Description

Technical Field

[0001] This utility model relates to a stirring device, and more particularly to a filtration device on a carbon molecular sieve suction pipe. Background Technology

[0002] Carbon molecules are used extensively in modern molecular production processes. Due to the uncertainty of carbon molecule particle size, they all require pretreatment, such as high-temperature precipitation.

[0003] After the carbon molecular sieve is deposited and its pores are adjusted in a high-temperature deposition furnace, it enters a cooling tank for cooling. Due to the previous process, the carbon molecular sieve will have a small amount of large particle impurities, with the size of the impurities being 20*20~40*40mm. When the carbon molecular sieve is cooled to 50℃, the negative pressure generated by the suction fan transfers the carbon molecular sieve through the suction pipe to the storage tank in the packaging workshop, where it awaits screening and packaging. The suction pipe is laid underground, and there are inevitably many bends. Large particles of material sometimes get stuck in the pipe, causing the pipe diameter to become smaller or blocked. Manual troubleshooting is often required, resulting in a decrease in overall suction efficiency and an increase in the workload of workers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a filtration device on a carbon molecular sieve suction pipe, which aims to filter out large particulate impurities at the front end of the suction pipe (cooler outlet) and prevent large particulate impurities from entering the underground suction pipe.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a filtration device on a carbon molecular sieve suction pipe, comprising an inlet end, an outlet end, and a filtration chamber; the inlet end and the outlet end are located at both ends of the filtration chamber and are fixedly connected to the filtration chamber; the filtration chamber includes a separation chamber, an inlet flare, an outlet constriction, an air hammer base, and a filter grid; the inlet flare and the outlet constriction are located at both ends of the separation chamber, with the larger diameter end connected to the separation chamber and the smaller diameter end connected to the inlet end and the outlet end respectively; the filter grid is located inside the separation chamber, close to the outlet constriction, and is fixedly connected to the separation chamber; the air hammer base is located on the upper part of the separation chamber and is fixedly connected to the separation chamber.

[0006] Furthermore, an impurity storage bin is provided below the separation chamber to hold the filtered impurities.

[0007] Furthermore, the bottom of the impurity storage bin is provided with a movable cover plate, one end of which is rotatably connected to one side of the impurity storage bin, and the other end is detachably fixedly connected to the impurity storage bin.

[0008] Furthermore, a rotating shaft is provided on one side of the bottom of the impurity storage bin, and the rotating shaft is connected to the movable cover plate.

[0009] Furthermore, a locking base plate is provided on the other side of the bottom of the impurity storage bin, which cooperates with the movable cover plate to form a detachable connection.

[0010] Furthermore, a sealing gasket is provided on the movable cover plate to seal the impurity storage bin.

[0011] Furthermore, the feed end includes a feed pipe interface and a feed sealing step; the feed pipe interface is connected to an external hose for the entry of carbon molecular raw materials; the feed sealing step is located at one end of the feed pipe interface for sealing the connected hose, and the other end is connected to the small-diameter end of the feed flare.

[0013] Compared with the prior art, the filtration device on the carbon molecular sieve suction pipe provided by this utility model filters large molecular impurities into the separation chamber through the filter grid. When the separation chamber is blocked or the flow rate is reduced, the air hammer base can be hammered at regular intervals to vibrate the separation chamber, causing the impurities to fall into the impurity storage chamber and then be removed through the movable cover plate. This reduces the need for traditional channel cleaning, while uniformly handling impurities, effectively protecting the workshop environment and improving production efficiency.

[0019] In one embodiment, an impurity storage bin 7 is provided below the separation bin 14 to hold the filtered impurities; a movable cover plate 9 is provided at the bottom of the impurity storage bin 7, one end of the movable cover plate 9 is rotatably connected to one side of the impurity storage bin 7, and the other end is detachably fixedly connected to the impurity storage bin 7; a rotating shaft 10 is provided on one side of the bottom of the impurity storage bin 7, and the rotating shaft 10 is connected to the movable cover plate 9; a locking bottom plate 11 is provided on the other side of the bottom of the impurity storage bin 7, which cooperates with the movable cover plate 9 to form a detachable connection; a sealing gasket 8 is provided on the movable cover plate 9 to seal the impurity storage bin 7.

[0020] In one embodiment, the feed end includes a feed pipe interface 1 and a feed sealing step 2; the feed pipe interface 1 is connected to an external hose for the entry of carbon molecular raw materials; the feed sealing step 2 is located at one end of the feed pipe interface 1 for sealing the connected hose, and the other end is connected to the small diameter end of the feed flare 3; the discharge end includes a discharge pipe interface 13 and a discharge sealing step 12; the discharge pipe interface 13 is connected to an external hose for the output of carbon molecular raw materials; the discharge sealing step 12 is located at one end of the discharge pipe interface 13 for sealing the connected hose, and the other end is connected to the small diameter end of the discharge constriction 6.
