Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to an exhaust device for waste gas from a nitrogen generator. Background Art

[0002] Controlled atmosphere grain storage refers to a grain storage technique that artificially alters the gas composition of the normal atmosphere or adjusts the existing gas ratio to control the gas concentration within a certain range and maintain it for a certain period of time, thereby achieving the effects of killing insects, inhibiting mold, and slowing changes in grain quality. In practical applications, high-concentration nitrogen is often used to fill granaries. With the maturity and widespread application of controlled atmosphere grain storage technology, grain depots need to construct and renovate existing granaries, which requires the installation of nitrogen generators. Original granaries are generally not designed with dedicated nitrogen generator rooms. If nitrogen generators are directly placed in other supporting rooms in the grain depot, the oxygen emissions during the nitrogen production process will cause high oxygen concentrations in the room, which will affect nitrogen production efficiency to a certain extent. Furthermore, the exhaust noise is very loud, preventing operators from carrying out nitrogen filling and gas conditioning operations in a good environment, affecting their physical and mental health. Utility Model Content

[0003] The utility model aims to provide a nitrogen generator exhaust device, which has the effect of arranging the nitrogen generator exhaust device for outdoor exhaust, preventing sun exposure and rain, and generating noise during exhaust without affecting indoor workers.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: a nitrogen generator exhaust gas exhaust device includes an extension pipe, an exhaust device connected to the extension pipe, a shielding fence located on the side of the exhaust device, and a top surface located above the exhaust device, wherein the shielding fence includes a frame and a louver structure installed on the frame.

[0005] By adopting the above technical solution, the exhaust device is set outdoors, the top surface is used to block the sun and rain, and the enclosure fence can play the role of protection, ventilation and exhaust.

[0006] The present invention is further configured as follows: the number of the enclosure fences is three.

[0007] By adopting the above technical solution, three enclosure fences are combined with a wall to form a space for installing the exhaust device.

[0008] The utility model is further configured as follows: the material of the enclosure fence is aluminum alloy.

[0009] The utility model is further configured as follows: the louver structure includes a plurality of leaves, the leaves are rotatably connected to the frame, a top plate is provided above the top surface, a plurality of springs are installed between the top plate and the top surface, a vertical adjustment rod is fixed to the top plate, and an adjustment rope is connected between the leaves and the adjustment rod.

[0010] With this technical solution, when it rains, more rainwater accumulates in the top pan, causing it to descend, driving the adjustment rod downward. The adjustment rod, via the adjustment rope, rotates the blades, narrowing the gaps in the louver structure and preventing rainwater from drifting onto the exhaust system between the fences. After the rain stops, the rainwater in the top pan gradually evaporates, and the spring force causes the top pan to gradually rise, driving the adjustment rod upward. The adjustment rod, via the adjustment rope, rotates the blades, gradually widening the gaps in the louver structure and enhancing ventilation.

[0011] The utility model is further configured as follows: the spring is a plastic spring.

[0012] By adopting the above technical solution, the plastic spring will not rust.

[0013] The present invention is further configured as follows: the top surface is made of stainless steel.

[0014] The present invention is further configured as follows: the top surface is mounted and fixed on the upper end of the enclosure fence.

[0015] The beneficial effects of the utility model are as follows: the exhaust device of the nitrogen generator is installed in the outdoor enclosure, and the added top surface can prevent rain and sun, which is beneficial to protecting the exhaust device; the noise generated during exhaust will not affect the indoor staff, and at the same time the exhaust gas is discharged to the outdoors, so the air in the nitrogen generator room remains fresh, thereby improving the working environment and ensuring the physical and mental health of the staff.
