Description

Technical Field

[0001] The utility model relates to the technical field of bridge deck paving, in particular to an epoxy asphalt mixture binder feeding device. Background Art

[0002] Epoxy asphalt has been widely used in the paving of steel bridge decks. Its excellent performance and convenient construction methods have been recognized by the majority of builders. Epoxy binder is an important component of epoxy asphalt concrete steel bridge deck paving. The performance of the binder is the determining factor affecting the mixing quality of epoxy asphalt concrete and is the key to the success of the epoxy asphalt concrete paving scheme on steel bridge decks.

[0003] The production process of epoxy asphalt mixture is similar to that of traditional concrete, that is, stone and powder are mixed according to the grading, and then the mixed epoxy binder and asphalt are added and mixed. However, the two components of epoxy must be mixed evenly before adding to the mixture. Epoxy materials are generally two components, namely the main agent and the curing agent. The main agent is epoxy, which has a high viscosity at room temperature. For ease of use, it is generally heated to reduce its viscosity and then pumped out for use. The curing agent has a low viscosity and generally does not need to be heated in advance. It can be directly pumped out for use. In order to ensure the stable performance of the binder after mixing, the two components of the binder need to be mixed evenly according to the proportion.

[0004] However, currently commonly used concrete production equipment does not have a dedicated epoxy binder feeding device and can only use manual feeding and mixing, which will lead to inconvenient feeding and inaccurate metering during production, affecting the efficiency of the entire production and the quality of the mixture. Utility Model Content

[0005] Based on this, it is necessary to provide an epoxy asphalt mixture binder feeding device to address the problem that manual feeding and stirring of epoxy binder leads to inconvenient feeding and inaccurate metering during production.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1 In one embodiment, the epoxy asphalt mixture binder feeding device includes a main agent storage tank 10, a curing agent storage tank 20, a weighing and stirring tank 30, a main agent feeding system 40 and a curing agent feeding system 50.

[0030] The main agent storage tank 10 is used to store the main agent material. In one embodiment, since the main agent has a high viscosity at room temperature, it is generally necessary to heat it to reduce its viscosity before use for ease of use. Therefore, the main agent tank interlayer is provided on the side wall of the main agent storage tank 10, and heat transfer oil is provided in the main agent tank interlayer. The heat transfer oil is used to heat the main agent material in the main agent storage tank 10. The heating of the heat transfer oil can be achieved by setting an electric heating wire in the main agent tank interlayer.

[0031] The curing agent storage tank 20 is used to store the curing agent material. Since the curing agent has low viscosity and does not need to be heated, the curing agent storage tank 20 is a single-layer tank.

[0032] In one embodiment, in order to meet the production material needs while reducing the volume of the storage tank 31, a feeding tray 60 is provided on the top of the main agent storage tank 10 and the curing agent storage tank 20. The feeding tray 60 is provided with a feeding hole 62 with a diameter smaller than that of the binder packaging tube. The feeding tray 60 can rotate. When feeding, the binder packaging tube is turned upside down on the feeding hole 62. After the packaging barrel rotates on the tank for one circle, the adhesive in the barrel has been basically poured out.

[0033] The weighing and stirring tank 30 is used to be arranged above the production stirring pot, and is used to accurately weigh the main agent material and the curing agent material, and to mix the main agent and the curing agent uniformly. In one embodiment, the weighing and stirring tank 30 includes a tank body 31, a weighing module 32 and a stirring device 33.

[0034] Specifically, the tank body 31 is provided with a support block 34 for bearing on the production stirring pot, so as to install the weighing stirring tank 30 above the production stirring pot. The weighing module 32 is arranged below the support block 34. When the support block 34 is carried on the production stirring pot, the weighing module 32 is located between the support block 34 and the production stirring pot.

[0035] The weighing module 32 can accurately measure the epoxy binder added to the tank each time. Only one set of weighing modules 32 is used to weigh the mixing tank 30. When two groups of components are added, they are added one after another and weighed cumulatively. In this embodiment, four support blocks 34 are provided, and the four support blocks 34 are evenly spaced along the circumferential direction of the tank body 31, and a weighing module 32 is installed under each support block 34.

[0036] The stirring device 33 is mounted on the bracket of the production stirring pot, and the stirring device 33 extends into the tank body 31. The stirring device 33 is not directly fixed to the weighing stirring tank 30, so as to avoid the influence of the stirring device 33 on the weighing. In one embodiment, the stirring device 33 can be a stirring device driven by a motor. The bottom wall of the tank body 31 is also provided with a pneumatic valve 35, and the discharge port of the pneumatic valve 35 is connected to the production stirring pot through a pipeline. The pipeline should have a certain distance from the production stirring pot to avoid affecting the weighing.

[0037] Please also read Figure 2 , the main agent feeding system 40 connects the main agent storage tank 10 and the weighing and stirring tank 30 to transport the main agent material in the main agent storage tank 10 to the weighing and stirring tank 30. In one embodiment, the main agent feeding system 40 includes a main agent feeding pipeline 42 and a main agent pump 44, the main agent feeding pipeline 42 connects the main agent storage tank 10 and the weighing and stirring tank 30, and the main agent pump 44 is installed on the main agent feeding pipeline 42. Among them, the main agent pump 44 can pump the main agent material in the main agent storage tank 10 into the main agent feeding pipeline 42, and then transport it to the weighing and stirring tank 30, so as to realize automatic feeding and weighing of the main agent material.

[0038] On the basis of the above embodiment, further, because the production equipment is intermittent production, the feeding of the epoxy binder is also intermittent. Specifically, the main agent feeding system 40 also includes a main agent circulation pipeline 46, which is used to circulate the main agent material pumped out by the main agent pump 44 back to the main agent storage tank 10 when no feeding is needed.

[0039] Among them, when the main agent feeding system 40 is in the feeding state, the main agent material is pumped into the weighing and stirring tank 30; when the main agent feeding system 40 is in the circulation state, the main agent pump 44 does not stop working, and circulates the main agent material back to the main agent storage tank 10 through the main agent circulation pipeline 46, avoiding damage caused by frequent startup of the main agent pump 44.

[0040] In one embodiment, the main agent circulation pipeline 46 and the main agent feeding pipeline 42 are connected through the first three-way valve 48. Specifically, two opposite interfaces of the first three-way valve 48 are respectively connected to two sections of the main agent feeding pipeline 42, and one end of the main agent circulation pipeline 46 is connected to the third interface of the first three-way valve 48, and the other end of the main agent circulation pipeline 46 is connected to the main agent storage tank 10, and the main agent pump 44 is provided on the main agent feeding pipeline 42 between the first three-way valve 48 and the main agent storage tank 10, so that the main agent pump 44 can pump the main agent material into the subsequent main agent feeding pipeline 42, or pump it into the main agent circulation pipeline 46.

[0041] In one embodiment, in order to clean the residual adhesive in the pipeline, the main agent pump 44 has a reverse mode. After production, the residual adhesive in the main agent feeding pipeline 42 can be pumped back to the main agent storage tank 10 for storage, which saves adhesive and prevents pipeline and pump blockage.

[0042] In one embodiment, the epoxy asphalt mixture binder feeding device also includes a heat transfer oil circulation system 70, and the main agent pump 44 is a jacket pump. The heat transfer oil circulation system 70 is used to suck out the heat transfer oil in the main agent tank interlayer, heat the main agent pump 44, and then circulate it back into the main agent tank interlayer to prevent the main agent pump 44 from being cooled due to excessive viscosity when it is used for the second time, causing the pump starting resistance to increase.

[0043] On the basis of the above embodiment, the heat transfer oil circulation system 70 further includes a heat transfer oil circulation pipeline 72 and a heat transfer oil pump 74. After the heat transfer oil circulation pipeline 72 is connected to the main agent tank interlayer, it is connected to the interlayer of the main agent pump 44. Then, the heat transfer oil circulation pipeline 72 is connected from the interlayer of the main agent pump 44 to the interlayer of the main agent tank. The heat transfer oil pump 74 is installed on the heat transfer oil circulation pipeline 72. The heat transfer oil pump 74 is used to extract the heat transfer oil in the interlayer of the main agent tank, and circulate it back to the interlayer of the main agent tank after passing through the interlayer of the main agent pump 44.

[0044] The curing agent feeding system 50 connects the curing agent storage tank 20 and the weighing and stirring tank 30 to transport the curing agent material in the curing agent storage tank 20 to the weighing and stirring tank 30. The main agent material and the curing agent material are added to the weighing and stirring tank 30 in sequence, and the two components are added in sequence and weighed in a cumulative weighing manner.

[0045] In one embodiment, the curing agent feeding system 50 includes a curing agent feeding pipeline 52 and a curing agent pump 54. The curing agent feeding pipeline 52 connects the curing agent storage tank 20 and the weighing and stirring tank 30. The curing agent pump 54 is installed on the curing agent feeding pipeline 52. The curing agent pump 54 can suck the curing agent material stored in the curing agent storage tank 20 into the curing agent feeding pipeline 52, and then send it into the weighing and stirring tank 30.

[0046] On the basis of the above embodiment, further, because the production equipment is intermittent production, the feeding of the epoxy binder is also intermittent. Specifically, the curing agent feeding system 50 also includes a curing agent circulation pipeline 56, which is used to circulate the curing agent material pumped out by the curing agent pump 54 back into the curing agent storage tank 20 when no feeding is needed.

[0047] Among them, when the curing agent feeding system 50 is in the feeding state, the curing agent material is pumped into the weighing and stirring tank 30; when the curing agent feeding system 50 is in the circulation state, the curing agent pump 54 does not stop working, and circulates the curing agent material back to the curing agent storage tank 20 through the curing agent circulation pipeline 56, avoiding damage caused by frequent startup of the curing agent pump 54.

[0048] In one embodiment, the curing agent circulation pipeline 56 and the curing agent feeding pipeline 52 are connected through the second three-way valve 58. Specifically, two opposite interfaces of the second three-way valve 58 are respectively connected to two sections of the curing agent feeding pipeline 52, and one end of the curing agent circulation pipeline 56 is connected to the third interface of the second three-way valve 58, and the other end of the curing agent circulation pipeline 56 is connected to the curing agent storage tank 20, and the curing agent pump 54 is provided on the curing agent feeding pipeline 52 between the second three-way valve 58 and the curing agent storage tank 20, so that the curing agent pump 54 can pump the curing agent material into the subsequent curing agent feeding pipeline 52, or pump it into the curing agent circulation pipeline 56.

[0049] In one embodiment, in order to clean the residual adhesive in the pipeline, the curing agent pump 54 has a reverse mode. After production, the residual adhesive in the curing agent feeding pipeline 52 can be pumped back to the curing agent storage tank 20 for storage, which saves adhesive and prevents pipeline and pump blockage.

[0050] The working principle of the above-mentioned epoxy asphalt mixture binder feeding device is as follows:

[0051] The support block 34 of the weighing and stirring tank 30 is carried on the production stirring pot, and the pipeline of the discharge port of the pneumatic valve 35 is connected to the production stirring pot, thereby completing the installation of the weighing and stirring tank 30 .

[0052] The heat transfer oil in the interlayer of the main agent tank heats the main agent material in the main agent storage tank 10, and the main agent material and the curing agent material are successively added to the weighing and stirring tank 30, and weighed in a cumulative weighing manner. Specifically, when the main agent feeding system 40 is in the feeding state, the curing agent feeding system 50 is in the circulation state. When the curing agent feeding system 50 is in the feeding state, the main agent feeding system 40 is in the circulation state.

[0053] During the process of adding the main agent and curing agent, the feeding tray 60 is used to replenish the material in the storage tank. When feeding, the binder packaging tube is turned upside down on the feeding hole 62 of the feeding tray 60, and the material falls into the storage tank through the feeding hole 62. The binder packaging tube rotates one circle, and the adhesive in the barrel can be basically poured out.

[0054] When the weight ratio of the main agent and the curing agent meets the requirements, the main agent feeding system 40 and the curing agent feeding system 50 are switched to the circulation state, and then switched to the feeding pipeline at the next mixing time, which can avoid frequent starting. The stirring device 33 mixes the materials. After the main agent and the curing agent are mixed evenly, the pneumatic valve 35 is opened, and the mixed epoxy binder is added to the production stirring pot, and stirred together with the stone powder. After mixing evenly, the mixture is discharged.

[0055] After the construction is completed, the main agent pump 44 and the curing agent pump 54 are placed in reverse mode to pump the remaining binder in the feeding pipeline back to the storage tank for storage to prevent the pipeline and pump from being blocked. The thermal oil pump 74 is turned on, and the thermal oil also heats the main agent pump 44 to prevent the main agent temperature from dropping and causing the pump to stick.

[0056] The above-mentioned epoxy asphalt mixture binder feeding device can realize automatic feeding, weighing and stirring of the main agent and curing agent. The feeding is convenient and the metering is accurate during production, which ensures the overall production efficiency and the quality of the mixture. The use of heat transfer oil to circulate in the interlayer of the storage tank has a better heating effect. The main agent pump 44 and the curing agent pump 54 can be reversed and pumped back, making it easier to clean the pipeline. It can be intelligently connected with the mixture production device, and a higher degree of intelligent production can be achieved, reducing manual labor.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
