[0002] As a material mixing equipment widely used in modern industrial production, the traditional structural design of the stirred tank has noise control problems that need to be improved. Traditional stirred tank equipment is usually composed of a reactor body, a stirring device and a supporting drive system. During the operation of this type of stirred tank, the mechanical friction between the stirring device and the material and the operation of the power system will generate significant noise. Since traditional kettle bodies mostly adopt a single-layer metal wall structure and lack a sandwich sound-absorbing design, the overall sound insulation performance of the equipment is insufficient. This acoustic defect is particularly prominent in places that are sensitive to the sound environment, such as laboratories. Continuous noise pollution will cause auditory fatigue to operators, and long-term exposure may even cause occupational hearing damage. Utility Model Content

[0040] A driving member 1 is provided on the transmission assembly 2, and a first output end and a second output end of the transmission assembly 2 are respectively connected to a transfer shaft cylinder 3 and a mixing paddle 4, the mixing paddle 4 is inserted into the transfer shaft cylinder 3, and one end of the transfer shaft cylinder 3 is connected to a stirring assembly 5; the driving member 1 can drive the mixing paddle 4 and the stirring assembly 5 to move synchronously through the transmission assembly 2.

[0041] The adapter shaft cylinder 3 is rotatably connected to the kettle cover 7 .

[0042] A focusing cylinder 6 is arranged inside the kettle body 8 , and a mixing paddle 4 is cooperatively arranged inside the focusing cylinder 6 .

[0043] The mixing paddle 4 is in the shape of an auger and includes a spiral shaft on which spiral blades are arranged. Figure 1As shown; in this embodiment, the spiral blade part of the mixing paddle 4 rotates in the focusing tube 6, thereby spirally pushing the material in the kettle body 8 into the focusing tube 6. Under the continuous push of the mixing paddle 4, the material flows out of the focusing tube 6 to form a liquid flow, and the liquid flow impacts and mixes the whole material.

[0044] The muffler housing comprises an upper shell 10 which is covered on the kettle cover 7 and a lower shell 9 which is sleeved on the outside of the kettle body 8 . A plurality of muffler plates 11 are evenly arranged between the outer wall of the kettle body 8 and the inner wall of the lower shell 9 .

[0045] Specifically, the transmission assembly 2 includes a support housing 201 , in which a driving wheel 202 , a transfer wheel 203 and a driven wheel 204 that are meshed in sequence are disposed.

[0046] The driving wheel 202 is coaxially connected with the output shaft of the driving member 1 and the mixing paddle 4;

[0047] The upper portion of the mixing paddle 4 is inserted into the driven wheel 204;

[0048] The driven wheel 204 is coaxially connected to the adapter shaft cylinder 3 .

[0049] In this embodiment, the driving member 1 is a motor; the driving wheel 202, the transfer wheel 203 and the driven wheel 204 are bevel gears, and the three are rotatably connected to the inside of the support shell 201 respectively; the power of the driving member 1 can be transmitted to the driving wheel 202 and the mixing paddle 4, and the driving member 1 drives the driving wheel 202 and the mixing paddle 4 to rotate synchronously. At the same time, the power of the driving member 1 can also be transmitted to the driven wheel 204 through the driving wheel 202 and the transfer wheel 203, and the driven wheel 204 further drives the transfer shaft 3 and the stirring assembly 5 to rotate.

[0050] Specifically, the stirring assembly 5 includes: an adapter frame 501 connected to the adapter shaft cylinder 3 , and a stirring cage 502 is connected to the adapter frame 501 .

[0051] Specifically, the focusing cylinder 6 includes a cylinder body 601, and a plurality of support rods 602 are provided on the outer wall of the cylinder body 601. The cylinder body 601 is connected to the kettle body 8 through the support rods 602; the spiral blade half of the mixing paddle 4 is inserted into the cylinder body 601; the support rods 602 provide stable support for the cylinder body 601.

[0052] The stirring cage 502 is disposed on the periphery of the cylinder 601 .

[0053] Specifically, a guide platform 801 is provided at the bottom of the kettle body 8, and the guide platform 801 is arranged below the outlet of the cylinder 601; the guide platform 801 is streamlined. In this embodiment, the guide platform 801 guides the liquid flow discharged from the cylinder 601 to the inner wall of the kettle body 8. After passing through the obstruction of the inner wall, the liquid flow impacts the material flow outside the cylinder 601. At the same time, the stirring cage 502 stirs the material outside the cylinder 601, thereby enhancing the mixing effect of the material.

[0054] Specifically, a first slot 802 is provided on the outer wall of the kettle body 8; a second slot 902 is provided on the inner wall of the lower shell 9; and a plurality of silencer rings 901 are provided at the bottom of the lower shell 9;

[0055] The first card slot 802 and the second card slot 902 are arranged alternately, and the first card slot 802 and the second card slot 902 are respectively inserted with a sound-absorbing plate 11 .

[0056] In this embodiment, the sound insulation layer 1003, the sound absorbing ring 901 and the sound absorbing plate 11 are all made of sound insulation foam. The sound absorbing ring 901 is arranged in a concentric nested manner with a gap, such as Figure 1 As shown; the silencer plate 11 and the silencer ring 901 divide the continuous annular chamber between the kettle body 8 and the lower shell 9 into several small chambers. When the sound waves pass through these small chambers, the propagation distance is extended through multiple reflection paths. The sound energy is gradually weakened after being absorbed by the porous structure of the sound insulation foam, thereby achieving a sound insulation effect.

[0057] Specifically, the upper shell 10 includes: an outer shell 1002, the inner wall of which is covered with a sound insulation layer 1003; and a hatch 1001 is also provided on the outer shell 1002. The hatch 1001 can form an operation window when opened, which is convenient for operators to add or extract materials to the mixing tank body, and also convenient for operators to observe the operating status of the mixing tank body.

[0058] The specific use principle of the utility model is as follows:

[0059] After the driving part 1 is started, dual power output is achieved through the transmission assembly 2: on the one hand, the mixing paddle 4 is directly driven to rotate, and on the other hand, the mixing assembly 5 of the adapter shaft cylinder 3 is driven to rotate through the driving wheel 202, the adapter wheel 203 and the driven wheel 204. The auger structure of the mixing paddle 4 forms a forced spiral conveying in the cylinder 601, and continuously pushes the upper layer of materials to the bottom of the cylinder 601 to form a high-pressure liquid flow. The liquid flow is guided by the streamlined guide platform 801 to form an annular impact flow along the inner wall of the kettle body 8, which continuously impacts and mixes the materials; the mixing method of liquid flow impact avoids the impact noise of the machinery and materials caused by the stirring of the mechanical device.

[0060] The synchronously operated stirring assembly 5 drives the stirring cage 502 through the adapter frame 501 to stir the material after the liquid flow impacts the outer periphery of the focusing tube 6 to form a stirring flow field. The high-speed liquid flow inside the focusing tube 6 and the outer stirring flow field generate turbulent interference to achieve double mixing.

[0061] During the stirring process, the silencer ring 901 and the silencer plate 11 block the sound wave conduction path and absorb the noise generated by the stirring body; the sound insulation layer 1003 absorbs the noise from the driving member 1 and the kettle cover 7.

[0062] Of course, the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and any equivalent changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention shall fall within the scope of the patent coverage of the present invention.
