Recently, pork has become the target of many netizens, and the price of pork has been rising as the number of pigs has decreased and the impact of African pigs. Although pork prices have risen, the hard work of pig farmers behind them cannot be ignored. In pig farm management, environmental changes in pig farms have a considerable impact on the growth rate and development of pigs, and the main impacts. The environmental factors for the growth of pigs include temperature and humidity, carbon dioxide concentration, ammonia concentration and light intensity. Therefore, it is an important way for many pig farms to ensure the safety of breeding and improve the quality of breeding by means of gas detection instruments such as carbon dioxide detectors . The main effect of carbon dioxide on pigs in pig farms is that the high carbon dioxide content in pig farms can cause chronic hypoxia, weak constitution and easy infection of various chronic infectious diseases. By using the carbon dioxide detector for detection, the carbon dioxide concentration in the pig house can be visually checked and grasped, and measures are taken in time according to the requirements of scientific production to ensure the environmental comfort during the pig breeding process. The application of carbon dioxide detectors in pig farms helps to reduce the risk of breeding, improve the quality of farming, and increase the income of pig farms. Raising pigs is a highly risky aquaculture industry. An African piglet not only causes farmers to lose money but also loses confidence. However, this disease has also made the majority of farmers understand the importance of scientific farming. In the production management of pig farms, relying on experience farming is no longer reliable. The safe way is to use modern technology to manage the production process, for example Carbon dioxide detectors measure the environmental factors of pig breeding in real time, increase the frequency of monitoring, early detection of risks to avoid losses, and use the African swine fever detector to enhance the detection of African swine fever virus. There are no special requirements for the laboratory, and non-professionals can easily get started. It is an effective way for enterprises to prevent disease threats and reduce farm losses.
This is A4 Paper Making Machine,writing and printing Paper Making Machine.
According to the different paper grade and working speed, this kind of Paper Machine is needed to select the way of papermaking, dewatering structure of press section, dryer cylinder bank, sizing and finishing equipments.
Sheet forming can use the open-type headbox, air-cushion headbox, and hydraulic headbox, gap former and inclined wire former. According to the paper uniformity requirement, it can use distributor roll or finishing surface roll.
Press dewatering type is multi-roll and multi-press nip press rather than large-diameter press. As the low basis weight and wet strength of this kind of paper, it usually makes the low strength wet sheet attached to the felt or guide rolls during each section mutual transferring and full web leading as much as possible.
Dryer section: dryer cylinder group. Paper leading: active or passive paper rope system. Finishing equipment: To choose according to the paper grade requirement.
Now we introduce the technical proposal and structural drawing of Fourdrinier advanced printing paper machine, which we made for Taiqian Minrui Huatong Paper Company in Henan province, China. The advanced printing paper of this company is the famous brand in China.
Trimmed width: 2640mm
Working speed: 400m/min
Basis weight: 50-100g/sq.m.
Headbox: Air-cushion headbox
Forming table length: 15m
Suction flat box with all stainless steel micro-crystal cover.
Press section: four rolls two press nips
The wet sheet is stripped by pick-up suction unit.
The second under press nip rubber blind bottom roll diameter is Φ800mm, with drive unit;
The suction top roll diameter is Φ800mm, with drive unit.
The top press nip is made by a stone roll and a rubber roll. The rubber roll diameter isΦ800mm, with drive unit;
The stone roll diameter is Φ850mm, with cut squirt.
This structure ensures the low strength wet sheet can press smoothly and paper breaks can be reduced.
The smooth press rubber bottom roll diameter is Φ800mm; the top stone roll diameter isΦ850mm. The paper leading roll has the drive unit.
The dryer section has 32 dryer cylinders with the diameter of Φ1800mm, which is divided into five groups: three groups for before-sizing, two groups for after-sizing. The top and bottom felt of first group and the group at the back of sizing machine is equipped with six felt drying cylinder with the diameter of Φ1250mm, which can dry the moisture well and improve the drying efficiency.
The paper leading roll has the drive unit. The paper leading type is three-stage passive paper rope system.
Sizing machine: inclined type surface-sizing machine.
Calender: four roll three press nips; the number is decided by the demands.
Reeler: horizontal pneumatic reeling machine.
