Technical Field

Background

In the fields of industry, food, etc., slurry is generally obtained by mixing solid powder and liquid using a slurry-making apparatus.

The extending direction of the liquid injection channel 303 is parallel to the axial direction X of the pulping barrel 10, so that the liquid material can smoothly flow to the mixing cavity 701 along the extending direction of the liquid injection channel 303, and the blanking rate of the liquid material is improved. The solid-liquid mixing structure 70 forms the negative pressure after rotating, and powder and liquid material can flow towards the bottom of the mixing cavity 701 under the action of negative pressure, so that the reflux of powder and liquid material is reduced, the infiltration efficiency of powder and liquid material is improved, the scattering phenomenon generated when the powder falls is avoided, and the blanking efficiency and pulping quality are further improved.

The inner chamber 101 of the pulp drum 10 further comprises a discharge chamber 702. The discharge cavity 702 is communicated with the mixing cavity 701 and the discharge port 104. Illustratively, in the present embodiment, a discharge cavity 702 is further formed between the flow guiding member 30 and the liquid material dispersing structure 50 and the solid-liquid mixing structure 70, which is in communication with the discharge port 104 and the mixing cavity 701. The discharge cavity 702 and the diversion channel 301 are arranged in a separated manner in the radial direction Y of the pulping barrel 10, so that the problem that the liquid material dispersed by the liquid material dispersing structure 50 flows upwards and directly flows out towards the discharge port 104 without being infiltrated and mixed with powder is avoided, and further the liquid material dispersed by the liquid material dispersing structure 50 can be infiltrated and mixed with the powder more, and the powder discharging rate and the pulping quality are improved. Illustratively, in this embodiment, the discharge chamber 702 is disposed around the outside of the mixing chamber 701, and the diversion channel 301 is located on a side of the discharge chamber 702 facing away from the mixing chamber 701.

The liquid material dispersing cavity 501, the diversion channel 301, the mixing cavity 701 and the discharging cavity 702 are sequentially communicated and form the pulping flow passage 105. Illustratively, in the present embodiment, the arrow direction in fig. 2 represents the material flow direction of the pulping flow path 105. For example, the liquid material enters the liquid material dispersing cavity 501 from the liquid inlet 102, enters the diversion channel 301 after being dispersed by the liquid material dispersing structure 50 and flows into the mixing cavity 701, the powder material enters the powder material dispersing cavity 110 and enters the mixing cavity 701 through the powder inlet 103, the liquid material and the powder material are wet mixed in the mixing cavity 701 to form slurry, and the slurry is discharged to subsequent equipment through the discharging cavity 702, so that the pulping work is completed. Since the liquid material is fed in a lower feeding manner, the dispersing capability of the liquid material dispersing structure 50 is fully utilized, so that the liquid material dispersing cavity 501 is dispersed to reach a filling state, and the dispersing efficiency of the liquid material is improved. The liquid passing through the liquid dispersion cavity 501 can flow upwards to the upper part of the mixing cavity 701 along the diversion channel 301 at the outer side of the pulping barrel 10, and the liquid in the mixing cavity 701 is mixed with the powder in a liquid curtain manner, so that the powder discharging efficiency and the soaking efficiency are improved, and the pulping quality is further improved.

The discharge opening 104 penetrates the inner and outer side walls of the pulp drum 10. The pulping apparatus 100 further comprises a discharge conduit 40. The discharge conduit 40 communicates with the discharge chamber 702 through the discharge port 104. Illustratively, in the present embodiment, the position of the guide member 30 corresponding to the discharge opening 104 is provided with an opening 304 in communication with the discharge opening 104. A discharge conduit 40 is disposed between the opening 304 and the discharge port 104 in communication with the discharge chamber 702. The discharge duct 40 and the diversion channel 301 are disposed independently of each other. The discharging pipeline 40 penetrates through the discharging hole 104 and extends to the opening 304 on the flow guiding piece 30, so that the problems of poor wetting effect and long discharging time caused by that liquid material is directly discharged from the discharging hole 104 without being mixed with powder material in a wetting manner are avoided.

Illustratively, in the present embodiment, the baffle 30 includes a first baffle 31 and a second baffle 32.

The first current collector 31 and the second current collector 32 are sequentially arranged along the axial direction X of the pulping barrel 10. The first flow channel 310 is closer to the liquid dispersion chamber 501 than the second flow channel 320. As can be appreciated, because the liquid material dispersed by the liquid material structure flows from bottom to top, under the action of gravity, the dispersed liquid material is closer to the second flow channel 320, and the flow channel resistance is larger, the embodiment of the application is smaller than the second size based on the design of the first size, so that the dispersed liquid material can smoothly and quickly enter the mixing cavity 701 to be mixed with the powder material in a soaking manner, the flow loss is small, and the flow property of the liquid material is improved. The cross section of the first flow channel 310 and the cross section of the second flow channel 320 refer to the cross sections of the first flow channel 310 and the second flow channel 320 perpendicular to the circumferential direction Z of the pulping barrel 10. The first dimension refers to the distance between the first current collector 31 and the side plate 13 of the drum 10 in the radial direction Y of the drum 10, and the second dimension refers to the distance between the second current collector 32 and the side plate 13 of the drum 10 in the radial direction Y of the drum 10.

Illustratively, in the present embodiment, the second conduction port 503 is opened at an end of the fixing ring 513 away from the stator plate 511. Therefore, based on the fact that the second diversion port 503 is disposed at the upper portion of the fixing ring 513 away from the stator disc 511, on one hand, the liquid material is correspondingly disposed at the middle upper portion of the liquid material dispersing cavity 501, so that the liquid material can be dispersed more fully, and some liquid material is prevented from flowing away from the second diversion port 503 without being dispersed, and the liquid material dispersing efficiency is improved; on the other hand, the second diversion opening 503 is closer to the diversion channel 301, so that the flow path of the liquid material in the diversion channel 301 is shortened, the liquid material has smaller fluid resistance, and the fluidity is improved.

In some embodiments, the second conduction opening 503 is offset from the discharge opening 104 in the circumferential direction Z of the pulp drum 10.

The liquid material dispersing structure 50 further includes a partition 53. The partition 53 is provided between the solid-liquid mixing structure 70 and the dispersing rotor 52, and serves to partition the liquid material dispersing chamber 501 and the mixing chamber 701.

Therefore, the resistance of the labyrinth channel 506 is larger, so that only a very small part of liquid material flows into the upper gap 505 from the labyrinth channel 506, and the small part of liquid material can infiltrate a small amount of powder material entering the gap 505, thereby avoiding the problems that the powder material is not infiltrated, the friction is larger, and the pulping equipment 100 is damaged; on the other hand, most liquid materials can enter the powder inlet 103 through the flow guide channel 301, so that powder is better infiltrated, and the powder discharging efficiency is improved. In some embodiments, labyrinth passage 506 may be generally, but not limited to, semi-circular saw tooth, sinusoidal, etc.

Specifically, in the present embodiment, the partition 53 is rotatably connected to the dispersing stator 51, so that the dispersing stator 51 is rotated following the rotation shaft. The partition 53 and the dispersing stator 51 are disposed at intervals in the axial direction X of the pulping barrel 10 to improve the smoothness of rotation of the dispersing rotary shaft. Illustratively, the side of the partition 53 facing the dispersing stator 51 is provided with a plurality of first guide grooves 531 arranged at intervals in the radial direction Y of the pulping barrel 10.
