Description

Technical Field

[0001] This utility model belongs to the field of electric heater technology, specifically an explosion-proof, rapid heating modular electric heater. Background Technology

[0002] In industries such as petroleum, chemical, natural gas, and mining, production processes often involve hazardous media such as flammable and explosive gases and dust, placing extremely high demands on the explosion-proof performance of heating equipment. Simultaneously, with the increasing efficiency of industrial production, heating equipment capable of rapid heating and precise temperature control has become a necessity, as traditional electric heaters are no longer sufficient to meet the demands of complex modern industrial conditions.

[0003] Traditional electric heaters have several drawbacks. First, they lack explosion-proof performance. Some electric heaters use ordinary shells without explosion-proof design or with low explosion-proof ratings. When used in flammable and explosive environments, they can easily cause explosions if internal electric sparks or high temperatures are generated. Second, they have slow heating rates. Traditional heating elements have low energy conversion efficiency, making it impossible to achieve rapid heating, resulting in longer production cycles and increased energy consumption. Third, their structural design is unreasonable. Most are one-piece structures, making maintenance difficult and hindering the flexible adjustment of heating power and range according to different process requirements, thus affecting product quality and production safety.

[0004] Therefore, we propose an explosion-proof, rapid-heating modular electric heater. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an explosion-proof, rapid-heating modular electric heater, comprising a heater housing; a heat dissipation assembly is provided on the surface of the heater housing, and a heating mechanism is provided on the inner wall of the heater housing; a reinforcing mechanism is provided on the surface of the heater housing, and a fixing mechanism is provided on the surface of the heater housing; a protective assembly is provided on the surface of the heater housing; the heat dissipation assembly includes heat dissipation holes and heat dissipation dorsal fins, with several groups of heat dissipation holes located on one side of the heater housing surface, and the heat dissipation dorsal fins threadedly installed at one end of the heater housing; the heat dissipation holes allow heat inside the heater housing to dissipate rapidly, and due to the obstruction of the protective plate, dust is difficult to enter the interior of the heater housing, and even if dust enters, it will not reach the explosion standard; the heat dissipation dorsal fins can accelerate the cooling of the surface temperature of the heater housing, thereby effectively suppressing the high temperature inside the heater housing, and preventing heat loss from the interior of the heater housing due to excessive heat dissipation.

[0006] Preferably, the heating mechanism includes a mounting slot, a heater tube, a plug, a locking block, and a connector. The mounting slot is located on the side of the heater housing away from the heat dissipation dorsal fin. The top and bottom of the plug are fixedly installed with the locking block. Four sets of heater tubes are arranged in a ring and fixedly installed on one side of the plug. The plug and locking block are movably engaged with the heater housing through the mounting slot. The side of the plug away from the heater tube is fixedly installed with the connector. In this design, the mounting slot allows the heater tube and plug to be quickly engaged and installed inside the heater housing. The combined use of the heater tube, plug, locking block, and connector can increase heating efficiency by activating multiple sets of heater tubes simultaneously, thereby achieving a rapid temperature rise effect.

[0007] Preferably, the reinforcement mechanism includes a protective frame, a plug rod, a socket, and support legs. Two sets of protective frames are provided, movably mounted on both sides of the heater housing surface. One set of protective frames is fixedly mounted to the plug rod on the side closest to the other set, while the other set has a socket on one side. The two sets of protective frames are movably connected via the plug rod and the socket. The support legs are fixedly mounted on both sides of the bottom of the protective frame. In this design, the combined use of the protective frame, plug rod, and socket provides protection for the heater housing, preventing deformation due to external pressure. Furthermore, in the event of an explosion, the protective frame reinforces the heater housing, preventing it from being torn apart. The support legs prevent the heater housing from contacting the ground, thus preventing accelerated heat loss.

[0008] Preferably, the fixing mechanism includes a mating plate, a nut, and a stud. The mating plate is fixedly installed on the top and bottom sides of the two sets of protective frames that are close to each other. The stud is movably inserted into the two sets of mating plates respectively, and the surface of the stud is threaded with the nut. In this solution, the use of the mating plate, nut, and stud together can quickly and conveniently allow users to install the protective frame, while also ensuring the strength after installation so that the two sets of protective frames will not separate.

[0009] Preferably, the protective assembly includes protective rods and protective plates. Several sets of protective rods and plates are provided. Several sets of protective rods are horizontally fixed to the top and bottom of the inner wall of the protective frame, and several sets of protective plates are vertically fixed to the sides of the inner walls of the two sets of protective frames that are far apart from each other. In this design, the protective rods prevent foreign objects in the environment from impacting the heater housing, playing a primary protective role. When impacted, the strength of the protective frame helps protect the heater housing from damage. The protective plates provide protection to the sides of the heater housing. Simultaneously, multiple sets of protective plates can also block the heat dissipation holes, preventing excessively large openings that could lead to a large accumulation of dust inside the heater housing and cause an explosion, as both excessive and insufficient dust are unlikely to cause an explosion.

[0010] Preferably, the heater housing is made of aluminum alloy. In this design, aluminum alloy has explosion-proof properties and good thermal conductivity, which can better prevent explosions and dissipate heat, ensuring that the heater can heat at a safe temperature.

[0011] The main advantages of the invention are as follows: The design incorporates heat dissipation holes, heat dissipation fins, mounting slots, heater tubes, inserts, clips, and connectors. The heat dissipation holes allow for rapid heat dissipation from inside the heater housing. Simultaneously, the protective plate prevents dust from easily entering the heater housing, and even if dust does enter, it will not reach explosion levels. The heat dissipation fins accelerate the cooling of the heater housing surface, effectively suppressing high temperatures inside the heater housing and preventing excessive heat loss. The mounting slots allow for quick and easy installation of the heater tubes and inserts inside the heater housing. The combined use of the heater tubes, inserts, clips, and connectors enables simultaneous activation of multiple heater tubes, resulting in increased heating efficiency and rapid temperature rise.

[0012] The beneficial effects of the auxiliary invention are as follows: By setting up a protective frame, insert rod, socket, and support legs, the combined use of the protective frame, insert rod, and socket can provide protection for the heater shell, preventing the heater shell from being deformed by external pressure. At the same time, if the heater shell explodes, the protective frame can also provide reinforcement for the heater shell to prevent it from being torn apart, and the support legs can prevent the heater shell from contacting the ground, thereby accelerating heat loss.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0022] like Figures 1 to 6As shown in the embodiment of this utility model, an explosion-proof, rapid-heating modular electric heater includes a heater housing 1; a heat dissipation assembly 2 is provided on the surface of the heater housing 1, and a heating mechanism 3 is provided on the inner wall of the heater housing 1; a reinforcing mechanism 4 is provided on the surface of the heater housing 1, and a fixing mechanism 5 is provided on the surface of the heater housing 1; a protective assembly 6 is provided on the surface of the heater housing 1; the heat dissipation assembly 2 includes heat dissipation holes 21 and heat dissipation dorsal fins 22, with several groups of heat dissipation holes 21 located on one side of the surface of the heater housing 1, and the heat dissipation dorsal fins... The 22 thread is installed at one end of the heater housing 1; the heating mechanism 3 includes a mounting slot 31, a heater tube 32, a plug 33, a locking block 34, and a connector 35. The mounting slot 31 is located on the side of the heater housing 1 away from the heat dissipation dorsal fin 22. The top and bottom of the plug 33 are fixedly installed with the locking block 34. The heater tube 32 is provided in four sets, and the four sets of heater tubes 32 are fixedly installed in a ring on one side of the plug 33. The plug 33 and the locking block 34 are movably engaged with the heater housing 1 through the mounting slot 31. The side of the plug 33 away from the heater tube 32 is connected to the connector 35. 35. Fixed installation. The reinforcement mechanism 4 includes a protective frame 41, a plug rod 42, a socket 43, and a support leg 44. Two sets of protective frames 41 are provided, movably installed on both sides of the heater housing 1. One set of protective frames 41 is fixedly installed with the plug rod 42 on the side closest to the other set of protective frames 41. The other set of protective frames 41 has a socket 43 on one side. The two sets of protective frames 41 are movably connected by the plug rod 42 and the socket 43. The two sides of the bottom of the protective frame 41 are fixedly installed with the support leg 44. The fixing mechanism 5 includes a mating plate 51 and a nut. 52 and studs 53, and mating plates 51 are fixedly installed on the top and bottom sides of the two sets of protective frames 41, close to each other. The studs 53 are movably inserted into the two sets of mating plates 51 respectively. The surface of the studs 53 is threaded onto the nuts 52. The protective component 6 includes protective rods 61 and protective plates 62. Several sets of protective rods 61 and protective plates 62 are provided. Several sets of protective rods 61 are horizontally fixedly installed on the top and bottom of the inner wall of the protective frame 41. Several sets of protective plates 62 are vertically fixedly installed on the side of the inner wall of the two sets of protective frames 41 that are far apart from each other. The heater shell 1 is made of aluminum alloy.

[0023] like Figures 1 to 6As shown, the opening of the heat dissipation hole 21 allows the heat inside the heater housing 1 to dissipate quickly. Simultaneously, due to the obstruction of the protective plate 62, dust has difficulty entering the interior of the heater housing 1, and even if dust does enter, it will not reach the explosion standard. The heat dissipation dorsal fin 22 accelerates the cooling of the surface temperature of the heater housing 1, thereby effectively suppressing the high temperature inside the heater housing 1 and preventing heat loss due to excessive heat dissipation. The opening of the mounting slot 31 allows the heater tube 32 and the plug 33 to be quickly snapped into place inside the heater housing 1. The combined use of the heater tube 32, plug 33, locking block 34, and connector 35 can increase heating efficiency by simultaneously activating multiple sets of heater tubes 32, thus achieving rapid temperature rise. The combined use of the protective frame 41, plug 42, and plug hole 43 provides protection for the heater housing 1, preventing deformation caused by external pressure. Furthermore, in the event of an explosion of the heater housing 1, the protective frame... The frame 41 also reinforces the heater housing 1, preventing it from being torn apart. The support legs 44 prevent the heater housing 1 from contacting the ground, thus preventing accelerated heat loss. The combined use of the mating plate 51, nut 52, and stud 53 allows users to quickly and easily install the protective frame 41, while ensuring the strength after installation so that the two sets of protective frames 41 will not separate. The protective rod 61 prevents foreign objects in the environment from impacting the heater housing 1, playing a major protective role. When impacted, it can use the strength of the protective frame 41 to protect the heater housing 1 from damage. The protective plate 62 provides protection for the sides of the heater housing 1. At the same time, multiple sets of protective plates 62 can also block the heat dissipation holes 21, preventing the openings from being too large and causing a large amount of dust to enter the heater housing 1 and accumulate, which could lead to an explosion. Since too much or too little dust is not easy to cause an explosion, the aluminum alloy material has explosion resistance and good thermal conductivity, which can better prevent explosion and dissipate heat, ensuring that the heater can heat at a safe temperature.

[0024] Working principle: During operation, the user first places the heater housing 1 on a flat surface, then picks up the connector 35 and aligns the heater tube 32 with the mounting slot 31, inserting it into the heater housing 1. When inserted to the deepest point, the stud 53 is rotated to engage the locking block 34 with the heater housing 1, thus fixing the insertion block 33 in place. Next, the two sets of protective frames 41 are fitted onto the surface of the heater housing 1. The two sets of protective frames 41 are then aligned and inserted using the insertion rod 42 and insertion hole 43, and finally fixed with the stud 53 and nut 52 to prevent loosening. The system is then ready for use. During operation, the multiple heater tubes 32 generate powerful heat energy for rapid heating. At the same time, it will also generate a lot of heat. In order to prevent the heater from exploding due to high temperature, the heat dissipation hole 21 and the heat dissipation back fin 22 are combined to achieve the effect of passive heat dissipation, so as to suppress the heat of the heater tube 32 and prevent it from exploding. In the event of an accidental explosion, the special material of the heater shell 1 can first offset most of the impact energy. Then, the cooperation of the protective frame 41, the protective rod 61 and the protective plate 62 can prevent the heater shell 1 from deforming. At the same time, it can also strengthen the explosion resistance of the heater shell 1 and reduce the damage caused by the explosion. Since the whole is modularly designed, each component can be disassembled and assembled. Therefore, any component can be replaced as needed when it is damaged, reducing the waste of unnecessary parts.

[0025] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
