[0002] In industrial production, workpieces often need to be heated and dried. Currently, the workpieces are usually placed in a heating furnace and quickly dried using hot air. However, the hot air direction of the current heating furnace is relatively single, and it is difficult to utilize the circulating flow of hot air to evenly heat the workpiece when heating the workpiece, which needs further improvement.

[0003] In formula number CN219810233U, the utility model discloses a heating furnace device with uniformly heated hot air circulation, which relates to the technical field of heating furnace devices. The heating furnace device is intended to solve the technical problem that the wind direction of the hot air in the heating furnace of the prior art is relatively single, and it is difficult to use the circulating flow of hot air to uniformly heat the workpiece when heating the workpiece. The heating furnace device includes a furnace body and a gas collector fixedly installed at the lower end of the furnace body; a symmetrical axial flow fan is fixedly installed at the upper end of the furnace body, a heating pipe is fixedly installed between the two axial flow fans, and connecting pipes are fixedly installed at both ends of the left and right ends of the furnace body, and one end of the connecting pipe passes through the axial flow fan The machine extends to the interior of the axial flow fan, and a gas collecting gas is fixedly installed at the lower end of the furnace body, and a fixed tube is fixedly installed at the lower end of the gas collecting gas. The heating furnace device can form circulating hot air by changing the wind direction to accelerate the drying effect of the workpiece. When heating the workpiece, the circulating flow of hot air can be used to evenly heat the workpiece. However, the above-mentioned transfer structure is relatively simple. During use, due to the high temperature, the circulating motor is easily damaged, and it is inconvenient to replace the circulating motor. When the circulating motor is removed, part of the internal liquid will be lost and needs to be reheated. Therefore, it is necessary to provide an internal circulation heating device with uniform heating to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 A uniformly heated internal circulation heating device comprises: a water tank 1, a heating device 2 provided on the lower surface of the water tank 1, two sets of water pipes 4 provided on both sides of the water tank 1, and the upper ends of the two sets of water pipes 4 are connected to connecting pipes 5, and an installation frame 6 is provided between the two sets of connecting pipes 5, a flow motor 7 is provided inside the installation frame 6, and the flow motor 7 is provided with a connection port 9 on both sides, and a one-way valve is provided inside the two sets of connecting pipes 5.

[0025] A heat conducting plate 3 is provided on the lower surface of the water tank 1. The heat conducting plate 3 is made of aluminum alloy. Aluminum alloy has good thermal conductivity and can transfer heat quickly and evenly, making it convenient for the heating plate to heat the water in the water tank 1.

[0026] Limit blocks are provided on the upper and lower sides of the interior of the mounting frame 6, and matching sliding grooves are provided on the upper and lower sides of the flow motor 7, and a handle 8 is provided on the front side of the flow motor 7. The coordinated use of the limit blocks and the sliding grooves can ensure the stability of the flow motor 7 during operation, reduce displacement caused by vibration or external force, and thus protect the motor and connected devices from damage. The design of the handle 8 provides convenience for the operator, so that the flow motor 7 can be easily taken out or put in when repair or maintenance is required, thereby improving the maintainability of the equipment.

[0027] The two groups of one-way valves include a mounting plate 10, an adjusting rod 11 is movably inserted in the middle position of the mounting plate 10, and a baffle 12 is provided at the right end of the adjusting rod 11, and a positioning block 13 is provided at the left end of the adjusting rod 11. A positioning spring 14 is sleeved on the outer end of the adjusting rod 11, and the left and right ends of the positioning spring 14 are respectively connected to the positioning block 13 and the mounting plate 10. A plurality of groups of holes are provided on the surface of the mounting plate 10, and the diameter of the baffle 12 is larger than the diameter of the position of the hole provided on the mounting plate 10. By adjusting the position of the positioning block 13, the adjusting rod 11 is moved, thereby releasing the blockage of the holes provided in the mounting plate 10 by the baffle 12, thereby facilitating liquid circulation. When the adjustment of the positioning block 13 is released, the positioning block 13 is driven to move by the elastic force of the positioning spring 14, so that the adjusting rod 11 drives the baffle 12 to block the holes provided on the surface of the mounting plate 10, thereby preventing water from flowing through.

[0028] The outer sides of the two groups of connecting ports 9 are both set to arc structures, and a support block 15 is set inside the connecting port 9. The arc structure can squeeze the position of the positioning block 13 when the connecting port 9 moves, thereby adjusting the position of the positioning block 13, and then the positioning block 13 is adjusted by the support block 15 inside the connecting port 9.

[0029] Filters 16 are provided inside the two sets of connection ports 9 , and impurities in the liquid passing through the connection ports 9 can be filtered through the filter 16 .

[0030] Working principle: When in use, liquid is added to the water tank 1, and then the liquid in the water tank 1 is heated by the heating device 2, and the heating efficiency is improved by the heat conduction plate 3, and then the flow motor 7 is set in the installation frame 6 through the limit block in the installation frame 6 and the sliding groove opened by the flow motor 7. The oblique structure outside the connecting port 9 set on the left and right sides of the flow motor 7 makes the connecting port 9 squeeze the positioning block 13 when entering, thereby adjusting the position of the positioning block 13 and opening the one-way valve to facilitate the liquid to enter the flow motor 7, thereby accelerating the water circulation speed through the flow motor 7.
