Abstract
A partition roller breakage alarm device of a roller kiln is suitable for the occasions of adopting a ceramic roller as the roller bottom of the kiln. A light shielding board is installed on the ceramic roller for detecting a radiating type optoelectronic switch, so that roller breakage can be found out timely, and alarming can be given out. By adopting a radiation-proof board and a cooling optoelectronic switch of an air cooling tube, normal working of the partition roller breakage alarm device can be ensured.
Description
Affiliated technical field
The utility model relates to a kind of roller kilns subregion breakage alarming device, the occasion at the bottom of being particularly useful for adopting ceramic rod as the kiln roller.
Background technology
Roller kilns are tunnel-type kilns that burner hearth is flat square type, and the saggar of loading stocks is placed on the roller-way by branched roller bar construction, the roller-way continuous operation, and product is steadily mobile to the kiln outlet from the kiln entrance, finishes preheating, sintering and cooling procedure.
Roller rod at the bottom of the kiln roller is chosen according to item technical indicators such as furnace temperature, furnace width, roller-way load-carryings, and ceramic material roller rod often becomes first-selection.Every meter length of roller kilns is installed roller rod 10-14 and is propped up, and the roller kilns ceramic rod quantity 500-700 that length is 50 meters props up.
Roller kilns move some months incessantly continuously, and single roller rod fracture defect occurs the run duration occasional, and this moment, the roller rod adjacent with fracture roller rod still supported saggar, as long as in time change fracture roller rod, equipment just can be kept stable operation.If untimely replacing fracture roller rod, adjacent roller rod fracture more with it, the bottom support face of saggar can not guarantee level, and the saggar run-off the straight that is fed forward will be bumped the roller rod in disconnected the place ahead, and fault coverage enlarges, and this moment must shutdown maintenance.
In order to guarantee the continuous operation of roller kilns, the operation conditions that requires the operator to make an inspection tour the roller rod is pinpointed the problems and is processed immediately.So increase operator's labour intensity, and relied on manual patrol can not guarantee each single roller rod fracture of in time finding.
Summary of the invention
In order accurately and timely to find roller kilns roll breakage fault and send alarm signal that the utility model provides a kind of roller kilns subregion breakage alarming device.
Roller-way is divided into some individual section (6 meters of every segment length) in the kiln of roller kilns, and each section is equipped with respectively the running of Motor Drive roller rod.One end (drive end) of every roller rod is connected with transmission mechanism, and the other end (driven end) is free end, is erected on the support roller.The shadow shield of 1/2 cylindrical shape is installed in every driven termination of roller rod, and each roller rod shadow shield setting angle of same section is identical.
Each section installation 2 cover optoelectronic switch is as detecting element, and optoelectronic switch covers all rollers rod shadow shields of this section along the irradiation of kiln length direction, and light path is passed through respectively upper semi-circle and the lower semi-circular of roller rod.When roller-way normally moved, each of same section roller rod operating angle speed was identical, and the shadow shield of each roller rod rotates synchronously, and 2 cover optoelectronic switch light paths are alternately blocked up and down, and it is normal that control circuit is judged as roller-way.If certain roller rod fracture, roller rod driven end no longer rotates with drive end, the shadow shield corner of other roller rods of the shadow shield of this roller rod and this section is asynchronous, the rule that 2 cover optoelectronic switch light paths are alternately blocked about having broken, control circuit is judged the roller-way operation irregularity, sends the roll breakage alarm signal.
This kind method can detect the fracture of generation roller rod within roller rod rotation one week (360 °).
The high ambient temperature that optoelectronic switch can tolerate is 55 ℃, and the roller kilns sidewall is installed about 80 ℃ of the environment temperature of optoelectronic switch position.In order to guarantee the optoelectronic switch normal operation, each optoelectronic switch is arranged local wind's device for cooling, installs the radiation proof baffle plate additional, make the temperature of optoelectronic switch be lower than 50 ℃.

Fig. 1 is the roll breakage checkout gear schematic diagram of 55 meters roller kilns, view direction: towards the driven limit of kiln body roller-way roller rod termination.55 meters roller kilns are divided into 9 sections along its length, and every section is driven by 1 variable-speed motor, is equipped with the roll breakage checkout gear that 1 cover is installed 2 correlation photoelectricity switchs.
Fig. 2 is roll breakage checkout gear optoelectronic switch, shadow shield scheme of installation, view direction: towards the kiln thorax, vertical with the roller rod.The shadow shield of 1/2 cylindrical shape is installed in every driven termination of roller rod, and each roller rod shadow shield setting angle of same section is identical.
The specific embodiment
Per 6 meters of live-roller gear is divided into a section in 9 of 55 meters roller kilns sections kilns in Fig. 1, and each section links to each other becomes complete rollgang.6 meters identical long sections of each roller rod operating angle speed are equipped with 2 cover correlation optoelectronic switches and form a roll breakage detecting unit.
Whether take the first paragraph roller-way as example: ST101A/101B, ST101C/101D are 2 cover correlation optoelectronic switches, and optoelectronic switch is installed on the support of being convenient to adjust, along the irradiation of kiln length direction, detect this section roller rod and rupture.Last of every section roller-way roller rod is subjected to the restriction of optoelectronic switch installation site not in the optoelectronic switch detection range, needs manual detection.In order to prevent the phase mutual interference of adjacent sections optoelectronic switch, the adjacent sections optoelectronic switch should be installed dorsad.
An end of every roller rod links to each other with the roll table transmission mechanism driving mechanism in Fig. 2, is drive end; The other end is erected on the support roller and rotates, and is Partner.This figure is the concrete structure of Partner.One identical with the roller rod outside diameter, and 1/2 columned used in sunshade board clip is fixed on roller rod Partner, and shadow shield length 150mm, 75mm are fixed on the roller rod, and 75mm stretches out roller rod termination and blocks as Photoelectric Detection.Roller rod center line is respectively installed up and down 1 cover correlation optoelectronic switch, when the roller rod rotates, and shadow shield or the light path of blocking an optoelectronic switch, or the light path of blocking simultaneously two optoelectronic switches, the roller rod rotates a week, and each logical light of light path of 2 cover photoelectricity switchs is once.Control circuit rotates the slowest time in a week as the setting value of the time relay with the roller rod, if do not reach in this time periods 2 each logical light requirement once of cover photoelectricity switch light path, sends this section roll breakage alarm signal.
