Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.
As shown in Figure 1, based on the concrete continuous stirring pumping control system of 3D printing described in the present embodiment, including point
Siccative elevator 2, mortar mixer 3 and mortar pump 5, the water inlet pipe 6 not connecting with control cabinet, the water inlet pipe 6 pass through electromagnetism
Valve is connect with control cabinet, and the solenoid valve is specially flow of digit display control valve.
The entrance of the siccative elevator 2 connects feed bin 1, the entrance of siccative elevator 2 outlet and mortar mixer 3
Connection, the outlet of the mortar mixer 3 are connect with mortar pump 5, and the mortar pump 5 has the function of that timing pumps.It is described into
The top of the entrance of mortar mixer 3 is arranged in the water outlet of water pipe 6, further includes 3D printer 7, the outlet of the mortar pump 5
It is connect with the entrance of the 3D printer 7, the 3D printer 7 is also connect with control cabinet.
It further include weighing system, the weighing system is arranged between siccative elevator 2 and mortar mixer 3, specifically
The weighing system is connect with the entrance of the outlet of siccative elevator 2, the outlet of water inlet pipe 6 and mortar mixer 3 respectively, the title
Material system is also connect with control cabinet.
The weighing system include siccative claim 41 and water claim 42, the outlet of the siccative elevator 3 claims 41 to be connected to siccative,
The outlet of the water inlet pipe 6 claims 42 to be connected to water.It can be understood that the present invention can be direct after the completion of being weighed by weighing system
It is dosed to vertical mortar mixer, has the function of that quantitative timing weighs uninterruptedly upper siccative.
Movable baffle is arranged in the outlet of the mortar mixer 3, has the function of that timing agitation and discharging, mortar completion are stirred
Directly it can enter mortar pump by bottom blowing after mixing.
As shown in Fig. 2, the control cabinet of the embodiment of the present invention passes through control siccative elevator, running water pipe solenoid valve, siccative
Title, water claim, vertical mixer and mortar pump control the function into siccative, water inlet, stirring, discharging, pumping in turn, realize that timing is fixed
Amount stirs and pumps 3D printing material.
The specific rate-determining steps of the embodiment of the present invention are as follows:
The productivity range of 3D printer rationally is deduced, and assumes that 3D printer productivity is 25L/10min;
According to the productivity of 3D printer, the usage amount of convert dry mash, water mixes and stirs the 3D printing concrete material needs of 25L
Dry mash 50Kg, water 7Kg (guarantee that the guarantor of 3D printing mortar collapses the time for 10min, i.e. the jumping table fluidity of 3D printing mortar exists
Loss in 15min is less than 10mm);
Dry mash is put into feed bin, is transported in blender by dry mash elevator, is arranged by control cabinet, every 10min claims
Measure 50Kg dry mash;Every 10min is controlled into 7Kg water by flowmeter simultaneously.Dry mash and water the mix 3min in blender, are stirred
The storage bin of 3D printer is pumped to after the completion of mixing by mortar pump, wherein the total linear spacing of each cyclic process is 10min;It can be with
Accurately complete the mortar of every 10min printing 25L;Continuous printing 2h, printing height is more than 2m, and bottom is without obvious deformation, printing
Face is smooth.
It is arranged after the completion of printing by control cabinet, stops siccative charging, continue to keep water inlet, completes vertical mortar stirring
The cleaning of machine, pump and 3D printer storage bin, printing port.This set system realizes the full automation of 3D printing substantially, liberation
Productivity, reduces production cost, improves production efficiency.
Continuous mixing and pumping system are not used, only with the individual identical 3D printer of artificial feed mode,
Need at least two workers to be uninterruptedly fed, and worker's discharging, feed including shipping time just more than 10min, and due to people
For the uncontrollability of time, so it is up to 25L/20min using the productivity of the 3D printer of the method for artificial loading, with
Guarantor is collapsed for time 20min.By taking every 20min prints 25L as an example, when printing to 1h, due to bottom deformation, entire 3D printing
Structures collapse, and printing surface out-of-flatness.So this continuous stirring system not only increases production efficiency, identical 3D is beaten
Print machine productivity has been increased to 25L/10min from 25L/20min, and has saved the artificial of feeding, also reduces printing and collapses
A possibility that failure.
Compared to the concrete continuous stirring of 3D printing cleaned automatically and pumping production line, by the way of being manually fed
Individual identical 3D printer needed at the end of printing worker hold water pipe cleaning, increase cleaning difficulty, also increase
Cost of labor.
