Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to a pig house ammonia removal equipment. Background Art

[0002] The nitrogen in the feces and urine of livestock and poultry houses in large-scale farms will decompose into ammonia and release into the air, which is one of the important sources of ammonia emissions in the atmosphere. Many studies have shown that ammonia is an important gas in the formation of PM2.5, which can neutralize acidic substances such as SO2 and NOx in the atmosphere to produce secondary particles such as ammonium salts, which have an important impact on the formation of haze and cause air pollution.

[0003] For a long time, the ammonia pollution problem in livestock farms has not been taken seriously, and ammonia in livestock farms is emitted in an unorganized and scattered manner. Failure to clean manure in livestock and poultry houses in a timely and incomplete manner, water leakage and insufficient ventilation are important factors in the generation of ammonia in livestock and poultry houses. Ammonia pollution in livestock and poultry houses not only affects the growth and development and production performance of livestock and poultry, but also causes diseases and epidemics, endangering the safety of livestock products. Therefore, there is an urgent need for an ammonia removal equipment that does not affect breeding. Utility Model Content

When ammonia removal operation is required, the atomizer 22 converts the hydrogen peroxide dilution with a concentration of 1% to 3% in the water tank 21 into water mist through ultrasonic technology. The water mist enters the fan 1 through the through hole 11 and is blown into the air by the fan to react with ammonia in the air and convert it into harmless, so as to reduce the ammonia concentration in the pig house; when ventilation is required, only the fan runs but the atomizer 22 and the water pump do not participate in the work, and the air flow is accelerated to achieve ventilation and exhaust, promote air circulation, and reduce the humidity problem in the pig house.

[0024] In this embodiment, the MCU main control board 34 adopts the STC51 series single-chip microcomputer; the ammonia sensor 7 is an electrochemical gas sensor with a range of 0-1000ppm, a resolution of 0.1ppm, and a sensitivity of 0.135±0.015uA / ppm; the temperature and humidity sensor 8 uses DHT11, whose temperature range is 0-50℃, and its humidity range is 20%-95%RH; the first water level sensor 23 and the second water level sensor 33 both use non-contact liquid level sensors, the sensing thickness can reach 20MM, the DC input voltage is DC 5-24V, and the liquid level accuracy is ±1.5mm; the atomizer 22 uses a single-head ultrasonic atomization head fog maker, driven by DC 24V; the display screen 6 uses Guangzhou Dacai 8.0-inch non-touch screen; the water pump 31 is driven by 24V DC power supply, but not limited to this, and technicians in this field can adjust the model according to the actual situation.

[0025] In a pig house ammonia removal device in one embodiment, the driving device includes a tracking camera 41, an ultrasonic ranging module 42, a driving wheel 43 and a driving motor 44 arranged at the bottom of the chassis 3, the output end of the driving motor 44 is connected to the driving wheel 43, and the driving motor 44, the tracking camera 41, and the ultrasonic ranging module 42 are respectively connected to the MCU main control board 34. In this embodiment, the driving motor 44 adopts a 24V integrated low-voltage DC driving motor 44; the tracking camera 41 adopts a TSL1401 linear CCD sensor module, which is a linear CCD with 128 pixels; the ultrasonic ranging module 42 adopts a measurement distance of 2cm-450cm, the ranging accuracy can reach 3mm, the working frequency is 40KHZ, and the model is HY-SRF05 five-pin, but it is not limited to this. Those skilled in the art can adjust the model according to the actual situation.

[0026] In a pig house ammonia removal device in one embodiment, the chassis 3 is divided into a first space, a second space and a third space, a water pump 31 and a water storage bucket 32 ​​are arranged in the first space, a battery 35 is arranged in the second space, and an MCU main control board 34 is arranged in the third space; the cabin 2, the first space, the second space and the third space are respectively provided with an inspection door and a locking mechanism, and the opening and closing of the inspection door are controlled by the locking mechanism. The placement of multiple components in a sub-format is convenient for installation and later maintenance.

[0027] In a pig house ammonia removal device in one embodiment, the locking mechanism includes an electromagnetic lock and a button switch compatible with the electromagnetic lock. When it is necessary to open the corresponding space for internal inspection or other operations, pressing the button switch uses the electromagnetic induction principle of the electromagnetic lock to open and close the corresponding inspection door, which is simple to operate.

[0028] In an ammonia removal device for a pig house in one embodiment, a water inlet 36 connected to a water storage barrel 32 is provided on the chassis 3 .

[0029] In a pig house ammonia removal device in one embodiment, the fan 1 is tilted to spray water mist at a higher angle, ensuring that the water mist can stay in the air for a longer time and react with ammonia for a longer time. A gauze 12 is provided at the end of the fan 1 to prevent other debris from entering the fan 1.

[0030] Operation process:

[0031] Press the start button 5, the camera 9 and the drive motor 44 will start at the moment of power-on. The MCU main control board 34 in the ammonia removal equipment uses the data analysis of the tracking ultrasonic module and the tracking camera 41 to output action and speed instructions to the drive motor 44, and the drive wheel 43 executes the corresponding action and speed instructions output by the drive motor 44 to avoid obstacles;

[0032] During the process, the ammonia sensor 7 and the temperature and humidity sensor 8 monitor the ammonia concentration, temperature and humidity of the pig house in real time and display them through the display screen 6. When the ammonia concentration monitored is less than 5ppm and the humidity is lower than 85RH, it is in the "normal state" and displayed on the display screen 6; when the ammonia concentration is greater than 10ppm, it will enter the "ammonia removal state"; when the humidity is greater than 90RH, it will enter the "ventilation state". In the "ammonia removal state", the atomizer 22 converts the 1% to 3% hydrogen peroxide dilution in the water tank 21 into water mist through ultrasonic technology. The water mist enters the fan 1 through the through hole 11 and is blown into the air by the fan to react with the ammonia in the air, converting it into harmless, so as to reduce the ammonia concentration in the pig house; when in the "ventilation state", only the fan is running but the atomizer 22 and the water pump are not involved in the work, and the air flow is accelerated to achieve ventilation and exhaust, promote air circulation, and reduce the humidity problem in the pig house.

[0033] If during operation, when the first water level sensor 23 detects that the water level in the water tank 21 is lower than the preset water level, a signal is transmitted to the MCU main control board 34, and the MCU main control board 34 controls the water pump 31 to pump water, and the 1% to 3% hydrogen peroxide dilution in the water storage tank 32 is added to the water tank 21; when the second water level sensor 33 detects that the water level in the water storage tank 32 is lower than the preset water level, a signal is transmitted to the MCU main control board 34, and the display prompts that it has entered the "liquid shortage state" and is waiting for water supply. The water storage tank 32 can be directly replenished with a 1% to 3% hydrogen peroxide dilution through the water inlet 36 or by opening the corresponding inspection door of the first space.

[0034] If the battery 35 is low in power during operation, the voltage detection circuit of the ammonia removal device will give feedback and control it to return to the charging station along a fixed route to wait for manual charging. If charging is completed, the start key 5 is pressed to repeat the above process.

[0035] The above description is only a preferred embodiment of a pig house ammonia removal device disclosed in the utility model, and is not intended to limit the protection scope of the embodiments of this specification. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the embodiments of this specification should be included in the protection scope of the embodiments of this specification.

[0036] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device.
