Description

Technical Field

[0001] This invention relates to the field of cement precast component processing, and in particular to an energy-saving cement precast component grouting device. Background Technology

[0002] In the construction industry, precast cement components are increasingly widely used due to their advantages such as high production efficiency and stable quality. Grouting, as a key step in the production of precast cement components, directly affects the quality and performance of the components.

[0003] Currently, traditional cement grouting devices have many shortcomings in practical applications. After the grouting device completes one cement mixing, the staff cannot know in time, which may lead to poor production process connection, reduced production efficiency, and even the degradation of cement grout performance due to failure to grout in time.

[0004] In addition, air bubbles are easily generated during cement mixing, and most traditional grouting devices do not have the function of pre-removing air bubbles. If these air bubbles are not dealt with in time, they will form pores inside the precast components, reducing the density and strength of the components and affecting their waterproof and impermeable properties. Subsequent vibration operations will require a long time, which in turn requires a lot of manpower, material resources and time. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving cement precast component grouting device. During use, this device can achieve thorough mixing of cement and will remind surrounding workers after each mixing is completed. In addition, during the mixing process, air bubbles in the cement can be removed, achieving the effect of pre-removing air bubbles and improving the efficiency of subsequent air bubble removal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An energy-saving precast cement component grouting device includes a support plate, a processing cylinder fixedly connected to the upper end of the support plate, a cement pump installed at the lower end of the support plate, the inlet end of the cement pump extending to the inner bottom of the processing cylinder, and the inner bottom surface of the processing cylinder being conical; a mixing mechanism, the mixing mechanism including a rotating rod rotatably connected to the top of the processing cylinder, a plurality of L-shaped stirring rods fixedly connected at equal intervals on one side of the rotating rod, each L-shaped stirring rod having its vertical part fixedly connected to its horizontal part by a reinforcing rod, an mounting frame installed at the upper end of the processing cylinder, a drive motor mounted on the mounting frame, the upper end of the rotating rod extending to the outside and being connected to the output shaft of the drive motor through a transmission component; and a negative pressure mechanism, the negative pressure mechanism being used to generate negative pressure inside the processing cylinder to reduce the gas content in the mixed cement.

[0008] Preferably, the processing cylinder has a feeding port at its inner top, and a sealing cap is installed at the feeding port.

[0009] Preferably, a plurality of support rods are fixedly connected to the lower end of the support plate, and a reinforcing plate is fixedly connected to the lower ends of the plurality of support rods.

[0010] Preferably, the negative pressure mechanism includes a connecting seat fixedly connected to the upper end of the processing cylinder, a piston cylinder fixedly connected to the upper end of the connecting seat, a first piston plate that can slide back and forth inside the piston cylinder, a driving disk fixedly connected to the upper end of the rotating rod, a connecting rod rotatably connected to the upper eccentric part of the driving disk, and the other end of the connecting rod rotatably connected to the front side of the first piston plate.

[0011] Preferably, the rear space of the piston cylinder is connected to the outside through a one-way port, and the one-way pipe of the rear space of the piston cylinder is connected to the inner top space of the processing cylinder.

[0012] Preferably, a second one-way valve is installed inside the one-way pipe, and a first one-way valve is installed inside the one-way port. The one-way flow direction inside the first one-way valve is to discharge the piston cylinder rear space to the outside in one direction, and the one-way flow direction inside the second one-way valve is to allow the processing cylinder to enter the piston cylinder rear space in one direction.

[0013] Preferably, an adjusting cylinder is fixedly connected to the left side of the processing cylinder, and a second piston plate that can slide left and right is provided inside the adjusting cylinder. The right side of the second piston plate is elastically connected to the right inner wall of the adjusting cylinder by a spring. The left side space of the adjusting cylinder is connected to the outside through a first connecting port, and the right side space of the adjusting cylinder is connected to the inner top space of the processing cylinder through a second connecting port.

[0014] Preferably, the right side space of the regulating cylinder is connected to the outside through an air intake pipe, a whistle is installed inside the air intake pipe, and a normally open solenoid valve is installed inside the air intake pipe. The normally open solenoid valve opens and closes synchronously with the drive motor.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows:

[0016] 1. The rotating rod and multiple L-shaped stirring rods are driven by the drive motor to rotate. The L-shaped stirring rods are reinforced to enhance stability. This can fully mix the raw materials and water in the treatment cylinder, making the cement slurry more uniform and helping to improve the quality and performance of cement precast components.

[0017] 2. When the rotating rod rotates, it drives the drive disc and connecting rod, causing the first piston plate to reciprocate, creating negative pressure inside the treatment cylinder, reducing the gas content in the cement, and achieving pretreatment. This reduces the difficulty of subsequent bubble removal, improves the density and strength of the components, and ensures the quality of the components.

[0018] 3. When the drive motor starts, the normally open solenoid valve opens; when mixing is finished, the drive motor stops and the solenoid valve closes. The negative pressure inside the processing cylinder allows outside air to enter the space on the right side of the regulating cylinder through the air inlet pipe. The air passes through the whistle and makes a sound, which can promptly remind the staff that mixing is complete and improve production efficiency.

[0019] 4. The regulating cylinder is made of transparent material. Users can judge the internal airtightness by observing whether the second piston plate moves to the left during the use of the device. This can detect airtightness problems in time and avoid the negative pressure mechanism from failing to operate normally due to poor airtightness, thus ensuring the stable operation of the device.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Reference Figures 1-5 An energy-saving precast cement component grouting device includes a support plate 1, a plurality of support rods 2 fixedly connected to the lower end of the support plate 1, a reinforcing plate 3 fixedly connected to the lower end of the plurality of support rods 2, a processing cylinder 4 fixedly connected to the upper end of the support plate 1, a feeding port 9 provided at the top of the inner side of the processing cylinder 4, a sealing cover 10 installed at the feeding port 9, a cement pump 20 installed at the lower end of the support plate 1, the inlet end of the cement pump 20 extending to the bottom of the inner side of the processing cylinder 4, and the inner bottom surface of the processing cylinder 4 being conical to facilitate the discharge of grout.

[0029] As one embodiment of the present invention, a mixing mechanism is also included. The mixing mechanism includes a rotating rod 17 rotatably connected to the top of the processing cylinder 4. A plurality of L-shaped stirring rods 18 are fixedly connected at equal intervals on one side of the rotating rod 17. The vertical part of each L-shaped stirring rod 18 is fixedly connected to its horizontal part by a reinforcing rod 19. A mounting frame 25 is installed at the upper end of the processing cylinder 4. A drive motor 26 is installed on the mounting frame 25. The upper end of the rotating rod 17 extends to the outside and is connected to the output shaft of the drive motor 26 through a transmission component. The mixing mechanism is used to mix the raw materials with water to form cement.

[0030] As one embodiment of the present invention, it also includes a negative pressure mechanism. The negative pressure mechanism is used to generate negative pressure inside the treatment cylinder 4 to reduce the gas content in the mixed cement and achieve the purpose of pretreatment. The negative pressure mechanism includes a connecting seat 5 fixedly connected to the upper end of the treatment cylinder 4. A piston cylinder 6 is fixedly connected to the upper end of the connecting seat 5. A first piston plate 8 that can slide back and forth is provided inside the piston cylinder 6. A drive disk 29 is fixedly connected to the upper end of the rotating rod 17. A connecting rod 7 is rotatably connected to the upper eccentric part of the drive disk 29. The other end of the connecting rod 7 is rotatably connected to the front side of the first piston plate 8. The rear space of the piston cylinder 6 is connected to the outside through a one-way port 12. A one-way pipe 14 in the rear space of the piston cylinder 6 is connected to the inner top space of the treatment cylinder 4. A second one-way valve 30 is installed inside the one-way pipe 14. A first one-way valve 13 is installed inside the one-way port 12. The one-way flow direction inside the first one-way valve 13 is to discharge the piston cylinder 6 rear space to the outside in one direction. The one-way flow direction inside the second one-way valve 30 is to allow the treatment cylinder 4 to enter the piston cylinder 6 rear space in one direction.

[0031] In one embodiment of the present invention, an adjusting cylinder 11 is fixedly connected to the left side of the processing cylinder 4. A second piston plate 16 that can slide left and right is provided inside the adjusting cylinder 11. The right side of the second piston plate 16 is elastically connected to the right inner wall of the adjusting cylinder 11 through a spring 23. The left space of the adjusting cylinder 11 is connected to the outside through a first connecting port 15. The right space of the adjusting cylinder 11 is connected to the inner top space of the processing cylinder 4 through a second connecting port 24. The right space of the adjusting cylinder 11 is connected to the outside through an air inlet pipe 21. A whistle 22 is installed inside the air inlet pipe 21. A normally open solenoid valve is installed inside the air inlet pipe 21. The normally open solenoid valve and the drive motor 26 open and close synchronously. Furthermore, the drive motor 26 can be synchronously controlled by an external program each time to achieve a fixed start time. The adjusting cylinder 11 can be a transparent cylinder. During the use of the device, the user can observe whether the second piston plate 16 moves to the left to judge the internal airtightness, so as to avoid the situation where the negative pressure mechanism cannot operate normally due to poor airtightness.

[0032] In this invention, the operator opens the sealing cover 10 at the feeding port 9, and feeds the raw materials and water into the processing cylinder 4 through the feeding port 9, then closes the sealing cover 10. Subsequently, the drive motor 26 on the mounting frame 25 is started, and the drive motor 26 drives the rotating rod 17 to rotate via a transmission component. When the rotating rod 17 rotates, multiple L-shaped stirring rods 18, which are fixedly connected at equal intervals on it, rotate accordingly. The vertical part of each L-shaped stirring rod 18 is fixedly connected to the horizontal part via a reinforcing rod 19, enhancing the stability of the stirring rod. During rotation, the L-shaped stirring rods 18 thoroughly stir and mix the raw materials and water in the processing cylinder 4 to form a cement slurry. Since the inner bottom surface of the processing cylinder 4 is conical, it facilitates the discharge of the mixed slurry.

[0033] While the rotating rod 17 rotates, the drive disc 29 fixedly connected to its upper end also rotates synchronously. The connecting rod 7 rotatably connected to the eccentric part of the upper end of the drive disc 29 drives the first piston plate 8, which can slide back and forth inside the piston cylinder 6, to reciprocate. When the first piston plate 8 slides forward, a negative pressure is formed in the space behind the piston cylinder 6. At this time, outside air cannot enter through the one-way port 12 (which is equipped with a first one-way valve 13, and the one-way flow direction is the one-way discharge of the space behind the piston cylinder 6 to the outside). However, the gas in the top space of the processing cylinder 4 enters the space behind the piston cylinder 6 through the one-way pipe 14 (which is equipped with a second one-way valve 30, and the one-way flow direction is the one-way entry of the processing cylinder 4 into the space behind the piston cylinder 6). When the first piston plate 8 slides backward, the gas in the space behind the piston cylinder 6 is discharged to the outside through the one-way port 12. This cycle is repeated, which generates a negative pressure inside the processing cylinder 4. Under negative pressure, the gas content in the cement will decrease, thereby reducing the gas content in the mixed cement and achieving the purpose of pretreatment.

[0034] When the drive motor 26 starts, the normally open solenoid valve installed inside the air intake pipe 21 opens synchronously; when the mixing process ends, the drive motor 26 stops working, and the normally open solenoid valve also closes; at this time, since the inside of the processing cylinder 4 is under negative pressure, outside air enters the right space of the regulating cylinder 11 through the air intake pipe 21; when the air passes through the whistle 22 inside the air intake pipe 21, the whistle 22 makes a sound to remind the surrounding staff that the cement mixing is complete; in addition, the regulating cylinder 11 is a transparent cylinder, and the user can observe whether the second piston plate 16 moves to the left during the use of the device to judge the internal airtightness, so as to avoid the situation where the negative pressure mechanism cannot operate normally due to poor airtightness; finally, the cement pump 20 is started to extract the mixed cement slurry in the processing cylinder 4 for grouting operation.
