Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate depolymerization technology, specifically to a device for depolymerizing light calcium carbonate. Background Technology

[0002] Light calcium carbonate is an ultrafine calcium carbonate powder produced through chemical synthesis. It is characterized by small particle size, large specific surface area, and poor dispersibility, making it prone to agglomeration, which affects its application performance in plastics, rubber, coatings and other fields. The function of the deagglomeration device is to break the agglomeration structure of light calcium carbonate particles through mechanical force, airflow impact, ultrasonic vibration and other methods, so as to disperse them into finer and more uniform individual particles, thereby improving the dispersibility and performance of the powder.

[0003] When using this light calcium carbonate depolymerization device, excessively high rotation speed or excessively long residence time may cause the particle size to be smaller than the target value, thereby affecting the product's bulk density and oil absorption value, leading to abnormal performance in downstream applications. At the same time, iron filings generated by component wear may mix into the powder, potentially causing the iron content of food-grade calcium carbonate to exceed the standard, affecting product compliance. Utility Model Content

[0004] The purpose of this invention is to provide a light calcium carbonate depolymerization device to address the issues raised in the background art, such as excessively high rotation speed or excessively long residence time during use, which may cause particle size to be smaller than the target value, thereby affecting the product's bulk density and oil absorption value, leading to abnormal performance in downstream applications. Additionally, iron filings generated from component wear may mix into the powder, potentially causing excessive iron content in food-grade calcium carbonate, affecting product compliance. To achieve the above objectives, this invention provides the following technical solution: a light calcium carbonate depolymerization device, including a workbench;

[0005] A transmission assembly includes a connecting pipe, a feed pipe fixedly connected to the side surface of the connecting pipe, a feed port opened at the top of the feed pipe, a sealing gasket fixedly connected to the side surface of the connecting pipe, a fixed bracket fixedly connected to the side surface of the connecting pipe, the bottom of the fixed bracket fixedly connected to the top of the worktable, a protective shell fixedly connected to one end of the connecting pipe, the sealing gasket located at the connection between the connecting pipe and the protective shell, a heat dissipation hole fixedly connected to the top of the protective shell, separation ports opened on both sides of the protective shell, the two separation ports being symmetrically distributed on both sides of the protective shell, and a depolymerization assembly disposed inside the protective shell.

[0006] More preferably, the depolymerization component includes an arc-shaped cover plate, which is fixedly connected to the inside of the protective shell, one end of the connecting pipe is fixedly connected to the depolymerization pipe, and a placement rack is fixedly connected to the inside of the protective shell.

[0007] More preferably, a plurality of heating tubes are fixedly connected inside the protective shell, and the heating tubes are arranged in a ring array inside the protective shell. A stirring auger is fixedly connected inside the depolymerization tube. Light calcium carbonate is put into the feed port and simultaneously enters the depolymerization tube inside the connecting pipe through the feed pipe. At the same time, the drive motor is started, so that the drive motor drives the stirring auger to rotate. During the rotation, the stirring auger gradually depolymerizes the light calcium carbonate, and the heating tubes heat it, so that the light calcium carbonate can be depolymerized more easily. The impurities generated by depolymerization are separated from the separation port.

[0008] Preferably, the other end of the depolymerization tube is fixedly connected to a discharge pipe, the side surface of the discharge pipe is fixedly connected to a discharge pipe, and the side surface of the discharge pipe is fixedly connected to a protective bracket. At the same time, the heat dissipation holes are used to dissipate heat during depolymerization, thereby avoiding excessive rotation speed or excessive residence time, which may cause the particle size to be smaller than the target value, thus affecting the product's bulk density and oil absorption value, leading to abnormal performance in downstream applications. In addition, iron filings generated by component wear may mix into the powder, which may cause the iron content of food-grade calcium carbonate to exceed the standard, affecting product compliance.

[0009] More preferably, the bottom of the protective bracket is fixedly connected to the top of the workbench, and the top of the workbench is provided with a discharge port, which is located at the bottom of the discharge pipe.

[0010] More preferably, a fixed frame is fixedly connected to the bottom of the workbench, and several support legs are fixedly connected to the bottom of the fixed frame. The support legs are symmetrically distributed at the bottom of the fixed frame. A support frame is fixedly connected to the top of the workbench. After processing, light calcium carbonate enters the discharge pipe from the discharge pipe. At the same time, a collection box is placed in advance at the bottom of the discharge port to collect the depolymerized light calcium carbonate. During use, the device is supported by the support legs and can also be moved by casters, thus giving the device high stability and flexibility.

[0011] More preferably, a connecting frame is fixedly connected to the top of the support frame, and a drive motor is fixedly connected to the top of the connecting frame. The transmission end of the drive motor is connected to the stirring auger.

[0012] More preferably, the bottom of the fixing frame is fixedly connected to four casters, and the four casters are symmetrically distributed at the bottom of the fixing frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, light calcium carbonate is fed into the feed inlet and simultaneously enters the depolymerization tube within the connecting pipe through the feed pipe. At the same time, the drive motor is activated, causing the stirring auger to rotate. During rotation, the stirring auger gradually depolymerizes the light calcium carbonate. Simultaneously, heating is provided by the heating tube, facilitating the depolymerization process. Impurities generated during depolymerization are separated from the separation port. Heat dissipation holes are used to dissipate heat during depolymerization, preventing excessively high rotation speeds or prolonged residence times, which could result in particle sizes smaller than the target value, affecting the product's bulk density and oil absorption value, leading to abnormal performance in downstream applications. Furthermore, iron filings from component wear may mix into the powder, potentially causing excessive iron content in food-grade calcium carbonate, affecting product compliance.

[0015] In this invention, after processing, light calcium carbonate enters the discharge pipe from the discharge pipe. At the same time, a collection box is placed at the bottom of the discharge port to collect the depolymerized light calcium carbonate. During use, the device is supported by support legs and can also be moved by casters, thus giving the device high stability and flexibility. Attached Figure Description
