Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder feeding, in particular to a powder feeding device which is convenient for powder dissolution. Background Art
[0002] When dissolving hygroscopic loose fine-grained powders, for example, when dissolving hygroscopic thickener powders such as carbomer, the operator is required to hold the raw material packaging bag, slowly shake off the powder from the bag mouth, and evenly and slowly sprinkle the powder into the dissolution kettle to dissolve it with the solvent (water).
[0003] When powder is shaken off manually, the amount of powder shaken off is difficult to control, and the powder easily falls on the solvent surface in piles. The surface of the powder pile can be quickly wetted by the solvent, causing the powder pile to clump in a state of being wet on the outside and dry on the inside. Not only is it difficult for the powder inside the powder pile to be dissolved in a short time, the powder pile will also block the solvent surface, preventing the subsequently shaken powder from contacting the solvent, thereby reducing the dissolution quality and dissolution speed.
[0004] In addition, because the powder is hygroscopic, it may have already agglomerated before being shaken off the bag. When the agglomerated powder falls on the surface of the solvent, only the surface of the agglomerated powder is in contact with the solvent, and the inside of the agglomerated powder is difficult to dissolve in a short period of time, which also reduces the dissolution quality and dissolution speed.
[0005] At present, in order to reduce the impact of agglomerated powders, operators are required to crush agglomerated powders while shaking off the powders. However, this method can only crush powders that have not yet touched the solvent surface, and cannot crush powders that have temporarily formed agglomerates on the solvent surface, so the dissolution quality and dissolution speed of the powders still need to be improved.
[0006] Therefore, how to improve the dissolution quality and dissolution speed is a technical problem that needs to be solved at present. Utility Model Content
[0007] In view of the above-mentioned deficiencies in the prior art, the utility model provides a powder feeding device which is convenient for powder dissolution. The utility model can improve the dissolution quality and dissolution speed.
[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0009] A powder feeding device for facilitating powder dissolution comprises a material storage structure, a three-way pipe, a first air supply pipe, an air supply structure, a venturi tube, a feeding pipe and a second air supply pipe. The material storage structure is used to store powder. The material storage structure is provided with a discharge port. The three-way pipe is provided with a first pipe port, a second pipe port and a third pipe port. The first pipe port is connected to the discharge port.

The throat section is provided with an air supply port. The feed port is connected to the third pipe port. The discharge port is connected with the feeding pipe.

The ultrasonic power box is arranged on the supporting structure, and the oscillator is arranged on the material storage structure.
[0013] Furthermore, the material storage structure adopts a storage hopper, and the bottom of the storage hopper is provided with the discharge port.
[0014] Furthermore, the air supply structure includes a pressure regulating valve, which is arranged on the material storage structure, and the first air supply pipe is connected to the air outlet of the pressure regulating valve at one end away from the second pipe opening and the second air supply pipe is connected to the air outlet of the pressure regulating valve at one end away from the air supply opening.

[0016] Furthermore, the feeding pipe is provided with a bell mouth at one end away from the discharge port.
[0017] The utility model has the beneficial effects:
[0018] 1. In the utility model, when the agglomerated powder flows through the venturi tube, the agglomerated powder is easily collided and rubbed by the wind force, so that the agglomerated powder is broken. The venturi tube can spray the powder into the solvent in a uniform mist state for dissolution. The mist state of the powder can increase the contact area between the powder and the solvent, allowing the uniform mist powder to fully contact the solvent and dissolve quickly, preventing the powder from agglomerating on the solvent liquid surface and avoiding hindering the normal dissolution of the subsequent powder. Compared with the background technology, it is beneficial to improve the dissolution quality and dissolution speed.
[0019] 2. The utility model can realize the mechanized operation of powder feeding without manual operation, which is beneficial to reducing the labor intensity of workers.
[0020] 3. The use of a mobile vehicle can flexibly adjust the position of the entire device to improve its flexibility of use.
[0021] 4. The setting of the dehumidifier can remove the water vapor in the compressed air and improve the dryness of the compressed air, so as to prevent the powder from absorbing the water vapor in the compressed air and agglomerating when the compressed air contacts the powder, thereby reducing the probability of agglomeration, which is conducive to further improving the dissolution quality and dissolution speed of the powder.
[0022] 5. The setting of the ultrasonic generator can make the powder in the storage structure receive ultrasonic vibration, thus preventing the powder from hanging on the inner wall of the storage structure.

[0036] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0037] Example:
[0038] like Figure 1 and Figure 2 As shown, a powder feeding device that facilitates powder dissolution includes a supporting structure, a material storage structure, a three-way pipe 3, a first air supply pipe 4, an air supply structure, a venturi tube 6, a feeding pipe 7, and a second air supply pipe 8.
[0039] The support structure includes a mobile vehicle 11 and a support frame 12. The support frame 12 is fixedly mounted on the mobile vehicle 11. In this embodiment, the support frame 12 can be fixed by welding, or by fasteners such as screws. By using the mobile vehicle 11, the position of the entire device can be flexibly adjusted, thereby improving the flexibility of use.
[0040] The storage structure is used to store powders, and a discharge port 21 is provided on the storage structure, and the discharge port 21 is used to allow the powders to be discharged from the discharge port 21. In this embodiment, the storage structure adopts a storage hopper 2, and the bottom of the storage hopper 2 is provided with the discharge port 21. The storage hopper 2 is fixedly mounted on the support frame 12.
[0041] The three-way pipe 3 is provided with a first pipe opening 31, a second pipe opening 32, and a third pipe opening 33. The first pipe opening 31 is connected to the discharge port 21, and the powder discharged from the discharge port 21 can enter the three-way pipe 3 through the first pipe opening 31. The second pipe opening 32 is connected to the air supply structure through the first air supply pipe 4, and the air supply structure is used to supply compressed air to the first air supply pipe 4. The compressed air from the first air supply pipe 4 enters the three-way pipe 3 through the second pipe opening 32, and blows the powder entering the three-way pipe 3 out from the third pipe opening 33. At the same time, under the blowing of this compressed air, the air pressure in the three-way pipe 3 is reduced, so that the powder in the storage hopper 2 continues to fall into the three-way pipe 3 under the action of its own weight and negative pressure, so that the powder in the storage hopper 2 can continue to enter the three-way pipe 3.
[0042] The venturi tube 6 is a pipe that contracts first and then expands, and is a vacuum generating device. The venturi tube 6 is provided with a feed port 61, a contraction section 62, a throat section 63, a diffusion section 64, and a discharge port 65 that are connected in sequence, and a gas supply port 66 is provided on the throat section 63. The feed port 61 is connected to the third pipe port 33, the discharge port 65 is connected to the feeding pipe 7, and the gas supply port 66 is connected to the gas supply structure through the second gas supply pipe 8.
[0043] The powder in the three-way pipe 3 is blown to the feed port 61 of the venturi tube 6 by the compressed air from the first air supply pipe 4, and then the powder enters the contraction section 62, the cross section of which gradually decreases, so that the flow rate of the powder is enhanced and the pressure is reduced; when the powder enters the throat section 63, the cross section of the throat section 63 is the smallest, and at this time the flow rate of the powder reaches the maximum, so that the powder is ejected. At this time, the throat section 63 also has compressed air from the second air supply pipe 8 flowing into it, so that the powder is in a uniform mist form and is sprayed to the feeding pipe 7 through the diffusion section 64 and the discharge port 65 in turn, and then sprayed into the solvent through the feeding pipe 7 for dissolution.
[0044] Because the venturi tube 6 can spray the powder in a uniform mist into the solvent for dissolution, the mist state of the powder can increase the contact area between the powder and the solvent, allowing the uniform mist powder to fully contact the solvent and dissolve quickly, preventing the powder from agglomerating on the solvent liquid surface and also avoiding interference with the normal dissolution of the subsequent powder, which is beneficial to improving the dissolution quality and dissolution speed.
[0045] Furthermore, when the agglomerated powder flows through the venturi tube 6, the agglomerated powder is easily collided and rubbed by the wind force, so that the agglomerated powder is broken up to obtain uniform mist-like powder, avoiding the agglomerated powder from directly contacting the solvent, which is also beneficial to improving the dissolution quality and dissolution speed.
[0046] Furthermore, the device can realize the mechanized operation of powder feeding without manual operation, which is beneficial to reducing the labor intensity of workers.
[0047] Furthermore, the air supply structure in this embodiment includes a pressure regulating valve 51, and the first air supply pipe 4 at one end away from the second pipe opening 32 and the second air supply pipe 8 at one end away from the air supply port 66 are both connected to the air outlet of the pressure regulating valve 51, and the pressure regulating valve 51 is fixedly mounted on the outer wall of the storage hopper 2. The pressure regulating valve 51 is used to adjust the air supply pressure.
[0048] The air supply structure also includes a dehumidifier (not shown in the figure), the air inlet of the pressure regulating valve 51 is connected to the outlet of the dehumidifier, and the inlet of the dehumidifier is connected to the compressed air device. The compressed air device and the dehumidifier are both existing technical devices, and the dehumidifier can be placed on the mobile vehicle 11. When the compressed air provided by the compressed air device (such as an air compressor) flows through the dehumidifier, the dehumidifier can remove the water vapor in the compressed air and improve the dryness of the compressed air, so that when the compressed air contacts the powder, the powder is prevented from absorbing the water vapor in the compressed air and agglomerating, thereby reducing the probability of agglomeration, thereby facilitating further improving the dissolution quality and dissolution speed of the powder.
[0049] Furthermore, since the powder is hygroscopic, the powder is easily attached to the inner wall of the storage hopper 2, forming a wall hanging. The powder hanging on the inner wall of the storage hopper 2 cannot be used, which is easy to cause waste; the powder hanging on the wall for a long time is also easy to deteriorate.
[0050] In this regard, the device further includes an ultrasonic generator. The ultrasonic generator is a prior art device. The ultrasonic generator includes an ultrasonic power supply box 91 and an oscillator 92, the ultrasonic power supply box 91 and the oscillator 92 are electrically connected, the ultrasonic power supply box 91 is fixedly mounted on the support frame 12, and the oscillator 92 is fixedly mounted on the storage hopper 2. After the ultrasonic generator is started, the powder in the storage hopper 2 can be ultrasonically vibrated to prevent the powder from forming a wall hanging phenomenon on the inner wall of the storage hopper 2.
[0051] Furthermore, the feeding pipe 7 is provided with a bell mouth 71 at one end away from the discharge port 65, and the bell mouth 71 and the feeding pipe 7 can be an integral structure. The setting of the bell mouth 71 can further increase the area of powder diffusion and further improve the dissolution speed and dissolution quality of the powder and the solvent.
[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
