Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphite powder recycling technology, specifically a dust-proof graphite powder recycling mechanism. Background Technology
[0002] Graphite is a crystalline form of carbon, hexagonal in crystal system, ranging in color from iron-black to dark gray. It is soft, has a slippery feel, is electrically conductive, chemically inert, corrosion-resistant, and does not readily react with acids or alkalis. When heated strongly in air or oxygen, it can burn to produce carbon dioxide. Strong oxidizing agents will oxidize it into organic acids. It is used as an anti-friction agent and lubricant, and in the manufacture of crucibles, electrodes, dry cell batteries, and pencil leads. High-purity graphite can be used as a neutron moderator in nuclear reactors. However, when graphite is processed by drilling, grinding, or grooving, a large amount of graphite debris is generated.
[0003] Failure to collect and process graphite debris can easily lead to the waste of graphite raw materials. Existing graphite powder recycling mechanisms use filters to protect the inlet and outlet of the collection box, thereby protecting the dust collection mechanism. However, the filters are usually bolted to the surface of the collection box, which reduces their practicality when cleaning and maintenance are required. Utility Model Content
[0004] The purpose of this invention is to provide a dust-proof graphite powder recycling mechanism to solve the problem mentioned in the background art that the filter screen is generally bolted to the surface of the collection box, which reduces its practicality when the filter screen needs to be cleaned and maintained.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust-proof graphite powder recycling mechanism, comprising an installation shell, a dust collection chamber fixedly connected to its upper surface, an opening on the front surface of the installation shell, a dust collection drawer on the inner wall of the opening on the front surface of the installation shell, two limiting baffles fixedly connected to the top surface of the opening of the installation shell, a feed filter screen disposed between the two limiting baffles, two linkage plates installed on the top surface of the opening of the installation shell, a linkage slider fixedly connected to one end of each linkage plate, an electromagnetic vibrator fixedly connected to the lower side surface of each limiting baffle, an opening on the side surface of the dust collection drawer, a lateral filter screen disposed on the inner wall of the opening of the dust collection drawer, a positioning locking block embedded in the inner wall of the opening of the dust collection drawer, and an exhaust sealing mechanism disposed on the side surface of the installation shell, which uses a sealing gasket fixed to the inner wall of the exhaust opening to fit the lateral filter screen and finally uses an exhaust pipe to collect dust with an exhaust fan.
[0006] Preferably, the mounting housing is connected to the dust collection chamber, the upper surface of the dust collection drawer is provided with a groove, the rear surface of the dust collection drawer is provided with a groove, and the width of the groove of the dust collection drawer is greater than the width between the two limiting baffles.
[0007] By adopting the above technical solution, the outer casing is connected to the dust collection chamber, ensuring that the negative pressure generated by the dust collection fan can cover the entire recycling mechanism, so that graphite powder can be smoothly sucked into the dust collection drawer through the feed filter.
[0008] Preferably, the width of the feed filter screen is greater than the width of the opening on the upper surface of the mounting housing, and the upper surfaces at both ends of the feed filter screen are provided with slots, and the slots of the feed filter screen are L-shaped.
[0009] Using the above technical solution, the L-shaped slot cooperates with the L-shaped block of the linkage plate, and the filter screen can be locked or removed simply by pushing the linkage slider horizontally, without the need for tools.
[0010] Preferably, the linkage plate and the mounting housing are slidably connected, and one end of the linkage plate is provided with an L-shaped block. The block of the linkage plate penetrates the top surface of the cavity of the mounting housing, and the block of the linkage plate is engaged with the slot of the feed filter screen. The linkage slider and the mounting housing are slidably connected, and a spring is connected between the linkage slider and the mounting housing. The side surface of the linkage slider is arc-shaped.
[0011] By adopting the above technical solution, the spring connection ensures that the linkage slider automatically resets after being released, maintaining the locked state of the plate and the filter screen, and preventing the locking from loosening due to vibration.
[0012] Preferably, the side filter screen has a T-shaped cross-section in the vertical direction, and the outer surface of the side filter screen is provided with a groove. The positioning locking block and the dust collection drawer are slidably connected, and a spring is connected between the positioning locking block and the dust collection drawer. The positioning locking block and the side filter screen are engaged.
[0013] Using the above technical solution, the T-shaped cross section creates a stepped seal when the filter is embedded in the dust collection drawer opening. Combined with the locking block, it prevents dust from escaping from the side gaps, making it especially suitable for high-pressure dust collection scenarios.
[0014] Preferably, the exhaust sealing mechanism includes an exhaust opening, which is opened on the side surface of the mounting housing. A sealing gasket is fixedly connected to the inner wall of the exhaust opening, and an exhaust pipe is fixedly connected to the outer surface of the mounting housing.
[0015] The above technical solution guides the filtered air out through the exhaust opening, avoiding turbulent airflow that could cause dust to re-entrain. The sealing gasket fits snugly against the side filter screen to prevent dust leakage during exhaust.
[0016] Preferably, the exhaust opening is funnel-shaped, and the width of the exhaust opening is greater than the width of the side filter screen; the sealing gasket is annular; and the exhaust opening and the suction pipe are concentrically arranged.
[0017] The above technical solution ensures that the annular sealing gasket fits perfectly with the filter screen, and the concentric design ensures uniform force during air extraction, avoiding localized air leakage; it is also compatible with side filters of different sizes.
[0018] Compared with the prior art, the beneficial effects of this utility model are: the dust-proof graphite powder recycling mechanism:
[0019] 1. The feed filter intercepts large particles of powder, while the side filter filters fine dust, forming a multi-level dust barrier. The bucket-shaped design of the exhaust port guides the airflow to slow down and uses inertia to make the dust settle, reducing the load on the filter and extending the cleaning cycle. The housing is connected to the dust collection chamber and is connected to the exhaust fan through the air extraction pipe to form a negative pressure environment throughout the entire path, ensuring that graphite powder is quickly sucked into the dust collection drawer and preventing accumulation and overflow.
[0020] 2. The feed filter screen engages with the linkage plate via an L-shaped slot. Pressing the linkage slider unlocks and removes the filter screen. The side filter screen is fixed by a spring-driven positioning locking block. It can be manually pulled out for cleaning. The electromagnetic vibrator on the limit baffle can be activated periodically. The high-frequency vibration of the filter screen causes dust to fall into the dust collection drawer, reducing the frequency of manual cleaning. This is especially suitable for continuous processing scenarios. The groove of the dust collection drawer is embedded in the bottom of the limit baffle. After the linkage plate locks in place, a rigid seal is formed. The annular sealing gasket on the inner wall of the exhaust opening fits tightly with the side filter screen, blocking the dust leakage path in all directions.
[0021] 3. The width of the feed filter screen is larger than the opening of the mounting shell, forming an extended shield to prevent dust from escaping from the edge. The connection design between the dust collection chamber and the mounting shell ensures orderly airflow and avoids dust caused by eddies. The bucket-shaped exhaust opening guides the airflow to be discharged in a directional manner, reducing the risk of secondary dust. Attached Figure Description

Dust impacts the filter with the airflow, large particles are intercepted, and small particles pass through the filter and enter the dust collection drawer 3. The positioning locking block 10 is driven by a spring to engage with the groove on the outer surface of the side filter 9 to fix the side filter 9.
