Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixing stations, in particular to a powder material metering and conveying system for a foamed asphalt cold regeneration mixing station. Background Art

[0002] Asphalt is a viscous, black, and highly viscous liquid or semi-solid petroleum with a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt: among them, coal tar asphalt is a by-product of coking, petroleum asphalt is the residue after crude oil distillation, and natural asphalt is stored underground, some of which form mineral layers or accumulate on the surface of the earth's crust.

[0003] The Chinese patent publication number CN117166317A proposes "a foamed asphalt cold recycling mixing station powder metering and conveying system". This technical solution points out the problem that "the existing technology requires manual weighing of asphalt according to a certain ratio during mixing, which is time-consuming and labor-intensive, and the equipment weighing is not convenient for adjusting the conveying speed according to the weight of the asphalt powder."

[0004] The above scheme has the following defects: the above device for weighing powder is a horizontal weighing structure. Since it uses the lever principle for weighing, it will occupy a large space during use. Therefore, a powder metering and conveying system for a foamed asphalt cold regeneration mixing station is proposed to solve the above problem. Utility Model Content

[0007] The weighing and metering mechanism includes a discharge pipe fixedly installed at the bottom of the asphalt mixing station, a supporting base frame fixedly installed at the bottom of the asphalt mixing station, four limit vertical rods fixedly installed at the bottom of the asphalt mixing station, a No. 1 ring plate slidably installed on the outside of the four limit vertical rods, a storage barrel fixedly installed at the bottom of the No. 1 ring plate, a No. 2 ring plate fixedly installed at the bottom of the storage barrel, a conveying channel fixedly installed at the bottom of the No. 2 ring plate, a connecting pipe fixedly installed at the bottom of the inner cavity of the storage barrel and penetrating into the conveying channel, a metering scale fixedly installed at the bottom of the inner cavity of the supporting base frame, and a buffer mechanism located at the bottom of the conveying channel.

[0012] Furthermore, the discharge pipe is located at the center of the asphalt mixing station, and the four limit vertical rods are all located inside the supporting frame.

[0013] The beneficial effect of adopting the above further solution is that the asphalt in the asphalt mixing plant is discharged through the discharge pipe, and the bottom of the asphalt mixing plant is supported by the supporting frame.

[0014] Furthermore, the four limit vertical rods are all fixedly installed on the bottom of the inner cavity of the supporting frame, and the four limit vertical rods are respectively located at the front, back, left and right ends of the No. 1 ring plate.

[0015] The beneficial effect of adopting the above further solution is that the first ring plate is restricted to rise and fall outside the discharge pipe by four limiting vertical rods.

[0016] Furthermore, the No. 1 ring plate is sleeved on the outside of the discharge pipe, the outside of the storage barrel is funnel-shaped, and the storage barrel is located on the inner side of four limiting vertical rods.

[0017] The beneficial effect of adopting the above further solution is that the asphalt discharged from the discharge pipe is contained in the storage barrel.

[0018] Furthermore, the second ring plate slides up and down outside the four limit vertical rods, the left side of the conveying channel is an open structure, and the conveying channel is connected with the storage barrel through a connecting pipe.

[0019] The beneficial effect of adopting the above further scheme is that the contact area between the bottom of the storage barrel and the outside world is increased by the second ring plate, which also serves the purpose of restricting the bottom of the storage barrel to prevent the bottom of the storage barrel from shaking. The asphalt falling into the storage barrel can be guided into the interior of the conveying channel through the connecting pipe.

[0020] Furthermore, the two springs are fixedly mounted on the bottom of the conveying channel, and the two springs are respectively sleeved on the outside of the two dampers.

[0021] The beneficial effect of adopting the above further scheme is that the conveying channel and the storage barrel are supported at the bottom of the weighing scale by two dampers and two springs. At this time, the weighing scale can weigh the asphalt falling into the storage barrel. At this time, the two dampers and the springs can cooperate to alleviate the impact of the asphalt falling into the storage barrel.

[0022] Furthermore, the output end of the DC motor faces leftward, the discharging auger is rotatably installed inside the conveying channel, and the discharging auger is rotatably installed on the right side of the L side frame.

[0023] The beneficial effect of adopting the above further solution is that the discharge auger is supported by the L side frame to rotate inside the conveying channel, and the DC motor drives the discharge auger to rotate to guide the asphalt inside the conveying channel to the outside.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] The powder metering and conveying system of the foamed asphalt cold regeneration mixing station directly guides the asphalt inside the asphalt mixing station into the storage barrel through the discharge pipe. At this time, the weight of the asphalt inside the storage barrel can be measured by the metering scale, and then the asphalt inside the storage barrel falls into the inside of the conveying channel. The DC motor drives the discharge auger to rotate and guide the asphalt inside the conveying channel to the outside. In this regard, the weighing and metering mechanism and the spiral conveying structure of the device are both located at the bottom of the asphalt mixing station, thereby achieving the effect of occupying a small space.
