Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of negative carbon plate, and particularly relates to a waste gas capturing and negative carbon plate forming equipment. BACKGROUND

[0002] The negative carbon plate is a plate or brick with a stone-like texture, which is formed by uniformly mixing industrial solid wastes such as steel slag (50-70%), carbide slag (5-15%), fly ash (5-15%), etc. as the main component, and a small amount of cement (10-20%) and fiber reinforced materials, and then pressing the mixture into a plate blank. The plate blank is dried at 30-60℃, and the water content is controlled at 10-25%. Then the plate blank is carbonized by introducing industrial tail gas containing CO2 into the carbonization equipment at a temperature of 20-40℃ for 6-24 hours. The plate blank absorbs CO2 to increase the structural strength. The active components such as calcium and magnesium in the solid waste react with CO2 to form carbonate, achieving carbon sequestration. The plate blank without carbonization has a bending strength of about 4.5-7MPa, while the carbonized plate blank has a bending strength of about 17-20MPa, which is 3-4 times higher than that of the plate blank without carbonization. The water absorption of the carbonized plate blank is reduced from 20% to less than 9%, and the waterproof performance is improved by more than 50%. Each ton of plate blank can sequester about 200kg of CO2, and the amount of captured and fixed CO2 is greater than the amount of CO2 generated by the total energy consumption of the production process, achieving net negative carbon.

[0006] Preferably, in the waste gas capturing and negative carbon plate forming equipment of the present application, a reinforcing member is arranged at the four corners of the pressure maintaining intermediate mold, and the pressure maintaining mold outer frame is provided with a matching surface A for sliding cooperation with the reinforcing member.

[0007] As the waste gas trapping type negative carbon plate material forming equipment of the application, the reinforcing part is provided with a missing corner, the height of the missing corner is greater than the height of the negative carbon plate blank, the bottom position of the pressure maintaining intermediate die is lower than the bottom position of the reinforcing part, and the adjacent pressure maintaining intermediate die can maintain the pressure of the negative carbon plate blank.

[0008] As the waste gas trapping type negative carbon plate material forming equipment of the application, the pressure maintaining die outer frame can have a relative linear displacement relative to the negative carbon plate blank during pressure maintaining.

[0009] As the waste gas trapping type negative carbon plate material forming equipment of the application, the preforming device comprises a preforming support fixed on a high platform, a hydraulic cylinder A fixedly connected to the inner top end of the preforming support, a forming pressure die B fixedly connected to the end of the telescopic main shaft of the hydraulic cylinder A, a hydraulic cylinder B fixedly connected to the inner bottom end of the preforming support, an extrusion bottom support fixedly connected to the end of the telescopic main shaft of the hydraulic cylinder B, a forming pressure die A fixedly connected to the top end of the extrusion bottom support, and a preforming die outer frame fixedly connected to one end of the preforming support and matched with the forming pressure die and the forming pressure die B.

[0010] As the waste gas trapping type negative carbon plate material forming equipment of the application, the pressure maintaining device further comprises a pressure maintaining device frame, a hydraulic cylinder C fixedly connected to one end of the pressure maintaining device frame through a hydraulic cylinder connecting piece A, a pressure maintaining pressure die A fixedly connected to the end of the telescopic main shaft of the hydraulic cylinder C, a hydraulic cylinder D fixedly connected to the other end of the pressure maintaining device frame through a hydraulic cylinder connecting piece A, and a pressure maintaining pressure die B fixedly connected to the end of the telescopic main shaft of the hydraulic cylinder D.

[0011] As the waste gas trapping type negative carbon plate material forming equipment of the application, when the negative carbon plate blank or the pressure maintaining intermediate die is placed in the pressure maintaining die outer frame, the top surface of the pressure maintaining pressure die B or the top surface of the placed negative carbon plate blank or the top surface of the pressure maintaining intermediate die is lower than the top surface of the pressure maintaining die outer frame by a distance of half the pressure maintaining intermediate die.

[0012] As the waste gas trapping type negative carbon plate material forming equipment of the application, the inner side of the pressure maintaining device frame is fixedly connected with a sliding fixing piece, the outer side of the pressure maintaining die outer frame is fixedly connected with a sliding matching piece, and the sliding matching piece is slidingly connected with the sliding fixing piece.

[0013] As the waste gas trapping type negative carbon plate material forming equipment of the application, the inner side of the pressure maintaining device frame is fixedly connected with a hydraulic cylinder connecting piece B, the inner side of the hydraulic cylinder connecting piece B is fixedly connected with a hydraulic cylinder E, and the end of the telescopic main shaft of the hydraulic cylinder E is fixedly connected with the bottom end of the sliding matching piece. The bottom end of the pressure maintaining device frame is rotationally connected with the low platform, and a hydraulic cylinder F is rotationally connected between the outer side of one end of the pressure maintaining device frame and the low platform.

[0014] Compared with the prior art, the beneficial effects of the present invention are: by first pressing the negative carbon slab blank under high pressure of 7-30 MPa using a pre-forming device, and then placing several pressed negative carbon slab blanks into a pressure-holding forming device for joint pressure holding within the range of 5-20 MPa, the problem of continuous operation caused by the need for pressure holding when directly using a blank pressing forming device to press the negative carbon slab blank can be avoided. The pressure-holding forming device is actually a device for mechanically extruding multiple negative carbon slab blanks together. To facilitate the placement of the negative carbon slab blanks into the pressure-holding forming device, in When placing the negative carbon slab blanks into the pressure-holding forming device, the device is set vertically. When enough negative carbon slab blanks are loaded into the device and pressure needs to be maintained, the device is set horizontally. Since the pressure-holding forming device actually extrudes multiple negative carbon slab blanks by pressing them against each other using pressure-holding molds A and B, if the device is set vertically, the negative carbon slab blanks at the bottom will experience greater pressure due to their own weight, while the negative carbon slab blanks at the top will experience less pressure. This problem can be solved by placing the device horizontally. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1-12 As shown: A waste gas capture and negative carbon plate forming equipment, which presses the negative carbon plate blank 5 into shape through a pre-forming device 1. The pre-forming device 1 can be a plate pressing and forming device in the prior art. Several negative carbon plate blanks 5 are placed in a vertically arranged pressure holding and forming device 2. When pressure is held by the pressure holding and forming device 2, the pressure holding and forming device 2 is set horizontally. The pressure holding forming device 2 includes a pressure holding mold outer frame 201 and pressure holding molds A206 and B207 for pressing several negative carbon slabs 5 against each other. The pressure holding forming device 2 is installed on the low platform 4, and the preforming device 1 is installed on the high platform 3.

[0018] The negative carbon plate is a plate (plate or brick) with a near stone texture, which is formed by uniformly mixing steel slag (50-70%), carbide slag (5-15%), fly ash (5-15%) and a small amount of cement (10-20%) and fiber reinforced materials, and then drying the formed plate at 30-60°C to control the moisture content to 10-25% and then carbonizing. During carbonization, the plate is sent to a carbonization equipment and industrial tail gas containing CO2 is introduced, and the plate is carbonized at a temperature of 20-40°C for 6-24 hours to increase the structural strength of the plate after absorbing CO2. The active components such as calcium and magnesium in the solid waste react with CO2 to form carbonate, realizing carbon sequestration. The plate without carbonization has a bending strength of about 4.5-7MPa, while the carbonized plate has a bending strength of about 17-20MPa, which is 3-4 times higher than the plate without carbonization. The water absorption of the carbonized plate is reduced from 20% to less than 9%, and the waterproof performance is improved by more than 50%. Each ton of plate can sequester about 200kg of CO2, and the amount of captured and fixed CO2 is greater than the amount of CO2 generated by the total energy consumption of the production process, realizing net negative carbon. However, during the plate forming process, it needs to be mechanically extruded in a mold at a pressure of 5-20MPa for 2-3 hours. The traditional production method of continuous extrusion for 2-3 hours will seriously delay the production progress. In order to improve the efficiency of the negative carbon plate 5 forming process, the negative carbon plate 5 is first formed by a preforming device 1 at a high pressure of 7-30MPa, and then the formed negative carbon plate 5 is placed in a pressure maintaining forming device 2 for pressure maintaining. The pressure maintaining pressure is in the range of 5-20MPa. This can avoid the problem of continuous work caused by the need for pressure maintaining during the plate forming process. The pressure maintaining forming device 2 is actually a device for mechanically extruding multiple negative carbon plates 5. In order to facilitate the placement of the negative carbon plate 5 in the pressure maintaining forming device 2, the pressure maintaining forming device 2 is vertically arranged when the negative carbon plate 5 is placed in the pressure maintaining forming device 2. When the pressure maintaining forming device 2 is filled with enough negative carbon plates 5 for pressure maintaining, the pressure maintaining forming device 2 is horizontally arranged. Since the pressure maintaining forming device 2 actually extrudes multiple negative carbon plates 5 by pressure maintaining dies A 206 and pressure maintaining dies B 207, if the pressure maintaining forming device 2 is vertically arranged, the extrusion force on the bottom negative carbon plate 5 will be larger due to the self-gravity of the stacked negative carbon plates 5, while the extrusion force on the upper negative carbon plate 5 will be smaller. The horizontal arrangement can solve this problem.

[0019] In an optional embodiment, a pressure maintaining intermediate die 202 is arranged between the negative carbon plates 5 in the pressure maintaining die outer frame 201.

[0020] In this embodiment, in order to improve the forming quality and shape of the negative carbon slab 5, a pressure maintaining intermediate die 202 is arranged between adjacent negative carbon slabs 5 to avoid the problem of uneven negative carbon slabs 5 during extrusion.

[0021] In an optional embodiment, a reinforcing member 203 is arranged at the four corners of the pressure maintaining intermediate die 202, and the pressure maintaining die outer frame 201 is provided with a matching surface A 205 for sliding cooperation of the reinforcing member 203.

[0022] In this embodiment, in order to avoid or reduce the problem of non-parallelism of several negative carbon slabs 5 during simultaneous extrusion, that is, the non-parallelism between the two planes of a single negative carbon slab 5, the problem is better solved by reducing or preventing the pressure maintaining intermediate die 202 from deviating, and a reinforcing member 203 is added at the four corners of the pressure maintaining intermediate die 202, the height of the reinforcing member 203 is greater than that of the pressure maintaining intermediate die 202, and the structural stability between the reinforcing member 203 and the pressure maintaining die outer frame 201 is increased, preventing or reducing the deviation of the pressure maintaining intermediate die 202, and thus ensuring the parallelism of the two planes of the negative carbon slab 5.

[0023] In an optional embodiment, the reinforcing member 203 is provided with a missing corner 204, the height of the missing corner 204 is greater than the height of the negative carbon slab 5, the bottom position of the pressure maintaining intermediate die 202 is lower than the bottom position of the reinforcing member 203, and adjacent pressure maintaining intermediate dies 202 can maintain pressure on the negative carbon slab 5.

[0024] In this embodiment, the reinforcing member 203 is provided with a missing corner 204, and the arrangement of the missing corner 204 cooperates with the pressure maintaining intermediate die 202 to accommodate the complete negative carbon slab 5 without affecting the structure of the negative carbon slab 5. The height of the missing corner 204 is greater than the height of the negative carbon slab 5, so that during extrusion, the negative carbon slab 5 located at the missing corner 204 will not lack blocking. Because the reinforcing member 203 is located at the matching surface A 205, if the height of the negative carbon slab 5 is greater than the height of the missing corner 204, then during extrusion, the negative carbon slab 5 located at the missing corner 204 will be extruded into the matching surface A 205, while the negative carbon slab 5 at other side positions except the missing corner 204 can be blocked by the matching surface B 2051. The bottom position of the pressure maintaining intermediate die 202 is lower than the bottom position of the reinforcing member 203. Since the negative carbon slab 5 is extruded, its thickness will be further reduced by a small amount. Therefore, when two pressure maintaining intermediate dies 202 jointly extrude the negative carbon slab 5, the opposite movement of the two pressure maintaining intermediate dies 202 will not be blocked by the reinforcing member 203, which is also a necessary condition to ensure that adjacent pressure maintaining intermediate dies 202 can maintain pressure on the negative carbon slab 5.

[0025] In an optional embodiment, during pressure maintaining, the pressure maintaining die outer frame 201 can relatively linearly displace relative to the negative carbon slab 5.

[0026] In this embodiment, when the several negative carbon plate blanks 5 are extruded by the pressure die A 206 and the pressure die B 207, the negative carbon plate blanks 5 are displaced due to compression, friction between the side surface of the negative carbon plate blank 5 and the matching surface B 2051 is generated, and friction between the pressure intermediate die 202 and the reinforcing part 203 and the pressure die outer frame 201 is also generated. The extrusion force of the several negative carbon plate blanks 5 is gradually transmitted, and as the number of negative carbon plate blanks 5, the pressure intermediate die 202, and the reinforcing part 203 increases, the extrusion force of the negative carbon plate blank 5 located closer to the position of the pressure die A 206 and the pressure die B 207 is greater due to the influence of friction. Taking the negative carbon plate blank 5 close to the pressure die A 206 and the negative carbon plate blank 5 far from the pressure die A 206 as an example, when the pressure α transmitted to the negative carbon plate blank 5 far from the pressure die A 206, the pressure β applied by the pressure die A 206 is definitely greater than the pressure α due to the dispersion of a part of the force by friction during transmission. This will result in uneven force on each negative carbon plate blank 5 due to the gradual dispersion of friction. In order to solve this problem, after the pressure die A 206 and the pressure die B 207 apply the rated pressure, the friction between the negative carbon plate blank 5, the pressure intermediate die 202, the reinforcing part 203, and the pressure die outer frame 201 is eliminated by actively moving the pressure die outer frame 201 multiple times, so that the pressure is more evenly distributed to each negative carbon plate blank 5. After the pressure is evenly distributed, the negative carbon plate blank 5 that was not effectively extruded before may now be effectively extruded, resulting in a thinner thickness. The pressure feedback before may be reduced, so the rated pressure before should be applied again by the pressure die A 206 and the pressure die B 207. Of course, there should be a sufficient time interval between the two pressure applications, and the value of the pressure feedback should be stable.

[0027] In an alternative embodiment, the preforming device 1 comprises a preforming support 101 fixed on the high platform 3, the inner top end of the preforming support 101 is fixedly connected with a hydraulic cylinder A 102, the telescopic main shaft of the hydraulic cylinder A 102 is fixedly connected with a forming pressure die B 106 at the end, the inner bottom end of the preforming support 101 is fixedly connected with a hydraulic cylinder B 103, the telescopic main shaft of the hydraulic cylinder B 103 is fixedly connected with an extrusion bottom support 104 at the end, the top end of the extrusion bottom support 104 is fixedly connected with a forming pressure die A 105, and one end of the preforming support 101 is fixedly connected with a preforming die outer frame 107 matched with the forming pressure die and the forming pressure die B 106 through a connecting support 108.

[0028] In this embodiment, the powder for making the negative carbon slab 5 is placed in the preforming mold outer frame 107, at this time the top surface of the extrusion base 104 should be in contact with the bottom surface of the preforming mold outer frame 107, then the forming mold B 106 is driven downward by the hydraulic cylinder A 102, after extrusion forming, the forming mold B 106 is moved upward by the hydraulic cylinder A 102 to return to the original position, the hydraulic cylinder B 103 drives the extrusion base 104 to drive the forming mold A 105 to move downward, so that the forming mold A 105 lifts the negative carbon slab 5 to move downward and completely separate from the preforming mold outer frame 107, then the negative carbon slab 5 is taken out, the surfaces of the preforming mold outer frame 107, the forming mold A 105 and the forming mold B 106 should be coated with release agent.

[0030] In this embodiment, the hydraulic cylinder C 208 drives the pressure holding mold A 206 to move linearly, and the hydraulic cylinder D 209 drives the pressure holding mold B 207 to move linearly, so as to directly or indirectly extrude the pressure holding intermediate mold 202 or the negative carbon slab 5.

[0031] In an optional embodiment, when the negative carbon slab 5 or the pressure holding intermediate mold 202 is placed in the pressure holding mold outer frame 201, the top surface of the pressure holding mold B 207 or the top surface of the placed negative carbon slab 5 or the top surface of the pressure holding intermediate mold 202 is lower than the top surface of the pressure holding mold outer frame 201 by half the distance of the pressure holding intermediate mold 202.

[0032] In this embodiment, in order to make it more convenient to put the negative carbon slab 5 or the pressure maintaining intermediate mold 202 into the pressure maintaining mold frame 201, for example, when the pressure maintaining intermediate mold 202 is put in for the first time, the top surface of the pressure maintaining intermediate mold 202 is lowered than the top surface of the pressure maintaining mold frame 201 by half the distance of the pressure maintaining intermediate mold 202 by the active movement of the hydraulic cylinder D 209, so as to facilitate the placement of the pressure maintaining intermediate mold 202, and then the pressure maintaining intermediate mold 202 put in for the first time becomes the placed pressure maintaining intermediate mold 202, at this time, the hydraulic cylinder D 209 is controlled to shrink again, so that the placed pressure maintaining intermediate mold 202 moves downward until the top surface of the pressure maintaining intermediate mold 202 is lowered than the top surface of the pressure maintaining mold frame 201 by half the distance of the pressure maintaining intermediate mold 202, so as to facilitate the placement of the negative carbon slab 5, although the thickness of the negative carbon slab 5 and the thickness of the pressure maintaining intermediate mold 202 are different, the distance of the hydraulic cylinder D 209 shrinking each time is regular, the control structure can be pre-set the stroke of the hydraulic cylinder D 209 shrinking each time, or the work of the hydraulic cylinder D 209 can be directly controlled manually by remote control or local control.
