RMT400 mud treatment equipment is a kind of pile foundation auxiliary equipment that serves as a supporting service for trench foundation construction, borehole foundation construction and non-excavation pile foundation construction machinery. It can effectively control the sand content in the construction mud and the particle precision in the slurry, separate the solid phase particles in the mud from solid to liquid, and dehydrate and discharge the separated waste residue. The equipment helps to increase the porosity of the pile foundation, reduce the cost of slurry used in the construction process, and realize the recycling of construction slurry. This type of equipment is widely used in underground diaphragm wall construction and deep hole drilling construction, especially in coastal areas or economically developed areas with high sand content in the formation, high environmental protection requirements for construction, and high mud treatment costs.

Technical advantages:

a) The whole machine is operated by electromechanical control buttons, which is extremely simple to use;

b) The compact structure is convenient for the transition use and installation of the equipment;

c) Low energy consumption and large processing capacity per unit time;

d) It can effectively control the cost of construction pulp and pulp making;

e) The solid-liquid separation performance is stable, and the sand content of the purified mud can meet the control standard for sand settlement at the bottom of the pile hole. The average particle size of the particles contained in the purified mud is d 50 <0.060mm;

f) It has two flow control functions, which can realize the internal fluid circulation after the external slurry supply is cut off, protect important components from damage, and can also realize the adjustment of the separation accuracy of thick slurry.

Technology Introduction:

The whole machine is composed of hydrocyclone, vibrating screen, slurry pump, box and electric control system.

Cyclone: ​​It is a multi-cone large-diameter hydrocyclone. This kind of hydrocyclone has a large processing capacity per unit time, and the lining is made of polyurethane material, which is wear-resistant and corrosion-resistant, and has high cyclone separation accuracy. The outer shell of the cyclone is made of homogeneous Q345B steel plate and has been sandblasted, which can protect the polyurethane material well, prevent the polyurethane material from premature aging caused by outdoor exposure, and help improve the quality of the cyclone. overall structural life.

Vibrating screen: including pre-screening and dewatering screen, the two vibrating screens work independently but have a common structure. They have the characteristics of wide adjustment range of exciting force, high dehydration rate of screen vibration, large output and low noise. The screen body is welded by Q345B homogeneous steel plate, with high structural strength and long service life. The dehydration sieve plate is made of polyurethane, and the pre-screen plate is made of spring steel. Both sieve plates are wear-resistant and corrosion-resistant, and are suitable for filtering waste residue and mud containing acid-base corrosive liquids.

Slurry pump: The self-developed special slurry pump is adopted. The pump has high conveying efficiency, stable liquid supply flow and head, and can effectively guarantee the use efficiency of the cyclone. High chromium alloy wear-resistant impeller and volute have the characteristics of high hardness and wear resistance. When filtering highly abrasive slurry, the service life is more than 2 times higher than that of ordinary cast steel impeller slurry pumps. The frame has strong bearing capacity and strong structural strength.

Box: The internal circulation system of the medium storage has two flow control functions, which can effectively adjust the working flow and pressure of the cyclone according to the concentration of the external feed material, and can realize backwashing inside the equipment to prevent thick slurry Precipitates inside the equipment. It can effectively avoid the occurrence of two serious accidents, such as thick slurry holding down the pump and equipment sucking air.

Electric control system:

a) Strong component compatibility and stable operation.

b) It has the function of exhaustion time - it is convenient for the timing maintenance of core components, which can effectively remind the key equipment of running exhaustion time, which is helpful for the maintenance of core components and prolongs the service life of equipment.

c) It has the function of delayed buffer start-it is convenient for the smooth start and stop of the vibrating screen

d) It has the function of continuous protection - to protect the main pump and prevent the reversal of power connection
