Technical Field
[0001] This utility model relates to the field of spray granulation drying technology, and to a modular spray granulation drying chamber that is easy to clean. Background Technology
[0002] In the practical application of spray granulation drying technology, the drying chamber is the core place for material drying and particle formation. Its cleanliness directly affects product quality, production efficiency and equipment life. However, in the long-term use of traditional spray granulation drying chambers, a series of pain points related to cleaning and maintenance have been gradually exposed, which have become key factors restricting the continuity and stability of production.
[0003] According to the public announcement (CN218608054U), a spray drying and granulation integrated machine is disclosed. This technology discloses a technical solution that includes "a base, a first fixed frame installed on the top of the base, a drying chamber provided on the first fixed frame, a nozzle provided on the top of the inner cavity of the drying chamber, a sealing cover provided above the nozzle, a drying pipe provided on the lower side of the inner cavity of the drying chamber, an air outlet provided on the top of the drying pipe, a preheating chamber provided on the side wall of the drying chamber, and the top of the preheating chamber communicating with the inner side of the sealing cover, a processing chamber connected to the bottom of the preheating chamber, a granulation chamber connected below the drying chamber, a spray gun provided in the granulation chamber, a collection box provided below the granulation chamber, and the top side of the collection box connected to the bottom of the processing chamber through a pipe, etc. This solution has the advantages of simple structure, reasonable design, rapid drying and granulation, and the ability to circulate hot air and save energy."
[0004] In the aforementioned comparative documents, although the equipment features a simple structure, reasonable design, rapid drying and granulation capabilities, and the ability to recycle hot air to save energy, during use, high-humidity atomized droplets are prone to adhering to the inner wall of the cavity, the area around the feed inlet, and the internal support structure due to problems such as turbulent airflow and uneven temperature distribution. This results in residues that are difficult to clean. Since the cavity cannot be quickly disassembled, cleaning requires manual entry for wiping or rinsing with a fixed spray device. However, manual operation is limited by the cavity space, making it difficult to reach corners, support connections, and other dead corners. The fixed spray device also cannot cover all areas, leading to incomplete cleaning. The accumulation of material residues not only affects the purity of the next batch of products but also requires extensive preparation before each cleaning due to the lack of a convenient disassembly mechanism. During the cleaning process, the inconvenience caused by the fixed structure also needs to be addressed, making a single cleaning often take several hours or even longer, significantly extending the equipment downtime and seriously affecting production efficiency.
[0005] To address the aforementioned issues, this application proposes a modular spray granulation drying chamber that is easy to clean. Utility Model Content
[0006] This invention addresses the technical problems existing in the prior art by providing a modular spray granulation drying chamber that is easy to clean.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A modular spray granulation drying chamber that is easy to clean includes a mounting frame, a support frame fixedly connected to the top of the mounting frame, a feeding chamber provided on the top of the support frame, an outer shell provided on the top plate of the mounting frame, an inner barrel provided inside the outer shell, a connecting barrel fixedly connected to the mounting frame, the top of the connecting barrel fitting against the bottom of the inner barrel, a heat-conducting chamber detachably connected to the bottom of the connecting barrel, a granulation chamber detachably connected to the bottom of the heat-conducting chamber, a collection box provided on the bottom plate of the mounting frame, the top of the collection box communicating with the bottom of the granulation chamber, a motor fixedly connected to the side wall of the support frame, a bidirectional threaded rod fixedly connected to the shaft of the motor, the end of the mounting frame away from the motor being rotatably connected to the support frame, a threaded block being threadedly connected to the outer wall of the bidirectional threaded rod, and one end of the threaded block being fixedly connected to the outer wall of the outer shell.
[0008] The mounting frame has a placement slot at the top, and a rotating rod is rotatably connected to the mounting frame through the placement slot. A sliding plate is slidably connected to the mounting frame through the placement slot. The bottom of the sliding plate is in contact with the outer wall of the rotating rod, and the top of the sliding plate is fixedly connected to the bottom of the outer shell. By setting the placement slot, rotating rod, and sliding plate, convenient movement of the outer shell can be achieved.
[0009] The bottom of the sliding plate is fixedly connected to a slide bar, and the bottom of the slide bar fits into the placement groove opened in the mounting frame. By setting the slide bar, the sliding plate is stabilized, and the sliding plate is prevented from tilting when supporting the outer shell, thereby avoiding affecting the support of the outer shell for the inner barrel.
[0010] A connecting plate is fixedly connected to the side wall of the support frame. A limiting rod is fixedly connected to the side of the connecting plate near the outer shell. The limiting rod is slidably connected to the outer shell. By setting the connecting plate and the limiting rod, the outer shell is limited, thereby preventing the outer shell from shifting position when moving, thus avoiding affecting the opening and closing of the outer shell.
[0011] The outer wall of the inner tub is fixedly connected with a retaining ring. The inner wall of the retaining ring fits against the outer wall of the limiting rod. By setting the retaining ring, the inner tub is positioned, which facilitates the installation of the inner tub after disassembly.
[0012] A fixing rod is fixedly connected to the inner wall of the outer shell. One end of the fixing rod is attached to the outer wall of the inner tub. By setting the fixing rod, the inner tub is stabilized. When the inner tub is in use, the fixing rod can support the inner tub to avoid affecting its use.
[0013] A sealing ring is fixedly connected to the outer wall of the outer shell, and a sealing gasket is fixedly connected to the inner wall of the sealing ring. The inner wall of the sealing gasket is in contact with the outer wall of the feeding chamber. By setting the sealing ring and the sealing gasket, the contact between the outer shell and the feeding chamber is sealed, thereby preventing material or hot air from flowing out through the contact between the outer shell and the feeding chamber, thus avoiding affecting the granulation efficiency.
[0014] The beneficial effects of this utility model are:
[0015] By using a combination of mounting brackets, support brackets, feeding chamber, outer shell, inner barrel, motor, bidirectional threaded rod, and threaded block, the drying chamber of the spray granulation dryer can be quickly cleaned, thereby significantly improving cleaning efficiency, shortening downtime, and allowing for thorough cleaning of the drying chamber without dead corners, reducing cross-contamination, thus lowering the risk of material residue, ensuring product quality, extending equipment life, and reducing maintenance costs.
[0016] By setting up a placement slot, a rotating rod, and a sliding plate, the outer shell can be moved easily. When the inner tub needs to be cleaned, the outer shell must be opened first. When the outer shell is opened, the friction of the outer shell during movement can be reduced by the combined use of the placement slot, rotating rod, and sliding plate, thereby avoiding jamming of the outer shell during movement and thus avoiding affecting the cleaning efficiency of the inner tub.
