Description

Technical Field

[0001] This utility model relates to the field of road marking technology, and in particular to a road marking paint dispensing device. Background Technology

[0002] Road marking paint is a high-viscosity fluid paint. It is mixed in the factory and then packaged into 10- to 25-liter containers before being transported to the road construction site for marking. Existing large storage tanks are mainly designed for powders, small particles, or low-viscosity fluids, so their structure is fundamentally different from that of tanks used for high-viscosity materials. For example, storage tanks for granules and powders do not require extrusion devices, which means that cleaning only requires opening the top cover and rinsing with a high-pressure water gun. However, if the road marking paint is not rinsed promptly, it will solidify and stick to the tank walls if exposed to air for a long time, making cleaning more difficult. Therefore, it is particularly important to reduce the cleaning area and scope of the inner wall of each storage tank after use.

[0003] The existing technical solutions have the following drawbacks: it is not easy to clean the inside of large storage tanks. Utility Model Content

[0004] The purpose of this invention is to provide a road marking paint dispensing device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A road marking paint dispensing device includes a storage tank. A pressing device is installed at the top of the storage tank to expel material from the bottom of the tank. A metering dispensing device is detachably installed at the bottom of the storage tank. The pressing device includes a ring, a partition, a sealing ring, and a positioning ring. A groove is provided in the middle of the outer ring of the ring, and the sealing ring is fitted into the groove on the ring. The partition is fixedly installed inside the ring and cooperates with the ring to divide the interior of the storage tank into upper and lower sections. Two interconnected chambers are provided. The positioning ring is fixedly installed on the top of the partition plate. The positioning ring is used to cooperate with the circular ring to prevent the circular ring from tilting during vertical movement. The top of the storage tank is completely open. A sealing plate is detachably installed on the top of the storage tank. The sealing plate is used to completely seal the top of the storage tank. An air inlet that runs vertically through the center of the sealing plate is provided. A feed inlet is provided at the bottom end of the storage tank. A discharge outlet is provided at the center of the bottom of the storage tank. The quantitative dispensing device is connected to the discharge outlet.

[0007] By adopting the above technical solution, the material is filled into the storage tank through the cooperation of the feed inlet and the tank truck. Then, high-pressure gas is sent into the space at the top of the storage tank through the air inlet. The high-pressure gas forces the ring to descend. The ring, the sealing ring and the partition work together to squeeze the material inside the storage tank from the bottom outlet into the quantitative dispensing device, thus realizing quantitative dispensing. In fact, the ring, the sealing ring and the partition form a piston structure.

[0008] In a further embodiment, the storage tank consists of a cylindrical shell portion at the top and a frustum-shaped shell portion at the bottom, the inlet is located on the frustum-shaped shell portion, and the bottom of the partition and the ring is provided with a frustum-shaped surface that cooperates with the interior of the storage tank.

[0009] By adopting the above technical solution, when it is necessary to clean the inside of the storage tank, the inlet is opened to reduce the air pressure in the top chamber of the storage tank, causing the ring and partition to move up a certain distance. At the same time, the quantitative dispensing device is removed, and then a high-pressure water gun is inserted into the storage tank from the inside of the inlet. The bottom of the ring and partition, as well as the bottom side wall and the bottom of the storage tank, are then rinsed to achieve rapid cleaning of the inside of the storage tank. The reason why it is faster than the traditional method is that the ring has already scraped the material on the inner wall of the storage tank clean during the downward movement. Only the space between the bottom of the ring and partition and the inner wall of the storage tank still has material residue.

[0010] In a further embodiment, a plug is detachably provided inside the feed inlet.

[0011] By adopting the above technical solution, a round tube is installed at the bottom of the storage tank. The inner diameter of the round tube is the same as the inner diameter of the feed inlet. The round tube is completely located on the outside of the storage tank. The outer wall of the round tube is threaded. Then, the sealing effect is achieved by screwing a plug.

[0012] In a further embodiment, the quantitative dispensing device consists of a valve and a weighing platform, the valve being screwed to the bottom of the discharge port, and the weighing platform being spaced below the valve.

[0013] By adopting the above technical solution, the weighing platform is used to record the weight of the empty barrel, and then records the total weight of the barrel and the material in real time after the filling begins. When the weight is close to 80%, the valve begins to decrease. When the total weight is close to 95% of the target weight, the valve decreases to 10%. This setting ensures that the material in each barrel meets the standard.

[0014] In a further embodiment, a ranging sensor is provided at the top center of the partition, and a corresponding identification area is provided at the bottom center of the sealing plate.

[0015] The above technical solution is used to detect the position of the ring and the partition inside the storage tank.

[0016] In a further embodiment, both the bottom of the ring and the bottom of the partition are provided with a flexible rubber layer.

[0017] By adopting the above technical solution, the material inside the storage tank is squeezed more tightly, avoiding hard contact.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. During use, the material is filled into the storage tank through the inlet in conjunction with the tank truck. Then, high-pressure gas is sent into the space at the top of the storage tank through the air inlet. The high-pressure gas forces the ring to descend. The ring, sealing ring and partition work together to squeeze the material inside the storage tank from the bottom outlet into the quantitative dispensing device, thus achieving quantitative dispensing. In fact, the ring, sealing ring and partition form a piston structure. Attached Figure Description

The top of the storage tank 1 is completely open, and a sealing plate 4 is detachably installed on the top of the storage tank 1. The sealing plate 4 is used to completely seal the top of the storage tank 1. The sealing plate 4 has a through-hole air inlet at its center. The storage tank 1 has a feed inlet at its bottom and a discharge outlet at its bottom center. The quantitative dispensing device 3 is connected to the discharge outlet. The storage tank 1 consists of a cylindrical shell at the top and a frustum-shaped shell at the bottom. The feed inlet is located on the frustum-shaped shell. The bottom of the partition plate 22 and the ring 21 are provided with frustum-shaped surfaces that cooperate with the interior of the storage tank 1. A plug is detachably provided inside the feed inlet. The quantitative dispensing device 3 consists of a valve and a weighing platform.

[0027] The specific implementation process is as follows: During use, the material is filled into the storage tank through the inlet in conjunction with the tank truck. Then, high-pressure gas is sent into the space at the top of the storage tank through the air inlet. The high-pressure gas forces the ring to descend. The ring, sealing ring and partition work together to squeeze the material inside the storage tank from the bottom outlet into the quantitative dispensing device, thus achieving quantitative dispensing. In fact, the ring, sealing ring and partition form a piston structure.

[0028] It should be noted that, in order not to waste the effective storage space inside the storage bin, the larger the taper angle of the bottom surface of the storage bin, the better.
