Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, multiple batches of colored mixed liquid are mixed into the fluidized bed granulation method, including:

[0028] Step A: Use the feed pipe connected to the inlet of the mixing tank to transport multiple batches of colored mixed dosing to the mixing tank for mixing, wherein the number of batches of colored mixed dosing is not less than 3 batches, and the colored mixed dosing is in a liquid state The mixed solution that meets the requirements of the proportion range obtained by mixing raw materials and raw material carriers. The mixing tank has the function of stirring and mixing. It is a common device on the market, and no specific introduction is given here;

[0029] Step B: using a discharge pipeline connected to the outlet of the mixing tank to transport the mixed solution to a fluidized bed for spray granulation and drying.

[0030] In this method, all batches of colored mixed liquids are uniformly mixed first, and then the unifo...

Embodiment 2

[0032] Embodiment 2: multiple batches of colored mixed liquid into the fluidized bed granulation system, such as figure 2 As shown, it includes a mixing tank connected to a plurality of feeding pipelines for transporting colored mixed liquid and a fluidized bed connected to the mixing tank through a discharge pipeline. The mixing tank is used for stirring and mixing, and the fluidized bed For spray granulation, the feed pipe is connected to the inlet of the mixing tank, and the discharge pipe is connected to the outlet of the mixing tank. In this system, all batches of colored mixed liquids are uniformly mixed, and then the uniformly mixed mixed liquid is transported to the fluidized bed for spray granulation. The color of the obtained particles is consistent, and the content of each substance in the particles is also high Within the deviation range of the target content, the granules can be directly packed into the automatic packaging line as finished products, which solves ...

Embodiment 3

[0034] Embodiment 3: Different from Embodiment 2, the system also includes a liquid level sensor arranged in the mixing tank and electrically connected to the controller, the liquid level sensor can monitor the liquid level of the mixing tank in real time, and send the liquid level signal feedback to the controller. The system also includes an alarm device electrically connected to the controller; the controller judges whether the liquid level reaches a specified limit value according to the liquid level signal, and controls the alarm device to act when the liquid level reaches the specified limit value. When the frequency conversion delivery pump fails and is out of control, the mixing tank is prone to overflow and cause production accidents. An alarm device is installed. When the liquid level reaches the specified limit value, the alarm device will activate to remind workers in time and reduce production. Accidents happen.

[0035] A plurality of the feed pipes form at leas...

Abstract

The invention relates to a method and a system for spraying and granulating a plurality of batches of colored mixed liquid into a fluidized bed. The method comprises the following steps of: A, conveying the plurality of batches of colored mixed liquid into a mixing tank for mixing by using a feeding pipeline connected with an inlet of the mixing tank; and B, conveying the mixed liquid obtained by mixing into the fluidized bed by using a discharge pipeline connected with the outlet of the mixing tank, and carrying out spraying granulation and drying. According to the invention, the problems of chromatic aberration and content deviation of particle products are solved, the market competitiveness of the products is improved, the granulation efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to a method and system for spraying and granulating multiple batches of colored mixed liquid into a fluidized bed, and belongs to the field of mixed liquid drying and granulating. Background technique [0002] Spray granulation of mixed solution on fluidized bed is an important means to obtain granular products. The mixed solution is obtained by mixing the liquid raw material and the raw material carrier. [0003] When there are multiple batches of liquid raw materials in the factory area, the traditional process is to mix a single batch of liquid raw materials with the raw material carrier and transport them to the fluidized bed for spraying and granulation drying through pipelines. After drying, the intermediate product granules obtained are mixed in multiple batches to form finished products. This is because: due to the influence of these unavoidable factors such as the carrier addition error in the mixing operation, in fact, ...
