In sewage treatment, a smashing grille is commonly used, and the smashing grille effectively smashes the filtered garbage with large particle size while filtering the garbage with large particle size in sewage, so that the normal operation of the subsequent sewage treatment process is facilitated.

The prior unilateral smashing grille has the following problems in the use process:

1. because the solid garbage in the water is lighter, the filtered garbage with large particle size can be concentrated near the water surface at the two crushing rollers under the guidance of the guide grating and enter the two crushing rollers for crushing under the action of water flow and the two crushing rollers with special structures. However, when there is a large amount of waste in the water, the amount of waste concentrated in the vicinity of the two pulverizing rollers is increased rapidly, and the entire grating is blocked. Meanwhile, as the garbage is mostly located near the water surface, the water surface parts of the two crushing rollers can effectively crush the garbage, and the underwater parts of the two crushing rollers cannot be effectively utilized because the garbage cannot be effectively crushed, so that the crushing efficiency of the crushing rollers on the garbage is reduced.

2. The existing crushing grille moves internally and is provided with a shifting plate for cleaning the garbage filtered out and attached to the guide grille, the shifting plate can clean the guide grille along with the movement of the shifting plate after entering the grille, and the garbage is easily brought into the guide grille from the outside of the guide grille when the shifting plate is separated from the guide grille, so that the sewage treatment quality of the grille is reduced.

3. When the existing smashing grille is damaged or has a problem, water needs to be stopped for maintenance, on one hand, the efficiency of sewage treatment can be reduced due to maintenance, and on the other hand, the water is stopped, and related equipment for sewage treatment can be completely stopped for waiting for maintenance of the grille, so that various cost for maintaining the grille is increased.

The working flow of the invention is as follows: in the initial state, the sliding plate 62 is located outside the accommodating groove 4, the pressing mechanism 58 is installed between the top plate 9 and the bottom plate 1, all the pressing plates 65 are in a horizontal state and are abutted against the corresponding swing limiting plates B68, and the vortex springs 67 are in a compressed state. The L-bar 37 at the end of the filter tank 16, where the dial 31 is located, is located in a trigger slot 39 on the corresponding ring 38 and the corresponding limit lever 34 is in an unlocked state for the corresponding round pin 30. All leaf springs 32 are in compression. The L-bar 37, in which the pulling plate 31, which is not located at the end of the filter tank 16, is located, is not located in the trigger groove 39 on the corresponding ring 38 and the corresponding limit lever 34 is in a locked state with respect to the corresponding round pin 30. The baffle 54 is in an open state for the flow passage between the guide grill 15 and the side plate A6.

When the invention is needed to be used for filtering the garbage with large particle size in the sewage, the invention is hoisted and installed in the sewage pipeline through the hoisting ring 13. After the installation of the present invention is completed, the valve is opened so that sewage enters the pipeline and the motor A24 and the motor B53 in the present invention are started.

The motor a24 drives the rotation shaft a18 to rotate, the rotation shaft a18 drives all the shift levers 26 and all the arc plates 41 to synchronously rotate, each shift lever 26 drives a group of shift plates 31 hinged with the shift lever 26 to synchronously move, and the L-shaped rod 37 on each shift lever 26 moves along the cylindrical surface of the corresponding circular ring 38. The motor B53 drives the two rotating shafts B43 to synchronously and reversely rotate through the rotating shafts B43 and the gears A51 on the two rotating shafts B43, and the two rotating shafts B43 drive the two crushing rollers 44 to rotate.

Most of the sewage flow reaching between the side plate A6 and the side plate B8 is filtered by the filter grooves 16 on the guide grating 15, and the large-particle garbage is blocked outside the guide grating 15. The flow channel between the guide grating 15 and the side plate A6 forms water flow in the flow channel between the guide grating 15 and the side plate A6 due to the existence of the drainage groove 79, the water flow of the flow channel between the guide grating 15 and the side plate A6 drives the blocked large-particle garbage to move to the two crushing rollers 44 and the two crushing rollers 44 crush the arrived large-particle garbage, and the large-particle garbage is crushed into small particles to enter a pipeline for the treatment of one-step process.

When the rotating shaft a18 drives the corresponding set of shifting plates 31 to enter the corresponding set of filter tanks 16 through the shifting rod 26, the shifting plates 31 can shift the large-particle garbage which is filtered and blocked on the filter tanks 16 of the guide grating 15 and attached to the filter tanks 16 and effectively clean the filter tanks 16, so that the filter tanks 16 on the guide grating 15 are prevented from being blocked to reduce the filtering efficiency.

When the deflector 31 drives the garbage cleaned from the filter tank 16 to move to the flow channel between the guide grille 15 and the side plate A6, the water flow in the flow channel between the guide grille 15 and the side plate A6 will guide part of the garbage hooked on the deflector 31 to the two crushing rollers 44 for crushing.

When the shifting plate 31 rotates along with the rotating shaft A18 to reach the tail end of the filter tank 16, the L-shaped rod 37 on the shifting rod 26 enters the trigger groove 39 on the corresponding circular ring 38, and the limiting rod 34 is separated from the limiting groove on the corresponding round pin 30 under the action of the corresponding return spring 35 and unlocks the round pin 30. The paddle 31 swings under the action of the guide grill 15 as the rotation shaft a18 rotates, the corresponding leaf spring 32 is further compressed, and the garbage still hooked to the paddle 31 is scraped off by the end of the filter tank 16 and reaches the two pulverizing rollers 44 to be pulverized with the water flow of the flow path between the guide grill 15 and the side plate A6.

When the shifting plate 31 is separated from the tail end of the filter tank 16 along with the continuous rotation of the rotating shaft A18, the shifting plate 31 swings back and returns relative to the shifting rod 26 under the return action of the plate spring 32. After the dial plate 31 swings back and returns, the L-shaped rod 37 on the dial rod 26 corresponding to the dial plate 31 is separated from the trigger groove 39 on the circular ring 38 and is propped against the outer column surface of the circular ring 38, the L-shaped rod 37 drives the corresponding limiting rod 34 to be inserted into the limiting groove on the round pin 30 and lock the round pin 30 again, and the return spring 35 returns to the initial state.

The flowing water at the guide grille 15 will be disturbed as the flow rate of the flowing water changes as the arc plate 41 reciprocates on the rotating shaft a18, and the disturbed flowing water will further guide the garbage filtered and attached to the guide grille 15 into the flow passage between the guide grille 15 and the side plate A6.

Since the garbage reaching the two crushing rollers 44 is mostly concentrated near the top plate 9 due to the smaller specific density, the garbage concentrated near the top plate 9 is mostly concentrated near the top plate 9, so that the utilization rate of the two crushing rollers 44 under water is lower, and the crushing efficiency of the two crushing rollers 44 on the garbage is further reduced, and the garbage near the crushing rollers 44 is accumulated and cannot be timely scattered, crushed and discharged.

At this time, the motor C77 is started, and the motor C77 drives the slide plate 62 to vertically reciprocate through the gear E76, the gear D75, and the screw 74.

When the sliding plate 62 moves downwards, the sliding plate 62 drives all the racks B70 to move downwards vertically synchronously through the pressing plate 65 and the gear C69 because the friction strips 71 mounted on all the racks B70 and the guide plate 60 have larger friction force and all the pressing plates 65 are propped against the corresponding limiting plates. The pressing plate 65 kept horizontal presses down the garbage near the top plate 9 to the position in the water of the two pulverizing rollers 44, and the pressed garbage is efficiently pulverized by the position under the water of the two pulverizing rollers 44.

When the top plate 9 reaches the receiving groove 4 of the bottom plate 1 and is about to enter the receiving groove 4, the pressing plate 65 swings up under the action of the bottom plate 1 and moves into the receiving groove 4 along with the sliding plate 62, the vortex springs 67 are further compressed, and the pressing plate 65 drives the corresponding racks B70 to move downward relative to the sliding plate 62 through the gears.

When the pressing plate 65 completely enters the receiving groove 4, the pressing plate 65 is parallel to the slide plate 62. After all the pressing plates 65 enter the accommodating groove 4, the rubber film 78 at the notch of the accommodating groove 4 closes the accommodating groove 4 and prevents garbage from entering, at this time, the motor C77 drives the sliding plate 62 to move vertically upwards through a series of transmission, the pressing plates 65 keep to move upwards synchronously in parallel with the sliding plate 62 under the limitation of the accommodating groove 4, the pressing plates 65 drive the corresponding racks B70 to move synchronously through the gears C69, and the uppermost pressing plate 65 is separated from the accommodating groove 4 first.

When the pressing plate 65 is separated from the accommodating groove 4, the pressing plate 65 still keeps parallel to the sliding plate 62 due to friction between the friction strips 71 on the racks B70 and the guide plate 60, and the sliding plate 62 drives the corresponding racks B70 to synchronously move upwards through the pressing plate 65 and the gear C69. The pressure plate 65 at this time does not bring the trash in the water upward.

When the sliding plate 62 moves upwards to the limit, the motor C77 drives the sliding plate 62 to move downwards through a series of transmission, along with the downward movement of the sliding plate 62, the pressing plate 65 swings back and returns to the horizontal direction under the action of the friction strips 71 on the rack B70 and the guide plate 60 and the vortex springs 67, and keeps the horizontal state to move towards the containing groove 4 along with the continued downward movement of the sliding plate 62, and the pressing plate 65 in the horizontal state presses down the garbage near the top plate 9 into the water again, so that the garbage is crushed efficiently by the water parts of the two crushing rollers 44. When the pressing plate 65 reaches the receiving groove 4, it is folded again to be counted into the receiving groove 4. The garbage near the top plate 9 is pressed into the water for a large part to be effectively crushed by the underwater parts of the two crushing rollers 44, so that the garbage deposited near the top plate 9 is effectively cleaned while the garbage crushing efficiency of the two crushing rollers 44 is improved.

When the garbage near the top plate 9 is cleaned, the motor C77 drives the sliding plate 62 to move upwards to the limit and then drives the sliding plate 62 to move downwards by a small extent, so that the pressing plate 65 is restored to the horizontal state.

The probability of damage occurring after a long time has elapsed is greater due to the greater crushing strength of the two crushing rollers 44. A step of

When two crushing rollers 44 fail, the motor B53 is stopped, then the downward pressing mechanism 58 is detached, then the motor D57 is started, and the motor D57 drives the baffle plate 54 to move towards the side plate A6 through the gear B56 and the rack A55 and closes a flow passage between the guide grid 15 and the side plate A6, so that large-particle garbage in sewage can not enter the next process without being filtered.

Next, the two pulverizing rolls 44 and the two rotating shafts B43 are removed for maintenance, after the two pulverizing rolls 44 and the two rotating shafts B43 are installed after the maintenance is completed, the baffle plate 54 is driven by the start motor D57 to open the flow channel between the guide grille 15 and the side plate A6. Finally, the pushing mechanism 58 is reinstalled.

The closing of the flow passage between the guide grill 15 and the side plate A6 by the shutter 54 can keep the guide grill 15 of the present invention to continue filtering the sewage without stopping the water when the garbage cannot be crushed during the maintenance of the crushing roller 44, thereby improving the sewage filtering efficiency.

In summary, the beneficial effects of the invention are as follows: the garbage collected near the water surface is pressed into water through the reciprocating pressing mechanism 58, so that a large amount of garbage collected at the two crushing rollers 44 can be crushed by the two crushing rollers 44 efficiently, the overall utilization rate of the crushing rollers 44 is improved, the crushing efficiency of the garbage near the water surface of the two crushing rollers 44 is further improved, and the problem that the garbage collected at the crushing rollers 44 cannot be crushed and cleaned in time to block the guide grating 15 is avoided.

The invention effectively separates the garbage possibly hooked on the poking plates 31 through the swing of each poking plate 31 when the poking plates are separated from the guide grids 15, thereby avoiding that the poking plates 31 bring the garbage hooked by the poking plates 31 when the poking plates are separated from the guide grids 15. In the invention, two arc plates 41 which are circumferentially spaced 180 degrees apart on the rotating shaft A18 periodically disturb the water reaching the guide grating 15 in the process of rotating along with the rotating shaft A18, so that the water reaching the guide grating 15 can effectively crush the garbage filtered out and attached to the outer side of the guide grating 15 and the large-particle-size garbage floating in the water by moving to the two crushing rollers 44.

When the two crushing rollers 44 are damaged due to high working strength, the baffle plate 54 is driven by the motor D57 to close the channel formed by the guide grille 15 and the side plate A6 after the pressing mechanism is detached, and then the two crushing rollers 44 are detached for maintenance without stopping water, so that the invention temporarily loses the function of crushing garbage, but the invention can continue to filter sewage, and the sewage treatment work is ensured not to stop due to the maintenance of the invention.
