Description

Technical Field

[0001] This utility model relates to the field of industrial drying equipment technology, specifically to a drying oven. Background Technology

[0002] Currently, in the industrial drying field, equipment based on the principle of electrothermal drying is widely used. These devices primarily use electric heating elements to generate heat to heat and dry materials. In many production scenarios, such as chemical production, food processing, and pharmaceutical industries, electrothermal drying equipment has become a commonly used choice due to its relatively simple principle and operation, especially when dealing with materials containing alcohol.

[0003] Although traditional electric heating drying equipment can meet basic drying needs to a certain extent, some problems have been exposed in practical applications, as follows:

[0004] The drying efficiency is low. The way the electric heating element directly generates heat limits the heating speed, making it difficult to bring the material to a suitable drying temperature in a short time. Moreover, it is difficult to achieve a uniform temperature distribution on the material throughout the drying process, which prolongs the drying time, affects the drying effect, and thus reduces product quality.

[0005] High energy consumption; when the electric heating element is working, a large amount of heat energy is lost into the surrounding air, resulting in unnecessary energy waste. Furthermore, since such equipment usually needs to operate continuously for a long time, the accumulated energy cost is considerable, which increases the production cost of enterprises and reduces the market competitiveness of products.

[0006] Therefore, how to solve the shortcomings of the existing technology, such as low drying efficiency and high energy consumption, has become the research topic to be addressed by this utility model. Utility Model Content

[0007] The purpose of this invention is to provide an oven.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An oven, comprising:

[0010] A cabinet having a receiving cavity, the cabinet serving as a component for holding items to be dried;

[0011] A water-heating assembly serves as a mechanism for drying items placed inside the receiving cavity;

[0012] The water heating component includes a water pump, water pipes, and radiators connected in sequence.

[0013] The water pump serves as a component for supplying hot water to the water pipe;

[0014] The water pipe serves as a component for transferring hot water input by the water pump to the radiator and for outputting water from the radiator; the housing is provided with a vent hole for the water pipe to pass through, and there is a ventilation area between the wall of the vent hole and the outer wall of the water pipe for air circulation.

[0015] The radiator is attached to at least a portion of the inner wall of the box; the radiator serves as a component for drying the items to be dried inside the box by transferring heat.

[0016] In the above scheme, before drying, the items to be dried are placed in the receiving cavity; during the drying process, the water pump delivers hot water into the water pipe, and the water pipe transfers the hot water input by the water pump to the radiator and outputs the water in the radiator, realizing water circulation. The circulating water carries heat to the radiator, and the water whose temperature drops after the heat is dissipated is output again, and then the water pump delivers new hot water, thereby maintaining the temperature environment required for drying.

[0017] The water heating component uses water heating technology to replace the traditional electric drying technology. The water pipes and radiators are arranged around the perimeter of the cavity. This arrangement, combined with water circulation heating, achieves a high-temperature and uniform drying effect, ensuring drying quality.

[0018] Because water has a large specific heat capacity, it can retain heat for a long time, which reduces energy consumption compared to traditional drying methods. This not only achieves the goal of energy conservation and emission reduction, but also reduces the company's operating costs and safety hazards.

[0019] Water-based heating components generate heat from hot water and transfer it directly through radiators. Compared to electric drying technology, the heating speed is relatively faster, improving drying efficiency and effectively reducing production cycle and costs by shortening drying time.

[0020] A further technical solution is that the housing includes an inner assembly layer, a first heat insulation layer, and an outer assembly layer, which are sequentially nested from the inside out.

[0021] The inner space of the assembled inner layer constitutes the receiving cavity;

[0022] The vent hole passes through the inner assembly layer, the heat insulation layer, and the outer assembly layer;

[0023] The radiator is attached to at least a portion of the inner sidewall of the assembled inner layer.

[0024] Optionally, the first insulation layer may be filled with rock wool or other equivalent materials.

[0025] The enclosure is divided into three layers from the inside out to ensure heat insulation and heat preservation.

[0026] The three-layer design of the oven not only effectively reduces heat loss inside the oven, thus improving thermal efficiency, but also enhances the oven's fire resistance. Even if an external fire source enters, it can maintain the integrity of the internal structure of the oven to prevent the spread of fire, effectively eliminating safety hazards during the drying process, improving production safety, and protecting the lives of operators.

[0027] Optionally, the inner layer, the first insulation layer, and the outer layer are all integrated into one unit to further ensure the heat insulation and heat preservation effect.

[0028] Optionally, the inner layer, the first insulation layer, and the outer layer are all assembled separately. Taking the outer layer as an example, the outer layer is assembled from a top structure, a middle structure, and a bottom structure. The middle structure can be selectively assembled from four side structures to reduce maintenance costs.

[0029] It should be noted that the three-layer design of the chamber provides comprehensive insulation and heat protection. Each layer fully or nearly fully covers the cavity, preventing heat loss from the top or bottom of the chamber. The treatment of the top of the chamber also enhances its protective effect, while the treatment of the bottom of the chamber enhances its load-bearing capacity to ensure the stability of the oven during operation.

[0030] A further technical solution is that the side of the box is provided with a discharge port, through which the inner assembly layer, the heat insulation layer and the outer assembly layer pass;

[0031] The box also includes a sealing cover, which is rotatably disposed on the outer side of the box and used to seal the discharge port opening;

[0032] The sealing cap has a second heat insulation layer inside.

[0033] The second insulation layer ensures that the heat inside the cavity is not lost in large quantities when the sealing cover is opened. The structure also has a certain fire resistance, ensuring that the fire source can be quickly shut off and isolated in an emergency.

[0034] In a further technical solution, the water pipe includes a water supply sub-pipe and a water outlet sub-pipe, wherein the water supply sub-pipe is connected to the water pump;

[0035] The ventilation holes are configured to be two;

[0036] The heating radiator is configured to be at least two, each of which has a water inlet and a water outlet. The water inlet is connected to the water supply subpipe, and the water outlet is connected to the water outlet subpipe.

[0037] Two vent holes are installed in each of the water supply sub-pipes and the water outlet sub-pipes. The vent holes serve as both the inlet and outlet of the water supply sub-pipes and as air vents, thus avoiding any impact on drying quality due to the separate opening of vent holes.

[0038] The radiators are configured with at least two flexibly adjustable radiator distribution ranges to improve drying efficiency when radiator size is limited.

[0039] The radiators are connected in parallel so that they do not affect each other, thus avoiding the inability to carry out the drying process due to the failure of a single radiator.

[0040] In a further technical solution, the height of the radiator is less than the height of the receiving cavity;

[0041] The distance between the radiator and the top wall of the cavity is greater than the distance between the radiator and the bottom wall of the cavity.

[0042] This case demonstrates how restricting the height and placement of radiators can reduce the cost of using radiators while ensuring their heating effect.

[0043] Further technical solutions also include explosion-proof components, which are installed on the housing as a component used to prevent explosions by promoting air circulation during the drying process.

[0044] When the items to be dried contain flammable and explosive materials such as alcohol (e.g., sand containing alcohol), if the drying oven generates high temperatures and sparks during operation, it may cause safety accidents such as fires or explosions.

[0045] By incorporating explosion-proof components, the oven promotes air circulation during operation, thereby reducing the temperature inside the drying chamber while controlling the alcohol concentration. This ensures that the alcohol concentration inside the chamber does not reach the threshold required for explosion (e.g., 3%), thus preventing safety accidents such as fires or explosions caused by sparks or high temperatures. This effectively eliminates safety hazards during the drying process, improves production safety, and protects the lives of operators.

[0046] In a further technical solution, the explosion-proof component is configured as an explosion-proof fan, which is located at the top center of the enclosure.

[0047] Placing the explosion-proof fan at the top of the enclosure can increase its effective range.

[0048] It should be further emphasized that, taking explosion-proof fans as an example, explosion-proof fans enable this application to be widely used in industrial fields that require drying special materials such as alcohol.

[0049] In a further technical solution, the box is configured as a rectangular prism;

[0050] Of the four inner walls of the housing, at least three inner walls are attached to the radiator. The term "attached" means both close to and tightly against the radiator.

[0051] The box is designed as a square shape to ensure sufficient space for the cavity.

[0052] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0053] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0054] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0055] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0056] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0057] The working principle and advantages of this utility model are as follows: Before drying, the items to be dried are placed in the receiving cavity; during the drying process, a water pump supplies hot water to the water pipes, which then transfer the hot water from the pump to the radiators and output the water from the radiators, thus achieving water circulation. The circulating water carries heat to the radiators, and the water that cools down after the heat dissipates is output again, and the water pump then supplies new hot water, thereby maintaining the temperature environment required for drying. The water-heated component uses water-heated heating technology to replace the traditional electric heating drying technology. The water pipes and radiators are arranged along the circumference of the receiving cavity. This arrangement, combined with water circulation heating, achieves a high-temperature and uniform drying effect, ensuring drying quality. Because water, as a medium, has a large specific heat capacity, it can retain heat for a long time, reducing energy consumption compared to traditional drying methods. This not only achieves the goal of energy conservation and emission reduction but also reduces the operating costs of enterprises and reduces safety hazards. The water-heated component generates heat from hot water and directly transfers heat through the radiators. The heating speed is relatively faster than electric heating drying technology, improving drying efficiency and effectively reducing production cycle and costs by shortening drying time.

[0064] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0065] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0066] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0067] See Figures 1-5 An oven, comprising:

[0068] The box body 1 has a receiving cavity 11, and the box body 1 serves as a component for receiving items to be dried;

[0069] Water heating component 2 serves as a mechanism for drying items placed in the receiving cavity 11;

[0070] The water heating component 2 includes a water pump (not shown in the figure), a water pipe 21 and a radiator 22 connected in sequence.

[0071] The water pump serves as a component for supplying hot water to the water pipe 21;

[0072] The water pipe 21 serves as a component for transferring hot water input by the water pump to the radiator 22 and for outputting water from the radiator 22; the housing 1 is provided with a vent hole 12 through which the water pipe 21 passes, and there is a ventilation area (i.e., the area in the vent hole 12 not filled by the water pipe 21) between the hole wall of the vent hole 12 and the outer wall of the water pipe 21 for air circulation.

[0073] The radiator 22 is attached to at least a portion of the inner wall of the box 1; the radiator 22 serves as a component for drying the items to be dried inside the box 1 by transferring heat.

[0074] Before drying, the items to be dried are placed in the receiving cavity 11. During the drying process, the water pump supplies hot water to the water pipe 21. The water pipe 21 transfers the hot water input by the water pump to the radiator 22 and outputs the water in the radiator 22, realizing water circulation. The circulating water carries heat to the radiator 22. After the heat is dissipated, the water with a lower temperature is output again, and then the water pump delivers new hot water, thereby maintaining the temperature environment required for drying.

[0075] Optionally, the water pump can be installed inside or connected to the existing mold temperature controller.

[0076] The water heating component 2 uses water heating technology to replace the traditional electric drying technology. The water pipes 21 and the radiators 22 are arranged around the circumference of the cavity 11. This arrangement, combined with water circulation heating, achieves a high-temperature and uniform drying effect, ensuring the drying quality.

[0077] Because water has a large specific heat capacity, it can retain heat for a long time, which reduces energy consumption compared to traditional drying methods. This not only achieves the goal of energy conservation and emission reduction, but also reduces the company's operating costs and safety hazards.

[0078] The water heating component 2 generates heat from hot water and transfers the heat directly through the radiator 22. The heating speed is relatively faster compared to electric drying technology, which improves drying efficiency and effectively reduces production cycle and cost by shortening drying time.

[0079] Optionally, the outer shell of the enclosure 1 is made of stainless steel.

[0080] It should be noted that, taking the water heating component 2 as an example, the water heating component 2 can be disassembled separately, which is convenient for cleaning and maintenance, and reduces maintenance costs and time.

[0081] It should also be noted that this application may include an intelligent control system. By introducing intelligent control technology, it monitors parameters such as water medium temperature and humidity in real time during the drying process and automatically adjusts drying parameters according to preset conditions to achieve the best drying effect. Simultaneously, it includes safety warning and automatic shutdown functions to ensure the safety and reliability of the drying process. The intelligent control system can improve drying effect, enhance the intelligence level of the equipment, and improve product quality. Optionally, the intelligent control system may be configured as a mold temperature controller.

[0082] It should also be noted that the radiator 22 is a component used to dry the items to be dried inside the box 1 by transferring heat. More specifically, the radiator 22 transfers heat to the receiving cavity 11, causing the receiving cavity 11 to heat up and thus achieving the drying process of the items to be dried.

[0083] It should be emphasized that, regarding the point about the radiator 22 being attached to the inner wall of the housing 1, the radiator 22 may have an installation part. The installation part is small in size and is installed by attaching the installation part to the inner wall of the housing 1. When the distance between the radiator 22 and the inner wall of the housing 1 is small, it can also be considered as the two being attached. The above description of attachment is mainly to illustrate the position of the radiator 22.

[0084] In practice, compared with electric heating drying technology (or blower electric heating drying technology), the drying efficiency of this application is increased from 2Kg / hour to 12Kg / hour, an increase of 500%, while the energy consumption is reduced by about 20%.

[0085] See Figures 1-3 In this embodiment, the housing 1 includes an inner assembly layer 13, a first heat insulation layer 14, and an outer assembly layer 15, which are sequentially arranged from the inside to the outside.

[0086] The inner space of the assembled inner layer 13 constitutes the receiving cavity 11;

[0087] The vent 12 passes through the inner assembly layer 13, the heat insulation layer, and the outer assembly layer 15;

[0088] The radiator 22 is attached to at least a portion of the inner sidewall of the assembled inner layer 13.

[0089] Optionally, the first insulation layer 14 is filled with rock wool or other equivalent materials.

[0090] Optionally, the first insulation layer 14 is provided with a support frame 18, and other areas of the first insulation layer 14 are filled with rock wool or other equivalent materials.

[0091] The enclosure 1 is divided into three layers from the inside out to ensure heat insulation and heat preservation.

[0092] The three-layer design of the chamber 1 not only effectively reduces heat loss inside the oven, thereby improving thermal efficiency, but also enhances the fire resistance of the oven. Even if an external fire source enters, it can maintain the integrity of the internal structure of the chamber 1 to prevent the spread of fire, effectively eliminating safety hazards in the drying process, improving production safety, and protecting the lives of operators.

[0093] Optionally, the inner layer 13, the first insulation layer 14, and the outer layer 15 are all integrated to further ensure the heat insulation and heat preservation effect.

[0094] Optionally, the inner layer 13, the first heat insulation layer 14, and the outer layer 15 are all separately configured. Taking the outer layer 15 as an example, the outer layer 15 is composed of a top structure, a middle structure, and a bottom structure. The middle structure can be selectively composed of four side structures to achieve the purpose of reducing maintenance costs.

[0095] It should be noted that the three-layer design of the chamber 1 is for comprehensive heat insulation and heat preservation. Each layer fully or nearly fully covers the cavity 11, preventing heat loss from the top or bottom of the chamber 1. The treatment of the top of the chamber 1 also enhances the protection effect at the top of the chamber 1, and the treatment of the bottom of the chamber 1 also enhances the load-bearing capacity at the bottom of the chamber 1 to ensure the stability of the oven during operation.

[0096] See Figure 1 In this embodiment, the side of the box 1 is provided with a discharge port 16, through which the inner assembly layer 13, the heat insulation layer and the outer assembly layer 15 pass;

[0097] The box body 1 also includes a sealing cover 17, which is rotatably disposed on the outer side of the box body 1 and is used to block the opening of the discharge port 16;

[0098] The sealing cap 17 has a second heat insulation layer inside (not shown in the figure).

[0099] The setting of the discharge port 16 should be known to those skilled in the art even if it is not explicitly stated.

[0100] The discharge port 16 passes through the box body 1 and is located on the side of the box body 1.

[0101] The sealing cover 17 is rotatably connected to the side wall of the box 1 and can be rotated into the outer area of ​​the box 1.

[0102] The shape and size of the sealing cover 17 are compatible with the shape and size of the discharge port 16.

[0103] The materials and other settings of the second insulation layer are the same as those of the first insulation layer 14.

[0104] The second insulation layer ensures that the heat inside the cavity 11 will not be lost in large quantities when the sealing cover 17 is opened. The structure also has a certain fire resistance, ensuring that the fire source can be quickly shut off and isolated in an emergency.

[0105] See Figure 2 , Figure 4 In this embodiment, the water pipe 21 includes a water supply sub-pipe 211 and a water outlet sub-pipe 212, and the water supply sub-pipe 211 is connected to the water pump;

[0106] The ventilation hole 12 is provided in two parts;

[0107] The radiator 22 is configured to be at least two, and each radiator 22 has a water inlet 221 and a water outlet 222. The water inlet 221 is connected to the water supply sub-pipe 211, and the water outlet 222 is connected to the water outlet sub-pipe 212.

[0108] Two ventilation holes 12 are provided through each of the water supply sub-pipe 211 and the water outlet sub-pipe 212. The ventilation holes 12 serve as both the inlet and outlet of the water supply sub-pipe 211 and the water outlet sub-pipe 212 and as ventilation ports, thus avoiding the impact on drying quality due to separate ventilation ports.

[0109] The radiator 22 is configured with at least two flexibly adjustable distribution ranges to improve the drying effect when the size of the radiator 22 is limited.

[0110] Each radiator 22 is connected in parallel so that it does not affect the others, thus avoiding the inability to carry out the drying process due to the failure of a single radiator 22.

[0111] Taking the connection between the water inlet 221 and the water supply sub-pipe 211 as an example, a pipe can be installed between the two.

[0112] Optionally, the water supply sub-pipe 211 is located below the water outlet sub-pipe 212.

[0113] In this embodiment, the height of the radiator 22 is less than the height of the receiving cavity 11;

[0114] The distance between the radiator 22 and the top wall of the cavity 11 is greater than the distance between the radiator 22 and the bottom wall of the cavity 11.

[0115] Optionally, the height of the radiator 22 is less than half the height of the receiving cavity 11.

[0116] Optionally, the distance between the radiator 22 and the top wall of the receiving cavity 11 is greater than twice the distance between the radiator 22 and the bottom wall of the receiving cavity 11.

[0117] This embodiment restricts the height and placement of the radiator 22, reducing the cost of using the radiator 22 while ensuring its heating effect.

[0118] It should be noted that the space occupied by the items to be dried in the receiving cavity 11 is limited; in the vertical direction, the radiator 22 in this application can be regarded as occupying the middle area, the lower middle area and part of the upper middle area of ​​the receiving cavity 11; in other embodiments, the height and placement position of the radiator 22 can be adjusted.

[0119] See Figure 1 In this embodiment, an explosion-proof component 3 is also included, which is disposed on the housing 1 as a component used to prevent explosion accidents by promoting air circulation during the drying process.

[0120] When the items to be dried contain flammable and explosive materials such as alcohol (the following explanation uses alcohol as an example), if the drying oven generates high temperatures and sparks during operation, it may cause safety accidents such as fires or explosions.

[0121] By installing the explosion-proof component 3, during the operation of the oven, the explosion-proof component 3 promotes air circulation, thereby reducing the temperature inside the containment cavity 11 and controlling the alcohol concentration inside the containment cavity 11. This ensures that the alcohol concentration inside the containment cavity 11 does not reach the threshold required for explosion (such as 3%), thus preventing safety accidents such as fires or explosions caused by sparks or high temperatures. This effectively eliminates safety hazards during the drying process, improves production safety, and protects the lives of operators.

[0122] In this embodiment, the explosion-proof component 3 is configured as an explosion-proof fan, which is located at the top center of the housing 1.

[0123] In other embodiments, the explosion-proof component 3 may be disposed on the side of the housing 1.

[0124] The explosion-proof fan is located at the top of the enclosure 1, which can increase the effective range of the explosion-proof fan.

[0125] The enclosure 1 can be equipped with a mounting port for the explosion-proof fan, and the part of the explosion-proof fan (such as the base) is locked into the mounting port.

[0126] It should be further emphasized that, taking explosion-proof fans as an example, explosion-proof fans enable this application to be widely used in industrial fields that require drying special materials such as alcohol.

[0127] See Figures 1-4 In this embodiment, the box 1 is configured as a square.

[0128] Of the four inner sidewalls of the housing 1, at least three inner sidewalls are attached to the radiator 22.

[0129] The box 1 is designed as a square shape to ensure the space for the cavity 11.

[0130] Optionally, three of the four inner walls of the housing 1 are attached to the radiator 22, and the other inner wall is provided with a discharge hole.

[0131] Optionally, all four inner walls of the housing 1 are attached to the radiator 22, and the areas on each inner wall that are attached to the radiator 22 may differ.

[0132] Optionally, radiator 22 can be configured as three.

[0133] It should be emphasized that a baffle can be installed inside the box 1, and there is an accommodating space between the inner wall of the box 1 and the baffle. The radiator 22 is placed in the accommodating space, which improves the internal aesthetics of this application. At the same time, no heat insulation layer is installed inside the baffle to avoid affecting the drying effect.

[0134] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
