Description

Technical Field

[0001] This utility model belongs to the field of chemical safety technology, specifically relating to a safety cleaning device for chemical drums. Background Technology

[0002] As storage containers for chemicals, the cleanliness of chemical drums directly affects the quality of the chemicals. If the drums contain residual chemicals from the previous shipment, these residual chemicals may react with the newly loaded chemicals, causing the chemicals to deteriorate or produce harmful substances.

[0003] To avoid this situation, brushes are typically used to clean the inner walls of chemical drums to remove residual chemicals and maintain the quality of the chemicals. However, due to the different sizes of chemical drums, commonly used brushes, although some with flexible bristles that can bend to fit the inner wall of the drum, are prone to deformation under pressure, resulting in lower cleaning power and poor cleaning effectiveness. If uncleaned chemical drums are used in production, the residual contaminants may react chemically with the raw materials, causing product spoilage. This would not only damage the company's reputation but could also cause significant economic losses.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a safe cleaning device for chemical drums. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figure 1 As shown in the figure, a chemical drum safety cleaning device according to one embodiment of the present invention includes a chemical drum body 1, with a cleaning mechanism provided at one end of the chemical drum body 1. When it is necessary to clean the chemical drum body 1, the cleaning mechanism is brought into contact with the inner wall of the chemical drum body 1, and the chemical drum body 1 or the cleaning mechanism is rotated to remove the chemical substances adhering to the inner wall of the chemical drum body 1 through relative movement. Then, it is rinsed with clean water, thereby avoiding to a certain extent the reaction between the residual chemical substances and the newly loaded chemical substances, which could lead to the deterioration of the chemical products or the generation of harmful substances.

[0029] like Figures 2-4 As shown, the cleaning mechanism includes a threaded rod 201, with a rectangular rod 2011 mounted at one end. A first brush strip 204 is mounted at the end of the rectangular rod 2011 near the bottom of the chemical drum body 1. Multiple sets of adjusting frames 202 are mounted on the threaded rod 201, with brush bristles 203 mounted at the bottom of each adjusting frame 202. A locking assembly is mounted on the threaded rod 201 to restrict the movement of the adjusting frames 202. The locking assembly restricts the rotation or movement of the adjusting frames 202 on the threaded rod 201. The locking assembly includes a first locking assembly, which restricts the adjustment frames 202 from rotating with the threaded rod 201 during the cleaning process. The first locking assembly includes a locking nut 205, which is mounted on the threaded rod 201. The locking nut 205 abuts against a set of adjusting frames 202 away from the first brush strip 204, and friction exists between the locking nut 205 and the adjusting frames 202, and between the adjusting frames 202 themselves.

[0030] Specifically, one end of the threaded rod 201 connected to the first brush strip 204 is placed into the chemical drum body 1. The first brush strip 204 is in contact with the bottom of the chemical drum body 1. The adjusting frame 202 is moved towards the side wall of the chemical drum body 1, so that the bristles 203 are in contact with the inner side wall of the chemical drum body 1. Then, the locking nut 205 is rotated, and the locking nut 205 moves towards the adjusting frame 202 on the threaded rod 201, so that the multiple adjusting frames 202 are tightly connected. The friction between the adjusting frames 202 allows the brush composed of multiple adjusting frames 202 to better fit the inner wall of the chemical drum body 1, which is beneficial to improving the cleaning effect. At the same time, the rectangular rod 2011 prevents the adjusting frame 202 from rotating during the cleaning process, which would affect the cleaning effect.

[0031] Furthermore, the adjustment frame 202 can fit the chemical drum body 1 with different inner wall curvatures, that is, it can be applied to chemical drum bodies 1 of different specifications, which to a certain extent broadens the application range of the safety cleaning device for chemical drum bodies 1.

[0032] like Figure 3 As shown, the locking assembly also includes a limiting component, which is used to allow adjacent adjusting frames 202 to move in the same direction. The second locking assembly includes a second limiting strip 207, which is installed on the side of the adjusting frame 202 that contacts another set of adjusting frames 202. The other side of the adjusting frame 202 has a second sliding groove 2022 that matches the second limiting strip 207. When multiple adjusting frames 202 are engaged with each other through the second limiting strip 207, it is less likely that the adjusting frames 202 will swing left and right when the operator rotates the chemical drum body 1 or the cleaning mechanism.

[0033] like Figures 1-2As shown, a base 3 is installed below the chemical drum body 1. A support frame 301 matching the chemical drum body 1 is installed on the base 3. A drive component for rotating the chemical drum body 1 is installed on the support frame 301. A connecting component for fixing the cleaning mechanism is installed on the base 3. After the chemical drum body 1 is placed on the base 3, the chemical drum body 1 is rotated by the drive component, and the fixed cleaning mechanism cleans the inner wall of the chemical drum body 1 with the cooperation of the connecting component.

[0034] like Figures 1-2 As shown, the connecting assembly includes a support rod 302, which is mounted on the base 3. A connecting seat 303 is mounted on the top of the support rod 302 and is fixedly connected to the threaded rod 201. When the threaded rod 201 is mounted on the connecting seat 303, the connecting seat 303 restricts the movement of the connecting seat 303 through the base 3, thereby achieving the purpose of fixing the threaded rod 201.

[0035] like Figures 1-2 As shown, the support rod 302 has an external thread, and the base 3 has an internal thread that matches the external thread. The support rod 302 is threadedly connected to the base 3. Before the operator rotates the chemical drum body 1 using the drive assembly, the operator rotates the support rod 302. The external thread on the outer wall of the support rod 302 engages with the internal thread on the base 3, causing the cleaning mechanism to move downward. This generates a squeezing force between the cleaning mechanism and the inner wall of the chemical drum body 1, providing the necessary force to clean the inner wall of the chemical drum body 1, further improving the cleaning effect of the inner wall of the chemical drum body 1.

[0036] like Figure 2 As shown, the drive assembly includes a turntable 304, which is mounted on a support frame 301. A handle 305 is installed on one side of the support frame 301. When the chemical drum body 1 is manually rotated, the worker directly contacts the outer wall of the chemical drum body 1, potentially becoming contaminated with toxic or harmful chemicals. Therefore, rotating the handle 305 causes the turntable 304 to rotate. The friction between the turntable 304 and the outer wall of the chemical drum body 1 drives the chemical drum body 1 to rotate, thus improving the safety factor of the chemical drum body 1 cleaning device to a certain extent.

[0037] like Figure 2 As shown, a belt 306 matching the outer wall of the chemical drum body 1 is installed on the outer wall of the turntable 304. The belt 306 can effectively transmit the power provided by the turntable 304, minimize the slippage of the chemical drum body 1, and improve the rotation efficiency.

[0038] like Figure 3As shown, each side of the adjustment frame 202 is equipped with a first limiting strip 206, and the outer wall of the adjustment frame 202 is provided with a first sliding groove 2021 that matches the first limiting strip 206. When the chemical drums 1 to be cleaned are mostly of the same size and the adjustment frame 202 does not need to be adjusted frequently, the staff can open the first sliding groove 2021 on the adjustment frame 202 and insert the first limiting strip 206 of sufficient length into the first sliding groove 2021 to limit the movement of multiple sets of adjustment frames 202, reducing the number of adjustments and improving cleaning efficiency to a certain extent.

[0039] like Figure 5 As shown, the cleaning mechanism also includes a second brush strip 208, which is slidably connected to one end of the first brush strip 204. The first brush strip 204 has a connecting groove that matches the second brush strip 208. The first brush strip 204 and the second brush strip 208 work together to extend and retract, allowing them to fit chemical drum bodies 1 with different bottom diameters. This means the device can be applied to chemical drum bodies 1 of different specifications, thus expanding the application range of the safe cleaning device for chemical drum bodies 1 to a certain extent.

[0040] like Figure 5 As shown, an anti-slip plate 209 matching the second brush strip 208 is installed in the connecting groove. The anti-slip plate 209 and the second brush strip 208 are interference-fitted. The anti-slip plate 209 helps to increase the friction between the first brush strip 204 and the second brush strip 208, and to a certain extent prevents the second brush strip 208 from shortening during the rotation of the first brush strip 204 with the threaded rod 201, thus affecting the cleaning effect on the bottom of the chemical drum body 1.

[0041] During use, when it is necessary to clean the body 1 of chemical drums of different sizes, unscrew the locking nut 205, place the body 1 of chemical drums on the support frame 301, and under the action of gravity, the multiple adjustment frames 202 located inside the body 1 of chemical drums will automatically fit against the inner wall of the body 1 of chemical drums. Then, turn the locking nut 205 to lock the adjustment frames 202, and then turn the support rod 302. The support rod 302 will cause the multiple adjustment frames 202 to move down as a whole, providing the pressure required for cleaning. Then, turn the handle 305 to make the body 1 of chemical drums rotate. The relative movement between the body 1 of chemical drums and the bristles 203 will clean the inner wall of the body 1 of chemical drums. At the same time, it can be rinsed with clean water.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
