Description

a crystallization kettle

technical field

The utility model belongs to the technical field of chemical equipment, in particular to a crystallization kettle.

Background technique

The crystallization kettle is widely used in chemical industry, medicine and other fields after the material is mixed and reacted. The interlayer requires chilled water or refrigerant water to cool down sharply. The structural form of the agitator and the material outlet form, the high-precision polishing inside the tank, and the requirements for cleaning without dead ends in the tank meet the process conditions. The existing crystallization kettles basically use jackets for cooling. The heat exchange area of the jackets is not large, the fluid flow rate is small, and the heat transfer coefficient is not high, which leads to uneven cooling of the materials and affects the crystallization morphology. In addition, at present, the outlet of the lower gate valve is small and the discharge is slow. When the crystallization kettle used is viscous, the feed liquid will easily block the pipeline between the discharge port and the lower gate valve during the crystallization process, and the material will condense into blocks and flow. The property is poor, and some materials are easy to stick to the wall of the crystallization kettle. These shortcomings cause a lot of inconvenience to industrial production.

A crystallization kettle, comprising a rounded truncated kettle body and a stirring device arranged on the kettle body, a feed inlet is arranged on the upper part of the kettle body, and a discharge port is arranged on the lower part of the kettle body, The stirring device includes a motor arranged outside the kettle body, a stirring shaft extending into the kettle body, and a stirring blade arranged at the bottom of the stirring shaft, and a truncated inner cavity is also provided in the kettle body body, a water cavity is arranged in the inner cavity, a disc is arranged under the inner cavity, and there is a space between the upper end surface of the inner cavity and the upper bottom of the kettle body, and the inner cavity There is a space between the lower end surface of the cavity and the disc, the stirring shaft extends into the inner cavity, and the stirring blade leaves a space between the lower end surface of the inner cavity and the disc. Rotate in some space.

Further, a refrigerant inlet and a refrigerant outlet are provided on the kettle body, and the water cavity communicates with the refrigerant inlet and the refrigerant outlet.

Specifically, the length of the stirring blade is less than or equal to the outer diameter of the lower end surface of the inner cavity.

Specifically, the diameter of the disc is greater than or equal to the inner diameter of the lower end surface of the inner cavity.

Specifically, the inner cavity is fixed in the still body by a bracket.

Specifically, the disc is fixed in the kettle body through a bracket.

The cooling efficiency provided by the utility model is high, the crystallization effect is good, and the crystallization efficiency of materials is improved.

detailed description

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

In a specific embodiment, as shown in Figure 1, a crystallization kettle includes a rounded truss-shaped kettle body 1 and a stirring device 2 arranged on the kettle body 1, and a feed inlet 101 is provided on the top of the kettle body 1 , the bottom of the still body 1 is provided with a discharge port 102, and the stirring device 2 includes a motor 201 arranged outside the still body 1, a stirring shaft 202 extending into the still body 1, and a stirring blade 203 arranged at the bottom of the stirring shaft 202 ,

In the kettle body 1, there is also a rounded frustum-shaped inner cavity 3, and a water chamber 4 is arranged in the inner cavity 3, and a refrigerant inlet 6 and a refrigerant outlet 7 are arranged on the kettle body 1, and the water chamber 4 is connected to the refrigerant inlet 6. and refrigerant outlet7.

A disc 5 is arranged below the inner cavity 3, a space is left between the upper end surface of the inner cavity 3 and the upper bottom of the kettle body 1, and a space is left between the lower end surface of the inner cavity 3 and the disc 5, The stirring shaft 202 extends into the inner cavity 3 , and the stirring blade 203 rotates in the space left between the lower end surface of the inner cavity 3 and the disc 5 . The length of the stirring blade 203 is smaller than the outer diameter of the lower end surface of the inner cavity 3 . The diameter of the disc 5 is larger than the inner diameter of the lower end surface of the inner cavity 3 .

Both the inner cavity body 3 and the disc 5 are fixed in the kettle body 1 through a bracket 8 .

During the working process of the crystallization kettle provided by the utility model, the solution in the inner cavity first crystallizes and deposits on the disk. The crystals on the disk are scraped by the stirring blades, leave the disk, and deposit at the bottom of the crystallization kettle, so as to achieve the separation of the crystals from the saturated solution and promote the crystallization process to proceed smoothly, quickly and evenly.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
