Description

TECHNICAL FIELD

[0001] The utility model relates to a suction dredger technical field especially relates to a peripheral drive type suction dredger. BACKGROUND

[0002] Peripheral drive type suction dredger is mainly used for water supply or drainage engineering about 20m pool diameter radial flow type sedimentation tank. The water to be treated enters from the center cylinder inlet pipe, passes through the steady flow cylinder, enters the sedimentation tank, and then diffuses and deposits to the four corners. The clean water flows out from the pool edge overflow weir, and the sediment is collected by the mud scraping plate to the suction port, and then the suction pipe is used to discharge the sediment in the pool.

[0003] The existing document with the publication number CN222286487U discloses a peripheral drive type suction dredger, which solves the problem of blockage of the suction pipe by the blocky or sheety sediment when the suction pipe sucks up the scraped sediment, resulting in defects in the use of the peripheral drive type suction dredger. It includes a sedimentation tank, a channel platform is rotatably installed on the upper side of the sedimentation tank, a plurality of V-shaped scrapers are installed on the lower side of the channel platform, and the connection between the plurality of V-shaped scrapers is fixed connection, and the upper end of the V-shaped scraper is fixedly installed with a suction pipe; by installing the dispersing structure, the plurality of beaters rotate through the tooth groove on the inclined scraper to disperse the sheety or blocky sludge, which can effectively prevent the blocky or sheety sludge from blocking the suction pipe, and the connection assembly is installed, which is conducive to assisting the suction pipe to discharge sludge when backwashing the suction pipe.

[0004] However, when using this kind of suction dredger, it relies on the rubber wheels installed on both sides to contact the bottom of the sedimentation tank to obtain friction force to drive the beaters to rotate, and then cooperate with the inclined scraper to disperse the sludge. As we all know, the bottom of the sedimentation tank is relatively smooth under wet conditions, and the rubber wheel is pressed on the sludge, which is likely to slip, making it difficult for the beaters to obtain a large rotating force, and it is difficult to disperse the sheety or blocky sludge, so the stability of the equipment is poor.

DETAILED DESCRIPTION

[0024] The utility model will be further explained in combination with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples.

[0025] As Figures 1-4 The peripheral transmission type suction dredger provided by the utility model, including: sedimentation tank 1, walking platform 2 is rotatably installed on the sedimentation tank 1, and the driving mechanism is arranged between the edges of the sedimentation tank 1 of the walking platform 2, the driving mechanism can adopt the transmission structure of the existing peripheral transmission type suction dredger, be used to drive the walking platform 2 to rotate, and the specific structure and principle will not be repeated here, the scraper 3 is installed at the bottom of the walking platform 2, the suction pipe 4 is installed on one side of the scraper 3, the dividing mechanism is installed on the side of the scraper 3 that scrapes mud, the dividing mechanism includes the support plate 5 arranged below the walking platform 2, a plurality of connecting pieces 6 are arranged between the support plate 5 and the walking platform 1, a plurality of main cutting blades 7 are vertically installed at the bottom of the support plate 5, the plurality of main cutting blades 7 are uniformly installed, a plurality of secondary cutting blades 9 are obliquely installed on both sides of the main cutting blade 7, the bottom of the lowermost secondary cutting blade 9 is flush with the bottom of the main cutting blade 7, during use, the walking platform 2 rotates horizontally, the support plate 5 rotates along, and then the main cutting blade 7 rotates horizontally, the accumulated sludge block at the bottom of the sedimentation tank 1 is vertically divided, and the plurality of secondary cutting blades 9 shovel the cut sludge block and horizontally divide it, the sludge block is further divided into a plurality of small blocks with smaller volume, and the fragmented sludge is scraped by the rear scraper 3, the sludge is sucked through the suction pipe 4 and discharged through the pipeline.Compared with the scheme in CN222286487U, the structure in the embodiment is simpler, the cost is lower, the maintenance is convenient, does not rely on the friction force between the rubber wheel and the bottom of the sedimentation tank as the power source, and the crushing effect on the sheet-shaped or block-shaped sludge is more stable, which is more suitable for long-term use.

[0026] By setting the walking platform 2, the scraper 3 and the suction pipe 4 on the sedimentation tank 1, and setting the dividing mechanism including the support plate 5, the main cutting blade 7 and the secondary cutting blade 9 on one side of the scraper 3, the passive cutting of the main cutting blade 7 and the secondary cutting blade 9 can divide and cut the sheet-shaped or block-shaped sludge in front of the scraper 3 in advance, and the structure is simple, the cost is lower, and the stability is better.

[0027] Example 2:

[0028] like Figure 3 As shown, a vertical cutting blade 8 is provided on the main cutting blade 7, and a horizontal cutting blade 10 is provided on the secondary cutting blade 9. The vertical cutting blade 8 is used to vertically divide the sludge block, while the horizontal cutting blade 10 is used to horizontally divide the sludge block.

The top of the pressure relief hole 11 is the inlet, and its outlet is located at the tail of the secondary cutting blade 9 (on the side away from the horizontal cutting blade 10). When the multi-layered secondary cutting blades 9 horizontally cut the sludge block, the sludge between the secondary cutting blades 9 is divided and squeezed. A part of the sludge is squeezed out from the pressure relief hole 11 and enters the pressure relief hole 11, and then is discharged from the tail of the secondary cutting blade 9, thereby reducing the pressure of the sludge block between the secondary cutting blades 9, making it easier for it to pass between the secondary cutting blades 9 and less likely to cause blockage.

During use, by adjusting the length of the connector 6, the distance between the support plate 5 and the bottom of the sedimentation tank 1 can be adjusted, thereby adjusting the distance between the main cutting blade 7 and the bottom of the tank, ensuring its bottom just contacts the bottom, allowing the main cutting blade 7 to better and more thoroughly separate the sludge blocks. Similarly, when not in use, the support plate 5 can be raised, raising the main cutting blade 7 and removing it from contact with the sewage in the sedimentation tank 1, preventing corrosion of the main cutting blade 7 and the secondary cutting blade 9 by sewage, effectively improving their service life.

[0035] By setting an adjustable connector 6, the height of the support plate 5 can be easily adjusted, which is beneficial for cutting sludge blocks and extending the service life of the segmentation mechanism.

[0036] Working principle: when in use, the walking platform 2 rotates horizontally, the supporting plate 5 rotates with it, and then the main cutting piece 7 rotates horizontally, vertically cutting the sludge block accumulated at the bottom of the sedimentation tank 1, and the multiple secondary cutting pieces 9 shovel the cut sludge block and horizontally cut it, further dividing the sludge block into multiple small blocks with smaller volume, the fragmented sludge is scraped by the rear scraper 3, the sludge is sucked through the sludge suction pipe 4, and then discharged through the pipeline. The structure in the scheme is simpler, the cost is lower, the maintenance is convenient, it does not rely on the friction between the rubber wheel and the bottom of the sedimentation tank as the power source, the crushing effect on the sheet or block sludge is more stable, and it is more suitable for long-term use.
