[0002] A reaction kettle is a device used for carrying out chemical reactions, physical reactions or biological reactions. It usually consists of a sealed container and related control systems, and is used to carry out various chemical or biological processes under controlled conditions. Reaction kettles are widely used in the fields of chemical product production, pharmaceuticals, food, beverages, pigments, coatings, etc. According to different reaction requirements, reaction kettles can be of different types such as glass reaction kettles, stainless steel reaction kettles, and kettle-type reaction kettles, and their designs and uses are different. However, when certain reaction properties are special or reaction conditions are harsh, difficulties may be encountered during feeding, which affects the progress of the reaction.

However, general reaction kettles hardly consider the problem of sealing during feeding, and harmful gas leakage or material volatilization may occur during feeding. At the same time, when solid materials are put in, the materials may accumulate and are unevenly distributed, thus affecting the reaction efficiency and being unfavorable for the interaction between reactants.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.

[0030] Refer to Figures 1-5, an embodiment provided by the present utility model: a feeding device for a reaction kettle, including a liquid feed pipe 8, the bottom of the left end of the liquid feed pipe 8 is fixedly connected to the outer wall of the right end of the reaction kettle body 1, the upper part of the inner wall of the liquid feed pipe 8 is slidably connected with a floating leak plate 12, the upper part of the inner wall of the liquid feed pipe 8 is fixedly connected with a fixed leak plate 13, water inlets 20 are opened on the opposite sides of the outer walls of the floating leak plate 12 and the fixed leak plate 13, the bottom outer wall of the fixed leak plate 13 is fixedly connected with a first conical plate 14, the side wall of the first conical plate 14 is fixedly connected to the inner wall of the liquid feed pipe 8, the bottom of the inner wall of the liquid feed pipe 8 is fixedly connected with a second conical plate 17, the top of the bottom opening of the first conical plate 14 is slidably connected with a conical piston 16, the bottom of the bottom opening of the second conical plate 17 is slidably connected with a conical piston 16, the opposite sides of the conical piston 16 are fixedly connected to both ends of a connecting rod 15, the bottom of the inner wall of the liquid feed pipe 8 is fixedly connected with a support structure 19, a cylinder 21 is installed on the top wall of the support structure 19, the output end of the cylinder 21 is fixedly connected to the bottom outer wall of the conical piston 16, a valve 11 is installed on the top outer wall of the liquid feed pipe 8, the top outer wall of the valve 11 is fixedly connected with a liquid inlet 10, the bottom outer wall of the conical piston 16 is fixedly connected with a water blocking cover 18, the cylinder 21 is arranged inside the water blocking cover 18, the top outer wall of the reaction kettle body 1 is fixedly connected with a reaction kettle cover 2, a motor 7 is installed in the middle of the top wall of the reaction kettle cover 2, the output end of the motor 7 passes through the top outer wall of the reaction kettle cover 2 and is fixedly connected with a stirring rod 9, a solid inlet 3 is opened on the left side of the top wall of the reaction kettle cover 2, and a sealing cover 4 is threadedly connected to the top outer wall of the solid inlet 3.

[0031] Specifically, two inlets are designed to achieve the solid-liquid separation effect, and a sealing cover 4 is also provided at the top of the solid inlet 3. Open the valve 11 and pour the liquid reactant from the liquid inlet 10 into the liquid feed pipe 8. The floating leak plate 12 will slowly float up. The liquid reactant flows through the water inlet 20 on it and into the first conical plate 14 through the water inlet 20 on the fixed leak plate 13. Then the cylinder 21 pushes the conical piston 16 and the connecting rod 15 upward until the lower conical piston 16 abuts against the bottom opening of the second conical plate 17, and the liquid flows into the second conical plate 17 and accumulates. Then the cylinder 21 contracts until the upper conical piston 16 blocks the bottom opening of the first conical plate 14. At this time, the liquid reactant can smoothly enter the reaction kettle. The whole process includes three sealing devices: the valve 11, the floating leak plate 12 and the conical piston 16, ensuring that there will be no leakage of harmful gases in the reaction kettle and no volatilization of materials.

[0032] Specifically, the water blocking cover 18 is used to prevent the liquid reactant from interfering with the normal operation of the cylinder 21 and wraps the cylinder 21 inside to protect the cylinder 21.

[0033] Specifically, a sealing structure is also provided at the connection between the output end of the motor 7 and the reaction kettle cover 2.

[0034] The top outer wall of the fixed orifice plate 13 is the lowest position where the floating orifice plate 12 slides on the inner wall of the liquid feed pipe 8.

[0035] Specifically, when the liquid reactant enters the liquid feed pipe 8, the floating orifice plate 12 will float up. When the feeding is completed and the liquid reactant completely enters the interior of the liquid feed pipe 8, the floating orifice plate 12 will gradually descend until it coincides with the top outer wall of the fixed orifice plate 13.

[0036] A weighing device 6 is provided on the rear outer wall of the reactor cover 2, and trays 5 are fixedly connected to both ends of the top wall of the weighing device 6.

[0037] Specifically, the weighing device 6 can monitor the weight of the feed in real time to ensure that the feeding amount meets the requirements and avoid overfeeding or underfeeding.

[0038] Working principle: First, solid reactants are added through the solid feed inlet 3, and at the same time, the motor 7 starts to work. The stirring rod 9 is used to prevent material accumulation. After the feeding is completed, the sealing cover 4 is covered to maintain the sealed environment inside the reactor. Then, the valve 11 is opened to pour the liquid reactant from the liquid feed inlet 10 into the liquid feed pipe 8. The floating orifice plate 12 will slowly start to float under the buoyancy of the liquid reactant. The liquid reactant flows through the water inlet 20 on it and enters the first conical plate 14 through the water inlet 20 on the fixed orifice plate 13. When the feeding is completed and the liquid reactant completely enters the interior of the liquid feed pipe 8, the floating orifice plate 12 will gradually descend until it coincides with the top outer wall of the fixed orifice plate 13 to achieve the second sealing effect. Then, inside the liquid feed pipe 8, the cylinder 21 pushes up the conical piston 16 and the connecting rod 15 until the lower conical piston 16 abuts against the bottom opening of the second conical plate 17, and the liquid flows into the second conical plate 17 and accumulates. Then, the cylinder 21 contracts until the upper conical piston 16 blocks the bottom opening of the first conical plate 14 to achieve the third sealing effect. At this time, the liquid reactant can smoothly enter the interior of the reactor.
