When the pressing plate 11 moves up and down along the first cavity 7, the toothed plate 20 is driven to move together, and due to the meshing of the toothed grooves on the toothed plate 20 and the rotating shaft 21, the rotating shaft 21 is driven to rotate in the process that the toothed plate 20 moves up and down, and the bevel gear set 22 is driven to rotate in the rotating process of the rotating shaft 21, so that the stirring blade 16 installed at the output end of the bevel gear set 22 rotates together with the output end of the bevel gear set 22, and the effect of driving the stirring blade 16 to rotate is achieved.
Referring to fig. 1, as an embodiment of the present invention, a tank 24 is fixedly installed on a top wall of a tank body 1, a storage battery 25 connected in series with a heating wire 3 is fixedly installed in the tank 24, a support rod 26 is vertically and fixedly installed on the top wall of the tank 24, a generator 27 connected in series with the storage battery 25 is fixedly installed on a top end of the support rod 26, and a fan blade 28 is fixedly installed on a driving shaft of the generator 27.
In cold winter, snowstorm weather frequently appears, the flabellum 28 is blown under the effect of strong wind, and the pivoted flabellum 28 drives the drive shaft rotation of generator 27 to generator 27 begins the electricity generation, because battery 25 and generator 27 establish ties, the electric energy that consequently generator 27 sent will charge for battery 25, thereby has reduced external power supply and has played resources are saved's effect for the power supply volume that battery 25 charges.
Referring to fig. 1, as an embodiment of the present invention, a first sleeve 29 and a second sleeve 30 are symmetrically and fixedly mounted on the inner and outer bottom walls of a cell body 1, a third magnet 31 is movably disposed in the first sleeve 29, a memory alloy 32 fixedly connected with the third magnet 31 is fixedly mounted on the top wall of the first sleeve 29, a second guide rod is vertically and fixedly mounted in the second sleeve 30, a portion of the second guide rod located above a second spring 34 is movably sleeved with a fourth magnet 33, the fourth magnet 33 and the third magnet 31 repel each other, a second spring 34 fixedly connected with the second sleeve 30 is vertically and fixedly mounted on the bottom wall of the fourth magnet 33, and a switch 35 connected in series with an electric heating wire 3 is fixedly mounted on the inner bottom wall of the second sleeve 30.
At the initial state, the internal temperature of the tank body 1 is low due to the low external temperature, so the memory alloy 32 contracts and drives the third magnet 31 to move to the top end of the first sleeve 29, and at this time, because the distance between the third magnet 31 and the fourth magnet 33 is long, the fourth magnet 33 will move to the top end of the second sleeve 30 under the action of the second spring 34, so the switch 35 will not be contacted, and the heating wire 3 will normally work.
When the interior of the tank body 1 is gradually heated, the temperature in the tank body 1 gradually rises, so the memory alloy 32 in a contraction state at a low temperature extends, and drives the third magnet 31 to move downwards along the inner wall of the first sleeve 29, at the moment, because the distance between the third magnet 31 and the second magnet 19 is gradually shortened, the repulsive force is gradually increased, because the force of the memory alloy 32 heated and extended is greater than the elastic force of the second spring 34, when the memory alloy 32 extends, the fourth magnet 33 gradually moves downwards along the second sleeve 30 and presses the switch 35, so the electric heating wire 3 is powered off, because the temperature in the tank body 1 can already ensure the fermentation rate, and the timely power off plays a role in saving resources.
The working principle is as follows: in cold winter, the ambient temperature is lower, so the temperature in the cell body 1 of the reaction cell is also very low, and in low temperature environment, the reaction rate of the raw materials in the reaction cell is reduced, at the moment, the electric heating wire 3 is started to heat the water in the water tank 2, and the steam is used to heat the raw materials in the cell body 1, so that the raw materials can be normally fermented.
In an initial state, under the action of the first spring 13, the pressing plate 11 will be at the bottom of the first cavity 7, and the blocking block 14 is inserted into the air outlet to block it under the action of gravity, at this time, after the water vapor enters the conduit 12 from the air inlet pipe 5, the water vapor will flow along the conduit 12 to the space below the pressing plate 11 in the first cavity 7, at this time, since the blocking block 14 blocks the air outlet, the water vapor will gather in the space, so that the pressure in the space gradually increases, after the pressure increases, the pressing plate 11 will be pushed to move upward along the guide rod 10, at this time, the first spring 13 is squeezed, since the water in the water tank 2 is continuously boiling, the water vapor will continuously flow into the space, so the pressing plate 11 continuously moves upward, when the pressing plate 11 moves up and down along the first cavity 7, the toothed plate 20 will move together with the up and down movement, since the toothed grooves on the toothed plate 20 and the rotating shaft 21 mesh, during the rotation of the rotating shaft 20, during the rotation of the rotating shaft 21, the bevel gear set 22 will be driven to rotate, so that the output end of the stirring cone 16 mounted on the output end of the gear set 22 rotates together with the stirring cone 16, thereby driving the stirring cone 16.
When steam enters the space below the pressure plate 11 in the first cavity 7 through the conduit 12, the pressure plate 11 moves upwards along the guide rod 10, in the process, the pressure plate 11 moves upwards along the thin rod 17, when the pressure plate 11 is in contact with the first magnet 18, the first magnet 18 is driven to move upwards, because in the initial state, the gravity of the first magnet 18, the thin rod 17 and the blocking piece 14 is equal to the attraction force between the first magnet 18 and the second magnet 19, at the moment when the pressure plate 11 drives the first magnet 18 to move upwards, the first magnet 18 and the second magnet 19 are attracted together, and therefore the blocking piece 14 is separated from the air outlet, so that the first spring 13 which is squeezed can push the pressure plate 11 downwards, so that water vapor in the space below the pressure plate 11 can be rapidly discharged, and in the process that the pressure plate 11 pushes the pressure plate 11 to move downwards, the pressure plate 11 firstly moves along the thin rod 17, so that in the process, the pressure plate 11 cannot be in contact with the blocking piece 14, so that the air outlet can be opened, in the process, the first spring 13 pushes the blocking plate 11 downwards, so that the first magnet 18 is pushed to completely, the whole stirring efficiency is changed, and the second magnet 18 is pulled upwards, and the stirring efficiency is changed.
Thereby make the vapor in the space that lies in clamp plate 11 below in the first cavity 7 can discharge in a period of time, vapor enters into behind the blast pipe 15 and takes place the heat exchange with blast pipe 15, then take place the heat exchange between blast pipe 15 and the microthermal raw materials, make the temperature of the raw materials around the blast pipe 15 rise, thereby make this part raw materials can normally ferment, and meanwhile, the clamp plate 11 will be promoted downwards fast by extruded first spring 13 in the steam by exhaust in-process, clamp plate 11 will move down along guide bar 10 this moment, under link gear's effect, stirring vane 16 reverses fast, thereby make the raw materials in the cell body 1 be heated evenly, the effect that has played the raw materials homoenergetic normal fermentation that makes in the cell body 1.
At the initial state, the internal temperature of the tank body 1 is low due to the low external temperature, so the memory alloy 32 contracts and drives the third magnet 31 to move to the top end of the first sleeve 29, and at this time, because the distance between the third magnet 31 and the fourth magnet 33 is long, the fourth magnet 33 will move to the top end of the second sleeve 30 under the action of the second spring 34, so the switch 35 will not be contacted, and the heating wire 3 will normally work.
When the interior of the tank body 1 is gradually heated, the temperature in the tank body 1 gradually rises, so the memory alloy 32 in a contraction state at a low temperature extends, and drives the third magnet 31 to move downwards along the inner wall of the first sleeve 29, at the moment, because the distance between the third magnet 31 and the second magnet 19 is gradually shortened, the repulsive force is gradually increased, because the force of the memory alloy 32 heated and extended is greater than the elastic force of the second spring 34, when the memory alloy 32 extends, the fourth magnet 33 gradually moves downwards along the second sleeve 30 and presses the switch 35, so the electric heating wire 3 is powered off, because the temperature in the tank body 1 can already ensure the fermentation rate, and the timely power off plays a role in saving resources.
Due to the large surface area of the spiral pipe 23, when the water vapor in the exhaust pipe 15 flows in the spiral pipe 23, the water vapor can be in contact with the spiral pipe 23 for a long time, and in the process of the contact of the water vapor and the spiral pipe 23, the heat in the water vapor can be transferred to the surface of the spiral pipe 23 through a heat exchange mode, so that the heat exchange can be carried out between the raw material in the tank body 1 through the spiral pipe 23, and the effect of enabling the temperature of the raw material to be increased is achieved.
In cold winter, snowstorm weather frequently appears, the flabellum 28 is blown under the effect of strong wind, and the pivoted flabellum 28 drives the drive shaft rotation of generator 27 to generator 27 begins the electricity generation, because battery 25 and generator 27 establish ties, the electric energy that consequently generator 27 sent will charge for battery 25, thereby has reduced external power supply and has played resources are saved's effect for the power supply volume that battery 25 charges.
