Description
Technical Field

The existing sludge dewatering machine will vibrate after long-term operation, which can easily cause damage to the internal components of the sludge dewatering machine. When the existing sludge dewatering machine discharges sludge, the sludge will spray outward when discharged from the dewatering box due to the continuous operation of the extrusion wheel, polluting the environment and being difficult to collect.

[0011] Technical effects and advantages of the utility model:
[0012] 1. The utility model starts the first motor to rotate the driving gear after the sludge enters the sludge inlet when the dewatering machine is started. After the driving gear rotates, the first gear and the second gear begin to rotate. After the first gear begins to rotate, the first transmission rod begins to rotate. At this time, the stirring rod rotates in the reaction box. At this time, the pneumatic valve starts to work and controls the forward and backward movement of the movable rod to move the push block left and right. After the push block begins to move, the movable plate moves in the discharge port. When the movable plate moves to one side, the flocculant in the storage box slides downward, and when the movable plate moves to the other side, the flocculant stops falling. This is beneficial in that the flocculant can be dropped from the storage box to the reaction box through the movement of the movable plate on the discharge port, reducing the labor cost of manual addition. The stirring of the stirring rod in the reaction box can make the flocculant react with the sludge quickly to improve the work efficiency.
[0013] 2. In the utility model, when the equipment vibrates, the top plate moves downward. At this time, the round block presses down the first spring to contact the square block and perform shock absorption. When the top plate moves downward and interacts, the first connecting block moves downward and causes the driving rod to move. When the driving rod moves, the second connecting block drives the moving block to move on the round rod. At this time, the second spring is subjected to force for shock absorption, which is beneficial through the setting force of the first spring and the second spring, so that the dehydrator body has a buffering effect when vibration occurs, thereby avoiding the vibration generated by the dehydrator body during long-term operation, which may cause damage to the internal components of the dehydrator body.
[0014] 3. In the utility model, when the second motor is started, the second transmission rod rotates to make the extrusion wheel start to rotate. At this time, the connecting pipe transfers the sludge in the reaction box to the extrusion wheel in the dehydration box to squeeze the water in the sludge, and the sludge is discharged through the sludge discharge port. At this time, the first baffle and the second baffle are arranged to make the sludge fall between the two baffles, which facilitates the collection of the sludge. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The working principle of the utility model is as follows: when the dehydrator is started, after the sludge enters the sludge inlet 101, the first motor 2 is started to rotate the driving gear 201. After the driving gear 201 rotates, the first gear 202 and the second gear 203 start to rotate. After the first gear 202 starts to rotate, the first transmission rod 204 starts to rotate. At this time, the stirring rod 205 rotates in the reaction box 1. At this time, the pneumatic valve 306 starts to work by controlling the forward and backward movement of the movable rod 305 to make the push block 304 move left and right. When the push block 304 starts to move After the movable plate 303 is moved, it moves in the discharge port 301.

When the second motor After 405 is started, the second transmission rod 406 rotates to make the squeezing wheel 407 start to rotate. At this time, the connecting pipe 102 transfers the sludge in the reaction box 1 to the squeezing wheel 407 in the dehydration box 4 to squeeze the water in the sludge, and the sludge is discharged through the sludge discharge port 403. At this time, the first baffle 402 and the second baffle 404 are set to allow the sludge to fall between the two baffles, which facilitates the collection of the sludge; when the equipment vibrates, the top plate 6 moves downward, and at this time the round block 601 presses down the first spring 602 to contact the square block 603 and Shock absorption is carried out, and when the top plate 6 moves downward and interacts, the first connecting block 7 moves downward and causes the driving rod 701 to move. When the driving rod 701 moves, the second connecting block 702 drives the moving block 703 to move on the round rod 704. At this time, the second spring 706 is subjected to force for shock absorption, which is beneficial to the setting force of the first spring 602 and the second spring 706, so that the dehydrator body has a buffering effect when vibration occurs, thereby avoiding the vibration generated by the dehydrator body during long-term operation, which may cause damage to the internal components of the dehydrator body.
