Description

Technical Field

[0001] This utility model relates to a raw material preparation device for the production of non-phenolic thermosensitive colorimetric agents, belonging to the field of raw material preparation technology. Background Technology

[0002] Non-phenolic thermosensitive color developers are environmentally friendly, safe, and stable color developers, mainly used to replace traditional phenolic color developers such as bisphenol A and bisphenol S. The preparation process of non-phenolic thermosensitive color developers involves using a raw material preparation device to weigh and proportion various raw materials.

[0003] Common raw material preparation devices typically weigh the raw materials before feeding them into the container for mixing. When there are many types of raw materials, it is necessary to weigh and feed each type of raw material in turn, which leads to a longer overall cycle and affects the preparation efficiency.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a raw material preparation device for the production of non-phenolic thermosensitive color developers, which can simultaneously weigh and feed multiple raw materials, significantly improving preparation efficiency.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A raw material preparation device for the production of non-phenolic thermosensitive colorimetric reagents includes a central preparation chamber, a vacuum suction chamber connected directly above the preparation chamber, and multiple storage chambers arranged in a circular pattern around the preparation chamber. The bottoms of the storage chambers are connected to the vacuum suction chambers via lift pipes.

[0008] A weighing sensor is installed around the storage silo, and a rotary unloading valve is installed between the bottom of the storage silo and the bottom of the lifting pipe; a unloading butterfly valve a is installed between the bottom outlet of the vacuum suction silo and the preparation silo.

[0009] Furthermore, the vacuum suction chamber has multiple circumferentially distributed inlets on its walls, which are used to connect to the top of the lifting pipe.

[0010] Furthermore, multiple filter bags are evenly distributed inside the vacuum suction chamber, and the top of the filter bags is fixedly installed through a perforated plate.

[0011] Furthermore, a vacuum interface is provided at the top of the inner cavity of the vacuum suction chamber, which is connected to a vacuum blower.

[0012] Furthermore, the top side of the inner cavity of the vacuum suction chamber is connected to a high-pressure gas tank via a pipeline, and a pulse valve is installed on the pipeline.

[0013] Furthermore, a discharge butterfly valve b is installed at the bottom outlet end of the preparation chamber.

[0014] Furthermore, a vibrator a is installed on the wall of the storage silo near its outlet end.

[0015] Furthermore, a vibrator b is installed on the wall of the vacuum suction chamber near its outlet end.

[0016] Furthermore, a vibrator c is installed on the wall of the preparation chamber near its outlet end.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] Raw materials in each storage bin are sucked into the vacuum suction bin via the riser pipe. During suction, the rotary discharge valve at the bottom of the storage bin is open, and the discharge butterfly valve a at the bottom of the vacuum suction bin is closed. The mass of the raw materials is accurately measured by each weighing sensor. After suction is completed, the rotary discharge valve is closed, and the discharge butterfly valve a is open. The corresponding materials in the vacuum suction bin enter the preparation bin under the action of gravity. This allows for the synchronous feeding of different raw materials, which can significantly improve the preparation efficiency.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2As shown in the figure, this utility model provides a raw material preparation device for the production of non-phenolic thermosensitive colorimetric agents, including a central preparation chamber 1, a vacuum suction chamber 2 connected directly above the preparation chamber 1, and multiple storage chambers 5 arranged in a circular pattern around the preparation chamber 1. Each storage chamber 5 is used to store different raw materials, and the bottom of each storage chamber 5 is connected to the vacuum suction chamber 2 through a lifting pipe 4.

[0025] The vacuum suction chamber 2 has multiple circumferentially distributed inlets 3 on its chamber wall, which are used to connect to the top of the lifting pipe 4.

[0026] Multiple filter bags 9 are evenly distributed inside the vacuum suction chamber 2. The top of the filter bags 9 is fixedly installed through a perforated plate. A vacuum interface 10 is provided at the top of the inner cavity of the vacuum suction chamber 2. The vacuum interface 10 is connected to a vacuum blower, which provides power for the suction action.

[0027] The top side of the inner cavity of the vacuum suction chamber 2 is connected to the high-pressure air tank 12 via a pipeline, and a pulse valve 11 is installed on the pipeline. The pulse valve 11 is used to control the injection of compressed air to remove material from the surface of the filter bag 9.

[0028] A rotary discharge valve 6 is installed between the bottom of the storage bin 5 and the bottom of the lifting pipe 4. The rotary discharge valve 6 can supply material to the lifting pipe 4 evenly and continuously.

[0029] A weighing sensor 7 is installed around the storage silo 5. The weighing sensor 7 is used to measure the mass of the raw materials in the storage silo 5 in real time and accurately, so as to facilitate precise control of feeding.

[0030] A discharge butterfly valve a13 is installed between the bottom outlet of the vacuum suction chamber 2 and the preparation chamber 1. The discharge butterfly valve a13 is used to transport the raw materials in the vacuum suction chamber 2 to the preparation chamber 1.

[0031] A discharge butterfly valve b16 is installed at the bottom outlet end of the preparation chamber 1.

[0032] Vibrator a8 is installed on the wall of the storage silo 5 near its outlet end, vibrator b14 is installed on the wall of the vacuum suction silo 2 near its outlet end, and vibrator c15 is installed on the wall of the preparation silo 1 near its outlet end.

[0033] Vibrators a8, b14, and c15 are all used to assist in material feeding.

[0034] The specific working principle of this utility model is as follows:

[0035] Raw materials in each storage bin 5 are sucked into the vacuum suction bin 2 via the lift pipe 4. During suction, the rotary discharge valve 6 at the bottom of the storage bin 5 is open, and the discharge butterfly valve a13 at the bottom of the vacuum suction bin 2 is closed. The mass of the raw materials is accurately measured by each weighing sensor 7. After suction, the rotary discharge valve 6 is closed, and the discharge butterfly valve a13 is open. The corresponding material in the vacuum suction bin 2 enters the preparation bin 1 under gravity, thereby achieving synchronous feeding of different raw materials. Alternatively, this invention can also feed raw materials from different storage bins 5 sequentially, requiring only the opening and closing of the rotary discharge valve 6 at the bottom of the corresponding storage bin 5.
