Description

Technical Field

[0001] This utility model relates to the field of clarifier technology, and in particular to a clarifier sludge discharge sleeve that is easy to disassemble. Background Technology

[0002] Clarifiers are key equipment in the papermaking industry for treating liquids such as green liquor and white liquor. They remove suspended solids (such as green mud and white mud) through gravity settling and flocculation. During operation, the liquid (such as green liquor or white liquor) enters the clarifier and mixes thoroughly with the flocculant in the mixing reaction chamber, forming large flocs. These flocs gradually sink in the settling separation zone under gravity, forming a mud layer, while the clear water is discharged through an overflow weir or pipe, achieving solid-liquid separation. The mud layer accumulates at the bottom of the cone and is periodically discharged through a mud discharge valve and pipe. However, in existing technologies, only one mud discharge pipe is installed, and mud easily clumps and clogs. Therefore, blockages in the mud discharge pipe can render the entire system unusable; and since the mud discharge pipe cannot be replaced, maintenance costs increase. Therefore, a mud discharge pipe structure that can quickly clear and break up clumps while saving time and labor is needed. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a clarifier sludge discharge sleeve that is easy to disassemble, thus solving the problem in the prior art where only one sludge discharge pipe is installed, making it impossible to quickly clean up sludge clumps.

[0004] To achieve the above objectives, this utility model provides a clarifier sludge discharge sleeve that is easy to disassemble, including an outer sleeve and an inner sleeve inside the outer sleeve. The outer sleeve and the inner sleeve form a sleeve assembly, and the sleeve assembly is connected to the sludge discharge well.

[0005] As a preferred technical solution, one end of the inner sleeve extends out of the outer sleeve.

[0006] As a preferred technical solution, one end of the outer sleeve is connected to the side wall of the sludge discharge well, and the other end of the outer sleeve is provided with a first connecting edge; the outer wall of the inner sleeve is provided with a second connecting edge, and the first connecting edge and the second connecting edge are detachably connected together.

[0007] As a preferred technical solution, a first sealing gasket is provided between the first connecting edge and the second connecting edge.

[0008] As a preferred technical solution, the length of the inner sleeve inserted into the outer sleeve is the same as the length from the second connecting edge to the mud discharge well.

[0009] As a preferred technical solution, a hot water inlet is provided at the position where the inner sleeve protrudes from the outer sleeve.

[0010] As a preferred technical solution, the inner sleeve is connected to a connecting pipe, and the connecting pipe is provided with a drain port; The drain ports in the two sets of sleeve assemblies are arranged opposite each other, both located on the sidewall of the corresponding connecting pipe and away from each other.

[0011] As a preferred technical solution, the connecting pipe is connected to the pump body.

[0012] As a preferred technical solution, the casing assembly is symmetrically arranged in two sets and is connected to the mud discharge well in a mirror-symmetrical manner.

[0013] This utility model provides a clarifier sludge discharge sleeve that is easy to disassemble. By setting the sleeve assembly, it can be replaced according to the sludge clumping in the inner sleeve, avoiding the problem of pipe blockage caused by only having one sludge discharge pipe. Moreover, the replaced inner sleeve can be reinstalled into the outer sleeve after cleaning the sludge, which has a high reuse rate, is convenient for disassembly and maintenance, saves time and effort, and improves efficiency.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] Example 1: See Figure 1Figure 3 shows a clarifier sludge discharge sleeve that is easy to disassemble, comprising a sleeve assembly 5, which connects to a sludge discharge well 6. Preferably, two sets of sleeve assemblies 5 are symmetrically arranged and mirror-symmetrically connected to the sludge discharge well 6.

[0017] For details, see Figure 4 The sludge discharge sleeve 5 includes an outer sleeve 51 and an inner sleeve 52. The outer sleeve 51 is sleeved on the outside of the inner sleeve 52, and one end of the inner sleeve 52 protrudes out of the outer sleeve 51.

[0018] See Figure 4 and Figure 5 One end of the outer sleeve 51 is connected to the side wall of the sludge discharge well 6, and the other end of the outer sleeve 51 is provided with a first connecting edge 511.

[0019] The inner sleeve 52 has a second connecting edge 522 on its outer wall. The length of the inner sleeve 52 inserted into the outer sleeve 51 is the same as the length from the second connecting edge 522 to the mud discharge well 6.

[0020] The first connecting edge 511 and the second connecting edge 522 are detachably connected together. In order to ensure the sealing between the first connecting edge 511 and the second connecting edge 522, a first sealing gasket 54 is provided between them.

[0021] See Figure 4 The inner sleeve 52 is connected to a connecting pipe 53, which is connected to a pump body, allowing the discharged mud to be transported over long distances or at high distances (10m). Alternatively, the connecting pipe 53 may not be connected to the pump body, allowing the mud to be discharged directly.

[0022] Furthermore, the inner sleeve 52 and the connecting pipe 53 are connected by a flange. To increase their sealing performance, a sealing ring can be installed between the flanges.

[0023] See Figure 6 A hot water inlet 521 is provided at the position where the inner sleeve 52 protrudes from the outer sleeve 51. When mud clumps inside the inner sleeve 52 or the inner sleeve 52 is blocked, hot water is injected through the hot water inlet 521 to quickly soften and remove the clumps.

[0024] The hot water inlet 521 is located above the inner sleeve 52.

[0025] The connecting pipe 53 is provided with a drain port 531. The drain ports 531 in the two sets of sleeve assemblies 5 are arranged opposite each other, and are located on the side wall of the corresponding connecting pipe 53 and away from each other.

[0026] See Figure 1 and Figure 3The sludge discharge well 6 is located at the bottom of the clarifier 1. A stirring shaft 2 is installed inside the clarifier 1. A rake body 3 and a stirring frame 4 are connected to the stirring shaft 2. The rake body 3 is located inside the stirring chamber of the clarifier 1, and the stirring frame 4 is located inside the sludge discharge well 6. The stirring frame 4 has a grid structure. The stirring shaft 2 rotates under the drive of a motor, which in turn drives the rake body 3 and the stirring frame 4 to rotate. The sludge is pushed into the sludge discharge well 6 by the rotation of the rake body 3, and then squeezed by the rotation of the stirring frame 4 before being discharged from the clarifier 1 through the casing assembly 5.

[0027] This utility model provides a clarifier sludge discharge sleeve that is easy to disassemble. By setting the sleeve assembly, it can be replaced according to the sludge clumping in the inner sleeve, avoiding the problem of pipe blockage caused by only having one sludge discharge pipe. Moreover, the replaced inner sleeve can be reinstalled into the outer sleeve after cleaning the sludge, which has a high reuse rate, is convenient for disassembly and maintenance, saves time and effort, and improves efficiency.

[0028] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
