Description

Technical Field

[0001] The present invention relates to the technical field of barrel cleaning equipment, and particularly to a freeze-type barrel cleaning equipment. Background Art

[0002] Due to the need for sustainable development, barrels such as oil barrels and chemical barrels will be recycled after the internal raw materials are exhausted. Before recycling, a certain amount of raw material impurities often remain on the inner wall of the barrel. If these raw material impurities are recycled together with the barrel, it will obviously cause pollution.

[0003] To solve the above problems, the barrel needs to be cleaned before recycling. The conventional cleaning method is to rinse with clean water. However, due to the large inner wall area of the barrel, manual assistance is often required for clean water rinsing, which not only has low efficiency, but also considering that some raw materials are insoluble in water and will still remain on the inner wall of the barrel, the cleaning effect cannot be guaranteed. Therefore, there is an urgent need for a new cleaning method for barrels. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that the conventional cleaning method not only has low efficiency, but also cannot guarantee the cleaning effect.

[0005] To solve the above problems, the present invention provides a freeze-type barrel cleaning equipment, including: A feeding station for placing the barrel; A freezing station provided with a freezing cylinder. An opening for the barrel to be placed is provided on the upper side of the freezing cylinder, and liquid nitrogen is provided in the freezing cylinder; A dropping station provided with a receiving cylinder. An opening for the barrel to fall into is provided on the upper side of the receiving cylinder, and a bottom plate for receiving the barrel is provided on the lower side of the receiving cylinder; A cleaning station provided with a cleaning component for extending into the barrel and cleaning the inner wall of the barrel; A transfer module for grasping the barrel at the feeding station and sequentially moving it to the freezing station, the dropping station and the cleaning station. The transfer module includes a flipping mechanism for flipping the barrel upside down after being processed at the freezing station.

[0006] When the barrel needs to be cleaned, the above solution uses the transfer module to grab the barrel to be cleaned at the feeding station and transfer it to the freezing station with the barrel mouth facing up. The barrel is quickly cooled under the action of liquid nitrogen in the freezing cylinder, so that the impurities on the inner wall of the barrel are frozen into a solidified state. Then the transfer module takes the barrel out of the freezing cylinder and turns the barrel to the posture with the barrel mouth facing down, and then transfers it to the impact station. The transfer module releases the barrel so that the barrel falls into the receiving cylinder and impacts 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 because they are in a solidified state after freezing. Then the transfer module grabs the barrel 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 prior art, the above solution changes the impurities on the inner wall of the barrel from a liquid state to a solidified state by the liquid nitrogen at the freezing station, and then the receiving cylinder at the impact station receives the impact of the barrel, so that the solidified impurities can quickly and completely separate from the barrel. Compared with the conventional cleaning method of rinsing with clean water, the efficiency is high and the removal effect of impurities is better. Finally, the residual impurities on the inner wall of the barrel are further cleaned at the cleaning station to ensure a more thorough cleaning effect on the impurities in the barrel. At the same time, the above solution uses the impact method to realize the separation of impurities relative to the inner wall of the barrel. Compared with the conventional impact, it has at least the following advantages: 1. After the impurities in the barrel are frozen at the freezing station, they are easily formed into a state of being solidified together as a whole. Therefore, by impacting the whole barrel, it helps the impurities solidified together on the inner wall of the barrel to fall off as a whole, that is, the separation of impurities relative to the barrel is more thorough. 2. The impurities in the barrel have inertia. When the barrel stops when it falls on the bottom plate of the receiving cylinder, the impurities will continue to separate from the inner wall of the barrel due to inertia, achieving a better separation effect of impurities relative to the inner wall of the barrel. 3. Compared with the conventional method of knocking on the barrel, when the barrel using the impact method falls on the bottom plate of the receiving cylinder, the whole barrel will be impacted, that is, the impact force on the barrel will be more comprehensive and intense, which helps the separation of impurities relative to the inner wall of the barrel. 4. The impact method is realized by the gravity of the barrel itself, saving energy consumption.

[0007] In an improved solution, at least two check cylinders are arranged circumferentially at the upper end of the freezing cylinder. The cylinder rods of the check cylinders face the opening of the freezing cylinder. Thus, when the cylinder rods of the check cylinders extend, they will be at the opening position of the freezing cylinder to press the barrel mouth end of the barrel in the freezing cylinder, offset the upward buoyancy exerted by the liquid nitrogen on the barrel, so that the transfer module does not need to continuously press the barrel, and the posture of the barrel in the freezing cylinder is more stable.

[0008] In an improved solution, a cylindrical first limiting frame with a vertical axis is provided inside the freezing cylinder. The side wall of the first limiting frame is grid-shaped. The inside of the first limiting frame allows the barrel body to enter. The inner diameter of the upper end of the first limiting frame is larger than that of the lower end. Thus, the first limiting frame realizes the vertical guiding function for barrel bodies of different sizes and specifications, prevents the problem of the barrel body tipping over in the freezing cylinder, and helps to improve the stability of the pressing action of the check cylinder on the barrel body.

[0009] In an improved solution, at least two elastic buffer members arranged circumferentially are provided on the upper side of the bottom plate. Thus, the elastic buffer members buffer the falling barrel body to avoid the barrel body being damaged due to hard impact with the bottom plate.

[0010] In an improved solution, a cylindrical second limiting frame with a vertical axis is provided inside the receiving cylinder. The side wall of the second limiting frame is grid-shaped. The inside of the second limiting frame allows the barrel body to enter. The inner diameter of the upper end of the second limiting frame is larger than that of the lower end. Thus, the second limiting frame realizes the vertical guiding function for barrel bodies of different sizes and specifications, prevents the problem of the barrel body tipping over in the receiving cylinder, and can ensure that the barrel body can be accurately buffered by the elastic buffer members.

[0011] In an improved solution, the transfer module includes a conveying component and a gripper. The conveying component acts on the gripper to drive the gripper to move horizontally or vertically. The feeding station, freezing station, impact station, and cleaning station are all located below the horizontal movement path of the gripper. Thus, the conveying component cooperates with the gripper to realize the grasping and conveying of the barrel body.

[0012] In an improved solution, the gripper includes a first gripper and a second gripper. The conveying component includes a first three-axis displacement table and a second three-axis displacement table. The first gripper is driven by the first three-axis displacement table to move between the feeding station and the freezing station. The first gripper is used to grip the mouth end of the barrel body and ensure that the mouth end is upward. The second gripper is driven by the second three-axis displacement table to move between the impact station and the cleaning station. The second gripper is used to grip the 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 displacement table. The flipping motor acts on the second gripper and is used to drive the second gripper to flip up and down. Thus, the first three-axis displacement table cooperates with the first gripper to realize the conveyance of the barrel body from the feeding station to the freezing station, and then the second three-axis displacement table cooperates with the flipping motor and the second gripper to realize the conveyance of the barrel body after being processed at the freezing station, flipping up and down, and then to the impact station and the cleaning station, with high efficiency.

[0013] In an improved solution, a vibrator is provided on the second jaw. The vibrator is used to abut against the barrel and drive the barrel to vibrate. Thus, before the barrel is subjected to impact, the vibrator can pre-vibrate the barrel in advance, so that the inner wall of the barrel is partially separated from the impurities. Then, when the barrel is subjected to impact subsequently, the impurities can better fall off relative to the inner wall of the barrel.

[0014] In an improved solution, the cleaning assembly includes an aggregate basin, a rotating shaft rotatably connected to the aggregate basin with the vertical axis, a brush cleaner 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. Thus, the brush is driven by the rotating shaft to brush the inner wall of the barrel, realizing further removal of the residual impurities on the inner wall of the barrel. The aggregate basin can collect the fallen impurities to avoid contamination.

[0015] In an improved solution, the cleaning assembly includes an aggregate basin, a rotating shaft rotatably connected to the aggregate basin with the vertical axis, and a rotating motor acting on the rotating shaft to drive the rotating shaft to rotate. An air passage is provided in the rotating shaft, and a blowing head communicating with the air passage is provided at the upper end of the rotating shaft. The air outlet of the blowing head is arranged obliquely downward. The air passage of the rotating shaft supplies air to the blowing head through an external blower. The blowing head can rotate with the rotating shaft to blow the inner wall of the barrel, realizing further removal of the residual impurities on the inner wall of the barrel. The aggregate basin can collect the fallen impurities to avoid contamination.

[0016] In an improved solution, the cleaning assembly includes an aggregate basin, a rotating shaft rotatably connected to the aggregate basin with the vertical axis, and a rotating motor acting on the rotating shaft to drive the rotating shaft to rotate. An air passage is provided in the rotating shaft, and a suction head communicating with the air passage is provided at the upper end of the rotating shaft. A discharge port communicating with the air passage is provided at the lower end of the rotating shaft. Thus, the suction head is driven by the rotating shaft to rotate to suck the impurities on the inner wall of the barrel, realizing further removal of the residual impurities on the inner wall of the barrel. The impurities sucked by the suction head are discharged into the aggregate basin through the air passage from the discharge port for collection to avoid contamination. Description of the Drawings

[0024] It should be understood that the transfer module can be a six-axis robotic arm with a high degree of freedom to achieve the grasping, transportation, and flipping of the barrel. In this embodiment, the transfer module includes a transportation component and a gripper. The transportation component acts on the gripper to drive the gripper to move horizontally or vertically. The feeding station 1, the freezing station 2, the dropping station 3, and the cleaning station 4 are all located below the horizontal movement path of the gripper, so as to realize the grasping and transportation of the barrel through the cooperation of the transportation component and the gripper.

[0025] Further, the gripper includes a first gripper 51 and a second gripper 61. The transportation component includes a first three-axis displacement stage 5 and a second three-axis displacement stage 6. The first gripper 51 is driven by the first three-axis displacement stage 5 to move between the feeding station 1 and the freezing station 2. The first gripper 51 is used to clamp the mouth end of the barrel and ensure that the mouth end is upward. The second gripper 61 is driven by the second three-axis displacement stage 6 to move between the dropping station 3 and the cleaning station 4. The second gripper 61 is used to clamp the bottom end of the barrel after being processed at the freezing station 2. The flipping mechanism is a flipping motor 62 arranged on the second three-axis displacement stage 6. The flipping motor 62 acts on the second gripper 61 and is used to drive the second gripper 61 to flip upside down, so as to realize the transportation of the barrel from the feeding station 1 to the freezing station 2 through the cooperation of the first three-axis displacement stage 5 and the first gripper 51, and then realize the transportation of the barrel after being processed at the freezing station 2, flipping upside down, and then to the dropping station 3 and the cleaning station 4 through the cooperation of the second three-axis displacement stage 6, the flipping motor 62, and the second gripper 61, with high efficiency.

[0026] The first three-axis displacement stage 5 and the second three-axis displacement stage 6 are both prior arts. Specifically, the first three-axis displacement stage 5 includes a first X-axis guide rail arranged in the front-back direction, a first Y-axis guide rail arranged in the left-right direction, and a first Z-axis guide rail arranged in the up-down direction.

The second jaw 61 is connected to the output end of the flipping motor 62.

[0027] When it is necessary to clean the barrel body, the above solution grabs the barrel body to be cleaned at the feeding station 1 through the transfer module and transfers it to the freezing station 2 with the barrel mouth end facing up. The barrel body is quickly cooled under the action of liquid nitrogen in the freezing cylinder 21, so that the impurities on the inner wall of the barrel body are frozen into a consolidated state. Then the transfer module takes out the barrel body from the freezing cylinder 21 and flips the barrel body to the posture with the barrel mouth end facing down and then transfers it to the impact station 3. The transfer module releases the barrel body so that the barrel body falls into the receiving cylinder 31 and impacts the bottom plate 32. At this time, the impurities on the inner wall of the barrel body can fall off relative to the inner wall of the barrel body because they are in a frozen and consolidated state. 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 body.

[0028] Compared with the prior art, in the above solution, the liquid nitrogen in the freezing station 2 converts the impurities on the inner wall of the barrel from a liquid state to a solidified state, and then the receiving cylinder 31 in the impact station 3 receives the impact of the barrel, so that the solidified impurities can quickly and completely separate from the barrel, which is more efficient and has a better impurity removal effect compared with the conventional cleaning method of rinsing with clean water. Finally, the cleaning station 4 further cleans the residual impurities on the inner wall of the barrel to ensure a more thorough cleaning effect on the impurities in the barrel. At the same time, the above solution uses the impact method to achieve the separation of impurities from the inner wall of the barrel. Compared with the conventional impact, it has at least the following advantages: 1. After the impurities in the barrel are frozen in the freezing station 2, they are easily formed into a state of being solidified together as a whole. Therefore, by impacting the entire barrel, it helps the impurities solidified together on the inner wall of the barrel to fall off as a whole, that is, the separation of impurities from the barrel is more thorough; 2. The impurities in the barrel have inertia. When the barrel stops when it falls onto the bottom plate 32 of the receiving cylinder 31, the impurities will continue to separate from the inner wall of the barrel due to inertia, achieving a better separation effect of impurities from the inner wall of the barrel; 3. Compared with the conventional method of knocking on the barrel, when the barrel using the impact method falls onto the bottom plate 32 of the receiving cylinder 31, the entire barrel will be impacted, that is, the impact force on the barrel will be more comprehensive and intense, which helps the separation of impurities from the inner wall of the barrel; 4. The impact method is achieved by the gravity of the barrel itself, saving energy consumption.

[0029] Combined with Figure 1 and Figure 3 As shown, as an improved solution to the above embodiment, at least two check cylinders 22 are arranged circumferentially along the upper end of the freezing cylinder 21. The cylinder rod of the check cylinder 22 is arranged towards the opening of the freezing cylinder 21, so that when the cylinder rod of the check cylinder 22 extends, it can be in the opening position of the freezing cylinder 21 to press the mouth end of the barrel in the freezing cylinder 21, offset the upward buoyancy exerted on the barrel by the liquid nitrogen, so that the transfer module does not need to continuously press the barrel, and the posture of the barrel in the freezing cylinder 21 is more stable.

[0030] Combined with Figure 7 As shown, considering that there may be differences in the size specifications of the barrels, in this embodiment, a cylindrical first limiting frame 23 with a vertical axis is further arranged in the freezing cylinder 21. The side wall of the first limiting frame 23 is grid-shaped. The inside of the first limiting frame 23 is available for the barrel to enter. The inner diameter of the upper end of the first limiting frame 23 is larger than the inner diameter of the lower end. Thus, the first limiting frame 23 realizes the vertical guiding function for barrels of different size specifications, prevents the problem of the barrel tipping over in the freezing cylinder 21, and helps to improve the stability of the pressing action of the check cylinder 22 on the barrel.

[0031] Combined with Figure 4 and Figure 8As shown in the figure, in this embodiment, at least two circumferentially arranged elastic buffer members 34 may also be provided on the upper side of the bottom plate 32 of the receiving cylinder 31, so as to buffer the falling barrel body through the elastic buffer members 34 and prevent the barrel body from being damaged due to hard impact with the bottom plate 32. The elastic buffer member 34 is preferably a rubber gasket, or it may also be a spring arranged vertically. When the barrel body falls into the receiving cylinder 31, it will contact the rubber gasket or the spring, achieving a good buffering effect on the barrel body.

[0032] Further, a cylindrical second limiting frame 33 with a vertical axis is provided in the receiving cylinder 31. The side wall of the second limiting frame 33 is grid-shaped. The inside of the second limiting frame 33 is available for the barrel body to enter. The inner diameter of the upper end of the second limiting frame 33 is larger than that of the lower end. Thus, the second limiting frame 33 realizes the vertical guiding function for barrel bodies of different sizes and specifications, prevents the problem of the barrel body tipping over in the receiving cylinder 31, and can ensure that the barrel body can accurately receive the buffering of the elastic buffer member 34.

[0033] Combined with Figure 4 As shown in the figure, as another improvement scheme for the above embodiment, a vibrator 63 is provided on the second jaw 61. The vibrator 63 is used to abut against the barrel body and drive the barrel body to vibrate. Thus, before the barrel body is impacted, the vibrator 63 can vibrate the barrel body in advance, so that the inner wall of the barrel body is partially separated from the impurities. Then, when the barrel body is impacted subsequently, the impurities can better fall off relative to the inner wall of the barrel body.

[0034] Combined with Figure 2 、 Figure 5 and Figure 9 As shown in the figure, regarding the cleaning assembly, in one embodiment, the cleaning assembly includes an aggregate basin 41, a rotating shaft 42 rotatably connected to the aggregate basin 41 with a vertical axis, a brush scraper connected to the upper end of the rotating shaft 42, and a rotating motor 43 acting on the rotating shaft 42 to drive the rotating shaft 42 to rotate. Thus, the brush scraper is driven by the rotating shaft 42 to brush the inner wall of the barrel body, further removing the residual impurities on the inner wall of the barrel body. The aggregate basin 41 can collect the fallen impurities to avoid pollution. The brush scraper can be in various forms, such as a brush 44, a scraper, a brush strip, etc., and is not limited thereto.

[0035] In another embodiment, the cleaning assembly includes an aggregate basin 41, a rotating shaft 42 rotatably connected to the aggregate basin 41 with a vertical axis, and a rotating motor 43 acting on the rotating shaft 42 to drive the rotation of the rotating shaft 42. An air passage is provided inside the rotating shaft 42, and an air blowing head (not shown in the figure) communicating with the air passage is provided at the upper end of the rotating shaft 42. The air outlet of the air blowing head is arranged obliquely downward. The air passage of the rotating shaft 42 supplies air to the air blowing head through an external blower, and the air blowing head can blow and sweep the inner wall of the barrel along with the rotation of the rotating shaft 42, so as to further remove the residual impurities on the inner wall of the barrel. The aggregate basin 41 can collect the fallen impurities to avoid pollution.

[0036] In another embodiment, the cleaning assembly includes an aggregate basin 41, a rotating shaft 42 rotatably connected to the aggregate basin 41 with a vertical axis, and a rotating motor 43 acting on the rotating shaft 42 to drive the rotation of the rotating shaft 42. An air passage is provided inside the rotating shaft 42, a suction head (not shown in the figure) communicating with the air passage is provided at the upper end of the rotating shaft 42, and a discharge port communicating with the air passage is provided at the lower end of the rotating shaft 42. Thus, the suction head rotates driven by the rotating shaft 42 to suck the impurities on the inner wall of the barrel, so as to further remove the residual impurities on the inner wall of the barrel. The impurities sucked by the suction head are discharged into the aggregate basin 41 through the air passage from the discharge port for collection to avoid pollution.
