Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, and more specifically, it relates to an anti-sedimentation stirring tank. Background Technology

[0002] When processing PVC lubricants, the finished PVC lubricant needs to be stored. To prevent the lubricant from settling, separating, or accumulating on the tank wall due to standing, and to ensure that the material remains uniform, a mixing tank is generally used to continuously and uniformly stir the PVC lubricant. Existing mixing tanks are mostly made of corrosion-resistant stainless steel or PVC sheets, and are equipped with a suitable stirring system. With a central stirring shaft as the core, and anchor or ribbon stirring blades, it can adhere to the tank wall and push the material to form a circulating flow. At the same time, a wall scraping device is often provided to clean the material adhering to the tank wall simultaneously with stirring. The drive device consists of a motor, reducer, etc., and the speed can be adjusted to adapt to the stirring needs of different stages, avoiding material splashing or excessive foaming. The overall design takes into account storage stability and stirring efficiency, which not only meets the long-term storage requirements of high anti-adhesion PVC lubricant, but also maintains its uniformity through dynamic stirring, providing a stable raw material guarantee for subsequent polymer material processing.

[0003] The existing application number is CN201821087635.X. This utility model discloses an electrically heated mixing tank for easily and evenly mixing an industrial rust-inhibiting lubricant. The tank includes a main body, which is equipped with a frame, a feeding port, a heater, a discharge port, a motor, and a support. The frame is fixedly connected to the top of the main body, the feeding port is fixedly connected to the right side of the top of the main body, the heater is fixedly connected to the inner side of the main body, the discharge port is fixedly connected to the bottom of the main body, and the motor is fixedly connected to the top of the main body, located inside the frame. The motor is equipped with a drive shaft, a connecting plate, and a spring, and the drive shaft is fixedly connected to the lower end of the motor. This electrically heated mixing tank for easily and evenly mixing an industrial rust-inhibiting lubricant utilizes a motor to drive a stirring blade and a U-shaped stirring blade to rotate. The U-shaped stirring blade and the stirring blade work together to thoroughly mix the mixture. A shock-absorbing spring reduces the damage to the machine body caused by vibration during motor operation.

[0004] Based on the above, after the PVC lubricant in the existing mixing tank is discharged, due to the high viscosity of the PVC lubricant, some of the PVC lubricant will adhere to the surface of the mixing paddle. Subsequently, workers need to wash the mixing paddle, which not only leads to the waste of PVC lubricant products, but also results in high labor intensity for workers. Utility Model Content

[0012] Furthermore, the stirring anti-sticking mechanism also includes: anti-sticking protrusions, anti-sticking fixing components, anti-sticking striking components, and anti-sticking striking springs; multiple sets of anti-sticking protrusions are provided, and the multiple sets of anti-sticking protrusions are respectively fixedly connected to the outer periphery of the stirring shaft; the anti-sticking fixing components are fixedly connected to the upper inner part of the mixing tank body; multiple sets of anti-sticking striking components are provided, and the multiple sets of anti-sticking striking components are respectively slidably connected to the lower inner side of the anti-sticking fixing components, and a sealing ring structure is provided at the connection between the multiple sets of anti-sticking striking components and the anti-sticking fixing components; multiple sets of anti-sticking striking springs are provided, and the multiple sets of anti-sticking striking springs are respectively fixedly connected to the outer side of the anti-sticking striking components, and the outer side of the multiple sets of anti-sticking striking springs is fixedly connected to the anti-sticking fixing components.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the setting of an anti-settling drive mechanism, opens the anti-settling conveying pump, which then adds the material from the bottom of the mixing tank back into the mixing tank body through the anti-settling conveying pipe, allowing the material to circulate and mix. This ensures that the material in the mixing tank body is more thoroughly stirred and mixed, especially in areas at the bottom of the mixing tank body where sediment is prone to settle. It can effectively bring the settled material back to the mixing area, preventing the accumulation of sediment.

[0015] This invention utilizes a stirring anti-sticking mechanism. When the stirring drive motor is turned on, its output shaft rotates, causing the stirring connector to rotate. This rotation, in turn, causes the stirring shaft to rotate, thus stirring the material. The rotating shaft then drives the wall scraper drive shaft, which in turn drives the wall scraper, which cleans the inner wall of the mixing tank. This prevents material from adhering to the inner wall of the mixing tank and avoids the accumulation and sedimentation of PVC lubricant, ensuring effective stirring and material uniformity. When the lifting drive motor is turned on, its output shaft rotates, causing the lifting drive screw to rotate. This rotation moves the stirring shaft up and down, increasing the stirring range.

[0016] This invention utilizes a stirring anti-sticking mechanism. A lifting drive motor rotates the lifting drive screw, moving the stirring shaft upwards. This causes the anti-sticking protrusions to contact the anti-sticking striking parts. Turning on the stirring drive motor causes the stirring shaft to rotate, dislodging any adhering PVC lubricant. Simultaneously, the rotating shaft causes the anti-sticking protrusions to rotate, alternately contacting the anti-sticking striking parts. Under the action of the anti-sticking striking spring, the striking parts strike the stirring shaft, causing it to vibrate while rotating. This accelerates the removal of the PVC lubricant, preventing it from sticking together and achieving self-cleaning of the stirring shaft. This reduces PVC lubricant waste and alleviates the labor intensity for workers. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example 1:

[0026] As attached Figures 1 to 2 As shown:

[0035] The anti-adhesion mechanism further includes: anti-adhesion protrusions 206, anti-adhesion fixing parts 207, anti-adhesion striking parts 208, and anti-adhesion striking springs 209; multiple sets of anti-adhesion protrusions 206 are provided, and multiple sets of anti-adhesion protrusions 206 are respectively fixedly connected to the outer periphery of the stirring shaft 4; the anti-adhesion fixing parts 207 are fixedly connected to the upper inner end of the mixing tank body 1; multiple sets of anti-adhesion striking parts 208 are provided, and multiple sets of anti-adhesion striking parts 208 are respectively slidably connected to the lower inner end of the anti-adhesion fixing parts 207, and a sealing ring structure is provided at the connection between the multiple sets of anti-adhesion striking parts 208 and the anti-adhesion fixing parts 207; multiple sets of anti-adhesion striking springs 209 are provided, and multiple sets of anti-adhesion striking springs 209 are respectively fixedly connected to the outer side of the anti-adhesion striking parts 208, and the outer side of the multiple sets of anti-adhesion striking springs 209 is fixedly connected to the anti-adhesion fixing parts 207.

[0036] The specific usage and function of this embodiment are as follows: When stirring the stored PVC lubricant, the stirring drive motor 2 is turned on. The output shaft of the stirring drive motor 2 rotates, causing the stirring connector 201 to rotate. The rotation of the stirring connector 201 causes the stirring shaft 4 to rotate, thus stirring the material. The rotation of the stirring shaft 4 also causes the wall scraping drive shaft 204 to rotate, which in turn causes the wall scraping component 205 to rotate. The rotation of the wall scraping component 205 cleans the inner wall of the mixing tank body 1, preventing material from adhering to the inner wall of the mixing tank body 1 and preventing the PVC lubricant from accumulating and settling on the inner wall of the mixing tank body 1, ensuring the stirring effect and the uniformity of the material.

The rotation of the lifting drive screw 203 causes the stirring shaft 4 to move up and down, stirring the material. The vertical movement of shaft 4 increases the mixing range. Simultaneously, when the PVC lubricant is discharged, the lifting drive motor 202 drives the lifting drive screw 203 to rotate, moving the mixing shaft 4 upwards. This causes the anti-adhesion protrusion 206 to contact the anti-adhesion striking element 208. The stirring drive motor 2 is then turned on, causing the mixing shaft 4 to rotate. This rotation of the mixing shaft 4 dislodges the adhering PVC lubricant. Simultaneously, the rotation of the mixing shaft 4 causes the anti-adhesion protrusion 206 to rotate, alternately contacting the anti-adhesion striking element 208. Under the action of the anti-adhesion striking spring 209, the anti-adhesion striking element 208 strikes the mixing shaft 4, causing it to vibrate while rotating. This accelerates the removal of the PVC lubricant, preventing it from sticking together and achieving self-cleaning of the mixing shaft 4. This reduces the waste of PVC lubricant and alleviates the labor intensity of workers.
