Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to a pipeline cleaning device. Background Art

[0002] In the recycling process of waste batteries, the powder after the battery is crushed will first be pyrolyzed, and then screened to become very fine battery black powder. The battery black powder will then be transported to the dryer along the conveying pipeline. After a long period of transportation in the conveying pipeline, the battery black powder will adhere to the inner wall of the conveying pipeline, thereby increasing the friction of the inner wall of the conveying pipeline. The increased friction will affect the transmission speed of the black powder. In addition, because the components of the same battery are roughly the same, after a period of production, if other battery materials need to be replaced, the inner wall of the conveying pipeline needs to be painted and cleaned to ensure that different battery black powders will not mix.

[0003] When cleaning the conveying pipeline, for a section of the pipeline where the black powder is not too dry, a brush head is needed to clean it. However, the current pipeline cleaning equipment cannot systematically complete the cleaning work. For example, the dust inside the pipeline will not be recovered during the cleaning process, and the inner wall is not cleaned thoroughly. This will not only cause waste of battery powder, but also cause unnecessary pollution to the environment. In addition, the residual dust will affect the quality of subsequent products, especially some residual battery powder that falls off intermittently, which will affect the quality of subsequent long-term products. Therefore, it is necessary to clean the residual battery powder in the pipeline during cleaning. In addition, some pipeline cleaning equipment needs to be powered by wires, and some use batteries for power supply. Among them, wire power supply is prone to danger, and battery power supply is limited by the battery power. Sometimes, due to the long cleaning time and the difficulty in real-time power control according to the cleaning status during cleaning, the internal cleaning is not clean enough, which brings quality risks to subsequent products.

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "top", "bottom", etc. used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figure 1 As shown, a pipeline cleaning device according to a preferred embodiment of the present invention comprises a pipeline 1, a blower 2, a driving mechanism 3 and a cleaning mechanism 4. The cleaning mechanism 4 is used to clean the dust on the inner surface of the pipeline 1, wherein the cleaning mechanism 4 is driven by the driving mechanism 3 to realize an ascending action, and the cleaning mechanism 4 is driven by its own weight and the blowing of the blower 2 to realize a descending action in the pipeline 1.

[0027] like Figure 1 As shown in Figure 3, in this embodiment, the pipeline 1 is a pipeline between the battery black powder screen and the drying box, wherein an upper valve 11 is provided at one end of the pipeline 1 connected to the screen, and a lower valve 12 is provided at one end of the pipeline 1 connected to the drying box. The pipeline 1 is provided with an opening 13, and the opening 13 is arranged upward and located on a side close to the upper valve 11. The driving mechanism 3 is installed on the opening 13, and the blower 2 is installed on the driving mechanism 3. The air outlet 14 of the blower 2 is downward and toward the inside of the pipeline 1. When the blower 2 is started, the blower 2 blows high-pressure air into the pipeline 1. The driving mechanism 3 is located directly below the blower 2. The driving mechanism 3 includes a driver and a suspension rope 31. The driver includes a driving motor 32 and a reel 33. The suspension rope 31 is wound on the reel 33, and then pulled by a plurality of driven wheels and extends into the pipeline 1. The driver controls the rotation of the reel 33, thereby controlling the reel 31 to be retracted or released.

[0028] like Figure 1 As shown in Figure 5, the cleaning mechanism 4 includes a main body 41, a brush and at least three guide wheels 42. The main body 41 is connected to the end of the suspension rope 31 away from the driver, and the driver can lift the main body 41 by winding up the suspension rope 31. The brush is located below the main body 41 and abuts against the inner wall of the pipe 1. The brush can brush off the dust on the inner surface of the pipe 1. The guide wheels 42 are surrounded by the main body 41 and abut against the inner wall of the pipe 1. The guide wheels 42 can guide the main body 41. When the main body 41 rises or falls, the main body 41 is placed in the center of the pipe 1, so that the brush always abuts against the inner surface of the pipe 1.

[0029] The working process of the present invention is as follows: when it is necessary to brush off the dust on the inner surface of the pipe 1, the upper valve 11 and the lower valve 12 are closed, the driver slowly releases the hanging rope 31, the main body 41 gradually drops down under its own gravity and the blowing of the blower 2 as the hanging rope 31 is slowly released, and the brush also drops down accordingly, brushing the inner surface of the pipe 1 from top to bottom to brush off the dust attached to the pipe 1, and after the dust falls from the inner surface of the pipe 1, it is blown out of the pipe 1 driven by the high-pressure airflow of the blower 2, thereby cleaning the pipe 1. When it is necessary to retract the main body 41, it is only necessary to control the driver to reel in the hanging rope 31, so that the main body 41 and the brush can be recovered.

[0030] In summary, an embodiment of the present invention provides a pipe cleaning device, which installs a blower 2 in the opening 13, and uses the driver and the blower 2 to drive the brush to rise or fall. During the movement of the brush, there is no need for a live wire to connect the main body 41 to follow the movement, thereby ensuring the safety of electricity use. There is no need to install a battery on the main body 41, and the movement of the brush will not be limited by the battery power. The dust brushed off can be more easily discharged from the pipe 1 after being blown by the high-pressure airflow, thereby improving the cleaning effect.

[0031] like Figure 1 As shown in Figure 3, a wind collecting hood 21 is provided between the blower 2 and the driving mechanism 3. The wind collecting hood 21 is funnel-shaped. When the blower 2 blows air to the wind collecting hood 21, the air flow can be more concentrated in the pipe 1. An air outlet 14 is provided on the pipe 1. The air outlet 14 is provided with a collecting bag 15. The air outlet 14 is located on the side close to the lower valve 12. The dust blown away by the high-pressure airflow of the blower 2 on the inner surface of the pipe 1 can fall into the collecting bag 15, which is convenient for the staff to recycle the powder.

[0032] like Figure 1 As shown in Figure 5, the brush includes a rotating block 43 and bristles 44. The rotating block 43 can rotate relative to the main body 41. The rotating block 43 is in the shape of a circular plate. A plurality of ventilation holes 431 are provided on the rotating block 43, wherein more than 50% of the area of ​​the end surface of the rotating block 43 is provided with ventilation holes 431, ensuring that there is enough uniform wind to blow the dust falling from the inner surface of the pipe 1 out of the pipe 1. The bristles 44 are fixed on the rotating block 43 and distributed on the side of the rotating block 43 to form a ring of bristles 44. The bristles 44 are against the inner wall of the pipe 1, and the outer diameter of the bristles 44 is roughly equal to the inner diameter of the pipe 1, ensuring that the entire inner surface of the pipe 1 can be brushed when the brush descends.

[0033] like Figure 1As shown in FIG. 4, the cleaning mechanism 4 also includes an adjuster and at least three extension rods 45. In this embodiment, there are four extension rods 45, which are distributed in a square shape. The extension rods 45 correspond to the guide wheels 42 one by one. The four guide wheels 42 can ensure that the main body 41 is always supported in the center of the pipe 1. One end of the extension rod 45 is hinged to the main body 41, and the other end of the extension rod 45 is hinged to the guide wheel 42. The adjuster is located on the main body 41, and the adjuster drives the extension rod 45 to rotate around the main body 41. In actual use, the angle of downward rotation of the extension rod 45 can be controlled by adjusting the adjuster, thereby changing the horizontal distance from the guide wheel 42 to the main body 41, so as to adapt to pipes 1 with different inner diameters.

[0034] like Figure 1 As shown in Figure 6, the regulator includes an expansion seat 46 and a spring seat 47. The expansion seat 46 is installed on the main body 41. One end of the spring seat 47 is hinged to the expansion seat 46, and the other end of the spring seat 47 is hinged to the expansion rod 45. The spring seat 47 includes a cylinder, a spring and a slide bar. The spring is located in the cylinder. One end of the spring is connected to the cylinder, and the other end of the spring is connected to the slide bar. The end of the slide bar away from the spring is hinged to the expansion rod 45, and the end of the cylinder away from the expansion rod 45 is hinged to the expansion seat 46. When the regulator changes the angle of the expansion rod 45, the spring can use elastic force to fix the expansion rod 45 at a certain angle. In other embodiments, the spring seat 47 can be a telescopic cylinder, and the expansion seat 46 is fixed to the main body 41. The piston rod is retracted by the telescopic cylinder to change the rotation angle of the expansion rod 45. The regulator also includes a pull rod 48 and a lifting module 49. The lifting module 49 is installed on the main body 41. The bottom end of the pull rod 48 is installed on the lifting module 49. The lifting module 49 drives the pull rod 48 to rise and fall. The extension seat 46 is fixed to the top of the pull rod 48. The extension seat 46 can move up and down relative to the main body 41. When the pull rod 48 rises, the extension seat 46 moves upward and the extension rod 45 is lifted. When the pull rod 48 moves downward, the extension seat 46 moves downward and the extension rod 45 rotates downward. By controlling the rise and fall of the pull rod 48, the expansion and contraction of the extension rod 45 can be realized, so as to adapt to pipes 1 with different inner diameters.

[0035] like Figure 3As shown in Figure 7, in this embodiment, the lifting module 49 includes an adjusting ring 491, a sun gear 492 and two planetary gears 494. The bottom end of the pull rod 48 is provided with an external thread. The main body 41 is provided with two upper and lower adjusting plates 411 and two arc-shaped connecting plates 412. The two adjusting plates 411 are fixed to each other by two arc-shaped connecting plates 412. The adjusting ring 491 is sleeved on the outside of the two connecting plates 412, and the adjusting ring 491 is located between the two adjusting plates 411. The inner surface of the adjustment ring 491 is provided with a circle of teeth, the planetary gear 494 is rotatably mounted on the adjustment plate 411, the sun gear 492 is located between the two planetary gears 494, and the two planetary gears 494 are meshed with the sun gear 492, the planetary gear 494 passes through the gap between the two connecting plates 412 and meshes with the teeth, the sun gear 492 is provided with an adjustment hole 493, the adjustment hole 493 is located at the center of the sun gear 492, the inner surface of the adjustment hole 493 is provided with an internal thread, the external thread meshes with the internal thread, wherein the pull rod 48 can be made into a quadrangular prism shape, so that it is restricted by the main body 41 and cannot rotate, when the sun gear 492 rotates, the pull rod 48 can only rise or fall relative to the main body 41. In actual use, the staff can manually rotate the adjustment ring 491 to rotate the planetary gear 494, thereby driving the sun gear 492 to rotate, and then controlling the lifting and lowering of the pull rod 48, and the angle of the extension rod 45 can be changed simply and conveniently. In other embodiments, the lifting module 49 is a lifting cylinder, the piston rod of the lifting cylinder is connected to the pull rod 48, and the pull rod 48 is lifted and lowered by extending and retracting the piston rod of the lifting cylinder.

[0036] like Figure 3 As shown in Figure 5, the cleaning mechanism 4 also includes two regulators and at least six extension rods 45, each regulator controls the rotation of at least three extension rods 45, and the two regulators are located in the same vertical direction. In this embodiment, one of the regulators is located directly above the other regulator, and each regulator controls the rotation of four extension rods 45. By setting the upper and lower regulators, the main body 41 can be kept in the center when moving up and down, and will not flip over. It is more stable when moving up and down, thereby ensuring the dust cleaning effect.

[0037] like Figure 1 As shown in Figure 4, the cleaning mechanism 4 further includes a passive fan 5, which is rotatably mounted at the bottom end of the main body 41, for example, the passive fan 5 is mounted at the bottom end of the main body 41 through a bearing. The rotating block 43 is located below the passive fan 5 and is fixed to the passive fan 5. Driven by the high-pressure airflow of the blower 2, the passive fan 5 will also rotate, thereby driving the brush to rotate, so that it can clean the inner surface of the pipe 1 horizontally, thereby improving the cleaning effect of the inner surface of the pipe 1.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
