The second heating component is provided with a guiding wall on one side of the flame spraying end of the burner, and a plurality of waste gas introduction holes are formed on the guiding wall.

[0008] Preferably, a front section, a middle section and a rear section are arranged along the axial direction of the flared structure, and the diameter of the waste gas introduction holes in the middle section is larger than that in the front section and the rear section.
[0009] Preferably, the length of the guiding wall is greater than the spraying length of the flame, and the length of the front-back distribution of the plurality of waste gas introduction holes on the guiding wall is greater than the spraying length of the flame.
[0010] Preferably, the shape of the waste gas introduction holes is a round hole or a rectangular hole; and / or, the waste gas introduction holes are arranged in a honeycomb shape.
[0011] Preferably, the first waste gas conveying pipeline is provided with a waste gas flow detector for detecting the waste gas flow in real time, and the second heating component is provided with a second heating controller.

[0012] Preferably, the second heating component further includes a hot gas storage cavity connected to the guiding wall, and the hot gas storage cavity is connected with a heat conveying pipeline, and the heat conveying pipeline is communicated with the internal space of the second oven body.
[0013] Preferably, the second heating component includes a waste gas introduction cavity arranged circumferentially around the guiding wall, the waste gas introduction cavity is provided with a waste gas inlet, the waste gas inlet is connected with the first waste gas conveying pipeline, and the first waste gas conveying pipeline is connected with a blower.
[0014] Preferably, the second oven is arranged below the first oven, the first waste gas discharge port is arranged at the top of the first oven, the second heating component is arranged above the first oven, and a heat conveying pipeline is arranged between the second heating component and the second oven body.
[0015] The utility model adopts the above technical solution and has the following beneficial effects:
[0016] 1. The first heating component adopts a conventional burner structure. Compared with a conventional burner, the second heating component is provided with a guiding wall on one side of the flame spraying end of the burner, and a plurality of waste gas introduction holes are formed on the guiding wall. During the operation of the second heating component, air is introduced from the air inlet end. The waste gas introduction holes are arranged on one side of the flame spraying end. The combustion process of air and gas entering the burner is the same as that of a conventional burner, and the burner can burn normally. The flame sprayed after combustion contacts the waste gas and ignites the waste gas. In this way, the air flow rate and velocity generated by introducing waste gas from the waste gas introduction holes hardly affect the normal combustion of the burner, and there is no need to accurately control the flow rate and velocity of the waste gas, avoiding the waste gas airflow from blowing out the burner flame.
[0017] The waste gas introduction holes are connected to the first waste gas discharge port through a first waste gas delivery pipeline, so as to introduce the waste gas discharged from the first oven. The waste gas is ignited by the flame sprayed from the flame spraying end of the burner. In this way, there is no need to set up a special waste gas treatment device to treat the waste gas, reducing the cost.
[0018] During the waste gas combustion process, heating can be carried out. Since the heat of waste gas combustion is utilized, the consumption of natural gas by the second heating component can be appropriately reduced, thereby saving the consumption of natural gas and reducing the cost.
[0019] The second heating component has the dual functions of a waste gas treatment device and the heating of the second oven, achieving two functions with one device and reducing the cost.
[0020] Since natural gas is cheap, has a high calorific value, good safety performance and environmental performance, compared with the existing heat transfer oil radiator for heating, it has the advantages of energy conservation and environmental protection.
[0021] 2. The guiding wall is designed as a flared structure because the flame ejected from the flame spraying end of the burner diffuses from the center to the outside, and the temperature of the outer flame is the highest. Therefore, the waste gas introduced from the waste gas introduction holes directly contacts the outer flame and is ignited by the outer flame, with higher combustion efficiency.
[0022] 3. According to the shape of the flame sprayed from the flame spraying end, the heat of the flame in the axial middle section of the flared structure is relatively large, while the front section and the rear section are relatively small. The diameter of the waste gas introduction holes in the corresponding middle section is larger than that of the front section and the rear section, that is, the ventilation area in the middle section is larger than that of the front section and the rear section. In this way, the waste gas airflow in the front section and the rear section is small, matching the smaller flame, and the waste gas airflow in the middle section is large, matching the larger flame. The size of the waste gas airflow matches the size of the flame, enabling full combustion. Moreover, the relatively small waste gas airflow in the front section can also avoid affecting the normal combustion of the burner due to being close to the burner.
[0023] 4. The length of the guiding wall is greater than the injection length of the flame, and the length of the distribution of several exhaust gas inlet holes before and after the guiding wall is greater than or equal to the injection length of the flame, so as to ensure that the exhaust gas introduced by the several exhaust gas inlet holes can be distributed along the entire injection length of the flame, and the combustion efficiency of the exhaust gas is higher.
[0024] 5. Since the temperature of the second oven needs to be maintained within a suitable range, but the exhaust gas flow rate is unstable and the heat generated by combustion is also unstable. If the heating power of the burner in the second heating component remains unchanged, it will cause a large temperature fluctuation in the second oven. Therefore, an exhaust gas flow rate detector is provided in the first exhaust gas delivery pipeline, and the exhaust gas flow rate detector is used to detect the exhaust gas flow rate in real time. The second heating component is provided with a second heating controller, and the second heating controller controls the heating power of the burner in the second heating component according to the exhaust gas flow rate delivered by the first exhaust gas delivery pipeline, so as to control the heat of the flame ejected by the burner in the second heating component. In this way, when superimposed with the heat generated by the exhaust gas combustion, the temperature of the second oven can be kept relatively stable.
[0025] 6. The second heating component is provided with a hot gas storage cavity connected to the guiding wall. The hot gas generated by the normal combustion of the burner and the exhaust gas combustion is stored in the hot gas storage cavity, and then is delivered to the internal space of the second oven body through a heat delivery pipeline to realize the heating of the second oven, heat the rubber hose line, and perform secondary shaping.
[0026] 7. The second heating component is circumferentially provided with an exhaust gas introduction cavity around the guiding wall. The exhaust gas introduction cavity is provided with an exhaust gas inlet, and the exhaust gas inlet is connected to the first exhaust gas delivery pipeline and a blower connected to the first exhaust gas delivery pipeline. In this way, it can ensure that the exhaust gas discharged from the first exhaust gas discharge port is stably delivered to the exhaust gas introduction cavity, and then diffuses and enters the inner side of the guiding wall from multiple directions through several exhaust gas inlet holes.
[0027] 8. The temperature of the exhaust gas in the first oven is relatively high, so it will flow upward. The first exhaust gas discharge port is arranged at the top of the first oven, which is beneficial to the exhaust gas discharge.
[0028] The second heating component is arranged above the first oven. In this way, the temperature of the exhaust gas just discharged from the first exhaust gas discharge port is relatively high, so that the exhaust gas heat can be effectively utilized. And compared with setting the second heating component close to the second oven, it can improve the heating efficiency of the second heating component, reduce the consumption of natural gas, and thus reduce the cost.

[0043] Embodiment 1
[0044] As Figures 2 to 3 shown, the present utility model provides an energy-saving and environment-friendly rubber hose shaping oven assembly, which includes a first oven 100 and a second oven 200. The first oven 100 is provided with a first oven body, an impregnating component arranged inside the first oven body, a first waste gas discharge port 12 arranged on the side wall of the first oven body, and a first heating component 11 for heating the internal space of the first oven body. The second oven 200 is provided with a second oven body and a second heating component 21 for heating the internal space of the second oven body.
[0045] During the production process of the rubber hose, the rubber hose is dipped in glue through the dipping component of the first oven and preliminarily shaped, and then heated in the second oven for secondary shaping. In the first oven, since the glue solution contains volatile organic compounds (VOCs), the exhaust gas generated during the heating process contains a large amount of volatile organic compounds. In the prior art, a special exhaust gas treatment device is used for treatment, with a large investment and high cost. In addition, the exhaust gas components are more likely to cause incomplete combustion with a general burner. In order to achieve complete combustion, a burner with a higher power or more complex structure is required, and correspondingly more energy will be consumed.
[0046] In view of this, the following improvements are made in this embodiment. First, both the first heating component 11 and the second heating component 21 adopt a burner 211 that uses natural gas combustion for heating. Since natural gas is inexpensive, has a high calorific value, good safety performance, and good environmental performance, it has the advantages of energy conservation and environmental protection compared with the existing heat-conducting oil radiator for heating.
[0047] Among them, the burner has an air inlet end and a flame jet end. Air is introduced into the air inlet end, and the flame generated by combustion is sprayed towards the flame jet end. The flame heats to generate hot gas, and then the hot gas is introduced into the internal space of the first oven body and the internal space of the second oven body to realize the heating of the first oven and the second oven. By combining the control of the power of the burner and the natural gas delivery volume, the temperature control of the first oven and the second oven is realized. The first heating component has the same structure as the conventional burner heating structure.
[0048] The first heating component includes a first burner having an air inlet end and a flame jet end, and a hot gas storage cavity connected to the flame jet end of the first burner. Air is introduced into the air inlet end, and the flame sprayed from the flame jet end of the first burner heats the hot gas storage cavity. The hot gas storage cavity is communicated with the internal space of the first oven body, and the hot gas stored in the hot gas storage cavity is transported to the internal space of the first oven body.
[0049] Secondly, as an improvement, different from the prior art, the present invention focuses on the optimization design of the second heating component 21. A guiding wall 202 is provided on one side of the flame jet end of the second burner. A plurality of exhaust gas introduction holes 203 are formed on the guiding wall. The exhaust gas introduction holes 203 are connected to the first exhaust gas discharge port 12 through a first exhaust gas transmission pipeline 13, so as to introduce the exhaust gas discharged from the first oven, and the exhaust gas is ignited by the flame sprayed from the flame jet end of the burner.
[0050] In the above technical solution, the first heating component adopts a conventional burner structure. Compared with a conventional burner, the second heating component is provided with a guiding wall on one side of the flame jet end of the burner, and a plurality of waste gas introduction holes are formed in the guiding wall. During the operation of the second heating component, air is introduced from the air inlet end. The waste gas introduction holes are arranged on one side of the flame jet end. The combustion process of air and gas entering the burner is the same as that of a conventional burner, and the burner can burn normally. The flame ejected after combustion contacts the waste gas and ignites the waste gas. In this way, the air flow rate and velocity generated by introducing the waste gas from the waste gas introduction holes hardly affect the normal combustion of the burner, and there is no need to precisely control the flow rate and velocity of the waste gas, avoiding the waste gas airflow from blowing out the burner flame.
[0051] Significantly different from the prior art where it is arranged at the air inlet end, the combustion process of air and gas entering the burner is the same as that of a conventional burner, and the burner can burn normally. The flame ejected after combustion contacts the waste gas more fully and ignites the waste gas for combustion. In this way, the combustion temperature can be ensured, and thus the temperature of other equipment can be controlled by using the heat generated from the combustion of the waste gas.
[0052] The waste gas introduction holes are connected to the first waste gas discharge port through a first waste gas delivery pipeline, thereby introducing the waste gas discharged from the first oven. The waste gas is ignited by the flame ejected from the flame jet end of the burner. In this way, there is no need to set up a special waste gas treatment device to treat the waste gas, reducing the cost.
[0053] During the combustion process of the waste gas, heating can be carried out. Since the heat of the waste gas combustion is utilized, the consumption of natural gas by the second heating component can be appropriately reduced, thereby saving the natural gas consumption and reducing the cost.
[0054] The second heating component has the dual functions of a waste gas treatment device and the heating of the second oven, achieving two functions with one device and reducing the cost.
[0055] In addition, the waste gas discharged from the first waste gas discharge port of the first oven itself has a relatively high temperature, usually greater than 200 degrees. Therefore, during the combustion process introduced into the second heating component, this part of the heat is also utilized, improving the heating efficiency of the second heating component. At the same time, during the combustion process of the waste gas, heating can be carried out, thereby saving the gas consumption and reducing the cost. More importantly, the heat of the waste gas combustion can be utilized by the second oven, realizing the internal recycling in the rubber hose shaping production equipment. Compared with using a heat exchanger to recycle the heat, the heat utilization rate is greatly improved.
[0056] Specifically, the guiding wall 202 is a flared structure with a gradually increasing diameter from front to back, that is, a conical frustum-shaped structure. Of course, as a variant, it can also be a square frustum-shaped structure, or other structures adapted to the flame shape, that is, designed according to the flame shape. This is because the flame ejected from the flame ejection end of the burner spreads from the center outwards, and the outer flame has the highest temperature. Therefore, the waste gas introduced through the waste gas introduction holes is burned by the outer flame, and the combustion efficiency is higher.
[0057] Referring to the existing burner, according to the shape of the flame ejected from the flame ejection end, the heat of the flame in the axial middle section of the flared structure is relatively large, while the front and rear sections are relatively small. Correspondingly, the diameter of the waste gas introduction holes in the middle section is larger than that in the front and rear sections, that is, the ventilation area in the middle section is larger than that in the front and rear sections. As Figure 4 shown, the waste gas introduction holes in the middle section are large-diameter holes 2032 with a diameter of D2, and the waste gas introduction holes in the front and rear sections are small-diameter holes 2031 with a diameter of D1, and D2 > D1.
[0058] In this way, the waste gas flow rate in the front and rear sections is small, which matches the smaller flame, and the waste gas flow rate in the middle section is large, which matches the larger flame. The matching of the waste gas flow rate and the flame size can achieve full combustion. Moreover, the smaller waste gas flow rate in the front section can also prevent affecting the normal combustion of the burner due to being close to the burner.
[0059] To ensure the full combustion of the waste gas, the length of the guiding wall is greater than or equal to the injection length of the flame, and the distribution length of several waste gas introduction holes in the front and back of the guiding wall is less than the injection length of the flame, so as to ensure that the waste gas introduced through several waste gas introduction holes can be distributed over the entire injection length of the flame, and the waste gas combustion efficiency is higher.
[0060] It can be understood that the shape of the waste gas introduction hole 203 is not limited and can be a round hole, a rectangular hole, an oval hole, or other shapes. Preferably, several waste gas introduction holes are arranged in a honeycomb pattern, and of course, they can be arranged in a rectangular array pattern when unfolded.
[0061] Furthermore, an exhaust gas flow detector is provided on the first exhaust gas delivery pipeline. The exhaust gas flow detector is used to detect the exhaust gas flow in real time. The second heating component is provided with a second heating controller. The second heating controller controls the heating power of the burner in the second heating component according to the exhaust gas flow delivered by the first exhaust gas delivery pipeline. Since the temperature of the second oven needs to be maintained within a suitable range, but the exhaust gas flow is unstable and the heat generated by combustion is also unstable. If the heating power of the burner in the second heating component remains unchanged, it will cause a large temperature fluctuation in the second oven. Therefore, an exhaust gas flow detector is provided on the first exhaust gas delivery pipeline, and the exhaust gas flow detector is used to detect the exhaust gas flow in real time. The second heating component is provided with a second heating controller. The second heating controller controls the heating power of the burner in the second heating component according to the exhaust gas flow delivered by the first exhaust gas delivery pipeline, thereby controlling the heat of the flame ejected by the burner in the second heating component. When superimposed with the heat generated by the exhaust gas combustion, the temperature of the second oven can be kept relatively stable.
[0062] Furthermore, the second heating component 21 further includes a hot gas storage cavity 205 connected to the guiding wall. A hot gas outlet 206 is provided at the rear side of the hot gas storage cavity 205. The hot gas storage cavity is connected with a heat delivery pipeline 22 through the hot gas outlet 206. The heat delivery pipeline 22 is communicated with the internal space of the second oven body. The hot gas generated by the normal combustion of the burner and the exhaust gas combustion is stored in the hot gas storage cavity, and then is delivered to the internal space of the second oven body through the heat delivery pipeline to realize the heating of the second oven, heat the rubber hose line, and perform secondary shaping.
[0063] Furthermore, the second heating component 21 further includes an exhaust gas introduction cavity 201 circumferentially arranged around the guiding wall. The exhaust gas introduction cavity is provided with an exhaust gas inlet 204. The exhaust gas inlet is connected to the first exhaust gas delivery pipeline, and the first exhaust gas delivery pipeline is connected with a blower. This can ensure the stable delivery of the exhaust gas discharged from the first exhaust gas discharge port to the exhaust gas introduction cavity, and then diffuse and enter the inner side of the guiding wall from multiple directions through a number of exhaust gas introduction holes.
[0064] In this embodiment, the second oven is arranged below the first oven, the first exhaust gas discharge port is arranged at the top of the first oven, the second heating component is arranged above the first oven, and a heat delivery pipeline is provided between the second heating component and the second oven. The temperature of the exhaust gas is relatively high, so it will flow upward. Arranging the first exhaust gas discharge port at the top of the first oven is conducive to exhaust gas discharge. The second heating component is arranged above the first oven. In this way, the exhaust gas just discharged from the first exhaust gas discharge port has a relatively high temperature, so that the exhaust gas heat can be effectively utilized. Compared with arranging the second heating component close to the second oven, the effective utilization of the exhaust gas heat can be further realized.
[0065] Referring to the prior art, the temperature of the internal space of the first oven body is higher than that of the internal space of the second oven body. Correspondingly, the heating temperature of the first heating assembly 11 is higher than that of the second heating assembly 21. Specifically, the model and power of the burner in the first heating assembly are both greater than those of the burner in the second heating assembly to further reduce costs. The temperature of the flame ejected from the flame ejection end of the burner in the first heating assembly is about 1200 degrees, such as 1000 - 1500 degrees. The temperature of the flame ejected from the flame ejection end of the burner in the second heating assembly is about 700 degrees, such as 500 - 800 degrees. The temperature of the hot gas in the hot gas storage cavity of the second heating assembly is 400 - 500 degrees. After being transported through the heat transfer pipeline, the temperature is further reduced. Finally, after entering the internal space of the second oven body, the temperature is about 200 degrees - 300 degrees. Therefore, the specification (power) of the burner of the second heating assembly can be smaller than that of the burner of the first heating assembly, thereby reducing costs.
[0066] It can be understood that for both the first heating assembly and the second heating assembly, a natural gas pipeline is connected to the burner, and the natural gas pipeline is connected to a manual valve and a solenoid valve. The burner is connected to an air pipeline, and the air pipeline is connected to a fan and an air volume regulating valve. In this way, according to the waste gas flow rate and the combustible content in the waste gas, adjusting the natural gas and air flow rates can make the waste gas burn fully, with precise control and a stable combustion process. Moreover, the air flow rate and velocity generated by introducing the waste gas from the waste gas inlet hole have little impact on the normal combustion of the burner, avoiding the waste gas airflow from blowing out the burner flame.
[0067] It can be understood that the first oven is equipped with a first temperature controller for real - time detection of the temperature of the first oven. The first heating assembly is equipped with a first heating controller. The first heating controller controls the heating power of the burner in the first heating assembly according to the temperature of the first oven, thereby controlling the heat of the flame ejected by the burner in the first heating assembly to keep the temperature of the first oven stable within the set range. The second oven is equipped with a second temperature controller for real - time detection of the temperature of the second oven. The second heating controller controls the heating power of the burner in the second heating assembly according to the temperature of the second oven, thereby controlling the heat of the flame ejected by the burner in the second heating assembly to keep the temperature of the second oven stable within the set range.
[0068] It can be understood that for the waste gas generated by the second oven, a second waste gas discharge port 23 is provided on the side wall of the second oven body for discharge. Since the waste gas generated by the second oven does not contain toxic and harmful substances, it does not require special treatment and can be directly discharged or undergo conventional simple treatment, which will not be elaborated here.
[0069] To avoid the situation where the waste gas after combustion treatment cannot be discharged quickly, which affects the waste gas combustion efficiency. Figure 5As shown, an exhaust gas drainage structure for guiding the hot gas generated by combustion to be discharged can also be connected to the end of the guiding wall away from the flame injection end. This can quickly discharge the hot gas generated by combustion, prevent it from accumulating inside the guiding wall, and affect the normal combustion of the waste gas, thereby improving the combustion efficiency of the waste gas. Specifically, the exhaust gas drainage structure includes a hot gas outlet 206 and a drainage pipe 208 connecting the hot gas outlet and the end of the guiding wall away from the flame injection end. The cross-sectional area of the drainage pipe gradually decreases from the guiding wall to the hot gas outlet. For example, it can be a conical pipe, a Venturi tube, or other structures that can accelerate the discharge speed of the hot gas. Additionally, it can be understood that all the structures of the second heating assembly 21 are integrated on the housing 209.
[0070] Furthermore, a flame baffle 207 can also be provided between the end of the guiding wall away from the flame injection end and the drainage pipe. The flame baffle is provided with ventilation holes. The size and arrangement area of the ventilation holes are determined according to tests to ensure that the flame can be blocked while allowing the normal passage of hot gas. The flame baffle is used to accumulate the flame inside the guiding wall to improve the combustion efficiency, and the ventilation holes allow the hot gas generated by combustion to flow into the drainage pipe, preventing the hot gas from accumulating inside the guiding wall and affecting the normal combustion of the waste gas.
[0071] Embodiment 2
[0072] As Figure 6 shown, in another embodiment, a heat exchanger 25 is also provided. The second waste gas discharge port 23 is connected to the second waste gas delivery pipeline 24.
