Problems solved by technology

[0002] At present, the reaction furnace for the salting-out method has only one furnace body, which will interfere with the precipitation of whiskers during the stirring process, prolong the precipitation time, and reduce production efficiency; since the heating device is arranged at the bottom of the reaction furnace, each The reaction temperature of the position is different, resulting in insufficient and uneven reaction of the material; because the stirring blade of the stirring device is too large and there is only one, the material in the reaction area is not stirred sufficiently, which leads to incomplete filtering of the material, resulting in material waste of

Embodiment 1

[0016] Embodiment 1: as Figure 1-2 As shown, a compartment-type reaction furnace suitable for the salting-out method includes an upper furnace body and a lower furnace body, both of which are made of anti-corrosion and anti-rust materials, and a gate valve 8 is provided at the connection between the two. One side of the upper furnace body is provided with a feed port 2 and a cleaning port 3, and the other side is provided with a discharge port 9, and the top of the upper furnace body is provided with a safety valve 1 and a safety valve for controlling the air pressure and exhaust in the furnace. In the condensing device 10 for cooling water vapor and ammonia, an inclined filter screen 4 is provided inside the upper furnace body. Equipment 5. The heating equipment 5 is composed of electric heating elements. The electric heating elements surround the periphery of the upper furnace body and can be specifically arranged at the lower part of the upper furnace body. It can be conv...

Embodiment 2

[0018] Embodiment 2: the remainder of this embodiment is the same as the previous embodiment, wherein as figure 2 As shown, in this embodiment, the inclination angle of the filter screen 4 is set to 30°, and the mesh number of the filter screen 4 is set to 300 mesh. The stirring device 11 includes multiple groups of stirring structures, each group is composed of motors, stirring shafts and stirring blades connected in sequence, the motors extend out of the top of the upper furnace body, and the lengths of the stirring shafts in each group of stirring structures are different, corresponding to filter above the net 4. In this embodiment, two sets of stirring structures are set, wherein the stirring shafts are long and short, the long stirring shaft is located above the lower side of the filter screen 4, and the short stirring shaft is located above the higher side of the filter screen 4. Set up a few more sets of stirring structures, which can make the material react more full...

Embodiment 3

[0020] Embodiment 3: the remainder of this embodiment is the same as the previous embodiment, wherein as figure 1 As shown, the condensing device 10 is composed of condensing pipes, including vertical pipe I10-1, vertical pipe II10-2, horizontal pipe I10-3, and horizontal pipe II10-4, wherein the bottom of vertical pipe I10-1 is fixed on the upper furnace The upper end of the vertical pipe I10-1 is connected to the vertical pipe II10-2 through the horizontal pipe I10-3, and the vertical pipe II10-2 is connected to the horizontal pipe II10-4, and the horizontal pipe II10-4 is connected to the upper furnace The side wall of the body, and the horizontal pipe I10-3 and the horizontal pipe II10-4 are inclined downward along the flow direction of the medium. In this embodiment, the inclination angle of the two is set to 40°. When the material reacts in the upper furnace body When the temperature is too high, water vapor and ammonia gas will be generated, and the temperature is too h...

Abstract

The invention relates to a split bin type reaction furnace applicable to salting-out processes, and belongs to the field of chemical equipment. The split bin type reaction furnace comprises an upper furnace and a lower furnace. A sluice valve is arranged at a joint of the upper furnace and the lower furnace, a feed inlet and a cleaning opening are formed in one side of the upper furnace, a discharge opening is formed in the other side of the upper furnace, a safety valve and a condensation device are arranged on the top of the upper furnace, an oblique filter screen is arranged inside the upper furnace, a stirring device is fixed into the upper furnace and is positioned above the filter screen, heating equipment is arranged on the outer side of the upper furnace and comprises electric heating elements, and the electric heating elements are arranged around the periphery of the upper furnace; a discharge outlet is formed in the bottom of the lower furnace, and a temperature lowering device capable of carrying out cooling by circulating water is arranged in the lower furnace. The split bin type reaction furnace has the advantages that a furnace is divided into an upper portion and a lower portion by the sluice valve, the heating equipment and the stirring devices are integrated with the upper furnace, accordingly, reaction can be accelerated, and crystal dissolution can be promoted; the lower furnace is provided with cooling pipes in the shape of mosquito-repellent incense, accordingly, solution systems can be positioned in low-temperature environments, and crystals can be quickly re-crystallized.
