Description

Technical Field

[0001] The utility model belongs to the technical field of container cleaning equipment, and particularly relates to storage barrel cleaning equipment. Background Art

[0002] Storage barrels refer to barrels that hold solutions, solid powders and other substances. Storage barrels for certain substances are recycled, and they need to be cleaned before recycling to prevent the residues of the previous batch of substances from affecting the quality of the next batch. Taking electrolyte barrels as an example, electrolyte is an essential raw material for batteries, and the electrolyte has extremely high requirements for the quality of electrolyte barrels, with impurities required at the parts per million level (ppm level). Therefore, in order to achieve the purpose of recycling electrolyte barrels while ensuring the quality of electrolyte, the electrolyte barrels must be cleaned to reduce the impurity content in the barrels and prevent the residues of the previous batch of electrolyte in the barrels from affecting the quality of the next batch of electrolyte. When cleaning electrolyte barrels, both the inner and outer walls of the electrolyte barrels need to be cleaned, and the cleaning requirements for the inner and outer walls are different. The usual cleaning method in the prior art is to clean the inner wall first: the worker first opens the lid on the barrel mouth of the electrolyte barrel, then injects the cleaning water into the electrolyte barrel, then uses a long-handled brush to scrub the inner wall of the electrolyte barrel, and then pours out the water in the electrolyte barrel. This is repeated many times before the inside of the electrolyte barrel can be cleaned. Since the structure of the electrolyte barrel itself has a slender entrance and the inside is pear-shaped, there are dead corners that cannot be cleaned during the cleaning process. Manual cleaning will leave dead corners, and the work intensity is high and the degree of automation is low. Although Chinese Patent Announcement No. CN215236572U discloses an electrolyte barrel cleaning device, the patent only solves the suction and drying of the electrolyte, and does not solve the cleaning problem of the electrolyte barrel.

[0003] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a storage barrel cleaning device to solve the shortcomings of the prior art. Utility Model Content

[0041] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0042] Example 1

[0043] A storage barrel cleaning device, such as Figures 1 to 3 As shown, a cleaning chamber 100, a barrel turning mechanism 300 for turning the storage barrel 400 from the outside of the cleaning chamber 100 to the inside of the cleaning chamber 100, and a cleaning arm 200 for spraying and flushing the outer wall and the inner wall of the storage barrel 400 360 degrees are provided. The barrel turning mechanism 300 is installed on the outside of the cleaning chamber 100, and the cleaning arm 200 is installed on the cleaning chamber 100.

[0044] It should be noted that when the storage barrel 400 is placed in the barrel turning mechanism 300, the opening of the storage barrel 400 faces upward, and when the storage barrel 400 is placed in the cleaning chamber 100, the opening of the storage barrel 400 faces downward. When describing the direction of the storage barrel 400, the utility model takes the opening direction as the top of the storage barrel 400, regardless of whether the storage barrel 400 is turned over.

[0045] The cleaning arm 200 is provided with an inner arm mechanism 210 for cleaning the inner and outer surfaces of the storage barrel 400 by lifting and rotating 360°, and an outer arm mechanism 220 for cleaning the outer surface of the storage barrel 400 by rotating 360°. The outer arm mechanism 220 can be rotatably assembled on the upper part of the cleaning bin 100, and the inner arm mechanism 210 is assembled on the lower part of the cleaning bin 100.

[0046] The inner arm mechanism 210 is provided with a first arm body 211, a first rotation driving assembly 212 for driving the first arm body 211 to rotate 360 ​​degrees, a first support frame 213, and a lifting driving assembly 214 for driving the first arm body 211 and the first rotation driving assembly 212 to lift and lower as a whole. The lifting driving assembly 214 is fixedly assembled at the bottom of the cleaning chamber 100, the first support frame 213 is fixedly assembled at the moving end of the lifting driving assembly 214, the first rotation driving assembly 212 is fixedly connected to the first support frame 213, one end of the first arm body 211 is transmission-connected to the first rotation driving assembly 212, and the other end of the first arm body 211 passes through the interior from the bottom of the cleaning chamber 100, as shown in FIG. Figure 4 .

[0047] It should be noted that the upper surface of the storage barrel 400 is cleaned before the first arm 211 enters the storage barrel 400, and then the first arm 211 is driven to enter the storage barrel 400 and rise toward the inner bottom surface of the storage barrel 400 by the lifting drive assembly 214 during the cleaning process, and the first rotating drive assembly 212 drives the first arm 211 to rotate during the insertion process, so as to achieve full coverage and flushing of the inner surface of the storage barrel 400. The lifting drive assembly 214 of this embodiment is a linear motor.

[0048] The first arm 211 is provided with a first liquid inlet 2111, a first connecting shaft tube 2112, a cleaning tube 2113 and a first sleeve 2114. The first liquid inlet 2111 is connected to the cleaning liquid delivery tube. The first connecting shaft tube 2112 can be rotatably assembled inside the first liquid inlet 2111, and the first connecting shaft tube 2112 is sealed and fixedly connected to the cleaning tube 2113. The first sleeve 2114 is fixedly connected to the first support frame 213, and the cleaning tube 2113 can be rotatably passed through the first sleeve 2114. The first connecting shaft tube 2112 of the first arm 211 is surrounded by a plurality of first liquid inlet holes 2115, and the first liquid inlet holes 2115 are connected to the first liquid inlet 2111 of the first arm 211, such as Figure 5 and Figure 6 .

[0049] It should be noted that the rotatable connection between the first liquid inlet member 2111 and the first connecting shaft tube 2112 does not affect the cleaning liquid delivery pipe. Since there are multiple first liquid inlet holes 2115 distributed around the first connecting shaft tube 2112, the cleaning liquid can still enter the interior of the first connecting shaft tube 2112 during the rotation of the first connecting shaft tube 2112 and finally enter the cleaning tube 2113.

[0050] The outer arm mechanism 220 is provided with a second arm body 221, a second rotation drive assembly 222 for driving the second arm body 221 to rotate 360°, and a second support frame 223. The second support frame 223 is fixedly assembled on the top of the cleaning chamber 100, and the second rotation drive assembly 222 is fixedly assembled on the second support frame 223. The second arm body 221 is transmission-connected with the second rotation drive assembly 222, and the second arm body 221 passes through the inside of the cleaning chamber 100 from the top of the cleaning chamber 100. The second arm body 221 is provided with a main pipe 2211, a first sub-pipe 2212 for cleaning the bottom surface of the storage barrel 400, and a second sub-pipe 2213 for cleaning the side wall of the storage barrel 400. The two ends of the first sub-pipe 2212 are sealed and connected with the main pipe 2211 and the second sub-pipe 2213 respectively, and the main pipe 2211 is transmission-connected with the second rotation drive assembly 222. The first sub-tube 2212 is perpendicular to the main tube 2211 and the second sub-tube 2213, and the first sub-tube 2212 and the second sub-tube 2213 rotate 360 ​​degrees around the main tube 2211. The second arm 221 is provided with a plurality of nozzles 2214, which are distributed in the first sub-tube 2212 and the second sub-tube 2213. Figure 7-Figure 8 .

[0051] It should be noted that the second arm 221 is divided into a main pipe 2211, a first sub-pipe 2212 and a second arm 221. The main pipe 2211 is used to connect to the second rotary drive assembly 222 and input cleaning liquid. The first sub-pipe 2212 is used to clean the bottom surface of the storage bucket 400, and the second sub-pipe 2213 is used to clean the side wall of the storage bucket 400. The second rotary drive assembly 222 drives the main pipe 2211 to rotate during the cleaning process, so that the first sub-pipe 2212 and the second arm 221 rotate 360° with the main pipe 2211 as the central axis to fully clean the bottom surface of the storage bucket 400. The second arm 221 rotates around the side wall of the storage bucket 400 to fully clean the side of the storage bucket 400. Figure 3 The nozzle 2214 lead-out connection is the range for the nozzle 2214 to spray the cleaning liquid.

[0052] The second arm 221 is also provided with a second liquid inlet 2215, a second connecting shaft tube 2216 and a second sleeve 2217. The second liquid inlet 2215 is connected to the cleaning liquid delivery pipe. The second connecting shaft tube 2216 can be rotatably assembled inside the second liquid inlet 2215, and the second connecting shaft tube 2216 is sealed and fixedly connected to the main pipe 2211. The second sleeve 2217 is fixedly connected to the second support frame 223, and the main pipe 2211 can be rotatably passed through the second sleeve 2217. The second connecting shaft tube 2216 of the second arm 221 is surrounded by a plurality of second liquid inlet holes 2218, and the second liquid inlet holes 2218 are connected to the second liquid inlet 2215 of the second arm 221. Figure 9-11 .

[0053] It should be noted that the rotatable connection between the second liquid inlet member 2215 and the second connecting shaft tube 2216 does not affect the cleaning liquid delivery pipe. Since a plurality of second liquid inlet holes 2218 are distributed around the second connecting shaft tube 2216, the cleaning liquid can still enter the interior of the second connecting shaft tube 2216 during the rotation of the second connecting shaft tube 2216, and finally enter the second cleaning tube 2113.

[0054] The cleaning bin 100 is provided with a bin body 110, a bin door 120 for closing the bin body 110 during cleaning, a support beam 130 for supporting a storage barrel 400, and a filter 140 for filtering solids. The bin door 120 can be movably assembled on the bin body 110, the support beam 130 is fixedly mounted inside the bin body 110, the filter 140 is detachably assembled at the water outlet of the bin body 110, and the first arm body 211 and the second arm body 221 both enter the interior of the bin body 110.

[0055] It should be noted that the function of the chamber door 120 is to prevent the cleaning liquid from spraying to the outside of the cleaning chamber 100 during the cleaning process, and the filter 140 is used to filter solid impurities in the cleaning waste liquid.

[0056] The barrel turning mechanism 300 is provided with a turning drive mechanism 310, a rotating rod 320, a frame 330 and at least one pair of clamping arms 340 for fixing the storage barrel 400. The turning drive mechanism 310 is transmission connected to the rotating rod 320, the frame 330 is fixedly connected to the rotating rod 320, and each pair of clamping arms 340 is respectively assembled on both sides of the frame 330.

[0057] The working process of the storage barrel cleaning device of the utility model is as follows: the operator puts the storage barrel 400 to be cleaned with the opening facing upward into the frame 330, and then fixes the storage barrel 400 with the clamping arm 340, and the flipping drive mechanism 310 drives the rotating rod 320, the frame 330 and the storage barrel 400 to flip 180 degrees so that the opening of the storage barrel 400 to be cleaned faces downward, and flips it into the cleaning chamber 100 and is erected on the support beam 130, and the inner arm mechanism 210 first cleans the upper surface of the storage barrel 400 before entering the storage barrel 400, and then the lifting drive assembly 214 drives the first arm body 211 to enter the interior from the opening of the storage barrel 400, and fully covers the inner surface of the storage barrel 400 for cleaning, and at the same time, the second rotating drive assembly 222 brings the second arm body 221 to fully cover and clean the lower bottom surface and side wall of the cleaning storage barrel 400, and after cleaning, the barrel flipping mechanism 300 resets the storage barrel 400.

[0058] The storage barrel cleaning device first turns the storage barrel 400 over by using the barrel turning mechanism 300 and sends it into the interior of the cleaning chamber 100, and then the cleaning arm 200 sprays and rinses the inside and outside of the storage barrel 400 360 degrees without dead angles, and after the cleaning is completed, the storage barrel 400 is turned over and taken out. The storage barrel cleaning device can automatically turn over the storage barrel 400 and clean the inside and outside of the storage barrel 400 360 degrees without dead angles, thereby improving the cleaning cleanliness and reducing labor input.

The electrolyte barrel cleaning device first turns over the electrolyte barrel by using a barrel turning mechanism 300 and sends it into the interior of a cleaning chamber 100, and then the cleaning arm 200 sprays and rinses the inside and outside of the electrolyte barrel 360 degrees without dead angles. After the cleaning is completed, the electrolyte barrel is turned over and taken out. The electrolyte barrel cleaning device can automatically turn over the electrolyte barrel and clean the inside and outside of the electrolyte barrel 360 degrees without dead angles, thereby improving the cleaning cleanliness and reducing labor input.
