Description

Double inlet and outlet coal mill steel ball adder

Technical field

The utility model relates to boiler technology field, especially double inlet and outlet coal mill steel ball adder.

Background technology

When coal pulverizer electric current lower than normal current 5% time, need to be at the coal pulverizer online steel ball that supplements in service,

The problem that adds steel ball device existence using is at present complex structure, and complex operation needs the skilled operating personnel that grasp operative skill to repeat always and adds steel ball one secondary door. Fault rate is high, and owing to adding, ball process operation is frequent, and machinery, electric-controlled parts jam, scaling loss, distortion are common. Maintenance expense is high, eliminates fault and need set up scaffold, change parts such as damaging insertion plate door, actuator. Environmental pollution, owing to being positive pressure system, maloperation while adding ball, mechanical jam, the actuator leakage of pulverized coal that all can cause out of control. Potential safety hazard, the each defect elimination of maintainer need be carried out in the environment of work high above the ground, narrow space, high-temperature dust.

Summary of the invention

The purpose of this utility model is exactly the defect existing for prior art, provides a kind of reasonable in design practicality, double inlet and outlet coal mill steel ball adder with low cost, simple to operate and safe and reliable. its technical scheme is: on body, be provided with charge door, be provided with dense block at a upper lateral part of body and press ring, be provided with chamber housing outward at chamber, upper flange and chamber housing are integrally welded, lower flange and lower charge pipe are integrally welded, the tapered spiral cell body of upper charge pipe and chamber housing combine by Screw assembly, upper flange and lower flange close bolt with six handles and install sealing gasket locking additional, the tapered spiral cell body of upper charge pipe coordinates and forms ring rotation spout with lower charge pipe in chamber, air inlet pipe connects malleation compressed air gas source, in air inlet pipe, be provided with manual ball valve.

The beneficial effects of the utility model: reasonable in design practicality, with low cost, easy to operate, solve that fault rate is high, maintenance expense is high, problem of environmental pollution, improve business efficiency and the economic benefit of enterprise, be applicable to generally promoting the use of.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As shown in Figure 1, double inlet and outlet coal mill steel ball adder, is mainly pressed ring 2, chamber housing 3, chamber 4, the tapered spiral cell body 5 of upper charge pipe, ring rotation spout 6, lower charge pipe 7, is formed closing bolt 8, manual ball valve 9, air inlet pipe 10, upper flange 11 and lower flange 12 by charge door 1, dense block, on body, be provided with charge door 1, be provided with dense block at a upper lateral part of body and press ring 2, outside chamber 4, be provided with chamber housing 3, upper flange 11 is integrally welded with chamber housing 3, lower flange 12 is integrally welded with lower charge pipe 7, the tapered spiral cell body 5 of upper charge pipe combines by Screw assembly with chamber housing 3, upper flange 11 closes bolt 8 with six handles of lower flange 12 use and installs sealing gasket locking additional, the tapered spiral cell body 5 of upper charge pipe forms ring rotation spout 6 with lower charge pipe 7 in interior cooperation of chamber 4, air inlet pipe 10 connects malleation compressed air gas source, in air inlet pipe 10, be provided with manual ball valve 9.

The utility model technological process: the tapered spiral cell body 5 of upper charge pipe combines by Screw assembly with chamber housing 3, can be adjusted at the height in chamber 4 by rotating the tapered spiral cell body 5 of upper charge pipe. Upper flange 11 and six handles of lower flange 12 use are closed to bolt 8 and install sealing gasket locking additional, the tapered spiral cell body 5 of upper charge pipe forms ring rotation spout 6 with lower charge pipe 7 in interior cooperation of chamber 4. Air inlet pipe 10 connects malleation compressed air gas source, open manual ball valve 9 toward the interior pressurising of chamber 4, now, according to the pressure height that carrys out gas source of the gas, in rotation, the tapered spiral cell body 5 of charge pipe is adjusted the aperture size of annular swiveling jet nozzle 6, will produce needed negative pressure value at adder charge door 1. Negative pressure value is stablized and is met and presses ring 2 with dense block after reinforced state and be locked, and the utility model integral installation has been debugged. As stable in user's malleation compressed air gas source, after this steel ball adder once mounting debugging, daily need adjusted, safeguarded, each steel ball that adds only need first be opened manual ball valve 9 and opens charge door 1 shutoff again and can use, after interpolation steel ball completes, after tight charge door 1 shutoff, close again manual ball valve 9.

The utility model has effectively solved that double inlet and outlet coal mill adds that device complexity, complex operation, the fault rate of steel ball device is high, maintenance expense is high, environmental pollution, potential safety hazard present situation.
