Description

Technical Field

[0001] The utility model relates to the technical field of quantitative adding devices, in particular to a low-temperature auxiliary agent quantitative adding machine for producing asphalt waterproofing coiled materials. Background Art

[0002] Ordinary self-adhesive asphalt waterproofing membranes are affected by storage, cold weather and other factors, and their viscosity is reduced, which affects the construction quality. In order to solve the above viscosity problems, low-temperature additives are added to the formula to improve the low-temperature flexibility of the membrane, and low-temperature tackifiers are added. Low-temperature production is adopted in the production process, and high-temperature silicone oil membrane materials are used for the isolation membrane. The development of this technology allows the storage period of the self-adhesive membrane to be extended, and the viscosity will not decrease at low temperatures, which improves the construction quality, increases sales revenue, and generates better economic benefits. The ratio of asphalt and low-temperature additives in the formula is certain. Since the low-temperature additives have a large viscosity, and in order to make the asphalt and low-temperature additives mix more evenly, the low-temperature additives need to be slowly added to the asphalt.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN217490745U discloses a low-temperature additive quantitative adding machine for the production of strong self-adhesive asphalt waterproofing membrane, which is characterized in that it includes a storage tank, a metering tank and an automatic control system, a discharge pipe is connected between the bottom end of the storage tank and the upper end of the metering tank, and a first automatic valve is provided on the discharge pipe; the upper end of the storage tank and the upper end of the metering tank are connected with a ventilation pipe, and a second automatic valve is provided on the ventilation pipe; the upper end of the storage tank is also provided with an air intake pipe, and a third automatic valve is provided on the air intake pipe; the bottom of the metering tank is provided with a flow addition pipe, and a fourth automatic valve is provided on the flow addition pipe; the bottom of the metering tank is connected to a bracket through a weighing device, and at the end of the flow addition of the low-temperature additive in the metering tank of the patent, the compressed air in the metering tank can blow the material adhered to the wall of the metering tank into the asphalt tank, thereby reducing the residual low-temperature additive in the metering tank, making the addition amount more accurate, and the pressure in the storage tank and the metering tank is also released.

[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is that the method of using compressed air to blow the material adhering to the metering tank into the asphalt tank is not ideal, resulting in the material easily remaining on the inner wall of the metering tank, thereby affecting the accuracy of the addition amount.

[0006] To this end, we proposed a low-temperature additive quantitative adding machine for the production of asphalt waterproofing membranes to solve the above-mentioned drawbacks. Utility Model Content

[0026] Please refer to Figure 1-4 A low-temperature additive quantitative adding machine for asphalt waterproofing membrane production includes a metering tank 1 and a fixing component 11. A tank cover 2 is detachably installed on the top of the metering tank 1, and an electric cylinder 3 is fixedly installed on the top surface of the tank cover 2, and the telescopic end of the electric cylinder 3 extends to the inside of the metering tank 1 and a pressure block 12 is detachably installed through the fixing component 11. A feed pipe 4 and an air intake pipe 5 are fixedly installed on the top surface of the tank cover 2, a discharge pipe 6 is fixedly installed on the bottom of the metering tank 1, and a valve is installed on the discharge pipe 6, a bottom plate 7 is arranged below the metering tank 1, and a weighing device 8 is installed on the bottom plate 7, a bracket 9 is welded to the outer wall of the metering tank 1, and the lower end of the bracket 9 is arranged on the surface of the weighing device 8.

[0027] In this embodiment: the fixing assembly 11 is composed of a fixing block 111, a connecting block 112, a positioning hole 113, a positioning rod 114, a clearance hole 115 and a support plate 116. The fixing block 111 is installed on the telescopic end of the electric cylinder 3, and the connecting block 112 is fixedly installed on the top surface of the pressure block 12. The fixing block 111 is matched with the connecting block 112. The surface of the connecting block 112 is provided with a positioning hole 113, and the positioning hole 113 is penetrated by a positioning rod 114. The surface of the fixing block 111 is provided with a clearance hole 115, and one end of the positioning rod 114 extends into the clearance hole 115. The outer wall of the positioning rod 114 is welded with a support plate 116, and the outer side of the positioning rod 114 is provided with a spring 117, and the two ends of the spring 117 are fixedly connected to the support plate 116 and the clearance hole 115.

[0028] Specifically, open the feed pipe 4 to inject the low-temperature additive into the metering tank 1, and introduce compressed air into the metering tank 1 through the air intake pipe 5. After the pressure in the tank reaches the preset value of the control panel 10, the control panel 10 controls the air intake pipe 5 to close and no longer intake air. Then the weighing device 8 sends a weight signal to the control panel 10. When the weight reaches the preset weight, the control panel 10 controls the feed pipe 4 to close and controls the discharge pipe 6 to open. Under the action of air pressure, the low-temperature additive begins to flow into the asphalt tank. The compressed air in the metering tank 1 can blow the material adhered to the wall of the metering tank 1 into the asphalt tank, reducing the residual low-temperature additive in the metering tank 1 and making the addition amount more accurate. At the same time, the piston rod of the electric cylinder 3 is extended and retracted to push the pressure block 12 downward, which can move the metering tank 1. The low-temperature auxiliary agent remaining on the inner wall is cleaned, so that the low-temperature auxiliary agent is not easy to remain and adhere to the inner wall of the metering tank 1, and the cleaning effect is more ideal, making the amount of low-temperature auxiliary agent added more accurate. Secondly, the setting of the fixing component 11 is convenient for replacing the pressure block 12, avoiding the formation of a gap between the pressure block 12 and the inner wall of the metering tank 1 after wear, ensuring the cleaning effect and efficiency of the low-temperature auxiliary agent adhered to the inner wall of the pressure block 12 and the metering tank 1, and the disassembly and assembly is time-saving and labor-saving. The working principle is: push the positioning rod 114 into the clearance hole 115, and make one end of the positioning rod 114 no longer connected to the positioning hole 113 opened on the surface of the connecting block 112. At this time, the pressure block 12 can be pulled up and down and removed. Conversely, the operation is reversed during installation.

[0029] In this embodiment, the pressure block 12 is used in conjunction with the metering tank 1 .

[0030] Specifically, the cleaning effect and efficiency of the materials attached to the inner wall of the metering tank 1 can be guaranteed.

[0031] In this embodiment: a control panel 10 is fixedly mounted on the outer wall of the metering tank 1 , and the control panel 10 is electrically connected to the electric cylinder 3 and the weighing device 8 through a wire.

[0032] Specifically, it is a common control circuit connection structure, which will not be described in detail here.

[0033] In this embodiment: the air inlet pipe 5 is connected to an external air compressor through an air path.

[0034] Specifically, it is ensured that the compressed air can smoothly enter the metering tank 1 .

[0035] In this embodiment: the bottom of the metering tank 1 is funnel-shaped.

[0036] Specifically, it makes the discharge cleaner and more thorough.

[0037] In this embodiment: the controller is an existing structure, and the control circuit can be implemented by simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.

[0038] Working principle: When in use, open the feed pipe 4 to inject the low-temperature additive into the metering tank 1, and introduce compressed air into the metering tank 1 through the air intake pipe 5. After the pressure in the tank reaches the preset value of the control panel 10, the control panel 10 controls the air intake pipe 5 to close and no longer intake air. Then the weighing device 8 sends the weight signal to the control panel 10. When the weight reaches the preset weight, the control panel 10 controls the feed pipe 4 to close and controls the discharge pipe 6 to open. Under the action of air pressure, the low-temperature additive begins to flow into the asphalt tank. The compressed air in the metering tank 1 can blow the material adhering to the wall of the metering tank 1 into the asphalt tank, reducing the residual low-temperature additive in the metering tank 1 and making the addition amount more accurate. At the same time, the piston rod of the electric cylinder 3 is extended and retracted to push the pressure block 12 downward, which can measure the The low-temperature auxiliary agent remaining on the inner wall of the measuring tank 1 is cleaned, so that the low-temperature auxiliary agent is not easy to remain and adhere to the inner wall of the measuring tank 1, and the cleaning effect is more ideal, making the amount of low-temperature auxiliary agent added more accurate. Secondly, the setting of the fixing component 11 is convenient for replacing the pressure block 12, avoiding the formation of a gap between the pressure block 12 and the inner wall of the measuring tank 1 after wear, ensuring the cleaning effect and efficiency of the pressure block 12 and the low-temperature auxiliary agent adhered to the inner wall of the measuring tank 1, and saving time and effort in disassembly and assembly. Its working principle is: push the positioning rod 114 into the clearance hole 115, and make one end of the positioning rod 114 no longer connected to the positioning hole 113 opened on the surface of the connecting block 112. At this time, the pressure block 12 can be pulled up and down and removed. Conversely, the operation is reversed during installation.

[0039] It should be noted that the model specifications of the electric cylinder 3 and the weighing device 8 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
