Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel kilns, in particular to a filtering smoke exhaust pipe for a tile tunnel kiln. Background Art
[0002] Tunnel kiln is a tunnel-like kiln built with refractory materials, thermal insulation materials and building materials, equipped with kiln cars and other vehicles. It is a modern continuous firing thermal equipment. Tunnel kiln is widely used in the roasting production of ceramic products, and is also used in metallurgical industries such as abrasives. When the tunnel kiln is working, the smoke generated inside is usually discharged through the exhaust pipe.
[0003] At present, when the smoke exhaust pipe on the tunnel kiln discharges smoke, the particulate matter in the smoke will also be discharged into the surrounding air, causing environmental pollution. In addition, a lot of dust will adhere to the inner wall of the smoke exhaust pipe, which is inconvenient to clean. In addition, when the smoke exhaust pipe is discharging smoke, the heat in the smoke will heat the smoke exhaust pipe, making the smoke exhaust pipe continuously in a high temperature state and very easy to be damaged. The smoke exhaust pipe is mostly fixed with multiple fasteners or directly on the shell of the tunnel kiln, which makes it inconvenient to replace. Utility Model Content
[0004] The utility model aims to provide a filtering smoke exhaust pipe for a tile tunnel kiln to solve the problems raised in the above-mentioned background technology.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-4The utility model provides a technical solution: a filtering smoke exhaust pipe for a brick tunnel kiln, comprising a main pipe 1, a filtering mechanism 3 is connected to the main pipe 1 through a connecting mechanism 2; the filtering mechanism 3 comprises two fixed covers 31, the two fixed covers 31 are of the same size and form a spherical structure, the lower ends of the two fixed covers 31 are fixedly connected with plug plates 32, the two plug plates 32 are of the same size and form a tubular structure, the two plug plates 32 are plugged into the inside of the main pipe 1, the middle side walls of the two fixed covers 31 away from each other are penetrated and fixedly connected with a fixed pipe 33, and the ends of the two fixed pipes 33 away from the fixed cover 31 on the same side are fixedly connected with a filter screen 34; the connecting mechanism 2 comprises a fixing ring 21, which is sleeved and fixedly connected to the outer wall of the upper end of the main pipe 1. The middle outer walls of the front and rear sides of the fixing ring 21 are fixedly connected with a vertical plate 23 through a connecting block 22. The upper ends of the two vertical plates 23 close to each other are provided with a clamping groove 24. A sealing ring 25 is provided between the two vertical plates 23. The sealing ring 25 is clamped at the junction of the two fixing covers 31. The middle outer walls of the front and rear sides of the sealing ring 25 are fixedly connected with a clamping block 26. The clamping block 26 is clamped in the clamping groove 24 on the vertical plate 23 on the same side. When in use, the filtering mechanism 3 is fixed to the main pipe 1 through the connecting mechanism 2, so as to facilitate filtering of the exhausted smoke and reduce pollution to the surrounding environment.
[0019] The lower end of the sealing ring 25 abuts against the upper end of the main pipe 1, and the inner wall of the sealing ring 25 abuts against the outer wall of the junction of the two fixed covers 31 to ensure the sealing between the two fixed covers 31. The width of the two clamping blocks 26 is the same as the width of the clamping groove 24, and the thickness of the two clamping blocks 26 is the same as the depth of the clamping groove 24, which is convenient for fixing the sealing ring 25 between the two vertical plates 23. The length of the two plug-in plates 32 is the same as the internal height of the main pipe 1, and the outer walls of the two plug-in plates 32 are in contact with the inner wall of the main pipe 1 to prevent smoke from infiltrating between the two plug-in plates 32 and the main pipe 1. The upper ends of the two vertical plates 23 are plugged with fixing pins 27, and the lower ends of the two fixing pins 27 are inserted into the inside of the clamping blocks 26 on the same side, which is convenient for fixing the two clamping blocks 26 in the clamping groove 24 and fixing the sealing ring 25 on the two vertical plates 23.
[0020] Specifically, when the utility model is used, the main pipe 1 is fixed on the tunnel kiln. When the smoke enters the inside of the main pipe 1, the smoke will enter the inside of the two fixed covers 31 through the tubular lining composed of the two plug plates 32, and then be discharged through the two fixed pipes 33. In this process, the filter screen 34 arranged in the two fixed pipes 33 will filter out most of the dust in the smoke, reducing the pollution of the smoke to the surrounding environment. At the same time, the two plug plates 32 will isolate the heat in the smoke, preventing the main pipe 1 from being damaged due to continuous high temperature, and when cleaning and replacing the filter mechanism 3 later, unplugging Use two fixing pins 27 to push the sealing ring 25 horizontally, remove the sealing ring 25 from between the two vertical plates 23, then remove the two fixing covers 31 together with the two plug plates 32 from the main pipe 1, clean the dust attached inside, and replace them if damaged. When installing, put the two fixing covers 31 together, insert the two plug plates 32 into the inside of the main pipe 1, put the sealing ring 25 on the joint of the two fixing covers 31 to avoid air leakage, and at the same time, clamp the two clamping blocks 26 in the clamping grooves 24 on the vertical plates 23 on the same side, and fix them with the fixing pins 27.
