Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for a nitrogen generator. Background Art
[0002] A nitrogen generator is a device used to produce high-purity nitrogen. It separates nitrogen from the air by physical or chemical methods to achieve the required purity level to meet the needs of different application fields. The feeding device of the nitrogen generator is a component used to add raw materials or fillers to the equipment, usually used to supplement or replace materials such as carbon molecular sieves.
[0003] The carbon molecular sieve in the nitrogen generator is usually filled in an adsorption tank. The common way to load the carbon molecular sieve particles into the adsorption tank is manual loading. In this case, not only is the efficiency slow, but also after being loaded into the adsorption tank, it may appear too fluffy and have poor filling density. During filling, if some smaller molecular sieve particles or some powder structures are mixed in, the gaps between adjacent carbon molecular sieve particles will be completely filled, resulting in reduced gas fluidity, which is not conducive to the output of nitrogen.

DETAILED DESCRIPTION
[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] Example
[0019] like Figure 1-4As shown, a nitrogen generator feeding device proposed by the utility model includes a hopper 1 and a vibrating rod 3. The hopper 1 is fixed on a fixing frame 2. An upper end frame 5 is clamped on the upper end of the hopper 1. A mounting plate 31 is fixed in the hopper 1. A bearing plate 32 is arranged on the upper end of the mounting plate 31. The upper end of the vibrating rod 3 is fixed to the bottom of the bearing plate 32, and the bottom of the vibrating rod 3 extends out of the lower end of the hopper 1. A vibrating motor 34 is fixed on the upper end of the bearing plate 32. A rubber sleeve 33 is fixed between the bearing plate 32 and the mounting plate 31. An inner sleeve 4 is inserted in the hopper 1, and a tooth groove 4 is arranged on the inner side wall of the inner sleeve 4. 1, a guide block 51 is fixed in the upper end frame 5, and the upper end of the guide block 51 is a raised arc structure. A group of connecting rods are fixed on the periphery of the mounting plate 31 and the guide block 51, and the ends of the connecting rods are respectively fixed on the inner wall of the hopper 1 and the inner wall of the upper end frame 5. A through hole 36 is opened on the mounting plate 31 and at a position corresponding to the vibration rod 3. A protective cover 35 is fixed on the upper end of the mounting plate 31 and located on the periphery of the vibration motor 34. The vibration rod 3 passes through the through hole 36. A group of electrostatic rods 6 are installed in the hopper 1 and below the inner liner 4. The ends of the electrostatic rods 6 extend out of the hopper 1 and are fixed with a terminal head 61.
[0020] An extension plate 42 is fixed to the periphery of the upper end of the inner sleeve 4, and the bottom of the extension plate 42 is against the upper end of the hopper 1. A group of assembling rods 11 are fixed to the upper end of the hopper 1. Positioning holes 43 are opened and closed at positions corresponding to the assembling rods 11 on the extension plate 42. A group of fixing slots 52 are opened at the bottom of the upper end frame 5. The upper ends of the assembling rods 11 pass through the positioning holes 43 and are inserted into the fixing slots 52. The inner sleeve 4 is a funnel-shaped structure, and the outer wall fits the inner wall of the hopper 1.
[0021] In this embodiment, the entire device is first connected to an external power supply, and then the adsorption tank is aligned with the bottom of the hopper 1, so that the vibration rod 3 is inserted into the adsorption tank, and then a certain amount of carbon molecular sieve particles are poured into the upper end frame 5, so that they flow toward the inner wall of the hopper 1 under the guidance of the guide block 51, flow down along the inner wall of the hopper 1, and finally enter the adsorption tank. At this time, the vibration motor 34 is used to drive the vibration rod 3 to vibrate, so that the carbon molecular sieve particles loaded into the adsorption tank are more substantial. At the same time, when the carbon molecular sieve particles flow down along the inner liner 4, their fine particles will enter the tooth groove 41. Internal collection improves the uniformity of the particle size entering the adsorption tank. At the same time, before entering the adsorption tank, the particles enter between the electrostatic rods 6. The adsorption of the electrostatic rods 6 can adsorb some debris and dust fragments again, further avoiding the particles from being filled with debris or fragments. While ensuring that the material is full, it will not affect the normal gas flow. When it is necessary to clean the inner sleeve 4, just pull the upper end frame 5 out of the assembly rod 11, and then easily pull the inner sleeve 4 out of the hopper 1 to clean the debris in the tooth groove 41.
[0022] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
