Description
Technical Field
The invention relates to the technical field of material conveying, in particular to a double-ion-layer lubrication structure, equipment and a lubrication method based on pipeline transportation.
Background
The material conveying efficiency can be improved by lubricating in the material conveying process, and the abrasion of a conveying pipeline is reduced. In the prior art, the lubrication method and the structure used in the material conveying process are various.
Taking concrete delivery as an example, the prior art concrete requires that the inner wall of the delivery tube be lubricated with a suitable amount of cement paste or cement mortar of the same composition as the concrete prior to pumping. And in the process of pumping concrete, a pumping agent is usually required to be added into the concrete, wherein the pumping agent refers to an additive capable of improving the pumping performance of the concrete mixture. The pumping performance is that the concrete mixture has good performance of smoothly passing through a conveying pipeline, no blockage, no segregation and good viscoplasticity.
In other words, there are various pumping devices for delivering concrete or the like, such as pump truck, vehicle-mounted pump, drag pump, stirring and distributing pump truck, wet spraying machine, etc., and the pumping device in the prior art generally has the following structure: the device comprises a hopper for holding materials, a pumping mechanism for pumping the hopper, a distributing mechanism connected with the pumping mechanism and a stirring mechanism connected with the distributing mechanism, wherein the distributing mechanism mainly adopts an S valve or a skirt valve as a distributing element for distributing.
When the S valve is adopted, the two single-action plunger cylinders push the S valve to swing, so that the sucking and discharging of the pumping cylinder are realized. The S valve plays a supporting role through the large end supporting ring and the small end supporting ring. Through adjusting the nut, can make S pipe axial displacement to make the cutting ring that overlaps on the S valve compress tightly the eye board, guarantee the leakproofness in the pumping process.
When the skirt valve is adopted, the skirt valve is pushed to swing by the two single-acting plunger cylinders, so that the suction and discharge of the pumping cylinders are realized. Because the skirt valve structure is different from the S valve structure, the aggregate flow resistance is smaller than that of the S valve structure when the skirt valve structure is used for pumping, but the material sucking property is poorer than that of the S valve structure.
The mode of carrying out material conveying lubrication by adding the pumping agent or improving the pumping device has higher cost.
It can be seen that the prior art is still in need of improvement and development.
