Description

Hydraulic pressing extrusion type impurity separation equipment for water-containing viscous sludge material

Technical Field

The invention relates to the technical field of impurity separation equipment in sludge, in particular to hydraulic pressing extrusion type impurity separation equipment for water-containing viscous sludge materials.

Background

At present, the building industry develops very rapidly and is an important prop industry of national economy. In the process of urban construction, a large amount of foundation engineering, such as building foundations, river dredging and the like, needs to be excavated, and soil excavated from the engineering is used as waste and is subjected to landfill or accumulation mountain-making treatment and the like. At present, the urban environmental protection policy is very strict, and the processing of landfill or accumulation of the excavated soil is not allowed, so the excavated soil needs to be subjected to secondary treatment. The content of impurities in soil excavated in some areas is low, and the soil is easy to treat; however, in southern coastal areas, the excavated soil has high organic matter content and water content, and has high viscosity and certain fluidity. Meanwhile, soil excavated in local regions in the south due to geographical factors has obvious characteristics, and the soil contains more impurities such as stones and the like, so that the soil is relatively difficult to treat.

In the existing treatment mode of the excavated sticky soil, research units can well go out when the excavated soil is used for manufacturing building materials, such as building bricks, building blocks, plates and the like. However, these treatments require high levels of clay impurities (especially rocks) and require that the size and weight ratio of the rocks be controlled within a range such that these clay impurities must be separated for further use.

At present, two ways are available for separating impurities in excavated viscous soil in the industry. One is a wet processing technology: adding water into the viscous soil material containing impurities, stirring into a fluid state, and separating water-insoluble impurities such as stones by using a screen. But the method has obvious defects, namely, the treatment process is more complex, more equipment is needed, and the occupied area and the investment are larger; secondly, a large amount of water is needed, secondary pollution is easy to cause, and the environment is not protected; thirdly, the cost of treatment is higher. The second way is dry process engineering: the impurities in the sticky soil are separated by directly utilizing the separation equipment. Compared with a wet treatment process, the treatment process has obvious advantages, but the existing dry treatment equipment is not reliable to use and has more defects.

The function of the pressing extrusion head assembly 4.3 with or without a sealing structure is to carry out extrusion impurity removal treatment on the impurity-containing sludge materials entering the sealing surface I6.2.2, the sealing surface II 6.2.5, the side baffle 7.2 and the middle baffle 7.4 of the double-station material box 7 of the equipment underframe 6, so as to separate impurities from the sludge.

The working principle of the whole equipment is as follows:

the initial position is: the complete push-down extrusion head assembly 4.3 composed of 16 groups is initially positioned in a pressure head guide hole 6.2.1 in a 6.2 portal frame of the equipment underframe 6, the piston rods of the oil cylinders 4.3.1.1 of each group are all retracted to the uppermost position, and the front end faces of the square extrusion heads or the three-section extrusion heads are flush. The space of the first feeding station of the double-station work box 7 is positioned below the position of the first feeding station of the feeding storage device 1, and the space of the second feeding station is positioned at the mud extruding station. Sealing doors 1.3 in the feeding and storing devices 1 of the left feeding station and the right feeding station are both in a closed state. The transverse pushing movable heads 2.1 in the transverse pushing impurity removing devices below the left feeding station and the right feeding station are in a retreating state. And the ejection beams 3.4 of the vertical top impurity removing devices below the left feeding station and the right feeding station are positioned at the bottommost part and are far away from the through hole grating 7.3.

The working process is as follows (whether the extrusion head assembly 4.3 is pressed down or not, the working process is the same):

the feeding equipment firstly feeds the impurity-containing sludge material to be processed into a sludge temporary storage hopper 1.2 in a feeding storage device 1 of a feeding station I, a sealing door 1.3 moves rightwards to the final position, the sludge temporary storage hopper 1.2 is communicated with a feeding station I space of a double-station material box 7, and the impurity-containing sludge material falls into the feeding station I space under the action of gravity. The sealing door 1.3 moves leftwards to the foremost position, the temporary sludge storage hopper 1.2 is separated from the space of the first feeding station of the double-station material box 7, and the sludge materials waiting for extrusion are temporarily stored in the space of the first feeding station.

The piston rods of two driving hydraulic oil cylinders 7.1 arranged on a movable platform 7.5 in the double-station material box 7 extend out below the feeding station, the piston rods of the other two driving hydraulic oil cylinders 7.1 arranged on the movable platform 7.5 in the double-station material box 7 are retracted below the feeding station II, the movable platform 7.5 moves to move the space of the feeding station I and sludge materials to be extruded in the space of the feeding station I to the extrusion station, and the space of the feeding station II moves to the space below the feeding station II.

The piston rods of the two hydraulic extrusion oil cylinders 5 do retraction movement to drive the downward-pressing movable beam 4.2 and a group of downward-pressing extrusion head assemblies 4.3 arranged on the downward-pressing movable beam to move downwards, and the impurity-containing sludge materials in the closed space formed by the space of the first feeding station, the first sealing surface 6.2.2 and the second sealing surface 6.2.5 are compressed and can only be extruded out of the holes in the through holes 7.3.1 in the through hole grid 7.3 and are discharged to the outside from the crushed sludge outlet under the action of gravity.

And when the extrusion station performs extrusion operation, the feeding station II performs feeding operation. In a sludge temporary storage hopper 1.2 in a feeding storage device 1 of a feeding station II, a sealing door 1.3 moves leftwards to the final position, the sludge temporary storage hopper 1.2 is communicated with a feeding station II space of a double-station work bin 7, and the material containing the impurity sludge falls into the feeding station II space under the action of gravity. The sealing door 1.3 moves rightwards to the foremost position, the space of the sludge temporary storage hopper 1.2 and the space of the feeding station II of the double-station material box 7 are separated, and the sludge materials waiting for extrusion are temporarily stored in the space of the feeding station II.

After the downward extrusion operation is completed at the extrusion station, the piston rods of the two hydraulic extrusion oil cylinders 5 do extension action to drive the downward movable beam 4.2 and a group of downward extrusion head assemblies 4.3 arranged on the downward movable beam to move upwards and retreat to the initial positions. And the feeding operation of the feeding station II is also finished. And under the second feeding station, piston rods of two driving hydraulic oil cylinders 7.1 arranged on a movable platform 7.5 in the double-station material box 7 are retracted, under the second feeding station, piston rods of the other two driving hydraulic oil cylinders 7.1 arranged on the movable platform 7.5 in the double-station material box 7 are extended, the movable platform 7.5 moves to move the space of the second feeding station and sludge materials to be extruded in the space of the second feeding station to an extrusion station, and the space of the first feeding station moves to the lower part of the feeding station, so that the feeding in the space of the first feeding station and the extrusion operation of the sludge in the space of the second feeding station are completed. This completes a complete cycle and all equipment returns to the initial state.

When no impurities exist in the sludge or the sizes of the impurities are smaller than the sizes of the holes of the through holes 7.3.1 formed in the through hole grating 7.3, piston rods of the two hydraulic extrusion oil cylinders 5 are retracted to reach the minimum leakage size, the front end faces of the 16 groups of downward pressing extrusion head assemblies 4.3 are moved downwards to positions close to the upper face of the through hole grating 7.3, and the oil distributing cylinders 4.3.1.1 in the 16 groups of downward pressing extrusion head assemblies 4.3 do not act in the whole process. The control PLC computer will control the 16 groups of pressing extrusion head assemblies 4.3 to return to the initial state to wait for the next compression process.

The piston rods of the two hydraulic extrusion cylinders 5 extend out to drive the front end faces of the 16 groups of downward extrusion head assemblies 4.3 to move downwards to compress sludge until impurities simultaneously contact the upper face of the through hole grating 7.3 and the front end faces of the downward extrusion head assemblies 4.3, and the impurities block the downward extrusion head assemblies 4.3 to move forwards continuously, so that the hydraulic oil pressure in the cylinder bodies of the two hydraulic extrusion cylinders 5 is increased, and when the set value is reached, the two hydraulic extrusion cylinders 5 stop moving forwards. At the moment, hydraulic oil is simultaneously supplied to the 16 oil distributing cylinders 4.3.1.1, all the lower pressing extrusion head assemblies 4.3 with impurities in the front and blocked do not move forwards due to the blocking effect of the impurities, and the lower pressing extrusion head assemblies 4.3 without impurities in the front are driven by the oil distributing cylinders 4.3.1.1 on the lower pressing extrusion head assemblies to move forwards continuously to compress sludge until the upper pressing extrusion head assemblies are close to the upper surface of the through hole grating 7.3. If there are small sized foreign objects blocking the advancing push down head assembly 4.3 during the advance, the blocked push down head assembly 4.3 will also stop advancing. When the pressure in all the oil cylinders 4.3.1.1 rises to the set value again, the whole compression process is finished, most of the sludge is discharged from the holes 7.3.1 of the through-hole grid 7.3, and a part of the sludge containing impurities with the sizes larger than the holes of the through-hole grid 7.3 is adhered to the upper surface of the through-hole grid 7.3 (or a part of the sludge enters the holes of the through-hole grid 7.3.1). The control PLC computer will control the 16 groups of pressing extrusion head assemblies 4.3 to return to the initial state to wait for the next compression process.

After the control PLC computer monitors that the pressure of hydraulic oil has the signal that the secondary rises to the setting value, will note that it is that there is impurity in this feeding station space, then before this space feeding next time, will control compound clear miscellaneous structure and carry out the feeding operation again after clearing up the operation to the impurity that has glued to above the through-hole grid 7.3 in this space earlier:

the first step is as follows: the plurality of liftout pieces 3.4.2 mounted on the movable beam 3.4.1 are driven by the piston rod of the hydraulic liftout cylinder 3.1 to move towards the through-hole grille 7.3 on the station and to be inserted into and pass through the through-holes 7.3.1, so that impurities (such as stones, branches and other impurities) adhered in the through-holes 7.3.1 are poked out from the sludge, and when the upper plane of the liftout piece 3.4.2 and the upper plane of the through-hole grille 7.3 are basically kept flat, the movement is stopped.

The second step is that: the motor speed reducer 2.4 rotates to drive the connecting shaft 2.6 and the fixed rack 2.5 arranged on the connecting shaft to rotate, the fixed rack 2.5 drives the fixed rack 2.5 fixed in the groove of the transverse pushing movable head 2.1 to move forwards, and impurities poked out of sludge on the through-hole grating 7.3 are discharged to a collecting device outside the equipment through the transverse pushing discharge hole 8.1 or the transverse pushing discharge hole 9.1.

The third step: and repeating the feeding operation procedure for the station.

If the PLC computer is controlled to monitor a signal that the pressure of the hydraulic oil is increased to a set value only once in the downward extrusion process, the composite impurity removing structure is controlled not to act, the cleaning operation is not carried out, and the first step and the second step do not act.

After a downward extrusion process or a feeding process with an impurity removing process is finished, if a PLC computer does not monitor a stop signal, whether each part is in an initial position or not is detected, and if the parts are in the initial positions, the feeding and compressing or impurity removing process is repeated. If the stop signal is available, the ongoing process is interrupted at any time, and the machine is stopped to be checked or stopped.
