For convenience, the upper portion of either belt is referred to as the upper belt 41 and the lower portion of either belt is referred to as the lower belt 42. The upper screen 20 is connected between a pair of upper belts and the lower screen is connected between a pair of lower belts.
Referring to fig. 1 and 2, initially, the upper screen 20 is positioned in the channel 12 of the waste water flowing through the hopper to filter the waste water flowing through, and the lower screen 30 is positioned on the side of the hopper 10 where the waste outlet 11 is located. Upper filter screen accumulation waste material reaches the certain degree, need the clearance, operator control drive belt mechanism's motor, 40 reverse drive of drive belt mechanism, lower floor's filter screen 30 comes to the waste water and flows through in the passageway 12 of feeder hopper, and upper filter screen 20 comes to the feeder hopper and is equipped with one side of waste outlet 11, upper filter screen only one end keeps being connected with upper drive belt, in order to be equipped with forward drive, the other end of upper filter screen inclines to waste outlet, dump the waste outlet with the waste material on it. Lower floor's filter screen 30 accumulation waste material reaches the certain degree, need clear up, operator control drive belt mechanism's motor, drive belt mechanism 40 forward drive, upper filter screen 20 comes to the waste water and flows through in the passageway 12 of feeder hopper, and lower floor's filter screen 30 comes the feeder hopper and is equipped with one side of waste outlet 11, lower floor's filter screen only one end keeps being connected with lower floor's drive belt to be ready for reverse drive, the lower floor's filter screen other end inclines to waste outlet, dump the waste outlet with the waste material on it.
With reference to fig. 3 to 6, the upper layer of filter screen 20 and the lower layer of filter screen 30 both include a plurality of filter screen units 21, each of the filter screen units includes a filter screen sheet 22, a filter screen frame 23 surrounding the filter screen sheet, sliders 24 fixedly connected to the left and right sides of the filter screen frame, and a pin 25 disposed on the sliders, the pin is fitted in a guide rail groove of a guide rail, and the guide rail is installed in the feed hopper 10; the sliding block of the upper layer filter screen is provided with a first meshing groove 240 meshed with the upper layer transmission belt 41, and the sliding block of the lower layer filter screen is provided with a second meshing groove meshed with the lower layer transmission belt 42; a plurality of filter screen units of upper filter screen are established ties through the steel sheet that can bend, and a plurality of filter screen units of lower floor's filter screen are established ties through the steel sheet.
Driven by the upper layer transmission belt 41, the slide block of the upper layer filter screen 20 moves forward and backward along the guide rail groove of the guide rail, when the slide block is moved to one side of the feed hopper where the waste material outlet 11 is arranged, because all the filter screen units are connected in series through the steel sheets capable of being bent, the filter screen unit separated from the guide rail droops under the action of gravity, the whole upper layer filter screen 20 only has one end matched with the guide rail, and is also kept meshed with the upper layer transmission belt 41, other filter screen units are abutted against the end parts of the adjacent filter screen units and pulled by the steel sheets, and are bent downwards or inclined, but cannot be twisted with each other, and the waste material on the upper layer filter screen units falls into the waste material outlet 11.
The slide blocks of the lower filter screen 30 are driven by the lower transmission belt 42 to move forward and backward along the guide rail grooves of the guide rail. When it is moved to the feeder hopper and is equipped with waste outlet 11 one side, because all filter screen units of lower floor's filter screen are established ties through the steel sheet that can bend, consequently, the filter screen unit that breaks away from with the guide rail is under the action of gravity, flagging, whole lower floor's filter screen 30, the filter screen unit of only one end still cooperates with the guide rail, and, still keep meshing with lower floor's drive belt 42, the reverse displacement of the follow-up lower floor's filter screen of being convenient for, other filter screen units, the tip of adjacent filter screen unit offsets, and is withheld by the steel sheet, be the form of bending downwards or slope, waste material on it falls into waste outlet 11. A waste collection container 60 is arranged below the waste outlet, as shown in fig. 1 and 2.
With reference to fig. 1 and fig. 2, the filter unit 21 at one end of the upper filter screen 20 is provided with a first limiting block 26, and the first guide rail 50 engaged with the upper filter screen is provided with a second limiting block 52 capable of abutting against the first limiting block. When the upper screen is used for dumping waste, only one screen unit at one end is matched with the first guide rail 50, and other screen units are separated from the first guide rail. If the first limiting block is not abutted against the second limiting block, the filter screen unit which is matched with the first guide rail can be separated from the first guide rail, so that the first limiting block and the second limiting block are necessary to be arranged. When the first stopper abuts against the second stopper, the filter screen unit engaged with the first guide rail is engaged with the upper layer transmission belt 41.
The filter screen unit of the lower filter screen 30 one end is equipped with the third stopper, is equipped with the fourth stopper that can offset with the third stopper on the second guide rail 500 with lower filter screen complex. When the waste material is dumped to lower floor's filter screen, only one filter screen unit of one end still cooperates with second guide rail 500, and other filter screen units break away from the second guide rail. If the third limiting block is not abutted against the fourth limiting block, the filter screen unit which is matched with the second guide rail is also separated from the second guide rail, so that the third limiting block and the fourth limiting block are necessary to be arranged. When the third limiting block is abutted to the fourth limiting block, the filter screen unit matched with the second guide rail is meshed with the lower-layer transmission belt 42, so that the lower-layer filter screen can be displaced reversely along the second guide rail conveniently.
