A material level detection device for a small garbage incinerator

Abstract

The invention discloses a material level detection device for a small garbage incinerator, comprising a material level probe, a hoist, an encoder, a steel wire rope, a pulley block, a spring, a proximity switch 1, a bracket and a proximity switch 2; the material level probe Including probe rod, lifting ring, flange one, flange two, guide pipe and circular plate; the output shaft of the winch is equipped with an encoder for recording the travel distance of the probe; the winch, encoder, proximity switch The first and the second proximity switch are respectively connected with the computer control system. Because the invention adopts the simple combination of hoist, pulley block, steel wire rope and material level probe, the device has simple structure, convenient installation and disassembly, and easy maintenance. Because the present invention has adopted encoder and scale combined reading. It can not only realize automatic measurement, but also manually read the scale, and the process is flexible. Since the present invention adopts the proximity switch to preset the material level limit, there is no caliper phenomenon in the operation process, the measurement result is accurate, and the material level can be truly reflected.

Description

technical field [0001] The invention relates to a material level detection device, in particular to a material level detection device for a small garbage incinerator. Background technique [0002] The material level detection device is one of the key components of the waste incinerator. It is an important reference point for operators to monitor and operate the incinerator operation, and its measured value should accurately reflect the height of the incinerator furnace material level. So as to ensure the continuous and stable operation of the waste incinerator. [0003] Due to the relatively simple equipment of traditional small waste incinerators, the incinerators usually use intermittent manual feeding, the level of feeding automation is low, and the furnace material level is judged by manual observation. When the incinerator is running, the amount of fly ash and flue gas is large, the line of sight is cloudy, the error of manual observation is large, the material level ...

AI Technical Summary

Problems solved by technology

[0003] Due to the relatively simple equipment of traditional small waste incinerators, the incinerators usually use intermittent manual feeding, the level of feeding automation is low, and the furnace material level is judged by manual observation

When the incinerator is running, the amount of fly ash and flue gas is large, the line of sight is cloudy, the error of manual observation is large, the material level cannot be accurately judged, and the radiation heat at the observation place is strong, which poses a great safety and health hazard. The smoke overflowing from the observation port The gas directly enters the atmosphere and pollutes the environment

[0004] Chinese patent CN201276578Y discloses a new blast furnace material level detection device, which is mainly aimed at blast furnaces and is suitable for large-volume furnaces. The working conditions in the large-capacity furnace are complicated, and there are problems such as calipers that cannot accurately measure the actual material level

[0005] A large amount of blast furnace gas is produced in blast furnace production, and the gas dust and corrosion are serious. In addition, condensed water factors may easily cause the blast furnace material level probe to be stuck. Moreover, the furnace temperature of the blast furnace is extremely high, and the general probe cannot meet the working conditions of the blast furnace.

Blast furnace probes are generally composed of motors, brakes, probe transmission boxes, etc., mainly for volumes of 2000m 3 The above furnace has complex structure and high cost

However, the working conditions of the small waste incinerator furnace are simple, there is no caliper phenomenon, and the furnace volume is small and the temperature is low. It is not suitable to directly use the blast furnace material level detection device, and the cost is too high
