Description

Technical Field

[0001] This utility model relates to the field of silt solidification and cleaning technology, specifically to a biological solidification treatment device for river and lake bottom sediment. Background Technology

[0002] Biological solidification treatment equipment for river and lake sediments mainly uses microorganisms, enzymes, or biochemical processes, combined with physical dehydration or chemical stabilization technologies, to achieve the harmlessness, reduction, and resource utilization of sediments.

[0003] The biological solidification treatment of river and lake sediments mainly consists of three steps: mixing of compound bio-enzymes, stirring and compaction, and dewatering. In order to improve the efficiency of sediment solidification, it is necessary to add compound bio-enzymes and surfactants to the sediment to promote the decomposition of organic matter and particle agglomeration. Mixing requires the use of a stirring and mixing device. However, due to the high viscosity of the sediment, poor mixing uniformity is easy to occur during mixing, and the compound bio-enzymes are not easy to fully contact and react with the sediment, thus affecting the solidification efficiency.

[0004] There is an urgent need for a biological solidification treatment device for river and lake bottom sediments to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a biological solidification treatment device for river and lake bottom sediments to solve the problem of poor uniformity of mixing reaction mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biological solidification treatment device for river and lake sediment, comprising a first mixing tank, a second mixing tank fixedly connected to the top of the first mixing tank, a first motor fixedly installed on both sides of the first mixing tank, a mixing shaft fixedly connected to the output end of the first motor, a high-shear emulsifying head fixedly connected to the end of the mixing shaft, a support fixedly connected to the left side of the second mixing tank, a biological enzyme storage tank fixedly installed inside the support, a residual material sensor fixedly connected to the left side of the bottom of the biological enzyme storage tank, and a metering pump fixedly installed at the top of the support.

A liquid level sensor is fixedly installed on the top of the left side of the interior of the second mixing tank. A PLC controller is fixedly installed on the right side of the second mixing tank.

[0007] As a further technical solution of this utility model, the mixing shaft is provided in two sets, the mixing shaft is embedded in both sides inside the first mixing tank, and the scraper is attached to the inner wall of the second mixing tank.

[0008] As a further technical solution of this utility model, both the discharge pipe and the outlet pipe are equipped with solenoid valves, and the bottom end of the discharge pipe is fixedly connected to the top end of the first mixing tank.

[0009] As a further technical solution of this utility model, both the residual material sensor and the liquid level sensor are electrically connected to the PLC controller.

[0011] As a further technical solution of this utility model, a reserved hole is provided at the center of the spreading disc, and a guide pipe is fixedly connected inside the spreading disc.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the biological solidification treatment equipment for river and lake bottom sediment not only achieves the functions of enhancing mixing uniformity and efficiency and facilitating uniform feeding, but also facilitates cleaning.

[0013] (1) By setting up a first mixing tank, a first motor, a high-shear emulsifying head, a second mixing tank, a second motor, and a spiral mixing shaft, the bottom sediment of the river and lake first enters the interior of the second mixing tank. Then, the metering pump delivers the biological enzyme to the interior of the second mixing tank to mix with the bottom sediment. The second motor drives the spiral mixing shaft to fully mix it. After mixing, it enters the interior of the first mixing tank through the discharge pipe. The first motor drives the mixing shaft to rotate. The high-shear emulsifying head on the mixing shaft breaks up micron-sized particles to ensure that the biological enzyme penetrates evenly and achieves full and uniform mixing. This structure realizes the function of facilitating the enhancement of mixing uniformity.

[0014] (2) By setting up a residual material sensor, metering pump, connecting pipe, spreading plate and discharge port, the metering pump can transport the compound bio-enzyme inside the bio-enzyme storage tank to the inside of the second mixing tank and mix it with the bottom mud. The metering pump can quantitatively transport the compound bio-enzyme to the inside of the spreading plate. The compound bio-enzyme is evenly discharged from the discharge port of the spreading plate into the bottom mud of the second mixing tank. This structure realizes the function of easy and uniform feeding.

One set is a connecting pipe for conveying compound biological enzymes, and the other set is a water receiving pipe for conveying cleaning liquid. When the first mixing tank and the second mixing tank need to be cleaned, the valve on the connecting pipe can be closed, and then water can be injected into the spreading plate through the water receiving pipe. The cleaning liquid is evenly discharged from the discharge port along the guide pipe and enters the second mixing tank for rinsing and cleaning. This structure realizes the function of easy cleaning. Attached Figure Description

[0023] Two sets of mixing shafts 3 are provided. The mixing shafts 3 are embedded on both sides inside the first mixing tank 1.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, river and lake bottom sediment first enters the interior of the second mixing tank 12. Then, the metering pump 7 delivers bio-enzymes into the interior of the second mixing tank 12 to mix with the bottom sediment. The second motor 9 drives the spiral mixing shaft 14 to fully mix the sediment. After mixing, the sediment enters the interior of the first mixing tank 1 through the discharge pipe 16. The first motor 2 drives the mixing shaft 3 to rotate. The high-shear emulsifying head 17 on the mixing shaft 3 breaks down micron-sized particles to ensure that the bio-enzymes penetrate evenly and achieve full and uniform mixing.

The cleaning liquid is evenly discharged from the discharge port 19 along the guide pipe 20 and enters the second mixing tank 12 for rinsing and cleaning.

[0029] Working principle: River and lake sediment first enters the second mixing tank 12. Then, metering pump 7 delivers bio-enzymes into the second mixing tank 12 to mix with the sediment. The second motor 9 drives the spiral mixing shaft 14 to fully mix the sediment. After mixing, the sediment enters the first mixing tank 1 through the discharge pipe 16. The first motor 2 drives the mixing shaft 3 to rotate. The high-shear emulsifying head 17 on the mixing shaft 3 breaks down micron-sized particles, ensuring uniform penetration of the bio-enzymes and achieving thorough and uniform mixing. Metering pump 7 can quantitatively deliver the compound bio-enzymes into the spreading disc 11. The compound bio-enzymes are evenly discharged from the outlet 19 of the spreading disc 11.

The residual material sensor 4 can detect the residual material inside the bio-enzyme storage tank 6 and promptly remind the packing. The top of the spreading plate 11 is connected to two sets of interfaces: one is a connecting pipe 8 for conveying the compound bio-enzyme, and the other is a water receiving pipe 10 for conveying the cleaning liquid. When it is necessary to clean the first mixing tank 1 and the second mixing tank 12, the valve on the connecting pipe 8 can be closed, and then water can be injected into the spreading plate 11 through the water receiving pipe 10. The cleaning liquid is evenly discharged from the outlet 19 along the guide pipe 20 and enters the second mixing tank 12 for rinsing and cleaning.
