Abstract
Description
Technical Field
[0001] This invention belongs to the field of wood cellulose sponge technology, specifically referring to the apparatus for preparing highly absorbent and biodegradable wood cellulose sponges and its usage method. Background Technology
[0002] Wood cellulose sponge is a functional material with a three-dimensional porous network structure, made from wood cellulose through a special process. It not only possesses high water absorption, enabling it to quickly absorb and retain large amounts of moisture, but also exhibits excellent biodegradability, being decomposed by microorganisms in the natural environment. This makes it environmentally friendly and gives it broad application prospects in many fields, including hygiene products, medical dressings, and oil stain absorption.
[0003] However, existing equipment for preparing highly absorbent biodegradable wood cellulose sponges suffers from numerous problems. Due to its inherent properties, the cellulose raw material is highly prone to clumping when it enters the reaction system. This clumping not only hinders the uniform wetting of the alkali solution, preventing some raw materials from fully reacting with the solution and affecting the uniformity and thoroughness of the reaction, thus reducing the performance and quality of the wood cellulose sponge, but also makes it difficult for existing equipment to prevent clumping in real time during the reaction process. This results in persistent clumping, negatively impacting both the preparation efficiency of the wood cellulose sponge and the quality stability of the final product, thus limiting the large-scale industrial production and application of highly absorbent biodegradable wood cellulose sponges.

[0014] This solution also discloses the method of using the apparatus for preparing highly absorbent and biodegradable wood cellulose sponges, which mainly includes the following steps:
[0015] Step 1: Place the dried cellulose raw material into the reaction beaker (32), put sodium hydroxide solution into the reagent storage tank (49), start the second water pump (50), and transport the sodium hydroxide solution in the reagent storage tank (49) to the reaction beaker (32) through the fourth output pipe (51). At the same time, the output end of the lifting cylinder (7) moves downward, driving the lifting plate (8) to move downward. The lifting plate (8) moves downward, driving the second output pipe (25) to move downward. The second output pipe (25) moves downward, driving the L-shaped stirring tube (26) to move downward, and moving the L-shaped stirring tube (26) into the reaction beaker (32).
[0016] Step 2: Start the motor (16). The output end of the motor (16) rotates, which drives the first bevel gear (17) to rotate. The first bevel gear (17) rotates, which drives the second bevel gear (18) to rotate. The second bevel gear (18) rotates, which drives the second output tube (25) to rotate. The second output tube (25) rotates, which drives the L-shaped stirring tube (26) to rotate. While adding sodium hydroxide solution, stir to fully wet the cellulose raw material and ensure that the cellulose raw material is completely submerged. Then start the heating resistor (12) to heat the oil in the oil chamber (11), thereby indirectly heating the reaction beaker (32).
[0017] Step 3: While stirring, open the first electronic valve (24), start the ultrasonic atomizing plate (40) and ultrasonic generator (29). The nitrogen in the nitrogen storage tank (22) enters the L-shaped stirring tube (26) through the first output pipe (23), and finally sprays out in the form of micro bubbles through the bubble stone (27). The continuous micro bubbles can break up the particle aggregation and form a slight tumbling. At the same time, the ultrasonic cavitation generated by the ultrasonic generator (29) can break up the agglomerates locally and promote the rapid penetration of the alkaline solution to prevent cellulose from agglomerating. After the reaction structure is formed, close the ultrasonic generator (29) and the first electronic valve (24). The L-shaped stirring tube (26) continues to stir. Open the second electronic valve (44) and the ultrasonic atomizing plate (40). The defoamer in the defoamer storage tank (41) flows to the ultrasonic atomizing plate (40) through the infusion pipe (43). After being atomized by the ultrasonic atomizing plate (40), it falls into the reaction beaker (32) to eliminate the foam generated when lignin and hemicellulose dissolve under alkaline conditions.
[0018] Step 4: After cooling to room temperature, open the third electronic valve (53), start the vacuum pump (34), and use the filter cotton (37) to filter the liquid in the reaction beaker (32) into the vacuum tank (33) through the connecting pipe (35). Then start the first water pump (47) to pump the deionized water in the deionized water storage tank (46) into the reaction beaker (32) and use the deionized water to wash the solid in the reaction beaker (32). Then open the third electronic valve (53) and the vacuum pump (34) again to pump the liquid into the vacuum tank (33) and wash it repeatedly. The washed cellulose raw material is then filtered and dehydrated into a paste by the vacuum pump (34) and then taken out, dried and stored.
[0019] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a device for preparing highly absorbent and biodegradable wood cellulose sponges, achieving the following beneficial effects:
[0020] (1) The physical co-processing mechanism allows the alkali solution to be added continuously during the stirring process, preventing local high alkalinity from causing excessive swelling or clumping of cellulose, thereby improving the uniformity of alkali soaking and the stability of the reaction.
[0021] (2) The physical co-processing mechanism is set up so that the L-shaped stirring tube can rotate after being vertically inserted into the reaction beaker. The stirring trajectory covers the entire beaker, breaking up the piled-up dry fibers, so that the raw materials can be quickly and completely immersed in the alkaline solution, achieving deep disturbance and no dead corner mixing, and improving the pretreatment efficiency.
[0022] (3) Nitrogen gas generates continuous microbubbles through the bubble stone. As the bubbles rise, they break up the fiber clusters and promote slight agitation of solid particles. This can significantly reduce the adhesion of dry fibers when they first encounter alkali, thereby achieving fiber dispersion and increasing the effective surface area of the reaction.
[0023] (4) The cavitation effect generated by the ultrasonic generator can locally peel off the fiber surface, promote the entry of alkali into the pores, destroy the slight agglomeration structure, and increase the removal rate of hemicellulose / lignin, making the reaction shorter and more thorough, thereby improving the removal efficiency and product purity.
[0024] (5) The defoamer forms a micro-mist through an ultrasonic atomizing plate and acts directly on the foam layer. It can quickly defoam without significantly changing the chemical composition of the system. At the same time, the dosage is much lower than that of the liquid mixing method, which greatly reduces the residue of defoamer; thus achieving precise, fast and low-interference foam control.
[0025] (6) Oil cavity heating avoids direct contact between the electric heating element and the reaction beaker, resulting in gentler heat transfer and easier maintenance of constant temperature, thus keeping the system stable and preventing local "hot spots" from degrading cellulose, thereby improving the molecular weight and mechanical property stability of the product.
[0026] (7) After the reaction is completed, the filtration and washing are carried out directly in the same reaction beaker. There is no need to pour the slurry into other containers for separation, which can reduce material loss, reduce the risk of pollution, and realize automatic filtration and circulation washing, so as to achieve continuous and compact overall process and lower labor cost.

[0049] In practical use, the dried cellulose raw material is placed into the reaction beaker 32, and sodium hydroxide solution is placed in the reagent storage tank 49.

The second electronic valve 44 and the ultrasonic atomizing plate 40 are opened, and the defoamer in the defoamer storage tank 41 flows to the ultrasonic atomizing plate 40 through the infusion pipe 43. After being atomized by the ultrasonic atomizing plate 40, it falls into the reaction beaker 32, eliminating the foam generated during the dissolution of lignin and hemicellulose under alkaline conditions. After cooling to room temperature... Open the third electronic valve 53 and start the vacuum pump 34. Use the filter cotton 37 to filter the liquid in the reaction beaker 32 through the connecting pipe 35 into the vacuum tank 33. Then start the first water pump 47 to pump the deionized water in the deionized water storage tank 46 into the reaction beaker 32. Use the deionized water to wash the solids in the reaction beaker 32. Then open the third electronic valve 53 and the vacuum pump 34 again to pump the liquid into the vacuum tank 33. Repeat the washing process several times. The washed cellulose raw material is left in suspension and filtered and dehydrated into a paste by the vacuum pump 34.

10. A method of using the apparatus for preparing highly absorbent and biodegradable wood cellulose sponges, as described in claim 9, characterized in that... The main steps include the following: Step 1: Place the dried cellulose raw material into the reaction beaker (32), put sodium hydroxide solution into the reagent storage tank (49), start the second water pump (50), and transport the sodium hydroxide solution in the reagent storage tank (49) to the reaction beaker (32) through the fourth output pipe (51). At the same time, the output end of the lifting cylinder (7) moves downward, driving the lifting plate (8) to move downward. The lifting plate (8) moves downward, driving the second output pipe (25) to move downward. The second output pipe (25) moves downward, driving the L-shaped stirring tube (26) to move downward, and moving the L-shaped stirring tube (26) into the reaction beaker (32). Step 2: Start the motor (16). The output end of the motor (16) rotates, which drives the first bevel gear (17) to rotate. The first bevel gear (17) rotates, which drives the second bevel gear (18) to rotate. The second bevel gear (18) rotates, which drives the second output tube (25) to rotate. The second output tube (25) rotates, which drives the L-shaped stirring tube (26) to rotate. While adding sodium hydroxide solution, stir to fully wet the cellulose raw material and ensure that the cellulose raw material is completely submerged. Then start the heating resistor (12) to heat the oil in the oil chamber (11), thereby indirectly heating the reaction beaker (32). Step 3: While stirring, open the first electronic valve (24), start the ultrasonic atomizing plate (40) and ultrasonic generator (29). The nitrogen in the nitrogen storage tank (22) enters the L-shaped stirring tube (26) through the first output pipe (23), and finally sprays out in the form of micro bubbles through the bubble stone (27). The continuous micro bubbles can break up the particle aggregation and form a slight tumbling. At the same time, the ultrasonic cavitation generated by the ultrasonic generator (29) can break up the agglomerates locally and promote the rapid penetration of the alkaline solution to prevent the cellulose raw material from agglomerating. After the reaction structure is formed, close the ultrasonic generator (29) and the first electronic valve (24). The L-shaped stirring tube (26) continues to stir. Open the second electronic valve (44) and the ultrasonic atomizing plate (40). The defoamer in the defoamer storage tank (41) flows to the ultrasonic atomizing plate (40) through the infusion pipe (43). After being atomized by the ultrasonic atomizing plate (40), it falls into the reaction beaker (32) to eliminate the foam generated when lignin and hemicellulose dissolve under alkaline conditions. Step 4: After cooling to room temperature, open the third electronic valve (53), start the vacuum pump (34), and use the filter cotton (37) to filter the liquid in the reaction beaker (32) into the vacuum tank (33) through the connecting pipe (35). Then start the first water pump (47) to pump the deionized water in the deionized water storage tank (46) into the reaction beaker (32) and use the deionized water to wash the solid in the reaction beaker (32). Then open the third electronic valve (53) and the vacuum pump (34) again to pump the liquid into the vacuum tank (33) and wash it repeatedly. The washed cellulose raw material is then filtered and dehydrated into a paste by the vacuum pump (34) and then taken out, dried and stored.
