Technical field
The utility model belongs to thermal powerplant run coal bin storage technique field, is specifically related to the anti-blocking machine of a kind of flow-guiding type vibration rotary-cut run coal bin.
Background technology
Run coal bin coal spout blockage problem is perplexing the normal operation in firepower power plant for a long time.Cause the reason of its obstruction, the one, the pyramidal structure of coal spout, the coal spout tapering is big more, and drag coefficient is big more; The 2nd, former coal particle viscosity causes, and the factor that influences viscosity mainly is moisture and impurity; The 3rd, due to coal spout coal breakage speed and the feeder delivery speed difference, feeder is carried too late, must cause constantly depositing in the coal spout coal.So the process that the run coal bin coal spout stops up generally is the bonding tube wall of beginning, along with increasing and the increase of bonding back friction force of chute blockage amount, from bottom to top, from outer to inner, extend with the center vertically gradually, so that formation center stream, until obstruction.How susceptible to plugging position is upwards about 1.5 meters of coal spout end openings.Therefore, solving the key issue that coal spout stops up, be cut off sprue and tube wall bonding, and the point of penetration that mediation is stopped up then is the application of diversion technology.
The utility model content
For effectively solving the blockage problem of thermal power plant's run coal bin coal spout, the purpose of this utility model is to provide a kind of compact conformation, safe and reliable, does not have the anti-blocking machine of flow-guiding type run coal bin that stops up in the coal spout.
For achieving the above object, the technical solution adopted in the utility model: the anti-blocking machine of this flow-guiding type run coal bin is made of connection and actuating device two parts, described connecting bridge has last straight tube, the rotatable Taper Pipe of lower straighttube and centre portion, last straight tube and the welding of run coal bin coal spout lower flange, lower straighttube is connected with feeder coal inlet nut flange, adopt between Taper Pipe and the last lower straighttube and be tightly connected, be provided with a pair of rotary-cut cutter that is fixed on the lower straighttube in the Taper Pipe, the Taper Pipe periphery is fixed with bull gear, bull gear is driven by actuating device, be positioned at the bottom surface of the carrying roller support bull gear on the support, it is characterized in that: the bottom surface of described bull gear is provided with groove, and the layout of described groove location is provided with consistent with carrying roller.
The bottom of described Taper Pipe is provided with pressure port, and pressure port is by spring application, and the outside of the corresponding pressure port of Taper Pipe is provided with recovering hopper, is provided with the scraper plate that is fixed on the Taper Pipe in the recovering hopper, and the bottom of recovering hopper is provided with mozzle.
Adopt the beneficial effect of technique scheme: the Taper Pipe inwall of the anti-blocking machine of this flow-guiding type run coal bin is fitted with the rotary-cut cutter that is fixed on the lower straighttube, the Taper Pipe rotation produces the rotary-cut campaign with respect to the rotary-cut cutter, can excise the long-pending coal that is bonded on the Taper Pipe inwall, can the downward rotary-cut of coal be promoted coal downwards again, reach anti-blocking purpose, rotary-cut cutter intensity, resistance to abrasion are enough, symmetric arrangement again, stressed evenly, entire mechanism operates steadily.The bottom surface of bull gear is provided with groove, the layout of described groove location is provided with consistent with carrying roller, carrying roller is supporting whole Taper Pipe by bull gear, drives the Taper Pipe rotation by actuating device, in rotary course, when carrying roller rotates to groove location, whole Taper Pipe falls, and produces vibration, makes the coal, the sprue that are bonded in the Taper Pipe on the tube wall come off or shake loose, solved the blockage problem of coal in Taper Pipe, made blanking more smooth and easy.When carrying roller screwed out groove, carrying roller held up Taper Pipe.Perseveration like this in the rotary course of Taper Pipe makes Taper Pipe produce periodically to throw and shakes, and the smooth and easy conveying that this oscillating action has ensured coal has realized anti-blocking purpose.The bottom of described Taper Pipe is provided with pressure port, and pressure port is strained by spring, and the outside of the corresponding pressure port of Taper Pipe is provided with recovering hopper, is provided with the scraper plate that is fixed on the Taper Pipe in the recovering hopper, and the bottom of recovering hopper is provided with mozzle.Under abnormal condition, as exceeding certain limit when the raw coal water ratio, sprue in the rotation Taper Pipe can have certain elasticity with the increase of raw coal viscosity, vibration rotary-cut system is with ineffective, and this moment improving constantly along with the sprue surface pressure, being located at the pressure port of Taper Pipe bottom will open automatically, sprue outer ring raw coal will flow out along pressure port, enter recovering hopper, and under the effect of scraper plate, flow to feeder through mozzle, along with the rotation of Taper Pipe, in Taper Pipe, form the annulus hole, the sprue that loses support will fall in effect following moment of upper pressure and self gravitation, had solved the arch camber blockage problem of wet coal.Compared with prior art, compact conformation, safe and reliable to operation, thoroughly solved the blockage problem of coal in course of conveying.
