Description

Technical Field

[0001] This invention relates to the field of modified polymer material production equipment technology, specifically to a drying device and drying method for modified polymer materials. Background Technology

[0002] Modified polymer materials are produced by modifying polymeric materials (such as plastics, rubber, and fibers) through physical or chemical means, thereby endowing them with new or superior properties. They are widely used in various industries. Modification can improve the strength, toughness, heat resistance, corrosion resistance, and processability of materials, making them more adaptable to different environments. During the production process of modified polymer materials, the presence of liquids can affect their properties. Therefore, drying equipment is typically used to dry the modified polymer materials.

[0003] Conventional drying equipment involves placing modified polymer materials inside the equipment and blowing high-temperature gas onto their surface to achieve efficient drying. Typically, the modified polymer materials are placed on drying racks, and after drying, workers need to sequentially unload different layers of the modified polymer materials, resulting in low unloading efficiency. Furthermore, the drying process requires circulating high-temperature gas, and the heating device needs to heat each passing gas, increasing energy consumption. Therefore, we propose a drying device and method for modified polymer materials. Summary of the Invention

[0004] To address the shortcomings of existing drying devices and methods for modified polymer materials, this invention provides a drying device and method for modified polymer materials. The device features drying plates that drive the modified polymer materials through drying. After drying, a first chain is controlled to rotate, simultaneously tilting multiple sets of drying plates to ensure convenient unloading of the modified polymer materials, thus solving the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a drying device for modified polymer materials, comprising a lower chamber, an upper chamber mounted on the upper end of the lower chamber via a hydraulic rod, a heating box mounted in the middle of the interior of a control door, a heater mounted on the top of the heating box above the control door, a first transmission pipe mounted outside the heater, air outlet boxes mounted on both sides of the upper part of the upper chamber, a second transmission pipe mounted outside the air outlet boxes, a guide rail fixed at the bottom of the lower chamber, a bracket movably sleeved on the upper end of the guide rail, a first chain mounted on both sides of the bracket via a gear set, a drying plate mounted in the middle of the bracket via a rotating pin, a toothed plate horizontally fixed inside the bracket, a lead screw horizontally mounted inside the bracket, and a slider threaded onto the external thread of the lead screw.

[0006] Preferably, partition plates are installed on both sides of the upper housing, the partition plates are installed on both sides of the heating box, and a partition is installed at the lower end of the partition plates.

[0007] Preferably, the bracket is located at the lower end of the heating box, and heating nozzles are installed at equal intervals at the lower end of the heating box, while the heater is installed at the upper end of the upper box.

[0008] Preferably, two sets of the second transmission pipe are installed, and the two sides of the first transmission pipe are interconnected with the second transmission pipe. An air pump is installed inside the first transmission pipe.

[0009] Preferably, an absorbent sponge is installed inside the lower end of the second transmission pipe, and a drain nut is threaded onto the lower end of the second transmission pipe. The drain nut is installed at the lower end of the absorbent sponge, and the absorbent sponge is installed at the end of the first transmission pipe.

[0010] Preferably, a filter screen is installed inside the upper housing and on one side of the partition plate. The filter screen is installed at the lower end of the air outlet box, and the filter screen and the air outlet box are both provided with filter screens.

[0011] Preferably, the bracket is installed in the middle of the lower housing, and control doors are installed on both sides of the lower housing. The height of the bracket is lower than the overall height of the control doors.

[0012] Preferably, the gear set includes two sets of gears, one set of gears is sleeved inside the first chain, and the other set of gears is sleeved outside the second chain. A movable pin is fixed to the side of the first chain, and sliding grooves are opened inside both sides of the drying plate.

[0013] Preferably, a first gear and a second gear are movably mounted inside the slider. A stirring rod is fixed to one end of the second gear. The first gear and the second gear mesh with each other. The lower end of the first gear meshes with the toothed plate. The stirring rod is in contact with the upper end of the drying plate.

[0014] A drying method for a drying apparatus for modified polymer materials, the specific drying method comprising the following steps;

[0015] Step 1: Move the bracket out of the lower box and start the motor installed on the outside of the gear set. At the same time, control the rotation of the two sets of first chains to keep the drying plates in a parallel state. Meanwhile, spread the modified polymer material evenly on the upper part of the drying plates in sequence.

[0016] Step 2: Control the bracket to move inside the guide rail, open the control door, and move the control bracket to the middle of the lower box. At the same time, start the hydraulic rod, which will drive the upper box to close at the top of the lower box. Simultaneously close the control door to ensure that the lower and upper boxes are sealed. At the same time, the bracket moves to the center of the lower box.

[0017] Step 3: Start the heater. The heater heats the gas passing through it. The heated gas is evenly transmitted into the lower chamber through the heating box. The high-temperature gas heats and dries the modified polymer material. At the same time, the dried gas flows back into the second transmission pipe through the filter and the gas outlet box. Start the air pump. The air pump provides power for the gas flow. The heated gas circulates in the lower chamber, thus realizing the drying operation of the modified polymer material.

[0018] Step 4: The temperature inside the lower chamber is monitored by a temperature control device to ensure that the lower chamber maintains a constant temperature. At the same time, the drying gas is delivered to the inside of the second transmission pipe, where the water-absorbing sponge absorbs the moisture, and the filtered gas flows back to the inside of the lower chamber through the heating box.

[0019] Step 5: Start the lead screw. The lead screw and the slider move in a threaded motion, controlling the slider to move laterally left and right. At the same time, the slider drives the first gear to mesh with the lead screw. The first gear drives the second gear to rotate, and the second gear drives the stirring rod to rotate. The stirring rod stirs the modified polymer material placed on the upper part of the drying plate to ensure that the modified polymer material is fully mixed.

[0020] Step Six: Observe whether the modified polymer material is dry. After the modified polymer material is dry, push the support to control the support to be pushed out from the inside of the lower box. Start the motor installed on the outside of the gear set. The motor controls the rotation of the first chain. One set of the first chain drives one side of the drying plate to move upward through the movable pin, and the other set of the first chain drives the drying plate to move downward through the movable pin. That is, the drying plate is kept in an inclined state to ensure that the modified polymer material is quickly unloaded.

[0021] Compared with existing drying devices and methods for modified polymer materials, the present invention has the following advantages:

[0022] 1. The drying device and method for modified polymer materials, by starting an air pump, drives gas through a first transmission pipe to the interior of a heater. The heater heats the gas and then transports it through a heating chamber to the interior of a lower chamber, thereby drying the modified polymer material with heated gas. At the same time, the dried gas flows back through an outlet chamber to the interior of a second transmission pipe, which then transports the gas back to the interior of the first transmission pipe. Thus, the gas is kept in a circulating state in the lower chamber, ensuring gas circulation and reducing heat loss.

[0023] 2. The drying device and method for modified polymer materials involve placing the modified polymer material on the upper end of a drying plate. During the drying process, a lead screw is activated, causing a threaded motion between the lead screw and the slider, allowing the slider to move laterally. Simultaneously, the slider drives the first gear to mesh with the gear plate, which in turn drives the stirring rod to rotate via the second gear. The stirring rod maintains its rotation while moving laterally, thus stirring the modified polymer material on the upper end of the drying plate and ensuring the effective drying of the modified polymer material.

[0024] 3. The drying device and method for modified polymer materials involve drying the modified polymer materials by placing them on the upper part of a drying plate. After the modified polymer materials are dried, the support is pushed out of the lower housing, and the motor installed on the outside of the gear set is started. The motor drives the first chain to rotate synchronously via the second chain. The first chain drives the movable pin to push the two ends of the drying plate up and down, ensuring that one side of the drying plate is tilted downwards. This ensures that the modified polymer materials placed on the upper part of the drying plate can be unloaded simultaneously, ensuring the convenience and efficiency of unloading the modified polymer materials.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A drying device for modified polymer materials includes a lower chamber 1. An upper chamber 4 is mounted on the upper end of the lower chamber 1 via a hydraulic rod 3. Activating the hydraulic rod 3 moves the upper chamber 4 up and down, ensuring convenient access for subsequent maintenance of the upper chamber 4. A heating chamber 5 is installed in the middle of the control door 2. A heater 6 heats gas, which is then evenly heated and dried on the modified polymer material via the heating chamber 5. A heater 6 is also installed at the top of the heating chamber 5, above the control door 2. A first transmission pipe 7 is installed outside the heater 6, connecting to a second transmission pipe 11, allowing gas to be delivered to the interior of the heater 6 and heated before being transferred to the interior of the lower chamber 1. The upper box 4 has two air outlet boxes 10 installed on both sides of its upper part. A second transmission pipe 11 is installed on the outside of the air outlet box 10. A guide rail 15 is fixed at the bottom of the lower box 1. A bracket 16 is movably sleeved on the upper end of the guide rail 15. A first chain 17 is installed on both sides of the bracket 16 through a gear set 18. When the first chain 17 rotates, it drives the drying plate 21 to adjust its angle. The drying plate 21 is installed in the middle of the bracket 16 through a rotating pin 20. A toothed plate 24 is fixed horizontally inside the bracket 16. A first gear 27 meshes with the toothed plate 24, that is, the first gear 27 remains rotating when it moves horizontally. A lead screw 25 is installed horizontally inside the bracket 16. A slider 26 is installed on the external thread of the lead screw 25.

[0035] Please see Figure 4 The upper chamber 4 has partition plates 8 installed on both sides. The partition plates 8 are installed on both sides of the heating chamber 5, and the lower end of the partition plates 8 is equipped with a partition. By installing the partition plates 8 inside the upper chamber 4, the support 16 is moved between the two sets of partition plates 8, and the first transmission pipe 7 heats and dries the modified polymer material. The partition plates 8 limit the direction of gas flow, and the partition installed at the lower end of the partition plates 8 is movable to ensure that when the support 16 moves into the lower chamber 1, interference is avoided.

[0036] Please see Figure 4 The bracket 16 is set at the lower end of the heating box 5. Heating nozzles are installed at equal intervals at the lower end of the heating box 5. The heater 6 is installed at the upper end of the upper box 4 and is set at the lower end of the heating box 5 through the bracket 16. At the same time, heating nozzles are installed inside the heating box 5. After the gas passes through the heater 6, the heated gas is transported through the heating box 5 to the interior of the lower box 1, that is, the hot gas dries the modified polymer material placed there.

[0037] Please see Figure 2The second transmission pipe 11 is equipped with two sets. The two sides of the first transmission pipe 7 are interconnected with the second transmission pipe 11. An air pump 14 is installed inside the first transmission pipe 7. Through the interconnection between the first transmission pipe 7 and the second transmission pipe 11, hot air is transported to the inside of the second transmission pipe 11 through the air outlet box 10. At the same time, it flows back to the inside of the first transmission pipe 7 through the second transmission pipe 11. Then, the gas is transported to the inside of the heating box 5 through the first transmission pipe 7, ensuring that the heated gas inside the lower box 1 is kept in a circulating state and the heated gas is continuously circulated, reducing heat loss.

[0038] Please see Figure 3 The lower end of the second transmission pipe 11 is equipped with a water-absorbing sponge 12, and a drain nut 13 is threaded onto the lower end of the second transmission pipe 11. The drain nut 13 is installed at the lower end of the water-absorbing sponge 12, which is installed at the end of the first transmission pipe 7. The water-absorbing sponge 12 absorbs water molecules in the gas passing through the second transmission pipe 11, and the absorbed water molecules slide down and fall into the drain nut 13. Opening the drain nut 13 facilitates the drainage of water and the replacement of the water-absorbing sponge 12, ensuring that the water molecules in the circulating gas are reduced and that the gas delivered to the lower chamber 1 remains dry, thereby achieving a drying effect.

[0039] Please see Figure 4 A filter screen 9 is installed inside the upper chamber 4 and on one side of the partition plate 8. The filter screen 9 is installed at the lower end of the air outlet box 10. The filter screen 9 and the air outlet box 10 are equipped with filter screens. The filter screen 9 is installed at the lower end of the air outlet box 10. The filter screen 9 and the air outlet box 10 filter impurities in the passing gas to ensure that the circulating drying gas contains impurities, which would affect the gas flow efficiency.

[0040] Please see Figure 4 The bracket 16 is installed in the middle of the lower housing 1. Control doors 2 are installed on both sides of the lower housing 1. The height of the bracket 16 is lower than the overall height of the control doors 2. By installing the bracket 16 in the middle of the lower housing 1 and opening the control doors 2, the bracket 16 can be moved into the lower housing 1 easily.

[0041] Please see Figure 5 and Figure 6The gear set 18 includes two sets of gears. One set of gears is fitted inside the first chain 17, and the other set of gears is fitted outside the second chain 19. A movable pin 22 is fixed on the side of the first chain 17. Slide grooves 23 are opened inside both sides of the drying plate 21. The gear set 18 is started by a door mounted on the outside. Through the transmission of the second chain 19, the two sets of first chains 17 are driven to rotate synchronously. The movable pin 22 installed inside the first chain 17 pushes one end of the drying plate 21 to move upward, and the movable pin 22 installed inside the first chain 17 pushes the drying plate 21 to move downward. That is, multiple sets of drying plates 21 are controlled to rotate synchronously to ensure the convenience of feeding modified polymer materials. The slide grooves 23 provide space for the movable pins 22 to move, ensuring the flexibility of the movable pins 22 when moving.

[0042] Please see Figure 7 The slider 26 has a first gear 27 and a second gear 28 installed inside. A stirring rod 29 is fixed to one end of the second gear 28. The first gear 27 and the second gear 28 mesh with each other. The lower end of the first gear 27 meshes with the toothed plate 24. The stirring rod 29 is in contact with the upper end of the drying plate 21. During the drying process of the modified polymer material placed on the upper end of the drying plate 21, the lead screw 25 is activated. The lead screw 25 and the slider 26 move in a threaded motion, that is, the slider 26 moves left and right on the upper end of the drying plate 21. At the same time, when the slider 26 moves, it drives the first gear 27 to mesh with the toothed plate 24. At the same time, the first gear 27 meshes with the second gear 28, that is, the second gear 28 drives the stirring rod 29 to rotate. When the stirring rod 29 rotates, it mixes and stirs the modified polymer material placed on the upper end of the drying plate 21.

[0045] Step 2: The control bracket 16 is movably sleeved inside the guide rail 15. The control door 2 is opened, and the control bracket 16 moves to the middle of the lower housing 1. At the same time, the hydraulic rod 3 is activated, and the hydraulic rod 3 drives the upper housing 4 to close at the upper end of the lower housing 1. At the same time, the control door 2 is closed to ensure that the lower housing 1 and the upper housing 4 are sealed. Meanwhile, the bracket 16 moves to the center of the lower housing 1.

[0046] Step 3: Start heater 6. Heater 6 heats the gas passing through it. The heated gas is evenly transmitted into the lower chamber 1 through heating box 5. The high temperature gas heats and dries the modified polymer material. At the same time, the dried gas flows back into the second transmission pipe 11 through filter screen 9 and gas outlet box 10. Start air pump 14. Air pump 14 provides power for the gas flow. The heated gas circulates in the lower chamber 1, thus realizing the drying operation of the modified polymer material.

[0047] Step 4: The temperature inside the lower chamber 1 is detected by the temperature control device to ensure that the lower chamber 1 is kept at a constant temperature. At the same time, the drying gas is delivered to the interior of the second transmission pipe 11, the water-absorbing sponge 12 absorbs the moisture, and the filtered gas flows back to the interior of the lower chamber 1 through the heating box 5.

[0048] Step 5: Start the lead screw 25. The lead screw 25 and the slider 26 move in a threaded motion, controlling the slider 26 to move laterally left and right. At the same time, the slider 26 drives the first gear 27 to mesh with the lead screw 25. The first gear 27 drives the second gear 28 to rotate. The second gear 28 drives the stirring rod 29 to rotate. The stirring rod 29 stirs the modified polymer material placed on the upper end of the drying plate 21 to ensure that the modified polymer material is fully mixed.

[0049] Step Six: Observe whether the modified polymer material is dried. After the modified polymer material is dried, push the support 16 to control the support 16 to be pushed out from the inside of the lower box 1. Start the motor installed on the outside of the gear set 18. The motor controls the first chain 17 to rotate. One set of the first chain 17 drives one side of the drying plate 21 to move upward through the movable pin 22, and the other set of the first chain 17 drives the drying plate 21 to move downward through the movable pin 22. That is, the drying plate 21 is kept in an inclined state to ensure that the modified polymer material is quickly unloaded.
