Description

Technical Field

[0001] The utility model relates to the technical field of stirring paddles for reaction kettles, in particular to a stirring paddle for reaction kettles. Background Art

[0002] The broad understanding of the reactor is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be achieved;

[0003] Among them, the "high-efficiency reactor stirring paddle" disclosed by the authorization number "CN220091136U" has a specific technical structure setting, which allows the materials in the reactor to be fully stirred, so that the materials, whether powder or liquid, can be fully mixed, achieving a higher working efficiency. At the same time, the powder will not float and not participate in the stirring, which greatly reduces the material loss rate;

[0004] Although the stirring paddle of the reactor improves the efficiency of stirring the reaction raw materials and does not cause powder to float and not participate in stirring, when stirring in most reactors at present, the driving shaft drives the stirring paddle to rotate in one direction for stirring. The centrifugal force in a single direction generates, and it takes a long time to mix the reaction raw materials. In addition, the liquid raw materials on the outside of the centrifugal force lack the diversion effect, resulting in a decrease in the raw material mixing efficiency of the reactor, thereby reducing production.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a stirring paddle for a reactor, which is driven by a driving shaft to rotate the stirring paddle clockwise, and the mutual engagement of the first gear and the second gear causes the rotating rod to drive the planetary gear to rotate counterclockwise. At this time, the engagement relationship between the planetary gear and the gear ring drives the stirring frame to rotate counterclockwise through the turntable, thereby generating two centrifugal forces in opposite directions, so that the raw materials inside the reactor body are stirred and mixed in different directions. At this time, the raw materials pass through the connecting rods, and the guide plate rotates to make the guide holes guide the liquid raw materials, so that the raw materials can be mixed more fully, thereby shortening the stirring time and improving the mixing efficiency and production volume.

[0014] Compared with the prior art, the utility model provides a stirring paddle for a reactor, which has the following beneficial effects:

[0015] 1. The utility model drives the stirring paddle to rotate clockwise through the driving shaft, and the first gear and the second gear are meshed with each other to make the rotating rod drive the planetary gear to rotate counterclockwise.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a stirring paddle for a reactor.

[0025] See also Figure 1 - Figure 5A stirring paddle for a reactor comprises a reactor body 1, a fixed disc 2 and a connecting rod 3 movably mounted on the top of the inner wall of the reactor body 1, a driving shaft 101 is rotatably mounted on the top of the reactor body 1 through a bearing, a rotating disc 201 is rotatably mounted on the outer side of the fixed disc 2, a first gear 202 is fixedly mounted on the outer side of the driving shaft 101 inside the rotating disc 201, a rotating rod 203 is rotatably mounted on one side of the bottom of the fixed disc 2, and a rotating rod 203 is fixedly mounted on the outer side of the rotating rod 203 to interact with the first gear 202 The second gear 204 is meshed with the planetary gear 205, and the bottom of the rotating rod 203 is fixedly installed with a planetary gear 205, the inner wall of the turntable 201 is fixedly connected with a gear ring 206 that meshes with the planetary gear 205, the bottom of the turntable 201 is fixedly installed with a stirring frame 207, the connecting rod 3 is fixedly installed on both sides of the stirring frame 207, and the outer side of the driving shaft 101 is evenly fixed with stirring paddles 208, and a guide plate 301 is rotatably installed between each group of stirring frames 207, and the guide plate 301 is evenly opened with guide holes 302 inside.

[0026] Specifically, the first gear 202 rotates clockwise to drive the second gear 204 to rotate, so that the rotating rod 203 drives the planetary gear 205 to rotate counterclockwise. At this time, the planetary gear 205 rotates on the inner side of the gear ring 206 to drive the turntable 201 to rotate, so that the turntable 201 drives the stirring frame 207 to rotate counterclockwise, and the driving shaft 101 drives the stirring paddle 208 to rotate clockwise to stir the raw materials. At this time, two centrifugal forces in opposite directions are generated, and then the raw materials pass through the connecting rods 3. Due to the centrifugal force, the liquid raw materials have different flow rates, so that the guide plate 301 rotates when the raw materials pass through the guide plate 301, and the raw materials are diverted through the guide hole 302, so that the raw materials inside the reactor body 1 are stirred and mixed in different directions, so that they are mixed more evenly, thereby improving the mixing efficiency and production volume.

[0027] Furthermore, a shaft sealing shell 102 is fixedly installed on the top of the reactor body 1, a reducer 103 is fixedly connected to the top of the shaft sealing shell 102, a driving motor 104 is fixedly installed on the top of the reducer 103, the top end of the driving shaft 101 passes through the shaft sealing shell 102 and is fixedly connected to the output end of the reducer 103, and the input end of the reducer 103 is fixedly connected to the output end of the driving motor 104;

[0028] Furthermore, a feed inlet 105 is fixedly installed through one side of the top of the reactor body 1, and a sealing cover 106 is rotatably installed on the top of the feed inlet 105;

[0029] Specifically, the power output of the driving motor 104 is adjusted by the speed reduction of the reducer 103 to make the rotation speed more stable, thereby driving the driving shaft 101 to rotate stably. The driving shaft 101 is sealed and protected by the shaft sealing shell 102 to avoid the influence of external factors when the driving shaft 101 rotates. The chemical raw materials to be stirred are conveniently added to the interior of the reactor body 1 through the feed port 105, and then sealed by the sealing cover 106 to avoid leakage during the reaction process.

[0030] Furthermore, a reinforcement steel ring 107 is evenly and fixedly installed on the outer wall of the reactor body 1, and a discharge port 108 is fixedly connected to the bottom of the other side of the reactor body 1;

[0031] Furthermore, a support seat 4 is evenly fixedly installed on the outer wall of the reactor body 1, and a hanging hole 401 is opened through the interior of the support seat 4;

[0032] Specifically, the reinforcement steel ring 107 is fixed to the outer surface of the reactor body 1 to make the reactor body 1 stronger, so as to prevent the surface of the reactor body 1 from being deformed after being hit and reducing the service life of the reactor body 1. The stirred material can be discharged through the discharge port 108. The reactor body 1 can be supported by the support seat 4 to prevent the reactor body 1 from rolling horizontally when it is installed horizontally. The hanging hole 401 facilitates the use of a rope to pull up the reactor body 1 after installation, which is convenient for the staff to operate.

[0033] Furthermore, a pressure monitoring gauge 5 is fixedly installed on the other side of the top of the reactor body 1, and a pressure discharge port 6 is fixedly connected through the other side of the top of the reactor body 1;

[0034] Specifically, the air pressure inside the reactor body 1 is monitored by the pressure monitoring meter 5. When the pressure inside the reactor body 1 is too high, the pressure inside the reactor body 1 is discharged through the pressure relief port 6 to avoid a potential danger caused by excessive pressure due to the reaction of raw materials inside the reactor body 1.

[0035] Working principle: First, the staff adds the chemical raw materials into the interior of the reactor body 1 through the feed port 105, and then seals the feed port 105 through the sealing cover 106. Then, the output end of the driving motor 104 rotates to transmit the power to the reducer 103. After the reducer 103 is decelerated and adjusted to a stable speed, it drives the driving shaft 101 to rotate, thereby driving the stirring paddle 208 to rotate clockwise. At this time, the driving shaft 101 drives the first gear 202 to rotate clockwise, and the first gear 202 is engaged with the second gear 204 so that the first gear 202 drives the second gear 204 to rotate counterclockwise. Then, the rotating rod 203 is driven by the planetary gear 20 5 drives the gear ring 206 to rotate, so that the gear ring 206 drives the stirring frame 207 counterclockwise through the turntable 201. At this time, two centrifugal forces in opposite directions are generated inside the reactor body 1 to stir and mix the chemical raw materials. Due to the centrifugal force, the liquid raw materials have different flow rates, so that the guide plate 301 rotates when the raw materials pass through the guide plate 301, and the raw materials are guided through the guide holes 302, so that the chemical raw materials are mixed more evenly. When the pressure monitoring meter 5 detects that the air pressure inside the reactor body 1 is too high, the pressure inside the reactor body 1 can be discharged through the pressure discharge port 6, and then the material can be discharged through the discharge port 108 after the stirring is completed.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
