Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flow state solidified soil preparation, more particularly, it relates to a high -efficient high -pressure type powder particle material feeding system. BACKGROUND

[0002] Since the flow state solidified soil method was proposed in the 1980s, the technology has been continuously improved and developed, and has become one of the most effective methods in the fields of trench backfilling, mine goaf backfilling, ground solidification and engineering waste slurry solidification. Especially in the projects of reclamation cofferdam and centralized solidification treatment of engineering waste slurry, engineering waste slurry or suction type slurry is often used as raw material to treat flow state solidified soil. Such projects usually need to treat a large amount of flow state solidified soil in a very short time, so the feeding system of the solidifying agent is required to be very high, and a high -efficient, fast powder particle material feeding system is needed to meet the demand of large -scale solidifying agent. The traditional solidifying agent feeding system usually uses vertical cement tank or ordinary cement tank, which has the following problems:

[0003] 1. Poor stability of vertical cement tank: the vertical tank needs higher foundation bearing capacity and ground flatness during installation, and has weak wind pressure resistance and low safety;

[0004] 2. Ordinary cement tank has insufficient high pressure resistance: the pressure resistance of ordinary cement tank is usually less than 1MPa, which cannot meet the demand of high pressure gas conveying powder particle material, resulting in low feeding efficiency;

[0005] 3. Limited conveying capacity of stirring cage: the traditional stirring cage has insufficient conveying capacity of powder particle material, which cannot meet the demand of large -scale flow state solidified soil treatment, especially in the scene of fast treatment of a large amount of solidifying agent, the conveying speed of the traditional system is far from enough.

[0006] In addition, the gas pressure of the traditional feeding system is usually maintained in the low pressure range of 0.2-0.4MPa, and the gas pressure is too high, which may cause damage to the equipment, and the gas pressure is too low, which will affect the conveying speed of the powder particle material, resulting in low feeding efficiency. Therefore, it is urgent to provide a high -efficient, high -pressure, simple and safe solidifying agent feeding system to meet the demand of large -scale flow state solidified soil treatment in modern engineering.

[0022] Reference Figs. 1 to 3 The embodiments of this utility model will be further described below.

[0023] A high-efficiency high-pressure powder material feeding system includes a horizontal storage tank, a 45KW air compressor, and a control system. The horizontal storage tank is 10.4m long, 2.55m wide, and 4m high. An air supply pipe is provided between the air compressor and the horizontal storage tank. The air supply pipe is a 1.5-inch diameter high-pressure hose. The other end of the horizontal storage tank is provided with an inlet / outlet structure, which includes an inlet pipe and an outlet pipe. The first end of the outlet pipe is connected to a fluidized solidified soil mixing device. The outlet pipe is a 4-inch diameter high-pressure corrugated pipe. The tail ends of the inlet pipe and the outlet pipe converge into a main pipe, which extends into the interior of the horizontal storage tank. The upper end of the horizontal storage tank is also provided with a tank outlet pipe, and the tail end of the outlet pipe is connected to a dustproof bag.

[0024] The control system includes an electrical control box for inputting required curing agent parameters, a solid flow meter for detecting the flow of solid material during conveying and calculating the material flow rate, a pneumatic actuator for controlling valve opening and closing and adjusting the curing agent delivery rate, and a controller for receiving standard current signals from the solid flow meter and driving the pneumatic actuator via electronic control circuitry. The solid flow meter is installed on the discharge pipe. The pneumatic actuator is an electronic pneumatic valve, located on the discharge pipe.

[0025] Working principle: first, the installation of the device, the horizontal storage tank is placed on the flat ground, to ensure the stability of the horizontal storage tank. Because the horizontal storage tank is designed horizontally, the wind resistance is good, and no special foundation treatment is required during installation; 45KW air compressor is installed near the horizontal storage tank, to ensure that the gas pipe can be connected to the horizontal storage tank smoothly; the gas pipe and the discharge pipe are connected to the horizontal storage tank and the fluidized soil mixing device respectively, to ensure that the connection is sealed well and prevent gas leakage; the electrical control box is installed at a position convenient for operation and connected to the control system. Solid flow meter and electronic pneumatic valve are installed on the discharge pipe.

[0026] In the feeding work, the valves on the inlet pipe and the tank gas pipe are closed, the valves on the gas pipe and the discharge pipe are opened, and the required curing agent and air compressor parameters such as flow, pressure, etc. are input on the operation surface of the electrical control box. Start the air compressor to generate 1.5MPa high pressure gas, which enters the horizontal storage tank through the gas pipe. The high pressure gas pushes the powder and particle materials in the tank, which are transported to the fluidized soil mixing device through the discharge pipe. The solid flow meter detects the flow of the material in real time and transmits the signal to the controller. The controller drives the pneumatic actuator through the electronic control circuit according to the received signal to control the opening and closing of the valve, so as to accurately control the input quantity of the curing agent.

[0027] In the storage state, the valves on the gas pipe and the discharge pipe are closed, the valves on the inlet pipe and the tank gas pipe are opened, and the powder and particle materials are fed to the inlet pipe by the transport vehicle. The powder and particle materials enter the horizontal storage tank for storage, and the air in the horizontal storage tank is discharged to the dust bag through the tank gas pipe. After the dust bag filters the powder and particle materials, the air is discharged externally, which is more environmentally friendly.

[0028] The system can process a large amount of powder and particle materials in a very short time or a short time, with a conveying capacity of up to 1800kg / min. It is easy to install and convenient to move, and is suitable for various site conditions. The horizontal storage tank has the advantages of good wind resistance, high pressure resistance, safe and reliable operation.

[0029] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiment. Any technical solution within the scope of the present application should be considered within the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application should also be considered within the protection scope of the present application.
