Description

Technical Field

[0001] This utility model relates to a circulating water sludge removal device, belonging to the field of circulating water treatment technology. Background Technology

[0002] Dust, microorganisms and other impurities in the air enter the circulating pool with the circulating water and gradually settle to form sludge. If not removed in time, they will enter the cooling equipment with the circulating water and adhere to the surface of the cooling equipment. This will not only affect the cooling effect, but may also cause problems such as pipe blockage and accelerated equipment corrosion, seriously affecting the normal operation of the system and production efficiency.

[0003] To address the aforementioned issues, existing technologies often employ settling tanks to remove impurities from circulating water, ensuring consistently good water quality. Over time, sludge accumulates at the bottom of the settling tank. Sludge removal methods primarily include offline and online methods.

[0004] Offline cleaning refers to disconnecting the circulating water, draining the circulating water, and cleaning the bottom of the pool manually or mechanically. Offline cleaning will interrupt the sedimentation process of the circulating water and affect normal production.

[0005] Online sludge removal refers to the mechanical removal of bottom sludge during the normal settling process of circulating water. However, during the mechanical sludge removal process, the sludge that has already settled can be carried back into the water above, resulting in turbid effluent.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This invention addresses the shortcomings of the prior art by providing a circulating water sludge removal device that enables online sludge discharge and prevents settled sludge from being carried back into the water above during the sludge discharge process, thus solving the problem of turbid water caused by the sludge discharge process.

[0008] To solve the above technical problems, the present invention adopts the following technical solution:

[0009] A circulating water sludge removal device includes a settling shell with multiple settling chambers arranged side by side inside. An overflow plate is provided between adjacent settling chambers. A diversion plate is fixedly installed in the middle of the settling chamber. The bottom of the settling chamber has a bucket-shaped structure. The bottom of the settling shell is connected to a sludge discharge cylinder through a connecting shell, which connects the bucket-shaped bottom of the settling chamber to the inner cavity of the sludge discharge cylinder. A rotating shaft is installed inside the connecting shell and rotatably connected thereto, and a gate is installed on the rotating shaft. An auger passes through the inside of the sludge discharge cylinder.

[0010] Furthermore, the settling shell is provided with a circulating water inlet and a circulating water outlet at both ends along its length.

[0011] Furthermore, a hemispherical flow shroud is installed on the inner side of the circulating water inlet.

[0012] Furthermore, the overflow plate is fixed to the inner wall of the settling shell, and an overflow gap is provided at the top of the overflow plate.

[0013] Furthermore, the flow guide plate is fixed to the inner wall of the settling shell, and a flow gap is provided below the flow guide plate.

[0014] Furthermore, an inclined plate assembly is installed in the cavity between the drainage plate and the overflow plate.

[0015] Furthermore, one end of the rotating shaft is connected to a motor, and the motor drives the gate to rotate 90 degrees through the rotating shaft.

[0016] Furthermore, the length direction of the sludge discharge cylinder is perpendicular to the length direction of the settling shell.

[0017] Furthermore, one end of the auger is connected to the motor; and a sludge discharge port is provided at the lower end of one end of the sludge discharge cylinder.

[0018] Furthermore, a base is installed at the bottom of the sludge discharge cylinder. The bottom of the base is horizontal, and the top of the base has an arc-shaped structure. The top of the base is fixedly connected to the bottom of the sludge discharge cylinder.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0020] In this invention, the sludge in each sludge discharge cylinder can be discharged at regular intervals. During sludge discharge, the motor first drives the gate to rotate 90 degrees through the shaft, turning the gate from a vertical position to a horizontal position, thus sealing the inner cavity of the connecting shell horizontally. Then, another motor drives the auger to rotate, outputting the settled sludge in the sludge discharge cylinder, thus achieving online sludge discharge. By sealing the inner cavity of the connecting shell, the sludge discharge action of the auger is prevented from causing the settled sludge to be carried back into the water above, solving the problem of turbid water caused by the sludge discharge action in the prior art.

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figures 1-3 As shown in the figure, this utility model provides a circulating water sludge removal device, including a settling shell 1, with a circulating water inlet 2 and a circulating water outlet 3 at both ends along the length direction of the settling shell 1.

[0028] The settling shell 1 has multiple settling chambers 4 arranged side by side inside. An overflow plate 8 is provided between adjacent settling chambers 4. The overflow plate 8 is fixed to the inner wall of the settling shell 1, and an overflow gap is provided at the top of the overflow plate 8.

[0029] A flow guide plate 9 is fixedly installed in the middle of the settling chamber 4. The flow guide plate 9 is fixed to the inner wall of the settling shell 1. A flow gap is provided below the flow guide plate 9, and the flow guide plate 9 guides the circulating water from top to bottom.

[0030] An inclined plate assembly 10 is installed in the cavity between the diversion plate 9 and the overflow plate 8. The inclined plate assembly 10 is used to improve the flow state of the circulating water and create conditions for particle sedimentation.

[0031] The bottom of the settling chamber 4 has a bucket-shaped structure, which facilitates the downward settling and accumulation of sludge.

[0032] The bottom of the settling shell 1 is connected to the sludge discharge cylinder 5 via a connecting shell 6. The connecting shell 6 connects the bucket-shaped bottom of the settling chamber 4 to the inner cavity of the sludge discharge cylinder 5. The connecting shell 6 and the settling chamber 4 are arranged in a one-to-one correspondence.

[0033] A rotating shaft 11 is installed inside the communicating shell 6 and is rotatably connected thereto. A gate 12 is installed on the rotating shaft 11. One end of the rotating shaft 11 is connected to a motor. The motor can drive the gate 12 to rotate 90 degrees through the rotating shaft 11. The gate 12 can control the opening and closing of the cavity inside the communicating shell 6 during rotation.

[0034] The length direction of the sludge discharge cylinder 5 is perpendicular to the length direction of the settling shell 1.

[0035] The sludge discharge cylinder 5 is equipped with an auger 13, one end of which is connected to a motor. A sludge discharge port 14 is located below one end of the sludge discharge cylinder 5. The motor drives the auger 13 to rotate, thereby discharging the settled sludge in the sludge discharge cylinder 5 from the sludge discharge port 14.

[0036] A hemispherical flow hood 7 is installed on the inner side of the circulating water inlet 2. By setting the flow hood 7, the flow velocity and kinetic energy of the circulating water are reduced, which is conducive to settling.

[0037] The bottom of the sludge discharge cylinder 5 is equipped with a base 15. The bottom of the base 15 is horizontal and the top of the base 15 is arc-shaped. The top of the base 15 is fixedly connected to the bottom of the sludge discharge cylinder 5.

[0038] The specific working principle of this utility model is as follows:

[0039] The circulating water enters the settling shell 1 through the circulating water inlet 2. First, the flow velocity and kinetic energy are reduced by the flow damper 7. The circulating water then enters each settling chamber 4 in sequence to achieve multi-stage settling. The circulating water flows downward and then upward in the settling chamber 4. The sludge in the circulating water will settle and accumulate at its bucket-shaped bottom. The settled sludge then enters the sludge discharge cylinder 5 through the inner cavity of the connecting shell 6. The settled circulating water is then discharged from the circulating water outlet 3 and enters the circulating water pool.

[0040] The sludge in each sludge discharge cylinder 5 can be discharged at regular intervals. During sludge discharge, the motor first drives the gate 12 to rotate 90 degrees through the rotating shaft 11, so that the gate 12 in the vertical state turns into the horizontal state, and the inner cavity of the connecting shell 6 is closed in the horizontal direction. Then, another motor drives the auger 13 to rotate, and outputs the settled sludge in the sludge discharge cylinder 5 to achieve online sludge discharge. By closing the inner cavity of the connecting shell 6, the sludge discharge action of the auger 13 is prevented from causing the settled sludge to be carried back into the water above, resulting in turbid water.
