Description

Technical Field

[0001] The utility model relates to the field of chemical manufacturing, in particular to a small reaction device. Background Art

[0002] In chemical plants, powdered and liquid raw materials are often used. The liquid and powdered raw materials are fully mixed and the reaction is promoted. The mixing of liquid and powdered raw materials usually requires the use of a stirring device, but the stirring device consumes a lot of energy, such as electrical energy consumption, mechanical energy loss, heat energy loss or gas loss.

[0003] After searching application number 201921199171.6, a small-scale chemical plant mixing reaction device is provided, including a reaction chamber, a powder inlet pipe is provided on the top of the reaction chamber, a cache chamber is connected to the bottom of the powder inlet pipe, a lower powder port is provided on the side wall of the cache chamber, a reaction column is provided at the bottom of the cache chamber, a plurality of liquid inlet pipes are provided on the side wall of the reaction chamber, a plurality of nozzles are arrayed on the liquid inlet pipe, the direction of the nozzle spraying is toward the reaction column, and a discharge port is provided at the bottom of the reaction chamber. The device allows the powdered raw materials to enter the cache chamber from the powder inlet pipe, and fall along the lower powder port of the side wall of the cache chamber. At the same time, the liquid raw materials are injected from the liquid inlet pipe and sprayed outward along the nozzle. After encountering the powdered raw materials, the two are mixed together, and most of them collide with the reaction column with the impact force after mixing, and further react, and finally discharged along the discharge port, without the need for continuous stirring of the stirring device, to avoid a large amount of energy waste.

[0004] This technical solution has the following technical disadvantages:

[0005] 1. Due to the friction and cohesion between the particles of the powdered raw materials, a stable structure is formed between the powdered raw materials. If the powder outlet in the device is small, the powdered raw materials cannot fall through the outlet, just like using a colander to scoop flour, the flour cannot fall out. If the powder outlet in the device is too large, the powdered raw materials will fall quickly, and thus cannot be fully mixed with the liquid to react.

[0006] 2. In the device, liquid raw materials are injected from the liquid inlet pipe and sprayed outward along the nozzle. After encountering the powdered raw materials, the two are mixed together, and most of them collide with the reaction column with the impact force after mixing for further reaction. The reaction column is a common equipment in chemical process, which is used for chemical reaction, separation of substances or purification of products. Its principle is based on the material passing through different operating areas in the column, such as adsorption, absorption, extraction, distillation, etc., to achieve the desired reaction or separation effect. This technical means can only deliver part of the raw materials to the surface of the reaction column, so that the raw materials slowly slide down the reaction column, increasing the reaction time a little bit, and its actual effect is not great, and it is impossible to achieve a more effective reaction effect on the raw materials.

[0007] Therefore, those skilled in the art provide a small-scale reaction device to solve the problems raised in the above background technology. Utility Model Content

[0011] As a further solution of the utility model: a discharge pipe is welded to the bottom of the reaction chamber, and the discharge pipe is communicated with the interior of the reaction chamber.

[0012] As a further solution of the utility model: three legs are arranged in a ring at equal angles on the outer wall of the reaction chamber, and the three legs are welded to the outer wall of the reaction chamber near the lower end.

[0014] As a further solution of the utility model: slide grooves are provided on the inner walls on the left and right sides of the feed port, and a storage cavity is provided on the inner wall on the rear side of the feed port.

[0015] As a further solution of the utility model: sliding bars are fixedly installed on the left and right sides of the cavity door by screws, and the sliding bars are located inside the sliding groove and are slidably connected to the inner wall of the sliding groove.

[0016] Compared with the prior art, the utility model provides a small reaction device, which has the following technical effects and advantages:

[0017] 1. In the utility model, the powdered raw materials are first stored in the buffer chamber. Due to the presence of certain friction and cohesion between the particles of the powdered raw materials, a stable structure is formed between the powdered raw materials, so that the powdered raw materials will not fall through the small through holes on the buffer plate. After the fan is started, a negative pressure is formed on the top through the rotation of the fan, so that the powdered raw materials can slowly fall through the small through holes on the buffer plate, and then be blown into the reaction chamber by the fan, and at the same time, the liquid raw materials are sprayed out through the atomizing nozzle, so that the two sides can be fully contacted and mixed.

[0018] 2. The device is also provided with an extended reaction plate. When the powdered raw materials and the liquid raw materials are initially mixed above, they will fall to the top of the extended reaction plate. A number of fine tubes are provided on the extended reaction plate. Due to the effect of surface tension, the powdered raw materials and the liquid raw materials will not immediately penetrate the fine tubes and fall below after mixing, but will climb upward along these tiny holes to form a curved surface. Due to the effect of gravity, when accumulated to a certain extent, they will gradually drip from the fine holes, so that the powdered raw materials and the liquid raw materials can be fully mixed and reacted on the extended reaction plate.
