Description

Technical Field

[0001] The present invention specifically relates to a trolley-type forging heating furnace for soot purification, and pertains to the technical field of flue gas purification of heating furnaces. Background Art

[0002] In a trolley-type forging heating furnace, the combustion process of fuel may not be sufficient. For example, in traditional combustion methods, the air supply may be unreasonable, resulting in some fuel being discharged as soot without complete combustion. Due to incomplete combustion, the generated soot contains impurities such as unburned carbon particles and organic substances. Existing purification equipment often has difficulty efficiently removing such complex-component soot, and the soot capture device is not perfect. For example, the design of the dust collection hood may be unreasonable and cannot effectively cover the area where soot is generated. Moreover, traditional cyclone dust collectors have low capture efficiency for fine-particle soot, resulting in a large amount of tiny soot particles being directly discharged into the environment, and it is not convenient to quickly replace the air filter element. Also, when the trolley-type forging heating furnace is working, the temperature is very high, which poses a huge challenge to the cooling of the filter fittings. Since it is close to the heating furnace, the temperature around the filter fittings remains at a high temperature continuously. Ordinary metal filter fittings are prone to thermal deformation at high temperatures, leading to a decline in the filtering effect. Moreover, high temperature will accelerate the aging of the filter fittings and shorten their service life. The cooling efficiency of existing equipment is very limited.

[0003] At the same time, during the operation of the trolley-type forging heating furnace, the loading, unloading, and conveying method of materials is not convenient and efficient enough. The speed of the trolley entering and leaving the furnace body is slow, and more manual operations may be required. This not only increases the labor cost but also reduces the overall working efficiency due to the instability and time-consuming nature of manual operations. In summary, it is necessary to propose a trolley-type forging heating furnace for soot purification to improve the above problems. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a trolley-type forging heating furnace for soot purification to solve the problems of poor soot purification, cooling effect, and working efficiency mentioned in the above background art.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: A trolley-type forging heating furnace for soot purification includes a transverse track, a transverse vehicle frame rolling on the upper side of the transverse track, a first longitudinal track, a second longitudinal track, and a third longitudinal track vertically arranged behind the transverse track, and a heating furnace body arranged directly above the third longitudinal track.

[0006] The heating furnace body is successively provided with a lower movable carriage groove and an upper heating cavity from bottom to top, and a plurality of flue gas through holes are communicated with the heating furnace body at the top of the upper heating cavity. A water-cooled filtering pyramid cylinder is installed at the top of the heating furnace body. A plurality of frustum-shaped smoke collecting cylinders are integrally arranged at the bottom of the water-cooled filtering pyramid cylinder and are communicated with the flue gas through holes through the frustum-shaped smoke collecting cylinders;

[0007] A wind pipe is installed at the top of the water-cooled filtering pyramid cylinder, and a fan is installed at the end of the wind pipe. When the fan sucks air, a negative pressure is generated inside the water-cooled filtering pyramid cylinder to increase the flow rate of the soot;

[0008] Inside the water-cooled filtering pyramid cylinder, a water-cooled filtering cavity, a water storage cavity and an embedded installation notch are successively arranged from bottom to top. A lower insertion pipe communicated with the top of the water-cooled filtering cavity is installed in the middle of the lower side of the embedded installation notch. Each frustum-shaped smoke collecting cylinder protrudes inward from the inner side of the water-cooled filtering cavity, so that the water-cooled filtering cavity is communicated with the flue gas through holes through the frustum-shaped smoke collecting cylinders. An inner horizontal plate is installed in the middle of the water-cooled filtering cavity, and a plurality of through holes are opened in the middle of the inner horizontal plate to allow the flue gas to flow upward to the lower insertion pipe;

[0009] A plurality of spray components corresponding above the frustum-shaped smoke collecting cylinders are installed on the lower side of the inner horizontal plate, which are used to pump out the water in the water storage cavity and spray it downward in an annular water curtain onto the upper surface of the frustum-shaped smoke collecting cylinder to filter the soot blown out by the frustum-shaped smoke collecting cylinder once and cool the frustum-shaped smoke collecting cylinder;

[0010] Since the frustum-shaped smoke collecting cylinder is in the shape of a frustum with a wider bottom and a narrower top, it is used to gather and pressurize the soot generated by the heating furnace body, so that the heat is concentrated on the frustum-shaped smoke collecting cylinder and the spray components for cooling. The water sprayed by the spray components on the upper surface of the frustum-shaped smoke collecting cylinder is diverted and collected into the water-cooled filtering cavity, and the water in the water-cooled filtering cavity cools the frustum-shaped smoke collecting cylinder by soaking again;

[0011] A multi-directional filter box is quickly disassembled and embedded in the embedded installation notch on the upper side of the water-cooled filtering pyramid cylinder, and the bottom of the multi-directional filter box is inserted and communicated with the lower insertion pipe for secondary, tertiary and quaternary filtering of the soot.

[0012] Based on the above technical solution, a further improvement is that it also includes a water purifier and a water cooling tower. The water pump inlet end of the water purifier is connected to the bottom of the water-cooled filtering cavity through a water pipe for filtering the sprayed and precipitated water, and the water outlet end of the water purifier is connected to the water cooling tower through a water pipe. The water cooling tower cools the water and then reconnects it to the inside of the water storage cavity to form a water-cooled filtering cycle. A water injection port is opened on the upper side of the water storage cavity.

[0013] Further improvements based on the above technical solution are as follows: The spray assembly includes a plurality of frustum-shaped flow guide caps and a spray pump. The spray pump is installed inside the bottom of the embedded installation notch. Each frustum-shaped flow guide cap is respectively and spacedly sleeved on the upper side of each frustum-shaped smoke collecting cylinder, and the frustum-shaped flow guide caps are installed under the inner horizontal plate with the through openings staggered. A circular pipe is fixedly provided on the outer side of the frustum-shaped flow guide cap, and a plurality of nozzles are installed on the lower side of the circular pipe and are arranged corresponding to the inclined surfaces of the frustum-shaped flow guide caps downward. One side of the circular pipe is connected with a connecting pipe, and the connecting pipe penetrates through the bottom of the embedded installation notch and is connected with the water outlet end of the spray pump. The water inlet end of the spray pump is connected with a water suction hose, and the water suction hose is arranged inside the water storage cavity in a penetrating manner, used to pump out the water in the water storage cavity and spray it downward through the nozzles of each circular pipe, and flow downward along the inclined surface on the outer side of the frustum-shaped flow guide cap, so as to form a water curtain between the lower side of the frustum-shaped flow guide cap and the upper surface of the frustum-shaped smoke collecting cylinder. When the soot in the frustum-shaped smoke collecting cylinder flows from the lower side of the frustum-shaped flow guide cap to the water-cooled filtering cavity, it passes through this water curtain for primary dust filtering and sedimentation.

[0014] Further improvements based on the above technical solution are as follows: An air flow dispersion net is installed at the lower opening of the frustum-shaped flow guide cap. The inner side of the air flow dispersion net is closely attached to the outer side of the frustum-shaped smoke collecting cylinder, and an inverted cone-shaped flow dividing part is installed at the top inside the frustum-shaped flow guide cap. The sharp end of the bottom end of the inverted cone-shaped flow dividing part faces the barrel opening at the top of the frustum-shaped smoke collecting cylinder, used to disperse the soot to the four sides inside the frustum-shaped flow guide cap and evenly disperse it under the filtering of the air flow dispersion net.

[0015] Further improvements based on the above technical solution are as follows: The multi-directional filter box includes a hollow frame body. Ventilation notches are respectively opened on the upper, lower, front, rear, left and right sides of the hollow frame body. Among them, an upper insertion pipe is fixedly provided inside the lower ventilation notch, and the top height of the upper insertion pipe is located at the middle positions of the ventilation notches on the front, rear, left and right sides. The lower insertion pipe can be adaptively inserted inside the lower ventilation notch and the upper insertion pipe. A wind blocking inner frame body is fixedly provided inside the upper ventilation notch, and the wind blocking inner frame body is located directly above the upper insertion pipe, used to disperse the soot gas to the ventilation notches on the four sides. A handgrip for pulling is installed on the top of the hollow frame body. Filter boxes are hermetically inserted and installed in the ventilation notches on the front, rear, left and right sides respectively. A box opening communicating with the ventilation notch is provided on the opposite side of each filter box. An electrostatic precipitator is installed inside the filter box. When the soot in the upper insertion pipe enters through the box opening, it is secondarily filtered and dust-removed by the electrostatic precipitator, and a vibration component for vibrating and knocking the electrostatic precipitator is provided inside the filter box to shake off the dust impurities deposited on the electrostatic precipitator to the bottom of the filter box for collection.

[0016] Further improvement based on the above technical solution is that side air vents corresponding to and communicating with the box opening are provided on four sides of the windshield inner frame body. A filter element is embedded and installed inside the windshield inner frame body. The filter element performs three - stage filtering on the soot entering the side air vents from the box opening, and cooperates with the electrostatic precipitator to enable dust impurities to fall downward to the bottom of the filter box.

[0017] Further improvement based on the above technical solution is that a waste baffle flush with the height of the upper insertion pipe is provided at the box opening, so that a groove is formed at the bottom of the filter box for concentrating and collecting dust waste. The electrostatic precipitator includes a plurality of discharge electrodes and collecting electrodes arranged vertically adjacent to each other. When high - voltage direct current is input between the two levels of the discharge electrode and the collecting electrode, positive and negative ions are generated in the electrode space, and act on the surface of the soot particles passing through the electrostatic field. Under the action of the electric field force, they move towards the electrodes with opposite polarities and are deposited on the electrodes.

[0018] Further improvement based on the above technical solution is that the vibration - knocking assembly includes a screw rod and a sliding rod installed in parallel inside the filter box, and a moving block penetrates through the screw rod and the sliding rod. A driving motor for driving the screw rod to rotate is installed inside the filter box, and the screw rod is in threaded transmission connection with the moving block. A reset vibration spring is fixedly installed at one end of the moving block adjacent to the electrostatic precipitator, and an insulating knocking rod is fixedly installed at the end of the reset vibration spring. The insulating knocking rod is used to vibrate - knock the discharge electrode and the collecting electrode respectively through its movable displacement, so that the soot particles deposited on their surfaces fall to the bottom of the filter box.

[0019] Further improvement based on the above technical solution is that the filter element includes a rectangular mounting frame, which is embedded and installed inside the windshield inner frame body. Filter through - openings are respectively provided on the front, rear, left, right, and upper sides of the rectangular mounting frame, and activated carbon filter plates are installed in each of the filter through - openings. When the soot passes through the side air vents on four sides, it can be respectively subjected to the third - stage filtering by the activated carbon filter plates on four sides, and then passes through the activated carbon filter plate on the upper side of the rectangular mounting frame for the fourth - stage filtering, and finally is conveyed upward into the air duct.

[0020] Further improvement based on the above technical solution is that longitudinal vehicle frames are connected to the first longitudinal track and the second longitudinal track for rolling back and forth. The first longitudinal track, the second longitudinal track, and the third longitudinal track are respectively provided with guide rails corresponding to the transverse track, and the longitudinal vehicle frames of the first longitudinal track or the second longitudinal track are sent into the third longitudinal track by using the guide rails. The third longitudinal track is arranged inside the lower movable vehicle groove. A placement table for placing forging materials is arranged on the upper side of the longitudinal vehicle frame in a lifting manner, and a lifter is installed between the longitudinal vehicle frame and the placement table for lifting and jacking up the placement table. Sealing convex edges are arranged on four sides of the placement table. When the placement table is lifted upward, the sealing convex edges can be tightly pressed against the lower edge of the upper heating cavity for sealing. A hinged door is rotatably connected to the front side of the upper heating cavity, and the hinged door is locked to the front side of the heating furnace body by using a locking device.

[0021] By adopting the above technical solution, the present invention has the following advantages:

[0022] 1. The structure of the present invention is compact and ingenious. By installing a water-cooled filtering pyramid cylinder on the upper side of the heating furnace body, under the heat flow of the heating furnace body itself and the air extraction effect of the air duct, the flue gas can quickly enter the water-cooled filtering pyramid cylinder. The frustum-shaped smoke collecting cylinder installed in the water-cooled filtering cavity is used to centrally transport high-temperature soot, so that most of the heat can be conducted to the frustum-shaped smoke collecting cylinder and the spraying assembly. The spraying assembly sprays a circular water curtain downward to cool down the frustum-shaped smoke collecting cylinder body. At the same time, under the soaking of the filtered water in the water-cooled filtering cavity, the frustum-shaped smoke collecting cylinder and the water-cooled filtering pyramid cylinder body can also be cooled down. At the same time, when the spraying assembly sprays a circular water curtain downward, it can also cool down the soot blown out by the frustum-shaped smoke collecting cylinder and play a role of primary water flow dust settling and filtering;

[0023] At the same time, a plurality of nozzles are installed in an annular array at the bottom of the annular pipe of the spraying assembly, so that the water flow sprayed downward by the nozzles flows downward along the inclined surface of the frustum-shaped flow guiding cap, and the formed water curtain cavity can surround the upper side of the frustum-shaped smoke collecting cylinder. When the soot is discharged from the lower side of the frustum-shaped flow guiding cap, it can fully contact the water flow. And the inverted cone-shaped flow dividing part arranged on the inner side of the frustum-shaped flow guiding cap facing the frustum-shaped smoke collecting cylinder can disperse the soot to four sides and respectively disperse it evenly to the water curtain by the air flow dispersion net, avoiding the over-concentration of the soot, further improving the contact between the soot and the water curtain, and thus promoting the cooling and filtering effects;

[0024] 2. A water purifier is also provided, which can extract and purify the filtered water in the water-cooled filtering cavity and avoid the excessive water level in the water-cooled filtering cavity. The output end of the water purifier is connected to the cooling tower to cool the water again, and then re-transport it to the water storage cavity for storage, forming a complete water-cooled filtering cycle, which is energy-saving and environmentally friendly;

[0025] 3. A multi-directional filter box is embedded in the installation notch on the upper side of the water-cooled filtering pyramid cylinder. The multi-directional filter box can be quickly disassembled and assembled by pulling the hand-held grip rod, which is beneficial to the later replacement speed. The multi-directional filter box is mainly sleeved on the lower plug-in pipe embedded in the middle of the installation notch through the upper plug-in pipe. While improving the connection stability, the lower plug-in pipe is connected to the inside of the multi-directional filter box. Since filter boxes are respectively embedded on the four sides of the multi-directional filter box, the soot after primary filtration can be further dispersed, and the soot particles are deposited and adsorbed under the action of the electrostatic field force of the electrostatic precipitator in the four filter boxes, achieving secondary dispersion and purification of the soot;

[0026] Among them, the vibration knocking assembly can quickly knock down the dust impurities deposited by the electrostatic precipitator to the grooves at the bottom of the filter box for centralized collection. Later, when cleaning these waste materials, the filter box can be quickly cleaned or replaced by removing the filter box, which is simple and convenient to use;

[0027] 4. After the secondary filtration and purification of the flue gas, it can enter the filter element installed at the top of the multi-directional filter box through the side air vents for the third and fourth filtration and purification. The filter element is mainly installed with activated carbon filter plates at the filter openings on the four sides and the top of the rectangular mounting frame. The activated carbon filter plates on the four sides respectively conduct the third filtration and purification. When the activated carbon filter plates on the four sides filter dust and impurities, the electric field force of the electrostatic precipitator can deposit the dust and impurities filtered outside the activated carbon filter plates on the four sides, ensuring the use efficiency of the activated carbon filter plates on the four sides and the purification effect on the soot. The activated carbon filter plate at the top filter opening serves as the last step of soot filtration, which can ensure the further purification of the flue gas filtered by the activated carbon filter plates on the four sides, greatly improving the overall purification effect of the water-cooled filtration pyramid cylinder. Moreover, the entire filter element can be quickly disassembled and assembled, and can be replaced separately according to the later use requirements.

[0028] 5. By setting the first longitudinal track, the second longitudinal track, and the third longitudinal track to cooperate with the transverse track, the longitudinal vehicle frames on the first longitudinal track, the second longitudinal track, and the third longitudinal track can be alternately transported through the transverse vehicle frame on the transverse track. In this way, when the materials loaded on the placement table of the longitudinal vehicle frame on the upper side of the third longitudinal track are sent into the heating furnace body for heating and forging, the transverse vehicle frames on the first longitudinal track or the second longitudinal track can simultaneously load and unload materials, which is beneficial to improving the work efficiency.

Detailed implementation manners

[0045] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0046] As Figures 1-14As shown in the figure, the present invention provides a technical solution for a trolley-type forging heating furnace for soot purification, including a transverse track 1, a transverse vehicle frame 2 rolling on the upper side of the transverse track 1, a first longitudinal track 31, a second longitudinal track 32 and a third longitudinal track 33 vertically arranged at the rear side of the transverse track 1, and a heating furnace body 5 arranged directly above the third longitudinal track 33. The first longitudinal track 31 and the second longitudinal track 32 are both connected with longitudinal vehicle frames 34 in a front-back rolling manner. The first longitudinal track 31, the second longitudinal track 32 and the third longitudinal track 33 are all provided with guide rails 4 corresponding to the transverse track 1, and the longitudinal vehicle frame 34 of the first longitudinal track 31 or the second longitudinal track 32 is sent into the third longitudinal track 33 by using the guide rail 4. The third longitudinal track 33 is arranged inside the lower movable car slot 51. For example, after the materials are assembled on the longitudinal vehicle frame 34 on the first longitudinal track 31, they can be transported to the transverse vehicle frame 2 on the upper side of the transverse track 1 through the guide rail 4. Then, the longitudinal vehicle frame 34 is transported to the front side of the third longitudinal track 33 by using the transverse vehicle frame 2 and sent to the upper side of the third longitudinal track 33. At this time, the longitudinal vehicle frame 34 equipped with materials is processed inside the lower heating furnace body 5, and the alternate transportation of the longitudinal vehicle frame 34 can be realized. While the materials on the longitudinal vehicle frame 34 on the third longitudinal track 33 are being processed, the longitudinal vehicle frame 34 on the outer second longitudinal track 32 can perform synchronous loading and unloading work, which can greatly improve the transportation efficiency. A placement table 341 for placing forging materials is arranged on the upper side of the longitudinal vehicle frame 34 in a lifting manner, and a lifter 35 is installed between the longitudinal vehicle frame 34 and the placement table 341 for lifting and jacking up the placement table 341. The lifter 35 is a lifting mechanism in the prior art, as long as it can lift the placement table 341. Closed convex edges 342 are arranged on the four sides of the placement table 341. When the placement table 341 is lifted upward, the closed convex edges 342 can be tightly pressed against the lower side edge of the upper heating cavity 52 for sealing. A hinged door 53 is rotatably connected to the front side of the upper heating cavity 52, and the hinged door 53 is locked to the front side of the heating furnace body 5 by using a locking device 531. The locking device 531 is a door lock mechanism in the prior art, as long as the hinged door 53 can be locked firmly.

[0047] In this embodiment, the heating furnace body 5 is sequentially provided with a lower movable car slot 51 and an upper heating cavity 52 from bottom to top, and four flue gas through holes 54 are communicated with the heating furnace body 5 at the top of the upper heating cavity 52 for discharging flue gas upward. A water-cooled filter pyramid cylinder 6 is installed on the top of the heating furnace body 5. Four frustum-shaped smoke collecting cylinders 60 are integrally arranged at the bottom of the water-cooled filter pyramid cylinder 6 and are communicated with the flue gas through holes 54 through the frustum-shaped smoke collecting cylinders 60, so that soot can enter the water-cooled filter pyramid cylinder 6 through the four frustum-shaped smoke collecting cylinders 60 respectively. Moreover, an air duct 7 is installed on the top of the water-cooled filter pyramid cylinder 6, and a fan 71 is installed at the end of the air duct 7. When the fan 71 sucks air, a negative pressure is generated inside the water-cooled filter pyramid cylinder 6 to increase the flow rate of the soot.

[0048] The inner side of the water-cooled filter pyramid cylinder 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 fume collecting tube 60 can guide the water liquid and fully contact the water liquid because the fume collecting tube 60 is an inclined surface, which can play a role in cooling the flow of the fume collecting tube 60. In addition, the annular downward flowing water curtain can filter the smoke blown out of the fume collecting tube 60. In addition, since the fume collecting tube 60 is a fume collecting tube with a wide bottom and a narrow top, it is used to collect and pressurize the smoke generated by the heating furnace body 5, so that the heat is concentrated on the fume 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 fume collecting tube 60 guides and collects the water sprayed by the spray assembly 66 to the water-cooling filter chamber 61. The water gathered at the bottom of the water-cooling filter chamber 61 again immerses and cools the outer side of the fume collecting tube 60, and can reduce the conduction heat of the water-cooling filter pyramid 6 in contact with the heating furnace body 5, thereby reducing the influence of high temperature on the use.

[0049] A multi-directional filter box 67 is embedded in the embedded installation slot 64 on the upper side of the water-cooled filter pyramid cylinder 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 performing secondary, tertiary and quadruple filtering of smoke and dust. Specifically, the multi-directional filter box 67 includes a hollow frame 670, and ventilation slots 671 are respectively opened on the upper, lower, front, rear, left and right sides of the hollow frame 670, wherein an upper plug-in pipe 672 is fixedly arranged 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.

[0050] Filter boxes 676 are respectively and hermetically and embeddedly installed in the ventilation slots 671 on the front, rear, left and right sides. A box opening 6761 communicating with the ventilation slot 671 is provided on one side of each filter box 676. Each filter box 676 is relatively independent. When a certain 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, improving the reliability and flexibility of the entire filtration system;

[0051] An electrostatic precipitator 677 is installed inside the filter box 676. When the soot enters the multi-directional filter box 67 through the lower plug-in pipe 63 and the upper plug-in pipe 672, since the wind-blocking inner frame 673 inside the upper ventilation slot 671 disperses the soot gas to the ventilation slots 671 on all four sides, the soot can enter each filter box 676 evenly. Inside the filter box 676, the electrostatic precipitator 677 performs secondary filtration and dust removal on the soot. The electrostatic precipitator 677 includes a plurality of discharge electrodes 6771 and collecting electrodes 6772 arranged vertically adjacent to each other. The electrostatic precipitator 677 inputs high-voltage direct current between the two levels of the discharge electrode 6771 and the collecting electrode 6772 to generate cations and anions in the electrode space. The soot particles move towards the opposite electrodes under the action of the electric field force and deposit, effectively removing the particulate matter in the soot and greatly improving the purification degree of the soot.

[0052] Moreover, the vibration component arranged inside the filter box 676 can regularly vibrate and knock the electrostatic precipitator 677. The vibration component drives the screw rod 681 to rotate through the driving motor 686, so that the moving block 683 moves under the guidance of the screw rod 681 and the slide rod 682, and the discharge electrode 6771 and the collecting electrode 6772 are respectively knocked by the reset vibration spring 684 and the insulating knocking rod 685. In this way, the dust impurities deposited on the electrodes will fall to the bottom of the filter box 676 for collection, avoiding the excessive accumulation of dust on the electrodes from affecting the filtering effect of the electrostatic precipitator 677, and at the same time facilitating the centralized treatment of the dust impurities.

[0053] In this embodiment, side air vents 6731 corresponding to and communicating with the box opening 6761 are provided on the four sides of the wind shield inner frame 673. A filter element 674 is embedded and installed inside the wind shield inner frame 673. The filter element 674 includes a rectangular mounting frame 6741, which is embedded and installed inside the wind shield inner frame 673, making the installation of the filter element 674 in the multi-directional filter box 67 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, thus ensuring the stable progress of the filtration process and being relatively convenient for disassembly and assembly in the later stage. Filter through-holes 6742 are respectively provided on the front, rear, left, right, and upper sides of the rectangular mounting frame 6741, and activated carbon filter plates 6743 are installed in each of the filter through-holes 6742. When the soot passes through the side air vents 6731 on the four sides, it can be respectively filtered for the third time by the activated carbon filter plates 6743 on the four sides. This all-round filtration design can capture the impurities in the soot more comprehensively, avoiding the dead corners or blockages that may exist in single-direction filtration, and improving the filtration efficiency and purification effect of the entire filter element 674 on the soot; then it is filtered for the fourth time by the activated carbon filter plate 6743 on the upper side of the rectangular mounting frame 6741 and finally conveyed upward into the air duct 7. That is to say, when the soot after secondary filtration enters the filter element 674 through the box opening 6761 and the side air vents 6731, the activated carbon filter plates 6743 on the four sides of the rectangular mounting frame 6741 start to play a role. The activated carbon filter plates 6743 have a rich pore structure and can adsorb impurities such as fine particles and harmful gases in the soot. By respectively filtering for the third time by the activated carbon filter plates 6743 on the four sides, the purification degree of the soot is further improved, and the harmful substances remaining after secondary filtration are removed; after being filtered three times by the activated carbon filter plates 6743 on the four sides, the soot continues to pass upward through the activated carbon filter plate 6743 on the upper side of the rectangular mounting frame 6741 for the fourth time. This filtration process, as the last guarantee, can intercept extremely fine particles or harmful substances that may have been missed before, ensuring that the soot finally conveyed upward into the air duct 7 meets a high purification standard and greatly reducing the soot pollutants discharged into the environment.

[0054] In the above technical solution, a waste baffle 6762 is provided at the box opening 6761 and is flush with the upper insertion pipe 672 in height, 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 downward into the groove at the bottom of the filter box 676 for centralized collection, effectively preventing the dust from scattering everywhere in the filter box 676, facilitating the subsequent cleaning and treatment of the dust. Moreover, 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 soot particles, but also promotes the dust impurities filtered by the four-sided activated carbon filter plate 6743 to fall downward into 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 soot purification and dust collection.

[0055] In this embodiment, it further includes a water purifier 8 and a water cooling tower. The water pump inlet end of the water purifier 8 is connected to the bottom of the water cooling filtration chamber 61 through a water pipe for filtering the sprayed and precipitated water. The water outlet end of the water purifier 8 is connected to the water cooling tower through a water pipe. The water cooling tower cools the water and then reconnects it to the inner side of the water storage chamber 62 to form a water cooling filtration cycle, ensuring that there is always an appropriate amount of water in the water cooling filtration chamber 61 for the spraying assembly 66 to cool and filter the soot. The stable water supply helps to maintain the stable operation of the entire soot purification system, ensuring that each link, such as the cooling of the frustum-shaped smoke collecting cylinder 60 and the water curtain filtration of the soot, can be continuously and effectively carried out. An injection port 621 is provided on the upper side of the water storage chamber 62. When the water volume decreases due to reasons such as water evaporation during the operation of the system, water can be conveniently replenished through the injection port 621. At the same time, this injection port 621 also provides convenience for operations such as system debugging and cleaning. For example, when the system is initially operated or restarted after maintenance, the water volume in the water storage chamber 62 can be adjusted to an appropriate level through the injection port 621.

[0056] 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.

[0057] 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.

[0058] The specific working principle includes the following steps:

[0059] Transportation of materials: 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 vehicle frames 34 on the first longitudinal track 31, the second longitudinal track 32, and the third longitudinal track 33 can be alternately transported through the transverse vehicle frame 2 on the transverse track 1. In this way, when the materials loaded on the placement table 341 of the longitudinal vehicle frame 34 on the upper side of the third longitudinal track 33 are sent into the heating furnace body 5 for heating and forging, the transverse vehicle frame 2 on the first longitudinal track 31 or the second longitudinal track 32 can simultaneously load and unload materials, enabling the loading / unloading process and the heating process to be carried out simultaneously, which can improve the overall working efficiency. Moreover, the third longitudinal track 33 is located in the lower movable chute 51 on the lower side of the heating furnace body 5. The longitudinal vehicle frame 34 drives the placement table 341 to lift and lower through the elevator 35. The four sides of the placement table 341 are provided with closed convex edges 342. After being lifted, it seals with the lower edge of the upper heating cavity 52. Then, the hinged door 53 is closed and locked with the lock 531 to make the heating furnace body 5 form a sealed space to prevent heat from escaping;

[0060] Smoke and dust cooling and primary purification process: The smoke and dust generated when the heating furnace body 5 works enters the water-cooled filter frustum 6 through the flue gas through-hole 54. Due to the air extraction by the fan 71, a negative pressure is generated in the water-cooled filter frustum 6, accelerating the flow of smoke and dust. The spray assembly 66 pumps out the water in the water storage cavity 62 and sprays it downward through the nozzles 664 of the annular pipe 663. Under the guiding action of the inclined surface of the frustum-shaped flow guiding cap 661, an annular water curtain is formed. In the water-cooled filter cavity 61, since the diameter of the frustum-shaped smoke collecting cylinder 60 decreases from bottom to top, the heat can be concentrated on the frustum-shaped smoke collecting cylinder 60 and the spray assembly 66. And the smoke blown out by the frustum-shaped flow guiding cap 661 towards the inverted conical flow dividing member 6612 can flow dispersedly to the four sides and respectively pass through the air flow dispersing net 662 and evenly disperse towards the water curtain wall, avoiding the over-concentration of the smoke and dust pressure and affecting the flow of the water curtain, further improving the contact and dust settling of the smoke and dust with the water curtain wall, thereby promoting the filtering and cooling effects of the smoke and dust, as well as the cooling effect of the flue gas and the fittings. This can effectively cool down the frustum-shaped smoke collecting cylinder 60 itself. At the same time, under the soaking of the filtered water in the water-cooled filter cavity 61, the frustum-shaped smoke collecting cylinder 60 and the water-cooled filter frustum 6 itself can also be cooled down, improving the service life;

[0061] Water-cooled filtration circulation system: The dust and impurities dust-settled and filtered by the water curtain will fall into the water-cooled filter cavity 61. By setting the water purifier 8, the filtered water in the water-cooled filter cavity 61 can be pumped out and purified, and the water level in the water-cooled filter cavity 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 cavity 62 for storage, forming a complete water-cooled filtration cycle, realizing the recycling of water resources, promoting the cooling and filtering effects, saving water resources, and reducing wastewater discharge;

[0062] Secondary filtration and purification of soot: The soot that has undergone the above-mentioned primary filtration and purification enters the lower insertion pipe 63 through each through-port 651, and enters the upper insertion pipe 672 of the multi-directional filter box 67 from the lower insertion pipe 63. Blocked by the bottom of the wind-blocking inner frame 673, the soot 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. When high-voltage direct current is input between the discharge electrode 6771 and the precipitation electrode 6772, cations and anions are generated in the electrode space, and act on the surface of the soot particles passing through the electrostatic field. Under the action of the electric field force, they move towards the electrodes with opposite polarities and are deposited on the electrodes, achieving secondary filtration and purification of the soot. After a certain period of time, the vibration component works. The driving motor 686 drives the screw 681 to rotate. The screw 681 drives the moving block 683 to move along the discharge electrode 6771 and the precipitation electrode 6772 through screw thread transmission. The insulating knocking rod 685 connected to the moving block 683 through the reset vibration spring 684 knocks on the discharge electrode 6771 and the precipitation electrode 6772, causing the deposited dust impurities to quickly fall to the groove at the bottom of the filter box 676 for centralized collection. And in the later stage, when cleaning these waste materials, the filter box 676 can be removed to quickly clean or replace the filter box 676, improving the efficiency and convenience of later maintenance and use;

[0063] Tertiary and quaternary high-efficiency filtration and purification of soot: After the secondary filtration and purification of the flue gas, it can enter the filter element 674 embedded and installed at the top of the multi-directional filter box 67 through the side air outlet 6731 for tertiary and quaternary filtration and purification. The filter element 674 is mainly installed with activated carbon filter plates 6743 at the four sides and the top of the rectangular mounting frame 6741. The activated carbon filter plates 6743 on the four sides respectively carry out the third filtration and purification. 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 outside the activated carbon filter plates 6743 on the four sides, ensuring the use efficiency of the activated carbon filter plates 6743 on the four sides and the purification effect on the soot. The activated carbon filter plate 6743 at the top filter through-port 6742 serves as the last step of soot filtration, which can ensure the further purification of the flue gas filtered by the activated carbon filter plates 6743 on the four sides, thus greatly improving the overall purification effect of the water-cooled filtration pyramid cylinder 6. Finally, it is discharged to the outside through the air duct 7 and the fan 71, or connected to the next purification process. Through multiple filtrations and coolings, harmful substances and impurities in the soot can be effectively removed, greatly improving the purification effect and reducing environmental pollution. Moreover, the entire filter element 674 can also be quickly disassembled and assembled, facilitating later cleaning and replacement, and reducing the maintenance cost.
