Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and more specifically relates to a sewage flocculation sludge drying treatment device for sewage environmental protection engineering. Background Art

[0002] Sludge is composed of solid matter in the original wastewater and solid matter generated in the wastewater treatment process. Through the treatment of sludge, the sludge is concentrated, tempered, dehydrated, stabilized, dried or incinerated to reduce, stabilize and make it harmless. Therefore, the sludge can be transformed and used in various fields, realizing the rational reuse of waste. In the process of sludge preparation and processing, the viscous sludge must first be dried to remove moisture, so as to facilitate the subsequent further operation of the sludge.

[0007] An adjusting mechanism capable of adjusting the inclination angle of the drying furnace body is installed in the base, and the adjusting mechanism comprises: a chamber provided inside the base and a rectangular groove connected to the chamber, and a screw rod rotatably installed in the chamber. A second motor is provided on the outer wall of the base, driving the output shaft of the second motor to be fixedly connected to the screw rod. A slider is threadedly connected to the screw rod, and a connecting rod is connected to the slider. One end of the connecting rod is rotatably connected to the slider, and the other end is rotatably connected to the bottom of the drying furnace body.

[0008] The advantages of this scheme are at least that: when the sludge is dried, the sludge is added into the drying furnace body through the feed port, and during the drying process, the first motor is started, which drives the stirring shaft and the stirring paddle to rotate, so that the large-volume mud blocks appearing in the sludge drying process are broken up, and after the drying is completed, when the dried sludge is poured out of the drying furnace body, the baffle plate at the discharge port is opened first, and then the second motor is started, and the second motor is started and the screw rod is driven to rotate at the same time, and the rotation of the screw rod drives the slider to move on the screw rod, and the displacement drives the connecting rod to rotate at the same time, and the rotation causes the drying furnace body to tilt at an angle on the base, so that the dried sludge can be quickly taken out of the drying furnace body, thereby improving the efficiency of taking out the dried sludge.

[0009] The utility model is further configured as follows: a base is provided below the drying furnace body, a groove is provided on the base, a support frame for further supporting the drying furnace is rotatably installed in the groove, and a telescopic component for preventing the support frame from falling off the groove is slidably fitted at the notch of the groove.

[0010] The utility model is further configured as follows: the telescopic assembly comprises: a plurality of sliding grooves and clamping grooves provided on opposite sides of the inner wall of the groove, and a sliding plate slidably matched in the sliding grooves.

[0011] The utility model is further configured as follows: a blind hole is opened on the sliding plate, a round hole is opened on the card slot, a limit pin matching the blind hole is slidably installed in the round hole, and a first spring is provided between one end of the limit pin and the bottom surface of the card slot.

[0012] The utility model is further configured as follows: a second spring is installed between the bottom surface of the groove and the support frame.

[0013] The utility model is further configured as follows: a latching tooth for preventing the support frame from slipping is arranged beside the rectangular groove, and a clamping block cooperating with the latching tooth is arranged on the support frame.

[0014] The utility model is further configured as follows: the inner bottom surface of the drying furnace body has a certain inclination angle.

[0015] The utility model is further configured as follows: a handle plate is provided on the surface of the sliding plate.

[0016] In summary, the utility model has at least the following advantages:

[0017] 1. When the sludge is dried, the sludge is added into the drying furnace body through the feed port. During the drying process, the first motor is started, and the first motor drives the stirring shaft and the stirring paddle to rotate, so that the large-volume mud blocks appearing in the sludge drying process are broken up. After the drying is completed, when the dried sludge is poured out of the drying furnace body, the baffle plate at the discharge port is opened first, and then the second motor is started. When the second motor is started, the screw rod is driven to rotate, and the rotation of the screw rod drives the slider to move on the screw rod, and the displacement drives the connecting rod to rotate. When rotating, the drying furnace body is tilted at an angle on the base, so that the dried sludge is quickly taken out of the drying furnace body, thereby improving the efficiency of taking out the dried sludge;

[0018] 2. A groove is provided under the drying furnace body, and a support frame is rotatably installed in the groove. When the drying furnace body is tilted, the support frame can be further supported. A telescopic component that slides and fits in the notch of the groove prevents the support frame from falling off the groove. A blind hole is provided on the sliding plate, and a round hole is provided on the card slot. A limit pin that fits in with the blind hole is slidably installed in the round hole. A first spring is provided between one end of the limit pin and the bottom surface of the card slot, and a second spring is installed between the bottom surface of the groove and the support frame. By providing the blind hole, the limit pin and the first spring, the phenomenon of the sliding plate moving back and forth due to the vibration of the drying furnace body is avoided.

[0019] 3. A second spring is provided between the bottom surface of the groove and the support frame, and a handle plate is provided on the surface of the sliding plate, so that when the dried sludge is taken out, the limit pin is first pressed to separate the limit pin from the blind hole, and then the sliding plate is moved to the other end by holding the handle plate with fingers to expose the support frame. At this time, under the action of the second spring, the support frame automatically pops out of the groove, and the support frame is more firmly fixed by setting the latch teeth and the latch blocks. The inclined angle of the inner bottom surface of the drying furnace body makes it easier for the dried sludge to slide out of the drying furnace body. BRIEF DESCRIPTION OF THE DRAWINGS
