Description

Technical Field

[0001] The utility model relates to an adsorbent powder dripping granulation device. Background Art

[0002] Adsorbent is a solid substance that can effectively absorb certain components from gas or liquid. Most commonly used adsorbents are made into granules for the convenience of users. Therefore, granulators are often used in the production process of adsorbents. At present, most of the methods for producing adsorbent particles are extrusion granulation. The so-called extrusion granulation is to add the dry binder and adsorbent into the extruder hopper after sufficient stirring and mixing. There is a heater outside the extrusion barrel, and the material in the barrel is heated to the melting temperature through heat conduction. The machine is running, and the screw in the barrel conveys the material forward. During the movement, the material rubs and shears with the barrel, the screw, and the materials, generating a lot of heat. The heat and heat conduction make the added material melt continuously. The molten material is continuously and stably conveyed to the die head (or die) with a certain shape. After passing through the die, the material in the flowing state takes an approximate die shape, and then enters the cooling and shaping device to keep the material in a predetermined shape and solidify. Then the extruded and shaped material is input into the granulator to cut the round strip plastic into particles. However, the current extrusion equipment is expensive, and there are problems such as ugly product shape, difficult to ensure quality, low production capacity, large mold wear, low particle strength, and dust pollution. Other problems that may be encountered during the extrusion granulation process include hollowness and material overflow, which may be caused by improper processing temperature, incomplete plasticization of materials, and increased clearance between the screw and the barrel. The existence of these problems further affects the efficiency and product quality of extrusion granulation, increases production costs, and puts higher requirements on equipment maintenance and operation.
