Description

Technical Field

[0001] This utility model relates to the field of ovens, and more particularly to an oven with an improved combustion chamber structure. Background Technology

[0002] In existing technology, a drying oven is a device used to dehydrate wet materials using hot air or other heating methods. It is widely used in industries such as textiles, pharmaceuticals, chemicals, and food processing. Based on the heat source type, drying ovens can be classified as oil-fired, gas-fired, and steam-fired, among others. Natural gas drying ovens (also known as gas-fired ovens) convert natural gas or liquefied petroleum gas into heat energy through combustion in the combustion chamber. The heat is then blown into the air inlet by a high-temperature fan, reaching the object being dried and forming a hot air circulation, thus achieving a drying effect. Depending on the degree of moisture in the object being dried, multiple sections are generally required to achieve complete drying.

[0003] Because the burner's flame-spraying device has a large structural volume, gas-fired ovens on the market often place the burner's flame-spraying device and the circulating fan on both sides. This means that hot air needs to travel a distance the width of the frame to reach the vicinity of the circulating fan. After traveling this distance to the circulating fan, the hot air will inevitably suffer heat loss, and the suction power of the fan is relatively high. Only a fan with strong suction power can draw the hot air to the other side, resulting in problems such as low heat utilization rate and high energy consumption in the oven. Utility Model Content

[0004] This application provides an oven with an improved combustion chamber structure, which solves the problems in the prior art.

[0005] The technical solutions adopted in the embodiments of this application are as follows.

[0006] An oven with an improved combustion chamber structure includes an oven body, a drying component for drying fabric, a burner for generating heat, a heat insulation plate to prevent heat loss, and a heating chamber for retaining heat. The drying component is located on one side of the oven body and on the upper side of the oven body. The burner is located on the lower side of the oven body. Several sets of heat insulation plates are provided, and the heat insulation plates form a combustion chamber. The heating chamber is located in the combustion chamber. The burner heats the heating chamber.

[0007] As a further improvement to the above technical solution: the combustion chamber is gradually compressed towards the drying component.

[0008] As a further improvement to the above technical solution: filter screens are provided on both the left and right sides of the combustion chamber; the filter screens slide on the side walls of the combustion chamber; when the filter screens are closed, the drying unit draws air in from the filter screens.

[0009] As a further improvement to the above technical solution: a handle is provided on the filter screen; the handle facilitates opening the combustion chamber for maintenance.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] 1. Due to the improved combustion chamber structure and reduced volume, the combustion chamber and circulating fan are arranged on the same side. The combustion chamber can be located below or above the circulating fan. This allows the air heated by the combustion chamber to be directly drawn away by the circulating fan over a shorter distance. After the air is drawn away, the negative pressure area created in the combustion chamber allows air to enter the combustion chamber from both sides for heating. The circulating fan evenly sprays hot air onto the fabric through the air duct. The water vapor generated by the heat exchange between the hot air and the damp fabric is drawn away by the exhaust fan at the top, creating a continuous cycle. The oven with the improved combustion chamber structure drives the mesh belt to rotate through the transmission box, thereby moving the fabric on the mesh belt forward. Once the fabric enters the oven body, the air ducts arranged on the fabric continuously blow hot air onto the fabric surface. The hot air in the air ducts comes from the... The air heated by the burner is sent into the air duct through a circulating fan. The air duct has many small holes on the side facing the fabric, so that the hot air is blown evenly on the fabric for heat exchange. The water vapor carried away rises to the top and is drawn away by the dehumidifying fan located at the top. Thus, the layout of the circulating fan and the combustion chamber on the same side improves the thermal energy utilization rate and achieves energy saving. With the improved thermal energy utilization rate, the number of sections of the drying oven can be reduced, thereby reducing the footprint of the entire set of equipment. The combustion chamber structure has been improved, adopting an innovative design with air intake on both sides and air exhaust on the top, which meets the requirement of the circulating fan and the combustion chamber being on the same side. This significantly shortens the distance between the heat source and the circulating fan. This layout minimizes heat loss, increases the heat acting on the fabric for better drying effect, and reduces energy consumption at the same temperature, making it more energy-efficient and environmentally friendly.

[0017] This application provides an oven with an improved combustion chamber structure, which solves the problems in the prior art.

[0018] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] An oven with an improved combustion chamber structure includes an oven body 1, a drying component 2 for drying fabric, a burner 3 for generating heat, a heat insulation plate 4 to prevent heat loss, and a heating chamber 5 for retaining heat. The drying component 2 is located on one side of the oven body 1. The drying component 2 is located on the upper side of the oven body 1. The burner 3 is located on the lower side of the oven body 1. Several sets of heat insulation plates 4 are provided, and the heat insulation plates 4 form a combustion chamber 6. The heating chamber 5 is located inside the combustion chamber 6. The burner 3 heats the heating chamber 5.

[0021] The combustion chamber 6 is gradually compressed towards the drying component 2.

[0022] Filter screens 7 are provided on both the left and right sides of the combustion chamber 6; the filter screens 7 slide on the side walls of the combustion chamber 6; when the filter screens 7 are closed, the drying component 2 draws air in from the filter screens 7.

[0023] The filter screen 7 is equipped with a handle 8; the handle 8 makes it easy to open the combustion chamber 6 for maintenance.

[0024] The structure of combustion chamber 6 is improved, its volume is reduced, and combustion chamber 6 and circulating fan are arranged on the same side. Combustion chamber 6 can be located below or above the circulating fan. In this way, the air heated by combustion chamber 6 is directly drawn away by the circulating fan over a shorter distance. After the air is drawn away, the negative pressure area formed in combustion chamber 6 is filled with air from both sides for heating. The circulating fan evenly sprays the hot air onto the fabric through the air duct. The water vapor generated by the heat exchange between the hot air and the damp fabric is drawn away by the dehumidifying fan at the top, and the cycle continues. The oven with the improved structure of combustion chamber 6 is driven by a transmission box. The rotating conveyor belt moves the fabric forward. Once the fabric enters the oven, hot air is continuously blown onto its surface by air ducts arranged on it. The hot air comes from air heated by burner 3 and is sent into the ducts by a circulating fan. The ducts have many small holes on the side facing the fabric, allowing the hot air to be evenly blown onto the fabric for heat exchange. The water vapor carried away rises to the top and is drawn away by the exhaust fan located at the top. Thus, the layout of the circulating fan and combustion chamber 6 on the same side improves the thermal energy utilization rate, thereby achieving energy saving. With the improved thermal energy utilization rate, the number of sections in the oven can be reduced.

Combustion chamber 6 can be located below or above the circulating fan. This allows the air heated by combustion chamber 6 to be directly drawn away by the circulating fan over a shorter distance.

The air heated by burner 3 is sent into the air duct through a circulating fan. The air duct has many small holes on the side facing the fabric, so that the hot air is blown evenly on the fabric for heat exchange. The water vapor carried away rises to the top and is drawn away by the dehumidifying fan located at the top. Thus, the layout of the circulating fan and combustion chamber 6 on the same side improves the thermal energy utilization rate and achieves the effect of energy saving. With the improvement of thermal energy utilization, the number of sections of the drying oven can be reduced, thereby reducing the footprint of the entire set of equipment. The structure of combustion chamber 6 has been improved, adopting an innovative design with air intake on both sides and air exhaust on the top, which meets the requirement of the circulating fan and combustion chamber 6 being on the same side. This significantly shortens the distance between the heat source and the circulating fan. This layout minimizes heat loss, increases the heat acting on the fabric, and achieves better drying effect while consuming less energy at the same temperature, making it more energy-efficient and environmentally friendly.
