Description

Technical Field

[0001] This utility model relates to the field of cellulose processing technology, specifically to a lancet-type cellulose granulator. Background Technology

[0002] Carboxymethyl cellulose (CMC) is a water-soluble cellulose derivative obtained by chemical modification of natural cellulose. Carboxymethyl cellulose has wide applications in the food industry, pharmaceutical industry, textile industry, oil fields, pulp and paper industry, cosmetics and other fields. It can be used as a thickener, emulsifier, stabilizer, drug sustained-release agent, pulp improver and so on.

[0003] In the production process, powdered carboxymethyl cellulose needs to be granulated. The applicant company is a professional manufacturer of carboxymethyl cellulose, and the granulator is used very frequently. The granulator achieves granulation through the combination of stirring and cutting, and water is sprayed during granulation. However, there are some problems in the current use of the granulator. The cutting blade in the granulator is a straight blade, which has a poor cutting effect on cellulose and affects the granulation efficiency. In addition, the existing granulator uses a single water inlet, which affects the granulation speed. Utility Model Content

[0007] As an optimization, a passive pulley is fixedly connected to the lower end of the stirring shaft, and a driving pulley is fixedly connected to the rotating shaft of the stirring motor.

[0008] As an optimization, the cutter is arranged in multiple rows along the length of the cutter axis, with 3-5 cutters evenly distributed in each row around the circumference.

[0009] As an optimization, the cutter shaft has an inner cavity that communicates with the water inlet pipe, a front nozzle that communicates with the inner cavity is opened at the front end of the cutter shaft, and a side nozzle that communicates with the inner cavity is opened on the side of the cutter shaft.

[0010] As an optimization, a water supply ring is fixedly connected to the outside of the granulation tank, and the cutter shaft is rotatably connected inside the water supply ring. The inner ring of the water supply ring is provided with an annular groove that communicates with the water inlet pipe, and the cutter shaft has a radial hole that communicates with the inner cavity and the annular groove.

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] like Figures 1-2 As shown, the present invention discloses a lancet-type cellulose granulator, which includes a granulation tank 1. The granulation tank 1 is a vertical circular tank with an opening at the top and a top cover 3 installed on the opening for feeding cellulose.

[0018] The bottom of the granulation tank 1 is provided with a discharge port 7 on one side, and a baffle is installed on the discharge port 7 to block the discharge port 7 during the granulation process.

[0019] The bottom of the granulation tank 1 is equipped with a stirring assembly, which includes a stirring shaft 2 and a stirring motor 11 that drives the stirring shaft 2 to rotate. The stirring shaft 2 passes vertically through the bottom plate of the granulation tank 1 and is located at the center of the granulation tank 1.

[0020] To achieve power transmission, a driven pulley 8 is fixedly connected to the lower end of the stirring shaft 2, and a driving pulley 10 is fixedly connected to the rotating shaft of the stirring motor 11. A transmission belt 9 connects the driving pulley 10 and the driven pulley 8, and the stirring motor 11 is fixed on the motor mounting plate 12.

[0021] The stirring shaft 2 is fixed with a short stirring paddle 5 and a long stirring paddle 6, both of which are in contact with the bottom surface of the granulation tank 1. In this embodiment, the stirring shaft 2 is equipped with two short stirring paddles 5 and two long stirring paddles 6, which are arranged in a staggered manner around the circumference.

[0022] An upper stirring blade 4 is fixedly connected to the upper end of the stirring shaft 2. The upper stirring blade 4 is located above the short stirring blade 5 and the long stirring blade 6. The length of the upper stirring blade 4 is less than the length of the short stirring blade 5.

[0023] The side of the granulation tank 1 is equipped with multiple cutting blade assemblies arranged circumferentially. In this embodiment, four cutting blade assemblies are provided and are evenly distributed circumferentially.

[0024] The cutter assembly includes a cutter shaft 13 and a cutter motor 15 that drives the cutter shaft 13 to rotate. The cutter shaft 13 extends radially along the granulation tank 1 and is rotatably connected to the side wall of the granulation tank 1. The rear end of the cutter shaft 13 is located outside the granulation tank 1 and is connected to the cutter motor 15 via a coupling.

[0025] Multiple cutters 14 are fixedly connected to the cutter shaft 13. The cutters 14 are arranged in multiple rows along the length of the cutter shaft 13, with 3-5 cutters 14 evenly distributed in each row around the perimeter.

[0026] The cutter 14 is a curved blade, specifically a willow leaf-shaped curved blade, to improve the cutting effect. The shape of the cutter is as follows: Figure 1 .

[0027] like Figure 2 As shown, the cutter shaft 13 has an inner cavity 23 that communicates with the water inlet pipe 21. The front end of the cutter shaft 13 has a front nozzle 16 that communicates with the inner cavity 23. Multiple front nozzles 16 are provided to increase the number of water spray points.

[0028] The cutter shaft 13 has a side nozzle 17 that communicates with the inner cavity 23. Multiple side nozzles 17 are provided so that water can be thrown out during the rotation of the cutter shaft 13.

[0029] In order to allow water from the inlet pipe 21 to enter the side nozzle 17 and the front nozzle 16, a water supply ring 19 is fixedly connected to the outside of the granulation tank 1. The water supply ring 19 is annular and the inner ring has the same diameter as the outer ring of the cutter shaft 13.

[0030] The cutter shaft 13 is rotatably connected inside the water supply ring 19. An annular protrusion is fixedly connected to the outer ring of the cutter shaft 13. A countersunk hole is opened on the end face of the water supply ring 19. The annular protrusion is located in the countersunk hole and is limited by the pressure cap 22, thus realizing the rotatable connection of the cutter shaft 13.

[0031] The inner ring of the water supply ring 19 is provided with an annular groove 20 that communicates with the water inlet pipe 21. The cutter shaft 13 has a radial hole 18 that connects the inner cavity 23 and the annular groove 20, so that water from the water inlet pipe 21 can always enter the inner cavity 23.

[0032] The method of using this utility model is as follows: Powdered cellulose is placed into granulation tank 1, stirring motor 11 and cutter motor 15 are started, water in water inlet pipe 21 enters the annular groove 20 of the inner ring of water supply ring 19, and enters the inner cavity 23 of cutter shaft 13 through radial hole 18, and then sprays out through front nozzle 16 and side nozzle 17. At the same time, the large particles are cut by the rotation of cutter 14, and finally granulation is achieved. After granulation is completed, the motor stops, the discharge port 7 at the lower end is opened, and the granular cellulose is discharged.
