Description

Technical Field

[0001] The utility model relates to the technical field of chemical solid particle production, in particular to a movable spraying device suitable for a drum granulator. Background Art

[0002] In the current production of most chemical products, especially solid particle products, a drum granulation mechanism is required to pre-treat the materials. In traditional operations, it is necessary to manually prepare a special solution and then manually move the spray bracket to spray the material. This has certain disadvantages. For example, errors are prone to occur when manually preparing the solution, and the spraying rate and time cannot be controlled. There are cases where the spray is not in place. Some materials absorb the liquid while others do not, which affects the absorption effect of the material and thus the product quality. Secondly, the operation steps are relatively complicated, the labor intensity is high, the production efficiency is low, and the production cycle is extended. Thirdly, the safety is low. Since most chemical products contain corrosive raw and auxiliary materials in the production process, there is a risk of corrosion when operating the equipment.

[0003] In the prior art, the utility model patent with patent number CN202022374417.8 discloses a spray device used in a drum-type granulator, including a granulation drum, a first support frame, a second support frame, a third support frame, a first spray member, a first rotating joint, and a spray drive motor; the first support frame and the second support frame are arranged in parallel at one end of the granulation drum; the third support frame is arranged in parallel with the other end of the granulation drum; the first spray member passes through the granulation drum and is installed on the second support frame and the third support frame, and the first spray member is rotatably connected to the second support frame and the third support frame respectively; one end of the first rotating joint is connected to the first spray member, and the other end of the first rotating joint is installed on the first support frame; the spray drive motor is installed on the first support frame and is transmission-connected to the first spray member; wherein, the first spray member is provided with multiple injection points along the axial side.

[0004] The above patent describes a spray device used in a drum granulator. By setting a first spray part to pass through the granulation drum, multi-point spraying can be achieved, and then hot water or steam can be evenly sprayed into the granulation drum, so that the material in the granulation drum is evenly affected by water or steam. However, before spraying, workers need to strictly proportion the spray liquid before spraying. However, in the chemical production process, some chemical raw materials are corrosive, which will not only cause harm to workers, but also may lead to inaccurate proportions and affect subsequent production results. The above device lacks an automatic liquid dispensing device. During use, workers are not only required to prepare the spray liquid in advance, but also to manually add the spray liquid in time to prevent the spray liquid from running out and causing the production line to stop. Further improvement is needed. Utility Model Content
