[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Reference Figure 1-4 , please refer to Figure 1-Figure 4 ,in, Figure 1 A schematic diagram of the three-dimensional structure of a feed processing waste heat recovery device proposed in the utility model Figure 1 ; Figure 2 A schematic diagram of the three-dimensional structure of a feed processing waste heat recovery device proposed in the utility model Figure 2 ; Figure 3 A three-dimensional structural schematic diagram of a waste heat recovery mechanism of a feed processing waste heat recovery device proposed by the utility model; Figure 4 The present invention is a schematic diagram of a three-dimensional cross-section structure of a waste heat recovery mechanism of a feed processing waste heat recovery device. A feed processing waste heat recovery device comprises: a feed processing oven 1, a wind cavity 3 is installed on the left side of the feed processing oven 1, and a hot air blower 4 is installed on the wind cavity 3. It should be noted that the wind cavity 3 is a rectangular cavity structure, and a number of hot air blowers 4 are evenly distributed along the side wall of the wind cavity 3; a waste heat recovery mechanism 9 is arranged on the right side of the feed processing oven 1, and a box door 2 is rotatably installed on the front side of the feed processing oven 1, and a handle is arranged on the box door 2.

[0022] By the above-mentioned arrangement, the rectangular cavity structure design of the air cavity 3 enables the hot air generated by the hot air blower 4 to be evenly blown into the feed processing oven 1 under the guidance of the air cavity 3, so that the drying of the feed is more uniform, thereby ensuring the uniformity of the drying quality in the feed drying production.

[0023] In the present embodiment, the waste heat recovery mechanism 9 comprises a mounting frame 91 and a heat recovery water tank 92, a sealing plate 95 is fixedly connected between the mounting frame 91 and the heat recovery water tank 92, a water supply pipe 93 and a water outlet pipe 94 are installed on the upper side of the heat recovery water tank 92, a plurality of air outlet pipes 96 are installed inside the heat recovery water tank 92, a through opening is provided at the connection between the feed processing oven 1 and the mounting frame 91, the through opening passes through the side wall of the feed processing oven 1, the cross-section shape of the air outlet pipe 96 is a rhombus, the air outlet pipe 96 is arranged downward in a curved arc along the inside of the heat recovery water tank 92, and the air outlet pipe 96 passes through the heat recovery water tank 92.

[0024] Through the arrangement in the above manner, when the hot air blower 4 blows hot air into the feed processing oven 1 through the wind chamber 3, the hot air flow flowing to the side of the feed processing oven 1 still retains residual heat, and the residual heat flows to the air outlet pipe 96 through the opening, and the heat is transferred to the water stored in the heat energy recovery water tank 92 through the pipe wall of the air outlet pipe 96, so that the water temperature in the heat energy recovery water tank 92 increases. Under the continuous action of the residual heat, high-temperature hot water is generated in the heat energy recovery water tank 92, and the high-temperature hot water is discharged through the outlet pipe and can be used for municipal heating or process heating, thereby avoiding the waste of residual heat.

[0025] In this embodiment, a plurality of bolts 97 are provided on the mounting frame 91 , and the heat recovery water tank 92 is screwed and mounted on the side of the feed processing oven 1 through the mounting frame 91 .

[0026] Through the above-mentioned arrangement, the entire waste heat recovery mechanism 9 is fixed on the feed processing oven 1 by screwing the mounting frame 91, which is convenient for later disassembly and maintenance.

[0027] In this embodiment, a reflux groove 5 is provided at the lower side of the heat recovery water tank 92, a water pump 6 is installed on the side of the reflux groove 5, a water pump 7 and a water supply pipe 8 are connected and installed on the water pump 6, the water pump 7 is connected to the inner side of the reflux groove 5, and the upper end of the water supply pipe 8 is connected to the inside of the heat recovery water tank 92, and the reflux groove 5 is a rectangular water storage tank.

[0028] Through the arrangement in the above manner, when the waste heat airflow that has undergone drying flows in the air outlet pipe 96, since the water stored in the heat recovery water tank 92 is equivalent to a lower temperature of the waste heat airflow, the moisture in the waste heat airflow is cooled and liquefied to generate water flow. Since the air outlet pipe 96 is arranged downward in a curved arc along the inside of the heat recovery water tank 92, the generated water flow flows along the arc slope of the air outlet pipe 96 and finally falls into the reflux groove 5 at the bottom of the heat recovery water tank 92. By starting the water pump 6 on the side of the reflux groove 5, the water flow gathered in the reflux groove 5 can be transported to the heat recovery water tank 92 through the pumping pipe 7 and the water supply pipe 8, thereby improving the utilization rate of water resources.

[0029] The working principle of a feed processing waste heat recovery device provided by the utility model is as follows:

[0030] When in use, the feed is placed in the feed processing oven 1, the oven door 2 is closed, and the hot air blower 4 is started. When the hot air blower 4 is working, high-temperature hot air is generated, and the high-temperature hot air is transported to the feed processing oven 1 through the wind chamber 3. The high-temperature hot air acts on the feed, taking away the moisture in the feed. The wind flow flowing through the side of the feed processing oven 1 still has a certain amount of heat, so the waste heat wind flow flows to the air outlet pipe 96 through the opening opened on the side wall of the feed processing oven 1, and is discharged to the outside through the air outlet pipe 96. When the waste heat wind flow flows in the air outlet pipe 96, its heat is transferred to the water stored in the heat energy recovery water tank 92 through the pipe wall of the air outlet pipe 96. Under the heat transfer, the heat energy recovery water tank When the temperature of the water stored in 92 rises, the high-temperature hot water generated in the heat recovery water tank 92 can be discharged through the outlet pipe 94 and used for municipal heating or process heating, helping enterprises to achieve energy conservation and emission reduction goals; at the same time, the waste heat airflow carries water vapor brought out when drying feed. Since the water stored in the heat recovery water tank 92 is equivalent to the waste heat airflow with a lower temperature, the water vapor in the waste heat airflow is cooled and liquefied to generate water flow. The generated water flow flows along the arc slope of the outlet pipe 96 and finally falls into the reflux groove 5 at the bottom of the heat recovery water tank 92. The water pump 6 is started to transport the water gathered in the reflux groove 5 to the heat recovery water tank 92 through the pumping pipe 7 and the water supply pipe 8, thereby improving the utilization of water resources.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
