Description

Technical Field

[0001] The utility model relates to the technical field of manganese sulfate crystallization, and specifically relates to a continuous evaporation and crystallization device for manganese sulfate. Background Technique

[0002] Manganese sulfate is an inorganic compound that is soluble in water and insoluble in ethanol. Manganese sulfate crystals can be prepared by heating and evaporation. When preparing manganese sulfate crystals, a continuous evaporation and crystallization device for manganese sulfate is used. However, there are still some disadvantages in the existing continuous evaporation and crystallization device for manganese sulfate. For example, the inside of the evaporation and crystallization device heats the mother liquor through heating plates arranged on both sides of the inner cavity. Although this heating method is simple, it cannot quickly and comprehensively heat the mother liquor. At the same time, the device does not have a preheating function inside before evaporation and crystallization. After the mother liquor and materials are added to the inside of the device, it still takes a certain amount of time to heat the inside of the device, which is very time-consuming. Therefore, we propose a continuous evaporation and crystallization device for manganese sulfate. Content of the Utility Model

[0017] Embodiment 1:

[0018] Please refer to Figure 1-2, the present utility model provides a technical solution: a continuous evaporation crystallization device for manganese sulfate, which is a device that evaporates and crystallizes manganese sulfate by heating, including an evaporation kettle 1. Support legs 2 are arranged around the bottom of the evaporation kettle 1. A feed inlet 3 is arranged at the left top of the evaporation kettle 1. Through the feed inlet 3, materials can be added into the inner cavity of the evaporation kettle 1. A top cover 6 is installed on the top of the evaporation kettle 1. The connection manner between the evaporation kettle 1 and the top cover 6 has been proposed in the prior art in the application number: CN202220673586.8 (a device for continuous crystallization of manganese sulfate by heating crystallization), so it will not be described in detail in this text. Fixed rods 7 are vertically arranged on the left and right sides of the top of the inner cavity of the top cover 6. At the bottom of the fixed rods 7, top mounting plates 8 are arranged. Heating plates 1 are arranged at the bottom of the top mounting plates 8. Before the evaporation and crystallization treatment, the inner cavity of the evaporation kettle 1 can be preheated by turning on the heating plates 1, which can shorten the treatment time of evaporation and crystallization. A low-speed motor 10 is arranged at the center of the top of the top cover 6. The bottom of the low-speed motor 10 penetrates through the top of the top cover 6 and is provided with a motor shaft 11. A transmission rod 12 is arranged at the bottom of the motor shaft 11. A cross bar 13 is horizontally arranged at the bottom of the transmission rod 12. Stirring rods 14 are arranged on the left and right sides of the bottom of the cross bar 13. The low-speed motor 10 drives the stirring rods 14 arranged on both sides to rotate through the motor shaft 11, the transmission rod 12 and the cross bar 13, so as to stir the mother liquor during heating and make the mother liquor heat more evenly. A heating rod 17 is vertically arranged at the center of the bottom of the evaporation kettle 1. The heating rod 17 can heat the mother liquor comprehensively from top to bottom from the center of the mother liquor. An installation port 18 is arranged at the right top of the evaporation kettle 1. An exhaust pipe 19 is arranged on the right side of the installation port 18. One end of the exhaust pipe 19 away from the evaporation kettle 1 can be connected to a steam power generation device, which can achieve the effect of energy conservation and environmental protection.

[0019] Among them, preferably, bottom mounting plates 15 are arranged on the left and right sides of the bottom of the inner cavity of the evaporation kettle 1. Heating plates 2 are arranged on the top of the bottom mounting plates 15. Before the evaporation and crystallization, the bottom of the inner cavity of the evaporation kettle 1 can be preheated by turning on the heating plates 2.

Through the arranged thermometer 4, it is convenient for the staff to observe the temperature inside the evaporation kettle 1 in real time. An observation window 5 is arranged at the bottom of the front end face of the evaporation kettle 1. Through the arranged observation window 5, it is convenient for the staff to observe the situation inside the evaporation kettle 1 at any time.

[0021] Preferably, the heating rod 17 is set as a wavy heating rod, and the length of the heating rod 17 from top to bottom is greater than half of the length of the evaporation kettle 1 from top to bottom. Such a setting can comprehensively heat the mother liquor.

[0022] Example 2:

[0023] Refer to Figure 1 , the difference between this embodiment and the first embodiment is that: fixed blocks are arranged on the left and right sides at the top of the front and rear end faces of the evaporation kettle 1, and hoisting rings are arranged at the ends of the fixed blocks far away from the evaporation kettle 1. The whole device can be conveniently hoisted by hoisting equipment through the arranged hoisting rings; a matching sealing cover is arranged on the left side of the feed inlet 3. The arranged sealing cover can seal the feed inlet 3 after the addition of materials is completed, so as to reduce heat loss. A control valve is arranged at the end of the exhaust pipe 19 far away from the installation port 18. The arranged control valve can close the exhaust pipe 19 in the early stage of heating to avoid heat loss.

[0024] The electrical appliances mentioned in this article are all connected to an external power supply through wires.
