Definitions
- Apparatus for tearing up and stoking bales of straw material and for stoking other kinds of solid fuel is provided.
- This invention relates to apparatus for tearing up and sto ⁇ king of straw bales, and for automatic stoking of chips, pieces of wood, paper, industrial waste, garbage, lignite, coal, briquettes, pellets and other similar solid fuels.
- bales are torn up or cut to pieces in a so called bale cutter before the straw is fed into the furnace by a screw conveyor or a blower.
- bale cutters Several different types are known. Their main shortcomings are that they are sensitive to the earth and stone particles that follow the bales, and to the string that the bales are held together by.
- the o ' bjective of the invention is to point out a robust and reliable apparatus for tearing up and stoking straw bales, which is not sensitive to the earth and stone part- ticles or the string which is found in the bales. It should also be possible to use the apparatus for combustion of other kinds of solid fuel than straw bales.
- an appara ⁇ tus which comprises a number of parallel reciprocating or excentrically moved serrated rods, which are situated in connection with the feeding opening of the furnace, so that the fuel, which is fed from a magazine onto the rods, is conveyed into the furnace.
- the serrated rods can tear up the string and straw from the bottom, and carry it away during the reciprocating or excentric motion of the rods. Since the apparatus, in contrast to the known straw cutters, does not comprise any actual knives it is not sensitive to earth or stone particles or string.
- a suitable shape of the serrations is that the edge of the teeth is vertical on the forward side, while the rear side slopes downward towards the centre of the rods.
- the serrated rods can be extended into the furnace, so that they also serve as the grate of the fur ⁇ nace. It is, however, preferred that the apparatus is made as a separate unit, independent of the furnace.
- the fuel can be fed from the reciprocating or excentrically moved serrated rods into the furnace by an indermediate sliding ramp or screw conveyor, but it is convenient that the rods are located in direct connection with the feeding opening of the furnace, so that the fuel is fed directly onto the grate of the furnace.
- the serrated rods are attached to a common yoke that is driven by single propulsion unit. It is, however, obvious that the serrated rods can be moved individually, or in groups.
- the apparatus is preferrably designed so that the reciprocating or excentrical movement is imparted over a flywheel that is driven by a motor.
- the irregularities in the movement of the serrated rods which might occur as a consequence of uneven composition of the fuel is then compensated by the flywheel, and a smaller motor may be used.
- a grate can be positioned between them.
- the grate can be used for regulating the amount of fuel which is fed into the furnace, if it is arranged so that it can be raised or lowered in relation to the serrated rods. This is preferrably done by hinging the grate in the end that is closest to the feeding door. When the grate is raised the protuding area of the teeth decreases, and as a consequence they transport less material.
- the grate can also be used for achieving a smooth action of the serrated rods. If the fuel should contain some specially resistant material, the grate is raised, so that only a small part of the teeth protrude.
- the movement of the grate can be controlled in several ways.
- a suitable way is that the vertical movement of the grate is controlled in response to the load of the motor. At occasions when the load is high, that is when the fuel con ⁇ tains resistant material, the grate is raised accordingly. It is also suitable that the vertical movement of the grate is controlled in response to the load of the furnace. If the load is high, the grate is lowered, and the serrated rods convey a relatively large amount of fuel into the fur ⁇ nace. If, on the other hand, the load is small, the grate is raised, and only a small amount is transported.
- the apparatus in which the fuel is fed in separate charges, for example in the form of bales of straw or paper, can be arranged so that a room with a door is situated above the rods.
- the door can be opened to a horizontal position for receiving the fuel, and dumps the fuel into the room when it is closed.
- a horizontal movable fire damper At a level below the door is a horizontal movable fire damper, on which the fuel lies.
- the fire damper can be pulled out so that the fuel falls down onto the serrated rods.
- the opening of the door and the fire damper can be controlled in response to the negative pressure in the room, which shows that no burning back has occured in the material.
- figure 1 shows, diagrammatically, a furnace and the apparatus according to the invention seen from the side
- figure 2 shows a section through the bottom part of the apparatus
- figure 3 shows a section through one half of the apparatus along the line III-III in figure 2, seen from above,
- figure 4 shows a section through one half of the apparatus along the line IV-IV in figure 2
- figure 5 shows a plan of a furnace plant designed in accordance with the invention
- figure 6 shows, diagrammatically, embodiment of the apparatus in connection with a straw conveyor
- figure 7 shows, diagrammatically, a section through an embodiment of the apparatus with verti ⁇ cal excentrically moved rods
- figure 8 shows, diagrammatically, the rods seen from above, in solid lines when teeth are raised, and in broken lines when the teeth are lowered
- figure 9 shows, diagrammatically, the knives for cutting the strings of the bales.
- reference number 1 indicates an ordinary fur ⁇ nace and 2 indicates, generally, the apparatus for auto ⁇ matic comminuting and stoking of rectilinear large bales 3.
- the apparatus comprises a number of reciprocating rods 4, which are equipped with serrations 5 on the top.
- the ser ⁇ rated rods 4 are connected to a common yoke 6 which is driven by an electric motor 7 over a flywheel 8 and a con ⁇ nection rod 9.
- the rods 4 are connected to the yoke 6 by short rods 10 which slide in bushings 11 that are attached to a supporting frame.
- the opposite end of the rods 4 are also connected to a number of short rods 12, which in a corresponding way slide through bushing 13 that are attac ⁇ hed to the frame.
- the grate 14 is hinged 15 to the frame at the feeding opening 16.
- the opposite end of the grate is connected to a pneumatic or hydraulic cylinder 17 which can raise or lower the grate 14, so that larger or smaller parts of the teeth of the serrated rods 4 are exposed.
- the upper part of the room 18, above a horizontal fire damper 19, is called the feeding shaft 20.
- the damper which can be ex ⁇ tracted in a horizontal direction, devides the room in two parts and prevents burning-back in the fuel.
- the feeding shaft 20 is equipped with a shaft door 21, which can be swinged down to a horizontal positon in order to recive the fuel.
- a plan of a furnace plant is shown, whic prises a building 22 with two furnaces l',l", both of which are equipped with an apparatus as describe above.
- the room which contains the furnaces is called the sluice room 23.
- the storage building 24 for the fuel is situated at a distance from the building 22. From the storage building 24 an automatic crane 25 conveys the fuel to the building 22.
- the sluice room 23 is furnished with a fire door 26.
- the different functions are controlled by an automatic con ⁇ trol mechanism, which will not be described specifically and which can be made from standard components.
- a pressure trans ⁇ ducer is used for detecting the pressure in the feeding shaft, and the automatic crane and the fire door are controlled by icroswitches .
- the fire damper 19 closes and the negative pressure in the feeding chute 20 is ascertained.
- the fire door 26 opens and the automatically controlled crane 25 conveys a bale into the sluice room 23, whereupon the fire door 26 closes again. Wheen the fire door 26 is reported closed and the crane 25 is reported inside the sluice room 23, the shaft door 21 of the boiler which has "called" for the fuel opens, if there is still a negative pressure in the shaft 20 above the fire damper 19.
- the automatic crane 25 places the bale on top of the shaft door 21, whereupon the autmatic crane 25 returns to the position by the fire door 26.
- the shaft door 21 closes and the straw bale slides into the feeding shaft 20.
- the fire damper 19 opens and the straw bale slides down on top of the pre ⁇ ceding bale.
- the fire damper 19 starts to press against the bale, which causes the strings around the bale to break whereupon the damper 19 opens again.
- the bottom of the shaft is covered by several rows of the serrated rods 4, the reciprocating movement of which causes the straw to be torn up and conveyed into the furnace as it is burned up. Between the serrated rods 4 lies the grate 14. The grate moves, as has been mentioned earlier, up and down according to the current co sumption of the motor 7 and the fuel consumption, which depends on the load of the furnace .
- Figure 6 shows an embodiment in which the apparatus 1 accor ⁇ ding to the invention is connected to a straw conveyor 27.
- the apparatus is mounted vertically, and conveys the straw down to a screw 28 which transports it into the furnace.
- the described apparatus has the advan ⁇ tage that it can be used with different forms of solid fuel, separately or mixed. If no straw is available, one can with ⁇ out difficulties switch to another fuel, for example wood chips .
- FIG 7. The apparatus for automatic comminuting and stoking of straw bales com ⁇ prises a box 29 with an openable door 30, through which the straw bale 3 is lowered by the crane 25.
- One of the sides of the box 29 consists of a hydraulic ram 31, which pushes the straw bale 3 against the comminuting apparatus wich is attached to the other side of the box.
- the comminuting apparatus comprises a number of vertical serrated rods 4, which in both ends are excentrically connected to an axle, so that the rods move excentrically. All of the rods are moved at the same time, so that the straw is "raked” from the bale and carried downwards.
- the excentric motion should be larger than the distance between two adjacent teeth, so that the straw moves downward from tooth to tooth and is released from the teeth by the immobile rods 14.
- the serrated rods are arranged two by two with an immobile rod 14 between at a short distance.
- the straw is carried down into a screw conveyor 28, which conveys the straw into the furnace.
- the furnace is separated from the comminuting apparatus by a fire wall 33.
- the pressing force of a the hydraulic ram 31 is controlled by the current comsumption of the comminuting apparatus, so that the bale is always pushed against the serrated rods with a suitable force.
- the pressure is automatically released if the comminutor is too heavily loaded.
- the serrated rods can be equipped with a set of knives 34, which are attached to the slanted edge of the teeth of the rods .
