Description

Technical Field

[0003] The viscosity of emulsified asphalt liquid is relatively high. If the emulsified asphalt liquid is filled into a spreader by conventional filling methods, the filling efficiency of the emulsified asphalt liquid is limited due to the slow flow rate of the emulsified asphalt liquid.

[0007] Specifically, the rear side pumping and pushing liquid port is connected with a temporary storage pipeline, a pumping and pushing hydraulic cylinder is arranged at the rear side of the temporary storage pipeline, and a piston of the pumping and pushing hydraulic cylinder is slidably matched with the temporary storage pipeline.

The longitudinal guide rod on one side is slidably connected to a front stroke limit sensor, and the longitudinal guide rod on the other side is slidably connected to a rear stroke limit sensor. Both the front stroke limit sensor and the rear stroke limit sensor are threadedly connected to the longitudinal screw rod.

[0009] Specifically, openings are provided on both lateral sides of the three-way valve seat, flanges are fixedly connected to the openings, a ball bearing is provided at the middle opening of the flange, and an end cover is fixedly connected to the outer end surface of the flange.

[0012] Specifically, the upper liquid inlet of the three-way valve seat is connected to the lower end of the Y-shaped tube through a clamp.

[0013] Specifically, the front end of the conduit is connected to the horizontal pipe of the T-shaped irrigation head through a clamp.

[0014] Specifically, the front end of the temporary storage pipeline is connected to the rear side liquid extraction and pushing port provided on the three-way valve seat through a clamp.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] After the asphalt is heated and melted, it is injected into the emulsified asphalt tank, and then emulsifier and water are added to the emulsified asphalt tank to mix and obtain emulsified asphalt liquid. Emulsified asphalt liquid is a mixture of water and emulsion, and can still maintain liquid at room temperature. It can be spread after adding water at the construction site. Before adding water, the emulsified asphalt liquid has a high viscosity. If the emulsified asphalt is poured into the asphalt spreader (not shown) by conventional filling method, the filling process efficiency is low due to the high viscosity and low flow rate of the emulsified asphalt liquid.

[0017] In order to efficiently and quickly inject the emulsified asphalt liquid into the emulsified asphalt spreader (not shown in the figure), the present invention is specially provided with a three-way valve seat, a temporary storage pipeline and a pumping and pushing hydraulic cylinder.

[0018] A cylindrical cavity is provided inside the three-way valve seat, and a valve core is rotatably provided in the cylindrical cavity. The inner wall of the cylindrical cavity and the outer wall of the valve core form a liquid seal. Figure 4 In the state shown, the core body liquid outlet on the lower side is closed by the bottom wall of the three-way valve seat, and the upper liquid inlet is connected to the temporary storage pipeline. The piston rod of the hydraulic cylinder is retracted to draw the emulsified asphalt liquid into the temporary storage pipeline for temporary storage. The hydraulic cylinder can generate sufficient suction force to quickly draw the viscous emulsified asphalt liquid into the temporary storage pipeline for temporary storage. Then, the swing cylinder drives the valve core to rotate until the core body liquid outlet is facing downward, so that the core body liquid outlet is closed by the bottom wall of the three-way valve seat, so that the temporary storage pipeline is connected to the conduit. Then, the piston rod of the hydraulic cylinder is extended outward to push the emulsified asphalt liquid in the temporary storage pipeline into the T-type filling head. The hydraulic cylinder can generate sufficient thrust to quickly push the viscous emulsified asphalt liquid into the T-type filling head.

[0019] The opening cylinder adjusts the liquid discharge rate of the injection pipe by controlling the position of the opening control rod.

[0020] Both sides of the push-pull hydraulic cylinder are fixed with longitudinal guide rods and longitudinal screw rods. The longitudinal guide rod on one side is slidably connected to a front stroke limit sensor, and the longitudinal guide rod on the other side is slidably connected to a rear stroke limit sensor. The front stroke limit sensor and the rear stroke limit sensor can sense the piston position of the push-pull hydraulic cylinder. By rotating the longitudinal screw rod to adjust the longitudinal position of the front stroke limit sensor and the rear stroke limit sensor, the piston stroke of the push hydraulic cylinder can be set, thereby setting the amount of emulsified asphalt liquid extracted by the push hydraulic cylinder at a time. If the emulsified asphalt liquid with a higher viscosity is extracted, the single extraction amount is reduced, and if the emulsified asphalt liquid with a lower viscosity is extracted, the single extraction amount is increased.

[0045] Specifically, the front end of the conduit 231 is connected to the horizontal pipe of the T-shaped irrigation head 5 through a clamp.

[0046] Specifically, the front end of the temporary storage pipe 61 is connected to the rear side liquid extraction and pushing port 22 provided on the three-way valve seat 2 through a clamp.

[0047] The working principle of the present invention is as follows:

[0048] After the asphalt is heated and melted, it is injected into the emulsified asphalt tank 11, and then an emulsifier and water are added to the emulsified asphalt tank 11 to mix and obtain emulsified asphalt liquid. The emulsified asphalt liquid is a mixture of water and emulsion, and can still maintain a liquid state at room temperature. It can be spread after adding water at the construction site. Before adding water, the emulsified asphalt liquid has a high viscosity. If the emulsified asphalt is poured into the asphalt spreader (not shown) by a conventional filling method, the filling process is inefficient due to the high viscosity and low flow rate of the emulsified asphalt liquid.

[0049] In order to efficiently and quickly inject the emulsified asphalt liquid into the emulsified asphalt spreader (not shown), the present invention is specially provided with a three-way valve seat 2, a temporary storage pipeline 61 and a pumping and pushing hydraulic cylinder 62.

[0050] See Figure 4 , a cylindrical cavity is provided inside the three-way valve seat 2, a valve core 3 is rotatably provided in the cylindrical cavity, and the inner wall of the cylindrical cavity forms a liquid seal with the outer wall of the valve core 3. When the valve core 3 is in a position such as Figure 4In the state shown, the core body liquid outlet 33 on the lower side is closed by the bottom wall of the three-way valve seat 2, and the upper side liquid inlet 21 is connected to the temporary storage pipe 61. The piston rod of the hydraulic cylinder 62 is retracted to draw the emulsified asphalt liquid into the temporary storage pipe 61 for temporary storage. The hydraulic cylinder 62 can generate sufficient suction force to quickly draw the viscous emulsified asphalt liquid into the temporary storage pipe 61 for temporary storage. Then, the swing cylinder 4 drives the valve core 3 to rotate until the core body liquid outlet 32 ​​faces downward, so that the core body liquid outlet 32 ​​is closed by the bottom wall of the three-way valve seat 2, so that the temporary storage pipe 61 is connected to the conduit 231. Then, the piston rod of the hydraulic cylinder 62 is extended outward to push the emulsified asphalt liquid in the temporary storage pipe 61 into the T-shaped filling head 5. The hydraulic cylinder 62 can generate sufficient thrust to quickly push the viscous emulsified asphalt liquid into the T-shaped filling head 5.

[0051] The opening cylinder 53 adjusts the liquid discharge rate of the liquid injection pipe 51 by controlling the position of the opening control rod 52 .

[0052] Both sides of the hydraulic cylinder 62 are fixedly connected with longitudinal guide rods and longitudinal screw rods 71. The longitudinal guide rod on one side is slidably connected with a front stroke limit sensor 72, and the longitudinal guide rod on the other side is slidably connected with a rear stroke limit sensor 73. The front stroke limit sensor 72 and the rear stroke limit sensor 73 can sense the piston position of the hydraulic cylinder 62. By rotating the longitudinal screw rod 71 to adjust the longitudinal positions of the front stroke limit sensor 72 and the rear stroke limit sensor 73, the piston stroke of the hydraulic cylinder 62 can be set, thereby setting the amount of emulsified asphalt liquid extracted by the hydraulic cylinder 62 at a time. If the emulsified asphalt liquid with a higher viscosity is extracted, the single extraction amount is reduced, and if the emulsified asphalt liquid with a lower viscosity is extracted, the single extraction amount is increased.
