Description

Technical Field

[0001] The utility model relates to the technical field of alkyl hydroxamic acid purification devices, in particular to an alkyl hydroxamic acid constant temperature separation and purification device. Background Art

[0002] Alkyl hydroxamic acid is an important chemical raw material, widely used in fields such as metal extraction, especially in the extraction of metals such as gallium and germanium. However, during the preparation of alkyl hydroxamic acid, a certain amount of water and salt are often mixed in. These impurities have a negative impact on the extraction process, reducing extraction efficiency and product quality.

[0003] In order to ensure the purity of alkyl hydroxamic acid and to improve the extraction efficiency of alkyl hydroxamic acid, it is usually necessary to separate and purify the prepared alkyl hydroxamic acid. When performing the separation and purification operation, corresponding separation and purification equipment is usually used. There are many types of separation and purification equipment on the market. Most separation and purification equipment use constant temperature heating to achieve evaporation and purification of alkyl hydroxamic acid.

[0004] However, most separation and purification devices lack components that promote the mixing and flow of the raw liquid during use, hindering uniform mixing of the raw liquid in various locations and affecting the constant-temperature separation and purification effect. Some separation and purification devices also use stirring motors for stirring, but the transmission shaft of the stirring motor is prone to leakage, causing inconvenience to the user. In view of this, we propose a constant-temperature separation and purification device for alkyl hydroxamic acid. Utility Model Content

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: a constant temperature separation and purification device for alkyl hydroxamic acid, comprising a separation cylinder 1, on which a constant temperature electric heater 18 is fixedly installed, and the constant temperature electric heater 18 is used for heating operation;

[0027] Specifically, an insulation box 2 is provided on one side of the separation cylinder 1, and a plurality of constant temperature electric heating rods 20 arranged at equal intervals in a linear manner are fixedly installed on the inner wall of the insulation box 2. A serpentine tube 22 is provided inside the insulation box 2. One end of the serpentine tube 22 passes through the insulation box 2 and is fixedly installed with a clean gas inlet pipe 21, and the other end of the serpentine tube 22 passes through the insulation box 2 and is fixedly installed with a vertical tube 23. The vertical tube 23 is located in the separation cylinder 1, and a plurality of uniformly distributed tubes 24 arranged at equal intervals in a ring shape are fixedly installed on the bottom end tube body of the vertical tube 23 to ensure that when in use, the gas can be heated at the serpentine tube 22 and then passed into the separation cylinder 1, thereby promoting the flow of the raw liquid in the separation cylinder 1 and keeping the temperature of the raw liquid in each part consistent; and the constant temperature electric heater 18 and the constant temperature electric heating rod 20 are both existing conventional technologies and are not described here.

[0028] In this embodiment, the number of the uniformly distributed pipes 24 is 4 to 8, and the uniformly distributed pipes 24 are arranged to be inclined downward by 45° to 60°, so that the gas is discharged from the ends of the uniformly distributed pipes 24 and the vertical pipes 23 to various parts of the separation cylinder 1 more evenly.

[0029] Specifically, the top of the insulation box 2 is connected to the outside world, and an insulation cover 25 is fixedly installed on the top surface of the insulation box 2 by multiple fastening screws; a sealing plug 26 is fixedly installed on the bottom surface of the insulation cover 25, and the sealing plug 26 is plugged into the insulation box 2 to facilitate opening the insulation cover 25 for maintenance operations.

[0030] Furthermore, a conical cylinder 10 is fixedly mounted on the bottom end of the separation cylinder 1 , and a discharge pipe 11 is fixedly mounted on the bottom end of the conical cylinder 10 , so that the discharge operation can be performed at the discharge pipe 11 .

[0031] In addition, a raw material pipe 13 is fixedly installed on the top cylinder of the separation cylinder 1, and valves 14 are fixedly installed on the discharge pipe 11 and the raw material pipe 13, so that the valve 14 can be used to control the opening and closing operation.

[0032] It is worth noting that a plurality of support legs 12 arranged in a ring shape with equal spacing are fixedly installed on the bottom of the separation cylinder 1, and the distance between the bottom end of the discharge pipe 11 and the ground is greater than 20 cm, so that stable support operation can be achieved using the support legs 12.

At this time, the constant temperature electric heater 18 is connected to the external power supply and is put into operation. The constant temperature electric heater 18 starts to heat, and the heat is transferred to the separation drum 1, so that the raw liquid in the separation drum 1 is heated and the evaporation operation is promoted. In addition, the constant temperature electric heating rod 20 is connected to the external power supply and is put into operation. The constant temperature electric heating rod 20 starts to heat the insulation box 2, and the clean gas inlet pipe 21 is connected to the external gas inlet pipeline.

The heated gas is transported to the liquid surface in the separation drum 1 and discharged in the form of bubbles, which can promote the flow of the raw liquid and make the temperature of each part of the raw liquid consistent. In addition, after the gas is introduced, the steam in the separation drum 1 can be promoted to be discharged along the gas outlet hood 16.
