Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium carboxymethyl cellulose production technology, specifically to a feeding device for sodium carboxymethyl cellulose production. Background Technology
[0002] Sodium carboxymethyl cellulose (CMC-Na) is an important water-soluble cellulose ether widely used in the food, pharmaceutical, daily chemical, petroleum, and textile industries. However, the production process of sodium carboxymethyl cellulose requires the addition of materials such as hydrochloric acid for alkalization to obtain a relatively fine and pure sodium carboxymethyl cellulose. The feeding process of raw materials such as cotton or wood pulp still requires manual intervention. The raw materials are fed in a concentrated manner and then transported to the alkalization equipment for processing. The feeding process cannot pre-treat the raw materials, resulting in low production efficiency.
[0003] Currently, the feeding of sodium carboxymethyl cellulose still requires manual intervention, and the raw materials cannot be pre-treated during feeding, resulting in low feeding efficiency. For example, a mixing device for the production of sodium carboxymethyl cellulose disclosed in CN217392297U includes a material box, which has a water chamber and a material chamber. A support frame is connected to the bottom of the material box, and a conveying mechanism is installed on one side of the support frame. A mixing cylinder is installed in the middle of the support frame, and the mixing cylinder is spaced at the bottom of the material box. The water chamber and the material chamber are respectively connected to the mixing cylinder so that the material is fed and mixed by gravity. This invention utilizes a material hopper with partitions to divide the material chamber, and designs an integrated mixing cylinder with a support frame. Material is transported via pipelines connected to the support frame. The various components are arranged in an integrated manner. During the process, water and oxygen-containing materials are injected through pipelines, with control valves on the pipelines to regulate the flow rate of the injected water and oxygen-containing materials, achieving a mixture that meets the required proportions. This quickly completes the material mixing process for use in the next production step. The structure is efficient, simple, and easy to use. However, in this design, the raw materials are not pre-treated by cutting and crushing before mixing, resulting in poor preparation quality.
[0004] Therefore, in order to address the above problems, the applicant needs to design a feeding device for the production of sodium carboxymethyl cellulose. Utility Model Content
[0005] The purpose of this invention is to provide a feeding device for the production of sodium carboxymethyl cellulose, in order to solve the problem mentioned in the background art that the raw materials for the production of sodium carboxymethyl cellulose cannot be cut and crushed during feeding, and the efficiency of conveying and initial treatment is not high.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for the production of sodium carboxymethyl cellulose, comprising a feeding device body and a feeding hopper. The feeding hopper is located directly below the bottom opening of the feeding device body. The lower opening of the feeding hopper is located directly above a first conveyor belt. A sodium addition processing chamber is located directly below the end of the first conveyor belt. A sodium addition mechanism is installed inside the sodium addition processing chamber. A second conveyor belt is installed on the same horizontal line as the sodium addition mechanism. A pyramidal feeding hopper is fixedly installed on the feeding device body. A cover plate is installed on the top of the feeding hopper. An opening is left between the cover plate and the feeding hopper for conveying raw materials.
[0007] Furthermore, a motor is installed on the main body of the feeding device, and multiple sets of blades are connected to the motor. These multiple sets of blades are located at the bottom opening of the feeding hopper.
[0008] Furthermore, a metal mesh is fixedly connected to the middle position inside the feeding hopper, and a hydraulic mechanism is installed at the corresponding position above the metal mesh. A push plate is connected to the bottom of the hydraulic mechanism, a rack is installed on the side of the push plate, and multiple insert rods are evenly installed on the bottom surface of the push plate.
[0009] Furthermore, all the inserts have the same diameter and their positions correspond to the center of the holes in the metal mesh, and the rack and the sector gear are meshed together.
[0010] Furthermore, the sector gear is mounted on a rotating rod, which is rotatably connected to the inside of the feeding hopper, and a baffle is also connected to the rotating rod.
[0011] Furthermore, the length of the baffle is adapted to the length of the push plate, and the area of the push plate is adapted to the area of the metal mesh.
[0012] Furthermore, the first conveyor belt is inclined upwards, and the conveying end of the first conveyor belt corresponds to the setting position of the sodium addition treatment chamber, while the second conveyor belt is set horizontally, and the conveying start end extends into the sodium addition treatment chamber.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention utilizes a feeding hopper installed on the main body of the feeding device and a metal mesh installed inside the feeding hopper. A hydraulic mechanism, a push plate, and a bottom insert rod continuously move towards the center of the metal mesh holes, preferentially cutting off the coarse fibers of the raw materials. As the push plate moves downward, it drives the rotation of the rack and sector gear, causing the baffle to flip and continuously convey the raw materials directly below the push plate, thus improving the efficiency of conveying and initially cutting the raw material fibers.
[0015] The raw materials, whose fibers have been initially cut, are further crushed by a motor installed on the feeding device and multiple sets of blades connected to the motor. After being crushed, the raw materials are conveyed to the sodium-adding mechanism via a conveyor belt. After being treated with sodium, they are conveyed to the next production line via a second conveyor belt, thereby improving the efficiency of raw material conveying and the efficiency of crushing the raw materials during the conveying process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-5As shown, the present invention discloses a feeding device for the production of sodium carboxymethyl cellulose, comprising a feeding device body 1 and a feeding hopper 2. The feeding hopper 2 is located directly below the bottom opening of the feeding device body 1. The lower opening of the feeding hopper 2 is located directly above the first conveyor belt 10. A sodium addition chamber 11 is located directly below the end of the first conveyor belt 10. A sodium addition mechanism 12 is installed inside the sodium addition chamber 11. A second conveyor belt 13 is installed on the same horizontal line as the sodium addition mechanism 12. A pyramidal feeding hopper 2 is fixedly installed on the feeding device body 1. A cover plate is installed on the top of the feeding hopper 2. An opening is left between the cover plate and the feeding hopper 2 for conveying raw materials.
[0024] Raw materials are conveyed from the feed hopper 2, initially crushed, then crushed a second time, and conveyed to conveyor belt 10 until they are conveyed from conveyor belt 2 to the next production line.
[0025] A motor 102 is installed on the main body 1 of the feeding device. Multiple sets of blades 101 are connected to the motor 102. The multiple sets of blades 101 are set at the bottom opening of the feeding hopper 2. A metal mesh 201 is fixedly connected in the middle of the feeding hopper 2. A hydraulic mechanism 3 is installed at the position corresponding to the metal mesh 201. A push plate 4 is connected to the bottom of the hydraulic mechanism 3. A rack 401 is installed on the side of the push plate 4. Multiple insert rods 5 are evenly installed on the bottom surface of the push plate 4.
[0026] When the raw material is conveyed from the feed hopper 2, it is pushed by the push plate 4 and squeezed into multiple metal meshes 201. During the extrusion process, the coarse fibers of the raw material are initially cut off.
[0027] All the insert rods 5 have the same diameter and their positions correspond to the center of the holes in the metal mesh 201. The rack 401 is meshed with the sector gear 7, which is mounted on the rotating rod 6. The rotating rod 6 is rotatably connected to the feeding hopper 2. A baffle 8 is also connected to the rotating rod 6. The length of the baffle 8 is adapted to the length of the push plate 4, and the area of the push plate 4 is adapted to the area of the metal mesh 201.
[0028] Conveyor belt 10 is inclined upwards, and the end of conveyor belt 10 corresponds to the position of sodium addition treatment chamber 11, while conveyor belt 2 13 is horizontally set, with the starting end of conveying extending into sodium addition treatment chamber 11.
[0029] As the push plate 4 moves up and down continuously, it drives the insert rod 5 to push into the holes of the metal mesh 201. This causes the rack 401 and the sector gear 7 to mesh and rotate continuously, which in turn causes the baffle 8 to flip continuously. This results in the raw materials being continuously conveyed downwards from the push plate 4, improving the efficiency of downward conveying and cutting.
[0030] Working principle: First, the raw material (cotton or wood pulp) is pushed into the metal mesh 201 by the push plate 4 and the insert rod 5 continuously pushed from the feed hopper 2. Under the action of the metal mesh 201, the fibers in the cotton or wood pulp are initially broken, and then it is transported to the blade 101 to be completely crushed, and then it falls from the feed bin 9.
[0031] After being conveyed by conveyor belt 10, the semi-finished fiber is subjected to sodium addition treatment in sodium addition treatment chamber 11. After being treated, the semi-finished fiber is conveyed along conveyor belt 2 to the next process production line.
[0032] As the push plate 4 is continuously pushed downwards, it drives the rack 401 to move up and down, causing the sector gear 7 to rotate continuously. This causes the baffle 8 to continuously flip from a state that is close to the inner side of the feed hopper 2 to a state that is opposite to the metal mesh 201. (The rotation angle of the baffle 8 is within 60°, and the flip angle is fixed according to the height of the push plate 4. The height of the push plate 4 is the distance from the top of the feed hopper 2 to the metal mesh 201.)
[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
