Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sewage discharge, in particular to a large-volume garbage interception device for a drainage pipeline used in municipal engineering. Background Art

[0002] Sewer pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. They include trunk pipes, branch pipes and pipes leading to treatment plants. No matter where they are built on the street or anywhere else, as long as they are used for drainage, they should be counted as sewer pipes.

[0003] The sewage in the municipal sewage pipe is collected by various sewage pipes. There are various types of garbage in the sewage. Smaller garbage can flow directly, while larger garbage will get stuck in the pipe mouth or pipe wall, thus affecting the smoothness of the pipe sewage discharge and increasing the maintenance cost.

[0004] When the existing sewage pipe is in use, such as the authorized patent CN217870893U, a garbage interception device for civil water supply and drainage pipes includes an interception pipe, the inner wall of the interception pipe is provided with a partition component, the right wall of the interception pipe is provided with a garbage pushing component, the left wall of the interception pipe is provided with an installation cavity, the installation cavity is provided with a garbage lifting component, and the surface of the garbage lifting component is provided with a garbage storage box. The garbage is intercepted by setting an interception plate and an interception pipe, and finally the garbage rises and is discharged after it is full. However, when the interception plate encounters larger garbage, it cannot handle it. The large garbage directly covers and blocks the filter holes of the interception plate, making it unable to play a role in passing water, thereby not only blocking the pipeline circulation, but also failing to intercept the pipeline garbage. Therefore, it is urgent to solve this problem. Utility Model Content

[0005] The main purpose of the utility model is to provide a large-volume garbage interception device for drainage pipes used in municipal engineering.

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, the present embodiment provides a large-volume garbage intercepting device for drainage pipes of municipal engineering, comprising a garbage collecting frame 1, wherein a driving shaft 15 is rotatably connected between the inner walls of the garbage collecting frame 1, and a discharging scraper 13 is threadedly connected to the outer wall of the driving shaft 15; a discharging trough 12 is integrally formed on one side of the top of the garbage collecting frame 1, and a toothed scraper 11 is correspondingly arranged directly above the discharging trough 12, and a filter screen 7 is installed on one side of the toothed scraper 11, and the filter screen 7 is made of stainless steel material with a smooth surface, which is convenient for the scraper to slide down and scrape, and is also beneficial to the circulation of sludge garbage.

[0025] The driving shaft 15 is connected to the first waterproof motor 2 on the outer wall of the garbage collection frame 1. Four groups of unloading scrapers 13 are installed on the outer wall of the driving shaft 15. The unloading scrapers 13 are solid metal supports with strong cutting ability, which can scrape the separated garbage into the bottom collection frame.

[0026] A filter screen 7 cover is detachably installed on the top of the garbage collection frame 1, and the discharge scraper 13 slides in contact with the groove on the top of the filter screen 7 cover, and also slides in contact with the inner wall of the discharge trough 12. The mesh on the top of the filter screen 7 cover is used to filter sewage and reduce the large volume of garbage collected at the bottom from overflowing again.

[0027] The toothed scraper 11 is slidably connected to the track 5 via a slider 6 welded on the back. The track 5 is fixed in the pipeline cement foundation layer 3, and the center of the pipeline cement foundation layer 3 runs through the sewage pipe body 4.

[0028] The filter screen 7 and the port of the sewage pipe body 4 are detachably mounted by screws. Slide frames 16 are welded on both sides of the top of the toothed scraper 11. The internal thread of the slide frame 16 is connected with a screw rod. The rotation of the screw rod can realize the lifting and lowering of the heavy-weight toothed scraper 11, and it has a self-locking function.

[0029] A belt drive assembly 10 is nested on the top of the screw rod, and a second waterproof motor 9 is fixedly installed on the bottom of the other end of the belt drive assembly 10. The belt drive assembly 10 and the second waterproof motor 9 are both installed in the basic soil layer around the sewage well through a fixing frame 8.

[0030] The toothed scraper 11 is made of heavy metal iron and is provided with a plurality of scraper grooves 11 a.

[0031] Working principle of this device:

[0032] Step 1: During the specific construction, the device is installed in the sewage well, the garbage collection frame 1 is located at the bottom of the sewage well, the first waterproof motor 2 is installed in the surrounding soil layer, and waterproof protection is done well, the fixing frame 8 and the second waterproof motor 9 are also installed in the surrounding soil layer, and waterproof protection is done well, and the screw rod is waterproof sprayed. As for use in the sewage well, the first waterproof motor 2 and the second waterproof motor 9 are connected to the municipal control buried line to facilitate remote control operation by the staff;

[0033] Step 2: During use, sewage enters the sewage well, is filtered from one side of the filter screen 7, and then enters the sewage pipe body 4. Smaller particles continue to flow through the mesh of the filter screen 7, and larger garbage and sludge garbage remain on the outer wall of the filter screen 7. The second waterproof motor 9 is controlled by remote operation to drive the belt drive assembly 10 to rotate, and then drive the screw rod to rotate. Using the lifting principle of the threaded screw rod, the sliding frame 16 slides up and down on the screw rod, driving the heavy-weight toothed scraper 11 to move downward. The toothed scraper 11 slides along the outer wall of the filter screen 7, and the sludge and large-volume garbage on the filter screen 7 can be scraped and washed away, and carried to the bottom through the scraper groove 11a;

[0034] Step 3: The scraper groove 11a is meshed with the gap of the discharge chute 12 at the bottom to separate the garbage, and then the toothed scraper 11 rises, the first waterproof motor 2 drives the drive shaft 15 to rotate, and the discharge scraper bar 13 rotates in the discharge chute 12 to scrape the scraped garbage into the garbage collection frame 1 again, keeping the top of the discharge chute 12 clean, and realizing a garbage filtering cycle. The garbage collection frame 1 opens the top cover of the filter screen 7 at regular intervals to take away the garbage.

[0035] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
