Description

Technical Field

[0001] This utility model belongs to the field of gas supply equipment technology, specifically relating to an energy-saving access device and a kiln system using it. Background Technology

[0002] In the ceramic production process, kilns are usually used to dry the ceramic tile blanks.

[0003] A kiln typically consists of a kiln body, spray guns mounted on both side walls of the kiln body, rollers arranged along the length of the kiln body, and an air supply pipeline system connected to the spray guns. Existing air supply pipeline systems generally consist of a main pipeline located at the top of the kiln body and branch pipelines located on both sides of the kiln body. These systems primarily supply combustion air. Due to the long length of the kiln, combustion air inlet fans are required at both ends of the main pipeline to deliver flame-retardant air.

[0004] Existing gas supply pipelines mainly introduce air by blowing air in through fans to achieve the input of combustion air. However, in ceramic production workshops or factories, there are a lot of dust or other particulate matter in the air. This means that the combustion air input through the gas supply pipeline contains dust, which not only increases the energy consumption of the kiln combustion, but also makes it easy for dust to fall on the tiles, which increases the dirt on the tiles and can easily lead to a decline in product quality or even failure to meet requirements. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving access device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An energy-saving access device includes at least:

[0008] The mixing chamber is equipped with a first air inlet and a first air outlet.

[0009] The filter is located at the first air inlet.

[0010] The fan is equipped with a second air inlet and a second air outlet, with the second air inlet connected to the first air outlet.

[0011] The connecting pipe has one end connected to the second air outlet and the other end connected to the main gas supply pipe.

[0012] In some implementations, the mixing chamber is also provided with a third air inlet, and the output end of the oxygen-enriched pipe is connected to the third air inlet.

[0013] In some implementations, the first air inlet consists of multiple air inlets located on the upper surface of the mixing chamber, with each air inlet corresponding to a filter.

[0014] In some implementations, air inlets are formed on the upper end and sidewalls of the filter.

[0015] In some implementations, there are two fans.

[0016] In some embodiments, the energy-saving access device further includes a first connecting pipe and a second connecting pipe, wherein the second air inlet of the fan is connected to the first end of the first connecting pipe, the second end of the first connecting pipe is connected to the first end of the second connecting pipe, and the second end of the second connecting pipe is connected to the first air outlet.

[0017] In some embodiments, the energy-saving access device further includes a first connecting pipe and a second connecting pipe, with the second air inlets of the two fans connected by the first connecting pipe, and the first end of the second connecting pipe connected to the middle of the first connecting pipe and the second end connected to the first air outlet.

[0018] To achieve the above objectives, this utility model also provides the following technical solution:

[0019] A kiln system includes a kiln, which includes a kiln body and a gas supply pipe and a spray gun disposed on the kiln body. The spray gun is connected to the gas supply pipe. The kiln also includes a gas inlet device disposed on the kiln body and connected to the gas supply pipe. The gas inlet device is the aforementioned energy-saving inlet device.

[0020] In some embodiments, the kiln system further includes an oxygen supply device and a combustible gas supply device. The outlet of the oxygen supply device is connected to a mixing chamber and configured to supply oxygen-enriched gas. The combustible gas supply device is connected to a spray gun and configured to supply combustible gas.

[0021] In some embodiments, there are two gas inlet devices, and the gas supply pipeline includes a main pipeline and branch pipelines. The main pipeline is located at the upper end of the furnace body and its two ends are respectively connected to the connecting pipes of the two gas inlet devices. The branch pipelines are located on both sides of the furnace body and are respectively connected to the spray gun and the main pipeline.

[0022] The beneficial effects of this utility model are:

[0023] 1. This utility model provides a novel access device for conveying combustion air. The device adds a mixing chamber and a filter to the traditional air supply pipeline. Before entering the main air supply pipeline, the combustion air is filtered to remove dust and other particulate matter, making the combustion air clean. This not only helps to improve combustion efficiency and achieve energy saving, but also effectively reduces dirt accumulation during the drying process and improves product quality.

[0024] 2. This device can also be connected to oxygen-enriched gas. The oxygen-enriched gas can be mixed with air in the mixing chamber to obtain combustion air with a high oxygen content, which can further improve combustion efficiency and quality, and further improve energy saving. More importantly, traditional oxygen-enriched pipelines are set up independently, and the number and route of the oxygen-enriched pipelines are the same as the gas supply pipelines. That is, the pipeline system of traditional kilns has two sets, one for air input and one for oxygen-enriched gas input. This not only occupies a lot of space but also has high costs. This device first mixes oxygen-enriched gas and air in the mixing chamber, and then uses a shared gas supply pipeline system to complete the transportation, which not only effectively saves space but also saves costs. In addition, it can simplify the traditional spray gun structure. Traditional spray guns require three air inlet chambers: ordinary combustion air, oxygen-enriched combustion air, and gas. The spray guns of the kiln system to which this device is applicable only need to have two air inlet chambers: combustion air and gas, further saving costs.

[0025] 3. This energy-saving access device and the kiln system using it have many advantages such as energy saving, low cost, and convenient maintenance. Attached Figure Description

[0039] The mixing chamber 41 is also provided with a third air inlet 412, and the output end of the oxygen-enriched pipe 45 is connected to the third air inlet 412.

[0040] The first air inlet of the mixing chamber 41 consists of multiple air inlets opened on the upper surface of the mixing chamber 41, and each air inlet is equipped with a filter 42.

[0041] Filter 42 can adopt a commonly used filter structure on the market.

[0042] Preferably, the filter 42 in this embodiment is a cylindrical filter, which can be installed on the top of the mixing chamber 41 through connecting parts such as flanges or valve seats. The filter element can be made of filter paper or nylon to form a mesh filter structure, and the filter element can be set to be detachable for easy replacement.

[0043] As a further preferred embodiment, filter elements may be provided at the upper end and side wall of filter 42 to form air inlet holes at the upper end and side wall of filter 42.

[0044] Preferably, in this embodiment, there are two fans 43.

[0045] In order to connect the fan 43 and the connecting pipe 44, the energy-saving access device in this embodiment also includes a first connecting pipe 46 and a second connecting pipe 47. The second air inlets of the two fans 43 are arranged opposite to each other, and the second air inlets of the two fans 43 are connected by the first connecting pipe 46. The first end of the second connecting pipe 47 is connected to the middle of the first connecting pipe 46, and the second end is connected to the first air outlet 411. That is, the first connecting pipe 46 and the second connecting pipe 47 in this embodiment are T-shaped.

[0046] Example 2

[0047] Please see Figure 3 As shown, this utility model provides the following technical solution:

[0048] A kiln system includes a kiln, which includes a kiln body 1, an air supply pipe 2 and a spray gun 3 disposed on the kiln body 1, the spray gun 3 being connected to the air supply pipe 2, and the kiln also includes a gas inlet device 4 disposed on the kiln body 1 and connected to the air supply pipe 2, the gas inlet device 4 being the aforementioned energy-saving inlet device.

[0049] The kiln system also includes oxygen supply equipment and combustible gas supply equipment. The outlet of the oxygen supply equipment is connected to the mixing chamber 41 and is configured to supply oxygen-enriched gas. The combustible gas supply equipment is connected to the spray gun 3 and is configured to supply combustible gas. The oxygen supply equipment can consist of an oxygen generator and an oxygen delivery pipeline, and its purpose is to prepare oxygen-enriched gas with an oxygen content of 29-30%. The purpose of the combustible gas supply equipment is to input combustible gas into the spray gun 3. Specifically, the combustible gas supply equipment can be a combination of a gas source and a pipeline, such as a combination of a natural gas source and a natural gas pipeline, or a combination of a gas cylinder and a gas pipeline.

[0050] Preferably, since the furnace body 1 is relatively long, in order to achieve a stable gas supply, two gas inlet devices 4 are provided. The gas supply pipe 2 includes a main pipe 21 and a branch pipe 22. The main pipe 21 is located at the upper end of the furnace body 1 and its two ends are respectively connected to the connecting pipes 44 of the two gas inlet devices 4.

[0051] Example 3

[0052] Please see Figure 4 As shown, this utility model provides another embodiment of the energy-saving access device.

[0053] like Figure 4 As shown, the structure of this energy-saving access device is basically the same as that of the energy-saving access device in Embodiment 1, except that the arrangement of the first connecting pipe 46 and the second connecting pipe 47 is different.

[0054] In this embodiment, the second air inlet of each fan 43 is connected to the first end of the first connecting pipe 46, the second end of the first connecting pipe 46 is connected to the first end of the second connecting pipe 47, and the second end of the second connecting pipe 47 is connected to the first air outlet 411. That is, all the first connecting pipes 46 and the second connecting pipes 47 in this embodiment are Y-shaped.

[0055] The technical solution of this utility model has at least the following advantages over the prior art:

[0056] 1. This utility model provides a brand-new access device suitable for conveying combustion air. The device adds a mixing box 41 and a filter 42 to the traditional air supply pipe 2. Before entering the main air supply pipe 21, the combustion air is filtered by the filter 42 to remove dust and other particulate matter, making the combustion air clean. This not only helps to improve combustion efficiency and achieve energy saving, but also effectively reduces dirt accumulation during the drying process and improves product quality.

[0057] 2. This device can also optionally be connected to oxygen-enriched gas. The oxygen-enriched gas can be mixed with air in the mixing chamber 41, thereby obtaining combustion air with a high oxygen content, which can further improve combustion efficiency and quality, and further improve energy-saving effect. More importantly, the traditional oxygen-enriched pipeline 45 is set up independently. The number and route of the oxygen-enriched pipeline 45 are the same as the air supply pipeline 2. That is, the traditional kiln has two sets of pipeline systems, one for inputting air and one for inputting oxygen-enriched gas. This not only occupies a lot of space but also has high cost. This device first mixes the oxygen-enriched gas and air in the mixing chamber. The mixture is mixed within body 41 and then transported using a shared gas supply pipeline system. This not only effectively saves space but also significantly reduces costs (saving the cost of a gas supply pipeline, which costs around 500,000 yuan). Furthermore, it simplifies the structure of traditional spray guns. Traditional spray guns require three air inlets or three air inlets for ordinary combustion air (air), oxygen-enriched combustion air (oxygen-enriched gas), and gas. The spray gun 3 used in the kiln system for which this device is applicable only needs two air inlets or two air inlets for combustion air and gas, further reducing costs.

[0058] 3. This energy-saving access device and the kiln system using it have many advantages such as energy saving, low cost, and convenient maintenance.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
