Description

Technical Field

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

[0002] Sludge refers to mud-like waste generated during water treatment, mainly composed of organic matter. It is a semi-solid or solid substance formed after the suspended solids, colloidal substances and dissolved substances in the water are separated and aggregated through physical, chemical and biological methods during the treatment of sewage or wastewater. In order to facilitate the transportation and treatment of sludge, a sludge drying machine is required.

[0003] A search revealed Chinese patent publication number CN220245886U, which discloses a disc structure for a sludge dryer, including a shaft tube and a disc-shaped cover. The shaft tube axially penetrates and is welded to the center of the disc-shaped cover. Two disc-shaped covers are provided and welded to both sides of a central plate, respectively. The two disc-shaped covers are symmetrical about the central plate. A first vortex plate and a second vortex plate are welded to both sides of the central plate, respectively. The first vortex plate and the second vortex plate have opposite spiral directions and the same size. A circular through hole is provided in the center of the central plate, and a trumpet-shaped throttling nozzle is welded to one side of the through hole. The throttling nozzle is located at the center of the first vortex plate. The first and second vortex plates form a first flow channel and a second flow channel with the inner wall of the corresponding disc-shaped cover, respectively. The first and second flow channels are connected by air holes. High-temperature steam flows continuously through each disc, so the high-temperature steam heats the disc-shaped cover sufficiently. Moreover, the flowing steam heating helps the disc-shaped cover maintain a high temperature, thus improving the drying efficiency of sludge. However, during long-term use, the disc surface is in direct contact with the sludge, and friction caused by relative operation leads to wear, which can easily cause local wear and leakage, thereby affecting production and reducing the reliability of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sludge drying machine, which aims to improve the problem of easy wear of the disc structure in the existing sludge drying machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sludge drying machine, including a processing cylinder, a drying mechanism is provided on the inner side of the processing cylinder, the drying mechanism is used to improve drying efficiency and reduce wear, and a feeding mechanism is provided on the top of the processing cylinder, the feeding mechanism can improve the feeding and processing effect;

[0006] The drying mechanism includes a turntable, which is rotatably connected to the middle of the inner side of the processing cylinder. An air inlet hood is connected to the middle of the bottom end of the turntable. A heating wire is fixedly connected to the bottom of the inner side of the processing cylinder. Multiple protrusions are fixedly connected to the top of the turntable. An inner cover is fixedly connected to the inner side of the processing cylinder. A filter screen is fixedly connected to the bottom of the inner cover. A sponge ring is fixedly connected to the outer side of the filter screen. A power assembly is provided at the bottom of the front side of the processing cylinder.

[0007] The above technical solution involves placing sludge into a processing drum, then activating the heating wire to heat the moisture at the bottom of the drum. The high-temperature gas generated by the heating enters the turntable through the air inlet hood, heating the turntable and thus drying the sludge. Simultaneously, the turntable begins to rotate, and the protrusions on it enhance the contact and mixing effect with the sludge, making the drying process more efficient. After passing through the filter screen, the moisture in the sludge is intercepted by the sponge ring, and then the moisture is discharged to the bottom of the processing drum. This design can both utilize the moisture in the sludge to dry it and extend the service life of the turntable.

A cross blade is fixedly connected to the top of the rotating column through the filter cover. An arc-shaped blade is fixedly connected to the top of the inner side of the filter cover. A top cover is provided on the top of the filter cover.

[0010] Through the above technical solution, the rotation of the turntable drives the rotation of the rotating column, which in turn causes the cross blades to rotate, adding sludge into the filter cover. As the sludge rotates with the cross blades, it intersects with the cross blades and the arc blades, thus cutting the sludge into long strips and pushing the cut sludge through the filter cover into the device. This method can cut the sludge into pieces during feeding, which not only prevents the sludge from clumping, but also increases the contact area between the sludge and the air and reduces the volume, thereby improving the drying effect.

[0011] As a further description of the above technical solution:

[0012] The power assembly includes a motor, the output end of which passes through the processing cylinder and is fixedly connected to a rotating rod. A bevel gear is fixedly connected to the outer front side of the rotating rod, and a bevel gear ring is fixedly connected to the bottom of the turntable. The bevel gear ring meshes with the bevel gear.

[0013] Through the above technical solution, the starter motor can drive the rotating rod and the bevel gear to rotate, thereby driving the bevel gear ring to drive the turntable to rotate.

[0014] As a further description of the above technical solution:

[0015] The rear side of the rotating rod passes through the processing cylinder and is fixedly connected to an indicator needle, and a scale bar is fixedly connected to the top rear side of the processing cylinder.

[0016] With the above technical solution, when the rotating rod rotates, it will drive the indicator needle to rotate. By observing the scale bar indicated by the indicator needle, the current rotation speed of the turntable can be determined.

[0017] As a further description of the above technical solution:

[0018] The drying mechanism also includes a chute, and a chute is provided at the bottom right side of the processing cylinder, with a sliding plate slidably connected to the inner side of the chute.

[0019] Using the above technical solution, the bottom of the processing cylinder can be opened by moving the slide along the groove for cleaning and maintenance.

[0021] The feeding mechanism also includes a movable door, which is located inside the top cover. A hinge is fixedly connected to the top front side of the movable door, and the movable door is rotatably connected to the top cover through the hinge.

[0022] The above technical solution allows the hinge to open and close the movable door, facilitating the addition of sludge into the device.

[0023] As a further description of the above technical solution:

[0024] The feeding mechanism also includes a positioning frame, which is fixedly connected to the inside of the movable door, and an observation window is fixedly connected to the inside of the positioning frame.

[0025] The above technical solution allows for intuitive observation of the device's operation through the observation window, enabling timely adjustments and operation.

[0026] As a further description of the above technical solution:

[0027] The feeding mechanism also includes positioning blocks, and multiple positioning blocks are respectively fixedly connected to the outer periphery of the filter cover and the top cover. Screws are threadedly connected to the inner side of the positioning blocks, and the multiple positioning blocks are threadedly connected to each other through the screws.

The sludge moisture passes through the filter screen, is intercepted by the sponge ring, and is discharged to the bottom of the processing cylinder. This method can utilize the moisture in the sludge to dry the sludge and also improve the service life of the turntable, thereby improving the reliability of the device.

[0031] 2. In this utility model, the rotating column is driven to rotate by the rotation of the turntable, which in turn causes the cross blade to rotate. Sludge is added into the filter cover. As the cross blade rotates, it intersects with the cross blade and the arc blade, which can cut the sludge into long strips and push the cut sludge through the filter cover and into the device. It can cut the sludge into pieces during feeding, which can prevent the sludge from clumping, increase the contact area with air and reduce the volume, thereby improving the drying effect and improving the convenience of the device.

An air inlet hood 202 is connected to the bottom center of the turntable 201, facilitating the entry of evaporated steam into the turntable 201. A heating wire 203 is fixedly connected to the bottom inner side of the processing cylinder 1; activating the heating wire 203 heats the water at the bottom inner side of the processing cylinder 1 to generate steam. Multiple protrusions 204 are fixedly connected to the top of the turntable 201, and the rotation of the turntable 201 facilitates mixing... The sludge is mixed, and the protrusions 204 on it can increase the heating area of ​​the turntable 201 and reduce wear by increasing the strength. An inner cover 207 is fixedly connected to the inner side of the processing cylinder 1. A filter screen 205 is fixedly connected to the bottom of the inner cover 207.

[0042] Specifically, the sludge is stored in the processing cylinder 1, and then the heating wire 203 is activated to heat the water at the bottom of the inner side of the processing cylinder 1. The high-temperature gas generated by evaporation enters the turntable 201 through the air inlet hood 202 to heat the turntable 201 to dry the sludge. When the turntable 201 rotates, the protrusions 204 on it can enhance the contact and mixing effect with the sludge. The water in the sludge is filtered out by the filter screen 205 and after being intercepted by the sponge ring 206, it is discharged to the bottom of the processing cylinder 1.

[0043] Reference Figure 1 , Figure 2 and Figure 5The feeding mechanism 3 includes a rotating column 301, which is fixedly connected to the top center of the turntable 201. When the turntable 201 rotates, it will also drive the rotating column 301 to rotate. A filter cover 302 is fixedly connected to the top of the processing cylinder 1. A cross blade 303 is fixedly connected to the top of the rotating column 301 through the filter cover 302. An arc blade 304 is fixedly connected to the top of the inner side of the filter cover 302.

[0044] Specifically, when the turntable 201 starts to rotate, it will synchronously drive the rotating column 301 to rotate as well. When the rotating column 301 rotates, it will also cause the cross blade 303 to rotate. At this time, the sludge is added into the filter cover 302. As the cross blade 303 rotates, it intersects with the cross blade 303 and the arc blade 304, which can cut the sludge into long strips and push the cut sludge through the filter cover 302 into the device.

An indicator needle passes through the rear side of the rotating rod 209 and is fixedly connected to it. 213. A scale bar 214 is fixedly connected to the top rear side of the processing cylinder 1. When the rotating rod 209 rotates, the indicator needle 213 on it will also rotate.

The drying mechanism 2 also includes a slide groove 215. A slide groove 215 is opened at the bottom right side of the processing cylinder 1. A slide plate 211 is slidably connected to the inner side of the slide groove 215. Opening and closing the slide plate 211 along the slide groove 215 can facilitate the cleaning and maintenance of the inside of the processing cylinder 1.

[0046] Specifically, starting the motor 208 drives the rotating rod 209 to rotate. As the rotating rod 209 rotates, it also drives the bevel gear 212 to rotate. This rotation drives the bevel gear ring 210 and the turntable 201 meshing with it to rotate, thus facilitating the rotation of the turntable 201. The rotation of the rotating rod 209 also drives the indicator needle 213 to rotate. By observing the position of the scale bar 214 indicated by the indicator needle 213, the current rotation speed and angle of the turntable 201 can be observed. The slide plate 211 can slide through the inner side of the slide groove 215 to open the bottom of the processing cylinder 1 for cleaning or adding water to the inside.

The connection between the screws 311 and the positioning blocks 310 allows for disassembly or fixing of the filter cover 302 and the top cover 305.

[0048] Specifically, the hinge 307 allows the movable door 306 to be opened and closed, facilitating the addition of sludge to the filter cover 302. Meanwhile, the observation window 309 inside the positioning frame 308 allows for easy observation of the device's operation. The screws 311 connect the positioning blocks 310 on the upper and lower sides, thereby connecting the top cover 305 and the filter cover 302. This also facilitates quick disassembly and cleaning.

[0049] Working principle: Before using the device, sludge is first placed in the processing cylinder 1. Then, the heating wire 203 is activated to heat the moisture at the bottom of the inner side of the processing cylinder 1. The evaporated high-temperature gas enters the turntable 201 through the air inlet hood 202. The sludge is dried by heating the turntable 201. At the same time, the rotation of the turntable 201 can also improve the contact and mixing effect with the sludge during rotation through the protrusions 204 on it. Furthermore, the moisture in the sludge will pass through the filter screen 205 and be intercepted by the sponge ring 206 before being discharged into the bottom of the processing cylinder 1.

[0050] Furthermore, when the turntable 201 rotates, it can drive the rotating column 301 to rotate. At this time, as the rotating column 301 rotates, the cross blade 303 can rotate. When sludge is added into the filter cover 302, with the rotation of the cross blade 303 and the intersection of the cross blade 303 and the arc blade 304, the sludge can be cut into strips and pushed through the filter cover 302 into the device.
