Description

Technical Field

[0001] The present invention specifically relates to a fume purifying trolley type forging heating furnace, and relates to the technical field of fume purification of heating furnaces. Background Art

[0002] In a trolley-type forging heating furnace, the combustion process of the fuel may not be sufficient. For example, the traditional combustion method may have unreasonable air supply, resulting in part of the fuel not being completely burned and forming smoke and dust emissions. Due to incomplete combustion, the generated smoke contains impurities such as unburned carbon particles and organic matter, and the existing purification equipment is often difficult to efficiently remove these complex components of smoke, and the smoke capture device is not perfect. For example, the design of the dust hood may be unreasonable and cannot effectively cover the area where smoke is generated. Moreover, the traditional cyclone dust collector has a low capture efficiency for fine-sized smoke particles, resulting in a large number of tiny smoke particles being directly discharged into the environment, and it is not convenient to quickly replace the air filter element. In addition, the temperature of the trolley-type forging heating furnace is very high during operation. This high-temperature environment poses a huge challenge to the cooling of the filter accessories. Due to its proximity to the heating furnace, the temperature around the filter accessories is continuously at a high temperature. Ordinary metal filter accessories are prone to thermal deformation at high temperatures, resulting in a decrease in the filtering effect. Moreover, high temperatures will accelerate the aging of the filter accessories and shorten their service life. The cooling efficiency of existing equipment is very limited. At the same time, during the operation of the trolley-type forging heating furnace, the loading and unloading and transportation methods of materials are not convenient and efficient enough, and the speed of the trolley entering and exiting the furnace body is slow, which may require more manual operations, which not only increases the labor cost, but also reduces the overall work efficiency due to the instability and time-consuming nature of manual operation; in summary, it is necessary to propose a trolley-type forging heating furnace with smoke purification to improve the above problems.

The upper surface of the truncated cone-shaped smoke collector collects the water sprayed by the spray assembly into the water-cooling filter chamber, and the water in the water-cooling filter chamber soaks and cools the truncated cone-shaped smoke collector again; The embedded installation groove on the upper side of the water-cooled filter cone can be quickly disassembled and embedded with a multi-directional filter box, and the bottom of the multi-directional filter box is connected to the lower plug-in pipe for secondary, tertiary and quadruple filtering of smoke.

The water suction hose is arranged inside the water storage chamber to pump out the water in the water storage chamber and spray it downward from the nozzles of each annular pipe, and guide the water downward from the inclined surface on the outside of the truncated cone guide cap to form a water curtain between the lower side of the truncated cone guide cap and the upper surface of the truncated cone smoke collecting tube. When the smoke in the truncated cone smoke collecting tube flows from the lower side of the truncated cone guide cap to the water-cooled filter chamber, it passes through the water curtain to perform a dust filtration.

[0009] A further improvement based on the above technical solution is that side air outlets corresponding to the box opening are opened on the four sides of the windshield inner frame, and a filter element is embedded in the inside of the windshield inner frame. The filter element filters the smoke and dust entering the side air outlet from the box opening three times, and cooperates with the electrostatic precipitator to allow dust impurities to fall to the bottom of the filter box.

When high-voltage direct current is input between the discharge electrode and the sinking electrode, anions and cations are generated in the electrode space, and act on the surface of the smoke particles passing through the electrostatic field, and move to the electrode opposite to its limit under the action of the electric field force, and are deposited on the electrode.

[0011] A further improvement based on the above technical solution is that the vibration assembly includes a screw and a sliding rod installed in parallel on the inner side of the filter box, and a moving block is arranged through the screw and the sliding rod, a driving motor for driving the screw to rotate is installed on the inner side of the filter box, and the screw is threadedly connected to the moving block, a reset vibration spring is fixedly provided at one end of the moving block adjacent to the electrostatic precipitator, and an insulating knocking rod is fixedly provided at the end of the reset vibration spring, and the active displacement of the insulating knocking rod is utilized to vibrate and knock the discharge electrode and the sinking electrode respectively, causing the smoke particles deposited on their surfaces to fall to the bottom of the filter box.

When the smoke passes through the side air outlets on the four sides, it can be filtered for the third time by the activated carbon filter plates on the four sides, and then filtered four times by the activated carbon filter plate on the upper side of the rectangular mounting frame, and finally transported upward into the air duct.

[0013] A further improvement based on the above technical solution is that the first longitudinal rail and the second longitudinal rail are both connected to the longitudinal frame in a forward and backward rolling manner, and the first longitudinal rail, the second longitudinal rail and the third longitudinal rail are all provided with guide rails corresponding to the transverse rails, and the guide rails are used to send the longitudinal frame of the first longitudinal rail or the second longitudinal rail into the third longitudinal rail, and the third longitudinal rail is arranged on the inner side of the lower movable groove, and a placement table for placing forging materials is provided on the upper side of the longitudinal frame for lifting and lowering, and a lifter is installed between the longitudinal frame and the placement table for lifting and jacking up the placement table, and closed convex edges are provided on four sides of the placement table, and when the placement table is lifted upward, the closed convex edges can be pressed against the lower edge of the upper heating chamber for sealing, and a hinged door is rotatably connected to the front side of the upper heating chamber, and the hinged door is locked to the front side of the heating furnace body by a lock.

[0014] By adopting the above technical solution, the present invention has the following advantages: 1. The structure of the present invention is compact and ingenious. By installing a water-cooled filter cone on the upper side of the heating furnace body, the flue gas can quickly enter the water-cooled filter cone under the heat flow of the heating furnace body and the air extraction effect of the air duct, and the truncated cone smoke collector installed in the water-cooled filter chamber is used to centrally transport high-temperature smoke and dust, so that most of the heat can be conducted to the truncated cone smoke collector and the spray assembly, and the spray assembly sprays an annular water curtain downward to cool the truncated cone smoke collector body. At the same time, under the immersion of filtered water in the water-cooled filter chamber, the truncated cone smoke collector and the water-cooled filter cone body can also be cooled. At the same time, when the spray assembly sprays an annular water curtain downward, the smoke and dust blown out of the truncated cone smoke collector can also be cooled and filtered by a water flow dust reduction function; At the same time, a plurality of nozzles are installed in a circular array at the bottom of the annular tube of the spray assembly, so that the water flow sprayed downward by the nozzles is directed downward along the inclined surface of the truncated cone guide cap, and the formed water curtain cavity can surround the upper side of the truncated cone smoke collector, so that when the smoke is discharged from the lower side of the truncated cone guide cap, it can fully contact with the water flow, and the inverted cone diverter arranged on the inner side of the truncated cone guide cap facing the truncated cone smoke collector can disperse the smoke to four sides, and the smoke is evenly dispersed to the water curtain by the air flow dispersion net, so as to avoid excessive concentration of smoke, further improve the contact between the smoke and the water curtain, and then promote the cooling and filtering effect; 2. A water purifier is also provided to extract and purify the filtered water from the water-cooling filter chamber, and to prevent the water level in the water-cooling filter chamber from being too high. The output end of the water purifier is connected to a cooling tower to cool the water again, and then transport it to the water storage chamber for storage, forming a complete water-cooling filtration cycle, which is economical and environmentally friendly. 3. A multi-directional filter box is embedded in the installation slot on the upper side of the water-cooled filter cone. The multi-directional filter box can be quickly disassembled and assembled by pulling out the portable handle, which is beneficial to the speed of later replacement. The multi-directional filter box is mainly sleeved on the lower plug-in pipe in the middle of the embedded installation slot through the upper plug-in pipe, which improves the connection stability while allowing the lower plug-in pipe to communicate with the inside of the multi-directional filter box. Since the four sides of the multi-directional filter box are respectively embedded with filter boxes, the smoke dust after the primary filtration can be further dispersed, and the smoke dust particles are deposited and adsorbed by the electric field force of the electrostatic precipitator in the four filter boxes, so as to achieve secondary dispersion and purification of the smoke dust; Among them, the vibration component can quickly knock the dust impurities deposited by the electrostatic precipitator into the groove at the bottom of the filter box for centralized collection. When cleaning these waste materials later, the filter box can be quickly cleaned or replaced by removing it, which is simple and convenient to use; 4. After the secondary filtration and purification, the flue gas can pass through the side air outlet and enter the filter element embedded in the top of the multi-directional filter box for third and fourth filtration and purification. The filter element is mainly equipped with activated carbon filter plates at the filter ports on the four sides and the top of the rectangular mounting frame. The activated carbon filter plates on the four sides perform the third filtration and purification respectively, and when the activated carbon filter plates on the four sides filter dust impurities, the electric field force of the electrostatic precipitator can deposit the dust impurities filtered on the outside of the activated carbon filter plates on the four sides, ensuring the use efficiency of the active carbon filter plates on the four sides and the purification effect on the smoke. The activated carbon filter plate at the top filter port is the last smoke filtration step, which can ensure that the smoke filtered by the activated carbon filter plates on the four sides is further purified, greatly improving the overall purification effect of the water-cooled filter cone. Moreover, the entire filter element can also be quickly disassembled and replaced separately according to the later use needs.

[0015] 5. By providing the first longitudinal rail, the second longitudinal rail and the third longitudinal rail to cooperate with the transverse rail, the longitudinal frames on the first longitudinal rail, the second longitudinal rail and the third longitudinal rail can be transported alternately by the transverse frames on the transverse rail. In this way, when the materials loaded on the placing table of the longitudinal frame on the upper side of the third longitudinal rail are sent into the heating furnace body for heating and forging, the transverse frames on the first longitudinal rail or the second longitudinal rail can load and unload materials at the same time, which is conducive to improving work efficiency.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figure 1-14As shown, the present invention provides a technical solution for a trolley-type forging heating furnace with smoke purification, comprising a transverse rail 1, a transverse frame 2 rollingly arranged on the upper side of the transverse rail 1, a first longitudinal rail 31, a second longitudinal rail 32 and a third longitudinal rail 33 vertically arranged on the rear side of the transverse rail 1, and a heating furnace body 5 arranged directly above the third longitudinal rail 33, the first longitudinal rail 31 and the second longitudinal rail 32 are both connected with a longitudinal frame 34 in a front-rear rolling manner, the first longitudinal rail 31, the second longitudinal rail 32 and the third longitudinal rail 33 are all provided with a guide rail 4 corresponding to the transverse rail 1, and the guide rail 4 is used to send the longitudinal frame 34 of the first longitudinal rail 31 or the second longitudinal rail 32 into the third longitudinal rail 33, the third longitudinal rail 33 is arranged on the inner side of the lower movable groove 51, for example, after the material is assembled by the longitudinal frame 34 on the first longitudinal rail 31, it can be transported to the transverse frame 2 on the upper side of the transverse rail 1 through the guide rail 4, and then the longitudinal frame 34 is transported to the front side of the third longitudinal rail 33 by the transverse frame 2, and sent into the third longitudinal rail 33, at this time, the longitudinal frame 34 equipped with the material is arranged on the inner side of the lower heating furnace body 5 for processing, so that the alternating conveying of the longitudinal frame 34 can be realized. While the longitudinal frame 34 on the third longitudinal track 33 is processing the material, the longitudinal frame 34 on the outer second longitudinal track 32 can be loaded and unloaded synchronously, which can greatly improve the conveying efficiency. A placing table 341 for placing the forging material is provided on the upper side of the longitudinal frame 34, and a lifter 35 is installed between the longitudinal frame 34 and the placing table 341 for lifting the placing table 341. 41 is lifted up, and the lifter 35 is a lifting mechanism in the prior art. It only needs to lift the placement table 341. The placement table 341 is provided with closed convex edges 342 on four sides. When the placement table 341 is lifted upward, the closed convex edges 342 can be pressed against the lower edge of the upper heating chamber 52 for sealing. The upper heating chamber 52 is rotatably connected to the front side with a hinged door 53, and the hinged door 53 is locked to the front side of the heating furnace body 5 by using a lock 531. The lock 531 is a door locking mechanism in the prior art. It only needs to lock the hinged door 53.

[0019] In this embodiment, the heating furnace body 5 is provided with a lower movable wheel groove 51 and an upper heating chamber 52 in sequence from bottom to top, and the heating furnace body 5 at the top of the upper heating chamber 52 is connected to four smoke through holes 54 for exhausting smoke upwards, and a water-cooled filter cone 6 is installed on the top of the heating furnace body 5, and four truncated cone-shaped smoke collecting tubes 60 are integrally provided at the bottom of the water-cooled filter cone 6, and the truncated cone-shaped smoke collecting tubes 60 are connected to the smoke through holes 54, so that smoke can enter the water-cooled filter cone 6 through the four truncated cone-shaped smoke collecting tubes 60 respectively, and an air duct 7 is installed on the top of the water-cooled filter cone 6, and a fan 71 is installed at the end of the air duct 7, when the fan 71 draws air, a negative pressure is generated inside the water-cooled filter cone 6 to increase the flow speed of smoke; The inner side of the water-cooled filter cone 6 is provided with a water-cooled filter chamber 61, a water storage chamber 62 and an embedded installation slot 64 from bottom to top. A lower plug-in pipe 63 connected to the top of the water-cooled filter chamber 61 is installed in the middle of the lower side of the embedded installation slot 64. Each truncated cone-shaped smoke collecting tube 60 protrudes inwardly from the inner side of the water-cooled filter chamber 61, so that the water-cooled filter chamber 61 is connected to the smoke through hole 54 through the truncated cone-shaped smoke collecting tube 60. An inner horizontal plate 65 is installed, and nine through-holes 651 are opened in the middle of the inner horizontal plate 65, and are staggered above the truncated cone-shaped smoke collecting tube 60, so that smoke can flow upward to the lower plug-in pipe 63. Gas-liquid separators can also be installed at the through-holes 651 to reduce the upward loss of water mist. Four spray assemblies 66 corresponding to the top of the truncated cone-shaped smoke collecting tube 60 are installed on the lower side of the inner horizontal plate 65, which are used to draw water from the water storage chamber 62 and spray it downward to the truncated cone-shaped smoke collecting tube 60 in the form of an annular water curtain. The upper surface of the smoke collecting tube 60 can guide the water liquid and fully contact the water liquid because the truncated cone-shaped smoke collecting tube 60 is an inclined surface, which can play a role in cooling the flow of the truncated cone-shaped smoke collecting tube 60. In addition, the annular downward-flowing water curtain can filter the smoke blown out of the truncated cone-shaped smoke collecting tube 60. In addition, since the truncated cone-shaped smoke collecting tube 60 is a truncated cone shape with a narrow bottom and a wide top, it is used to gather and pressurize the smoke generated by the heating furnace body 5, so that the heat is concentrated on the truncated cone-shaped smoke collecting tube 60 and the spray assembly 66, and cooled under the action of the water flow, which can improve the service life of the accessories. In addition, the upper surface of the truncated cone-shaped smoke collecting tube 60 guides and collects the water sprayed by the spray assembly 66 to the water-cooled filter chamber 61. The water gathered at the bottom of the water-cooled filter chamber 61 again immerses and cools the outer side of the truncated cone-shaped smoke collecting tube 60, and can reduce the conduction heat of the water-cooled filter cone 6 in contact with the heating furnace body 5, thereby reducing the impact of high temperature on use. A multi-directional filter box 67 is embedded in the embedded installation slot 64 on the upper side of the water-cooled filter cone 6 for quick disassembly and assembly, and the bottom of the multi-directional filter box 67 is plugged and connected with the lower plug-in pipe 63 for secondary, tertiary and quadrature filtering of smoke and dust. Specifically, the multi-directional filter box 67 includes a hollow frame 670, and ventilation slots 671 are respectively provided on the upper, lower, front, rear, left and right sides of the hollow frame 670, wherein an upper plug-in pipe 672 is fixedly provided on the inner side of the lower ventilation slot 671, and the top height of the upper plug-in pipe 672 is located in the middle of the ventilation slots 671 on the front, rear, left and right sides, and the lower plug-in pipe 672 is located in the middle of the ventilation slots 671 on the front, rear, left and right sides. The plug-in pipe 63 can be adapted to be plugged into the inner side of the lower ventilation slot 671 and the upper plug-in pipe 672. A windshield inner frame 673 is fixedly arranged inside the upper ventilation slot 671. The windshield inner frame 673 is located directly above the upper plug-in pipe 672 and is used to disperse the smoke and dust gas to the ventilation slots 671 on the four sides. A hand-held handle 675 for pulling out is installed on the top of the hollow frame 670, so that the multi-directional filter box 67 can be quickly disassembled and assembled. When it is necessary to clean or replace the internal components of the filter box, the operator can easily pull out the multi-directional filter box 67, which greatly saves maintenance time and workload. The ventilation slots 671 at the front, rear, left and right sides are sealed and embedded with filter boxes 676, and the opposite side of each filter box 676 is provided with a box opening 6761 connected to the ventilation slot 671. Each filter box 676 is relatively independent. When a filter box 676 fails or needs to be cleaned separately, it can be operated separately without affecting the normal operation of other filter boxes 676, thereby improving the reliability and flexibility of the entire filtering system. An electrostatic precipitator 677 is installed on the inside of the filter box 676. When the smoke enters the multi-directional filter box 67 from the lower plug-in pipe 63 through the upper plug-in pipe 672, the windshield inner frame 673 on the inner side of the upper ventilation slot 671 disperses the smoke gas to the ventilation slots 671 on the four sides, so that the smoke can evenly enter each filter box 676. Inside the filter box 676, the electrostatic precipitator 677 performs secondary filtration and dust removal on the smoke. The electrostatic precipitator 677 includes a plurality of discharge electrodes 6771 and sinking electrodes 6772 arranged vertically adjacent to each other. The electrostatic precipitator 677 inputs high-voltage direct current between the discharge electrode 6771 and the sinking electrode 6772 to generate anions and cations in the electrode space. The smoke particles move to and deposit on the opposite electrode under the action of the electric field force, thereby effectively removing particulate matter in the smoke and greatly improving the degree of purification of the smoke.

[0020] Moreover, the vibration assembly arranged in the filter box 676 can regularly vibrate and knock the electrostatic precipitator 677. The vibration assembly drives the screw 681 to rotate through the driving motor 686, so that the moving block 683 moves under the guidance of the screw 681 and the sliding rod 682, and utilizes the reset vibration spring 684 and the insulating knocking rod 685 to knock the discharge electrode 6771 and the sinking electrode 6772 respectively. In this way, the dust impurities deposited on the electrodes will fall to the bottom of the filter box 676 for collection, avoiding excessive accumulation of dust on the electrodes to affect the filtering effect of the electrostatic precipitator 677, and also facilitating the centralized treatment of dust impurities.

[0021] 6741 is embedded in the inner side of the windshield inner frame 673, so that the installation of the filter element 674 in the multi-directional filter box 67 is stable and reasonable. This embedded installation can ensure that the filter element 674 will not be displaced due to factors such as vibration during the operation of the equipment, thereby ensuring the stability of the filtering process and convenient for later disassembly and assembly. Filter openings 6742 are respectively provided on the front, rear, left, right and upper sides of the rectangular mounting frame 6741, and each filter opening 6742 is installed with an activated carbon filter plate 6743. When the smoke passes through the side air openings 6731 on the four sides, it can be filtered for the third time by the activated carbon filter plates 6743 on the four sides. This all-round filtering design can more comprehensively capture the smoke and dust. impurities, avoiding dead corners or blockages that may exist due to single-direction filtering, and improving the filtering efficiency and purification effect of the entire filter element 674 on smoke; then it is filtered four times through the activated carbon filter plate 6743 on the upper side of the rectangular mounting frame 6741, and finally transported upward to the air duct 7. That is to say, when the smoke after the secondary filtration enters the filter element 674 from the box mouth 6761 through the side air outlet 6731, the activated carbon filter plates 6743 on the four sides of the rectangular mounting frame 6741 begin to play a role. The activated carbon filter plate 6743 has a rich pore structure and can absorb tiny particles, harmful gases and other impurities in the smoke. The activated carbon filter plates 6743 on the four sides are respectively filtered for the third time, which further improves the purification degree of the smoke and removes the harmful substances that still remain after the secondary filtration; after being filtered three times by the activated carbon filter plates 6743 on the four sides, the smoke continues to be filtered four times upward through the activated carbon filter plates 6743 on the upper side of the rectangular mounting frame 6741. This filtering process serves as the final safeguard and can intercept extremely small particles or harmful substances that may have been missed before, ensuring that the smoke and dust that are ultimately transported upward into the air duct 7 reaches a high purification standard, thereby greatly reducing smoke and dust pollutants discharged into the environment.

[0022] In the above technical scheme, a waste baffle 6762 is arranged at the box mouth 6761 and is flush with the upper plug-in pipe 672, so that a groove is formed at the bottom of the filter box 676. Under the action of the electric field force of the electrostatic precipitator 677, the dust impurities intercepted by the filter element 674 can fall down into the groove at the bottom of the filter box 676 for centralized collection, effectively preventing the dust from scattering around in the filter box 676, facilitating the subsequent cleaning and treatment of the dust. In the above process, there is a synergistic effect between the filter element 674 and the electrostatic precipitator 677. When the electrostatic precipitator 677 performs secondary filtration, its electric field force not only deposits and adsorbs the smoke particles, but also causes the dust impurities filtered by the four-side activated carbon filter plates 6743 to fall down to the bottom of the filter box 676. This collaborative working mechanism improves the efficiency of the entire filtration system, enables each filtration link to cooperate with each other, and better realizes the functions of smoke purification and dust collection.

[0023] In this embodiment, a water purifier 8 and a water cooling tower are also included. The water inlet end of the water pump of the water purifier 8 is connected to the bottom of the water cooling filter chamber 61 through a water pipe, which is used to filter the spray dust precipitation, and the water outlet end of the water purifier 8 is connected to the water cooling tower through a water pipe. The water cooling tower reconnects the water to the inner side of the water storage chamber 62 after cooling, forming a water cooling filtration cycle, ensuring that there is always a suitable amount of water in the water cooling filter chamber 61 for the cooling and filtering operation of the spray component 66 on the smoke. The stable water supply helps to maintain the stable operation of the entire smoke purification system, ensuring that each Each link such as the cooling of the truncated cone-shaped smoke collecting tube 60 and the water curtain filtration of smoke can be carried out continuously and effectively. A water injection port 621 is provided on the upper side of the water storage chamber 62. When the amount of water is reduced due to evaporation of water during operation of the system, water can be conveniently replenished through the water injection port 621. At the same time, this water injection port 621 also provides convenience for the debugging and cleaning of the system. For example, when the system is first operated or restarted after maintenance, the amount of water in the water storage chamber 62 can be adjusted to a suitable level through the water injection port 621.

[0024] Based on the above technical solution, the spray assembly 66 includes a plurality of truncated cone-shaped flow guide caps 661 and a spray pump 666. The spray pump 666 is installed on the inner side of the bottom of the embedded installation slot 64. Each truncated cone-shaped flow guide cap 661 is spaced apart and arranged on the upper side of each truncated cone-shaped smoke collecting tube 60. The truncated cone-shaped flow guide cap 661 is staggered from the opening 651 and installed on the lower side of the inner horizontal plate 65. This installation method is matched with the layout of the truncated cone-shaped smoke collecting tube 60, and optimizes the flow of smoke and dust. The outer side of the truncated cone-shaped guide cap 661 is fixed with a ring tube 663, and the lower side of the ring tube 663 is equipped with a plurality of nozzles 664 facing downwards and corresponding to the inclined surface of the truncated cone-shaped guide cap 661. One side of the ring tube 663 is connected with a connecting pipe 665, and the connecting pipe 665 penetrates through the bottom of the installation slot 64 and is connected to the water outlet of the spray pump 666. The water inlet of the spray pump 666 is connected with a water pump hose 667, which penetrates through the water storage chamber 6 2, the spray pump 666 draws out the water in the water storage chamber 62, sprays it downward through the connecting pipe 665, the annular pipe 663 and the nozzle 664, and guides the water downward through the inclined surface of the outer side of the truncated cone guide cap 661, so that a water curtain is formed between the lower side of the truncated cone guide cap 661 and the upper surface of the truncated cone smoke collecting tube 60. When the smoke in the truncated cone smoke collecting tube 60 flows to the water-cooled filter chamber 61, it must pass through this water curtain. The water curtain can absorb particles in the smoke, so that some impurities in the smoke are absorbed and settled by water, realizing a one-time filtration and dust settling of the smoke, greatly reducing the pollutant content in the smoke, and in the process of the smoke passing through the water curtain, the evaporation of water will absorb heat, thereby cooling the smoke, which is not only helpful for the subsequent smoke treatment process, for example, in the subsequent filtering process, the cooled smoke is easier to be absorbed and intercepted by the filter medium, but also reduces the temperature of the smoke, reducing the risk of equipment damage caused by high temperature, etc.

[0025] Furthermore, an airflow dispersion net 662 is installed at the lower opening of the truncated cone-shaped guide cap 661, the inner side of which is in close contact with the outer side of the truncated cone-shaped smoke collecting tube 60, and an inverted cone-shaped diverter 6612 is installed at the inner top of the truncated cone-shaped guide cap 661, the bottom of which is facing the tube mouth at the top of the truncated cone-shaped smoke collecting tube 60, for dispersing smoke to the four sides of the inside of the truncated cone-shaped guide cap 661, and then the airflow dispersion net 662 further filters and disperses the smoke, so that the smoke can be dispersed evenly. This uniform dispersion effect is conducive to the full contact between the smoke and the water curtain, and improves the efficiency of the primary filtration dust drop.

[0026] The specific working principle includes the following steps: Material transportation: Since the first longitudinal track 31, the second longitudinal track 32 and the third longitudinal track 33 are provided to cooperate with the transverse track 1, the longitudinal frames 34 on the first longitudinal track 31, the second longitudinal track 32 and the third longitudinal track 33 can be transported alternately by the transverse frame 2 on the transverse track 1, so that when the material loaded on the placing table 341 of the longitudinal frame 34 on the upper side of the third longitudinal track 33 is sent into the heating furnace body 5 for heating and forging, the transverse frame 2 on the first longitudinal track 31 or the second longitudinal track 32 The materials can be loaded and unloaded at the same time, so that the loading and unloading and heating processes can be carried out at the same time, which can improve the overall work efficiency. In addition, the third longitudinal track 33 is located in the lower movable vehicle groove 51 on the lower side of the heating furnace body 5. The longitudinal vehicle frame 34 drives the placement table 341 to rise and fall through the lifter 35. The four sides of the placement table 341 are provided with closed convex edges 342. After lifting, they are sealed with the lower edge of the upper heating chamber 52, and then the hinged door 53 is closed and locked with the locker 531, so that a closed space is formed in the heating furnace body 5 to prevent heat leakage. Smoke cooling and primary purification process: the smoke generated when the heating furnace body 5 is working enters the water-cooled filter cone 6 through the smoke through hole 54. The fan 71 draws air to generate negative pressure in the water-cooled filter cone 6, which accelerates the flow of smoke; the spray assembly 66 draws water from the water storage chamber 62, and sprays it downward through the nozzle 664 of the annular tube 663, and forms an annular water curtain under the guiding effect of the inclined surface of the truncated cone guide cap 661. In the water-cooled filter chamber 61, since the diameter of the truncated cone smoke collecting tube 60 is reduced from bottom to top, the heat can be concentrated on the truncated cone smoke collecting tube 60 and the spray assembly 66, and the truncated cone guide cap 661 is used to guide the water in the water-cooled filter chamber 61. The smoke blown out from the cap 661 toward the inverted cone-shaped flow divider 6612 can disperse and flow to the four sides, and be evenly dispersed to the water curtain wall through the airflow dispersion net 662, so as to avoid excessive concentration of smoke pressure and affect the flow of the water curtain, further improve the contact dust fall between the smoke and the water curtain wall, and then promote the filtering and cooling effect of the smoke, as well as the cooling effect of the smoke and accessories. This can effectively cool down the main body of the truncated cone-shaped smoke collector 60. At the same time, the truncated cone-shaped smoke collector 60 can also cool down the main body of the truncated cone-shaped smoke collector 60 and the water-cooled filter cone 6 when immersed in the filtered water of the water-cooled filter chamber 61, thereby improving the service life; Water-cooled filtration circulation system: dust impurities filtered by the water curtain dust fall into the water-cooled filter chamber 61. By setting a water purifier 8, the filtered water in the water-cooled filter chamber 61 can be extracted and purified, and the water level in the water-cooled filter chamber 61 can be prevented from being too high. The output end of the water purifier 8 is connected to the cooling tower to cool the water again, and then re-transport it to the water storage chamber 62 for storage, forming a complete water-cooled filtration cycle, realizing the recycling of water resources, promoting the effects of cooling and filtering, saving water resources, and reducing wastewater discharge; Secondary filtration and purification of smoke: The smoke that has undergone the above-mentioned primary filtration and purification enters the lower plug-in pipe 63 from each opening 651, and enters the upper plug-in pipe 672 of the multi-directional filter box 67 from the lower plug-in pipe 63. Under the obstruction of the bottom of the windshield inner frame 673, the smoke is dispersed into the filter box 676 through the ventilation slots 671 on the four sides. The electrostatic precipitator 677 in the filter box 676 works, and anions and cations are generated in the electrode space when high-voltage direct current is input between the discharge electrode 6771 and the sinking electrode 6772, and act on the surface of the smoke particles passing through the electrostatic field. Under the action of the electric field force, the smoke moves to the electrode opposite to its limit and is deposited on the electrode, thereby achieving the purpose of filtering out the smoke. Secondary filtration and purification of dust. After a certain period of time, the vibration component works, and the screw 681 is driven to rotate by the driving motor 686. The screw 681 threadedly drives the moving block 683 to move along the discharge electrode 6771 and the sinking electrode 6772, so that the insulating knocking rod 685 connected by the reset vibration spring 684 on the moving block 683 knocks the discharge electrode 6771 and the sinking electrode 6772, so that the deposited and adsorbed dust impurities quickly fall into the groove at the bottom of the filter box 676 for centralized collection, and when cleaning these wastes later, the filter box 676 can be removed to quickly clean or replace the filter box 676, thereby improving the efficiency and convenience of later maintenance and use; Three and four times efficient filtration and purification of smoke and dust: after the secondary filtration and purification, the smoke can enter the filter element 674 embedded and installed on the top of the multi-directional filter box 67 through the side air outlet 6731 for three and four times of filtration and purification. The filter element 674 is mainly installed with activated carbon filter plates 6743 on the four sides and the filter port 6742 on the top of the rectangular mounting frame 6741. The activated carbon filter plates 6743 on the four sides perform the third filtration and purification respectively, and when the activated carbon filter plates 6743 on the four sides filter dust impurities, the electric field force of the electrostatic precipitator 677 can act on the dust impurities filtered on the outside of the activated carbon filter plates 6743 on the four sides, ensuring that the activated carbon filter plates 674 3 improves the efficiency of use and the purification effect on smoke dust, and the activated carbon filter plate 6743 of the top filter port 6742 serves as the last smoke dust filtering step, which can ensure that the smoke filtered by the activated carbon filter plates 6743 on the four sides is further purified, thereby greatly improving the overall purification effect of the water-cooled filter cone 6, and finally discharged to the outside by the air duct 7 and the fan 71, or connected to the next purification process. Through multiple filtration and cooling, harmful substances and impurities in the smoke can be effectively removed, which greatly improves the purification effect and reduces pollution to the environment. Moreover, the entire filter element 674 can also be quickly disassembled and assembled, which is convenient for later cleaning and replacement, and reduces maintenance costs.
