Abstract

The utility model discloses a gas producer. A grate is fixed on an ash tray by a bolt, a tray is fixedly connected on the lower part of the ash tray, the tray is fixed on the upper end of an upright shaft, the middle lower part of the upright shaft is extended out of the furnace and the bottom is fixed with a gearwheel, the middle of the upright shaft is respectively provided with an upper and lower self-aligning bearings, and a pressure bearing for bearing the total weight in the furnace is provided between the upper and lower self-aligning bearings. The pressure bearing is fixed in a bearing case, the bearing case is fixed on the outer shell of the bottom of the furnace, the outer shell of the bottom of the furnace is also fixedly provided with a worm reducer, and the transmitting gear of the worm reducer is clutched and transmitted with the gearwheel of the lower end of the upright shaft. By adopting the rotatable transmission of non slideway, the working environment is improved, the transmission resistance is small not easy to be damaged, and the service life of the device is prolonged, for the convenience of exhausting the slag and operation.

Description

A kind of producer gas generator

Technical field:

The utility model relates to a kind of producer gas generator that utilizes coal to prepare water-gas.

Background technology:

Chemical industry or city centralizedly supply coal gas, employed producer gas generator utilize coal burning and saturated steam to react to prepare coal gas.In its production process, fire grate and ash-pan in the producer gas generator commonly used at present are to rotate with certain speed, fire grate is fixed by bolts on the ash-pan, there are upper support ring and master wheel in the ash-pan bottom with bolting equally, the upper support ring is placed on the lower support ring, has an annular slide track on upper and lower support ring, is placed with many steel balls in slideway, form a rolling bearing, can rotate mutually between the upper and lower like this support ring.The lower support ring is fixed on the furnace bottom and maintains static, during work, driving master wheel by reducer of turbodrill rotates, because master wheel, ash-pan, support ring, fire grate hold together up and down, like this, fire grate, ash-pan, upper support ring will rotate at a slow speed, under the effect of ash plough, slag are arranged ash bin automatically.Work because master wheel, upper and lower support ring and the steel ball of rotary actuator are in stove under 200-300 ℃ the high temperature for a long time, environment is abominable, strength degradation, and the corrosion of obnoxious flavour in addition causes work-ing life short; Often because the grey rotary resistance of collection increases in the upper and lower support ring, energy consumption is bigger, and it is serious to damage parts, and maintenance capacity is big.China Patent No. is 972291822 and is called a kind of coal briquette producer, it is the upper end that ash-pan is fixed on vertical shaft with a coupling device, it is outer and overlap head bearing that the lower end of vertical shaft reaches stove, bearing external application bracket is embraced and is fixed on the ground, bottom at vertical shaft is fixed with master wheel, reducer of turbodrill and master wheel interlock transmission.Though such structure has been set to rotatable parts outside the stove, drive disk assembly is on the ground, not only influences the discharging of slag, and dust fall also enters rolling bearing and gear easily, often breaks down.

The utility model content:

The purpose of this utility model provides a kind of rotation driving part and works at normal temperatures, and the transmission resistance is little, and not fragile, ash discharge is producer gas generator easily.

The purpose of this utility model is to realize like this, adopt bolt that fire grate is fixed on the ash-pan, be fixedly connected with pallet in the ash-pan bottom, pallet is fixed on the upper end of vertical shaft, the middle and lower part of vertical shaft is stretched out outside the stove and in the bottom and is fixed with master wheel, the middle part of vertical shaft is provided with respectively, following self-aligning bearing, on, the pressure bearing that bears all wts in the stove is equipped with in the centre of following self-aligning bearing, pressure bearing is fixed in the plumer block, plumer block is fixed on the furnace bottom shell, also fixedly mounted a reducer of turbodrill on the furnace bottom shell, the master wheel interlock transmission of the revolving gear of reducer of turbodrill and vertical shaft lower end.

Like this, rotation driving part in the coal-gas producer all is in outside the furnace shell, adopt no slideway rotation transmission, improved Working environment, the transmission resistance is little not fragile, has prolonged the work-ing life of equipment, has reduced maintenance cost, the space of bottom of furnace body is bigger simultaneously, is convenient to discharge slag and operation.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

As shown in Figure 1, the utility model comprises: collector 1, furnace roof 2, body of heater 3, fire grate 4, water jacket 5, ash-pan 6, pallet 7, plumer block 8, grey storehouse shell 9, bellows 10, furnace bottom shell 11, lime-ash case 12, bracing frame 13, master wheel 14, reducer of turbodrill 15, vertical shaft 16, fire grate 4 tops are used to add coal fuel, bellows 10 are used for even air feed in stove, water jacket 5 is used for the body of heater cooling, and lime-ash case 12 is used to store lime-ash.It adopts bolt that fire grate 4 is fixed on the ash-pan 6, be fixedly connected with pallet 7 in ash-pan 6 bottoms, the pallet bottom is provided with axis hole, utilize axis hole pallet 7 to be fixed on the upper end of vertical shaft 16, the middle and lower part of vertical shaft 16 is stretched out and is fixed with master wheel 14 outside the stove and in the bottom, the middle part of vertical shaft 16 is respectively arranged with, following self-aligning bearing 17, on, following self-aligning bearing is used to adjust and the fixing orientation of vertical shaft, on, the pressure bearing 18 that bears all wts in the stove is equipped with in the centre of following self-aligning bearing, pressure bearing 18 is fixed in the plumer block 8, plumer block 8 is fixed on the furnace bottom shell 11, furnace bottom shell 11 is supported by bracing frame 13, also fixedly mounted a reducer of turbodrill 15 on the furnace bottom shell 11, the master wheel 14 interlock transmissions of the revolving gear of reducer of turbodrill 15 and vertical shaft 16 lower ends.

Specification size of the present utility model can be made series product according to the preparation amount reasonable disposition of water-gas.
