Description

Technical Field

[0001] The invention relates to the technical field of sewage regulation, and in particular to a full-automatic self-cleaning mud scraper. Background Art

[0002] Whether it is industrial wastewater, urban sewage or domestic sewage, the water quantity and quality change within 24 hours a day. It is generally believed that for large and medium-sized urban sewage treatment plants, because their service area is large, the drainage changes of different types of buildings such as residences, shops, office buildings, and institutions in the area have different patterns and complementary effects. In addition, the sewage pipeline network has a balancing effect on water quantity and quality. Therefore, urban sewage treatment plants do not have regulating tanks. Regulating tanks are mainly used in industrial wastewater treatment stations as pretreatment structures to balance water quantity and water quality. They are used to regulate the inlet and outlet flow rates.

[0003] Sewage discharged by industrial enterprises and urban sewage, especially in places with concentrated population such as schools and residential areas, is prone to produce a large amount of sludge due to the uneven water consumption and impurities in the sewage. Therefore, the scraper is one of the necessary equipment in the sewage regulating tank. The existing scraper mainly collects the sludge into the central sludge collecting trough or the sewage discharge button, and discharges it out of the tank by hydrostatic pressure or pump. It should be noted that, on the one hand, the scraper blade of the existing scraper is fixed, the scraper blade has a large area, and sludge is easily attached to its outer surface. After working for a long time, it may increase the difficulty of scraping; on the other hand, due to the high viscosity of the sludge, the sludge moves slowly, resulting in a slow sewage discharge speed.

[0004] Therefore how to design a fully automatic self-cleaning scraper that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Summary of the invention

[0005] In order to solve the above problems, the object of the present invention is to provide a fully automatic self-cleaning scraper to increase the sewage discharge speed and clean the sludge adhering to the scraper assembly.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] See also Figure 1-2 As shown, a cleaning and scraping device 2 is installed in the sewage regulating tank 1 of the scheme; a mounting platform 11 is provided at the center of the sewage regulating tank 1, and a circular sewage outlet 12 is formed around the mounting platform 11; optimally, the bottom of the sewage regulating tank 1 is inclined from the periphery to the center to facilitate sewage discharge.

[0022] The cleaning and scraping mud device 2 includes a servo motor 21 fixedly mounted in the mounting platform 11, a central rotating shaft 22 connected to the output end of the servo motor 21, and a plurality of groups of scraping mud components 23 arranged at equal intervals along the circumference of the central rotating shaft 22 at the top of the central rotating shaft 22; the scraping mud components 23 each include a support rod 231 fixedly mounted vertically on the outer peripheral wall of the central rotating shaft 22, a first cleaning pipe 232 arranged parallel to and directly below the support rod 231, a first scraper 233 fixedly mounted on the outer peripheral wall of the first cleaning pipe 232, a second cleaning net pipe 234 arranged between the support rod 231 and the first cleaning pipe 232, a second scraper 235 fixedly mounted on the outer peripheral wall of the second cleaning net pipe 234, and a cylinder 236 fixedly mounted directly above the support rod 231 and corresponding to the position of the second cleaning net pipe 234. 36; the second cleaning net tube 234 is arranged at the end of the support rod 231 away from the central rotating shaft 22, one end of the second cleaning net tube 234 passes through the support rod 231 and extends to the top of the support rod 231 and is fixedly connected to the support rod 231, and the other end of the second cleaning net tube 234 is connected to the first cleaning tube 232; a cleaning block 2361 with the same diameter as the inner tube of the second cleaning net tube 234 is fixed at the output end of the cylinder 236, and a cleaning scraper 2362 is arranged on the outer peripheral wall of the cleaning block along its circumference; the first cleaning tube 232 includes a first cleaning net tube 2321 connected to the second cleaning net tube 234, a mounting tube 2322 arranged at the end of the first cleaning net tube 2321 away from the second cleaning net tube 234, and a screw feeder 2323 arranged on the mounting tube 2322.

[0023] The movable ends of the support rods 231 are fixed with pulleys 2311 . The upper end surface of the sewage regulating tank 1 is provided with a circle of slide rails 13 . The pulleys 2311 are all clamped in the slide rails 13 .

[0024] Furthermore, a discharge port 23211 is provided on the wall of the first cleaning network pipe 2321 at a position corresponding to the annular sewage discharge port 12 to facilitate the discharge of sludge.

[0025] Furthermore, the spiral shaft of the spiral feeder 2323 passes through the mounting tube 2322 and extends into the first cleaning mesh tube 2321 .

[0026] Furthermore, the first scraper 233 is arranged on the outer peripheral wall of the first cleaning network tube 2321 close to the side wall of the sewage regulating tank 1. The first scraper 233 is close to the inner wall of the sewage regulating tank 1.

[0027] Furthermore, the second scraper 235 is arranged on the outer peripheral wall of the second cleaning net pipe 234 close to the bottom of the sewage regulating tank 1. The second scraper 235 is close to the bottom of the sewage tank.

[0028] The working principle is roughly as follows:

[0029] The servo motor 21 drives the scraper assembly 23 to rotate. During the rotation, the first scraper 233 of the scraper assembly 23 is in close contact with the side wall of the sewage regulating tank 1 to scrape off the sludge on the side wall of the tank. Part of the sludge falls to the bottom of the tank under the action of gravity after being scraped off, and part of the sludge overflows into the second cleaning net pipe 234. At the same time, under the action of the cylinder 236, the extended end of the cylinder 236 reciprocates into the second cleaning net pipe 234. The cylinder 236 moving downward moves the sludge toward the bottom of the sewage regulating tank 1 and the first cleaning pipe 232. At the same time, the cleaning scraper 2362 on the outer peripheral wall of the cleaning block 2361 at the end of the extended end scrapes off the sludge attached to the net wall of the second cleaning net pipe 234.

[0030] At this time, the second scraper 235 of the scraper assembly 23 cleans the sludge on the bottom of the pool and the sludge that falls to the bottom of the pool. Most of the sludge is scraped away by the second scraper 235 and accumulates in the first cleaning net pipe 2321. It moves toward the discharge outlet 23211 of the first cleaning net pipe 2321 through the spiral feeder 2323, which speeds up the movement of the sludge to above the sewage discharge buckle and improves the sewage discharge efficiency. The remaining sludge naturally flows to the sewage discharge outlet during the discharge process.

[0031] After the scraping of mud is completed, the cylinder 236 in the second cleaning net tube 234 drives its extended end to reciprocate, so that the second cleaning net tube 234 can be self-cleaned.
