Description

Technical Field

[0001] This utility model relates to the field of industrial drying equipment technology, specifically to a drying oven structure with integrated waste gas recovery pipeline. Background Technology

[0002] In industrial production, material drying is an indispensable and crucial process in many fields such as chemical engineering, building materials, metallurgy, and food processing. Rotary dryers are widely used due to their advantages such as large processing capacity, strong adaptability, and uniform drying. Their basic principle is that the slow rotation of the furnace body causes the material to be continuously agitated by the internal lifting plates, ensuring full contact with the high-temperature hot air generated by the burner, thereby achieving moisture evaporation and material drying. However, this process generates a large amount of high-temperature waste gas, which not only carries considerable waste heat energy but also contains pollutants such as dust.

[0003] However, there are significant shortcomings in the existing technology: First, most traditional drying ovens lack effective waste heat recovery design, and the exhaust gas is directly discharged after simple dust removal, resulting in a large amount of heat energy being wasted; Second, even if there is a waste heat utilization system, it is mostly an external type, loosely connected to the main equipment, with complex pipelines and poor sealing, which easily causes heat loss and leakage; Third, the burner at the feed end is usually fixed, which is not conducive to maintenance and cleaning, while this utility model adopts a movable trolley design, which existing equipment generally does not have this flexibility.

The output shaft of the drive motor 212 drives the drive gear 213 to rotate, the drive gear 213 meshes with the rotating gear 214 to rotate, and the rotating gear 214 drives the furnace wall 216 to rotate. This provides a stable drive function to ensure the smooth rotation of the furnace wall 216.

[0039] Specifically, the auxiliary rotating assembly 22 includes: an auxiliary base 221 located on both sides of the motor base 211; an auxiliary rotating seat 222 disposed on the top of the auxiliary base 221, and four sets thereof; a support roller 223 rotatably disposed on both sides of the top of the auxiliary base 221, and rotating between two sets of auxiliary rotating seats 222 via a rotating shaft; and a tire 224 disposed on both sides of the outer wall of the furnace wall 216, and rotating in contact with the support roller 223.

[0040] In a preferred embodiment, the auxiliary base 221 has a rectangular structure. The tires 224 are made of high-strength refractory material. The tires 224 at both ends of the furnace wall 216 cooperate with the support rollers 223 on both sides of the bottom to ensure the smooth rotation of the furnace wall 216. This provides a stable auxiliary rotation function to ensure the smooth rotation of the furnace wall 216.

[0041] Example 2:

[0042] Based on Example 1, in order to provide efficient feeding and drying functions, a feeding assembly 31 is provided on one side of the power assembly 21.

[0043] Specifically, the feeding assembly 31 includes: a support base 311, located on top of the ground 1 and on one side of a set of auxiliary bases 221; a heating cylinder 312, located on top of the support base 311, with one end sleeved on one end of the furnace wall 216; a feeding funnel 313, located on top of the heating cylinder 312; a guide plate 314, located inside the heating cylinder 312 and below the feeding funnel 313; a first rotating ring 315, located on the outer wall of one side of the furnace wall 216 and rotating inside one side of the heating cylinder 312; a first rotating wheel 316, located on the inner wall of one side of the heating cylinder 312, with multiple sets arranged around it, and the outer wall of the first rotating ring 315 rotating together; a trolley 317, moving horizontally on the other side of the heating cylinder 312, with push wheels on both sides of the bottom of one end and universal wheels on both sides of the bottom of the other end; and a burner 318, located on top of the trolley 317, with the heat-spraying end extending into the other end of the heating cylinder 312.

[0044] In this embodiment, the support base 311 has a rectangular structure. The heating cylinder 312 is made of high-strength refractory material. The feeding hopper 313 is made of high-strength refractory material. The guide plate 314 is made of high-strength refractory material. The material enters the heating cylinder 312 through the feeding hopper 313 and slides down to the inside of one side of the furnace wall 216 via the guide plate 314. The trolley 317 moves to one end of the heating cylinder 312, and the burner 318 sprays high-temperature flames to generate hot air to dry the material. This provides efficient feeding and drying functions, ensuring smooth material processing.

[0045] Specifically, the discharge assembly 32 includes: a discharge baffle 321, sleeved on the other end of the furnace wall 216; a second rotating ring 322, disposed on the outer wall of the other end of the furnace wall 216, and rotating on the inner wall of one side of the discharge baffle 321; a second rotating wheel 323, disposed on the inner wall of one side of the discharge baffle 321, and multiple sets are arranged around it, with the outer wall attached to the second rotating ring 322 for rotation; and a discharge base 324, disposed on the top of the ground 1, and located at the bottom of the discharge baffle 321.

[0046] With this configuration, the discharge baffle 321 is made of high-strength refractory material. Material slides from the bottom discharge port of the discharge baffle 321 at one end of the furnace wall 216 onto the discharge base 324 and exits. This provides efficient discharge functionality, ensuring smooth material discharge.

[0047] Example 3:

[0048] Based on Example 2, in order to provide efficient waste gas recovery, an exhaust assembly 41 and a heat exchange assembly 42 are installed on one side of the top of the ground 1.

[0049] Specifically, the exhaust assembly 41 includes: a fan 411, which is installed at the top of the ground 1 and located on one side of the motor base 211; a first exhaust pipe 412, with one end flange-sealed to the intake end of the fan 411; a dust collector 413, which is installed at the top of the ground 1 and located on one side of the fan 411, with the other end flange-sealed to the exhaust end of the dust collector 413; and a second exhaust pipe 414, with one end flange-sealed to the inlet end of the dust collector 413 and the other end flange-sealed to one side of the discharge baffle 321.

[0050] The blower 411 is a high-efficiency centrifugal blower. Exhaust gas inside the furnace wall 216 enters the dust collector 413 for dust removal through the second extraction pipe 414, and then enters the blower 411 through the first extraction pipe 412. This provides efficient exhaust gas recovery and dust removal functions, reducing environmental pollution.

[0051] Specifically, the heat exchange assembly 42 includes: a heat exchanger 421, disposed on one side of the motor base 211 and on the other side of the fan 411; an air outlet pipe 422, with one end flange-sealed to the air outlet of the fan 411 and the other end flange-sealed to the air inlet of the heat exchanger 421; an exhaust pipe 423, with one end flange-sealed to the exhaust port of the heat exchanger 421; a water inlet pipe 424, with one end flange-sealed to the water inlet of the heat exchanger 421; a water pump 425, disposed on one side of the heat exchanger 421 and connected to the water outlet of the heat exchanger 421 via a pipe; an outlet pipe 426, with one end flange-sealed to the water outlet of the water pump 425; and a water storage tank 427, disposed at one end of the water pump 425, with the other end flange-sealed to the water inlet of the water storage tank 427.

[0052] In this embodiment, the heat exchanger 421 employs a high-efficiency plate heat exchanger. Exhaust gas enters the heat exchanger 421 through the exhaust pipe 422, where it exchanges heat with the water source. The cooled exhaust gas is then discharged through the exhaust pipe 423. The heated water flows through the water pump 425 and the outlet pipe 426 to the water storage tank 427 for storage. This provides a highly efficient heat exchange function, enabling heat reuse and improving energy efficiency.

[0053] In actual use, the user first pours the material to be dried into the feed hopper 313, then the material enters the heating cylinder 312, and then slides down the guide plate 314 to the inside of one side of the furnace wall 216. At the same time, the user pushes the trolley 317, and the push wheels and casters at the bottom of the trolley 317 move to one end of the heating cylinder 312, extending the heat-spraying end of the discharge base 324 into one end of the heating cylinder 312. Then the user locks the casters. Next, the user starts the burner 318 to spray high-temperature flames to generate hot air to dry the material. At the same time, the user starts the drive motor 212, and the output shaft of the drive motor 212 drives the drive gear 213 to rotate. The drive gear 213 meshes with... The rotating gear 214 rotates, which drives the furnace wall 216 to rotate. The wheel belts 224 at both ends of the furnace wall 216 rotate in conjunction with the bottom support rollers 223 on both sides. The lifting plates inside the furnace wall 216 stir up the material and slowly move it towards the discharge block 321. The two ends of the furnace wall 216 respectively drive the first rotating ring 315 and the second rotating ring 322 to rotate on the inner walls of the heating cylinder 312 and the discharge block 321. The first rotating wheel 316 and the second rotating wheel 323 rotate in conjunction with the first rotating ring 315 and the second rotating ring 322 respectively. Finally, the material slides from the discharge port at the bottom of the discharge block 321 at one end of the furnace wall 216 onto the discharge base 324 and comes out. Next, the user starts the blower 411. The exhaust gas inside the furnace wall 216 enters the dust collector 413 for dust removal through the second exhaust pipe 414. Then, the exhaust gas enters the blower 411 through the first exhaust pipe 412, and then enters the exhaust pipe 422 through the exhaust port of the blower 411. Then, it enters the heat exchanger 421. At this time, the user starts the heat exchanger 421. The external water inlet device adds water to the heat exchanger 421 through the water inlet pipe 424. The exhaust gas completes heat exchange with the water inside the heat exchanger 421. Then, the cooled exhaust gas is discharged to the exhaust gas treatment equipment through the exhaust pipe 423. Next, the user starts the water pump 425 to flow the heated water through the water outlet pipe 426 into the water storage tank 427 for storage. When hot water is needed, the water outlet at the bottom of the water storage tank 427 is opened to discharge the water.
