Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a municipal sewage treatment device. Background Art

[0002] Municipal sewage is a mixture of domestic sewage, industrial wastewater and urban rainfall runoff within the urban area. Generally, sewage is collected through pipes and discharged after passing through sewage treatment equipment.

[0003] In the related technology, the sewage treatment equipment includes a shell, a receiving groove is opened on the shell, a cleaning pipe, a movable structure, a scraper and a sewage box are arranged on the shell, the cleaning pipe is used to discharge cleaning agent into the sewage, a flexible plate is arranged on the shell, the sewage box is detachably connected to the shell, and the movable structure drives the scraper through the flexible plate, so that the scraper drives the oil and floating impurities above the sewage to be scraped into the sewage box through the flexible plate.

[0004] Since the scraper is prone to be attached with impurities such as oil during long-term use, it is easy to breed bacteria after long-term use, causing secondary pollution to the subsequent water quality and affecting the cleaning of sewage in the holding tank. Summary of the invention

[0005] In order to improve the problem that the scraper is prone to breeding bacteria, the present application provides a municipal sewage treatment equipment.

[0006] The municipal sewage treatment equipment provided in this application adopts the following technical solution: A municipal sewage treatment device comprises a shell, a receiving groove is provided on the shell, a movable structure, a scraper and a sewage box are provided on the shell, a flexible plate is provided on the shell, the movable structure is used to drive the scraper to move, the scraper scrapes impurities into the sewage box through the flexible plate, a cleaning block is slidably connected to the shell, the cleaning block is provided with a cleaning plate and a cleaning nozzle, the cleaning nozzle sprays cleaning liquid to the scraper, and the cleaning plate can scrape the surface of the scraper.

[0007] By adopting the above technical solution, the staff slides the cleaning block to allow the cleaning nozzle to spray cleaning liquid to the scraper, and the cleaning plate scrapes the surface of the scraper, so that the surface of the scraper can be cleaner, reducing the problem of oil and impurities adhering to the scraper surface, thereby making the scraper cleaner and reducing secondary pollution to the sewage when the scraper scrapes the sewage; the moving structure moves the scraper, allowing the scraper to move the impurities on the surface of the sewage toward the sewage box, and the flexible plate can limit the sewage from directly entering the sewage box, so that impurities can enter the sewage box, and the remaining sewage in the shell can be processed.

[0008] Optionally, a dovetail block is provided on the cleaning block, a dovetail groove for the dovetail block to slide is provided on the sewage discharge box, a through hole connected to the dovetail groove is provided on the sewage discharge box, and the through hole is for the dovetail block to pass through; when the dovetail block is located in the dovetail groove, the sewage discharge box is fixed on the shell; when the cleaning block slides, the cleaning block can clean the scraper.

[0009] By adopting the above technical solution, since the dovetail block is located in the dovetail groove, the cleaning block limits the sewage box. The staff needs to slide the cleaning block first. After sliding the cleaning block, the cleaning block can clean the scraper, so that the scraper can be cleaner. At this time, the dovetail block is located in the through hole, so that the dovetail block can be detached from the through hole, thereby releasing the restriction of the cleaning block on the sewage box, so that the sewage box can be detached from the shell, so that the sewage box can be taken out and cleaned, thereby reducing the number of times the staff cleans the scraper, so that the scraper can be kept in a relatively clean state.

[0010] Optionally, a stop plate is slidably connected to the sewage discharge box, and the stop plate is used to block the opening of the through hole; when the stop plate blocks the through hole, the dovetail block cannot pass through the through hole.

[0011] By adopting the above technical solution, the staff slides the stop plate to block the through hole, so that the stop plate can limit the dovetail block from detaching from the dovetail groove at the through hole, thereby allowing the stop plate to limit the movement of the sewage box. When the staff only cleans the scraper, the sewage box is not easy to detach from the shell, thereby enhancing the stability of the sewage box set on the shell.

[0012] Optionally, a drainage groove is provided on the drainage box, and a drainage cover is slidably connected to the drainage box. The drainage cover is used to block the drainage groove, and a connecting hole for a dovetail block to pass through is provided on the drainage cover.

[0013] By adopting the above technical solution, the sewage trough is sealed with a sewage cover. When the staff swings the sewage box, impurities inside the sewage trough are not easy to escape from the opening of the sewage trough, thereby avoiding the situation where impurities leak out during the transportation process of the staff and pollute the environment.

[0014] Optionally, the drain cover is slidably connected to a fixed block, and a fixing hole for inserting the fixed block is opened on the stop plate; when the fixed block is inserted into the fixing hole, the stop plate is fixed to the drain cover; when the drain cover completely blocks the drain groove, the stop block does not block the through hole.

[0015] By adopting the above technical solution, the fixing block is inserted into the fixing hole, and the hole wall of the fixing hole limits the fixing block, so that the sewage cover and the stop plate can be fixed to each other. When the staff slides the sewage cover, the stop plate can move synchronously, so that when the sewage cover completely blocks the sewage trough, the stop block will not block the through hole, thereby reducing the staff's operation of sliding the stop block again, reducing the staff's operating steps, and allowing the staff to take out the sewage box more quickly.

[0016] Optionally, the drain cover is provided with a fixing spring, the drain box is provided with a fixing groove for inserting a fixing block, and the fixing spring drives the fixing block to be inserted into the fixing groove; when the fixing block is inserted into the fixing groove through the fixing hole, the drain cover completely blocks the drain groove.

[0017] By adopting the above technical solution, the fixed block is inserted into the fixed groove through the fixing hole, and the groove wall of the fixed groove limits the fixed block, and the fixed block is driven to be inserted into the fixed groove by the fixing spring, so that the fixing spring drives the fixed block to be difficult to separate from the fixing groove, thereby reducing the possibility of movement of the sewage cover in the sewage box, and further increasing the stability of the sewage cover blocking the sewage groove.

[0018] Optionally, an operating block is provided on the fixing block, and an operating hole for the operating block to pass through is opened on the sewage discharge cover, and the operating block is used to drive the fixing block to disengage from the fixing hole.

[0019] By adopting the above technical solution, the staff can move the operating block, so that the operating block drives the fixed block to move, so that the fixed block can be disengaged from the fixed hole or the fixed groove, thereby releasing the lock of the sewage cover, and preventing the sewage cover from driving the stop plate to move, so that the sewage cover can be taken out of the sewage box for subsequent cleaning of the sewage box.

[0020] Optionally, a stop spring is provided on the stop plate, and the stop spring drives the stop block to block the through hole.

[0021] By adopting the above technical solution, the stop block is driven by the stop spring to block the through hole, so that the stop block is not easy to move at the through hole, and the stop plate can further stably block the through hole, thereby avoiding the situation where the stop plate fails to block the through hole due to equipment vibration, causing the sewage box to detach from the shell.

[0022] Optionally, a placement block is provided on the shell, and a placement groove is opened on the placement block for inserting the cleaning block, and the placement groove penetrates to the side of the placement block; when the cleaning block is located in the placement groove, the cleaning plate faces the side through which the placement groove penetrates.

[0023] By adopting the above technical solution, the cleaning block is arranged in the placement groove, and the cleaning plate is facing the side through which the placement groove passes, so that the staff can directly clean the cleaning plate through the opening in the direction through which the placement groove passes, thereby reducing the contamination of the cleaning plate caused by excessive scraping times; at the same time, the cleaning plate is usually located in the placement groove, so that the cleaning plate can be protected by the placement block, thereby reducing the problem of the cleaning plate being contaminated due to external debris touching the cleaning plate.

[0024] Optionally, a placement plate is slidably connected to the placement block, and the placement plate is used to block the opening of the placement slot passing through one side.

[0025] By adopting the above technical solution, the staff can slide the placement plate to allow the placement plate to block the opening on one side of the placement slot, so that external impurities are not easy to directly enter the placement slot through the opening on one side of the placement slot. When the cleaning plate is in the placement slot, the cleaning plate can be cleaner; at the same time, the staff only needs to slide the placement plate to open the opening on one side of the placement slot to facilitate the staff to clean the cleaning plate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The staff slides the cleaning block to allow the cleaning nozzle to spray cleaning liquid to the scraper, and the cleaning plate scrapes the surface of the scraper, so that the surface of the scraper can be cleaner, reducing the problem of oil and impurities adhering to the scraper surface, thereby making the scraper cleaner and reducing secondary pollution to the sewage when the scraper scrapes the sewage; the mobile structure moves the scraper, allowing the scraper to move the oil and other impurities on the surface of the sewage toward the sewage box, and the flexible plate can limit the sewage from directly entering the sewage box, so that impurities can enter the sewage box, so that the remaining sewage in the shell can be processed.

[0027] 2. Insert the fixing block into the fixing hole and let the wall of the fixing hole limit the fixing block, so that the sewage cover and the stop plate can be fixed to each other. When the staff slides the sewage cover, the stop plate can move synchronously, so that when the sewage cover completely blocks the sewage tank, the stop block will not block the through hole, thereby reducing the staff's operation of sliding the stop block again, reducing the staff's operating steps, and allowing the staff to take out the sewage box more quickly.
