Description
Technical Field
The invention relates to a detachable die forging chain for a scraper slag dragging machine, which can be widely applied to the conveying process of ash materials of a coal-fired boiler.
Background
The materials in the scraper slag dragging machine are a mixture of water and ash, the conveying working condition is bad, ash water easily enters into a revolute pair of a chain to cause abrasive wear, and the installed capacity of a boiler is larger and larger along with the economic development of China, so that the output of the slag dragging machine is larger and larger; in order to realize environmental protection and economic production, the existing round-link chain cannot meet the requirements, and has the following main defects:
(1) There is a great deal of contamination in manufacturing and use. The chain ring is formed by welding, and the welding can cause environmental pollution. When the chain is used, the chain is cut according to the required length, a certain chain ring is required to be replaced when the equipment runs, and the chain is usually removed in a gas cutting destructive manner, so that the environment is polluted.
(2) The chain links are in line contact, so that the service life is short and the precision is low. According to the structural characteristics and manufacturing process of the round-link chain, the chain links form line contact, and when the same acting force is applied, the chain link contact surface is small, the stress is large, and the chain links are easy to wear. In double-chain transmission, uneven wear of chains at two sides can lead to asynchronous and unequal lengths of double chains, and damage of a conveying carrier or a guide wheel is caused, which is a common problem of double-round-link chain conveying. The manufacturing of the chain ring adopts low welding forming precision, and further aggravates abrasion and unequal lengths.
(3) Waste is generated. The chain length is produced according to the standard, and the cutting is reduced or the chain length is increased when in use, so that not only is the waste caused, but also the chain connecting ring is required to be added.
(4) The cost is high. The price of one chain link is about two meters of chain price; the customer, in addition to purchasing the chain, also requires additional costs of the chain links, with higher costs of imported chains. Wear resistance is one of the main performance indexes of the chain, and the service life of the chain is low based on line contact, so that the average maintenance cost is higher.
(5) And the overhaul and maintenance are difficult. When a certain chain ring is in problem, the chain ring is generally removed in a gas cutting destructive way, so that not only is the overhaul and maintenance difficult, but also the time is long, and an overhaul tool is required to be prepared, and the safety protection of flammable and explosive gas is required to be arranged.
