Description

Technical Field

[0001] This utility model relates to the field of crushing and mixing equipment, and more specifically, to a crushing and mixing equipment for paper pulp. Background Technology

[0002] In the papermaking industry, pulp preparation is a crucial step. Paper pulp is typically composed of various fiber raw materials, such as wood, bamboo, and recycled paper, along with additives. Early pulp crushing and mixing equipment, such as simple hammer mills, placed raw materials and additives simultaneously in the mixing chamber for pounding. While this could break down the fiber raw materials to some extent, it still had certain shortcomings. For example, existing mixing equipment usually adds additives at fixed points, which may result in uneven dispersion in the pulp, causing localized differences in paper properties and quality defects such as spots and embrittlement, significantly reducing the production quality of the product. To address the shortcomings of existing technologies, we propose a paper pulp crushing and mixing device. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a paper pulp crushing and mixing equipment to solve the problem that when adding additives, the existing mixing equipment usually adds them at fixed points, which may lead to uneven dispersion in the pulp, resulting in local performance differences in paper, and quality defects such as spots and embrittlement, which greatly reduces the production quality of the product.

[0004] To solve the above technical problems, this utility model provides the following technical solution: a paper pulp crushing and mixing device, including a main body of the device, a packing assembly is provided on the upper side of the main body of the device, a crushing assembly is provided on the lower side of the packing assembly, a mixing chamber is opened in the center of the main body of the device, a guiding chamber is opened on one side of the mixing chamber, a feeding hopper is fixedly installed on the upper side of the guiding chamber on the upper outer surface of the main body of the device, and a fixing block is fixedly installed on the lower outer surface of the main body of the device;

[0005] The packing assembly includes a packing bin, a base plate is fixedly installed on the lower outer surface of the packing bin, a feed pipe is fixedly installed on the upper outer surface of the packing bin, a discharge pipe is fixedly installed on the inner wall of the base plate, a connecting pipe is rotatably connected to the inner wall of the discharge pipe, L-shaped spray pipes are symmetrically fixedly installed on the outer wall of the connecting pipe, a limit block is fixedly installed on the lower outer wall of the connecting pipe, and a limit seat is slidably installed on the outer wall of the limit block.

[0006] The base plate is detachably installed on the upper outer surface of the equipment body, and the connecting pipe is slidably installed on the inner wall of the limiting seat.

[0007] The crushing assembly includes a motor, a rotating shaft fixedly mounted on the outer surface of the motor's output end, a cutting blade fixedly mounted on the outer wall of the rotating shaft, a scraper fixedly mounted on one end of the cutting blade, a baffle provided on the lower side of the cutting blade, an electric telescopic rod fixedly mounted on the arc surface of the baffle, the motor fixedly mounted on the inner wall of the fixed block, the rotating shaft rotatably connected to the bottom of the mixing chamber, the scraper sliding on the surface of the mixing chamber, the baffle sliding on the inner wall of the main body of the equipment, the electric telescopic rod fixedly mounted on the inner wall of the main body of the equipment, and a limiting seat fixedly mounted on the top of the rotating shaft.

[0008] The upper outer wall of the connecting pipe is fixedly fitted with a limiting ring, and the limiting ring is rotatably connected to the inner wall of the discharge pipe.

[0009] The upper surface of the scraper is horizontal to one end edge of the material guiding cavity, and a fan-shaped through hole is provided at the bottom of the material guiding cavity. The area of ​​the baffle is exactly the same as that of the fan-shaped through hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes a filling assembly, including a filling chamber, to inject additives into the filling chamber through a feed pipe. A connecting pipe is then secured to the inner wall of a limiting seat via a limiting block. During crushing, the rotating shaft drives the limiting seat to rotate, which in turn drives the connecting pipe and the L-shaped spray pipe to rotate simultaneously. At this time, the L-shaped spray pipe opens, spraying the filler from the filling chamber into the mixing chamber for uniform mixing with the pulp raw materials. This structure, with the connecting pipe secured to the inner wall of the limiting seat, ensures the connecting pipe rotates with the rotating shaft, achieving uniform spraying from the L-shaped spray pipe. This results in uniform dispersion of the additives in the pulp, avoiding localized performance differences in the paper and significantly improving product quality.

[0012] This invention features a pulverizing assembly, including a motor. Starting the motor drives a rotating shaft, which in turn rotates the cutting blades and scraper. After pulverization and mixing, activating an electric telescopic rod causes a baffle to slide along the inner wall of the main body of the equipment, thereby opening the bottom of the mixing chamber and allowing the mixed slurry to flow out from the lower end. Utilizing this structure, by starting the motor and simultaneously moving the cutting blades and scraper, not only is the pulverization and mixing of raw materials achieved, but the scraper also cleans the mixing chamber, preventing slurry from adhering to its surface and facilitating equipment cleaning.

[0019] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a paper pulp crushing and mixing device, including a device body 1, a packing assembly 2 is provided on the upper side of the device body 1, a crushing assembly 3 is provided on the lower side of the packing assembly 2, a mixing chamber 4 is provided in the center of the device body 1, a guiding chamber 5 is provided on one side of the mixing chamber 4, a feeding hopper 6 is fixedly installed on the upper side of the guiding chamber 5 on the upper outer surface of the device body 1, and a fixing block 7 is fixedly installed on the lower outer surface of the device body 1.

[0021] The packing assembly 2 includes a packing bin 21. A base plate 22 is fixedly installed on the lower outer surface of the packing bin 21. A feed pipe 23 is fixedly installed on the upper outer surface of the packing bin 21. A discharge pipe 24 is fixedly installed on the inner wall of the base plate 22. A connecting pipe 25 is rotatably connected to the inner wall of the discharge pipe 24. An L-shaped spray pipe 26 is symmetrically fixedly installed on the outer wall of the connecting pipe 25. A limit block 27 is fixedly installed on the lower outer wall of the connecting pipe 25. A limit seat 28 is slidably installed on the outer wall of the limit block 27.

[0022] The base plate 22 is detachably installed on the upper outer surface of the equipment body 1, and the connecting pipe 25 is slidably installed on the inner wall of the limiting seat 28.

[0023] By connecting the connecting tube 25 to the inner wall of the limiting seat 28, the connecting tube 25 rotates with the rotating shaft 32, achieving the effect of uniform spraying of material by the L-shaped spray tube 26. This ensures uniform dispersion of additives in the slurry, avoids local performance differences in paper, and greatly improves the production quality of the product.

[0024] The crushing component 3 includes a motor 31, a rotating shaft 32 fixedly mounted on the outer surface of the output end of the motor 31, a cutting blade 33 fixedly mounted on the outer wall of the rotating shaft 32, a scraper 34 fixedly mounted on one end of the cutting blade 33, a baffle 35 provided on the lower side of the cutting blade 33, an electric telescopic rod 36 fixedly mounted on the arc surface of the baffle 35, the motor 31 fixedly mounted on the inner wall of the fixed block 7, the rotating shaft 32 rotatably connected to the bottom of the mixing chamber 4, the scraper 34 sliding on the surface of the mixing chamber 4, the baffle 35 sliding on the inner wall of the equipment body 1, the electric telescopic rod 36 fixedly mounted on the inner wall of the equipment body 1, and the limiting seat 28 fixedly mounted on the top of the rotating shaft 32.

[0025] By starting the motor 31, the cutting blade 33 and the scraper 34 move simultaneously, which not only achieves the crushing and mixing of raw materials, but also achieves the scraping of the mixing chamber 4 by the scraper 34, preventing the slurry from adhering to the surface of the mixing chamber 4, thus facilitating the cleaning of the equipment.

[0026] Among them, a limiting ring is fixedly sleeved on the upper outer wall of the connecting pipe 25, and the limiting ring is rotatably connected to the inner wall of the discharge pipe 24.

[0027] The upper surface of the scraper 34 is level with one edge of the guide cavity 5, and a fan-shaped through hole is provided at the bottom of the guide cavity 5. The area of ​​the baffle 35 is exactly the same as that of the fan-shaped through hole.

[0028] The working process of this utility model is as follows:

[0029] First, the raw materials are fed from the feed hopper 6 and slide into the mixing chamber 4 through the guide cavity 5. Simultaneously, the motor 31 is started, driving the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the cutting blade 33 and scraper 34 to rotate. The cutting blade 33 crushes and mixes the raw materials, while the scraper 34 scrapes the surface of the mixing chamber 4. This not only achieves the crushing and mixing of the raw materials but also prevents the slurry from adhering to the surface of the mixing chamber 4, thus facilitating equipment cleaning. After crushing, additives are injected from the feed pipe 23. The filler is inserted into the filling chamber 21, and then the connecting pipe 25 is clamped to the inner wall of the limiting seat 28 by the limiting block 27. During crushing, the rotating shaft 32 rotates, driving the limiting seat 28 to rotate. The rotation of the limiting seat 28 drives the connecting pipe 25 and the L-shaped spray pipe 26 to rotate simultaneously. At this time, the L-shaped spray pipe 26 is opened to spray the filler inside the filling chamber 21 into the mixing chamber 4, and mix it evenly with the pulp raw materials. This achieves the effect of uniform spraying by the L-shaped spray pipe 26, thereby realizing the uniform dispersion of additives in the pulp, avoiding local performance differences in paper, and greatly improving the production quality of the product.
