As mentioned above, many types of plant equipment configuration schemes are basically the arrangement between equipment units. The so-called unit is composed of several different machines capable of accomplishing certain technological tasks. The vertical and horizontal planes are close together, and the combination of materials is transported by self-flow or short distance. The feed and discharge have formed a fixed drop and distance. When configuring the device, the device moves along the vertical elevation and plane to adjust to the appropriate position. And consider the support, erection, fixation, equipment and equipment connection and non-standard parts design. The practices and considerations are roughly:
1. Determine the combination of equipment in the unit according to the process requirements. The combination includes main equipment, auxiliary equipment and non-standard equipment. A single figure that can be positioned and installed is required. According to the specific conditions and needs, the geometric shape and basic size of the non-standard device are preliminarily determined. The main features of the equipment, feeding, discharging and storage devices in the unit are shown on the drawing, and the relationship between the materials and the fixing method is determined. In the flat section view, the unit and equipment positioning dimensions of the unit, the longitudinal and lateral distances of the nearest positioning axis of the center line of the unit and the plant, the distance from the platform, the ground elevation and the tilt angle are shown.
Second, the equipment configuration in the unit must consider the rationality of the equipment and equipment fixation, support, erection, suspension, component replacement, disassembly, lifting, maintenance and operation, adjustment, maintenance, to ensure that the flow of materials in the unit is smooth, Strengthen the wet and viscous materials to pass through the funnel, flow cell and discharge port of the mine.
Third, the distance between the unit and the unit should be shortened, and the total height of the unit should not have excessive loss. Determination of the position of the unit: The unit leading the material should be first positioned, and then the horizontal and vertical distances of the center line of any equipment in the unit and the nearest positioning axis in the building are fixed. The position of the subsequent operation unit shall be determined so that the materials processed by the former unit are reasonably transported to the unit. The transportation equipment used shall work within the allowable lifting angle, head and self-flow slope, and rationally utilize the terrain to minimize the amount of earthwork. Finally, the position of the subsequent unit is fixed, and the horizontal and vertical distance dimensions of the nearest positioning axis of any equipment center line and the factory building are marked. In short, the positioning process between the units is to increase, decrease, shift left and right, and shift back and forth as a whole for each unit.
4. The equipment foundation and the column foundation should be kept at a certain distance. The equipment foundation with large body weight should be placed on the hard rock. The general equipment can be placed on the floor or I-beam, channel steel, reinforced concrete depending on the specific conditions. On the beam. The equipment is connected to the foundation fixing anchor screw, and the accessory equipment should be located near the main unit.
5. It is necessary to extensively refer to, absorb and quote similar unit equipment configuration drawings that have been produced and proved to be reasonable and reliable.
