Abstract
The utility model discloses an anti-blocking alarming device, which comprises a sleeve, a pressure pushing rod, a pressing spring, and an elastic sheet. The elastic sheet is fixed at the inner side of a feeding port through a hinge; the sleeve is fixed on a sleeve frame; the sleeve frame is fixed at the outer side of a feeding channel. The pressing spring is sleeved outside the pressure pushing rod that is arranged inside the sleeve to pass through the side wall of the feeding channel to be contacted with the elastic sheet; the side end of the feeding channel of the pressing spring is fixed on the pressure pushing rod; a steel wire rope passes through one end of a steel wire rope pipe to be fixed on the end part of the pressure pushing rod through an adjusting nut, and the other end of the steel wire rope is fixed on a travel switch; under the pressure role, the elastic sheet is deformed downward to push the pressure pushing rod to move outward to drive the travel switch to act. The travel switch acts to start an alarming control circuit and an anti-blocking control circuit. The elastic sheet restores the deformation when the pressure disappears, and the travel switch resets. The anti-blocking alarming device has advantages of novel structure, sensitive and reliable action, can solve problems of blocking of the feeding channel for the biomass power plant, and is suitable for popularizing and using.
Description
Technical field
The utility model relates to the biomass energy development field, the warning device of the pre-anti-clogging of particularly a kind of biomass fuel feeder channel.
Background technology
The biological energy source generation technology developed comparatively fast in recent years in China, built up 100 surplus in family's biomass electric power plant, ubiquity feeding system feed stops up a difficult problem.
Biomass fuel after the fragmentation has polymorphisms such as thread, fibrous, does not have the physical property of particle.In course of conveying, because the characteristics of light, the easy conglomeration of biomass fuel compact substance, biomass fuel is under the conveying of screw feeder, stop up in the feed opening conglomeration easily, if in time do not find, it will be more and more serious stopping up, and can only lean on and manually slowly dredge passage, influenced the stability of boiler combustion, feed causes the boiler extinguishment accident because stop up in time when serious.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art and a kind of novel structure is provided, and is with low cost, the anti-blocking warning device that reliability is high.
The purpose of this utility model is achieved by following technical proposals:
A kind of anti-blocking warning device, comprise sleeve, pressure push-rod, stage clip, shell fragment, described shell fragment fixes on described feed opening inboard by hinges fixing, described sleeve is fixed on the described sleeve rack, described sleeve rack is fixed on the described blanking channel outside, described pressure push-rod is with stage clip outward and is built in the sidewall that runs through blanking channel in the described sleeve and contacts with described shell fragment, the blanking channel side of described stage clip is fixed on the described pressure push-rod, described steel wire penetrating steel rope conduit one end is fixed on the pressure push-rod end by setting nut, and the other end is fixed on the travel switch; When promoting pressure push-rod, the downward deformation of the described shell fragment of pressure effect outwards moves the action of drive travel switch, described travel switch action launching alarm control circuit and anti-blocking control circuit.
In the utility model, described shell fragment pressure disappears and recovers deformation, and travel switch resets.
The utility model has following advantage owing to adopt technique scheme:
1, sleeve, pressure push-rod, stage clip, shell fragment unitized design are rational in infrastructure, and resistance is less, and sensitivity is better.
2, the blanking channel temperature is higher, adopts steel rope and steel rope conduit that the retaining pressure signal is drawn the local preferably travel switch of installing of environment, has improved the reliability of device.
3, stage clip can guarantee that shell fragment recovers deformation, the sensitieness of energy safety action and recovery after pressure disappears.
4, control circuit is designed to alarm control circuit and anti-blocking control circuit, can automatically information indicating be given the operations staff and stop feed automatically rapidly, and pre-anti-clogging is serious, does not stop up and will recover automatically.
5, anti-blocking control circuit circuit layout protection throw and move back function, when having eliminated anti-blocking warning device fault to the influence of system.
In sum, described utility model---anti-blocking warning device has novel structure, and is with low cost, can reliably prevent the biomass electric power plant blanking channel to stop up, and is suitable for promoting the use of.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of anti-blocking warning device is described.
Shown in Fig. 1 to 5, a kind of anti-blocking warning device, comprise sleeve 1, pressure push-rod 2, stage clip 5, shell fragment 3, described shell fragment 3 is fixed on described feed opening 11 inboards by hinge 4, described sleeve 1 is fixed on the described sleeve rack 6, described sleeve rack 6 is fixed on described blanking channel 11 outsides, described pressure push-rod 2 is outer to be with stage clip 5 and to be built in the sidewall that runs through blanking channel 11 in the described sleeve 1 and to contact with described shell fragment 3, blanking channel 11 sides of described stage clip 5 are fixed on the described pressure push-rod 2, described steel rope 7 passes steel rope conduit 8 one ends and is fixed on pressure push-rod 2 ends by setting nut 10, and the other end is fixed on the travel switch 9; When promoting pressure push-rod 2, the described shell fragment 3 downward deformation of pressure effect outwards move 9 actions of drive travel switch, described travel switch 9 action launching alarm control circuits and anti-blocking control circuit.
In the utility model, described shell fragment 3 pressure disappear and recover deformation, and travel switch 9 resets.
It is that three blanking channels are designed together that the general design of circulating fluidized bed boiler has three feed openings, alarm control circuit and anti-blocking control circuit.During use, when blanking passage 11 blanking amounts surpass to allow maximum, the shell fragment 3 generation deformation that is under pressure, travel switch 9 actions, cooresponding indicator lamp HR is bright, alarm bell GL jingle bell, corresponding feeder stops automatically, can recover immediately after stopping blanking; Only need the cooresponding protection throwing of anti-blocking control circuit during as plant failure and back out to close the Q closure, the Q branch is opened i.e. protection input.
