Abstract
Description
Technical Field
[0001] The present application relates to the field of environmental protection technology, and in particular to a sludge concentration device. Background Art
[0002] Sludge thickening in sludge treatment is an effective method to reduce the moisture content of sludge and reduce the volume of sludge. Sludge thickening mainly reduces the interstitial water in the sludge. The sludge after thickening is approximately paste-like.
[0003] Mineral sludge water and coal sludge water contain a large amount of sludge, which must be treated in order to meet discharge standards or be recycled and reused. In the water treatment process, concentration treatment must be carried out before the dehydration process. The concentration treatment adopts a sludge concentration device or a concentration tank. The top of the tank body of the traditional sludge concentration device is connected with a sludge water inlet pipe and a sludge outlet pipe at the bottom. After the sludge water enters the tank body through the water inlet pipe, it is allowed to stand in the tank body for 12 to 48 hours. The sludge settles to the bottom of the tank body and is discharged through the sludge outlet pipe. The supernatant is discharged through the outlet pipe at the top of the tank body. The disadvantage of this sludge concentration device is that the sludge water is directly flushed into the tank, causing an impact on the existing sludge in the tank, and a longer standing time is required. Summary of the Invention
[0004] The embodiment of the present application provides a sludge thickening device to solve the problem in the related art that the muddy water in the existing sludge thickening device will directly rush into the tank after entering the tank, causing impact on the existing sludge in the tank and requiring a long standing time.
[0005] The present invention provides a sludge concentrating device, comprising:
[0006] The tank body comprises a shell, a feed port opened on the side wall of the shell, and a mud discharge port opened at the bottom of the shell;
[0007] The diversion and mud distribution mechanism is arranged in the shell and connected with the feed port. The diversion and mud distribution mechanism includes a diversion pipe connected with the feed port. The end of the diversion pipe away from the feed port is provided with a diversion port structure that can discharge the mud-water mixture toward the side wall of the shell.
[0008] In some embodiments, the guide port structure includes a trumpet-shaped discharge port and a guide plate spaced apart from the discharge port on a side away from the guide pipe and inclined toward the side wall of the housing;
[0009] A connecting rib is provided between the guide plate and the discharge port.
[0010] In some embodiments, a plurality of the connecting ribs are arranged in a ring-like manner along the axis of the discharge port, so that a guide port is formed between every two connecting ribs.
[0011] In some embodiments, the guide plate is in a prism shape, and includes a transverse plate and a plurality of inclined plates arranged around the transverse plate, and the transverse plate is arranged opposite to the discharge port in a spaced relationship;
[0012] The inclined plate is connected to the connecting rib, and the inclined plate is inclined toward a side away from the discharge port.
[0013] In some embodiments, a connecting port is provided on the flow guide tube, and a feed pipe is connected between the feed port and the connecting port.
[0014] In some embodiments, the housing is provided with an overflow port and a drain port in sequence from top to bottom;
[0015] The overflow port and the drain port both transport the supernatant in the shell to the water pool.
[0016] In some embodiments, there are multiple drain outlets arranged in sequence from top to bottom along the side wall of the shell.
[0017] In some embodiments, the feed port is disposed between the drain port and the overflow port.
[0018] In some embodiments, one side of the mud discharge port is connected to a mud discharge pipe, and the other side is provided with a drain pipe connected to the water pool;
[0019] The drain pipe is provided with a valve.
[0020] In some embodiments, a heat conducting pipe is provided at one end of the shell near the mud discharge port.
[0021] The beneficial effects of the technical solution provided by this application include:
[0022] The mud-water mixture enters the guide pipe in the guide mud distribution mechanism through the feed port, and then flows to the guide port structure along the pipeline path of the guide pipe. The guide port structure guides the mud-water mixture toward the side wall of the shell and discharges it into the tank body. The guide port structure is tilted to discharge the mud-water mixture into the tank body, so as to avoid the mud-water mixture that falls directly from causing direct impact on the already accumulated sludge. The deposited sludge will be splashed around by the impact and mixed with the separated supernatant again, causing the supernatant to be polluted, resulting in reduced mud-water separation efficiency and effect. In order to avoid the vertically falling sludge from continuing to accumulate directly below the guide pipe, causing the sludge below to continue to accumulate, but the tank space on both sides is not effectively used, when the sludge accumulates too high, it will block the guide pipe and will also be mixed into the supernatant. The guide port structure is tilted toward the side wall of the shell so that the sludge can use the bottom of the bucket-shaped shell to flow from the outside to the inside and be evenly accumulated, so that the sludge can be evenly distributed at the bottom of the shell, avoiding continuous accumulation in a certain place.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0028] The embodiment of the present application provides a sludge thickening device, which can solve the problem of existing sludge thickening devices that muddy water will directly rush into the tank after entering the tank, causing impact on the existing sludge in the tank and requiring a long standing time.
[0029] See also Figure 1-2 As shown, the embodiment of the present application provides a sludge concentrating device, comprising:
[0030] The tank body includes a shell 1, a feed port 11 opened on the side wall of the shell 1 and a mud discharge port 12 opened at the bottom of the shell 1. The bottom of the shell 1 is bucket-shaped for collecting sludge, so that the sludge can be collected at the mud discharge port 12 and discharged through the mud discharge port 12.
[0031] The diversion and mud distribution mechanism is arranged in the shell body 1 and is connected with the feed port 11. The diversion and mud distribution mechanism includes a diversion pipe 2 connected with the feed port 11. The end of the diversion pipe 2 away from the feed port 11 is provided with a diversion port structure 21 that can discharge the mud-water mixture toward the side wall of the shell body 1. The feed port 11 and the diversion pipe 2 are connected and connected with a connecting pipe.
[0032] The mud-water mixture enters the guide pipe 2 in the guide mud distribution mechanism through the feed port 11, and then flows to the guide port structure 21 along the pipeline path of the guide pipe 2. The guide port structure 21 guides the mud-water mixture toward the side wall of the shell 1 and discharges it into the tank body. The guide port structure 21 is tilted to discharge the mud-water mixture into the tank body, so as to avoid the mud-water mixture falling directly from directly impacting the accumulated sludge. The deposited sludge will be splashed around by the impact and mixed with the separated supernatant again, so that the upper The clear liquid is polluted, resulting in a decrease in the efficiency and effect of mud-water separation, and in order to prevent the vertically falling sludge from continuing to accumulate directly below the guide pipe 2, causing the sludge below to continue to accumulate, but the tank space on both sides is not effectively used. When the sludge accumulates too high, it will block the guide pipe 2 and will also be mixed into the supernatant. By tilting the guide port structure 21 toward the side wall of the shell 1, the sludge can flow from the outside to the inside through the bottom of the bucket-shaped shell 1 and be evenly accumulated, so that the sludge can be evenly distributed at the bottom of the shell 1, avoiding continuous accumulation in a certain place.
[0033] In some optional embodiments, see Figure 1-2 As shown, in the sludge thickening device, the guide port structure 21 includes a trumpet-shaped discharge port 22 and a guide plate 23 arranged in space on the side of the discharge port 22 away from the guide pipe 2 and inclined toward the side wall of the shell 1, and a connecting rib 24 is provided between the guide plate 23 and the discharge port 22.
[0034] In this embodiment, a plurality of connecting ribs 24 are arranged in a ring-like manner along the axis of the discharge port 22 , so that a guide port 25 is formed between every two connecting ribs 24 .
[0035] The trumpet-shaped discharge port 22 can make the discharge of the guide pipe 2 smoother, and a guide channel is formed between the guide plate 23 arranged opposite to each other in the air, so that the mud-water mixture is discharged toward the side wall of the shell 1. The connecting rib 24 fixes the guide plate 23 and the discharge port 22 to fix the guide plate 23.
[0036] There are several connecting ribs 24 arranged at intervals around the axis of the guide plate 23 and the discharge port 22, so that a guide channel is formed between every two adjacent connecting ribs 24 to discharge the mud-water mixture into the tank body, wherein the connecting ribs 24 can be rod-shaped or plate-shaped.
[0037] In some optional embodiments, see Figure 1-2As shown, in the sludge thickening device, the guide plate 23 is in the shape of a prism, and the guide plate 23 includes a horizontal plate and a plurality of inclined plates arranged on the side of the horizontal plate. When the mud-water mixture falls on the horizontal plate, the mud-water mixture is discharged toward the side wall of the shell 1 through the guidance of the plurality of inclined plates. The horizontal plate on the side of the guide plate 23 is arranged opposite to the discharge port 22 in the air, and the inclined plate is connected to the connecting rib 24, and the inclined plate is inclined toward the side away from the discharge port 22.
[0038] The guide plate 23 is in the shape of a prism. When the mud-water mixture enters the guide pipe 2, the mud-water mixture will first impact the horizontal plate, and the impact of the mud-water mixture will be reduced by the horizontal plate. Then, the mud-water mixture will be guided by the inclination of the inclined plate, flowing out from the guide port 25 and toward the side wall of the shell 1.
[0039] In some optional embodiments, see Figure 1-2 As shown, in the sludge concentration device, a connection port 26 is opened on the guide pipe 2, and a feed pipe 3 is connected between the feed port 11 and the connection port 26, so that the mud-water mixture can enter the guide pipe 2 through the feed pipe 3.
[0040] In some optional embodiments, see Figure 1-2 As shown, in the sludge concentrating device, the shell 1 is provided with an overflow port 4 and a drain port 5 in sequence from top to bottom. Both the overflow port 4 and the drain port 5 allow the supernatant in the shell 1 to be transported to the water pool.
[0041] In this embodiment, there are multiple drain ports 5 arranged in sequence from top to bottom along the side wall of the shell 1. Opening the drain ports 5 at different heights allows the supernatant to be discharged at different heights.
[0042] In this embodiment, the feed port 11 is disposed between the drain port 5 and the overflow port 4 .
[0043] The overflow port 4 is located above the drain port 5. When the supernatant in the housing 1 exceeds the drain port 5, the supernatant can be discharged through the overflow port 4 to prevent the supernatant in the tank from overflowing the tank. The tank is filled with nitrogen to prevent the gas in the sludge water from escaping. This not only protects the environment, but also prevents oxidation inside the sludge tank. This improves the sludge settling effect and ensures sufficient pressure during the mud-water separation process.
[0044] A delivery pipe connected to the pool is provided on one side of the tank body on the ground, and connecting pipes are connected between the overflow port 4 and the drain port 5 to the delivery pipe so that the supernatant flows into the delivery pipe and finally flows into the pool.
[0045] In some optional embodiments, see Figure 1-2As shown, in the sludge concentrating device, one side of the sludge discharge port 12 is connected to a sludge discharge pipe 7, and the other side is provided with a drain pipe 8 connected to the water pool. A valve 81 is provided on the drain pipe 8, and a switch valve can also be provided on the sludge discharge pipe 7.
[0046] A mud discharge pipe 7 is connected on the ground and on one side of the mud discharge port 12. When sludge needs to be discharged, it is discharged from the mud discharge pipe 7. A drain pipe 8 is connected on the other side of the mud discharge port 12. The drain pipe 8 is connected and connected to the conveying pipe on the ground. A valve 81 is provided on the drain pipe 8. When discharging mud, the valve 81 is closed to prevent the sludge from entering the drain pipe 8. When the height of the supernatant is lower than the drain port 5 after the sludge is discharged or when the supernatant needs to be discharged from the mud discharge port 12 in other cases, the valve 81 is opened to close the switch valve on the mud discharge pipe 7, so that the supernatant flows into the drain pipe 8 and then flows into the conveying pipe and is transported to the pool.
[0047] In some optional embodiments, see Figure 1-2 As shown, in the sludge concentrating device, a heat conducting pipe 9 is provided at one end of the shell 1 near the sludge discharge port 12. The heat conducting pipe 9 is used for heat preservation in cold weather to ensure the fluidity of the sludge.
[0048] The working principle and process of this application:
[0049] The mud-water mixture enters the guide pipe 2 in the guide mud distribution mechanism through the feed port 11, and then flows to the guide port structure 21 along the pipeline path of the guide pipe 2. The guide port structure 21 guides the mud-water mixture toward the side wall of the shell 1 and discharges it into the tank body. The guide port structure 21 is tilted to discharge the mud-water mixture into the tank body, so as to avoid the mud-water mixture falling directly from directly impacting the accumulated sludge. The deposited sludge will be splashed around by the impact and mixed with the separated supernatant again, so that the upper The clear liquid is polluted, resulting in a decrease in the efficiency and effect of mud-water separation, and in order to prevent the vertically falling sludge from continuing to accumulate directly below the guide pipe 2, causing the sludge below to continue to accumulate, but the tank space on both sides is not effectively used. When the sludge accumulates too high, it will block the guide pipe 2 and will also be mixed into the supernatant. By tilting the guide port structure 21 toward the side wall of the shell 1, the sludge can flow from the outside to the inside through the bottom of the bucket-shaped shell 1 and be evenly accumulated, so that the sludge can be evenly distributed at the bottom of the shell 1, avoiding continuous accumulation in a certain place.
