Description

Technical Field

[0001] This utility model relates to the field of non-fired ceramic slurry injection technology, and specifically discloses a device for quantitative injection of non-fired ceramic slurry. Background Technology

[0002] Traditional ceramic production requires high-temperature firing in kilns, a process that consumes large amounts of energy (such as natural gas and electricity) and emits considerable amounts of carbon dioxide and harmful gases, which is inconsistent with the current trend of green and low-carbon industrial development. At the same time, various industrial solid wastes (such as waste ceramic powder, slag, and fly ash) and construction waste accumulate, occupying land and polluting the environment.

[0003] Currently, non-fired ceramic technology (also known as cold sintering technology) utilizes the principles of physical compaction and chemical polymerization to mold solid waste into ceramic products at room temperature or low temperature, offering significant advantages in energy saving and environmental protection. However, during the pouring process of non-fired ceramic slurry, common pouring methods often involve manually operating measuring cups or simple funnels for pouring. This results in poor quantitative accuracy, reliance on worker experience, inconsistent pouring volumes each time, large fluctuations in green body size, low product qualification rate, and slow manual operation speed, making it difficult to meet the needs of mass production. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0017] Please see Figure 1-3 A device for quantitative injection of non-fired ceramic slurry includes a base 1, a top plate 2 above the base 1, a mold 3 on the upper end surface of the base 1, and a quantitative injection mechanism on the lower end surface of the top plate 2. The quantitative filling mechanism includes a quantitative cylinder 4 located below the top plate 2 and having an open upper end. A push plate 5 is installed inside the quantitative cylinder 4, and a piston ring 6 is fixedly connected to the outer wall of the push plate 5. The lower end face of the quantitative cylinder 4 is connected to a filling nozzle 7 that matches the filling port of the mold 3. A through hole 8 is opened through the upper end face of the push plate 5, and a conveying pipe 9 connected to the through hole 8 is fixedly connected to the upper end face of the push plate 5. The upper end of the conveying pipe 9 extends to the top of the top plate 2 and is connected to an external non-fired ceramic slurry storage device.

[0018] In this embodiment: During injection, the first solenoid valve 10 is opened, and then the non-fired ceramic slurry is delivered into the metering cylinder 4 through the non-fired ceramic slurry storage device, the delivery pipe 9, and the through hole 8. At this time, the push plate 5 is located at the bottom inside the metering cylinder 4, so that the non-fired ceramic slurry is located below the push plate 5. Simultaneously, the first electric telescopic rod 12 drives the push plate 5 to move upward synchronously with the entry of the non-fired ceramic slurry. When the push plate 5 moves to the designated position, the push plate 5 stops moving, and at the same time, the injection of non-fired ceramic slurry into the metering cylinder 4 stops. At this time, the amount of non-fired ceramic slurry in the metering cylinder 4 is fixed, and the metering of the non-fired ceramic slurry is achieved by the position height of the push plate 5. Then, the first solenoid valve 10 closes, and multiple second electric telescopic rods 13 drive the metering cylinder 4 downward, so that the filling nozzle 7 is inserted into the filling port of the mold 3. Then, the second solenoid valve 11 is opened, and the first electric telescopic rod 12 drives the push plate 5 downward. The push plate 5 squeezes the non-fired ceramic slurry through the filling nozzle 7 and into the mold 3 through the piston ring 6. Then, the second solenoid valve 11 closes, and multiple second electric telescopic rods 13 drive the metering cylinder 4 to reset, thereby automatically and quantitatively filling the non-fired ceramic slurry, ensuring that the filling amount is consistent each time, improving the product qualification rate, and the automatic quantitative filling speed is fast, which can meet the needs of mass production.

[0019] As a technical optimization of this utility model, a first solenoid valve 10 and a second solenoid valve 11 are respectively installed inside the through hole 8 and the injection nozzle 7.

[0020] In this embodiment, the first solenoid valve 10 and the second solenoid valve 11 can respectively block the through hole 8 and the injection nozzle 7.

[0021] As a technical optimization of this utility model, a first electric telescopic rod 12 is installed on the upper surface of the top plate 2. The output end of the first electric telescopic rod 12 extends to the bottom of the top plate 2 and is fixedly connected to the push plate 5.

[0022] In this embodiment, the push plate 5 can be moved by the first electric telescopic rod 12.

[0023] As a technical optimization of this utility model, a plurality of evenly distributed second electric telescopic rods 13 are installed between the base 1 and the top plate 2.

[0024] In this embodiment, the top plate 2 and the metering cylinder 4 can be moved by multiple second electric telescopic rods 13.

[0025] As a technical optimization of this utility model, the section of the conveying pipe 9 located between the top plate 2 and the push plate 5 is configured as a telescopic flexible hose structure.

[0026] In this embodiment, the section of the conveying pipe 9 located between the top plate 2 and the push plate 5 is configured as a telescopic flexible hose structure, which allows the conveying pipe 9 to extend and retract with the movement of the push plate 5, preventing the conveying pipe 9 from affecting the movement of the push plate 5.

[0027] As a technical optimization of this utility model, the upper end of the metering cylinder 4 is fixedly connected with a plurality of arrayed connecting rods 14, and the other end of the plurality of connecting rods 14 is fixedly connected to the top plate 2.

[0028] In this embodiment, the metering cylinder 4 can be fixed by multiple connecting rods 14.

[0029] As a technical optimization of this utility model, the non-fired ceramic slurry storage device, the first solenoid valve 10, the second solenoid valve 11, the first electric telescopic rod 12, and the second electric telescopic rod 13 are all electrically connected to an external control computer.

[0030] In this embodiment, the computer facilitates the control of the non-fired ceramic slurry storage device, the first solenoid valve 10, the second solenoid valve 11, the first electric telescopic rod 12, and the second electric telescopic rod 13.

[0031] The working principle and usage process of this utility model are as follows: During pouring, the first solenoid valve 10 is opened, and then the non-fired ceramic slurry is conveyed into the metering cylinder 4 through the non-fired ceramic slurry storage device, the conveying pipe 9, and the through hole 8, so that the non-fired ceramic slurry is located below the push plate 5. At the same time, the first electric telescopic rod 12 drives the push plate 5 to move upward synchronously with the entry of the non-fired ceramic slurry. When the push plate 5 moves to the designated position, the push plate 5 stops moving, and at the same time, the addition of non-fired ceramic slurry into the metering cylinder 4 stops. At this time, the amount of non-fired ceramic slurry in the metering cylinder 4 is fixed, and then the push plate 5... The position height is used to quantitatively measure the non-fired ceramic slurry. Then, the first solenoid valve 10 is closed, and multiple second electric telescopic rods 13 drive the metering cylinder 4 downward to insert the pouring nozzle 7 into the pouring port of the mold 3. Then, the second solenoid valve 11 is opened, and the first electric telescopic rod 12 drives the push plate 5 downward. The push plate 5 squeezes the non-fired ceramic slurry through the pouring nozzle 7 and into the mold 3 through the piston ring 6. Then, the second solenoid valve 11 is closed, and multiple second electric telescopic rods 13 drive the metering cylinder 4 to reset, thereby automatically and quantitatively pouring the non-fired ceramic slurry.
