Description

Technical Field

[0001] The present invention relates to the technical field of barrel cleaning equipment, and in particular to a refrigerated barrel cleaning equipment. Background Art

[0002] For sustainable development, oil and chemical drums are often recycled after their raw materials are used up. However, before recycling, a certain amount of raw material impurities often remain on the inner wall of the drum. If these raw material impurities are recycled with the drum, it will obviously cause pollution.

[0003] In order to solve the above problems, the barrel body needs to be cleaned before recycling. The conventional cleaning method is to rinse with clean water. However, due to the large area of ​​the inner wall of the barrel body, the clean water rinse often requires manual assistance, which is not only inefficient, but also considering that some raw materials are difficult to dissolve in water, they will still remain on the inner wall of the barrel body, and the cleaning effect cannot be guaranteed. Therefore, a new cleaning method for the barrel body is urgently needed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that conventional cleaning methods are not only inefficient but also cannot guarantee cleaning effects.

[0005] In order to solve the above problems, the present invention provides a refrigeration barrel cleaning device, comprising:

[0006] Feeding station, used to place the barrel;

[0007] The freezing station is provided with a freezing cylinder, the upper side of the freezing cylinder is provided with an opening for the barrel to be placed in, and liquid nitrogen is provided in the freezing cylinder;

[0008] The striking station is provided with a receiving cylinder, the upper side of which is provided with an opening for the barrel to fall into, and the lower side of which is provided with a bottom plate for receiving the barrel;

[0009] A cleaning station is provided with a cleaning component for reaching into the barrel and cleaning the inner wall of the barrel;

[0010] The transfer module is used to grab the barrel body of the feeding station and move it to the freezing station, the beating station and the cleaning station in sequence. The transfer module includes a flipping mechanism, which is used to flip the barrel body up and down after being processed in the freezing station.

[0011] When the barrel body needs to be cleaned, the above scheme uses the transfer module to grab the barrel body to be cleaned at the feeding station and transfer it to the freezing station with the barrel mouth facing upward. The barrel body is rapidly cooled down under the action of liquid nitrogen in the freezing cylinder, so that the impurities on the inner wall of the barrel are frozen and formed into a solidified state. Then the transfer module takes the barrel body out of the freezing cylinder and turns the barrel body over to a position with the barrel mouth facing downward and then transfers it to the striking station. The transfer module loosens the barrel body so that the barrel body falls into the receiving cylinder and collides with the bottom plate. At this time, the impurities on the inner wall of the barrel can fall off relative to the inner wall of the barrel due to their solidified properties after freezing. Then the transfer module grabs the barrel body in the receiving cylinder again and transfers it to the cleaning station, and the cleaning component further cleans the residual impurities on the inner wall of the barrel. Compared with the existing technology, the above scheme uses the liquid nitrogen in the freezing station to transform the impurities on the inner wall of the barrel from a liquid state to a solidified state, and then the receiving cylinder of the striking station receives the striking of the barrel body, so that the impurities in the solidified state can be quickly and completely separated from the barrel body. Compared with the conventional cleaning method of flushing with clean water, it is highly efficient and has a better impurity removal effect. Finally, the residual impurities on the inner wall of the barrel body are further cleaned by the cleaning station, ensuring a more thorough removal effect of the impurities in the barrel body. At the same time, the above scheme uses the striking method to achieve the separation of impurities from the inner wall of the barrel body. Compared with conventional impact, it has at least the following advantages: 1. After being frozen in the freezing station, the impurities in the barrel body are easily solidified together. Therefore, by striking the entire barrel body, it helps to make the solidified impurities on the inner wall of the barrel body fall off as a whole, that is, the impurities are separated from the barrel body more thoroughly; 2. The impurities in the barrel have inertia. When the barrel falls to the bottom plate of the receiving cylinder and stops, the impurities will continue to separate from the inner wall of the barrel due to inertia, thereby achieving a better separation effect of the impurities relative to the inner wall of the barrel; 3. Compared with the conventional method of knocking on the barrel, the barrel that adopts the dropping method will be impacted when it falls to the bottom plate of the receiving cylinder, that is, the impact on the barrel will be more comprehensive and more intense, which will help the impurities to separate from the inner wall of the barrel; 4. The dropping method relies on the gravity of the barrel itself, saving energy consumption.

[0012] In an improved solution, at least two check cylinders are arranged circumferentially at the upper end of the freezing cylinder, and the cylinder rods of the check cylinders are set toward the opening of the freezing cylinder, so that when the cylinder rods of the check cylinders are extended, they will be in the opening position of the freezing cylinder, thereby pressing the barrel mouth end of the barrel body in the freezing cylinder, offsetting the upward buoyancy exerted by the liquid nitrogen on the barrel body, so that the transfer module does not need to continuously apply pressure to the barrel body, and the posture of the barrel body in the freezing cylinder is more stable.

[0013] In an improved solution, a first cylindrical limit frame with a vertical axis is provided in the freezing cylinder, the side wall of the first limit frame is grid-shaped, the inner side of the first limit frame is for the barrel body to enter, and the inner diameter of the upper end of the first limit frame is larger than the inner diameter of the lower end, so that the first limit frame can realize vertical guidance of barrel bodies of different sizes, prevent the barrel body from overturning in the freezing cylinder, and help to improve the stability of the pressing effect of the check cylinder on the barrel body.

[0014] In an improved solution, at least two circumferentially arranged elastic buffers are provided on the upper side of the bottom plate, so that the elastic buffers can provide a certain cushioning effect on the falling barrel body, thereby preventing the barrel body from being damaged by a hard collision with the bottom plate.

[0015] In an improved solution, a second cylindrical limit frame with a vertical axis is provided in the receiving cylinder, the side wall of the second limit frame is grid-shaped, the inner side of the second limit frame is accessible to the barrel body, the inner diameter of the upper end of the second limit frame is larger than the inner diameter of the lower end, thereby achieving vertical guidance of barrel bodies of different sizes through the second limit frame, preventing the barrel body from overturning in the receiving cylinder, and ensuring that the barrel body can be accurately buffered by the elastic buffer.

[0016] In an improved solution, the transfer module includes a conveying component and a clamp, and the conveying component acts on the clamp to drive the clamp to move horizontally or vertically. The feeding station, freezing station, striking station and cleaning station are all located below the horizontal movement path of the clamp, so that the barrel body can be grasped and transported by cooperating with the clamp through the conveying component.

[0017] In an improved solution, the clamp includes a first clamp and a second clamp, and the conveying assembly includes a first three-axis translation platform and a second three-axis translation platform. The first clamp is driven by the first three-axis translation platform to achieve movement between the feeding station and the freezing station. The first clamp is used to clamp the barrel mouth end of the barrel body and ensure that the barrel mouth end is upward. The second clamp is driven by the second three-axis translation platform to achieve movement between the striking station and the cleaning station. The second clamp is used to clamp the barrel bottom end of the barrel body after being processed at the freezing station. The flipping mechanism is a flipping motor arranged on the second three-axis translation platform. The flipping motor acts on the second clamp and is used to drive the second clamp to flip up and down, so that the barrel body is transported from the feeding station to the freezing station by the first three-axis translation platform in cooperation with the first clamp, and then the barrel body is flipped up and down after being processed at the freezing station and then transported to the striking station and the cleaning station by the second three-axis translation platform in cooperation with the flipping motor and the second clamp, which is highly efficient.

[0018] In an improved solution, a vibrator is provided on the second clamp, which is used to abut against the barrel body and drive the barrel body to vibrate, so that the barrel body can be pre-vibrated by the vibrator before being dropped, so that the inner wall of the barrel body is partially separated from the impurities, and then when the barrel body is subsequently dropped, the impurities can fall off better relative to the inner wall of the barrel body.

[0019] In an improved solution, the cleaning component includes a collection basin, a rotating shaft connected to the collection basin with a vertical axis, a scraper connected to the upper end of the rotating shaft, and a rotating motor acting on the rotating shaft to drive the rotating shaft to rotate. The rotating shaft drives the brush to sweep the inner wall of the barrel body, thereby further removing the residual impurities on the inner wall of the barrel body, and the collection basin can collect the fallen impurities to avoid pollution.

[0020] In an improved solution, the cleaning component includes a collection basin, a rotating shaft connected to the collection basin with a vertical axis, and a rotating motor acting on the rotating shaft to drive the rotating shaft to rotate. An air path is provided in the rotating shaft, and an upper end of the rotating shaft is provided with an air blowing head connected to the air path. The air outlet of the air blowing head is arranged obliquely downward. The air path of the rotating shaft is used to supply air to the blowing head through an external blower, and the air blowing head can blow the inner wall of the barrel body as the rotating shaft rotates, thereby further removing residual impurities on the inner wall of the barrel body, and the collection basin can collect the fallen impurities to avoid pollution.

[0021] In an improved solution, the cleaning component includes a collection basin, a rotating shaft connected to the collection basin with a vertical axis, and a rotating motor acting on the rotating shaft to drive the rotating shaft to rotate. An air path is provided in the rotating shaft, and a suction head connected to the air path is provided at the upper end of the rotating shaft. A discharge port connected to the air path is provided at the lower end of the rotating shaft, so that the suction head is driven to rotate by the rotating shaft to suction impurities on the inner wall of the barrel, thereby further removing residual impurities on the inner wall of the barrel, and the impurities sucked in by the suction head are discharged from the discharge port into the collection basin through the air path for collection to avoid pollution.

[0043] It should be understood that the transfer module can be a six-axis robotic arm with a high degree of freedom, so as to realize the grasping, transportation and flipping of the barrel body; and in this embodiment, the transfer module includes a conveying component and a clamp, and the conveying component acts on the clamp to drive the clamp to move horizontally or vertically. The feeding station 1, the freezing station 2, the striking station 3 and the cleaning station 4 are all located below the horizontal movement path of the clamp, so that the barrel body can be grasped and transported by cooperating with the clamp through the conveying component.

[0044] Furthermore, the clamp includes a first clamp 51 and a second clamp 61, and the transport assembly includes a first three-axis translation platform 5 and a second three-axis translation platform 6. The first clamp 51 is driven by the first three-axis translation platform 5 to realize the movement between the feeding station 1 and the freezing station 2. The first clamp 51 is used to clamp the barrel mouth end of the barrel body and ensure that the barrel mouth end is upward. The second clamp 61 is driven by the second three-axis translation platform 6 to realize the movement between the striking station 3 and the cleaning station 4. The second clamp 61 is used to clamp the barrel body after being processed in the freezing station 2. At the bottom end of the barrel, the flipping mechanism is a flipping motor 62 arranged on the second three-axis translation platform 6. The flipping motor 62 acts on the second clamp 61 and is used to drive the second clamp 61 to flip up and down, so that the barrel body is transported from the feeding station 1 to the freezing station 2 through the first three-axis translation platform 5 in cooperation with the first clamp 51, and then the barrel body is flipped up and down after being processed in the freezing station 2 and then transported to the striking station 3 and the cleaning station 4 through the second three-axis translation platform 6 in cooperation with the flipping motor 62 and the second clamp 61, which is highly efficient.

The second clamp 61 is connected to the output end of the flip motor 62.

[0046] When the barrel body needs to be cleaned, the above scheme uses the transfer module to grab the barrel body to be cleaned from the feeding station 1 and transfer it to the freezing station 2 with the barrel mouth facing upward. The barrel body is rapidly cooled down under the action of liquid nitrogen in the freezing cylinder 21, so that the impurities on the inner wall of the barrel are frozen and formed into a solidified state. Then the transfer module takes the barrel body out of the freezing cylinder 21 and turns the barrel body over to a position with the barrel mouth facing downward and then transfers it to the striking station 3. The transfer module loosens the barrel body so that the barrel body falls into the receiving cylinder 31 and collides with the bottom plate 32. At this time, the impurities on the inner wall of the barrel can fall off relative to the inner wall of the barrel due to their solidified properties after freezing. Then the transfer module grabs the barrel body in the receiving cylinder 31 again and transfers it to the cleaning station 4, and the cleaning component further cleans the residual impurities on the inner wall of the barrel.

[0047] Compared with the prior art, the above scheme uses the liquid nitrogen in the freezing station 2 to convert the impurities on the inner wall of the barrel from a liquid state to a solidified state, and then receives the impact of the barrel body through the receiving cylinder 31 of the impact station 3, so that the impurities in the solidified state can be quickly and completely separated from the barrel body. Compared with the conventional cleaning method of flushing with clean water, it is more efficient and has a better impurity removal effect. Finally, the residual impurities on the inner wall of the barrel body are further cleaned by the cleaning station 4, ensuring a more thorough removal effect of the impurities in the barrel body. At the same time, the above scheme uses the impact method to achieve the separation of impurities from the inner wall of the barrel body. Compared with conventional impact, it has at least the following advantages: 1. After being frozen in the freezing station 2, the impurities in the barrel body are easily formed into a state of being solidified as a whole. Therefore, by impacting the entire barrel body, it is helpful to make the solidified impurities on the inner wall of the barrel body fall off as a whole, that is, the impurities are more completely separated from the barrel body; 2. The impurities in the barrel body have inertia. When the barrel body falls to the bottom plate 32 of the receiving cylinder 31 and stops, the impurities will continue to separate from the inner wall of the barrel body due to inertia, thereby achieving a better separation effect of the impurities relative to the inner wall of the barrel body; 3. Compared with the conventional method of knocking on the barrel body, when the barrel body using the dropping method falls to the bottom plate 32 of the receiving cylinder 31, the entire barrel body will be impacted, that is, the impact on the barrel body will be more comprehensive and more intense, which will help the impurities to separate from the inner wall of the barrel body; 4. The dropping method is achieved by the gravity of the barrel body itself, saving energy consumption.

[0049] Combine Figure 7 As shown, taking into account that there may be differences in the size specifications of the barrel body, this embodiment further sets a first cylindrical limit frame 23 with a vertical axis in the freezing cylinder 21. The side wall of the first limit frame 23 is grid-shaped, and the inner side of the first limit frame 23 can be entered by the barrel body. The inner diameter of the upper end of the first limit frame 23 is larger than the inner diameter of the lower end, so that the first limit frame 23 can realize the vertical guidance effect of barrel bodies of different sizes and specifications, prevent the barrel body from overturning in the freezing cylinder 21, and help to improve the stability of the pressing effect of the check cylinder 22 on the barrel body.

[0050] Combine Figure 4 and Figure 8 As shown, in this embodiment, at least two circumferentially arranged elastic buffers 34 may be provided on the upper side of the bottom plate 32 of the receiving cylinder 31. The elastic buffers 34 provide a certain degree of cushioning to the falling barrel, thereby preventing the barrel from being damaged by a hard collision with the bottom plate 32. The elastic buffers 34 are preferably rubber gaskets, or vertically arranged springs. When the barrel falls into the receiving cylinder 31, it will contact the rubber gaskets or springs, thereby providing a good cushioning effect on the barrel.

[0051] Furthermore, a second cylindrical limit frame 33 with a vertical axis is provided in the receiving cylinder 31. The side wall of the second limit frame 33 is grid-shaped, and the inner side of the second limit frame 33 is accessible to the barrel body. The inner diameter of the upper end of the second limit frame 33 is larger than the inner diameter of the lower end, so that the second limit frame 33 can vertically guide barrel bodies of different sizes, prevent the barrel body from overturning in the receiving cylinder 31, and ensure that the barrel body can be accurately buffered by the elastic buffer 34.

[0052] Combine Figure 4 As shown, as another improvement to the above embodiment, a vibrator 63 is provided on the second clamp 61, and the vibrator 63 is used to abut against the barrel body and drive the barrel body to vibrate, so that the barrel body can be pre-vibrated by the vibrator 63 before being dropped, so that the inner wall of the barrel body is partially separated from the impurities, and then when the barrel body is subsequently dropped, the impurities can fall off better relative to the inner wall of the barrel body.

The rotating shaft 42 drives the scraper to sweep the inner wall of the barrel, further removing residual impurities on the inner wall of the barrel, while the collection basin 41 can collect fallen impurities to prevent contamination. The scraper can take various forms, such as a brush 44, a scraper, a brush bar, etc., which are not limited to this.

An air path is provided in the rotating shaft 42, and an air blowing head (not shown in the figure) connected to the air path is provided at the upper end of the rotating shaft 42.
