Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a municipal sludge treatment device. Background Art

[0002] A large amount of sludge is generated during the sewage treatment process. When treating this sludge, a sludge treatment device is used to perform harmless processing processes such as concentrating, conditioning, dewatering, stabilizing, drying, or incinerating the sludge. It is relatively common to directly incinerate the wet sludge after drying.

[0003] When the sludge treatment device dries the sludge, generally, a filter plate is used to filter the sewage in the sludge. As the sewage in the sludge passes through the filter plate, with the extension of the filtration time, the water content of the sludge gradually decreases. After the sewage in the sludge is discharged, the sludge enters the filter plate under its own gravity, filling the through holes on the filter plate with the sludge, thereby causing the filter plate to be blocked. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the through holes on the filter plate are filled with sludge in the prior art, thereby causing the filter plate to be blocked, and to propose a municipal sludge treatment device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a municipal sludge treatment device, including an open-top box. One side of the open-top box is provided with a discharge port, and a sealing plate is connected to the discharge port. The upper end of the open-top box is communicated with a feeding mechanism. A water-filtering plate is fixedly connected inside the open-top box. A water collection chamber is formed between the water-filtering plate and the inner bottom end of the open-top box. A discharge pipe is communicated with the water collection chamber. A pushing mechanism is connected to the open part of the open-top box. The upper end of the open-top box is communicated with a fixed box. A heater is fixedly connected inside the fixed box. An air pump is fixedly connected to the open-top box, and the outlet of the air pump is communicated with the water collection chamber through a conduit.

[0007] Preferably, the open-top box and the fixed box are of an integral structure.

[0008] Preferably, the feeding mechanism includes a cylinder. The cylinder is communicated to the upper end of the open-top box. A motor is fixedly connected to the upper end of the cylinder. The output end of the motor extends into the cylinder and is fixedly connected with a crushing member. A feeding pipe is communicated with the cylinder.

[0009] Preferably, the feeding pipe is inclined on the cylinder.

[0010] Preferably, the pushing mechanism includes a mounting plate fixedly connected to the open-top box. An electric telescopic rod is fixedly connected to the mounting plate. The telescopic end of the electric telescopic rod passes through the opening of the open-top box and is rotatably connected to a movable plate. The movable plate is slidably connected into the open-top box, and the bottom end of the movable plate contacts the upper end of the water filtering plate.

[0011] Preferably, a vibration motor is fixedly connected to the movable plate.

[0012] A municipal sludge treatment device proposed by the present utility model has the beneficial effects that:

[0013] After the pushing mechanism is activated, the sludge in the open-top box is extruded from the discharge port and then reset. After the air pump is powered on and started, gas is sent into the water collection chamber. The pressure in the water collection chamber increases, and the pressurized gas in the water collection chamber performs gas flushing on the water filtering plate, flushing the sludge in the holes of the water filtering plate, separating the sludge in the holes of the water filtering plate from the water filtering plate, keeping the water filtering plate permeable and preventing blockage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Example 1: Refer to Figures 1 - 3, A municipal sludge treatment device, including an open box 1, a discharge port is provided on one side of the open box 1, a sealing plate 2 is connected to the discharge port, a feeding mechanism 3 is connected to the upper end of the open box 1, a water filtering plate 4 is fixedly connected inside the open box 1, a water collection chamber 6 is provided between the water filtering plate 4 and the inner bottom end of the open box 1, a discharge pipe is connected to the water collection chamber 6, a pushing mechanism 5 is connected to the open part of the open box 1, a fixed box 8 is connected to the upper end of the open box 1, the open box 1 and the fixed box 8 are of an integral structure, a heater 9 is fixedly connected inside the fixed box 8, an air pump 7 is fixedly connected to the open box 1, and the outlet of the air pump 7 is connected to the water collection chamber 6 through a conduit.

[0021] Working process:

[0022] The sludge is introduced into the open box 1 through the feeding mechanism 3. The introduced sludge falls on the water filtering plate 4. The water filtering plate 4 filters out the sewage in the sludge. The filtered sewage falls into the water collection chamber 6. The sewage in the water collection chamber 6 is discharged from the discharge pipe. At the same time, after the heater 9 is started, it heats up the sludge in the open box 1, heats and dries the sludge. After the set drying time, the sealing plate 2 is removed. After the pushing mechanism 5 is started, the sludge in the open box 1 is extruded from the discharge port and then reset. After the air pump 7 is powered on and started, it sends gas into the water collection chamber 6. The pressure in the water collection chamber 6 increases. The pressurized gas in the water collection chamber 6 flushes the water filtering plate 4, flushes the sludge in the holes of the water filtering plate 4, separates the sludge in the holes of the water filtering plate 4 from the water filtering plate 4, and keeps the water filtering plate 4 permeable and not blocked.

[0023] Example 2: In Example 1, referring to Figure 2 , when the sludge is introduced into the open box 1 through the feeding mechanism 3, there are blocky sludges in the sludge, which is not convenient for drying and dewatering the sludge blocks. As another preferred embodiment of the present invention, the difference from Example 1 is that the feeding mechanism 3 includes a cylinder 31. The cylinder 31 is connected to the upper end of the open box 1. A motor 32 is fixedly connected to the upper end of the cylinder 31. The output end of the motor 32 extends into the cylinder 31 and is fixedly connected with a crushing part 33. A feeding pipe 34 is connected to the cylinder 31. The feeding pipe 34 is inclined on the cylinder 31. The sludge is introduced into the feeding pipe 34. The sludge in the feeding pipe 34 is introduced into the cylinder 31. After the motor 32 is started, it drives the crushing part 33 to rotate. After the crushing part 33 rotates, it crushes the sludge in the cylinder 31, breaks up the sludge blocks, and the broken sludge is introduced into the open box 1 to improve the sludge drying effect.

[0024] Example 3: In Example 1, when pushing the sludge in the open box 1 through the feeding mechanism 3, the adhesion between the sludge and the open box 1 is relatively strong, so it is not convenient to push the sludge to move. Referring to Figure 4, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the material pushing mechanism 5 includes a mounting plate 51, the mounting plate 51 is fixedly connected to the open-top box 1, an electric telescopic rod 52 is fixedly connected to the mounting plate 51, the telescopic end of the electric telescopic rod 52 passes through the opening of the open-top box 1 and is rotatably connected to a movable plate 53, the movable plate 53 is slidably connected into the open-top box 1, the bottom end of the movable plate 53 is in contact with the upper end of the water filtering plate 4, a vibration motor 54 is fixedly connected to the movable plate 53. When pushing the dried sludge, the electric telescopic rod 52 is started to drive the movable plate 53 to move a set distance in the direction of the discharge port and then reset. During the movement of the movable plate 53, the vibration motor 54 is powered on and started. After the vibration motor 54 is started, vibrations are generated, and the generated vibrations are transmitted to the sludge and the open-top box 1, so that a gap is generated between the sludge and the inner wall of the open-top box 1, reducing the adhesion strength between the sludge and the open-top box 1, thereby facilitating the pushing of the sludge to move.

[0025] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
