To this end, the relevant information was consulted and it was decided to change the material of the rubber block to polyurethane. Polydecyl ester has many properties with high elasticity over the entire hardness range, good flexibility over a wide temperature range, good oil and grease resistance, and high Young's modulus compared to rubber of the same hardness. . In March 2000, polyurethane rubber blocks were installed on the side couplings of the No. 5 cement kiln double drive system for comparative tests. The result of the test was that the rubber block was cut after one month, and the polyurethane block was still in normal use.
In view of the success of the No. 5 kiln test, we also promoted the polyurethane block to the 2.6, 3, 1 cement mill coupling, the vibration of the reducer was reduced, the noise was also significantly reduced, and the operation effect was very good. This year alone reduces maintenance and spare parts costs by more than 100,000 yuan. Editing Wang Yanli's manual spiral gate improvement Ouyi Honghua Run Cement Factory, Dongguan 523990, Guangdong, China Manual spiral gate adopted a practice of 1. Remove the upper part is not good to enter or exit, or close the place, causing the missing material. Moreover, the greater the pressure of the insert plate, the tighter the contact with the lower support side, and the sealing effect is exerted. In addition, due to the absence of pressure on the upper part, the material is easily shoveled by the inserting board and moves freely.
Editor Wang Yanli inserts silo discharge port under the support of China Institute of Ceramics Environmental Protection Branch held a new technology lecture and consultation meeting on cement dust collection. The cement plant of the China Silicate Society Environmental Protection Branch and the Anzhen Building Materials Industry Association The dust new technology lecture and consultation meeting was held on June 46, 2001 in Jixi County, Anzhen Province.
At the meeting, Vice Chairman of the Tianjin Cement Design and Research Institute Wang Zujie introduced the development and prospects of the dust collection technology of Yongni Plant. The application of high-concentration electric precipitator, wet tower in cement plant, and kiln charging The design points of the dust collector are described.
Secretary Mao Zhiwei gave a lot of examples to explain the application trend of the dust collector in the cement plant.
Comrade Wang Cong of Wuhan Anhuan Institute of Atmospheric Institute introduced the application of bag low-pressure pulse bag dust collection technology in the renovation of clinker grinding system in cement plant.
Comrade Li Wei, the leader of the expert group, described the use of new technology to transform low-efficiency bag dust collectors.
The countermeasures include replacing the filter material with high gas-to-cloth ratio; more, cleaning the dust, improving the cleaning quality; increasing the filtration area, reducing the filtration wind speed; and replacing various new accessories.
Executive Director Chen Huanqi introduced the new control power supply high-frequency high-voltage power supply control object of the international electric precipitator, which is much smaller than the existing power supply, saves 80, and can adapt to the high specific resistance dust of =51012; It does not produce anti-corona, it is a promising control device.
Li Zai Shi Gaogong discussed the development and challenges of the turtle dust collector. The most active factor of electric dust removal is the plate line configuration. As long as the reasonable plate line configuration is developed and a reasonable rapping system is adopted, the selection can be reduced. Weight, improve efficiency.
For the dust collection of the Qianfa kiln, the humidification tower is used for quenching and tempering, and the nozzle with uniform atomization and long service life can be used to solve the high-efficiency dust collection of high specific resistance dust, and the desulfurization rate can reach 50.
There are only two measures to solve the high-concentration electric dust collector in foreign countries, that is, the mechanical pre-collection dust and ash hopper are smooth and airtight. We are fully capable of solving it. Do not introduce introduction and re-introduction, and pay attention to the invention and creation of technology.
The current international hotspots related to electric precipitators are switching power supplies; airflow distribution. The upper part of the distribution plate has a high flow point of 1; it solves the rapping of the secondary dust;
The representatives also conducted discussions and exchanges on relevant questions. Jiao Yongdao
Crimped Square WIRE MESH: Crimped square wire mesh is a type of woven wire mesh that is characterized by its square-shaped openings. It is made by weaving wires with crimped patterns, which provides stability and strength to the mesh. Crimped square wire mesh is commonly used in industries such as mining, construction, and agriculture. It is used for applications such as screening, filtering, and separating materials of different sizes.
Woven Hardware Wire Cloth: Woven hardware wire cloth, also known as woven wire cloth or woven wire mesh, is a versatile type of metal mesh made by interweaving metal wires together. It is available in various materials, such as stainless steel, brass, and copper, and with different weave patterns, including plain weave, twill weave, and Dutch weave. Woven hardware wire cloth is used in a wide range of applications, including filtration, sieving, insect screens, ventilation panels, and decorative purposes.
Iron Square Wire Mesh: Iron square wire mesh is a type of woven wire mesh made from iron wires. It features square-shaped openings and is commonly used for applications that require strength and durability. Iron square wire mesh is often used in construction projects, as fencing material, reinforcement in concrete, and for creating partitions or enclosures. It provides security and can be coated or galvanized for enhanced corrosion resistance.
These types of wire meshes offer different properties and are suitable for various applications depending on their specific characteristics, such as the material used, weave pattern, and wire diameter. It's important to choose the appropriate type of wire mesh based on the intended purpose to ensure it meets the required specifications and performance.
