Description

Technical Field

[0001] The utility model belongs to the technical field of test devices for special air conditioners in granaries, and particularly relates to a device for simulating a fumigation test of a special air conditioner in a granary. Background Art

[0002] For the safe storage of grain, relatively constant temperature and humidity conditions are required. A suitable storage environment can extend the fresh-keeping period of grain, maintain its freshness and taste, which is crucial for maintaining the nutritional value and edible quality of grain. The main function of the special air conditioner in the granary is to regulate the temperature and humidity in the granary, protect the quality and freshness of the grain, and improve the storage efficiency and economy at the same time.

[0003] In addition, to prevent the breeding of insect eggs in the grain, the fumigant aluminum phosphide needs to be placed in the granary. Aluminum phosphide reacts with water in the air to produce phosphine gas, and the phosphine gas fumigates the grain and kills the insect eggs. However, the phosphine gas will corrode the above-mentioned special air conditioner in the granary. If the anti-fumigation corrosion resistance of the special air conditioner in the granary does not meet the standard, it will not be able to effectively control the temperature and humidity in the granary, thus affecting grain safety.

[0004] However, if the special air conditioner in the granary is installed in the granary and then the anti-fumigation corrosion resistance test is carried out, the test efficiency will be greatly reduced; therefore, there is an urgent need for a device that can complete the fumigation test before the air conditioner leaves the factory.

[0034] In the following, with reference to the accompanying drawings of specific embodiments of the present invention, the exemplary solutions of the embodiments of the present invention will be clearly and completely described. Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the ordinary meaning understood by those of ordinary skill in the art.

[0035] As Figure 1 shown, in the device for simulating the fumigation test of a special air conditioner for a granary in this embodiment, a first air inlet hole 101 and a first air outlet hole 102 are formed on the front surface of the air conditioner 1. The device includes a feeding component, an air outlet pipe 3, and a measuring instrument 4. The feeding component is used for feeding fumigation drugs, and the feeding component is connected to the air conditioner 1 through the first air inlet hole 101; one end of the air outlet pipe 3 is fixed to the flange at the first air outlet hole 102 through a flange and bolts, realizing the connection between the air outlet pipe 3 and the air conditioner 1; the measuring instrument 4 is used for measuring the concentration of drug gas in the air conditioner 1, and the feeding component and the air outlet pipe 3 are both connected to the measuring instrument, so that a sealed circulation structure is formed among the feeding component, the air conditioner 1, the air outlet pipe 3, and the measuring instrument 4. The present invention can effectively simulate the circulating flow of fumigation gas in the air conditioner 1, and then test and obtain the anti-fumigation corrosion resistance of the air conditioner.

[0036] Further, the measuring instrument 4 can be fixedly installed on the top of the air conditioner 1 through bolts, provided that it does not affect the test.

[0037] Further, the above-mentioned fumigation drug is aluminum phosphide, and aluminum phosphide reacts with water in the air to generate phosphine gas, and the above-mentioned fumigation gas is phosphine gas.

[0038] As Figure 3 shown, the feeding component includes a feeding pipe 2, a support plate 204, and a medicine box 203. One end of the feeding pipe 2 is detachably installed at the first air inlet hole 101 of the air conditioner 1 through a flange. The support plate 204 is horizontally welded to the inner side wall of the feeding pipe 2, and the medicine box 203 is buckled to the support plate 204 through a buckle, and the medicine box 203 is used for storing fumigation drugs.

[0039] As Figure 1 shown, the other end of the feeding pipe 2 is detachably installed with a first sealing plate 201 through a fastener, and a first through hole 202 is formed on the first sealing plate 201.

[0040] Further, the above-mentioned fastener is a quick-pressure bolt 2011, and the number of the quick-pressure bolts 2011 is four, and they are evenly distributed around the first sealing plate 201.

[0041] Further, a rubber ring is provided between the first sealing plate 201 and the feeding pipe 2 to further improve the sealing performance between the first sealing plate 201 and the feeding pipe 2.

[0042] As Figure 3As shown, the feeding assembly further includes a feeding pipe 205 vertically and integrally welded to the top wall of the feeding tube 2; a sealing cover 2051 is screwed to the feeding port of the feeding pipe 205, and the discharging port of the feeding pipe 205 is located directly above the medicine box 203.

[0043] It should be understood that the fumigation drug aluminum phosphide can be put into the medicine box 203 along the feeding pipe 205.

[0044] When necessary, to accelerate the release of the fumigation gas phosphine from the fumigation drug aluminum phosphide, a small amount of water can be put into the medicine box 203.

[0045] As Figure 1 shown, the other end of the air outlet pipe 3 is detachably provided with a second sealing plate 301 through a fastener, and a second through hole 302 is formed in the second sealing plate 301.

[0046] Similar to the first sealing plate 201, the fasteners used for the second sealing plate 301 are also four quick-pressure bolts 2011, and the quick-pressure bolts 2011 are evenly distributed around the second sealing plate 301.

[0047] Furthermore, a rubber ring is provided between the second sealing plate 301 and the air outlet pipe 3 to further improve the sealing performance between the second sealing plate 301 and the air outlet pipe 3.

[0048] As Figure 1 shown, both the first sealing plate 201 and the second sealing plate 301 are made of transparent materials, such as glass plates or acrylic plates. During the actual test process, the operator can observe the internal structure of the device and the air conditioner 1 without opening the sealing plate; at the same time, it also avoids the operator's contact with the fumigation gas phosphine and improves the safety of the test process.

[0049] As Figure 1 shown, second air inlet holes 402 and second air outlet holes 401 are respectively formed on both side surfaces of the measuring instrument. Among them, the second air outlet hole 401 is connected to the first through hole 202 of the feeding tube 2 through a connecting tube, and the second air inlet hole 402 is also connected to the second through hole 302 of the air outlet pipe 301 through a connecting tube, so as to realize the orderly connection among the feeding assembly, the air conditioner 1, the air outlet pipe 3 and the measuring instrument 4.

[0050] As Figure 1 shown, a control switch and a display screen are also installed on the measuring instrument 4. The control switch is used to control the start and stop of the measuring instrument 4, and the display screen is used to display the concentration of the fumigation gas in the air conditioner 1 in real time.

[0051] Furthermore, a circulation pump is installed in the measuring instrument 4, and the circulation pump is used to drive the fumigation gas to circulate more stably among the feeding tube 2 of the feeding assembly, the air outlet pipe 3, the measuring instrument 4 and the inner cavity of the air conditioner 1.

[0052] Specifically, the circulation pump sucks the gas in the inner cavity of the air conditioner 1 into the measuring instrument 4 along the air outlet pipe 3 to detect the concentration of the fumigation gas in the air conditioner 1, and at the same time drives the circulation of the fumigation gas along the feed pipe 2, the inner cavity of the air conditioner 1, the air outlet pipe 3 and the measuring instrument 4.

[0053] Furthermore, a partition plate 103 is welded in the middle of the air conditioner 1 to separate the air conditioner 1 into upper and lower parts, and the first air inlet 101 and the first air outlet hole 102 are both opened in the upper half of the air conditioner 1; the feed pipe 2, the air outlet pipe 3, the measuring instrument 4 and the upper half of the air conditioner 1 in the present utility model form a sealed structure.

[0054] It should be understood that during the test process, the fumigation gas phosphine will only circulate in this device and the upper half of the air conditioner 1, that is, the fumigation gas phosphine will only corrode the components (such as: core components such as the blower, evaporator and pipeline, etc.) in the upper half of the air conditioner 1.

[0055] The working principle is as follows:

[0056] S1. After assembling the feeding assembly, install it at the first air inlet hole 101 of the air conditioner 1; install the air outlet pipe 3 at the first air outlet hole 102 of the air conditioner 1; install the measuring instrument 4 on the top of the air conditioner 1;

[0057] S2. As Figure 1 shown, connect the feed pipe 2, the measuring instrument 4 and the air outlet pipe 3 in sequence with a connecting pipe, so that the feed pipe 2, the inner cavity of the air conditioner 1, the air outlet pipe 3 and the measuring instrument 4 form a circulation loop;

[0058] S3. Open the sealing cover 2051, put a small amount of fumigation drug into the medicine box 203 along the feeding pipe 205, and close the sealing cover 2051; at this time, the fumigation drug begins to react with the water in the air to release the fumigation gas;

[0059] S4. Turn on the control switch, the measuring instrument 4 (and the circulation pump inside it) works, and the fumigation gas begins to circulate along the feed pipe 2, the inner cavity of the air conditioner 1, the air outlet pipe 3 and the measuring instrument 4. At the same time, the measuring instrument 4 measures the concentration of the fumigation gas in the air conditioner 1 in real time and displays it on the display screen;

[0060] S5. After the concentration reading of the fumigation gas on the display screen is stable, if the concentration is less than the concentration of the fumigation gas specified in the grain storage specification, it is necessary to gradually put the fumigation drug into the medicine box 203 until the concentration value of the fumigation gas on the display screen is not less than the concentration of the fumigation gas specified in the grain storage specification;

[0061] S6. When the fumigation test reaches the predetermined time, remove the feeding assembly and the air outlet pipe 3 from the air conditioner 1, and observe whether there is obvious corrosion and damage of the components inside the air conditioner 1 by the fumigation gas; then connect the air conditioner 1 to an external power supply and observe whether the air conditioner 1 can work normally;

[0062]

[0062] If there is no obvious damage to the components inside the air conditioner 1 and the air conditioner 1 can operate normally, then the fumigation corrosion resistance of the air conditioner 1 meets the standard; otherwise, the fumigation corrosion resistance of the air conditioner 1 does not meet the standard.

[0063]

[0063] It should be noted that during the fumigation test, when the concentration reading of the fumigation gas on the display screen decreases, it is necessary to replenish the fumigation drug into the medicine box 203 again to keep the concentration of the fumigation gas inside the air conditioner 1 not lower than the concentration of the fumigation gas specified in the grain storage specification.

[0064]

[0064] It should be noted that when there is a description of "connected", "coupled" or "linked" between one element and another element, it may mean that they are directly connected, coupled or linked, but it should be understood that there may be intermediate elements between the two; that is, it covers the positional relationship of direct connection and indirect connection.

[0065]

[0065] It should be noted that the use of similar words such as "a" or "an" does not necessarily indicate a quantity limitation. Similar words such as "comprising" or "including" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects.

[0066]

[0066] It should be noted that terms indicating orientation or positional relationship such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships. They are for the convenience of describing the present invention, rather than the device or element must have a specific orientation, be constructed and operated in a specific orientation; when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0067]

[0067] The preferred embodiments for implementing the present invention have been described in detail above, but it should be understood that the functions of these embodiments are only for examples and do not limit the scope, application or construction of the present invention in any way. The protection scope of the present invention is defined by the appended claims and their equivalents.
