Description

Technical Field

[0001] The invention relates to the technical field of gypsum model drying, in particular to a multi-stage temperature control drying device for preparing high-strength gypsum models. Background Art

[0002] The multi-stage temperature control drying device for preparing high-strength gypsum models is a device used in the drying process of gypsum products. It helps gypsum achieve the best drying effect at different stages by accurately controlling temperature changes, thereby maintaining its strength and shape. High-strength gypsum is usually suitable for construction, decoration, industrial products and other fields. This type of gypsum model requires special temperature control during the drying process to avoid the gypsum surface from drying out too quickly or the internal moisture from not completely volatilizing. The multi-stage temperature control drying device for preparing high-strength gypsum models ensures uniform evaporation of moisture during the gypsum drying process by gradually increasing temperature and humidity control, thereby avoiding the influence of excessively high temperature on the strength of the gypsum.

As the temperature inside the shell increases, the alloy wire made of nickel-titanium alloy shrinks due to heat, and the alloy wire shrinks to pull the connected cross-link to slide along the connection of the sub-duct, so that the cross-link is The hinged column on the connecting rod pushes the offset slot piece, and at this time the offset slot piece drives the connected output connecting pipe to flip, and the square slot block is staggered with the square slot opened on the bottom surface of the branch air duct by flipping the air duct guide plate, and the fan in the ventilation hood rotates, so that the fan guides the wind blown downward into the branch air duct through the wind gathering ring in the bellows, and allows the wind in the branch air duct to enter between the air duct guide plates through the square slot, and is heated by the electric heating pipe through the side of the air duct guide plate and enters between the placement plates, so that the hot air is blown through the side of the gypsum model, and the hot air passing between the placement plates is blown downward by the fan and passes through the placement plates, thereby increasing the heated area of ​​the outer surface of the gypsum model.

[0020] Working principle: Place the plaster model to be dried on the placement plate 54, then close the door panel 2, at this time the door panel 2 flips around the outer shell 1, and let the door panel 2 push the long slot rod 511 through the connected hinge block 512, and then the short rod seat 510 is pushed by the long slot rod 511, so that the placement plate 54 on the top side is pushed into the interior from the front side of the outer shell 1 and the door panel 2 is locked. At this time, the built-in temperature sensor and humidity sensor transmit the temperature and humidity data inside the outer shell 1 to the control module, and the control module controls the operation of the electric heating tube 53, and adjusts the power of the electric heating tube 53 to ensure that the internal environment of the outer shell 1 is within the normal temperature range. When the door panel 2 is unlocked, the elastic spring connected to the spring solid block 58 releases the elastic force to push the connected spring pressure rod 57 to pop out along the bottom of the bellows 56 to push the door panel 2 to open, and the door panel 2 is connected around the outer shell 1 through the door panel 2 When the door panel 2 is turned over, the connected hinge block 512 is driven to move, and the connected long slot rod 511 is pulled by the movement of the hinge block 512, so that the long slot rod 511 slides along the short rod seat 510. When the short rod seat 510 moves to the end of the long slot rod 511, the long slot rod 511 will pull the short rod seat 510, so that the short rod seat 510 drives the connected placement plate 54 and the inner pipe frame 55 to move. As the door panel 2 continues to turn over, the placement plate 54 slides outward along the inner side of the transverse slot frame 52, so that the plaster model located inside the shell 1 on the placement plate 54 is taken out from the inside. The placement plate 54 is cleverly driven to slide out of the shell 1 along the transverse slot frame 52 through the turning of the door panel 2, which is convenient for placing the plaster model located deeper inside the shell 1. At the same time, the sliding structure of the placement plate 54 and the transverse slot frame 52 can dissipate the heat around the plaster model more quickly after the plaster model is dried. When the electric heating tube 53 enters the working state, the temperature inside the shell 1 is relatively low. As the temperature inside the shell 1 increases, the alloy wire 611 made of nickel-titanium alloy shrinks due to the heat. The shrinkage of the alloy wire 611 pulls the connected horizontal connecting rod 66 to slide along the connection with the branch air duct 62, so that the hinge column 610 on the horizontal connecting rod 66 pushes the offset slot piece 69. At this time, the offset slot piece 69 drives the connected output connecting pipe 76 to flip, and the square slot block 68 is staggered with the square slot 65 opened on the bottom surface of the branch air duct 62 through the flip of the air duct guide plate 67. The fan 61 in the ventilation cover 4 rotates, so that the fan 61 guides the wind blown downward through the wind gathering ring 63 in the bellows 56 into the branch air duct 62, and allows the wind in the branch air duct 62 to pass through the square slot 65 and enter between the air duct guide plates 67, and pass through the side of the air duct guide plate 67 The electric heating tube 53 heats and enters between the placement plates 54, allowing the hot air to blow through the side of the gypsum model. The hot air passing through the placement plates 54 is blown downward by the fan 61 and passes through the placement plates 54, thereby increasing the heated area of ​​the outer surface of the gypsum model, improving the evaporation efficiency of the water in the gypsum, and ensuring that the gypsum models placed on each layer of the placement plates 54 are fully dried. When the drying is completed, the electric heating tube 53 and the fan 61 stop working, and the internal temperature of the shell 1 is reduced by natural cooling. The alloy wire 611 made of nickel-titanium alloy is reset after cooling, pushing the horizontal connecting rod 66 to flip the air duct guide plate 67. By flipping, the square groove block 68 connected to the air duct guide plate 67 blocks the square groove 65, leaving part of the heat between the air duct guide plate 67 and the water tank 8, reducing air circulation, so that subsequent drying can be preheated in advance; When the door panel 2 is closed and the spring pressure rod 57 is squeezed, the spring pressure rod 57 pushes the elastic spring to compress and press the downward moving cross frame 71 and squeeze the reciprocating spring, so that the downward moving cross frame 71 pushes the connected vertical column rod 72 to move downward along the connection of the horizontal plate 9, and the movement of the downward moving cross frame 71 pushes the connected plug strip 73 to press the trapezoidal block 713 on the plug-in tube 79, so that the trapezoidal block 713 is pressed to push the plug-in tube 79 to be inserted into the connecting tube 74 for automatic sealing, and after the door panel 2 is unlocked and locked, the spring pressure rod 57 is reset to automatically release the plug-in tube 79 and the connecting tube The connection of 74 is realized by rapid disassembly. The water in the water tank 8 is transported to the connecting pipe 74 through the input connecting pipe 75 by the water pump connected to the input connecting pipe 75. Then, the water in the water tank 8 is transported to the connecting pipe 74 through the connecting pipe 74 through the plug-in pipe 79. The water in the inner tube rack 55 absorbs the surrounding heat and transfers the heat to the placement plate 54 through contact. The bottom of the plaster model is dried by the placement plate 54, and the water filled in the inner tube rack 55 absorbs the surrounding excess heat to reduce heat loss. As the temperature inside the shell 1 rises, the alloy wire 6 made of nickel-titanium alloy As the temperature rises, the horizontal connecting rod 66 gradually contracts and moves, and the horizontal connecting rod 66 moves and drives the connected vertical folding rod 77 to move, so that the vertical folding rod 77 drives the push rod 78 to push the sliding block 711. At this time, the sliding block 711 slides along the inside of the valve block 710, so that the through hole 712 on the sliding block 711 is staggered with the input connecting pipe 75 connected to the valve block 710. At this time, the water in the inner pipe rack 55 collects part of the heat, and the sliding block 711 blocks the water in the inner pipe rack 55 from flowing back to the water tank 8 through the output connecting pipe 76, so that the water pump stops working, which can reduce In order to reduce the capacity loss caused by the continuous operation of the water pump, the alloy wire 611 made of nickel-titanium alloy is reset after cooling, and the horizontal connecting rod 66 drives the vertical folding rod 77 to reset, so that the vertical folding rod 77 pulls the sliding block 711 to connect the through hole 712 with the input connecting pipe 75, so that the water in the inner pipe rack 55 flows back to the bottom part of the water tank 8 through the output connecting pipe 76 under the action of gravity. The collected water is used for subsequent drying. The water pump passes the water with retained heat in the water tank 8 into the inner pipe rack 55 to preheat the inside of the outer shell 1, thereby reducing heat consumption, improving heat utilization, and reducing energy consumption.
