Description

Technical Field

[0001] The utility model belongs to the field of sewage lifters, and in particular relates to a sewage lifter which is convenient for slag discharge. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. The so-called raw sewage is the untreated domestic and industrial wastewater directly discharged from the city. The current utilization method is that raw sewage directly enters the sewage source heat pump system for heat exchange, which provides indoor cooling and heating for urban buildings while consuming a small amount of electricity.

[0003] A Chinese patent with announcement number CN214461074U discloses a sewage lift that is convenient for slag discharge, which includes a main shell, a water inlet pipe is fixedly installed on the side of the main shell, a support frame is fixedly installed on the top of the main shell, a motor is fixedly installed on the inner wall of the support frame, and two rotating shafts are arranged inside the main shell, and one end of the two rotating shafts passes through and extends to the outside of the main shell. The sewage lifter with convenient slag discharge has sewage entering through a water inlet pipe arranged on the main body shell, and then the sewage passes through a filter screen to filter out the slag therein, and then passes through a water outlet pipe and a water pump to discharge the sewage without slag through a delivery pipe to prevent the water pump from being blocked by the slag and affecting the normal use of the device. When the device is working, the float will float to a fixed position to raise the support rod, so that the water level in the device can be clearly observed to prevent sewage from overflowing from the device. However, in the sewage lifter with convenient slag discharge in this application, the slag not only easily blocks the filter screen, but also makes it impossible to discharge slag when the lifter is working. The slag can only be discharged completely after the sewage in the lifter is completely discharged, and the lifter operation is affected during slag discharge.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a sewage lifter which is convenient for slag discharge.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] A sewage lift for convenient slag discharge comprises a main shell, an arc-shaped filter screen is arranged inside the main shell, a partition plate is arranged at the first end of the arc-shaped filter screen, the partition plate divides the main shell into a sewage area and a slag storage area, a slag discharge valve connected to the slag storage area is arranged on the side of the main shell, a transmission shaft is rotatably fitted inside the arc-shaped filter screen, a plurality of scrapers are arranged in a circular array on the transmission shaft, and a servo motor for driving the transmission shaft is arranged on the outside of the main shell.

[0008] Optionally, an inclined plate is provided at the second end of the arc-shaped filter screen, and the inclined plate gradually descends from an end away from the arc-shaped filter screen to an end close to the arc-shaped filter screen. A water inlet pipe is connected to the side of the main body shell, and one end of the water inlet pipe extending into the main body shell is located above the inclined plate, so that sewage is discharged into the inclined plate in the main body shell through the water inlet pipe, and then flows into the arc-shaped filter screen through the inclined plate.

[0009] Optionally, a lifting pump is provided on the upper side of the main shell, and a lifting pipe is provided at the bottom end of the lifting pump. One end of the lifting pipe extends deep into the main shell and passes through the inclined plate to be connected with the sewage area, so as to facilitate opening the lifting pump to lift the sewage filtered in the sewage area through the lifting pipe and discharge it to the device.

[0010] Optionally, a first guide plate is provided on the bottom surface of the inner wall of the sewage area, and a second guide plate is provided on the bottom surface of the inner wall of the slag storage area. The height of the upper side of the first guide plate gradually decreases from far away from one end of the lifting pipe to close to one end of the lifting pipe, and the height of the upper side of the second guide plate gradually decreases from far away from one end of the lifting pipe to close to one end of the lifting pipe, so as to facilitate guiding the sewage to flow to the lifting pipe through the first guide plate and to facilitate guiding the slag to flow to the slag discharge valve by the second guide plate.

[0011] Optionally, the height of the first end of the arc filter is higher than the height of its axis, and the height of the second end of the arc filter is the same as the height of its axis, so that when the scraper rotates to the first end of the arc filter, the scraping surface of the scraper tilts downward.

[0012] Optionally, waterproof bearings corresponding to the transmission shaft are embedded on opposite sides of the main shell, and both ends of the transmission shaft are respectively fixed in the two waterproof bearings, so as to improve the rotation stability of the transmission shaft through the waterproof bearings.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] The sewage is discharged into the arc filter, and the servo motor drives the transmission shaft to drive the scraper to rotate, pushing the sewage between the two adjacent scrapers to be filtered on the arc filter, so that the filtered sewage and the incoming sewage can be separated by the scraper, so as to improve the sewage filtration efficiency and filtering effect. The sewage is filtered by the arc filter and discharged into the sewage area. When the scraper scrapes the filtered debris to the first end of the arc filter, the debris slides out of the arc filter along the inclined surface of the scraper and falls into the residue storage area, so as to continuously clean the arc filter, improve the filtration efficiency of the arc filter, and continuously filter the arc filter. The main shell is divided into a sewage area and a residue storage area by setting a dividing plate, so that when the lifter is working, the residue discharge valve can be opened to discharge the debris in the residue storage area, so as to improve the convenience and practicality of the use of the lifter.
