Description

Technical Field

[0001] This utility model relates to the field of sludge purification technology, specifically a sludge odor purifier. Background Technology

[0002] Sludge is composed of solid matter in the original wastewater and solid matter generated during wastewater treatment. Sludge treatment is a process of reducing, stabilizing and rendering harmless sludge by concentrating, conditioning, dewatering, stabilizing, drying or incinerating it. In order to reduce the odor attached to the sludge during the sludge treatment process, purification equipment is usually used to treat the odor of the sludge.

[0003] A search revealed a patent document, CN202322598886.1, which discloses "An Environmentally Friendly Sludge Odor Purification Device." This device includes a treatment box, with a motor fixedly connected to one side of the box. The motor's output shaft is fixedly connected to a rotating shaft via a coupling. During the odor purification process, this device can dry the sludge, thereby accelerating the dissipation of odor from the sludge and speeding up the odor removal process. This further improves the odor purification efficiency and makes the device more convenient to use.

[0004] While this patented technology can dry sludge, in actual operation, it involves rotating a drying frame containing sludge using a motor, in conjunction with heating elements for drying. If the motor drives the frame too slowly, the overall fluidity of the sludge is poor, affecting drying efficiency. If the motor drives the frame too fast, the sludge will be thrown out due to significant centrifugal force, affecting the normal operation of the heating elements and causing excessive sludge to adhere to the inner wall of the treatment chamber, making cleaning difficult. Therefore, we propose a sludge odor purifier to solve the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this invention is to provide a sludge odor purifier to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge odor purifier, comprising a drying box, a drying cylinder fixedly installed inside the drying box, heat-conducting filters provided on both the front and rear sides of the drying cylinder, a feeding pipe fixedly connected to and communicating with the right side of the drying box, electric heating plates fixedly installed on both the front and rear sides of the inner wall of the drying box, two rotating rods rotatably connected to the inner side of the drying cylinder, a plurality of stirring rods fixedly connected to the surface of the rotating rods, and a deodorizing component fixedly connected to and communicating with the top of the left side of the drying box.

[0007] Furthermore, the drying cylinder is specifically formed by splicing and connecting two open-top cylinders. Several rotating rods located on the same side inside the drying cylinder have scrapers fixedly connected to one end, and the outer surface of the scrapers is in contact with the inner wall of the drying cylinder.

[0008] Furthermore, a transmission gear is fixedly connected to the top of the rotating rod extending to the outside of the drying box. The two transmission gears mesh with each other. A motor frame is also fixedly installed on the top of the drying box. A drive motor is fixedly installed on the upper surface of the motor frame. The output shaft end of the drive motor is fixedly connected to the center position of the top of one of the transmission gears.

[0009] Furthermore, a discharge pipe is fixedly connected to the right side of the drying cylinder and communicates with it. One end of the discharge pipe extends to the outside of the drying box, and a drain pipe is fixedly connected to the bottom of the drying box and communicates with it.

[0010] Furthermore, a filter frame is slidably connected to the inner wall of the drying chamber and below the drying cylinder, and a filter screen is installed on the filter frame. A baffle is fixedly connected to the right side of the drying chamber corresponding to the position of the filter frame by bolts.

[0011] Furthermore, the deodorization component includes a vent pipe, one end of which is fixedly connected to the drying oven, and the other end is fixedly connected to a cylindrical shell that communicates with it. The cylindrical shell is equipped with a deodorization filter element inside, and a cap is threadedly connected to the opening at the top of the cylindrical shell. An exhaust pipe that communicates with the top of the cap is fixedly connected to it.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows sludge to be deodorized and dried to be added into the drying cylinder via a feeding pipe. During drying, the heating plate is energized to provide the necessary heat. After the drive motor is turned on, its output shaft drives one of the transmission gears to rotate, and the other meshing transmission gear rotates synchronously, thereby driving two rotating rods to rotate synchronously. The stirring rod is used to fully stir the sludge, achieving a uniform drying effect in conjunction with the heat source, and accelerating the dissipation of odor from the sludge. The wastewater in the filtered sludge is discharged through the drain pipe after secondary filtration through the filter screen on the filter frame. The dried sludge is discharged through the discharge pipe. The high-temperature odor generated during the process enters the cylindrical shell through the vent pipe, where it is deodorized by the deodorizing filter element. Finally, the odorless drying gas is discharged from the exhaust pipe. This sludge odor purifier has a reasonable structural design and is easy to use. During the sludge drying process, it can achieve uniform flow and stirring of the sludge. With the continuous supply of heat source, it can effectively improve the drying efficiency of the sludge. Moreover, this process will not cause sludge to splash onto the inner wall of the equipment or onto the heating source, eliminating the need for cleaning steps. The high-temperature odor generated during the drying process can also be effectively purified and discharged to the outside, making it have a good performance. Attached Figure Description

A deodorizing component 8 is fixedly connected to the top left side of the drying box 1 and communicates with it. The deodorizing component 8 can purify and deodorize the high-temperature odor generated during the drying process.

[0017] The drying cylinder 2 is specifically formed by splicing and connecting two open-top cylinders.

[0021] The deodorizing component 8 includes a vent pipe 81, one end of which is fixedly connected to the drying chamber 1, and the other end is fixedly connected to a cylindrical shell 82 that is connected to it. A one-way valve is installed on the vent pipe 81. The high-temperature odor generated during the drying process can enter the cylindrical shell 82 through the vent pipe 81. The cylindrical shell 82 is equipped with a deodorizing filter element 83, which can effectively purify the odor. This is a mature existing technology and will not be described in detail here. A cover 84 is threadedly connected to the top opening of the cylindrical shell 82. The cover 84 is installed by means of threads. After the deodorizing filter element 83 has been used for a long time, the cover 84 can be removed and the deodorizing filter element 83 can be replaced. An exhaust pipe 85 is fixedly connected to the top of the cover 84 and is connected to it. The exhaust pipe 85 can discharge the gas that has been deodorized and purified.

[0022] This sludge odor purifier has a reasonable structural design and is easy to use. During the sludge drying process, it can achieve uniform flow and stirring of the sludge.
