Description

Technical Field

[0001] This utility model relates to the technical field of sludge dryers, and in particular to a sludge dryer with good drying effect. Background Technology

[0002] With the rapid pace of industrialization and urbanization, the production of sewage sludge is increasing dramatically. Sludge is rich in moisture, organic matter, heavy metals, and pathogens. Improper disposal not only occupies valuable land resources but also poses a threat to soil, water, and air pollution, impacting the ecological environment and human health. Sludge drying, as a crucial step in sludge treatment, is undeniably important. Reducing the moisture content and volume of sludge through drying creates favorable conditions for subsequent disposal methods such as landfill, incineration, and resource utilization. Traditional dryers lack precise control over sludge conveying and mixing, resulting in inconsistent residence time and heating levels within the equipment. This leads to localized over-drying during the drying process, causing carbonization and quality degradation; while other areas are under-dryed, resulting in excessively high moisture content that fails to meet subsequent treatment requirements. The inconsistency in drying effect affects the final treatment quality and resource utilization value of sludge. In addition, the drying process generates a large amount of waste gas containing dust, acidic gases, odorous substances and other pollutants. However, most traditional equipment lacks effective waste gas purification measures. These waste gases are directly discharged into the atmosphere without treatment, causing secondary pollution to the surrounding environment. Therefore, we propose a sludge dryer with good drying effect to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a sludge dryer with good drying effect to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sludge dryer with good drying effect includes: a housing, a storage tank and a shell fixedly installed inside the top of the housing, a crushing assembly inside the storage tank, the crushing assembly including: two sets of stirring shafts, multiple sets of collars fixedly installed on the outer sides of the two sets of stirring shafts, and multiple sets of crushing blades fixedly installed on the outer sides of the multiple sets of collars; augers rotatably installed on the inner walls of both sides of the housing; and a drying assembly inside the shell, the drying assembly including: a rotating shaft and two sets of connecting shafts, both sets of connecting shafts rotatably extending to the top of the housing. Two bevel gears and a fan are fixedly installed at both ends of the shaft, respectively. Two sets of bevel gears are fixedly installed on the outer side of the shaft, and the two sets of bevel gears mesh with the corresponding bevel gears. A heating plate is provided at the bottom of the two sets of fans. A dust collection hood is provided inside the housing. A connecting pipe is fixedly installed on one side of the dust collection hood and extends through to one side of the housing. An air pump is fixedly installed at one end of the connecting pipe. An air pipe is fixedly installed at the bottom of the air pump. An exhaust gas treatment box is fixedly installed at one end of the air pipe. A filter plate is fixedly installed inside the exhaust gas treatment box.

[0006] Preferably, the exhaust gas treatment box is equipped with a purification component, which includes: a water tank, the water tank being fixedly installed on one side of the exhaust gas treatment box, a short pipe and a water inlet pipe being fixedly installed on the top of the water tank, a pump body being fixedly installed on the top of the short pipe, a water outlet pipe being fixedly installed on the top of the pump body, the water outlet pipe penetrating into the interior of the exhaust gas treatment box, and multiple diversion pipes being fixedly installed on the outside of the water outlet pipe, with spray heads fixedly installed at the bottom of each of the multiple diversion pipes.

[0007] Preferably, a motor frame and a second motor are fixedly installed on one side of the housing, a first motor is fixedly installed on the top of the motor frame, both sets of stirring shafts rotate through to one side of the housing, small gears are fixedly installed on the outer side of both sets of stirring shafts, the two sets of small gears mesh with each other, the output shaft of the first motor is fixedly connected to the stirring shaft located at the bottom, and the output shaft of the second motor is fixedly connected to the auger.

[0008] Preferably, two sets of short plates are fixedly installed on the top of the housing, and the rotating shaft is rotatably installed inside the two sets of short plates. A motor is fixedly installed on one side of the right short plate, and the output shaft of the motor is fixedly connected to the rotating shaft. The heating plate is fixedly installed on the inner walls of both sides of the housing, and an air outlet is provided at the bottom of the housing.

[0009] Preferably, a filter plate is fixedly installed inside the housing, the filter plate is located at the bottom of the auger, a discharge port is opened on one side of the filter plate, a discharge port is opened on one side of the housing, a discharge plate is provided inside the discharge port, and the discharge plate is fixedly connected to the filter plate.

[0010] Preferably, a feed hopper and an exhaust pipe are fixedly installed on the top of the box and the exhaust gas treatment box, respectively, and a drain pipe is fixedly installed on the bottom of the exhaust gas treatment box and the box.

[0011] In this utility model, a sludge dryer with good drying effect is provided. It is equipped with a crushing component and an auger. A drive motor drives the output shaft of the motor to drive the stirring shaft at the bottom to rotate. Since the small gears on the outer sides of the two stirring shafts mesh, the other stirring shaft will also rotate in the opposite direction. The collars and crushing blades on the two stirring shafts rotate with the shafts to crush the sludge in the storage tank. A drive motor drives the auger to rotate. During the rotation of the auger, the sludge is transported along the inner wall of the tank towards the discharge port. During the transport process, some of the water in the sludge will be filtered through the water filter plate and discharged from the drain pipe at the bottom of the tank. This can crush the sludge into small particles, which greatly increases the specific surface area of ​​the sludge. The water can evaporate from the inside of the sludge more quickly, thereby greatly shortening the drying time, improving the drying efficiency, and facilitating the transport of sludge.

[0012] This utility model describes a sludge dryer with good drying effect. It includes a drying component, a dust collection hood, a connecting pipe, an air pump, a filter plate, an exhaust gas treatment box, and a purification component. A drive motor drives a rotating shaft, causing two sets of bevel gears on the outer side of the rotating shaft to rotate. Since each set of bevel gears meshes with a corresponding bevel gear, the two connecting shafts drive the fans to rotate. The air pump is then turned on, drawing in exhaust gas containing dust and water vapor from inside the box through the connecting pipe. The gas first encounters the filter plate, which intercepts large dust particles in the exhaust gas. Water mist fully contacts the exhaust gas, further adsorbing and dissolving odorous substances and some soluble pollutants. The combined design of the two fans and the heating plate ensures that hot air is blown onto the sludge from different positions, guaranteeing uniform heating of the sludge. This effectively avoids the problem of localized over- or under-drying, ensuring consistent drying results and shortening drying time. Furthermore, the combination of filter plates and water mist spraying effectively removes pollutants from the exhaust gas, reducing environmental pollution and increasing the practicality of the device.

[0021] In this embodiment, a purification component 7 is installed inside the exhaust gas treatment box 6. The purification component 7 includes a water tank 701, which is fixedly installed on one side of the exhaust gas treatment box 6. A short pipe and a water inlet pipe are fixedly installed on the top of the water tank 701. A pump body 702 is fixedly installed on the top of the short pipe. A water outlet pipe 703 is fixedly installed on the top of the pump body 702. The water outlet pipe 703 extends into the interior of the exhaust gas treatment box 6. Multiple diversion pipes 704 are fixedly installed on the outside of the water outlet pipe 703. Spray heads 705 are fixedly installed at the bottom of each of the multiple diversion pipes 704 to facilitate the treatment of the exhaust gas generated during drying. The exhaust gas is effectively treated. A motor frame and a second motor 14 are fixedly installed on one side of the housing 1. A first motor 13 is fixedly installed on the top of the motor frame. Both sets of stirring shafts 301 rotate through to one side of the housing 1. Small gears 302 are fixedly installed on the outer side of both sets of stirring shafts 301. The two sets of small gears 302 mesh with each other. The output shaft of the first motor 13 is fixedly connected to the stirring shaft 301 located at the bottom. The output shaft of the second motor 14 is fixedly connected to the auger 4, which facilitates the rotation of the stirring shafts 301 and the auger 4, facilitates the transportation of sludge, and facilitates the crushing of sludge into smaller pieces.

[0022] In this embodiment, two sets of short plates are fixedly installed on the top of the housing 1. A rotating shaft 501 is rotatably installed inside the two sets of short plates. A motor 507 is fixedly installed on one side of the right short plate. The output shaft of the motor 507 is fixedly connected to the rotating shaft 501. Heating plates 506 are fixedly installed on the inner walls of both sides of the housing 17. An air outlet is provided at the bottom of the housing 17 to facilitate the rotation of the rotating shaft 501 and the two sets of fans 505. A water filter plate 15 is fixedly installed inside the housing 1. The water filter plate 15 is located within the auger 4. At the bottom, a discharge port is provided on one side of the filter plate 15, and a discharge port is provided on one side of the box body 1. A discharge plate 16 is provided inside the discharge port. The discharge plate 16 is fixedly connected to the filter plate 15 to facilitate the discharge of water from the initial filtration of sludge and the discharge of dried sludge. A feed hopper 2 and an exhaust pipe are fixedly installed on the top of the box body 1 and the exhaust gas treatment box 6, respectively. A drain pipe 12 is fixedly installed at the bottom of both the exhaust gas treatment box 6 and the box body 1 to facilitate the discharge of sewage, the addition of sludge to the storage box, and the removal of purified air.

[0023] In this embodiment, when sludge needs to be dried, it enters the storage tank from the feed hopper 2. The drive motor 13 drives the bottom stirring shaft 301 to rotate. Since the small gears 302 on the outer sides of the two stirring shafts 301 mesh, the other stirring shaft 301 also rotates in the opposite direction. The collars 303 and crushing blades 304 on the two stirring shafts 301 rotate with the shafts, crushing the sludge in the storage tank. During rotation, the multiple crushing blades 304 cut and crush the sludge from different angles, breaking larger sludge blocks into smaller particles, increasing the specific surface area of ​​the sludge, facilitating subsequent drying, and allowing the sludge to contact the hot air more fully, accelerating moisture evaporation. The crushed sludge falls from the storage tank into the auger 4, driven by the drive motor 12. 4. This causes the auger 4 to rotate. During the rotation of the auger 4, the sludge is conveyed along the inner wall of the box 1 towards the discharge port. During the conveying process, some of the water in the sludge will be filtered through the filter plate 15 and flow down, and discharged from the drain pipe 12 at the bottom of the box 1, thus achieving the initial dewatering of the sludge. The filter plate 15 can effectively separate the water in the sludge, reduce the burden of subsequent drying, and improve the drying efficiency. The drive motor 507 drives the output shaft to rotate the rotating shaft 501. The two sets of bevel gears 502 on the outside of the rotating shaft 501 rotate accordingly. Since the two sets of bevel gears 502 mesh with the corresponding bevel gears 503, the two sets of connecting shafts 504 will drive the fan 505 to rotate. Simultaneously, the heating plate 506 starts working, generating heat. The fan 505 rotates, blowing the heat generated by the heating plate 506 onto the sludge below. The hot air comes into full contact with the sludge, causing the moisture in the sludge to evaporate rapidly. Two sets of fans 505 blow air onto the sludge from different positions to ensure that the sludge is heated evenly, avoiding local over- or under-drying. Then, the air pump 10 is turned on, and air containing dust and water vapor is drawn into the exhaust gas inside the chamber 1 through the connecting pipe 9. The exhaust gas enters the exhaust gas treatment chamber 6 through the air pipe 11, first encountering the filter plate 18, which intercepts large dust particles in the exhaust gas. Next, water in the water tank 701 is pumped through the pump body 702, and sprayed out from the spray head 705 through the water outlet pipe 703 and the diversion pipe 704, forming a water mist. The water mist comes into full contact with the exhaust gas, further adsorbing and dissolving odor substances and some soluble pollutants in the exhaust gas. The purified gas is discharged from the exhaust pipe, achieving the purification treatment of the exhaust gas and reducing environmental pollution.
