Description

Environment-friendly sewage treatment device

Technical Field

The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to an environment-friendly sewage treatment device.

Background

Sewage refers to waste water containing various wastes, organic matters, chemical substances, microorganisms, solid suspended matters, etc., which are generated from various living, industrial, agricultural and urban activities. The sewage has complex composition components including organic matters, solid suspended matters, chemical matters, microorganisms and the like. These components can pose a potential threat to the environment and human health and if discharged directly into the environment, can contaminate the water, soil and air, so existing wastewater discharge devices typically require filtration of the wastewater to protect the environment and human health.

The current device for filtering sewage is basically a grid or a filter screen which plays a main role component. The grating is typically composed of parallel arrangement of metal bars or fences, solid suspended matter is trapped in the grating gaps, and water flows out through the grating, which can be used to remove larger solid matter such as leaves, paper, plastic bags, etc. The filter screen is typically formed of metal bars or fences, with gaps generally smaller than the grids, to filter out smaller particles and solid suspensions, such as sand, dirt, gravel, etc. For example, chinese patent publication No. CN219259595U discloses an environmental protection sewage treatment device, which comprises a stirring tank, a settling tank is arranged below the stirring tank, the stirring tank is communicated with the settling tank through a connecting pipe, a fixing plate is fixedly installed on the outer side of the stirring tank, a diversion tank is fixedly installed on the outer side of the fixing plate, and a water inlet pipe is fixedly communicated with the upper surface of the diversion tank. The device is provided with the filter and places in the upper surface of loading board, and sewage can enter into the reposition of redundant personnel case through the inlet tube in, then in even flow to the inside of agitator tank for the filter plate can carry out filtration work to the great granule that contains in the sewage.

However, when the device is in actual use, because the large granule impurity that is filtered out can pile up on the surface of filter, because the device lacks the structure that integral type was clear away to large granule impurity again for it is difficult to discharge the large granule impurity that filters out and causes it to be deposited more, thereby causes the filtration pore to block up easily and influence the filtration to sewage, in order to prevent that above-mentioned condition from appearing, just need the operation personnel to regularly clear up the filter manually, not only troublesome, influence the normal use of device moreover.

In summary, there is a need for a sewage treatment device that can facilitate replacement of a filter screen and that does not affect normal use of the device during replacement.

Disclosure of Invention

The utility model aims to provide an environment-friendly sewage treatment device. The device is provided with two filter screens, when one filter screen works, the other filter screen is positioned at the outer side of the sewage treatment box body of the device so as to be convenient for cleaning; and the working state and the cleaning state of two filter screens are switched through the filter screen replacement assembly, the two filter screens are arranged side by side, when one filter screen is changed from the working state to the cleaning state, the other filter screen is automatically switched from the cleaning state to the working state, the whole replacement process does not need to be disassembled, and the operation process of the device is not influenced.

The utility model adopts the technical proposal that: an environment-friendly sewage treatment device comprises a treatment box, a filter screen replacement component and a filter screen cleaning component which are arranged on the treatment box, a water inlet pipe communicated with the top of the treatment box, and a water outlet pipe fixedly communicated with the bottom side of the treatment box;

the filter screen replacement assembly comprises a first filter screen movably connected inside the treatment box, a second filter screen fixedly connected with the first filter screen through a connecting block, a connecting plate fixedly connected with the side edge of the first filter screen, a switching screw rod arranged outside one side of the treatment box, a moving block screwed outside the switching screw rod, a connecting rod hinged between the moving block and the connecting plate, and a rotating wheel coaxially and fixedly connected with the bottom end of the switching screw rod.

Wherein, the effect of first filter screen and second filter screen lies in, when one of them filter screen during operation, and another filter screen is located the outside of device sewage treatment box to the clearance. This design makes the cleaning process more convenient and efficient. Namely, the filter screen replacement assembly achieves the effect of cleaning the unworked filter screen outside. The connecting plate has the function of driving the first filter screen and the second filter screen to move in the horizontal direction so as to finish the switching between the working state and the cleaning state. Wherein, remove the connecting plate through the runner, and then remove first filter screen and second filter screen, can make the filter screen of first filter screen and second filter screen different positions evenly wear out, prolong the holistic life of filter screen, reduce the damage that local wearing and tearing lead to design runner switching mechanism can make the change filter screen become more convenient, practices thrift maintenance time and human cost. In addition, the rotating wheel can be provided with a locking mechanism or is locked by the friction force existing in the switching screw rod, so that the stable position of the filter screen can be ensured, and the filter screen is prevented from being shifted or loosened due to long-time use, thereby improving the stability and reliability of the device.

The further preferable technical scheme is as follows: one side of the reciprocating screw rod is fixedly connected with a limiting rod and is in sliding connection with the scraping plate.

The further preferable technical scheme is as follows: the length of the scraping plate is consistent with that of the first filter screen.

Where consistent length refers to equal or very nearly equal lengths of different portions in a system or component. In a sewage treatment tank or filter system, if the length of the scraper is identical to the length of the first filter screen, it means that the length of the scraper matches or is very close to the length of the first filter screen. This design helps ensure that the blade is able to clean the filter screen completely.

The further preferable technical scheme is as follows: the outer end of the limiting rod is provided with a blocking piece.

Wherein, because the power of scraper blade comes from the decline process of sewage rivers, the decline of rivers has the randomness, and the scraper blade can break away from the risk of gag lever post completely like this, sets up the barrier at the outer end of gag lever post, can effectually be when the scraper blade is about to break away from the gag lever post completely, plays the barrier effect to it.

The further preferable technical scheme is as follows: the bottom end of the scraping plate is provided with a dirt removing block.

The dirt removing block gradually narrows along the direction of the extension of the scraping plate towards the filter screen, the design of the dirt removing block can help to remove residual sludge, solid particles and other impurities on the filter screen in the sewage treatment process, the dirt can be deposited on the water inlet side of the filter screen, and the shape of the dirt removing block can help to effectively remove the dirt, so that the normal operation of a treatment system is ensured. The gradually narrowing design of the dirt removing block can improve the cleaning effect of the filter screen, reduce the blocking risk of the filter screen and ensure the completion degree of the cleaning process.
