Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
As shown in fig. 1 and fig. 2, an automatic impurity filtering device for roadway grouting reinforced cement-based slurry comprises a filtering box, an inner-layer filter screen, a collecting box and a cleaning device.
The filtering box is formed by welding steel plates, a round notch is formed in the bottom steel plate, threads are formed in the bottom steel plate, and the filtering box is connected with the collecting box. The filter cartridge is provided with a filter screen slot, a chute and a roller hole for the installation of subsequent parts.
The inner layer filter screen is woven by nylon ropes, the filter screens are installed in the slots, and the mesh number and the number of the filter screens are determined according to the actual situation on site.
The cleaning device is composed of a connecting rod, a roller with blades, a first group of driving wheels, a second group of driving wheels, a driving belt, a sliding groove and a hairbrush. The slurry flows into the filter box from the slurry inlet and impacts the roller with blades, and the roller drives the connecting rod to rotate. The first group of driving wheels on the connecting rod are connected with a belt to drive the second group of driving wheels in front to rotate together. One end of the connecting rod is connected with the edge of the second group of driving wheels, and the other end of the connecting rod is connected with a sliding block arranged in the sliding groove. The second group of driving wheels drive the small slide block to move up and down in the sliding groove while rotating. At the moment, the brush head of the brush connected with the sliding block is contacted with the filter screen and moves up and down along with the sliding block simultaneously so as to achieve the effect of cleaning the filter screen.
The concrete use steps of the automatic filter equipment of tunnel slip casting reinforcement cement base thick liquid impurity are as follows:
the device is connected between a grouting anchor rod and a grouting pipeline, and a grout inlet and a grout outlet are respectively connected by a hose in a sealing way. The valve is opened to allow the slurry to flow into the device. The slurry was filtered by impinging on a screen. Bigger granule adheres to on the filter screen, and the thick liquid after the filtration passes this device of filter screen outflow, accomplishes filtering so far. The particles adhered to the filter screen are accumulated for a long time to cause the problems of low filtering efficiency, poor filtering effect and the like caused by the blockage of the filter screen. Therefore, the device utilizes the kinetic energy of the slurry to design a self-cleaning device according to actual conditions. The principle is as follows: when slurry flows into the device, the slurry impacts the roller blades, and the first group of driving wheels coaxial with the roller blades drive the second group of driving wheels to rotate together through the driving belt. The edge of the second group of driving wheels is provided with a connecting rod, one end of the connecting rod rotates along with the second group of driving wheels, and the other end of the connecting rod moves up and down in the sliding groove. The brush head of the brush fixedly connected with the rod moves up and down along with the connecting rod and is contacted with the filter screen, so that the aim of cleaning the filter screen is fulfilled.
When a large amount of the filtered particles are deposited on the bottom, the valve can be closed to take down the collecting box, and the collecting box can be installed after being cleaned.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the present invention.
