Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a crystallization reaction kettle for amino acid chelate salts. Background Art

[0002] A reaction kettle is a container used for carrying out chemical reactions, suitable for various different reaction conditions, and allowing various materials to carry out chemical reactions under high temperature and high pressure. At present, reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food, and are one of the basic production equipments of many enterprises.

[0003] Nowadays, traditional crystallization reaction kettles usually set a stirrer in the kettle body to stir and react the materials. At present, to ensure the stirring effect and reaction effect of the materials, the stirrer is usually set in the center of the kettle body. However, due to the large space in the kettle body, the stirrer cannot stir the materials at any position in the kettle body (especially the edge position), so it directly affects the reaction effect and efficiency of the materials.

[0004] Secondly, after adding crystal seeds into the kettle body, crystals are prone to burst and precipitate under the action of the stirrer or at low temperature, resulting in crystallization of the product in the kettle body and unable to discharge the liquid material. At present, the existing method is to heat the kettle body to control the crystallization rate so that the kettle body can easily discharge the liquid material. However, the existing structure of the reaction kettle is not easy to heat it.

[0005] In summary, the existing crystallization reaction kettle has the above-mentioned deficiencies, so improvements need to be made. Summary of the Utility Model

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0038] Embodiment 1

[0039] As Figure 1-2 shown, this embodiment discloses a crystallization reactor for amino acid chelate salts, including:

[0040] A kettle body 1 with a kettle cavity 10;

[0041] A feed inlet 2 and a discharge outlet 3 are provided on the kettle body 1 and communicate with the kettle cavity 10;

[0042] A stirring device 4 is arranged in the kettle cavity 10 and can be controlled to start by a transmission device 5.

[0043] In this embodiment, an air inlet device 6 is further included. The air inlet device 6 has at least one passage for gas to pass through, and at least an exhaust end connected to the passage is formed in the kettle cavity 10.

[0044] In this embodiment, the air inlet device 6 is an inlet pipe provided on the kettle body 1 and supplied with gas by a gas source, and a shunt hole 60 constituting the exhaust end is formed on the inlet pipe.

[0045] As Figure 2 shown, in this embodiment, the shunt holes 60 have several rows, and the shunt holes in each row are circumferentially spaced apart on the circumferential side wall of the inlet pipe, and the adjacent shunt holes 60 in each row are arranged in a staggered manner.

[0046] In this embodiment, one end of the inlet pipe penetrates into the kettle cavity 10 from the top of the kettle body 1.

[0047] In this embodiment, the gas source is a gas supply pump.

[0048] In this embodiment, the transmission device 5 is a motor.

[0049] In this embodiment, the stirring device 4 has a stirring shaft 41 and paddle blades 42.

[0050] In this embodiment, a control valve 30 is provided at the discharge outlet 3 to control the discharge of materials from the reactor.

[0051] Referring to Figure 1-2 , the principle of this embodiment is as follows:

[0052] 1. Stirring principle:

[0053] The material can be added into the kettle cavity through the feed inlet at the top of the kettle body, and the stirring device is driven to start by the transmission device 5 to stir the material in the kettle cavity. After stirring or the material reaction is completed, it is discharged through the discharge port at the bottom of the kettle body to complete the stirring work. At present, the stirring principle of the reaction kettle is an extremely mature existing technology, so it will not be described in detail in this embodiment.

[0054] 2. Air inlet principle:

[0055] When the material is being stirred in the kettle cavity, the air supply pump supplies air to the air inlet pipe, and the air is ejected through the shunt holes to stir the material in the kettle cavity, thereby assisting the material stirring and improving the reaction effect and efficiency of the material.

[0056] It is worth mentioning that: in this embodiment, there are several rows of shunt holes on the air inlet pipe (refer to Figure 2 ), and the adjacent shunt ports are arranged in a staggered manner, which can make the shunt holes more densely distributed on the air inlet pipe, thereby improving the auxiliary effect of the jet.

[0057] It should be noted that: the distribution form of the shunt holes in this embodiment refers to Figure 2 , and Figure 1 only represents the position of the air inlet pipe in the kettle body and the position of the shunt holes on the air inlet pipe.

[0058] Embodiment 2 is different from Embodiment 1 in that:

[0059] As Figure 3-4 shown, in this embodiment, the air inlet device 6 is fixedly arranged on the inner wall of the kettle cavity 10 through the baffle 7.

[0060] In this embodiment, the baffle 7 includes:

[0061] The plate body 7a, which is spaced on the inner wall of the kettle cavity 10;

[0062] The rotating shaft 7b, which is rotatably connected between the plate bodies 7a;

[0063] The motor driver 7c, which can drive the rotating shaft 7b to rotate clockwise or counterclockwise;

[0064] Among them, the air inlet device 6 is composed of an air inlet nozzle 6a arranged on the kettle body 1 and a pipe body 6c connected to the air inlet nozzle 6a through a hose 6b. The pipe body 6c is fixedly connected to the rotating shaft 7b. The rotating shaft (7b) is connected to the motor driver (7c) and is controlled by the motor driver (7c) to rotate. The motor driver (7c) is fixedly connected to the plate body (7a).

[0065] Refer to Figure 3-4 The principle of this embodiment is:

[0066] 1. Intake principle:

[0067] When the material is stirred in the kettle cavity 10, the air supply pump supplies air to the intake nozzle 6a, enters the pipe body 6c through the hose 6b, and finally discharges from the diversion holes provided on the pipe body.

[0068] 2. Driving principle:

[0069] The baffle 7 is composed of a plate body 7a and a rotating shaft 7b. The intake pipe is fixed to the rotating shaft. When the motor driver drives the rotating shaft to rotate, the pipe body will rotate with the rotating shaft as the reference, and the position of the diversion holes in the kettle cavity will be adjusted, so as to better stir the material in the kettle cavity, thereby improving the stirring effect.

[0070] More specifically: When the diversion holes on the pipe body jet air in this embodiment, the motor driver 7c starts, drives the rotating shaft 7b to rotate, and the pipe body 6c fixedly connected to the rotating shaft 7b is also driven to rotate with the rotating shaft as the reference, thereby changing the original jet air trajectory, expanding the contact area between the air source and the material, and making it better assist in stirring the material.

[0071] Embodiment 3, the difference from Embodiment 2 is:

[0072] As Figure 5 shown, in this embodiment,

[0073] In this embodiment, the stirring shaft 41 of the stirring device 4 is supported on the bottom of the kettle cavity 10 through a bracket 9, and a bearing 91 for the stirring shaft 41 of the stirring device 4 to rotate is provided on the bracket 9.

[0074] In this embodiment, an anti-corrosion layer 11 is provided on the inner wall of the kettle cavity 10.

[0075] In this embodiment, it further includes a jacket 12 provided on the side wall of the kettle body 1. A chamber 12c is formed between the jacket 12 and the kettle body 1, and an air inlet 12a and an air outlet 12b are provided on the jacket 12.

[0076] Refer to Figure 5 , the principle of this embodiment is:

[0077] In order to better heat the reaction kettle, a jacket is provided in this embodiment. When heating the reaction kettle, hot steam can be sent into the chamber through an air pump from the air inlet, and the reaction kettle is heated.

[0078] More specifically: In this embodiment, steam is used as the heat source. Steam is delivered into the chamber through the air inlet 12a on the jacket 12. The steam releases heat in the chamber 12c, and the heat is transferred to the material in the kettle cavity 10 through the outer wall surface of the kettle body 1 for heat exchange to achieve the purpose of heating. The water formed after the steam condenses is discharged through the exhaust port 12b at the lower end of the jacket 12.

[0079] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
