Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium carboxymethyl cellulose processing technology, specifically to a device for removing flocculent matter from conventional sodium carboxymethyl cellulose granulation products. Background Technology
[0002] Sodium carboxymethyl cellulose (CMC-Na) is an organic compound with the chemical formula [C6H7O2(OH)2OCH2COONa]n. It is a carboxymethylated derivative of cellulose and is the most important ionic cellulose gum.
[0003] After preparation, carboxymethyl cellulose has a flocculent structure and contains a certain amount of moisture. It needs to be dried to make it into a granular finished product. The existing technology directly dries the flocculent, resulting in the presence of a certain amount of flocculent material in the finished granules, which does not meet the requirements of the finished product. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a device for eliminating flocculent matter in conventional sodium carboxymethyl cellulose granulation products.
[0005] This utility model is achieved through the following technical solution: a device for removing flocculent matter from conventional sodium carboxymethyl cellulose granules is provided, comprising a granulator, a primary crusher, a dryer, and a secondary crusher arranged in sequence, wherein the flocculent sodium carboxymethyl cellulose is conveyed to the feed inlet of the granulator through a feeding device.
[0006] The flocculent sodium carboxymethyl cellulose is first granulated using the ring granulator in this scheme, then pre-crushed using a primary pulverizer, then dried in a dryer, and finally pulverized using a secondary pulverizer to achieve complete granulation.
[0007] As an optimization, the granulator is a ring-film granulator. This produces cylindrical granules, facilitating subsequent primary crushing and drying. Furthermore, the ring-film granulator offers high granulation efficiency and produces uniform granules, making it suitable for the production requirements of sodium carboxymethyl cellulose.
[0008] As an optimization, the primary pulverizer is a blade pulverizer. The blade pulverizer in this design can pulverize cylindrical granular sodium carboxymethyl cellulose into flakes, facilitating subsequent drying while ensuring the particle size of the final product.
[0009] As an optimization, the secondary crusher is a hammer mill. It has high crushing efficiency, ensuring the finished product achieves the required particle size.
[0010] As an optimization, the feeding device includes an upward-inclined primary belt conveyor, the outlet of which is located above the feed inlet of the granulator. In this design, the primary belt conveyor transports the flocculent sodium carboxymethyl cellulose upwards to the feed inlet of the granulator, achieving automatic feeding.
[0011] As an optimization, a conveying pipe connecting the primary crusher outlet and the dryer inlet is also included, wherein an upwardly inclined secondary belt conveyor is installed within the conveying pipe. In this solution, the secondary belt conveyor is used to transport the material from the primary crusher outlet to the dryer inlet, achieving automatic connection. Simultaneously, the secondary belt conveyor is positioned within the conveying pipe to prevent residual heat from the dryer from entering the conveying pipe, thereby improving drying efficiency.
[0012] As an optimization, a hygrometer is installed inside the inlet of the conveying pipe. The hygrometer in this solution can detect the air humidity at the outlet of the blade shredder, thereby roughly determining the humidity of the flaky material and controlling the drying power of the dryer.
[0013] The beneficial effects of this utility model are as follows: This utility model provides a device for eliminating flocculent matter in conventional sodium carboxymethyl cellulose granules. First, the product is granulated using a ring granulator, then pulverized into flakes using a blade pulverizer, then conveyed to a dryer for drying, and finally pulverized using a hammer mill to completely granulate it without flocculent matter, so that the finished product meets customer requirements.

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0018] like Figure 1 As shown, the present invention provides a device for removing flocculent matter from conventional sodium carboxymethyl cellulose granules, comprising a feeding device, a granulator 1, a primary crusher 2, a secondary belt conveyor 7, a dryer 3, and a secondary crusher 4 arranged in sequence. The flocculent sodium carboxymethyl cellulose is conveyed to the feed inlet of the granulator 1 through the feeding device.
[0019] All of the above components are placed on the ground. In order to achieve orderly and automatic material conveying, the feeding device includes an upward inclined primary belt conveyor 5. The outlet of the primary belt conveyor 5 is located above the feed inlet of the granulator 1. The inclination angle of the primary belt conveyor 5 is less than 30 degrees to prevent the flocculent sodium carboxymethyl cellulose from sliding down during the conveying process.
[0020] The granulator 1 is a ring-membrane granulator, which can form flocculent sodium carboxymethyl cellulose into cylindrical granules. The primary crusher 2 is a blade crusher. The outlet of the granulator 1 is located above the inlet of the blade crusher, so that the granules can directly enter the blade crusher.
[0021] Since the outlet of dryer 3 is located above the inlet of secondary crusher 4, dryer 3 is raised by columns to facilitate material transfer. In order to realize material transfer between the outlet of primary crusher 2 and the inlet of dryer 3, secondary belt conveyor 7 is set at an angle, with the inlet end of secondary belt conveyor 7 located below the outlet of primary crusher 2 and the outlet end of secondary belt conveyor 7 located above the inlet of dryer 3.
[0022] It also includes a conveying pipe 6 connecting the outlet of the primary crusher 2 and the inlet of the dryer 3, and the secondary belt conveyor 7 is installed inside the conveying pipe 6.
[0023] The inlet of the conveying pipe 6 is equipped with a hygrometer 8, which is used to detect the air humidity at that location, thereby roughly determining the humidity of the material.
[0024] The secondary crusher 4 is a hammer mill. The upper inlet of the hammer mill is located directly below the outlet of the dryer 3.
[0025] How to use this utility model:
[0026] The processed flocculent sodium carboxymethyl cellulose is conveyed upwards through a primary belt conveyor 5 to the inlet of granulator 1. It is first granulated into cylindrical particles by a ring granulator, then pulverized into flakes by a blade pulverizer. The flakes are then conveyed upwards through a secondary belt conveyor 7 (enclosed by a conveying pipe 6) to dryer 3 for drying. A hygrometer 8 detects the air humidity at the outlet of the blade pulverizer, thus providing a rough estimate of the flake material's moisture content and controlling the dryer's drying power. Finally, the dried sodium carboxymethyl cellulose is pulverized by a hammer mill to completely granulate it, eliminating any flocculent material.
[0027] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
