Description
Technical Field
The invention belongs to the field of drying furnaces, and particularly relates to a self-adjusting drying furnace with good sealing performance.
Background
At present, due to the requirement of factory processing, a drying furnace is used by more and more manufacturers, heat is transferred to materials through high temperature in the drying process, so that moisture in the materials is separated from the materials, evaporated water vapor is discharged, and the drying purpose is finally achieved.
The furnace gate of most traditional drying furnaces is simply articulated on the lateral wall of furnace body, because be hard contact between furnace gate and the furnace body, therefore the contact department of furnace gate and furnace body often has the existence of gap, heat in the furnace body takes place to leak from the gap easily, thermal loss leads to the inside temperature of furnace body to be difficult to reach the setting value easily, then treat that dry product just is difficult to reach specified drying degree, cause great influence to product quality easily, and, because the leakproofness of most traditional furnace gates is limited, therefore the temperature that is close to the seal department in the furnace body then is on the low side, temperature difference in the furnace body makes easily treating dry product and is heated inhomogeneously, the degree of drying that leads to each position of whole product is different, the production of the situation of local quilt overheat can appear even.
Therefore, we propose a self-adjusting drying oven with better sealing performance to solve the above problems.
Disclosure of Invention
The invention aims to provide a self-adjusting drying furnace with good sealing performance, which can uniformly heat a product to be dried and aims to solve the problem that most of the traditional drying furnaces have limited sealing performance.
In order to achieve the purpose, the invention adopts the following technical scheme: a self-adjusting drying furnace with better sealing performance comprises a furnace body and a furnace door hinged on the side wall of the furnace body, wherein the upper end and the lower end of the inner side wall of the furnace door are fixedly connected with fixed pins, the upper end and the lower end of the inner side wall of the furnace body are respectively provided with a sealing groove, the sealing grooves are arranged in one-to-one correspondence with the fixed pins, a notch of each sealing groove is respectively and hermetically connected with a flexible layer, electrorheological fluid is contained between the flexible layer and the bottom of the sealing groove, the inner top surface of the furnace body is inwards sunken to form a plurality of mounting grooves, the bottom of each mounting groove is fixedly embedded with a conductive strip, a rotating shaft internally provided with a thermoelectric generator is rotatably connected at the notch of each mounting groove, a plurality of evenly-arranged grabs are fixedly connected on the peripheral side wall of each rotating shaft, and the cold ends, the utility model discloses a furnace body, including furnace body, flexible layer, thermoelectric generator in pivot, the furnace body is equipped with the inside storage chamber that contains mercury in the lateral wall on the furnace body, the upper end of storage chamber is fixed to be communicated with the pipe that sets up of slope, every the busbar all extends to the intraductal setting, mercury and the intraformational electrorheological fluids of flexibility in the storage chamber pass through wire coupling connection, and a plurality of thermoelectric generator in the pivot connects in parallel on the route of mercury and electrorheological fluids through a plurality of busbars respectively.
The invention has the beneficial effects that:
when treating dry product and carrying out the drying, the furnace gate is in the closed condition, inlays the fixed pin of establishing in the seal groove on the furnace gate this moment and can be wrapped up by the flexible layer, and the laminating can make the fixed pin firmly joint in the seal groove at the flexible layer on fixed pin surface.
When the inside temperature of furnace body risees, the polylith paddle that is located on the pivot lower extreme lateral wall can be heated and take place deformation, the air that its periphery can be drawn to the in-process of deformation drives whole pivot and rotates, the temperature that rotates the inside paddle of mounting groove reduces then can resume to straight state, and rotate the inside paddle of furnace body then can be heated and take place deformation and draw the air and drive the pivot and rotate, the paddle that draws can not only form the vortex to the air in the furnace body, make hot-air can carry out more abundant contact with the product, promote dry going on, the cold junction and the hot junction of paddle tip also can make the continuous electric energy that produces of thermoelectric generator in the pivot.
When the temperature in the furnace body constantly rises, the mercury in the liquid storage cavity can gradually expand, because the guide pipe is obliquely arranged, the expanded mercury can be communicated with the thermoelectric generators in the plurality of rotating shafts sequentially through the conducting bars, when the mercury is communicated with the thermoelectric generators, the electrorheological fluid in the sealing groove can be conducted, the larger the voltage of the conducting current is, the larger the viscosity of the electrorheological fluid is, the stronger the fixing and clamping effects on the fixing pins are, and the dissipation of heat in the furnace body can be effectively avoided.
In the self-adjusting drying furnace with better sealing performance, the sealing layer is fixedly arranged at the edge of the inner side wall of the furnace door, and the sealing layer can ensure the sealing performance of the contact part of the furnace door and the furnace body and prevent the heat loss in the furnace body.
In foretell better self-interacting drying furnace of sealing performance, every the equal fixedly connected with triangle block of tip of fixed pin, triangle block can not only make the fixed pin insert more easily in the seal groove by flexible layer parcel, and can prevent that the fixed pin breaks away from in the seal groove easily.
In the self-adjusting drying furnace with better sealing performance, the upper port of the storage cavity is flush with the bottoms of the mounting grooves.
When the mercury in the liquid storage tank is heated and expanded, the expansion degree of the mercury is different at different temperatures, the expanded mercury can be communicated with more thermoelectric generators at higher temperatures, and the upper port of the storage cavity is flush with the bottoms of the mounting grooves, so that the mercury and the thermoelectric generators are in an open circuit state in a normal state.
In the self-adjusting drying furnace with better sealing performance, a cavity is arranged in the furnace door, a sliding plate which is vertically arranged is connected in the cavity in a sealing and sliding mode, a plurality of memory springs are fixedly connected between the sliding plate and the side wall of the cavity close to one end of the furnace body, and a communicating hole is formed in the side wall of the cavity close to one end of the furnace body.
When the inside temperature of furnace body is higher, memory spring can be heated the shrink, promotes the sliding plate and slides to the direction that is close to the furnace body in the cavity, and the atmospheric pressure in the space of keeping away from furnace body one end in the cavity can reduce, and the atmospheric pressure reduces then heat conduction rate will greatly fall, can effectively prevent heat conduction to the outside handle of furnace gate, the danger of handle scalding operating personnel's hand when avoiding opening the door.
The gas in the space near one end of the furnace body can be discharged into the furnace body through the communicating holes, so that the air pressure inside the furnace body is increased, the air pressure is increased, the heat conduction efficiency can be improved, a certain heat preservation effect can be realized on the furnace body, and the heat leakage is further avoided.
