Problems solved by technology

[0003] When the grate cooler is working, the push rod is driven by the hydraulic system to reciprocate back and forth. The push rod is subject to the gravity action of the discrete cement particles, the sliding friction force, and the resistance of the movement between the mechanical equipment components. During this process, the particles There are also relative tumbling and stirring between them. These factors make the force on the push rod extremely complicated. It is impossible to accurately calculate the thrust required for the push rod to operate by traditional means. It is difficult to select the hydraulic system of the grate cooler. Therefore, , to propose a calculation method for the selection of the hydraulic system of the push rod grate cooler, which has become the basic appeal of those skilled in the art

Embodiment Construction

[0025] The present invention can be explained in detail through the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0026] The calculation method for the selection of the hydraulic system of the push rod grate cooler, the specific operation steps are as follows:

[0027] (1) Use the size specifications of the actual grate cooler to make a calculation model, and use the particle simulation software EDEM to calculate the above model. When the pusher rod moves forward, the total force received is N q N. The calculation model contains a total of n m root movable rods, the force N on each movable rod 单 for:

[0028]

[0029] (2), the length of the push rod in the calculation model is L m mm, the length of the pusher rods used in the actual grate cooler is Lmm, assuming that the thrust is evenly distributed on the pusher rods, according to the principle of equal rati...

Abstract

The invention discloses a calculation method for selection of a pushing bar type grate cooler hydraulic system, and relates to a calculation method for selection of a hydraulic system. According to the method, the selection of the pushing bar type grate cooler hydraulic system is performed by utilizing a formula defined in the specification; a process of the pushing bar type grate cooler hydraulic system is subjected to analog computation in combination with a grate cooler computation model by adopting particle analog simulation software EDEM as means, and the corresponding grate cooler hydraulic system is selected in combination with an analog result, so that the problem that complex stress analysis and equation solving need to be carried out during manual computation is avoided, a pressure parameter for configuring a hydraulic station for a grate cooler can be quickly and accurately given out, and efficient operation of the grate cooler is effectively ensured.

Description

【Technical field】 [0001] The invention relates to a calculation method for type selection of a hydraulic system, in particular to a calculation method for type selection of a hydraulic system of a pusher bar type grate cooler. 【Background technique】 [0002] As we all know, the grate cooler is one of the three major hosts of the cement firing system, which undertakes the cooling of the high-heat clinker and the recovery and utilization of excess heat. It is an important equipment to improve the quality of cement and reduce the energy consumption of the entire production line; The hydraulic system of the grate cooler is responsible for providing power for the entire equipment, which plays an important role in ensuring the normal operation of the grate cooler; configuring a suitable hydraulic station system for the grate cooler can not only ensure the efficient work of the equipment, but also reduce The comprehensive energy consumption of the system; therefore, how to accurate...
