Description

Technical Field

[0001] This utility model belongs to the technical field of acoustic cleaning devices, and in particular relates to a rotary nozzle for acoustic cleaning devices. Background Technology

[0002] A sonic cleaner is a device that uses the energy of sound waves to remove accumulated dust. It typically consists of a sound generator, a control system, and other components. The working principle of a sonic cleaner is to use the energy of sound waves to remove accumulated dust. Specifically, the sonic cleaner generates sound waves of a specific frequency and intensity through the sound generator. These sound waves interact with the surface of the accumulated dust during propagation, causing the dust to vibrate and detach from the surface.

[0003] Sonic soot cleaners are widely used in various equipment in industries such as power, metallurgy, chemical, and building materials, especially in the cleaning of boilers. Boilers accumulate a lot of ash over a long period of use, so they need to be cleaned regularly. However, existing soot cleaning nozzles extend into the furnace body in a single direction, which creates many blind spots and results in poor cleaning effect. To address this, we propose a rotary nozzle for the soot cleaner to solve the above-mentioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a rotating nozzle for an acoustic cleaning device, which increases the cleaning area and reduces the cleaning blind zone, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rotary nozzle for an acoustic soot remover includes a nozzle body disposed on the top of a furnace body. The bottom of the nozzle body is connected to a cross-shaped nozzle. An electric cylinder is fixedly connected to the top of one side of the furnace body surface. A support plate is fixedly connected to the telescopic end of the electric cylinder. A stepper motor is fixedly connected to the top of the support plate. A driving bevel gear is fixedly connected to the output end of the stepper motor. A connecting pipe is rotatably supported by a bearing seat on the inner surface of the support plate. A driven bevel gear is fixedly sleeved on the surface of the connecting pipe. The surfaces of the driving bevel gear and the driven bevel gear mesh. An outer connecting pipe is rotatably connected to the top end face of the connecting pipe through a rotary joint. The connecting pipe and the nozzle body are threadedly connected. Both the connecting pipe and the nozzle body are hollow structures. A guide rod is fixedly connected to the top end face of the furnace body. The inner surface of the support plate is slidably connected to the inner surface of the guide rod.

[0006] Preferably, a one-way valve is provided on the top of the nozzle body surface.

[0007] Preferably, the top of the guide rod is fixedly connected to a limiting plate for limiting the upward sliding of the support plate.

[0008] Preferably, the top and bottom faces of the furnace body are respectively connected to an inlet pipe and an outlet pipe, the size of the nozzle is smaller than the inner diameter of the inlet pipe, and a control valve is movably connected to the ports of the inlet pipe and the outlet pipe.

[0009] Preferably, the nozzle can extend into the inner surface of the furnace body, the number of nozzles is at least four, and the nozzles are designed at an angle.

[0010] Preferably, the external connector can be connected to an acoustic wave generator via an external flexible hose.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model connects the external pipe to the external sound wave generator. The electric cylinder moves downward, causing the support plate to move the nozzle body and nozzle connected to the connecting pipe, thus extending into the interior of the furnace body. After extension, the stepper motor drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate, and then drives the connecting pipe to rotate through the bearing seat. The rotary joint facilitates the rotation of the connecting pipe without hindering the transmission of sound waves, so that the sound waves can clean the interior of the furnace body through the nozzle, generating sound waves of specific frequency and intensity. These sound waves interact with the ash surface during propagation, causing the ash to vibrate and detach from the surface. By setting the above structure, the effect of rotating and transmitting sound waves can be achieved, increasing the cleaning area and reducing the cleaning blind zone.

[0013] 2. By setting a one-way valve, this utility model can prevent dust from flowing back into the connecting pipe during cleaning;

[0014] 3. By setting a limiting plate, this utility model can limit the upward movement of the support plate and prevent derailment.

[0015] 4. This utility model has control valves movably connected to the ports of the furnace inlet pipe and the furnace outlet pipe. When cleaning the inside of the furnace, the furnace inlet pipe or the furnace outlet pipe can be opened to extend the nozzle into the furnace body, which also facilitates the flow of gas.

The external pipe 12 is connected to the external sonic generator. The electric cylinder 4 moves downward, causing the support plate 5 to move the nozzle body 2 and the nozzle 3 connected by the connecting pipe 9, thereby extending into the interior of the furnace body 1. After extension, the main motor 6 drives the main... The moving bevel gear 7 rotates, which drives the driven bevel gear 10 to rotate, and then drives the connecting pipe 9 to rotate through the bearing seat 8.

By setting the above structure, the effect of rotating and transmitting sound waves can be achieved, increasing the cleaning area and reducing the cleaning blind zone.

[0025] Example 2:

[0026] Figure 1-3This invention illustrates a rotary nozzle for an acoustic soot remover according to an embodiment of the present invention. It includes a nozzle body 2 mounted on the top of a furnace body 1.
