[0036] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0037] Reference is made below Figures 1-4 The oil sludge uniform material feeder 100 and the oil sludge pyrolysis device of the embodiments of the present application are described.

[0038] The oil sludge uniform material feeder 100 of the embodiments of the present application comprises a feeding shell 1, a first uniform material conveying member 2 and a second uniform material conveying member 3.

[0039] The feeding shell 1 has a feeding port 11, a discharging port 12 and a feeding passage extending in the up-down direction; the first uniform material conveying member 2 and the second uniform material conveying member 3 are arranged in parallel in the up-down direction, and each of the first uniform material conveying member 2 and the second uniform material conveying member 3 has a bidirectional spiral blade, the center of which is arranged opposite to the feeding port 11 along the up-down direction of the feeding passage.

[0040] The oil sludge uniform material feeder 100 of the embodiments of the present application, by arranging the first uniform material conveying member 2 and the second uniform material conveying member 3 in the feeding passage, and arranging each of the first uniform material conveying member 2 and the second uniform material conveying member 3 to have a bidirectional spiral blade, the oil sludge entering from the feeding port 11 in the form of blocks can be stirred and crushed in the uniform material conveying member by the first uniform material conveying member 2, the area of the oil sludge can be increased, and the agglomeration of the oil sludge can be further reduced, and the uniformity of the oil sludge feeding can be improved. Further, it is helpful to improve the pyrolysis efficiency of the oil sludge in the pyrolysis chamber 200.

[0041] Therefore, the oil sludge uniform material feeder 100 of the embodiments of the present application has the advantages of improving the uniformity of the oil sludge feeding and improving the pyrolysis efficiency of the oil sludge.

[0042] Specifically, the first material uniformizing conveying member 2 is arranged above the second material uniformizing conveying member 3, wherein the bidirectional spiral blade can disperse the falling oil sludge towards two sides. The oil sludge with high liquid content can be extracted into the feeding port 11 of the feeding shell 1 by the oil sludge pool through the oil sludge pump, and then falls onto the first material uniformizing conveying member 2, and is distributed to two sides (for example, left and right sides shown in FIG. 6) through the rotation of the first material uniformizing conveying member 2, and then falls onto the second material uniformizing conveying member 3 and is further distributed to two sides. By controlling the rotation speed of the first material uniformizing conveying member 2 and the second material uniformizing conveying member 3 and the gap of the material uniformizing spiral discharging channel, the continuous and uniform feeding of the oil sludge can be completed, and the thickness of the oil sludge on the chain plate conveyor 300 can be accurately controlled by matching the output capacity of the oil sludge pump and the transmission speed of the chain plate conveyor 300.

[0043] As shown in FIGS. 6 and 7, the oil sludge material uniformizing feeder 100 of the embodiment of the present application further comprises a first material blocking member 4, which is arranged between the first material uniformizing conveying member 2 and the second material uniformizing conveying member 3 in the up-down direction. In other words, the first material uniformizing conveying member 2, the first material blocking member 4 and the second material uniformizing conveying member 3 are sequentially arranged in the up-down direction. Figure 2 Figure 3 The oil sludge material uniformizing feeder 100 of the embodiment of the present application can further avoid the oil sludge entering from the feeding port 11 from directly falling into the pyrolysis chamber 200 by the arrangement of the material blocking plate, and gives the second material uniformizing conveying member 3 a corresponding buffer time, thereby avoiding the problem of poor uniformity of the oil sludge feeding caused by poor continuity of the feeding. Therefore, the oil sludge material uniformizing feeder 100 helps to improve the pyrolysis efficiency of the oil sludge in the pyrolysis chamber 200.

[0044] As shown in FIGS. 6 and 7, the first material blocking member 4 is arranged in a plate-shaped structure inclined relative to the horizontal direction, and the first material uniformizing conveying member 2 and the second material uniformizing conveying member 3 are arranged in a staggered manner in the horizontal direction, and the lower end of the first material blocking member 4 is arranged opposite to the second material uniformizing conveying member 3 in the up-down direction.
