Description

Technical Field

[0001] The utility model relates to the technical field of wooden handicraft processing, in particular to a turnover drying device for wooden handicrafts. Background Technique

[0002] Wooden handicrafts have a wide variety, including furniture, lighting fixtures, ornaments, models, root carvings, the four treasures of the study, utensils, screens, doors, coat racks, tea tables, craft boxes, etc. These handicrafts have simple and natural designs, pure colors, and display the natural texture and warmth of wood. Wooden handicrafts are not only suitable for home use but also have artistic value and collection value.

[0003] The utility model patent with the authorized announcement number of CN213631356U discloses a turnover drying device for wooden handicrafts in the technical field of wooden handicrafts, including a drying box. A support frame is fixedly connected to the bottom of the drying box. Rotating rollers are symmetrically and rotatably connected to the left and right sides of the inner cavity of the drying box. A conveyor belt is sleeved between the two groups of rotating rollers. Inverting components are fixedly connected to the conveyor belt evenly. Two rows of stop rods arranged in an array are fixedly connected to the rear side wall of the inner cavity of the drying box evenly. The two rows of stop rods are respectively located above and below the conveyor belt. An air exchange pipe is fixedly connected and communicated with the center of the top of the drying box. A valve is installed at the top of the air exchange pipe.

[0004] When the above patent heats and dries wooden handicrafts, in order to prevent moisture from returning during the drying process, an exhaust fan needs to be turned on to discharge the moisture inside the drying box. However, a large amount of heat loss will occur during the discharge process, resulting in low thermal cycle efficiency. Therefore, the energy-saving performance during drying is poor. To solve the above deficiencies, we propose a turnover drying device for wooden handicrafts. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and propose a turnover drying device for wooden handicrafts.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A turnover drying device for wooden handicrafts includes a wooden handicraft oven. An air inlet pipe, an air outlet pipe, a middle bearing pipe, and a connecting air pipe are sequentially connected to the outside of the wooden handicraft oven. A dehumidification mechanism is arranged on the lower side of the middle bearing pipe; the dehumidification mechanism includes a lower bearing pipe and a cooling water tank. The lower bearing pipe is internally connected and communicated with the middle bearing pipe. A water pipe is communicated and installed on the side of the lower bearing pipe. A vertical branch pipe is installed on the upper side of the water pipe. A ring pipe is communicated and installed on the upper side of the vertical branch pipe. A plurality of vertical pipes are installed inside the ring pipe. A self-priming water pump is arranged inside the cooling water tank. The output end of the self-priming water pump is connected and communicated with the outside of the water pipe.

[0008] Preferably, a box door is rotatably installed on the front side of the wooden handicraft oven, and a controller is fixedly installed on the box door.

[0009] Preferably, a humidity sensor and a temperature sensor are fixedly installed on the inner wall of the wooden handicraft oven, and both the humidity sensor and the temperature sensor are electrically connected to the controller.

[0010] Preferably, the air outlet pipe, the middle bearing pipe, the connecting air pipe and the air inlet pipe are all installed by screwing through connecting flanges.

[0011] Preferably, an electric heating wire is installed at the intersection of the air inlet pipe and the wooden handicraft oven.

[0012] Preferably, a circulating blowing mechanism is arranged at the upper end of the air inlet pipe. The circulating blowing mechanism includes an installation groove, an installation ring is installed inside the installation groove, an electric motor is arranged inside the installation ring, a plurality of connecting rods are connected between the electric motor and the installation ring, and a blade is installed at the output end of the electric motor.

[0013] Preferably, a drain pipe is connected and installed at the rear side of the cooling water tank, and a valve is arranged on the drain pipe.

[0014] Preferably, a solenoid valve is arranged at the bottom opening of the lower bearing pipe.

[0015] Compared with the related technology, a wooden handicraft flipping and drying device proposed by the present invention has the following beneficial effects:

[0016] In the present invention, in the wooden handicraft flipping and drying device, through the provided dehumidification mechanism, the whole dehumidification mechanism is arranged below the middle bearing pipe. When the circulating hot air passes through the middle bearing pipe, it will pass through the vertical pipe in the dehumidification mechanism. The vertical pipe is provided with cooling water by a self-priming water pump from the cooling water tank. Therefore, the temperature of the outer wall of the vertical pipe is relatively low. When the water vapor in the circulating hot air contacts the wall of the vertical pipe, the water vapor is cooled and liquefied. The liquefied water droplets converge into a water flow and flow down along the vertical pipe into the lower bearing pipe. Finally, the collected water flow accumulates inside the lower bearing pipe. The dehumidification mechanism is used to liquefy the water vapor generated during the drying process of the device from the air, reduce the humidity in the circulating hot air, and avoid the wooden handicrafts from getting damp due to excessive moisture in the circulating hot air. In addition, through the setting of the dehumidification mechanism, the whole drying process has no hot air leakage, reduces heat loss, and makes the device more energy-saving.

Detailed implementation manners

[0023] The present utility model will be further described below in conjunction with the drawings and implementation manners.

[0024] Refer to Figures 1-5 , and please refer to in conjunction with Figures 1-5 , where Figure 1 Schematic diagram of the three-dimensional structure of a wooden handicraft turning and drying device proposed by the present utility model Figure 1 ; Figure 2 Schematic diagram of the three-dimensional structure of a wooden handicraft turning and drying device proposed by the present utility model Figure 2 ; Figure 3 Partial three-dimensional structure schematic diagram of a wooden handicraft turning and drying device proposed by the present utility model Figure 1 ; 4 is the partial three-dimensional structure schematic diagram of a wooden handicraft turning and drying device proposed by the present utility model Figure 2 ; Figure 5 Partial three-dimensional sectional structure schematic diagram of a wooden handicraft turning and drying device proposed by the present utility model. A wooden handicraft turning and drying device includes: a wooden handicraft oven 1, an intake pipe 4, an exhaust pipe 5, a middle support pipe 7, and a connecting air pipe 6 are sequentially connected to the outside of the wooden handicraft oven 1, and a dehumidification mechanism 9 is arranged below the middle support pipe 7.

[0025] In this method, the dehumidification mechanism 9 includes a lower supporting pipe 91 and a cooling water tank 92. The lower supporting pipe 91 is internally connected to the middle supporting pipe 7. A water pipe 94 is connected and installed on the side of the lower supporting pipe 91. A vertical branch pipe 95 is installed on the upper side of the water pipe 94. A ring pipe 96 is connected and installed on the upper side of the vertical branch pipe 95. A number of vertical pipes 97 are installed inside the ring pipe 96. A self-priming pump 98 is arranged inside the cooling water tank 92. The output end of the self-priming pump 98 is connected to the outside of the water pipe 94.

[0026] Through the above arrangement, a number of vertical pipes 97 are installed inside the ring pipe 96. The arrangement of multiple vertical pipes 97 increases the contact area between the hot air and the vertical pipes 97 when the hot air passes through the vertical pipes 97, thereby accelerating the liquefaction of water vapor in the circulating hot air and accelerating the dehumidification effect.

[0027] In this method, a box door 2 is rotatably installed on the front side of the wooden handicraft oven 1. A controller 3 is fixedly installed on the box door 2. A humidity sensor 10 and a temperature sensor 11 are fixedly installed on the inner wall of the wooden handicraft oven 1. Both the humidity sensor 10 and the temperature sensor 11 are electrically connected to the controller 3.

[0028] Through the above arrangement, the controller 3 can monitor the humidity and temperature values inside the wooden handicraft oven 1 through the humidity sensor 10 and the temperature sensor 11.

[0029] In this method, the air outlet pipe 5, the middle supporting pipe 7, the connecting air pipe 6 and the air inlet pipe 4 are all installed by screwing with connecting flanges.

[0030] Through the above arrangement, the air outlet pipe 5, the middle supporting pipe 7, the connecting air pipe 6 and the air inlet pipe 4 are all installed by screwing with connecting flanges, which facilitates the disassembly and assembly between the pipes and the later maintenance and repair.

[0031] In this method, an electric heating wire 12 is installed at the intersection of the air inlet pipe 4 and the wooden handicraft oven 1.

[0032] Through the above arrangement, the electric heating wire 12 provides a heating effect when powered on. When air enters the air inlet pipe 4, the gas forms hot air under the heating effect of the electric heating wire 12, and the hot air is used to dry the wooden handicraft, which is convenient for taking away the moisture on the wooden handicraft.

[0033] In this method, a drain pipe 93 is connected and installed at the rear side of the cooling water tank 92. A valve is arranged on the drain pipe 93. A solenoid valve 99 is arranged at the bottom opening of the lower supporting pipe 91.

[0034] Through the above arrangement, the solenoid valve 99 arranged at the bottom opening of the lower supporting pipe 91 remains closed during the heating process to prevent the hot air in the middle supporting pipe 7 from leaking out.

[0035] In this method, a circulating blowing mechanism 8 is provided at the upper end of the air inlet pipe 4. The circulating blowing mechanism 8 includes an installation groove 81. An installation ring 82 is installed inside the installation groove 81. An electric motor 84 is arranged inside the installation ring 82. A number of connecting rods 83 are connected between the electric motor 84 and the installation ring 82. A blade 85 is installed on the output end of the electric motor 84.

[0036] Through the above arrangement, when the electric motor 84 is started, the blade 85 on its output end is driven to rotate, thereby generating a circulating blowing effect inside each pipeline.

[0037] The working principle of a wooden handicraft flipping and drying device provided by the present utility model is as follows:

[0038] During use, the wooden handicraft is placed into the wooden handicraft oven 1, the door 2 is closed, the electric motor 84 and the heating wire 12 are started synchronously. Under the action of the electric motor 84, the blade 85 is driven to rotate, and air is blown into the wooden handicraft oven 1 from the air inlet pipe 4. Through the action of the heating wire 12, hot air is generated. The hot air blows over the wooden handicraft, driving the moisture on the wooden handicraft. Subsequently, it flows back into the middle bearing pipe 7 from the air outlet pipe 5. When the water vapor in the hot air contacts the pipe wall of the vertical pipe 97, the water vapor is cooled and liquefied. The liquefied water droplets converge into a water flow and flow down along the vertical pipe 97 into the lower bearing pipe 91. Finally, the collected water flow accumulates inside the lower bearing pipe 91, reducing the humidity in the circulating hot air and preventing the wooden handicraft from getting damp due to excessive moisture in the circulating hot air. The dehumidified circulating hot air returns to the air inlet pipe 4 through the connecting air pipe 6 to form a hot circulating air. While the dehumidifying mechanism 9 is working, the self-priming pump 98 in it regularly circulates and changes the water in the vertical pipe 97 to prevent the cooling water temperature in the vertical pipe 97 from being too high and affecting its liquefaction efficiency.

[0039] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
