[0002] Construction waste can be used to make ecological bricks. This process not only realizes the recycling of resources, but also reduces damage and pollution to the environment. Compared with ordinary bricks, ecological bricks have stronger stability, compression resistance, flexural resistance and freeze-thaw resistance, and can be widely used in urban roads, parking lots, squares, sidewalks and other places. A Chinese patent discloses a construction waste brick-making equipment, application number: 202121379929.1. The equipment opens the mouth of the storage cavity on the lower mold base, saving the time wasted in taking materials, thereby improving work efficiency.

[0022] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use;

[0023] 1. A dynamic shaping structure is provided. Through the coordination of the partition, piston rod and piston plate, driving rod, gear head, runner, shaft rod, bevel gear and gear disc, a double pressure amplification mechanism can be constructed. A raw material stacking conveying passage can be constructed between the barrel, the material box and the transmission box. With the diversion function of the discharge valve, conveying pipe, diverter seat, telescopic pipe, connecting pipe, check valve, trifurcated pipe and exhaust port, a complete transmission passage can be constructed. On the one hand, the driving air pressure of the air pump can be fully utilized. While improving the sufficiency of the air pressure kinetic energy, the load pressure of the air pump can be effectively reduced, the kinetic energy transmission efficiency can be equivalently improved, and the kinetic energy loss in the production process can be reduced. While making the air pump work continuously and stably, the endurance effect and service life of the air pump are improved, and the energy saving effect of the equipment is greatly improved. The kinetic energy is transmitted in the form of gas-liquid mixed drive, which greatly reduces the wear during the transmission process.

[0024] On the other hand, it can effectively ensure the sufficiency and effectiveness of the compacting pressure of the raw material slurry, and can quickly provide the raw material slurry with stable pressure support during the compression and shaping process of the raw material slurry. While ensuring the compression molding efficiency, it can make full use of the elasticity of the gas-liquid transmission to avoid the rigidity and sluggishness of hard extrusion. While making the force of the raw material slurry more balanced and stable, it can effectively avoid the dead corner of compression, so that the raw material slurry can be more fully and efficiently injected into the mold cavity surrounded by the outer mold shell and the inner mold base, making the raw material slurry more complete after compression molding, while improving the molding effect, greatly reducing the residual The product output rate can fully guarantee the output qualification rate of ecological bricks, thereby reducing the demand for secondary processing and effectively improving the processing efficiency. With the mixing function of the stirring head, on the one hand, the raw material slurry inside the barrel can be stirred to promote the mixing of the raw material slurry, and on the other hand, the raw material slurry can be prevented from coagulating. Combined with the pressure-feeding shaping of the raw material slurry, the slurry injected into the mold cavity before and after can be uniform, ensuring the output consistency of the same batch of ecological bricks, thereby making the output specifications of ecological bricks more standardized, and improving the convenience, flexibility and safety of subsequent use of the produced ecological bricks.

[0025] 2. An elastic quality control mechanism is provided. Through the coordination of the bypass seat, the intermediate tube, the side wall tube, the stopper, and the flow cavity, a pressure limiting structure can be constructed. With the air pressure balance and adjustment function of the external cavity, the constant pressure hole, the elbow, the air nozzle and the pressure gauge, the compaction pressure in the shaping process of the eco-brick can be preliminarily limited. The output quality of the eco-brick can be limited and controlled from the molding pressure level, the internal stress of the eco-brick after molding can be accurately controlled, and the molding strength of the eco-brick can be dynamically controlled. While ensuring the output quality and improving the performance consistency of the same batch of products, the specifications of eco-bricks that can be produced by the equipment can be enriched, which can more flexibly meet the market demand for eco-bricks of different specifications, enhance the core competitiveness of the equipment, and make the equipment applicable to a wider range of eco-brick processing and production. With the equivalent detection function of switches, sliding rods and limit contacts, the shaping nodes of eco-bricks can be accurately controlled, greatly improving the flexibility and convenience of the production process;

[0026] By cooperating with the load-bearing rod, the pressure-bearing plate and the accommodating cavity, a gravity control structure can be constructed. With the adjustment and marking functions of the pressure gauge, air valve, guide ear, guide rail and scale, the initial state of the equipment can be corrected and adjusted. On the one hand, the output quality of the eco-bricks can be limited and controlled from the output weight of the eco-bricks. With the limiting effect of the forming pressure, the output quality of the eco-bricks can be linked and limited from multiple dimensions. While improving the flexibility and diversity of quality control work, the quality control of eco-bricks produced in the same batch can be made more accurate and effective. On the other hand, it can compensate for the mechanical wear during the long-term use of the device, which improves the output accuracy of the eco-bricks and extends the effective service life of the mold in disguise.

[0027] To sum up, the eco-brick production equipment can greatly reduce the load pressure of the driving equipment while ensuring the sufficiency and stability of the molding pressure, can ensure the uniformity and stability of the molding pressure during the molding process, can avoid molding dead corners, and can synchronously control the output quality of eco-bricks from multiple dimensions, which can effectively improve the output quality of eco-bricks. The overall operation is more energy-saving and environmentally friendly, and is suitable for better promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Working principle and use process of the present invention: In actual use of the eco-brick production equipment, the support 100 is firstly placed stably on the ground of the working area. When assembly line production is required, an external conveying device can be laid at the bottom of the outer mold shell 101, so that the conveying direction of the external conveying device is flush with the direction of the opening axis at the bottom of the outer mold shell 101. The internal mold base 102 is intermittently conveyed by the external conveying device, and the conveying frequency is set according to the actual preparation requirements. The process can also be manually controlled to control the replacement and transfer frequency of the internal mold base 102.

[0054] Before using this equipment to prepare eco-bricks, it is also necessary to set the relevant output parameters of eco-bricks according to actual production needs. First, use the external inflation equipment to inject air into the flow chamber 315 through the air nozzle 320 and the bend pipe 319, forcing the stopper 312 to abut against the top of the flow chamber 315 under the action of air pressure, cutting off the flow between the side wall tube 311 and the stopper 312, and limiting the air pressure at the bottom of the stopper 312 according to the reading of the pressure gauge 321. In the preparation process of eco-bricks, the pressure at the bottom of the stopper 312 is the compaction pressure in the shaping process of eco-bricks. By changing this pressure, the molding density of eco-bricks can be limited according to actual production needs to produce eco-bricks with different performance strengths.

[0055] Then, the inner mold base 102 is sent into the outer mold shell 101, so that the outer mold shell 101 and the inner mold base 102 are stably fitted, and then the external inflation equipment is used to inject air into the accommodating cavity 303 through the air valve 305, forcing the pressure plate 302 to drag the outer mold shell 101 up through the load-bearing rod 301 under the action of air pressure, and the initial height of the outer mold shell 101 is corrected. While the outer mold shell 101 has a downward space during the production process, the top of the guide ear 306 is flush with the zero scale of the scale 308 to offset the initial gravity deviation caused by wear of the outer mold shell 101 and the inner mold base 102 during long-term use. In the preparation process of ecological bricks, the weight of the raw materials carried in the inner mold base 102 can be equivalently limited according to the indication of the scale 308, so as to cooperate with the compaction pressure to control the output quality of ecological bricks from multiple dimensions. Here, the gravity is defined as the output gram weight;

[0056] After completing the above adjustment work, connect the feed valve pipe 103 to the external raw material delivery pipeline, open the feed valve pipe 103, and feed the raw material slurry formed by mixing the construction waste particles and the corresponding auxiliary materials into the material barrel 201 through the feed valve pipe 103, and then start the air pump 221 to start the compression molding of the eco-bricks. Driven by the air pump 221, the external air is filtered by the filter box 2211 and then fed into the material barrel 201, causing the rotating wheel 216 to drive the bevel gear 218 to rotate accordingly under the action of air pressure, causing the shaft 217 to drive the toothed disc 219 to rotate accordingly, and the gear head 215 will also drag the piston plate 210 through the driving rod 214 as the toothed disc 219 rotates to reciprocate and rise and fall inside the transmission box 207;

[0057] During the descent of the piston plate 210 in the transmission box 207, the hydraulic fluid in the top chamber 2072 will be pressed into the upper chamber 2062 through the top connecting pipe 211, forcing the piston plate 210 in the material box 206 to rise under the action of the hydraulic pressure. During this process, the hydraulic fluid in the lower chamber 2061 will also be sent into the bottom chamber 2071 through the bottom connecting pipe 211 to fill the space expanded by the bottom chamber 2071 during the descent of the piston plate 210 in the transmission box 207. During the descent of the piston plate 210 in the transmission box 207, the hydraulic fluid in the bottom chamber 2071 will be pressed into the lower chamber 2061 through the bottom connecting pipe 211, forcing the piston plate 210 in the material box 206 to be pressed downward under the action of the hydraulic pressure. During this process, the hydraulic fluids in the top chamber 2072 and the upper chamber 2062 will be transferred in opposite directions accordingly.

[0058] During the rising process of the piston plate 210 inside the material box 206, negative pressure will be formed at the bottom of the piston plate 210 inside the lower chamber 2061. With the flow limiting and guiding function of the discharge valve 202, the raw material slurry inside the material barrel 201 will be drawn into the lower chamber 2061 through the conveying pipe 203. During the descending process of the piston plate 210 inside the material box 206, the raw material slurry drawn into the lower chamber 2061 will be pressed into the diverter seat 204 through the telescopic tube 205, and then injected into each mold cavity surrounded by the inner mold seat 102 and the outer mold shell 101 through the diverter seat 204. Then, as the piston plate 210 inside the material box 206 reciprocates and rises and falls, the raw material slurry inside the material barrel 201 is continuously pressed into each mold cavity surrounded by the inner mold seat 102 and the outer mold shell 101, and the raw material slurry is compression molded.

[0059] Similarly, during the descent of the piston plate 210 inside the transmission box 207, under the flow limiting effect of the check valve 212, the external air is filtered by the filter head 2121 and then drawn into the space outside the two piston plates 210 inside the transmission box 207, and then pressed into the barrel 201 through the three-pronged pipe 213, and the combined force of the airflow delivered by the air pump 221 drives the runner 216 to rotate. In this process, the ratio between the runner 216 and the bevel gear 218 is greater than the end surface area of ​​the piston plate 210 and the inclined surface area of ​​the runner 216, that is, during the rotation of the runner 216, the torque difference formed between it and the bevel gear 218 will amplify the pressure driving the runner 216 to rotate, and drive the piston plate 210 to reciprocate and rise and fall with the amplified pressure, and the piston plate 210 will press a larger volume of air into the barrel 201, and drive the runner 216 to rotate faster with a greater force, and then quickly amplify the pressure, providing the required pressure for the compression molding of the eco-brick;

[0060] In the above process, as the driving pressure is continuously added, the raw material slurry is continuously pressed into each mold cavity enclosed by the inner mold base 102 and the outer mold shell 101, and the hydraulic pressure of the hydraulic fluid will also rise synchronously. Under the conduction effect of the intermediate tube 310, the pressure on the top of the stop plug 312 will also rise synchronously. When the pressure on the top of the stop plug 312 is sufficient to offset the air pressure on the bottom, it means that the compacting pressure of the raw material slurry has reached the set value. At this time, the stop plug 312 drops under the pressure on the top, and the limit contact 314 will press the switch 314 driven by the sliding rod 313. 7. The switch 317 will send a signal to the outside to indicate that the compression molding of the raw material slurry inside the inner mold base 102 has reached the standard, and the connection between the side wall tube 311 and the middle tube 310 is turned on. During the lifting and lowering process of the piston plate 210 inside the transmission box 207, the hydraulic fluid inside the transmission box 207 will no longer flow into the lower chamber 2061 and the upper chamber 2062. Instead, it will be transferred between the bottom chamber 2071 and the top chamber 2072 through the side wall tube 311 and the middle tube 310. The piston plate 210 inside the material box 206 will no longer lift and lower, and the pressure delivery of the raw material slurry will be suspended;

[0061] In this process, the rotation of the rotating wheel 216 will also drive the stirring head 220 to rotate synchronously. On the one hand, the raw material slurry inside the barrel 201 can be stirred to further promote the mixing of the raw material slurry. On the other hand, the raw material slurry can be prevented from condensing, so that the slurry injected into the mold cavity before and after is uniform. After the raw material slurry is injected into each mold cavity surrounded by the outer mold shell 101 and the inner mold base 102, the gravity carried by the outer mold shell 101 will also increase accordingly, and then under the action of gravity, the outer mold shell 101 will drop accordingly. According to the readings of the scale 308 and the barometer 304, the parameters of the ecological bricks produced can be fine-tuned at the level of gram weight during the production process;

[0062] At this time, the air inside the flow cavity 315 is filled and released through the air nozzle 320, and the compacting pressure of the raw material slurry can be adjusted for the second time, thereby changing the raw material slurry injected into each mold cavity surrounded by the outer mold shell 101 and the inner mold base 102, and changing the material weight of the ecological brick. Under the compacting pressure and the diversion effect of the diverter seat 204, the raw material slurry will be evenly distributed to each mold cavity, which can ensure the consistency of the molding of the same batch of ecological bricks. This secondary adjustment can only be performed during the compression molding process of the first batch of ecological bricks in the same batch to ensure the output consistency of the same batch of ecological bricks.

[0063] By adjusting the compacting pressure and material weight between different batches, ecological bricks of different specifications can be produced.
