Description
Technical Field
The utility model belongs to the field of machinery, relate to the rotary kiln, concretely relates to rotary kiln tail negative pressure adjusting device.
Background
In the production process of the rotary kiln, negative pressure is provided through the smoke exhaust machine, kiln tail smoke is dedusted after being cooled by the mechanical cooler, qualified smoke is discharged after being dedusted, the smoke is discharged in the process of passing through the mechanical cooler, the smoke volume adjustment amount passing through the mechanical cooler is small due to the fact that the area of an inner discharge pipe of the mechanical cooler is determined, and the kiln tail negative pressure cannot be adjusted according to specific needs in the production process. The adjustment of the kiln condition of the rotary kiln is delayed, and the productivity exertion is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a rotary kiln tail negative pressure adjusting device solves the problem that rotary kiln tail negative pressure can't be adjusted according to concrete needs.
The utility model adopts the technical proposal that: the utility model provides a rotary kiln tail negative pressure adjusting device, includes the rotary kiln, and the exhanst gas outlet and the mechanical power cooler entry of rotary kiln tail are put through mutually, and mechanical power cooler export and dust remover entry are put through mutually, are equipped with the by-pass pipeline between the entry of mechanical power cooler and the dust remover entry, through the by-pass pipeline intercommunication, are equipped with the governing valve on the by-pass pipeline.
Preferably, the flue gas outlet of the kiln tail of the rotary kiln is communicated with the inlet of the mechanical cooler through an air inlet pipeline, and the outlet of the mechanical cooler is communicated with the inlet of the dust remover through an air outlet pipeline.
The bypass pipeline is arranged between an air inlet pipeline at the inlet of the mechanical cooler and an air outlet pipeline at the inlet of the dust remover and is communicated with the inlet pipeline.
The bypass pipeline is installed between the same sides of the air inlet pipeline and the air outlet pipeline of the mechanical cooler.
As a further improvement, the air outlet pipeline is internally provided with a temperature measuring instrument.
The regulating valve and the temperature measuring instrument are mutually interlocked.
The exhaust port of the dust remover is connected with the smoke exhauster.
The smoke outlet of the smoke exhaust machine is connected with a smoke tube.
The utility model has the advantages that:
1. the utility model discloses the export of mechanical force cooler meets with the dust remover through air-out pipeline, is equipped with the by pass line between the entry of mechanical force cooler and the dust remover entry to install the governing valve on the pipeline, the mechanical force cooler flue gas flow is adjusted on line to be convenient for, reaches the purpose of adjusting rotary kiln tail negative pressure through governing valve 8, improves rotary kiln output, reduction in production cost.
2. The inlet of the dust remover is provided with a temperature measuring instrument, the temperature of the dust removing inlet is not more than 220 ℃, the regulating valve and the temperature measuring instrument are interlocked, and the regulating valve is automatically closed when the temperature of the dust removing inlet exceeds 220 ℃, and only the mechanical cooler works, so that the burning loss of a dust removing cloth bag of the dust remover is avoided.
Drawings
FIG. 1 is a schematic structural diagram of the present invention;
in the figure: 1. the system comprises a mechanical cooler 2, a discharge pipe 3, an air inlet pipeline 4, an air outlet pipeline 5, a dust remover 6, a cooling fan 7, a bypass pipeline 8, a regulating valve 9, a smoke exhauster 10, a chimney 11 and a temperature measuring instrument.
Detailed Description
The present invention will be described in further detail with reference to the following specific drawings;
a kiln tail negative pressure adjusting device of a rotary kiln comprises the rotary kiln, wherein a smoke outlet of the kiln tail of the rotary kiln is communicated with an inlet of a mechanical cooler 1 through an air inlet pipeline 3, and an outlet of the mechanical cooler 1 is communicated with an inlet of a dust remover 5 through an air outlet pipeline 4. A bypass pipeline 7 is installed between the air inlet pipeline 3 at the inlet of the mechanical cooler and the air outlet pipeline 4 at the inlet of the dust remover on the same side, the upper end of the bypass pipeline 7 is communicated with the tail of the air inlet pipeline 3, the lower end of the bypass pipeline 7 is communicated with the head or the middle of the air outlet pipeline 4, an adjusting valve 8 for adjusting the air flow is installed on the bypass pipeline 7, an exhaust port of the dust remover 5 is connected with a smoke exhaust machine 9, and a smoke exhaust port of the smoke exhaust machine 9 is connected with a smoke cylinder 10. In order to prevent the gas entering the dust remover from being too high in temperature and damaging a dust removing cloth bag, a temperature measuring instrument 11 is arranged at a dust removing inlet (in the air outlet pipeline 4), and the regulating valve 8 and the temperature measuring instrument 11 are arranged in an interlocking manner.
When the kiln tail negative pressure of the rotary kiln needs to be adjusted, and the flow in the mechanical cooler cannot meet the requirement, the dust remover 5 and the smoke exhaust 9 are opened, the smoke flow is controlled by adjusting the adjusting valve 8 on the bypass pipeline 7, the smoke flow entering the mechanical cooler is adjusted by the adjusting valve 8, and the purpose of adjusting the kiln tail negative pressure of the rotary kiln connected with the mechanical cooler is achieved.
The utility model discloses an governing valve 8 and temperature measuring instrument 11 are each other for interlocking, and the temperature that the dust removal entry set up temperature measuring instrument 11 is not more than 220 ℃, self-closing governing valve 8 when dust removal entry temperature overtemperature avoids the dust removal sack to burn out.
