The inner side wall of the plug-in cover is provided with a locking strip, and the inner side wall of the locking strip is provided with a push spring. The push spring is located on the inner side wall of the plug-in cover.

[0012] As a further technical solution, a fan sleeve is provided on the heat recovery cover, the fan sleeve is embedded inside the heat recovery cover, and a heat recovery fan is provided inside the fan sleeve.

[0013] As a further technical solution, the push-in baking assembly includes a push-in guide rail, which is opened on the inner bottom surface of the baking box. A baking rack is installed inside the baking box, and a moving wheel is provided at the lower end of the baking rack. The moving wheel is inserted into the push-in guide rail.

[0014] As a further technical solution, the side wall of the baking rack has an insertion slot, and a display rack is inserted into the insertion slot.

[0015] As a further technical solution, the inner wall of the baking oven is provided with a positioning frame, which is embedded inside the heating coil.

[0016] As a further technical solution, the baking box has an insertion port, the baking rack is inserted into the insertion port, the insertion port is provided with a placement strip, and a sealing buckle is connected to the placement strip by a pin.

[0017] As a further technical solution, the baking oven is connected to mains power, and the upper surface of the baking oven is provided with a control slope, and the control slope is provided with an adjustment knob.

[0018] As a further technical solution, a connecting pipe is provided on the upper end face of the plug cover, and the connecting pipe and the connecting pipe are sealed and plugged together.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, the equipment achieves heat recovery through a regenerative plug-in assembly. During the biscuit baking process, the hot air generated inside the baking oven is collected by the regenerative hood, driven by the regenerative fan, and transported to the external heat recovery device through the connecting pipe. The heat of the hot air is transferred and utilized, avoiding the energy waste of direct heat emission in traditional equipment. According to tests, compared with traditional equipment, this equipment can recover about 30%-40% of the heat during the baking process, reducing the production cost of enterprises while reducing thermal pollution to the environment, which is in line with the current green and environmentally friendly production concept.

[0036] The regenerative plug-in assembly 3 is disposed on the upper end face of the baking oven 1;

[0037] Push in baking component 4 and insert it into baking box 1;

[0038] The regenerating plug-in assembly 3 includes a regenerating cover 3-1, which is plugged into the upper end face of the baking oven 1. A plug-in pipe 3-2 is provided at the upper end of the regenerating cover 3-1. A connecting pipe 3-3 is plugged into the plug-in pipe 3-2. A plug-in cover 3-4 is provided at the end of the connecting pipe 3-3. A locking strip 3-5 is provided on the inner side wall of the plug-in cover 3-4. A push spring 3-6 is provided on the inner side wall of the locking strip 3-5. The push spring 3-6 is provided on the inner side wall of the plug-in cover 3-4.

[0039] The push-in baking component 4 includes a push-in guide rail 4-1, which is located on the inner bottom surface of the baking box 1. A baking rack 4-2 is installed inside the baking box 1. A caster 4-3 is provided at the lower end of the baking rack 4-2, and the caster 4-3 is inserted into the push-in guide rail 4-1.

[0040] In some examples, the regenerating cover 3-1 is designed to fit snugly into the upper surface of the baking oven 1 using a sealed insertion method. For example, a sealing rubber ring is set at the edge where the regenerating cover 3-1 contacts the baking oven 1 to ensure the sealing of the connection and prevent heat loss. In actual installation, the operator aligns the regenerating cover 3-1 with the corresponding slot on the upper surface of the baking oven 1 and presses it vertically downward to make the regenerating cover 3-1 firmly inserted into place.

[0041] Connection of connector 3-2, connecting pipe 3-3, and connector cover 3-4: Connector 3-2 is fixed to the upper end of the heat recovery cover 3-1, using welding or threaded connection. One end of the connecting pipe 3-3 is tightly inserted into connector 3-2. To ensure a tight seal, sealing tape or sealant can be wrapped around the joint. The connection method between connector cover 3-4 and connecting pipe 3-3 is similar to that of connector 3-2, and a seal must also be ensured. Locking strip 3-5 is installed on the inner wall of connector cover 3-4, fixed by welding or adhesive. One end of push spring 3-6 is connected to the inner wall of locking strip 3-5, and the other end is fixed to the inner wall of connector cover 3-4. When external equipment (such as heat recovery pipes) is connected... When the plug cover 3-4 is inserted, the push spring 3-6 is compressed, and the locking strip 3-5 is tightly locked by the spring force to prevent the external equipment from falling off. After the external heat recovery pipe is inserted into the plug cover 3-4, the push spring 3-6 is compressed to two-thirds of its original length, and the locking strip 3-5 is tightly clamped to the outer wall of the pipe to ensure a firm connection. The guide rail 4-1 is opened on the inner bottom surface of the baking oven 1 and is formed by milling or casting. During installation, ensure that the flatness and straightness error of the guide rail are within the allowable range. Generally, the straightness error does not exceed ±0.5mm. The two ends of the guide rail are fixed to the inner bottom surface of the baking oven 1 by bolts or welding to ensure that the guide rail will not loosen during use.

[0042] Baking rack 4-2 is designed and manufactured according to the internal dimensions of baking box 1. A caster wheel 4-3 is installed at its lower end. The caster wheel 4-3 is connected to baking rack 4-2 via an axle. A bearing is used to connect the axle and baking rack 4-2 to reduce friction during movement. The diameter and material of the caster wheel 4-3 are selected based on the load-bearing capacity of baking rack 4-2 and the usage environment. If baking rack 4-2 has a large load-bearing capacity, a high-strength rubber wheel with a diameter of 80mm can be selected. When installing the caster wheel 4-3, first install the bearing in the axle mounting hole of baking rack 4-2, then pass the axle through the caster wheel 4-3 and the bearing. Use a nut or snap ring to secure the axle, ensuring that the caster wheel 4-3 is firmly installed and can rotate flexibly. When baking rack 4-2 is inserted into insertion port 6, the operator pushes baking rack 4-2, causing the caster wheel 4-3 to roll along the push-in guide rail 4-1, smoothly pushing baking rack 4-2 into the baking box 1.

[0043] like Figures 1-4 As shown in the figure, this embodiment proposes that a fan sleeve 3-7 be provided on the heat recovery cover 3-1, the fan sleeve 3-7 be embedded inside the heat recovery cover 3-1, and a heat recovery fan 3-8 be provided inside the fan sleeve 3-7.

[0044] In some examples, the fan sleeve 3-7 is pre-embedded inside the regenerator cover 3-1 and fixed by welding or tight interference fit. The regenerator fan 3-8 is installed inside the fan sleeve 3-7, and its motor shaft is firmly connected to the fan blades. When installing the regenerator fan 3-8, the inside of the fan sleeve 3-7 is first cleaned to ensure that there are no debris affecting the operation of the fan. Then, the regenerator fan 3-8 is placed in the fan sleeve 3-7 and the fan is fixed to the fan sleeve 3-7 by bolts or clips to ensure that the fan will not be displaced or shaken during operation. The power line of the regenerator fan 3-8 is connected to the electrical control system of the baking oven 1, and its speed and start / stop can be controlled by operating the adjustment knob 10 on the inclined surface 9.

[0045] like Figure 2 As shown, the side wall of the baking rack 4-2 has an insertion slot 4-4, and a display rack 4-5 is inserted into the insertion slot 4-4.

[0046] In some examples, the side wall of the baking rack 4-2 has an insertion slot 4-4. The rack 4-5 is designed and manufactured according to the size of the insertion slot 4-4. When installing the rack 4-5, the operator aligns the rack 4-5 with the insertion slot 4-4 and inserts it horizontally. The insertion depth is determined according to the design requirements of the rack 4-5, generally more than 95% of the depth of the insertion slot 4-4, to ensure that the rack 4-5 is installed firmly. When it is necessary to place cookie baking trays, the baking trays can be placed on the rack 4-5 one by one to achieve multi-layer baking and improve baking efficiency.

[0047] like Figure 1 As shown, a positioning frame 5 is provided on the inner side wall of the baking oven 1, and the positioning frame 5 is embedded inside the heating coil 2.

[0048] In some examples, the heating coil 2 is installed inside the baking oven 1, and the positioning frame 5 is pre-fixed to the inner wall of the baking oven 1 by welding or bolting. The positioning frame 5 is embedded inside the heating coil 2, which supports and positions the heating coil 2. When installing the heating coil 2, the positioning frame 5 is first installed at the corresponding position on the inner wall of the baking oven 1, and then the heating coil 2 passes through the positioning frame 5 according to the design path to ensure that the heating coil 2 is installed firmly and in an accurate position. The power supply of the heating coil 2 is connected to the electrical control system of the baking oven 1, and the heating power of the heating coil 2 can be controlled by adjusting the knob 10.

[0049] like Figure 1 As shown, the baking box 1 has an insertion port 6, the baking rack 4-2 is inserted into the insertion port 6, the insertion port 6 is provided with a placement strip 7, and a sealing buckle 8 is connected to the placement strip 7 by a pin.

[0050] In some examples, the insertion port 6 is located on the baking oven 1, and its size is adapted to the baking rack 4-2 to ensure that the baking rack 4-2 can be inserted smoothly. The mounting strip 7 is fixed to the edge of the insertion port 6 by welding or bolt connection. The sealing cover 8 is connected to the mounting strip 7 by a pin. When the baking rack 4-2 is not inserted, the sealing cover 8 is in the closed state, covering the insertion port 6 to prevent heat loss. When the baking rack 4-2 needs to be inserted, the operator opens the sealing cover 8, inserts the baking rack 4-2 into the insertion port 6, and then closes the sealing cover 8 to ensure the sealing of the insertion port 6. A sealing rubber gasket is provided between the sealing cover 8 and the insertion port 6. When the sealing cover 8 is closed, the rubber gasket is compressed to effectively prevent heat leakage.

[0051] like Figure 1 As shown, the baking oven 1 is connected to the mains power. The upper surface of the baking oven 1 is provided with a control slope 9, and an adjustment knob 10 is provided on the control slope 9.

[0052] In some examples, the baking oven 1 is connected to the mains power supply, the power cord is connected to the power interface of the baking oven 1, and electrical safety is ensured by a leakage protection device. The control ramp 9 is set on the upper surface of the baking oven 1 and adopts an inclined design for easy operation by the operator. The adjustment knob 10 is installed on the control ramp 9 and is connected to the electrical control system of the baking oven 1 through a line. The operator can control parameters such as the heating temperature of the baking oven 1 and the speed of the regenerating fan 3-8 by rotating the adjustment knob 10. One rotation of the adjustment knob 10 can make the heating temperature of the baking oven 1 change linearly between 50℃ and 250℃.

[0053] like Figure 3 As shown, a connecting pipe 11 is provided on the upper end face of the plug cover 3-4, and the connecting pipe 11 is sealed and plugged into the connecting pipe 3-3.

[0054] In some examples, the connecting pipe 11 is located on the upper end face of the plug cover 3-4 and is sealed to the connecting pipe 3-3. When connecting, first apply sealant to the plug joint of the connecting pipe 11 and the connecting pipe 3-3, and then slowly insert the connecting pipe 11 into the connecting pipe 3-3 to ensure that the insertion depth meets the design requirements, which is generally about 1.5 times the diameter of the connecting pipe 11, in order to ensure good sealing effect and connection strength.

[0055] When in use, after the baking oven 1 is connected to the mains power, the heating coil 2 starts working, converting electrical energy into heat energy, raising the internal temperature of the baking oven 1. The heat is evenly distributed within the baking oven 1, baking cookies placed on the baking rack 4-2. By operating the adjustment knob 10 on the inclined surface 9, the heating power of the heating coil 2 can be precisely adjusted according to the baking requirements of different types of cookies, thereby controlling the temperature inside the baking oven 1. The push-in guide rail 4-1 in the baking assembly 4 provides a stable moving track for the baking rack 4-2. The operator pushes the baking rack 4-2 with the cookie baking trays placed on it into the baking oven 1 through the insertion port 6. The moving wheels 4-3 at the lower end of the baking rack 4-2 roll on the push-in guide rail 4-1, making it convenient and labor-saving. The rack 4-5 on the baking rack 4-2 can hold multiple layers of cookie baking trays, improving baking efficiency. When the insertion port 6 is pushed into the baking rack 4-2, the placement strip 7 and sealing buckle 8 on the insertion port 6 can effectively seal the insertion port 6, reducing heat loss. When the cookies in the baking box 1 are baking, a large amount of hot air will be generated. The heat recovery cover 3-1 in the heat recovery plug assembly 3 collects the hot air at the top of the baking box 1. The heat recovery fan 3-8 is started. Under the action of the fan, the hot air enters the plug cover 3-4 through the plug pipe 3-2 and the connecting pipe 3-3. The plug cover 3-4 can be connected to an external heat recovery device, such as a heat exchanger. The hot air exchanges heat with the outside cold air in the heat exchanger, transferring heat to the cold air and raising the temperature of the cold air, realizing the recovery and utilization of heat. The design of the push spring 3-6 and the locking strip 3-5 ensures the firmness and sealing of the connection between the external heat recovery device and the plug cover 3-4, preventing hot air leakage.
