Description

Technical Field

[0001] The utility model relates to the technical field of wood drying equipment, in particular to an environment-friendly heat cycle furniture wood drying equipment. Background Technique

[0002] Furniture wood drying can prevent wood from deforming and cracking, improve the mechanical strength of wood and its physical properties, prevent wood from rotting and being damaged by pests, reduce the weight of wood and transportation costs, and enhance the grade of wood and furniture products. Among them, steam drying is widely used because of its high efficiency, high quality and good environmental protection. Steam drying uses a steam generator to heat water to produce dry saturated steam. This steam has a relatively high temperature and a relatively low humidity, which can effectively heat the wood and promote the evaporation of moisture in the wood. During the wood drying process, the role of the steam generator is not only to provide heat, but also to stably control the humidity to avoid over-drying of the wood, so as to achieve the best drying effect;

[0003] After drying is completed, the remaining steam in the drying box needs to be discharged to facilitate the workers to take out the wood. However, the existing equipment directly discharges the steam to the outside, which results in waste of steam and increased water resource consumption. Content of the Utility Model

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, An environment-friendly thermal cycle furniture wood drying device, including a drying box 1, a front closing door 4 is provided on the front of the drying box 1, a water tank 9 is provided on the outside of the drying box 1, a steam generator 10 is provided on the side of the water tank 9, a steam pipe 7 is provided on the steam generator 10, and the other end of the steam pipe 7 is distributed in the drying box 1. A high-temperature resistant fan 5 is provided on the top of the drying box 1, an exhaust pipe 6 is connected to the high-temperature resistant fan 5, the other end of the exhaust pipe 6 is connected to a condensation box 11, the bottom of the condensation box 11 is communicated with the water tank 9, and a heat dissipation fan is built in the condensation box 11;

[0026] In the present utility model, a high-temperature resistant fan 5 and a condensation box 11 are provided. When drying furniture wood, the steam generator 10 extracts the water in the water tank 9, and then heats the water to generate high-temperature and high-pressure dry saturated steam. The dry saturated steam enters the drying box 1 through the steam pipe 7 to dry the furniture wood. The temperature of the dry saturated steam is relatively high, which will cause the steam in the furniture wood to evaporate due to heat, achieving the purpose of reducing the dry water content in the furniture wood. When the drying work is completed, the steam generator 10 is turned off, and the high-temperature resistant fan 5 is turned on to draw the residual steam in the drying box 1 into the exhaust pipe 6. The steam enters the condensation box 11 through the exhaust pipe 6, and heat exchange is carried out with the outside through the condensation box 11 to reduce the steam temperature and condense it. The condensed water flows into the water tank 9 for recycling, achieving the purpose of recovering the steam, avoiding the waste of steam discharged to the outside, and reducing the consumption of water resources;

[0027] In addition, it should be further explained that when drying furniture wood, in order to improve the drying efficiency, the furniture wood can be stacked, but spacers need to be placed directly between the furniture wood so that the furniture wood can fully contact the dry saturated steam, achieving the effect of efficient and comprehensive drying of the furniture wood.

[0028] A circulation mechanism 8 is provided at a position near the bottom on the side of the drying box 1, and the other end of the circulation mechanism 8 is communicated with the water tank 9. The circulation mechanism 8 is used to collect the condensed water at the bottom of the drying box 1;

[0029] By setting the circulation mechanism 8, in the early stage of drying, the temperature in the drying box 1 is relatively low. At this time, the steam that first enters the drying box 1 will contact the low-temperature environment, and part of the steam will cool down and condense. The condensed water will accumulate at the bottom of the drying box 1, and the circulation mechanism 8 can collect the accidentally generated condensed water and transport it to the water tank 9 for recycling, further achieving the purpose of recycling water resources and improving the environmental protection efficiency of the equipment;

[0030] It should be further noted that there are many reasons for steam to cause condensation during drying. The above method is only one case. In addition, problems such as non-standard stacking of furniture wood resulting in low-temperature areas, reduced steam flow rate and insufficient heat transfer leading to a decrease in steam temperature, and changes in the pressure of steam in the drying box 1 will all cause the generation of condensate water.

[0031] The circulation mechanism 8 includes a drain pipe 803. The drain pipe 803 is arranged on the side of the drying box 1 and is internally provided with an electric valve. A water pump 801 is arranged at the end face of the drain pipe 803. A second motor 802 is arranged on the side of the water pump 801. The output end of the water pump 801 is provided with a circulation pipe 804. The other end of the circulation pipe 804 is communicated with the water tank 9.

[0032] By setting the drain pipe 803, the water pump 801 can pump out the condensate water in the drying box 1 through the drain pipe 803, so that the condensate water enters the water tank 9 through the circulation pipe 804 for storage, achieving the effect of recycling the condensate water, reducing the consumption of water resources, and at the same time avoiding the long-term accumulation of condensate water in the drying box 1. In addition, the drain pipe 803 is internally provided with an electric valve, which is opened when discharging condensate water and closed when there is no need to discharge condensate water, so as to avoid the overflow of steam through the drain pipe 803.

[0033] A filter 805 is arranged between the circulation pipe 804 and the water tank 9. The filter 805 is used to filter the condensate water in the circulation pipe 804.

[0034] By setting the filter 805, the filter 805 can filter the condensate water conveyed by the circulation pipe 804 and discharge it into the water tank 9 for storage after filtration, ensuring the cleanliness of the circulating water, preventing impurities or wood chips in the drying box 1 from entering the water tank 9, and preventing the normal operation of the steam generator 10 from being affected.

[0035] A rear closing door 12 is arranged on the back of the drying box 1. The rear closing door 12 is used for discharging wood.

[0036] By setting the rear closing door 12, the dried furniture wood can be moved out through the rear back of the drying box 1 through the rear closing door 12. With such a setting method, the drying box 1 can be arranged in the furniture wood production line facility, with the front closing door 4 for feeding and the rear closing door 12 for discharging, greatly improving the feeding and discharging efficiency of furniture wood drying work, and thus improving the overall efficiency of furniture wood drying.

[0037] Opening and closing mechanisms 2 are arranged on the sides of both the rear closing door 12 and the front closing door 4. A driving mechanism 3 is connected to the side of the opening and closing mechanism 2. Both the driving mechanism 3 and the opening and closing mechanism 2 are arranged on the side of the drying box 1.

[0038] By setting up the opening and closing mechanism 2 and the driving mechanism 3, the driving mechanism 3 can drive the opening and closing mechanism 2 to rotate. When the opening and closing mechanism 2 rotates, it will drive the front closing door 4 and the rear closing door 12 connected to it to rotate and open, achieving the purpose of automatically opening the front closing door 4 and the rear closing door 12, reducing the labor force of manual opening. At the same time, it can be paired with an automatic feeding and discharging device for furniture wood to achieve the purpose of completely automating the drying of furniture wood, greatly improving the production efficiency.

[0039] The opening and closing mechanism 2 includes a hinge seat 201. The hinge seat 201 is arranged on the side of the drying box 1. A rotating shaft 203 is rotatably arranged in the hinge seat 201. A connecting arm 202 is arranged on the side of the rotating shaft 203. The other end of the connecting arm 202 is connected to the front closing door 4 and the rear closing door 12.

[0040] By setting up the hinge seat 201 and the rotating shaft 203, the hinge seat 201 is rotatably connected to the rotating shaft 203, enabling the rotating shaft 203 to drive the connecting arm 202 to rotate horizontally. And the hinge seat 201 can bear the mass of the front closing door 4 and the rear closing door 12 through the rotating shaft 203 and the connecting arm 202, achieving the purpose of stable rotational opening and closing. In addition, the rotating shaft 203 can receive the power of the driving component to achieve the effect of automatic rotational opening and closing.

[0041] The driving mechanism 3 includes a first motor 301. A speed reducer 302 is arranged at the output end of the first motor 301. Driving shafts 303 are arranged at both ends of the speed reducer 302. The driving shafts 303 are connected to the side of the drying box 1 through bearing seats. A bevel gear set 304 is arranged between the end face of the driving shaft 303 and the rotating shaft 203.

[0042] By setting up the speed reducer 302 and the bevel gear set 304, the speed reducer 302 can transmit the power of the first motor 301 to the driving shaft 303 and reduce the rotational speed and increase the torque, enabling the driving shaft 303 to rotate stably. And the bevel gear set 304 can change the transmission direction to make the rotating shaft 203 and the driving shaft 303 transmit and cooperate, achieving the purpose of driving the opening and closing. And using the principle that the rotation directions of the bevel gear sets 304 at both ends are mirror images, the opening and closing mechanisms 2 on both sides can perform the opening and closing operations synchronously.

[0043] Working principle:

[0044] During drying, the steam generator 10 pumps out the water in the water tank 9, heats it to generate high-temperature and high-pressure dry saturated steam, and then uses the steam pipe 7 to transport the dry saturated steam into the drying box 1 to dry the furniture wood with the dry saturated steam. After drying, the high-temperature resistant fan 5 starts to discharge the remaining steam in the drying box 1 into the exhaust pipe 6. The steam enters the condensation box 11 through the exhaust pipe 6, condenses after heat exchange in the condensation box 11, and then the condensed condensate flows into the water tank 9 for circulation.

[0045] When condensate forms at the bottom of the drying oven 1, the second motor 802 drives the drainage pump 801 to work. The drainage pump 801 pumps out the condensate through the drainage pipe 803, and sends the condensate into the filter 805 through the circulation pipe 804. The filter 805 filters the condensate and then sends it into the water tank 9 for circulation.

[0046] After the remaining steam in the drying oven 1 is discharged, the first motor 301 drives the drive shaft 303 to rotate through the speed reducer 302. The drive shaft 303 drives the rotating shaft 203 to rotate through the bevel gear set 304. The rotating shaft 203 drives the connecting arm 202 to rotate outward around the hinge seat 201 towards the outside of the box. When the connecting arm 202 rotates, it drives the front closing door 4 and the rear closing door 12 to rotate outward and open, pushing the new furniture wood into the drying oven 1 from the front end of the drying oven 1, and then moving the dried furniture wood out of the drying oven 1 through the rear end of the drying oven 1.

[0047] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
