Description

Technical Field

[0001] This utility model belongs to the technical field of cement slurry mixing equipment, and relates to a slurry preparation and supply system for building construction. Background Technology

[0002] With the widespread application of embedded precast piles in engineering practice, the supporting construction equipment and technologies are also constantly developing. Among various pile-planting methods, some processes require the injection of cement grout during construction, traditionally relying on fixed cement grout mixing equipment for grout preparation. However, in situations involving frequent site changes, especially in linear, long-reaching projects such as highways and railways, fixed grout mixing equipment requires repeated disassembly, transportation, and reinstallation, resulting in long preparation times, high consumption of manpower and resources, and severely restricting overall construction efficiency.

[0003] Currently, there is a utility model patent with publication number CN219855244U entitled "A Mobile and Convenient Grouting Device for Construction Sites." This device integrates the equipment onto a mobile vehicle, enabling convenient transfer and alleviating some of the difficulties in moving the equipment. However, in practical applications, this device still has the following design flaws: the overall layout is not reasonable and compact enough, failing to fully utilize the vehicle space, resulting in an excessively large vehicle platform, making it difficult to move the device to confined spaces. Utility Model Content

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1 , Figure 2 As shown, a slurry preparation and supply system for building construction includes:

[0030] Pulping and storage equipment;

[0031] A powder silo 200 that supplies powder to the pulping and storage equipment;

[0032] A water tank 600 that supplies water to the pulping and storage equipment;

[0033] A mobile platform 110 that carries the pulping and storage equipment, the powder silo 200, and the water tank 600;

[0034] The pulping and storage equipment is located between the water tank 600 and the powder silo 200.

[0035] The moving mechanism 100 is equipped with a moving platform 110, which enables the entire system to be moved, facilitating transportation and deployment. The moving platform 110 serves as the mounting base for other components. The powder silo 200 stores dry powder (such as cement) and has at least one discharge port 210 through which the powder is discharged. The slurry storage tank 500 is located below the mixing tank 400. The cement slurry in the mixing tank 400 can directly enter the slurry storage tank 500 under gravity, eliminating the need for an additional slurry pump. The water tank 600 stores and supplies water required for mixing.

[0036] The mobile mechanism 100 is preferably a vehicle, with the vehicle's body serving as a mobile platform 110. The vehicle, such as a truck or trailer, has a chassis and wheels, allowing it to travel on roads. The mobile platform 110 allows for direct mounting of various components. This vehicle-like design improves mobility and is suitable for engineering sites such as railways and highways.

[0037] The pulping and storage equipment is located between the water tank 600 and the powder silo 200. Both the powder silo 200 and the water tank 600 can be transported to the pulping and storage equipment via the shortest path. The overall layout can make full use of the space of the mobile platform, making the overall structure compact and easy to make the mobile platform smaller, which is suitable for flexible movement and arrangement in narrow construction areas.

[0038] like Figure 1 , Figure 2 As shown, based on the above embodiments, the pulping and storage equipment includes a mixing tank 400 and a storage tank 500. The mixing tank 400 and the storage tank 500 are arranged vertically correspondingly, and the outlet of the mixing tank 400 is connected to the inlet of the storage tank 500.

[0039] Preferably, the mixing tank 400 includes a tank body, a mixing motor, and a mixing paddle. The mixing paddle extends into the tank body, and the mixing motor is connected to the mixing paddle. The tank body is used to receive the powder in the powder hopper 200 and provide a container space for mixing. The mixing motor is located outside or on top of the tank body to provide power. The mixing paddle is driven to rotate by the mixing motor to mechanically mix the powder and water to form a uniform slurry.

[0040] Based on the above embodiment, a delivery pump 700 is also included, which is installed on the mobile platform 110 to output the prepared slurry from the slurry storage tank 500. The delivery pump 700 is installed on the mobile platform 110 and is located below the water tank 600. The delivery pump 700 is connected to the slurry outlet of the slurry storage tank 500. The delivery pump 700 is used to pump the cement slurry in the slurry storage tank 500 to the point of use (such as a grouting pipeline).

[0041] Based on the above embodiment, a feeding mechanism 300 is also included, which extends obliquely upward from below the powder silo 200 to the inlet of the mixing tank 400. The feeding mechanism 300 is used to continuously and uniformly transport powder from the powder silo 200 to the mixing tank 400. The mixing tank 400 is the preparation site for cement slurry.

[0042] Preferably, the feeding mechanism 300 is configured as a screw feeder, which includes a material cylinder, a conveying motor and a screw shaft. The material cylinder inlet is located below the material outlet 210 of the powder silo 200, and the material cylinder outlet is located above the mixing tank 400. The screw shaft is located inside the material cylinder, and the conveying motor is connected to the screw shaft.

[0043] The screw shaft can rotate under the drive of the conveyor motor, thereby propelling the powder forward. In actual use, the conveying pipe feeds the powder into the mixing tank 400, which works in conjunction with the water tank 600 to supply water, thus achieving automatic batching.

[0044] Preferably, the powder silo 200 is configured as a horizontal powder tank with multiple discharge ports 210, and each discharge port 210 is arranged sequentially on the conveying path of the feeding mechanism 300. Each discharge port 210 is connected to the feeding mechanism 300, which can effectively increase the discharge points and make the powder discharge more uniform and smooth.

[0045] Based on the above-described embodiment, a generator set 900 is also included. The generator set 900 is mounted on the mobile platform 110. The slurry preparation and storage equipment, the water pump of the water tank 600, the conveying pump 700, and the feeding mechanism 300 are all electrically connected to the generator set 900. The generator set 900 is preferably a diesel or gasoline generator, which provides power to the entire system, drives the feeding mechanism 300, the stirring motor, the conveying pump 700, etc., ensuring power supply and enabling the system to operate independently without external power.

[0046] like Figure 1 , Figure 2 As shown, based on the above-described embodiment, it also includes an operation room 800, which is located on the mobile platform 110. The water tank 600 is located on the top of the operation room 800, and the delivery pump 700 is adjacent to the operation room 800 and located within the observation range of the operation room 800.

[0047] The control room 800 is a closed or semi-closed space containing control panels, instruments, etc., for operators to monitor and operate the system. The water tank 600 is located on top of the control room 800, saving space through this vertical layout and making the system more compact. The water tank 600 shelters the transfer pump 700 from the open environment, providing protection. The transfer pump 700 is adjacent to the control room 800, ensuring that operators can directly observe its operating status through windows or openings and promptly address any abnormalities.

[0048] The control room 800 is located in the space below the water tank 600 and next to the transfer pump 700, a reasonable layout. Operators can operate safely from inside and have a clear view of the transfer pump 700's operation. The water tank 600 provides physical protection for the transfer pump 700, preventing external impacts or environmental influences.

[0049] Based on the above implementation method, a control valve is provided in the passage between the outlet of the mixing tank 400 and the inlet of the slurry storage tank 500, and the control valve is electrically connected to the control room.

[0050] It should be noted that the mobile platform 110 includes a first position 111, a second position 112, and a third position 113 arranged sequentially and adjacently along its length. The operating room 800, the conveying pump 700, and the water tank 600 are all located at the first position 111, the mixing mechanism and the slurry storage tank 500 are all located at the second position 112, and the powder silo 200 and the feeding mechanism 300 are all located at the third position 113.

[0051] The first position 111 is used to centrally arrange the operating room 800, the conveying pump 700, and the water tank 600. The second position 112 is used to arrange the mixing mechanism and the slurry storage tank 500, and the vertical layout saves space in the length direction. The third position 113 is used to arrange the powder silo 200 and the feeding mechanism 300. This partitioned layout makes the layout of this system more reasonable and makes full use of the space on the mobile platform 110.

[0052] The system works as follows: Powder falls from the powder silo 200 through the discharge port 210 into the feeding mechanism 300, which then conveys the powder through the conveying pipe 310 into the mixing tank 400. Simultaneously, the water tank 600 supplies water to the mixing tank 400. The mixing mechanism mixes the powder and water into a uniform cement slurry. After mixing, the cement slurry flows by gravity from the mixing tank 400 into the storage tank 500 below. The delivery pump 700 extracts the cement slurry from the storage tank 500 and pumps it to the required location.

[0053] The pulping (mixing mechanism) and pulp storage tank 500 are arranged vertically (mixing tank 400 is on top of pulp storage tank 500), making full use of gravity to allow the slurry to flow by gravity, eliminating the need for an additional slurry pump and saving energy and space. Vertical space utilization allows the platform to accommodate a larger powder silo 200 along its length, increasing powder storage capacity. The water tank 600 is positioned above the delivery pump 700, providing shelter and protection while also facilitating operator observation of the pump's operation.

[0054] The system operates as follows: The system is moved to the construction site by vehicle. A generator set 900 provides power (or an external power source). Operators start the system from the control room 800. Multiple discharge ports 210 at the bottom of the powder silo 200 (horizontal powder tank) open as needed, allowing the powder to fall into the screw feeder by gravity. The screw feeder's motor drives the screw shaft to rotate, continuously feeding the powder into the mixing tank 400 through the conveying pipe 310. The multiple discharge ports 210 ensure smooth powder discharge without jamming. The water tank 600 supplies water to the mixing tank 400 via pipes or a water pump. Water and powder are mixed in the mixing tank 400 by a mixing impeller driven by a mixing motor, forming a uniform cement slurry. The mixing time can be set from the control room 800 as needed. After mixing, the control valve opens, and the cement slurry flows by gravity from the bottom of the mixing tank 400 into the storage tank 500 below. The vertical layout of the slurry preparation and storage saves space, eliminates the need for an additional slurry pump, and reduces energy consumption and equipment costs. The delivery pump 700 (located below the water tank 600) draws cement slurry from the slurry storage tank 500 and pumps it into the grouting pipeline or the point of use. The water tank 600 provides shelter and protection for the delivery pump 700 and is located within the observation range of the control room 800 for easy monitoring.

If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
