Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nitrogen-filled and gas-regulated granaries, in particular to a nitrogen-recycling device for nitrogen-filled and gas-regulated granaries. Background Art
[0002] Nitrogen gas conditioning technology mainly involves filling a certain concentration of nitrogen into a warehouse (i.e., a granary) to suffocate and kill pests in the space due to lack of oxygen, thereby achieving the purpose of killing insects. In the prior art, nitrogen is filled into each warehouse separately through a nitrogen pipe. Each time nitrogen is filled, not only the original air in the warehouse is discharged, but also a part of the nitrogen is inevitably discharged to ensure that a higher nitrogen concentration is reached in the cabin, resulting in a large amount of nitrogen waste. In view of the above technical problems, the present application proposes a new technical solution, which can send the nitrogen discharged from the previous warehouse to the next warehouse during the nitrogen filling process, thereby saving nitrogen consumption.
[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

Compared with the prior art, the air inlet pipe of each warehouse is respectively connected to the nitrogen main pipe, the air outlet pipe of each warehouse is respectively connected to a fan, and the outlet pipe of each fan is respectively connected to the air inlet pipe of the downstream warehouse, so that the upstream and downstream warehouses are connected in series in sequence, so that the excess nitrogen discharged when each warehouse is filled with nitrogen and regulated can smoothly enter the next warehouse, thereby saving nitrogen consumption and avoiding waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 This is a working principle diagram of the nitrogen filling, regulating and reusing device for warehouse provided by the utility model, in which the arrows indicate the flow direction of nitrogen. DETAILED DESCRIPTION
[0012] The utility model provides a nitrogen filling and regulating nitrogen recycling device for a warehouse. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0013] See also Figure 1 The utility model provides a nitrogen-filled, nitrogen-adjusting and nitrogen-recycling device for a warehouse. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual products. The accompanying drawings only show the structures related to the invention of this application, and some conventional structures are not specifically drawn. The terms "inlet valve", "outlet valve", "empty valve" and the like described in this article are merely different names for similar structures for the convenience of explanation, and are not intended to limit this application. The "multiple" or "several" mentioned in this article refers to an indefinite number, because the number of structures referred to is not an invention point, and therefore is not specifically limited.
[0014] A nitrogen filling and nitrogen conditioning and recycling device for a warehouse comprises a nitrogen main pipe 9 and a plurality of warehouses 1 arranged in sequence, each warehouse is provided with an air inlet pipe 11 and an air outlet pipe 12, the air inlet pipe of each warehouse is connected to the nitrogen main pipe 9, each air inlet pipe is provided with an air inlet valve (numbered 31 and 32 in the figure); the air outlet pipe of each warehouse is connected to a fan 2, and the outlet pipe 22 of each fan is connected to the downstream warehouse ( Figure 1 The inlet pipe of the fan (the warehouse on the right side is downstream), each fan outlet pipe is provided with an outlet valve (numbered 41 and 42 in the figure); each fan outlet pipe is provided with an exhaust pipe 23, and each exhaust pipe is provided with an exhaust valve (numbered 51 and 52 in the figure). The attached figure only schematically draws two warehouses and corresponding valves, fans, pipes and other structures, but the number of warehouses and related structures is determined by actual production conditions and is not limited here.
[0015] Furthermore, in the nitrogen-filling and nitrogen-conditioning recycling device for the warehouse, the air inlet pipe is arranged at the top of the warehouse, and the air outlet pipe is arranged at the bottom of the warehouse. This "upper-in and lower-out" nitrogen filling method can fully mix the nitrogen with the grain in the warehouse, and can effectively discharge the original air in the warehouse.
[0016] Furthermore, each warehouse is provided with a pressure sensor and a nitrogen concentration sensor (not shown in the figure), which facilitates the detection of the pressure and concentration of nitrogen in the warehouse during the nitrogen filling process.
[0017] Preferably, the pressure sensor and the nitrogen concentration sensor are arranged at the bottom of the warehouse.
[0018] In actual application, the inlet end of the nitrogen main pipe is connected to the nitrogen production equipment of the factory (equipment in the figure). For ease of understanding, the working principle is further explained below: when the first warehouse (the warehouse on the left in the figure) is filled with nitrogen, the air inlet valve 31, outlet valve 41 and exhaust valve 51 corresponding to the first warehouse are opened; the blower corresponding to the first warehouse is turned on, and the original air in the first warehouse is discharged from the exhaust pipe, and then the exhaust valve 51 is closed, and the exhaust valve 52 of the next warehouse is opened; when the nitrogen concentration and pressure in the first warehouse reach the expected value, the air inlet valve 31 and outlet valve 41 corresponding to the first warehouse are closed; the air inlet valve 32 and outlet valve 42 corresponding to the second warehouse are opened. This process is repeated until the nitrogen filling in the last warehouse meets the requirements.
[0019] It should be noted that the present application seeks protection for the device itself. The above steps are merely a brief description of the working principle of nitrogen filling. The specific operating steps can be optimized and improved according to actual production conditions. Therefore, the operating steps are not specifically limited here.
[0020] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
