Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a reaction tank of sludge treatment equipment. Background Art

[0002] Inclined plate sedimentation tanks, also known as inclined tube sedimentation tanks, are an improved type of sedimentation tank that incorporates a set of parallel plates (or square tubes) within the sedimentation zone of a conventional sedimentation tank to shorten sedimentation time and improve sedimentation efficiency. Designed based on the principle of "shallow sedimentation," these tanks utilize parallel inclined plates to enhance sedimentation efficiency. Each pair of parallel inclined plates creates a shallow sedimentation basin, allowing the treated water (or wastewater) and settled sludge to interact and separate within the shallow sedimentation layer. The separated sludge then slides down the inclined plates under gravity to the tank bottom for centralized disposal.

[0003] However, after the sludge from the inclined plate sedimentation tank is discharged into the sludge tank, it often becomes clogged. This is because the properties of the sludge in each wave of sewage vary. Factors such as the size, shape, density, and moisture content of the solid particles in the sludge affect its flowability in the sludge tank. If the sludge particles are large, irregular in shape, or have a high moisture content, they may cause blockage in the sludge tank. Therefore, a reaction tank in the sludge treatment equipment is proposed to solve this problem. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the present invention is to provide a reaction tank of sludge treatment equipment to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned object, an embodiment of one aspect of the present invention provides a reaction tank of a sludge treatment equipment, comprising a tank mouth, a tank body, a sludge tank, and a bracket, wherein the bottom of the tank mouth is fixedly connected to the tank body, the bottom of the tank body is fixedly connected to the sludge tank, and the outer side of the tank body is fixedly connected to the bracket;

[0007] A plurality of water troughs are fixedly connected to the inner side of the pool mouth. The water troughs are open-top structures. The ends of the water troughs are fixedly connected to water outlet pipes. A plurality of leakage holes are opened on the side walls of the water troughs.

[0008] The side of the pool mouth is fixedly connected with a water inlet pipe, the pool body is inclined, and the interior of the pool body is fixedly connected with a plurality of inclined plates;

[0009] The sludge tank is in an inverted cone shape as a whole, and the bottom end of the sludge tank is fixedly connected to a sludge outlet;

[0010] A plurality of oblique water injection ports are fixedly connected to the outer side of the tank wall of the sludge tank. The water injection ports are arranged in a circular array around the axis of the sludge tank, and a cover body is installed at the end of the water injection port.

[0011] Preferably, any of the above schemes is that the bottom of the pool mouth is connected to the pool body and the sludge tank in sequence, and the water tank is installed horizontally.

[0012] Adopting the above technical solution: this reaction tank is composed of a tank mouth, a tank body and a sludge tank from top to bottom, and this reaction tank is supported by a bracket.

[0013] Preferably, any of the above schemes is that the water trough is welded to the pool mouth, and a plurality of inclined plates are provided below the water trough.

[0014] Adopt the above technical scheme: The working principle of this reaction tank is to treat sewage and sludge.

[0015] Wastewater enters the tank through the inlet pipe. After entering the inclined plate tank, it flows between the plates. Heavy solid particles settle onto the plates due to gravity. These settled solid particles slide down the plates and eventually fall into the sludge tank. Clarified water flows over the plates, is collected in a trough, and is discharged through the outlet pipe.

[0016] The sludge tank has a mud outlet, which is connected to the mud suction pump equipment. When the mud washing pump is working, the sludge in it can be pumped away.

[0017] Preferably, any of the above solutions is that the leakage hole is opened horizontally, and the water inlet pipe is located below the water outlet pipe.

[0018] Preferably, any of the above solutions is that the sludge tank is welded to the bottom of the tank body, and the diameter of the sludge tank decreases from top to bottom.

[0019] Adopting the above technical solution: the core structure of the device is: sludge tank, mud outlet, water injection port and cover body.

[0020] The sludge tank for collecting sludge is designed to be inverted conical in shape, with a mud outlet at the bottom. Four oblique water inlets are installed on the upper part of the side wall of the sludge tank. The top has a cover. When the cover is opened, the water inlets can be connected to a fire water source, spraying water into the sludge tank in four directions. The water flows toward the center of the sludge tank, effectively stirring the sludge and diluting and redistributing the sludge that may have settled or agglomerated. This design can quickly form a fluid channel inside the sludge tank, significantly reducing the viscosity and resistance of the sludge and improving the fluidity of the sludge. This allows it to be discharged quickly and effectively prevents clogging of the sludge tank. As the sludge fluidity increases, the sludge can be discharged more smoothly through the mud outlet, effectively avoiding the problem of sludge accumulation and clogging in the tank. This not only improves the efficiency of sludge treatment, but also reduces equipment failure and maintenance costs caused by sludge blockage.

[0021] The inverted conical sludge tank design allows sludge to more easily gather at the bottom under the action of gravity and be discharged through the mud outlet. At the same time, the location of the inclined water inlet also takes into account the flow characteristics of the sludge, ensuring that the flushing water flow can fully cover and agitate the sludge, reducing sludge accumulation and agglomeration on the tank wall.

[0022] Preferably, any of the above schemes has an inclination angle of 30-50 degrees and a spacing angle of 90 degrees.

[0023] Preferably, any of the above solutions is that the cover is threadedly connected to the water inlet.

[0024] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0025] The reaction tank of this sludge treatment equipment is designed with a sludge tank, a sludge outlet, a water inlet, and a cover. The sludge tank for collecting sludge is designed in an inverted cone shape, with the sludge outlet at the bottom and four oblique water inlets installed on the upper part of the sludge tank's side wall. The top of the sludge tank has a cover. When the cover is opened, the water inlets can be connected to a fire water source, spraying water into the sludge tank in four directions. The water flows toward the center of the sludge tank, effectively agitating the sludge and diluting and redistributing sludge that may have previously settled or agglomerated. This design quickly forms a fluid channel inside the sludge tank, significantly reducing the viscosity and resistance of the sludge and improving its fluidity. This allows for rapid discharge and effectively prevents sludge tank clogging. As the sludge fluidity increases, the sludge can be discharged more smoothly through the sludge outlet, effectively avoiding the problem of sludge accumulation and clogging within the tank. This not only improves the efficiency of sludge treatment, but also reduces equipment failures and maintenance costs caused by sludge clogging.

[0026] The inverted conical sludge tank design allows sludge to more easily gather at the bottom under the action of gravity and be discharged through the mud outlet. At the same time, the location of the inclined water inlet also takes into account the flow characteristics of the sludge, ensuring that the flushing water flow can fully cover and agitate the sludge, reducing sludge accumulation and agglomeration on the tank wall.

[0037] Several water troughs 5 are fixedly connected to the inner side of the pool mouth 1. The water troughs 5 are open-top structures. The ends of the water troughs 5 are fixedly connected to the water outlet pipes 6. Several leakage holes 7 are opened on the side walls of the water troughs 5.

[0038] The side of the pool mouth 1 is fixedly connected with a water inlet pipe 8, the pool body 2 is tilted, and the interior of the pool body 2 is fixedly connected with a plurality of inclined plates 9;

[0039] The sludge tank 3 is in an inverted cone shape as a whole, and a sludge outlet 10 is fixedly connected to the bottom end of the sludge tank 3;

[0040] A plurality of oblique water injection ports 11 are fixedly connected to the outer side of the tank wall of the sludge tank 3 . The water injection ports 11 are arranged in a circular array around the axis of the sludge tank 3 . A cover 12 is installed at the end of the water injection port 11 .

[0041] Example 1: The bottom of the tank opening 1 is connected to the tank body 2 and sludge tank 3 in sequence, with a water trough 5 installed horizontally. This reaction tank comprises, from top to bottom, the tank opening 1, the tank body 2, and the sludge tank 3. The reaction tank is supported by a bracket 4. The water trough 5 is welded to the tank opening 1, and below it are multiple inclined plates 9.

[0042] Example 2: Leakage hole 7 is horizontally defined, and water inlet pipe 8 is located below water outlet pipe 6. Sludge tank 3 is welded to the bottom of tank body 2, with the diameter of sludge tank 3 decreasing from top to bottom. Water inlet 11 is tilted at an angle of 30-50 degrees, and is spaced 90 degrees apart. Cover 12 is threadedly connected to water inlet 11.

[0043] The working principle of this utility model is as follows:

[0044] The working principle of this reaction tank is to treat sewage and sludge.

[0045] Wastewater enters the tank inlet 1 through inlet pipe 8. After entering the inclined plate tank body 2, the wastewater flows between the inclined plates 9. Solid particles with higher specific gravity settle onto the inclined plates 9 under the action of gravity. The settled solid particles slide downward along the inclined plates 9 and eventually fall into the sludge tank 3. The clarified water flows over the inclined plates 9, is collected in the water tank 5, and is discharged through the outlet pipe 6.

[0046] The sludge tank 3 has a sludge outlet 10 connected to a sludge suction pump device. When the sludge washing pump is working, the sludge therein can be pumped away.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] The reaction tank of the sludge treatment equipment is designed to be an inverted cone through the coordinated arrangement of the sludge tank 3, the mud outlet 10, the water injection port 11 and the cover 12. The bottom of the sludge tank 3 is designed to be an inverted cone, and the mud outlet 10 is installed on the upper part of the side wall of the sludge tank 3. Four oblique water injection ports 11 are installed on the top of the sludge tank 3. The top of the sludge tank 3 has a cover 12. When the cover 12 is opened, the water injection port 11 can be connected to the fire water source, and four-way water flow is sprayed into the sludge tank 3. The water flow impacts the center of the sludge tank 3, which can effectively stir the sludge, so that the sludge that may have been deposited or agglomerated is diluted and redistributed. This design can quickly form a fluid channel inside the sludge tank, significantly reducing the viscosity and resistance of the sludge and improving the fluidity of the sludge. It can be discharged quickly and effectively prevent the sludge tank 3 from being blocked. As the sludge fluidity increases, the sludge can be discharged more smoothly through the mud outlet 10, effectively avoiding the problem of sludge accumulation and blockage in the tank. This not only improves the efficiency of sludge treatment, but also reduces equipment failure and maintenance costs caused by sludge blockage.

[0049] The inverted conical design of the sludge tank 3 allows sludge to more easily gather at the bottom under the action of gravity and be discharged through the sludge outlet. At the same time, the location of the oblique water inlet also takes into account the flow characteristics of the sludge, ensuring that the flushing water flow can fully cover and agitate the sludge, reducing sludge accumulation and agglomeration on the tank wall.
