Description

Technical Field

[0001] This utility model relates to the technical field of mud treatment devices, specifically to an inclined plate separator for mud treatment. Background Technology

[0002] The generation of mud is enormous in numerous industrial sectors, including construction, mining, and oil drilling. Mud not only contains a large number of solid particles but may also contain harmful substances. Direct discharge without effective treatment can cause serious environmental pollution, making mud treatment a crucial aspect that these industries must prioritize. Mud-water separation, a key step in mud treatment, aims to separate solid particles from water in the mud, enabling the recycling of water resources and the proper disposal of solid waste.

[0003] Currently, inclined plate separators are widely used in sludge-water separation processes in mud treatment due to their efficient sedimentation and separation characteristics. However, traditional inclined plate separators for mud treatment have several drawbacks. On the one hand, the surfaces of the inclined plates in traditional inclined plate separators are relatively smooth, and the water flow between the plates is in a laminar state, making it difficult for solid particles to collide and aggregate effectively, resulting in low sedimentation efficiency and unsatisfactory separation effects. On the other hand, the sludge entering traditional inclined plate separators often directly impacts the inclined plate components, which not only damages the components and shortens their service life but also causes uneven distribution of the sludge on the components, further affecting the separation efficiency. Utility Model Content

[0004] (I) Technical Issues

[0005] This invention provides an inclined plate separator for mud treatment, which solves the problems of low sedimentation efficiency, easy damage to the inclined plate, and uneven mud distribution in traditional equipment.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: an inclined plate separator for mud treatment, including a separation box, a mud inlet on one side of the top of the separation box and a clean water outlet on the other side, a plurality of inclined plate assemblies are inclinedly arranged inside the separation box, and a U-shaped sedimentation channel is formed between adjacent inclined plate assemblies. The front and rear sides of the inclined plate assemblies are fixedly connected by a sealing plate. A plurality of protrusions are provided on the inner surface of the U-shaped sedimentation channel. The protrusions are frustum-shaped and their tips are pointing upwards. A buffer plate is provided inside the separation box below the mud inlet. A plurality of guide grooves are fixedly provided on the upper surface of the buffer plate to evenly distribute the sewage into the inclined plate assembly.

[0008] Furthermore, the bottom of the separation box is provided with a sludge collection hopper, the sludge collection hopper is connected to a sludge discharge pipe, and a sludge pump is connected to the sludge discharge pipe.

[0009] Furthermore, the guide grooves are radially distributed on the upper surface of the buffer plate.

[0010] Furthermore, the buffer plate is inclined and its lower end is close to the top of the inclined plate assembly.

[0011] Furthermore, the cross-section of the inclined plate assembly has an alternating concave-convex corrugated shape.

[0012] (III) Technical Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. Accelerate sedimentation and improve separation effect: The U-shaped sedimentation channel of the inclined plate assembly has a frustum-shaped protrusion with the tip pointing upward, which can effectively disrupt the laminar flow of water, making solid particles more likely to collide and agglomerate, greatly accelerating the sedimentation process. Compared with traditional smooth inclined plate separators, the sedimentation efficiency is significantly improved.

[0015] 2. Protect the inclined plate assembly and extend the equipment life: A buffer plate is installed below the mud inlet inside the separation box to buffer the mud entering the separation box, avoid the mud directly impacting the inclined plate assembly at high speed, and reduce the wear and impact force on the inclined plate assembly.

[0016] 3. Uniform flow distribution and optimized processing flow: The upper surface of the buffer plate is fixed with radially distributed guide channels to evenly distribute the mud into the inclined plate assembly, ensuring that the mud is evenly distributed on the inclined plate assembly and that each U-shaped sedimentation channel can play its full role.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Combined with appendix Figure 1 To be continued Figure 5 An inclined plate separator for mud treatment includes a separation box 1. The top of one side of the separation box 1 is provided with a mud inlet 5 and the other side is provided with a clean water outlet 6. Several inclined plate assemblies 3 are inclinedly arranged inside the separation box 1. A U-shaped sedimentation channel 4 is formed between adjacent inclined plate assemblies 3. The front and rear sides of the inclined plate assemblies 3 are fixedly connected by sealing plates 2. Several protrusions 7 are provided on the inner surface of the U-shaped sedimentation channel 4. The protrusions 7 are frustum-shaped and their tips are pointing upwards. A buffer plate 11 is provided inside the separation box 1 below the mud inlet 5. Several guide grooves 12 are fixedly provided on the upper surface of the buffer plate 11 to evenly distribute the sewage into the inclined plate assemblies 3.

[0027] The bottom of the separation box 1 is provided with a sludge collection hopper 8, which is connected to a sludge discharge pipe 9, and a sludge pump 10 is connected to the sludge discharge pipe 9. The guide channels 12 are radially distributed on the upper surface of the buffer plate 11. The buffer plate 11 is inclined, with its lower end close to the top of the inclined plate assembly 3. The cross-section of the inclined plate assembly 3 is a corrugated shape with alternating concave and convex features.

[0028] The working principle of this utility model is as follows: the U-shaped sedimentation channel 4 formed by the inclined plate assembly 3 increases the sedimentation area, and the sedimentation of solid particles in the sludge is accelerated based on the shallow sedimentation theory. The frustum-shaped protrusions 7 disrupt the laminar flow state of the water, promote particle collision and agglomeration, the buffer plate 11 and the guide channel 12 uniformly disperse the sludge and reduce its flow velocity, and the sludge collection hopper 8, sludge discharge pipe 9 and sludge pump 10 realize the discharge of settled sludge.

[0029] The working process of this utility model is as follows:

[0030] 1. Mud entry: The mud to be treated enters from the mud inlet 5 at the top of one side of the separation tank 1.

[0031] 2. Buffering and Diversion: The incoming mud first impacts the inclined buffer plate 11, which buffers the mud and slows down its flow rate. The radially distributed guide grooves 12 on the upper surface of the buffer plate 11 evenly divert the mud, so that its lower end is close to the top of the inclined plate assembly 3, allowing the mud to flow evenly towards the inclined plate assembly 3.

[0032] 3. Sedimentation and Separation: The slurry flows into the U-shaped sedimentation channel 4 formed between adjacent inclined plate components 3. The cross-section of the inclined plate components 3 is corrugated with alternating concave and convex shapes, increasing the sedimentation area. The frustum-shaped protrusions 7 on the inner surface of the U-shaped sedimentation channel 4 with their tips pointing upwards disrupt the laminar flow of the water, promoting the collision and aggregation of solid particles and accelerating sedimentation. Under the action of gravity, the solid particles settle to the bottom of the U-shaped sedimentation channel 4.

[0033] 4. Clear water discharge: The clear water after sedimentation and separation is discharged from the clear water outlet 6, which is connected to an external water pump.

[0034] 5. Sludge discharge: The sludge settled at the bottom of the U-shaped sedimentation channel 4 slides down to the sludge collection hopper 8 at the bottom of the separation box 1. Through the sludge discharge pipe 9 connected to the sludge collection hopper 8, the sludge is discharged from the separation box 1 by the sludge pump 10 on the sludge discharge pipe 9, thus completing the entire sludge treatment process.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
