Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a mixing device for pouring uniform fluidized solidified soil. Background Technology

[0002] Fluidized solidified soil is made by mixing undisturbed soil, solidifying agent, and water as the main raw materials. It has the characteristics of excellent fluidity, self-compacting, and adjustable strength, and is widely used in engineering scenarios such as foundation pit backfilling, municipal pipeline backfilling, and soft soil foundation treatment. The mixing uniformity and stability of fluidized solidified soil directly determine the pouring construction quality and engineering effect.

[0003] Existing conventional fluidized solidified soil mixing equipment has many shortcomings in practical applications: Mixing operations are mostly semi-open, and dust and harmful volatile gases are generated during the mixing of soil and solidifying agent. These gases spread unorganized, polluting the environment and endangering the health of operators. The equipment operates noisily, lacks effective sound insulation and noise reduction structures, and the working environment is harsh. The equipment operates with large vibration amplitude and lacks a reliable shock absorption mechanism. The vibration exacerbates noise and affects the uniformity of material mixing, resulting in uneven pouring. The lack of targeted gas collection and purification components results in poor environmental performance and fails to meet the requirements of green construction.

[0004] Therefore, developing an integrated fluidized solidified soil mixing device that can achieve closed mixing, uniform stirring, low noise and vibration reduction, and exhaust gas purification is of great practical significance to this field. Summary of the Invention

The fan has its air inlet connected to the upper part of the mixing box via an air intake pipe, and its air outlet connected to the upper part of the purification box.

[0011] A further improvement of the present invention for the mixing device of uniform fluidized solidified soil is that the gas guiding structure includes a fan, which is connected to the upper part of the mixing box on the side relatively away from the suction pipe, and is used to actively blow the polluted gas accumulated in the upper part of the mixing box toward the suction pipe.

[0012] A further improvement of the present invention is that a heating pipe is provided on the inner wall of the mixing box to heat the material and improve the uniformity of the material mixing, and in conjunction with the gas guiding structure and the purification component, the purification efficiency of polluting gas is improved.

[0013] A further improvement of the present invention for the mixing device for pouring uniform fluidized solidified soil is that the base includes multiple legs, the vibration damping component includes multiple damping blocks, the multiple damping blocks are arranged in a one-to-one correspondence with the multiple legs, each damping block has an installation hole on its top, the legs are inserted into the installation holes, and a flexible buffer is provided between the legs and the bottom of the installation holes.

[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] The following detailed description of the mixing device for casting uniform fluidized solidified soil according to the present invention, with reference to the accompanying drawings and specific embodiments, will be provided in further detail.

[0023] Please see Figures 1-4 As shown, the mixing device for pouring uniform fluidized solidified soil includes: The mixing tank 2 is supported to the ground by the base 1. The mixing tank 2 is equipped with a mixing component for mixing materials. Vibration damping component 12 is connected to the bottom of the base 1 to reduce the vibration of the mixing tank 2; A noise reduction component is attached to the outside of the mixing chamber 2 to reduce the noise generated by material mixing; The purification component is connected to the upper part of the mixing tank 2 and is used to collect and purify the polluting gas generated by the mixing of materials. The mixing tank 2 is provided with a gas guiding structure to guide the polluting gas in the mixing tank 2 to the location of the purification component.

[0024] Specifically, the top of the mixing tank 2 is connected to an on / off feed hopper 13 for feeding materials, and the bottom of the mixing tank 2 is connected to a solenoid valve 14 for controlling the discharge of materials.

[0025] The openable and closable feed hopper 13 enables convenient and sealed feeding of materials, reducing dust spillage. At the same time, the solenoid valve 14 precisely controls the discharge on / off and discharge flow, thereby achieving orderly feeding and quantitative controllable discharge of materials, which is suitable for continuous mixing construction needs.

[0026] Preferably, the mixing assembly includes a mixing motor 3, a rotating rod 4, and mixing blades 5. The mixing motor 3 is installed on the top of the mixing tank 2, the rotating rod 4 extends into the interior of the mixing tank 2 and is connected to the mixing motor 3 for transmission, and the mixing blades 5 are connected to the rotating rod 4.

[0027] The stirring motor 3 drives the rotating rod 4 and stirring blades 5 to continuously stir the material, thereby achieving full mixing of the material and improving the uniformity of the mixing.

[0028] Specifically, the stirring blade 5 is provided with through holes spaced apart.

[0029] By opening through holes at intervals on the mixing blade 5, the mixing resistance of the blade can be reduced, and the energy consumption of the equipment can be reduced; at the same time, the material passes through the through holes to form a cross-flow turbulence, breaking up material clumps, thereby further improving the mixing uniformity of the fluidized solidified soil.

[0030] Preferably, the noise reduction component includes: Sound insulation cotton 6 is wrapped around the outer periphery of the mixing box 2 to reduce the noise generated by material mixing; A soundproof cover 7 is installed on the stirring motor 3 to reduce the rotation noise of the stirring motor 3.

[0031] Through dual sound insulation protection of the entire machine enclosure and the core sound source, the noise from mixing and impact, as well as the noise from motor operation, is blocked from spreading outwards, thereby significantly reducing the overall operating noise and effectively improving the working environment at the construction site.

[0032] Specifically, the mixing tank 2 has a viewing window 15 on its side wall for construction personnel to observe the mixing status of the materials, and the sound insulation cotton 6 has an opening at the viewing window 15.

[0033] By setting the viewing window 15 on the side wall of the mixing box 2, the mixing status of the materials in the box can be observed in real time, which facilitates timely adjustment of operating parameters; at the same time, the sound insulation cotton 6 has a corresponding reserved opening, which avoids structural interference while fully preserving the sound insulation and noise reduction performance of the whole machine, thus taking into account both the convenience of equipment observation and the effect of quiet operation.

[0034] Preferably, the soundproof cover 7 has multiple heat dissipation holes 16.

[0035] Through the heat dissipation holes 16 on the surface of the soundproof cover 7, the air circulation and heat dissipation inside the soundproof cover 7 are achieved while fully preserving the sound insulation and noise reduction capabilities. This prevents the accumulation of heat during the closed operation of the motor, prevents overheating and loss of the motor, and ensures long-term continuous and reliable operation of the equipment.

[0036] Preferably, the purification component includes: Purification box 9 is located on one side of mixing box 2. The purification box 9 has an activated carbon adsorption layer and an adsorption solvent layer arranged from top to bottom. The blower 10 has its air inlet end connected to the upper part of the mixing box 2 via the air intake pipe 11, and its air outlet end connected to the upper part of the purification box 9.

[0037] The negative pressure of the blower 10 actively extracts and transports the polluted gas generated during material mixing to the purification box 9. The gas then undergoes dual purification treatment, namely physical purification through the activated carbon adsorption layer and chemical purification through the adsorption solvent layer. This achieves efficient purification and clean emission of the polluted gas, prevents the unorganized diffusion of harmful gases, and meets the requirements of green and environmentally friendly construction.

[0038] Preferably, the gas guiding structure includes a fan connected to the upper part of the mixing tank 2, relatively away from the suction pipe 11, for actively blowing the polluted gas accumulated in the upper part of the mixing tank 2 toward the suction pipe 11.

[0039] The fan actively and directionally pushes the polluted gas accumulated in the upper part of the mixing box 2, eliminates the dead zone of airflow in the mixing box 2, and guides the polluted gas to accurately collect at the position of the suction pipe 11. In this way, together with the fan 10, the overall collection rate of polluted gas is greatly improved, and the residual and overflowing of polluted gas is avoided.

[0040] Preferably, the mixing chamber 2 is provided with a heating tube 8 on its inner wall to heat the material and improve the uniformity of the mixing, and in conjunction with the gas guiding structure and the purification component, improves the purification efficiency of polluting gases.

[0041] Heating tube 8 heats the material to reduce its viscosity, breaks up clumps, and improves the overall mixing uniformity. At the same time, it reduces the humidity inside the chamber, minimizing the interference of water vapor on the purification structure. This, combined with the gas guiding structure and purification components, forms a system synergy, further enhancing the final purification effect of polluted gas.

[0042] Preferably, the base 1 includes multiple legs, and the vibration damping assembly 12 includes multiple damping blocks 1201. The multiple damping blocks 1201 are arranged in a one-to-one correspondence with the multiple legs. Each damping block 1201 has a mounting hole 1202 at its top, and the leg is inserted into the mounting hole 1202. A flexible buffer 1203 is provided between the leg and the bottom of the mounting hole 1202.

[0043] Specifically, the vibration damping component 12 adopts a multi-point aligned independent vibration damping layout, with each outrigger individually equipped with a set of damping blocks 1201 and built-in flexible buffers 1203 to achieve full-point buffering and vibration damping of the entire machine.

[0044] The flexible buffer 1203 absorbs and counteracts the high-frequency vibrations generated during the mixing operation, preventing the vibrations from being transmitted and diffused to the ground, thus significantly reducing the shaking amplitude of the entire machine and improving the overall stability of the machine's operation. At the same time, it further ensures the stability of the mixing process and the uniformity of the output pouring.

[0045] Specifically, the flexible buffer 1203 is a high-damping composite buffer structure that combines load-bearing capacity with high-frequency shock absorption.
