Description

Technical Field

[0001] This utility model relates to the field of sludge treatment equipment, and in particular to a sludge uniform distribution device. Background Technology

[0002] Sludge treatment primarily targets the lower layer after wastewater sedimentation. Although it is a solid substance, it has a high water content. Therefore, sludge generally needs to be dewatered (pre-dewatered) before treatment, usually by compression to reduce its moisture content. After dewatering, the sludge is generally in the form of cakes or lumps. Although its moisture content is lower than before treatment, further dewatering is still necessary to further reduce its moisture content. Drying is typically used at this stage. Because the pre-dewatered sludge is already in lumps or cakes, the sludge entering the drying unit for further dewatering is often unevenly distributed, resulting in poor drying efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a sludge uniform distribution device.

[0004] This utility model is achieved using the following technical solution: a sludge uniform distribution device, comprising a shell, a sludge inlet at one end of the shell, a sludge outlet at the other end of the shell, a uniform distribution component inside the shell, the sludge inlet being connected to a feeding device, the feeding device conveying sludge to the uniform distribution component through the sludge inlet, and the sludge outlet being connected to a drying device, the uniform distribution component conveying sludge to the drying device through the sludge outlet;

[0005] The uniform distribution component includes an upper compaction section and a lower support section. The sludge is placed on the lower support section, and the upper compaction section and the lower support section are close to each other and move relative to each other.

[0006] The upper rolling part includes a pushing member and a rolling member. The pushing member is fixed on the housing, and the rolling member is connected to the pushing member and is pushed by the pushing member toward or away from the lower support part.

[0007] The rolling element includes a rolling plate, and the pushing element includes a winch. One end of the rolling plate is rotatably connected to the inner wall of the housing. The winch is fixed to the inner wall of the housing. The rolling plate and the winch roller are connected by a cable. When the winch releases the cable, the rolling plate flips toward the lower support.

[0008] The end face of the rolling plate opposite to the lower support is provided with a plurality of protrusions, which are arranged in a grid pattern.

[0009] The lower support includes a support frame with a fixed grid plate on the upper part of the support frame. When the compactor moves toward the lower support, the compactor contacts the grid plate. The sludge outlet is located below the grid plate, and the grid plate is positioned below the sludge inlet.

[0010] The support frame is provided with a mounting ring for supporting the support frame. The bottom of the mounting ring is provided with a motor. The support frame is placed on the mounting ring and is driven to rotate by the motor.

[0011] The bottom of the support frame is provided with a toothed ring, and the side of the mounting ring that contacts the support frame is provided with a ball bearing, the outer edge of which contacts the end face of the support frame.

[0012] Compared to existing technologies, this invention, when lumps of sludge fall onto the grid plate from the sludge inlet, moves the pressing plate towards the grid plate and eventually presses it onto the sludge. As the pressing plate presses down and the supporting plate rotates, the sludge is gradually broken down by the grid plate, forming spherical shapes of similar size, which finally fall into the drying device through the sludge outlet. Because the shape and size of the sludge falling into the drying device are more uniform, the drying effect is better. Attached Figure Description

[0016] 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.

[0017] Reference Figure 1-2A sludge distribution device includes a housing 1, with a sludge inlet 11 at one end, connected to a feeding device 3. The feeding device 3 conveys sludge to a distribution component 2 through the sludge inlet 11. A sludge outlet 12 is connected to a drying device, with the distribution component 2 conveying sludge to the drying device through the sludge outlet 12. In this embodiment, the feeding device 3 can be an auger. After the sludge is fed through the feeding device 3, it falls into the housing 1 through the sludge inlet 11. The distribution component 2, located in the housing 1, crushes the sludge conveyed by the feeding device 3, allowing it to fall into the drying device through the sludge outlet 12 at the other end of the housing 1. Because the sludge is crushed and falls evenly through the distribution component 2, it is evenly distributed in the drying device, resulting in a better drying effect. In this embodiment, the drying device can be a commonly used hot air drying device, where the housing 1 of the drying device is filled with hot air, and the granular sludge is dried by the hot air after falling into the housing 1.

[0018] In this embodiment, the uniform distribution component 2 includes an upper crushing section 21 and a lower supporting section 22. The sludge is placed on the lower supporting section 22, and the upper crushing section 21 and the lower supporting section 22 are close to each other and move relative to each other. As the upper crushing section 21 presses down and the lower supporting section 22 rotates, the sludge is gradually divided by the lower supporting section 22 into spherical particles of similar size, and finally falls into the drying device through the sludge outlet 12. Because the shape and size of the sludge falling into the drying device are relatively uniform, the drying effect is better.

[0019] In this embodiment, the upper compaction section 21 includes a pushing member and a compaction member. The pushing member is fixed inside the housing 1 and can be a winch 212. The compaction member includes a compaction plate 211. The compaction plate 211 can be a smooth plate, or it can have several protrusions on the end face of the compaction plate 211 opposite to the lower support section 22, arranged in a grid pattern. The winch 212 and the compaction plate 211 can be connected by a cable 213. One end of the cable 213 can be fixed to the compaction plate 211, and the end of the compaction plate 211 can be hinged to the inner wall of the housing 1 so that the compaction plate 211 can move closer to or further away from the lower support section 22. As the winch 212 rotates, the cable 213 is released, and the compaction plate 211 flips downward toward the lower support section 22 around the hinge point and presses onto the sludge.

[0020] The lower support section 22 includes a support frame 221 and an upper fixed grid plate 222 on the support frame 221. When the compactor moves downward to the lower support section 22, the compactor contacts the grid plate 222. The sludge outlet 12 is located below the grid plate 222, and the grid plate 222 is positioned below the sludge inlet 11. When clumps of sludge fall from the sludge inlet 11 onto the grid plate 222, the compactor plate 211 moves toward the grid plate 222 and finally presses onto the sludge. At this time, as the compactor plate 211 presses down and the support plate rotates, the sludge is gradually divided by the grid plate 222, forming spherical shapes of similar size, and finally falls into the drying device through the sludge outlet 12. Because the shape and size of the sludge falling into the drying device are relatively uniform, the drying effect is better.

[0021] The housing 1 is provided with a mounting ring 223 for supporting the support frame 221. A motor is located at the bottom of the mounting ring 223. The support frame 221 is placed on the mounting ring 223 and driven to rotate by the motor. A toothed ring 224 is located at the bottom of the support frame 221. A ball bearing is located on the side of the mounting ring 223 that contacts the support frame 221, with the outer edge of the ball bearing contacting the end face of the support frame 221. A mesh plate 222 is mounted on the support frame 221 and can be fixed to the support frame 221 with bolts for easy replacement. The appropriate mesh size is selected based on the actual application. The ball bearing between the mounting ring 223 and the support frame 221 reduces friction, making the rotation of the support frame 221 smoother.

[0022] Compared to existing technologies, in this invention, when clumps of sludge fall onto the grid plate 222 through the sludge inlet 11, the pressing plate 211 moves towards the grid plate 222 and eventually presses down on the sludge. As the pressing plate 211 presses down and the supporting plate rotates, the sludge is gradually broken up by the grid plate 222, forming spherical shapes of similar size, which finally fall into the drying device through the sludge outlet 12. Because the shape and size of the sludge falling into the drying device are more uniform, the drying effect is better.

[0023] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. 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.
