Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a domestic sludge drying technology. Background Art

[0002] After drying, domestic sewage sludge is transported to a dry sludge silo and then shipped out of the factory by truck. A discharge pipe is located at the bottom of the silo. Once the sludge transport vehicle aligns the vehicle compartment with the discharge pipe, it can open the silo's gate valve to discharge the sludge. In existing technology, since the silo is equipped with only one discharge pipe, the dried sludge cannot fill the entire vehicle compartment during discharge. This easily clogs the discharge pipe, impacting both discharge and the normal operation of front-end production. To address this issue, drivers are required to maneuver the vehicle forward and backward while loading the dried sludge.

[0003] With increasingly stringent environmental protection requirements, the loading and shipping of dried sludge must be carried out in a sealed room to reduce the impact of dust discharge on air quality. However, the space in a sealed room restricts the movement of vehicles, making it impossible for workers to climb onto the vehicles to manually transfer and level the dried sludge, which undoubtedly increases labor intensity and safety risks. Utility Model Content

[0004] In order to solve the above technical problems, the utility model redesigns the discharge part of the dried sludge silo and provides a discharge device that can distribute the dried sludge to the front, middle and rear sections of the carriage. The main technical solutions adopted are as follows:

[0005] A dried sludge silo discharge system includes a vertical discharge pipe, and the lower part of the vertical discharge pipe is a vehicle loading area. The key is that: the vertical discharge pipe is connected to a front guide pipe and a rear guide pipe, and the front guide pipe and the rear guide pipe are respectively inclined. The upper end of the front guide pipe is connected to the vertical discharge pipe, and the lower end of the front guide pipe extends to the front of the vertical discharge pipe. The upper end of the rear guide pipe is connected to the vertical discharge pipe, and the lower end of the rear guide pipe extends to the rear of the vertical discharge pipe.

[0006] The front guide pipe, vertical discharge pipe and rear guide pipe can respectively guide the dried sludge to the front, middle and rear of the sludge transfer vehicle, thereby preventing the dried sludge from locally gathering and clogging in the vehicle compartment and preventing the vehicle compartment from being incompletely filled with sludge.

The upper end of the front material guide pipe 2 is connected to the vertical discharge pipe 1, and the lower end of the front material guide pipe 2 extends to the front of the vertical discharge pipe 1. The upper end of the rear material guide pipe 3 is connected to the vertical discharge pipe 1, and the lower end of the rear material guide pipe 3 extends to the rear of the vertical discharge pipe 1.

[0015] Specifically, the tube wall of the vertical discharge pipe 1 is provided with a forward opening and a rearward opening, the forward opening and the rearward opening are arranged opposite each other, the forward opening faces the front of the vertical discharge pipe 1, and the rearward opening faces the rear of the vertical discharge pipe 1;

[0016] The upper end opening of the front material guiding pipe 2 is connected to the forward opening, and the upper end opening of the rear material guiding pipe 3 is connected to the rearward opening.

[0018] In order to improve the effect of directional discharge of sludge, a material drop reversing assembly is provided in the vertical discharge pipe 1. A specific embodiment of the material drop reversing assembly is:

[0019] The blanking reversing assembly includes a central rotating shaft 41, which is horizontally arranged. The front guide pipe 2 and the rear guide pipe 3 are respectively located on both sides of the central rotating shaft 41.

[0020] One end of the central rotating shaft 41 is inserted into the inner wall of the vertical discharge pipe 1, and the other end of the central rotating shaft 41 is movable through the wall of the vertical discharge pipe 1, so that the central rotating shaft 41 is rotatably assembled in the discharge pipe 1. A limit block is provided on the central rotating shaft 41 to limit its axial sliding, and a reversing handle 42 is connected to the protruding end of the central rotating shaft 41;

[0021] A reversing plate 43 is fixed to the central rotating shaft 41. The reversing plate 43 is vertically arranged and parallel to the central rotating shaft 41. The middle portion of the reversing plate 43 is connected to the central rotating shaft 41. The centerline of the discharge pipe 1 passes through the plane where the reversing plate 43 is located. The front guide pipe 2 and the rear guide pipe 3 are respectively located on both sides of the reversing plate 43.

[0022] The reversing plate 43 can rotate in both directions along with the central rotating shaft 41 within a certain angle range;

[0023] When the reversing plate 43 is kept in a vertical position, the upper end of the discharge pipe 1 is connected to its lower end. At the same time, the upper end of the discharge pipe 1 is also connected to the front guide pipe 2 and the rear guide pipe 3. Under the action of gravity, most of the dried sludge is discharged from the lower end of the discharge pipe 1.

[0024] The reversing plate 43 can be rotated until its lower edge is butted against the wall of the front guide pipe 2. At this time, the reversing plate 43 remains in a backward tilted position, and the upper end of the discharge pipe 1 is connected to the front guide pipe 2, and most of the dried sludge is discharged from the front guide pipe 2.

[0030] In order to limit the rotation angle of the reversing plate 43 to a suitable range, a forward tilting stopper 45 is provided on the inner wall of the front material guide tube 2. The forward tilting stopper 45 is used to limit the forward rotation of the upper edge of the reversing plate 43.

[0031] A backward tilting stopper 46 is provided on the inner wall of the front material guide tube 2, and the backward tilting stopper 46 is used to limit the upper edge of the reversing plate 43 from rotating backward;

[0032] The forward tilt stopper 45 and the backward tilt stopper 46 are located on both sides of the reversing plate 43 .

[0033] At the same time, in order to facilitate solving the possible sludge blockage problem, a front inspection window is opened on the wall of the front material guide pipe 2. The front inspection window is tilted upward and covered with a front window cover. One side of the front window cover is hinged to the wall of the front material guide pipe 2. The front window cover covers and closes the front inspection window by its own gravity.
