Description

Technical Field

[0001] This utility model relates to the field of starch sugar production technology, and in particular to a starch milk slurry mixing tank. Background Technology

[0002] Starch milk is a suspension made of starch and water, in which starch particles are uniformly dispersed in the water. A starch milk mixing tank is a specialized industrial device used to prepare starch milk by mixing starch and water to produce a starch milk of a specific concentration.

[0003] During the production process, starch and water are added to the mixing tank in a preset ratio, and the agitator is started to ensure that the starch and water are fully mixed to form a uniform starch slurry. At the same time, according to the requirements of the production process, the temperature of the starch slurry is adjusted by the heater and cooler, and the starch slurry is adjusted to the preset pH value. When the starch slurry is qualified, it is discharged through the outlet for the next step of processing.

[0004] Because starch granules absorb water and swell after heating, starch milk tends to increase viscosity further. If water or pH adjusters are added to the mixing tank at this time, it takes a long time for the ingredients to mix evenly. To address this issue, the inventors have proposed a novel starch milk mixing tank to improve stirring efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a starch milk mixing tank that enhances the mixing efficiency of the mixing tank when the starch milk viscosity is high.

[0006] This utility model provides a starch milk slurry mixing tank, which adopts the following technical solution:

[0007] A starch milk mixing tank includes a tank body and a stirring system. The stirring system includes a motor, a rotating shaft, a main stirring blade, and a secondary stirring blade. The motor is arranged vertically upward at the bottom of the tank body. The rotating shaft is coaxially arranged at the output end of the motor. Multiple sets of main stirring blades are evenly arranged on the surface of the rotating shaft.

[0008] The main stirring blade has a through hole on its surface, and the length direction of the through hole is consistent with the length direction of the main stirring blade. The two ends of the auxiliary stirring blade are rotatably connected to the two side walls of the through hole along its length. The inner wall of the tank is provided with a transmission assembly that drives the auxiliary stirring blade to rotate.

[0009] Preferably, the end of the auxiliary stirring blade away from the rotating shaft extends through the main stirring blade and extends in a direction away from the rotating shaft;

[0010] The transmission assembly includes a ring rack and a gear. The ring rack is horizontally fixed to the circumferential inner wall of the tank, and the gear is fixed to the end of the auxiliary stirring blade away from the rotating shaft. The ring rack and the gear are in a meshing state.

[0011] Preferably, the top of the rotating shaft extends to the outside of the tank, a cavity is formed inside the rotating shaft, the cavity extends to the top of the rotating shaft, the main stirring blade is hollow, the main stirring blade is in communication with the cavity, and a liquid outlet hole is formed on the surface of the main stirring blade.

[0012] Preferably, the liquid outlet holes are provided in multiple sets, and the multiple sets of liquid outlet holes are distributed in a ring on the wall of the through hole.

[0013] Preferably, the main stirring blade located at the bottom of the tank is connected to the bottom of the cavity.

[0017] In summary, this utility model has the following beneficial technical effects:

[0018] 1. The stirring system in this application includes a motor, a rotating shaft, a main stirring blade, and an auxiliary stirring blade. The main stirring blade is mounted on the rotating shaft, and the motor drives the rotating shaft to rotate. The main stirring blade mounted on the rotating shaft stirs the material in the tank. The surface of the main stirring blade has a through hole for placing the auxiliary stirring blade. The two ends of the auxiliary stirring blade in the length direction are rotatably connected to the opposite side walls in the length direction of the through hole. The auxiliary stirring blade is connected to the inner wall of the tank by a transmission component. When the rotating shaft rotates, the auxiliary stirring blade rotates under the action of the transmission component, thereby stirring the material.

[0019] 2. The rotating shaft in this application has a cavity inside, and the main stirring blade is hollow. The main stirring blade is connected to the cavity. That is, when the concentration or pH value of the material in the tank is pre-adjusted, the material is conveyed to the top of the rotating shaft. The material flows through the cavity and from the liquid outlet of the main stirring blade into the tank. At this time, the auxiliary stirring blade quickly stirs the material flowing out of the liquid outlet, thereby accelerating the mixing efficiency between materials.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] This utility model provides a starch milk slurry mixing tank. (See reference...) Figure 1 and Figure 2 A starch milk mixing tank includes a tank body 1 and a mixing system 2. A main feed pipe 11 is installed at the top of the tank body 1, and a discharge pipe 12 is installed at the bottom of the tank body 1. The mixing system 2 includes a motor 21, a rotating shaft 22, main mixing blades 23, and auxiliary mixing blades 24. The motor 21 is vertically and sealed at the bottom of the tank body 1, meaning the output end of the motor 21 extends into the tank body 1. The rotating shaft 22 is coaxially fixed to the output end of the motor 21, and extends vertically to the outside of the tank body 1. Multiple sets of main mixing blades 23 are arranged vertically on the shaft wall of the rotating shaft 22 located inside the tank body 1. Through holes 231 for installing the auxiliary mixing blades 24 are provided on the surface of the main mixing blades 23, and a transmission assembly 3 is provided on the inner wall of the tank body 1 to drive the auxiliary mixing blades 24 to rotate. That is, while the main mixing blades 23 are rotating and mixing, the auxiliary mixing blades 24 simultaneously rotate and mix the material inside the tank body 1, thereby enhancing the mixing efficiency.

[0026] Reference Figure 2The through hole 231 penetrates the main stirring blade 23, and the length direction of the through hole 231 is consistent with the length direction of the main stirring blade 23. The two ends of the auxiliary stirring blade 24 in the length direction are respectively rotatably connected to the two side walls in the length direction of the through hole 231. The end of the auxiliary stirring blade 24 away from the rotating shaft 22 passes through the main stirring blade 23 and extends in a direction away from the rotating shaft 22. That is, the rotating end of the auxiliary stirring blade 24 away from the rotating shaft 22 is in a state of penetrating the main stirring blade 23. The rotating end of the auxiliary stirring blade 24 away from the rotating shaft 22 is connected to the transmission assembly 3. The transmission assembly 3 includes an annular rack 31 and a gear 32. The annular rack 31 is horizontally fixedly connected to the circumferential inner wall of the tank body 1. In this embodiment, the teeth of the annular rack 31 are facing upward. The gear 32 is coaxially fixedly connected to the rotating end of the auxiliary stirring blade 24 away from the rotating shaft 22, and the gear 32 and the annular rack 31 are meshed. With the shaft 22 rotating, the main stirring blade 23 starts to rotate, and at this time the gear 32 moves on the ring rack 31, thereby driving the auxiliary stirring blade 24 to rotate.

[0027] Reference Figure 2 The rotating shaft 22 has a cavity 221 inside, which extends to the top of the rotating shaft 22. The main stirring blade 23 is hollow and is connected to the cavity 221. The surface of the main stirring blade 23 has a liquid outlet hole 232. Multiple sets of liquid outlet holes 232 are arranged in a ring on the wall of the through hole 231. At the same time, a bearing 222 is fixedly sleeved at the top of the rotating shaft 22. A pipe joint 223 is fixedly connected to the upper surface of the bearing 222. The pipe joint 223 has connecting threads on its periphery and is used to connect an external infusion pipe. During the process of adjusting the material in the tank 1, the external liquid delivery pipe is connected to the pipe joint 223 to input the adjusting material from the top of the rotating shaft 22. At this time, the material flows through the cavity 221 and the main stirring blade 23 and flows out from the liquid outlet 232. The rotating secondary stirring blade 24 plays a role in dispersing the material flowing out of the liquid outlet 232, thereby accelerating the mixing efficiency between materials.

[0028] Reference Figure 2 The annular rack 31 and the inner wall of the tank 1 have leakage holes 13, and multiple sets of leakage holes 13 are provided to allow the material on the annular rack 31 to flow down through the leakage holes 13. In this embodiment, the main stirring blade 23 located at the bottom of the tank 1 is connected to the bottom of the cavity 221, that is, the connection end of the main stirring blade 23 and the rotating shaft 22 is located at the bottom of the cavity 221, so that the material in the cavity 221 flows into the main stirring blade 23, reducing the phenomenon of material accumulation in the cavity 221.

[0029] The implementation principle of this utility model of a starch milk slurry mixing tank is as follows:

[0030] The tank 1 in this application is provided with a main conveying pipe 11, and the top of the rotating shaft 22 is provided with a pipe joint 223 for conveying and adjusting materials. When the material in the tank 1 is pre-adjusted, the adjusting material is conveyed from the pipe joint 223 into the cavity 221 of the rotating shaft 22. The adjusting material flows out from the liquid outlet 232 of the main stirring blade 23. At this time, the rotating shaft 22 is in a state of driving the main stirring blade 23 to rotate. The gear 32 moves on the ring rack 31, thereby driving the auxiliary stirring blade 24 to rotate. The joint rotation of the main stirring blade 23 and the auxiliary stirring blade 24 plays a positive role in stirring the material. The auxiliary stirring blade 24 plays a role in quickly dispersing the adjusting material flowing out from the liquid outlet 232, thereby accelerating the stirring efficiency.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
