Description

Technical Field

[0001] This utility model belongs to the field of chemical batching reactor technology, specifically relating to a safe chemical batching reactor. Background Technology

[0002] A safety-type chemical batching reactor is a mixing and reaction device specifically designed for chemical production. Its core function is to improve the safety, uniformity, and efficiency of the reaction process by optimizing the structural design and control system.

[0003] Chinese patent document CN221386090U discloses a safe chemical batching reactor. Through the design of structures such as a feed cylinder, a guide cavity, a connecting shaft, and guide plates, the raw materials introduced by the feed pipe can enter the reactor body intermittently for mixing and reaction by means of the force of the rotating rod in the stirring mechanism. This effectively controls the feed rate of the raw materials and achieves uniformity in the mixing and reaction process.

[0004] However, in the existing technology, although the mixing tank can improve the mixing uniformity through the synergy of stirring and feeding, the raw materials can only be added dropwise to a fixed area in the tank, which is still prone to local accumulation of raw materials and delayed dispersion. Therefore, a safe chemical mixing tank is proposed. Utility Model Content

[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0031] like Figures 1-4 As shown, a safe chemical batching vessel includes a batching vessel body 1 that can accommodate raw materials for mixing and reaction. A circulation component 2 is provided on one side of the batching vessel body 1 to allow the raw materials to flow along a fixed path within the batching vessel. A rotating component 3 is provided on the batching vessel body 1 to improve the mixing degree of each component of the raw materials. A feeding component 4 is also provided on the batching vessel body 1 to ensure the effective dispersion and full mixing of the raw materials.

[0032] In this embodiment: the batching vessel body 1 includes a vessel body 101, a vessel cover 102 is fixedly connected above the vessel body 101, a discharge pipe 103 is fixedly connected below the vessel body 101, and a discharge valve 104 is fixedly connected below the discharge pipe 103.

[0033] The vessel body 101 serves as the main container of this batching vessel, providing an environment for the mixing and reaction of raw materials. The vessel cover 102 seals the opening above the vessel body 101 and provides installation positions for components such as the frame 301 and the bearing 304. The raw materials inside the vessel body 101 are discharged outward through the discharge pipe 103, allowing the raw materials to flow out of this batching vessel through the opened discharge valve 104, or enter the circulation component 2 when the discharge valve 104 is closed.

[0034] In this embodiment: the circulation component 2 includes a bracket 201 fixedly installed on one side of the vessel body 101, a pump 202 fixedly installed on the bracket 201, an outlet pipe 203 is provided between the discharge pipe 103 and the feed end of the pump 202, and an injection pipe 204 is provided between the discharge end of the pump 202 and the liquid inlet nozzle 404.

[0035] The bracket 201 provides an installation position for the pump 202. When the pump 202 is running, it can continuously draw out the raw material flowing into the discharge pipe 103 through the outlet pipe 203, and then inject it into the liquid inlet nozzle 404 along the injection pipe 204.

[0036] In this embodiment: the rotating component 3 includes a frame 301 fixedly installed on the vessel cover 102, a motor 302 fixedly installed inside the frame 301, a drive gear 303 fixedly connected to the output end of the motor 302, a bearing 304 fixedly installed on the vessel cover 102 on one side of the motor 302, a hollow shaft 305 coaxial with and passing through the bearing 304 is movably connected inside the bearing 304, and a driven gear 306 of the same height as the drive gear 303 is fixedly connected to the outer side of the hollow shaft 305;

[0037] The drive gear 303 is meshed with the driven gear 306, and the bearing 304 is rotatably connected to the hollow shaft 305.

[0038] The motor 302, which is mounted on the lid 102 via the frame 301, can drive the hollow shaft 305, which is mounted on the center of the lid 102 via the drive gear 303 and the driven gear 306, to rotate during operation. The hollow shaft 305, after rotating, can drive the ball-head rod 411, which passes through it and is fixedly connected to its inner side, to rotate together.

[0039] In this embodiment: the injection component 4 includes an injection component that allows the raw materials to be conveniently injected into the batching vessel, a guide component that can continuously disperse and mix the raw materials, and a stirring component that can spray the raw materials injected into it from multiple directions;

[0040] The feed guide includes a first valve pipe 401 fixedly connected to the vessel cover 102, a three-way pipe 402 fixedly connected above the first valve pipe 401, a venturi pipe 403 fixedly connected above the three-way pipe 402, a liquid inlet nozzle 404 fixedly connected to the feed end of the venturi pipe 403, a second valve pipe 405 fixedly connected to one side of the three-way pipe 402, a feed pipe 406 fixedly connected to one side of the second valve pipe 405, and a rotary joint 407 fixedly connected to the lower end of the feed pipe 406. The stirring component includes a component fixedly connected below the rotary joint 407 and along the hollow... The axis of shaft 305 passes through the ball-head rod 411. The feeding component includes a feed pipe 408 fixedly connected to the suction end of the venturi tube 403. A third valve pipe 409 is fixedly connected to the end of the feed pipe 408 away from the venturi tube 403. A hopper 410 is fixedly connected above the third valve pipe 409. The mixing component also includes multiple mixing rods 412 fixedly connected to the outer side of the lower end of the ball-head rod 411. A check nozzle 413 is fixedly connected to the lower end of the ball-head rod 411 and the ends of the multiple mixing rods 412 away from the ball-head rod 411.

[0041] Both the ball-head rod 411 and the stirring rod 412 are hollow, and the center line of the ball-head rod 411 does not coincide with the center line of the stirring rod 412.

[0042] The first valve 401 controls the opening and closing of the first feed channel between the vessel lid 102 and the three-way pipe 402; the second valve 405 controls the opening and closing of the second feed channel between the injection pipe 406 and the three-way pipe 402; and the third valve 409 controls the opening and closing of the raw material conveying channel between the feed pipe 408 and the hopper 410. The raw material injected into the circulation component 2 through the liquid inlet nozzle 404 is atomized into fine droplets or a gas-liquid mixture when it enters the venturi tube 403. The venturi tube 403, which forms a negative pressure at its throat, propels the raw material in the hopper 410 along the feed pipe 408. The material is drawn in through the third valve pipe 409 after it is opened. The material in the stationary injection pipe 406 is transported to the ball-head rod 411 that can rotate with the hollow shaft 305 through the rotary joint 407. The material in the ball-head rod 411 can flow in multiple directions through the stirring rod 412 which is at a certain angle to the main body of the ball-head rod 411. All the material entering the ball-head rod 411 can be sprayed out through the check nozzle 413 connected to it. The other part will be sprayed out through the check nozzle 413 connected to the stirring rod 412 after entering each stirring rod 412.

[0043] Working principle: When this batching vessel is installed and put into use, after the first valve pipe 401 and the third valve pipe 409 are opened, the raw materials to be mixed are continuously fed into the hopper 410, so that the raw materials can flow naturally into the venturi pipe 403 through the third valve pipe 409 and the feed pipe 408, and then flow naturally into the vessel body 101 through the venturi pipe 403, the three-way pipe 402 and the first valve pipe 401. After there is a certain volume of raw materials in the vessel body 101, the pump 202 and the motor 302 can be started.

[0044] After the pump 202 is running, it can extract the raw material in the vessel 101 and inject it into the liquid inlet nozzle 404 connected to the feed end of the venturi tube 403. When the liquid inlet nozzle 404 can continuously spray raw material droplets, the venturi tube 403, which can form a negative pressure at the throat, will continuously extract the raw material in the hopper 410 through the feed pipe 408 and the third valve pipe 409.

[0045] The raw materials entering the Venturi tube 403 through different channels will be continuously mixed in the Venturi tube 403, and then after entering the three-way tube 402, they will enter the reactor body 101 through the opened first valve tube 401, or when the first valve tube 401 is closed and the second valve tube 405 is open, they will enter the ball head rod 411 that is continuously rotating due to the operation of the motor 302 through the second valve tube 405, the injection tube 406, and the rotary joint 407.

[0046] Since the raw materials enter the vessel body 101 through the various check nozzles 413 facing different directions after entering the ball head rod 411, and the stirring rod 412 will continuously rotate with the ball head rod 411 to stir the raw materials in the vessel body 101, the components of the raw materials will be fully mixed in the process of continuous flow and dispersion.

[0047] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
