Description

Technical Field

[0001] The utility model belongs to the technical field of activated alumina preparation, and relates to a homogeneous reactor, in particular to a homogeneous reactor for preparing automotive-grade activated alumina. Background Art

[0002] Homogeneous reaction is also called single-phase reaction, that is, a chemical reaction that occurs in only one phase (gas phase, liquid phase or solid phase). Its characteristic is that there is no phase interface in the reaction system. For example, high-temperature thermal cracking of hydrocarbons to produce ethylene is an important gas-phase homogeneous reaction. Acid-base neutralization, esterification, saponification and other reactions are typical liquid-phase homogeneous reactions. When the homogeneous reactor is in use, the reactor needs to be installed on the mounting ring inside the homogeneous reactor. The operation of the homogeneous reactor drives the reactor to rotate and heat, so that the substances in the reactor are in the same phase of chemical reaction.

[0003] Most of the existing methods of rotating reactors in homogeneous reactors adopt one of two methods: multiple reactors rotate on their own or multiple reactors revolve around a certain axis. There are problems such as insufficient stirring and uneven mixing of materials in the reactors, and they cannot meet the production process requirements of automotive-grade activated alumina. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a homogeneous reactor for preparing automotive-grade activated alumina, which allows the reactor to rotate while revolving, so that the materials in the reactor are fully mixed to meet the production process requirements of automotive-grade activated alumina.

The plurality of rotating drum groups are driven by a first motor fixedly arranged on one side of the casing and revolve around the central axis of the casing. The rotating drum group is composed of a plurality of rotating drums connected in series for adapting to a fixed reaction kettle. The plurality of rotating drum groups are respectively driven to rotate by a plurality of second motors fixedly mounted on the casing.

[0007] Furthermore, it also includes a base, on which a first support rod and a second support rod relative to each other are provided, the first motor is fixedly mounted on the first support rod, the second support rod is provided with a first bearing, and both ends of the central axis of the box body are respectively connected to the first motor and the first bearing through a first rotating shaft.

[0008] Furthermore, a plurality of second bearings corresponding to the plurality of rotating drum groups are fixedly connected to one side of the box body, and adjacent rotating drums, the rotating drum and the second motor, and the rotating drum and the second bearings are all connected via a second rotating shaft.

[0009] Furthermore, a fixed cylinder is sleeved on the outer side of the rotating cylinder, the rotating cylinder is rotatably connected to the fixed cylinder, and the fixed cylinder is fixedly installed on the inner wall of the box body through a connecting block.

[0010] Furthermore, a plurality of balls are evenly distributed between the rotating cylinder and the fixed cylinder.

[0011] Furthermore, the plurality of second motors are respectively fixedly connected to the first rotating shaft through a plurality of third support rods.

[0012] Beneficial effects of the utility model: the homogeneous reactor for preparing automotive-grade activated alumina provided by the present application is achieved by connecting multiple rotating drums for adapting to fixed reactors in series into a rotating drum group, and arranging multiple rotating drum groups along the circumference of the central axis of the housing in the housing, and the multiple rotating drum groups are all driven by a first motor fixedly arranged on one side of the housing, and revolve around the central axis of the housing, thereby realizing a stirring function for the original static reaction in the reactor, so that the materials are mixed evenly, which can effectively promote the reaction effect; at the same time, the multiple rotating drum groups are respectively driven to rotate by multiple second motors fixedly mounted on the housing, so that the reactor adapted to be loaded into the rotating drum rotates while revolving around the central axis of the housing, further strengthening the stirring function of the reaction in the reactor, thereby further promoting the reaction effect; when preparing automotive-grade activated alumina, only a 100ml reactor needs to be placed in the homogeneous reactor for rotation, so that the materials can be mixed evenly to meet the production process requirements.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1As shown, the utility model provides a homogeneous reactor for preparing automotive-grade activated alumina, comprising a housing 1 and a plurality of rotating drum groups 4 arranged in the housing 1, wherein the rotating drum group is composed of a plurality of rotating drums 41 connected in series for adapting and fixing the reaction kettle 3, wherein four groups of rotating drum groups 4 with a total of twelve hydrothermal synthesis reaction kettles 3 of different sizes can be placed in the housing 1 according to user requirements, and the reaction kettle 3 is adapted to be loaded into the rotating drum 41 and can be tightened and fixed by a horn screw arranged on one side of the rotating drum 41, and two adjacent groups of rotating drum groups 4 are vertically distributed, so that the temperature and pressure in the housing 1 are adjusted and controlled to achieve the following reaction conditions:

[0017] (1) The reaction of different material ratios at the same temperature, pressure and time.

[0018] (2) Reaction of the same material ratio at the same temperature, the same pressure and different time. Here, different time means taking out or loading a certain reaction kettle 3 at random according to the set reaction time conditions, and the rest continue to react according to the setting.

[0019] Multiple rotating drum groups 4 are arranged in a circular array along the central axis of the housing 1, and are driven by a first motor 21 fixedly mounted on one side of the housing 1 to revolve around the central axis of the housing 1. The first motor 21 can achieve stepless speed regulation, and achieve a stirring function for the static reaction in the original reactor 3, so that the materials are mixed evenly, which can effectively promote the reaction effect. Multiple rotating drum groups are driven to rotate by multiple second motors 22 fixedly mounted on the housing 1, respectively, so that the reactor 3 adapted to be loaded into the rotating drum 41 rotates while revolving around the central axis of the housing 1, further strengthening the stirring function of the reaction in the reactor 3, thereby further promoting the reaction effect.

[0020] Specifically, the homogeneous reactor also includes a base 5, on which a first support rod 51 and a second support rod 52 are provided relative to each other, a first motor 21 is fixedly mounted on the first support rod 51, and a first bearing 53 is provided on the second support rod 52. The two ends of the central axis of the box body 1 are respectively connected to the first motor 21 and the first bearing 53 through the first rotating shaft 11, so that the box body 1 is driven to rotate along its central axis by the first motor 21.

[0021] A plurality of second bearings 12 corresponding to the plurality of drum groups are fixedly connected to one side of the housing 1, and the adjacent drums 41, the drum 4 and the second motor 22, and the drum 4 and the second bearing 12 are all connected via the second rotating shaft 13. Thus, a plurality of drums 41 in a drum group 4 are driven to rotate synchronously by one second motor 22. The plurality of second motors 22 are respectively fixedly connected to the first rotating shaft 11 via a plurality of third support rods 14, so as to increase the reliability of the second motor 22 when rotating around the central axis of the housing 1.

[0022] like Figure 2As shown, a fixed cylinder 42 is sleeved on the outer side of the rotating cylinder 41, and the rotating cylinder 41 is rotatably connected to the fixed cylinder 42.

A plurality of balls 44 are evenly distributed between the rotating cylinder 41 and the fixed cylinder 42 to reduce the resistance encountered by the rotating cylinder 41 when rotating.

[0023] The homogeneous reactor also includes a control box 54 mounted on the base 5. The control box 54 uses a fuzzy PID intelligent control instrument, which can control the box 1 to achieve normal operation within a temperature range of room temperature to 250 degrees Celsius, with a temperature control accuracy of ±0.5 degrees Celsius. Four universal wheels 55 are installed at the bottom of the base 5 to facilitate moving the homogeneous reactor to different working positions.
