Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically to dust removal equipment for pusher kilns. Background Technology

[0002] Pusher kilns, as a common type of industrial kiln, are widely used in industries such as ceramics, electronics, and refractory materials. In these production processes, materials are fired along an internal track within the kiln by pushers. For example, pusher kilns play a crucial role in high-temperature firing; electrode powder is placed on the pushers and slowly pushed into the kiln body. Different temperature zones are set within the kiln, generally gradually increasing from a low-temperature preheating zone to a high-temperature firing zone, where temperatures can reach 800℃-1200℃. Under high temperatures, organic matter in ternary materials is decomposed and burned off, while some impurities also volatilize.

[0003] Dust is generated at multiple stages during the operation of a pusher kiln. When materials enter and exit the kiln, friction with the kiln opening and airflow disturbances cause some material particles to escape, forming dust. During firing, some materials may undergo decomposition, volatilization, or other chemical reactions, producing gaseous substances that condense into tiny particles during cooling, becoming part of the dust. Furthermore, under prolonged high temperatures, a small amount of refractory material inside the kiln may also detach and exist as dust within the kiln environment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a dust removal device for pusher kilns, which can effectively solve the problems in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a dust removal device for a pusher kiln, including an outer frame, an ash hopper communicating with the bottom of the outer frame, and an installation plate fixed inside the outer frame. The bottom end of the ash hopper is connected to a drop pipe, and the side wall of the ash hopper is connected to an air inlet pipe. An air bag is fixed on the side wall of the outer frame, and the top end of the air bag is connected to multiple sets of flexible hoses. Multiple sets of dust collection structures are fixed inside the installation plate. One end of each set of flexible hoses is connected to a pipe, and the bottom end of each pipe is connected to multiple sets of downward spray nozzles. The downward spray nozzles are all located at the top of the dust collection structures. Multiple sets of connection ports are opened through the installation plate, and a connecting ring is fixed at the bottom end of the connection port. The dust collection structure is fixedly connected to the connecting ring.

[0007] Furthermore, an air outlet pipe is fixed on the side wall of the outer frame. The air outlet pipe has a square structure and multiple sets of round holes inside.

[0008] Furthermore, one end of each set of hoses is connected to a solenoid valve, and one end of the air bag is connected to an external high-pressure air source.

[0009] Furthermore, the outer sidewall of the sleeve ring is provided with a threaded structure, the dust collection structure is a dust collection bag structure and a ring structure for fixing the top of the bag, and the inner sidewall of the ring is provided with a threaded structure.

[0010] Furthermore, the ash hopper is funnel-shaped, wider at the top and narrower at the bottom, and has a square internal cross-section.

[0011] Furthermore, each set of pipes has a plug fixed at its end, and the end of the pipe is fixedly connected to the top of the mounting plate through an angle bracket structure.

[0012] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0013] This invention features a multi-pipe-lower nozzle structure, allowing users to determine the appropriate number of pipes and nozzles based on the number of dust collection structures. After the dust collection structure is fixed in place, the lower nozzles can be used to spray and sweep the dust, removing any dust that is stuck or adhering to the structure with high-pressure gas, thus improving the dust removal effect for subsequent uses.

[0014] In this device, the connection structure of the sleeve ring-dust suction structure is different from the existing hook-type or bolt-type connection. In this device, the mounting plate structure with the sleeve ring can be fixed to the mounting plate by threads through its internal ring structure. First, it can improve the installation effect and speed up the installation process. Second, it can be aligned with the lower nozzle at the top through the ring, saving the debugging steps and making it easy to use directly. Attached Figure Description
