Abstract

The utility model relates to an automatic ash-expelling control device for a boiler deduster. An electromagnet 2 of a mechanical driving device is fixed in a box body 3; a core iron 1 is inlaid in a winding slot 14; the lower end of the core iron is fixed with a connecting rod 4; the other end of the connecting rod is fixed on a fulcrum 15 on the upper end of a three-fulcrum lever 6, another fulcrum 16 is inlaid on a fixing plate 5 through a shaft, and a lower fulcrum 17 is inlaid on the middle part of a translating arm 10 through the shaft; the translating arm is inlaid on a fixed pulley 11 on a bracket 8; a fixed pulley 9 on the back end of the translating arm is connected with a wedge-shaped block 13 which is fixed under an ash-expelling door 19; a return spring 12 is connected with the position between the translating arm and the bracket. The utility model realizes the automatic control on the switching of the ash-expelling door of the deduster, and the manual operation is left out.

Description

Boiler dust remover automatic removing dust control device

Boiler dust remover automatic removing dust control device belongs to environmental protection equipment

Existing ash-draining gate with the supporting use deduster of boiler all needs the operative employee to carry out manually-operated to the scene, because environment is abominable, operation is heavy, this work meeting influences operative employee's physical and mental health.Again because poor management is difficult to reach timely ash discharge.Even so deduster with the boiler cigarette except dirt, but owing to can not in time discharge dust, the dust of accumulation still can be discharged to by air exhauster and go in the air to pollute in the deduster.

The purpose of this utility model is the scene that a kind of operative employee of development does not use deduster ash door, just can control mechanical actuation device the ash door of deduster is opened ash discharge automatically as long as press button (or self-timing) by circuit, arrange behind the ash again can be automatically with grey the control device that close automatically of deduster.

The utility model is made up of control circuit and mechanical actuation device.Mechanical actuation device is made up of casing, electromagnet, core iron, three pivot point levers, translation arms, back-moving spring, wedge.Electromagnet is fixed on the fixed head, and fixed head is fixed in the casing, and core iron is set in the magnet spool groove, and a connecting rod is fixed in the lower end of core iron, and the other end of connecting rod is fixed on the fulcrum of three pivot point levers upper end.Another fulcrum of three pivot point levers upper end is set on the fixed head by axle, and fixed head is fixed in the casing, and the lower fulcrum of three pivot point levers is set in the middle part of translation arms by axle.Translation arms is set in the chute of support, is fixed with a fixed pulley below the chute, the lower surface of translation arms drop on fixed pulley above, the upper end of support is fixed on the outside of casing.Fix a fixed pulley on the rear end face of translation arms, back-moving spring is connected between the lower end of the front end of translation arms and support.Wedge be fixed on the deduster ash-draining gate below.The fixed position of casing and support should make the fixed pulley on the translation arms rear end face by wedge the ash door be closed when electromagnet cuts off the power supply just, and when electromagnet is switched on, because the degree that the reach of translation arms can be opened the ash door again.

The utility model realized the automatic control to the opening and closing of boiler dust remover ash-draining gate, cancelled the trouble that the operative employee need arrive the deduster execute-in-place, avoided the adverse effect of bringing for kettleman's physical and mental health because of ash discharge.Especially can guarantee deduster ash discharge effectively on time, prevent that dust is to the pollution of environment in the deduster.

Fig. 1 is the overall structure schematic diagram of mechanical actuation device in the utility model, and Fig. 2 is the structural representation of three pivot point levers among the embodiment two

Embodiment one: present embodiment is made up of control circuit and mechanical actuation device.Mechanical actuation device is made up of casing 3, electromagnet 2, core iron 1, three pivot point levers 6, translation arms 10, back-moving spring 12, wedge 13.Electromagnet 2 is fixed on the fixed head 7, and fixed head 7 is fixed in the casing 3.Core iron 1 is set in the coil groove 14 of electromagnet 2, and a connecting rod 4 is fixed in core iron 1 lower end, and the other end of connecting rod 4 is fixed on the fulcrum 15 of three pivot point levers, 6 upper ends.Three pivot point levers are right angled triangle, and another fulcrum 16 of three pivot point levers, 6 upper ends is set on the fixed head 5 by axle, and fixed head 5 is fixed in the casing 3, and the lower fulcrum 17 of three pivot point levers 6 is set in the middle part of translation arms 10 by axle.Translation arms 10 is set in the chute 18 of support 8, be fixed with a fixed pulley 11 below the chute 18, the lower surface of translation arms 10 drop on fixed pulley 11 above, the upper end of support 8 is fixed on the outside of casing 3, fix a fixed pulley 9 on the rear end face of translation arms 10, back-moving spring 12 is connected between the lower end of the front end of translation arms 10 and support 8.Wedge 13 be fixed on deduster ash-draining gate 19 below.

Control circuit has the hand push button formula, as long as press start button, control circuit is just given electromagnet-signal of telecommunication, electromagnet has the electricity back to inhale moving core iron, and drivening rod moves up, and connecting rod spurs three pivot point levers and rotates, and affects the translation arms reach, ash-draining gate falls open automatically for gravity, and dust is got rid of.After opening certain hour, control circuit disconnects the power supply of electromagnet again, because the gravity of machineries such as core iron and the pulling force of back-moving spring move translation arms backward, promotes wedge 13 by fixed pulley 9 to the greatest extent, and ash-draining gate is closed.Control circuit also has the function of self-timing, and promptly control circuit is given electromagnetism Tie Tong certain hour electricity behind the certain hour, and outage goes round and begins again then, reaches the purpose of automatic removing dust.

Embodiment two: the difference of present embodiment and embodiment one is the shape of three pivot point levers 6, and three pivot point levers 6 of present embodiment are for L shaped.Other composition is identical with embodiment one with shape.
