Description

Technical Field

[0001] The invention relates to the field of tubular heating furnaces, and more particularly to a cooling circulation heating furnace. Background Art

[0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces to the rolling and forging temperature. Heating furnaces are used in many industries such as petroleum, chemical industry, and metallurgy. The heating furnaces used include tubular heating furnaces. Tubular heating furnaces are process heating furnaces used in industries such as petroleum refining. The heated material flows in the tube with a gas or liquid as the medium. The heating method is direct fire. The exhaust temperature of the tubular heating furnace can be reduced to about 100°C, achieving partial condensation of acidic water vapor in the flue gas.

[0003] When the existing tubular heating furnace is not in use, the furnace body is generally cooled by natural cooling, resulting in low furnace cooling efficiency. When the staff is close to the furnace body for management, burns are very likely to occur.

[0004] A Chinese patent application with publication number CN211651208U discloses a tubular heating furnace for crude oil production, which includes a main body, an alarm light, a smoke exhaust pipe, a water pump, an oil inlet pipe, an oil outlet pipe, a support leg, a connecting pipe, a cooling water tank, and a drain pipe. The cooling pipe is wrapped around the main body in a spring shape to increase the cooling area of ​​the main body by the cooling pipe, and then the water in the cooling pipe is used to absorb heat from the heating furnace, so that the water with a lower temperature can remain in a heat-absorbing state, thereby maximizing the reduction of the heat emitted by the heating furnace and preventing workers from getting close to the heating furnace and getting burned.

[0005] In view of the above problems, the existing patents provide solutions, but the degree of interaction between the cooling pipes and the conduits used for processing in the furnace body is not high, and the heat from the outer surface of the furnace body can only be dissipated, making it difficult to quickly cool down the entire furnace body, and the heated materials cannot be effectively cooled. In addition, the cooling water tank provided cannot perform secondary cooling of the cooling water that has already absorbed heat, making it difficult to further improve the overall heat dissipation efficiency of the furnace body.

[0006] Therefore, a cooling circulation type heating furnace is proposed. Summary of the invention

[0025] Furthermore, a corresponding cover that can be turned away is provided at the bottom of the heat-insulating sleeve.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) Through the separation design of the cooling circulation mechanism inside the tubular heating furnace body, the inner furnace used for heating is divided into two layers, and the corresponding inner and outer heating tubes and their cooling disc-type ducts are connected correspondingly through an 8-type heat-conducting frame. When the furnace body needs to be cooled, reverse cooling water can be introduced through the cooling water supply circulation mechanism, which can not only take away the heat of the furnace body, but also increase the heat taken away from the internal heating tube, effectively solving the problem of the prior art that the interaction between the cooling tube and the duct used for processing in the furnace body is not high, and can only dissipate the heat from the outer surface of the furnace body.

[0028] (2) Through the cooperation of the first auxiliary cooling mechanism and the second auxiliary cooling mechanism, during the reverse heat dissipation process of the cooling disc-type duct of the cooling circulation mechanism, the second servo motor and the vacuum pump can control the air guide mechanism on the outside to blow and suck air, thereby dissipating heat to the outer surface of the furnace wall tube with slots and the cooling disc-type duct at the same time, and more efficiently removing the heat from the furnace body. At the same time, the rotating blowing can effectively cover every part inside the tubular heating furnace body, further improving the cooling circulation capacity of the cooling circulation mechanism.

[0029] (3) By utilizing the blowing and suction functions of the air guide mechanism, not only can the internal movable fan blades be used to blow air to dissipate heat, but the second hose can also be used to extract heat to the chimney. Furthermore, through the driving action of the first screw at the output end of the third servo motor, the U-shaped bracket can be controlled to drive the brush block to brush dust up and down, thereby avoiding the problem of the heat dissipation holes being blocked due to long-term lack of maintenance.

[0030] (4) The U-shaped bracket controlled by the output end of the first servo motor in the cooling water supply circulation mechanism can stir the cooling water that has been used once and is circulating inside, and can effectively discharge the heat absorbed by it through the frame with heat dissipation outlet in cooperation with a powerful fan, so that the cooling water that is reused can be further cooled, thereby improving the efficiency of the overall cooling cycle and effectively solving the problem that the cooling water tank set in the prior art cannot perform secondary cooling on the cooling water that has already absorbed heat.

[0031] (5) The wind control mechanism installed inside the cooling water supply circulation mechanism can control the blowing direction of the powerful fan, so that the wind used for heat dissipation inside can be flexibly adjusted, that is, it can blow the cooling water directly downward at a 45-degree angle, and can also dissipate heat to the rotating heat dissipation fins, further improving the effect of secondary cooling of the cooling water.

[0032] (6) The frame with heat dissipation port set by the cooling water supply circulation mechanism can dissipate heat outwards. At the same time, with the bill action of the second screw at the output end of the fourth servo motor, the sealing cloth can be driven to seal the heat dissipation port when the powerful fan is not working, thereby preventing external debris and dust from entering the interior and affecting the quality of the internal cooling water.

[0063] like Figure 5 , Figure 7 As shown, a second auxiliary cooling mechanism 12 is also installed on the outside of the cooling circulation mechanism 5, and the second auxiliary cooling mechanism 12 includes an annular cover plate 121 fixedly installed on the outside of the tubular heating furnace body 1, and a double-layer cover 122 is movably sleeved on the outside of the annular cover plate 121, and a plurality of wing plates 124 corresponding to the upper and lower parts of the air guide mechanism 112 are fixedly installed on the upper inner wall of the double-layer cover 122, and sleeve rods 125 corresponding to the upper and lower parts of the air guide mechanism 112 are fixedly installed on the bottom of the wing plates 124, and a plurality of interconnected and identical air outlets 123 are arranged in a circle on the outer surfaces of the annular cover plate 121 and the double-layer cover 122.

[0066] By adopting the above technical solution, the problem that the cooling pipes provided in the prior art have a low degree of interaction with the pipes used for processing in the furnace body and can only dissipate the heat on the outer surface of the furnace body is solved. First, according to the working coordination of each mechanism, the pipe corresponding to the input material is connected to the outer side of the third external sleeve 7, and the corresponding discharge pipe is installed and connected to the fourth external sleeve 8, so that the flowing medium entering the pipe passes through the convection chamber 2 and is heated by the tubular heating furnace body 1. At the same time, the first external sleeve 55 and the second external sleeve 56 on both sides of the cooling disc pipe 53 are connected to the box 101 of the cooling water supply circulation mechanism 10 by using the first hose 57, so that the incoming cooling water is circulated and transported, and then connected to the outer side of the first branch pipe 118. The second hose 18 communicated with the chimney 3 outputs heat to a higher place, and is connected to the existing gas conduit on the outside of the second pipe port 15 for subsequent gas supply to the flame-spraying horizontal block 9. At the beginning of the operation, the flowing medium enters the interior of the tubular heating furnace body 1 through the heating pipe 6, and is heated by the direct flame-spraying action of the flame-spraying horizontal block 9. When the flowing medium reaches a suitable temperature, it can be output through the fourth external sleeve 8. When the hot furnace body is cooled, cooling water is transported to the cooling disc conduit 53 of the cooling circulation mechanism 5 through the cooling water supply circulation mechanism 10 and the first hose 57. The direction of the input cooling water is opposite to that of the flowing medium. The heating pipe 6 can be directly cooled under the thermal conductivity of the 8-type heat-conducting frame 52. At the same time, due to the 8-type heat-conducting The fitting effect of the frame 52 and the furnace wall tube 51 with slots can also cool down the innermost wall side of the tubular heating furnace body 1, and further start the first auxiliary cooling mechanism 11 and the second auxiliary cooling mechanism 12. Under the suction effect of the suction pump 117, each air guide mechanism 112 on the upper side of the cavity ring 111 is controlled to be exhausted through the second branch pipe 119. When the adsorbed gas of the suction pump 117 enters the rectangular air guide shell 1121 of the air guide mechanism 112, it can drive the fan blades 1124 on the outer surface of the ball rod 1123 to rotate in turn, take away the heat from the furnace wall tube 51 with slots and the outside of the cooling disc guide 53, and discharge it through the first branch pipe 118 and the second hose 18 through the chimney 3, and at the same time start the second servo motor 113 to output The bent support plate 115 at the outlet end rotates along the first arc groove 114, driving the cavity ring 111 to rotate synchronously along the second arc groove 116, so that the air guide mechanism 112 can rotate, and the gas used for heat dissipation covers every part of the furnace wall tube 51 with slots. At the same time, the rotating air guide mechanism 112 can drive the double-layer cover 122 to move synchronously on the outside of the circular cover plate 121, and control the movement of the air outlet 123 on both sides of the inside and outside, so as to open the second auxiliary cooling mechanism 12, so that all the openings on the outside of the cooling circulation mechanism 5 are opened, and with the rotation of the fan blades 1124 in the air guide mechanism 112, the heat can be directly output to the outside through the filter screen 1122 arranged on the rear side of the rectangular air guide shell 1121, so as to quickly discharge the heat of the hot furnace body.The invention effectively solves the problem that the cooling pipe provided in the prior art has a low interaction with the pipe used for processing in the furnace body, and can only dissipate the heat on the outer surface of the furnace body.

[0075] By adopting the above technical scheme, the problem that the cooling water tank set in the prior art cannot perform secondary cooling of the cooling water that has absorbed heat is solved. First, cooling water is added to the interior of the storage box 102 through the third pipe port 16 installed on the outside of the box body 101. The cooling water is transported to the interior of the cooling disc duct 53 through the first hose 57 installed on the outside of the fourth pipe port 17 on both sides, and circulates. When the cooling water enters the interior of the box body 101 for the second time, the powerful fan 109 and the first servo motor 105 are started. Through the rotation of the circular shaft frame 104 at the output end of the first servo motor 105, the heat dissipation fin plate 107 on the outside of the U-shaped bracket 106 can be driven to rotate at 90 degree intervals and rotate into the interior of the box body 101 in turn. The heat dissipation efficiency of the internal cooling water can be increased by stirring. At the same time, the strong blowing effect of the powerful fan 109 is used to output the heat generated by stirring from the opening of the frame 1010 with the heat dissipation port. Moreover, the powerful fan 109 is controlled by the wind control mechanism 19, and the automatic telescopic rod 195 of the powerful fan 109 is automatically adjusted. The dynamic telescopic effect can drive the partition 197 to rotate around the circular shaft block 191 through the activities of the limit sleeve shaft frame 196 and the circular shaft head 194 at both ends, and flexibly adjust the wind blown out by the powerful fan 109, which can be tilted and directly aligned with the cooling water inside the storage box 102 for heat dissipation, and can also be aligned with the heat dissipation fins 107 for heat dissipation, further improving the heat dissipation efficiency of the cooling water supply circulation mechanism 10 for cooling water, and simultaneously improving the overall heat dissipation efficiency of the cooling circulation mechanism 5, effectively solving the problem that the cooling water tank set in the prior art cannot perform secondary cooling of the cooling water that has absorbed heat. At the same time, further during the non-working process of the cooling water supply circulation mechanism 10 or the non-working process of the powerful fan 109, the rotation of the second screw 22 at the output end of the fourth servo motor 20 can drive the nut sleeve 24 to move downward along the round rod 23 and the lifting slot frame 21, pull the sealing cloth 25 downward for sealing, and directly close the heat dissipation holes of the heat dissipation port frame 1010 to prevent external dust from entering the interior of the storage box 102 without the action of wind.

[0076] Working principle: First, assemble the corresponding conduits according to the working coordination of each mechanism. At the beginning of the work, the flowing medium enters the interior of the tubular heating furnace body 1 through the heating tube 6, and is heated under the direct flame action of the flame-spraying horizontal block 9. When the flowing medium enters the appropriate temperature, it can be output through the fourth external sleeve 8. When the hot furnace body is cooled, the cooling water is transported to the cooling disc conduit 53 of the cooling circulation mechanism 5 through the cooling water supply circulation mechanism 10 and the first hose 57. Under the heat conduction effect of the 8-type heat-conducting frame 52, the heating tube 6 can be directly cooled. At the same time, due to the adhesion between the 8-type heat-conducting frame 52 and the furnace wall tube 51 with slots, the tubular heating The innermost wall side of the furnace body 1 is cooled, and then the first auxiliary cooling mechanism 11 and the second auxiliary cooling mechanism 12 are started. Through the suction action of the vacuum pump 117, the gas used for heat dissipation is covered to every part of the furnace wall tube 51 with slots through the rotating air guide mechanism 112 for heat dissipation. The cooling water after heat dissipation enters the interior of the storage box 102 again, and the powerful fan 109 and the first servo motor 105 are started. The automatic telescopic action of the automatic telescopic rod 195 is used to control the wind control mechanism 19 to flexibly adjust the wind blown out by the powerful fan 109, so that it can be tilted and directly aimed at the cooling water inside the storage box 102 for heat dissipation, and can also be aimed at the heat dissipation fin plate 107 for heat dissipation.
