Description
Technical field
The utility model belongs to single roll crusher tool field, is specifically related to a kind of single roll crusher for the fragmentation of rear of sintering machine sintering deposit.
Background technology
Sintering machine is applicable to the sintering work of large-scale iron and steel industry sintering plant, and it is the main equipment in down draft sintering process, can be by different components, and varigrained fine ore, rich ore powder sinters piece into, and part is eliminated sulphur contained in ore, the objectionable impurities such as phosphorus.Single roll crusher is the equipment for the fragmentation of rear of sintering machine sintering deposit, and the bulk sintering deposit that its purposes is mainly got off to sintering pallet carries out fragmentation, is convenient to that sintering deposit sieves, whole grain and transport; Another effect is the impact of buffering bulk sintering deposit to screening operation machinery, and balanced sintering mineral aggregate stream distributes.Whether the operation quality of single roll crusher directly has influence on SINTERING PRODUCTION normal; once breaking down, single roll crusher produces long-time shutdown by directly causing; cause serious economic loss, so single roll crusher is all the object of paying close attention in production run all the time.
At present, in prior art, for the single roll crusher of rear of sintering machine sintering deposit fragmentation, in long-term use procedure, easily there is the fault of connecting bolt fracture in the shaft coupling of its installing in the time of oepration at full load, causes the situation of breaker roll stall.Above-mentioned fault is difficult to be found in time from Central Control Room by producers; make to be with out of order single roll crusher continuous service; and then cause the situation that occurs serious putty on sintering machine; and cause the damage to the plant equipment such as machine, sintering machine of plate on sintering work line; shutdown causes the accident; not only affect carrying out smoothly of SINTERING PRODUCTION, and the sintering work line length time because shutdown stops producing, also significantly increase producers' maintenance difficulty and work load.
Therefore applicant considers how to realize in the time being used for the single roll crusher shaft coupling of rear of sintering machine sintering deposit fragmentation and breaking down and cause breaker roll stall, the motor of this single roll crusher can stop operating fast.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, can detect rapidly and accurately breaker roll shaft coupling stall fault, and the single roll crusher for the fragmentation of rear of sintering machine sintering deposit that can quick shutdown; Serious putty be can avoid and device damage, stopping production caused.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of single roll crusher for the fragmentation of rear of sintering machine sintering deposit, comprise motor, shaft coupling, reductor and breaker roll, the output shaft of described motor is connected with the power shaft of described reductor by shaft coupling, and described breaker roll is fixedly installed on the output shaft of described reductor; It is characterized in that: also comprise sensor block and slip detector; Described sensor block is arranged on the output shaft of described reductor and is circumferentially uniformly distributed along output shaft; Described slip detector comprises controller and sensor; On described controller, there is power interface and normally closed output, wherein, the control loop of the described motor of described normally closed output series connection access; The test side of described sensor is closed on and just to the outer face away from output shaft on described sensor block, the signal output part of described sensor is connected with described controller signals, and described sensor is for detection of sensor block.
Single roll crusher for the fragmentation of rear of sintering machine sintering deposit of the present utility model, when use, producers are from Central Control Room is opened motor, start slip detector, the sensor block of sensor on slip detector on can the output shaft of procuratorial work reductor, and detection signal is delivered to controller, thereby measure the rotating speed of speed reducer output shaft.In the time breaking down for the single roll crusher shaft coupling of rear of sintering machine sintering deposit fragmentation and cause breaker roll stall (the output shaft stall of reductor), controller can detect breaker roll shaft coupling stall fault rapidly and accurately, and the normally closed output that outputs control signals to the control loop of series connection access motor disconnects, thereby Motor Control loop is disconnected, can make motor to stop operating fast, meanwhile, producers also can find the stall signal of motor in time in Central Control Room, thereby can take fast respective handling measure, at utmost avoid causing damage because of above-mentioned fault, also further guaranteed the reliable of rear of sintering machine sintering deposit crushing operation, safe operation.
As preferably, described sensor block is arranged at one end away from described reductor on the output shaft of described motor.
Like this, on the output shaft of motor, away from one end of described reductor, there is larger space, be beneficial to the installation of sensor block.Above-mentioned improvement project is also convenient to the existing single roll crusher for the fragmentation of rear of sintering machine sintering deposit to implement transformation, thereby obtains safer, reliable operational effect.
As improvement, the utility model also comprises the bracing frame for supporting described sensor, and support frame as described above upper end has the clamp port of U-shaped structure, and lower end is fixed on described ground; Described sensor is bar shaped, and level is clamped on described clamp port.
Implement after above-mentioned improvement, bracing frame lower end is fixed on ground, and upper end has the clamp port of U-shaped structure, and like this, bracing frame can provide the support of surely leaning on to sensor, detects accurately data thereby help sensor to obtain.In addition, the sensor of bar shaped, level is clamped on after the clamp port of U-shaped structure on bracing frame, not only be convenient to inspecting of on-the-spot producers, also be convenient to, in the time that sensor breaks down, it be changed fast, and then improve this slip detector maintenance, maintenance efficiency.
As preferably, the quantity of described sensor block is four.
Implement after above-mentioned improvement, because of the output shaft rotating speed lower (being usually less than 8 revs/min) of reductor in the utility model, after the sensor block that the output shaft around reductor circumferentially evenly arranges is four, not only can avoid the sensor that causes because of sensor block quantity very few (being less than 3) to detect frequency low, cause the hysteresis of fault detect.Also can avoid the sensor detection frequency that too much (more than 5) cause because of sensor block quantity high, and then bring excessive data processing load (controller that so just needs to adopt better data-handling capacity, certainly will bring higher use cost) to controller.When the quantity of visible sensor block is four, not only can reduce cost of installation and use, also can support the use to obtain desirable tach signal collection effect with sensor and controller.
Compared with the existing technology, the utility model is for the single roll crusher of rear of sintering machine sintering deposit fragmentation, in the time that shaft coupling breaks down and cause breaker roll stall, can stop fast, and then reduce because of this fault and bring series destruction and loss, guarantee safer, production operation reliably.That the utility model also has is simple and reasonable, implement advantage fast and easily, is also applicable to the existing single roll crusher for the fragmentation of rear of sintering machine sintering deposit to transform, thereby obtains more safe and reliable production operation.
