[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 - Figure 5 , the present utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A chemical steel drum resistant to strong alkali, comprising a steel drum 1, a liquid inlet pipe 2 and a liquid outlet pipe 3. The liquid inlet pipe 2 is fixedly communicated with the top of the steel drum 1, and the liquid outlet pipe 3 is fixedly communicated with one side of the steel drum 1. A connecting ring 4 is arranged inside the steel drum 1. Two rotating plates 5 are symmetrically and fixedly connected to the circumferential side of the connecting ring 4. A transmission groove 6 is formed at the bottom of the rotating plate 5. A transmission block 7 is arranged inside the transmission groove 6. A transmission rod 8 is fixedly connected to the bottom of the transmission block 7. A brush 9 is fixedly connected to the bottom of the transmission rod 8. A driving mechanism is arranged at the top of the steel drum 1;

[0029] The driving mechanism includes a support frame 10 fixedly connected to the top of the steel drum 1. A motor 11 is fixedly installed at the top of the support frame 10. The output end of the motor 11 penetrates through the support frame 10 and is fixedly connected to a rotating rod 13. The bottom of the rotating rod 13 penetrates into the inside of the steel drum 1 and is rotatably connected to the inner wall of the steel drum 1 through a rotating shaft. The surface of the rotating rod 13 is fixedly connected to the surface of the connecting ring 4. A reciprocating mechanism is arranged on one side of the transmission block 7.

[0030] In this embodiment, considering that the chemical steel drum 1 is stored and static for a long time, the chemicals will precipitate, resulting in adhesion to the bottom of the steel drum 1, which is inconvenient to take out and use later. Therefore, by setting the driving mechanism, the motor 11 can be started to drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, it will drive the rotating block and the rotating plate 5 to rotate. The rotating plate 5 will drive the transmission block 7, the transmission rod 8 and the brush 9 to rotate, so as to clean the bottom of the steel drum 1, thereby avoiding the situation that the chemicals adhere to the bottom of the steel drum 1;

[0031] It solves the problem that considering that the chemical steel drum 1 is stored and static for a long time, the chemicals will precipitate, resulting in adhesion to the bottom of the steel drum 1, which is inconvenient to take out and use later;

[0032] It should be noted that in this embodiment, the steel drum 1 is made of stainless steel and has strong alkali resistance.

[0033] A communication hole 20 matching with the rotating rod 13 is formed at the top of the steel drum 1. A sealing ring 21 is fixedly connected to the inner wall of the communication hole 20.

[0034] In this embodiment, by setting the communication hole 20 and the sealing ring 21, a space for the rotating rod 13 to enter the steel drum 1 can be provided. At the same time, by setting the sealing ring 21, chemical leakage can be avoided.

[0035] Three swing blades 22 are fixedly connected to the circumferential side of the rotating rod 13. A plurality of filter holes 12 are formed on the surface of the swing blades 22.

[0036] In this embodiment, by providing the swing blade 22 and the filter holes 12, while the rotating rod 13 rotates, the swing blade 22 can be driven to rotate, generating centrifugal force, further improving the anti-sedimentation effect of the steel barrel 1. At the same time, the filter holes 12 can reduce the resistance received by the swing blade 22.

[0037] Embodiment Two:

[0038] Based on Embodiment One, in this embodiment, the driving mechanism can control the rotation of the brush 9, so as to prevent chemicals from adhering to the bottom of the steel barrel 1. However, considering that it is difficult to completely remove the chemicals adhering to the bottom of the steel barrel 1 only by controlling the rotation of the brush 9 through the driving mechanism, in this application, the reciprocating mechanism includes a spring 14 fixedly connected to one side of the transmission block 7. One end of the spring 14 is fixedly connected to the inner wall of the transmission groove 6. A pressing rod 15 is fixedly connected to the side of the transmission block 7 away from the spring 14. One end of the pressing rod 15 penetrates to the outside of the transmission block 7 and is fixedly connected with a first pressing block 16. A second pressing block 17 that cooperates with the first pressing block 16 is fixedly connected to the inner wall of the steel barrel 1.

[0039] In this embodiment, considering that it is difficult to completely remove the chemicals adhering to the bottom of the steel barrel 1 only by controlling the rotation of the brush 9 through the driving mechanism, therefore, by providing the reciprocating mechanism, when the rotating plate 5 rotates, it will drive the first pressing block 16 to contact the second pressing block 17. When the spherical part of the first pressing block 16 contacts the inclined side part of the second pressing block 17, the first pressing block 16 will drive the pressing rod 15 and the transmission block 7 to move along the trajectories of the sliding block 18 and the sliding groove 19, and at the same time compress the spring 14. When the first pressing block 16 does not contact the second pressing block 17, affected by the reaction force of the spring 14, the transmission block 7 returns to its original position, achieving the reciprocating movement. The reciprocating movement of the transmission block 7 will drive the transmission rod 8 and the brush 9 to perform reciprocating movement, thereby increasing the cleaning force of the brush 9 and also improving the cleaning effect, further enhancing the anti-sedimentation effect of the steel barrel 1;

[0040] It solves the problem that it is difficult to completely remove the chemicals adhering to the bottom of the steel barrel 1 only by controlling the rotation of the brush 9 through the driving mechanism.

[0041] The first pressing block 16 is spherical, and both sides of the second pressing block 17 are sloped.

[0042] In this embodiment, by setting the first pressing block 16 as spherical and both sides of the second pressing block 17 as sloped, when the spherical part of the first pressing block 16 contacts the inclined side part of the second pressing block 17, the first pressing block 16 will drive the pressing rod 15 and the transmission block 7 to move along the trajectories of the sliding block 18 and the sliding groove 19, playing a role in transmission.

[0043] The number of the second extrusion blocks 17 is several, and they are evenly distributed in a ring on the inner wall of the steel barrel 1.

[0044] In this embodiment, by arranging several second extrusion blocks 17, when the first extrusion block 16 contacts the second extrusion block 17, the brush 9 will move reciprocally, thereby improving the cleaning effect of the brush 9.

[0045] A sliding block 18 is fixedly connected to the top of the transmission block 7, and a sliding groove 19 for cooperating with the sliding block 18 is formed in the inner wall of the transmission groove 6.

[0046] In this embodiment, by arranging the sliding block 18 and the sliding groove 19, when the first extrusion block 16 contacts the second extrusion block 17 to drive the transmission block 7, the transmission block 7 can be restricted to move only along the trajectories of the sliding block 18 and the sliding groove 19, and at the same time, the stability during the movement is improved.

[0047] Working principle: By starting the motor 11, the rotating rod 13 is driven to rotate. When the rotating rod 13 rotates, the rotating block and the rotating plate 5 will be driven to rotate. The rotating plate 5 will drive the transmission block 7, the transmission rod 8 and the brush 9 to rotate, so as to clean the bottom of the steel barrel 1, thereby avoiding the situation that chemicals adhere to the bottom of the steel barrel 1;

[0048] When the rotating plate 5 rotates, it will drive the first extrusion block 16 to contact the second extrusion block 17. When the spherical part of the first extrusion block 16 contacts the hypotenuse part of the second extrusion block 17, the first extrusion block 16 will drive the extrusion rod 15 and the transmission block 7 to move along the trajectories of the sliding block 18 and the sliding groove 19, and at the same time compress the spring 14. When the first extrusion block 16 does not contact the second extrusion block 17, affected by the reaction force of the spring 14, the transmission block 7 resets, achieving the effect of reciprocating movement. The reciprocating movement of the transmission block 7 will drive the transmission rod 8 and the brush 9 to move reciprocally, thereby improving the cleaning strength of the brush 9 and also improving the cleaning effect, and further improving the anti-precipitation effect of the steel barrel 1.

[0049] It should be noted that the motor 11 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art, and the specific composition and principle of the power supply of the motor 11 are clear to those skilled in the art, so it will not be elaborated in detail.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
