Description

Technical Field

[0001] This utility model belongs to the field of industrial purification technology and relates to mechanical manufacturing, specifically a cylindrical purification unit. Background Technology

[0002] Currently available air purification units mainly consist of a shell and purification materials. While they offer some air handling capacity, their reliability is limited to varying degrees due to manufacturing limitations. Specifically: One method for sealing the air duct of a cylindrical air purification unit involves mechanically pressing a sponge sheet to the outer shell. This method requires high precision in pressing uniformity and a precise fit between the purification unit and the outer shell, making it prone to localized leaks during mass production. Another method seals the air inlet end with the outer shell, while the flow-blocking end is sealed with a tray using a single-piece glue-filled sealant. This structure is highly susceptible to misalignment of the gaskets, tray deformation, and sealant cracking after exposure to harsh transportation and usage conditions such as vibration, drops, and extreme temperatures, leading to airflow short circuits. Furthermore, this method involves internal glue filling during manufacturing, making it difficult to effectively inspect the glue quality. Finally, cylindrical air purification units are typically installed using vertical mechanical pressing and horizontal limiting methods. To ensure ease of assembly during manufacturing, these limiting methods often have significant allowances, resulting in unreliable upper and lower limit positions. Summary of the Invention

[0003] The purpose of this utility model is to provide a cylindrical purification unit that solves the problems of poor manufacturing and installation process and the risk of airflow short circuit in existing purification units. It features easy installation, reliable use, improved product quality, and easy application and promotion.

[0004] This utility model is achieved using the following technical solution:

[0005] A cylindrical purification unit includes an annular top cover, purification material, an inner porous cylinder, an outer porous cylinder, a blind cover, and an annular bottom cover.

[0006] The inner porous cylinder is located inside the outer porous cylinder, and the annular top cover is fixedly connected to the top of the inner porous cylinder and the top of the outer porous cylinder; the purification material is filled in the annular interlayer space between the inner porous cylinder and the outer porous cylinder; the annular bottom cover is fixedly connected to the bottom of the inner porous cylinder and the bottom of the outer porous cylinder; the blind cover is fixedly installed in the inner hole of the annular bottom cover.

[0007] More preferably, the inner ring edge I of the annular top cover is welded and fixed to the top end of the inner porous cylinder, and the outer ring edge I of the annular top cover is welded and fixed to the top end of the outer porous cylinder.

[0008] More preferably, a rubber pad is placed inside the annular cavity of the annular bottom cover.

[0009] More preferably, the inner edge of the inner ring side II of the annular bottom cover is provided with multiple threaded holes, and the blind cover is fixed in the inner hole of the annular bottom cover by screwing a bolt through the through hole on it into the corresponding threaded hole.

[0010] More preferably, the inner ring edge II and the outer ring edge of the annular bottom cover are fixedly connected to the bottom end of the inner porous cylinder and the bottom end of the outer porous cylinder by rivets, respectively.

[0011] More preferably, a sealant layer is injected into the inner hole of the annular bottom cover.

[0012] More preferably, the outer surface of the annular top cover is provided with an embedded threaded hole that connects to the air inlet passage.

[0013] More preferably, the outer surface of the annular top cover is provided with two inner and outer rings of embedded threaded holes.

[0014] More preferably, the inner edge of the inner ring side II of the annular bottom cover is provided with three threaded holes, and the edge of the blind cover is also provided with three through holes accordingly.

[0015] More preferably, the inner hole of the annular bottom cover is matched and limited by the external mounting boss.

[0016] During installation, the outer perforated cylinder is fitted over the inner perforated cylinder, and then the annular top cover is fixed to the upper end of both cylinders, thus assembling the main frame. The purification material is poured between the inner and outer perforated cylinders from their lower ends. The rubber gasket is then accurately embedded into the annular cavity of the bottom annular cover. The bottom annular cover with the gasket installed is aligned with the bottoms of the inner and outer perforated cylinders. The inner and outer ring edges of the bottom annular cover are fixed to the bottom ends of the inner and outer perforated cylinders respectively using rivets. The blind cover is then fixed in place within the inner hole of the bottom annular cover by screwing through the through holes into the corresponding threaded holes. Finally, a sealant layer is applied to all welded joints, bolted connections, and rivet fixing interfaces. A continuous sealing ring is formed around the bolt heads, nuts, and washers at the bolted connections.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. In this utility model, the annular top cover can achieve air passage sealing and fixation at the air inlet end by pre-reserved embedded threaded holes and fastener installation.

[0019] 2. In this utility model, threaded holes can be machined on the inner side of the annular bottom cover, and glue can be poured on the outer side after the blind cover is installed by fasteners. The quality of glue bonding can be checked, which effectively avoids the possibility of leakage.

[0020] 3. In this utility model, the annular bottom cover itself is concave, which can cooperate with the external mounting boss for positioning, and can be reliably fixed by combining with the fastener installation of the annular top.

[0021] The purification unit of this utility model has a reasonable overall structural design. The air inlet is fixed and sealed with bolts through a pre-reserved threaded hole in the annular top cover. The flow-blocking end is sealed with glue after a blind cover is installed to the annular bottom cover using fasteners. The inner hole of the annular bottom cover cooperates with the external mounting boss for limiting movement. It is not limited by changes in size or the position and number of mounting threaded holes, and has good practical application value. Attached Figure Description
