Description

Technical Field

[0001] This utility model relates to the field of slurry preparation in a crystalline glucose production line, and in particular to a slurry preparation tank. Background Technology

[0002] In the production process of crystalline glucose, the mixing tank is a key piece of equipment for starch milk preparation. Its function is to mix starch and water to form a uniform starch milk and adjust it to a specific concentration and pH value to meet the requirements of subsequent liquefaction, saccharification and other processes.

[0003] Traditional slurry preparation processes rely on manual operation, adjusting the concentration by visual inspection and manual addition of water or starch, and then using a pH meter to test the acidity and alkalinity. This process suffers from problems such as low efficiency, poor accuracy, and uneven mixing. In addition, the uniformity of starch milk directly affects liquefaction efficiency and final product quality, but the traditional tank structure design is prone to material aggregation, which prolongs the mixing time. Utility Model Content

[0007] By adopting the above technical solution, the drive motor can simultaneously drive the stirring block and the spreading disc to rotate, so that the water is sprayed evenly in the tank, while the stirring block stirs the starch milk.

[0008] Furthermore, multiple nozzles arranged in a ring are fixedly connected to the bottom of the fabric tray, and the outer wall of the mixing block is in contact with the inner wall of the tank.

[0011] By adopting the above technical solution, the support frame fixes the liquid inlet pipe, and the annular movable block cooperates with the annular movable groove, which not only ensures the relative stability of the liquid inlet pipe and the material distribution disc, but also does not hinder the rotation of the material distribution disc.

[0012] Furthermore, the tank body and the bottom cover are connected by bolts, and the bottom of the bottom cover is fixedly connected with multiple support legs distributed in a ring.

[0013] By adopting the above technical solution, the bolts facilitate the disassembly and installation of the tank body and the bottom cover, and the support legs provide stable support for the slurry mixing tank.

[0014] Furthermore, a feed hole and a liquid inlet are provided on the top of the top cover.

[0015] By adopting the above technical solution, the feed hole facilitates the addition of starch, and the liquid inlet hole is used to introduce liquid.

[0016] Furthermore, the outer wall of the tank body and the top cover are fixedly connected by multiple connecting blocks distributed in a ring.

[0017] By adopting the above technical solution, the connecting block fixes the tank body and the top cover together.

[0018] Furthermore, a liquid outlet pipe is fixedly connected to the bottom of the bottom cover.

[0019] By adopting the above technical solution, the liquid outlet pipe is used to discharge the prepared starch milk.

[0020] Furthermore, the tank is equipped with an online pH meter and an online concentration meter, which are interlocked with the control valve on the inlet pipe for adjustment.

[0021] By adopting the above technical solution, the amount of water added can be adjusted in a chain, so that the starch milk can be adjusted to a specific concentration and pH value to meet the requirements of subsequent liquefaction, saccharification and other processes.

The drive belt 707 connects the pulley 705 and the belt groove 706 to transmit power and make the material distribution disc 5 rotate.

[0035] The bottom of the fabric tray 5 is fixedly connected to multiple nozzles 501 arranged in a ring. The nozzles 501 spray the liquid introduced by the liquid inlet pipe 4 evenly onto the starch. The outer wall of the stirring block 6 is in contact with the inner wall of the tank 1 to ensure that the stirring block 6 can fully stir the starch milk when rotating, promote the uniform distribution of water flow, and enhance the starch milk preparation effect.

[0036] A support frame 201 is fixedly connected to the top of the top cover 2. The support frame 201 is used to fix the liquid inlet pipe 4 to ensure the stability of the liquid inlet pipe 4 so that it can still enter the liquid normally when the fabric tray 5 rotates. The liquid inlet pipe 4 is fixedly installed inside the support frame 201. An annular movable block 401 is fixedly connected to the bottom of the liquid inlet pipe 4. An annular movable groove 502 is opened on the top of the fabric tray 5.
