Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, and in particular relates to a steam drying device. Background Technology

[0002] Steam drying technology is a method of drying materials using superheated high-temperature steam as a heat source. It is widely used in many fields, such as metallurgy, food processing, textiles, chemicals, paper manufacturing, and wood processing. It achieves efficient drying of materials while reducing water waste. It is suitable for small and medium-sized production workshops, laboratories, agricultural product processing cooperatives, and other scenarios, and is especially suitable for materials that are sensitive to drying temperature and require gentle drying.

[0003] For example, Chinese patent CN222912266U discloses a steam drying device, including an air inlet; the air inlet is connected in sequence to a main pipeline, an input pipeline, a heating assembly, an exhaust pipeline, and an air outlet via pipes; the main pipeline includes a shut-off valve, a filter, and a first solenoid valve, all connected in sequence; the input pipeline includes a fourth control valve, a pressure regulating valve, a pressure gauge, and a second solenoid valve, all connected in sequence; the heating assembly includes a heater; the exhaust pipeline includes a second control valve; a backup pipeline is also connected between the main pipeline and the heating assembly via a pipe; the backup pipeline includes a first control valve. By setting up a backup pipeline, the machine can continue production during maintenance without stopping if some pipelines fail, even if some pipelines malfunction, thus improving production efficiency and enhancing safety and reliability.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in use, such as: its open structure allows for direct steam discharge, which not only wastes heat but also increases workshop humidity, affecting the production environment; poor sealing during the drying process leads to steam leakage, resulting in unstable drying temperatures and low material drying uniformity; furthermore, the device lacks an effective condensate recovery system, causing direct discharge of condensed steam and significant water waste. Therefore, we propose a steam drying device. Utility Model Content

[0006] The purpose of this invention is to provide a steam drying device to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a steam drying apparatus, comprising:

[0008] The base has a bottom heating box embedded in its inner wall. A top mounting plate is snapped onto the top of the bottom heating box. Fixing grooves are provided on both sides of the top of the top of the top mounting plate, and a steam permeable plate is installed between the two fixing grooves at the top of the top mounting plate.

[0009] A fixed frame, wherein extension plates are fixedly connected to both sides of the outer wall of the fixed frame, a transmission gear set is provided at the top of the extension plate, threaded rods are connected to both sides of the bottom end of the transmission gear set, a transmission block is drivenly connected to the bottom end of the two threaded rods, a fixed top cover is fixedly connected to the bottom end of the two transmission blocks, and a top cover is installed at the bottom end of the fixed top cover.

[0010] A steam condenser is provided, with a top condensate tank fixedly connected to its top. Multiple cooling fans are installed on both sides of the outer wall of the steam condenser. A transfer pump is installed on one side of the top condensate tank. The output end of the transfer pump is connected to a condensate transfer pipe. Two cooling coils are installed on the end of the condensate transfer pipe away from the transfer pump. A condenser rack is installed on the inner wall of the steam condenser on one side of the two cooling coils.

[0011] In this technical solution, the bottom heating box embedded in the inner wall of the base is a hollow cavity structure used to store water to be heated. The top of the bottom heating box is fixed with a top snap-fit ​​plate by snap-fit. The top snap-fit ​​plate serves as a sealing cover for the bottom heating box to prevent water from overflowing, and also provides a support surface for placing materials. The steam permeable plate at the top allows the steam generated by heating to diffuse evenly upwards, ensuring that the materials are heated evenly.

[0012] The fixed frame is fixed to both sides of the top of the base, and extension plates are fixedly connected to both sides of the outer wall. A transmission gear set is set at the top of the extension plate. The transmission gear set is connected to an external motor to provide power for transmission. Threaded rods are connected to both sides of the bottom of the transmission gear set. The threaded rods extend vertically downwards and are connected to the transmission block through threaded transmission. After the motor starts, it drives the transmission gear set to rotate, which in turn drives the threaded rods to rotate, causing the transmission block to move up and down along the threaded rods, which in turn causes the fixed top cover and the top cover to slide up and down.

[0013] The steam condenser is a hollow chamber used to house the condensation components. A top condensate tank is fixedly connected to its top, which stores cooling water. A transfer pump is installed on one side of the top condensate tank, which transfers the condensate to a condensate transfer pipe. Two cooling coils are installed at the end of the condensate transfer pipe away from the transfer pump, and the cooling coils are located inside the steam condenser to increase the contact area with the steam. After the transfer pump is started, it delivers the cooling water from the top condensate tank to the cooling coils. The cooling water circulates within the cooling coils, absorbing heat from the steam. The wet steam is then condensed into condensate through a metal mesh condenser frame.

[0014] In the above technical solution, two wiring terminals are further installed on one side of the outer wall of the bottom heating box, one end of the two wiring terminals is connected to an internal heating rod, and the two internal heating rods are located inside the bottom heating box.

[0015] In this technical solution, two wiring terminals are installed on one side of the outer wall of the bottom heating box. The wiring terminals can be connected to an external power source to provide power to the internal heating rods. The two internal heating rods are located inside the bottom heating box and heat the water in the heating box to the boiling point to generate high-temperature steam.

[0016] In the above technical solution, furthermore, both sides of the bottom end of the top cover are provided with locking blocks, and both locking blocks correspond to the fixing groove.

[0017] In this technical solution, the top of the top plate is provided with fixing grooves on both sides. The fixing grooves are adapted to the locking blocks at the bottom of the top cover. When the top cover is lowered, the locking blocks are embedded in the fixing grooves to form a seal and prevent heat leakage from the top cover.

[0018] In the above technical solution, furthermore, both sides of the top of the fixed top cover are fixedly connected to transmission bellows, and the top ends of the two transmission bellows are fixedly connected to steam conduits.

[0019] In this technical solution, both sides of the top of the fixed top cover are fixedly connected to transmission corrugated pipes. The transmission corrugated pipes are telescopic and can extend and retract synchronously with the lifting and lowering of the fixed top cover to avoid damage to the pipes. The top of the transmission corrugated pipes is fixedly connected to a steam conduit. The end of the steam conduit away from the transmission corrugated pipe is fixed to the top side of the steam condensation box and passes through the top of the fixed frame. During the drying process, the wet steam generated by the evaporation of the material is transported to the steam condensation box through the transmission corrugated pipes and the steam conduit for condensation treatment.

[0020] In the above technical solution, further, the end of the steam conduit away from the transmission bellows is fixed to the top side of the steam condenser, and the outer wall of the steam conduit penetrates the top of the fixing frame.

[0021] In this technical solution, the outer wall of the steam conduit extends through the top of the fixed frame, allowing the wet steam generated by the evaporation of the material to be transferred to the steam condenser.

[0022] In the above technical solution, a condensate pipe is further fixedly connected to one side of the outer wall of the steam condenser, and the end of the condensate pipe away from the steam condenser is fixed to the input end of the transfer pump two.

[0023] In this technical solution, by setting up a condensate water conduit, the condensed steam water can be transported to the second transfer pump for delivery.

[0024] In the above technical solution, the output end of the second transfer pump is connected to the bottom heating box through a pipe, and the second transfer pump is located on one side of the steam condensing box.

[0025] In this technical solution, the condensed water flows into the second transfer pump through the condensate pipe, and is then transported back to the bottom heating box by the second transfer pump, where it is reheated to generate steam, thus realizing the recycling of water resources and reducing waste. At the same time, the high temperature of the condensate can reduce the energy consumption of the heating box.

[0026] The beneficial effects of this utility model are:

[0027] 1. This steam drying device distributes steam evenly through a steam permeation plate and maintains temperature by keeping the chamber under pressure, which increases the contact area between steam and material, improves heat utilization, shortens the drying cycle, and reduces the error in material drying uniformity compared to traditional hot air drying.

[0028] 2. This steam drying device, through the synergistic action of cooling coils and condenser racks, enables the steam to be condensed and recovered. The condensate is then recycled back to the heating box via a transfer pump for secondary use, preventing serious waste of water resources. At the same time, the waste heat carried by the condensate can reduce heating energy consumption and reduce carbon emissions compared to traditional steam drying equipment.

[0052] Example 6: This example provides a steam drying device, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0053] A condensate pipe 38 is fixedly connected to one side of the outer wall of the steam condenser 3.

[0054] Example 7: This example provides a steam drying device, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0055] The output end of the transfer pump 39 is connected to the bottom heating box 11 through a pipe, and the transfer pump 39 is located on one side of the steam condenser box 3.

[0057] Working principle: The material to be dried is evenly spread on the steam permeation plate 16 of the top clamping plate 14. An appropriate amount of water is added through the bottom heating box 11. The drive motor of the fixed frame 2 is started, and the drive gear set 22 drives the threaded rod 23 to rotate. The drive block 24 drives the fixed top cover 18 to slowly descend. When the clamping block 19 of the top cover 17 is inserted into the fixing groove 15 of the top clamping plate 14, the motor stops, and the top cover 17 is sealed. The power supply of the connector 12 is connected, and the internal heating rod 13 begins to heat. The water in the bottom heating box 11 gradually heats up, generating high-temperature steam. The steam diffuses evenly into the top cover 17 through the porous structure of the steam permeation plate 16, making full contact with the material. The moisture in the material absorbs the heat of the steam and evaporates, forming wet steam. During the drying process, the wet steam in the top cover 17 enters the steam conduit 31 through the transmission corrugated pipe 110 at the top of the fixed top cover 18, and then... Steam is transported to the steam condenser 31 via the steam duct 31 for condensation. The transmission corrugated pipe 110 can extend and retract with the top cover 17 to prevent pipe damage. The first transmission pump 33 is started, and the cooling water in the top condensate tank 32 flows into the cooling coil 35 through the condensate transmission pipe 34 and circulates within the cooling coil 35. After entering the steam condenser 3, the wet steam flows through the cooling coil 35 and the condenser rack 37, where the heat is absorbed by the cooling water, and the steam condenses into liquid water. The cooled water that has absorbed the heat flows back to the top condensate tank 32, is cooled by the cooling fan 36, and then participates in the condensation cycle again. The water produced by condensation collects at the bottom of the steam condenser 3 under gravity and flows into the second transmission pump 39 through the condensate duct 38. The second transmission pump 39 is started, and the condensate is transported back to the bottom heating box 11, where it is reheated by the internal heating rod 13 to generate steam, thus realizing the recycling of water resources and heat.
