodiment, when the torque disc 51 is in its initial position, the opening size of the variable diameter spray hole 52 and the water outlet hole 53 is 20% of the size of the water outlet hole 53. When the torque disc 51 is in its extreme torsional position, the opening size is 100% of the size of the water outlet hole 53. When the opening becomes larger, the water flow increases, but the water flow capacity of the opening on the cleaning pipe 43 does not change. As a result, the water pressure will accumulate inside the cleaning pipe 43, thereby increasing the internal pressure of the cleaning pipe 43 and making the cleaning pipe 43 harder. The harder cleaning pipe 43 has a stronger cleaning effect on the inner wall of the chemical drum and makes it easier to remove stains.

[0037] In this embodiment, the torsion component 6 is a spiral spring.

[0038] In this embodiment, the bottom suction pipe 44 has a triangular groove formed at the bottom. The bottom suction pipe 44 is connected to the telescopic pipe 45 by a thread. The telescopic pipe 45 is slidably connected to the return pipe 46 by a sealing ring. The triangular groove is used to prevent wastewater from being unable to be recycled when it sinks to the bottom.

[0039] Working principle: When not started, the lifting seat on the lifting assembly 11 drives the top sealing plate 32, water inlet plate 41 and cleaning pipe 43 to sink into the chemical drum. At this time, since the cleaning pipe 43 is not filled with water, it is flexible and easy to insert into the drum. The side sealing plate 31 is closed and protected by the side sealing plate 31, top sealing plate 32 and bottom water collection tank 33. The bottom rotating assembly 13 on the base 12 can drive the bottom water collection tank 33 to rotate and adjust. The motor on the top of the rotating water inlet pipe 42 is started to drive the rotating water inlet pipe 42 and cleaning pipe 43 to rotate. At the same time, the water pump of the water supply mechanism 2 (not shown) provides cleaning water to the rotating water inlet pipe 42 and cleaning pipe 43. The cleaning pipe 43 is filled and expanded after being subjected to water pressure. Water is sprayed from the small holes on the cleaning pipe 43 and then swung by centrifugal force to clean the inner wall of the chemical drum.

[0040] During cleaning, if there are severe stains or adhesions on the inner wall of a certain area, the friction of the cleaning pipe 43 will increase. At this time, the cleaning pipe 43 and the torque disk 51 in the corresponding area will be subjected to reverse torque. The reverse torque will drive the torque disk 51 to rotate in the opposite direction of rotation. The corresponding positions of the water outlet 53 and the variable diameter spray hole 52 will change from 20% to 100% (the changes in Figures 6 and 7). When the water flow increases, but the small hole of the cleaning pipe 43 does not change, the internal pressure of the cleaning pipe 43 will increase. At this time, the relative hardness of the cleaning pipe 43 will become harder, and the friction with the inner wall of the chemical drum will increase, thus enhancing the effect of cleaning stubborn stains. After the stains are cleaned, the torque disk 51 is reset by the torque component 6, the cleaning pipe 43 becomes soft, and cleaning continues. The wastewater is drawn back from the bottom suction pipe 44.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
