Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bamboo pulp production, and particularly relates to an anti-deposition bamboo pulp stirring device. Background Art
[0002] Paper products are widely used in my country. Bamboo is a fast-growing herb that grows fast. As a raw material for paper pulp, it can replace wood pulp and save the use of trees. Bamboo pulp is an intermediate product for preparing paper products. During the production process of bamboo pulp, the bamboo pulp needs to be stirred to avoid stratification of bamboo fibers and solution. During the stirring process, bamboo fibers are easy to adhere or accumulate on the inner wall of the stirring device and in dead corners, affecting the quality of bamboo pulp. Utility Model Content
[0003] In response to the problems in the existing technology, the utility model provides an anti-deposition bamboo pulp stirring device, which can use inclined stirring blades to push the bamboo pulp containing a large amount of bamboo fiber at the bottom upward, so that the bamboo pulp is mixed evenly from top to bottom. At the same time, a scraper is used to scrape the dead corners of the stirring device to avoid bamboo fiber sedimentation and improve the mixing quality of the bamboo pulp.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0005] The key to the anti-sedimentation bamboo pulp stirring device is:
[0006] The mixing barrel comprises a shell, a mixing chamber and a sealing cover, wherein the shell and the sealing cover are sealed together, the top end of the shell is connected to a feed pipe, and the bottom end of the shell is connected to a discharge pipe;
[0007] The stirring mechanism includes a motor, a rotating shaft and a stirring frame installed on the rotating shaft. The stirring frame includes a stirring blade and a scraper. Two stirring blades are symmetrically arranged around the rotating shaft and have an inclined structure. The scraper is a grid plate, two of which are provided, and each scraper is arranged between two stirring blades. The outer side of the scraper is close to the inner wall of the stirring chamber, and the bottom end of the scraper is close to the bottom surface of the stirring chamber.
[0008] The stirring mechanism stirs the bamboo pulp in the stirring chamber so that the bamboo fibers are evenly mixed in the solution. The stirring blades stir the bamboo pulp in the stirring chamber and use the inclined stirring blades to rotate to flip the bamboo fibers accumulated in the lower layer upwards so that the upper and lower layers are evenly mixed. The scraper is close to the bottom and side of the stirring chamber, which is convenient for scraping the bamboo fibers on the bottom and side walls to avoid adhesion. At the same time, the grid-type scraper can break up the clumped bamboo fibers, so that the fibers in the bamboo pulp are evenly dispersed and the stirring quality is higher.
[0009] Preferably, the stirring blade is a spiral structure.
[0010] The spiral structure of the stirring blades makes it easier to flip the bamboo fibers at the bottom upwards, thereby improving the mixing efficiency.
[0011] Preferably, the scraper further includes comb teeth at the bottom end, the scraper includes a first scraper and a second scraper, and the comb teeth of the first scraper and the second scraper are staggered.
[0012] The comb teeth will not block the flow of bamboo pulp at the bottom of the stirring chamber, making it convenient for the bamboo pulp to flow out from the discharge pipe at the bottom after stirring is completed. However, there are gaps between the comb teeth and the bottom of the stirring chamber cannot be completely covered. The staggered comb teeth are used to allow the second scraper to scrape the bamboo fibers that are not scraped by the comb teeth of the first scraper, and the first scraper then scrapes the bamboo fibers that are not scraped by the comb teeth of the second scraper, thereby achieving complete coverage of the bottom surface of the stirring chamber.
[0013] Preferably, the stirring blade is 5-10 mm away from the bottom surface of the stirring chamber.
[0014] Preferably, a heating tube is further provided between the shell and the stirring chamber.
[0015] The heating tube is convenient for maintaining the appropriate temperature in the stirring chamber when the outside temperature is low.
[0016] Preferably, the connection between the bottom surface and the side surface of the stirring chamber is a rounded structure, and a cleaning brush is installed at the sharp corner of the bottom end of the scraper, and the cleaning brush contacts and cooperates with the rounded structure of the stirring chamber.
[0017] Preferably, the top end of the cleaning brush is arc-shaped to match the rounded structure.
[0018] Preferably, a valve is installed on the discharge pipe.
[0019] The beneficial effects of the present invention are as follows: the present invention adopts a stirring mechanism in combination with a stirring chamber to stir the bamboo pulp in a sealed stirring chamber to prevent dust and the like from falling into the bamboo pulp; the stirring mechanism adopts a grid-type scraper in combination with an inclined stirring blade, the scraper scrapes the bamboo fibers on the bottom and side walls of the stirring chamber to prevent the fibers in the bamboo pulp from adhering to the inner wall of the stirring chamber, and the inclined stirring blade can flip the lower layer of bamboo pulp upward when rotating to prevent the bamboo fibers and the like from settling at the bottom and causing uneven mixing of the bamboo pulp, and the scraper and stirring blade are mixed so that the bamboo fibers in the stirring chamber do not adhere to each other, the fiber contents of the upper and lower layers are close, and the bamboo fibers are mixed evenly to avoid clumping.

The stirring frame 203 includes a stirring blade 204 and a scraper 205. Two stirring blades 204 are symmetrically arranged around the rotating shaft 202 and have an inclined structure; the scraper 205 is a mesh plate, two of which are provided, and each scraper 205 is arranged between two stirring blades 204. The outer side of the scraper 205 contacts the inner wall of the stirring chamber 102, and the bottom end of the scraper 205 contacts the bottom surface of the stirring chamber 102.
[0030] During use, after adding bamboo pulp into the stirring chamber 102 from the feed pipe 104, start the motor 201 to drive the rotating shaft 202 of the stirring mechanism 2 to rotate, and the stirring frame 203 on the rotating shaft 202 rotates with the rotating shaft 202 to stir and mix the bamboo pulp in the stirring chamber 102. The stirring structure 2 includes two stirring blades 204 and two scrapers 205. The inclined stirring blades 204 can flip the bamboo fibers at the bottom of the bamboo pulp upward to prevent the fibers from accumulating at the bottom. The grid-type scraper 205 scrapes off the fibers on the inner wall of the stirring chamber 102 to prevent the fibers from adhering to the inner wall of the stirring chamber 102 and being difficult to clean. The grid structure can also break up the clumped fibers to mix the bamboo pulp evenly.
[0031] like Figure 1 、 2 As shown in Figures 3 and 5, the stirring blade 204 is a spiral structure.
