Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment and relates to a sludge treatment device, in particular to an oil-containing sludge residue analysis and solidification treatment device. Background Art

[0002] In recent years, the pyrolysis technology of oily sludge has attracted much attention at home and abroad as a relatively advanced oily sludge treatment technology. This process can achieve the harmlessness and reduction of oily sludge, but the resource utilization of pyrolysis residues is still in the exploratory stage. Although some studies have used pyrolysis residues as biochar for soil improvement, it has not yet been widely used due to concerns about the secondary cumulative pollution of the soil caused by heavy metals and harmful substances contained in the pyrolysis products of oily sludge. In addition, the current existing technology lacks relevant oily sludge residue analysis and treatment equipment, which cannot meet the needs of oily sludge residue discharge in different regions. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, such as the lack of an oily sludge residue parsing and treatment device and the inability to meet the discharge requirements of oily sludge residues in different regions, the utility model proposes an oily sludge residue parsing and solidification treatment device, by which the oily sludge residue can be parsed and separated to meet the requirements for the solidification and discharge of oily sludge separation and treatment residues in different regions.

[0004] The oily sludge residue analysis and solidification treatment device provided in this application adopts the following technical solution:

[0005] The oily sludge residue parsing and solidification treatment device comprises a frame; characterized in that the device also comprises:

[0006] A mixing bin, connected and fixed to the frame;

[0007] A residue conveying mechanism, connected to one end of the mixing bin and used for conveying oily sludge residue;

[0008] A curing agent injection mechanism is connected to the other end of the mixing chamber and is used for injecting curing agent;

[0009] A stirring mechanism, connected and arranged inside the mixing bin, for stirring the residual material in the mixing bin;

[0010] A solidification bin, arranged below the mixing bin, for solidifying the residual material;

[0011] The material discharging and conveying mechanism is connected between the mixing bin and the solidifying bin and is used for conveying the material in the mixing bin to the solidifying bin.

[0012] By adopting the above technical scheme, the oily sludge residue is transported to the mixing bin by the residue conveying mechanism, the curing agent is injected into the mixing bin by the curing agent injection mechanism, and is fully mixed under the action of the stirring mechanism. The mixed material is transferred to the curing bin under the action of the discharging and conveying mechanism to start the curing reaction. After the reaction is completed, the discharge port is opened to discharge the solidified residue.

[0013] Furthermore, the residue conveying mechanism and the material discharging conveying mechanism are both tubular spiral conveying augers driven by motors.

[0014] By adopting the above technical solution, the tubular spiral conveying auger can evenly and continuously complete the transportation of residual raw materials.

[0015] Furthermore, the stirring mechanism is composed of a motor and a stirring rod, the motor is connected and fixed to the outside of the mixing bin, the stirring rod is placed in the mixing bin, and the stirring rod is driven and connected by the motor.

[0016] By adopting the above technical solution, the stirring mechanism is set to achieve rapid and full fusion of the raw materials and the curing agent, thereby improving work efficiency.

[0017] Furthermore, the curing agent injection mechanism is composed of a one-way valve, a curing agent cylinder and a piston push rod. The one-way valve is arranged between the curing agent cylinder and the mixing chamber. The piston push rod is operatively connected to the curing agent cylinder. The one-way valve is a normally closed one-way valve.

[0018] By adopting the above technical solution, after the residue composition is determined, the corresponding curing agent can be selected, and the curing agent is injected into the mixing chamber by the piston push rod in the curing agent cylinder. The setting of the one-way valve can realize quantitative or timed addition of the curing agent on the one hand, and isolate the mixing chamber from the curing agent cylinder on the other hand.

[0019] Furthermore, the bottom of the mixing bin is a hemispherical structure, the solidifying bin is a cylindrical barrel structure, and there are two solidifying bins, which are symmetrically arranged around the center of the bottom of the mixing bin.

[0020] By adopting the above technical solution, the hemispherical structure at the bottom of the mixing bin is conducive to the gathering of materials at the bottom of the mixing bin, which is conducive to the later transportation to the curing bin. Two curing bins are set up, which is conducive to the timely curing of incoming materials and improves the curing efficiency.

[0021] Furthermore, a discharge port is provided on the curing bin, the height of the discharge port is equal to the diameter of the curing bin, the width of the discharge port is equal to the length of the curing bin, the discharge port is arranged tangent to the curing bin, and the two discharge ports are arranged opposite to each other.

[0022] By adopting the above technical solution, the discharge port is set tangent to the curing bin, which can reduce the difficulty of discharging materials from the curing bin and speed up the discharge efficiency.

[0023] Furthermore, a photosensitive detector is provided in the curing bin, and the photosensitive detector is installed on the inner wall at the top of the curing bin, so as to facilitate the detection of the curing material and open the curing discharge port to discharge the cured residue.

[0024] By adopting the above technical solution, when the curing bin starts the curing operation, the photosensitive detector can detect it. When it is detected that the material parameters have reached the emission threshold, the information is fed back to the external control end, thereby opening the discharge port and performing the emission operation.

[0025] In summary, the present invention includes at least one of the following beneficial technical effects:

[0026] (1) The device of the utility model has a simple structure and can be directly connected to the upper sludge filter press for use, meeting the compatibility of sludge production line equipment.

[0027] (2) The utility model can select a corresponding solidifying agent according to the solid phase composition of the oily sludge, and solidify the oily sludge through a solidifying agent injection mechanism, so as to meet the analytical solidification treatment of various oily sludges to meet the discharge requirements.

[0028] (3) The utility model can effectively treat the residue after thermal analysis of oily sludge. At the same time, the residue after solidification and separation can meet the industrial waste treatment standards for direct landfill, which can reduce the generation and discharge of hazardous waste and play a protective role in the environment.

The mixed material is fully mixed under the action of the stirring mechanism 3. The mixed material is transferred to the curing bin 7 under the action of the discharge conveying mechanism 5 to start the curing reaction. After the reaction is completed, the discharge port 8 is opened to discharge the solidified residue.

[0035] Example 2

[0036] like Figure 1-2 As shown, in order to achieve uniform and continuous transportation of the residue raw materials, in this embodiment, the residue conveying mechanism 2 and the discharge conveying mechanism 5 are both implemented by spiral conveying augers, and both are driven by their own motors.

[0037] like Figure 1 As shown, in order to achieve rapid and sufficient fusion of the raw materials and the curing agent and improve work efficiency, in this embodiment, a stirring mechanism 3 is set in the mixing bin 1 to achieve this. Specifically, the stirring mechanism 3 is composed of a motor 3-1 and a stirring rod 3-2. The motor 3-1 is connected and fixed to the outside of the mixing bin 1, and the stirring rod 3-2 is placed in the mixing bin 1. The stirring rod 3-2 is driven and connected by the motor 3-1.

Specifically, the curing agent injection mechanism 4 is composed of a one-way valve 4-1, a curing agent cylinder 4-2 and a piston push rod 4-3. The one-way valve 4-1 is arranged between the curing agent cylinder 4-2 and the mixing chamber 1. The piston push rod 4-3 is operatively connected to the curing agent cylinder 4-2.
