Description
Technical Field
The invention relates to the technical field of waterproof coiled material production equipment, in particular to a blanking device for coating an asphalt waterproof coiled material.
Background
The asphalt waterproof coiled material is a coiled material made of asphalt material, base material and surface spreading anti-sticking material, also called asphalt felt, and is commonly used for a pasting type waterproof layer. The asphalt waterproof coiled material comprises a filled coiled material and a non-filled coiled material. The roll-shaped material is made by impregnating base materials such as thick paper or glass fiber cloth, asbestos cloth, cotton and linen fabrics and the like with petroleum asphalt and is called as a base coiled material; asbestos, rubber powder, etc. are mixed into asphalt material, and the rolled material is called rolled coiled material, i.e. tubeless coiled material.
The modified asphalt waterproof coiled material is commonly called modified asphalt felt, and is a curlable sheet-like waterproof material which is prepared by taking a glass fiber felt, a polyester felt, a jute cloth, a polyethylene film, a polyester non-woven fabric, a metal foil or two composite materials as a base, taking synthetic high molecular polymer modified asphalt and oxidized asphalt with the mixing amount of not less than 10% as dip-coating materials and taking powder, sheet and granular mineral materials, synthetic high molecular films and metal films as covering materials. Due to inherent disadvantages of low softening point, high penetration and low temperature brittleness of asphalt itself, the application range of the asphalt is limited when the asphalt is used as a waterproof material. After the asphalt is modified by adding the high molecular polymer, the performances are greatly improved, the weather resistance, the temperature sensitivity (high-temperature characteristic and low-temperature flexibility) and the adaptability to substrate cracking are obviously improved, and the waterproof material prepared by using the modified asphalt is realistic and possible from the traditional 'heavy, thick, long and big' era to the 'light, thin, short and small' industrialized era.
The production process of the waterproof roll material is to dip-coat asphalt on base fabric such as glass fiber cloth or non-woven fabric, and then extrude the base fabric dipped with asphalt to tamp the asphalt on the base fabric. Two procedures of pre-dipping and coating are needed during production; the pre-dipping has the function of soaking the pre-dipping asphalt into the tire base fabric, so that the tire base fabric can be completely soaked with the asphalt, and water channeling and layering of a finished product after the finished product is in contact with water are avoided; the function of coating is to make the asphalt waterproof layers on the upper and lower surfaces of the base fabric of the waterproof roll material meet certain thickness requirements, and more importantly, to finally obtain a tight and uniform waterproof roll material. The currently common coating process is as follows: the method only depends on the adhesion effect of the base cloth to the asphalt coating material to enable the asphalt coating material to stay on the upper surface and the lower surface of the base cloth, so that the thickness of the asphalt on the upper surface and the lower surface of the produced asphalt waterproof coiled material is not easy to adjust, and the base cloth has large tension and serious shrinkage in the later process due to the continuous pressure effect of the compression roller on the base cloth. Accordingly, there is a need for improvements in existing coating devices.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art, and provides a blanking device for coating an asphalt waterproof coiled material, which is used for solving the problems that the thickness of an upper surface asphalt layer of the waterproof coiled material using an immersion coating cover is not easy to control, and the problems of large tension and large shrinkage rate of a base fabric of a tire.
The technical scheme adopted by the invention is as follows:
the utility model provides a blanking device for coating of asphalt waterproofing membrane, is including the fortune material pipe that carries the pitch usefulness, the coating pipe that the pitch blanking was used and the fortune oil pipe that carries the conduction oil usefulness, be equipped with the valve of control flow on fortune material pipe and the fortune oil pipe, the double-deck jacket structure of coating pipe for including the coating inner tube that is used for the pitch material to flow and the coating outer tube that is used for the conduction oil to flow, fortune material pipe passes the coating outer tube, fortune material pipe export is linked together with the coating inner tube, coating inner tube blanking mouth and coating outer tube blanking mouth are established to coating socle portion, coating outer tube blanking mouth is located under the coating inner tube blanking mouth.
In the technical scheme, a mode that the pre-soaked base fabric is pressed into an asphalt coating material pool by using a press roller to enable the base fabric to be adhered with the asphalt coating material on two sides and then leave the material pool to coat the asphalt on the surface of the base fabric is abandoned, and a mode that the base fabric passing below is coated by adopting a blanking device for coating asphalt waterproof coiled materials is adopted.
The coating pipe is of a double-layer jacket structure and comprises a coating inner pipe and a coating outer pipe, asphalt from a batching pool is conveyed into the coating inner pipe through the coating outer pipe through a material conveying pipe on one hand, heat conduction oil with proper temperature is conveyed into the coating outer pipe through an oil conveying pipe on the other hand, heat is supplied to the asphalt in the coating inner pipe through flowing heat conduction oil, and proper temperature and good fluidity of the asphalt are maintained. The coating pipe bottom is established the opening for the pitch blanking, and correspondingly, coating inner tube blanking mouth is seted up to coating inner tube bottom, and coating outer tube blanking mouth is seted up to coating outer tube bottom, and coating outer tube blanking mouth locates under the coating inner tube blanking mouth, makes pitch can fall from coating inner tube blanking mouth, passes coating outer tube blanking mouth and then drops on the child base cloth of coating pipe below horizontal transfer, accomplishes pitch coating process. Through the blanking speed of adjustment coating inner tube blanking mouth pitch and the transfer rate of child base cloth, the thickness of steerable child base cloth upper surface pitch layer conveniently makes the waterproofing membrane of different thickness.
According to the technical scheme, the blanking device for coating the asphalt waterproof coiled material is characterized in that the tire base cloth is in a horizontal shape and is stably conveyed below the blanking device at a constant speed, the tire base cloth does not need to be pressed into an asphalt coating material pool in the coating process, and the tire base cloth is not in a continuous pulling state, so that the conditions of large tension and serious contraction in the back-end process cannot occur.
Further, the longitudinal section of the coating outer tube blanking port is an outward-expanding cone. The design of the outward-expanding conical opening is more than that of a common rectangular opening, so that the asphalt coating material has a larger falling space, the asphalt coating material cannot shake in the falling process due to the vibration of a machine and the like, and the asphalt coating material is adhered to the coating outer tube blanking port, and the blockage caused by the accumulation of the asphalt adhesion at the coating outer tube blanking port in long-time production is avoided.
Further preferably, the taper angle is 30 ° to 60 °. The outward-expanded conical angle is too small, so that the asphalt coating material falls off in a non-linear manner due to the vibration of a machine or unstable coating pressure and the like in the blanking process and is adhered to the conical side surface of the blanking port of the coating outer tube; meanwhile, the taper angle of the outward expansion cannot be too large, and as the heat conduction oil flows between the outer coating pipe and the outer wall of the inner coating pipe, the heat supply and heat preservation effects are achieved for the asphalt coating material in the inner coating pipe, and the heat supply and heat preservation effects are used for keeping the fluidity of asphalt, under the condition that the diameters of the inner coating pipe and the outer coating pipe and the opening size of the blanking opening of the inner coating pipe are fixed, if the outward expansion taper angle is too large, the heat supply of the heat conduction oil is possibly lacked around the blanking opening of the inner coating pipe, the viscosity of the asphalt around the blanking opening of the inner coating pipe is increased due to temperature reduction, and even solidification is caused, so that the.
Preferably, the width of the blanking opening of the coating inner tube is 1-3 mm. According to the thickness requirement of the waterproof roll, the width of the blanking port of the coating inner tube can be controlled, so that the thickness of the asphalt coating material falling on the upper surface of the base fabric below is controlled. If the width of the blanking port of the coating inner tube is less than 1mm, the opening is easily blocked due to the characteristic of high viscosity of asphalt; if the width of the blanking port of the coating inner tube is larger than 3mm, the blanking process is unstable due to the too high dropping speed of the asphalt, so that the thickness of the asphalt layer is difficult to control.
Preferably, the length of the blanking port of the outer coating tube is 1-1.5m, the length of the blanking port of the inner coating tube is 0.8-1.2m, the length of the blanking port of the inner coating tube is smaller than the length of the blanking port of the outer coating tube, and the blanking port of the inner coating tube is located in the middle of the blanking port of the outer coating tube. The coating inner tube blanking port is arranged in the middle of the opening range of the coating outer tube blanking port, so that the asphalt blanking is smooth and not blocked, and the pollution and the opening blockage are avoided.

As a preferred scheme, a baffle penetrating through the longitudinal direction of the coating pipe is arranged between the inner coating pipe and the outer coating pipe, the space between the inner coating pipe and the outer coating pipe is divided into two cavities, an oil inlet and an oil outlet of heat conducting oil are arranged on different cavities at the same end of the outer coating pipe, and an oil through hole for the heat conducting oil to pass through is arranged at the end of one end of the baffle, which is far away from the oil inlet and the oil outlet, so that the heat conducting oil flows in a U-shaped path from the two cavities between the inner coating pipe and the outer coating pipe. The heat transfer oil can be supplied to the asphalt coating material in the coating inner pipe by passing in and out at the same end, and meanwhile, the oil conveying pipe is reduced, the installation space is saved, and the structure of the coating system is more compact and reasonable.
Further preferably, the oil conveying pipes are provided with two groups, each group comprises a first oil conveying pipe and a second oil conveying pipe, the coating pipes are provided with two groups, each group comprises a first coating pipe and a second coating pipe, and oil outlets of the oil conveying pipes on the first coating pipes are communicated with oil inlets of the oil conveying pipes on the second coating pipes through the oil conveying pipes. In the production process of the asphalt waterproof coiled material, the waterproof coiled material with the thickness and the surface flatness meeting the standard can not be produced through one-time coating and pressing, generally, at least one-time coating, rough pressing, secondary coating and fine pressing are required, a coating system consisting of a first conveying pipe and a first coating pipe in the technical scheme can be used for one-time coating, a coating system consisting of a second conveying pipe and a second coating pipe can be used for secondary coating, the one-time coating and the secondary coating share a heat conduction oil system, only an oil outlet of an oil conveying pipe on the first coating pipe and an oil inlet of an oil conveying pipe on the second coating pipe are required to be communicated through one section of oil conveying pipe, the use of the oil conveying pipe is further reduced, and the installation space is saved.
Preferably, the diameter of the conveying pipe is the same as the diameter of the coating inner pipe. Because the outlet end of the material conveying pipe is communicated with the coating inner pipe, the flow state of the asphalt coating material is most stable when the diameters of the two circular pipes are the same. If the diameter of the material conveying pipe is smaller than that of the coating inner pipe, a large amount of bubbles are generated when asphalt enters the coating inner pipe; if the diameter of the material conveying pipe is larger than that of the coating inner pipe, the flow of asphalt at the joint of the two circular pipes is blocked to a certain degree, and the production of high-quality asphalt waterproof coiled materials is not facilitated.
Preferably, the oil carrying pipe is a non-linear pipe. The oil conveying pipe can be a nonlinear pipeline, heat conduction oil conveyed in the oil conveying pipe only has a heat supply effect on asphalt coating materials in the coating inner pipe, and the requirement on stability is low in the flowing process of the heat conduction oil, so that the oil conveying pipe can be designed into a pipeline with a bending angle according to the arrangement condition of other surrounding production equipment so as to avoid important parts such as a coating pipe and an extrusion roller, and the installation space of a coating system is saved.
Preferably, the bent part of the material conveying pipe is provided with a fillet, and the size of the fillet is 70-90 degrees. The material conveying pipe is changed into a vertical pipe from a horizontal pipe after being bent, and a fillet of 70-90 degrees is designed at the middle bent part, so that the asphalt coating material can be conveyed more smoothly and stably.
Compared with the prior art, the invention has the beneficial effects that: the blanking device for coating the asphalt waterproof coiled material can control the thickness of the asphalt layer on the upper surface of the base fabric of the tire, so that the waterproof coiled materials with different thicknesses can be conveniently manufactured, and meanwhile, the situations that the base fabric of the tire has large tension and is seriously contracted in the later process can be avoided.

A baffle penetrating through the longitudinal direction of the first coating tube 310 is arranged between the first coating inner tube 311 and the first coating outer tube 312, the space between the first coating inner tube 311 and the first coating outer tube 312 is divided into two cavities, the first oil inlet 501 and the first oil outlet 502 of heat conduction oil are arranged on different cavities at the same end of the first coating outer tube 312, and the end of the baffle far away from the first oil inlet 501 and the first oil outlet 502 is provided with an oil through port through which the heat conduction oil can pass, so that the heat conduction oil flows in a U-shaped path from the two cavities between the first coating inner tube 311 and the first coating outer tube 312. The heat transfer oil can be supplied to the asphalt coating material in the first coating inner tube 311 through the same-end inlet and outlet of the heat transfer oil, and meanwhile, the oil conveying pipe 500 is reduced, the installation space is saved, and the coating system is more compact and reasonable in structure.
In this embodiment, the taper angle of the longitudinal section of the blanking port 3121 of the first coating outer tube is selected to be 30 °. The outward-expanding conical angle is too small, so that the asphalt coating material falls off non-linearly in the blanking process due to machine shaking or unstable coating pressure and the like and is adhered to the conical side surface of the blanking port 3121 of the first coating outer tube; meanwhile, the taper angle of the outward expansion cannot be too large, and since heat conduction oil flows between the outer wall of the first coating outer pipe 312 and the outer wall of the first coating inner pipe 311, the heat conduction oil plays a role in heat supply and heat preservation for the asphalt coating material in the first coating inner pipe 311 and is used for keeping the fluidity of asphalt, under the condition that the diameters of the first coating inner pipe 311 and the first coating outer pipe 312 are fixed and the opening size of the first coating inner pipe blanking port 3111 is fixed, if the taper angle of the outward expansion is too large, heat conduction oil is possibly lacked around the first coating inner pipe blanking port 3111 for heat supply, so that the viscosity of the asphalt around the first coating inner pipe blanking port 3111 is increased due to temperature reduction, and even solidification occurs, and therefore, the problems that blanking is unstable or the outlet is partially blocked by.
The width of the first coating inner tube blanking port 3111 is 1.5 mm. According to the thickness requirement of the waterproof roll, the width of the blanking port 3111 of the first coating inner tube can be controlled so as to control the thickness of the asphalt coating material dropped on the upper surface of the base fabric below. If the width of the first coating inner tube blanking port 3111 is less than 1mm, the opening is easily blocked due to the characteristic of high viscosity of the asphalt itself; if the width of the blanking port 3111 of the first coating inner tube is larger than 3mm, the asphalt layer is liable to fall at an excessively high speed, which makes the blanking process unstable and makes it difficult to control the thickness of the asphalt layer.
The length of the outer tube blanking opening of the first coating tube 310 is 1.5m, the length of the inner tube blanking opening 3111 of the first coating tube is 1.2m, the length of the inner tube blanking opening 3111 of the first coating tube is less than the length of the outer tube blanking opening 3121 of the first coating tube, and the inner tube blanking opening 3111 of the first coating tube is located in the middle of the outer tube blanking opening 3121 of the first coating tube. With first coating inner tube blanking mouth 3111 setting in the middle position of first coating outer tube blanking mouth 3121 opening range, can make the pitch blanking smooth not receive the hindrance, avoid polluting and block up the opening.
The first conveying pipe 610 has the same diameter as the first coating inner pipe 311. Since the outlet end of the first conveying pipe 610 is communicated with the first coating inner pipe 311, the flowing state of the asphalt coating material is most stable when the diameters of the two circular pipes are the same. If the diameter of the first conveying pipe 610 is smaller than that of the first coating inner pipe 311, a large amount of bubbles are generated when the asphalt enters the first coating inner pipe 311; if the diameter of the first conveying pipe 610 is larger than that of the first coating inner pipe 311, the flow of asphalt at the joint of the two circular pipes is blocked to a certain extent, which is not favorable for producing high-quality asphalt waterproof coiled materials.
The oil transfer pipe 500 is a non-linear pipe. The oil conveying pipe 500 can be a nonlinear pipeline, heat conduction oil conveyed in the nonlinear pipeline only has a heat supply effect on asphalt coating materials in the coating inner pipe, and the requirement on stability in the flowing process of the heat conduction oil is low, so that the oil conveying pipe 500 can be designed into a pipeline with a bending angle according to the arrangement condition of other surrounding production equipment so as to avoid important parts such as a coating pipe and an extrusion roller, and the installation space of a coating system is saved. Heat conducting oil flows in from a first oil inlet 501, flows out from a first oil outlet 502, flows in from a second oil inlet 503 through a section of oil conveying pipe 500, and flows out from a second oil outlet 504.
The first material conveying pipe 610 is provided with a round angle at the bending position, and the size of the round angle is 80 degrees. The first material conveying pipe 610 is changed into a vertical pipe from a horizontal pipe after being bent, and a fillet of 70-90 degrees is designed at the middle bent part, so that the conveying of the asphalt coating materials is smoother and more stable.
The second coating pipe 320 has the same structure as the first coating pipe 310, and the second coating pipe 320 has a double-layered jacket structure including a second coating inner pipe 321 for asphalt to flow and a second coating outer pipe 322 for heat transfer oil to flow. The taper angle of the longitudinal section of the second coating outer tube blanking port 3221 is 30 °, the width of the second coating inner tube blanking port 3211 is 2.5mm, the length of the second coating outer tube blanking port 3221 is 1.5m, and the length of the second coating inner tube blanking port 3211 is 1.2 m. The length of the second coating inner tube blanking port 3211 is less than the length of the second coating outer tube blanking port 3221, and the second coating inner tube blanking port 3211 is located in the middle of the second coating outer tube blanking port 3221. The second conveying pipe 620 has the same diameter as the second coating inner pipe 321. The second fortune pipe 620 kink is equipped with the fillet, and the fillet size is 80.
