Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to a high-efficiency sludge filter dryer. Background Technology

[0002] Industrial production generates sludge, which contains heavy metals and toxic and harmful organic matter that is difficult to biodegrade. This sludge cannot be treated at the same time as urban sludge using the same treatment methods, so it needs to be treated separately. For sludge containing heavy metals and that is difficult to degrade, it is generally treated by drying, dewatering and then incinerating.

[0003] Currently available sludge dryers cause sludge to clump together on the inner wall of the device after drying, making it inconvenient to remove and clean. This results in inconvenient use of the device and makes it impossible to guarantee that the sludge is completely dried. Therefore, it is necessary to propose a more efficient sludge filter dryer to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient sludge filter dryer that can thoroughly dry sludge and facilitate its removal.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency sludge filter dryer, including a drying chamber, a feed inlet at the top of the drying chamber, a water removal mechanism in the inner cavity, and a drying component at the bottom. The water removal mechanism includes electric push rods symmetrically installed on the left and right side walls of the drying chamber. Each of the two electric push rods has an extrusion plate installed on its output end. The bottom of the drying chamber has a discharge port and a closure for sealing the discharge port. The extrusion plate has a drainage hole, and the outer peripheral wall of the extrusion plate is in contact with the inner wall of the drying chamber.

[0006] By adopting the above technical solution, sludge is poured into the drying chamber through the feed inlet. By driving the electric push rods on both sides, the two extrusion plates are brought together to squeeze the sludge, expel the water, and discharge it through the drain hole for preliminary dewatering. Then, the discharge port is opened through the closing component. At this time, the sludge has a certain moisture content and can be smoothly discharged from the drying chamber. Then, it is further dried by the drying component to make the sludge dry thoroughly. At the same time, the sludge can be easily removed, making the device more convenient to use.

[0007] A further feature of this invention is that the inner cavity of the drying chamber is also provided with four guide rods that are slidably adapted to the extrusion plates on both sides.

[0008] By adopting the above technical solution, the squeezing plates on both sides slide more smoothly under the guidance of the guide rod, thus enabling better squeezing of sludge.

[0009] A further feature of this invention is that the closure includes two connecting plates installed at the bottom of the drying chamber, two symmetrically arranged movable plates and a screw structure for controlling the relative translation of the two movable plates are provided between the two connecting plates, and a baffle for sealing the discharge port is provided at the upper end of the movable plates.

[0010] By adopting the above technical solution, the moving plates on both sides are driven away from each other by the screw structure, which in turn drives the two baffles away, thereby opening the discharge port and discharging the sludge.

[0011] A further feature of this invention is that the lead screw structure includes a first motor mounted on a connecting plate on one side, a bidirectional lead screw adapted to the threads of the two moving plates is mounted on the output end of the first motor, and a crossbar adapted to the sliding of the two moving plates is mounted between the two connecting plates.

[0012] By adopting the above technical solution, the first motor drives the bidirectional lead screw to rotate, and under the guidance and limitation of the crossbars on both sides, the two moving plates move away from or closer to each other, thereby realizing the opening and closing of the discharge port.

[0013] A further feature of this invention is that the drying assembly includes a receiving chamber located below the drying chamber, and the receiving chamber contains a water filter plate and a material throwing mechanism for pushing the water filter plate.

[0014] By adopting the above technical solution, after the sludge enters the receiving hopper, it is thrown upward by the throwing mechanism for further drying treatment.

[0015] A further feature of this invention is that: both sides of the bottom of the drying chamber are provided with water outlets, and the bottom of the water outlets is provided with a water collection channel that connects to the bottom of the inner cavity of the receiving chamber.

[0016] By adopting the above technical solution, the squeezed water enters the bottom of the receiving hopper through the outlet and water collection channel for collection.

[0017] A further feature of this invention is that a drying machine is provided on the side of the top of the receiving hopper.

[0018] By adopting the above technical solution, the sludge is dried by a wind dryer during the sludge throwing process, thereby further improving the sludge drying efficiency.

[0019] A further feature of this invention is that the material throwing mechanism includes a second motor installed on the outer wall of the receiving hopper, a rotating rod installed at the output end of the second motor, two cams installed on the rotating rod to push the filter plate, and a spring connected to the bottom wall of the receiving hopper at the bottom of the filter plate.

[0020] By adopting the above technical solution, the rotating rod is driven by the second motor to rotate, which in turn causes the cam to rotate. This pushes the filter plate up and down, and with the help of the spring, the filter plate vibrates up and down, further improving the drying efficiency of sludge.

[0021] The beneficial effects of this utility model are:

[0022] 1. In this utility model, sludge is poured into the drying chamber through the feed inlet. By driving the electric push rods on both sides, the two extrusion plates are brought together to squeeze the sludge, expel the water, and discharge it through the drain hole for preliminary dewatering treatment. Then, the discharge port is opened by the closing part. At this time, the sludge has a certain moisture content and can be smoothly discharged from the drying chamber, making material collection more convenient.

[0023] 2. In this utility model, the rotating rod is driven by a second motor to rotate the cam, which pushes the filter plate up and down. With the help of the spring, the filter plate vibrates up and down, throwing the sludge upwards. Combined with the air dryer, the sludge can be dried more quickly and thoroughly.
