Abstract
The utility model relates to a novel speed measuring device of a draught fan of a converter, which comprises a bearing pedestal, a rotating shaft, a transition shaft, an induction magnetic disc, a support, a locating block, a sensor and a locking nut of the sensor, wherein the rotating shaft is arranged on the bearing pedestal; the transition shaft is connected with the rotating shaft, the induction magnetic disc is connected with one end of the transistion shaft; the support is connected with the bearing pedestal; the locating block is connected with the lower end of the support; and the sensor is connected with the locating block. An L-shaped groove is machined on the locating block; the sensor is arranged inside the L-shaped groove; a square blocking block is arranged at one end of the sensor; adjusting screw holes are machined at two transverse sides of the locating block in a coaxial line; adjusting screw rods are arranged inside the adjusting screw holes; and the width of the L-shaped groove is larger than the diameter of the adjusting screw holes. The novel speed measuring device can eliminate the safety potential hazard of regulating the sensor, substantially shortens the regulation time, can accurately detect the revolving speed of the draught fan and is simple to operate.
Description
Technical field
The utility model relates to proofing unit, specifically belongs to the speed measuring device of converter blower fan.
Background technology
Blower fan is the key equipment of coal-gas recovering in the converter steelmaking process, the coal gas of converter toxicity that converter steelmaking produces is extremely strong, need blower fan in time to take purification away, so very high in the converter steelmaking, for example constantly in the monitoring state to parameters such as its rotating speed, vibrations for the fan operation parameter request.In a single day the rotating speed of converter blower fan is lower than prescribed value, will report to the police at once and start automatically to stop production sequence.At present, kind surplus the mode of measuring rotation speed of fan has 10, wherein a kind of is to adopt the magneticinduction switch that tests the speed, and promptly responds to the magnet that carries on the fan rotor and forms pulse signal and test the speed.Using this magneticinduction switch advantage that tests the speed is that test the speed switch and fan rotor is contactless, there are not wearing and tearing, reliable, easy for installation, shortcoming is test the speed switch and the relatively strictness of rotor magnet controlled distances, receive according to the magneticinduction signal strong and weak, need be in the fan operation process to the front and back of the switch that tests the speed and about distance suitably regulate, the setting device of blower fan velometer be exactly at this kind test the speed switch front and back and about adjusting and design.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of rotation speed of fan to measure accurately, and magneticinduction is stable, the speed measuring device of the converter blower fan that dismounting is simple and efficient.
Realize the technical measures of above-mentioned purpose:
The speed measuring device of novel converter blower fan, the set nut of preset pieces, the transmitter that is connected with preset pieces and the transmitter that is connected by the rotating shaft on bearing support, the bearing support, the transition axis that is connected with rotating shaft, the induction disk that is connected with transition axis one end, the support that is connected with bearing support, support lower end is formed, it is characterized in that: the L shaped groove of processing on preset pieces, transmitter is contained in the L shaped groove; One end of transmitter is equipped with square block; Both lateral sides coaxial line at preset pieces is processed with the adjusting screw, in regulating screw adjusting screw(rod) is housed; The width of L shaped groove is greater than the diameter of regulating screw.
It is characterized in that: adjusting screw(rod) is vertical with transmitter to be installed.
It is characterized in that: the width of L shaped groove is greater than 4～8 millimeters of the diameters of regulating screw.
The utility model is compared with prior art:
1, eliminated the maintenance personnel regulates transmitter in equipment running process hidden danger;
2, from the Fan Regulation time by original about 1 hour, shortening to only needed to mix up now in 10-15 minute, had saved the repair time;
3, can accurately detect rotation speed of fan, for guaranteeing role is played in safety in production;
4, the maintenance personnel no longer regulates the front and back position of transmitter with feel or experience, finely tunes about only carrying out with a platelet hand adjustment joint set nut, can control the high, medium and low precision of blower fan well.

Embodiment
Do detailed description below in conjunction with accompanying drawing:
The speed measuring device of novel converter blower fan, the set nut 8 of preset pieces 6, the transmitter 7 that is connected with preset pieces 6 and the transmitter 7 that is connected by the rotating shaft 2 on bearing support 1, the bearing support 1, the transition axis 3 that is connected with rotating shaft 2, the induction disk 4 that is connected with transition axis 3 one ends, the support 5 that is connected with bearing support 1, support 5 lower ends is formed.The L shaped groove 9 of processing on preset pieces 6; In the L shaped groove 9 of being contained in of transmitter 7; The front end of transmitter 7 is by the square block 10 that is threaded; Regulate screw 11 in the processing of the both lateral sides coaxial line of preset pieces 6, debug joint screw rod 12 in regulating screw 11, adjusting screw(rod) 12 is also fixed by nut; 7 one-tenth vertical installations of two adjusting screw(rod)s 12 and transmitters; The diameter of regulating screw 11 than the width of L shaped groove 9 big 4 millimeters/6 millimeters/8 millimeters.
When needs are carrying out front and back when regulating to transmitter 7, operator can realize transmitter 7 anteroposterior accurate adjustings by instrument or with hand adjustment joint set nut 8, thereby make transmitter 7 accurately detect the rotating speed of converter blower fan, realize safety in production.
