[0003] In the existing dryers, the storage can only rely on its own sealing. It is impossible to determine whether the air inside is the best drying temperature for different materials. It is necessary to regulate the overall heating and cooling of the device itself. The dryer itself will affect the efficiency of heat conduction. Summary of the invention

[0004] The object of the present invention is to provide a drying device for high borosilicate material with a temperature self-regulating function to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: A drying device with temperature self-regulation function for high borosilicate material comprises a base frame, a drying furnace, a switch valve, a connecting pipe, a mounting frame, a servo motor and a temperature regulating mechanism, the base frame is fixedly connected to the drying furnace, the mounting frame and the temperature regulating mechanism, the drying furnace is fixedly connected to the switch valve, the switch valve is fixedly connected to the connecting pipe, the connecting pipe is fixedly connected to the temperature regulating mechanism, the drying furnace is connected to the servo motor through an electrical signal, the mounting frame is fixedly connected to the servo motor, and the output end of the servo motor is transmission-connected to the temperature regulating mechanism.

[0006] The present invention is used for drying wet materials. The wet materials are placed in a drying furnace, and a switch valve is opened. Low-pressure steam in a temperature regulating mechanism is passed into the drying furnace through a connecting pipe and the switch valve. The low-pressure steam puts the materials in a vacuum state in the drying furnace. The steam pressure drops so that the moisture on the surface of the materials reaches a saturated state and evaporates. The temperature inside the drying furnace is detected and fed back to a servo motor. The servo motor outputs torque to the temperature regulating mechanism. The temperature regulating mechanism performs temperature compensation so that the inside of the drying furnace always maintains an optimal temperature.

[0007] Furthermore, the drying furnace includes a furnace body, a bottom plate, a furnace cover and a temperature measuring mechanism. The furnace body is fixedly connected to the base frame, and the bottom plate and the furnace cover are in contact with the furnace body. The furnace body is provided with side holes and bottom holes. The side holes and the bottom holes are both arranged on the side wall of the furnace body close to the switch valve. The side holes are arranged below the bottom plate. The side holes are fixedly connected to the temperature measuring mechanism. The bottom holes are arranged below the side holes. The side holes are fixedly connected to the switch valve. A plurality of groups of air guide holes are arranged on the bottom plate. The plurality of groups of air guide holes are evenly distributed along the circular surface of the bottom plate. The bottom of the furnace body and the bottom plate together form an air cavity. The top of the furnace body, the bottom plate and the furnace cover together form a drying chamber. The temperature measuring mechanism is connected to the servo motor through electrical signals.

[0008] The wet material is placed on the bottom plate, and low-pressure steam enters the air cavity from the bottom hole and enters the drying chamber through the air guide hole, so that the moisture on the surface of the material reaches a saturated state and evaporates. The temperature measuring mechanism detects the gas temperature in the air cavity and feeds back an electrical signal to the servo motor.

[0009] Furthermore, the temperature measuring mechanism includes an outer tube, an inner tube, an inner tube, a spring rod, an orifice plate, a bottom tube and a pressure sensor.

[0010] The temperature of the gas in the air cavity changes, and heat is transferred to the inner tube. The gas in the inner tube expands when heated and contracts when cooled. When the gas expands when heated, it pushes the inner tube away in the direction close to the bottom tube. The spring rod squeezes the pressure sensor to feedback the electrical signal to the servo motor. When the temperature rises to a certain level, the air holes on the inner tube are no longer blocked by the inner tube, and the gas in the inner tube leaks out from the air holes. The external air is replenished into the inner tube through the bottom tube and the orifice plate, and the inner tube is reset under the action of the spring rod.

[0012] The cold air pipe inputs cold air into the inner cavity through the cold air hole, and the hot air pipe inputs hot air into the inner cavity through the hot air hole. The cold air and hot air are mixed in the inner cavity. The servo motor outputs torque to the bevel gear set according to the electrical signal feedback from the pressure sensor, and transmits torque to the air regulating mechanism through the bevel gear set to change the rate at which the air regulating mechanism mixes the cold and hot gases. When the mixed gas output rate is constant, by changing the mixing rate of the cold and hot gases, as well as the duration of different mixing rates, mixed gases of different temperatures can be accurately output to compensate for the temperature in the drying furnace.

[0013] Furthermore, the air regulating mechanism includes an air mixing cylinder, a top cover, a cold air fan, a first tooth head rod, a hot air fan and a second tooth head rod. The air mixing cylinder and the top cover are fixedly connected to the inner cavity, the first tooth head rod and the second tooth head rod are both engaged with the tooth surface of the main gear, the top cover is provided with a first top hole and a second top hole, the first top hole is rotatably connected to the first tooth head rod, the second top hole is rotatably connected to the second tooth head rod, the first tooth head rod is fixedly connected to the cold air fan, the second tooth head rod is fixedly connected to the hot air fan, and the air mixing cylinder is provided with an air outlet hole, which is arranged on the side wall of the air mixing cylinder close to the air mixing hole.

[0014] The servo motor outputs torque to the bevel gear set, and the bevel gear set drives the main gear to mesh with the tooth surfaces of the first gear head rod and the second gear head rod to transmit torque. The cold air fan and the hot air fan rotate around the axes of the first gear head rod and the second gear head rod respectively.

The hot air fan includes a second side plate, a third semicircular plate, and a fourth semicircular plate. The second side plate is fixedly connected to the third semicircular plate and the fourth semicircular plate. The third semicircular plate is fixedly connected to the second tooth head rod.

[0016] Cold air enters the sealed space between the inner cavity and the first side plate through the cold air hole, sinks through the second semicircular plate and enters the space between the first side plate and the second side plate, hot air enters the space between the inner cavity and the second side plate through the hot air hole, rises through the third semicircular plate and enters between the first side plate and the second side plate, and the cold air and hot air are mixed.

[0017] Furthermore, a first circuit is provided on the first semicircular plate, and the first circuit is provided on a side of the first semicircular plate close to the first side plate; a first one-way passage is provided on the second semicircular plate, and the first one-way passage is provided on a side of the second semicircular plate close to the first side plate; Initial state: the first side plate is perpendicular to the vertical central section of the shell, and the first semicircular plate is located on the side of the cold air fan away from the cold air pipe.

[0018] In the initial state, the cold air sinks through the first one-way passage on the second semicircular plate and can quickly enter between the first side plate and the second side plate. When the cold air fan rotates 180 degrees, the cold air sinks and cannot pass through the first one-way passage. As the cold air settles, it enters between the first side plate and the second side plate through the first circuit on the first semicircular plate. At this time, the rate of cold air entering per unit time becomes slower.

[0019] Furthermore, a second one-way passage is provided on the third semicircular plate, and the second one-way passage is provided on a side of the third semicircular plate close to the second side plate; a second loop is provided on the fourth semicircular plate, and the second loop is provided on a side of the fourth semicircular plate close to the second side plate; Initial state: the second side plate is perpendicular to the vertical central section of the shell, and the third semicircular plate is located on the side of the hot air fan away from the hot air pipe.

[0020] In the initial state, the hot air floats up and cannot pass through the second one-way passage. As the hot air increases, it contacts the fourth semicircular plate and is passed into the space between the first side plate and the second side plate through the second circuit.

As the hot air increases, it contacts the fourth semicircular plate and is introduced through the second circuit. When the cold air fan and the hot air fan rotate 180 degrees at the same time, the cold air sinks and cannot pass through. As the cold air settles, it is introduced through the first circuit on the first semicircular plate. At this time, the rate of cold air introduction per unit time becomes slower, and the hot air floats up and is directly introduced through the second one-way passage, and the rate of hot air introduction per unit time becomes faster; that is, the cold air is introduced quickly and the hot air is slow in the initial state, and the cold air is introduced slowly and the hot air is introduced quickly after rotating 180 degrees. The temperature of the mixed gas introduced into the drying furnace is adjusted by the time proportion of the initial state and the state of rotating 180 degrees. The present invention can monitor the temperature inside the drying furnace at all times through a temperature measuring mechanism, and when the temperature is lower than or higher than the optimal drying temperature, an electrical signal is fed back to compensate the temperature of the drying furnace by changing the temperature of the mixed gas introduced into the drying furnace.

[0027] like Figure 2 As shown, the drying furnace 2 includes a furnace body 21, a bottom plate 22, a furnace cover 23 and a temperature measuring mechanism 24. The furnace body 21 is fixedly connected to the base frame 1, and the bottom plate 22 and the furnace cover 23 are both in contact with the furnace body 21.

The plurality of groups of air guide holes 221 are evenly distributed along the circular surface of the bottom plate 22. The bottom of the furnace body 21 and the bottom plate 22 are enclosed to form an air cavity 25. The top of the furnace body 21, the bottom plate 22 and the furnace cover 23 are enclosed to form a drying chamber 26.

[0030] The temperature of the gas in the air cavity 25 changes, and heat is transferred to the inner tube 242. The gas in the inner tube 242 expands when heated and contracts when cooled.

[0035] like Figure 6 , Figure 7 , Figure 8 As shown, the cold air fan 743 includes a first side plate 7431, a first semicircular plate 7432, and a second semicircular plate 7433. The first side plate 7431 is fixedly connected to the first semicircular plate 7432 and the second semicircular plate 7433. The first semicircular plate 7432 is fixedly connected to the first tooth head rod 744. The hot air fan 745 includes a second side plate 7451, a third semicircular plate 7452, and a fourth semicircular plate 7453. The second side plate 7451 is fixedly connected to the third semicircular plate 7452 and the fourth semicircular plate 7453. The third semicircular plate 7452 is fixedly connected to the second tooth head rod 746.

[0036] The cold air passes through the cold air hole 733 into the sealed space between the inner cavity 731 and the first side plate 7431, sinks through the second semicircular plate 7433 into the space between the first side plate 7431 and the second side plate 7451, and the hot air enters the space between the inner cavity 731 and the second side plate 7451 through the hot air hole 734, rises through the third semicircular plate 7452 into the space between the first side plate 7431 and the second side plate 7451, and the cold air and the hot air are mixed.

[0037] like Figure 7As shown, the first semicircular plate 7432 is provided with a first loop 74321, which is provided on the first semicircular plate 7432 near the first side plate 7431, and the second semicircular plate 7433 is provided with a first one-way passage 74331, which is provided on the second semicircular plate 7433 near the first side plate 7431; Initial state: the first side plate 7431 is perpendicular to the vertical center section of the outer shell 73 , and the first semicircular plate 7432 is located on the side of the cold air fan 743 away from the cold air pipe 75 .

[0038] In the initial state, the cold air sinks through the first one-way passage 74331 on the second semicircular plate 7433 and can quickly enter between the first side plate 7431 and the second side plate 7451. When the cold air fan 743 rotates 180 degrees, the cold air sinks and cannot pass through the first one-way passage 74331. As the cold air settles, it enters between the first side plate 7431 and the second side plate 7451 through the first loop 74321 on the first semicircular plate 7432. At this time, the rate of cold air introduction per unit time becomes slower.

[0039] like Figure 8 As shown, the third semicircular plate 7452 is provided with a second one-way passage 74521, which is arranged on the side of the third semicircular plate 7452 close to the second side plate 7451, and the fourth semicircular plate 7453 is provided with a second loop 74531, which is arranged on the side of the fourth semicircular plate 7453 close to the second side plate 7451; Initial state: the second side plate 7451 is perpendicular to the vertical center section of the outer shell 73 , and the third semicircular plate 7452 is located on the side of the hot air fan 745 away from the hot air pipe 76 .

As the hot air increases, it contacts the fourth semicircular plate 7453 and passes into the space between the first side plate 7431 and the second side plate 7451 through the second loop 74531. When the hot air fan 745 rotates 180 degrees, the hot air floats up and passes directly into the space between the first side plate 7431 and the second side plate 7451 through the second one-way passage 74521.

After rotating 180 degrees, the cold air is introduced slowly and the hot air is introduced quickly. The temperature of the mixed gas introduced into the drying furnace 2 is adjusted by the time proportion of the initial state and the state of rotating 180 degrees.

[0041] The working principle of the present invention is as follows: the wet material is placed on the bottom plate 22, the switch valve 3 is opened, the low-pressure steam enters the air cavity 25 from the bottom hole 212, and enters the drying chamber 26 through the air guide hole 221. The low-pressure steam puts the material in a vacuum state in the drying furnace 2, so that the moisture on the surface of the material reaches a saturated state and evaporates, and the temperature inside the drying furnace 2 is detected. The servo motor 6 outputs torque to the bevel gear set 71 according to the electrical signal fed back by the pressure sensor 247. The bevel gear set 71 drives the main gear 72 to mesh with the first tooth head rod 744 and the second tooth head rod 746 to transmit torque. The cold air fan 743 and the hot air fan 745 rotate around the axes of the first tooth head rod 744 and the second tooth head rod 746 respectively. The cold air and the hot air enter the mixing cylinder 741 through the cold air fan 743 and the hot air fan 745 respectively. In the initial state, the cold air sinks through the first one-way passage 74331 on the second semicircular plate 7433 and can be quickly 74321 on the first semicircular plate 7432. At this time, the rate of cold air introduction per unit time becomes slower. In the initial state, the hot air floats up and cannot pass through the second one-way passage 74521. As the hot air increases, it contacts the fourth semicircular plate 7453 and enters through the second circuit 74531. When the hot air fan 745 rotates 180 degrees, the hot air floats up and enters directly through the second one-way passage 74521, and the rate of hot air introduction per unit time becomes faster. That is, in the initial state, the cold air is introduced quickly and the hot air is slow. After rotating 180 degrees, the cold air is introduced slowly and the hot air is fast. The temperature of the mixed gas introduced into the drying furnace 2 is adjusted by the time proportion of the two states. When the mixed gas output rate is constant, mixed gases of different temperatures can be accurately output to compensate for the temperature in the drying furnace 2.
