Description

Technical Field

[0001] This utility model relates to the field of sludge incineration treatment technology, and in particular to a sludge drying and incineration treatment device. Background Technology

[0002] With the development of society and economy and the improvement of people's living standards, the output of industrial wastewater and urban sewage is increasing day by day. During the sewage treatment process, a large amount of suspended matter is generated, which is collectively referred to as sludge. The composition of sludge is relatively complex. If it is piled up indiscriminately, it will have a great impact on the health of humans, animals and plants. Therefore, a sludge drying and incineration treatment device is needed to dry and incinerate sludge.

[0003] An existing sludge drying and incineration treatment device (publication number: CN222047746U) has at least the following drawbacks: the sludge needs to be dried before incineration to reduce its moisture content and increase incineration efficiency. However, in this device, the sludge is allowed to fall freely in a dispersion box and heated by hot air during this process. The heating time is too short, which does not allow the sludge to fully contact the hot air, resulting in low thermal energy utilization. Furthermore, it is difficult to ensure uniform heating of the sludge, which can cause local overheating or incomplete drying, thus affecting the subsequent incineration efficiency. Therefore, this invention is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for drying and incinerating sludge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sludge drying and incineration treatment device includes a treatment box, an incinerator is provided on the right side of the treatment box, and treatment components are provided on the top surface and inside the treatment box. The treatment components include a first conveying cylinder fixed to the top surface of the treatment box, a first conveying auger rotatably connected to the rear side of the interior of the first conveying cylinder, a belt conveyor installed inside the treatment box, the conveying end of the first conveying cylinder penetrating through the top surface of the treatment box and extending above the belt conveyor, a blower fixed to the rear side of the treatment box, and a heating box fixed to the air outlet end of the blower, the heating box being connected and fixed to the rear side of the treatment box.

[0007] As a further embodiment of this utility model, a first motor is fixed to the rear end of the first conveying cylinder, the output shaft of the first motor is fixed to the rear end of the first conveying auger, a feed pipe is fixed to the top surface of the first conveying cylinder, several heating pipes are fixed inside the heating box, a second conveying cylinder is fixed to the bottom surface of the processing box near the rear side, a second conveying auger is rotatably connected to the left side inside the second conveying cylinder, a second motor is fixed to the left side of the second conveying cylinder, the second motor is fixed to the left end of the second conveying auger, and the right end of the second conveying cylinder is installed at the feed inlet of the incinerator.

[0008] As a further embodiment of this invention, a crushing roller is fixed to the front end of the first conveying auger.

[0009] As a further embodiment of this utility model, a moisture recovery pipe is connected to and fixed on the front side of the processing box, and the moisture recovery pipe is connected to the moisture treatment system on the outer wall.

[0010] As a further embodiment of this utility model, a material spreading plate is installed inside the processing box and above the belt conveyor, with a gap of 15 to 20 cm between the material spreading plate and the top surface of the belt conveyor.

[0011] As a further embodiment of this utility model, a scraper is fixed inside the processing box and below the belt conveyor, and the scraper abuts against the bottom surface of the belt conveyor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Hot air is supplied to the processing chamber via a blower and heating box. The first conveyor conveyor transports the sludge to the top of the belt conveyor. The sludge is then transported along a path opposite to the direction of the hot air flow, allowing it to gradually receive gradient heating during transport. This ensures that the sludge and hot air are in full contact, significantly improving the utilization rate of thermal energy. At the same time, the reverse conveying design allows the moisture in the sludge to evaporate layer by layer. Compared with traditional unidirectional conveying, the sludge is heated more evenly and for a longer time, avoiding problems such as local overheating or incomplete drying. In addition, the belt conveyor combined with gradient heating effectively prevents the sludge from clumping due to local high temperatures during the drying process, improving the convenience of subsequent processing.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-4As shown, a sludge drying and incineration treatment device includes a treatment box 1. An incinerator 101 is arranged on the right side of the treatment box 1. Treatment components are arranged on the top surface and inside the treatment box 1. The treatment components include a first conveying cylinder 2 fixed on the top surface of the treatment box 1. A first conveying auger 201 is rotatably connected to the rear side of the interior of the first conveying cylinder 2. A belt conveyor 202 is installed inside the treatment box 1. The conveying end of the first conveying cylinder 2 passes through the top surface of the treatment box 1 and extends above the belt conveyor 202. A blower 203 is fixed to the rear side of the treatment box 1. A heating box 204 is fixed to the air outlet end of the blower 203. The heating box 204 is connected and fixed to the rear side of the treatment box 1.

[0023] like Figures 2-4 As shown, in this embodiment, a first motor is fixed to the rear end of the first conveying cylinder 2, and the output shaft of the first motor is fixed to the rear end of the first conveying auger 201. A feed pipe 205 is fixedly connected to the top surface of the first conveying cylinder 2. Several heating pipes 206 are fixed inside the heating box 204. A second conveying cylinder 207 is fixedly connected to the bottom surface of the processing box 1 near the rear side. A second conveying auger 208 is rotatably connected to the left side of the inside of the second conveying cylinder 207. A second motor is fixed to the left side of the second conveying cylinder 207, and the second motor is fixed to the left end of the second conveying auger 208. The right end of the second conveying cylinder 207 is installed at the feed inlet of the incinerator 101. By continuously discharging the sludge to be incinerated into the inside of the first conveying cylinder 2 through the feed pipe 205, the first motor is then started to drive the first conveying auger 201 and the crushing roller 3 to rotate together. The first conveying auger 201 continuously conveys the sludge, which then falls into the belt conveyor 202. Above, belt conveyor 202 transports sludge to the rear of treatment box 1. During this process, blower 203 starts and inputs airflow into heating box 204. After being heated by heating pipe 206, the airflow flows in the opposite direction to the sludge transport, so that the sludge is gradually heated during the transport process, allowing the sludge to fully contact the hot air and significantly improving the thermal energy utilization rate. At the same time, the reverse conveying design allows the moisture of the sludge to evaporate layer by layer. Compared with traditional unidirectional conveying, the sludge is heated more evenly and for a longer time, avoiding the problems of local overheating or incomplete drying. In addition, belt conveyor 202 combined with gradient heating effectively prevents the sludge from clumping due to local high temperature during the drying process, improving the convenience of subsequent processing. The heated sludge is transported into the second conveying cylinder 207, and then the second motor is started to drive the second conveying auger 208 to rotate, so that the sludge is transported to incinerator 101 for incineration.

[0024] like Figures 2-4 As shown in this embodiment, a crushing roller 3 is fixed at the front end of the first conveying auger 201. By setting the crushing roller 3, when the sludge is conveyed to the crushing roller 3, the large-volume clumps in the sludge are crushed by the crushing roller 3, thereby increasing the drying effect on the sludge.

[0025] like Figures 2-4 As shown in this embodiment, the front side of the treatment box 1 is connected to and fixed with a moisture recovery pipe 4. The moisture recovery pipe 4 is connected to the moisture treatment system on the outer wall. By setting the moisture recovery pipe 4, the moisture during the drying of sludge can be conveniently exported, recycled and reprocessed.

[0026] like Figures 2-4 As shown in this embodiment, a spreading plate 5 is installed inside the processing box 1 and above the belt conveyor 202. The spreading plate 5 has a gap of 15 to 20 cm with the top surface of the belt conveyor 202. By setting the spreading plate 5, the sludge can be continuously scraped and spread during sludge conveying, increasing the heat-receiving area of ​​the sludge.

[0027] like Figures 2-4 As shown in this embodiment, a scraper 6 is fixed inside the processing box 1 and below the belt conveyor 202. The scraper 6 abuts against the bottom surface of the belt conveyor 202. By setting the scraper 6, the bottom of the belt conveyor 202 is scraped to prevent the dried sludge from sticking to the belt of the belt conveyor 202.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the sludge to be incinerated is continuously discharged into the interior of the first conveying cylinder 2 from the feed pipe 205. Then, the first motor is started to drive the first conveying auger 201 to rotate in tandem with the crushing roller 3. The first conveying auger 201 continuously conveys the sludge. When the sludge is conveyed to the crushing roller 3, the large lumps in the sludge are crushed by the crushing roller 3. Then, the sludge falls above the belt conveyor 202. The belt conveyor 202 conveys the sludge to the rear of the treatment box 1. During this process, the blower 203 is started to input airflow into the heating box 204. After being heated by the heating pipe 206, the airflow flows in the opposite direction to the sludge conveying direction. During this process, the accumulated sludge is continuously scraped and flattened by the spreading plate 5, increasing the heating area of ​​the sludge, so that... During the conveying process, the sludge is gradually heated in a gradient manner, allowing it to fully contact the hot air and significantly improving the thermal energy utilization rate. At the same time, the reverse conveying design allows the moisture in the sludge to evaporate layer by layer. Compared with the traditional unidirectional conveying, the sludge is heated more evenly and for a longer time, avoiding the problems of local overheating or incomplete drying. In addition, the belt conveyor 202, combined with the gradient heating method, effectively prevents the sludge from clumping due to local high temperature during the drying process, improving the convenience of subsequent processing. The heated sludge is conveyed into the second conveying cylinder 207. During this process, the scraper plate 6 scrapes the bottom of the belt conveyor 202 to prevent the dried sludge from sticking to the belt of the belt conveyor 202. Then, the second motor is started to drive the second conveying auger 208 to rotate, so that the sludge is conveyed to the incinerator 101 for incineration.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
