Description

Technical Field

[0001] The invention relates to the technical field of sodium hydroxide ethanol solution mixing equipment, in particular to a sodium hydroxide ethanol solution mixing equipment for processing carboxymethyl cellulose. Background Art

[0002] In the production process of carboxymethyl cellulose, sodium hydroxide (NaOH) is a key reactant, and its processing efficiency and quality directly affect the quality of the final product. Especially when mixed with ethanol solution, the particle size, distribution uniformity and dissolution rate of sodium hydroxide are crucial for the subsequent alkalization reaction and etherification reaction. However, in the existing technology, the pre-crushing and rolling of sodium hydroxide often faces some inconveniences and challenges.

[0003] Traditional mixing equipment often lacks an efficient pre-crushing mechanism for sodium hydroxide, resulting in different sizes of sodium hydroxide particles and uneven dissolution rates during the mixing process, which in turn affects the uniformity and reaction efficiency of the reaction system. This not only increases the reaction time, but may also cause side reactions due to excessive or low local concentrations, affecting the quality of the carboxymethyl cellulose. In addition, as a strong base, sodium hydroxide dust poses a health risk to operators and is prone to moisture absorption and agglomeration, further increasing the difficulty of handling. Therefore, it is particularly important to fully pre-crush and roll the sodium hydroxide before mixing to reduce particle size, increase dissolution rate and mixing uniformity. Chinese Patent Publication No. CN219051049U discloses a stirring device for sodium hydroxide production which is easy to maintain. The device is provided with an adjustment component and a stirring component. The driving motor drives the stirring blade and the scraper to rotate. The stirring blade can stir and mix the sodium hydroxide raw material in the tank body, and the rotation of the scraper can scrape off the sodium hydroxide raw material attached to the inner wall of the tank body to prevent it from sticking to the inner wall of the tank body. When the inner wall of the tank body and the stirring blade are decomposed and cleaned, the user can rotate the rotating rod to drive the tank body to rotate to about ninety degrees, so that the tank body is changed from a vertical state to a horizontal state, and then the card is moved up to insert into the card sleeve, and then the screw is rotated, so that the card drives the card sleeve to move right, and finally drives the components on the top cover to move right, and finally the driving motor, the stirring blade and the scraper are separated from the tank body, and then the tank body, the stirring blade and the scraper are decomposed and cleaned.

[0004] However, in actual use, the above structure is not convenient for pre-processing and crushing of sodium hydroxide, resulting in different sizes of sodium hydroxide particles entering the stirring tank, and some particles are too large to be quickly dissolved in the ethanol solution. Therefore, during the stirring process, the decomposition rate of sodium hydroxide is limited, and the concentration uniformity required for the reaction cannot be quickly achieved, thereby prolonging the overall stirring and mixing time.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] See also Figure 1 and Figure 2As shown, a sodium hydroxide ethanol solution mixing device for processing carboxymethyl cellulose includes a base 1, a stirring tank 2 arranged on the base 1, a stirring roller 3 installed on the stirring tank 2 for uniformly stirring and mixing the materials in the stirring tank 2, a rotating driver 31 arranged on the stirring tank 2 for driving the stirring roller 3 to rotate, a feed box 4 arranged on the stirring tank 2, and a pretreatment mechanism 5 arranged on the stirring tank 2 for rolling the materials in the feed box 4, the pretreatment mechanism 5 includes a rotating rolling roller 51 and a rotating driving mechanism 6 for driving the rotating rolling roller 51 to rotate and roll, the sodium hydroxide ethanol solution mixing device for processing carboxymethyl cellulose also includes a mixing mechanism 7 arranged in the stirring tank 2 and used to stir the treated materials to prevent stratification, and the outer wall of the stirring tank 2 is provided with a plurality of heating mechanisms for heating the materials in the stirring tank 2. Block 21, a temperature control sensor 22 for detecting the temperature in the stirring tank 2 is provided on the stirring tank 2, and a controller 23 for controlling the temperature of the heating block 21 is provided on the stirring tank 2. After the controller 23 detects the temperature in the stirring tank 2, it transmits a heating signal to the temperature control sensor 22, and the temperature control sensor 22 transmits a signal to the heating block 21, thereby uniformly stirring and heating the materials stirred and mixed in the stirring tank 2, so that the mixing efficiency of sodium hydroxide and ethanol is higher and more uniform. Heating can reduce the viscosity of ethanol and increase the molecular movement speed, thereby promoting the dissolution of sodium hydroxide in ethanol. A feeding pipe 24 is provided on the stirring tank 2, and ethanol can flow into the stirring tank 2 through the feeding pipe 24 and be uniformly mixed with the crushed sodium hydroxide. A discharge valve is provided on the stirring tank 2 to discharge the mixed sodium hydroxide and ethanol in a centralized manner.

[0035] When sodium hydroxide and ethanol need to be mixed, the sodium hydroxide is first put into the feed box 4, and then the rotary driver 31 is started and drives the stirring rod connected thereto to rotate. During this process, the stirring rod can drive a plurality of rotating crushing rollers 51 to crush and crush the sodium hydroxide, thereby preventing the sodium hydroxide from having a poor mixing effect with the ethanol due to its large shape during the mixing process.

[0036] See also Figure 2-Figure 5 As shown, the rotary drive mechanism 6 includes a mounting block 61, a fixed gear ring 62, a processing sleeve 63 and a through hole 64; the mounting block 61 is arranged on the mixing tank 2 and is located below the feed box 4; the fixed gear ring 62 is arranged on the mounting block 61; the processing sleeve 63 is arranged on the mixing tank 2, and the processing sleeve 63 is located below the fixed gear ring 62, and the processing sleeve 63 is used to support the material; a plurality of through holes 64 are provided on the processing sleeve 63 for the crushed material to pass through.

[0037] First, sodium hydroxide is added through the feed box 4. After the addition, the material can evenly fall on the processing sleeve 63, and then the rotary driver 31 is started and drives the stirring rod to rotate. When the stirring rod rotates, the rotary rolling roller 51 can be driven to rotate along the fixed gear ring 62, and the sodium hydroxide remaining on the processing sleeve 63 is rotated and evenly rolled to grind the sodium hydroxide into powder. The powdered sodium hydroxide can be discharged through the through hole 64 provided on the processing sleeve 63, and fall into the stirring tank 2 to be mixed and stirred with ethanol. The sodium hydroxide is initially crushed and crushed by the pretreatment mechanism 5, which can increase the contact area between the sodium hydroxide and the ethanol, thereby facilitating the mixing of the sodium hydroxide and the ethanol.

[0038] See also Figure 2-Figure 7 As shown, the rotary drive mechanism 6 also includes a dividing plate 65, a fixed sleeve 66, a rotating rod 67 and a gear 68; the dividing plate 65 is arranged on the stirring rod and has a plurality of them, and the dividing plate 65 is used to evenly divide the material put into the feed box 4; the fixed sleeve 66 is arranged on the stirring rod and is coaxially fixed with the stirring rod; the rotating rod 67 is rotatably arranged on the fixed sleeve 66, and the rotating rod 67 is coaxially fixed with the rotating rolling roller 51; the gear 68 is arranged on the rotating rod 67 and is coaxially fixed with the rotating rod 67, and the gear 68 is meshed with the fixed gear ring 62.

[0039] When the stirring rod rotates, it can drive the dividing plate 65 and the fixed sleeve 66 to rotate. When the dividing plate 65 rotates, the sodium hydroxide can be evenly distributed and processed. The sodium hydroxide after distribution can fall onto the processing circular sleeve 63, and then the fixed sleeve 66 drives the rotating rod 67 to rotate. When the rotating rod 67 rotates, the coaxially fixed gear 68 can be rotated. Since the gear 68 is meshed with the fixed gear ring 62, the gear 68 and the rotating rod 67 can be uniformly rotated. When rotating, the coaxially fixed rotating crushing roller 51 can be rotated, and then the rotating crushing roller 51 can be rotated and the sodium hydroxide can be evenly crushed.

[0040] See also Figure 6 and Figure 7 As shown, the rotary drive mechanism 6 also includes a raised rolling block 69 and a cleaning plate 691; the raised rolling block 69 is arranged on the rotary rolling roller 51 and has a plurality of them, and the raised rolling block 69 is used to squeeze the material; the cleaning plate 691 is arranged on the fixed sleeve 66 and contacts with the processing circular sleeve 63, and the cleaning plate 691 is used to scrape off the material adhered and accumulated on the processing circular sleeve 63.

[0041] When the fixed sleeve 66 rotates and the rotating rolling roller 51 contacts the sodium hydroxide, a plurality of raised rolling blocks 69 provided on the rotating rolling roller 51 may contact and squeeze the sodium hydroxide. The diameter of the raised rolling block 69 is larger than the diameter of the through hole 64, so that the sodium hydroxide attached to the through hole 64 can be effectively crushed. When the fixed sleeve 66 rotates, the cleaning plate 691 may be driven to effectively scrape and clean the sodium hydroxide accumulated on the processing circular sleeve 63, so as to effectively avoid the accumulation of sodium hydroxide on the processing circular sleeve 63 and cause waste of raw materials.

[0042] See also Figure 8-Figure 10 As shown, the mixing mechanism 7 includes a sliding sleeve 71, a docking block 72 and a swing mixing plate 73; the sliding sleeve 71 is vertically slidably arranged on the stirring rod and has a pair; the docking block 72 is arranged on the sliding sleeve 71 and has a plurality of them; the swing mixing plate 73 is rotatably arranged on the docking block 72 and has a plurality of them, and the swing mixing plate 73 is used to uniformly stir the material in the stirring tank 2.

[0043] When the crushed sodium hydroxide falls into the stirring tank 2, the stirring rod rotates to drive the sliding sleeve 71 that slides with it in the vertical direction to rotate synchronously, and during the rotation of the sliding sleeve 71, it can drive several swing mixing plates 73 that are rotated externally to evenly mix and stir the sodium hydroxide and ethanol.

[0044] See also Figure 2-Figure 11 As shown, the mixing mechanism 7 also includes a first limiting groove 74, a second limiting groove 75 and a sliding block 76; the first limiting groove 74 is opened on the inner wall of the mixing tank 2; the second limiting groove 75 is opened on the inner wall of the mixing tank 2 and is located below the first limiting groove 74, and the second limiting groove 75 and the first limiting groove 74 are arranged inversely to each other; the sliding block 76 is arranged on the swing mixing plate 73, and the sliding block 76 is respectively located in the first limiting groove 74 and the second limiting groove 75 for sliding, the sliding block 76 is a round sphere, and the swing mixing plate 73 is provided with a damping spring 761 for lifting the sliding block 76 to always contact the first limiting groove 74 and the second limiting groove 75, so as to prevent the sliding block 76 and the swing mixing plate 73 from being separated from the first limiting groove 74 and the second limiting groove 75.

[0045] When the stirring rod rotates, the sliding block 76 provided on the swing mixing plate 73 can slide and rotate along the first limiting groove 74 and the second limiting groove 75 opened on the inner wall of the stirring tank 2, and the first limiting groove 74 and the second limiting groove 75 are mutually guided and in an inverted eight shape, which makes the swing mixing plate 73 rotate and swing evenly, increases the rotation stirring range of the swing mixing plate 73 in the stirring tank 2, avoids the fixing of the position of the swing mixing plate 73 during stirring, prevents the stratification phenomenon during the mixing process of sodium hydroxide and ethanol, and avoids the uneven local dissolution effect.

[0046] See also Fig. 9 and Fig.10 As shown, the mixing mechanism 7 further includes a positioning rod 77 and a connecting piece 78 ; the positioning rod 77 is disposed on the mounting block 61 and has a plurality of them; the connecting piece 78 is disposed on the swing mixing plate 73 and is rotatably connected to the positioning rod 77 .

[0047] When the sliding block 76 is arranged on the oscillating mixing plate 73 and rotates along the first limiting groove 74 and the second limiting groove 75, the oscillating mixing plate 73 can rotate and swing along the positioning rod 77 arranged on the sliding sleeve 71 through the connecting piece 78, so that the oscillating mixing plate 73 can swing obliquely, thereby increasing the mixing effect of the oscillating mixing plate 73 on the sodium hydroxide and ethanol in the stirring tank 2.

[0048] See also Figure 8 As shown, the sodium hydroxide ethanol solution mixing equipment for processing carboxymethyl cellulose also includes an anti-precipitation mechanism 8 arranged in the stirring tank 2 and used to prevent material precipitation; the anti-precipitation mechanism 8 includes a rotating intermittent rotating disk 81, a contact block 82 and a scraper plate 83; the rotating intermittent rotating disk 81 is arranged on the stirring rod and is coaxially fixed to the stirring rod; the contact block 82 is arranged on the rotating intermittent transmission disk, and the contact block 82 is cylindrical; the scraper plate 83 is rotatably arranged in the stirring tank 2, and the contact block 82 is a flexible deformable material. When the contact block 82 contacts the rotating intermittent block 84, the rotating intermittent block 84 can be driven to rotate and then continue to rotate. After the contact, the contact block 82 is subjected to the flow resistance of sodium hydroxide and ethanol in the rotating intermittent block 84 in the stirring tank, causing the contact block 82 to produce an inclined deformation, and then lose contact with the rotating intermittent block 84, thereby achieving an intermittent contact rotation effect on the rotating intermittent block 84.

[0049] In order to prevent sodium hydroxide and ethanol from precipitating at the bottom of the stirring tank 2, when the stirring rod rotates, it can drive the rotating intermittent rotating disk 81 coaxially fixed therewith to rotate. When the rotating intermittent rotating disk 81 rotates, it can drive the contact block 82 and the scraper plate 83 to evenly scrape the bottom of the stirring tank 2, effectively preventing sodium hydroxide and ethanol from precipitating at the bottom of the stirring tank 2.

[0050] See also Figure 8 As shown, the anti-sedimentation mechanism 8 also includes a rotating intermittent block 84; the rotating intermittent block 84 is disposed in the stirring tank 2, and the rotating intermittent block 84 is used to contact with the contact block 82 and rotate, and the rotating intermittent block 84 is triangular in shape.

[0051] When the rotating intermittent rotating disk 81 rotates, it can drive the rotating intermittent block 84 fixedly connected thereto to rotate. When the rotating intermittent block 84 rotates, it can intermittently contact the contact block 82 and the scraper plate 83, which can prevent the scraper plate 83 from always rotating and contacting the bottom of the stirring tank 2 and causing damage to the bottom of the stirring tank 2, and can also prevent the precipitation of sodium hydroxide and ethanol during stirring.

[0052] See also Figure 8 As shown, the anti-sedimentation mechanism 8 further includes a rotating sleeve 85 ; the rotating sleeve 85 is rotatably disposed on the stirring tank 2 , and the rotating sleeve 85 is fixedly connected to the rotating intermittent block 84 and the scraper plate 83 .

[0053] The rotating sleeve 85 is arranged inside the stirring tank 2 through a bearing. The rotating sleeve 85 is fixedly connected to the contact block 82 and the scraper plate 83 respectively. When the contact block 82 and the scraper plate 83 rotate, the rotating sleeve 85 can be driven to perform synchronous rotational motion.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
