Description

Technical Field

[0001] The utility model relates to the technical field of potassium sulfate production equipment, in particular to a material pushing device of a potassium sulfate reaction furnace. Background Art

[0002] The Mannheim process is a widely used method for producing potassium sulfate. Concentrated sulfuric acid and potassium chloride react in the reaction chamber of the Mannheim furnace to produce potassium sulfate and HCL gas. After concentrated sulfuric acid and potassium chloride are put into the reaction chamber, the stirring device in the reaction chamber stirs the materials to fully react. At the same time, as the materials are continuously added, the stirring device will also push the potassium sulfate generated by the reaction to the edge of the reaction chamber to discharge and complete the discharge. The stirring device generally adopts a rake tooth structure, in which vertically downward rake teeth are set on the horizontally set rake arm. The rake arm rotates along its midpoint to drive the rake teeth, which plays the role of stirring and pushing the material;

[0003] Existing rake teeth generally adopt blade-shaped shapes, with thick upper parts and narrow lower parts. The advantage of this shape is that it is conducive to breaking the material layer, which can play a certain role in crushing and is conducive to the smooth progress of stirring. However, due to the blade-shaped shape, after the material layer is broken, after the rake teeth pass, the material layer behind the rake teeth is easy to aggregate to a certain extent, and this aggregated material layer is still the original material close to each other, so the effect of mixing materials at different positions is not good, and it is not conducive to the turning over of the bottom material, which is not conducive to sufficient mixing and improving the reaction efficiency.

[0004] For example, the Chinese authorized patent with announcement number CN 216005236 U (a stirring and pushing device for a potassium sulfate reactor): Since the main stirring part adopts a blade structure at the top and a plow-type structure at the bottom, while maintaining the crushing capacity, the plow-type structure can relatively turn the bottom material layer upward, thereby improving the mixing efficiency of the materials and facilitating the full reaction. Especially for the reaction chamber heated from the bottom, since the bottom material layer is more easily heated than the upper material layer, the improvement in reaction efficiency is more obvious. This technical solution solves the above problem;

[0005] However, the technical solution of the utility model still has some technical problems. When the stirring and pushing device of the potassium sulfate reactor is in use, due to the low working area of ​​the main stirring part, when there are more materials inside the reactor, the upper materials inside the main stirring part cannot be well mixed, which results in great limitations in the use of the stirring and pushing device of the potassium sulfate reactor and affects the rapid mass production of potassium sulfate.

[0006] Therefore, a material pushing device for a potassium sulfate reactor is proposed. Utility Model Content

[0007] The utility model aims to provide a pushing device for a potassium sulfate reactor, so as to solve the problem that when the stirring and pushing device for the potassium sulfate reactor proposed in the above background technology is in use, due to the low working area of ​​the main stirring part, when there are more materials inside the reactor, the upper layer materials inside the main stirring part cannot be well mixed, resulting in greater limitations in the use of the stirring and pushing device for the potassium sulfate reactor, and affecting the rapid mass production of potassium sulfate.

[0008] To achieve the above purpose, the utility model provides the following technical solution: a pushing device for a potassium sulfate reactor, comprising a rotating shaft, characterized in that:

[0009] The material turning and mixing plates are arranged on both sides of the rotating shaft, the rotating shaft is welded to the material turning and mixing plates, fourteen material turning and mixing plates are arranged, and heating strips are installed on the inner sides of the fourteen material turning and mixing plates;

[0010] A top connecting plate is arranged at the upper end outside the rotating shaft, the rotating shaft is welded to the top connecting plate, a material distribution mesh cylinder is installed at the lower end of the top connecting plate, the material distribution mesh cylinder is welded to the top connecting plate and the material turning and mixing plate, and a hot air channel is arranged inside the material distribution mesh cylinder.

[0012] Preferably, the internal heating tube is fixedly connected to the heating strip, and fourteen heating strips are provided.

[0013] Preferably, a connecting wire is installed at the lower end of the internal heating tube, and the connecting wire is fixedly connected to the internal heating tube.

[0017] 1. The utility model can turn over materials at different heights inside the potassium sulfate reactor in large quantities by installing twelve turning and mixing plates, so that the material mixing is faster, and at the same time, the temperature of the materials at different heights inside the potassium sulfate reactor is more uniform, thereby enhancing the use effect of the device and enabling the potassium sulfate reactor to carry out large-scale and efficient production. The installation of heating strips and internal heating tubes can heat the materials when the device turns and pushes the materials, so that the materials are heated up faster, which is conducive to the large-scale and high-speed production of potassium sulfate and improves the production efficiency of potassium sulfate;

[0018] 2. The utility model installs a material dividing mesh cylinder, which can make the material be divided twice when it is shifted, thereby improving the use effect of the device. At the same time, the hot air channel arranged inside the material dividing mesh cylinder can transfer the hot air in the lower material inside the potassium sulfate reactor upward, so that the upper material inside the potassium sulfate reactor can be better heated up and the temperature of the material can be more uniform.
