Technical Field

[0001] The utility model relates to the technical field of atmosphere multi-purpose furnaces, in particular to a precisely temperature-controlled atmosphere controllable multi-purpose furnace. Background Art

[0002] One of the key development directions of heat treatment production technology is controlled atmosphere heat treatment. In the development trend of non-oxidation heat treatment technology, controlled atmosphere heat treatment is the first choice. In the current small variety and large-scale production, especially the bright quenching, annealing, carburizing quenching, carbonitriding quenching, and gas nitrocarburizing of carbon steel and general alloy structural steel parts, controlled atmosphere is still the main means, so controlled atmosphere heat treatment is still the main component of advanced heat treatment technology;

[0003] When the existing controlled atmosphere multi-purpose furnace is performing heat treatment, the reactants inside it will produce different degrees of endothermic and exothermic phenomena during the reaction process, and the temperature also has a certain influence on the reaction rate. Most controlled atmosphere multi-purpose furnaces often perform temperature monitoring and temperature control through specific temperature measurement points, resulting in a narrow temperature measurement range and inaccurate temperature measurement, which cannot meet the needs of temperature control at different stages of the reaction process, resulting in a low product qualification rate. Therefore, we propose a controlled atmosphere multi-purpose furnace with precise temperature control. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. When the existing controlled atmosphere multi-purpose furnace is performing heat treatment, the reactants inside it will produce different degrees of heat absorption and heat release during the reaction process, and the temperature also has a certain influence on the reaction rate. Most controlled atmosphere multi-purpose furnaces often perform temperature monitoring and temperature control through specific temperature measurement points, resulting in a narrow temperature measurement range and inaccurate temperature measurement, which cannot meet the needs of temperature control at different stages in the reaction process, resulting in a low product quality qualification rate.

[0011] As a preferred solution of the utility model, a water filling port is provided at the top of the water tank, and the water filling port is connected to the inside of the water tank.

[0012] The technical effect of adopting the above further solution is: the water filling port is connected to the inside of the water tank so that the staff can add water to the inside of the water tank when the water source inside the water tank is insufficient.

[0013] As a preferred solution of the utility model, a plurality of support frames are installed equidistantly between the furnace body and the reaction furnace and inside the water storage tank, and through holes are penetrated through the outer side walls of the support frames.

[0014] The technical effect of adopting the above further solution is: the support frame can support the reactor, making the overall structure more stable, and the design of the through hole allows the water source to still flow freely and cool the reactor.

[0015] As a preferred solution of the utility model, one end of the water storage tank away from the water outlet pipe is connected to a return pipe, and the return pipe extends to the interior of the water tank and is connected to the interior of the water tank.

[0017] As a preferred solution of the utility model, a control panel is installed on the front side of the furnace body near the bottom.

When it is necessary to lower the temperature inside the reactor, the water pump can be turned on. The water pump will draw water from the water tank and send it to the water storage tank through the outlet pipe, thereby cooling the reactor, which is more convenient for controlling the temperature.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] Example 1

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: a multi-purpose furnace with controlled atmosphere and precise temperature control, comprising a furnace body 1, a water tank 2 is installed on the top of the furnace body 1, and water can be stored in the water tank 2. A water pump 201 is arranged on the inner bottom surface of the water tank 2, and the water pump 201 can extract water from the water tank 2 and send it to the water storage tank 4 through the outlet pipe 202, so that the reaction furnace 3 can be cooled down. A reaction furnace 3 is arranged inside the furnace body 1, and reactants can be reacted inside the reaction furnace 3. A water storage tank 4 is formed between the furnace body 1 and the reaction furnace 3, and water can be stored in the water storage tank 4, so that the reaction furnace 3 can be better cooled down. A reaction zone 301 is formed inside the reaction furnace 3, and a temperature sensor 302 is arranged on the inner top surface of the reaction furnace 3. The temperature sensor 302 can monitor the temperature inside the reaction furnace 3 in real time. Heating rods 303 are symmetrically arranged on the inner side wall of the reaction furnace 3, and the heating rods 303 can heat the inside of the reaction furnace 3.

[0029] Example 2

[0030] like Figure 1-4 As shown, a box door 101 is provided on the front side of the furnace body 1 near the top, and a handle 102 is installed on the front side of the box door 101 near the left side. The box door 101 is hingedly connected to the furnace body 1, and the box door 101 can be opened by the handle 102, so that the staff can directly place the reactants in the reactor 3 for heat treatment.

[0031] The output end of the water pump 201 is provided with a water outlet pipe 202, which extends to the interior of the water storage tank 4. The water outlet pipe 202 is connected to the interior of the water storage tank 4. The water outlet pipe 202 is connected to the interior of the water storage tank 4, so that after the water pump 201 is turned on, it can draw water from the water tank 2 and send it into the water storage tank 4 through the water outlet pipe 202, thereby cooling the reactor 3.

[0032] A water inlet 203 is provided at the top of the water tank 2, and the water inlet 203 is connected to the inside of the water tank 2. The water inlet 203 is connected to the inside of the water tank 2 so that the staff can add water to the inside of the water tank 2 when the water source inside the water tank 2 is insufficient.

[0033] A number of support frames 401 are installed equidistantly between the furnace body 1 and the reactor 3 and inside the water storage tank 4. Through holes 402 are penetrated through the outer walls of the support frames 401. The support frames 401 can support the reactor 3 to make the overall structure more stable. The design of the through holes 402 allows water to flow freely and cool down the reactor 3.

[0034] One end of the water storage tank 4 away from the water outlet pipe 202 is connected to a return pipe 403, which extends to the interior of the water tank 2 and is connected to the interior of the water tank 2. The return pipe 403 is connected to the interior of the water tank 2, so that when the water pump 201 draws water from the water tank 2 and sends it to the water storage tank 4 through the water outlet pipe 202, the original water in the water storage tank 4 can flow back into the water tank 2 for reuse.

[0035] A control panel 5 is installed on the front side of the furnace body 1 near the bottom.

[0036] The working process of the utility model is as follows: when using a multi-purpose controlled atmosphere furnace with precise temperature control, firstly, the temperature sensor 302 can monitor the temperature inside the reaction furnace 3 in real time. If the temperature inside the reaction furnace 3 needs to be increased, the staff only needs to turn on the heating rod 303 through the control panel 5 to increase the temperature inside the reaction furnace 3. When the temperature sensor 302 detects that the temperature reaches the set value, the heating power of the heating rod 303 is controlled to be reduced through the control panel 5 to keep the temperature inside the reaction furnace 3 unchanged. When the temperature inside the reaction furnace 3 needs to be lowered, the water pump 201 can be turned on. The water pump 201 will extract the water inside the water tank 2 and send it to the water storage tank 4 through the water outlet pipe 202, so that the reaction furnace 3 can be cooled. Compared with the existing multi-purpose controlled atmosphere furnace, it is more convenient to control the reaction temperature when it is necessary to control the reaction temperature, and the temperature can be precisely controlled, which improves the convenience and practicality of the multi-purpose controlled atmosphere furnace when changing the reaction temperature.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
