Abstract

The utility model relates to a vibration type anti-blocking device of a coal bucket used for a thermal power plant, which is characterized by comprising a coal scuttle, springs, a sieve plate and vibrators. A plurality of springs serve as middle elastic elements to be fixedly connected with the coal scuttle and the sieve plate, and the vibrators are fixed on the sieve plate. The vibration type anti-blocking device of the coal bucket has the advantages that the sieve plate and the connecting springs form an elastic system, the vibrators serve as shock excitation driving devices and enable the sieve plate to produce continuous vibration, and the number of the vibrators and the number of the springs can be selected according to the specific situations of the coal scuttle. The vibration type anti-blocking device aims at preventing blocking, once the blocking occurs, the vibration type anti-blocking device can clear the blocking by combining other mechanical modes, thereby being capable of effectively preventing and handling the blocking problem of the coal bucket.

Description

Oscillating mode coal bunker anti-block apparatus

Technical field

The utility model relates to coal-fired load transfer device field, especially relates to the oscillating mode coal bunker anti-block apparatus that a kind of thermal power plant uses.

Background technology

At present, the conveyer of coal is belt pulley and belt conveyor normally, and feeding device mainly is a coal breakage bucket etc.Coal stops up through regular meeting in the outlet of coal breakage bucket, and particularly under the relatively moister situation of weather, the user has to adopt various measures in case the obstruction of falling stop coal bunker.At present in the application of thermal power plant,, generally be to use poker to carry out artificial block clearing if coal bunker stops up, wasting manpower and material resources so not only, and influence the efficient of thermal power plant.

Summary of the invention

The utility model technical matters to be solved is to propose a kind of oscillating mode coal bunker anti-block apparatus to above-mentioned prior art, through the continuous shaking effect of sieve plate in the coal tube, makes attached to the coal on the sieve plate is loosening and scatters, and is unlikely to bonding and stops up.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: oscillating mode coal bunker anti-block apparatus; It is characterized in that including scuttle, spring, sieve plate and vibrator; A plurality of springs are connected as middle elastic members and scuttle and sieve plate, and vibrator is fixed on the sieve plate.

The advantage of the utility model: by sieve plate be connected spring and constitute elastic system; With the vibrator is the exciting actuating device, makes sieve plate produce continuous shaking, and vibrator can be selected according to the particular case of coal bunker with the number that is connected spring; The utility model is conceived to anti-blocking; And in a single day stopping state takes place, and also can combine the block clearing as early as possible of other mechanical system, thus the blockage problem of prevention of ability actv. and processing coal bunker.

Description of drawings

Fig. 1 is the Facad structure scheme drawing of the utility model;

Fig. 2 is the Facad structure scheme drawing of sieve plate.

Among the figure, 1-scuttle, 2-spring, 3-sieve plate, 4-vibrator.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but this explanation can not constitute the restriction to the utility model.

Like Fig. 1, shown in Figure 2, oscillating mode coal bunker anti-block apparatus includes scuttle 1, spring 2, sieve plate 3 and vibrator 4; A plurality of springs 2 are middle elastic members; Be connected with scuttle 1 and sieve plate 3 respectively, vibrator 4 is fixed on the sieve plate 3, and sieve plate is produced periodic mechanical exciting effect.

Continuous drop impact down and actuating device at fire coal are under the active exciting effect of vibrator 4, and sieve plate 3 with the elastic system that spring 2 is constituted continuous shaking can take place, and make attached to the coal on the sieve plate 3 is loosening and scatter, and are unlikely to bonding.In coal bunker charging process, starting actuating device is vibrator 4, can effectively prevent to stop up; If, also can combine other mechanical system to remove blockage problem rapidly taking place to stop up back startup actuating device.

The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
