Description

Technical Field

[0001] This application belongs to the technical field of hydrothermal hydrolysis, and particularly relates to a waste hydrothermal hydrolysis treatment device. Background Art

[0002] Hydrothermal hydrolysis is to hydrolyze organic wastes such as livestock and poultry manure, straw, Chinese medicine residues, food waste, and urban sludge under high temperature and high pressure conditions, decompose macromolecular fibrous organic matter into small molecular polysaccharide-based nutrients, and at the same time kill various bacteria and pathogens to become high-quality liquid or solid organic fertilizers.

[0003] Currently, a crushing device is used to crush straw-like wastes before the hydrothermal hydrolysis treatment of agricultural wastes. However, most of the current crushing devices adopt a fixed stirring and crushing mechanism, and directly pour out after a fixed crushing time. Such a method is difficult to ensure the crushing quality and comprehensiveness, thereby affecting the efficiency of subsequent hydrothermal hydrolysis. Summary of the Utility Model

[0005] In order to achieve the above purpose, the present application adopts the following technical solutions:

A plurality of jacks arranged front and back are opened on the opposite side walls of the crushing tank, and reciprocating rods are movably inserted into the corresponding jacks. One ends of the plurality of reciprocating rods are fixedly connected to the same sieve hole plate. One ends of the plurality of reciprocating rods on the same side located outside the crushing shell are fixedly connected to the same anti-disengagement plate. A plurality of reciprocating springs sleeved on the reciprocating rods are fixedly connected between the anti-disengagement plate and the crushing shell. A U-shaped vertical plate is fixedly installed on the outer wall of the upper end of the crushing shell. A horizontally arranged reciprocating screw rod is rotatably connected to the inner wall of the upper end of the U-shaped vertical plate. A reciprocating seat is threadedly sleeved on the reciprocating screw rod. A crushing motor is fixedly connected to the lower end of the reciprocating seat. A crushing rod is fixedly connected to the lower output end of the crushing motor. A crushing cutter head is fixedly connected to the lower end of the crushing rod. A rotating mechanism for driving the reciprocating screw rod to rotate is fixedly installed at the upper end of the U-shaped vertical plate. Two groups of intermittent extrusion mechanisms for driving the anti-disengagement plate to move are symmetrically and fixedly installed on the outer wall of the crushing shell.

[0007] Preferably, an elastic sealing pad is fixedly connected between the outer wall of the upper end of the sieve hole plate and the inner wall of the crushing tank.

[0008] Preferably, the rotating mechanism includes a rotating motor fixedly installed at the upper end of the U-shaped vertical plate. The output end of the rotating motor is fixedly connected with a driving sprocket. A driven sprocket is threadedly sleeved on the rod wall of the reciprocating screw rod. A transmission chain is sleeved between the driving sprocket and the driven sprocket for transmission.

[0009] Preferably, a limiting slider is fixedly connected to the upper end of the reciprocating seat. A limiting sliding groove matched with the limiting slider is formed at the lower end of the horizontal part of the U-shaped vertical plate for sliding connection.

[0010] Preferably, the intermittent extrusion and pushing mechanism includes a bearing seat fixedly connected to the outer wall of the crushing shell. A transmission shaft is rotatably sleeved on the inner wall of the bearing seat through a ball bearing.

[0011] Preferably, the driven bevel gear is a small-diameter gear, and the driving bevel gear is a large-diameter gear.

[0012] Compared with the prior art, the present application provides a waste hydrothermal treatment device, which has the following beneficial effects:

[0013] For this waste hydrothermal treatment device, through the provided hydrolysis tank and crushing tank, the waste to be hydrolyzed is put into the crushing shell. The rotating motor and the crushing motor are started. The crushing motor drives the crushing rod and the crushing cutter head to rotate, quickly crushing the waste. The rotating motor drives the driving sprocket to rotate, and through the transmission chain, the driven sprocket is driven to rotate synchronously, and then the reciprocating screw rod is driven to rotate. Through the threaded socket action of the reciprocating screw rod and the reciprocating seat, the reciprocating seat drives the crushing cutter head to move back and forth, increasing the crushing range. Moreover, the reciprocating screw rod drives the driving bevel gear to rotate synchronously. Through the meshing action of the driving bevel gear and the driven bevel gear, the transmission shaft is driven to drive the cam to continuously rotate on the side of the anti-detachment plate.
