Description

Technical Field

[0001] The invention relates to the technical field of sand mining ship equipment, in particular to a conveying type sand washing device for sand mining ships. Background Art

[0002] Normally, project construction requires that the sand source has a certain mud content, so it is usually necessary to wash the obtained sand source to remove excess mud. The sand source sucked in by the sand dredging ship contains a large amount of stones and other debris, so it needs to be filtered and screened. At the same time, due to the high mud content, sand washing is required. Therefore, it is necessary to build a sand washing platform on the sand dredging ship for sand washing.

[0003] Most of the existing sand washing devices are sand washing tanks installed on sand mining ships. The sand washing tanks are provided with chains for transmission, and several chain buckets are provided on the chains. The chain buckets are provided with filtering holes. When the chains are transmitted, the chain buckets are driven to move, and the sand is placed in the chain buckets. When the chain buckets are transmitted, the sand enters the sand washing tank, thereby washing the sand. This method causes the sand to be deposited in the chain buckets, and most of the sand is not effectively cleaned. Moreover, the water in the sand washing tank will become turbid after sand washing. If it is not replaced in time, the sand washing effect will also be affected. In addition, the sand and gravel need to be filtered and screened before sand washing, so as to screen out stones and other debris. Therefore, a special sand and gravel filtering device needs to be additionally equipped, which causes the sand washing equipment to occupy too large an area of ​​the sand mining ship, seriously squeezing the carrying capacity of the sand mining ship to transport sand, thereby affecting the working efficiency of the sand mining ship.

[0004] Therefore, we make improvements to this and propose a conveying type sand washing device for sand mining ships. Summary of the invention

[0071] Working principle of the present invention:

[0072] The sand and gravel taken by the sand dredging ship are poured into the feed hopper 4 through the sand dredging equipment of the sand dredging ship, and then washed into the vibration separation component 3 through the clean water sprayed from the flushing pipe 5, and the vibration separation component 3 vibrates and separates the sand and gravel;

[0073] The vibration motor 16 is started, and the vibration motor 16 drives the vibration frame box 8 and the vibration screen 9 to vibrate up and down in the upper inner cavity of the fixed bottom frame box 7. The nitrogen spring 10 and the vibration motor 16 cooperate with each other to realize the up and down vibration of the vibration frame box 8 and the vibration screen 9;

[0074] Under the vibration of the vibration separation component 3, the fine sand in the sand and gravel enters the upper surface of the guide plate B35 of the conveying component 2 through the sieve plate 12 of the vibrating screen 9, and then enters the bottom of the conveying component 2 under the flushing of the clean water for flushing the sand and gravel. The stones and other debris in the sand and gravel enter the waste chute plate 6 through the waste port 13, and then are discharged from the vibration separation component 3.

[0075] The fine sand enters the guide plate A32 from the guide plate B35 under the flushing of the clean water for flushing the sand and gravel, and then enters the bottom of the flushing bucket 23. The clean water for flushing the sand and gravel and the fine sand are placed at the bottom of the flushing bucket 23. The clean water for flushing the sand and gravel continues to soak and flush the fine sand at the bottom of the flushing bucket 23, and the soil particles in the fine sand are mixed with the clean water. When the water at the bottom of the flushing bucket 23 is at the bottom of the auger 25 and the lower side wall of the water filter screen 33, the flushing water mixed with soil particles is discharged.

The inclined bottom plate 37 and the inclined side plate 38 in the drainage component 1 can collect the clean water mixed with soil particles for washing sand and gravel to the side of the water tank 36 where the wastewater pipe 39 is connected to the water tank 36. The inclined bottom plate 37 and the inclined side plate 38 can prevent soil particles from accumulating in the water tank 36, and then the clean water mixed with soil particles for washing sand and gravel is discharged through the wastewater pipe 39.

[0076] The rotating motor 29 and the auger motor 30 are started, the auger motor 30 drives the auger 25 to work, the rotating motor 29 drives the stirring wheel 24 to rotate in the flushing bucket 23, and the stirring wheel 24 is rotated from one side of the flushing bucket 23 provided with a guide plate A32 toward the other side of the flushing bucket 23.
