[0002] The existing anti-deposition storage tank generally prevents the accumulation of sediment in the liquid by setting a simple stirring assembly in the tank body. This type of stirring assembly generally adopts a single impeller or paddle structure, which attempts to suspend the sediment in the liquid by rotating the blades to drive the liquid flow. However, due to the simple structure of these stirring assemblies, the stirring range is limited, especially at the bottom and edge areas of the storage tank, the stirring effect is poor, which leads to easy accumulation of sediment. This situation not only affects the quality of the liquid, but also increases the difficulty of maintaining the storage tank, frequent cleaning of sediment can cause the storage tank to stop, reducing production efficiency.

Therefore, the existing technology has significant deficiencies in preventing sediment accumulation, and a more effective stirring and anti-deposition technology is urgently needed to improve the quality control capability of liquid storage.

[0029] It is to be understood that the descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0030] The specific embodiments of the utility model will be further described below in conjunction with the accompanying drawings. Figures 1-5 Some embodiments of the utility model provide a kind of anti-precipitation storage tank.

[0031] In conjunction with the drawings shown, the utility model provides a kind of anti-precipitation storage tank, including storage tank main body 100, drive bottom box 200 and precipitate dispersion component 300.

[0032] Drive bottom box 200 is fixed to the bottom of storage tank main body 100, and is internally provided with anticorrosive shaft box 210, and anticorrosive shaft box 210 is sealingly connected with the bottom surface of storage tank main body 100, and rotor disc 220 is rotatably installed in the inside of anticorrosive shaft box 210.Rotor disc 220 surface is equipped with several uniform distribution permanent magnetic patches 221, and drive bottom box 200 is equipped with several excitation coils 230 corresponding to permanent magnetic patches 221, and excitation coil 230 generates high-frequency alternating current by current generator, so that magnetic repulsion and attraction are generated between excitation coil 230 and permanent magnetic patch 221, and then drive rotor disc 220 to rotate.

[0033] Precipitate dispersion component 300 is driven to run by rotor disc 220, and precipitate dispersion component 300 includes mixing and stirring cylinder 310, shaft 320, import impeller 330, centrifugal impeller 340, lifting rotary vane 350 and dispersion disc 360.Shank 320 is installed in the inside of mixing and stirring cylinder 310, and import impeller 330, centrifugal impeller 340, lifting rotary vane 350 and dispersion disc 360 are fixed on the surface of shaft 320 from below to above in turn.

[0034] In specific implementation process, import impeller 330 guides the precipitate and liquid into the inside of mixing and stirring cylinder 310 when rotating, and centrifugal impeller 340 utilizes the centrifugal force of rotation to carry out primary separation and dispersion to the precipitate.Mixing and stirring cylinder 310 surface is equipped with a plurality of separation outlets 311, and these separation outlets 311 are located at the outer periphery of centrifugal impeller 340, for discharging the precipitate and liquid of primary dispersion.At the same time, part of the precipitate and liquid is lifted to the top end of mixing and stirring cylinder 310 by the action of lifting rotary vane 350, and is discharged through upwelling outlet 312, and the rotation of dispersion disc 360 again realizes the crushing and dispersion of the precipitate.

[0035] The bottom surface of the anticorrosion shaft box 210 is fixedly connected with the bottom of the storage tank body 100, and the connection between the shaft rod 320 and the rotor disc 220 is sealed through a mechanical seal, so that the transmission components in the anticorrosion shaft box 210 are prevented from being corroded by liquid, and the anticorrosion performance is effectively improved.

[0036] The utility model discloses a magnetic driving system and a multi-stage dispersion device are used to realize the effective dispersion and prevention of the deposition in the storage tank.

[0037] The utility model discloses a magnetic driving system and a multi-stage dispersion device are used to realize the effective dispersion and prevention of the deposition in the storage tank.

[0038] The working principle and use flow of the utility model are as follows:

[0039] The core working principle of the utility model discloses a deposition storage tank is that the effective dispersion and prevention of the deposition in the storage tank are realized through a magnetic driving system and a multi-stage dispersion device.

[0040] Magnetic power driving system:

[0041] The drive bottom box 200 is equipped with the excitation coil 230, and the excitation coil 230 is provided with high-frequency alternating current by a current generator, and the excitation coil 230 and the permanent magnet patch 221 on the rotor disc 220 generate magnetic repulsion and attraction, and drive the rotor disc 220 to rotate.

[0042] Multi-stage dispersion device:

[0043] The deposition dispersion assembly 300 is rotated by the rotor disc 220, and the guide-in impeller 330, the centrifugal impeller 340, the lifting rotary blade 350 and the dispersion disc 360 in the assembly complete the multi-stage dispersion treatment of the deposition in turn.

[0044] The guide-in impeller 330 first introduces the deposition and liquid into the inside of the mixing cylinder 310.

[0045] The centrifugal impeller 340 disperses the deposition through centrifugal force for the first time, and makes part of the deposition discharge through the separation outlet 311 on the surface of the mixing cylinder 310.

[0046] The lifting vanes 350 axially lift the remaining sediment and carry it to the top of the mixing cylinder 310, where it is discharged through the upwelling outlet 312.

[0047] Finally, the rotational motion of the dispersion disc 360 further breaks and disperses the lifted sediment, ensuring that it does not form clumps within the tank and that the liquid remains uniformly flowing throughout the tank.

[0048] Corrosion-resistant sealing system:

[0049] The design of the corrosion-resistant shaft box 210 ensures that the drive mechanism within the tank is isolated from the liquid, preventing corrosion of the drive mechanism. The mechanical seal between the shaft 320 and the rotor disc 220 further enhances the sealing performance.

[0050] Usage process:

[0051] Starting the drive system:

[0052] The user starts the drive by activating the excitation coil 230 in the drive box 200 using a current generator, which provides high-frequency alternating current to the excitation coil 230. Under the action of magnetic force, the rotor disc 220 begins to rotate, driving the sediment dispersion assembly 300 to start working.

[0053] Sediment introduction and initial dispersion:

[0054] As the rotor disc 220 rotates, the introduction impeller 330 introduces the sediment and liquid at the bottom of the tank into the mixing cylinder 310. The centrifugal impeller 340 then performs initial dispersion of the sediment through centrifugal force generated by rotation, separating smaller particles of sediment and discharging them through the separation outlet 311.

[0055] Lifting and further dispersion of sediment:

[0056] After initial dispersion, the remaining sediment is axially lifted by the lifting vanes 350, pushing it to the top of the mixing cylinder 310 and discharging it through the upwelling outlet 312. At this time, the dispersion disc 360 rotates to further break and disperse the lifted sediment, ensuring that it is completely dispersed in the liquid and preventing the formation of sediment clumps.

[0057] Global disturbance and uniform liquid maintenance:

[0058] During the entire rotation process, the sediment dispersion assembly 300 creates strong horizontal and vertical mixing flow disturbances within the tank, ensuring that the liquid and sediment in the entire tank area are uniformly dispersed, preventing sediment accumulation at the bottom of the tank.

[0059] Regular maintenance and inspection:

[0060] The user can regularly check the sealing of the drive bottom box 200 and the corrosion-proof shaft box 210 according to the use condition, ensure the normal work of the excitation coil 230 and the permanent magnetic block 221, and maintain the high efficiency operation of the equipment and prolong the service life.

[0061] By adopting the utility model, the user can effectively prevent the accumulation of the sediment in the storage tank, realize the uniform storage and high-quality preservation of the liquid, and is especially suitable for the liquid storage scene containing solid particles.
