Description

Technical Field

[0001] The utility model belongs to the technical field of deliquescence devices, and in particular relates to a deliquescence device capable of relieving pressure. Background Art

[0002] At present, fumigation technology is a common technology for modern grain storage, which plays a great role in grain storage safety. Deliquescence dosing is a commonly used dosing method for fumigation operations. For example, the Chinese utility model patent with the authorization announcement number CN211581343U discloses an aluminum phosphide deliquescence device. This type of deliquescence device is relatively common. It is mainly composed of a cabinet, an air inlet, an air outlet, and a placement rack. The placement rack is located in the cabinet for placing the agent. The air inlet is connected to a moist carbon dioxide gas source. After the carbon dioxide gas enters the cabinet, it reacts with the aluminum phosphide agent on the placement rack to produce phosphine gas. After the phosphine gas and the carbon dioxide gas are mixed, they enter the warehouse through the air outlet and the subsequent air duct to kill insects. In actual applications, it is found that this type of deliquescent device requires a positive pressure carbon dioxide gas source to be delivered into the cabinet. If the entire pipeline system is poorly ventilated for a short period of time, it will cause excessive system pressure and cause pipe leakage. Although the pipe can be repaired and sealed after the pipe burst, it is difficult to find the leakage point in a short time due to the long pipeline system, and maintenance is more troublesome. Therefore, in response to the above problems, we proposed a deliquescent device with pressure relief. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-Figure 6 As shown, the deliquescent device with pressure relief of the present embodiment comprises a cabinet 1, and an air inlet 11 and an air outlet 12 are respectively arranged on the left and right sides of the cabinet 1, the air inlet 11 is at a high position, used to connect to the carbon dioxide gas source, and the air outlet 12 is at a low position, used to connect to the pipeline communicating with the warehouse, and a placement rack 13 is provided in the cabinet 1, and the placement rack 13 has a plurality of placement racks 13, and the plurality of placement racks 13 are longitudinally spaced and distributed, and the placement rack 13 is used to place medicines, and the common medicine is aluminum phosphide. A water storage container is also placed in the cabinet 1 of the present embodiment to increase the humidity in the cabinet 1.

[0027] In this embodiment, a pressure relief device 2 is provided at the rear side of the cabinet 1, which is used to relieve pressure when the air pressure in the cabinet 1 is too high, so as to protect the pipeline system where the deliquescence device is located. Specifically, the pressure relief device 2 includes a pressure relief pipe 21, a mounting seat 22, a pressure cylinder 23 and a film 24. The pressure relief pipe 21 is fixedly connected and communicated with the cabinet 1, the mounting seat 22 is fixedly connected to the cabinet 1 and corresponds to the position of the pressure relief pipe 21, the pressure cylinder 23 is threadedly connected to the mounting seat 22 and is coaxially arranged with the pressure relief pipe 21, and the film 24 is clamped between the pressure relief pipe 21 and the pressure cylinder 23 to close the pressure relief pipe 21. In the cabinet 1, the film 24 will be the weakest part. When the air pressure inside the cabinet 1 increases, the film will be impacted until the film is broken, so that the pressure can be relieved to protect the pipeline system.

[0028] After the film is damaged and the pressure is released, the pressing cylinder 23 can be twisted to the side away from the pressure relief pipe 21 to release the squeezing and fixing of the film. At this time, a new film can be installed between the pressing cylinder 23 and the pressure relief pipe 21 for protection. The specific installation operation is to flatten the film and place it between the pressing cylinder 23 and the pressure relief pipe 21, and then tighten the pressing cylinder 23 to one side of the pressure relief pipe 21, so that the film can be fixed between the pressing cylinder 23 and the pressure relief pipe 21.

[0029] Furthermore, the mounting seat 22 includes a base 221, a slide bar 222 and a top seat 223, the two ends of the slide bar 222 are respectively fixed to the base 221 and the top seat 223, the base 221 is fixed to the cabinet 1, and the pressure cylinder 23 is threadedly connected to the inner side of the top seat 223. In addition, in this embodiment, the front end of the pressure cylinder 23 is rotatably connected to a pressure ring 25 slidably connected to the slide bar 222, and the film 24 is clamped between the pressure relief pipe 21 and the pressure ring 25. When the pressure cylinder 23 is twisted, the pressure cylinder 23 will drive the pressure ring 25 to slide back and forth, and the pressure ring 25 is slidably connected to the slide bar 222, so the pressure ring 25 will not rotate, so that the film 24 can be pressed by the pressure ring 25 to avoid rotational friction of the film 24, so as to avoid the film 24 from being worn, thereby improving the success rate of fixing the film 24.

[0030] In this embodiment, the rear end of the pressure relief pipe 21 has an annular groove 211, and the front end of the pressure ring 25 has an annular protrusion 251 matching the annular groove 211. This design can produce annular extrusion on the film 24, thereby improving the sealing strength between the film 24 and the rear end of the pressure relief pipe 21.

[0031] In this embodiment, there are three slide bars 222, which are evenly distributed in a circular array around the axis of the pressing cylinder 23. This arrangement can improve the connection strength between the base 221 and the top seat 223. Among the three slide bars 222, one is located directly below the pressing cylinder 23, so that the upper space between the base 221 and the top seat 223 can be opened to facilitate the installation of a new film.

[0032] In this embodiment, the side of the base 221 has three evenly distributed mounting ears 2211, and the mounting ears 2211 are used to assemble screws and fix with the cabinet 1. In addition, the base 221 is sleeved on the outside of the pressure relief pipe 21, so that the base 221 can be fixed more stably.

[0033] In this embodiment, the rear part of the side of the pressing cylinder 23 has a plurality of anti-skid protrusions 231. The anti-skid protrusions 231 can improve the friction coefficient of the side of the pressing cylinder 23 so that the user can stably rotate the pressing cylinder 23.

[0034] In summary, the utility model discloses a deliquescence device capable of pressure relief, which has a film-type pressure relief device, which is used to relieve pressure when the air pressure in the cabinet is too high, so as to protect the pipeline system where the deliquescence device is located. In addition, after the film is damaged and the pressure is relieved, it can be replaced more conveniently, and the maintenance cost is low.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
