[0002] Sludge dewatering refers to a sludge treatment method that removes moisture from flowing primary, concentrated or digested sludge and converts it into semi-solid or solid mud blocks. After dehydration, the sludge moisture content can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dewatering equipment.

[0003] The patent with patent announcement number CN212982754U relates to a sludge dewatering device for environmental protection, including a support frame, a first motor and a second motor, a dewatering cylinder is rotatably installed between the top ends of the support frames, and support rods are fixed on both sides of the top ends of the support frames, and a top plate is fixed between the top ends of the two support rods; the second motor is installed on the top plate, and the output shaft of the second motor extends to the bottom of the top plate, and a screw rod is concentrically fixed on the output shaft of the second motor, and the support plate is threadedly connected to the screw rod, and guide rods are arranged on both sides of the screw rod, the guide rod is parallel to the screw rod, and the guide rod passes through the support plate, and the top end of the guide rod is fixed on the top plate, and the second motor drives the pressure plate to descend to press and dehydrate the sludge in the dewatering cylinder to remove moisture in the sludge, which is convenient for sludge processing, and its structure is simple and the production cost is low.

[0004] In the above patent, the second motor drives the pressure plate to descend to press and dehydrate the sludge in the dewatering cylinder to remove moisture from the sludge, which is convenient for sludge treatment. It has a simple structure and low production cost. However, flocculants need to be added before the sludge is treated, and the flocculants may become damp and agglomerated if they remain stationary in the device for a long time.

[0014] The present invention provides a sludge dewatering device for environmental protection, which has the following beneficial effects: (1) In this invention, when the motor is started, the switch rod contacts the switch block, and the drug feed slide plate is intermittently opened, so that the flocculant intermittently and evenly enters the stirring chamber, preventing the flocculant from entering all at once, resulting in a reduction in the contact area with the sludge and a reduction in the effect of the flocculant. The connecting rod drives the moving rod to move, and the movement of the moving rod drives the inclined block and the moving rod to move. The inclined block drives the flocculant to move toward the drug feed port, and the moving rod drives the swing plate to swing, thereby breaking up the accumulated flocculant and preventing the flocculant piled below from agglomerating, which reduces the effect of the flocculant and causes a decrease in the reaction efficiency between the flocculant and the sludge.

When the inclined surface of the lifting block is out of contact with the connecting rod, the connecting rod falls and hits the filter plate. At the same time, the spring between the filter plate and the machine body is compressed and then reset to vibrate the filter plate, thereby removing impurities on the filter plate and preventing the filter holes on the filter plate from being blocked by sludge, thereby reducing the filtering efficiency of sewage.

[0016] (3) In this invention, when the hydraulic plate moves upward, it drives the lifting rod to move upward together. The lifting rod moves upward, which drives the lifting rod to move upward. The lifting rod moves upward and drives the scraper to move toward the discharge pipe, thereby scraping the sludge on the filter plate and driving the sludge to move toward the discharge pipe to improve the sludge discharge efficiency. At the same time, the scraper drives the push rod to move toward the discharge pipe, the push rod contacts the start rod, the valve opens, and the discharge pipe opens.
