Description

Technical Field

[0001] This utility model relates to the field of sludge treatment devices, and in particular to an air circulation and purification device. Background Technology

[0002] Sludge drying equipment typically uses a chain conveyor within a drying chamber. Sludge is directly fed onto the chain conveyor through the inlet, where it circulates and comes into full contact with the hot air, causing the sludge to lose moisture. However, this moisture loss generates a large amount of dust within the drying chamber. A purification device is usually used to absorb and treat this dust before returning clean hot air to the drying chamber. However, as the sludge loses moisture, some sludge hardens on the surface of the chain conveyor. Even with a purification device, some dust remains in the drying chamber due to this hardened sludge. Because this hardened sludge circulates repeatedly and is difficult to remove, it persists regardless of the purification device's efforts, affecting the degree of sludge drying. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an air circulation and purification device.

[0004] This utility model is achieved using the following technical solution: an air circulation and purification device, comprising a drying box, a circulation component, a purification component, and a vibration component. The drying box has an air inlet and an air outlet. The ends of the circulation component are respectively connected to the air inlet and the air outlet. The purification component is disposed on the circulation component, and the circulation component drives the hot air in the drying box to flow into the purification component from the air outlet. After the air inlet flows back to the drying box through the purification component, the air inlet flows back to the drying box. The drying box is provided with a conveyor chain plate. The vibration component is disposed inside the drying box and moves with the conveyor chain plate. The vibration component strikes the conveyor chain plate.

[0005] The conveyor chain includes a conveyor plate and a conveyor sprocket. The conveyor sprocket is rotatably connected to the inner wall of the drying chamber via a rotating shaft. One end of the vibrating assembly is driven by the rotating shaft. When the rotating shaft rotates, it causes the other end of the vibrating assembly to move away from or towards the conveyor plate. When the other end of the vibrating assembly approaches the conveyor plate, the vibrating assembly abuts against the conveyor plate.

[0006] The vibrating assembly includes a vibrating hammer, a driven shaft, a drive half gear, and a driven half gear. The driven shaft is rotatably connected to the inner wall of the drying chamber. The drive half gear is coaxially sleeved on the rotating shaft. The driven half gear is sleeved on the driven shaft, and the drive half gear and the driven half gear mesh with each other. The vibrating hammer is mounted on the driven shaft and is driven to rotate by the driven shaft.

[0007] The vibratory hammer includes a hammer head and a hammer handle. One end of the hammer handle is fixed to the hammer head, and the other end of the hammer handle is fixed to the driven shaft. The hammer handle extends along the length of the conveyor chain plate. When the driving half gear meshes with the driven half gear, the hammer head is raised. When the driving half gear and the driven half gear do not mesh, the hammer head strikes the conveyor chain plate.

[0008] The purification component includes a condenser, a heating section, and a dust removal section. The heating section is connected to the circulation component. The airflow drawn out by the circulation component flows sequentially through the dust removal section, the condenser, and the heating section, and is then returned to the drying chamber by the circulation component.

[0009] The condensation section includes several condenser tubes and cooling components. Air ducts are provided between the several condenser tubes for air to pass through. The air ducts are arranged along the airflow direction. Several guide grooves are opened on the inner wall of the air ducts. Guide holes are opened at the bottom of the guide grooves. The guide holes are connected to the cooling components. The cooling components are connected to the condenser tubes and pump cooling water into the condenser tubes.

[0010] The cooling component includes a water tank, a water pump is installed inside the water tank, one end of the condenser tube is connected to the water tank and one end of the condenser tube is connected to the water pump, and the guide hole is connected to the water tank through a flexible hose.

[0011] The heating section includes several heating tubes and a housing. The heating tubes are disposed in the housing, and an air passage is formed between the heating tubes for airflow. When the air flows through the air passage, it is heated by the heating tubes.

[0012] The dust removal unit includes a housing, inside which is a dust removal box. The first air duct is inserted into the housing and extends into the dust removal box, which is placed below the water surface. The housing is connected to the condensation unit.

[0013] Compared to existing technologies, this invention continuously vibrates the conveyor chain during its movement, knocking off dirt adhering to the chain. This dirt is then circulated into the purification unit with hot air and cleaned, resulting in a cleaner conveyor chain and less dust generation during subsequent transport. The drying effect is also improved. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Reference Figure 1-7An air circulation and purification device includes a drying chamber 1, a circulation component 2, a purification component 3, and a vibration component 4. The drying chamber 1 has an air inlet and an air outlet. The ends of the circulation component 2 are connected to the air inlet and the air outlet, respectively. The purification component 3 is mounted on the circulation component 2, and the circulation component 2 drives the hot air in the drying chamber 1 to flow into the purification component 3 through the air outlet. The air then flows back to the drying chamber 1 through the air inlet from the purification component 3. In this design, the purification component 3 includes a condenser 32, a heating component 33, and a dust removal component 31. The heating component 33 is connected to the circulation component 2. The airflow drawn from the circulation component 2 flows sequentially through the dust removal component 31, the condenser 32, and the heating component 33, and is then returned to the drying chamber 1 by the circulation component 2. The circulation component 2 can be an axial flow fan 21, which is located on one side of the heating section 33. This allows the hot air drawn back from the drying chamber 1 to pass sequentially through the dust removal section 31 and the condenser section 32, forming relatively clean air with a slightly lower temperature. After being heated by the heating section 33, the hot air is then returned to the drying chamber 1 via the axial flow fan 21. In this embodiment, the dust removal section 31 includes a housing with a dust collection box 311 inside. A first air duct 312 is inserted into the housing and extends into the dust collection box 311, positioned below the water surface. The housing is connected to the condenser section 32. Air flowing through the dust removal section 31 is sent below the water surface in the dust collection box 311 via the first air duct 312. Dust carried within the dust collection box enters and remains in the dust collection box 311. The gas then enters the condenser section 32 for dehydration. The condenser section 32 includes a plurality of condenser tubes 321 and a cooling component. Air ducts are provided between the condenser tubes 321 for air to pass through. The air ducts are arranged along the airflow direction. A plurality of guide grooves are formed on the inner wall of the air ducts, and guide holes are formed at the bottom of the guide grooves. The guide holes communicate with the cooling component, which is connected to the condenser tubes 321 and pumps cooling water into the condenser tubes 321. The cooling component includes a water tank 322, which contains a water pump. One end of each condenser tube 321 is connected to the water tank 322, and one end of each condenser tube 321 is connected to the water pump. The guide holes are connected to the water tank 322 via flexible hoses. The heating unit 33 in this embodiment includes several heating tubes 331 and a housing 332. The heating tubes 331 are located inside the housing 332. An air passage is formed between the several heating tubes 331 for airflow. When the air flows through the air passage, it is heated by the heating tubes 331 to restore the hot air to the temperature required inside the drying chamber 1.

[0024] The drying chamber 1 is also equipped with a conveyor chain plate 5. A vibrating assembly 4 is located inside the drying chamber 1 and moves with the conveyor chain plate 5, striking the conveyor chain plate 5. The conveyor chain plate 5 includes a conveyor plate 51 and a conveyor sprocket 52. The conveyor sprocket 52 is rotatably connected to the inner wall of the drying chamber 1 via a rotating shaft. One end of the vibrating assembly 4 is driven by the rotating shaft. When the shaft rotates, it causes the other end of the vibrating assembly 4 to move away from or towards the conveyor plate 51. When the other end of the vibrating assembly 4 approaches the conveyor plate 51, the vibrating assembly 4 abuts against the conveyor plate 51. During the movement of the conveyor chain plate 5, the vibrating assembly 4 continuously vibrates the conveyor chain plate 5, knocking off the dirt adhering to it. This dirt then enters the purification assembly 3 with the circulating hot air and is purified. At this point, the conveyor chain plate 5 is clean, reducing the amount of dust generated during subsequent conveying and improving the drying effect.

[0025] The vibrating assembly 4 in this embodiment includes a vibrating hammer 41, a driven shaft, a drive half gear 42, and a driven half gear 43. The driven shaft is rotatably connected to the inner wall of the drying chamber 1. The drive half gear 42 is coaxially sleeved on the rotating shaft, and the driven half gear 43 is sleeved on the driven shaft, with the drive half gear 42 and the driven half gear 43 meshing with each other. The vibrating hammer 41 is mounted on the driven shaft and is driven to rotate by the driven shaft. The vibrating hammer 41 includes a hammer head 411 and a hammer handle 422. One end of the hammer handle 422 is fixed to the hammer head 411, and the other end of the hammer handle 422 is fixed to the driven shaft. The hammer handle 422 extends along the length of the conveyor chain plate 5. When the drive half gear 42 meshes with the driven half gear 43, the hammer head 411 is raised. When the drive half gear 42 and the driven half gear 43 are not meshed, the hammer head 411 strikes the conveyor chain plate 5. When the driving half gear 42 meshes with the driven half gear 43, the driven shaft rotates and the hammer handle 422 is lifted. When the driven half gear 43 rotates to the toothless side, it falls naturally due to the weight of the hammer head 411. This process is repeated to repeatedly hammer the conveyor chain plate 5, knocking off the sludge that has hardened on the conveyor chain plate 5, making it easier to process.

[0026] Compared to existing technologies, this invention continuously vibrates the conveyor chain 5 during its movement, knocking off dirt adhering to it. This dirt is then circulated into the purification component 3 by hot air and purified. As a result, the conveyor chain 5 is clean, reducing dust generation during subsequent transport and improving drying efficiency.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
