Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage filtration, in particular to a municipal drainage filtration device. Background Art

[0002] With the acceleration of the urbanization process, some problems such as urban water resource shortage, water environmental pollution, flood disasters and ecological environment deterioration have become very serious. As a key element in the water cycle system, rainwater plays an important role in the construction of a sustainable urban water cycle system. The drainage system in municipal engineering is divided into a rainwater drainage system and a sewage drainage system, and the rainwater in the rainwater drainage system is continuously discharged into the river. From the perspective of the water quality change of municipal rainwater, the initial rainwater contains ground pollutants (such as gasoline dripping from cars, chemical powders or liquids dropped during transportation, sediment, fine suspended solids, fallen leaves, domestic garbage, etc.), resulting in a relatively high concentration of suspended solids and poor water quality. Therefore, certain filtration is required in the existing technology for municipal drainage;

[0003] For example, a filtration device for municipal water supply and drainage disclosed in the utility model patent with the publication number CN211006999U includes a housing and a drain pipe. The housing is a hollow structure, and water inlets matching the drain pipe are provided on both side walls of the housing. The connection between the drain pipe and the housing is sealed. A filter screen plate is fixedly connected between the upper and lower inner walls of the housing. Through holes are provided on the side wall of the filter screen plate, and bearings are fixedly connected in the through holes. A rotating rod is arranged in the bearings. The rotating rod penetrates through the bearings and the through holes. One end of the rotating rod is fixedly connected with a propeller blade. Swing rods are rotatably connected to both side walls of the other end of the rotating rod away from the propeller blade through torsion springs. A brush head is fixedly connected to the end of the swing rod away from the torsion spring, and the side wall of the brush head abuts against the side wall of the filter screen plate. This utility model drives the propeller blade to rotate through the water flow in the drain pipe, so that the brush head brushes the filter screen plate. The structure is simple and the operation is convenient. However, the long-term impurity filtration action will cause excessive accumulation of impurities in the housing, which will affect the subsequent filtration effect of the filter screen plate. Excessive accumulation of impurities will cause water overflow, resulting in a poor filtration effect of the device. Therefore, the impurities need to be cleaned in time. For this reason, we propose a municipal drainage filtration device. Content of the Utility Model

Two symmetrically arranged guide posts 1004 are fixedly connected to the outer end of the pressing plate 1003.

[0027] Specifically, rotate the rotating handle 1006. At this time, the rotating handle 1006 drives the rotating rod 1002 to rotate, thereby driving the pressing plate 1003 to move outwards. At this time, the pressing plate 1003 drives the guide post 1004 to move outwards, thereby driving the limiting circular plate 1005 to move outwards. When the pressing plate 1003 no longer contacts the filter screen plate body 602 and the pressing plate 1003 disengages from the slot 14, the C-shaped plate 1001 can be rotated at this time.

[0028] In this embodiment, the outer peripheral side of each guide post 1004 is slidably connected to the C-shaped plate 1001 and the guide post 1004 penetrates the C-shaped plate 1001. A limiting circular plate 1005 is fixedly connected to the outer end of each guide post 1004.

[0029] Specifically, the setting of the limiting circular plate 1005 can complete the action of limiting the maximum position of the pressing plate 1003.

[0030] In this embodiment, the filter screen plate assembly 6 includes a limiting plate 601 slidably connected to the inner surface of the limiting groove 13. The outer end of the limiting plate 601 is fixedly connected to a filter screen plate body 602. Both sides of the end of the filter screen plate body 602 away from the limiting plate 601 abut against the inner surface of the slot 14.

[0031] Specifically, the filter screen plate body 602 is limited by inserting the limiting plate 601 into the limiting groove 13.

[0032] In this embodiment, an impurity storage box 11 is fixedly connected to the lower end of the processing box 1. The impurity storage box 11 is arranged on the left side of the filter screen plate assembly 6. The impurity storage box 11 is arranged on the right side of the cleaning plate 901. A discharge plate 12 is detachably connected to the lower end of the impurity storage box 11.

[0033] Specifically, the impurities stored in the magazine storage box can be unloaded by disassembling the discharge plate 12.

[0034] In this embodiment, the lower end surface of the cleaning plate 901 abuts against the inner lower end surface of the processing cavity 2. A drain pipe 3 is communicated with the lower side of the right end of the processing box 1.

[0035] Specifically, the drain pipe 3 can be used to discharge the water filtered out of impurities.

[0036] Working principle: Municipal drainage enters the treatment chamber 2 through the inlet 4 at the upper end of the treatment tank 1. After the water enters the treatment chamber 2, it first encounters the filter mesh plate assembly 6, which is composed of the filter mesh plate body 602 and the limiting plate 601. Through the fixation of the slot 14 and the limiting groove 13, the preliminary filtration of larger impurities in the water is realized. When the water flow passes through the filter mesh plate assembly 6, its kinetic energy is converted into mechanical energy. At this time, the water drives the blade 916 to rotate, thereby driving the third rotating shaft 915 to rotate. At this time, the third rotating shaft 915 drives the fourth pulley 914 to rotate. The fourth pulley 914 drives the third pulley 912 to rotate through the second belt 913. The third pulley drives the second pulley 909 to rotate through the second rotating shaft 910. The second pulley 909 drives the first pulley 907 to rotate through the first belt 908. The first pulley 907 drives the first rotating shaft 906 and the reciprocating lead screw 903 to rotate. The reciprocating lead screw 903 drives the scraper 917 to scrape the impurities on the surface of the filter mesh plate body 602. The reciprocating lead screw 903 drives the L-shaped push plate 902 to move back and forth. At this time, the L-shaped push plate 902 drives the cleaning plate 901 to reciprocate and push the impurities in the treatment chamber 2, thereby pushing the impurities into the impurity storage box 11. When it is necessary to clean and replace the filter mesh plate body 602, the turning handle 1006 can be rotated at this time. At this time, the turning handle 1006 drives the rotating rod 1002 to rotate, thereby driving the pressing plate 1003 to move outwards. At this time, the pressing plate 1003 drives the guide post 1004 to move outwards, thereby driving the limiting circular plate 1005 to move outwards. When the pressing plate 1003 no longer contacts the filter mesh plate body 602 and the pressing plate 1003 disengages from the slot 14, the C-shaped plate 1001 can be rotated at this time. Next, the filter mesh plate assembly 6 can be taken out of the slot 14 for replacement of the filter mesh plate assembly 6. This utility model realizes that the blocked impurities in the treatment tank 1 can be cleaned back and forth in time and fall into the impurity storage box 11, improving the smoothness of the treatment box and preventing the phenomenon of overflow during the drainage process of the treatment tank 1.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
