Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to a high-efficiency sludge conditioner. Background Art

[0002] In the sludge solidification and dewatering industry, sludge and coagulant (powder) cannot be dissolved evenly in time after being mixed, resulting in accumulation around the homogenization tank, which takes up space. The diffusion of coagulant dust affects the environment and seriously affects the efficiency of the subsequent process (plate and frame filter press dewatering), while increasing the cost of the coagulant.

[0003] In order to solve the above problems, we designed a high-efficiency sludge conditioner. In the sealed structure conditioner, the lower layer of sludge after the continuous flow of sludge and the coagulant are fully mixed is pressure-loaded through the culvert, and the evenly mixed sludge is promptly overflowed to the next process (plate and frame filter press dehydration). This effectively solves the uniformity of sludge conditioning, the timeliness of sludge transportation and the cost control of the coagulant, and will not affect the space requirements of the conditioner. At the same time, the conditioner has low power consumption, small space occupation, simple operation, environmental protection and high efficiency. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a high-efficiency sludge conditioner to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-efficiency sludge conditioner, comprising a mixing box and an output box arranged on one side of the mixing box and connected thereto, the inner cavity of the mixing box is provided with a stirring assembly, the top of the mixing box is respectively connected to a sludge pressurized culvert and a solidifying agent input pipe, a partition is fixedly connected to the connection between the output box and the mixing box, the bottom of the partition is fixedly connected to a filter screen, the bottom of the filter screen is fixedly connected to the bottom of the inner cavity of the mixing box, a connecting rod is fixedly connected to the surface of the stirring assembly, one end of the connecting rod is fixedly connected to a push plate, a plurality of connecting rods are provided, and the length gradually increases, the surface of the push plate connected to the longest connecting rod abuts against the surface of the filter screen, after the solidifying agent and the sludge are input into the mixing box, they are stirred through the stirring assembly, and then transported to the push plate. The stirring assembly drives the push plate to rotate through the connecting rod, and gradually squeezes the sludge toward the filter screen. The multiple push plates form a spiral motion through the position setting, and the push plates are squeezed in stages, which can quickly squeeze the sludge to the other side of the filter screen and transport it to the output box. It can not only filter the sludge and crush the oversized particles, but also mix the sludge more fully and achieve better solidification effect. The lower layer of sludge after the continuous sludge and the coagulant are fully stirred is pressure-loaded through the culvert, and the evenly stirred sludge is promptly overflowed to the next process (plate and frame filter press dehydration), which effectively solves the uniformity of sludge conditioning, the timeliness of sludge transportation and the cost control of the coagulant, and will not affect the space requirements of the conditioner. At the same time, the conditioner has low power consumption, small volume, simple operation, and is environmentally friendly and efficient.

[0006] As a further solution of the present invention: a guide arc surface is provided on the surface of the push plate, and the guide arc surface faces the rotation direction of the stirring assembly. Through the setting of the guide arc surface, the push plate can cut into the sludge more smoothly, and the thrust on the sludge is stronger. The combination of the guide arc surfaces between multiple push plates rotates more smoothly.

[0007] As a further solution of the present invention: a ball is fixedly connected to the bottom of the push plate, and a guide groove is provided at the bottom of the inner cavity of the mixing box, which is arranged to roll with the surface of the ball. A scraper is fixedly connected to one side of the push plate, and the surface of the scraper is in contact with the inner cavity of the guide groove. The push plate is supported by the rotation of the ball in the guide groove, and the rotation of the push plate is assisted. The sludge in the guide groove is scraped off by the setting of the scraper, which facilitates the rolling of the ball and makes the overall movement smoother.

[0008] As a further solution of the present invention: the inner cavity of the mixing box is fixedly connected to an annular shielding plate covering the surface of the sludge pressurized culvert and the solidifying agent input pipe, the bottom end of the solidifying agent input pipe is connected to an annular output pipe located in the inner cavity of the annular shielding plate, the surface of the annular output pipe is connected to an injection port, the solidifying agent input pipe is connected to an external pressurizer, and the curing agent is sprayed out from the injection port by high pressure and mixed with the sludge transported in by the sludge pressurized culvert, so that the mixing is more thorough, and then it is directly stirred through the stirring component.

[0009] As a further solution of the present invention: the stirring assembly includes a driving motor fixed above the mixing box, one end of the driving motor output shaft is fixedly connected to a driving shaft rotatably arranged with the inner cavity of the mixing box, the surface of the driving shaft is fixedly connected to a stirring frame, the driving motor drives the driving shaft to rotate, and the driving shaft drives the stirring frame and the push plate to rotate to stir and squeeze the sludge.

[0010] As a further solution of the present invention: the inner cavity of the output box is rotatably connected to a rotating shaft driven by a power mechanism, the bottom of the rotating shaft is fixedly connected to a conveying auger rotatably connected to the bottom of the inner cavity of the output box, the right side of the output box is connected to a discharge port, and the discharge port is located above the mixing box, and the surface of the rotating shaft is fixedly connected to a stirring rod, and the sludge is transported upward by the conveying auger and then discharged through the discharge port. By setting the height difference between the discharge port and the mixing box, the stirring time of the sludge is extended and the treatment effect is better.

[0011] As a further solution of the present invention: an elastic vibration rod is fixedly connected to the top of the inner cavity of the output box, and an elastic toggle section is fixedly connected to one side of the stirring rod. When the rotating shaft rotates, the surface of the elastic toggle section abuts against the surface of the elastic vibration rod. When in use, the stirring rod rotates to drive the elastic toggle section to rotate, impacting the surface of the elastic vibration rod, driving the elastic vibration rod to vibrate continuously, thereby clearing the sludge at the discharge port, preventing the sludge from clogging at the discharge port, and achieving a better discharge effect.

[0012] As a further solution of the present invention: an interrupter plate is fixedly connected to the right side of the inner cavity of the output box, and the interrupter plate is located below the discharge port. By setting the interrupter plate, the travel of the sludge in the output box is further extended.

[0013] When in use, the curing agent is sprayed out from the injection port by high pressure and mixed with the sludge that is pressurized and transported in through the culvert to make the mixing more thorough. The curing agent and the sludge are then stirred directly by the stirring assembly. After the curing agent and the sludge are input into the mixing box, they are stirred by the stirring assembly and then transported to the push plate. The stirring assembly drives the push plate to rotate through the connecting rod, and gradually squeezes the sludge toward the filter screen. The position setting of the multiple push plates forms a spiral motion, and the push plates are squeezed in stages. The surface of the push plate is provided with a guide arc surface, and the guide arc surface faces the rotation direction of the stirring assembly. The setting of the guide arc surface allows the push plate to smoothly cut into the sludge. The thrust of the sludge is stronger, and the combination of the guide arc surfaces between the multiple push plates rotates more smoothly, which can quickly squeeze the sludge to the other side of the filter and transport it to the output box. It can not only filter the sludge and crush the oversized particles, but also mix the sludge more fully and achieve better solidification effect. The sludge is transported upward by the conveying auger and then output through the discharge port. By setting the height difference between the discharge port and the mixing box, the rotation of the stirring rod drives the elastic toggle end to rotate, impacting the surface of the elastic vibration rod, driving the elastic vibration rod to vibrate continuously, and dredging the sludge at the discharge port to prevent the sludge from clogging at the discharge port, and the discharge effect is better.
