Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry, in particular to a mobile ammonia detection device for animal husbandry. Background Art

[0002] The large amount of manure produced in traditional animal husbandry can easily produce a lot of ammonia indoors in the winter when ventilation is inconvenient, or in the hot and humid summer. Ammonia is a colorless gas with a pungent and foul smell. It is lighter than air, very soluble in water, and easy to liquefy. Liquid ammonia will corrode certain plastic products, rubber and coatings. Ammonia is toxic. Inhaling a large amount of ammonia in a short period of time may cause tearing, sore throat, hoarseness, cough, blood-stained sputum, chest tightness, and difficulty breathing. It may be accompanied by dizziness, headache, nausea, vomiting, fatigue, etc. Cyanosis, conjunctival and pharyngeal congestion and edema, rapid respiratory rate, lung rales, etc. may occur. In severe cases, pulmonary edema, adult respiratory distress syndrome, laryngeal edema spasm or bronchial mucosal necrosis and shedding may occur, leading to suffocation, and may also be complicated by pneumothorax and mediastinal emphysema. Inhalation of extremely high concentrations can lead to rapid death. Although the ammonia produced in general farms is not fatal, long-term inhalation of ammonia can affect your health. At the same time, livestock will not be able to grow in a suitable environment and may even become sick and die.

[0003] In existing large-scale livestock farms, breeding pens are usually distributed in an orderly manner on both sides of the passage, and traditional fixed ammonia detection devices cannot effectively detect the ammonia conditions in each pen. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0019] An embodiment of the utility model, as Figure 1 and Figure 2 As shown, a mobile cart 1 and an air extraction mechanism and a purification mechanism arranged on the top of the mobile cart 1, the purification mechanism includes a liquid storage tank 2 installed on the mobile cart 1, at least two groups of the air extraction mechanisms are arranged and symmetrically arranged on both sides of the liquid storage tank 2, and the air extraction mechanisms are respectively provided with symmetrically installed folding arm assemblies 4 on the side away from the liquid storage tank 2. Specifically, the folding arm assembly 4 includes a lifting structure, and two sections of folding arms are movably connected on the top of the lifting structure, which expands the detection range of the first ammonia detector 41 and can avoid obstacles during movement. The end of the folding arm assembly 4 is provided with a first ammonia detector The measuring instrument 41, the exhaust mechanism includes a bellows 3 installed on the mobile trolley 1, and an air intake pipe 31 connected to the bottom of the liquid storage tank 2 is arranged on the side of the bellows 3 close to the liquid storage tank 2. The air intake pipe 31 is connected to the first air pump 32, and an extended exhaust pipe 33 is connected to the outer side of the bellows 3. Specifically, the inner wall surfaces of the bellows 3 and the air intake pipe 31 are made of alkali-resistant materials to avoid corrosion caused by long-term use and affect the sealing performance. During the movement, the ammonia concentration in each pen in the farm is detected, and the air in the area with too high concentration is purified to ensure that the indoor ammonia level of the breeding environment is at a normal level.

[0020] A filter assembly is provided inside the liquid storage tank 2 and a sealing cover is connected to the top. A drain port 21 is provided at one end of the liquid storage tank 2 away from the vacuum mechanism. When the purified liquid 24 needs to be replaced, the valve at the drain port 21 is opened to allow the purified liquid 24 to flow out of the drain port 21. An exhaust port 22 with an opening toward the drain port 21 is provided on the top of the sealing cover. A second vacuum pump 23 is installed on the side of the exhaust port 22 close to the first vacuum pump 32, and the purified air is discharged through the exhaust port 22.

[0021] The filter assembly includes a purified liquid 24 located at the bottom of the liquid storage tank 2. Specifically, the purified liquid 24 can be saturated salt water to reduce production costs. Above the purified liquid 24, there are arranged in sequence a soda lime layer 25 and an activated carbon layer 26 installed on the inner wall of the liquid storage tank 2. The triple filtering structure improves the purification capacity of the filter assembly.

[0022] A detection cavity is formed between the top of the filter assembly and the liquid storage tank 2, and the detection cavity is connected to the second vacuum pump 23. The output end of the second vacuum pump 23 is connected to the bottom of the liquid storage tank 2 through a U-shaped connecting pipe 29, and a second ammonia detector 27 is installed at the bottom of the sealing cover.

[0023] A movably installed baffle is provided below the exhaust port 22 and the sealing cover plate, and a driving cylinder 28 connected to the baffle is provided between the exhaust port 22 and the second air pump 23. The second ammonia detector 27 is electrically connected to the second air pump 23 and the driving cylinder 28 respectively. When the second ammonia detector 27 detects that the ammonia concentration in the detection chamber exceeds the standard, it means that the ammonia is not completely purified. The air in the detection chamber is extracted by the second air pump and sent to the purified liquid 24 at the bottom of the liquid storage tank 2 for re-filtration until the ammonia concentration is lower than the threshold value. At this time, the ammonia detector 27 controls the driving cylinder 28 to move the baffle to discharge the purified air.

[0024] The first ammonia detector 41 is electrically connected to the first air pump 32 on the corresponding side. When the first ammonia detector 41 on one side detects that the ammonia concentration in the air in the corresponding compartment exceeds the standard, the first air pump 32 on the same side is started to filter and purify the air containing ammonia. The first ammonia detectors 41 on both sides can work independently or simultaneously, greatly improving the detection efficiency.

[0025] The working principle of this embodiment is as follows: the staff pushes the trolley to move to the breeding pen in the area to be tested, unfolds the folding arm assembly to detect the ammonia concentration in the air in the pen. When the ammonia concentration exceeds the threshold, the first vacuum pump on the same side of the detector is started, and the staff holds the extended vacuum tube to extract air. The air containing ammonia enters the liquid storage tank and is filtered and purified by the triple filtration structure. When the ammonia concentration is lower than the threshold, the purified air is discharged through the exhaust port.
