Description

Technical Field

[0001] The invention relates to the technical field of pressure tanks, in particular to a pressure grouting tank using negative pressure grouting. Background Art

[0002] The pressure grouting tank with negative pressure suction is an important equipment used in the fields of construction, engineering, geology, etc. It is mainly used to inject slurry (such as cement slurry, epoxy resin, chemical slurry, etc.) under pressure into underground structures, soil layers or concrete cracks that need to be reinforced, sealed or repaired. Its main function is to inject slurry into the target area under high pressure to achieve the purpose of reinforcement, waterproofing, plugging leaks or improving soil properties.

[0003] At present, the Chinese invention patent application with the publication date of September 20, 2024 and the publication number of CN 118668676A proposes a metal stamping equipment, including grouting equipment, pressure grouting system and air pump. The grouting equipment includes a drainage pipe and a grouting pipe passing through the inside thereof; one end of the grouting pipe extending into the permafrost melting interlayer at the lower part of the embankment is sleeved with a grouting bag, and the grouting bag is fixed by a clamp, and the other end is connected to a grouting connection pipe; the pressure grouting system includes a pressure grouting tank and a grouting tank inner bag embedded therein; the side wall of the pressure grouting tank is provided with an inflation nozzle; the opening of the grouting tank inner bag is sealed by a tank body sealing cover with a grouting nozzle; the grouting nozzle is connected to the grouting connection pipe; the air pump is connected to the inflation nozzle through an inflation pipe; the grouting bag and the grouting tank inner bag are filled with slurry. The present invention can quickly and efficiently realize the grouting reinforcement of the melted interlayer formed by the roadbed eroded by thermal melt disasters, and can also eliminate water disasters at the bottom of the roadbed and avoid soil pollution.

[0004] When pouring slurry into the tank manually, the pressure must be released before opening the lid, and the lid needs to be tightened with auxiliary tools. There is secondary pollution and air leakage that affect the slurry adding; the mouth of the 30-liter slurry adding tank is 1 meter from the ground, and the slurry adding port of the 100-liter pressure slurry adding tank is 1.3 meters from the ground. Adding slurry is inconvenient and there is a risk of spillage. At the same time, during the negative pressure slurry suction process, the slurry suction pipe may be blocked and worn. At the same time, the vibration of the pipe will cause the negative pressure environment to be unstable, and the vibration will cause pressure fluctuations, making it difficult to maintain the negative pressure at a stable level. This unstable negative pressure environment will directly affect the suction efficiency of the slurry, which may result in uneven slurry suction or insufficient slurry suction. Negative pressure fluctuations may also cause air to enter the pipe, forming bubbles, affecting the fluidity and quality of the slurry.

DETAILED DESCRIPTION

[0026] In order to reduce the possibility of manual spillage during the process of manually pouring slurry into the pressure grouting tank, and to reduce the technical problem of uneven slurry absorption during automatic suction, the embodiments of the present application provide the following solution.

[0027] Please also read Figures 1 to 5 An embodiment of the present application provides a pressure grouting tank using negative pressure grouting. The pressure grouting tank using negative pressure grouting includes a tank body 1, a slurry outlet 8, a connecting mechanism 2 and a pipeline mechanism 3. The slurry outlet 8 is arranged on the tank body 1, the connecting mechanism 2 is arranged on the tank body 1, and the pipeline mechanism 3 is arranged on the connecting mechanism 2.

[0028] In some embodiments, please refer to Figures 1 to 4 The connecting mechanism 2 includes a control component 21 and an operating component 22. The control component 21 includes a T-type manual three-way ball valve 211, a positive pressure device 212 and a vacuum device 213. A connecting air port is provided on the tank body 1. The T-type manual three-way ball valve 211 is arranged on the tank body 1 through the connecting air port. The positive pressure device 212 is arranged on the T-type manual three-way ball valve 211. The vacuum device 213 is arranged on the T-type manual three-way ball valve 211. The operating component 22 is arranged on the tank body 1 for realizing slurry suction under negative pressure. The operating component 22 includes an L-type three-way ball valve 221 and a safety valve 222. A slurry inlet 223 is provided on the tank body 1. The L-type three-way ball valve 221 is arranged on the tank body 1 through the slurry inlet 223. The safety valve 222 is arranged on the L-type three-way ball valve 221. The T-type manual three-way ball valve 211 is provided with a sensor 215.

[0029] With such arrangement, when the operator uses the pressure grouting tank to absorb slurry and add slurry, the operator manually places the valve core of the T-type manual three-way ball valve 211 in the vacuum device 213 and connects it to the connecting air port 214. The vacuum device 213 performs a vacuum operation on the tank body 1 to form a negative pressure state in the tank body 1. The L three-way ball valve is transferred to the slurry inlet 223 and connected to the pipeline mechanism 3 through the sensor 215 to realize negative pressure slurry absorption. When the valve core of the T-type manual three-way ball valve 211 is located in the positive pressure device 212 and connects it to the connecting air port 214, the positive pressure device 212 performs an inflation operation on the tank body 1 to form a positive pressure state in the tank body 1. The L three-way ball valve is transferred to the slurry inlet 223 and connects it to the safety valve 222 through the sensor 215, so as to facilitate the positive pressure slurry addition. Through the connection between the L three-way ball valve and the safety valve 222, The pressure in the tank body 1 is precisely controlled to ensure that it does not exceed the safe pressure range during the grouting process, thereby protecting the safety of equipment and operators. Through negative pressure grouting, the splashing and leakage of the slurry during the suction process can be effectively reduced, thereby reducing the risk of environmental pollution. The advantage of this solution is that it does not change the structure and configuration of the tank body 1. Only one L-type three-way valve and a T-type three-way valve need to be added to achieve negative pressure slurry suction and positive pressure slurrying. There are no major electrical and mechanical changes. This greatly improves the efficiency of slurrying, reduces the labor intensity of workshop operators, and reduces the risk of secondary contamination of slurry. By reasonably controlling the T-type manual three-way ball valve 211 and the L three-way ball valve, operators can achieve efficient, safe and precise operations during pressure grouting, thereby improving the overall construction quality and efficiency.

[0030] In some embodiments, please refer to Figures 1 to 5The pipeline mechanism 3 includes a hard pipe assembly 31 and a hose assembly 32. The hard pipe assembly 31 includes a connector 314, a first hard pipe 311, a second hard pipe 312 and a third hard pipe 313. The connector 314 is arranged on the L-shaped three-way ball valve 221. The first hard pipe 311 is arranged on the end of the connector 314 away from the L-shaped three-way ball valve 221. The second hard pipe 312 is arranged on the end of the first hard pipe 311 away from the connector 314. The third hard pipe 313 is sleeved on the end of the second hard pipe 312 away from the first hard pipe 311. The hose assembly 32 includes a hose 321, a first fixing ring 322, a second fixing ring 323 and a third fixing ring 324. The hose 321 is movably arranged on the third hard pipe 313. The first The fixing ring 322 is arranged on the hose 321, one end of the first fixing ring 322 abuts on the connecting head 314, the other end of the first fixing ring 322 abuts on the first hard tube 311, the second fixing ring 323 is arranged on the hose 321, one end of the second fixing ring 323 abuts on the first hard tube 311, the other end of the second fixing ring 323 abuts on the second hard tube 312, the third fixing ring 324 is arranged on the hose 321, one end of the third fixing ring 324 abuts on the second hard tube 312, the other end of the third fixing ring 324 abuts on the third hard tube 313, an anti-slip strip 325 is arranged on the hose 321, and a magnetic suction block 326 is arranged on the end of the hose 321 away from the third fixing ring 324.

[0031] With such arrangement, during the negative pressure slurry suction process, the first, second, and third hard tubes 313 and the connector 314 are used to support the fixing ring on the hose 321, so that hoses 321 of different diameters can be easily replaced. This design allows the operator to select a suitable hose 321 diameter according to the consistency of the slurry, thereby improving the slurry suction efficiency. The design of the hose 321 enables it to adapt to slurries of different consistencies, whether it is thin slurry or thick slurry, and can effectively perform slurry suction operations. The first, second, and third fixing rings 324 and the connector 314 provided on the hose 321 provide multi-level fixation, ensuring that the hose 321 will not fall off or shift due to vibration or pressure changes during the slurry suction process. The anti-slip strip 325 and the magnetic suction block 326 on the hose 321 further enhance the fixing effect. The anti-slip strip 325 can increase the friction between the hose 321 and the hard pipe to prevent the hose 321 from sliding; and the magnetic suction block 326 fixes one end of the hose 321 by magnetic force to ensure the stability of the overall structure. The hose 321 itself has a certain elasticity, which can effectively absorb and alleviate the vibration and impact generated during the slurry suction process. This shock absorption effect not only protects the equipment, but also reduces the impact of noise and vibration on the surrounding environment. The shock absorption effect helps to improve the comfort of the operator and reduce the fatigue caused by long-term operation. Due to the reasonable design of the connection between the hose 321 and the hard pipe, the removal and replacement of the hose 321 becomes simple and quick, which is convenient for daily maintenance and overhaul. By reasonably selecting the diameter and fixing method of the hose 321, the slurry can flow smoothly in the pipeline and improve the slurry suction efficiency. The multi-level fixing and shock absorption design can effectively prevent the hose 321 from falling off or bursting during the slurry suction process, ensuring the safety of the operation. In summary, this design combines flexibility, fixity, shock absorption effect and maintenance convenience, which can effectively improve the efficiency and safety of negative pressure slurry suction operation and extend the service life of the equipment.

[0032] In some embodiments, please refer to Figure 1 to Figure 2 The tank body 1 is provided with a connecting cover 4, and the connecting cover 4 is provided with a stirring assembly 5. The stirring assembly 5 includes a motor 51 and a stirring blade 52. The motor 51 is provided on the connecting cover 4, and the stirring blade 52 is provided on the motor 51. The stirring blade 52 rotates coaxially with the output shaft of the motor 51.

[0033] With this arrangement, the stirring blade 52 rotates coaxially with the motor 51 to ensure that the stirring force is evenly distributed inside the tank body 1. The power provided by the motor 51 is directly transmitted to the stirring blade 52, so that it can efficiently stir the slurry in the tank body 1 to avoid stratification or precipitation of the slurry and ensure the uniformity of the slurry. The rotation speed of the motor 51 can quickly drive the stirring blade 52 to stir, so that the slurry is fully mixed in a short time. This design is particularly suitable for occasions that require rapid mixing, such as construction sites or laboratories. The stirring component 5 is directly installed on the connecting cover 4, with a compact structure and small space occupation. This design makes the entire tank body 1 system more compact and convenient for use in limited space. The stirring assembly 5 is installed and used in a space, and the stirring assembly 5 is installed on the connecting cover 4. The disassembly and maintenance are relatively simple. When the stirring assembly 5 needs to be repaired or replaced, it is only necessary to disassemble the connecting cover 4, without disassembling the entire tank body 1, saving time and manpower. The stirring blade 52 rotates coaxially with the motor 51. The shape and angle of the stirring blade 52 can be optimized to adapt to different types of slurries and stirring requirements. Since the stirring blade 52 rotates coaxially with the motor 51, the stirring force directly acts on the slurry, reducing the stirring dead angle and unstirred area, ensuring that the slurry in the entire tank body 1 can be evenly stirred. The design of the stirring assembly 5 can adapt to slurries of different types and consistencies. By adjusting the speed of the motor 51 and the shape of the stirring blade 52, different stirring requirements can be met, and effective stirring can be achieved from thin slurry to thick slurry.

[0034] In some embodiments, please refer to Figure 1 to Figure 2 A bracket 6 is provided on the tank body 1, and the bracket 6 includes a fixing seat 61, a connecting strip and a universal wheel 63. The fixing seat 61 is provided on the tank body 1, the connecting strip is provided on the fixing seat 61, and the universal wheel 63 is provided on an end of the connecting strip away from the fixing seat 61. A connecting hole is provided on the tank body 1, and a visual window 7 is provided through the connecting hole.

[0035] With such arrangement, the universal wheel 63 can rotate freely 360 degrees on the horizontal plane, which allows the tank body 1 to be easily moved in different directions and adapt to various complex working environments. This design improves the maneuverability of the equipment, allowing the tank body 1 to be precisely operated in a small space, reducing the labor intensity of the operator and improving work efficiency. The design of the universal wheel 63 allows the tank body 1 to be flexibly moved and turned to adapt to different operating requirements and space limitations. The universal wheel 63 not only provides flexible mobility, but also ensures the stability of the equipment during movement to ensure safety. Through the support of the connecting strip and the fixed seat 61, the tank body 1 is not easy to tip over or slide during use, which increases the stability of the overall structure. The design of the visual window 7 allows the operator to observe the internal situation without opening the tank body 1, reducing operational risks and safety hazards. The visual window 7 allows the operator to monitor the status inside the tank body 1 in real time, such as liquid level, stirring conditions, etc., enhancing the functionality and practicality of the equipment. This design makes the tank body 1 not only a storage and stirring device, but also an observation and monitoring device. In summary, the design of the bracket 6 on the tank body 1 and the setting of the viewing window 7 provide many benefits such as mobility, flexibility, stability, safety, ease of operation, versatility, ease of maintenance and space utilization. This design not only improves the efficiency of the equipment, but also enhances the safety and convenience of operation.

[0036] The implementation principle of an air conditioning system in an embodiment of the present application is as follows: when an operator uses a pressure grouting tank to absorb slurry and add slurry, the operator manually places the valve core of the T-type manual three-way ball valve 211 in the vacuum device 213 and connects it to the connecting air port 214. The vacuum device 213 performs a vacuum operation on the tank body 1 to form a negative pressure state in the tank body 1. The L three-way ball valve is transferred to the slurry inlet 223 and connected to the pipeline mechanism 3 through the sensor 215 to realize negative pressure slurry absorption. When the valve core of the T-type manual three-way ball valve 211 is located in the positive pressure device 212 and is connected to the connecting air port 214, the positive pressure device 212 operates the tank body. 1 is inflated to form a positive pressure state in the tank body 1. The L three-way ball valve is turned to the slurry inlet 223 through the sensor 215 and connected to the safety valve 222, which facilitates the positive pressure slurry addition. Through the connection of the L three-way ball valve and the safety valve 222, the pressure in the tank body 1 can be accurately controlled to ensure that the safety pressure range will not be exceeded during the slurry addition process, thereby protecting the safety of equipment and operators. In the process of negative pressure slurry suction, the first, second, and third hard tubes 313 and the connector 314 are used to support the fixing ring on the hose 321, and the hose 321 of different diameters can be easily replaced. This design allows the operator to select a suitable hose 321 diameter according to the consistency of the slurry, thereby improving the slurry suction efficiency. The design of the hose 321 enables it to adapt to slurries of different consistencies, whether it is thin slurry or thick slurry, and can effectively perform slurry suction operations. The first, second, and third fixing rings 324 and the connector 314 provided on the hose 321 provide multi-level fixation to ensure that the hose 321 will not fall off or shift due to vibration or pressure changes during the slurry suction process. The anti-slip strip 325 and the magnetic block 326 on the hose 321 further enhance the fixing effect. The anti-slip strip 325 can increase the friction between the hose 321 and the hard tube to prevent the hose 321 from sliding; and the magnetic block 326 fixes one end of the hose 321 by magnetic force to ensure the stability of the overall structure. The hose 321 itself has a certain elasticity and can effectively absorb and alleviate the vibration and impact generated during the slurry suction process. After the slurry suction is completed, to avoid slurry stratification, the stirring blade 52 rotates coaxially with the motor 51 to ensure that the stirring force is evenly distributed inside the tank body 1. The power provided by the motor 51 is directly transmitted to the stirring blade 52, so that it can efficiently stir the slurry in the tank body 1, avoid slurry stratification or precipitation, and ensure the uniformity of the slurry. The rotation speed of the motor 51 can quickly drive the stirring blade 52 to stir.

[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
