Mesh crates can only hold solid items, while enclosed crates can hold both solid and liquid items. Disposable plastic crates; drying equipment such as ovens are major energy-consuming equipment in industrial production.

[0003] When traditional ovens remove burrs and flash from plastic baskets, over 80% of the electrical energy consumed is discharged into the air with the exhaust system due to the need for continuous forced ventilation during production, resulting in significant waste. Therefore, we need to propose a waste heat recovery oven. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a waste heat recovery oven, including an oven body 1, a heating cover 2 installed on the lower surface of the oven body 1, a first circulation cover 3 provided on one side of the heating cover 2, a first circulation fan 4 installed in the inner cavity of the first circulation cover 3, a waste heat recovery cover 7 installed on the upper surface of the heating cover 2, a second circulation cover 8 installed on one side of the waste heat recovery cover 7, a second circulation fan 9 installed in the inner cavity of the second circulation cover 8, waste heat recovery inlet holes 11 connected to the waste heat recovery cover 7 and the heating cover 2 respectively opened on both sides of the oven body 1, waste heat recovery outlet holes 12 connected to the first circulation cover 3 and the second circulation cover 8 respectively opened on both sides of the oven body 1, multiple sets of heating wires 5 are provided in the inner cavity of the heating cover 2, a wind baffle mechanism 6 is installed in the inner cavity of the oven body 1, and a material frame mounting hole 13 is opened on the side of the oven body 1 adjacent to the first circulation cover 3, and a material frame body 10 is inserted into the material frame mounting hole 13.

[0020] The wind baffle mechanism 6 includes an air outlet sealing assembly, a transmission assembly, an air inlet sealing assembly, and a reset assembly. The air outlet sealing assembly is located between two sets of waste heat recovery outlet holes 12, and the air inlet sealing assembly is located between two sets of waste heat recovery inlet holes 11. The transmission assembly and the reset assembly are both located between the air outlet sealing assembly and the air inlet sealing assembly. The wind baffle assembly facilitates the opening of the air vent when the material frame body 10 enters the oven body 1, thereby facilitating the hot air to be blown out while simultaneously recovering and reusing the hot air, thus improving the utilization rate of the hot air.

[0021] The air outlet sealing assembly includes a first wind baffle 61, two sets of first side plates 63, and multiple sets of guide strips 62. The first wind baffle 61 is mainly formed by two sets of flat beams and two sets of vertical beams. The two sets of flat beams are slidably connected to the two sets of guide strips 62 respectively. The two sets of first side plates 63 are fixedly connected to the opposite side of the two sets of vertical beams. The first wind baffle 61 facilitates the sealing of the waste heat recovery inlet 11 to prevent heat from flowing out and reduce energy consumption. The vertical beams facilitate the opening of the air vents of the first wind baffle 61 and the second wind baffle 612 when the material frame body 10 enters.

[0022] The air inlet sealing assembly includes a second baffle frame 612 and two sets of second side plates 611. The two sets of second side plates 611 are respectively fixedly connected to both sides of the second baffle frame 612. The second baffle frame 612 facilitates the sealing of the waste heat recovery inlet 11, thereby preventing heat from flowing out after the material frame body 10 is removed from the oven body 1.

[0023] The transmission assembly includes two sets of first piston cylinders 65 and two sets of second piston cylinders 68. A first push rod 64 is inserted into one end of the first piston cylinder 65. A first piston plate 66 is fixedly connected to one end of the first push rod 64 located in the inner cavity of the first piston cylinder 65. The end of the first push rod 64 opposite to the first piston plate 66 is fixedly connected to one side of the first side plate 63. The medium in the first piston cylinder 65 is squeezed by the first piston plate 66 on the first push rod 64, so that the medium is introduced into the second piston cylinder 68 through the connecting pipe 67. The structure is simple.

[0024] A second push rod 610 is inserted into one end of the second piston cylinder 68. A second piston plate 69 is fixedly connected to one end of the second push rod 610 located in the inner cavity of the second piston cylinder 68. The end of the second push rod 610 away from the second piston plate 69 is fixedly connected to one side of the second side plate 611. A connecting pipe 67 connects the first piston cylinder 65 and the second piston cylinder 68. The connecting pipe 67 facilitates the introduction of medium into the second piston cylinder 68 to adjust the position of the second piston plate 69, thereby synchronizing the position of the second push rod 610 to drive the position of the second windshield frame 612, thus achieving linkage.

[0025] The reset assembly includes two sets of first fixing blocks 613 fixedly connected to the first baffle frame 61 and two sets of second fixing blocks 614 fixedly connected to the second baffle frame 612. A telescopic sleeve 615 is fixedly connected between the two sets of first fixing blocks 613 and the two sets of second fixing blocks 614. A spring 616 is sleeved on the outside of the telescopic sleeve 615. The telescopic sleeve 615 and the spring 616 facilitate the material frame body 10 to be separated from the oven body 1, so that the first baffle frame 61 and the second baffle frame 612 can close the waste heat recovery inlet 11 and the waste heat recovery outlet 12 to prevent heat loss.

[0026] In use, the heating wire 5 is controlled by an external temperature controller to raise the temperature inside the heating cover 2. The material frame body 10 is embedded into the material frame mounting hole 13. The material frame body 10 is installed in the oven body 1 in a sealed manner to prevent hot air from escaping. After the material frame body 10 is inserted into the oven body 1, it abuts against the vertical beam of the first baffle frame 61, thereby driving the first piston plate 66 at the end of the first push rod 64 on the first side plate 63 to compress the medium (which can be water) in the first piston cylinder 65. This causes the water to enter the second piston cylinder 68 through the connecting pipe 67 and compress the second piston plate 69. The second piston plate 69 is then pushed by the second push rod 64. 10 abuts against the second side plate 611, causing the second baffle frame 612 to approach the first baffle frame 61. The first baffle frame 61 and the second baffle frame 612 are respectively separated from the waste heat recovery inlet 11 and the waste heat recovery outlet 12. The first circulating fan 4 passes the heat in the heating cover 2 into the baking oven. The hot air enters the waste heat recovery cover 7 through the waste heat recovery inlet 11 and then re-enters the heating cover 2. Thus, under the action of the first circulating fan 4 and the second circulating fan 9, the hot air is blown onto the material frame body 10 through the waste heat recovery outlet 12, realizing the repeated recycling of waste heat and improving the efficiency of burr removal on the material frame body 10.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
