Technical Field

[0001] The utility model relates to the technical field of magnesium stearate processing, in particular to a magnesium stearate air separation device. Background Art

[0002] Magnesium stearate, with the chemical formula C36H70MgO4 and a molecular weight of 591.24, is an organic compound of magnesium stearate. It is a white, sand-free fine powder that feels greasy when in contact with the skin. It is insoluble in water, ethanol or ether and is mainly used as a lubricant, anti-adhesive agent and flow aid. It is particularly suitable for the granulation of oils and extract drugs, and the granules produced have good fluidity and compressibility. It is used as a flow aid in direct tableting. It can also be used as a filter aid, clarifier and dripping agent, as well as a suspending agent and thickener for liquid preparations.

[0003] In the process of preparing the existing magnesium stearate powder, the wet magnesium stearate powder is first dried by a dryer, and then the magnesium stearate powder is screened by an air separator. However, the existing air separator cannot collect the powdered magnesium stearate filtered out, resulting in a large amount of magnesium stearate being blown to the outside, thereby causing a large amount of magnesium stearate to be wasted and causing environmental pollution. Utility Model Content

[0004] The utility model aims to solve the problem that the existing air separator cannot collect the powdered magnesium stearate under filtration, resulting in a large amount of magnesium stearate being blown to the outside, thereby causing a large amount of magnesium stearate waste and causing environmental pollution, and proposes a magnesium stearate air separation device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A magnesium stearate air separation device comprises an air separation box placed on the ground, an air inlet structure is connected through the left side of the outer wall of the air separation box, a collection structure is connected through the right side of the outer wall of the air separation box, a feed hopper is connected through the top of the air separation box, and evenly distributed slide rails are fixedly connected to the inner wall of the air separation box, and the slide rails are connected to a collection box through a screening structure.

[0007] Preferably, the screening structure comprises a coarse filter, a medium filter and a fine filter, the coarse filter is slidably connected to the slide rail, the medium filter is slidably connected to the slide rail, and the fine filter is slidably connected to the slide rail.

[0008] Preferably, the middle filter is arranged below the coarse filter, the fine filter is arranged below the middle filter, the collection box is arranged below the fine filter, and the collection box is slidably connected to the inner wall of the air separation box.

[0009] Preferably, a handle is provided on the outer wall of the air separation box, and the handle is provided on the outer walls of the coarse filter, the medium filter and the fine filter.

[0010] Preferably, the air inlet structure includes an air inlet duct, a fan, and a power supply.

The collecting pipe is connected to the right outer wall of the air separation box, the valve is fixedly connected to the collecting pipe, and the dust collecting bag is fixedly connected to the valve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the utility model is in use, magnesium stearate powder can be put into the feed hopper, and the powder can fall onto the filter plate. During the falling process, the wind blown by the fan drives the magnesium stearate powder to move toward the dust collecting bag and enter the dust collecting bag for collection, thereby preventing the magnesium stearate in the form of dust from being discharged into the air to cause waste and environmental pollution, and the agglomerated magnesium stearate powder can be taken out for easy processing, thereby greatly increasing the utilization rate of the magnesium stearate powder.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-Figure 3 A magnesium stearate air separation device comprises an air separation box 1 placed on the ground, an air inlet structure 2 is connected through the left side of the outer wall of the air separation box 1, a collecting structure 3 is connected through the right side of the outer wall of the air separation box 1, a feed hopper 4 is connected through the top of the air separation box 1, and evenly distributed slide rails 5 are fixedly connected to the inner wall of the air separation box 1, and the slide rails 5 are connected to a collection box 9 through a screening structure.

[0020] It should be noted that the specific models and specifications of the power supply 13 and the fan 12 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0021] Furthermore, the screening structure includes a coarse filter screen 6 , a medium filter screen 7 , and a fine filter screen 8 . The coarse filter screen 6 is slidably connected to the slide rail 5 , the medium filter screen 7 is slidably connected to the slide rail 5 , and the fine filter screen 8 is slidably connected to the slide rail 5 .

[0022] The pore size of the coarse filter 6 is larger than that of the medium filter 7 , and the pore size of the medium filter 7 is larger than that of the fine filter 8 .

[0023] Furthermore, the middle filter screen 7 is arranged below the coarse filter screen 6 , the fine filter screen 8 is arranged below the middle filter screen 7 , the collection box 9 is arranged below the fine filter screen 8 , and the collection box 9 is slidably connected to the inner wall of the air separation box 1 .

[0024] The height of the outer wall of the collecting box 9 is higher than the height of the inner walls of the air inlet pipe 11 and the collecting pipe 14, so that the dust falling into the pipe wall will be blocked outside the collecting box 9 to avoid confusion.

[0025] Furthermore, a handle 10 is provided on the outer wall of the air separation box 1 , and the handle 10 is provided on the outer walls of the coarse filter 6 , the medium filter 7 , and the fine filter 8 .

[0026] A handle 10 is provided so that the dust that has not passed the filtration will stay on the coarse filter 6, the medium filter 7 and the fine filter 8. We can pull the handle to take out the filter and clean and collect it.

[0027] Furthermore, the air inlet structure 2 includes an air inlet pipe 11, a fan 12, and a power supply 13. The air inlet pipe 11 is connected to the outer wall of the air separation box 1, the fan 12 is fixedly connected to the outer wall of the air inlet pipe 11, and the power supply 13 is fixedly connected to the fan 12.

[0028] The power source 13 provides power to the fan 12 , so that the fan 12 rotates and generates wind force to push the dust to the location of the collection structure 3 .

[0029] Furthermore, the collecting structure 3 includes a collecting pipe 14 , a valve 15 , and a dust bag 16 . The collecting pipe 14 is connected to the right outer wall of the air separation box 1 , the valve 15 is fixedly connected to the collecting pipe 14 , and the dust bag 16 is fixedly connected to the valve 15 .

[0030] The collecting structure 3 can control the collection of dust through the valve 15 while receiving the blown dust, so as to avoid explosion due to over-collection and the falling off of the dust bag 16.

[0031] Working principle: Put the magnesium stearate powder into the air separation box 1 through the feed hopper 4, and then turn on the power 13, so that the fan 12 rotates to generate wind force blowing toward the collection structure 3. During the process of going down, the magnesium stearate powder first contacts the coarse filter 6. At this time, the larger dust clusters will be left behind, and those that can pass through the aperture of the coarse filter 6 will fall downwards. Similarly, the magnesium stearate powder will be filtered again by the medium filter 7 and the fine filter 8, and finally fall into the collection box 9, and remain in the coarse filter 6, the medium filter 7, and the fine filter. The dust on 8 can be removed by pulling the handle 10 to remove the coarse filter 6, the medium filter 7, and the fine filter 8 and clean and collect them. Finally, after the dust bag 16 receives a certain amount of dust, we can manually control the switch of the valve 15 to avoid explosion due to over-collection and the falling off of the dust bag 16, thereby preventing the dust-like magnesium stearate from being discharged into the air to cause waste and environmental pollution, and the agglomerated magnesium stearate powder can be taken out for easy processing, which greatly increases the utilization rate of the magnesium stearate powder.
