Description

Technical Field

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

[0002] In the construction industry, cement precast components are increasingly used due to their advantages of high production efficiency and stable quality. Grouting is a key step in the production of cement precast components, and its effect 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 a cement mixing, the staff cannot know in time, which may lead to poor connection of production processes, reduced production efficiency, and even the deterioration of cement slurry performance due to failure to grout in time.

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

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and propose an energy-saving cement prefabricated component grouting device. When in use, the device can achieve sufficient mixing of cement and will remind surrounding staff after each mixing is completed. In addition, during the mixing process, bubbles in the cement can also be removed to achieve the effect of pre-debubbling and improve the efficiency of subsequent bubble removal.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The mixing mechanism comprises a rotating rod rotatably connected to the top of the processing cylinder, and a plurality of L-shaped stirring rods are fixedly connected to one side of the rotating rod at equal intervals, and each of the L-shaped stirring rods has a vertical portion fixedly connected to its horizontal portion by a reinforcing rod, and a mounting frame is installed at the upper end of the processing cylinder, and a driving motor is installed on the mounting frame, and the upper end of the rotating rod extends to the outside and is connected to the output shaft of the driving motor through a transmission member; a negative pressure mechanism, and the negative pressure mechanism is used to generate negative pressure inside the processing cylinder to reduce the gas content in the mixed cement.

[0008] Preferably, a feeding port is provided at the inner top of the processing cylinder, and a sealing cover 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 together.

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

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

[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 that the rear side space of the piston cylinder discharges unidirectionally to the outside, and the one-way flow direction inside the second one-way valve is that the processing cylinder enters the rear side space of the piston cylinder unidirectionally.

[0013] Preferably, an adjusting cylinder is fixedly connected to the left side of the processing cylinder. A second piston plate that can slide left and right is arranged in the adjusting cylinder. The right side of the second piston plate is elastically connected to the right inner wall of the adjusting cylinder through a spring. The left side space of the adjusting cylinder is communicated with the outside through a first communication port, and the right side space of the adjusting cylinder is communicated with the inner top space of the processing cylinder through a second communication port.

[0014] Preferably, the right side space of the adjusting cylinder is communicated with the outside through an air inlet pipe. A wind whistle is installed inside the air inlet pipe, and a normally open solenoid valve is installed inside the air inlet pipe. The normally open solenoid valve is opened and closed synchronously with the driving motor.

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

[0016] 1. By driving the driving motor to drive the rotating rod and a plurality of L-shaped stirring rods to rotate, and the L-shaped stirring rods are strengthened by reinforcing rods to enhance stability, the raw materials and water in the processing cylinder can be fully stirred and mixed, making the uniformity of the cement slurry better, which helps to improve the quality and performance of the cement precast components;

[0017] 2. When the rotating rod rotates, it drives the driving disk and the connecting rod, making the first piston plate reciprocate, generating negative pressure inside the processing cylinder, reducing the gas content in the cement, realizing pretreatment, which can reduce the difficulty of removing subsequent bubbles, improve the density and strength of the components, and ensure the quality of the components;

[0018] 3. When the driving motor starts, the normally open solenoid valve opens. When the mixing is completed and the driving motor stops, the solenoid valve closes. The negative pressure in the processing cylinder causes the outside air to enter the right space of the adjustment cylinder through the air inlet pipe. The air makes a sound through the whistle, which can timely remind the staff that the mixing is completed and improve production efficiency.

[0019] 4. The adjustment cylinder is made of a transparent cylinder. During the use of the device, the user can judge the internal airtightness by observing whether the second piston plate moves leftward. This can timely detect airtightness problems, avoid the abnormal operation of the negative pressure mechanism due to poor airtightness, and ensure the stable operation of the device.

The one-way flow direction inside the first one-way valve 13 is that the rear space of the piston cylinder 6 is discharged to the outside world in one direction, and the one-way flow direction inside the second one-way valve 30 is that the treatment cylinder 4 enters the rear space of the piston cylinder 6 in one direction;

[0031] As an implementation manner of the present invention, a regulating 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 arranged in the regulating cylinder 11. The right side of the second piston plate 16 is elastically connected to the inner wall of the right side of the regulating cylinder 11 through a spring 23.

During the use of the device, the user can observe whether the second piston plate 16 moves left to judge the airtightness inside, so as to avoid the situation that the negative pressure mechanism cannot operate normally due to poor airtightness.

[0032] In the present invention, the staff opens the sealing cover 10 at the feeding port 9 and inputs the raw materials and water into the processing cylinder 4 through the feeding port 9, and 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 through a transmission member; when the rotating rod 17 rotates, a plurality of L-shaped stirring rods 18 fixedly connected at equal intervals thereon rotate accordingly, and the vertical part of each L-shaped stirring rod 18 is fixedly connected to the horizontal part through a reinforcing rod 19, enhancing the stability of the stirring rod; during the rotation of the L-shaped stirring rod 18, the raw materials and water in the processing cylinder 4 are fully stirred and mixed to form cement slurry; since the inner bottom surface of the processing cylinder 4 is a conical surface, it is beneficial to the discharge of the mixed slurry;

[0033] While the rotating rod 17 is rotating, the drive disk 29 fixedly connected to the upper end thereof also rotates synchronously; the connecting rod 7 rotatably connected to the eccentric position at the upper end of the drive disk 29 drives the first piston plate 8 that can slide back and forth in the piston cylinder 6 to perform a reciprocating motion back and forth; when the first piston plate 8 slides forward, a negative pressure is formed in the rear space of the piston cylinder 6.
