Description

Technical Field

[0001] This utility model relates to the field of sludge treatment equipment, and specifically to a sludge spraying device. Background Technology

[0002] Wet sludge needs to be broken up and incinerated in a boiler. The sludge injection device is a device that atomizes the sludge and injects it into the furnace for combustion through a pumping system and the high pressure of compressed air.

[0003] Chinese utility model patent CN214840874U discloses a sludge spraying device. This device includes a gun body and an internal diffuser tube. The gun body is cylindrical and fitted onto the internal diffuser tube. The gun body has a sludge inlet, and the internal diffuser tube has an inlet for spraying a dispersing medium. The internal diffuser tube slides on the gun body, and a push rod is rotatably connected to one end of the internal diffuser tube near the spray dispersing medium inlet. A positioning block is threaded onto the push rod, and the positioning block is fixed to the gun body. The position of the internal diffuser tube is adjusted by rotating the push rod with a handwheel, thereby adjusting the sludge dispersion effect. However, in actual use, it was found that simply adjusting the position of the internal diffuser tube does not achieve a good sludge dispersion effect, and manually adjusting the position of the internal diffuser tube is inefficient, has limited precision, and cannot guarantee the stability of the sludge dispersion effect.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem in existing technologies where simply adjusting the position of the internal diffuser tube fails to achieve a good dispersion effect, this utility model provides a sludge spraying device. The sludge spraying device includes: a mounting cylinder; a diffuser tube installed inside the mounting cylinder, and the diffuser tube is connected to a push cylinder that drives the diffuser tube to slide within the mounting cylinder; a mixing tube fixedly connected to the mounting cylinder, and the mixing tube communicates with a sludge spraying tube, with a sealing soft cover provided at the connection between the mixing tube and the sludge spraying tube; and an angle adjustment structure including a mounting bracket mounted on the mixing tube, a guide seat mounted on the sludge spraying tube, an adjustment seat slidably connected to the guide seat, and a screw that drives the adjustment seat to move; the mounting bracket is hinged to the sludge spraying tube, and the adjustment seat is configured to slide along the direction of the screw and lift or pull down the sludge spraying tube.

[0006] This utility model discloses a sludge injection structure, comprising an installation cylinder, a diffuser pipe, a sludge injection pipe, a mixing pipe, and an angle adjustment structure. The installation cylinder allows the diffuser pipe to slide and adjust, the diffuser pipe delivers compressed air, the sludge injection pipe delivers sludge, the mixing pipe provides a mixing space for the compressed air and sludge, and the installation angle adjustment structure is also included. The diffuser pipe is connected to a push cylinder, which slides within the installation cylinder under the drive of the push cylinder. The angle adjustment structure includes an installation frame, a guide seat, an adjustment seat, and a lead screw; the installation frame is mounted on the mixing pipe and forms a hinged connection with the sludge injection pipe, facilitating angle adjustment of the sludge injection pipe; the lead screw is connected to the adjustment seat, and the guide seat is mounted on the sludge injection pipe. When the adjustment seat moves, it lifts or pulls down the guide seat and one end of the sludge injection pipe connected to the guide seat, thereby changing the tilt angle of the sludge injection pipe. With the above-mentioned configuration, the length of the diffuser tube extending into the mixing tube is adjusted by the push cylinder in the sludge spraying device of this utility model, and the tilt angle of the sludge spraying tube is adjusted by the angle adjustment structure. Thus, under different working conditions, such as different humidity of sludge, spray volume, spray intensity, and air volume and intensity of compressed air, the compressed air and sludge can achieve a better mixing effect.

[0007] Furthermore, a guide post is provided on the adjusting seat, and a guide groove matching the guide post is provided on the guide seat.

[0008] Furthermore, there are two guide seats, which are arranged on opposite sides of the adjusting seat.

[0009] Furthermore, two mounting brackets are provided, and the two mounting brackets are located on opposite sides of the sludge injection pipe.

[0010] Furthermore, an installation platform is provided on the mixing pipe, the lead screw is installed on the installation platform, and the mounting bracket is installed on both sides of the installation platform.

[0011] Furthermore, a packing seal structure is arranged inside the mounting cylinder, and the mounting cylinder and the diffuser tube form a slidable sealed connection through the packing seal structure.

[0012] Furthermore, a support base matching the diffuser tube is provided inside the mounting cylinder; a limiting strip is formed on the support base, and a limiting groove matching the limiting strip is arranged on the diffuser tube.

[0013] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0014] By pushing the cylinder to adjust the length of the diffuser tube extending into the mixing tube, and by adjusting the angle of the sludge injection tube through the angle adjustment structure, the compressed air and sludge can achieve a better mixing effect under different working conditions, such as different sludge humidity, injection volume, injection intensity, and compressed air volume and intensity.
