Description

Technical Field

[0001] The utility model belongs to the technical field of cracking furnace feeding equipment, and in particular relates to a cracking furnace material distribution feeding device with double cracking tubes. Background Art

[0002] Organic solid waste refers to solid and semi-solid wastes containing organic matter generated in the process of industrial and agricultural production, oily sludge in the petrochemical industry, biomass in agriculture and forestry, domestic garbage generated in cities, etc. The quantity is very huge and the pollution is serious.

[0003] The existing organic solid waste treatment technology often uses a cracking furnace to perform cracking heat treatment on solid waste. Solid waste (such as waste tires) is cracked in the cracking tube. The existing cracking furnace usually has only one cracking tube, which has low treatment efficiency; and the cracking tubes of each cracking furnace usually have corresponding feeding ports. When it is necessary to feed into two cracking tubes, the organic solid waste needs to be put into the cracking tubes of the corresponding cracking furnaces respectively, which reduces the feeding efficiency of the organic solid waste. In addition, the amount of solid waste put into the two cracking tubes is prone to large deviations, and it is easy for one cracking tube to have a large waste content, while the other cracking tube has no material and runs at no load, which is not conducive to ensuring the cracking efficiency of the entire cracking furnace system. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the utility model provides a double cracking tube cracking furnace material distribution and feeding device, which increases the cracking efficiency of the cracking furnace by installing two cracking tubes in the cracking furnace. The two cracking tubes use the same feeding storage box to ensure that the content of solid waste in the two cracking tubes is basically the same, thereby ensuring the cracking quality of the cracking furnace.

[0005] The utility model is realized by the following technical solutions:

[0006] A splitting and feeding device for a cracking furnace with double cracking tubes is installed at the front end of the cracking furnace. Two cracking tubes are installed in the cracking furnace. A vertically arranged feeding pipe is arranged above each cracking tube. The splitting and feeding device comprises a feeding storage box, a mixing pipe and a splitting mechanism. A storage space for accommodating solid waste is arranged in the feeding storage box, and a feeding port is arranged above the storage space. The mixing pipe is arranged vertically below the feeding storage box, and the mixing pipe is connected to the storage space. A horizontally arranged breaking and stirring roller is arranged in the mixing pipe. The splitting mechanism comprises a splitting pipe, a first spiral conveying device and a second spiral conveying device arranged inside the splitting pipe. A feeding port connected to the mixing pipe is arranged in the middle of the splitting pipe, and a discharge port connected to the feeding pipe is arranged at both ends of the splitting pipe.

[0007] Furthermore, a collecting barrel is provided at the connection between the mixing pipe and the feeding storage box. In the vertical downward direction, the width of the collecting barrel gradually decreases to be consistent with the width of the mixing pipe, so as to facilitate the solid waste in the storage space to flow to the mixing pipe.

[0008] Furthermore, two feeding regulators are installed in the collecting barrel, and the feeding regulator includes a baffle plate, a driving bolt and a threaded sleeve. The baffle plate is hinged to the connection between the collecting barrel and the feeding storage box, the driving bolt is hinged to the side of the baffle plate away from the feeding storage box, the threaded sleeve is fixed to the outer wall of the collecting barrel, and the collecting barrel is provided with a through hole aligned with the internal space of the threaded sleeve. The driving bolt passes through the through hole and the threaded sleeve and is threadedly connected to the threaded sleeve, so as to adjust the flow rate of solid waste in the storage space to the mixing pipe.

[0009] Furthermore, a Teflon coating is sprayed on the upper part of the baffle plate. The baffle plate sprayed with the Teflon coating has the advantages of corrosion resistance, wear resistance, non-deformation, lubrication and non-stick, high temperature resistance, and low friction coefficient.

[0010] Furthermore, the first screw conveying device and the second screw conveying device share a driving shaft, a driving motor is installed on one side of the driving shaft to provide power support for the rotation of the driving shaft, and a supporting bearing is installed on the other side to support the driving shaft.

[0011] Furthermore, a plurality of breaking and stirring rollers are provided along the extension direction of the mixing tube to improve the mixing degree of the solid waste in the mixing tube.

[0012] Furthermore, in the same horizontal direction, two breaking and stirring devices are arranged in the mixing tube to improve the mixing degree of the solid waste in the mixing tube.

[0013] Furthermore, a motor for driving the scattering and stirring roller to rotate is installed on the outer wall of the mixing tube, thereby providing power support for the scattering and stirring roller.

[0014] Furthermore, a breaking and stirring roller is provided in the feed pipe to improve the mixing degree of the solid waste in the feed pipe.

[0015] Furthermore, the interior of the mixing tube is coated with a Teflon coating, and the mixing tube sprayed with the Teflon coating has the advantages of being corrosion-resistant and wear-resistant, not easy to deform, lubricating and non-sticky, high temperature resistant, and having a low friction coefficient.

[0033] like Figures 1 to 6 The present invention shows a dual-cracking-tube cracking furnace material distribution and delivery device, which is installed at the front end of the cracking furnace 1. Two cracking tubes 2 are installed in the cracking furnace 1. A vertically arranged feeding pipe 3 is arranged above each cracking tube 2. The material distribution and delivery device comprises a material feeding storage box 4, a mixing pipe and a material distribution mechanism 7. A material storage space 41 for accommodating solid waste is arranged in the material feeding storage box 4, and a material feeding port is opened above the material storage space 41. The mixing pipe is vertically arranged below the material feeding storage box 4, and the mixing pipe is connected to the material storage space 41. A horizontally arranged scattering and stirring roller 6 is installed in the mixing pipe. The material distribution mechanism 7 includes a material distribution pipe 71, a first screw conveying device 72 and a second screw conveying device 73 arranged on the inner side of the material distribution pipe 71, a feed port 74 connected to the mixing pipe is opened in the middle of the material distribution pipe 71, and discharge ports 75 connected to the feed pipe 3 are opened at both ends of the material distribution pipe 71, the first screw conveying device 72 and the second screw conveying device 73 are both in a horizontal state and coaxially arranged, and the spiral blades 76 of the first screw conveying device 72 and the second screw conveying device 73 have opposite rotation directions to realize the distribution of solid waste and improve the cracking efficiency and cracking quality of the cracking furnace 1.

[0034] In one embodiment, first, the solid waste to be cracked is poured into the feeding storage box 4 from the feeding port. The solid waste in the storage space 41 flows into the mixing tube under the action of its own gravity, and the scattering and stirring roller 6 in the mixing tube scatters the solid waste in the mixing tube to improve the mixing uniformity of the solid waste. The solid waste flowing through the mixing tube enters the distribution tube 71 from the feeding port of the distribution tube 71. Since the distribution port is located in the middle position of the distribution tube 71, the first spiral conveying device 72 and the second spiral conveying device 73 in the distribution tube 71 have opposite rotation directions, so half of the solid waste flows along the first spiral conveying device 72 to the left discharge port 75 of the distribution tube 71, and falls into the cracking tube 2 on the left through the feeding tube 3; the other half of the solid waste flows along the second spiral conveying device 73 to the right discharge port 75 of the distribution tube 71, and falls into the cracking tube 2 on the right through the right feeding tube 3, so as to realize the distribution of solid waste. Finally, the cracking furnace 1 performs cracking operation on the solid waste in the cracking tube 2 .

[0035] Preferably, a collecting barrel 8 is provided at the connection between the mixing pipe and the feeding storage box 4, and the width of the collecting barrel 8 gradually decreases to be consistent with the width of the mixing pipe in the vertical downward direction, so as to facilitate the solid waste in the storage space 41 to flow to the mixing pipe.

[0036] In one embodiment, the volume of the feeding storage box 4 is relatively large and has a certain storage function. In order to allow as much solid waste as possible in the feeding storage box 4 to flow to the mixing pipe, a collecting barrel 8 is arranged between the feeding storage box 4 and the mixing pipe to achieve the collection of the materials in the feeding storage box 4.

[0037] Preferably, two feeding regulators 9 are installed in the collecting barrel 8, and the feeding regulator 9 includes a baffle plate 91, a driving bolt 92 and a threaded sleeve 93. The baffle plate 91 is hinged to the connection between the collecting barrel 8 and the feeding storage box 4, the driving bolt 92 is hinged to the side of the baffle plate 91 away from the feeding storage box 4, the threaded sleeve 93 is fixed to the outer wall of the collecting barrel 8, and the collecting barrel 8 is provided with a through hole aligned with the internal space of the threaded sleeve 93. The driving bolt 92 passes through the through hole and the threaded sleeve 93 and is threadedly connected to the threaded sleeve 93, so as to adjust the flow rate of the solid waste in the storage space 41 to the mixing pipe.

[0038] In one embodiment, when adjusting the outflow speed of the solid waste in the feeding storage box 4, the driving bolt 92 can be screwed, and the driving bolt 92 moves linearly relative to the threaded sleeve 93 to lift the inclined baffle plate 91, and the baffle plate 91 gradually rotates to a horizontal state, thereby blocking the solid waste flowing out of the feeding storage box 4, so as to reduce the flow speed of the solid waste flowing into the mixing pipe. On the contrary, rotating the driving bolt 92 in the opposite direction can increase the flow speed of the solid waste flowing into the mixing pipe.

[0039] Preferably, a Teflon coating is sprayed on the upper side of the baffle plate 91. The baffle plate 91 sprayed with the Teflon coating has the advantages of being corrosion-resistant and wear-resistant, not easy to deform, lubricating and non-sticky, high temperature resistant, and having a low friction coefficient.

[0040] Preferably, the first screw conveying device 72 and the second screw conveying device 73 share a driving shaft 77, and a driving motor 78 is installed on one side of the driving shaft 77 to provide power support for the rotation of the driving shaft 77. A supporting bearing 79 is installed on the other side to support the driving shaft 77.

[0041] Preferably, a plurality of breaking and stirring rollers 6 are provided along the extending direction of the mixing tube to improve the mixing degree of the solid waste in the mixing tube.

[0042] Preferably, in the same horizontal direction, two breaking and stirring devices are provided in the mixing tube to improve the mixing degree of the solid waste in the mixing tube.

[0043] Preferably, a motor 61 for driving the scattering and stirring roller 6 to rotate is installed on the outer wall of the mixing tube, thereby providing power support for the scattering and stirring roller 6 .

[0044] In one embodiment, the output shaft of the motor 61 passes through the mixing tube and is connected to the breaking and stirring roller 6. It should be noted that although the output shaft of the motor 61 passes through the mixing tube and there is a certain rotation gap between the output shaft and the mixing tube wall, this does not affect the sealing of the mixing tube, that is, solid waste basically does not flow out of the gap between the mixing tube wall and the output shaft of the motor 61.

[0045] Preferably, a breaking and stirring roller 6 is provided in the feed pipe 3 to improve the mixing degree of the solid waste in the feed pipe 3 .

[0046] Preferably, the interior of the mixing tube is coated with a Teflon coating. The mixing tube sprayed with the Teflon coating has the advantages of being corrosion-resistant and wear-resistant, not easy to deform, lubricating and non-sticky, high temperature resistant, and having a low friction coefficient.

[0047] When the above-mentioned double cracking tube cracking furnace material distribution and feeding device is used, two cracking tubes 2 are installed in the cracking furnace 1 to increase the cracking efficiency of the cracking furnace 1. The two cracking tubes 2 use the same feeding storage box 4 to ensure that the content of solid waste in the two cracking tubes 2 is basically the same, thereby ensuring the cracking quality of the cracking furnace 1.

[0048] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
