Description

Technical Field

[0001] This invention relates to the technical field of high-efficiency drying equipment for sponge production, and particularly to a high-efficiency drying equipment and method for sponge production. Background Technology

[0002] Sponges are porous materials with good water absorption properties, which can be used to clean items. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. During the production process, sponges need to be forced to dry in order to carry out the curing process. However, the existing drying equipment used in sponge production has poor drying effect, resulting in excessive moisture content in the sponges and foam clumping, which is not conducive to sponge production.

[0003] Currently, Chinese invention patent CN219797683U discloses a sponge manufacturing drying device, including a base. A drying chamber is fixedly connected to the left side of the top of the base. A sealing door is rotatably connected to one side of the drying chamber via a hinge. The sealing door ensures that the heat inside the drying chamber will not escape. Heating tubes are installed at equal intervals on the inner wall of the drying chamber. A fixing rod is fixedly connected to the top of the heating tubes. An electric telescopic rod is fixedly connected to the top of the drying chamber. A partition is fixedly connected to the output end of the electric telescopic rod. Control rods are fixedly connected at equal intervals to the bottom of the partition. A pressure plate is connected to the bottom of the partition via a support spring. An exhaust pipe is connected to the top of the pressure plate at equal intervals. The bottom end of the control rod is slidably connected to the inside of the exhaust pipe via a rubber piston.

[0004] Existing technologies utilize pressure plates during the sponge drying process to facilitate the expulsion of moisture from the sponge. Furthermore, the release of pressure allows heat to quickly penetrate the sponge, thus improving drying efficiency. However, on one hand, simply squeezing the sponge with pressure plates cannot completely remove all moisture, increasing the drying time and resulting in poor drying efficiency. On the other hand, this existing technology can only dry one sponge at a time, failing to meet the demand for simultaneous drying of large quantities of sponges during production, thus lacking sufficient drying efficiency and necessitating improvement. Summary of the Invention

[0009] The present invention is further configured such that the tooth ratio between the first rotating gear and the second rotating gear is not less than 3:1.

[0010] The present invention is further configured such that: the dehydration assembly includes a dehydration base coaxially fixedly connected to the bottom of the first drying cylinder and a dehydration shaft coaxially fixedly connected to the dehydration base; a dehydration bearing is fixedly connected to the base; the dehydration shaft is coaxially fixedly connected to the dehydration bearing; a first dehydration gear is coaxially fixedly connected to the dehydration shaft; a dehydration motor is fixedly connected to the base; and a second dehydration gear that cooperates with the first dehydration gear is fixedly connected to the output shaft of the dehydration motor.

[0011] The present invention is further configured such that the ratio of the number of teeth between the second dehydration gear and the first dehydration gear is not less than 2:1.

[0015] The second objective of this invention is to provide a sponge drying method, which has the advantages of simple structure, high drying efficiency, and the ability to simultaneously dry multiple sponges.

[0016] The above-mentioned technical objective of this invention is achieved through the following technical solution: a sponge drying method, comprising a high-efficiency drying device for sponge production according to any of the above-mentioned technical solutions; including:

[0017] Step 1: Stack several sponges vertically inside the water-pressing chamber;

[0018] Step 2: The concentric rotating assembly drives the second drying cylinder and the second water-pressing plate to rotate, thereby reducing the gap between the first water-pressing plate and the second water-pressing plate, and initially squeezing out the water from the sponge;

[0019] Step 3: While performing Step 2, the dehydration component drives the first drying cylinder and the second drying cylinder to rotate on the base, so that water is discharged from the sponge due to centrifugal force, thus achieving further drainage.

[0020] Step 4: After most of the water in the sponge is removed, the concentric rotating component drives the second drying cylinder and the second water pressing plate to rotate in the opposite direction, so that the distance between the first water pressing plate and the second water pressing plate returns to the initial state. The sponge rebounds, increasing the internal gap. The impact component drives the first drying cylinder and the second drying cylinder to impact downward. The water remaining in the sponge is subjected to a reaction force opposite to the impact force, so that the water remaining in the sponge is shaken apart and evenly dispersed into the sponge.

[0021] Step 5: The heating component generates heat, and the air intake component creates negative pressure at the water baffle ring, causing air to enter the water pressure chamber from the center of the first and second drying cylinders. During the air flow, the air carries away the heat generated by the heating component, thereby drying the sponge. Finally, the air is discharged from the air intake component.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. A first and second water-pressing plates are installed on the first and second drying cylinders, respectively, while a concentric rotating assembly is installed on the base to drive the second drying cylinder to rotate within the first drying cylinder. On one hand, the concentric rotating assembly drives the second drying cylinder to rotate, thereby reducing the distance between the first and second water-pressing plates and initially squeezing out the water from the sponge. On the other hand, it can simultaneously squeeze the sponges in multiple water-pressing chambers, meeting the need for drying a large number of sponges at the same time. During the squeezing process, the dewatering assembly drives the first and second drying cylinders to rotate on the base, causing water to be discharged from the sponge due to centrifugal force, thus achieving further drainage. This is achieved through the concentric rotating assembly and the dewatering assembly... The components work together to allow multiple sponges to undergo initial dehydration simultaneously. After the initial dehydration of the sponges is completed, the concentric rotating component drives the second drying cylinder and the second pressure plate to rotate in the opposite direction, thereby restoring the distance between the first and second pressure plates to their initial state. The sponge rebounds, increasing the internal gap. At this time, the lifting motor of the impact component drives the lifting roller to rotate, thereby lifting the impact sleeve to a certain height and then releasing it. The impact sleeve strikes the impact plate downwards. Since the position of the dehydration shaft on the base is fixed, the energy generated by the impact acts directly on the sponge, causing the residual water inside the sponge to be shaken apart and evenly distributed inside the sponge. This makes it easier for the heating component and the air-guiding component to dry the residual water inside the sponge, improving the drying effect.

[0024] 2. The heating component consists of a heating cylinder installed inside the second drying cylinder, with several heating wires inside. Simultaneously, the air intake component has air intake holes on the water-blocking ring, with an air intake motor and fan blades installed within these holes. The air intake component generates negative pressure at the water-blocking ring, causing air to enter the pressure chamber from the center of both the first and second drying cylinders. During airflow, the air carries away the heat generated by the heating component, thus drying the sponge. Finally, the air is discharged from the air intake component. Because the impact component disperses and evenly distributes the residual water inside the sponge, the hot air entering the sponge more easily evaporates the remaining moisture, thereby improving both drying efficiency and drying effect.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] refer to Figures 1 to 5A high-efficiency drying device for sponge production includes a fixed base 1. A water-retaining ring 11 is fixedly connected to the base 1 to prevent water splashing. A plurality of drainage holes 12 are evenly distributed at the bottom of the water-retaining ring 11, through which water detached from the sponge is discharged. A first drying cylinder 2, coaxially arranged with the water-retaining ring 11, is rotatably connected to the base 1. A second drying cylinder 3 is rotatably connected coaxially inside the first drying cylinder 2. A plurality of mutually cooperating first pressure plates 21 and second pressure plates 31 are fixedly arranged along the circumferential direction on the first drying cylinder 2 and the second drying cylinder 3, forming a pressure chamber 4 for placing the sponge. By placing the sponge in the pressure chamber 4 and compressing the pressure... The area of ​​the water chamber 4 is reduced to squeeze the water out of the sponge. A concentric rotating assembly 5 is fixed on the first drying cylinder 2 to drive the second drying cylinder 3 to rotate inside the first drying cylinder 2. The area of ​​the water-pressing chamber 4 is reduced by the concentric rotating assembly 5. A dehydration assembly 6 and an impact assembly 7 are fixed on the base 1 to drive the first drying cylinder 2 and the second drying cylinder 3 to rotate and impact on the base 1 to achieve sponge dehydration. The dehydration assembly 6 is used to cooperate with the concentric rotating assembly 5 to achieve the effect of squeezing the sponge and discharging water from the sponge through centrifugal force, thereby achieving further drainage. A heating assembly 8 and an air-guiding assembly 9 for drying the sponge are fixed on the first drying cylinder 2 and the water-blocking ring 11, respectively.

[0034] refer to Figures 4 to 5Specifically, the first drying cylinder 2 includes a first drying seat 22 rotatably connected to the base 1 and a first fixed cylinder 23 coaxially fixed to the first drying seat 22. A plurality of first drain outlets 27 are evenly distributed on the first drying seat 22 to discharge the squeezed-out water. Simultaneously, a plurality of first vent holes 24 are evenly distributed on the first fixed cylinder 23. These vent holes 24 allow for ventilation and also allow the separated water to drain during the dehydration process of the dehydration component 6. A plurality of first positioning and fixing grooves 25 for inserting the first pressure plate 21 are evenly distributed along the circumference on the first drying seat 22 and the first fixed cylinder 23. At the same time, first reinforcing seats 26 are fixed at both ends of the first positioning and fixing grooves 25 on the first fixed cylinder 23 to abut against the first pressure plate 21. The first reinforcing seats 26 ensure the stability of the first pressure plate 21 fixed on the first fixed cylinder 23, and can also be adjusted according to the size of the sponge. The position and number of the first water-pressing plates 21 are adjusted to adapt to the drying needs of sponges of different sizes. The second drying cylinder 3 includes a second drying seat 32 coaxially rotatably connected to the first fixed cylinder 23 and a second fixed cylinder 33 coaxially fixed to the second drying seat 32. A number of second drain outlets 35 are evenly opened on the second drying seat 32, and a number of second vent holes 34 are evenly opened on the second fixed cylinder 33. A number of second positioning and fixing grooves 36 for inserting the second water-pressing plates 31 are evenly opened along the circumferential direction on the second fixed cylinder 33. Second reinforcing seats 37 are symmetrically fixed at both ends of the second water-pressing plates 31 along the vertical direction on the second fixed cylinder 33. In order to further improve stability, the parts of the first water-pressing plates 21 and the second water-pressing plates 31 inserted into the first positioning and fixing grooves 25 and the second positioning and fixing grooves 36 are arc-shaped and thicker than other parts, thereby ensuring the stability of the inserted parts.

[0035] refer to Figure 1Specifically, the concentric rotating assembly 5 includes a rotating seat 51 coaxially fixedly connected to the first drying seat 22 and a first rotating gear 52 coaxially fixedly connected to the end of the second fixed cylinder 33 away from the second drying seat 32. The rotating seat 51 is fixedly connected to the first drying seat 22 based on the support column, so that it rotates together with the first drying cylinder 2 during the dehydration process. A reduction motor 53 is fixedly connected to the rotating seat 51. The reduction motor 53 is a combination of a motor and a reducer, so that it can apply greater torque. A second rotating gear 54 that cooperates with the first rotating gear 52 is fixedly connected to the rotating shaft of the reduction motor 53. The reduction motor 53 drives the second rotating gear 54 to rotate, thereby driving the first rotating gear 52 to rotate. Several balance blocks 55 are also fixedly provided on the rotating seat 51 to maintain balance during the rotation process. After adjusting the position and number of the first water pressing plate 21 according to the size of the sponge to adapt to the drying needs of sponges of different sizes, the position and number of balance blocks 55 need to be adjusted to ensure the stability of the dehydration process. In this embodiment, the tooth ratio between the first rotating gear 52 and the second rotating gear 54 is not less than 3:1, which greatly increases the squeezing force acting on the sponge and improves the drying effect; preferably, it is 4:1.

[0036] refer to Figure 1 and Figure 3 Specifically, the dehydration assembly 6 includes a dehydration seat 61 coaxially fixed to the bottom of the first drying cylinder 2 and a dehydration shaft 62 coaxially fixed to the dehydration seat 61. A dehydration bearing 63 is fixedly connected to the base 1 to ensure dehydration stability while preventing the dehydration shaft 62 from moving up and down on the base 1, thus affecting stability. The dehydration shaft 62 is coaxially fixed inside the dehydration bearing 63 and welded inside the dehydration bearing 63. A first dehydration gear 64 is coaxially fixedly connected to the dehydration shaft 62. A dehydration motor 65 is fixedly connected to the base 1. A second dehydration gear 66 that cooperates with the first dehydration gear 64 is fixedly connected to the output shaft of the dehydration motor 65. The dehydration motor 65 drives the second dehydration gear 66 to rotate, which in turn drives the first dehydration gear 64 to rotate, thereby driving the dehydration shaft 62 to rotate, thus realizing the dehydration of the sponge. In this embodiment, the tooth ratio between the second dehydration gear 66 and the first dehydration gear 64 is not less than 2:1, and preferably 2:1.

[0037] refer to Figure 1 and Figure 2Specifically, the impact assembly 7 includes an impact plate 71 fixedly connected to the dehydration shaft 62 away from the dehydration seat 61, and an impact sleeve 72 coaxially sleeved and connected to the dehydration shaft 62. Several counterweights 73 are evenly fixedly arranged on the impact sleeve 72. A lifting rope 74 is fixedly connected to the impact sleeve 72 for lifting the impact sleeve 72 upwards on the dehydration shaft 62. A lifting motor 76 is fixedly arranged on the base 1 for pulling and releasing the lifting rope 74. A lifting roller 77 is coaxially fixedly connected to the rotating shaft of the lifting motor 76. After the sponge has undergone initial dehydration, the concentric rotating assembly 5 drives the second drying cylinder 3 and the second pressure plate. The reverse rotation of plate 31 restores the distance between the first pressure plate 21 and the second pressure plate 31 to its initial state. The sponge rebounds, increasing the internal gap. At this time, the lifting motor 76 of the impact assembly 7 drives the lifting roller 77 to rotate, thereby lifting the impact sleeve 72 to a certain height and then releasing it. The impact sleeve 72 strikes the impact plate 71 downward. Since the position of the dehydration shaft 62 on the base 1 is fixed, the energy generated by the impact acts directly on the sponge, causing the residual water inside the sponge to be shaken and evenly distributed inside the sponge. This makes it easier for the heating assembly 8 and the air-driing assembly 9 to dry the residual water inside the sponge, improving the drying effect.

[0038] refer to Figure 1 Specifically, the heating assembly 8 includes a heating cylinder 81 coaxially fixedly connected inside the second drying cylinder 3 and an air inlet 82 coaxially opened inside the heating cylinder 81. The end of the air inlet 82 away from the base 1 is tapered and flared to increase the air intake. A plurality of heating vent holes 83 are evenly opened on the heating cylinder 81, and a plurality of heating wires 84 are evenly fixed inside the heating cylinder 81. The air intake assembly 9 includes a plurality of air intake holes 92 evenly opened along the circumferential direction on the water baffle ring 11. An air intake motor 93 is fixedly installed in each air intake hole 92, and a fan is fixedly connected to the air intake motor. The exhaust fan 94 on the motor 93 and the exhaust assembly 9 generate negative pressure at the water baffle ring 11, causing air to enter the water pressure chamber 4 from the center of the first drying cylinder 2 and the second drying cylinder 3. During the air flow, the air carries away the heat generated by the heating assembly 8, thereby drying the sponge. Finally, the air is discharged from the exhaust assembly 9. Because the residual water in the sponge is shaken and evenly distributed in the sponge by the impact assembly 7, the hot air can more easily evaporate the residual moisture in the sponge after entering the sponge, thereby improving the drying efficiency and the drying effect.

[0039] Example 2:

[0040] A method for drying sponges, using a high-efficiency drying apparatus for sponge production as shown in Example 1, includes:

[0041] Step 1: Stack several sponges vertically inside the water-pressing chamber 4;

[0042] Step 2: The concentric rotating assembly 5 drives the second drying cylinder 3 and the second water pressing plate 31 to rotate, thereby reducing the gap between the first water pressing plate 21 and the second water pressing plate 31, and initially squeezing out the water from the sponge.

[0043] Step 3: While performing step 2, the dehydration component 6 drives the first drying cylinder 2 and the second drying cylinder 3 to rotate on the base 1, thereby causing water to be discharged from the sponge due to centrifugal force, thus achieving further drainage.

[0044] Step 4: After most of the water in the sponge is removed, the concentric rotating component 5 drives the second drying cylinder 3 and the second water pressing plate 31 to rotate in the opposite direction, so that the distance between the first water pressing plate 21 and the second water pressing plate 31 returns to the initial state. The sponge rebounds, increasing the internal gap. The impact component 7 drives the first drying cylinder 2 and the second drying cylinder 3 to impact downward. The water remaining in the sponge is subjected to a reaction force opposite to the impact force, so that the water remaining in the sponge is shaken apart and evenly dispersed into the sponge.

[0045] Step 5: The heating component 8 generates heat, and the air intake component 9 generates negative pressure at the water baffle ring 11, causing air to enter the water pressure chamber 4 from the center of the first drying cylinder 2 and the second drying cylinder 3. During the air flow, the air carries away the heat generated by the heating component 8, thereby drying the sponge. Finally, the air is discharged from the air intake component 9.
