Embodiment 1

[0039] refer to figure 1 , The pumping addition metering system includes a feed pipe 100 , a pump body 200 , a regulating valve 320 and a discharge pipe 300 connected in sequence along the flow direction of raw materials. Connect the feed pipe 100 with the container containing the raw materials, and the end of the discharge pipe 300 away from the pump body 200 is connected with the mixer, open the regulating valve 320, and start the pump body 200, so that the pump body 200 pumps the liquid raw materials into the mixing machine inside the plane.

[0040] In order to make the pumping and adding metering system stop running, the regulating valve 320 can be closed in time, so that the material in the discharge pipe 300 is not easy to be poured back, so the regulating valve 320 includes a valve body 322 and a controller 321, and the controller 321 and the valve body 322 to control the opening and closing of the valve body 322, the controller 321 is electrically connected to the pu...

Embodiment 2

[0048] When the operation of the pumping and adding metering system is finished and the staff cleans the pumping and adding metering system with cleaning agent, it is easy to appear that the side wall of the discharge pipe 300 away from the pump body 200 is not easy to be cleaned, resulting in the occurrence of the inner wall of the discharge pipe 300. The situation of partly bonding materials, so for this kind of situation, the difference between this embodiment and embodiment one is: refer to image 3 and Figure 4 , The discharge pipe 300 includes a connecting sub-pipe 400 , a connecting sub-pipe 500 and a sliding sub-pipe 600 , one end of the connecting sub-pipe 400 communicates with the flow meter 310 , and the other end communicates with the connecting sub-pipe 500 . The sliding sub-tube 600 is located inside the connecting sub-tube 500, and there are multiple support rods 610 connected to the sliding sub-tube 600. The tubes 600 are distributed uniformly in the axial di...

Abstract

The invention relates to the field of asphalt concrete production, in particular to a liquid pumping, adding and metering system for pavement mixture raw materials, which comprises a feed pipe, a pump body and a discharge pipe which are communicated in sequence, the pump body is a pump body with an external bearing, and the discharge pipe is communicated with a flowmeter. Compared with a conventional pump body, the pump body with the external bearing has great advantages, the situation that the pump body is adhered or damaged due to the fact that the viscosity of raw materials is too large in the pavement material transferring process is reduced, and therefore the defects existing when the conventional pump is used are reduced; in addition, the adjusting valve, the pump body and the flow meter are effectively fused, and the liquid raw material pumping, adding and metering system which is simple, convenient and convenient to move is formed.

Description

technical field [0001] The present application relates to the field of equipment for pavement material production, in particular to a liquid pumping and adding metering system for pavement mixture raw materials. Background technique [0002] During the production process of pavement materials, staff are required to pour various raw materials of pavement materials into the mixer through pouring equipment for mixing. [0003] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: when the viscosity of the raw material is higher than that of asphalt, when the existing pouring equipment pours the raw materials into the mixer, the pouring equipment is prone to malfunction Condition. Contents of the invention [0004] In order to prevent the pouring equipment from malfunctioning when pouring raw materials into the mixer, the application provides a liquid pumping and adding metering system for road mixture raw materials. ...
