Description

Technical Field

[0001] This utility model belongs to the field of ferrous chloride preparation technology, and in particular relates to a pneumatic stirring device for the preparation of ferrous chloride. Background Technology

[0002] Ferrous chloride is an inorganic compound that appears as green crystals or powder. It is widely used in metallurgy, chemical industry, and environmental protection. It is commonly used to prepare iron salts, water purification agents, and catalysts. For example, it is used as a flocculant to remove impurities in wastewater treatment, or as a catalyst for Friedel-Crafts reactions to promote organic synthesis.

[0003] In the preparation of ferrous chloride, a stirring device is usually required to mix the powder and solution. Although the existing stirring device can achieve the stirring effect, some powder and solution do not react completely, which requires secondary filtration of the discharged solution, increasing the workload. Therefore, a pneumatic stirring device for the preparation of ferrous chloride is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic stirring device for the preparation of ferrous chloride. By removing the bottom cover, the filter cylinder can be removed, making it easy to recover unreacted iron powder for reuse. At the same time, during discharge, the stirring shaft drives the movable shaft to rotate, and the movable shaft stirs inside the filter cylinder, preventing the filter cylinder from being blocked, improving discharge efficiency, and solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A pneumatic stirring device for the preparation of ferrous chloride includes: a tank body, a top cover fixed to the top of the tank body by bolts, an inclined filter tube fixedly connected to the bottom of the tank body, a horizontally arranged discharge pipe fixedly connected to one side of the filter tube, the bottom of the filter tube being open and threadedly connected to a bottom cover, a support column fixedly connected to the top of the bottom cover, a filter cylinder fixedly connected to the top of the support column, a gap being provided between the filter cylinder and the inner wall of the filter tube, and a limiting ring fixedly connected to the top of the filter cylinder, the limiting ring contacting the inner wall of the filter tube. After discharge, the filter cylinder can be removed by removing the bottom cover, thereby facilitating the recovery of unreacted iron powder for reuse and reducing workload.

[0007] A stirring mechanism, which is installed inside the tank, is used to stir the raw materials.

[0008] A feeding mechanism, which is disposed on the surface of the top cover, is used to feed materials into the tank.

[0009] A heating mechanism is provided at the bottom of the tank for heating the solution.

[0010] As a further embodiment of this utility model, the stirring mechanism includes an inclined stirring shaft with the center line of the stirring shaft being the same as the center line of the filter tube. At least one set of stirring blades are fixedly installed on the circumference of the stirring shaft. The stirring shaft is rotatably connected to the top of the top cover and passes through the top cover. A pneumatic motor is fixedly connected to the surface of the top cover, and one end of the output shaft of the pneumatic motor is fixed to the stirring shaft.

[0011] As a further embodiment of this utility model, an eccentrically positioned movable shaft is fixedly connected to the bottom of the stirring shaft. The movable shaft is located inside the filter cylinder. By installing the eccentrically positioned movable shaft at the bottom of the stirring shaft, the stirring shaft drives the movable shaft to rotate during discharge. The movable shaft stirs inside the filter cylinder, preventing the filter cylinder from being blocked and improving the discharge efficiency.

[0012] As a further embodiment of this utility model, the feeding mechanism includes a screw feeder, which is fixed to the top of the top cover and its discharge end passes through the top cover. The screw feeder is driven by a pneumatic motor.

[0013] As a further embodiment of this utility model, the feeding mechanism also includes a liquid inlet pipe, which is fixed to the top of the top cover and penetrates the top cover.

[0014] As a further embodiment of this utility model, a partition is fixedly connected to the inner wall of the tank, and a through air outlet is opened on the surface of the partition. An installation cylinder is fixedly connected to the top of the air outlet, and filter cotton is placed inside the installation cylinder. A through exhaust pipe is fixedly connected to the top of the top cover, and the discharge end and the liquid inlet pipe of the screw feeder both pass through the partition.

[0015] As a further embodiment of this utility model, the heating mechanism includes a ceramic tube fixed to the inner wall of the bottom of the tank, and a heating wire is fixedly installed inside the ceramic tube.

[0016] As a further improvement of this utility model, a viewing window is provided on one side of the tank.

[0017] In this application, when used, The solution is injected into the tank through the inlet pipe. After injection, the pneumatic motor and heating wire are started. Then, the processed iron powder is fed into the tank in excess by the screw feeder. The pneumatic motor drives the stirring shaft and blades to rotate, thereby mixing the raw materials. At the same time, the heating wire heats the raw materials in the tank to improve the reaction efficiency. After the reaction is completed, the solution is cooled down and discharged. The unreacted iron powder is filtered out by the filter cartridge. After the solution is discharged, the filter cartridge can be removed by removing the bottom cover, which allows for easy recovery of the unreacted iron powder for reuse. During discharge, the stirring shaft drives the movable shaft to rotate, and the movable shaft stirs inside the filter cartridge to prevent the filter cartridge from being blocked and improve discharge efficiency.

[0018] The embodiments of this utility model have the following beneficial effects:

[0019] In this utility model, by installing a filter cartridge inside the filter tube, the filter cartridge can be removed by removing the bottom cover after the material is discharged, thereby facilitating the recovery of unreacted iron powder for reuse.

[0020] In this invention, by installing an eccentrically positioned movable shaft at the bottom of the stirring shaft, the stirring shaft drives the movable shaft to rotate during discharge. The movable shaft stirs inside the filter cylinder, preventing the filter cylinder from being blocked and improving discharge efficiency.

[0021] In this invention, the filter cylinder can be removed by taking off the bottom cover, which makes it easy to recover the unreacted iron powder for reuse. At the same time, during discharge, the stirring shaft drives the movable shaft to rotate, and the movable shaft stirs inside the filter cylinder, which prevents the filter cylinder from being blocked and improves the discharge efficiency.
