Description

Technical Field

[0001] The utility model relates to a stirring device for a coagulant, in particular to a stirring device for stirring a mixed material composed of a coagulant and a solvent, such as in latex production, to rapidly dissolve the coagulant. Background Art

[0002] Latex coagulation is one of the important processes in latex production. The principle is that a small amount of coagulant is added to the latex and stirred to neutralize the charges of the coagulant particles and the latex particles, prompting the latex particles to irreversibly connect and aggregate with each other to form a solid latex material with excellent physical properties.

[0003] The coagulant, also known as a strong aggregating agent or an immediate-effect aggregating agent, is mainly electrolytes such as acids and salts commonly used in the latex industry. The coagulant needs to be modulated before use, that is, a stirring device is used to mix and stir the coagulant with a solution to melt the coagulant in the solution.

[0004] Existing stirring devices for coagulants, such as the coagulant stirring tank for a nitrile glove production line disclosed in the utility model patent with the patent number 202121159017.3, are provided with a feed inlet on the upper cover of the tank body, a discharge outlet at the bottom of the tank body, a vertical rotating shaft is arranged in the middle of the tank body, and a plurality of horizontal cylindrical stirring rods are fixedly arranged at intervals beside the rotating rod, and the upper end of the rotating shaft is connected with a motor. Therefore, during use, the mixed material composed of the coagulant and the solvent enters the interior of the tank body from the feed inlet, and the motor drives the rotating shaft and the stirring rods to rotate to stir the coagulant and the solvent, helping the coagulant to decompose into a solution in the solvent, and the solution at the bottom of the tank body is discharged from the discharge outlet.

[0005] However, since the contact area between the horizontal cylindrical stirring rods and the coagulant and the solution is small, part of the coagulant flows out of the discharge outlet with the flowing solution before contacting the stirring rods, resulting in insufficient decomposition and uneven distribution of the coagulant in the obtained solution. If this solution is used in latex coagulation production, it will lead to poor quality of the latex products. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the problem that in the existing stirring device for coagulants, the contact area between the stirring rods and the coagulant and the solution is small, resulting in part of the coagulant flowing out of the discharge outlet with the flowing solution before contacting the stirring rods, and the coagulant in the solution is insufficiently decomposed and unevenly distributed.

[0007] To achieve the above purpose, the utility model provides a stirring device for a coagulant, including: a tank body 1, a tank cover 2, a stirring mechanism 4, and a motor 3.

[0008] The top of the tank body 1 is open and the bottom is closed, and a discharge outlet 14 is arranged at the lower part.

[0009] The can lid 2 is in a shape matching the top of the can body 1. The can lid 2 is provided with a feed inlet 21 and is closed on the top of the can body 1.

[0010] The stirring mechanism 4 is arranged inside the can body 1 and includes a rotating shaft 41. The first center line L1 of the rotating shaft 41 coincides with the second center line L2 of the can body 1.

[0011] A plurality of transverse stirring rods 42 are fixedly arranged on the side of the rotating shaft 41.

[0012] The motor 3 is fixedly arranged on the upper side of the middle part of the can lid 2. The rotating end 31 of the motor 3 passes through the can lid 2 and is fixedly connected to the upper end of the rotating shaft 41.

[0013] The stirring rod 42 is provided with a plurality of transverse through holes 43, and each through hole 43 is arranged along the fourth center line L4 of the stirring rod 42.

[0014] Therefore, during use, the mixed material composed of the coagulant and the solvent enters the inner tank 11 of the can body 1 from the feed inlet 21. The motor 3 drives the rotating shaft 41 to drive the stirring rod 44 to rotate, so as to stir the coagulant and the solvent.

[0015] During the stirring process, when the stirring rod 42 rotates with the rotating shaft 41 to stir the solution, part of the solution will pass through each through hole 43, increasing the degree of disturbance of the solution and achieving a better stirring effect.

[0016] Preferably, the plurality of stirring rods 42 are divided into multiple groups, and the number of stirring rods 42 in each group is the same and is evenly arranged along the first center line L1 of the rotating shaft 41.

[0017] At least one group of stirring rods 42 is provided with a vertical scraping plate 44 on the side far from the rotating shaft 41. When the rotating shaft 41 rotates, the scraping plate 44 moves along the surface of the inner side wall of the can body 1.

[0018] By using the scraping plate 44, the solution close to the side wall of the inner tank 11 can be scraped off, preventing the solution from sticking to the inner wall and improving the stirring effect.

[0019] Preferably, at least two groups of stirring rods 42 are provided with vertical scraping plates 44 on the side far from the rotating shaft 41. The upper end and / or the lower end of the scraping plate 44 is fixedly connected with an annular support frame 46, and the center of the annular support frame coincides with the first center line L1 of the rotating shaft 41. By using the annular support frame 46 to reinforce the scraping plate 44, it can prevent the scraping plate 44 from tilting due to force and resulting in a poor scraping effect on the wall.

[0020] Preferably, the can body 1 includes an inner tank 11. The inner tank 11 is a cylindrical shape with an open top and a closed bottom. A cylindrical outer shell 12 is arranged outside the inner tank 11. The outer shell 12 wraps the inner tank 11, and a heating element 5 is arranged between the inner tank 11 and the outer shell 12 for heating the solution.

[0021] Preferably, an annular heat conducting pad 52 is sleeved outside the inner tank 11, and the heating elements 5 are uniformly fixed outside the annular heat conducting pad 52, which plays a role in heat conduction and heat transfer, facilitating uniform heating and preventing local overheating.

[0022] Preferably, the tank lid 2 is detachably installed at the top end of the tank body 1, and the staff can separate the tank lid 2 from the tank body 1 to inspect, wash and repair the inside of the tank body 1.

[0023] Preferably, at least two telescopic rods 22 are arranged outside the tank body 1. The lower ends of the telescopic rods 22 are fixedly connected to the outer side wall of the outer shell 12 through lower fixing blocks 17, and the upper ends of the telescopic rods 22 are fixedly connected to the outer side wall of the tank lid 2 through upper fixing blocks 23.

[0024] The telescopic rod 22 has two states of elongation and shortening. When in the extended state, it can provide support for the tank lid 2 to separate it from the tank body 1. When in the shortened state, the tank lid 2 covers the tank body 1 to close the top end of the tank body 1.

[0025] In summary, the utility model uses the stirring rod with through holes 43 for stirring, and the stirring effect is good. It can effectively solve the problems in the existing stirring device for coagulants, where the contact area between the stirring rod and the coagulant and the solution is small, resulting in some coagulants flowing out of the discharge port with the flowing solution before contacting the stirring rod, and the decomposition of the coagulant in the solution is insufficient and unevenly distributed.

[0031] The embodiments of the present utility model will be described in detail below with reference to the drawings. The following description is a specific implementation of the claims of the present utility model.

[0032] Embodiment

[0033] Figure 1 Shows the structure of the stirring device for the coagulant when the tank lid is closed; Figure 2 Shows the structure of the stirring device for the coagulant when the tank lid is open; Figure 3 Is along Figure 1 The sectional view of the tank body cut along A-A in shows the internal structure of the stirring device for the coagulant.

[0034] As Figure 1 、 2 Shown, the stirring device for the coagulant includes a tank body 1, a tank lid 2, a motor 3, a stirring mechanism 4, and a heating element 5.

[0035] Combined with Figures 1 - 3 Looking at it, the tank body 1 includes an inner tank 11, and the inner tank 11 is a cylindrical shape with an open top and a closed bottom. A discharge port 14 is provided at the lower part of the inner tank 11 and is connected to a discharge pipeline 140 for discharging materials.

[0036] Outside the inner tank 11, a cylindrical outer shell 12 is provided, and the outer shell 12 wraps the inner tank 11. Support legs 17 are provided at the bottom of the outer shell 12 for lifting the tank body 1 to provide space for the discharge pipe 140.

[0037] A heating element 5 is provided between the inner tank 11 and the outer shell 12, including an electric heating element 51. An annular heat conducting pad 52 is sleeved outside the inner tank 11, and the electric heating element 51 is uniformly fixed on the outside of the annular heat conducting pad 52, playing a role of heat conduction and heat transfer, facilitating uniform heating and preventing local overheating.

[0038] Combined with Figures 1 - 3 Looking at it, the tank lid 2 is a circle matching the top of the tank body 1, covering the top of the tank body 1. A circular hole 24 is provided in the middle of the tank lid 2, and a feed port 21 is provided beside the circular hole 24. A feed hopper 210 is also installed above the feed port 21 for feeding. The meaning of the above "matching" is that the diameter of the tank lid 2 is greater than or equal to that of the tank body 1, capable of covering the tank body 1, and the lower side of the tank lid 2 protrudes to form a frustum with a diameter equal to the inner diameter of the inner tank 11, which can just be clamped on the top of the inner tank 11 without shaking.

[0039] As Figure 2 Shown, the tank lid 2 can be detachably installed at the top of the tank body 1. Two telescopic rods 22 are provided on the outside of the tank body 1. The lower end of each telescopic rod 22 is fixedly connected to the outer side wall of the outer shell 12 through a lower fixing block 17, and the upper end of the telescopic rod 22 is fixedly connected to the outer side wall of the tank lid 2 through an upper fixing block 23.

[0040] The telescopic rod 22 is a pneumatic or electric telescopic element, which has two states: elongation and shortening. When in the elongation state, it can support the can lid 2 to separate it from the can body 1. When in the shortening state, the can lid 2 covers the can body 1 to seal the top of the can body 1.

[0041] See Figure 3 , the stirring mechanism 4 is arranged inside the can body 1 and includes a rotating shaft 41. The first center line L1 of the rotating shaft 41 coincides with the second center line L2 of the can body 1, that is, the rotating shaft 41 is located at the middle position inside the can body 1.

[0042] See Figure 2 、 Figure 3 , the motor 3 is fixedly arranged on the upper side of the middle part of the can lid 2. The rotating end 31 of the motor 3 passes through the circular hole 24 and is fixedly connected to the upper end of the rotating shaft 41 to drive the rotating shaft 41 to rotate.

[0043] Figure 4 Shows the structure of the stirring mechanism. Figure 5 Is along Figure 4 The sectional view of the stirring mechanism cut along B-B in

[0044] As Figure 4 Shown, 20 horizontal stirring rods 42 are fixedly arranged on the side of the rotating shaft 41. Every 5 stirring rods 42 are divided into a group, and there are a total of four groups. The number of stirring rods 42 in each group is the same (5) and they are vertically and evenly arranged along the first center line L1 of the rotating shaft 41. Figure 3 、 4 In

[0045] On the side of two groups of stirring rods 42a, 42c away from the rotating shaft 41, vertical scraping plates 44 are respectively arranged, so that when the rotating shaft 41 rotates, the scraping plates 44 move along the surface of the inner side wall of the can body 1. Figure 4 The enlarged view in

[0046] Combined with Figure 5 It can be seen that the small arrow b indicates the rotation direction of the rotating shaft 41. The side of the scraping plate 44 facing the side wall of the inner tank 11 is an arc surface, and an α bevel angle is formed on the side facing its moving direction.

[0047] The lower end of the scraping plate 44 is fixedly connected with an annular support frame 46. The center of the annular support frame coincides with the first center line L1 of the rotating shaft 41, which is used to reinforce the scraping plate 44 to prevent it from tilting under force and resulting in a poor wall scraping effect.

[0048] Combined withFigures 3 - 5 As can be seen, each stirring rod 42 is provided with a plurality of through holes 43.

[0049] See Figure 5 , each of the through holes 43 is arranged horizontally along the fourth center line L4 of the stirring rod 42, and the third center line L3 of each through hole 43 is perpendicular to the first center line L1 (pointing into the paper) of the rotating shaft 41.

[0050] Therefore, during use, the mixed material composed of the coagulant and the solvent enters the interior of the inner tank 11 of the tank body 1 from the feed port 21, and the motor 3 drives the rotating shaft 41 to drive the stirring rod 44 to rotate, so as to stir the coagulant and the solvent.

[0051] During the stirring process, when the stirring rod 42 rotates with the rotating shaft 41 and stirs the solution, part of the solution will pass through each through hole 43, increasing the degree of disturbance of the solution and achieving a better stirring effect.

[0052] See Figure 5 , the included angle β between the third center line L3 of each through hole 43 and the fourth center line L4 of the stirring rod 42 should be equal to 90°, so that during the process of the stirring rod 42 rotating with the rotating shaft 41 and stirring the solution, the fluid can smoothly pass through the stirring rod 42, or less than 90°, so that the hole wall of the through hole 43 can generate an outward pushing force on the solution, which can improve the stirring effect.

[0053] At the same time, since a scraper 44 with an α bevel angle is provided at the end of the stirring rod 42, when the rotating shaft 41 rotates, the solution close to the side wall of the inner tank 11 can be scraped off and pushed inward, preventing the solution from sticking to the inner wall and improving the stirring effect.

[0054] The utility model can effectively solve the problems that in the existing stirring device for coagulants, the contact area between the stirring rod and the coagulant and the solution is small, resulting in part of the coagulant flowing out of the discharge port with the flowing solution before contacting the stirring rod, and the coagulant in the solution is not decomposed sufficiently and is unevenly distributed.
