Describle:
PP plastic filters is developed and designed for chemical industry. It is an excellent economic and practical anticorrosive filter which is widely used in solid-liquid separation of corrosive materials of acid and alkali. The whole plastic cylinder and its accessories are made of pvdf, pph, ppr and other anticorrosive plastic materials to realize the contact between non-metal parts and materials, which can be competent for high temperature, high concentration hydrochloric acid, sulfuric acid, etc. aqua regia and other strong acid strong base liquid filtration and most of the chemical liquid filtration. The filters are fast open, easy to maintain, easy to disassemble. The bottom of the cylinder is designed with a clever slope, no residual fluid after filtration. The integral molding injection molding process makes the cylinder without any soldering interface and solder joint, and the inner surface is smooth without dead angle. The plastic anticorrosive filter is widely used in chemical industry.
1.The Filter Material inlet adopts the jacking tortoise shell design, the liquid flow is more unobstructed and the liquid accumulation.
2. Top cover adopts the quick opening way, the maintenance is convenient and easy to disassemble, and it is equipped with 6 sus316 flange bolt rings to protect the pressure.
3. The bottom of the sealing filter adopts slope design, no residual liquid after filtering, to avoid material waste .
4. The barrel body ,basket, and the filter bag ring is made of high temperature modified polypropylene (ppr/pph) or pvdf anticorrosive material.
5. The cylinder body has no welding interface and weld, and the smooth and beautiful.
6. The sealing ring is made of fluorine rubber material. Excellent corrosion resistance.
7. The flange bolt hole spacing of inlet and outlet has multi-functions, which can be matched with national standard, American standard, day standard, German standard flange.
8. The mounting square base to enhance the safety and stability of the filter, easy to be fixed in different demand situations .

[China Agricultural Machinery Industry News] The straw of farmland crops is actually not a problem. With the high yield, the amount of straw is large. And because the countryside also uses a variety of fossil fuels, most of the straw is discarded. In order to cultivate in the coming year, the peasant figure is convenient and saves it. Burning straw on the spot directly in the field directly brings about the problem of smoke pollution. In order to realize the green wish of “zero incineration†and straw returning to the field, all localities have made surprises.
When the straw is burned in the wheat harvesting season?
Straw can also become a craft
Walking into Dongguan Village, Chengguan Town, Qingfeng County, we will see that many women use the straw after the wheat harvest to make long “scorpionsâ€, and they gather together in groups of three and five. Using straw straw hats and cushions has become a new way to make money in the village. These handicrafts were purchased by straw processors and exported to foreign countries.
According to the villagers, these wheat straws were harvested by hand with a sickle, and then the wheat straw with moderate thickness and white color was pre-selected, the wheat ears were cut off, and placed in a dry place for later use. In your spare time, take out the straw and fold the roots. Leave only the stem section and remove the leaf sheath. You can use it.
This hand-made straw scorpion is meticulously compact, practical and beautiful, and is popular among straw-wrapped merchants. Whenever the wheat harvest season, many villagers in Qingfeng County were looking for straw and braided seeds, which not only effectively banned the straw, but also increased the income of the villagers.
Straw bidding farewell to waste can also become a treasure
The comprehensive utilization of crop straw is an important measure to protect the ecological environment, improve fertility, increase farmers' income, increase the comprehensive production capacity of grain, and promote the sustainable development of agriculture.
Shaanxi Province can be said to be a province with high comprehensive utilization of straw. The provincial government has spent 20 million yuan each year as a special fund for comprehensive utilization of straw, mainly used for demonstration field construction, construction of straw mechanized comprehensive utilization cooperatives, introduction of new technology and new equipment, and demonstration publicity. Training, demonstration of the field through the operation of subsidies and other forms, to achieve a comprehensive utilization rate of straw mechanization 100%. Since 2013, the province has adjusted the agricultural machinery subsidy policy, and implemented open subsidies for straw comprehensive utilization machinery such as straw crushing and returning machine, straw forage processing machinery, straw picking and baling machine, and further activated the farmers' purchase of straw comprehensive utilization machinery. enthusiasm.
Agricultural machinery helps straw ban
During the "Three Summers" period, the provincial and municipal agricultural machinery offices will supervise the districts and counties to actively deploy equipment, vigorously organize the implementation of wheat straw smashing and returning to the field, to ensure that the summer grain harvests one mu, the straw comprehensive utilization of one mu, the autumn grain sowing one acre, not the straw Burning leaves time and space.
All localities actively promoted the popularization and application of wheat combined machine harvesting and straw crushing and returning technology. For the wheat harvesting machinery that was not installed and newly purchased this year, all the straw shredded and returning machinery were installed, and the harvesting machinery without the shredded returning machine was prohibited. Homework. Organize agricultural machinery supervisors and technicians to go deep into the field, train operators on site, freely overhaul and harvest harvesting machinery, reduce the height of the header, and control the height of stubble below 12 cm to reduce the chance of burning due to excessive inconvenience of straw. . Actively carry out wheat combined harvesting - straw smashing to cover the surface - corn machinery live "one-stop" operation, reduce the operation link, improve the level of mechanization of corn planting, speed up the progress of the three summer harvest, greatly reduce the adverse impact of rainy weather on the production of Sanxia agricultural machinery.
