Shandong Dongtai specializes in the production of wear-resistant guide troughs, belt guide troughs, and double-sealed average guide troughs.

Around July 1, an unexplained explosion occurred in Hongguyuan Commercial Community, Nansha Town, Yuanyang County. The explosion caused varying degrees of damage to nearby shops, residences and glass. The explosion killed a total of people and injured others to varying degrees.
Technical requirements for modification of guide trough
Main technical requirements:
The guide trough adopts flange connection method to reduce welding operations as much as possible to facilitate future equipment maintenance
Guide material The anti-overflow skirt used in the trough must have a good sealing effect, and there should be no air leakage or material leakage at the edge of the trough. The anti-overflow skirt can have a service life under on-site working conditions (mainly refers to #belts and cloth machine belts on-site working conditions, the same below) It can reach months, and it is easy to install and disassemble
The modified guide trough needs to be installed with a matching high-quality buffer bed. The buffer bed slides must be wear-resistant and durable, with a service life of more than one year under on-site working conditions, and can be effectively Reduce the impact of materials on the belt
The height of the modified guide trough should not be less than 100 meters, and a pressure reducing device should be installed inside to reduce the wind pressure inside the guide trough. A tail-end sealing box should be added to buffer the swirling flow at the dropping point. The positive pressure formed controls the dust inside the guide trough and settles on the conveyor belt
External wear-resistant plates are installed on both sides of the guide trough, which are connected by bolts and have an adjustable height function. The material is imported High chromium plate, the thickness is not less than 20 years, and the service life is not less than 20 years.
A dust suppression air curtain is installed inside the guide trough. The dust suppression air curtain is reasonably designed and can effectively suppress and reduce dust. At the same time, Both ends of the guide trough are equipped with end curtains to cooperate with the seal
&#The belt guide trough of the belt and cloth machine is equipped with an internal coal plate to adjust the dropping point of the coal chute and reduce the impact of falling coal on the anti-overflow skirt and belt The specific requirements are determined by the user based on the actual situation on site, and the construction unit implements them unconditionally
The guide trough needs to be equipped with a high-sealing observation door to ensure sealing and effectively control dust spillage. The observation door adopts a push-type door lock. It is flexible to open and facilitates on-site maintenance and inspection. The # belt and cloth machine belt are each equipped with an observation door, and the # belt is equipped with an observation door. The installation location is determined by the user according to the actual situation on site.
The guide trough body and wear-resistant plate are made using laser cutting technology to ensure the accuracy of the connection holes to facilitate daily maintenance, disassembly and installation
The overall appearance of the guide trough is smooth and has no deformation. Spray it into a standard color according to the requirements of the user. The surface paint needs to be specially treated to ensure that no paint peeling occurs every year
The guide trough must ensure the smoothness of the coal transportation and will not be wet coal or other impurities All welding areas of the guide trough must be cleaned before welding. The main fillet welds should be completed using automatic or semi-automatic welding methods to ensure sufficient penetration and no welding defects such as slag inclusions, pores, and cracks should occur. The weld groove and outer dimensions should comply with the regulations of B, B, B
According to the actual situation on site, the construction unit must unconditionally implement the special requirements put forward by the user
After the guide trough is modified, the construction unit It is necessary to leave a copy of each part's guide trough installation drawings, technical texts, electronic versions of spare parts details and cardboard with the user unit for technical archiving, and provide a set of tools required for daily inspection and maintenance
Matters not yet mentioned will be implemented Relevant national industry standards and technical requirements.
After years of operation, Dongtai now has a series of guide materials that meet different specifications such as II
and
series, from bandwidth
to bandwidth
slot products. In the long-term operation and promotion of use, various guide troughs have been welcomed and praised by the majority of users, and have also accumulated rich experience for our company. It is fully proved that Dongtai guide chute is safe, clean, waste-free and highly efficient. It is very in line with the environmental protection and high performance requirements of modern enterprises for equipment. If you need a feed trough, look for Yanzhou Dongtai! Welcome to call us!
